DETAILED DESCRIPTION OF THE INVENTION

(22) Turning now to the drawings, the same illustrate an embodiment of a shelving system according to the teachings herein. As will be understood from the following, the shelving system provides several advantages over existing designs. First, it utilizes an upper rail and a lower rail which are separately mountable from one another. A number of upright supports are slidably received by these upper and lower rails. As a result, an installer can easily mount the upper rail, then mount the lower rail, and then slide the upright supports into the rails. This is a distinct departure from prior designs which employ a grid structure that is welded together as a one piece unit.

(23) Second, the shelving system according to the teachings herein utilizes shelves which may be assembled onto the upright supports once they are installed. This is a distinct advantage over prior designs which require lifting a shelf as a unit onto a grid structure. Instead, according to the teachings herein, the shelf is rapidly assembled piece by piece in place. As a result, relatively light parts are lifted during installation, which are also far less cumbersome. Third, the shelf or shelves of the current application utilize plastic deck panels which may be formed of a NSF compliant material. Fourth, because both the rails, the upright supports, and shelf or shelves are designed to be assembled during installation, they may be shipped in a much smaller container than in prior designs. Fifth, due to the size and modular nature of the deck panels, these panels may be easily removed for cleaning in a sink or dishwasher. This is a distinct advantage over prior designs, which require removing the entirety of the shelf as a single unit and washing the same in a cleaning area which accommodates cleaning of relatively large objects. These and other advantages will become more apparent from the disclosure herein.

(24) With specific reference now to FIG. 1, the same illustrates an exemplary embodiment of a shelving system 100 according to the teachings herein. Shelving system 100 includes a grid assembly with one or more shelves 108 mounted thereto. While one shelf 108 is shown, it is contemplated that any number of shelves may be mounted to this grid assembly. Further, while shelf 108 illustrated the full length of the grid assembly, shorter shelf lengths are entirely possible due to the highly customizable nature of the grid assembly and through the use of a common and modular deck panel as discussed below.

(25) The grid assembly itself consists of a number of separate and distinct components which will be discussed in turn. As mentioned above, this approach of having separate components has a distinct advantage over grid structures of prior designs which are a welded structure which is relatively large and cumbersome.

(26) The grid assembly includes an upper rail 102 and a separate lower rail 104. Upper and lower rails 102, 104 are configured to mount to a support structure such as a vertical wall, the interior of a refrigerated or freezer case, etc. Indeed, upper and lower rails 102, 104 may be adapted to mount to any structure capable of supporting the same. As such, upper and lower rails 102, 104 may incorporate any mounting expedient.

(27) One advantageous feature of upper and lower rails 102, 104 is that they are separate components. As a result, they may be separately installed to the aforementioned support structure. This makes installation considerably easier than in prior designs which require lifting a large welded grid structure as a single unit and installing it in place on a support structure.

(28) A plurality of upright supports 106a, 106b, 106c are slidably received in upper and lower rails 102, 104. As will be explained below, rails 106a-c are used for mounting shelf 108 thereto. It should be noted that three upright supports 106a-c are illustrated for purposes of description. However, only the outer most upright supports 106a, 106c are needed for mounting the illustrated shelf 108. Multiple additional shelves 108 may mount to the same two upright supports 106a, 106c below shelf 108 as illustrated. Further, shelves 108 having a shorter length may be mounted between upright supports 106a and 106b, or between upright supports 106b and 106c. Unless otherwise specifically noted herein, any description of the structure, function, or use of one upright support 106a-c applies equally to the others.

(29) One advantage having separate upright supports 106a-c is the ability to add or remove a desired number of upright supports as discussed below to allow for a specific shelving configuration. This is a distinct departure from prior welded designs as discussed above. In such welded designs, a fixed number of upright supports are provided, making customization difficult. The number of upright supports which may be included in the current application will be entirely dependent upon the shelving configuration desired. Therefore, the three upright supports 106a-c should be taken as only one of many possible examples. While two rails 102, 104 are shown and described, it is contemplated that only a single upper rail 102 could be utilized for receiving and supporting upright supports 106a-c.

