The door handle is of the type which is incapable unlatching the door when the locking mechanism locks the latch. The door panel has an opening for receiving the manual lock actuator when moved to its locked position so that the manual lock actuator is substantially recessed within the door panel. The manual lock actuator and the door panel are constructed such that the manual lock actuator cannot be accessed through the opening for manual movement back to its unlocked position. The power lock mechanism can be actuated to unlock the door, but only from a location which is remote from the door itself.

  • Patent number: 5669642
    Abstract: The present invention provides an outside door handle automatic locking device for automobiles which includes supports that are placed on both sides of the upper portion of a housing, levers, placed on both sides of a handle and inwards from the supports, which, because of being fixed to a hinge shaft, are able to rotate. Also, an elastic member is formed on the hinge shaft that keeps the outside handle in its original position through its elasticity. Additionally, placed on a fixed location on one of the levers is a rotating member that rotates when the vehicle receives a side impact from a collision. A hook portion is also offered which is fixed toward the outside of the rotating member and catches the rotating member when it rotates past its fixed rotation.

  • Patent number: 5626372
    Abstract: A mechanically operated latch includes a stop member and a restraining member which are disposable between an engageable position and a disengageable position. In which a restraining member (14) is displaceable between a first position in which an abutment surface is engageable with the stop member (18) which is attached to the cabinet frame to permit only limited opening movement of the panel and a second position in which the abutment surface is not engageable with the stop member to permit unlimited opening movement of the panel. The force required to activate the latch is such that it can be overcome by an adult but not by a small child.

  • Patent number: 5605362
    Abstract: This exit device has a press bar and an elongated deadbolt adapted to be mounted horizontally adjacent the free end of the door and a pivoted retractor blade inward of the door. The blade is pivoted by the press bar and engages with its nose a projecting surface on the deadbolt and retracts the deadbolt. The blade also has a keeper contact surface which, as the door closes, is contacted by the keeper and the blade is pivoted inward to retract the deadbolt. The retractor blade also serves as an anti-friction bearing having a peripheral portion which rolls against the deadbolt and counters against the inward force on the deadbolt opposing to the opening force on the door.

  • Patent number: 5597188
    Abstract: A latching device which detects the initial shocks of major earthquakes and activates safety devices before the onset of destructive ground motions. A unidirectional vertical threshold seismoscope is integrated with mechanical and electromechanical safety devices to latch cabinets closed, secure movable objects, shut off gas, water, and electric utilities, activate alarms, early warning networks, and related automated response systems. The device is fully self contained, requires no external power, and is virtually impervious to nonearthquake noise in that it is designed to respond specifically to the vertical acceleration and displacement characteristic of the initial shock waves of a major earthquake.

  • Patent number: 5584517
    Abstract: An improved secure latch for a fixture having a door with a double-wall structure, including an endwall with an exit port and an inner sidewall with a slot near the endwall and parallel thereto. An entry port of a facing member and an orifice of a tongue, slidably receivable through the slot, of a latch attached to the facing member are aligned with the exit port as the door is in a closed configuration such that a bolt of a lock installed in the door is slidable therethrough as the bolt is displaced between a locked configuration and an unlocked configuration. The secure latch is adapted to retain the door in a closed configuration as the bolt is in a locked configuration even though the facing member may be forced clear of the bolt. Further, the secure latch prevents the lock from being sprung open without inflicting severe and visible damage to the door and/or the facing member. A modified embodiment provides the endwall without the exit port and the facing member without the entry port.

  • Patent number: 5570914
    Abstract: The Earthquake Actuated Door Latch mounts outside a cabinet or beside the cabinet door. The device contains a pivoted catch assembly with a weight on one end and a door catch, or hook, on the other. The catch assembly is stable in two positions, one on each side of the cabinet door. An earth tremor causes the weight to shift out of the cocked position to the operated position (the second stable position) putting the hook where it interferes with opening of the cabinet door. Weight and hook move as a unit, minimizing delay, and an internal lock prevents rebound.
