A motor vehicle lock, in particular for a vehicle rear door, having a lock cover and a locking mechanism consisting essentially of a rotary latch and at least one pawl, also comprising at least one coupling element, and at least one electric drive, wherein the coupling element can assume different positions, and the coupling element interacts with a drive element of the drive and a central locking mechanism, wherein the coupling element is connected to the drive element in order to take up its positions.

A lockable latch (8) is disclosed for walk-in cold rooms which includes a lockable strike (10) with an exterior strike assembly (16) and an interior release assembly (17). The exterior strike assembly includes a housing (25) and a rod holder (32) configured to releasably hold a coupling rod (35). The exterior strike assembly also has a metal anti-rotation plate (40) removably coupled to the housing. The interior release assembly includes a turn knob (53), an escutcheon plate (54), and an index washer (55). The turn knob includes two oppositely disposed alignment projections (77) and a radial array of steps (78) which includes four, re-occurring series of three steps. The index washer has a four time re-occurring series of steps (93).

The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.

The disclosure relates to handle mechanism and casing assembly. The handle mechanism is adapted to be installed on a slidable plate body. The handle mechanism includes handle component, latch component, and releasing component. The handle component has engaged position. The handle component includes first hook portion and first pushing portion. The first hook portion has first contact surface. The latch component is slidably disposed and has second hook portion and first contact portion. The second hook portion has second contact surface configured to contact the first contact surface. The releasing component is pivotably disposed and has pressed portion and second pushing portion. When the handle component is pivoted from the engaged position, the first pushing portion pushes the pressed portion so as to force the second pushing portion to push the first contact portion so that the second contact surface is forced to leave the first contact surface.

A lock device is provided. The lock device includes a housing with a front opening at an end; a rotating hook disposed in the housing and being rotatable relative to the housing, the rotating hook including a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion; a driving device disposed in the housing and selectively moveable to change widths by which the front-end portion is opened respectively; and a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device.

A latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on/off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on/off positions to the other.

A motor vehicle lock, in particular for a vehicle rear door, having a lock cover and a locking mechanism consisting essentially of a rotary latch and at least one pawl, also comprising at least one coupling element, and at least one electric drive, wherein the coupling element can assume different positions, and the coupling element interacts with a drive element of the drive and a central locking mechanism, wherein the coupling element is connected to the drive element in order to take up its positions.

A lock device is provided. The lock device includes a housing with a front opening at an end; a rotating hook disposed in the housing and being rotatable relative to the housing, the rotating hook including a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion; a driving device disposed in the housing and selectively moveable to change widths by which the front-end portion is opened respectively; and a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device.

A mechanical clutch for mechanically connecting and disconnecting a rotational drive member and a rotational driven member of a locking mechanism. The mechanical clutch includes a drive and a driven member for rotation around an axis of rotation, a clutch pin which engages with the drive and or driven member to mechanically and rotationally link the drive and driven member to one another, and a clutch pin engagement surface provided on the or each clutch pin. A corresponding clutch pin engagement surface is also provided on the drive or driven members such that, when the engaged drive and driven members are rotated against a magnitude of rotational resistance (which is below a threshold magnitude of rotational resistance) the respective clutch pin engagement surfaces of the clutch pins and drive or driven members will co-act with one another to retain said rotational connection between the drive and driven member. When the drive and driven members are rotated against a magnitude of rotational resistance (which is above the threshold magnitude of rotational resistance) the respective clutch pin engagement surfaces of the clutch pins and drive or driven members will co-act with one another to urge the clutch pins out of rotational driving engagement between the drive and driven member.

A self locating tie bar guide for use with a tie bar. The tie bar guide defines a passage into which the tie bar is received. A tie bar receiving portion is shiftable between an open orientation in which the tie bar can be inserted into the passage and a closed orientation in which the tie bar is held in the passage. A resilient engaging member that engages a prelocated opening in the tie bar is resiliently biased toward the tie bar when the receiving portion is in the open orientation. The resilient tie bar engaging member is shiftable away from the tie bar when the receiving portion is in the closed orientation by contact between a portion of the resilient engaging member and another portion of the tie bar guide.
