A locking mechanism for furniture unit is provided which utilizes a single component for translating rotary motion of a tumbler cylinder of a key lock into reciprocating, linear motion of a pair of opposing lock rods. The mechanism includes a base having a pair of linear guide channels which are defined by spaced sidewalls, a lock rod received in each of the linear guide channels, each of the lock rods having a radially extending projection engaging the sidewalls of one of the guide channels, a key lock, and an actuator which is attached to a drive shaft connected to the tumbler cylinder of the key lock. The actuator includes a pair of arcuate channels, each of which is at least partially defined by spaced camming surfaces which engage opposing sides of the projections on the lock rods, whereby rotation of the actuator in one direction retracts the rods to the unlocked position and rotation in the opposite direction extends the rods to the locked position. A lockable furniture unit employing a locking mechanism having a base, a pair of lock rods, a key lock, and an actuator which has arcuate camming surfaces which facilitate translation of rotary motion of the tumbler cylinder of the key lock into linear motion of the lock rods is also disclosed.

A lockable furniture unit, comprising: a plurality of stationary wall panels and at least one closure member which together define a substantially continuous storage enclosure; and a locking mechanism, said locking mechanism including a base mounted onto an interior side of said at least one closure member of the furniture unit, said base including a pair of integral linear guide channels, each guide channel being at least partially defined by spaced sidewalls; a lock rod received in each of said linear guide channels, each of said lock rods having a radially extending projecting engaging said spaced sidewalls; a key lock having a stationary barrel fixedly attached to said base, and a lock tumbler cylinder mounted within said stationary barrel for rotation between a locked position and an unlocked position; and an actuator fixedly attached to a drive shaft connected to said tumbler cylinder, said actuator including a pair of arcuate channels, each of which is at least partially defined by spaced camming surfaces which engage opposing sides of one of said projections of lock rods, whereby rotation of said actuator urges said rods toward a rotational axis of said tumbler cylinder and counter-rotation of said actuator urges said rods away from the rotational axis of said tumbler cylinder, and said base further comprising cantilever springs having a stop element disposed thereon, and said actuator further comprising at least one projection which is engaged by one of said springs and by said stop element disposed thereon to maintain the lock in an unlocked or locked position when the tumbler is fully rotated to said unlocked or locked position.
