Aircraft latch lock key

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.

Clevis-sensing adjustable hook latch

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

Key, lock, and latch assembly

Aircraft latch lock key head

A hinge is coupled to a first component and a second component. The hinge supports the second component for movement relative to the first component between a closed position covering an opening through the first component and an opened position displaced from the opening.

Lock apparatus

Clevis sensing lock

The present disclosure includes a tool operated channel latch used to secure a panel against a structure. The latch includes a bracket which mounts to a movable panel and includes an actuating mechanism to open and close the latch. A bolt is pivotably retained relative to the bracket for engaging against the structure closed by the panel. A lock assembly is carried on the actuator to engage a link which is movably coupled with both the bolt and the actuator. The lock assembly includes extending portions to engage at least one corresponding opening of the link. The link provides an over center toggle condition to retain the latch in a locked position until intentionally actuated by an operator.

Tool operated channel latch

A latching system for releasably securing a first member to a second member in a closed position. The latching system includes a command latch assembly comprising a hook latch assembly including a handle selectively moveable from a first handle position toward a second handle position and a hook member adapted to selectively engage a first keeper when the handle is in the first handle position and to disengage from the first keeper when the handle is moved to the second handle position. The latching system also includes a remotely located slave latch assembly comprising a pin latch assembly adapted to secure a second keeper to the pin latch assembly when the handle of the hook latch assembly is in the first handle position and to disengage the second keeper when the handle of the hook latch assembly is moved to the second handle position.

Command latch and pin latch system

A latch mechanism for releasably latching a first member to a second member. The latch mechanism includes a bracket adapted to be attached to the first member and bolt pivotally coupled to the bracket. A handle is pivotally coupled to the bracket and is operatively associated with the bolt such that the handle selectively pivots the bolt between a latched and unlatched position. A trigger is pivotally coupled to the handle and a locking member is pivotally coupled to the trigger. The locking member is adapted to releasably couple the trigger to the bracket to prevent pivotal movement of the handle and the bolt from the latched position. The trigger includes the tool receiving recess such that the latch mechanism may be moved between the latched and unlatched positions with the mechanical advantage provided by the tool.
