  • Patent number: 10890020
    Abstract: A double latch lockset, or its kit form, generally includes first and second retractable latches connected by a drive assembly. The first retractable latch may be activated by a first inside and/or outside actuator, and the second retractable latch may be activated by a second inside and/or outside actuator that activates the second retractable latch (such as a deadbolt) independently of the first retractable latch. Movement of the first inside and/or outside actuator in a first direction simultaneously retracts the first and second retractable latches, and movement of the first inside and/or outside actuator in a second direction locks the second retractable latch. The first inside and outside actuators may be configured to move in the second direction without retracting the first retractable latch.

  • Patent number: 8393187
    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 an exterior key lock with a movable member that shifts between locked and unlocked positions. A deadbolt lock selectively engages the closure frame in the locked position to positively retain the closure closed. The deadbolt lock is operably connected with the movable key lock member, such that movement of the latter between the latched and unlatched positions contemporaneously shifts the deadbolt lock between the locked and unlocked positions. A remotely operable controller may be mounted either horizontally or vertically relative the handle assembly and is operably connected to a multi-armed lock cam to power shift the deadbolt lock between the locked and unlocked positions from a remote location.

  • 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: 8347668
    Abstract: A differential linkage attachment of handles includes a first handle ring and a second handle ring placed on right and left sides, respectively, and set in a rectangular dead bolt shifting block independently. An end of the second handle ring is encircled with a first slanted latch bolt shifting plate, and an end of the first handle ring is encircled with a second slanted latch bolt shifting plate. All of the five parts turn around on a center axis. When the second handle ring turns forward or clockwise, the rectangular dead bolt shifting block or the first slanted latch bolt shifting plate is linked to turn around on the center axis independently, and when the first handle ring turns clockwise, the rectangular dead bolt shifting block or the second slanted latch bolt shifting plate is linked to turn around on the center axis independently.

  • Patent number: 8261584
    Abstract: The reversible mortise lock of the present invention can be installed on either the left or right side edges of a door opposite the door hinges. The lock includes a housing with a live bolt pivotally and slidably mounted in the housing. The live bolt slides between an extended position beyond the housing and a fully retracted position within the housing. When fully retracted, the live bolt can be rotated 180° so that the beveled face of the live bolt can be reversed. A finger pivotally mounted within the housing blocks full retraction of the live bolt when the mortise lock is installed in the door.

  • Patent number: 8234892
    Abstract: A mortice lock is disclosed which has a lock casing which provides a first point of entrapment and a second point of entrapment, a latch bolt which can move between a latching position and an unlatching position, a handle for moving the latch bolt between the latching position and the un-latching position, a key cylinder, an operating assembly and a locking member. The operating assembly can move between a first position in which a deflectable portion of the operating assembly engages with the first point of entrapment and a second position in which the deflectable portion engages with the second point of entrapment. Only the key cylinder can move the operating assembly between the first position and the second position.

  • Patent number: 8161780
    Abstract: A thumb operated door latch and lock assembly has an exterior grip and thumb lever, a motion converter, a key cylinder, a strengthening plate and an interior latch lever and locking knob. The thumb lever moves the converter which turns a latch tongue that extends through a receiver in the latch assembly. The interior lever turns a limited engagement interior hub collar. A figure eight opening in the collar turns the latch tongue to withdraw the latches. Turning the interior lever upward disables the thumb lever. Turning the lever to withdraw the latches moves a slide upward within guide plates. The slide turns an interior lever and an extended tongue on the key cylinder to withdraw the dead bolt simultaneously with the latches.

  • Patent number: 8146392
    Abstract: A latch has a housing and a dead bolt shiftable on the housing between extended and retracted positions. A latch nut is rotatable on the housing and connectable to door handles and carries actuating and panic levers. An actuating element is connected between the dead bolt and the actuating lever, and a panic element is connected between the panic lever and a locking pawl and is movable between an unactuated position and an actuated position to shift the locking pawl into an unlocked position. A key cylinder on the housing has a movable actuating lug movable between a locking end positing and a freeing end position. A pivotal locking pawl is shiftable by movement the actuating lug of the key cylinder into a locked position blocking movement of the actuating element and holding the dead bolt in the extended position and an unlocked position freeing the bolt and actuating element.

  • Publication number: 20110314878
    Abstract: A combination door latch and deadbolt assembly that has first and second configurations for use with a door having a deadbolt aperture and a latchbolt aperture spaced by either a first vertical distance or a second vertical distance. The second vertical distance is less than the first vertical distance. In the first configuration, an insert slide is connected to an interconnect slide for vertical movement with the interconnect slide and the interconnect slide is operably connected to a deadbolt assembly via the insert slide. The insert slide and interconnect slide are movable vertically to move a deadbolt from an extended position to a retracted position in response to movement of an interior actuator from a first position to a second position. In the second configuration, the interconnect slide is operably connected to the deadbolt assembly without the insert slide.
