BACKGROUND 
       [0001]    The present disclosure pertains generally to adjustable merchandising systems for shelving. More specifically, the present disclosure pertains to an easy to install front fence for an adjustable merchandiser used on shelving. The merchandiser can be removably attached to an associated shelf and is configured to organize merchandise on the shelf. 
         [0002]    Shelving is used extensively for stocking and storing products or merchandise in a variety of stores. For a number of important merchandising considerations, it is desirable that merchandise be displayed at the front of a shelf so that a customer is induced to purchase the article. For example if the goods are perishable or are subject to becoming stale (e.g., cigarettes, fruit juices, dairy products or any item with an expiration date or a freshness date), it is important that the articles be removed in a first in, first out basis in order to maintain freshness. Also, if merchandise is not displayed at the front of the shelf, it may not catch the shopper&#39;s eye which may cost the merchant sales. 
         [0003]    In order to automatically move an item forward on a shelf as the one before it is removed, several types of forward feed devices have been devised. These devices generally fall into three categories. The first category is inclined tracks. These rely on gravity to feed, slide or roll products forward. The second category employs conveyor belts which still use gravity to effect a forward movement. The third category uses spring biased paddles to feed the product forward. Whichever forward feed mechanism is employed, it is necessary that the front of the shelf be provided with a barrier or fence, so that the merchandise urged forward does not fall off the shelf. 
         [0004]    The current front fences or front rails are disadvantageous from the standpoint that separate fasteners are required in order to secure the front rail or fence to the shelf. Accordingly, it has been considered desirable to develop a new and improved front rail which would overcome the foregoing difficulties and others, while providing better and more advantageous overall results. 
       BRIEF SUMMARY OF THE DISCLOSURE 
       [0005]    In accordance with the present disclosure, a new and improved front rail is provided. In one embodiment, the front rail includes a set of spaced fasteners integral with a body of the front rail. The fasteners cooperate with apertures provided in an associated subjacent shelf to which the front rail is selectively secured. The fasteners can be resilient so as to allow the front rail to be readily secured to or removed from the associated subjacent shelf. 
         [0006]    In one embodiment, a merchandising system includes a front rail and at least one fastener element of one piece with the front rail and adapted to selectively connect the front rail to an associated subjacent shelf. The fastener element can comprise a snap protrusion. The fastener element can include a first portion, a second portion and a gap defined between the first portion and the second portion. At least one of the first and second portions can include a distal portion comprising a tapered side wall, a central portion and a proximal portion. The proximal portion can include a tapered side wall. The tapered side wall of the distal portion tapers towards an end face of the at least one of the first and second portions. The tapered side wall of the proximal portion tapers towards a bottom surface of the front rail. 
         [0007]    In another embodiment, the fastener element can comprise a generally cylindrical member which includes a hollow central area. In a further embodiment, the fastener element can comprise at least one groove or channel which is defined in an outer surface of the fastener element. The groove or channel can extend generally along a longitudinal axis of the fastener element. 
         [0008]    The front rail can include a top surface and a bottom surface and the at least one fastener element can protrude from the bottom surface. A plurality of spaced fastener elements can protrude from the bottom surface. The plurality of spaced fastener elements can be selectively inserted into apertures defined in the associated subjacent shelf. The system can further comprise a divider selectively connected to the front rail. Further, the system can comprise a pusher assembly selectively connected to the front rail.

     DETAILED DESCRIPTION 
       [0019]    Referring now to the drawings wherein the showings are for purposes of illustrating several embodiments of the present disclosure and not for purposes of limiting same,  FIG. 1  shows a prior art merchandising system. This includes a front rail  14  which is selectively secured to a subjacent shelf (see  FIG. 2 ) via a set of separate fasteners  16 . It is noted that the fasteners are separate elements and need to be manually installed in suitable apertures (not illustrated) in the front rail in order to secure the front rail to a subjacent shelf. When a barrier or transparent lens is connected to the front rail (by being positioned in a longitudinally extending groove defined in the front rail) it is sometimes called a front fence. Mounted to the front rail is a product feed system  20 . In the embodiment illustrated, the product feed system includes a left end wall  22 , a track  24  on which is mounted a pusher  26 , for urging a column of product forward towards the front end of a shelf, and a divider  28 . It should be appreciated that any number of tracks and dividers can be employed, depending upon the number of columns of merchandise which are meant to be vended on a particular shelf. Moreover, it is also known to have an integrated pusher and divider assembly and such a structure can also be selectively secured to the front rail  14 . A right end wall  30  is mounted opposite the left end wall  22 , thus defining the product feed system  20  on the shelf. 
         [0020]    One disadvantage of the front rail  14  illustrated in  FIG. 1  is that separate fasteners  16  need to be employed in order to selectively connect the front rail to a subjacent shelf. Thus, packaged together with the front rail, or at least accessible to the person at the store installing the front rail, needs to be a set of fasteners  16  so that the front rail can be connected to a shelf. As might be appreciated, the fasteners are small and are easily lost during the installation process, thus leading to wastage. More importantly, the amount of labor involved in installing the fasteners to connect the front rail to a shelf is not insignificant. Therefore, the installation process can be costly, both from a man power and a parts standpoint. 
