## Background
FIELD OF THE INVENTION
The present invention generally relates to adjustable shelving systems. More particularly, the present invention relates to adjustable forward feeding display shelving system for storing and displaying merchandise of a variety of shapes and sizes and urging such merchandise towards the front of a shelf. The shelving system is configured to organize merchandise on the shelf into rows.
BACKGROUND OF THE INVENTION
Shelving is used extensively for stocking and storing products or merchandise in a variety of stores. Most stores simply employ shelves on which merchandise is stocked. In such stores if the shelves are not at eye level, it is difficult for the customer to see the items being displayed unless they are located adjacent the front edge of the shelf. Such conventional shelves also make it difficult to rotate the product on the shelves, which involves moving the older stock to the front of the shelf and positioning new stock behind the older stock. This has to be done manually by an employee. Thus, for a number of important merchandising considerations, it is desirable that the merchandise be displayed at the front of a shelf so that the customer can see the merchandise and be induced to purchase such merchandise. For example, if 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 to maintain freshness. As mentioned, if the merchandise is not displayed at the front of the shelf, it may not catch the shopper's eye, which may cost the merchant sales.
In order to automatically move an item forward as the one before it is removed, numerous forward feed devices have been proposed. These devices generally fall into three categories. The first category is inclined tracks, which rely on gravity to feed, slide or roll products forward. Gravity feeding is somewhat unpredictable in that various materials slide easier than others because of different weights and frictional interfaces between the products and the track. A second category employs conveyor belts, which still use gravity to effect forward movement. These devices are typically cumbersome, expensive and complicated due to the need to properly tension and track the conveyor belts. A third category uses spring biased paddles in a pusher system to feed the product forward. Such pusher systems have been found useful for certain merchandise.
Forward feed devices are usually associated with divider walls. Normally, a divider wall is located on either side of, for example, a pusher system. Both the pusher system and the divider wall are mounted to at least a front rail or front mounting member in order to allow a spacing of the pusher systems and divider walls on a shelf. In some known systems, the divider walls are separate from the pusher systems. In others, the divider walls and pusher systems are of one piece. In either case, the divider walls and pusher systems can be slidably mounted on the front rail or mounting member. This, however, has some disadvantages. Such disadvantages have to do with the fact that as the merchandise is being urged forward by the pusher, the merchandise may urge the dividers to slide laterally away from each other along the mounting member thus interfering with adjacent rows of merchandise, possibly making such merchandise more difficult to retrieve. This is particularly true with cans and other merchandise having rounded sides, since with such merchandise one item can rotate in relation to another as it is being pushed forward.
Certain merchandising systems employ a design in which the divider wall and the pusher are locked to a front rail or mounting member so as to prevent a sideward sliding thereof. However, with these known designs, the dividers and the pusher systems have to be physically removed from contact with the front rail in order to provide lateral adjustability thereto. The known systems also have other disadvantages.
Accordingly, it has been considered desirable to develop a new improved shelf divider system which would overcome the foregoing difficulties and others while providing better and more advantageous overall results.
SUMMARY OF THE INVENTION
In accordance with the present invention, a new and improved adjustable shelving system is provided. According to one aspect of the present invention, a shelving system comprises an elongated mounting member operationally securable to an associated elf, the mounting member comprising an approximately vertically oriented wall and an approximately horizontally oriented wall. A track is received on the mounting member in a non-sliding manner, wherein the track extends transversely to a longitudinal axis of the associated shelf. An elongated rail extends longitudinally along the track. A spring urged pusher is slidably mounted in relation to the rail. A slot extends transversely along a bottom face of the track. A first smooth contact surface is located on the mounting member approximately horizontal wall and a second smooth contact surface is located on the track, in or near the slot. The second contact surface engages the first contact surface to retard a sideward sliding motion of the track in relation to the mounting member.
According to another aspect of the present invention, a shelving system comprises an elongated first mounting member operationally securable to a front portion of an associated shelf, the first mounting member comprising an approximately vertically oriented wall and an approximately horizontally oriented wall. A track is received on the first mounting member in a non-sliding manner wherein the track extends rearwardly over the associated shelf. An elongated rail extends longitudinally along the track. A spring urged pusher is slidably mounted in relation to the rail. A slot extends transversely along the bottom face of the track. A first set of teeth extend at least partially from a rear face of the first mounting member approximately horizontally oriented wall and a second set of teeth extend from the track adjacent the slot. The second set of teeth engage the first set of teeth to retard a sideward sliding motion of the track in relation to the first mounting member.
