Abstract
Abstract A drawer for cupboards comprises a baseplate (10) guided displaceably in lateral guide rails, a frame (14) surrounding the baseplate at its lateral and rear edges, and an adjustable front plate (12) closing the drawer off at the front. Simple adjustment of the front plate (12), without prior dismantling of individual parts, becomes possible because the frame (14) is designed as a self-supporting part to be fastened to the baseplate (10), and because devices (30, 32) for the adjustable fastening of the front plate are provided at the ends of the frame (14) which face the front plate. This ensures, at the same time, that the frame, including the fastening and adjusting devices for the front plate forms together with the remaining parts (10, 12) of the drawer a smooth-surface structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
243 words
A drawer for cupboards, particularly a drawer for pots, comprising: a baseplate having lateral and rear edges; a front plate having an inner face and two sides; a frame projecting vertically upwards and surrounding the baseplate at the lateral and rear edges, said frame being a self supporting part to be fastened to the baseplate and having an open side and two ends facing the front plate on the open side of the frame, said ends forming supports for the adjustable fastening of said front plate; at each side of said front plate, an essentially vertical fastening strip attached to the inner face of the front plate, the frame having a hollow structure which engages the fastening strip, the fastening strip having a projection which is received in the hollow structure and which includes a recess which is open at the bottom and which surrounds at a distance a clamping screw extending transversely through the hollow structure to clamp the hollow structure to said fastening strip and to allow vertical and tilting adjustment of the front plate in relation to the base plate, a sliding piece clamped in the hollow structure in the end of the frame which faces the front plate, and wherein the fastening strip slidably engages the sliding piece in the lower region of the frame, via a play-free guide extending transversely to the pull-out direction of the drawer; and means for locking the fastening strip on the sliding piece.
