Patent ID: 7040725

Claim:
A telescoping slide assembly for supporting a movable drawer in a cabinet, the slide assembly comprising: an inner slide member affixed to a wall of the drawer, the inner slide member comprising a lengthwise channel including an outwardly projected lock pin; an outer slide member affixed to a wall of the cabinet, the outer slide member being smaller in cross-sectional area than the inner slide member such that the outer slide member can be received inside the inner slide member to allow a telescopic motion there between; a ball bearing retainer disposed between the outer and inner slide members for facilitating sliding of the inner slide member with respect to the outer slide member; and locking means disposed in a rear portion of the outer slide member and adopted to be received inside the inner slide member, the locking means comprising an elongate plate, a groove disposed on an inner surface of the plate, the groove including a shoulder at an intermediate narrow neck portion, a resilient member having one end affixed to a rear end of the groove, and an elongate sliding member having a rear end secured to the other end of the resilient member, the sliding member being slidable inside the groove and including a bottom stop surface, a top notch, and a front hook; wherein the sliding member and the front hook are constructed such that the rear end of the sliding member urges against the shoulder due to a compression of the resilient member, and the lock pin is retained by the front hook when the inner slide member is in a retracted position, the sliding member having a slanted rear portion which ends at the bottom stop surface, the sliding member further having a slanted front portion which pivots downward when the bottom stop surface of the sliding member is being pulled out of a mouth of the groove, causing the lock pin to be freed from the front hook and the bottom stop surface to abut the mouth of the groove, the top notch is disposed behind the front hook and is constructed to receive the lock pin and cause the slanted front portion to pivot upward and be received inside the groove when the inner slide member is being retracted, the top notch is further constructed such that it can retain the lock pin and cause the sliding member to be in motion with the lock pin when the inner sliding member is being pulled until the slanted front portion pivots downward thus releasing the lock pin from the top notch.
