This application provides a vertical sliding window, including horizontal frame side edges, vertical frame side edges, and an opening sash, wherein the opening sash slides up and down along a guide rail on the vertical frame side edge. In addition, the vertical sliding window further includes a balance weight device and a balance weight traction cable. The balance weight device includes an enclosure, a rotating shaft partially disposed within the enclosure, a spiral spring whose two ends are respectively fixedly connected to an inner wall of the enclosure and the rotating shaft, and a cone pulley fixedly connected to the rotating shaft, wherein a tapered surface of the cone pulley is provided with a spiral groove. A lower end of the balance weight traction cable is fixedly connected to the opening sash, and an upper end thereof is fixedly connected to the cone pulley. When the opening sash moves from bottom to top, an elastic deformational force generated by the spiral spring enables the balance weight traction cable to be gradually wound into the spiral groove, and the elastic deformational force of the spiral spring is gradually reduced. Due to a mutual conversion between elastic potential energy of the spiral spring and gravitational potential energy of the opening sash, in the vertical sliding window provided in this application, an external acting force for dragging the opening sash to move up and down as well as energy consumption may be reduced.

A sliding golf cart windshield assembly includes a first elongated rail having a top end and a bottom end, and a second elongated rail spaced apart from the first elongated rail and having a top end and a bottom end. An upper windshield pane has a first longitudinal edge and an opposing second longitudinal edge, where the upper windshield pane is positioned between the first and second elongated rails. In addition, the assembly includes a first upper plate secured to the first longitudinal edge of the upper windshield pane and being slidable within the first elongated rail, a first lower hub coupled to the bottom end of the first elongated rail, and a first belt having a first end first end fixed to the top end of the first elongated rail and passes around the first lower hub to the second end that is fixed to the first upper plate.

An adjustable window regulator lift plate assembly for a vehicle window includes a base and a window holder. The window holder is secured to the base via a part-in-assembly fastener that extends through an aperture in the base and into an aperture formed in an inner leg of the window holder. The window holder may receive and secure a window, and the fastener may be inserted through the window holder and into a fastener plate disposed on an outer leg of the window holder. The window holder includes a curved inner surface on the inner leg, and the base includes a curved outer surface that contacts the inner leg. The window holder may be shifted and pivoted relative to the base. The fastener may be tightened to secure the window holder relative to the base in a desired pivoted position.

A window regulator includes a carrier plate, a guide rail, an ascending-side wire and a descending-side wire, a driving portion, and a turnaround portion. The driving portion includes a rotating drum, a reducer, and a driving motor including a yoke portion that is arranged to be adjacent to one side of the reducer in an orthogonal direction orthogonal to the ascending/descending direction. The guide rail is arranged so as to in the orthogonal direction overlap only the ascending-side wire fed out from a first wire feeding-out position at the one side of the rotating drum in the orthogonal direction toward the turnaround portion between the ascending-side wire and the descending-side wire fed out from a second wire feeding-out position at an other side of the rotating drum in the orthogonal direction toward the carrier plate.

A dock door assembly and a dock door assembly kit are provided for use in a dock door opening for installation in a warehouse. The dock door assembly comprises a pair of vertical tracks, with each vertical track configured to be attached to a wall along opposing lateral sides of the dock door opening. The dock door assembly also comprises a multiple, horizontal section door characterized by a vertical height when closed and mounted on the pair of vertical tracks. The dock door assembly further comprises a spring shaft assembly and a pair of headplates with each headplate having a U-shaped opening to receive each end of a torsion shaft. Further, the dock door assembly may comprise a pair of door cables and a pair of corner cable attachments connecting each door cable to the spring shaft assembly.

An adjustable roller support mechanism for mounting on a panel positionable with respect to an opening in a building structure to support the panel on the structure. The mechanism may comprise an adjustment assembly configured to be mounted on the panel. The adjustment assembly may comprise a case defining an interior and at least one roller for contacting the opening rotatably mounted on the case. The mechanism may further comprise an adjustment element configured to contact the panel at a contact surface and further configured to adjustably move the case and the at least one roller mounted thereon with respect to the contact surface to adjust the position of the at least one roller with respect to the panel when the adjustment assembly is mounted on the panel.

In example a panel for an overhead sectional door is provided. The panel includes a laminate core, a laminate skin, and a universal fabric hinge. The laminate skin is coupled to two opposing sides of the laminate core. The universal fabric hinge is coupled to the laminate skin to connect the panel to an adjacent panel of the overhead sectional door.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.
