Abstract

Abstract On a drawer guide having a guide track to be fastened to the carcase of a cabinet and a runner track to be fastened to a drawer side, the drawer or other sliding device is movable relative to the cabinet by at least one wheel journaled at the front end of the guide track and at least one wheel journaled at the rearward end of the runner rail, each wheel rolling against a flange on the opposite rail. A circumferential groove is provided on each of the rolling surfaces of the wheels, and in it there is inserted a resilient tire of rubber, plastic or other elastomeric material, which then protrudes above the rolling surface of the wheel. In the end portions of the tracks, at the points where the wheels are at rest when the drawer guide is fully retracted, an indentation or groove of short length is provided in alignment with the resilient tire, and the depth thereof is at least equal to the height of the resilient tire above the rolling surface of the wheel.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 211 words
A guide for a drawable cabinet part, comprising: an elongated guide rail for fastening to a cabinet carcase, and having a front end and a rear end, and a flange; an elongated runner rail for fastening to a drawable cabinet part, and having a front end and a rear end, and also having a flange; said rails being displaceable relative to one another on first roller means rotatably mounted on the front end of the guide rail and rolling on the flange of the runner rail, and on second roller means rotatably mounted on the rear end of the runner rail and rolling on the flange of the guide rail; at least one circumferential groove in each roller surface of the roller means, a resilient tire inserted respectively into said roller means and protruding slightly above the rolling surface, end sections of the track flanges supported on the rolling surfaces of the respective roller means in fully retracted position of the tracks having a narrow indentation in alignment with the respective resilient tire and extending a short distance in the opening direction of the drawer, the depth of the indentation being at least equal to the radial elevation of the resilient tire above the rolling surface of the respective roller means.
Claim 2
Dependent Claim 211 words
A guide for a drawable cabinet part, comprising: an elongated guide rail for fastening to a cabinet carcase, and having a front end and a rear end, and a flange; an elongated runner rail for fastening to a drawable cabinet part, and having a front end and a rear end, and also having a flange; said rails being displaceable relative to one another on first roller means rotatably mounted on the front end of the guide rail and rolling on the flange of the runner rail, and on second roller means rotatably mounted on the rear end of the runner rail and rolling on the flange of the guide rail; at least one circumferential groove in each roller surface of the roller means, a resilient tire inserted respectively into said roller means and protruding slightly above the rolling surface, end sections of the track flanges supported on the rolling surfaces of the respective roller means in fully retracted position of the tracks having a narrow indentation in alignment with the respective resilient tire and extending a short distance in the opening direction of the drawer, the depth of the indentation being at least equal to the radial elevation of the resilient tire above the rolling surface of the respective roller means.
Claim 3
Dependent Claim 75 words
A guide according to claim 1, wherein a further narrow indentation extending a short distance in the drawer opening direction and having a depth at least equal to the radial elevation of the resilient tire above the rolling surface of the respective roller means is provided in alignment with the resilient tire in end sections of the flanges resting on the rolling surfaces of the roller means when the tracks are in fully extended position.
