  • Background Art
  • Skateboards conventionally, include an elongated plate with two sets of wheels located at front and rear portions thereof. Skateboard riders propel their skateboards in a desired direction by assuming a pushing stance to thrust against the ground with one foot with the other foot positioned on the board.
  • the conventional skateboards experience various disadvantages as follows.
  • the conventional skateboards are inconvenient in use because a rider has to frequently detach one foot from the board in a pushing stance to thrust against the ground to achieve a desired propulsive force. Further, it is difficult to keep a constant speed as well as adjust the speed to exactly meet the rider's needs.
  • the conventional skateboards are designed to achieve a braking thereof using a frictional force incurred by the rider's one foot in contact with the ground. This makes it difficult for a rider to balance on the other foot positioned on the board, resulting in an unsafe or unstable riding condition.

  • each of the forward-directional casters may include a roller support attached at the lower surface of the plate and having a wedge shape that interior angles formed by respective sides thereof and the plate are acute, a roller arm coupled at an upper end thereof to the roller support and at a lower end thereof to a roller shaft, a bearing inte ⁇ osed between the roller support and the roller arm, and a roller inserted on the roller shaft, whereby the roller arm may be rotatable relative to the roller shaft about the bearing as a rotating shaft.

  • the wing portions 30a and 30b have respective brake units 31. Each of the brake units 31 is operable when a rider presses it with the heel.
  • the wing portions 30a and 30b further have respective forward-directional casters 20a and 20b spaced apart from the brake units 31 so as not to interfere pivotal rotation of the brake units 31.
  • the plate 40 may be formed of a general board, or may be substituted by aluminum pipes or other material pipes. In the latter case, the plate 40 simply serves as a shaft that connects the forward-directional casters 10 and 10a and the wing portions 30a and 30b with one another.
  • the one or more forward-directional casters 10 and 10a are aligned in a straight line on the front and rear portions of the plate 40, the brake units 31 are located at rear ends of the wing portions 30a and 30b that protrude laterally from the plate 40, and the forward- directional casters 20a and 20b are algined in a straight line on the wing portions 30a and 30b while being spaced apart from the brake units 31. All of the forward-directional casters 10, 10a, 20a and 20b are attached to four distal ends of the lower surface of the cross-shaped plate 40, thereby serving to propel the skateboard.
  • the wing portions 30a and 30b of the plate 40 are used as footholds and are pe ⁇ endicular to the front and rear portions of the plate 40 extending in a direction of travel, thereby allowing the skateboard to have a cross shape similar to the shape of an ai ⁇ lane.
  • the brake units 31 are attached to the lower surfaces of the wing portions 30a and 30b so that a pivotal rotation of their brakes 31a and 31b (shown in FIGS. 8a and 8b) is not interfered by movements of the forward-directional casters 20a and 20b.
  • the forward-directional casters 20a and 20b attached to the lower surfaces of the wing portions 30a and 30b, are adjustable in height from the ground via a size variation thereof.
  • the forward-directional casters 20a and 20b on the wing portions 30a and 30b of the plate 40 have the same size and height as those of the forward-directional casters 10 and 10a on the front and rear portions of the plate 40 such that all of the casters 10, 10a, 20a and 20b simultaneously come into contact with the ground under an assumption that the ground is flat.
  • the forward-directional casters 20a and 20b of the wing portions 30a and 30b have a size smaller than that of the other casters 10 and 10a and so that they are positioned higher than the casters 10 and 10a.
  • the casters 20 and 20a of the wing portions 30a and 30b are spaced apart from the ground.
  • the forward-directional casters 20a and 20b of the wing portions 30a and 30b spaced apart from the ground allows a rider to more easily lean the skateboard laterally. This consequently allows a rider to easily turn his/her body to the right and left to gain a desired propulsive force while balancing on the other forward-directional casters 10 and 10a attached to the front and rear portions of the lower surface of the plate 40.
  • springs may be mounted to the casters 20a and 20b.
  • the forward-directional casters 10, 10a, 20a and 20b have the same structure and function as one another, and thus hereinafter, only one of the casters, for example, the caster 10, will be explained for the clarity of description.

  • the roller arm 13 is connected to a roller shaft 14 at an opposite side of the bearing 12.
  • a roller 15 is inserted on the roller shaft 14 to rotate about the roller shaft 14.

  • the reason why the roller supports 11, in contact with the wing portions 30a and 30b and the front and rear portions of the plate 40, are formed to have an acute wedge shape is to enable a free angular horizontal rotation of the forward-directional casters 10, 10a, 20a and 20b about the bearings 12, thereby achieving an increased propulsive force as compared to a conventional vertical roller support.
  • the brake unit 31 is mounted at the wing portion 30a and serves to stop the operation of an associated one of the forward- directional casters, i.e. the forward-directional caster 20a, and to rotate the skateboard thereabout.
  • the brake unit 31 may be mounted at a front end of the wing portion 30a rather than the rear end thereof as shown in FIG. 6c. In this case, a rider can brake the skateboard by pressing the brake 31a with the toes rather than the heel.
  • FIG. 7 is a cross-sectional view of the brake unit 31.
  • the brake unit 31 includes a pair of outer pipes 38 fitted in grooves of the wing portion 30a, an inner pipe 39 inserted in the outer pipes 38 to freely rotate via a plurality of balls 37, and holder springs 35 each affixed at its one end to the inner pipe 39 and at the other end to the outer pipes 38 by passing through holding holes 36 formed through the inner pipe 39 and the outer pipes 38 at predetermined positions.

  • the inner pipe 39 synchronically rotates to cause a torsional deformation of the holder springs 35 affixed to the inner circumferences of the inner pipe 39 and the outer pipes 38.
  • the holding holes 36 allow the holder springs 35 to generate a torsion restoration force of the inner pipe 39 to cause the inner pipe 39 to return to its original state. In this manner, the brake 31a is returned to its original position.
  • FIGS. 8a and 8b are bottom views illustrating the propulsive operational states of the ai ⁇ lane-shaped skateboard of FIG. 1.

Cette planche à roulettes comprend une plaque en forme de croix dotée d'une paire d'ailettes intégrales disposées sur les côtés latéraux opposés en tant que points d'ancrage pour soutenir les deux pieds d'un utilisateur, une pluralité de chasses à direction avant fixées aux quatre extrémités distales d'une surface inférieure de la plaque pour propulser la planche à roulettes dans un sens de trajet voulu, et une ou plusieurs unités de frein disposées par rotation au niveau des extrémités arrière des ailettes de la plaque pour entrer en contact avec le sol lors de la réception d'une force de pression externe afin de générer une force de freinage. Dans une alternative, la plaque présente une forme allongée et une paire d'ailettes sont reliées séparément à la plaque. Cette planche à roulettes en forme d'avion fonctionne simplement lorsque l'utilisateur fait pivoter son corps à droite et à gauche, et présente une réduction de vitesse ou un freinage facile et rapide.
