ABSTRACT:
A lock set comprises a housing having a latch bolt assembly supported therewithin. The bolt assembly includes a bolt movable between latched and retracted positions. A retractor slide is connected to the bolt and is supported by the housing for longitudinal sliding movement relative thereto between bolt retracted and latching positions. Axially movable and rotatable first drive member extends transversely of the direction of movement of the bolt and is engaged with the retractor slide for movement thereof between the bolt retracted and latched positions. The first drive member includes a locking surface. An operating assembly comprises a hand operator having a locking slot formed in an axially extending portion thereof. A cylinder having a plug portion is disposed within the hand operator, the plug portion being rotatable relative thereto. A non-rotatable sleeve is radially sandwiched between the hand operator and the first drive member and includes a radially movable retainer aligned with the locking slot and normally extending therethrough for locking the hand operator to the sleeve. The locking surface of the first drive member is radially aligned with the retainer for maintaining the retainer within the slot. A second drive member is operatively connected to the rotatable plug and to the first drive member. Rotation of the plug results in actuation of the second drive member to move the first drive member axially to radially displace the locking surface relative to the retainer member.
