  • Patent number: 8522583
    Abstract: In one aspect, the invention is directed to a closure latch for a vehicle door. The closure latch includes an emergency lock actuator to permit a person to lock the door in the event that the power lock actuator is unusable. The latch also includes an ‘impatient passenger’ feature, which permits the doors to be unlocked using the remote keyless-entry feature on the key fob even in a situation where an ‘impatient passenger’ had prematurely lifted the door handle of the vehicle. In some prior art latches, such an action by an ‘impatient passenger’ would prevent the drive motor on the latch from unlocking the latch, thereby necessitating the owner to press the unlock button on the key fob a second time. There is some overlap in the components that used for the ‘impatient passenger’ feature and the components used for the emergency lock actuator, thereby reducing cost and complexity of the latch.

    Abstract: 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.

  • Patent number: 8186191
    Abstract: A locking paddle handle assembly for closures has a housing with a paddle handle pivotally mounted therein, a latch which latches and unlatches the closure upon rotation of the paddle handle, and a exterior key lock with a movable member that shifts between locked and unlocked positions. A deadbolt lock selectively engages the closure frame in the locked position to positively retain the closure closed. The deadbolt lock is operably connected with the movable key lock member, such that movement of the latter between the latched and unlatched positions contemporaneously shifts the deadbolt lock between the locked and unlocked positions. A remotely operable controller is operably connected with the deadbolt lock to power shift the same between the locked and unlocked positions from a remote location.

  • Patent number: 8141399
    Abstract: An electromechanical locking mechanism provides a plug with a rekeyable primary lock mechanism such as a tumbler stack, an electromechanical operator such as a solenoid or a motor, and an electronic circuit having a memory, or an electronic memory and an electronic logic stage, controlling activitiation and operation of the electromechanical operator, contained entirely within the plug. Insertion of a blade of a key that is properly profiled and bitted to correctly displace the primary lock assembly relative to a cylinder encasing the plug, and application by the key of electrical power, or of electrical power and a correct data signal, to the electronic circuit, will cause activation of the electrical operator and repositioning of a distal member of the operator relative to the cylinder, and thereby enable torque manually applied to the blade of the key to rotate the plug within the cylinder.

  • Patent number: 8085125
    Abstract: A system and apparatus are disclosed for indicating interactions between a key and a lock, and presenting this interaction information to the user. These apparatus and system are not specific to certain types of key or lock. In embodiments, the apparatus includes a number of detector switches to identify that the key has entered the lock. In other embodiments, the usage time is measured and presented to the user. In certain embodiments, the action performed with the key, ‘lock’ or ‘unlock’, is identified by a number of tilt switches or accelerometers to detect the direction of key rotation in the lock. An electric scheme and mechanical design of some apparatus embodiments are disclosed. A method for reading information by the user on the time of usage for a particular apparatus embodiment is described. A method for processing the interaction information in the form of records is also provided.

  • Patent number: 8079240
    Abstract: The invention provides an electronic door lock for a door having a first side and a second side. The electronic door lock includes a locking mechanism, a credential reader, and a programmable control circuit. The locking mechanism is coupled to the door and is movable between a locked position in which the door is inhibited from opening and an unlocked position in which the door is free to open. The credential reader is coupled to the door and is operable to read a credential. The programmable control circuit is coupled to the door and is operable to move the locking mechanism between the locked position and the unlocked position at least partially in response to the read credential. The programmable control circuit is selectively programmed to move the locking mechanism to a pre-selected either one of the locked position and the unlocked position in response to a failure signal.

  • Patent number: 8074479
    Abstract: An electromechanical locking system (8) comprises a lock (12) and a key (14). The lock includes a cylinder (16), an electronic control unit (18) which is housed within the cylinder, a tailpiece (20), and an electrically-operable clutch mechanism (22) which is housed within the cylinder (16). The cylinder (16) is rotatably mounted to a first component to be locked and the tailpiece includes an adapter (24) which is operable to interfere with the movement of a second component to be locked to the first component. The control unit (18) draws power from the key and is operable to generate an actuation signal for actuating the clutch mechanism (22) which releasably connects the cylinder and the tailpiece when actuated, thereby causing them to become rotatably coupled.

  • Patent number: 7987687
    Abstract: 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.
