CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/177,013, filed May 11, 2009, entitled “Holder for Attachment to Chainlink Fence,” which is incorporated in its entirety herein. 
    
    
     FIELD OF THE INVENTION 
     The present invention is generally related to holders, and more particularly is related to a holder for attachment to a chain link fence. 
     BACKGROUND 
     Spectators and participants present at baseball games or similar sporting events or other such activities often consume beverages as they watch or participate. At such times, drinks in the form of bottles, cans, and similar containers are often placed on benches, atop fences, or on the ground. Drinks so placed are easily toppled and spilled, and frequently become muddy or soiled. Moreover, with only the drink itself to distinguish it from other drinks similarly placed in such locations, it is easy for a person to mistake his drink for that of someone else. 
     Chain link fences are common features at forums where sporting events are held. At such sporting events or other activities where a chain link fence is present, spectators will sometimes insert plastic cups, for example, into the meshwork holes of the chain link fence to spell out the name of their favored team or player. More generally, similar artifices have been used as a form of crude signage to communicate advertising, announcements, and various other textual messages and/or simple graphical content. However, where the improvised sign elements do not themselves contain lettering or other symbols but only form recognizable characters through arrangement in patterns of letters, numbers, or the like, even a concise message may require a large number of plastic cups or other such improvised sign elements, and insertion of such a large number of sign elements in the meshwork holes of the chain link fence may prove time-consuming. Furthermore, as such improvised sign elements such as plastic cups are often of such shape and dimensions as to make them only barely suitable for such purpose, it is not surprising to find that these improvised sign elements easily become dislodged from the chain link fence. 
     In addition, in situations where the so-called fabric of a chain link fence has diamond-shaped meshwork holes, it is typically the case that interweaving of the wire making up the chain link fence causes the wire at two sides of each such diamond-shaped hole to be in a different plane than the wire at the other two sides of the diamond-shaped hole. Proposed methods of mounting an object to a chain link fence that fail to account for this stepped topology of the chain link fence may suffer from drawbacks such as failure to securely grip the chain link fence wire at all four sides of the meshwork hole, unsightly skewing of signage or other object being attached to the chain link fence, as well as nonuniformity in alignment from sign element to sign element (or other such object being mounted to the chain link fence) due to chance variation in mounting when the direction of such skewing can vary depending on mounting orientation. 
     Therefore, there is a heretofore unaddressed need in the industry to address the aforementioned deficiencies and inadequacies, such as to provide a manner for securely holding items to fences. 
     SUMMARY 
     One aspect of the present invention is a holder apparatus for attaching items to a chain link fence. A chain link fence has generally diamond-shaped openings framed by two pairs of parallel wires. For each opening, a first pair of frame wires is in a shallow plane, and the second pair of frame wires is in a deep plane. The holder has a flat base having a fence attachment side which, when deployed, is adjacent to the fence, and a utility side opposite to the attachment side. The base is bounded by a perimeter having a perimeter edge. The apparatus attaches to the fence with two pairs of legs. Each leg has a proximate end that is attached to the attachment side of the base, and a wire engaging feature attached to the distal end of the leg. The legs are attached to the base at attachment points substantially within the base perimeter. A deep pair of legs attaches to the deep pair of frame wires, and a shallow pair of legs attaches to the shallow pair of frame wires. 
     The holder may attach to the fence by inserting both the shallow pair of legs and the deep pair of legs within a single diamond-shape hole in the chain link fence. The holder may be fastened to the fence by rotating the base approximately 45 degrees. The holder may have a rotation stop that prevents the holder from turning past 45 degrees. Alternatively, the holder may be formed of a semi-rigid material so that a leg can flex to facilitate insertion of the legs through a fence hole past the framing wires. Alternatively, the holder may be attached to the fence by inserting the first shallow leg and the first deep leg through a first diamond-shaped hole, and inserting the second shallow leg and the second deep leg through a second diamond-shaped hole. In one such embodiment, the base may be integral to the side of a bottle, with the utility side forming at least a portion of an interior wall of the bottle. 
     The engaging feature may be a lip that projects outward from the leg at an angle in a range between 30 and 90 degrees, such that the lip partially wraps around a framing wire. Or the engaging feature may have an upper lip and a lower lip projecting outward from the leg, with the upper lip and the lower lip being substantially parallel and spaced to form a groove to clasp a framing wire. The holder may be formed of a deformable elastic material, such as foam or sponge rubber. 
     The utility side of the holder base may be a substantially flat surface that may display a symbol, such that multiple holders may be used in concert to form a sign. The utility side may alternatively support a beverage holder. The beverage holder may have a ledge with a proximal portion attached to the base, a middle portion extending horizontally outward from the base for supporting a beverage container, and a distal portion that connects to the middle portion at an elbow. The ledge distal portion projects vertically upward from the middle portion and may further secure the beverage container. The ledge may have a first hinge located at the elbow and a second hinge connecting the ledge proximal portion to the ledge middle portion, allowing the ledge to fold up and collapse against the base. 
     In another embodiment, a portion of the utility side bears one component of a hook-and-loop fastener system, such Velcro® (registered trademark of Velcro Industries B.V. of Manchester, N.H., USA). In yet another embodiment, the base utility side has a tiedown loop that may be used to attach, for instance, a string or twine. 
     Another aspect of the current invention is a method for manufacturing a chain link fence fastener apparatus. The steps include forming a generally flat base having a fence attachment side and a utility side opposite the fence attachment side, and forming a plurality of legs, each leg having a proximal end attached to the base fence attachment side and a distal end projecting outward from the plane of the base. Each leg has a wire engaging feature attached to the distal end. The legs include a deep pair of legs having a first deep leg and a second deep leg and a shallow pair of legs having a first shallow leg and a second shallow leg, where the shallow pair of legs is shorter than the deep pair of legs. The forming step may involve injection molding, or blow molding. 
     Another aspect of the current invention is a system for attaching items to a chain link fence with a plurality of generally diamond-shaped openings, as described above. The system has a generally flat base with a fence attachment side and a utility side disposed opposite the fence attachment side, and a perimeter bounded by a base perimeter edge. As with the holder described above, the base fastens to the chain link fence with a deep pair of legs and a shallow pair of legs. The shallow pair of legs is shorter than the deep pair of legs, and each leg has a wire engaging feature attached to its distal end. The system includes a clasp for attaching a variety of removable holders to the base. The clasp includes a female member attached to the base utility fastener side, a clasp member removably attached to the female member, and a holder, attached to the clasp male member. The holder may be a beverage holder.

     DETAILED DESCRIPTION 
     The present invention provides a holder for attachment to a chain link fence. 
