A method for coupling two rotating parts of a cylinder lock has spring loaded plungers whose action is inhibited by a central shaft

摘要

The lock is released by rotating a first cylinder (10) by a second rotating part (6) with the plungers (20) prevented from moving by a central shaft (15) having two flats (18) diametrically opposite each other. A 90 degree rotation of the shaft by a motor allows the plungers to ride over cams (24').
