Claim 8

A drawer comprising opposed upright metal side panels and an upright rear panel spanning said side panels, upper and lower parallel ribs integral with and extending along said side panels intermediate the upper and lower edges thereof and protruding outwardly from the outer sides of said panels, said upper and lower ribs defining downwardly and upwardly opening channels, respectively, an elongated drawer guiding track mountable on the outer side of each side panel, each of said tracks being of outwardly opening channel-shaped cross-section and being formed by upper and lower flanges bridged by an upright plate, a series of longitudinally spaced lugs struck from the upper edge portion of said plate and defining upwardly extending lips projecting inwardly from the plane of the plate, a series of longitudinally spaced lugs struck from the lower edge portion of said plate and defining downwardly extending lips projecting inwardly from the plane of the plate, the upwardly extending lips of each plate being fitted into said downwardly opening channel of the respective side panel and the downwardly extending lips being fitted into the upwardly opening channel to locate said track in a fixed vertical and lateral position on said side panel.

Claim 9

A drawer as defined in claim 6 in which said upwardly eXtending lips are staggered longitudinally of said track with respect to said downwardly extending lips.

Claim 10

A drawer as defined in claim 6 in which said lips lie inwardly of and in face-to-face relation with said ribs, said ribs being mashed inwardly into clamping engagement against certain of said lips to anchor each track in a fixed longitudinal position on its respective side panel.

Claim 11

A drawer comprising opposed upright side panels and an upright rear panel integral with and spanning said side panels, said panels being formed from a single elongated strip of metal having a pair of longitudinally spaced and transversely extending bends intermediate its ends to define right angular corners at the junctions of said side panels with said rear panel, top and bottom ribs extending along the upper and lower edges of said panels and protruding outwardly from the outer sides thereof, an intermediate rib extending along said panels between said top and bottom ribs and protruding outwardly from said panels, notches formed in said top and bottom ribs at each of said corners to facilitate bending of said strip at the junctions of said panels, and an inwardly mashed depression formed in said intermediate rib at each of said corners to facilitate bending of the intermediate rib during bending of said strip.

Claim 12

A drawer comprising opposed upright side panels and an upright rear panel integral with and spanning said side panels, said panels being formed from a single elongated strip of metal having a pair of longitudinally spaced and transversely extending bends intermediate its ends to define right angular corners at the junctions of said side panels with said rear panel, top and bottom ribs extending along the upper and lower edges of said panels and protruding outwardly from the outer sides thereof, an intermediate rib extending along said panels between said top and bottom ribs and protruding outwardly from said panels, notches formed in said top and bottom ribs at each of said corners to facilitate bending of said strip at the junctions of said panels, and an inwardly mashed depression formed in said intermediate rib at each of said corners to facilitate bending of the intermediate rib during bending of said strip.

Claim 13

A drawer as defined in claim 9 further including an additional intermediate rib paralleling said one rib and located between said top and bottom ribs, said additional rib protruding outwardly from the outer sides of said panels and being formed with inwardly mashed depressions located at said corners, the upper one of said intermediate ribs defining a downwardly opening channel and the lower one of said intermediate ribs defining an upwardly opening channel, an elongated drawer guiding track extending along the outer side of each of said side panels, each of said tracks having an outwardly opening channel-shaped cross-section and each being formed by upper and lower flanges bridged by an upright plate, and means on each of said tracks and fitted into said channels.

Claim 14
