Closure Patents (Class 292/216)
  • Patent number: 8517433
    Abstract: The invention relates to a locking device for sliding doors, or for swinging-sliding doors of vehicles, particularly of rail vehicles, by which a locking pin connected to a door leaf is fixed in the closed position thereof. The device is characterized in that in the closed position of the locking pin the same is fixed in this position by a latch, a guide bar connected to the latch and having a notch assumes a position in which a locking element of a locking lever projects into the notch, thus fixing the position of the guide bar and the locking lever in turn is held in the closed position by a toggle lever mechanism that is located in the beyond dead point position.

  • Patent number: 8511723
    Abstract: A locking device includes a locking mechanism and a striker. The locking mechanism has a base plate, a hook, a pawl, a release lever, a thrust member, a locking spring and a thrust spring. The hook, when rotated, is capable of forming a locked condition in which the striker is held or an unlocked condition. The pawl is rotatably supported via a support shaft as a first shaft and is capable of rotating to a position in which the pawl can engage the hook. The release lever is rotatably supported via a support shaft as a second shaft. The release lever, when applied with a manipulation force for unlocking, is capable of rotating the pawl from the engageable position in a non-engaging direction. The thrust member is rotatably supported via the support shaft and is capable of further pressing the hook in the locked condition toward a locking direction. Further, the support shaft is positioned beyond the support shaft as viewed from an input point of the manipulation force to the release lever.

  • Patent number: 8505987
    Abstract: A latch assembly includes a latch movable between released and restrained positions and a latch spring biasing toward the released position. A first lever is movable between open and closed positions, corresponding to the released and restrained positions, respectively. A first lever spring biases toward the closed position. A second lever is movable between unlocked and locked positions, corresponding to the first lever open and closed positions, respectively. A second lever spring biases toward the locked position. An active material based actuator selectively moves the second lever from the locked to unlocked position in response to an activation signal. A primary activation mechanism selectively produces the activation signal without a mechanical connection to the passenger compartment. An auxiliary activation mechanism does not rely on the vehicle power system. A key or portable energy storage device may cause the activation signal from the primary or auxiliary activation mechanism.

  • Patent number: 8474883
    Abstract: A latching system for and a method of latching a first member to a second member are provided. The latching system includes a latching mechanism including a displaceable feature which, when operatively displaced, allows a striker to engage with a housing of the latching mechanism, at a recess defined by the housing, to provide supplementary or auxiliary latching force. The displaceable feature may be displaced by an actuating load transmitted between the striker and the latching mechanism, where the actuating load is substantially greater than the nominal load experienced by the latching system during ordinary latching conditions. The engagement of the striker with the housing at the recess may transfer a portion of the actuating load to the housing during the event generating the actuating load, thereby increasing the latching strength of the latching system and reducing the potential for deformation or distortion of the latching element during the event.

  • Patent number: 8347667
    Abstract: A locking paddle handle assembly for closures has a housing with a paddle handle pivotally mounted therein, a latch which latches and unlatches the closure upon rotation of the paddle handle, and a exterior key lock with a movable member that shifts between locked and unlocked positions. A latch lock selectively engages the latch, such that when the movable key lock member is in the locked position, the latch is retained in the latched position, wherein the closure cannot be opened. A deadbolt lock selectively engages the closure frame in the locked position to positively retain the closure closed. Both the latch lock and the deadbolt lock are operably connected with the movable key lock member, such that movement of the latter between the latched and unlatched positions contemporaneously shifts both the latch lock and the deadbolt lock between the locked and unlocked positions.

  • Patent number: 8336929
    Abstract: A double latch assembly for a motor vehicle having two pivotably mounted closure members is disclosed in which a sequencing lever is used to release first and second pawls used to hold first and second rotatable claws in respective latched positions. A single actuator A1 is used to release both of the pawls but because of the use of a disengageable coupling between the sequencing lever and the second pawl it is ensured that the first pawl is always released before the second pawl. Only a single actuator A1 is required to release both pawls and no sensors are required to control the sequencing of the pawls.

    Abstract: Provided is an automotive door latch device, including: a latch pushed to rotate by a striker; a latch return spring for biasing the latch toward a return position thereof; a pawl engageable with the latch to inhibit the latch to pivot in a door opening direction (return position); and a pawl return spring for biasing the pawl toward a return position thereof. A housing part of a body, which houses the latch and the pawl, is opened downward at a position below the pawl on one side of the body. The pawl return spring is assembled to a spring mounting part formed on another side of the body at a position spaced downward from a rotational support part of the pawl, and includes a pawl-side end part that engages with the pawl through a through hole provided in the body. Thus, dust or the like entering the housing part of the body, which houses the latch and the pawl, can be discharged out of the body with higher efficiency.