     A drink holder that snaps into and snaps out of a chain link fence in accordance with a first embodiment of the present invention is shown in  FIGS. 1 through 4 , a side view thereof being shown in  FIG. 1 , a front view thereof being shown in  FIG. 2 , a top view thereof being shown in  FIG. 3 , and a rear view thereof being shown in  FIG. 4 . Moreover, an enlarged side view of a portion of a snap-in/snap-out drink holder similar to that shown in  FIG. 1  is shown in  FIG. 5 . 
     Note that in the description that follows, except where otherwise clear from context, directions are defined in terms of the configuration of the holder  100  as it appears when installed on a chain link fence  50 , such that “back” or “rear” means in a direction toward the chain link fence  50  from the bulk of the holder  100 , “front” means in a direction opposite back, and “top” and “bottom” are defined relative to the vertical, as a drink would typically be placed in a drink holder  100  in such orientation relative to the vertical as to avoid spillage by aligning the top, or opening, of the drink with the top of the holder, and by aligning the bottom, or end opposite the top, of the drink with the bottom of the drink holder  100 . 
     Referring to  FIGS. 1 through 3 , the drink holder  100  in accordance with the first embodiment of the present invention contains a base  120  having a back face  110  that faces the chain link fence  50  when the holder  100  is installed on the chain link fence  50 . Extending approximately perpendicularly from the back face  110  of the base  120  are two pairs of legs  102 ,  104  that engage with the wires making up the meshwork of the chain link fence  50  when the holder  100  is installed thereon. 
     Extending from the bottom of the base  120  when the holder  100  is in its installed configuration is a ledge-like projection that projects frontward to form a floor for placement of a drink thereon. In the present embodiment, this ledge-like floor contains a proximal portion  130 , a middle portion  140 , and a distal portion  150 , hinges  160  between the proximal portion  130  and the middle portion  140 , and between the middle portion  140  and the distal portion  150 , allowing the floor to be collapsed as shown by the arrows in heavy outline at  FIG. 1 . In collapsing the floor of the holder  100  shown in  FIG. 1 , the distal portion  150  would first be folded down onto the middle portion  140 , and the middle portion  140  together with the distal portion  150  would then be folded up against the proximal portion  130 . When the floor is collapsed in such fashion, the more or less flat profile of the holder facilitates transport and storage. Deployment of the hinged floor of the drink holder  100  is carried out by performing these steps in reverse. Although the floor is shown as hinged here, there is no particular objection to employment of a solid floor. Furthermore, as best seen at  FIG. 3 , the distal portion  150  in the present embodiment preferably forms a more or less arcuate guide that facilitates insertion of a drink therewithin and helps prevent such a drink from falling out therefrom. 
     Extending from the top of the base  120  when the holder  100  is in its installed configuration is a cap-like projection that projects frontward at a slight angle upward relative to a perpendicular drawn frontward from the plane of the back face  110  so as to form a roof  170  for additional guidance and support of a drink when the drink is placed in the drink holder  100 . 
     Referring now to  FIGS. 4 and 5 , the manner in which the legs  102 ,  104  grip the wire of the chain link fence  50  when the holder  100  is attached to the chain link fence  50  will be described in further detail. 
     As best seen at  FIG. 4 , a typical chain link fence  50  contains a so-called fabric portion made up of wire interwoven so as to form meshwork in which holes are present. For example, a typical chain link fence  50  might have a fabric portion made up of 9 gauge (approximate diameter 0.15 inch) galvanized stainless steel that is interwoven to form meshwork having 2 inch×2 inch diamond-shaped holes, which is to say that the meshwork holes are 2 inches on a side. Although this example has been given for illustrative purposes, there is no particular objection to use of wire of different material and/or different gauge to form meshwork having holes of the same or different size and/or shape, with appropriate modifications being made to the dimensions of the holder  100  so as to accommodate the holes in the meshwork of the chain link fence  50 . 
     Interweaving of the wire that makes up the chain link fence  50  as shown at  FIG. 4  causes the wire at two sides of each such diamond-shaped hole to be in a different plane than the wire at the other two sides of the diamond-shaped hole. For example, at  FIG. 4 , the wire at the top left and at the bottom right in the drawing will extend further out of the plane of the paper toward the reader than the wire at the top right and at the bottom left in the drawing. That is, since  FIG. 4  is a rear view of the holder  100  shown in  FIGS. 1 through 3 , an enlarged side view of a portion of which is moreover shown in  FIG. 5 , the pair of legs  104 ,  104  that engage with the wire at the top left and at the bottom right in  FIG. 4  will preferably extend further from the base  120  of the holder  100  than the pair of legs  102 ,  102  that engage with the wire at the top right and at the bottom left in  FIG. 4 . For this reason, in the present embodiment, one pair of legs will be referred to as deep legs  104 ,  104 , and the other pair of legs will be referred to as shallow legs  102 ,  102 . Note that the term “wire” or “the wire” is generally used in a collective sense herein, no distinction being made with respect to singular or plural or to which strand of wire it is that is actually engaging with which leg of the holder  100 ; that is, strictly speaking, at  FIG. 4 , the strand of wire at top left is the same strand of wire as at bottom left, and the strand of wire at top right is the same strand of wire as at bottom right, but for ease of description, reference is consistently made herein simply to “wire” or “the wire” in the collective sense of the word, without intending to distinguish whether it is one strand or two, or whether it is the same or a different strand, that is being referred to. 
     This difference in extension of the shallow legs  102 ,  102  and the deep legs  104 ,  104  from the back face  110  of the base  120  to permit engagement with wire at different depths in the topology of the chain link fence  50  is more readily apparent in the side view of  FIG. 1  and the top view of  FIG. 3 . 
     Before continuing, the reader should be cautioned about a liberty taken in the drawings with regard to portrayal of the chain link fence  50 . At the side views of  FIGS. 1 ,  5 ,  7 ,  9 ,  10 , and the top view of  FIG. 3 , note that interweaving of strands of wire in the chain link fence  50  has not been shown as it would actually appear, e.g., as two strands weaving in and out to left and to right as one goes from top to bottom of the chain link fence  50 , but has instead been simplified and approximated by portrayal as closed loops (after the fashion of welded chain) in the drawings. For example, the actual situation of interweaving of wire in a chain link fence  50  is shown more closely in  FIG. 15 . The reader should take note that notwithstanding this simplified portrayal of the meshwork of the chain link fence  50 , the holder  100  of the present embodiment is in fact intended to be attached to chain link fence  50  having interwoven strands. 
