ABSTRACT:
A multi-member drawer slide automatically latches in both the fully extended end fully unextended positions. A largest, first, linear member is affixed to a cabinet; second and third intermediate linear members slide on ball bearings within the linear channel of next larger members; and a smallest, fourth, linear member slides frictionally within a linear channel of the third member and is affixed to a drawer. A latch frame affixed to the channel of the third member extends transversely to the members to a position exterior the first member's side. A pivot bar pivotably maintained on this latch frame selectively engages the first members's end, thereby holding the second and third members fully extended. In one embodiment this same pivot bar engages the first member's other end to maintain all members fully unextended. In another embodiment another latch is mounted to the first member's side and engages a fourth member end flange to hold all members fully unextended. A final latch retains the fourth member within the third member's channel.
