-- smzu MP 1 CENTER CHANNEL ADJUSTABLE DISPLAY AND VENDING RACK The invention relates to racks for the display and sale of merchandise and is of a type which has been popular in the display and sale of bottled soft drinks in such locations as supermarkets and food stores in general where the goods is handled as a self-service item and moves relatively rapidly. The invention follows in general the principle disclosed in Patterson, U.S. Pat. No. 2,637,445 wherein trays which support the merchandise are more in the nature of dividers, in that the weight of articles on each tray is passed downwardly to the articles on the tray next below, and so on downwardly to the supporting surface on which the entire unit is mounted. Each tray has a pivoted attachment to a vertical rear support on which it is mounted in such fashion that it can be adjusted up or down depending upon the height of articles to be merchandised. After the tray has been emptied, a spring tilts the tray upwardly out of the way so that the articles on the next lower tray are displayed for sale.
Although display racks of the type described have been in popular demand for considerable time, some limitations have been experienced. The supports heretofore employed have featured primarily two vertical slideways in which opposite sides of each tray are secured. Duplicating the mounting and attachment necessitates balancing the adjustment on both sides one with the other so that the tray will always be perfectly horizontal and the arrangement and construction is such that installation, servicing and cost has hampered to a degree acceptance of an overall principle which has appreciable fundamental ad vantages.
It is therefore an object of the invention to provide a new and improved display rack in which the trays are independently adjustable and adapted to move out of the way when emptied, wherein the trays are attached to a rear vertical support at only one point thereby to simplify installation and adjustment, and to minimize the cost.
Another object of the invention is to provide a new and improved display rack the rear vertical support of which can be made, if preferred, of a single piece of material properly formed to provide a single channel of adjustment for the attachment of individual trays which can be quickly attached and quickly shifted in position by use of only the simplest tool permitting the supplier of merchandise to quickly adjust the rack to accommodate any one of a variety of different types of merchandise.
Also included among the objects of the invention is to provide a new and improved adjustable type display rack having single vertical rear supports of sufficient versatility to permit their being used either on a separate base or attached to a wall, and provided with a cover if need be together with a removable advertising panel which can be changed with the same case as the tray adjustment.
With these and other objects in view, the invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter set forth, pointed out in the appended claims and illustrated in the accompanying drawings.

In an embodiment of the device chosen for the purpose of illustration there is provided a base 10 substantially in the form of a box designed to have attached to it a rear support or channel member 11 in which is located a central vertically extending channel 12. Tray assemblies indicated generally by the reference character 13 are attached to the rear support in a manner permitting them to be adjusted up and down. An upper shelf 14 attached to the top of the rear support it overlies the uppermost tray assembly.
The base 10 which is designed to rest upon an appropriate supporting surface 15 includes sidewalls 16 and 16', a front wall 17 and a top 18. At the rear of each sidewall is a lug bracket 19, attached to the respective sidewall by some appropriate means as, for example, spot welding, the lug bracket 19 in each instance being provided with upper and lower lugs 20 and 21. The lugs, extending rearwardly as shown, provide respective recesses 22 and 23 so that when the lugs are pro jected through oversized slots 2 1 and 25, respectively, in the rear support 11, upper edges 26 and 27 will project into the respective recesses 22 and 23 thereby to lock the rear support 11 in position against the rear ofthe base 10 thereby to anchor the rear support in vertical position to the base.
The rear support which is in fact a channel member is customarily constructed of a single piece of sheet metal formed so as to provide opposite horizontally spaced vertical flanges 28 and 29. At the outer end of the flange 28 is a web 30 at the rear of which is an inwardly turned stiffening bead 31. Similarly, there is provided a web 32 for the flange 29, likewise provided with a stiffening bead 33.
