Patent number: 8051689Abstract: A cylindrical lock includes inner and outer chassis, inner and outer spindles, and first and second actuating members. One of the first and second actuating members is selectively and rotatably received in the outer spindle. Each of the first and second actuating members includes a limiting groove having first and second groove sections with different arcs in a circumferential direction about a longitudinal axis. A driving member is rotatably received in one of the first and second actuating members. The driving member has a leg movable in the outer spindle between first and second positions along the longitudinal axis and received in one of the first and second groove sections. A driving device is received in the inner spindle. The cylindrical lock has two modes corresponding to selective use of the first and second actuating members to provide locking/unlocking states through supply or not supply of electricity to the driving device.Type: GrantFiled: November 11, 2010Date of Patent: November 8, 2011Assignee: I-Tek Metal Mfg. Co., Ltd.Inventors: Chun-Meng Shen, Wei-Chung Hsu

Patent number: 8047031Abstract: An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes a piezo-electric actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. Tamper circuitry coupled with the piezo-electric actuator is configured to resist an externally induced acceleration of the electronic lock by shunting electrical power produced by an externally induced motion of the piezo-electric actuator back to the piezo-electric actuator.Type: GrantFiled: December 27, 2007Date of Patent: November 1, 2011Assignee: UTC Fire & Security Americas Corporation, Inc.Inventors: Dirk L. Bellamy, Charles E. Seeley

Publication number: 20110259062Abstract: Disclosed is a rotary lock cylinder including a blocking element that engages into the rotor in a closed position while releasing the rotor in an open position. An actuator can be controlled in accordance with data located on the key. In order to displace the blocking element from the closed position into the open position, a latch element is provided which can be moved along with the key. The blocking element can be attached by means of the actuator. The energy required for moving the blocking element is supplied by the user when introducing the key into the key duct such that the load on the power source used for actuating the actuator is minimal.Type: ApplicationFiled: May 6, 2011Publication date: October 27, 2011Applicant: Keso AGInventors: Martin Spycher, Urs Oechslin, Bruno Vonlanthen, Marcel Kölliker, Dieter Peier

Patent number: 8033147Abstract: An electronically controlled lock with a single throw acting as a passage lock and also as a deadbolt lock is provided by the invention. The lock is equipped with an electronic activation device on its exterior housing and a door lever on its internal housing. A user unlocks the door from outside by touching an electronic key against the electronic activation device. After the door is unlocked, the throw acts as a passage lock. The door can be locked internally by moving the door lever from a horizontal position upwardly to a vertical position.Type: GrantFiled: February 18, 2010Date of Patent: October 11, 2011Assignee: HandyTrac Systems, LLCInventors: John Lie-Nielsen, Tibor Szenti

Patent number: 8028553Abstract: A lock cylinder with a lock cylinder housing is provided. A knob shaft, rotatable by way of a knob, is mounted to rotate on one side or both sides of the lock cylinder. An authorization signal causes at least one electromechanically operating coupling device to connect a lock element to rotate in unison with the knob shaft and in order to operate a lock. The authorization signal is generated by evaluation electronics based on an input or input signal. It is proposed that at least one reading unit with an input unit to record the input and/or a receiving unit to receive the input signal is present, that the reading unit with the input unit and/or receiving unit is arranged in at least one knob and are spatially separated from the evaluation electronics, that the knob is connected electrically and mechanically releasable to the knob shaft, and that the reading unit generates, from the input or input signal, an access signal that can be evaluated by the evaluation electronics.Type: GrantFiled: June 15, 2006Date of Patent: October 4, 2011Assignee: ASSA Abloy ABInventor: Volker Lange

Patent number: 8011217Abstract: The present invention provides for a handle set for a lock with a latch, the handle set having an authentication circuit and actuator in the interior handle that allow access to authenticated transponders. The present invention also provides a device and method for transmitting a rotational movement and force in an electronic lock, wherein the transmission takes place in a coupled state and not in a decoupled state and wherein the transmission of force does not damage an actuator that requires little energy to change between the coupled and decoupled states. The handle set can include a coupling cartridge that can be easily handed. The electronic lock can be retrofitted in installed mortise locks and used with cylindrical locks. The electronic lock can include a security feature that prohibits the electronic lock from changing between the coupled and decoupled states.Type: GrantFiled: April 4, 2007Date of Patent: September 6, 2011Assignee: SimonsVoss Technologies AGInventors: James S Marschalek, Warren A.
