A cover device, includes a movable cover configured to cover retaining jaws of a retaining jaws module; a retaining cover connected to a side wall frame of a vehicle body and configured to enclose in the shape of a U an insertion end side of a retaining jaws module for insertion of a striker plate module to releasably couple with the retaining jaws module so as to connect a vehicle door with the side wall frame, and adjacent longitudinal sides of the retaining jaws module in transverse direction of the vehicle; and a rubber lip configured to elastically connect the retaining cover to the retaining jaws module and to compensate for tolerance compensation.

A sliding latch replaces a prior art door strike plate. The sliding latch has two components, a strike plate and a sliding latch cover reciprocal within the strike plate. A handle protrudes from the sliding latch cover sufficiently to extend beyond a closed door and door frame, to permit the handle to be manually grasped and lifted in a crisis. When the sliding latch cover is thus elevated, it no longer blocks the door bolt, allowing the bolt to extend farther and engage with the strike plate and extend into the door jamb, locking the door. One of the strike plate mounting screw holes is preferably drawn slightly out of the primary plane of the strike plate toward the jamb, and a pair of elevated distally located edges run longitudinally along the strike plate. The drawn screw hole and raised edges guide and limit motion of the sliding latch cover.

A lockcase is mountable upon a surface of a doorway jamb which is selectively closable by a barn door. The lockcase includes a bolt which translates or otherwise moves relative to the lockcase to selectively engage a strike in the barn door. The bolt is actuated by movement of a handle on a lever mounted to the lockcase. In one embodiment, the lever rotates to cause a shuttle to translate and with the bolt mounted to the shuttle. Detents on the shuttle tend to keep the bolt in either a retracted or a deployed position relative to the lockcase and the strike.

A cover device includes a cover that is displaced between a covering position where an upper side of a striker is covered, and an exposure position where the striker is exposed upward, and an open-close mechanism that displaces the cover to the covering position when a slide door performs an opening operation, and displaces the cover to the exposure position when the slide door performs a closing operation.

A locking system includes a lockcase which can be embedded within a recess in a jamb of a doorway. A barn door mounted outside of the doorway can be locked in the closed position by actuation of a lock mechanism within the lockcase. The handle interacts with the lockcase, causing a bolt to be translated out of the lockcase and into a strike in the barn door. The strike preferably passes entirely through the barn door, the strike including an outer entry which can be accessed via a key to push back the bolt and defeat the lock for emergency access. Cover plates and handles of different types can be provided for optimal performance. Lock mechanisms within the lockcase convert handle actuation into bolt translation between a collapsed orientation and a deployed orientation for locking the barn door.

A cockpit internal anti-sabotage system (CIASS) without compromising the cockpit security and the present anti-hijacking procedure and protocol, wherein a single cockpit crew alone in the cockpit cannot deny bonafide entry of other cockpit crew or cabin crew in an attempt to commit suicide or sabotage the aircraft, the system comprises a manual door lock system and an automated door lock system wherein both the systems comprising a mechanical system or a non-mechanical system or combination of both.

A retractable cover assembly is provided for a vehicle to cover a latching component such as the striker of a trunk door. The assembly includes a retractable cover and a support structure for supporting the cover at a position to cover the striker. The assembly further includes an arrangement for actuating the cover between an open position exposing the striker and a closed position covering the striker. A first light source may illuminate the cover and a second light source may illuminate an interior of the vehicle when the cover is in the closed position.
