Abstract: A chassis lock (32) for drawer slide (12) is provided by a slot (20) and a rotary lock member (34). The rotary lock member (34) has a disk-shaped body (36) with an arcuately shaped cutout portion defining a cam follower surface (38). A stop protuberance (42) extends from the rotary lock member (34) with opposite ends (47, 49) which locate the rotary lock member (34) in an open position and a closed position. A torsion spring (50) urges the rotary lock member (34) into the closed position. The weight of a drawer is applied through a mounting lug (30) to the cam follower surface (38), to move the rotary lock member (34) to the open position which aligns the cam follower surface (38) for passing the mounting lug (30) into a lock section (26) of the slot (20). When in the closed position, the disk-shaped portion (36) of the rotary lock member (34) prevents removal of the mounting lug (30) from within the lock section (26) of the slot (20).