According to a still further aspect of the present invention, a shelving system comprises an elongated mounting member operationally securable to an associated shelf, the mounting member comprising an approximately vertically oriented wall and an approximately horizontally oriented wall. A cooperating member is received on the mounting member in a non-sliding manner wherein the cooperating member extends transversely to a longitudinal axis of the associated shelf. A slot extends transversely along a bottom face of the cooperating member. A first contact surface is located on the mounting member. A second contact surface is located on the cooperating member in the slot. The first contact surface engages the second contact surface to retard a sideward sliding motion of the cooperating member in relation to the mounting member. The first contact surface includes a first mating face and the second contact surface includes a second mating face. The first and second mating faces are oriented at an acute angle in relation to each other.
According to a yet further aspect of the present invention, a shelving comprises an elongated mounting member operationally securable to the front portion of an associated shelf and extending along a longitudinal axis thereof. The mounting member comprises an approximately vertically oriented wall and an approximately horizontally oriented wall. A cooperating member is received on the mounting member in a non-sliding manner wherein the cooperating member extends rearwardly over the associated shelf. A slot extends transversely along a bottom face of the cooperating member. A first set of teeth extend at least partially from a rear face of the mounting member approximately horizontally oriented wall and a second set of teeth extend from the shelf divider in proximity to the slot. The second set of teeth engage the first set of teeth to retard a sideward sliding motion of the cooperating member in relation to the mounting member.
Still other aspects of the present invention will become apparent to those of average skill in the art upon a reading and understanding of the following detailed specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein the showings are for purposes of illustrating several preferred embodiments of the invention and not for purposes of limiting the same, FIG. 1 illustrates a first embodiment of a shelf divider system according to the present invention. In this embodiment, a mounting member or front rail 10 includes a vertically oriented wall 12. With reference also to FIG. 7, the vertically oriented wall 12 includes a first section 14, a first groove 16 and a second section 18. Also provided on the mounting member 10 is a horizontally oriented wall 20. Disposed between the horizontally oriented wall section and the vertical wall section 12 is a second groove 22. There is a recessed portion 26 with an opening 28 located in the horizontal wall 20. The wall 20 includes a front face 30, a top face 32 and a back face 34. Defined at the intersection of the top face 32 and the back face 34 is a first row or set of teeth 36.
Mounted in the first groove 16 is a front fence 40, as can be seen in FIGS. 1 and 8. As shown in FIG. 1, a suitable conventional fastener 42 can extend through the opening 28 in the horizontal wall 20 of the mounting member 10 so as to secure the mounting member in place on a subjacent shelf A, which has suitable apertures for this purpose. It should be appreciated that a plurality of such openings 28 may be provided on the front rail 10. It should also be appreciated that the fastener 42 is located in the recessed portion 26 of the horizontal wall so as to not interfere with shelf dividers or pusher tracks secured to the front rail. It can be appreciated from FIG. 1 that the mounting member 10 can be somewhat L-shaped in side view. Of course, the mounting member could also have other shapes, if so desired.
In this embodiment, a shelf divider and pusher track, which is of one piece, is disclosed. However, it should be appreciated that separate shelf divider walls and pusher tracks can also be employed with the mounting member or front rail 10 disclosed herein.
With continued reference to FIG. 1, a shelf divider 50 is mounted on the mounting member or front rail 10. The shelf divider includes a horizontally oriented base wall 52 and a vertically oriented divider wall 54. Located on a bottom face 58 the base 52 is a transversely extending slot 60. With reference now again to FIG. 6, the slot 60 includes a front face 62, a roof 64 and a rear face 66. Extending forwardly from the rear face are a set of rear protrusions 68. Defined on such protrusions is a second row or set of teeth 70.
With reference now to FIG. 3, the shelf divider base wall 52 has a first section 72 and a second section 74. Defined on the second section is a flange or rail 76. Positioned adjacent the flange is a channel or groove 78. A pusher member 80 is slidably mounted on the base wall second section 74. With reference now to FIG. 4, the pusher member 80 includes a vertically extending pusher wall 82 and a base wall 84. Connecting the pusher wall and the base wall are first and second brace walls or gussets 86 and 88.
