A guide rail for a window lifter for raising and lowering a window pane or door system for a vehicle door having a carrier and at least two guide rails disposed on the carrier. The guide rails include a guide profile that can be twisted or bent for guiding an adjusting part of the window lifter coupled to the window pane along an adjusting direction predetermined by the guide rails and the guide profile includes a base and two legs protruding at obtuse draft angles from the ends of the base, such that the size of the draft angles is proportional to the bending or twisting of the guide rails prescribed by the kinematics of the retraction of the window pane over the adjusting travel of the window pane.

A window positioning apparatus for a vehicle comprising a window panel, a frame in which the window panel is guided between a closed position closing a window opening in the frame and an open position opening the window opening, and a multi-stage telescoping screw actuator mechanism connected between the window panel and the frame, the actuator mechanism being extendible to move the window panel from its open position to its closed position and collapsible to move the window panel from its closed position to its open position. The multi-stage telescoping screw actuator mechanism includes a plurality of screw members of progressively decreasing diameter respectively telescopically disposed within a next adjacent screw member of larger diameter. The plurality of screw members includes a first stage screw member that is rotatably supported and axially constrained in a housing fixed with respect to the frame, a last stage screw member attached to the window panel, and at least one intermediate stage screw member, and each intermediate stage screw member has internal and external threads respectively for engaging external and internal threads on next adjacent screw members, such that rotation of the first stage screw member in a first direction relative to the last stage screw member will cause the intermediate and last stage screw members to extend telescopically along an extension axis from the first stage screw member and rotation in a second direction opposite the first direction will cause the intermediate and last stage screw members to telescopically retract.

A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and closed positions relative to the discharge opening includes a dual position door control system. The system includes at least two controllers at spaced positions relative to the door and coupled to a drive mechanism for opening and closing the door.

A vehicle and a window assembly include a window movable between a closed and open position. The assembly includes an arm movable between a first and second position. The window is disposed in the closed position when the arm is in the first position and the window disposed in the open position when the arm is in the second position. The arm includes an extension fixed thereto such that the arm and the extension both move concurrently about a first pivot point. The assembly includes a connector coupled to the extension at a second pivot point. The arm is coupled to the window through the connector. The first and second pivot points are spaced from each other. The connector is coupled to the window such that movement of the arm moves the connector about the second pivot point which causes the window to move between the closed and open positions.

The present invention discloses a refrigerator and relates to the technical field of refrigerators. The refrigerator is invented to settle problems, such as increased external space occupied by a refrigerator when its secondary door is opened, increased difficulty in fetching goods in the refrigerator, and heavy loss of cooling capacity resulted from the full opening of an opening. The inventive refrigerator comprises a main door; an opening is formed on a door body of the main door; a guide rail is provided at an edge of the opening, and a secondary door is fitted on the guide rail; and the secondary door is connected with a driving mechanism which can drive the secondary door to slide along the guide rail, and as the secondary door slides along the guide rail, the secondary door can enclose or open the opening. The refrigerator of the present invention is used for preserving and freezing foods.

A window regulator assembly of a motor vehicle includes a guide rail on which a slide shoe is longitudinally movably mounted. The slide shoe has a main bracket which is mounted on the guide rail, and has a clamping arrangement. The clamping arrangement includes a clamping bracket connected to the main bracket and includes a pressure plate disposed parallel to the clamping bracket. A clamping component is clamped between the clamping bracket and the pressure plate. The clamping component holds a window pane. The clamping component has a holding surface which is disposed parallel to the pressure plate and a spacing between the holding surface and the clamping bracket is adjustable. A slide shoe of a window regulator assembly is also provided.

A window regulator includes a bracket on which window glass is to be supported, a first arm with one end rotatably supported by vehicle member constituting door and the other end rotatably supported by bracket, a second arm with one end rotatably supported by the vehicle member and the other end rotatably supported by the bracket, and a drive member configured to drive the bracket, on which window glass is supported, by rotationally driving the first and second arms. A rotation center shaft of one end of first arm and a rotation center shaft of one end of second arm are shifted in drive direction of bracket on which window glass is to be supported. A rotation center shaft of other end of first arm and a rotation center shaft of other end of second arm are shifted in drive direction of bracket on which window glass is supported.
