A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A latch assembly is provided where the latch is moveable to open and close a door by operation of a dead lock assembly that blocks or unblocks movement of a bolt. In a blocked state, a blocking cartridge of the dead lock assembly is prevented from inward movement, blocking inward movement of the bolt. Turning a door knob or door handle causes a spindle extending through the dead lock assembly to move locking bars of the dead locking assembly, the locking bars moving further apart to permit the blocking cartridge to slide there between and move inwardly into the latch housing. The bolt can now move inward by force of the door jamb upon the bolt in order to clear the door jamb when opening and closing the door.

A combination lock is provided, the lock having a latch movably mounted to a housing of the lock for movement between a locked position and an unlocked position; and a bolt movably mounted to the housing of the lock for movement between a first position and a second position, wherein the combination lock is a key-controlled combination changing permutation lock wherein a button disposed away from a rear exterior surface of the housing in a first direction rearwardly away from the rear exterior surface is depressed in order to change the combination of the combination lock and the housing has a button protection feature extending rearwardly away from the rear exterior surface of the housing in the first direction proximate to the button and the button protection feature extends farther away from the rear exterior surface of the housing in the first direction than the button.

A tamper-resistant sash window lock includes a housing, a shaft, a cam, and a lever member. An interior surface of the housing wall that defines a cavity. A portion of the interior surface of the housing wall is curved about a hole in the housing, with a distal end of the wall portion formed into a lock surface. The shaft is rotatably mounted in the hole, and a hub of the cam is rotatably mounted on the shaft. The cam has a cantilevered arm with a lock surface and an engagement surface. The lever member is fixedly secured to the shaft, for a first side thereof to engage and drive the cam hub in a first rotational direction into a lock position when the shaft is actuated in the first rotational direction, so the lock surface of the cantilevered arm engages the lock surface of the housing preventing forced entry.

The present invention relates to a locking device 1 having a deadbolt 104 within a casing 102, which deadbolt 104 is movable between an advanced position wherein it protrudes from a front face of the casing 102 and a retreated position, wherein it is retracted into the casing 102. The locking device 1 comprises: a link plate 130 which moves the deadbolt 104 to the advanced position; a deadbolt blocking member 110 which is moveable between a blocking position blocking the deadbolt 104 in the advanced position and an unblocking position to allow the deadbolt 104 to move to the retreated position; an electrically driven actuator unit 120 which moves the deadbolt blocking member 110 between the blocking position and the unblocking position; and a control circuit configured to control the electrically driven actuator unit 120 so that once the deadbolt 104 is moved to the advanced position, the deadbolt blocking member 110 is moved to the blocking position by actuation of the electrically driven actuator unit 120.

A multipoint lock assembly for a swinging door panel includes a mortise housing that is installed in a mortise along the non-hinged edge of the door panel. A latch operating mechanism and a lock operating mechanism are disposed in the mortise housing. Each of these mechanisms is designed to be operated with a standard rotary operator such as a handle or knob for the latch operating mechanism and a key and/or thumb turn for the lock operating mechanism. The latch operating mechanism is transitionable between left- and right-hand orientations and includes a deadlatch feature that prevents forced back-drive. Turning the key and or thumb turn of the lock operating mechanism extends a deadbolt and extends upper and lower shoot bolts from edges of the door. When extended, the shoot bolts also are secured against forced back-drive by unique mechanism configurations.

A multipoint door lock system comprises a door frame having a bolt opening and a secondary opening. A latch takes an activable position when the door is opened and a pre-armed position when the door is closed. A door-locking tip of the latch protrudes from the secondary opening of the door frame and into a secondary bore of the door when the door is closed. A transfer block moves from an inactive position to an active position upon insertion the deadbolt in the bolt opening. A biasing element causes a displacement of a translating member when the transfer block moves to the active position in the absence of a force sufficient to cause a compression of the biasing element. This action of the translating member locks the latch in its pre-armed position within the secondary bore.

A latch includes a housing that has a first side and a second side. The latch includes a bolt locking assembly that is positioned at least partially within the housing. The bolt locking assembly includes a bolt movable between first and second positions relative to at least one of the first and second sides of the housing. The bolt is positionable to selectively extend from either the first side or the second of the housing. The latch includes a first handing configuration and a second handing configuration, where the first handing configuration corresponds to the first position and the second handing configuration corresponds to the second position. Changing between the first handing configuration and the second handing configuration requires moving the bolt locking assembly to a disengaged position and applying the external force to the bolt to move the bolt between the first and second positions.

The present disclosure is drawn to a sliding panel latch system and related methods. The sliding panel latch system can comprise a striker, a sliding panel movable relative to the striker, and a latch rotatably coupled to the panel. The latch can have a striker interface to engage the striker. The striker interface can at least partially define a striker opening to receive the striker. The latch can be rotatable to a latch position to secure the striker in the striker opening and to a receive/release position to receive the striker in the striker opening or release the striker from the striker opening.