The material of the rear support 11 moreover has inwardly bent portions forming legs 34 and 35 of the channel 12, the bottom of which consists of a web 36 including strengthening configurations 37 and 38 at the corners. Diagonal braces 39 and 40 on respectively opposite sides are substantially identical in form, the diagonal brace 39, for example, being attached by means ofa screw 31 to the web 30 and having a flat lower end 42, the lower end 42 of the brace 39 being adapted to project through a slot 43 in the top 18 of the base 10. A notch 44 on the flat lower end 42 provides a shoulder adapted to interlock with a front edge 45 of the slot 43 and a notch 46 at the opposite side of the lower end is adapted to interlock with a rear edge 47. Notches M and 46 on the lower end 42 of the diagonal brace 40 engage similarly in a slot 43'.
The tray assemblies 13, which might more properly be described as dividers, are identical in construction, except for the length of the uppermost tray assembly 13'. Each tray assembly consists of a wire grill 50 at the rear of which is a transverse bar 51. Loops 52,52 welded to the bar 51 provide hearing apertures 53, 53' for the accommodation of a pivot pin 54 which extends through holes 55, 55' in respective brackets 56, 56', thereby to attach the wire grill 50 pivotally to a midportion 57 of a vertically sliding body indicated generally by the reference character 58. A torsion spring 60 has one end 61 adapted to bear against the body 58 and another end 62 adapted to be spring pressed against the underside of the transverse bar 51 so that tension in the springs tends normally to elevate the wire grill to a vertical position as shown by the solid line positions of the uppermost shelf 13' and next upper shelfl3 in FIGS. 1 and 3.
For convenience and economy the body 58 has vertical side edges bent rearwardly to form respective slide shoes 63 and 64. Upper and lower flanges 65, 66 of lesser breadth serve to strengthen the body in a transverse direction.
As will be noted in FIG. 9 for example, the spread or distance between the slide shoes 63 and 64 is approximately the spread between rear ends of the legs 34 and 35 which form the channel 12, but the spread is substantially greater than the distance between corners 67 and 68, the channel 12 being of what is commonly termed a dovetail" shape. Proportioned as shown the body 58 is interlocked in the channel 12 where it is free to slide in a vertical direction but confined inwardly because of the sloping direction of the legs 34 and 35. The sliding operation as described permits each tray assembly to be adjusted vertically in the channel 12 on the rear support 11. A single-tightening screw 69 which extends through a threaded hole 70 in the midportion 57 can be forced against the web 36 of the channel 12, thereby to anchor the tray assembly in the selected vertical position of adjustment, as shown effectively in FIG. 8.
What has been previously described as the upper shelf 14 may be considered as a cover member or may be used in fact as a special shelf. In the form of device of FIGS. 1, 2, 3, 5, and 6, for example, the shelf consists of a plate 73 having upturned side edges 74, 74', a front edge 75 and rear edge 76. At the opposite ends of the rear edge 76 are tabs 77, 77 which extend downwardly at the rear of the rear support 11, as shown in FIG. 5, and which are attached to the respective beads 31, 33 by self-tapping screws 78. Triangular gusset braces 79, 79' on opposite sides are secured to the respective flanges 28 and 29 also by means of self-tapping screws 80.
The upper shelf 14, as shown in FIGS. 1 and 3, is located high enough above the uppermost tray assembly 13 so that when the uppermost tray assembly is empty and folded upwardly by spring action, it can swing completely beneath the upper shelf 14 as can also the upper tray assembly 13. As noted especially in FIGS. 1 and 3, the tray assemblies are adjusted with respect to their position on the rear support so that they are level when resting upon the tops of cartons of bottles, for example. Arranged in this fashion, the weight of bottles on the topmost loaded tray assembly is passed downwardly to the bottles on the next lower tray assembly and so on down to the base and thence to the supporting surface 15. What is significant is that the spacing of the tray assemblies can be easily accomplished merely by loosening the screw 69 so as to shift the tray assembly up or down depending on the height of the bottles loaded on the tray assembly next beneath it. The entire device, moreover, assembles with appreciable ease from a knockdown condition in that the rear support 11 can be readily mounted on the base 10 merely by extending the lugs 20, 21 through the appropriate slots 24, 25, then fastening the diagonal braces 39, 40 by a single screw 41 each at the top and by merely projecting the bottom ends through the respective slots 43, 43'. The device can be disassembled with equal ease by merely reversing the process.