     Returning to  FIGS. 4 and 5 , the manner in which the legs  102 ,  104  of the holder  100  grip the wire of the chain link fence  50  will now be described.  FIG. 4  is a partial rear view of the drink holder  100  shown in  FIGS. 1 through 3 .  FIG. 5  is an enlarged side view of a portion of the drink holder  100  shown in  FIGS. 1 through 4 . 
     Referring to  FIG. 5 , the topology of the chain link fence  50  is such that the wire making up the meshwork of a typical interwoven chain link fence  50  will lie predominantly in two planes, as has been mentioned. As measured from the plane of the back face  110  of the base  120  of the holder  100 , it can be seen that the wire of such a chain link fence  50  lies in a near plane and a far plane. The near (shallow) plane of the chain link fence  50  corresponds to the shallow legs  102 ,  102  of the holder  100 . The far (deep) plane of the chain link fence  50  corresponds to the deep legs  104 ,  104  of the holder  100 . That is, at the rear view of  FIG. 4 , it can be seen that the shallow legs  102 ,  102  of the holder  100  engage with wire in the shallow plane of the chain link fence  50 . More specifically, shallow engaging features  101 ,  101  on the shallow legs  102 ,  102  engage with the wire in the shallow plane of the chain link fence  50 . Moreover, it can be seen at  FIG. 4  that the deep legs  104 ,  104  of the holder  100  engage with wire in the deep plane of the chain link fence  50 . More specifically, deep engaging features  103 ,  103  on the deep legs  104 ,  104  engage with the wire in the deep plane of the chain link fence  50 . 
     As best understood by referring to the dimensions indicated in the upper portion of  FIG. 5 , a shallow plane depth  51  is here taken to be approximately a distance from the plane of the back face  110  of the base  120  of the holder  100  to a centerline  52  (hereinafter “shallow plane wire centerline  52 ”) of the wire lying in the shallow plane of the chain link fence  50 . Furthermore, a deep plane depth  53  is here taken to be approximately a distance from the plane of the back face  110  of the base  120  of the holder  100  to a centerline  54  (hereinafter “deep plane wire centerline  54 ”) of the wire lying in the deep plane of the chain link fence  50 . For example, a chain link fence  50  made up of 9 gauge wire interwoven to form diamond-shaped holes that are 2 inches on a side might have a shallow plane depth  51  of approximately 0.07 inch (roughly one half of the diameter of the chain link fence wire), and might have a deep plane depth  53  of approximately 0.57 inch. The difference between the shallow plane depth  51  and the deep plane depth  53  in such an example would be approximately 0.5 inch. 
     Depending on the engaging features  101 ,  103  employed, the holder  100  may be designed such that the back face  110  of the base  120  of the holder  100  is more or less flush with (abutting) the wire in the near plane of the chain link fence  50  when the holder  100  is in its installed configuration as shown in the views at  FIGS. 1 ,  3 , and  5 , in which case the shallow plane depth  51  will be approximately one half of the diameter of the wire of the chain link fence  50  (approximately 0.07 inch in the present example). Moreover, in holders  100  designed for flush installation, it may be preferred that the back face  110  of the base  120  be made planar. Such a flush configuration may be preferred, for example, when the back face  110  of the base  120  of the holder  100  cooperates with the engaging features  101 ,  103  to locate and/or secure the holder  100  in place relative to the chain link fence  50 . For example, where splayed tabs are employed as engaging features  101 ,  103 , such as is the case in the example shown in  FIGS. 1 through 5 , a flush installed configuration may be preferred so as to prevent play in the front-to-back direction when the holder  100  is installed on the chain link fence  50 . This will typically be the case where such tabs serve as engaging features  101 ,  103  to prevent movement of the holder  100  in a frontward direction, but not necessarily to prevent movement of the holder  100  in a rearward direction, when the holder  100  is in its installed configuration. 
     Alternatively, for example where grooves disposed at the outside circumferential surface of the legs  102 ,  104 , such grooves having radius of curvature not less than the radius of curvature of the wire of the chain link fence  50 , are employed as engaging features  101 ,  103  for engagement with the wire of the chain link fence  50 , to the extent that such grooves may act to prevent movement of the holder  100  in both a frontward and a rearward direction when the holder  100  is in its installed configuration, because cooperation with the back face  110  of the base  120  of the holder  100  may in such case not be necessary to locate and/or secure the holder  100  in place relative to the chain link fence  50 , there would be no particular objection to employment of a standoff distance separating the back face  110  of the base  120  of the holder  100  from the chain link fence  50 . That is, in such case, there would be no particular objection to employment of a shallow plane depth  51  that is greater than one half of the diameter of the wire of the chain link fence  50  (approximately 0.07 inch in the present example). Where such a standoff distance is employed, it will generally be preferred to increase the deep plane depth  53  by a corresponding amount so as to more or less maintain a constant difference between the deep plane depth  53  and the shallow plane depth  51  (approximately 0.5 inch in the present example) so as that the plane of the back face  110  of the base  120  of the holder  100  is more or less parallel with the plane of the chain link fence  50 , and holder features such as the floor  130 ,  140 ,  150  and the roof  170  project frontward in more or less perpendicular fashion with respect to the plane of the chain link fence  50 . 
     However, regardless of the type of engaging features  101 ,  103  employed, it is preferred that the difference in depth (magnitude of extension toward the chain link fence  50  in a direction perpendicular to the back face  110  of the base  120  of the holder  100 ) between the shallow engaging features  101 ,  101  on the shallow legs  102 ,  102  and the deep engaging features  103 ,  103  on the deep legs  104 ,  104  be chosen so as to more or less correspond to the difference between the shallow plane depth  51  and the deep plane depth  53  of the chain link fence  50 , this difference being approximately 0.5 inch in the present example. This will allow the shallow and deep engaging features  101 ,  103  to engage with the wire in the shallow and deep planes of the chain link fence  50  when the holder  100  is in its installed configuration. 
     When the holder  100  of the first embodiment is installed on a chain link fence  50 , the legs  102 ,  104  engage with the wire making up the meshwork of the chain link fence  50  so as to hold the base  120  of the holder  100  securely to the chain link fence  50 . The legs  102 ,  104  are therefore preferably arranged in a pattern more or less corresponding to the dimensions of the meshwork hole in the chain link fence  50 . For example, as best seen at  FIG. 4 , for a nominal 2 inch×2 inch hole as in the present embodiment, the distance between the respective shallow legs  102 ,  102  is preferably on the order of 2 inches, and the distance between the respective deep legs  104 ,  104  is likewise preferably on the order of 2 inches. 
