A tubular lock assembly has a tubular lock, a cover, and a disassembling unit. The tubular lock has an annular keyhole and a cover screw hole enclosed by the keyhole. The cover is detachably assembled with the tubular lock, and has a covering board segment, a screw rod segment, and a first fitting segment. The covering board segment covers the keyhole. The screw rod segment is detachably screwed in the cover screw hole of the tubular lock. The first fitting segment is formed on the covering board segment. The disassembling unit has a second fitting segment. The second fitting segment corresponds in shape and size with the first fitting segment of the cover, such that the second fitting segment is adapted to engage with the first fitting segment, and the disassembling unit is capable of rotating the cover.

A hinged door fixing apparatus comprises a fixed part and a holder part. The fixed part is fixed on a wall such that, in order to prevent the doorknob or edge portion of a hinged door from bumping directly against the wall in the process of opening the hinged door, a buffer member having a buffer ball coupled to the end thereof, which is mounted to the hinged door, comes into contact with the fixed part in the opening process. The holder part is installed in the fixed part and instantaneously holds the buffer ball through elasticity when the buffer member bumps against the fixed part.

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 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 door latch and a dishwasher fitted with a door latch are described. The door latch has a body, a pawl provided with a rotating shaft, a first gap being provided between two ends of the rotating shaft, and a mounting slot being provided in one side of the pawl, a first pin mounted on the pawl, the first pin being mounted in the mounting slot in the pawl, a spring having two ends which are connected to the body and the pawl, respectively, a first end of the spring being connected to the first pin through the first gap. During installation of the door latch, assembly of the door latch is quick and easy because the first pin is put into the pin mounting slot in the pawl from the top side of the pin mounting slot, and repair with changing of components is also easy.

A flapper door assembly for a vehicle is provided. The assembly includes a base comprising attachment features and a flapper door connected to the base via the attachment features and a first pivot axis to allow the door to rotate between open and closed positions, wherein the flapper door further comprises at least one cantilever spring integrally formed with the flapper door, wherein the cantilever spring comprises a beam and a second pivot axis offset from the first rod to bias the flapper door to the closed position.

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.

A vehicle includes a vehicle body that defines an opening, a vehicle door that is movable between a closed position and an open position with respect to the opening, a first surface, and a second surface. The first surface is defined on one of the vehicle body and the door and the second surface is defined on the other of the vehicle body and the door. A first latch portion is concealed behind the first surface. A second latch portion is concealed behind the second surface in an unlatched position and is movable to a latched position in which the second latch portion extends into the first latch portion and engages the first latch portion. A locking structure restrains disengagement of the second latch portion from the first latch portion in the latched position.
