Title:
CYLINDER LOCK
Document Type and Number:
Japanese Patent JPS5998982
Kind Code:
A
Abstract:
A cylinder lock having a plurality of plate-like tumblers, each of which is carried by the lock barrel to rotate therewith and each being adapted to locate within a respective locking recess provided in the lock body and thereby hold the barrel against rotation relative to the body. The tumbler plates are movable laterally relative to the barrel axis so as to be capable of removal from their respective locking recesses and thereby free the barrel for rotation. A locking pin interconnects the tumbler plates so that they move in unison between their barrel locking and release positions, and a plurality of rotatable discs interacts with that pin to control its ability to move radially inwards and thereby free the tumbler plates from their locking recesses. Each disc has a peripheral notch which must be located adjacent the locking pin to allow the aforementioned radial inward movement.
