Definitions

  • the footing is divided into two parts, with the second caster being engaged at one footing part, with the first caster being engaged at the other footing part, with the divided footing being connected via a torsion bar.
  • the first caster is engaged at an extended line of the torsion bar, and the second casters are symmetrically engaged about the extended line of the torsion bar.
  • the front end of the sitting plate is rotatable at the center of the footing by means of a rotating shaft and is extended toward a rear side of the footing, and a plate is formed at an outer side of the footing, and a third caster is engaged at a bottom surface of the plate.
  • the number of the casters are two, with an auxiliary wheel being engaged at a bottom surface of the footing while matching with two hypotenuses connected from the first caster to the second caster.
  • the twist board according to the present invention consists of simple geometry parts, so there are less failures, and durability is excellent.
  • the twist board according to the present invention needs a least number of parts, which results in reducing unit costs, and productivity can be enhanced.
  • the conventional S-board is designed in such a way that two casters are provided, so it is not easy for a rider to gen on a board, stepping on a footing, which consequently leads to an easier tumbling before traveling; however the twist board according to the present invention consists of three casters, which helps a rider to easily get on a board, stepping on a footing.
  • the twist board according to the present invention makes it possible to prevent the damages of a board which might occur as a footing collides with the ground when a footing is over tilted while obtaining a traveling force by tilting a footing. It is possible to prevent a rider from falling which used to happen in the conventional art due to an over tilting.
  • the board keeps moving with the aid of inertia force.
  • a rider is needed to move far in order to collect the board; however in the present invention, when a rider gets off from the board in the course of traveling, the twist board is designed to return back toward a rider with the aid of a one-side weighted balance of a footing, so a rider does not need to move far toward the board.

In this state, when the rider biases the weight in either the left direction or the right direction, a traveling force is generated as the first caster 121 and the second caster 122 are driven.
  • the rider generates a traveling force in such a way to bias the weight in one direction, and then to move the weight to the opposite side while preventing the rider from tumbling.
  • the first caster 121 and the second caster 122 are driven, thus generating a traveling force.
  • the twist board 100 is forced to move forward in a S-shape.
  • twist board 100 is designed to travel forward with one vertex of the footing 110 being positioned at its front side; however when a twist board is designed to move in the opposite direction, one side of the footing with two second casters is designed to travel forward, for which it is needed to change the wheel phases of each wheel engaged at the footing to 180 degrees.
  • two footings for the left foot and the right foot to be positioned, and two footings are connected with a torsion bar, so two footings can alternately tile in the left and right directions of the length of the torsion bar.
