Document Type and Number:
Japanese Patent JPS5565677
Kind Code:
A
Abstract:
A cylinder lock comprising a cylinder housing and therein a turnable cylinder enclosing a plurality of tumbler discs turnable by means of the key of the lock. Between the cylinder housing and the peripheral edges of the tumbler discs, there is a locking bar locking the cylinder to the cylinder housing. This bar is movable from a position locking the cylinder, in which position it is located partly in a groove in the internal wall of the cylinder housing, to a position releasing the cylinder by entering a channel formed jointly by notches in the peripheral edges of the tumbler discs when the discs are turned to a certain position. The movement of the locking bar is laterally guided by means of guiding discs, at least substantially non-rotatably fitted with respect to the cylinder. When the lock mechanism is fully released, the turning force transmitted by the key of the lock, is transmitted from the key to a tumbler disc, therefrom to the locking bar and from the locking bar to the guiding discs and through them to the cylinder.