A second form of mounting the rear support 11 may be one merely of confining upper and lower ends by use respectively of an upper channel member 83 and lower channel member 84. The upper channel 83 has a relatively narrow forward flange 85 and relatively longer rearward flange 86, and similarly the lower channel 84 is provided with a relatively narrow forward flange 87 and relatively wider rearward flange 88. There is no real necessity for anchoring the channel membars to a vertical wall structure 89 inasmuch as the tray assemblies, whether it be the narrow tray assembly 13 or the wide tray assembly 90, as shown in FIG. 11, do not actually support any of the merchandise, but are merely separators between goods below and above the tray assembly. When a wide tray assembly is used, like the tray assembly 90 as shown in FIG. 11, an appropriate rear support 11' is merely provided with wider flanges 28' and 29, the rear supports being stacked side by side and retained at respective upper and lower edges by the upper and lower channel members 83, 84 as already described.
So that the upper channel member 83 may be releasably retained in its position on the tops of the rear supports, a hole 91 is provided in the web 36, the location of which matches a dimple 92 on the rearward flange 86 of the upper channel member 83 so that the dimple can snap into the hole when the channel member is applied, thereby to releasably detain the parts in assembled position.
When the rear supports are retained as shown and described in connection with FIG. 11, the arrangement is such as to provide a ready opportunity for making use of an advertising display panel 95. To accomplish this, recesses 96 and 97 are provided in the respective flange 28 and 29, as shown in FIG. 14. correspondingly located slots 98 and 99 are also provided. At the upper edge of the display panel are tabs 100 and 101 designed to be received in the respective recesses 96 and 97. Similar tabs 102 and 103 at the lower edge of the display panel are adapted to be received respectively in the slots 98, 99. To assemble the display panel on the rear support, the tabs 102, 103 are first inserted into the slots 98, 99, the display panel 95 then tilted backwardly into engagement with the flanges 28, 29, causing the tabs 100, 101 to fall into the recesses 96, 97, after which the upper channel member is pushed into place so that the forward flange 85 locks the tabs 100, 101 in their positions, as shown in FIG. 13.
The arrangement of FIG. 11 also makes possible employment of a deeper upper tray 105. The upper tray 105 is pro vided with a bottom 106, sidewalls 107, 108, and if desired, a conventional front wall (not shown). A stiffening wall 109 of lesser height is shown at the rear. For locking the upper tray 105 is position, special lug brackets 110, 110' are employed fastened to the rear of the respective sidewalls 107, 108, as for example by bolts 111. On the lug brackets are upwardly extending hooks 112, 112 and downwardly extending hooks 113, 113', the upwardly extending hooks being longer than the downwardly extending hooks. Upper slots 114, 114' on the respective flanges 28, 29 accommodate the upwardly extending hooks 112, 112 and lower slots 115, 115' accommodate the downwardly extending hooks 113, 113'. For mounting the deeper upper tray 105, the upwardly extending hooks are first projected into the slots 114, 114' and the lug brackets moved up until the downwardly extending hooks 113, 113 can be projected into the slots I15, 115. The entire lug bracket is then moved downwardly slightly as shown in FIG. 16 until the downwardly extending hooks engage behind the flanges 28, 29 in which position the upwardly extending hooks also remain engaged behind the flanges, thereby releasably'locking the respective lug brackets and the upper tray 105 in position. The arrangement permits the upper tray to be quickly applied whenever needed as, for example, when a display panel is not to be used, or the upper tray removed and the display panel substituted with equal ease.
