Abstract: A latch assembly comprises a first portion (32) defining an opening and a second portion (54) slidably disposed in the opening for movement of the first portion along the second portion. The second portion includes a stop which is larger than the opening for preventing further movement of the first portion along the second portion in a first direction. A securing element releasably connects the first portion and the second portion in a first relative axially connected position. In a mortise lock (20), the first portion and the second portion are thus movable together relative to the housing so that the first portion at least partially non-rotatably projects outwardly from the opening in the edge wall of the housing in an extended position and is inside the housing in a retracted position. Disconnecting the first portion from the second portion allows the first portion to move along the second portion in the first direction to a second axial position.

The driver is connected to the cover body, the actuator and the latch bar. Only one hand is required to unlatch the cover latch by rotating the actuator and the driver that moves the latch bar.

Abstract: A mortise lock having a double locking function is provided, which includes: a deadbolt for performing a locking function of a door by going in and out the door; a latchbolt going in and out the door by a handle installed on the door; and a locking member for maintaining the latchbolt in a locked state by keeping the latchbolt projected when the deadbolt is projected, whereby it is possible to improve the security, and reducing breakage and malfunction of the deadbolt due to forced operations of the door, since the door employing the mortise lock cannot be forcedly opened without breaking the latchbolt as well as the deadbolt.

Abstract: A lock including a frame, a handle operated latch bolt, a handle shaft, a latch bolt actuating mechanism and a mechanism for locking the handle shaft. The latch bolt locking mechanism includes a locking lever which is fixed with respect to the handle shaft and arranged to cooperate with a stop element on the frame. The latch bolt locking mechanism further includes an electromagnet which moves the locking lever with respect to the handle shaft or the stop element with respect to the frame so that the locking lever can be unlocked and locked behind the stop element. The locking device, which is either formed by the locking lever or by the stop element, is movable by the electromagnet in a direction forming an angle greater than about 45°, preferably greater than about 65°, with a flat plane extending at right angles to the longitudinal axis of the handle shaft. A more reliable locking and unlocking of the handle shaft can be produced.

Abstract: A convertible door latch assembly convertible between a non-locking configuration and a locking configuration. The convertible door latch assembly including a bolt housing, a bolt slidably engaging the bolt housing and having a first slot and a second slot, a drawbar slidably engaging the first slot and the bolt housing, a dead latch stop being engagable in the first slot to hold the drawbar in the first slot when the convertible door latch assembly is in the locking configuration, a plunger being slidably engagable in the second slot and being movable between an extended position and a retracted position when the convertible door latch assembly is in the locking configuration, and a pull slidably positionable within the first slot and moveable relative to the bolt when the convertible door latch is in the non-locking configuration.

Abstract: A lock mechanism for use with lever handles includes a lock core and a latch mechanism that is rigidly connected to the lock core to prevent the lock core from rotating in the door. Through-bolts are not needed, allowing a small diameter rose to be used. Stops and a spring return mechanism are entirely located within the lock core, allowing the rose to be thin. The lock core defines the rest position for the lever handles at an angle slightly above horizontal. To avoid the necessity for producing different locks in left and right-hand configurations, the lock core is made substantially symmetrical about a vertical plane, instead of a horizontal plane, and the inner and outer sides of the lock mechanism can be interchanged. A heavy-duty locking piece, including a pair of locking lugs that directly engage the lock core near its inner perimeter, allow the lock to withstand abusive forces applied through the lever handle.

Abstract: A door latching mechanism includes a slide housed within a frame adapted for sliding motion of the slide within the frame and a spindle rotatably mounted to the frame and adapted to move the slide between a retracted and an extended position. A void is defined between an exterior surface of the frame and an interior surface of a cover housing the frame and the slide. An insert includes wings, which extend into the void and are positioned on opposite sides of the slide from each other.

Abstract: A tubular lock. The lock can be directly actuated and unlocked by a key and includes an inner lock assembly mounted to an inner side of a door and an outer lock assembly mounted to an outer side of the door. The inner lock assembly includes an inner handle for turning a driving wheel of a latch assembly to retract a latch bolt. The outer lock assembly includes a lock and an actuating member operably connected between a drive member and a lock core of the lock. The driving wheel can be driven by an actuating tube of the drive member to retract the latch bolt.

Abstract: A lock chassis including a chassis housing having two substantially identical housing halves. The housing halves mate to form the housing when oriented 180° relative to each other. The housing halves include sidewalls having a lateral face positioned to abut the opposite housing half when the housing halves are coupled together. The housing is secured by lugs that mate with pockets in the lateral face of the sidewall of the opposite housing half and screws which extend through apertures in one housing half and into threaded holes in the lateral face of the sidewall of the opposite housing half.

Abstract: A mortise lock is provided including a housing for a latch bolt and a deadbolt which are mounted in the housing for movement between a retracted position where the latch bolt and deadbolt are inside the housing and an extended position where a portion of the latch bolt and deadbolt extend from the housing. A key-operated cylinder in the housing operates to move the deadbolt between the retracted and extended positions. A latch operator is also provided for retracting both the latch bolt and the deadbolt. A moveable blocking element in the housing prevents movement of the latch operator in one position of the blocking element. A locking lever operatively connects the deadbolt and the blocking element so that when the deadbolt is extended the blocking element is automatically moved to the position blocking the latch operator. The locking lever comprises an arm member integral with the locking lever.
