ABSTRACT:
The specification discloses a drawer slide assembly providing automatic centering of the drawer within the cabinet opening and enabling a drawer of increased dimensions to be utilized in a given cabinet opening. The assembly includes a pair of cabinet channels secured to the cabinet and a pair of drawer rails secured to the drawer. The drawer rails ride on cabinet rollers supported at the forward ends of the channels. The cabinet rollers are mounted on an axis below the cabinet opening and are frustoconically shaped to cooperate with beveled surfaces on the drawer rails to guide the drawer to a centered position. The cabinet rollers, drawer rails, and drawer are vertically aligned so that the drawer can extend the full width of the opening. The rear ends of the cabinet channels are forked and extend into apertures in the cabinet rear wall to support the channels in the cabinet. A pair of drawer rollers ride in the channels and are supported at the rear of the drawer on drawer corner brackets fabricated from a single sheet of material folded upon itself to provide a strong roller supporting portion. Each channel includes a lateral guide wall inclined from the vertical to reduce frictional contact of the drawer rollers therewith.
