Abstract: A handle assembly is provided for use on storage compartment doors of a vehicle. The assembly includes inner and outer housings residing on opposite sides of the door. The handle assembly plunger resides on the inside of the door, rather than between the outside and inside door skins. An exterior handle can be grasped from either side for moving the plunger from an extended latched position to a retracted unlatched position for opening the door. An interior egress handle is provided to open the door from inside the compartment, as a safety feature. A key cylinder on the outer housing allows the handle assembly to be locked to preclude accidental or unauthorized opening of the door. The handle assembly allows the door to be opened by electric remote power and to be closed by slam action.

Abstract: A locking system for a stop button employed in a mortise lock having a spindle for operating a latch utilizing a first spindle base and a second spindle base which are nested relative to one another. Each base includes an opening for the mortise lock spindle such that the spindle may enter the combined first and second bases from the left side or the right side. A locking hub overrides either the first or second base and is capable of selectively lying over either the first or second base. An abutment linked to the stop button interacts with the locking hub such that either the first or second base may not be turned by the spindle when this occurs. Locking hub selectively locks either the first or second base through its position relative to the same and allows the mortise lock to easily transform from a left-hand version to a right-hand version.

The live bolt lock plate has a slot defined therein and is engaged with the first gear of the drive mechanism. The primary lock plate is engaged with the second gear of the drive mechanism and has a guide pin mounted thereon. The guide pin is positioned within the slot to slidingly couple the live bolt lock plate and the primary lock plate, in addition to their connection with the drive mechanism. A tumbler stack is associated with the primary lock plate for selectively allowing the primary locking plate to be moved to the unlocked position.

Abstract: The invention relates to a safe mechanism for resistance to drilling, by use of a door mounted crankshaft mechanism. The crankshaft includes a shoulder which transfers force to the safe door rather than transmitting it to other lock mechanism components. A crank plate attached to the crankshaft rotates from an open position to a locking position, and by rotation moves a link arm with attached locking pins laterally into engagement with the doorframe. A re-locker device locks both the crank plate and the link arm in place to make entry more difficult.

Abstract: A motor-vehicle latch assembly has a door latch displaceable between a locked and unlocked position, a housing forming a seat, a lever pivoted on the housing, and a linkage connected between the lever and the door latch for displacement of the latch between its positions by the lever. A lock cylinder can fit in the seat and with the lever and interengaging formations on the lever, housing, and cylinder retain the lever in a predetermined angular position on the housing except when the cylinder is fitted in the seat. The housing is centered on an axis and has an elastically deformable and axially rearwardly projecting tongue having a radially inwardly directed ramp surface. The lever projects radially from the housing and is formed with a radially outwardly open notch receiving the tongue in a predetermined angular position of the lever on the housing.

Abstract: A remote control locking device is provided for a door of a motor vehicle, which consists of a remote transmitter outside of the motor vehicle for transmitting a radio signal. A receiver is carried within and is electrically connected to the electrical system of the motor vehicle for receiving the radio signal from the remote transmitter. A piston is electrically connected to the receiver and is mounted within a door jamb of the motor vehicle adjacent the side of the door. A dead bolt plunger is axially aligned with and projects outwardly from the piston for a relative lineal movement between extended and retracted positions upon operation of the remote transmitter, so that the dead bolt plunger can engage with the side to lock the door and disengage from the side to unlock the door.

Abstract: An intermediate locking mechanism which is interposed between the existing door bolt works and the door knob of a standard key door lock, which can be unlocked by use of either a key or by entry of an electronic code, the mechanism includes the provision of an interconnecting means for interconnecting the door knob to the door bolt with which manipulation of the door knob withdraws the door bolt, a securing means for securing the interconnecting means to preclude its manipulation, an electrically operated means for unlocking the securing means by entry of an electronically entered combination code and a mechanical key operated means for unlocking the securing means by manipulation of a key. After entry of the combination code, the electrically operated means manipulates the securing means from a first normally locked position to a second position enabling unimpeded operation of the mechanism.

Abstract: A lock employing a lock cylinder protected by an outer escutcheon and positioned coaxially with a lock control mechanism and an inner doorknob. An outer doorknob is supported by the outer escutcheon and mounted on an axis which is offset with respect to the axis of the lock cylinder and inner doorknob. A cam and pushrod arrangement is utilized to transfer rotation of the outer knob to the lock mechanism. The encasing of the lock cylinder within the outer escutcheon instead of the outer knob increases the security of the device by making it more difficult to tamper with the lock cylinder. In addition, slight modifications prevent the application of excess torque to the outer knob from releasing the lock mechanism.

Abstract: In a door lock with spring bolt and dead bolt the lock follower body injection molded from thermoplastic synthetic resin is rotatably mounted in the lock case and resilient in itself without bias and without being influenced by any spring force when by radial movement of the lock follower body a plurality of legs extending therefrom bears against retaining pins and develops spring action by bending.The required spring load on the tumbler is effected by the provision of a free leg at the tumbler which rests unbiased against a stop pin and resiliently bends upon actuation by the key. The mounting of a door fitting at the door panel is facilitated by bores through sleeves provided in the lock case.The inexpensive fabrication permitting at the same time a maximum possible degree of dimensional precision is achieved by making both the lock case and the interior parts from thermoplastic synthetic resin containing no plasticizer. Preferably a polyacetal is used for the interior parts.

Abstract: PCT No. PCT/US 79/00088 Sec. 371 Date Feb. 15, 1979 Sec. 102(e) Date Feb. 15, 1979 PCT Filed Feb. 15, 1979 PCT Pub. No. WO80/01703 PCT Pub. Date Aug. 21, 1980A vehicle door latch assembly (16) is provided whereby a key (104) may be used to lock the door (10) and to prevent rotation of the outside door handle (20). A lock release lever (22) is provided inside the vehicle door for overriding the key lock (103) to permit the inside and outside handles (18,20) to operate to open the door. Even with the lock release lever (22) and the key lock (103) in the locked position, the inside handle (18) can be turned to move the lock release lever (22) to the unlocked position and to open the door. The outside handle (20) can now be used to open the door also. The outside handle (20) can also be released for operation by turning the key (104) in the lock (103) to the unlocked position.

Abstract: The electronic combination door lock uses a push button keyboard in combination with a door provided with a dead bolt manually operable by an outer turning knob. The electronic circuitry for the keyboard compares an input code with a stored code and generates an enabling signal only if the input code is the same as the stored code. The outer turning knob is restrained from being manually moved to retract the dead bolt when the door is in its locked condition. This restraining of the outer knob is removed by the enabling signal which requires very little energy so that the dead bolt can then be manually retracted. Since the major portion of the work involved in unlocking the door is a manual operation, very little electrical energy is required for the keyboard and circuitry and a battery can thus be used to thereby eliminate complicated wiring to exterior power sources.
