Sliding Door Patents (Class 70/95)
  • Patent number: 11401735
    Abstract: A sliding door latch system and method is disclosed herein. The sliding door latch system is used to prevent movement of a sliding door between a closed position and an open position relative to a fixed door frame. The device may be installed as a secondary safety latch on a sliding door having a primary latch that is located at an elevation within the reach of the child. The device may be installed at an elevation above the reach of the child, but readily within the reach of an adult user. The sliding door latch includes a latch arm located outside the sliding door to simplify installation. The latch arm is user-locatable in a latched position, a momentarily released position, and a held-in-release position.

  • Patent number: 8973416
    Abstract: A lock includes a bolt having latching and unlatching positions, and a locking component having a locking position in which the bolt is prevented from moving from the latching position to the unlatching position, and an unlocking position in which the locking component does not prevent the bolt from moving. A lock cylinder includes a cam having unlocking and deadlocking positions. A deadlocking component has a disengaging position in which the deadlocking component does not prevent the locking component from moving from its locking position to its unlocking position; and when the locking component is in its locking position, an engaging position in which the deadlocking component prevents the locking component from moving. When the cam is in its unlocking position, the locking component is in its unlocking position and a deadlocking component is in its disengaging position, and conversely when the cylinder cam is in its deadlocking position.

  • Patent number: 8938998
    Abstract: The lock has a rotatable latch. The latch is mounted for movement between a position wherein it engages a fixed part of the vehicle to secure the door in the closed position and a position remote from the fixed part of the vehicle such that the door can be opened. A latch movement preventing member is moveable relative to the latch between a position remote from the path of movement of the latch, wherein the latch is free to disengage the fixed part of the truck, and a position intersecting the path of the latch, wherein movement of the latch to disengage the fixed part of the truck is blocked. A pair of magnets are oriented to force the member to move from its remote position, against the action of a spring, to its intersecting position, to prevent the latch from disengaging the fixed part of the truck.

  • Patent number: 7874745
    Abstract: A lock mechanism for a sliding object includes a slide arm, a rotating lever, and urging means. When an external pressing force presses the slide arm member in opposition to an urging force imparted by the urging means, the slide arm member is moved along a slide path, thereby causing the rotating lever member to rotate. When the slide arm member is pressed further, the tip of the rotating lever member rides onto and is stopped against the lateral surface of the slide arm member, such that the slide arm member and the rotating lever member remain stopped at the current position even if the pressing force is released.

    Abstract: Systems and methods are described for controlling a breakaway feature in a sliding door. The sliding door can be mounted in a doorway on a door hanger. The door is typically attached at one end using a hinge mechanism and maintained in planar alignment with the doorframe by a controllable mechanism such as an electromagnetic shear lock. An activation switch, such as a push-bar switch, initiates a delayed egress sequence that disengages the shear lock by controlling an energizing current in a magnet. When the shear lock is disengaged, the door can swing on the hinged mechanism. The delayed egress sequence can include one or more delays prior to disengaging the shear lock. Override signals can inhibit or force disengagement of the shear lock.

  • Patent number: 7066500
    Abstract: A lock is provided for a vehicle having a door and a fixed part proximate the door. The lock includes a housing attached to the vehicle door. Latch means, including a hook, are mounted for rotation relative to the housing about an axis. The latch means rotates between a first position, wherein the hook engages a part of the vehicle to secure the door in the closed position, and a second position, wherein the hook is remote from the vehicle part such that the door can be opened. A latch rotation preventing member is moveable, relative to the housing, in a direction substantially parallel to the axis of rotation of the latch, between a forward position, remote from the path of movement of the latch means and a rear position, intersecting the path of the latch means to retain the latch means in its first position. Means are also provided for biasing the member toward the rear position.

  • Patent number: 7040671
    Abstract: A lock assembly includes a casing, two pivotable members pivotally mounted in the casing and meshed with each other, two linking rods, and two hook device each including a hook member and a rocker arm that is pivotally mounted in the casing. Each hook member has a first end pivotally connected to an associated rocker arm and a hooked second end that is passable through an associated one of two openings of the casing. When either pivotable member is pivoted, each rocker arm and each hook member are actuated such that the hooked second end of each hook member is moved between a retracted position in the casing and a locking position out of the casing. Damage to the hooked second ends of the hook members during closing of a door is prevented.

  • Patent number: 6349576
    Abstract: A lockable sash assembly for installation on a window assembly is provided. The window assembly includes sashes movable relative to each other to open and close the window assembly when the lockable sash assembly is in a window-openable condition and substantially unmovable relative to each other when the lockable sash assembly is in a window-unopenable condition. The sash assembly includes a sashlock having a rotating device (such as a lever-controlled cam) which is movable between a window-openable position and a window-unopenable position. The sash assembly also includes a locking device which is convertible between a locked state whereat the rotating device is blocked from moving from the window-unopenable position to the window-openable position and an unlocked state whereat the rotating device is unblocked from moving from the window-unopenable position to the window-openable position.

  • Patent number: 6247341
    Abstract: In a lock for sliding door, window or like closure the slider has on its face adjacent the outside wall of the casing a member projecting a predetermined distance which projects through the slot in the locked position of the slider and abuts against the edge surface of the outside wall defining the longitudinal end of the slot. A return spring between the slider and the casing spring-loads the slider towards the outside wall of the casing but allows movement of the slider in the direction perpendicular to the outside wall over a distance at least equal to the predetermined distance.

  • Patent number: 6196034
    Abstract: A latch assembly incorporates a pair of overlapping tubular guard projections respectively secured to a pair of opposing structural members, at least one of which is disposed on a slidable partition. As the projections are tubular, the projections isolate the enclosed area within the projections from all sides. Moreover, as one projection overlaps the other, no gaps are present that could otherwise permit access to the enclosed area within the projections. As such, whenever a latch member projects through the enclosed area within the overlapping projections, the latch member is substantially protected from unauthorized tampering.