(30) Turning now to FIG. 2, once upper and lower rails 102, 104 are installed, each upright support 106a-c is installed by generally situating the upright supports 106a-c into upper and lower rails 102, 104 by moving them generally in direction 110, and then sliding them in direction 112 to their final destinations. Upper and lower rails 102, 104 are designed such that they each include a channel within which the end portions of the upright supports 106a-c are situated and slidable in.

(31) Indeed, referring specifically to upright support 106a shown in FIG. 2, the same includes an upper end 114 and a lower end 116. A plurality of apertures 118 are formed therein for shelf mounting. These apertures 118 may take on any shape. An identical description to that of upright support 106a applies to 106c. Upright support 106c differs only in that it include two parallel rows of apertures 118 as illustrated.

(32) Turning now to FIG. 3, the same illustrates upper rail 102. Upper rail 102 includes a rail section 120 with a pair of identical mounting brackets 122a, 122b at opposed ends of rail section 120. Rail section 120 includes a channel 124 within which the upper end 114 of each upright support 106a-c is slidable. Further, rail section 120 also includes a mounting shelf 126 upon which each upright support 106a-c mates. This configuration ensures that upright supports 106a-c are at a uniform height relative to one another so that the apertures 118 horizontally align.

(33) Rail section 120 includes a lip 128 which depends downwardly from an upper wall 130 of rail section 120. This lip 128, upper wall 130, and mounting shelf 126 bound channel 124. The particular length of upper rail 102 shown should be taken by way of example only. Indeed, the length of upper rail 102 may be varied depending upon the desired sizing of shelving system 100.

(34) Turning now to FIG. 4, the same illustrates lower rail 104. Lower rail 104 also includes a rail section 140. The same pair of identical mounting brackets 122a, 122b used in upper rail 102 (see FIG. 3) are also used in lower rail 104 as shown. Rail section 140 also includes a channel 144 within which the lower end 116 of each upright support 106a-c is slidable. An opening 146 is formed in rail section 140. This opening 146 allows passage of lower end 116 (see FIG. 2) of each upright support 106a-c from an exterior of rail section 140 into channel 144 as discussed below.

(35) Rail section 140 includes a lip 148 which depends upwardly relative to a lower wall 150 of rail section 140. This lip 148 and lower wall 150 bound channel 144. The particular length of lower rail 104 shown should be taken by way of example only. Indeed, the length of lower rail 104 may be varied depending upon the desired sizing of shelving system 100. Further, lip 148 retains lower end 116 of upright supports 106a-c when situated in channel 144, preventing them from rocking away from a support structure upon which rails 102, 104 are mounted.

(36) Turning now to FIG. 5, the same illustrates a cross section in the region of the upper end 114 of upright support 106b when it is situated within channel 124. As may be seen in this view, upper end 114 closely resembles the shape of channel 124 to minimize relative movement between these structures. As may also be seen in this view, upright supports 106a-c each include a channel 152 which receives mounting shelf 126 as shown.

(37) Likewise, and as is shown in FIG. 6, lower end 116 closely resembles the shape of channel 144 to minimize relative movement between these structures. Lower end 144 may rest on bottom wall 150 as shown, or it may be spaced away from bottom wall 150. Indeed, the support provided by mounting shelf 126 (see FIG. 5) is sufficient to allow upright supports 106a-c to hang freely therefrom.

(38) FIGS. 7 and 8 illustrate a typical installation operation of uprights supports 106a-c. As shown in FIG. 7, upright support 106a is brought into proximity with upper rail 102 and angled as shown. Upright support 106a is then moved in linear direction 154 as shown until upper end 114 is partially situated within channel 124. Thereafter, and referring now to FIG. 8, upper rail is then rotated about its upper end 114 to pivot lower end 116 in direction 156 as shown. Doing so causes lower end 116 to pass through aperture 146 in rail section 140 of lower rail 104. This operation ultimately places lower end within channel 144. Once within channels 124, 144, upright support 106a may be slid in directions 160, 162 to its desired location. A successive operation as described above is undertaken for each upright support installed in upper and lower rails 102, 104. It is also contemplated that the above process could be reversed relative to upper and lower rails 102, 104. Indeed, upright supports 106a-c could be installed into lower rail 104 first in the same manner as they are installed into upper rail 102 described above, and then installed into upper rail 102 in the same manner as they are installed into lower rail as described above. It is thus contemplated that the structure and function of upper and lower rails 102, 104 could be swapped.

