The lock sleeve provides disposition and combination of the revolver and includes some pin holes providing disposition of upper pinballs, springs and a stop pin. The revolver includes a key channel for insertion of a key and some pin holes providing disposition of lower pinballs. Additionally, the main body of the revolver is made of two different metallic materials combined together, where the front part of it is made of easily machined cast iron or copper and the rear part of it is made of steel material or heat treatment reinforced steel which has more structure strength. Furthermore, a gate room is formed beside an open end of the key channel and provides disposition of a gate and a spring, which is sealed and fixed by a keyhole cover. The gate is constantly pushed by the spring and moves upward to seal the open end of the key channel.

Multi-piece plug assembly for a cylinder lock

A cylinder lock assembly includes a cylinder body and a plug assembly which is manufactured in a multiple of pieces to facilitate casting of each plug piece in a single operation. The plug assembly includes a plug body with a plug insert opening to receive a plug insert. The plug insert opening is generally L-shaped in cross-section to receive the plug insert which is correspondingly shaped. The plug insert includes a plug outer portion which defines an arcuate outer surface which corresponds with the outer circumference of the plug body when the plug insert is mounted therein. A plug pin chamber portion extends generally transverse to the plug outer portion to define a multiple of tumbler pin chambers which extend through the plug outer portion.

Key plug for a key-programmable cylinder lock and key-removable lock core

A plug assembly for use in a key-operated lock, having a cylindrical key plug that can rotatable between a key insertion position and a control position, the key plug having a keyway and tumbler bores, an axial groove into the periphery displaced tangentially from the tumbler bores, a curved trough extending radially inwardly from the carriage groove, a control tooling slot formed radially inwardly from the curved trough. A carriage is moveable axially within the carriage groove, and has an outer surface proximate with the cylindrical periphery of the key plug. The carriage has radially-formed retainer bores that align tangentially with the tumbler bores when the carriage is in a position to accept lock configuration change balls. A separate change tooling blade can be inserted into the control tooling slot to raise any change balls within the retainer bores out through an outer opening the retainer bore.

Lock device based on a mechanically re-programmable disc-type device and key for the same

A cylinder and key lock mechanism is unlocked when a specific combination of rotation angles of dialer groups, each constituted by one internal dialer disc and by one external dialer ring coupled through teeth, is dialed through rotation of the key having a formed cipher. A security mechanism, being part of the key and driven by the insertion of the key into the cylinder, enables re-programming. When unlocked and with re-programming enabled, re-programming is possible where the inner dialer discs are decoupled from the respective outer dialer rings, the key can be rotated driving only the inner dialer discs and extracted leaving the system in a re-programming configuration. A new key having a different cipher can be inserted and the system exited re-programming with a different coupling between the inner dialer discs and the respective outer dialer rings so that they couple with the new key cipher.

A safety apparatvs for locker and an unlocking key therefor

PURPOSE: A safety system of a cylinder lock and a key thereof are provided not to be released by a usual key by mounting a safety pin perpendicularly to a plurality of driven pins and a lock pin to operate under the elasticity of the safety pin in the cylinder lock, thereby preventing the burglary in advance. CONSTITUTION: In a safety system of a cylinder lock, which is formed with a plurality of through holes(4) formed at a side for inserting a plurality of drive pins(3) by a spring(2) and a through hole(101) in the center longitudinally for inserting a rotation element(120), a main body(100) of the cylinder lock is formed with a single through hole(114) perpendicularly to the plurality of through holes for inserting a safety pin(110) and a spring(112), and the rotation element is formed with a through hole(124) having a protrusion for inserting a lock pin(122) which operates under the elasticity of the safety pin. A key for releasing the cylinder lock mounted with the safety pin and the lock pin is mounted with balls(131,132) and springs(133,134) at both sides thereof.