Depending from the base wall 84 is a foot 90. In this embodiment, a first portion 92 of the foot can be aligned with the first brace wall 86, as best shown in FIG. 4. A second portion or flange 94 of the foot can be oriented approximately normal to the first portion 92 and can be parallel to a plane of the base wall 84. Thus, a somewhat U-shaped section is formed for accommodating the flange or rail 76 extending from the base wall second section 74. Protruding from a lower surface 96 of the base wall 84 is a rib or protrusion 98. The protrusion includes a pair of side walls 100 and 102. It should be apparent from FIGS. 4 and 5 that the second side wall 102 is spaced a considerable distance from a first side wall 104 of the channel or groove 78 but that the protrusion first side wall 100 is located adjacent the groove second side wall 106. Located on the base wall second section 74 are top rails 108 and bottom rails 110, as illustrated in FIGS. 4 and 5.
With reference again to FIG. 3, a coil spring 120 can be housed on the pusher member 80. More particularly, the coil spring is supported on the base wall 84 between the pair of brace walls. A section 122 of the coil spring extends through a slot 124 in the pusher wall 82. A front end (not illustrated) of the coil spring can be secured to a front portion of the shelf divider. In use, as the pusher 80 reciprocates on the track formed by a flange 76, the channel 78 and the rails 108 and 110, the pusher base 84 and foot 90 ride on the top and bottom rails 108 and 110 such that the lower surface 96 of the base wall contacts at least one of the top rails 108 while the second portion 94 of the foot or guide contacts the bottom rail 110. Due to the cooperation of the foot 90 and the protrusion 98 with the base wall second section 74, the pusher 80 can not be lifted away from the track. Rather, the pusher must be slid to an end of the track to be subsequently removed.
With reference now to FIG. 9, it can be seen that when the pusher 80 is fully retracted, it can at least partially extend past a rear wall 130 of the shelf divider 50. However, the pusher does not fall off the shelf divider as a rear edge 132 of the foot second portion 94 contacts a depending section 134 of the rear wall 130. Since the pusher can be retracted past the rear end of the divider member 50, a system of the present invention can be used on a shelf that is somewhat deeper than is the length of the divider 50. Thus, the present system is capable of accommodating shelving of the varying depths. Of course, if the shelf is no deeper than the length of divider 50 then no part of the pusher will be able to retract past the end of the divider as the pusher will contact the rear surface of the shelf. In order to stiffen the two brace walls 86 and 88, stiffening ribs 136 can be employed, as is shown in FIG. 9. Moreover, the pusher wall 82 can have an enlarged upper end 138 in order to better accommodate wider merchandise that is being urged forwardly on the track by the pusher member.
With reference again to FIGS. 6 and 7, it can be seen that the angle of the front face 30 in relation to a plane of the second groove 22 can be, for example, 71°. In contrast, the angle between the front face 62 and the roof 64 of the slot 60 located in the shelf divider 50 can be 70°. As a result, when the shelf divider is completely seated on the mounting member 10 a pinching action takes place between the front face 62 and roof 64 of the divider 50 and the front face 30 and top face 32 of the mounting member 10. Such pinching action locks the shelf divider 50 onto the mounting member to retard a sideward sliding motion of the shelf divider on the mounting member. Such pinching action is possible due to the resilient nature of the materials from which the shelf divider and the mounting member are made. If desired, these two components can be made of suitable conventional resilient materials, such as known thermoplastic materials. These will allow some relative flexing between the two as the shelf divider is mounted on or detached from the mounting member or rail. The two components can be made from the same material or from different materials. It should, of course, be appreciated that other suitable angles could be provided on the interengaging surfaces of the mounting member and the shelf divider to provide the desired pinching action or locking action.
Of course, such sideward sliding movement is also retarded by the interengaging sets of teeth 36 and 70 on the mounting member and the shelf divider respectively. To this end, the back face 34 is angled forwardly by 5° from the vertical. Similarly, the rear protrusions 68 are angled forwardly by 5° from the vertical. Thus, there is a mating engagement of the mounting member back face with the rear protrusion 68 of the shelf divider 50. In this embodiment, the pinch point occurs only at the engagement of the mounting member front face 30 with the shelf divider front face 62. However, it should be appreciated that such pinch points could be located at other positions along the engagement surfaces of the mounting member and shelf divider.
