Locker lock

DETAILED DESCRIPTION In accordance with the present invention, a combination locker lock for mounting to the door of a storage locker is provided.
The lock has a case and a bolt extending therefrom for engaging behind a strike in the locker frame.
This bolt acts both as a spring loaded bolt and a dead bolt.
To accomplish this dual functionality, the bolt has two extension positions, a fully extended position where the bolt acts like a dead bolt and a partially extended position where the bolt acts like a spring loaded bolt.
The bolt can only be moved inward from its fully extended position upon entering the proper combination and rotating the combination dial.
The two extension positions also enable greater bolt extension from the lock without requiring increased bolt thickness in order to accommodate a full-face taper.
When the bolt is in the partially extended position and the locker door is closed, the strike will push against a tapered surface on the bolt, pushing in the bolt into the case.
A plunger associated with the bolt will also be pushed into the case.
When the bolt passes the strike it will begin to extend from the case; however, the plunger, because of its positioning relative to the bolt, will contact the strike and will not extend from the case with the bolt.
This induces relative motion between the plunger and the bolt, which permits the bolt to move to the fully extended position.
A single trigger mechanism associated with the bolt and the plunger is used to hold the bolt in the spring loaded position, to secure the bolt in the dead bolt position, and to release the bolt to the fully extended position.
The combination lock can be quickly and easily flipped 180.
degree.
for both right and left hand locker door applications while maintaining the same set of combinations.
The lock has a case with integral mounting flanges and a relieved edge adjacent the edge of the door, to permit the combination lock to be placed as close to the strike as possible even in narrow door applications
