Abstract
Abstract A drawer runner comprises a mounting member adapted to be mounted in a cabinet in which a drawer is to be supported in use, a pair of spaced bearing members mounted on the mounting member for engagement in the runner recess in the drawer side, and a fixed load-supporting member carried by the mounting member and adapted to assist in supporting the weight of the drawer when the drawer is laden and in its closed position. The bearing members may comprise rollers rotatably mounted on studs carried by the mounting member, the load-supporting member comprising a flange disposed rearwardly of the rear bearing member or disposed beneath the bearing members and arranged to be contacted by the drawer only when the latter is closed and laden.
