A track door system for an aircraft includes a door having a first side and a second side opposite the first side. A first roller track and a second roller track are aligned adjacent one another on the first side of the door. A third roller track and a fourth roller track are aligned adjacent one another on the second side of the door. A first motion driver is configured to move the door along the first roller track and the second roller track. A second motion driver is configured to move the door along the third roller track and the fourth roller track. A drive unit is operatively coupled to the first motion driver and the second motion driver to provide electromechanical power for cooperatively moving the door forward to an open position or aft to a closed position.

A vehicle opening and closing body driving device includes an annular driving belt including a coupling portion coupled to an opening and closing body of a vehicle and configured to be rotationally driven, and a guide frame having a sliding contact surface with which the driving belt is in sliding contact and extending in an opening and closing operation direction of the opening and closing body. The sliding contact surface is provided with a low sliding resistance portion having a plurality of recessed portions.

A slide door driving device includes a support plate that is an elongated plate member, two driven pulleys supported respectively by opposite ends of the support plate in a longitudinal direction of the support plate; a belt wound around the two driven pulleys; a connector by which the belt is connected to the slide door; and a driving portion supported by the support plate and configured to drive the belt.

A device comprises a linear guide with a first rail and a second rail and being mounted onto the cabin along an upper face thereof; a further guide having a linear portion being parallel to the linear guide and an inclined portion extending transversely to the linear guide; a moving part having a first slide which slidebly runs along the linear guide and a second slide which slidebly runs along the further guide and being displaceble with respect to the first slide from a retracted position to an extracted position or vice versa and being connected to the door by means of a connecting element; the first slide comprising two sliding means running on the first rail and the second rail respectively; a space being defined between the sliding means allowing the second slide to be guided along the further guide;

A sliding door device for a vehicle includes a door panel for opening and closing a door opening and covered by an upper trim and a lower trim, and a center rail mounted on the door panel to extend in a longitudinal direction of the vehicle body and providing a path for a center roller mounted on a center portion of the vehicle body, wherein a lower portion of the upper trim and an upper portion of the lower trim are disposed to overlap each other vertically. The center roller is mounted on a center roller mounting bracket including a first surface extending toward the vehicle body to be vertical to the door panel, a second surface bent from the first surface toward a lower side of the vehicle body, and a third surface extending from the second surface toward the vehicle body to be vertical to the door panel.

A door opening assembly is provided for moving a door of a vehicle between an open position and a closed position. The assembly includes a frame member coupled to the vehicle, a link is coupled to the frame member, and a link arm pivotally coupled to the link. A pivot arm is pivotally coupled to the frame member and a pivot bracket is pivotally coupled to the door and the pivot arm. The pivot bracket includes a slot such that a pin on the link arm slides therethrough. The assembly includes a gear rack and a gear operably coupled to the gear rack. The gear is driven by a motor as the door moves between its open and closed positions. The assembly further includes a guide track coupled to the vehicle and a roller rotatably driven along the guide track as the door moves between its open and closed positions.

A vehicle has a sliding door fitted with a rotatable brake member to apply a braking force to the sliding door when the vehicle is on a slope. The brake member is automatically rotated about a pivot axis X-X by a moveable member forming part of an actuator when the vehicle is resting on a slope into a position in which a braking force is applied to the sliding door by the interaction of the brake member with an elongate track in the form of a sliding door support track.

A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to a closing cable a part of which is wound around the rotating drum and that is hung on a closing inversion member and an opening cable a part of which is wound around the rotating drum and that is hung on an opening inversion member. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. An outer diameter of the rotating drum of the drive device is made smaller than a maximum diameter of a deceleration mechanism for making the rotating drum rotate forward and backward.

To provide a power slide window in which the projecting dimension of the guide rail from the panel surface is small, the guide rail (4) defines a pin guide groove (26) that includes a groove main portion (26a) extending along a panel surface (2b) and at least one groove extension portion (26b) configured to drive a slide panel (3) in a direction to approach the window glass pane (2) via a pin (16) when the slide panel reaches the vicinity of the closed position. A slider guide groove (27) provided in the guide rail 4 to allow sliding of the slider 20 which is slidingly driven in the opening and closing direction and a groove main portion (26a) of a pin guide groove (26) are formed at least partially in common with each other.

There is described a door assembly for a bathing enclosure, comprising: a frame; a rotatable panel rotatably securable to a wall; and a slidable panel slidably secured to the frame, wherein a sliding motion of the slidable panel triggers a rotation of the rotatable panel, wherein the door assembly is movable between an open position and a closed position, wherein when the door assembly is in the closed position, the rotatable and slidable panels are adjacent to one another and are unparallel and wherein when the door assembly is in the open position, the rotatable and slidable panels overlap one another and are parallel together.