     More subtly, the respective legs  102 ,  104  in some embodiments have engaging features  101 ,  103  near their ends or at other suitable locations, and depending on the manner in which these engaging features  101 ,  103  are intended to work, it may be the case that the critical surfaces of the engaging features  101 ,  103  on each pair of legs  102 ,  104  are preferably mutually separated, when in their undeflected state, by a distance that is slightly less than or slightly more than the nominal 2 inch hole size. What is meant here by the critical surfaces of the engaging features  101 ,  103  may vary somewhat depending on the specific design of such engaging features  101 ,  103 , but in general such critical surfaces include the surfaces of the legs  102 ,  104  that make contact with the wire of the chain link fence  50  when the holder  100  is in its installed configuration. 
     For example, at  FIGS. 1 through 5  but best seen at  FIGS. 4 and 5 , tab-like bends of approximately 90 degrees may be employed as engaging features  101 ,  103 , these tabs being splayed outward in the embodiment shown in  FIG. 5 , which is to say that that the outside circumferential surface of the legs  102 ,  104  are intended in the present embodiment to contact the inside circumferential surface of the diamond-shaped meshwork hole in the chain link fence  50  (such an arrangement is referred to herein as an “outwardly sprung” configuration). Of course, such tabs may alternatively be splayed inward, in which case it would be the inside circumferential surface of the legs  102 ,  104  that would be intended to contact the outside circumferential surface of the diamond-shaped meshwork hole in the chain link fence  50  (such an arrangement is referred to herein as an “inwardly sprung” configuration). In some embodiments, alternatively or in addition to such tabs, grooves may be employed as engaging features  101 ,  103 , with critical surfaces being defined similarly. Of course, there is no objection to employing tabs on some legs  102 ,  104  and grooves on other legs  102 ,  104  of the same holder  100 , and there is likewise no objection to having one pair of legs  102 ,  104  be inwardly sprung while the other pair of legs  102 ,  104  is outwardly sprung. Note that where “inside circumferential surface” and “outside circumferential surface” are said above, this is not to imply that such surfaces necessarily have circular cross-section, as these terms are used merely as a convenient way to indicate what is radially inside and what is radially outside, regardless of exact shape. 
     In embodiments having inwardly sprung and/or outwardly sprung pairs of legs  102 ,  104 , the material and dimensions of the legs  102 ,  104  are preferably chosen so as to impart the legs  102 ,  104  with elasticity sufficient to allow respective pairs of legs  102 ,  104  to flex in a direction that increases or decreases the separation between the critical surfaces of the engaging features  101 ,  103  relative to the undeflected state so as to produce a restoring force suitable for locating and/or gripping the holder  100  to the chain link fence  50 . That is, where elasticity of the legs  102 ,  104  is utilized in outwardly sprung or inwardly sprung designs, separation between such critical surfaces is preferably chosen to achieve a suitable restoring force such as will allow easy installation and removal but will also permit secure attachment when the holder  100  is installed on the chain link fence  50 . 
     For example, in the embodiment shown in  FIGS. 1 through 5 , the respective critical surfaces of the outwardly sprung tab-like bends that serve as shallow engaging features  101 ,  101  at the ends of the shallow legs  102 ,  102  are preferably separated, when in their undeflected state, by a distance that is somewhat greater than the nominal meshwork hole size so as to provide an appropriate restoring force for easy installation and removal but also permit secure attachment when the holder  100  is installed on the chain link fence  50 . Similarly, the respective critical surfaces of the outwardly sprung tab-like bends that serve as deep engaging features  103 ,  103  at the ends of the deep legs  104 ,  104  are preferably separated, when in their undeflected state, by a distance that is somewhat greater than the nominal meshwork hole size. 
     Procedures for installation and removal will vary depending on the design employed. For example, the holder  100  having outwardly sprung tab-like bends as engaging features  101 ,  103  in the embodiment shown in  FIGS. 1 through 5  may be installed and removed in straight-in/straight-out fashion or in twist-in/twist-out fashion. 
     In straight-in/straight-out (or snap-in/snap-out) installation, the holder  100  is aligned with the chain link fence  50  so that the shallow legs  102 ,  102  are directly in front of wire in the shallow plane of the chain link fence  50 , and the deep legs  104 ,  104  are directly in front of wire in the deep plane of the chain link fence  50 , and the holder  100  is pressed straight into the meshwork hole of the chain link fence  50 . Removal is the reverse of installation. Note that where it is said herein that a holder  100  is inserted into a meshwork hole of the chain link fence  50 , this is used as shorthand to mean that the holder  100  is installed on the chain link fence  50 , regardless of whether contact between engaging features  101 ,  103  and wire occurs at the inside circumferential surface or the outside circumferential surface of the meshwork hole; i.e., the holder  100  is said to be inserted into the meshwork hole regardless of whether the legs  102 ,  104  employ an inwardly sprung design or an outwardly sprung design or a design that is neither inwardly sprung nor outwardly sprung. Moreover, the procedure for straight-in/straight-out installation would essentially be the same for holders having inwardly sprung tabs, and for holders having grooves instead of or in addition to tabs. 
     During twist-in/twist-out installation, the holder  100  is first held in an orientation that is rotated approximately 45 degrees counterclockwise or clockwise relative to the straight-in/straight-out orientation (i.e., the legs  102 ,  104  are first aligned with the corners of the diamond-shaped meshwork hole), and the holder  100  is then pressed straight into the meshwork hole and rotated 45 degrees clockwise or counterclockwise (i.e., in a direction that will cause the shallow engaging features  101 ,  101  of the shallow legs  102 ,  102  to engage with the wire in the shallow plane of the chain link fence  50 , and will cause the deep engaging features  103 ,  103  of the deep legs  104 ,  104  to engage with the wire in the deep plane of the chain link fence  50 ). Removal is the reverse of installation. For twist-in/twist-out installation, it is preferred that the dimensions of the legs  102 ,  104  be such as to allow the legs  102 ,  104  to clear the inside circumferential surface of the meshwork hole when the legs  102 ,  104  are aligned with the corners of the diamond-shaped hole and pressed straight thereinto. Note, moreover, that it is impractical to employ a sprung inward design for twist-in/twist-out installation. 
     Especially for straight-in/straight-out installation, it is preferred that tabs, groove walls, ridges or other such engaging features  101 ,  103  protrude radially (as viewed, for example, in  FIG. 4 ) no more than necessary for locating and/or securing of the holder  100  relative to the chain link fence  50 , and it is moreover preferred that such regions proximate to such engaging features  101 ,  103  be tapered, chamfered, or beveled at appropriate locations so as to facilitate installation and removal. Furthermore, as can be seen at the front and rear views of  FIGS. 2 and 4 , note that the base  120  of the holder  100  may have features, such as a hole in the center of the base and/or cutouts at the periphery of the base  120 , between neighboring legs  102 ,  104 , that serve as handholds or locations where fingers can be placed to facilitate pressing, pulling, twisting, and other motions employed during installation and removal. 
