  • an object of the present invention is to provide a truck for a skateboard which is formed of a plate- shaped member in a manner such that both ends of the plate- shaped member are bent to define center arms, and a shaft having wheels coupled thereto is mounted to the center arms, thereby improving shock absorption capability, increasing jumping performance, and attaining excellent direction change ability of the skateboard.
  • Another object of the present invention is to provide a truck for a skateboard in which center arms are integrally connected with each other, thereby further improving shock absorption capability and increasing jumping performance.
  • a truck for a skateboard having a shaft mounted thereto, the shaft having wheels coupled to both ends thereof, a coupling part having a through- hole projectedly formed in one side of a middle portion of the shaft, and a support part being projectedly formed on the other side of the middle portion of the shaft, wherein the truck is formed of a plate- shaped member in a manner such that both ends of the plate- shaped member are bent to face each other and define center arms, the coupling part is locked to one center arm by a connector, and the other center arm is defined with a pocket such that the support part can be inserted into the pocket with an elastomeric element coupled in the pocket.
  • free ends of the center arms are inclined downward.
  • the center arms are formed by bending such that they are integrally connected with each other.
  • the connector comprises a washer-integrated type bolt having a head part which has a rounded upper surface, is defined with a wrench groove on a center portion thereof, and is formed with a fastening protrusion on an edge thereof; a shock-absorbing rubber placed on upper and lower surfaces of the coupling part of the shaft; and a nut locked with a thread part of the washer-integrated type bolt which passes through one center arm.
  • the truck for a skateboard according to the present invention provides advantages in that it is possible to realize excellent shock absorption capability and jumping performance, and the direction of the skateboard can be easily changed. Further, by changing the material or thickness of the plate-shaped member constituting the truck, it is possible to construct a truck which is optimally suited for the weight of a rider.

  • FIG. 8 is a perspective view illustrating a truck for a skateboard in accordance with a second embodiment of the present invention.
  • skateboard 200 truck for a skateboard
  • FIG. 4 is a perspective view illustrating the use of a truck for a skateboard in accordance with a first embodiment of the present invention
  • FIG. 5 is a perspective view illustrating the truck for a skateboard in accordance with the first embodiment of the present invention.
  • the truck 200 for a skateboard in accordance with the first embodiment of the present invention is installed on the lower surface of a skateboard 100 and has a shaft 300 to which wheels 310 are coupled.
  • the wheels 310 are respectively coupled to each end of the shaft 300.
  • a coupling part 320 having a through-hole projects from one side of the middle portion of the shaft 300, and a support part 330 projects from the other side of the middle portion of the shaft 300.
  • the truck 200 to which the shaft 300 is mounted is formed of a plate-shaped member 210. Both ends of the plate-shaped member 210 are bent to face each other and define two center arms 230.
  • the coupling part 320 is locked to one center arm 230 by a connector 400, and the other center arm 230 has a pocket 232 defined therein such that the support part 330 can be inserted into the pocket 232.
  • the pocket 232 is recessed sufficiently deeply therefor.
  • an elastomeric element 234 such as a urethane packing is coupled in the pocket 232 so that the free end of the support part 330 can be placed in the elastomeric element 234.
  • the wheels 310 Due to the presence of the support part 330 inserted into the pocket 232, the wheels 310 can be reliably held in place. When a skateboard turns, since the support part 330 finely pivots in the pocket 232 within a predetermined range, turning can be easily conducted.
  • both ends of the plate-shaped member 210 are bent twice such that the free ends of the center arms 230 are inclined downward to some extent.
  • the two center arms 230 are separated from the base part of the plate-shaped member 210 which is directly locked to a board 100.
  • the angles of the center arms 230 can be variously changed as desired.
  • the coupling part 320 projectedly formed on one side of the middle portion of the shaft 300 has the through-hole, and one center arm 230 associated with the coupling part 320 has a hole 236, so that the connector 400 is passed through the through-hole and the hole 236 and locks the coupling part 320 to the center arm 230.
  • the connector 400 may comprise a conventional bolt or an elastic member such as a urethane rubber.
  • the connector 400 having the structure shown in FIGs. 6 and 7 is used.
  • the connector 400 is composed of a washer-integrated type bolt 410, a shock- absorbing rubber 420 and a nut 430.
  • the washer- integrated type bolt 410 has a head part 412 which has a rounded upper surface, and is defined with a wrench groove 414 on the center portion thereof.
  • a fastening protrusion 416 is formed on the edge of the lower surface of the head part 412.
  • the shock- absorbing rubber 420 is placed on the upper and lower surfaces of the coupling part 320 of the shaft 300 and surrounds the washer- integrated type bolt 410.
  • the nut 430 is locked to the thread part 418 of the washer-integrated type bolt 410 which passes through one center arm 230.
  • the wrench groove 414 is defined on the center portion of the head part 412 of the washer- integrated type bolt 410, it is possible to prevent the wrench groove 412 from being deformed due to friction. Also, since the fastening protrusion 416 is formed on the edge of the lower surface of the head part 412 of the washer- integrated type bolt 410, the shock-absorbing rubber 420 placed under the head part 412 can be reliably held in place.
  • FIG. 8 is a perspective view illustrating a truck for a skateboard in accordance with a second embodiment of the present invention.
  • the center arms 230 which are formed by bending both ends of a plate-shaped member 210 to face each other, are integrally connected with each other.
  • a plate-shaped reinforcing piece 250 is placed under the center arm 230, such that it is possible for the truck 200 to sustain an increased load.
  • both ends of the plate-shaped member 210 having a springing characteristic are bent to define the center arms 230, and the shaft 300 having wheels coupled thereto is mounted to the center arms 230, whereby the shock absorption capability is improved and the jumping performance of the skateboard increases.
  • the truck 200 is formed of the plate- shaped material having substantially the same elasticity as a leaf spring, and shocks are transmitted to the shaft 300 via wheels 310 which are brought into contact with the ground and roll thereon. Shocks transferred to the shaft 300 are effectively dispersed by the center arms 230, so that the shocks can be reliably mitigated.
  • a shaft having wheels coupled thereto is mounted to center arms which are formed by bending a plate-shaped member, so that shock absorption capability is improved, and the jumping performance of the skateboard increases.
  • the structure of the truck according to the present invention can be applied not only to a skateboard but also to various vehicles having wheels, thus contributing to the leisure industry.

Abstract

La présente invention concerne un bloc-essieu pour une planche à roulettes qui comporte un essieu monté sur celui-ci. L’essieu possède des roues couplées à ses deux extrémités. Une partie de couplage qui possède un trou débouchant est formée de façon saillante dans un côté d’une partie médiane de l’essieu, et une partie de support est formée de façon saillante sur l’autre côté de la partie médiane de l’essieu. Le bloc-essieu est formé d’un élément en forme de plaque de manière telle que les deux extrémités de l’élément en forme de plaque soient pliées pour se faire face et définir des bras centraux. La partie de couplage est verrouillée sur un bras central par un connecteur, et l’autre bras central comporte une poche définie dans celui-ci de sorte que la partie de support puisse être insérée dans la poche avec un élément élastomère couplé dans la poche.