As is best seen from FIG. 8, the locking action of the shelf divider 50 on the mounting member 10 takes place when the shelf divider is fully lowered onto the mounting member. However, when a rear end of the shelf divider is slightly lifted, the shelf divider is rotated in relation to the mounting member. This action unlocks the shelf divider from the mounting member, disengages the two sets of teeth 36 and 70 and allows the shelf divider to be moved along the mounting member to a desired location. To this end, the shelf divider can either be slid along the mounting member or simply pulled away from the mounting member and laterally moved to the desired location and then reconnected with the mounting member.
With reference now to FIG. 10, an end wall 150 for the shelf divider system includes a base 152 and an upright portion 154. With reference also to FIG. 12, a transversely extending slot 156 is located adjacent a first end of the end wall 150. The slot 156 is adapted to accommodate the horizontal wall 20 of the mounting member 10. A front edge 157 of the divider is seated in the second groove 22. Also provided for the end wall 150 is a recessed area 158. Located in the recessed area are spaced first and second sockets 160 and 162. Cooperating with the end wall 150 is a flange 170, as illustrated in FIG. 11. The flange includes a first arm 172, and, spaced therefrom, a second arm 174. Each of these arms have a tooth 176 positioned on their distal end. The arms are adapted to extend through the sockets 160 and 162 so that the teeth protrude past the far edge of the base in order to clip or lock the flange 170 into place in the end wall 150. Provided on the flange are a plurality of slots 178 and apertures 180. These are meant to accommodate suitable conventional fasteners (not shown) in order to secure the end wall in place on the associated shelf.
With reference now to FIG. 13, a second embodiment of a shelf divider system according to the present invention is there illustrated. In this embodiment, a rail or mounting member includes a vertically oriented wall 192 having a first groove 194 and a horizontally oriented wall 196 as well as a second groove 198. Selectively secured to the rail is a divider 210 having a base wall 212 and a vertically oriented dividing wall 214. A transverse slot 218 extends across a bottom surface of the base. The base thus has a front edge 220 which is adapted to fit into the second groove 198 while the slot extends over the horizontal wall 196, as best shown in FIG. 14. In this embodiment, no teeth are employed. Rather, a smooth set of engaging walls is disclosed in this embodiment. Thus, the set of engaging walls can be even, free from irregularities, roughness or projections. The locking feature is achieved by suitably configuring the engaging surfaces of the slot and the mounting member horizontal wall, along the lines discussed in connection with FIGS. 6 and 7 hereinbefore.
In other words, a locking engagement can be achieved when the divider 210 is fully lowered onto the mounting member 190 because of the differing angles provided for the mating surfaces of the mounting member and the divider. Even a 1° difference in the angles of the front face 198 of the horizontal wall 190 and the front face of the slot 218 is adequate to provide the desired pinching or locking action. Such a 1° difference was disclosed in the embodiment of FIGS. 6 and 7. Of course, other suitable angular relationships between the mating faces could also be employed. In order to detach the divider 210 from the mounting member 190, an installer merely has to raise a distal end 222 of the divider 210 thereby disengaging the locking feature. At this point, the divider can then be slid in relation to the mounting member 190 along the second groove 198. Alternatively, the divider can be detached from the mounting member and then moved in relation to it. It should be appreciated that the mounting member or rail can be secured to a subjacent shelf adjacent a front edge of the shelf or adjacent a rear edge of the shelf.
With reference now to FIG. 15, a third embodiment of a shelf divider system according to the present invention is there illustrated. In this embodiment, a rear rail 230 is employed, instead of a front rail. The rear rail or mounting member includes a vertically oriented wall 232, a groove 234, and a horizontally oriented wall 236. The horizontally oriented wall includes a top surface 238 and a front surface 240. A first set of teeth 242 is located at the intersection of the top surface and front surface of the horizontally oriented wall 236. Selectively secured to the rear rail 230 is a divider 250. The divider includes a base wall 252 and a vertically oriented divider wall 254. A transverse groove or slot 256 is defined in the base wall 252 adjacent a rear end of the divider. The location of the slot 256 is such as to accommodate a depending rear end 258 of the divider base wall.
