Definitions

  • the present invention relates to a suspension truck for roller skates or skateboards.
  • Roller skates include a frame, truck and rollers that attach to the sole of a shoe, and skateboards include a deck, truck, and rollers.
  • the truck is the part that connects the frame or deck and the rollers.
  • the truck is a form in which a hanger is connected to a base plate with a kingpin, and is actually a skeleton that supports a skateboard or a shoe. A total of two are installed, one at the front and back of the frame or deck.
  • Maintaining balance is of great interest to roller skaters and skateboarders, and maintaining such balance is difficult for professional skaters or boarders who need to jump, change direction, and turn.
  • a device that assists in maintaining this balance is a truck.
  • the truck is disclosed in Korean Utility Model Publication No. 20-1993-0013190.
  • an elastic ball is interposed between the wheel hub and the substrate to assist in maintaining the balance, and serves to alleviate the impact transmitted through the roller.
  • the disclosed truck since the disclosed truck has a structure that mitigates the impact in the vertical direction, it always receives the load of the skater or boarder during skating and buffers the road impact in the gravity direction transmitted through the roller, so it is provided in the truck There is a problem that the force in the direction of gravity is concentrated on the elastic ball, so that the elasticity of the elastic ball is easily lowered in a short period of time.
  • the present invention has a problem in solving the above problems.
  • the present invention can solve the above problem by dispersing the load of skaters or boarders transmitted to the truck and the road impact force transmitted through rollers into a horizontal component and a vertical component to provide a suspension unit that cushions the horizontal component.
  • the present invention is preferable from the viewpoint of reducing the number of parts and reducing maintenance costs compared to the prior art if one suspension unit is provided for two rollers provided in the truck.
  • the present invention provides a buffer for the horizontal component by dispersing the load and the road impact force of the skater or the boarder transmitted in the vertical direction into the vertical component and the horizontal component by means of solving the problem as described above, thereby having a smaller elasticity than the prior art. Since the suspension part can be implemented by the spring, the manufacturing cost can be reduced and it can be possible to use the spring without aging of elasticity for a long time than in the prior art.
