A latch feature for a door includes an input body that is operable to move linearly between first and second positions relative to the door. The latch feature also includes an output body. The output body is coupled to the input body by a pivot member that is configured to pivot relative to the output body and the input body to allow the output body to move linearly toward the input body from an outboard position to an inboard position as the input body moves from the first position to the second position.

A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

A sliding door handle and strike assembly includes a locking member for engaging the strike to prevent the door from opening. The locking member is biased to an unlocked position, until it is moved into a locking position, in which magnetic co-operation acts to hold the locking member in the locking position.

The disclosure relates to a magnetic-actuation latch device. The magnetic-actuation latch device includes a housing, a latch element, a sliding plate, an elastic component, a rotating element and a limitation element. A lateral opening of the housing spatially corresponds a first magnetic block mounted on a fixed component. When a second magnetic block of the latch element is aligned to the first magnetic block, an actuation force is generated to drive the latch element to pass through the lateral opening and engage with the fixed component. The elastic component is connected between the sliding plate and the housing. When the rotating element is rotated by an external force, the sliding plate is driven to misalign the second magnetic block from the first magnetic block, and the latch element does not pass through the lateral opening. The limitation element is pivotally connected to the housing for blocking the rotating element.

A latch includes a housing that has a first side and a second side. The latch includes a bolt assembly that is positioned at least partially within the housing. The bolt assembly includes a bolt movable between an extended position and a retracted position relative to at least one of the first and second sides of the housing. The bolt is biased toward at least one of the extended position and the retracted position, and the bolt is positionable so as to selectively extend from either the first side or the second of the housing in the extended position.

The present application provides a lock (100) for a door. The lock comprises a housing (102), a lock mechanism (108), and a bolt (104). An end portion (112) of the bolt comprises a trigger (106). The lock mechanism is operable to move the bolt between a locked position in which the end portion extends through an opening in the housing and projects from the housing, and an unlocked position in which the end portion is within the housing. The lock further comprises a retraction mechanism (110), wherein actuation of trigger causes the retraction mechanism to automatically move the bolt from the locked position into the unlocked position.

A locking device for a lock including a box and a cover, such that the device can be isolated, which box includes therein a motor, a worm screw connected to the shaft of the motor, a locking shaft which is capable of sliding through a hole towards the outside of the box, and an elastic element with two ends, connecting the locking shaft with the worm screw, wherein one end of the elastic element is securely connected to the locking shaft and the other end is inserted between two threads of the worm screw such that, upon activating the motor, the worm screw rotates, moving the elastic element in order to drive the locking shaft, which transitions from being retracted to being extended and viceversa.

A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.

A shutter locking assembly that has a bolt carriage with a bolt slidingly engageable with the bolt carriage and a biasing (actuator) means operatively connected to the bolt member and the bolt carriage. The bolt carriage is inserted into a cavity of a shutter slat, and the action of moving the shutter slat between an up (open) position and a down (locked) position, causing the bolt to be moved between an extended position and a retracted position. When the shutter slat is in a down (locked) position the bolt engages with a bolt receiving opening adjacent to the shutter slat, and when in an up (open position) the bolt is retracted
