ATTORNEY DRAWER SUSPENSION BACKGROUND OF THE INVENTION categories: sliding, fixed rail, and telescoping rail. These are stated in the order of increasing cost, and also in the orderof smoothness of action. The telescoping rail system provides full roller mounting and full drawer support at complete extension. A sliding drawer mounting provides no rollers at all, and is usually associated with either low-cost structures, or with drawers that are comparatively lightly loaded and infrequently used. The fixed rail system forms an intermediate between the two extremes of cost, and the attempt is usually made by the designer to provide as much of the advantage of the telescoping rail system as possible within the economy of the single fixed rail at each side of the drawer. In this system, the drawer is supported at a point near the drawer'opening on rollers mounted on the rail, with the rear of the drawer carrying a second set of rollers'that are interengaged with flanges on the rails. Primary'design considerations in these systems include economy in the use of space within the cabinet,-both laterally and vertically, and the elimination of a requirement of an unduly large drawer opening to accommodate disengagement of the drawer and the slight vertical movement associated with automatic closing.
The drawer is frequently locatedlaterally at the drawer opening by flanges on the supporting rollers. Automatic closure is accomplished by providing a slant to the bottom edge of the drawer side positioned to induce the drawer to roll slightly down hill as the drawer nears the closed position. This slant is commonly supplemented by a slight offset in the supporting rail at the rear end of the drawer. The vertical movement inherently associated with this arrangement must take place withoutinterference from the rail structure, and without preventing placement of the roller flanges on the outside of the drawer.
SUMMARY OF THE INVENTION Supporting rails are mounted in the cabinet within the space defined by the vertical projection of the drawer, and preferably between the planes defining'the inside surfaces of the drawer sides. This position permits the bottom edge of the drawer sides to move down past the supporting rail to accommodate the vertical movement of automatic closure. The front rollers are mounted on the outsides of the rails, with the drawer being received between flanges on these rollers which bear against the sides of the drawer whenever a tendency to lateral displacement exists. With the roller flanges on the outside of the drawer, the drawer does not have to pass over the roller flanges on disengagement of thedrawer from the drawer opening.

DESCRIPTION OF THE PREFERRED EMBODIMENT The drawer generally indicated at is formed by the parallel sides 21 and 22, the back 23, the front 24 provided with the handle 24a, and the bottom panel 25. Thedrawer is received within the opening 26 in thecabinet structure 27. Opposite rails 28 and 29 are supported at the fronton brackets 30 and 31, which have tabs 32 and 33, preferably projection-welded to the rails in the position shown in FIG. 4. The rear extremities of these rails are received by the receptacles 34 and 35 secured to the member, 36 of the panel structure 27. The members 34 and 35 are preferably molded of plastic material, and are provided with slots receiving the ends of the rails. These receptacles, per se, form no part of the present invention.
The installation of the rails 28 and 29 with respect to the drawer is best shown in FIG. 8. The position of the rails is such that they are within the space between the planes defining the inside surfaces of the sides 21 and 22, so that the drawer can move downward past the rails without interference at the bottom edges of the sides 21 and 22. Rollers 37 and 38 are mounted on the outside of the rails, as shown in FIG. 8, on studs 39 and 40-secured directly to the rails. The rollers have flanges 41 and 42 disposed to bear against the outside surfaces of the sides 21 and 22 to prevent lateral displacement of the drawer with respect to the opening 26.
The inner extremity of the drawer is supported on the rollers 43 and 44 mounted, respectively, on brackets 45 and 46 secured to the back panel 23 with screws 45 a-b and 46 a-b.
These brackets are of conventional design. The rollers 43 and 44 are received between the flanges 47-48 and 49-50 of the respective rails (refer to FIGS. Band 14), and the rail 28 is additionally provided with the retaining flange 51 preventing lateral displacement of the roller embraced by that rail. Both of the rails are provided with conventional extension stops as 7 shown at 52 and 53, and the lower flanges of the rails are deformed as shown at 54 and 55m permit the rear rollers to move past the extension stops in the manner shown in FIG. 11. These arrangements are conventional, as in the cut-away provided in the upper flanges of the rails, as shown at 56 in FIGS.
10 and 11, for permitting the rear rollers to be withdrawn as the drawer is disengaged in the movement illustrated in FIG.
12. Reference to FIG. 11 will confirm thatthe withdrawal of flanges are outside of the vertical projection of the drawer.
Iclaim: 1. In combination with a drawer and a cabinet structure having an opening normally receiving said drawer, a drawer suspension system including opposite rails mounted in said cabinet structure underneath said drawer, and also including roller means mounted on said drawer and engaging said rails,"
wherein the improvement comprises: opposite front rollers mounted on said rails, respectively, and normally supporting said drawer, said front rollers each having a side flange disposed to engage the side of said drawer on lateral displacement thereof with respect to said cabinet structure, said front rollers being mounted on the sides of each of said rails remote from the other of said rails, and said rails are within the space between vertical planes defining the inside surfaces of said drawer sides. 7
2. A combination as defined in claim 2, wherein said drawer has a bottom panel and sides extending below said bottom panel, and said front rollers engage the bottoms of said drawer sides.
