An example lockset generally includes a housing, a bolt, a turnhub, and a spindle. The bolt is mounted in the housing for movement between an extended position and a retracted position. The turnhub is rotatably mounted in the housing and engaged with the bolt. Rotation of the turnhub in a bolt-extending direction drives the bolt toward the extended position, and rotation of the turnhub in a bolt-retracting direction opposite the bolt-extending direction drives the bolt toward the retracted position. The spindle engaged with the turnhub, is operable to exert torque on the turnhub in the bolt-retracting direction, and is selectively operable to exert torque on the turnhub in the bolt-extending direction. The housing includes a pair of stops configured to limit rotation of the spindle to a predetermined angular range.

A latch control device includes a connecting seat divided by two integrally formed walls into a hollow portion and a mounting portion spaced from the hollow portion. A detecting module is disposed between the two walls. A locking member is pivotably mounted between the two walls. A first restraining member is disposed in the mounting area and is configured to lock or unlock the locking member, controlling pivotal movement of the locking member. When the locking member is not pivotable, a latch of a door lock in the hollow portion is restrained in the hollow portion, preventing opening of a door to which the door lock is mounted. When the locking member is pivotable, the locking member can pivot while the door pivots, permitting opening of the door.

An exemplary apparatus includes a housing, a lock mechanism mounted to the housing, an electromechanical driver, a first override mechanism, and a second override mechanism. The electromechanical driver is mounted to the housing and is operable to unlock the lock mechanism. The first override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The second override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The apparatus has a first configuration in which a lock cylinder is engaged with the first override mechanism such that actuation of the lock cylinder unlocks the lock mechanism. The apparatus has a second configuration in which the lock cylinder is engaged with the second override mechanism such that actuation of the lock cylinder unlocks the lock mechanism.

A remote safety release comprises an actuator (13) adapted to move between a inoperative position wherein it does not interact with the locking mechanism of a switch and at least one operative position wherein it interacts with the locking mechanism, a remote control device (14) adapted to promote the movement of the actuator from the inoperative position to an operative position, a transfer mechanism (15) adapted to transfer a force from the remote control device (14) to the actuator (13) following the command given by the operator to promote the movement of the actuator (13) and adapted to exert a first solicitation on the actuator (13) to promote its automatic passage from the inoperative position to an operative position, while the remote control device (14) constantly exerts on the actuator (13) a second contrast solicitation opposite to the first solicitation and having at least equal value.

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

A transmission mechanism applied to a lock and for controlling the lock to switch between an unlocked state and a locked state. The lock includes a first handle set including a first cover plate which includes a first fitting portion. The transmission mechanism includes a transmission element and a moving component. The transmission element is connected to the first handle set in a manner that the transmission element is incapable of moving along a rotating axis and has an abutting portion. The moving component is disposed on the transmission element in a manner that the moving component is capable of moving along the rotating axis and includes a first engaging groove, a second engaging groove and a second fitting portion. When the transmission element is operated to rotate, the abutting portion is capable of switching between the first engaging groove and the second engaging groove.

A lock including a latch provided at one of a door and a cabinet, and a coupler provided at the other one of the door and the cabinet, the coupler including a housing including a latch insertion hole, an engaging lever including an engaging lever body rotatably provided within the housing, a latch insertion groove having a first end of the latch inserted therein by extending from a first end of the engaging part body, and first, second, third, and fourth projections formed by extending a second end of the engaging lever body.

An example lock apparatus generally includes a housing, a latch spindle, a drive spindle, an electronic lock mechanism, and an override mechanism. The latch spindle is mounted for rotation relative to the housing, and is operable to actuate a latch mechanism. The drive spindle is mounted for rotation relative to the housing. The electronic lock mechanism is disposed in the housing, and is operable to selectively couple the drive spindle with the latch spindle. The override mechanism is disposed in the drive spindle, and is operable to selectively couple the drive spindle with the latch spindle.

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.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.
