Push button lock

A push button lock, comprising:

• a main housing with an aperture formed therethrough;
• a plunger which is axially moveable in the aperture of the main housing;
• a moveable stopper retainer positioned in the aperture of the main housing, the moveable stopper retainer having a central aperture formed therein through which the plunger extends, and a protrusion formed thereon;
• a plunger spring for biasing the plunger away from the moveable stopper retainer;
• at least one moveable stopper placed on the moveable stopper retainer;
• an actuator located in the main housing aperture above the moveable stopper retainer and rotatable to an open position, wherein the actuator is in position to be pushed down to prevent the at least one moveable stopper from moving away from the plunger shaft and thereby prevent the plunger shaft from moving relative to the moveable stopper retainer, and a locked position, wherein the at least one moveable stopper is not retained against the plunger shaft and the plunger shaft can move relative to the moveable stopper retainer;
• a lock button having a lock housing and a lock cylinder, the lock cylinder being adapted to turn the actuator from the opened position to the locked position;
• a moveable stopper retainer spring for biasing the moveable stopper retainer towards the lock button;
• and
• an actuator spring for biasing the actuator away from the moveable stopper retainer so that when the lock button is depressed in the locked or unlocked position, the plunger will not be capable of being pushed into main housing.

A push button lock, comprising:

• a main housing with an aperture formed therethrough;
• a plunger which is axially moveable in the aperture of the main housing and having a lock structure formed thereon;
• a ball retainer positioned in the main housing aperture and having a central aperture formed therein through which the plunger extends, and a protrusion formed on the moveable stopper retainer;
• a plunger spring for biasing the plunger away from the moveable stopper retainer;
• at least one ball placed on the ball retainer, the ball being adapted to seat against the lock structure on the plunger;
• an actuator located in the main housing aperture above the ball retainer and rotatable to an open position wherein the actuator is in position to be pushed down to prevent the at least one ball from moving away from the lock structure of the plunger shaft and thereby prevent the plunger shaft from moving relative to the ball retainer, and a locked position, wherein the at least one ball is not retained against the lock structure of the plunger shaft and the plunger shaft can move relative to the ball retainer;
• a lock button having a lock housing and a lock cylinder, the lock cylinder being adapted to turn the actuator from the opened position to the locked position;
• a ball retainer spring for biasing the ball retainer towards the lock button;
• and
• an actuator spring for biasing the actuator away from the ball retainer so that unless lock button is depressed in the unlocked position, the plunger will be capable of being pushed into main housing.
