This cylinder lock is a cylinder lock which can lock and unlock a mortise lock via a displacement transmission member. The cylinder lock comprises: a cylinder lock body; a key insertion part which is provided on one end side of the cylinder lock body and into which a key is inserted; and a displacement transmission member mounting part which is provided on the other end side of the cylinder lock body and on which the displacement transmission member can be mounted. A plurality of displacement transmission members corresponding to each of case locks having a plurality of specifications can be removably mounted on the displacement transmission member mounting part. Thus, cylinder locks having the same specification can be applied to case locks having a variety of specifications.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.

Provided is a mortise device. According to one embodiment, the mortise device includes a mortise installed at a door, a face plate coupled to one side surface of the mortise, a latch bolt which thrusts out of or retracts into the one side surface of the mortise to which the face plate is coupled, a guide protrusion formed on the latch bolt, and a fixing pin which allows the latch bolt to be installed in the mortise.

The present invention describes a means for unlocking and/or locking a privacy lockset via a magnet that is affected by a ferrous metal object or another magnet and, a means whereby said magnet travels in a controlled motion when affected by a ferrous metal object or said other magnet. As well as a trigger to secure or release a lock and a means whereby the motion of said magnet moves said trigger, whereby a magnet or ferrous metal object can be used to unlock or lock a privacy lockset. Rotational, lateral, and/or thrust forces are configured to move the trigger. The present invention may apply to rim locks, mortise locks, sliding door locks, cam locks, cylinder locks, and non-keyed deadbolts. Various materials or door styles may be provided.

A lock device with an electric locking function includes a latch head slideably mounted in a case and an unlatching mechanism mounted in the case. The unlatching mechanism includes a follower portion operatively connected to the latch head. The unlatching mechanism further includes a locking mechanism having an electric driving device for driving a locking block to move between a front position in which the unlatching mechanism is locked and a rear position in which the unlatching mechanism is not locked. Wire or wireless control can be provided to control a driving shaft of the electric driving device to move in a forward direction or a reverse direction to lock or unlock the latch head.

A door latch mechanism including a latch housing, a bolt having a proximal end with a head and a distal end having a latch, a hub including a central bore for receiving a spindle, a lever actuated by rotation of the hub, the lever including a slot in a top portion of the lever receiving the head of the bolt such that the lever and the bolt move together in both rearward and forward directions.

Mortise lock with an operating mechanism with a pinion that is turnable around a geometric axis and a rack engaging therewith that is movable along a direction perpendicular to the aforementioned geometric axis, whereby the pinion is provided with a double toothing with two sets of teeth that are separated by a geometric dividing plane that extends perpendicularly to the axial direction of the pinion, wherein the teeth of each set of teeth of the pinion form an oblique toothing, whereby the faces of these teeth are oblique with respect to the axial direction and these faces include an angle to one another that is such that the width of the teeth of each of the two sets of teeth either decreases or increases in the direction of the dividing plane.
