A sliding door driving device is fixed to a body panel of a vehicle and operates a sliding door of the vehicle in an opening direction and a closing direction. The sliding door driving device includes an elongated guide frame, a first driven pulley and a second driven pulley that are rotatably supported at both ends in a longitudinal direction of the guide frame, a belt that is wound around the first driven pulley and the second driven pulley, and a cover that covers the belt. The cover has an upper wall that covers the belt from above, an outer wall that extends downward from an outer end of the upper wall in a width direction of the vehicle, and an inner wall that extends downward from an inner end of the upper wall in the width direction.

According to some embodiments, a discharge door locking system for a railcar discharge door comprises a lock piston configured to move between a first position (not engaged with an operating beam coupled to a discharge door) and a second position (engaged). The locking system comprises a first and second input. Activation of the first input moves the lock piston to the first position, and activation of the second input moves the lock piston to the second position. The first input of the locking system is coupled to a first input of an operating cylinder coupled to the operating beam. The first input of the operating cylinder is configured to move the discharge door to the open position.

A vehicle door opening and closing apparatus includes a rail mounted on a vehicle body, a roller unit mounted on a vehicle door, the vehicle door having a main latch releasably engaged with a main striker mounted on the vehicle body, the roller unit configured to allow the vehicle door to open and close in a sliding mode and a swing mode, and an outside handle operatively connected to the main latch, and including a handle base mounted on the vehicle door and a handle grip movably mounted on the handle base, wherein the handle grip is slidable in a longitudinal direction of the vehicle body, and pivotal in a transverse direction of the vehicle body, and wherein as the handle grip slides, the sliding mode is selected, and as the handle grip pivots, the swing mode is selected.

Doors on a vehicle may be controlled by a door positioning system that moves the doors freely and fluidly relative to the body of the vehicle. The doors may include front and rear doors on each side of the vehicle. The door positioning system may control the movement and positioning of each door using a door mechanism coupled between the door and the body of the vehicle. The door positioning system may determine a position or path of motion for each door based on sensor data and user input. The door positioning system may issue corresponding control signals to actuators in the door mechanism to position the door accordingly. For example, the front door may slide open at an angle to accommodate an angled tire. Front and rear doors may open in opposite directions to create a large, unobstructed space for passengers to enter and exit the vehicle.

A sliding door includes a bar that is movable in the closing and opening direction of a door leaf the sliding door. When the sliding door is in a closed state, the door separates a first space from a second space. A door frame in which the door is mounted has a bar catch, wherein the bar engages in the bar catch when the door leaf is in the closed state. The engagement can be released by movement of the door leaf, and therefore movement of the bar, in the direction of the normal of the door leaf plane.

A retractable sliding door (10) with automatic alignment to the wall (12) during the closing phase, suitable to alternately open and close a through space (14) made along said wall, comprising a lower guide (18) fixed to the floor and an upper guide (20) forming a support beam. In the upper guide (20) paired prominences (50, 52) and (60) are made constituting the sliding tracks of two or more pairs of wheels (54) and single wheels (58) borne by a shaft (56) and combined with a frame (62) to form a carriage. The lower guide (18) interacts with a roller (24) suitable to fit into a shaped channel with a mixed-line extension (26) made along the lower head of the door (10); the upper guide (20) is provided with a shaped channel (78) having the same and parallel mixed-line configuration as said shaped channel (26). The upper head of the door (10) being provided with means for its suspension to the frame (62) constituting the carriage.

A fitting arrangement for a window or a door has a drive bar with a through-hole. A control pin and/or a counter element of the fitting arrangement is/are passed through the through-hole and connected to one another such that the control pin is captively retained on the drive bar. The control pin is preferably connected to the counter element without the use of tools. Particularly preferably, a spring element is provided which latches the control pin by pressing the control pin and the counter element axially together. The spring element can be designed in the form of a circlip which, in the not yet assembled state, is arranged on the control pin or the counter element.

A sliding door device for a vehicle, includes: a door that opens or closes a door opening formed in a vehicle body; a door arm provided with a first end portion rotatably connected to the door and a second end portion movable along a side sill of the vehicle body; a first slider pivotally coupled to the second end portion of the door arm so that the door arm rotates; a second slider coupled to the first slider to provide a path in which the first slider moves and to linearly move along the side sill; and a lower arm pinion gear which is rotatably coupled to the second end portion of the door arm and gear-engaged with the second slider to provide rotation force to the door arm so that the door arm rotates when the first slider moves in a longitudinal direction of the second slider.

A sliding door system for inline closure of an opening in the wall of a structure, which may be a building or an item of furniture, for example, that includes a door panel, a guiderail assembly, and a guiderail coupled to the wall mount via a plurality of doubled-hinge assemblies that together serve to allow the guiderail to pivot towards and away from the wall, and includes a stop on the guiderail that serves as a catch, or cam, that causes a closing force on the door panel to be transferred to the double-hinge assemblies and to cause the door panel to be pulled into inline closure in the opening.