         [0021]    According to the present disclosure, an improved front rail is provided in which the fasteners that secure the front rail to the subjacent shelf are of one piece with or integral with the body of the front rail. One such embodiment is illustrated in  FIG. 2 . In this embodiment, the front rail is generally L-shaped and includes a horizontal section  42  and a vertical section  44 . Selectively mounted in the vertical section is a front fence  46  which is generally made of a transparent material so that the product being sold on the shelf is clearly visible. Extending from a bottom face of the front rail  40  is a set of fasteners  50 , which are integral with the front rail. The fasteners  50  are so spaced and sized as to allow the front rail to be connectable to a subjacent shelf. In one embodiment, a shelf  54  includes a top surface  56  in which are defined a plurality of spaced apertures  58 . The fasteners  50  are capable of being inserted into the apertures  58  as is illustrated by arrows  60 . 
         [0022]    With reference now to  FIG. 3 , another embodiment of a front rail  70  is there illustrated. In this embodiment, the front rail includes a bottom wall  72  on which are located a plurality of spaced fasteners  74 . With reference now to  FIG. 4 , in one embodiment, the fasteners  74  can comprise a first section  78  and a second section  80  with the two sections being separated from one another by a slot  82 . It should be appreciated that the fasteners  74  protrude away from the bottom wall  72  in a direction approximately normal to a plane of the bottom wall  72 . 
         [0023]    Generally speaking, the front rail is made of a suitable conventional thermoplastic material and so, too, are the fasteners  74  which, as mentioned, are of one piece with the material of the front rail. Due to the inherent resiliency of such thermoplastic material, and the presence of the slot  82 , the fastener can flex radially so as to be capable of entering an aperture in the shelf and then flexing outwardly so as to snap into place and lock the front rail to the shelf in a resilient manner. In one embodiment, the front rail is molded of a conventional thermoplastic material such that the fasteners  74  are molded together with the front rail  70 , thus forming a one-piece unitary product. Due to the inherent resiliency of the fasteners  74 , the front rail  70  can also be removed from the shelf as may be required in certain circumstances. 
         [0024]    With reference now to  FIG. 5 , a top perspective view of another front rail is there illustrated. The front rail includes a horizontal section  90  and a vertical section  92  in which is defined a longitudinally extending slot  94 . As may be recognized, the slot  94  is employed to hold a front fence.  FIG. 6  is an enlarged front plan view of the front rail of  FIG. 5 . It illustrates integral fasteners  100  which extend from a bottom face  102  of the front rail. With reference now to  FIG. 7 , the fasteners can each include a first section  110  which is separated from the second section  112  by a slot  114 . It should be appreciated from  FIG. 7  that the fasteners are tapered so as to have a tapered distal end  116  leading to an enlarged central portion  118  and a somewhat tapered or reduced diameter proximal end  120 . Thus, each of the two fastener sections  110  and  112  have a tapered distal section, an enlarged central portion and a somewhat reduced diameter proximal section. This configuration of the fastener allows the fastener to readily enter the apertures in the shelf, snap into place, and be generally securely positioned in the aperture so as to retard the removal of the front rail from the shelf holding it. However, due to the inherent resiliency of the thermoplastic material from which the fastener is made, the front rail can be peeled away from its support shelf by pulling upwardly on one end of the front rail and thereby serially disengaging each of the fasteners  100  from the apertures in the shelf on which the front rail was mounted. 
         [0025]    With reference now to  FIG. 8 , a side elevational cross-sectional view of another front rail according to the present disclosure is there illustrated. The front rail  130  includes a horizontal section  132  and a vertical section  134  in which is defined a longitudinally extending slot  136 . Depending from a bottom face  140  of the front rail  130  is a fastener  150 . It can be seen that the fastener includes a hollow central section  152 . This enhances the resiliency of the fastener  150  as the front rail  130  is made from a suitable thermoplastic or like resilient material. With reference now to  FIG. 9 , an outer surface of the fastener  150  can include one or more indented portions, grooves or channels  154 . These serve to further increase the resiliency of the fastener and enable it to snap more easily into corresponding apertures in the shelf to which the front rail is selectively secured via the fasteners. In the embodiment illustrated in  FIG. 9 , four such slots or grooves  154  are defined. It can be appreciated that each of these extends generally vertically from a bottom face  156  of the fastener upwardly towards the bottom surface  140  of the front rail. 
         [0026]    It should be appreciated that there are several different shelving manufacturers producing shelving for grocery stores, drug stores, hardware stores and the like. The different manufacturers produce shelving where the spacing between adjacent apertures in the shelving varies from one manufacturer to another. Therefore, it is contemplated that a plurality of front rails would be provided with snap protrusions located in specific positions to accommodate the aperture spacing of each of the several shelf manufacturers. 
         [0027]    One advantage of the present disclosure is a new and improved shelf management system, including a front rail which can be readily mounted to and detached from a support shelf without the use of separately providing fasteners. Another advantage of the present disclosure is that it dispenses with the need for using separate fasteners which are physically disconnected from the front rail and are, thus, easily lost and more time consuming (and expensive) to install or remove. 
         [0028]    The disclosure has been described with reference to several embodiments. Obviously, modification and alterations will occur to others upon a reading and understanding of this specification. It is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims and the equivalents thereof.
A merchandising system includes a front rail which is adapted to be selectively mounted to an associated shelf. The front rail includes a fastener element which is of one piece with the front rail. The fastener element selectively secures the front rail to the associated shelf.