With reference also to FIG. 16, the divider rear end 258 is shown as being seated in the groove 234. Provided in the slot 256 of the divider is a second set of teeth 260. These engage the first set of teeth 242 on the rear rail 230 so as to lock the divider in place on the rear rail. The divider 250 also includes a track 264 on which is mounted a pusher 268. The pusher can reciprocate along the track from adjacent the rear rail 230 to a forward position on a shelf on which the system is mounted. In this embodiment, a front wall 270 is provided for the track 264. The front wall can be of one piece with the divider 250 or it can be a separate element that is suitably connected to either the divider or to the shelf on which the divider is mounted.
With reference now to FIG. 17, a fourth embodiment of a mounting member 280 is there illustrated. In this embodiment, the mounting member includes a vertically oriented wall 282, a slot 284 and a horizontally oriented wall 286. The horizontally oriented wall includes a top surface 290 and a rear surface 292. A first set of teeth 294 is located at the intersection of the top surface and the rear surface. In this embodiment, a second set of teeth 296 is located in the slot 284. The teeth are spaced from a front surface 298 of the horizontally oriented wall and may contact a rear face 302 of the vertically oriented wall.
With reference now to FIG. 18, a fifth embodiment of a mounting member 310 according to the present invention is there illustrated. In this embodiment, the mounting member includes a vertically oriented wall 312, a slot 314 and a horizontally oriented wall 316. The horizontally oriented wall has a top surface 320, a front surface 322 and a rear surface 324. A set or row of teeth 328 is located in the slot 314. In this embodiment, the set of teeth does not contact either the front surface 322 of the horizontally oriented wall or a rear surface 330 of the vertically oriented wall. Rather, it is spaced from both. This can best be seen in FIG. 22 of the drawings.
With reference now to FIG. 19, a sixth embodiment of a mounting member 340 according to the present invention is there illustrated. In this embodiment, the mounting member includes a vertical wall 342, a slot 344 and a horizontal wall 346. The horizontal wall includes a top surface 350 and a front surface 352. A set of teeth 356 is located in the slot 344. In this embodiment, the set of teeth contact a rear surface 358 of the vertical wall 342, but do not contact the front surface 352 of the horizontal wall 346.
With reference now to FIG. 20, a seventh embodiment of a mounting member 360 is there illustrated. In this embodiment, the mounting member includes a vertical wall 362, a slot 364 and a horizontal wall 366. The horizontal wall has a top surface 370 and a front surface 372. A set of teeth 376 extend in the slot 364. The set of teeth contact the front surface 372 of the vertically oriented wall but do not contact a rear surface 378 of the vertically oriented wall.
With reference now to FIG. 21, an eighth embodiment of a mounting member 380 is there disclosed. In this embodiment, the mounting member comprises a vertical wall 382, a slot 384 and a horizontal wall 386. The horizontal wall includes a top surface 390 and a front surface 392. A set of teeth 396 extends along the slot 384. In this embodiment, the set of teeth extend from the horizontal wall front surface 392 to a rear surface 398 of the vertical wall. Thus, the set of teeth span the entire width of the slot 384.
With reference now to FIG. 23, a ninth embodiment of a mounting member 410 according to the present invention is there illustrated. In this embodiment, the mounting member or rail includes a vertical wall 412, a slot 414 and a horizontal wall 416. The horizontal wall includes a top surface 420, a front surface 422 and a rear surface 424. In this embodiment, a set of teeth 428 is defined on the top surface 420 of the horizontal wall 416. No teeth are defined on either the front surface 422 or the rear surface 424 of the horizontal wall 416. Nor are there any teeth defined on the vertical wall 412.
Finally, FIG. 24 illustrates a tenth embodiment of a mounting member according to the present invention. In this embodiment, the mounting member includes a vertical wall 442, a slot 444 and a horizontal wall 446. The horizontal wall includes a top surface 450, a front surface 452 and a rear surface 454. In this embodiment, a first set of teeth 458 is located on the top surface 450 on the horizontal wall. A second set of teeth 460 is located at the intersection of the horizontal wall top surface 450 and rear surface 454. A third set of teeth 462 is located in the slot 444. The third set of teeth does not contact either the front surface 452 of the horizontal wall or a rear surface 464 of the vertical wall. Rather, as in the embodiment illustrated in FIGS. 18 and 22, the third set of teeth is only connected to the base of the slot 444.