       FIG. 6  collectively shows a top view,  FIG. 6A , a rear view,  FIG. 6B , and a side view,  FIG. 6C , of a holder  700  in accordance with a first variation on the holder  100  of the first embodiment described with reference to  FIGS. 1 through 5 . To the extent that the holder  700  in accordance with this first variation described with reference to  FIG. 6  is similar in structure and/or function to the holder  100  of the first embodiment described above with reference to  FIGS. 1 through 5 , like parts are given like-numbered reference numerals and description thereof is omitted for brevity. 
     The embodiment shown in  FIG. 6  is a variation on a design intended for twist-in/twist-out installation. For example, helical, tapered, chamfered, or beveled surfaces near the ends of the legs  702 ,  704  in the present variation may approximate helical surfaces after the fashion of screw threads so as to impart directionality to the rotation of the holder  700  as it is twisted in or twisted out of the chain link fence  50 , guiding and facilitating engagement of engaging features  701 ,  703  with the wire of the chain link fence  50  or disengagement of the engaging features  701 ,  703  therefrom. For example, as a variation on the use of grooves as engaging features  701 ,  703  mentioned above, such grooves may be straight (parallel with the wire of the chain link fence  50 ) where they are designed to engage with the wire of the chain link fence  50  but curve to on the order of between 30 degrees and 60 degrees at the ends of the legs  702 ,  704  (i.e., toward the rear of the chain link fence  50  when the holder  700  is installed thereon) so as to open out at leg ends and more readily accept the wire of the chain link fence  50  during twist-in/twist-out installation. That is, in embodiments without such guide features, rearward portions (i.e., portions near ends of legs) of engaging features  701 ,  703  may interfere with insertion of the holder  700  into the chain link fence  50 . For example, where a groove is employed as an engaging feature  701 ,  703 , a ridge formed by the groove wall toward the end of the leg  702 ,  704  in some embodiments might interfere with insertion of the holder  700  into the chain link fence  50 . Presence of helical, tapered, chamfered, or beveled surfaces, especially in combination with twist-in/twist-out installation, can therefore help to guide and facilitate entry of the holder  700  into and out of the meshwork hole of the chain link fence  50 . Note that where entry of the holder  700  into the chain link fence  50  is said here, this is used as shorthand to refer to sliding contact of the outside circumferential surface of the legs  702 ,  704  with the inside circumferential surface of the wire bounding the meshwork hole of the chain link fence  50 , or sliding contact of the inside circumferential surface of the legs  702 ,  704  with the outside circumferential surface of the wire bounding the meshwork hole of the chain link fence  50  (but note that sliding contact of the outside circumferential surface of the legs  702 ,  704  with the inside circumferential surface of the wire of the chain link fence  50  will be the preferred mode of operation for twist-in/twist-out installation). 
     Furthermore, optional presence of one or more stops that halt rotation during twist-in installation when the holder  700  has reached its installed configuration, and the engaging features  701 ,  703  of the legs  702 ,  704  are properly aligned and engaged with the wire of the chain link fence  50 , can further facilitate proper engagement of engaging features  701 ,  703  with the wire of the chain link fence  50 , serving as a positive stop to definitively indicate that the holder  700  is properly engaged with the chain link fence  50 , and thus helping to prevent the holder  700  from being underrotated short of, or overrotated past, its preferred installed orientation. 
     The holders  100 ,  700  in accordance with the first embodiment and the first variation thereon may be manufactured using any suitable method from any suitable material or materials. For example, the holders  100 ,  700  in accordance with the first embodiment and the first variation thereon may be molded from thermoplastic or thermosetting resin. Furthermore, there is no particular objection to using different materials for different parts and joining the parts by bonding or any other suitable method. As mentioned above, where the legs of the holder are of sprung inward or sprung outward design, it is preferred that material and dimensions be chosen so as to provide an appropriate restoring force such as will allow easy installation and removal but will also permit secure attachment when the holder is installed on the chain link fence  50 . 
     Referring to  FIG. 7 , this shows a side view of a holder  200  in accordance with a second variation on the holder  100  of the first embodiment described with reference to  FIGS. 1 through 5 . To the extent that the holder  200  in accordance with this second variation described with reference to  FIG. 7  is similar in structure and/or function to the holder  100  of the first embodiment described above with reference to  FIGS. 1 through 5 , like parts are given like-numbered reference numerals and description thereof is omitted for brevity. 
     In the variation shown in  FIG. 7 , a bottle portion  205  is integral with legs  202 ,  204  similar to the legs  102 ,  104  described with reference to  FIGS. 1 through 5 . Note that employment of an integral design such as is shown in the drawing permits certain of the features described with reference to  FIGS. 1 through 5 , such as the base  120 , the floor  130 ,  140 ,  150 , the hinges  160 , and the roof  170  in the first embodiment shown in  FIGS. 1 through 5 , to be omitted or subsumed into the integral design of the present variation. 
     To avoid spilling of drink from the bottle portion  205  when the cap of the bottle portion  205  has been removed, straight-in/straight-out installation will be preferred. 
     The holder  200  in accordance with the second variation on the first embodiment may be manufactured using any suitable method from any suitable material or materials. For example, the integral holder  200  of the second variation on the first embodiment may be molded as one piece from thermoplastic or thermosetting resin such as any of a variety of resins appropriate for molding of drink containers. Furthermore, although the holder of the present variation is referred to as an integral holder  200 , in accordance with a further variation thereon there is no particular objection to using different materials for different parts and joining the parts by bonding or any other suitable method. For example, although it may be preferred, where the legs of the holder are of sprung inward or sprung outward design, to employ thermoplastic or thermosetting resin for the legs  202 ,  204  so as to have elasticity sufficient to obtain a suitable restoring force as explained above, there is no particular objection to using metal or other such harder material for the bottle portion  205 , with the two materials being joined by an appropriate method. 
     Referring to  FIG. 8 , this shows a front view of a holder  300  in accordance with a second embodiment of the present invention. Moreover, a side view of this holder  300  in accordance with the second embodiment is shown in  FIG. 9 . To the extent that the holder  300  in accordance with the second embodiment described with reference to  FIGS. 8 and 9  is similar in structure and/or function to the holder  100  of the first embodiment described above with reference to  FIGS. 1 through 5 , like parts are given like-numbered reference numerals and description thereof is omitted for brevity. 
     Before proceeding with description of the second embodiment with reference to  FIGS. 8 and 9 , the reader should be cautioned on a couple of points bearing on how the second embodiment is portrayed in  FIGS. 8 and 9 . 
