A door hinge apparatus of a vehicle may include a main bracket provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and having slide slots formed on upper and lower plates, respectively, a slide hinge bracket engaged to the slide slots to be slidable along the slide slots of the main bracket by a link mechanism, and a door hinge bracket Provided on the end portion of the door and pivotally connected to an external end portion of the slide hinge bracket through a hinge shaft.

A rolling device having a bearing housing accommodating a wheel axle carrying a wheel element, axle support members rotatably accommodated in the bearing housing and supporting the wheel axle, end portions of the wheel axle being connected to the axle support members in an eccentric position displaced from the rotational axis/4 line of the axle support members, a drive wheel connected to one of the axle support members for the axle support member to rotate following the rotation of the drive wheel, a first drive motor having a spindle engaged with the drive wheel to rotate the drive wheel and thereby the axle support member relative to the bearing housing, to displace the wheel element by eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.

An automatic door opening apparatus for a vehicle. Two and three hinge joint embodiments with motors at each hinge joint to control motion of the door opening apparatus relative to the vehicle at that hinge joint. The motors are individually programmable to customize the door opening apparatus and movement to different vehicles. The motors can be in alignment or out-of-alignment with the hinge joints, but in either case the motor controls motion of the hinged components at the associated hinge joint. When a motor is out-of-alignment with the hinge joint it controls, then pulley wheels and belts can be used to connect the motor to the hinge joint. The door opening apparatus can also include a floor track, and a door arm that connects the door to the floor track.

Systems and methods include providing an aircraft with a fuselage having a sliding door system disposed on at least one side of the fuselage. The sliding door system includes a forward sliding door having an upper slide rail and a lower slide rail, a rearward sliding door having an upper slide rail and a lower slide rail, an upper rail coupled to each of the upper slide rail of the forward sliding door and the upper slide rail of the rearward sliding door, a lower rail coupled to each of the lower slide rail of the forward sliding door and the lower slide rail of the rearward sliding door, and a plurality of actuators coupled to each of the upper rail and the lower rail and configured to displace and retract the forward sliding door and the rearward sliding door linearly with respect to the fuselage.

An item of furniture including a furniture carcass, a door wing movably-supported relative to the furniture carcass, and a furniture hinge for movably supporting the door wing, the furniture hinge being hingedly connected to the door wing. A receiving compartment is arranged in or on the furniture carcass for at least partially receiving the door wing, and the receiving compartment is defined by a sidewall of the furniture carcass. At least one cover is configured to be moved at least between a first operating position, in which the cover at least partially covers the receiving compartment, and a second position, in which the cover unblocks the receiving compartment. The furniture hinge includes a control member for moving the cover between the two operating positions upon an at least partial movement of the a door wing within the receiving compartment.

It is aimed to provide a railway vehicle plug door device capable of easily ensuring airtightness between a side structure body and a door leaf even if the railway vehicle plug door device is installed in a side structure body having a structure assembled by joining structural members by welding and including a bent part. A frame body is mounted on a part constituting an entrance in a side structure body by a mechanical fastening structure. A seal member is mounted on at least one of a door leaf and the frame body and held in close contact with both the door leaf and the frame body when the door leaf closes the entrance.

A spindle structure includes a lower rail mounted at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a lower guide rail mounted on the door and configured to form a lower guide route, and a spindle assembly positioned at one end of the lower rail, the spindle assembly including a spindle connected to a fixing unit fixed to the vehicle body, the spindle having one end rollably connected to the lower guide rail, having a threaded portion formed on an outer circumferential surface thereof, and being configured to be movable in a threaded manner between the vehicle body and the door.

The system comprises a lever (2) that is rotatable about a point fixed to the vehicle and articulately joined to the upper edge (6) of the leaf (1); a horizontal guide (3) through which a carriage (4) slides; push-pull means (10,11) that articulately link the upper edge (6) to the carriage (4); and actuation means (12) simultaneously linked to the lever (2) and the carriage (4), which are adapted to distribute their action on the lever (2) and the carriage (4) depending on the force to overcome in order to open and close the leaf (1), such that their action is automatically distributed on the lever (2) when greater power is required to move the carriage (4), this is essentially during the initial opening operation from the end closing position, and during the closing and locking operation from an imminent closing position.

A fastening arrangement for fastening a vehicle sliding door to a vehicle body while enabling opening and closing of the sliding door. The fastening arrangement includes a motion element configured for being movingly arranged within or on a vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, and a variable-length motion mechanism connected to the motion element and configured for being fastened to the sliding door at a lower attachment area of the sliding door. The variable-length motion mechanism is configured for enabling variable distance between the motion element and the lower attachment area of the sliding door.
