ABSTRACT:
The push-button lock arrangement includes a permutation chamber, and, in accordance with the invention, the combination of the permutation chamber can be changed without dismantling the lock arrangement and without the use of special tools. A cam, which is rotated by a simple screwdriver, activates the end of the lock-out slide of the permutation chamber to put the permutation chamber in its reset mode. The lock arrangement also includes a rotating stop member and a stationary stopper. The rotating stop member is connected to the outside door knob so that the rotation of the outside door knob is constrained to a predetermined angle of rotation.
