A lockset and a pallet loading bin an associated lock hole. The lockset comprises a lock bar and a handle comprising a connection end. A lock bar is provided with a hook member to interlock with the lock hole and a connection portion. The lock bar is rotatably connected via the connection portion, to a bin body of the pallet loading bin. Rotating the lock bar around the connection portion parallel to an outer surface of the bin body causes the hook member to extend into or retract from the lock hole, thereby interlocking or releasing the lockset. The handle is rotatably connected via the connection end, to a second end of the lock bar opposite to the first end of the lock bar. Rotating the handle around the connection end positions the handle close to or away from the outer surface of the bin body.

Systems and methods for operating an aircraft door including an airstair are disclosed. In one embodiment, the system includes a hinge configured to pivotally couple a lower portion of the door to a fuselage of an aircraft, a lift mechanism and an interlock. The lift mechanism causes a movement of the door relative to the hinge between a lowered position and a lifted position. The interlock is configurable between: a locked configuration where the movement of the door relative to the hinge is prevented; and an unlocked configuration where the movement of the door relative to the hinge is permitted.

Provided are a lockset and a pallet loading bin having the same. A lock hole is arranged at the pallet loading bin. The lockset comprises a lock bar and a handle. A first end of the lock bar is provided with a hook member for fitting the lock hole to realize locking. A connection portion is provided at the lock bar. The lock bar is rotatably connected, through the connection portion, to a bin body of the pallet loading bin. Rotation of the lock bar around the connection portion in a plane parallel to an outer surface of the bin body causes the hook member to extend into or retract from the lock hole, thereby realizing locking or unlocking of the lockset. The handle comprises a connection end. The handle is rotatably connected, through the connection end, to a second end of the lock bar opposite to the first end of the lock bar. Rotation of the handle around the connection end causes the handle to be positioned close to or away from the outer surface of the bin body. The lockset has a simple structure and low costs, can be processed and manufactured easily, can be operated flexibly with less effort, and adapts to the small thicknesses of an end wall and a side wall of a pallet loading bin.

An equipment carrier holding device has a housing with a door. A screwing block is arranged in the housing. A clamping block and a fastening screw fix a fastening link of an item of equipment between the clamping block and the screwing block. The clamping block is positioned in relation to the door such that, in the event of incomplete arresting of the fastening screw, the fastening screw forms a mechanical barrier to complete closing of the door. A rail vehicle is also described which is equipped with such an equipment carrier holding device.

A handle (100), having: an escutcheon (106) having a recessed area (300); a lever (104) pivotally mounted toward the top end of the escutcheon and at least a portion of the lever is disposed within the recessed area when in a lever closed position (102); a first gear (310) operatively connected to a top side (312) of the lever and a portion of the first gear including gear teeth (320) extending through an opening (360) in the escutcheon; a second gear (324) mounted on a back (130) of the escutcheon and having cam teeth (322) that mesh with the gear teeth of the first gear; a cam latch (140) operatively connected to the second gear to rotate when the second gear rotates; and, a lock assembly (146) mounted to a bottom end (202) of the lever.

An electronic chassis includes a motherboard sled configured to engage in or out of the electronic chassis. The motherboard sled includes a housing and a mechanical actuator for engaging the motherboard sled into or out of an electronic chassis. The mechanical actuator includes at least one lever rotatably coupled to a hinge to form a first fulcrum adjacent to a vertical edge of a front surface of the housing. The mechanical actuator also includes a guiding arm adjacent to the hinge and mechanically connected to the at least one lever to form a second fulcrum. The guiding arm rotates between a secured position adjacent to the front surface and an unsecured position away from the front surface.