     The first point on which to caution the reader is that, upon comparing  FIGS. 8 and 9 , it may be noted that the dog ears  312 ,  314  at the top of the holder  300 , which appear to be respectively angled approximately 45 degrees to either side of the vertical as seen in the front view of  FIG. 8 , appear in the side view of  FIG. 9  to respectively be almost 90 degrees from the vertical such that the dog ears  312 ,  314  in  FIG. 9  are approximately 180 degrees apart so as to almost be in a horizontal line. For purposes of the present description, the approximately 45-degree angled configuration shown in  FIG. 8  is taken as accurate, the reader being asked to adjust in his mind&#39;s eye the geometry shown in  FIG. 9  to conform to the configuration shown in  FIG. 8 . 
     Another point on which to caution the reader is with respect to the dimensions of the dog ears  312 ,  314  at the top of the holder  300  relative to the size of the holes in the meshwork of the chain link fence  50  as seen in  FIG. 8 . That is, as will be described below, the holder  300  of the second embodiment is designed to angle-in and angle-out of the chain link fence  50 . Borrowing from aeronautical terminology, angle-in and angle-out as used here predominantly refers to angled motion in the “pitch” direction. However, as seen in the front view of  FIG. 8 , the distance between the corner at far left of the top shallow dog ear  312  and the corner at far right of the top deep dog ear  314  appears slightly wider than the diagonal of the diamond-shaped meshwork hole of the chain link fence  50 , meaning that during insertion there would also necessarily be some angled motion in the “yaw” direction so as to be able to cause the top dog ears  312 ,  314  to clear the edges of the meshwork hole as the holder  300  is inserted in or removed from the chain link fence  50 . One of skill in the art will appreciate that with slight modification to the top dog ears  312 ,  314  of the holder  300  it would be possible to insert the holder  300  into the meshwork hole of the chain link fence  50 , and remove the holder  300  therefrom, with only angled motion in the “pitch” direction. For example, the aforementioned corner at far left of the top shallow dog ear  312  and corner at far right of the top deep dog ear  314  could be removed, the lengths of the top dog ears  312 ,  314  could be shortened, the respective angles of the top dog ears  312 ,  314  relative to the vertical could be made shallower, the widths of the top dog ears  312 ,  314  could be made more narrow, and/or the locations at which the top dog ears  312 ,  314  emerge from the base  320  could be shifted upward in inclined fashion along their present angles with respect to the vertical as viewed in  FIG. 8  so that the aforementioned corner at far left of the top shallow dog ear  312  and corner at far right of the top deep dog ear  314  do not respectively extend beyond lines drawn parallel to the sides at the central portion of the base  320 . 
     Instead of shallow legs  102 ,  102  and deep legs  104 ,  104  as at the holder  100  of the first embodiment shown in  FIGS. 1 through 5 , the holder  300  of the second embodiment shown in  FIGS. 8 and 9  has a top shallow dog ear  312  and a top deep dog ear  314 , and has a bottom shallow stop  317  and a bottom deep stop  319 . 
     Moreover, the holder  300  of the second embodiment shown in  FIGS. 8 and 9  has a floor  330  and a roof  370 . To emphasize the fact that the holder  300  of the second embodiment may be capable of supporting heavy objects without becoming dislodged from the chain link fence  50  as a result of rotation in the “pitch” direction due to torque thereon caused by the force of gravity, the floor  330  and the roof  370  of the second embodiment are hook-like in shape so as to permit a heavy object such as a duffle bag to be suspended therefrom. 
     The top shallow dog ear  312  of the second embodiment shown in  FIGS. 8 and 9  is similar to one of the shallow legs  102  of the first embodiment shown in  FIGS. 1 through 5 , and the top deep dog ear  314  of the second embodiment shown in  FIGS. 8 and 9  is similar to one of the deep legs  104  of the first embodiment shown in  FIGS. 1 through 5 , in that the top dog ears  312 ,  314  of the second embodiment shown in  FIGS. 8 and 9  are splayed tabs serving as engaging features to prevent movement of the holder  300  in a frontward direction when the holder  300  is in its installed configuration on a chain link fence  50 , but are different therefrom in that the top dog ears  312 ,  314  of the second embodiment shown in  FIGS. 8 and 9  may generally be longer than the corresponding legs  102 ,  104  of the first embodiment shown in  FIGS. 1 through 5  so long as angle-in/angle-out installation is permitted thereby. As discussed above with reference to examples of the first embodiment employing splayed tabs as engaging features, to prevent play in the front-to-back direction it is preferred that the depths of the top shallow dog ear  312  and the top deep dog ear  314  relative to the back face of the base  320  be chosen so as to permit a more or less flush installed configuration when the holder  300  is installed on the chain link fence  50 . 
     The bottom shallow stop  317  of the second embodiment shown in  FIGS. 8 and 9  is similar to one of the shallow legs  102  of the first embodiment shown in  FIGS. 1 through 5 , and the bottom deep stop  319  of the second embodiment shown in  FIGS. 8 and 9  is similar to one of the deep legs  104  of the first embodiment shown in  FIGS. 1 through 5 , in that the bottom stops  317 ,  319  of the second embodiment shown in  FIGS. 8 and 9  respectively engage with wire in the shallow and deep planes of the chain link fence  50 , but are different therefrom in that the bottom stops  317 ,  319  of the second embodiment shown in  FIGS. 8 and 9  predominantly serve as engaging features to prevent movement of the holder  300  in a downward direction when the holder  300  is in its installed configuration on a chain link fence  50  but do not necessarily serve as engaging features to prevent movement of the holder  300  in the front-to-back direction when the holder  300  is in its installed configuration thereon. That is, as best seen at  FIG. 8 , the bottom stops  317 ,  319  in the embodiment shown do not have splayed tabs but instead project straight back, i.e., in perpendicular fashion, from the base  320 , the bottom stops  317 ,  319  merely resting on wire of the chain link fence  50  as weight from one or more objects suspended from the floor  330  and/or the roof  370  causes the bottom-facing surfaces of the bottom stops  317 ,  319  to contact the top-facing surfaces of the wire of the chain link fence  50 . 
     However, as a first variation on the second embodiment shown in  FIG. 8 , the bottom stops  317 ,  319  may have splayed tabs as engaging features to additionally prevent play in the frontward direction, in which case it is preferred that such splayed tabs be short enough not to interfere with angle-in/angle-out installation. 
