DETAILED DESCRIPTION OF THE DISCLOSURE The invention described below involves the fabrication of a single molded plastic drawer element which includes the bottom, two sides and rear panels of the drawer. This element is molded in a flat coplanar condition, as if thetwd' 'sides and rear of the drawer had been pivoted downwardly along the line at which their respective lower edges join thebottom panel. This drawer element does not include the drawer front, which it is contemplated would be separately formed and connected to the disclosed drawer element by means beyond the scope of this invention.

Thus, what is involved here is a flat molded plastic part approximately 24 inches long, 14 to 24 inches wide (depending upon the width of the drawer), and generally about 0.150 inches thick.

The only portion of the drawer element with which.

this invention is concerned is the rear corner of the drawer, where provision must be made for interlocking the side and rear panels after they are folded up to their functional mutually perpendicular position with respect to the drawer bottom panel. Accordingly, FIG. 1

of the drawings is a view of the left rear comer portion ure. FIGS. 2,3 and 4'show successive stages of the ass'embling of the drawer, with the rear panel 14 and then side panel 12 being folded upwardly to the final assembled position of F1634, wherein the left rear cornrof the drawer is viewed in perspective from a point outside of and slightly above such corner.

7 As best shown in FIG. 5, the construction is generally a'simple flat panel, with a flexible thin-walled hinge line 16 joining the bottom and side panels 10, 12, respectively. A'suitable material for the present application is polypropylene, which combines the desired strength, rigidity and flexibility in thin sections. The hinge lines, such as hinge line 16, may be fabricated of a reduced thickness of approximately .025 inches.

As best shown in FIG. 6, a similar hinge line 18 joins the bottom panel and rear panel portions 10, 14, respectively; As best shown in FIGS. 1, 6 and 7, back or rear panel 14 is provided with an upstanding bottom flange 20 running closely adjacent to hinge line 18 across the full width of the drawer, and is further provided with similar upstanding side flanges 22 along each lateral edge of such panel. Bottom flange 20 nests flush into recess 24 along the rear upper face of bottom panel 10 when the drawer is in its fully assembled condition, as shown in FIG. 7. Similarly, side flanges 22 will nest flush into recesses 26 provided along the rear portion of side panel 12, as shown in FIGS. 2, 3 and 4. These flanges serve to reinforce the assembled construction, and provide a bearing or stop face to prevent overbending in the inward direction of the various panels.

The panels are interlocked together in their assembled condition by a series of tongue-groove formations integrally molded into the drawer element. The first cooperating tongue-groove pair consists of tongue 28 on the outside face of rear panel side flange 22 and groove 30 on the upper inner face of side panel 12.

As shown by a comparison of FIGS. 2 and 3, the first step of the assembly sequence is to fold upwardly and forwardly rear panel 14, which pivots about rear hinge line 18. Next, side panels 12 are folded upwardly and inwardly about their respective side hinge lines 16. As each side panel 12 approaches its ultimate vertical position, tongue 28 will snap into aligned groove 30 to establish an initial interlock between side panel 12 and rear panel 14. The drawer element is then in the condi tion shown in FIG. 3.

Assembly is completed by means of a side locking tab 32 which is integrally formed with the rear edge of each side panel 12 and joined thereto by a thin-walled hinge line 34. From the position of FIG. 3, side locking tab 32 is folded inwardly and forwardly about its hinge line 34, until groove 36 (see FIG. 2) on the inner face of tab 32 snaps over rearwardly projecting tongue 38 on the outside or rear face of back panel 14 (see FIG. 2). This step completes the assembly of the illustrated rear corner of the drawer.

As shown in FIGS. 4 and 7, a pair of horizontal vertically spaced parallel ribs 40, 42 traverse the width of the outer or rear face of drawer rear panel 14. The vertical spacing between upper rib 40 and lower rib 42 is such as to permit locking tab 32 to snugly swing between them as it moves from the position of FIG. 3 to that of FIG. 4. This feature, combined with the two pairs of tongue-groove connections 28, 30 and 36, 38,

' provide a firm and secure corner assembly.

3 First, rear panel 14 cannot move rearwardly relative to side panel 12, because such movement is resisted by tongue 28 (see FIG. 2). Rear panel 14 cannot move and because such movement would require that the upper comer of side locking tab 32 pass through upper rib 40 as it pivots about hinge line 16, which it cannot do as long as the tab is in the position shown in FIG. 4. Thus, movement of these panels in any directions is effectively resisted by the interlocking tongue and groove formations.

It will be appreciated that the drawer element described above can be shipped in a flat condition, that is, the condition shown in FIG. 1. At its ultimate destination, the drawer can be assembled rapidly by totally unskilled labor. i

This invention may be further developed within the scope of the following claims. Accordingly, the above specification is to be interpreted as illustrative of only a single operative embodiment of this invention, rather than in a strictly limited sense.

I now claim: I
