The present application claims priority back to the date of the filing of the application listed below which is hereby incorporated herein by reference in its entirety: 
         [0002]    Provisional patent application having Ser. No. 61/912,313 filed on Dec. 5, 2013. 
     
    
     TECHNICAL FIELD 
       [0003]    The present invention is generally directed to bicycling. More particularly, the present invention is directed to a shelf device designed for assisting in the wall mountable storage of a bicycle. Even more particularly, the present invention is directed to a device as previously described which further includes an opening into which a bicycle rider may place a riding helmet. 
       BACKGROUND OF THE INVENTION 
       [0004]    Whether regarded as sport, exercise or transportation, the utilization of bicycles and the popularity of their use has grown significantly. There are many reasons for this growth including advances in bicycle technology, the recognition of the desirability of exercise, the characterization of cycling as an energy efficient means of transportation and the geographics of an urban environment in which cycling distances are sufficiently short, thus providing advantages over other forms of urban transportation. Although it is not unique to the urban environment, urban areas do provide challenges to those deciding to engage in cycling. Additionally, apartments and other dwellings in urban environments tend to have limited storage capacity. Such limitations are consonant with higher population densities found within cities and similar metropolitan areas. Furthermore, the physical dimensions of cycling vehicles render it extremely difficult, if not impossible, to sometimes provide adequate storage for bicycles especially since they are poorly sized for storage in a closet. 
         [0005]    The present invention is also usable in commercial environments such as bicycle shops and other retail and wholesale environs where bicycles are either sold or displayed, such as at a trade show. In such environs, the present invention has the advantage of displaying many bicycles in a small area (lower retail footprint). It also provides easy access for dismounting bicycles for ease of demonstration and closer viewing. 
         [0006]    Conventional storage of bicycles on walls is done by hooking them by the top tube of the bicycle frame or by their wheels to a shelf, hook or bracket. Hanging of a bicycle for storage by its upper tube frame is not, however, a very practical solution for bicycles designed for female riders. Additionally, it is noted that bicycle storage which employs mechanisms in which they are hung upside down by their wheels requires a clumsy lifting and inverting effort before it can be hung. 
         [0007]    It is also to be particularly noted that many state, county and other municipal jurisdictions, in an effort to promote safety for those engaged in cycling, have passed laws, regulations and ordinances requiring cyclists to wear protective head gear. Even in locales where the wearing of helmets is not mandatory, cyclists still often opt for the use of a helmet for their own safety and protection. Accordingly, those engaged in cycling typically return to their abodes with a need to store both their bicycles and their helmets. The present invention provides a structure providing both of these functions in a single device. 
         [0008]    From the above, it is therefore seen that there exists a need in the art to overcome the deficiencies and limitations described herein and above. 
       SUMMARY OF THE INVENTION 
       [0009]    The shortcomings of the prior art are overcome and additional advantages are provided by a device for holding a bicycle which has a seat. The device of the present invention comprises a block of material having an opening on one face thereof which is sized for helmet storage. The block also includes an upwardly extending portion which holds the bicycle by its seat. In one embodiment of the invention there is further provided a safety ridge on the front portion to more readily keep a mounted bicycle from falling. 
         [0010]    The block of the present invention may comprise any convenient material including wood, plastic and metal. However, plastic materials constitute a preferred composition in that they are lightweight, readily molded and durable. Additionally, it is noted that the present invention may be provided in both left and right-handed versions. 
         [0011]    Accordingly, it is an object of the present invention to provide a rack for the easy storage of a bicycle. 
         [0012]    It is another object of the present invention to promote the use of bicycles, particularly in urban locations. 
         [0013]    It is yet another object of the present invention to provide a bicycle rack which is easily manufactured. 
         [0014]    It is a still further object of the present invention to provide a bicycle rack that constitutes an integral structure. 
         [0015]    It is still another object of the present invention to provide a plurality of racks for holding bicycles in an area characterized as having a small footprint. 
         [0016]    It is another object of the present invention to provide a device for storing bicycles used by both male and female riders. 
         [0017]    Lastly, but not limited hereto, it is an even further object of the present invention to provide a bicycle rack which is easily mountable on a wall. 
         [0018]    Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. It is also noted that the terms “rack” and “shelf,” as used herein to describe the present invention, are used interchangeably. 
         [0019]    The recitation herein of desirable objects which are met by various embodiments of the present invention is not meant to imply or suggest that any or all of these objects are present as essential features, either individually or collectively, in the most general embodiment of the present invention or in any of its more specific embodiments.

     DETAILED DESCRIPTION 
       [0037]      FIG. 1  is illustrative of one embodiment of the present invention. The rack of the present invention preferably comprises an integral structure formed from a single piece of material, as for example, from a mold. The rack includes an upwardly extending portion  8  which is shaped to hold a bicycle by its seat. It is noted that bicycle seats are, for all practical purposes, a universal feature of all bicycles a fact which makes the present invention universally usable to the same extent. 
