  • Patent number: 5277461
    Abstract: A vehicle door latch has a fork bolt lever that is latched by a detent lever. The detent lever is operated by an intermittent lever that is operated by a transfer lever that is actuated by inside and outside door handles via operating levers. The door latch includes with a locking lever that disconnects the door handles from the intermittent lever when it is in the locked position. The door latch also includes an interlock between the intermittent lever and the locking lever that is automatically engaged in response to the position of the detent so that the door latch cannot be locked when the fork bolt lever is in an unlatched position. Consequently the door latch can only be locked when the door is closed and the fork bolt lever is in a latched position. This prevents the driver from locking his or her keys in the vehicle.

  • Patent number: 5273324
    Abstract: A power door lock device comprises a latch plate pivotal about a first axis to assume an open position, a half-latch position and a full-latch position; a sub-lever pivotal about a second axis which is in parallel with the first axis; and a close lever pivotal about the second axis. The sub-lever has an engaged edge and is pivotally connected through a link to the latch plate, so that when the sub-lever is pivotal about the second axis to assume first, second and third angular positions, the latch plate takes the open position, half-latch and full-latch positions respectively. The close lever has an engaging edge which, when the close lever is pivoted from an inoperative position to an operative position, is brought into abutment with the engaged edge of the sub-lever to pivot the sub-lever from the second position to the third position. An electric drive device is used for forcing the close lever to pivot between the inoperative and operative positions.

  • Patent number: 5273325
    Abstract: A motor-vehicle door latch has a bolt projecting from a support and movable by an actuator between an advanced and a retracted position, and a housing movable between an open, a partially closed, and a fully closed position. A latch fork can engage the door bolt to retain same and lock the door. The servoactuator can, when the bolt is engaged with the fork, move the housing between the partially and fully closed positions. A pawl pivots on the housing between a holding position retaining the fork in the latched position and a freeing position permitting the fork to move out of the latched position. A release lever on the housing displaces the pawl from the holding to the freeing position. A opening lever on the housing operatively engageable with the support is coupled to the pawl for moving it from its locked to its unlocked position on movement of the opening lever from a cocked to a rest position.

  • Patent number: 5271649
    Abstract: An over center draw latch with lock bolt action which performs the functions of both a bolt type latch and a draw type latch. The latch comprises a housing mounted on one panel, a lever rotatably mounted on the housing, a spring rotatably mounted on the lever and a keeper mounted on another panel. When the latch is fastened, the spring engages the keeper to thereby draw the panels together. In addition, a portion of the lever engages the keeper to provide a lock bolt action. In the closed position, the latch prevents relative movement of the panels in all directions.

  • Patent number: 5269573
    Abstract: A device for restricting the opening motion of a door comprises a housing (4) for securing to the door and having an opening (6) facing the floor over which the door moves when it is opened and closed. A pivotally movable cam member (5)(5') is mounted within the housing so that it can pivot between an operating position in which it extends through the opening to engage with the floor and prevent opening movement of the door and a retracted position in which it is spaced from the floor. Levers (18,21) (18',21') are provided for moving the cam member between its operating and retracted positions.

  • Patent number: 5267760
    Abstract: A locking mechanism comprises a plurality of spring loaded tines disposed around an armature. The armature has a disc mounted thereon the radially outer surface of which is profiled. The armature is coupled to a solenoid which is selectively energized to move the armature. In a locked position the profiled surface of the disc urges the spring loaded tines outwardly into engagement with a locking cup. In an unlocked position the armature moves the disc into a position so that the profiled surface allows the tines to spring inwardly so they can be withdrawn from the locking cup. A spring loaded sleeve is provided which holds the tines and the armature in the unlocked position so that the locking mechanism can re-engage in the event of a power failure to the solenoid. A pin is provided so that the solenoid can be overridden manually.

  • Patent number: 5261713
    Abstract: An electromagnetic door lock comprises in combination a convex armature plate and oblong magnet whereby the plate is flattened into full contact with the magnet when energized. De-energizing the magnet allows the plate to spring back to the convex shape and elastic means to instantly separate the armature from the magnet. One or more reed switches are located in cavities in the support bracket for the magnet. The reed switches are positioned to sense a substantial change in the leakage flux caused by an "air gap" between the armature and the magnet and thereby infer full locking or unlocking of the door lock.