(39) Turning now to FIG. 9, the same illustrates an exemplary view of mounting bracket 122b. As noted above, mounting bracket 122b is identical to mounting bracket 122a. Mounting bracket 122b includes a movable plate 164 providing mounting features 168 for mounting to a support structure, and a fixed plate 166. Fixed plate 166 is fixed to its associated rail section 120, 140, while movable plate 164 is slidable relative to fixed plate 166. Movable plate 164 includes a pin 170 which is received in a slot 172 of fixed plate 166.

(40) Turning now to FIG. 10, this pin and slot configuration defines the amount of lateral travel movable plate 164 may undergo relative to fixed plate 166 before movable plate 164 is effectively separated from fixed plate 166. As an example in FIG. 10, movable plate 164 has moved in direction 174 relative to fixed plate 166. Such a slidable configuration allows the mounting brackets 122a, 122b to accommodate for deviations in corresponding mounting holes in a support structure arranged to receive mounting features 168. With momentary reference to FIG. 11, pin 170 attached to movable plate 164 via a leave spring 176 which may be deflected to such an extent to allow for full separation of movable plate 164 from fixed plate 166.

(41) Turning now to FIGS. 12-19, the same illustrate shelf 108 in greater detail. With particular reference to FIG. 12, shelf 108 includes a plurality of identical deck panels 180a, 180b, 180c, 180d. Given that deck panels 180a-d are identical, a description of any of one of said deck panels 180a-d applies equally well to the others. Although four deck panels 180a-d are shown to accommodate for the full length of shelf 108 illustrated, shorter shelves 108 will have fewer deck panels. For example, a shelf 108 half as long as that illustrated in FIG. 12 would only have two deck panels. Further, it is also contemplated that a shelf 108 may include a single deck panel. As will be discussed below, where multiple deck panels 180a-d are utilized, adjacent deck panels interlock with one another to prevent lateral movement of these deck panels 180a-d relative to one another. As one non-limiting example, each deck panel 180a-d may be one foot wide. A four foot long shelf would thus employ four deck panels. Although illustrated as mounting the grid assembly discussed above relative to FIGS. 1-11, it is contemplated that shelf 108 may be configured to mount to any existing structure by minor modification of the structure it utilizes for mounting. More generally, it is contemplated by the teachings herein, that the invention may be embodied as a combined system as reflected in FIG. 1 for example, or as a stand alone shelf 108 that may be retrofit into an existing system.

(42) Each deck panel 180a-d includes an upper surface 210 which is used to support merchandise. Further, deck panels 180a-d may include perforations as shown, or any other features typical of retail shelving, e.g. features for mounting a front fence 186 as shown, features for mounting dividers (not shown), a price channel or price channel support 232 (see FIG. 17), channels or other features for receiving and retaining lighting elements, etc. Deck panels 180a-d may be formed of a plastic material, for example, an acrylonitrile butadiene styrene (ABS) plastic. Such a material selection allows for the use of NSF certified materials for contacting retail items such as produce or the like.

(43) Further, because deck panels 180a-d are separable and removable from the remainder of shelf 108, they may be easily cleaned in a dishwasher, sink, etc. Further, although illustrated as forming a portion of a flat shelf, deck panels 180a-d may take on other forms. For example, deck panels 180a-d may be embodied as bins or any other expedient typically used in the retail environment for containing merchandise. Yet further, although not illustrated, pusher systems and other front facing devices may be readily mounted to deck panels 180a-d.

(44) Still referring to FIG. 12, in addition to deck panels 180a-d, shelf 108 includes first and second support arms 182 arranged at opposed sides of shelf 108. Support arms 182 are mirror images of one another, so a description of one applies equally well to the other. Shelf 108 also includes front and rear support bars 184 which are also identical to one another.

