  • Patent number: 12201892
    Abstract: Systems, apparatuses, and methods for fastening components of equipment, specifically a skateboard, among other types of sporting boards or sports apparatuses or wheeled sporting apparatuses. Fastening systems disclosed herein may be utilized to couple a deck of a skateboard to a truck of a skateboard. The fastening systems may reduce the need for a tool (e.g., a hex drive or other tool) that might typically be utilized to engage a head of a fastener to hold the fastener in place while a securement body (e.g., a nut) is coupled to the fastener.

  • Publication number: 20240115926
    Abstract: Systems, apparatuses, and methods for fastening components of equipment, for example, a skateboard or a roller skate, among other types of sporting boards, sports apparatuses, or wheeled sporting apparatuses. Fastening systems disclosed herein may be utilized to couple a skateboard truck to a skateboard deck. The fastening systems may add a high level of stability and durability to the coupling or the anchoring of, e.g., a kingpin to a baseplate on the skateboard truck. For example, the high level of stability and durability to the coupling or the anchoring may be achieved via a sleeve (e.g., a flanged sleeve) that is formed of high-strength material and press-fit into an aperture on the skateboard truck baseplate.

  • Patent number: 9901807
    Abstract: A shock-absorbing bushing is provided for a skateboard and includes a first layer and a second layer. The first layer has first value of hardness. The first layer is provided with a through hole. The second layer has a second value of hardness. The second layer is coupled to an outside surface of the first layer. The first layer and the second layer are formed of plastic materials coupled together as a unitary body and exhibiting at least two different values of hardness, such as being flexible in the interior and stiff in the exterior, or being stiff in the exterior and flexible in the interior. The skateboard shock-absorbing bushing is mountable to the skateboard by for example being coupled to an axle of a retainer seat to which a roller support frame is mounted.

  • Patent number: 8827285
    Abstract: A wheel axle fixing structure of a skateboard is provided for overcoming the drawbacks of a conventional coupling structure between a mounting bracket and a wheel axle of a skateboard and includes a mounting bracket, a wheel axle, and a fixing collar. The mounting bracket has an axle receiving hole that includes two internal threading sections having threads of opposite directions (such as forward thread and backward thread). The wheel axle has an axle external threading section and is fit to the fixing collar that has a collar external threading section. The axle external threading section and a collar external threading section are respectively screwed to the two internal threading sections having threads of opposite directions. The opposite directions of the threads at the two threaded sections provides tightening effects in opposite direction so that one threaded section getting loosened help more securely tighten the other threaded section.

  • Patent number: 8757647
    Abstract: A skateboard includes a support bracket mounted to an underside of the skateboard, a retention ring, and a wheel axle to which wheels are mounted. The support bracket has an axle hole that includes an internally threaded section and a groove. The retention ring is capable of elastic deformation. The wheel axle has an end that includes an externally threaded section and a retention slot. Through the threading engagement between the internally threaded section and the externally threaded section, the end of the wheel axle is fastened in the axle hole. With the retention ring retained between the groove and the retention slot by having a portion of the ring received in the groove and another portion received in the retention slot, the end of the wheel axle is retained in the axle hole without axial movement.
