A latch arrangement may comprise a latch bolt configured to rotate about a pivot, and a shear pin coupled to the latch bolt. A counterbore may receive the shear pin whereby lateral loads may be transferred between a door panel and a frame.

A latch mechanism includes a hook, a displaceable handle, and links connected between the handle and hook for the operation of the latch mechanism. The handle and links cooperate with the hook to hold the latch mechanism in a locked position.

A latch includes a latch housing including a first housing portion and a second housing portion separable from the first housing portion. The second housing portion includes a keeper. A first arm member is in rotational communication with the first housing portion. The first arm member is configured to rotate about a first axis between a first position and a second position. A second arm member is in rotational communication with the first arm member. A latch load pin is in rotational communication with the first arm member about a second axis. The latch load pin is configured to mate with the keeper with the first arm member in the first position. The second arm member in the first position is configured to be fixed relative to the first arm member as the first arm member rotates from the first position toward the second position.

A latching system for releasably securing a first structure relative to a second structure. The latching system includes a latch assembly coupled to the first structure and a keeper assembly coupled to the second structure. The latch assembly is selectively engageable with the keeper assembly to hold the first structure against movement relative to the second structure.

A locking device can be embedded flush into a surface and is intended for locking flaps of an aircraft. The locking device includes a plate and a locking element, which is actuatable thereby. In a locked state of the locking device, the plate is flush with the surface and, in an open state, the plate projects from the surface. At least some faces of the locking device, which are situated on an inside with respect to the surface in the locked state and are visible only in the open state, are coated with photoluminescent material.

A latch mechanism configured to engage a mating pin is disclosed. In various embodiments, the latch mechanism includes a latch frame; a latch arm pivotally mounted to the latch frame at a pivot axis; and a bias member configured to apply a load to the latch arm in a transverse direction generally perpendicular to the pivot axis and to bias the latch arm from rotating in a first rotational direction about the pivot axis and from rotating away from the mating pin.

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.

The present invention relates to a locking device (10), comprising a threaded rod (12) and a tapping tube (14), which are movable relative to each other. An outer surface of the tube includes a first anti-rotation form.

The device further comprises: a locking sleeve (16) positioned around the rod and comprising a second anti-rotation form (60, 62) capable of being assembled to the first anti-rotation form; and an elastic element (18) connected to the locking sleeve.

In a locked position, the first (38, 40) and second (60, 62) anti-rotation forms are assembled; and in a release position, said anti-rotation forms are axially spaced apart, whereby the tube is free to rotate relative to the sleeve.

A latch including a housing having a cylinder, a compression spring positioned within the cylinder, and a ball positioned at one end of the compression spring, a hook positioned slidably within the housing, and a star wheel positioned around the hook and having a plurality of holes formed therein. The ball under load from the spring aligns with and engages one of the holes of the star wheel to retain it in place. The star wheel is moveable rotatably such that the ball disengages the one of the holes of the star wheel to enable the hook to move axially and be adjusted relative to the housing, and the ball is adapted to engage another of the holes of the star wheel to retain the star wheel and prevent inadvertent rotation.

There is provided a latch indication system for a fan cowl of an air vehicle. The system has a door movable between a closed position and an open position, and has a handle movable between a handle stowed position and a handle deployed position. The system has a linkage assembly mechanically connecting the handle to a cover assembly. The cover assembly has a movable member movable between a movable member stowed position and a movable member deployed position, such that when the door is in the closed position and the handle is in the handle stowed position, the system indicates that one or more latch assemblies of the fan cowl are in a latched condition, and when the door is in the open position and the handle is in the handle deployed position, the system indicates that one or more of the latch assemblies are in an unlatched condition.
