ABSTRACT:
A mechanical push button lock including a lock bolt which is mechanically displaced to and from a locked position by the cooperative engagement of push button driven motion inducing means and bolt actuating means is disclosed. The motion inducing means is preferably formed as a conical element mounted to the inner end of each push button, and the bolt actuating means is preferably formed as a slide plate having a plurality of openings therein. The conical elements are skewed about their longitudinal axes so that axial advancement of the conical elements into the openings of the slide plate causes the slide plate to be preferentially displaced in a predetermined direction causing locking or unlocking of the lock mechanism. Means is also disclosed for spring biasing the push buttons and for operating the lock bolt independently of the push buttons.
