A counter balance device for a sash window includes a spiral balance having a hand-wound spiral rod connected to wind a torsion spring to generate an initial spring force that counter balances the window's weight for keeping the sash up when raised. The lower end of the spiral rod is connected to a rotation shaft rotatably disposed on a slide block. When a large repulsion force produced by the torsion spring is applied to the spiral rod, the rotation shaft is urged in a direction reverse to the rotation direction of the spiral rod by a buffer spring having a spring force which is larger than the initial spring force so that the rotation of the rotation shaft is tolerated.

A sliding golf cart windshield assembly includes a first elongated rail, a second elongated rail spaced apart from the first elongated rail, and an upper windshield pane having a first longitudinal edge and an opposing second longitudinal edge. The upper windshield pane is slidably positioned between the first and second elongated rails. The assembly also includes a lower drive pulley, an upper drive pulley, and a drive belt stretched between the lower drive pulley and the upper drive pulley. In addition, the assembly includes a drive panel slidingly engaged with the second rail and secured to the upper window pane and the drive belt, and a motor coupled to the lower drive pulley and configured to rotate the lower drive pulley to raise and lower the upper windshield pane.

A furniture fitting includes at least one rotatably mounted screw for fixing the furniture fitting to a furniture part. The furniture fitting further includes at least one drive element separate from the screw, and the drive element is movement-coupled to the screw and has a tool receiving device. The at least one screw is configured to be driven by rotating the tool receiving device with the aid of a tool.

The invention relates to an assembly (1) comprising a housing with a balancing spring break protection mechanism, said assembly (1) being configured for connecting a connector (15, 42), such as a bayonet connector, of a balancing spring of a sectional door system to said assembly, said housing being for connection with a fixed structure and comprising a first housing plate (5) comprising an opening (16) for receiving a balancing axle (60) of said sectional door system, said balancing axle (60) being connected to said balancing spring, and an aperture (11) for receiving said connector (15, 42), said spring break protection mechanism comprising a bearing and ratchet wheel unit (4, 7), said ratchet wheel (4) including a shaft (50) for receiving said balancing axle (60).

A hood hinge assembly for a vehicle hood includes a support bracket and a hinge arm. The support bracket is configured to be fixed to a vehicle body structure. The hinge arm is movably connected to the support bracket. The hinge arm is movable about a pivot axis between a first position in which the vehicle hood is closed and a second position in which the vehicle hood is fully open. A stop tab is connected to the support bracket. The stop tab prevents movement of the hinge arm beyond the second position.

A system for remotely opening an access hatch of storage tank includes an elongate arm having a proximal end configured to be operatively coupled to a lid of the access hatch and a distal end extendable past an outer perimeter of the storage tank, and a pull cable attached to the arm at the distal end and being extendable toward a ground surrounding the storage tank. Pulling on the pull cable releases a latch that secures the lid to a base of the access hatch and allows the lid to pivot from a closed position to an open position.

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 tool assembly designed to couple to a torsion spring and torsion rod to wind and unwind the torsion spring on the torsion rod. The tool assembly includes a variety of components in mechanical communication with one other to rotate the torsion spring. Specifically, the assembly includes a worm gear in mechanical communication with a ring gear and a set of brackets securable to a torsion spring. Between the ring gear and the brackets are a series of plates arranged and assembled on a base, providing a singular device within the assembly that a user can grip to manipulate a torsion spring in a safer manner than possible in the prior art. A drill or other device can couple to attachment points in mechanical communication with the worm gear to rotate the worm gear at a greater rate, thereby reducing the winding and unwinding time of the torsion spring.