It should be appreciated that the various mounting members illustrated in, e.g. FIGS. 17–24 can be positioned at either the front edge of a shelf or the rear edge of the shelf, just as the mounting member of the embodiment of FIG. 1 is positioned adjacent a front edge of the shelf and mounting member of the embodiment of FIG. 15 is positioned adjacent the rear edge of the shelf.
In the previous embodiments, the mounting member is shown to have a vertical wall, a horizontal wall and a slot defined between these two walls. However, it should be appreciated that other types of mounting member designs are also contemplated. For example, as disclosed in FIG. 25, a mounting member 470 can have a somewhat different configuration as well. In this embodiment, the mounting member 470 includes a vertical wall 472 and a horizontal wall 474. In this design, there is no separate slot defined between the vertical wall and the horizontal wall. Also, in this design, there is a raised area or plateau 476 located on the horizontal wall. Mounted atop the raised area 476 is a set or row of teeth 478. As in the earlier designs, the teeth can cooperate with suitable teeth located on a divider element, a track element or a combination divider and track assembly, as previously disclosed herein. It can be appreciated that the cooperating divider, track or combination divider and track assembly would need to be suitably configured in order to be accommodated on the mounting member.
With reference now to FIG. 26, a yet twelfth version of a mounting member 490 is there disclosed. In this embodiment, the mounting member includes a vertical wall 492 and a horizontal wall 494. A set of teeth 496 is disposed on an upper surface 498 of the horizontal wall. In this design, the cooperating divider wall, pusher track or combination divider wall and pusher track is seated on the mounting member horizontal wall 494 and engages the teeth on the horizontal wall so as to retard a sidewards sliding motion of the cooperating member. It can be appreciated that the cooperating member would need to be suitably configured for this purpose.
In FIG. 27, there is disclosed a yet thirteenth embodiment of a mounting member 510 according to the present invention. In this embodiment, the mounting member includes a vertical wall 512 and a horizontal wall 514. The horizontal wall is provided with a raised area 516. In this embodiment, a row or set of teeth 518 are located on an upper surface 520 of the horizontal wall. The teeth are spaced both from the front surface 522 of the raised area 516 and a rear surface 524 of the vertical wall 512. For this embodiment, the cooperating divider wall, pusher track or combination divider wall and pusher track is suitably configured so as to engage the teeth 518. The cooperating member can also be configured to lockingly engage the raised area front surface 522, as discussed in connection with several of the embodiments previously mentioned.
In the embodiments discussed hereinbefore, either a front rail or a rear rail was employed. However, it should be recognized that both a front rail and a rear rail can be utilized as mounting members for mounting a combination shelf divider and pusher track or separate shelf dividers and pusher tracks. The use of two rail designs in general is known in the art. Therefore, it can be appreciated that two rails or mounting members can be employed in the adjustable shelving system of the present invention.
In the various embodiments disclosed herein, the contact surface located on the divider member or track or member which cooperates with the mounting member or front rail is disclosed as being located in the slot. However, it should be appreciated that the contact surface, which can be a set of teeth, can also be located near the slot, adjoining the slot, in proximity to the slot, in the vicinity of the slot and the like. Thus, the second contact surface does not necessarily have to lie within the slot or be contiguous with or abutting, touching or in juxtaposition with the slot. Rather, it can be in the neighborhood of the slot. The location of the second contact surface, which can be a second set of teeth, is determined by the location of the first contact surface, which can be a first set of teeth, on the mounting member or track. All that is necessary is that the two engage each other and cooperate with each other in order to retard a sideward sliding motion of the divider track or cooperating member in relation to the elongated mounting member or rail.
While the embodiments disclosed herein illustrate the use of a slot, i.e., a transverse groove or opening, it should be appreciated that other types of openings could be provided along the bottom face of the cooperating member, track or divider assembly disclosed herein. Thus, any type of suitable aperture, way, path, channel, passage or other suitable gap could be employed. For example, a set of notches could be provided along the bottom face instead of a single slot if the mounting member or rail were suitably configured. Thus, the term “slot” as used herein is intended to include all such openings, apertures, holes, orifices, passages, grooves, troughs, channels, indentations and the like.
The invention has been described with reference to preferred embodiments. Obviously, modifications and alterations will occur to others upon the 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 or the equivalence thereof.
