摘要:
In a drawer guide with a guide rail to be fastened to the wall of a cabinet, the guide rail enters from below into a corresponding tubular runner rail of an open-bottomed rectangular or square cross section which is to be fastened removably to the drawer, and which contains in its interior races for rolling bodies held in an elongated cage. The rolling bodies can roll on the races of the guide rail on the one hand and on races formed by associated areas of the inner surface of the runner rail and thus permit a longitudinal movement of the runner rail relative to the guide rail, the rolling bodies that serve to accommodate the weight load being formed by a series of rollers with their horizontal axes disposed athwart the direction of drawer movement and the rolling bodies that serve for lateral guidance and stabilization being formed by two rows of balls disposed at a different level than the rollers, one on each side of the guide rail. The race provided for the rollers on the guide rail has a convexly curved cross section in order thus to permit the runner rail to be canted relative to the part of the guide rail provided in its interior.
