  • Patent number: 7145436
    Abstract: A door opening and closing apparatus has a motor, a door latch and a power generation mechanism. When the voltage of the battery is below a level needed to drive the electric actuator, a predetermined manipulation of the power generation mechanism generates the power needed to drive the motor. Therefore, when the voltage of a battery that supplies electric power to the electric actuator is below a level needed to drive the electric actuator, the door opens.

  • Patent number: 6919797
    Abstract: A remote-controlled lock includes a bottom base, a transmission motor, a connecting rod, a sleeve, a deadbolt, a spring and a casing. The transmission motor is started to rotate clockwise together with the stop member on its shaft by pressing the unlocking button of a remote controller, letting the stop member disengaged from the stopper of the sleeve. Thus, the sleeve and the deadbolt can be moved inward to unlock the remote-controlled lock. On the contrary, pressing the locking button of the remote controller starts the transmission motor to rotate counterclockwise together with the stop member to let the stop member block the stopper of the sleeve. Thus, the sleeve is restricted in position, unable to be moved inward, and the engage member of the deadbolt is engaged in the engage groove of the engage base of a doorjamb to lock the remote-controlled lock.

  • Patent number: 6845641
    Abstract: A remote-controlled door lock includes a housing provided inside with a lock base, a deadbolt, a battery base, a circuit board and an actuating device. The deadbolt is fixed with a stopper on the center portion. The locking button of a remote controller is pressed to send out a locking signal to the circuit board to start the motor of the actuating device to rotate. Synchronously, the rotating shaft of the motor actuates a rotary member to rotate together with its notch, which rotates to reach the stopper of the deadbolt and holds the stopper immovable therein, rendering the deadbolt unable to be moved inward. Thus even if the lock rods of the lock base are pried unlocked, the door lock is still impossible to be unlocked before the actuating device is driven by a remote controller to release the deadbolt, having best effect of anti-theft.

  • Patent number: 6619085
    Abstract: A remote-controlled lock includes a shell, an engage base, a fix base, a motor, a circuit board, an actuating member, a passive member and a spring. The circuit board receives a locking signal from a remote controller and starts the motor to rotate clockwise together with the actuating member, which pushes the passive member to move outward and has its projections engaged with the projections of the passive member, which compresses the spring to force its deadbolt extend outward and inserted in the insert groove of the engage base to finish locking of the lock. The circuit board receives an unlocking signal and starts the motor to rotate reversely together with the actuating member, letting the passive member moved inward by the recovering resilience of the spring and the deadbolt disengaged from the insert groove of the engage base to finish unlocking of the lock.

  • Patent number: 6615624
    Abstract: An anti-theft system for motor vehicles. The preferred embodiment is designed to prevent theft by preventing a vehicle's wheels from turning when the system is activated. In the preferred embodiment, there are inhibitors in the disc rotors of each wheel. Next to each wheel, there is a solenoid, within which is a locking pin or piston rod. When the user enters an activation coded key in an ignition, the solenoids are energized, causing the piston rods to move outward into arcuate recesses, thus preventing the rotor discs from turning. A deactivation code must be entered in the ignition to de-energize the solenoids, causing the piston rods to move back into the solenoids and releasing the rotor discs. Optionally, the parking brake may also be locked when the system is activated.

  • Patent number: 6609400
    Abstract: There is a lock release apparatus for providing delayed passage past a movable barrier such as an exit door which is held to a closed position by a lock. The apparatus includes a beam transmitter, a beam receiver, a timer for releasing the lock after a predetermined delay, a trigger associated with the timer and a beam reflector affixed to an operating bar on the movable barrier. In use of the apparatus when the barrier is closed and locked the transmitter directs a beam onto the reflector at an orientation such that reflection is detected by the beam receiver when the operating bar is undisturbed. Subsequent movement of the operating bar to open the barrier terminates or shifts the reflection away from the receiver to trigger the timer to release the lock after the predetermined delay.
