A latch mechanism includes a latch having a first latch protrusion and a second latch protrusion, and a catch having a first catch protrusion and a second catch protrusion. The first catch protrusion engages the first latch protrusion in a first catch position. The second catch protrusion engages the second latch protrusion in a second catch position following release of the first catch position.

An aircraft cowl arrangement may comprise a first half, and a second half rotatable between an open position and a closed position, a first seal coupled to the first half, a second seal coupled to the second half, and a latch arrangement for preventing relative movement between the first half and the second half. The latch arrangement may comprise a tie rod comprising a first end coupled to the first half, a second end, and a frame having an opening for receiving the second end of the tie rod, a latch handle rotatably mounted to the frame, and a hook operably coupled to the latch handle, wherein the latch handle is configured to move between a first position wherein the hook is engaged with the second end of the tie rod and a second position wherein the hook is disengaged from the second end of the tie rod.

A door latch assembly, includes: a catch support assembly, the catch support assembly including a strike body having a pin receiving aperture therein; a catch arm assembly rotatably mounted to the catch support assembly; a latch pin positioned in the pin receiving aperture and movable between a retracted position and an extended position, the latch pin protruding above the strike body in the extended position to impede rotational movement of the catch arm assembly; and a first roller mounted to the catch arm assembly and configured to engage a first side of the latch pin in the extended position; and a second roller mounted to the catch support assembly and configured to engage a second side of the latch pin in the extended position. The latch pin includes a material having a hardness of 60 Rockwell C or more, the first roller includes a material having a hardness of 33 Rockwell C or less, and the second roller includes a material having a hardness of 60 Rockwell C or more.

A crate assembly includes a plurality of members defining an interior of the crate assembly, where the plurality of members includes a front, a back, a top, a bottom, a first side and a second side. A frame is formed in one of the plurality of members, the frame having a plurality of interconnected horizontal and vertical wires that define a door opening. A door is pivotally coupled to the frame about a pivot wire of the frame to move between an open position and a closed position. A latch assembly is pivotally coupled to a horizontal wire of the frame. The latch assembly includes a wire having a first end, a second end and a transverse portion, the wire forming a first portion defined between the first end and the transverse portion and a second portion defined between the second end and the transverse portion.

A door latch for a motor vehicle according to an exemplary aspect of the present disclosure includes, among other things, a pawl, a release lever, and a clutch selectively engaged by a magnetic field. Further, when the clutch is engaged, motion of the release lever is transmitted to the pawl via the clutch. A method is also disclosed.

An exemplary closure system includes, among other things, a striker assembly, a latch assembly, and a hooked structure. In response to the striker assembly and the latch assembly being laterally displaced from each other, the hooked structure engages one of the striker assembly or the latch assembly to block separation of the striker assembly from the latch assembly. An exemplary latching method includes, among other things, engaging a hooked structure in response to a striker assembly being laterally displaced relative to a latch assembly. The engaging blocks the striker assembly from separating relative to the latch assembly.

The invention relates to a sliding security gate inside a framed pocket unit. These Pocket Sliding Security Gates can be assembled and installed inside of the wall and positioned to close off rooms, hallways, and/or stairs for the protection of babies and toddlers, pets, and the disabled elderly. The Pocket Sliding Security Gate can be placed during construction where it can close across openings or hallways at the top or bottom of the stairs to provide safety and security to the vulnerable population listed above. In addition, this Pocket Sliding Security Gate also has an alarm attached to the end of the security gate so that when it opens, the alarm sounds to let the gatekeeper know that the security has been compromised.

A cover member includes: a fittable recess that opens to one side of the cover member in a direction orthogonal to an axis of a shaft member, receives a torsion coil spring from the one side, and fits on an outer periphery of the torsion coil spring; and an anchoring counter element to which one end of the torsion coil spring is anchored. The torsion coil spring is engaged with a hook member while being fitted in the fittable recess, thus biasing the hook member toward movement about the axis of the shaft member to a locking position and supporting both ends of the shaft member rotatably around an internal surface of the coil to function as a bearing member.

Disclosed herein is a wrap-around gate latch assembly comprising a base frame formed by connecting together a front frame, a central frame, and a back frame. The base frame can be wrapped around a gate post for installation without drilling through the gate post. A moving plate is provided to communicate between a front part and a back part that are mounted on the base frame. A movable hook is provided in the front part, that engages or disengages with a striker bar in a latched or an unlatched position respectively. A first push button provided on the front part, is operated to disengage the hook from the striker bar for opening the latched gate. A second push button provided on the back part, is operated to push a single moving plate towards the front part thereby triggering the movable hook to release the striker bar.

A retention mechanism for a pair of bi-parting doors of a transit vehicle includes a first track connected to a first door of the pair; a second track connected to a second door of the pair; a first retention assembly connected to the transit vehicle and configured to retain the first track in the closed position; a second retention assembly connected to the transit vehicle and configured to retain the second track in the closed position; a first engagement member connected to the second track, the first engagement member being configured to engage the first retention assembly to cause the first retention assembly to move to retain the first track in the closed position when the second track is in the closed position; and a second engagement member connected to the first track, the second engagement member being configured to engage the second retention assembly to cause the second retention assembly to move to retain the second track in the closed position when the first track is in the closed position.