(45) Turning now to FIG. 13, shelf 108 is rapidly installable to the above described grid assembly by the following general process. First, each support arm 182 is mounted to a respective upright support 106a-c. In the illustrated embodiment the left-most support arm 182 is mounted to upright support 106a, and the right-most support arm 182 is mounted to upright support 106c. Thereafter, each support bar is 184 is installed by moving the same generally in direction 190 until a support post 188 of each support arm 182 is situated within a channel of each support bar 164 as discussed below. Once support bars 184 are in place, each deck panel 180a-d is then successively affixed in place to support bars 184 as discussed below.

(46) Alternatively, where support bars 184 are closed profile tubular elements, it is also contemplated that each support bar 184 is installed by horizontally sliding it onto the mounting post 188 of each support arm 182. Such an operation may be done prior to installing support arms 182 onto their associated upright support. Further, although a front and rear support bar 184 are shown, it is contemplated that for deeper shelf lengths, additional support bars 184 intermediate of front and rear support bars 184 could be utilized as well. Likewise, it is also contemplated that shallower shelf depths may only require a single support bar 184. As such, it is contemplated that at least one support bar 184 may be utilized for supporting the deck panel or panels 180a-d of shelf 108.

(47) Still further, although shelf 108 is described as mounting to two separate upright supports 106a, 106c, it is contemplated that shelf 108 may mount to a single upright support. Such a single upright support may be wider than those shown to accommodate mounting multiple support arms 182. For example, shelf 108 may mount to upright support 106b alone. Upright support 106b includes a double row of apertures 118 and can thus accommodate two support arms. The overall width of such a single upright support 106b may be varied to accommodate varying shelf lengths. As such, it is contemplated that at least one upright support is all that is required at a minimum for shelf mounting.

(48) It will be recognized from the foregoing that all of the componentry of shelf 108 may be readily assembled and disassembled without the use of any special tools, or without destroying or disfiguring any portion of shelf 108. Such a configuration is a distinct departure from prior designs which typically employ welded structures for their shelves, making the same heavy and generally cumbersome when the same are installed, or periodically removed for cleaning.

(49) It will also be recognized from the foregoing, that shelf 108 presents a highly modular design. Indeed, as one non-limiting example, shelf 108 may be readily adapted to a shelf having half of the length shown by remounting one of support arms 182 on upright support 106b, and utilizing shorter support bars 184. Thereafter, two deck panels (instead of the four shown) can then be snapped onto these shorter support bars 184.

(50) FIG. 14 illustrates a cross section taken in the region of the interface between a mounting post 188 of the left-most support arm 182 shown in FIG. 13 and rear support bar 184. As can be seen in this view, mounting post 188 is situated within a channel 196 of support bar 184. An identical configuration exists at the other end of this support bar 184, as well as at both ends of the front support bar 184 shown in FIG. 13. Each support bar 184 is supported by two mounting posts 188 by resting upon the same, without being permanently attached to these mounting posts 188, and thus presents a selectively removable style of assembly. It is also contemplated that channel 196 of each support bar 184 may be open sided as shown, or may be partially or fully enclosed in the event that support bars 184 are partially or entirely tubular elements, as opposed to having a generally U-shaped cross section as shown.

(51) With reference now to FIG. 15, the same illustrates an exploded view of a support arm 182. Each support arm 182 includes a main body 194 and an adjustable plate 198 mounted to main body 194. Each mounting post 188 is fixed to, and depends from, main body 194 as shown. Adjustable plate 198 attaches to main body 194 via a threaded fastener 200 as shown. Threaded fastener 200 extends through an aperture 202 of main body 194 and a wing nut or the like may then be used to tighten main body 194 and adjustable plate 198 together. Adjustable plate 198 also includes mounting features 204 which are received in the apertures 118 of upright supports 106a-c (see e.g. FIG. 2). These mounting features 204, however, can take any suitable form so as to facilitate the mounting of shelf 108 to any pre-existing structure.

