ABSTRACT:
A drawer slide has a pin and torsion spring lock (28) for securing an intermediate slide member (16) relative to a cabinet member (18). A lock pin (154) has a head (180) and a shank (178). A groove (182) is formed into the shank (178). A torsion spring (156) is secured to the intermediate slide member (14) and engages the groove (182) to urge the lock pin (154) into a first position within a slot (158) formed in the intermediate slide member (16). The head (180) of the lock pin (154) extends on an opposite side of the intermediate slide member (16) from the torsion spring (156). Two stops (162, 164) are disposed on the cabinet slide member (18) for engaging with the head (180) of the lock pin (154). A release member (172) is embossed in the web portion (44) of the chassis member (14).