     Alternatively, as a second variation on the second embodiment shown in  FIG. 8 , the bottom stops  317 ,  319  may be without splayed tabs as at the embodiment shown in  FIG. 8 , but unlike the embodiment shown in  FIG. 8  be of such shape and/or orientation as to each only contact the wire of the chain link fence  50  at substantially a single point. For example, in such a second variation on the second embodiment shown in  FIG. 8 , the bottom stops  317 ,  319  of the embodiment shown in  FIG. 8  may be replaced by pole-like projections protruding straight back, i.e., in perpendicular fashion, from the base  320 , or the bottom stops  317 ,  319  in such a second variation on the second embodiment shown in  FIG. 8  might alternatively be of size and shape as shown in  FIG. 8  but each be respectively rotated 90 degrees relative to the configuration shown in  FIG. 8  so that instead of abutting the wire of the chain link fence  50  side-on or in parallel fashion as in the embodiment shown in  FIG. 8 , the bottom stops  317 ,  319  abut the wire of the chain link fence  50  end-on or in perpendicular fashion. 
     Whereas the holders  100 ,  200 ,  300  of the first embodiment and variations thereon shown in  FIGS. 1 through 7  are designed for straight-in/straight-out installation or twist-in/twist-out installation, the holder  300  of the second embodiment shown in  FIGS. 8 and 9  is designed for angle-in/angle-out installation. That is, referring to  FIGS. 8 and 9 , to install the holder  300  of the second embodiment on a chain link fence  50 , the holder  300  would be held in horizontal fashion such that the floor  330  and the roof  370  are directed upward, the top dog ears  312 ,  314  would be inserted into the meshwork hole of the chain link fence  50 , the holder  300  would be rotated in the “pitch” direction in such fashion as to raise the top dog ears  312 ,  314  and lower the bottom stops  317 ,  319 , at which time the top dog ears  312 ,  314  would be made to slide behind the wire of the chain link fence  50 , and the back face of the base  320  would be pressed against the chain link fence  50  until the bottom stops  317 ,  319  come into position above the wire of the chain link fence  50 , following which the holder  300  would be lowered until the bottom stops  317 ,  319  come to rest against the wire of the chain link fence  50 . Removal would be the reverse of installation. 
     Note that the base  320  of the holder  300  in the second embodiment shown in  FIGS. 8 and 9  is longer than the base  120  of the holders  100 ,  700 ,  200  of the first embodiment and variations thereon shown in  FIGS. 1 through 7 . That is, the critical surfaces of the engaging features on the legs  102 ,  104  in the first embodiment and variations thereon shown in  FIGS. 1 through 7  are mutually separated by distances on the order of one times the nominal hole size of the chain link fence  50 . In the second embodiment shown in  FIGS. 8 and 9 , the critical surfaces of the engaging features on the top dog ears  312 ,  314  are mutually separated by distances on the order of one times the nominal hole size of the chain link fence  50 , and the critical surfaces of the engaging features on the bottom stops  317 ,  319  are mutually separated by distances on the order of one times the nominal hole size of the chain link fence  50 . However, in the second embodiment shown in  FIGS. 8 and 9 , the engaging features on the top dog ears  312 ,  314  are separated from the engaging features on the bottom stops  317 ,  319  by distances on the order of two times the nominal hole size of the chain link fence  50 . In other words, whereas the holders  100 ,  700 ,  200  of the first embodiment and variations thereon shown in  FIGS. 1 through 7  straddle a single hole of the chain link fence  50 , the holder  300  of the second embodiment shown in  FIGS. 8 and 9  straddles two holes of the chain link fence  50 , and one of skill in the art will appreciate that more than two holes can be straddled by holders in accordance with the present invention and that a great many similar variations are possible that allow flexibility in size and shape while still permitting the engaging features to engage with the wire of the chain link fence  50 . There is therefore no limitation regarding whether engagement of the wire of the chain link fence  50  by the respective engaging features in holders in accordance with the present invention occurs at the same hole or at different holes. Moreover, while there is no particular objection to employment of a longer base at the first embodiment or a shorter base at the second embodiment, the base is shown as longer in the second embodiment in  FIGS. 8 and 9  than in the first embodiment and variations thereon in  FIGS. 1 through 7  because such a longer base is thought to be preferred for designs employing angle-in/angle-out installation. 
     In the embodiment shown in  FIG. 8 , while there is no particular objection to employment of elastic materials, because angle-in/angle-out installation requires neither an inwardly sprung nor an outwardly sprung design, comparatively inelastic materials such as metal may be employed in the holder  300  of the second embodiment. Note, moreover, that the angle-in/angle-out installation permits a relatively flat profile for the holder  300 , facilitating storage and transportation. 
     At  FIG. 8 , dashed lines indicate possible variations on the structure shown in solid line. For example, the vertically elongated octagonal profile shown in dashed line indicates the outline of a faceplate that might replace the base  320  shown in solid line or that might be connected to and extend in a plane in front of the base  320  shown in solid line at  FIG. 8 . Furthermore, the curved profile shown in dashed line indicates the outline of a cuplike receptacle, in which drinks and the like can be placed, that might protrude toward the front from the base  320 . 
     Referring to  FIG. 10 , this shows a holder  400  in accordance with a third embodiment of the present invention. To the extent that the holder  400  in accordance with the third embodiment described with reference to  FIG. 10  is similar in structure and/or function to the holder  100  of the first embodiment described above with reference to  FIGS. 1 through 5 , like parts are given like-numbered reference numerals and description thereof is omitted for brevity. 
     At the holder  400  shown in  FIG. 10 , deformable elastic material  480  such as sponge rubber, thermoplastic or thermosetting resin foam, or solid or hollow rubber or rubber-like material is attached to a base  420 . The deformable elastic material  480  is of such dimensions and material properties as to allow it to be pressed into a meshwork hole in a chain link fence  50  and become lodged therein. Moreover, dimensions and material properties of the deformable elastic material  480  allow the holder  400  to be removed from the meshwork hole in the chain link fence  50  when pulled out therefrom. Although omitted for ease of description, any of a variety of suitable holding features for holding drinks or other objects such as those described with reference to  FIGS. 1 through 9  or  11  through  15  may be provided at the front of the base  420 . 
     Signage  500  in accordance with a fourth embodiment of the present invention is shown in  FIGS. 11 and 12 ,  FIG. 11  being a front view thereof and  FIG. 12  being a rear view thereof. To the extent that the signage  500  in accordance with the fourth embodiment described with reference to  FIGS. 11 and 12  is similar in structure and/or function to one or more of the holders described above, like parts are given like-numbered reference numerals and description thereof is omitted for brevity. In the fourth embodiment shown in  FIGS. 11 and 12 , a pair of shallow legs  502 ,  502  engage with wire in the shallow plane of the chain link fence  50 , and a pair of deep legs  504 ,  504  engage with wire in the deep plane of the chain link fence  50 . Attached at the front of the signage  500  of the fourth embodiment is a diamond-shaped base  520  on which a symbol  525  such as the letter “A” is depicted. While the letter “A” has been shown as an example, any such symbol, including any of a variety of letters and/or numerals, may be depicted on the base  520 . By inserting signage  500  depicting appropriate symbols  525  into the meshwork holes of a chain link fence  50  in a suitable pattern, it is possible to spell out or otherwise communicate an intended message. 
