Abstract
A push button lock. The push button lock has a main housing with an aperture formed therethrough, a plunger which is axially moveable in the aperture of the main housing, and a ball retainer positioned in the aperture of the main housing. The ball retainer has a central aperture formed therein through which the plunger extends and a protrusion. Balls are placed on the ball retainer. An actuator is located in the main housing aperture above the ball retainer and is rotatable to an open position, wherein the actuator is in position to be pushed down to prevent the balls from moving away from the plunger shaft and thereby prevent the plunger shaft from moving relative to the ball retainer, and a locked position, wherein the balls are not retained against the plunger shaft and the plunger shaft can move relative to the balls retainer. A lock button having a lock housing and a lock cylinder is provided, with the lock cylinder being adapted to turn the actuator from the opened position to the locked position.
