ABSTRACT:
A cabinet drawer is provided with two drawer supports or rollers which are mounted near the front edge of the cabinet which supports the drawer, and below the edges of the drawer. The roller or support assembly includes a roller which is relatively flat and is mounted to rotate about an axis which is tilted inward toward the drawer by about 12 degrees. The upper surface of the roller is a relatively flat cone, and the roller rotates with the drawer in engagement with the horizontally extending outer portion of the upper conical surface of the roller. The support makes engagement with the lower surface of the flat roller, and is also provided with tabs for securing the roller assembly to the cabinet. The roller and its housing or support are held together by an axial member which may be a part of the roller, a part of the support, or a separate securing fastener. The roller and its housing should be of material having good wear qualities and low relative friction; for example, the roller may be of acetal resin, and the housing may be of high density polyethylene. Ball bearings may be provided between the roller and the housing; and the roller may be held in position by several retaining elements.
