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.

1. 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;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 opened position, wherein the actuator can be pushed down to push the at least one moveable stopper against 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; anda 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, and the lock button being pushable into the main housing. 2. The push button lock of claim 1, further comprising a biasing means for biasing the actuator away from the moveable stopper retainer so that when the lock button is depressed when in the unlocked or unlocked position, the plunger will not be capable of being moved into the main housing. 3. The push button lock of claim 1, further comprising biasing means for providing spring loading of the plunger relative to the moveable stopper retainer. 4. The push button lock of claim 1, further comprising biasing means for providing spring loading of the moveable stopper retainer relative to the lock housing. 5. The push button lock of claim 1, further comprising anti-rotation means to prevent rotation of the lock housing and moveable stopper retainer relative to the main housing. 6. The push button lock of claim 1, wherein the moveable stopper comprises at least one ball. 7. The push button lock of claim 1, wherein the protrusion on the moveable stopper comprises at least one moveable stopper lobe with a notch formed thereon and the actuator has at least one block formed thereon which is sized to be seatable with the notch when in the opened position, and the actuator has at least one ramp formed thereon which will impinge on the moveable stopper lobe when in the locked position. 8. The push button lock of claim 1, further comprising a plunger button fixed to a distal end of the plunger. 9. The push button lock of claim 1, wherein the plunger has a plunger rim against which the at least one moveable stopper may impinge when the actuator is in the opened position and the lock button is pushed into the main housing. 10. The push button lock of claim 1, wherein the lock cylinder is a key lock. 11. The push button lock of claim 1, wherein the plunger shaft further comprises a plunger rim extending outwardly from the plunger shaft. 12. 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; andan 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. 13. The push button lock of claim 12, further comprising anti-rotation means to prevent rotation of the lock housing and moveable stopper retainer relative to the main housing. 14. The push button lock of claim 12, wherein the moveable stopper comprises a ball. 15. The push button lock of claim 12, wherein the at least one moveable stopper lobe has a notch formed thereon and the actuator has at least one block formed thereon which is sized to be seatable with the notch when in the open position and with the lock button pushed to thereby force the moveable stopper into contact with the plunger, and the actuator has at least one ramp formed thereon which will impinge on the moveable stopper lobe when in the opened position to permit the moveable stopper to move away from the plunger even when the lock button is pushed. 16. The push button lock of claim 12, further comprising a plunger button fixed to the distal end of the plunger. 17. The push button lock of claim 12, wherein the lock cylinder is a key lock. 18. The push button lock of claim 12, wherein the plunger shaft further comprises a plunger rim extending outwardly from the plunger shaft. 19.
