A tailgate opening assembly includes a tailgate that is hingedly coupled to a trailer. The tailgate is positionable between a closed position and an open position. A pair of biasing members is each coupled to the trailer. Each of the biasing members is biased into a compressed position and each of the biasing members is stretchable into a stretched position. A plurality of pulleys is each coupled to a respective one of the biasing members and the trailer. A pair of cables is each of the cables is routed through respective ones of the pulleys and the tailgate such that the tailgate is in mechanical communication with each of the biasing members. Each of the biasing members assists a user with opening and closing the tailgate.

The present disclosure is directed to overhead doors and overhead door operation. More specifically, the present disclosure relates to a direct drive counter balancing system for operating overhead doors. In some examples, the direct drive counter balancing system of the present disclosure is for overhead door systems used in segmented door arrangements for box trucks.

A vehicle sliding door system includes a door portal and a door opening, at least one sliding door with an, in the closing direction of the sliding door, vertical front lateral edge and an, in the closing direction of the sliding door, vertical rear lateral edge, and a door driving unit for displacing the sliding door. The door driving unit has a cable, which, with its first end, is attached to the sliding door in the region of the front vertical lateral edge, and with its second end in the region of the rear vertical lateral edge, a coupling member, connected to the cable and which is connected to a motor, which is attached on the door portal laterally next to the door portal and which drives the coupling member such that the cable is movable along its longitudinal extent in both directions of movement and displaces the sliding door.

A trailer-based mobile observatory is provided that has a roof that is stable under gravity in the both the opened and closed positions to ensure better mobility and robustness for travel while eliminating the risk of the roof opening during travel. This ensures that if there is any mechanical failure while the roof is in the closed position, the roof will remain closed. The trailer-based mobile observatory enclosure can be designed to house one or more telescopes and to enable remote and robotic operation. The enclosure is designed for easy deployment and reliable operation with much thought put into possible failures and ensuring that any failure that occurs does not put the telescope and instruments at risk.

A vehicle door window glass support structure includes: a sash part protruding upward with respect to the door panel; and window glass that is elevated or lowered along the sash part, in which the sash part includes a glass position regulating means that determines the position of the window glass in both vehicle interior and exterior directions and an intersecting direction that intersects the vehicle interior and exterior directions at least at a position where the window glass is elevated most. This configuration makes it possible to improve the position accuracy of the window glass with respect to the sash part, enhancing the appearance quality and the support performance of the window glass.

An opening and closing body drive device for a vehicle includes a belt frame, plural driven pulleys, a belt wounded around the plural driven pulleys and fixed with a connector with respect to an opening and closing body, a drive unit provided with an output shaft including a rotary axis which extends in a different direction from a rotary axis of each of the plural driven pulleys, and a drive pulley connected to the output shaft of the drive unit. The drive pulley includes a rotary axis extending in the different direction from the rotary axis of each of the plural driven pulleys while extending in the same direction as the rotary axis of the output shaft. The drive pulley is wound with the belt which is twisted between the driven pulleys arranged at opposing sides of the drive pulley in a circumferential direction of the belt.

A pulley stud for a window regulator is provided. The pulley stud having: an upper head portion; a shaft portion; a first mounting portion; and a second mounting portion, wherein the first mounting portion has an anti-rotation portion located on a portion of the periphery of the first mounting portion.

A door tensioning system for an oven or other appliance includes a chain and spring assembled as a pull member attached at one end to a door and at an opposite end to a base member of the appliance in a manner maintaining spring-mediated tension between the door and the base/bulk of the appliance. The pull member is routed around a bracket-assembly-mounted pulley, where the bracket assembly includes at least one movable bracket member that is movable with the pulley in a manner that will increase or decrease tension in the pull member by increasing/decreasing its effective length between its ends.

Devices, systems, and methods for a frame with a slidable segment are disclosed. The slidable segment is slidably mounted within the frame. A first motor is coupled to the slidable segment. A first pulley is affixed to and driven by the first motor. A first end of a first wire is affixed to a first vertical member of the frame. A second end of the first wire is affixed to a second vertical member of the frame. The first wire wraps around the first pulley at least once. Driving the first pulley in a first direction causes the first pulley to pull on the first vertical member such that the slidable segment slides towards the first vertical member. Driving the first pulley in a second direction causes the first pulley to pull on the second vertical member such that the slidable segment slides towards the second vertical member.

A window regulator for a motor vehicle includes a drive unit assembly with a module plate. The drive unit for the window regulator includes a cable drum housing with a cable drum and a motor assembly. The cable drum housing includes a stepped annular ring extended from the cable drum housing and a snap-fit post protruded from each of the stepped annular ring for engaging with the module plate. The cable drum housing is positioned on a receiving site of the module plate, and the stepped annular ring and the snap-fit post is coupled with a locating site on the receiving site. Each locating site includes a circular bead for engaging with the stepped annular ring of the cable drum housing.
