摘要:
A core having a plurality of cutouts penetrating from the core surface to the keyway, and a plurality of activator inserts and filler inserts, such that the installer can locate one or more activator inserts in any of the cutouts, and one or more filler inserts in any of the remaining cutouts, to thereby define a program or code to be provided in the respective flank or flanks of an authorized key. At least three and preferably at least five slotted cutouts are provided. The inserts are preferably in the form of generally semi-circular plates on at least one side of the core. In various embodiments, the present invention is directed to a programmable cylinder lock system, a programmable core for a cylinder lock, a core kit by which the installer can program the core in the field, and a novel key adapted to be used with the programmable core.

The locking cylinder has a basic code which can be changed using at least one change key (17, 17′). A rotor (3) is mounted in a cylinder housing (2a, 2b) and has a keyway (4) into which a shank of a standard key which is provided with control surfaces 18 can be pushed in order to position the tumblers which are arranged in three first rows (A, B, C). Further tumblers have coding elements (13) which are arranged in further bores in the cylinder housing (2a, 2b) in a programming position of the rotor (3). The change key (17, 17′) interacts with three further rows (D, E, F) of tumblers in the programming position, these tumblers being arranged in slides. These further rows (D, E, F) each contain tumblers having coding elements (C). The locking cylinder can be produced with a smaller outside diameter and be installed in a particularly cost-effective manner.

The safety key has a shank (6) which is provided with a plurality of control surfaces (7) for properly positioning tumblers and has a front end and a rear end (6a, 6b). At a front end (4a), the rotor (4) of the associated locking cylinder (2) has at least one further control surface (8), which interacts with a further control surface (9) arranged at the rear end (6b) of the shank (5). The safety key is backward compatible and is relatively difficult to copy.

The lock cylinder assembly of the present invention incorporates a number of features designed to defeat attempts to pick or destroy the lock. The lock cylinder assembly employs multiple arrays of pass key pins, making picking of the lock much more difficult. Second, the arrangement of the pass key pins in separate arrays requires that multiple cuts would have to be made into the lock housing mogul or cylinder blank in order to defeat the lock cylinder assembly. Third, the lock cylinder assembly of the present invention may incorporate multiple sets of hardened dowel pins to prevent drilling through the lock housing mogul in the area of the driver pins. Fourth, the lock cylinder assembly of the present invention may incorporate a hardened cylinder shield behind the front face of the cylinder blank to prevent drilling through the cylinder blank.

An electromechanical cylinder lock-key combination includes a cylinder housing and a cylinder core rotatably arranged in the cylinder housing and having a key-way for receiving a key. A plurality of key actuated moveable blocking elements block the rotation of the cylinder core unless a correct key is inserted in the key-way. An optical code reader in the lock reads an optical code element provided on an inserted key. At least one of said blocking elements functions as a bar element barring insertion of the key into the key-way unless a correct optical code element is provided on the key. By using at least one of the mechanical elements already present in the lock as part of the electronically controlled blocking mechanism, in combination with the use of an optical code requiring no moveable parts for the reading thereof, space requirements in the lock device are kept to a minimum.
摘要:
A re-keyable lockset that employs pairs of first and second pins. Coupling of the first and second pins to one another defines a key profile for a mating key. A second key with a different key profile may be installed to the lockset when the first and second pins are uncoupled from one another. Thereafter, the first and second pins may be re-coupled to one another to define the key profile of a new mating key. A method for re-keying a lockset is also provided.
摘要:
A high security cylinder lock (1) and key (2) combination comprising a cylindrical shell (140), a key plug (130) which is rotatably mounted in the shell (140), a longitudinal key slot (100) in the key plug, and at least one locking tumbler assembly cooperating with a key being inserted into the lock. The locking tumbler assembly comprises a pair of independently movable tumbler segments (113, 114) which are positionable in different elevational positions in a common cavity.

A door lock set including a cylinder lock unit which has a lock shell and a plug is disclosed. The lock shell has an axially extending protrusion which projects outwardly and radially from an outer periphery of the lock shell and which has a plurality of pin holes that receive respective springs and tumbler pins. A cover is disposed over the protrusion to cover the pin holes and is biased outward by the springs. The cover is compressible against the springs to reduce the size of the lock shell so that the lock shell can be inserted easily into a rear shank of a knob of the door lock set for assembly. In a preferred embodiment, the cover has two opposite lateral sides extending over and engaging movably two opposite lateral faces of the protrusion. Methods for assembling and disassembling the door lock set are also disclosed.
摘要:
A re-keyable lock cylinder includes a plug body and a carrier sub-assembly disposed adjacent the plug body. The plug assembly includes a plurality of planar wafers and the carrier sub assembly includes a plurality of racks for engaging the wafers in a face-to-face teeth arrangement. The racks disengage from the wafers to separate the teeth in response to movement of the carrier such that the lock cylinder is in a re-keyable condition when the racks are disengaged from the wafers.
