In an example, a system for preventing a flip door from being raised without a guardrail installed is disclosed. The system includes a guardrail having a post, and the post having a post dog. The system also includes a safety latch mechanism configured to be coupled to a fixed structure. The safety latch mechanism includes a body, a socket disposed in the body and configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to retain a flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.

A lock assembly comprising: a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein lateral movement of the hand-operable member causes the lock assembly to move between a locked mode and an unlocked mode. A lock assembly comprising: a latch, the latch configured to move rotationally relative to the lock assembly; and a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein the hand-operable member is coupled to the latch such that lateral movement of the hand-operable member drives rotational movement of the latch. Methods of installing a lock assembly, comprising setting a hub of a lock assembly to one of a first unlocked position, a first locked position, a second unlocked position, a second locked position, or a deadlocked position, and installing a cylinder lock for engagement with the hub.

Examples described herein relate to a latch for releasably coupling objects. In some such examples, the latch includes a receiver, a torque member, and a handle. The receiver includes a lobe to releasably engage an anchor point within a recess of the receiver. The torque member is rotatably coupled to the receiver to rotate the receiver. The handle includes a torque portion rotatably coupled to the torque member to rotate the torque member and includes a lever extending from the torque portion.

A rotary latch mechanism for releasably securing a first structure relative to a second structure. The rotary latch mechanism includes a housing adapted to be attached to the first structure, an actuator assembly coupled to the housing, a linkage coupled to the actuator assembly and arranged for movement along the housing with movement of the actuator assembly, and a bolt coupled to the housing and to the linkage, the bolt arranged for pivotal movement relative to the housing with movement of the linkage. The bolt is adapted to move between a latched position engaged with the second structure to secure the first structure relative to the second structure and an unlatched position spaced apart from the second structure to allow movement of the first structure relative to the second structure.

A lock assembly (30, 30′) is provided that includes a housing (32), a rotary bolt (36) or a translating bolt (36′), and a bolt blocker (38) that moves between a blocking position blocking movement of the bolts (36, 36′) and an unblocking position permitting the bolts (36, 36′) to move to a retracted position. The lock assemblies (30, 30′) are resistant to shocks being applied to the locks assemblies (30, 30′) in an effort to open the lock assemblies (30, 30′) without authorization.

The invention relates to a lock for a door or flap, comprising a locking mechanism that consists of a rotary latch (1) and at least one pawl (2) for locking the rotary latch (1), the rotary latch (1) when in the detent position preferably initiating an opening moment in the pawl (2). The design of the rotary latch (1) is such that said latch is deformed under excessive stress in the locked state in such a way that an engagement between the pawl (2) and the rotary latch (1) is maintained or increases. A lock of this type will not open even under excessive stress.

A vehicle door latch assembly is provided, the latch assembly having: a fork bolt movably secured to the latch assembly, the fork bolt being capable of movement between a latched position and an unlatched position; a detent lever movably secured to the latch assembly, the detent lever being capable of movement between an engaged position and a disengaged position, the detent lever retains the fork bolt in the latched position when the detent lever is in the engaged position and a engagement surface of the detent lever contacts an engagement surface of the fork bolt; and a spring member integrally formed with the detent lever, the spring member being deflected by a bumper secured to the latch assembly when the detent lever is moved to the engaged position.

A motor vehicle sliding door can be moved by a sliding movement between open and closed positions, wherein, in order to lock the sliding door in the open position, a mechanical door stop in the form of a locking latch which has a receiving region for a catch element of the sliding door is provided, and wherein the locking latch can be released by a motorized actuation device, whereby the catch element is released. In the event of failure of the motorized actuation device of the locking latch, for an intuitive unlocking and locking of the sliding door in the open position thereof may be achieved in that the locking latch has a resiliently loaded overload lever, in that the overload lever forms a lateral portion of the receiving region of the locking latch and in that, when the locking latch is locked, the overload lever can be pivoted outward when a specific pushing force of the sliding door is exceeded.