         [0038]    Another significant feature of the present invention is the presence of an aperture which is formed within the main portion of the integral structure. In the embodiment shown in  FIG. 1 , this aperture is bounded at least by bottom portion  12  and upper portion  10  of the integral structure. It is noted that upper portion  10  does not constitute an essential feature of the present invention, although in is preferred and assists in providing rigidity. The aperture seen in  FIG. 1  and in other illustrations of the present invention is preferably sized to accommodate the insertion of a bicycle helmet. Thus, the present invention provides a rider with easy access both to his/her bicycle but to a highly desirable, if not mandated, article of safety equipment. While the aperture is preferably sized to fit a bicycle helmet, it is noted that the aperture may be sized to accommodate any cycling or other accessory such as, but not limited to, hats, scarves, goggles and gloves. 
         [0039]    In order to provide a degree of protection against a situation in which a mounted bicycle could fall off the shelf, there is provided raised safety ridge  9  which extends upwardly from the from face of the device near seat hook  8 . 
         [0040]    Also shown in  FIG. 1  is back wall  2  of the rack. It is also noted that back wall  2  is not an essential feature of the present invention. It is preferably provided to insure a desired degree of rigidity and strength. Wall  2  is also very useful for purposes of mounting the shelf on a wall, as is more particularly described below in  FIGS. 9 and 10 . Its presence is also consistent with molding processes that are employed in shelf manufacture. Such processes are also advantageous in that color options are more readily available, such as by changing material input to the mold without the necessity of changing the mold. 
         [0041]      FIG. 2  illustrates the present invention in its ordinary use with a bicycle suspended from it. In particular, there is shown bicycle seat  4  hooked over upwardly extending seat hook  8 . In conventional bicycle storage systems, the bicycle is suspended from top tube  14  of its frame, at least for bicycles intended for male riders. Bicycles used by female riders are typically stored from ceiling mounted hooks which are used to suspend a bicycle by one or more of its wheels.  FIG. 6  also illustrates the ordinary and customary use of the present invention with a bicycle hung from it. As above, bicycle seat  4  is seen hooked over seat hook  8 . Top bicycle tube  14  and wheels  16  of the bicycle are also visible in this figure.  FIG. 7  is similar to  FIG. 6  except that it illustrates an alternate shape that is employed to embody hook  8 . Likewise,  FIG. 8  illustrates an alternate embodiment for the shape of the rack. Furthermore, in this regard, it is to be noted that the present invention may be embodied in a variety of shapes, some even fanciful, if desired. 
         [0042]      FIG. 3  illustrates an embodiment of the present invention in which upwardly extending seat hook  8  is disposed on the right side of the unit.  FIG. 4  is a view similar to that shown in  FIG. 3  except from a perspective which better illustrates the presence of raised safety edge  9 . Again,  FIG. 5  provides yet another view of the rack of the present invention from a somewhat different view so as to enhance the clarity and understanding of its structure. Reference numerals shown in the Figures herein are used to refer to the same items as shown and as found in the list of items below. 
         [0043]    As indicated above, the present invention is easily mounted on a wall or other surface. For this purpose, one may employ nails, screws or molly bolts. If it is truly “super” strength in nature, adhesives are also employable, though not preferred.  FIG. 9  illustrates the use of nails  22  for affixation of the rack to wall  20 , typically an interior wall, though clearly not limited thereto. Nail or screw openings are providable beforehand in a finished product via a molding process, if that is the route of manufacture selected. In an alternate method of affixation, mounting cleat  24 , for wall installation, is shown affixed to wall  20  via nail (only one nail visible)  22 . Screws or other anchoring means may also be employed with cleat  24 . Cleat  24  includes an upwardly angled portion, as shown, intended to mate with a correspondingly shaped portion  26  on back  2  of the rack. See  FIG. 10 . 
         [0044]      FIGS. 11, 12 and 13 , as described above are included to provide further views of the present invention from different perspectives so as to enhance the clarity of understanding. As above, reference numerals shown therein are used to refer to the same items as shown and discussed above. 
         [0045]      FIGS. 14, 15 and 16  depict an alternate embodiment of the present invention from three different perspective views in which support of bicycle seat  4  is provided by rod  28 . Rod  28  is attachable to the shelf in several different ways. Firstly, rod  28  may comprise a spring loaded dowel that urges its ends into openings in the shelf. This is a well-known structure ubiquitously found in toilet paper dispensers. Secondly, rod  28  may comprise an integral dowel structure which is dropped down into slots (not shown in the embodiment of  FIG. 14-16 ) in the main shelf structure. Thirdly, rod  28  may comprise a molded-in cylinder extending from one arm of upwardly extending “horn” portions to an opposite arm. Note that here, the word “cylindrical” is not limited to objects having circular cross-sections. Here, any convenient cross-section is employable including, but not limited to elliptical, rectangular, square or triangular cross-sections.
