SUMMARY OF THE INVENTION The general aim of the'present invention is to provide in a stand of the above character novel connections between the base panel and the side panels and comprising keys and keyways which can be assembled and interlocked quickly and conveniently to form joints hold ing the base and side panels in relatively rigid U-shaped relation during service use while permitting easy disascally attractive and structurally sound alinement betweenthe assembled panels while enabling connection of either of the side panels to either end of the base.
These and other objects and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT and draped downwardly over the upper ends of the side panels so as to be held in an open position.
Herein, the side panels 11 and the base 12 all are molded from relatively rigid plastic and each comprises a flat plate, the base being rectangular in shape and being formed with a downwardly projecting peripheral flange 15 (FIG. 2) adapted to rest on a cabinet or the like. The two side panels are identical to one another and each is formed with a peripheral flange 16 projecting inwardly from the inboard side of the panel. As shown in FIGS. 1 and 2, the top and bottom surfaces 17 and 18 of each side panel are flat while the side edge surfaces 19 are concavely curved to enhance the appearance of the panel. The upper ends of the concave side edge surfaces 19 of each panel merge with the ends of the top surface 17 on a rather sharp reverse curvature and, at their lower ends, the concave edge surfaces terminate adjacent vertical side edge surfaces 20 (FIG. 2) leading upwardly from the ends of the bottom surface 18.
In accordance with the present invention, keys 21 are formed on and depend from the lower surfaces 18 of the side panels 11 and are sized to fit into and interlock releasably but rigidly with recesses or keyways 23 in the base 12 to enable quick assembly and disassembly of the stand 10 when the latter is to be used and then subsequently knocked down and stored. Moreover, the base 12 is uniquely formed to initially locate the side panels 11 in the correct positions on the base and 'to guide the keys into the keyways during assembly so that the user may conveniently insert the keys into the keyways without difficulty.
More specifically, two keys 21 are molded integrally with and spaced along the bottom surface 18 of each side panel 11. One key is located near one extreme end of the bottom surface 18 (see FIG. 5) while the other key is spaced horizontally from the opposite end of the bottom surface by a distance approximately equal to the length of the key. Each key is shaped as a rectangular plate which is disposed in a generally horizontal plane and whose inboard edge is substantially coplanar with the inner edge of the flange 16 on the side panel, the outboard edge of the key being spaced inwardly from the outer face of the side panel. Narrow webs 25 (FIG. 3) of lesser width than the keys are substantially centered relative to the keys and join the latter integrally to the bottom surface 18 of the associated side panel.
In carrying out the invention, depressed right angular steps are formed along two opposite margins of the base 12 (see FIGS. 2 and 3) and, as a result, the upper surface 30 of each margin is spaced below the upper surface 31 of the main portion of the base while an upright wall 33 is defined between the two upper surfaces for locating and backing the side panel 11. The keyways 23 are formed through and open upwardly from the depressed margins and are located adjacent the opposite ends of the margins, there being two keyways extending along each margin to correspond to the keys 21 on the side panel ll. Each keyway comprises a wide rectangular slot 35 (FIG. 5) of slightly greater width than the key and formed with parallel inner and outer edges. The inner edge of each slot 35 is coplanar with the vertical locating wall 33 while the outer edge of the slot is spaced slightly inwardly of the extreme outer periphery 15 of the base.
As shown in FIG. 5, one of the pair of wide slots 35 in each depressed margin of the base 12 is located near one extreme end of the margin while the other wide slot is spaced some distance from the opposite end of the margin, the positioning of the slots relative to the ends of the margins corresponding inversely to the positioning of the keys 21 relative to the ends of the bottom surface 18 of the side panel 11. Leading from one end of each wide slot is a narrow rectangular slot 37 whose width is less than the width of the keys 21 and just slightly greater than the width of the connecting webs 25. The edges of each narrow slot 37 parallel those of the associated wide slot 35 and are spaced inwardly of and centered relative to the edges of the wide slot. Both narrow slots 37 in the same depressed margin lead in the same direction from the associated wide slots 35 and thus the closed end of one narrow slot is located near one end of the margin while the closed end of the other narrow slot is located near the midpoint of the margin.
To assemble the stand 10, each side panel 11 is located in an upright position with its flange 16 facing inwardly and is lowered endwise toward the upper surface 30 of the depressed margin in the base 12 while being held offset horizontally from one end of the margin to cause the key 21. located near the end of the panel to be in approximate registry with the mediately located wide slot 35 and to cause the other key to be in approximate registry with the wide slot at the end of the margin (see FIG. 2). As the panel is lowered, the inner edges of the keys 21 and the bottom inboard edge of the flange 16 engage the locating wall 33 and thereafter guide the panel edgewise and downwardly as the keys are telescoped downwardly into the wide slots 35 (see FIG. 6). By virtue of such engagement, the assembler can easily feel when the keys are alined horizontally with the wide slots thereby to enable quick and convenient insertion of the keys into the slots.