     Signage  600  in accordance with a fifth embodiment of the present invention is shown in  FIG. 13 .

       FIGS. 14 and 15  respectively show attachment plates  800 ,  900  in accordance with sixth and seventh embodiments of the present invention. To the extent that the attachment plates  800 ,  900  in accordance with the sixth and seventh embodiments respectively described with reference to  FIGS. 14 and 15  are similar in structure and/or function to one or more of the holders described above, like parts are given like-numbered reference numerals and description thereof is omitted for brevity. 
     At the front of the attachment plate  800  of the sixth embodiment shown in  FIG. 14  is a base bearing one component  885  of a hook-and-loop fastener system or other such two-component fastener system such as Velcro® (registered trademark of Velcro Industries B.V. of Manchester, N.H., USA). When the attachment plate  800  of the sixth embodiment is installed on a chain link fence  50 , the other component of such two-component fastener system may be conveniently attached thereto and removed therefrom as desired. 
     At the front of the attachment plate  900  of the seventh embodiment shown in  FIG. 15  is a base bearing a tiedown loop  990  to which any of a variety of fastening media such as tiewraps, rope, cord, wire, or the like may be tied or otherwise fastened. When the attachment plate  900  of the seventh embodiment is installed on a chain link fence  50 , one or more tiewraps or other such cable tie or other fastening media may be conveniently attached thereto and removed therefrom as desired. 
       FIGS. 16 and 17  respectively show a rear view and an angled view of an alternative implementation of the legs of the holder of  FIG. 1 . Under this implementation, the deep legs  104  are configured in an S-shaped fashion, so that the legs are attached to back face  110  at the center portion of the S. The engaging features  103  are attached at the ends of deep legs  104 . As depicted in  FIG. 17 , each engaging feature  103  is a groove having an upper and lower lip to engage a chain link wire. However, there is no objection to the engaging feature  103  being a single lip to engage a chain link wire. In this implementation, shallow legs  102  are proportionately shorter than deep legs  104 , and engaging features  101  are located on shallow legs  102 . As with engaging feature  103 , engaging feature  101  may be a groove or a single lip. In implementations where engaging feature  101  is a single lip, the back face  110  may work in cooperation with engaging feature  101  to engage a chain link wire. 
     The deep legs  104  attach to the back face  110  near where the top and bottom of the S meet in the center. The top and bottom ends of the S, where the engaging features  103  connect to deep legs  104 , float free from the back face  110 , allowing the engaging features  103  to flex inward toward the center of the back face  110 . This flexibility may allow the S-shaped configuration of  FIGS. 16 and 17  to facilitate both snap-in/snap-out and twist-in/twist-out installation of the holder with a chain link fence, as discussed earlier. While this arrangement of the legs has been discussed in connection with holder embodiments, it should be understood that this arrangement is also applicable to other embodiments, such as signage ( FIG. 11 ), hook and loop ( FIG. 14 ) and clips ( FIG. 15 ). 
       FIG. 18  collectively shows a front view,  FIG. 18A , a side view,  FIG. 18B , and a top view,  FIG. 18C , of an eighth embodiment of the present invention. Please note that where possible similar elements retain their numbers from earlier embodiments. The eighth embodiment provides a holder  1800  with a clasp system with a female member  1810  and a male member  1820 . The female member  1810  is attached to a back face  110  of a base  120 . The base  120  attaches to a chain link fence  50 , in a similar fashion to previous embodiments, such as shown in  FIGS. 16 and 17 , with legs  102 ,  104  and engaging features  101 ,  103 . As shown in  FIG. 18 , the female member  1810  and the male member  1820  may cooperate as a sliding tongue-and-groove mechanism, where the female member  1810  may be a slot  1815  with a U-shaped base  1817  when viewed from the front, and where the male member  1820  is a peg with a T-shaped profile when viewed from the top. The female member  1820  receives the male member  1810  in the top of the slot  1815 , and the male member  1820  slides down the slot  1815  until coming to rest at the U-shaped base  1817 . 
     The clasp system male member  1820  is attached to an accessory attachment  1850 . The clasp system allows a single holder  1800  support several interchangeable accessory attachments  1850 . The accessory attachment  1850  may be, among other things, a beverage holder, a hook, a utility shelf, or a basket. 
     While  FIG. 18  depicts the clasp system with female member  1810  and male member  1820  arranged as a sliding tongue-and-groove mechanism, a person having ordinary skill in the art will recognize that many variations of a clasp system are possible within the scope of this invention, such as a snap joint, a dovetail joint, or a friction mount. Similarly, while the clasp system in  FIG. 18  depicts the female member  1810  attached to base  120  and the male member  1820  attached to the accessory attachment  1850 , this does not limit implementations where the male member is attached to the base and the female member is attached to the accessory attachment, or other clasping arrangements. 
     Although the present invention has been described in terms of examples in which the invention is applied to holders such as drink holders, signage, and attachment plates, the present invention is not limited thereto, it being possible to apply the gripping portion of the holder to all manner of holders for holding any of a wide variety of objects to a chain link fence. 
     Furthermore, although description of the present invention herein includes examples in which legs project more or less straight back, i.e., in perpendicular fashion, from a base of a holder, it may be preferred for compactness of design and/or ease of installation in some embodiments that the legs, e.g., in the outwardly sprung design described above, respectively make an angle of less than 90 degrees with the back face of the base so as to taper inward distally such that the leg ends approach an axis drawn perpendicularly rearward from a central point on the back face of the base of the holder when the holder is in its uninstalled configuration and the legs are in their undeflected state. 
     Moreover, although the present invention has been described in terms of an example in which a holder is attached to a chain link fence made up of 9 gauge (approximate diameter 0.15 inch) wire interwoven to form diamond-shaped holes that are 2 inches on a side, with an approximate difference of 0.5 inch between shallow and deep planes, the present invention is not limited thereto, it being possible to apply the invention to any of a wide variety of chain link fences, with appropriate modification to the dimensions of the holder. 
     As described above, holders in accordance with various embodiments of the present invention solve one or more of the problems mentioned above, and may also provide other advantages and benefits. 
     It should be emphasized that the above-described embodiments of the present invention are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described embodiments of the invention without departing substantially from the spirit and principles of the invention.
