Corrugated three-piece drawer slide assembly

A low-cost, low-noise, and low-weight, high strength three-piece slide assembly is provided for use with cabinet drawers. The slide assembly includes a corrugated drawer-side member having a first corrugated surface with elongated corrugations having a first extending longitudinal axis parallel to the direction of drawer travel, and a cabinet-side member having a second corrugated surface with second corrugations extending parallel to the longitudinal axis. Also included is a corrugated intermediate member sized and shaped for sliding movement between the drawer-side and the cabinet-side members. The intermediate member includes a drawer-facing surface having third corrugations, and a cabinet-wall-facing surface having fourth corrugations. The third and fourth corrugations are respectively mateably engageable with the first and second corrugations. The third corrugations extend substantially equidistantly from opposite sides of a first medial plane and said fourth corrugations extend substantially equidistantly from opposite sides of a second medial plane, where the first and second medial planes are inclined with respect to each other. In an alternative embodiment, the intermediate piece is a steel element coated with a low coefficient of friction material and has a body with generally v-shaped corrugations sized and shaped for mateable sliding movement between similarly corrugated surfaces on the drawer-side and the cabinet-side members.
