A latch system has a pin movable along a pin axis, a control rod connected to the pin, a control wall comprising a control aperture comprising a lock hole joined to an unlock hole by a rod channel, and a control knob biased toward the pin, wherein the control knob comprises a lock tip sized to fit within each of the lock hole and the unlock hole.

A door arrangement includes a door leaf movable relative to a frame. A locking device in a locked state locks the door leaf to the frame by at least one locking element and in an unlocked state releases the door leaf relative to the frame. An actuating element selects the state of the locking device. To transmit a movement of the actuating element, the locking device has a connecting bar which is arranged displaceably on the door leaf, wherein a motor-operated drive unit for driving the connecting bar is provided. A sensor device for the contactless detection of a movement of the connecting bar is provided and the motor-operated drive unit can be activated in accordance with a movement of the connecting bar detected by the sensor device.

A double-door lock assembly includes a first lock and a second lock which are respectively mounted on a first door and a second door. The double-door lock assembly utilizes a first linkage member of the first lock to connect a second linkage member of the second lock to allow the first and second locks to co-operate. Hence the first and second doors can be opened or closed simultaneously in the same direction.

A fastener for highly curved access panels on aircraft or other structures, featuring a bottom-grasping design allowing for an unblemished outer panel surface, simple and rapid pneumatic fastener actuation, built-in clamping pre-load, and full retractability of the fastener inside the supporting structure. The fastener includes a Belleville spring with a piston centrally disposed therein, where the piston and spring deflect outward upon application of pneumatic pressure. A pressure chamber within the piston has inlet and outlet orifices designed so that the pressure in the piston chamber gradually increases, requiring several seconds to reach a pressure which causes locking dogs in the piston to deploy radially into a cavity in the access panel. When pressure is removed, the Belleville spring relaxes, the locking dogs grasp a lip of the cavity, and the access panel is latched onto the structure with a clamping pre-load. A pneumatic sequence for unlatching is also provided.

A door locking mechanism includes a main body, a trigger, and a slide lock. The slide lock and the main body are configured such that at least a portion of the slide lock extends outside of the main body in a locked position, with the slide lock being advanced into the main body as the slide lock transitions toward an unlocked position. A ball lock is in operative communication with the trigger and the slide lock, with the ball lock, the trigger, and the slide lock being configured such that when the trigger is in the extended position, the ball lock inhibits movement of the slide lock from the unlocked position toward the locked position. Movement of the trigger from an extended position toward a retracted position allows the ball lock to assume an unobstructed position allowing the slide lock to transition from toward the locked position.

A compression latch for a door includes a driver that is rotatable with respect to the door between an unlocked position and a locked position. The driver is configured to be mounted to one side of the door. A driver shaft is non-rotatably connected to the driver such that the driver shaft rotates along with the driver. In an unlocked position of the driver, the pawl is positioned to permit opening of the door, and, in a locked position of the driver, the pawl is positioned to prevent opening of the door. The compression latch is configured to translate the pawl closer toward the door upon rotating the driver from the unlocked position to the locked position.

A locking apparatus for a sliding closure slidable within a frame is disclosed. The locking apparatus comprises at least one locking tang movable transversely to the closure plane, between a locking position and a release position wherein, when in the locking position the locking tang extends laterally, in a direction transverse to the closure lane, beyond the closure to be received within a corresponding locking recess in the frame, such that the locking tangs resist opening of the closure, and when in the release position the locking tang is withdrawn within the dimensions of the frame, such that the closure may be opened or closed. The locking mechanism may also comprise a sensor configured to detect when at least one of the locking tangs are in the locked or released position, and, optionally to trigger an alarm if the locking tang is disengaged.
