FR2778888A1 - Motorized water sport board driven in upright or prone position - Google Patents

Abstract

The board can be used with the driver in either an upright or prone position. It has a body (1) with a nose (2) that is raised upwards. A support (3) is positioned perpendicular to the axis of the board, and this carries an outboard motor (4). The shaft of the motor is located through a cut out (5) that is formed in the body and extends from one end of the body as far as the support. A fuel reservoir (7) supplying the motor is fixed between the body and the support.

Description

-1 - The present invention relates to the motorization of a nautical board

  which allows its user to move on standing water

or lying.

  Traditionally, boards require the use of muscular force, the association of which with natural elements (wind, waves, currents) is essential. These natural elements are very random. Indeed windsurfing requires wind, if it is weak or too powerful, the practice of this sport is too difficult or even impossible. For surfing or body-boarding, it is the waves that are essential, if the sea is calm or raging, once again the practice is difficult or impossible. Hydro-speed also has drawbacks of this type, in fact the necessary currents change according to the seasons, the snow melts favor them, but by definition place them in a very short period and in very cold water. The device according to the invention allows to overcome these drawbacks. According to a first characteristic, it comprises a motor allowing the movement of the board on the water whatever the natural conditions, the direction being obtained by displacement of the body of the user tilting the board towards the

desired direction.

  According to particular embodiments: - The motorized board has a specific transverse profile in two angular half-faces in contact with the water facilitating the tilting from one edge to the other as well as the general stability of the board. - The front of the raised board allows the absorption of waves and

choppers.

  - An engine support fixed perpendicular to the body of the board

  used to position the outboard motor.

  - An outboard motor powerful enough to move the

board with its user.

  - A cutout at the back of the engine mount to the end

  rear of the board allows the passage of the motor shaft.

  - A tank is attached to the body of the board at the front of the engine mount. -2- - A joystick with cable and protective sheath acts as an accelerator. - A lifting beam attached directly to the engine facilitates changes

of directions.

  - An inflatable float attached to the back of the body of the board absorbs

  rear impact and compensates for the weight of the engine.

  The accompanying drawings illustrate the invention:

  - Figure 1 shows the plan view.

  - Figure 1 shows the plan view, without the engine, the accelerator,

  the lifting beam and the inflatable float.

  - Figure 3 shows the longitudinal section.

  With reference to these drawings, the device comprises the body (1) of the board, the end of which ends with the nose (2) raised from the board. The body (1) and the nose (2) are made of unsinkable and resistant materials so that the board resists the addition of

  engine and its user while floating.

  The motorization includes the engine support (3), the outboard motor (4), a rear cutout (5), an accelerator (6), a tank (7), a lifting beam (8) and an inflatable float ( 9) located at the back

of the board.

  The specific profile in two angular half-faces of the face of the board in contact with water, allows by simple displacement of the body of the user to make the invention float only on a half-face, thus the new surface of flutter offsets the propeller of the

  motor (4) and turns the board.

  The nose (2) of the board located at the front of the board must be raised enough to allow the board to stay on the water

despite waves and choppy water.

  The engine support (3) allows the engine to be positioned out of

  edge (4), it is firmly fixed perpendicularly in the axis of the body (1) of the board in order to absorb all the stresses of the motor (4). This engine support (3) is located in the axis of the board

in the 3/4 rear position approximately.

  the outboard motor (4) must be powerful enough to

  move the board with its user.

  -3- A cutout (5) located at the rear of the engine mount (3) up to the rear end of the board allows the shaft of the

  motor (4), knowing that this shaft is pivoting.

  A tank (7) located at the front and in support of the engine support (3) is fixed on the body (1) of the board, in order to supply the engine

(4) in fuel.

  The accelerator (6) must be actuated by simple pressure of the fingers on a mobile lever connected to the motor (4) by a cable, and its protective sheath, long enough to be used in both

positions.

  The inflatable float (9) is fixed to the rear end of the body (1) of the board. It is of sufficiently large diameter so that its offset at the rear can absorb rear impacts, but

  also compensate for the weight of the engine.

  A lifting beam (8) fixed directly on the motor (4) makes it possible to pivot the motor (4) thus turning the board no longer by tilting the board and offset from the body of the user but by the use of his feet lying down. In the case of using the invention without a lifting beam (7), the direction of the motor (4)

  must be locked in neutral position.

  By way of nonlimiting example, the board will have dimensions of

  around 60 cm for the width and 200 cm for the length.

  The device according to the invention is particularly intended for leisure

and nautical trips.
