The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).

Provided is a refrigerator including a body including a storage space; and a door configured to open or close the storage space, wherein the door includes a first door rotatably connected to the body by a hinge; a second door provided to be rotatable with respect to the first door; a magnetic member provided at the body; and a locking device provided at the first door and configured to interact with the magnetic member, wherein the first door and the second door are unlocked in a state where the first door is closed, and the first door and the second door are locked in a state where the first door is opened.

A locking module for selectively coupling a first component and a second component of a lockable device includes a housing and a magnet arranged within said housing. A locking element is movable relative to said housing between an unlocked position and a locked position. An engagement member is operable to selectively decouple said locking element from said magnet to move said locking element between said unlocked position and said locked position.

A lock assembly includes a lock element, and a lock housing including a receptacle for receiving therein the lock element. The lock housing includes a lock device that in a locked configuration is in locking engagement with the lock element and in an unlocked configuration is not in locking engagement with the lock element. A magnetic member magnetically holds the lock element in the receptacle against a force of gravity in the unlocked configuration.

A magnetic locking mechanism includes a first housing, a second housing, and an unlocking member. The first housing includes a guiding member including a first through hole. The second housing includes a locking member including a telescopic rod. The unlocking member is configured to adsorb the locking member. When the locking member is moved along the guiding member to a preset position, the telescopic rod protrudes into the first through hole, and the second housing is locked to the first housing. When the unlocking member adsorbs the locking member protruded into the first through hole, the telescopic rod retracts from the first through hole, and the second housing is unlocked from the first housing.

Disclosed is a locking device for an enclosure, such as a cabinet. The locking device includes a catch attached to the frame. The catch has a first portion provided adjacent to a surface of the frame, and a second portion extending from and generally perpendicular to the first portion. The second portion is provided adjacent to an end of the frame. The locking device further includes a latch attached to the movable component. The latch includes a locking arm having a projection adapted to engage with the second portion of the catch upon movement of the movable component away from the first portion of the catch. Such a shape of the catch may prevent failure of the attachment between the catch and the frame.

A touchless detent door lock is disclosed. In embodiments, the door lock includes a strike and a lock housing that defines a longitudinal cavity, where the strike can be linearly actuated within the longitudinal cavity from an unlocked position to a locked position, and vice versa. The door lock further includes at least one selector magnet coupled to or at least partially embedded within the strike and a plurality of position magnets coupled to or at least partially embedded within the lock housing. The position magnets include at least a first magnet corresponding to the unlocked position, a second magnet corresponding to the locked position, and a third magnet in between the first magnet and the second magnet. The first and second magnets are configured to attract the selector magnet, while the third magnet is configured to repel the selector magnet.

A latching apparatus and method for latching two separable apparatuses. The latching apparatus includes a moveable actuator and a bolt. The moveable actuator has a bolt facing north-pole magnet and bolt facing a south-pole magnet attached thereto. The bolt moves in response to the north-pole magnet and the south-pole magnet when the bolt is adjacent the actuator.

Provided is a magnetically fastening apparatus. The magnetically fastening apparatus includes a zipper tab and a lock body. The zipper tab can fit with the lock body by magnetic attraction. The lock body is provided with a control member. The control member has a locking position and an unlocking position. The zipper tab can fit with the lock body by magnetic attraction when the control member is in the locking position. The zipper tab and the lock body are configured to release the magnetic attraction relationship between the zipper tab and the lock body when the control member is in the unlocking position.

An elevator call box with internal, concealable latching mechanism comprises an internally disposed, cylindrical magnetic pin with a relatively low pull force that is slidably displaceable by an larger, external magnetic force supplied by a service technician. When the access door is closed, magnetic pin penetrates an orifice in a locking tab to lock the call box. The pin magnet is normally attracted to an adjacent, magnetically attractive clip snap-fitted to a latching block. The latch is externally disengaged via a stronger portable magnet carried by service personnel. The larger magnetic pull force of the portable magnet slidably displaces the smaller magnetic latch pin, freeing the locking tab to permit pivotal opening of the access door. Once the stronger magnet is moved away, the smaller magnetic pin, which is attracted magnetically to the clip, will return to it's rest position penetrating the locking tab and locking the control.
