  • Patent number: 7841254
    Abstract: A gear-shifting safety device is provided for an all-terrain vehicle (ATV), including a gear lever, a gear-shifting hub shaft, a gear-shifting gear set, and a reversing bar. An end of the gear-shifting hub forms a step on which a block is provided. The block and the step form a stop face therebetween. The reversing bar has an end forming a stop section that is positionable on the step and is selectively in abutting engagement with the stop face so that to change to the reversing position, the reversing bar must be first actuated to disengage the stop section thereof from the stop face, allowing the switching fork to move to the reversing position on a position chute of the gear-shifting hub, thereby eliminating the damage of accidentally switching to reversing during the forward movement of the vehicle.

  • Patent number: 7828349
    Abstract: The resilient device contains two intermediate plates stacked and sandwiched between two outer plates. The intermediate plates have a center opening for accommodating a rotational seat and a spiral spring in the gap between the rotational seat and the intermediate plates. The ends of the spiral spring are attached to the rotational seat and the intermediate plates, respectively. An axle of a door knob or a door handle runs through the outer plates and engages a saw-toothed center opening of the rotational seat. When the door handle or door knob is turned, the spiral spring is tightened as the rotational seat is turned along with the door handle or door knob. When the door handle or door knob is released later, the spiral spring expands and therefore restores the door handle or door knob back to its original, un-turned state.

  • Patent number: 7823622
    Abstract: An ejection and stamping device is arranged at one side of an upper die of a vertical die casting machine and include a base on which first and second pistons are arranged. The first piston is coupled to a stamping board, while the second piston is coupled to an ejection board. When a casting of a die casting process is not completely solidified, the first piston drives the stamping board to carry out a localized stamping operation of a portion of the casting and then the second piston is operated to drive the ejection board for ejecting out the casting. In this way, local density and strength of the casting are enhanced and the product quality of the casting is notably improved.

  • Patent number: 7823259
    Abstract: A fast looping-up and releasing rope loop assembly includes two one-way locking devices, at least one band, and a buckle. The one-way locking device includes a body constituted by a base and a cover. The one-way locking device allows the pull rope to extend therethrough and to move with respect thereto along a single direction. By inserting the pull rope through a rope entry opening of the base of the one-way locking device and further extending the rope around a rotary disk and a rotary wheel arranged inside the locking device and extending out of the locking device, the one-way locking device that locks the movement of the rope in an opposite direction is completed. When the rope is jammed due to excessive tightening, a presser of the buckle is depressed to release the one-way locking device from the jamming condition so that efficient loop-up and release can be realized.
