摘要:
A dead bolt lock automatically blocks the extended bolt to prevent externally-applied force from thrusting the bolt back into the lock case, and in the event of physical attack the lock responds by prolonging or perpetuating the dead bolt blocking condition. A push-pull lock has a bolt whose motion in both directions is stopped in response to detection of a rise in motor current above a certain level: a cushioning arrangement allows the current-limiting feature to be implemented without risk of damage to the motor, gear teeth or other drive components. A re-locker arrangement includes an angled flange that is part of a motor-supporting bracket; when forcibly pressed, the flange breaks plastic pins to release a spring-biased re-locker wire to block the bolt from being withdrawn, and when the wire is in the dead bolting position an extension of the re-locker wire engages a ridge in the lock's case to prevent the re-locker from being manipulated back to its original position. Either lock can control the position of a bolt works blocking element that selectively engages a lever-driven mechanism that blocks and unblocks the door from being opened. A sensor switch, especially for use on the push-pull lock, tells the lock when the mechanism is in a secured position, so that the lock is automatically re-locked and the user does not have to manually extend the bolt. Finally, the system has a keypad tampering detection and response system, remote enable/disable unit, duress detection and response unit, low-battery sensing arrangement, bolt extension indication feature, adjustable bolt throw feature, and audit trail feature.

A keyless locking system includes a housing in a generally rectilinear configuration having a plate with peripheral edge walls to form an open housing there between. A rotatable assembly is secured to the front wall and includes a visible rotator extending inwardly from the front wall and a cylindrical shaft extending through the front wall. A C-shaped channel member extending interiorly from the front wall to encompass and contact the sides of the deadbolt. A gearing assembly includes a large gear coupled to the channel member and a smaller gear and an intermediate gear whereby rotation of the intermediate gear will rotate the smaller gear and then the larger gear to rotate the channel member and deadbolt to lock and unlock the door. A motor within the housing with an associated battery drives the intermediate gear. An electronic assembly effects the driving of the motor and intermediate gear in a first direction and then a second direction. A control member, adapted to be held by the hand of the user, includes an actuator adapted to be moved to drive the motor a predetermined number of revolutions to rotate the intermediate gear, small gear, large gear, channel member and deadbolt for either locking or unlocking the door. An adhesive is secured to the housing interiorly of the edge walls to secure the housing onto a door with the channel member over the deadbolt of the door.

A motor vehicle door lock system including a vehicle lock adapted to be locked and unlocked, a lock element adapted to be moved between a locked position and an unlocked position for locking and unlocking respectively the vehicle lock, a central interlock drive having a slow running drive element for moving the lock element, a remote control module, control electronics with a passive entry function to at least passively unlock the vehicle lock, and a high-speed electromagnetic drive for rapidly moving the lock element from the locked position to the unlocked position to thereby unlock the vehicle lock quicker than by operating the drive element. The passive unlocking of the vehicle lock occurs over time requiring a reaction phase with a starting interval, an authorization check interval, and an action interval, the starting interval being initiated by an operator. The high-speed electromagnetic drive is immediately activated at start of the action interval, and subsequent to the activation, the central interlock drive is operated to move the slow running drive element to a position corresponding to the unlocked position of the lock element.

An electrically operated, strong, security system comprising a lock with remote control installed in a wall adjacent to a door frame or under a door. The lock comprises at least one rod which extends into the door when the door is closed and in a locked state. In an unlocked state an actuator retracts the rods from the door, back into the door frame or into the floor. The security lock system provides a manual control for the lock inside a house or building along with indicator lights showing the lock status. An emergency DC battery provides power for the security lock if there is a primary power outage. A remote control locks all doors in the house simultaneous that have such a security lock, and the remote control unlocks only the door or doors selected to be unlocked. The underfloor embodiment of the lock comprises mounting an elongated moveable rod within the door whereby the rod extending from the underfloor lock pushes the door rod upward into the top of the door frame thereby securing the door at the top and the bottom.

A keyless locking system comprises a housing with a planar plate constituting a front wall and peripheral walls extending inwardly to form an open housing. A rotatable assembly is rotatably secured within the housing. The rotatable assembly includes a rotator with a cylindrical shaft, a spring loaded retention member, a channel member and a trapezoidal end plate. The channel member has a parallel plate with a pair of sidewalls to encompass and contact the sides of a deadbolt. The first end has a retention bar between the sidewalls. A gearing assembly and an associated motor are provided. An electronic assembly is provided to effect the driving of the motor and worm gear. An associated switch initiates the driving of the electronic assembly and motor. Provided last is a control member. The member is adapted to be pressed to drive the motor rotating the gear assembly and channel member and deadbolt.

An electronic chip functioned lock whose tongue piece revolving mechanism is either manually operatable with a mechanical key, or by an electronic chip attached key. The lock mechanism is connected to a computer for reading input information to confirm the code stored in the chip so as to avoid unauthorized entry, and to amend, store, or erase the data in case of need. The computer can further be interconnected to a local security system.