(52) Adjustable plate 198 also includes a pin 206 which is received in one of a plurality of apertures 208 (see FIG. 16) formed in main body 194. The angular presentation of each support arm 182 as it extends outwardly in a cantilevered manner from its associated upright support 106a-c is governed which of the apertures 208 pin 206 is received in. For example, as may be seen in FIG. 16, when pin 206 is received in the upper most aperture 208, main body 194 is essentially level, e.g. horizontal, compared to adjustable plate 198. However, by removing any hardware securing fastener 200, one may reposition adjustable plate 986 relative to main body 194 (or vice versa) and insert pin 206 into a different one of apertures 208.

(53) For example, and turning now to FIG. 17, the same illustrates pin 206 in the third aperture down on main body 194. This causes main body, and hence support bars 184 and deck panels 180a-d mounted to supports bars 184 to, to tilt as shown. As a result, by this expedient manipulation, the user can readily govern the angle of shelf 108. Such a configuration is advantageous, for example, where the user desires to angle shelf 108 to provide a gravity feed function.

(54) FIG. 18 illustrates another perspective view of deck panel 180a, and in particular shows a bottom surface 112 thereof. Deck panel 180a includes a honeycomb strengthening structure 214 depending from its bottom surface 212. A front and a rear channel 216 extend through this honeycomb structure 214 for receiving each support bar 184, respectively, therein. Each channel 216 includes finger tabs 218 which may snap around its associated support bar 184 to secure deck panel 180a to support bars 184. Although a front and rear channel 214, 216 are shown, the number of channels utilized may be varied to accommodate fewer or greater support bars 184.

(55) With reference to FIGS. 12 and 18, adjacent each finger tab 218 is an aperture 223 extending through the upper surface and bottom surface of deck panel 180a. As illustrated in FIG. 18, the apertures 223 align with corresponding catch portions 219 of the adjacent finger tab 218. In this example, the catch portions 219 and apertures 223 are horizontally elongated.

(56) Each finger tab 218 includes a catch portion 219 that extends from a leg portion 221. Gaps 225 are formed between the finger tabs 218 and at least the catch portion 219 thereof and the adjacent wall portions 227 of the strengthening structure 214. Wall portions 227 have faces that define channels 216 therebetween.

(57) Ribs 231 extend from the bottom surface of the deck panel 180a. The ribs 231 extend between wall portions 227 on opposed sides of a corresponding channel 216. Wall portions 227 extend a greater distance from bottom surface 212 than ribs 231. In this example, the ribs 231 extend generally parallel to an axis that is perpendicular to a horizontal axis defined by the channels 216, i.e. parallel to an axis extending between the front and rear ends of the deck panel 180a.

(58) Further, deck panel 180a also includes a wire baffle support 230 for mounting a baffle plate thereto. Such a baffle plate may take on any form useful for directing air flow in a desired path. This wire baffle support 230 is slidable relative to deck panel 180a to allow for selective positioning of such a baffle plate.

(59) The above introduced interlocking capability of deck panels 180a-d is achieved via interlocking features arranged adjacent opposed side edges of each deck panel 180a-d. In the example of deck panel 180a shown, these interlocking features include a plurality of tabs 220 adjacent one side edge which extend downwardly from bottom surface 212 as shown. These interlocking features also include a lip with a plurality of openings 222 arranged adjacent the other side edge as shown. Tabs 220 are received in openings 222 of an adjacent deck panel. Likewise, openings 222 receive tabs 220 of an adjacent deck panel. This interlocking feature ensures that adjacent deck panels cannot laterally move along support bars 184 relative to one another once interlocked. Although described as identical, it is also contemplated that end panels may be employed as the left-most and/or right-most panels in the row of interlocked deck panels. In the case of a right-most end panel, the same would omit the lip and openings 222 to provide a cleaner edge on the right most side of the shelf surface. In the case of the left-most end panel, the same would omit the tabs 220 for the same purpose.

(60) FIG. 19 illustrates one tab 220 interlocked in one opening 222. Tabs 220 vertically enter openings 222. Once situated, tabs 220 are horizontally constrained within openings 222 due to their complimentary dove-tail shape. As a result, adjacent deck panels cannot laterally move along support bars 184 relative to one another once interlocked.
