Abstract

A lock for furniture includes a plunger assembly for actuating a lock mechanism. The plunger assembly includes a reader for receiving a control signal from a key. The plunger assembly includes a curved surface for contacting a lock rod such that the plunger assembly requires a constant force to move the lock rod through its range of motion to a locked position. A catch assembly secures the plunger, and hence the lock rod, in a locked position. A solenoid shifts the catch assembly to release the plunger assembly. The lock assembly may also include a lever connected at one end to the catch assembly and having a counterweight on an opposite end.
