Definitions

  • the present invention relates to skateboard trucks, and more particularly, hangers for a skateboard truck.
  • a skateboard truck is the component, which lies between the skateboard wheels and bearings on the one hand and the skateboard on the other hand.
  • the skateboard is the platform whereby the person user or skateboard rider is carried and supported.
  • skateboard trucks are generally constructed from five (5) distinct and separate components being the axle, the hanger, the baseplate, the bushes and the central bolt.
  • the bushes and the central bolt when combined in use ' in the hanger, is known in the art as the "kingpin".
  • skateboard trucks utilise a two-piece hanger/axle assembly.
  • this involves the use of two types of material such as a steel material axle, which is cast or cold pressed into another metal alloy hanger to create a two-piece hanger unit.
  • a hanger for a skateboard truck including: a body, an axle integrally formed with the body, wherein in use, the axle is prevented from disengaging the body.
  • the axle includes a first member and a second member, the first member and second member being spaced apart.
  • first member and the second member each have a threaded portion adapted to retain a wheel.
  • the axle and the body are uniformly constructed from a titanium based material.
  • the titanium based material is in the range of about 50% -100% by weight titanium. It is further preferred that the titanium based material includes a titanium based composite of about 90% titanium.

  • the first member 4 and the second member 12 both function to each hold and retain a spinning wheel (not show in the drawings) for a skateboard as a whole.
  • the axle which is constituted by the combination of the first member 4 and the second member 12, does not spin or rotate within the hanger 2.
  • the first member 4 is provided with a threaded portion 6 at its end which is adapted to receive or retain a first spinning wheel usually a ball bearing type (which is not shown in the drawings).
  • the second member 12 is also provided with a threaded portion 14 at its end which is adapted to receive or retain a second spinning wheel usually a bait bearing type (which is not shown in the drawings).
