  • Patent number: 5172971
    Abstract: A drawer is limited on its sides by metal side walls provided at their top with guide rails and at the bottom with a carrying flange for supporting a bottom plate of the drawer. The carrying flange is formed with stamped-out, flat retaining lugs bent up to extend from below into openings of the bottom plate, which drawer also comprises a rear wall mounted between the side walls. In order to permit a reliable, simple and optionally automatic mounting of the bottom plate, the retaining lugs extend transversely to the longitudinal direction of the flange and into the openings to hold the bottom plate against longitudinal and transverse displacements. A hook-shaped holding-down member is stamped out from the forward end portion of the carrying flange and extends into a recess provided in the front end face of the bottom plate, and the rear wall of the drawer is secured to the side walls and is arranged to hold down the bottom plate at its rear end portion, which extends under the rear wall.

  • Patent number: 5090786
    Abstract: A drawer having metal side walls comprises a bottom plate, which is supported on angled carrying flanges of the side walls. Each carrying flange has lanced retaining lugs, which are intended to extend into a groove of the bottom plate and after the bottom plate has been placed on the flange are adapted to be bent to assume a fixing position, in which the lugs extend into the material which constitutes one or both side faces of the groove. The retaining lugs are initially lanced to extend in the longitudinal direction of the flange and are adapted to be bent up transversely to the longitudinal direction of the flange and groove. Each lug has a root portion, which merges into the flange and is not wider than the groove. At a distance from the root portion the lugs are provided with lateral projections, which during the bending up of the lugs are in pressure contact with at least one side face of the groove and dig arcuate furrows into the side face.
