Each of a pair of drawer channel members is affixed to a correspondong side of a drawer having spaced opposite sides and opens outward toward a frame having a chamber therein accommodating the drawer and having spaced opposite sides, the sides being parallel. Each of a pair of frame channel members is affixed to a corresponding side of the frame in the chamber and opens inward toward the drawer and is positioned adjacent the corresponding drawer channel member. The channel members are positioned parallel. Each of a pair of extension bars is slidably positioned between a corresponding one of the drawer channel members and the adjacent frame channel member. Each of the channel members and each of the extension bars is shaped in a manner whereby each of the extension bars restrains, or is restrained by, the corresponding drawer channel member and frame channel member in sliding next-adjacent relation. Bores are formed through the extension bars. Rollers are rotatably mounted in the bores through the extension bars at predetermined angles of inclination with the sides of the drawer and the chamber of the frame. The rollers extend beyond the bars. Each of the rollers abuts and rolls on part of a drawer channel member and part of the corresponding frame channel member. The drawer and/or frame channel members may be tool-worked or molded right into position instead of constituting separate parts, or they may be provided with tabs, flanges, mounting holes, kerfs, grooves, or the like, for ease of assembly to said drawer and/or frame, and such assembly facilitating features may also serve as means to simplify and strengthen construction, assembly and fastening of elements of said drawer and frame. Furthermore, the drawer and frame relative sliding arrangement may be applied to any mechanically similar applicaton, not otherwise resembling exactly the features described herein.
