PUSH-BUTTON LOCK ARRANGEMENT

摘要

The push-button lock arrangement includes a permutation chamber (5). The combination of the permutation chamber can be changed without dismantling the lock arrangement and without the use of special tools. A cam (85) 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 (41) and a stationary stopper (45). The rotating stop member is connected to the outside door knob so that the rotation of the outside door knob (17) is constrained to a predetermined angle of rotation.