After the keys 21 have been inserted into the wide slots 35, the side panel 11 simply is moved edgewise and horizontally to slide the webs into the narrow slots 37 and to cause the keys to lock beneath the edge portions of the narrow slots as shown in FIG. 7, the bottom inboard edge of the flange 16 engaging the locating wall during such movement to insure alinement of the webs with the narrow slots prior to entry of the webs into the slots. The side panels may be quickly disassembled from the base 12 and flattened for storage simply by reversing the assembly steps. I
In the assembled stand 10, the bottom inboard edge of the flange 16 is engageable with the locating wall 33 to restrict inward and downward tilting of the side panel 11 under the weight of the garbage in the bag 13. Such engagement, together with the interlocking fit be tween the keys 21 and the narrow slots 37, make the side panels substantially rigid with the base and capable of supporting the weight in the bag. As shown in FIGS. 3 and 4, the interlocking fit between the keys and the narrow slots is rigidified by inclining the upper and outer surfaces 40 of the keys downwardly and outwardly at a small angle a. The inclined surfaces 40 seat against similarly inclined bevels 41 (FIG. 4) on the outer unclersurfaces of the narrow slots to prevent rocking of the side panel. In addition, two raised ribs 45 (FIGS. 3 to 5) are formed at spaced locations on the upper surface of each side margin between the keyways 23. The vertical distance between the upper surfaces of the ribs and the lower surfaces of the bevels 41 is somewhat greater than the vertical distance between the surfaces 40 of the keys 21 and the bottom surface 18 of the side panel 11. Thus, the ribs cause the midportion of the flange 16 to flex or bow upwardly somewhat to keep the upper surfaces of the keys seated tightly in the keyways. As a result, a relatively tight but releasable fit can be maintained between the upper surfaces of the keys and the lower surfaces of the keyways without need of forming the keys and keyways to extremely close tolerances. In addition, the ribs offer frictional resistance against edgewise sliding of the side panels on the base.
To help keep tension on the bag 11, the upper inner surface (FIG. 3) of each key 21 is inclined downwardly and inwardly from the horizontal at an angle b which is slightly less than the angle a. In addition, the webs 25 are inclined downwardly and outwardly from the vertical at an angle equal to the angle b. As a result, the side panels 11, when installed, tend to lean outwardly just slightly as shown in FIG. 4 to keep the mouth of the bag stretched open.
importantly, all of the surfaces of each side panel 11 are flush with the corresponding surfaces of the underlying base 12 in the assembled stand 10 so that the stand presents an attractive appearance. To help achieve the flush relationship, the inner edge portions of the narrow slots 37 project horizontally from the 10- eating wall 33 by a distance not greater than the horizontal depth of the inner grooves defined between the upper surfaces 50 of the keys 21 and the bottom surface 18 of the side panel and, because the outer edge portions of the narrow slots fit snugly into the outer grooves, the bottom inboard edge of the flange 16 lies closely adjacent the locating wall 33. In addition, the
width of the flange 16 is substantially equal to the width of the upper surface 30 of the depressed margin of the base 12 so as to make the outboard face of the panel generally flush with the corresponding vertically extending flange 15 on the base. Finally, the spacial relationship between the webs 25 and the narrow slots 37 is such that the webs engage the closed endsof the slots and prevent further edgewise sliding of the side panel 11 at the same time the vertical edge surfaces 20 on the panel move into flush alinement with the underlying flange 15 on the base. Accordingly, the stand presents a pleasing appearance since the surfaces of the panels conform to those of the base. i
Advantageously, the keyways 23 in one of the depressed margins of the base 12 are oriented oppositely of the keyways in the other margin to enable use of either side panel 11 at either end of the base and to avoid the need of molding left and right hand panels. That is, the narrow slots 37 in one margin lead from their respective wide slots 35 in a direction opposite to that of the narrow slots in the other margin. In addition, the end and mediately located wide slots 35 in one margin are located generally diagonally of their counterparts in the other margin. Thus, by turning one of the panels side-for-side, the keys 21 on the panel may be alined with and inserted in the keyways 23 at the opposite end of the base.
From the foregoing, it will be apparent that the present invention brings to the art a new and improved stand 10 which may be easily assembled and disassembled but which, when assembled, is adequately rigid to support the weight normally imposed on the stand. The side panels 11 may be used interchangeably at either end of the base 12 and conform to the lines of the base to enhance the appearance of the stand.
