Description

1 DRAWER LOCK ASSEMBLIES TECHNICAL FIELD

[0001] The present disclosure relates generally to lock mechanisms, and more particularly, to drawer lock assemblies for use with cabinet drawers, desk drawers and the like. BACKGROUND

[0002] Numerous types of core cylinders for locks are known and popularly used for various applications. In one application, a lock is provided to secure a drawer of a cabinet, desk or similar structure. In such application, a lock assembly is mounted through a hole or aperture of a drawer, and thus moves with the drawer when opened or closed. When the drawer is in a closed position, a bolt or latch projects from the lock assembly into an aperture, recess or other portion of the structure to secure the drawer in the closed position. To open the drawer, an appropriate key is inserted into the core cylinder and rotated to withdraw the bolt or latch into the lock assembly and from the portion of the structure, enabling the drawer to be opened.
