Patent number: 7920048Abstract: A container has a lid and a locking mechanism. The locking mechanism includes a male wall with a switch. A female wall mounts to the inside wall of the container and, when closed, encompasses the male wall. The female wall has a magnet that activates the switch. A lever contained inside the male wall moves into and out of a slot formed in the female wall. The switch completes a circuit that generates a close signal to the lever when the lid is closed. A button extends through a hole in the lid such that the button can be depressed to indicate locking and cannot be depressed when unlocked. When unlocked, the button cannot be depressed because the lever blocks the button. To open the container when closed, the actuation mechanism moves the lever in response to an entered code that must match a stored code or calculated content-specific code.Type: GrantFiled: May 9, 2006Date of Patent: April 5, 2011Inventors: John W.

Patent number: 7647797Abstract: A programmable electronic lock with a closing tongue is actuated with an actuating mechanism formed by a mobile knob acting as a button joined to the closing tongue. Actuation of the mobile knob generates a movement of the closing tongue and closure of the lock. Recovery of the mobile knob to its initial position generates an opening of the lock. Furthermore, an electronics board is activated with a transponder key and controls operation of the lock by deactivating and subsequently activating a blocking mechanism formed by a motor that actuates a punch via a gear mechanism. When the punch is in a blocking position it is located against the actuating mechanism. When the punch is in an unblocking position, it is separated from the actuating mechanism and allows the movement of the closing tongue by unblocking the actuating mechanism.Type: GrantFiled: July 24, 2008Date of Patent: January 19, 2010Assignee: Ojmar S.A.Inventors: Ana Viso Cabrera, Ramón Gabikagogeaskoa Sanchez, Beatriz Vierna Garcia

Publication number: 20090165512Abstract: An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes an actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. In an unlocked state, the actuator moves the tumbler blocking member so that a movable locking member in the rotatable core that engages the outer body can be moved into the rotatable core. In a locked state, the actuator positions the tumbler blocking member to prevent the one or more tumblers from retracting and thereby retain the locking member in a channel of the outer body.Type: ApplicationFiled: December 27, 2007Publication date: July 2, 2009Inventor: Dirk L.

Patent number: 7520152Abstract: A door lock device includes a lock having a deadbolt with a first end and a second end. The second end is structured to disengage from an object, such as a portion of a door frame, in a first position and to engage the object in a second position. A spring directly engages and biases the first end of the deadbolt toward the second position thereof. A solenoid includes a plunger structured to engage the deadbolt, in order to hold the deadbolt in the first position thereof. A sensor is structured to sense at least one of the first and second positions of the deadbolt. A wireless controller is structured to receive a wireless signal and responsively energize the solenoid, in order to disengage the plunger of the solenoid from the deadbolt and release the deadbolt to the second position thereof.Type: GrantFiled: September 13, 2005Date of Patent: April 21, 2009Assignee: Eaton CorporationInventors: Russ C.

Publication number: 20090007613Abstract: Disclosed is a rotary lock cylinder comprising a blocking element (25, 64) that engages into the rotor (10) in a closed position while releasing the rotor (10) in an open position. An actuator (17, 78) can be controlled in accordance with data located on the key (2). In order to displace the blocking element (25, 64) from the closed position into the open position, a latch element (33, 63) is provided which can be moved along with the key (2). The blocking element (25, 64) can be attached by means of the actuator (17). The energy required for moving the blocking element (25) is supplied by the user when introducing the key (2) into the key duct (11) such that the load on the power source used for actuating the actuator (17, 78) is minimal.Type: ApplicationFiled: December 13, 2006Publication date: January 8, 2009Applicant: Keso AGInventors: Martin Spycher, Urs Oechslin, Bruno Vonlanthen, Marcel Kolliker, Dieter Peier

Patent number: 7469564Abstract: Described herein is a locking device and method which integrates mechanical components in a hollow metal door frame with electronic access components. The electronic components override the original mechanical components of the lock to create a fail-safe situation in which the original mechanical lock may be disabled. In the preferred embodiment, my upgraded locking device can be re-installed within a hollow door frame, thereby minimizing service costs and doorframe modification costs. The electronically controlled component can be a cam retaining locking bar which contains a roll pin and an open area bordered by two cut sides. The open space eases lock installation with a door by avoiding protruding door structures such as metal tabs.Type: GrantFiled: December 15, 2004Date of Patent: December 30, 2008Inventor: Barry M.

Patent number: 7406846Abstract: An electronic lock incorporating one or more shape memory metal wire segment as its electromechanical transducer. An electronic control circuit injects electrical current into the shape memory metal wire, causing it to heat up and contract. A gate is positioned by the action of the shape memory metal wire(s) to either allow or block the movement of a locking bolt that affect locking or unlocking. Millions of operational cycles are achieved by limiting the stretching of the shape memory metal wire at low temperature to small percentages of its total length. The design lends itself to miniaturization, with commensurate reduction in power consumption, that is useful to the evolution of future electronic locks.Type: GrantFiled: May 11, 2005Date of Patent: August 5, 2008Assignee: Nanotechnology, Inc.Inventor: John Wun-Sing Chu
