Definitions
- the present invention relates to a device for orienting a steering wheel of a skateboard.
- the change of direction of a skateboard is generally obtained by a system called “truck” which is found on the "skate board".
- This system has a limited turning radius, and does not allow instant stopping. Thus it can only be used on suitable surfaces.
- the device according to the invention makes it possible to remedy these drawbacks and therefore to roll on any terrain.
- a first characteristic it in fact comprises a pendulum, consisting of a weight at the end of a bar. 10
- the balance wheel is connected to the axle of the steering wheel.
- the fork of the steering wheel is perpendicular to the balance. This fork pivots by means of a rolling bearing. balls.
- the ball bearing is connected by an arm fixed to the front of the board.
- the weight of the pendulum rests and moves on a rigid convex surface, called the cradle.
- the cradle is fixed in line with the board.
- the direction of the wheel is obtained by tilting the board.
- By exerting a pressure on the right of the board the weight moves on the right of the cradle.
- the balance exerts a leverage on the axis of the steering wheel, which rotates to the right.
- the opposite phenomenon turns the wheel to the left. 20
- the cradle being convex, when the board returns to the horizontal, the weight of the pendulum returns to the center of the cradle, hence the name "pendulum direction".
- the device comprises a weight (1) pierced in its center, a bar (2) and a fork (3).
- the device (1, 2,3) represents the pendulum.
- the balance is connected to the axis (4) of the steering wheel (9) by the fork (3).
- the fork (5) of the steering wheel (.9) is perpendicular to this balance.
- This fork (5) pivots by means of a ball bearing (7).
- the ball bearing (7) is connected to an arm (5) fixed to the front of the board (6).
- the weight (1) of the pendulum (1,2,3) rests and moves on a rigid convex surface (10) called cradle.
- the cradle is fixed in the extension of the board (6) by two symmetrical arms (11).
- the direction of the wheel (9) is obtained by tilting the board.
- the sportsman exerts a pressure on the right of the board, the weight (1) moves on the right of the cradle (11).
- the balance exerts a lever force in the axis (4) of the wheel (9) which rotates on the right. If the board (6) is returned to the horizontal, the weight (1) returns to the bottom of the cradle, 40 thus the board (6) resumes a straight direction. If the athlete exerts pressure on the left of the board, the weight (1) moves to the left of the cradle.
- the board will have a length between wheel axles of 1.30 m and a width of 0.25 m.
- the device according to the invention is intended to orient a steering wheel without the arms of the user.
