Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

A semi-trailer structure swinging door system having one or more doors capable of swinging on double pivoting joints such that said door or doors can be opened both outward of the cargo containment structure and inward into the cargo containment structure. Various aspects of the joint provide for the joint as an insert and the joint having a sigmoid shape construction; the doors are capable of being secured by a latching mechanism in a closed position.

A locking device includes a lock portion on one of a fixed body or an opening/closing body, a rod on the other member, and a protrusion protruding from the other member. The rod has a recess surrounded by a pair of first walls facing each other in a sliding direction of the rod and a pair of second walls facing each other in a direction orthogonal to the sliding direction. A first elastic piece extends from one of the first walls toward the other and applies an elastic force against a tip end surface of the protrusion, and a pair of second elastic pieces extend from the second walls. Each of the second elastic pieces has a receiving surface that engages with a back surface of a flange portion of the protrusion, and is configured to elastically abut against a side surface of the protrusion.

A lock cassette includes at least one lock bolt connecting piece, adapted for releasable engagement with a lock cassette engaging end portion of a door integrated lock bolt of a door when the lock cassette is mounted in a lock cassette receiving cavity of the door, a lock bolt maneuvering mechanism, configured to displace the at least one lock bolt connecting piece between an extended position and a retracted position, to thereby displace the lock bolt between an extended position and a retracted position, and at least one lock bolt locking arrangement, configured to lock the movability of the at least one lock bolt connecting piece when a locking action is effected, and unlock the movability of the at least one lock bolt connecting piece when an unlocking action is effected.

The object of the present invention is a motor vehicle door latch, in particular a motor vehicle tailgate latch. In its basic construction, this comprises a plastic base plate (3) having a recess (13) and a drive unit (11, 12) arranged in the recess (13) Furthermore, a lever arrangement (4, 5, 6) acted on by the drive unit (11, 12) consisting of two or more levers (4, 5, 6) mounted on the base plate (3) is provided for. According to the invention, the levers (4, 5, 6) are detachably connected by means of a ratchet rotational connection (15, 16) and additionally axially secured by an individual attachment element (14).

Provided is a lock device for an opening/closing body, the device enabling a base member to be mounted from the front side of a mounting hole, and making it difficult for the base member to become loose. The lock device 10 comprises a lock part, a lock member which is operated via a manipulation member 40 in order to attach to/detach from the lock part, a mounting hole 6, and a base member 20 which is mounted by being inserted from the rear side of the mounting hole 6 and has a rotation support part 29 that rotatably supports the manipulation member 40, wherein: the manipulation member 40 comprises a base end part 41 and a grip part 42; a hook 26 is provided on one end side of the base member 20, the hook 26 engaging with the rear-side peripheral edge at the side at one end 6a of the mounting hole 6; and the base member 20 is provided with elastically deformable elastic engaging claws 30 which engage with the rear-side peripheral edge of the mounting hole 6 and are provided on the base member 20 further to the other end side, that is at the other side to the one end side, than the rotation support part 29.

A locking system for locking a closure element, more particularly a door, having a main body, which rotatably receives an actuation element, for arrangement on one side of the closure element and having a locking module for arrangement on the opposite side of the closure element. The actuation element has an interface for connection to the locking module. The main body has a fixed interface for connection to the locking module; and depending on the type of locking module, same can only be connected to the co-rotating interface or to both interfaces. The disclosure also relates to a closure element having such a locking system, and a method for assembling a locking system.

There is provided a locking device for an opening and closing body, including: a locking portion; a base; a rotation body that includes a protruding portion on a part of an outer periphery thereof; a locking member; and an elastic member that includes a base portion, and a stopper portion configured to restrict a maximum rotation position of the rotation body in a predetermined direction by abutting against the protruding portion of the rotation body. The stopper portion is disposed in a manner of being biased in a direction opposite to the predetermined direction relative to the base portion. A part of the outer periphery of the rotation body is provided with a sliding contact portion that is configured to come into sliding contact with the elastic member in a process in which the protruding portion approaches the stopper portion.

A multipoint lock assembly for a swinging door panel includes a mortise housing that is installed in a mortise along the non-hinged edge of the door panel. A latch operating mechanism and a lock operating mechanism are disposed in the mortise housing. Each of these mechanisms is designed to be operated with a standard rotary operator such as a handle or knob for the latch operating mechanism and a key and/or thumb turn for the lock operating mechanism. The latch operating mechanism is transitionable between left- and right-hand orientations and includes a deadlatch feature that prevents forced back-drive. Turning the key and or thumb turn of the lock operating mechanism extends a deadbolt and extends upper and lower shoot bolts from edges of the door. When extended, the shoot bolts also are secured against forced back-drive by unique mechanism configurations.

A latch system for a tonneau cover. The latch system includes a handle that is configured to move about an axis; and a latch pin connected to the handle. The latch pin is configured to move in a retracted direction and during movement of the handle towards the tonneau cover.
