Lock cylinder, has rotating shaft of pinion extends along central longitudinal axis across opening, where pinion and rotating shaft are connected in rotation by complementary form

摘要

The cylinder has a body (3) being in an opening, and a pinion (5) to drive each bolt of a lock through a displacement mechanism. A rotating shaft (7) of the pinion extends along a central longitudinal axis across the opening. Two buttons (9, 11) manipulates the rotating shaft. The pinion and rotating shaft are connected in rotation by a complementary form (35). An Independent claim is also included for a lock with a lock cylinder.
