Abstract

The device enables the swinging of the board when going round a curve combining inclination and steering. The device is fitted to a board with two front wheels and one rear wheel. The front axle comprises a parallelogram which deforms under the action of the user standing on the platform (11). The parallelogram comprises a steering crosspiece (2), a swinging arm (8) and two clevises (7) on which the wheels (6) are connected.

Description

DESCRIPTION
La présente invention consiste en un dispositif de pendulation spécifique au domaine des planches à roulettes, désignées couramment skate-board ou long-board en utilisation sur sol dur, et les planches à bandages pneumatiques en ce qui concerne l'utilisation tout-terrain de type speed-sail . Le domaine étudié est donc celui des sports de glisse, et de l'industrie du cycle en particulier.
DESCRIPTION
The present invention consists of a tilting device specific to the field of skateboards, commonly known as skateboards or longboards for use on hard ground, and pneumatic tire boards with regard to all-terrain use of the type speed-sail. The field studied is therefore that of sliding sports, and of the cycle industry in particular.

L'invention permet d'évoluer à l'aide du free-board pendulaire en adoptant une posture corporelle dont l'axe est conjugué à celui de la pendulation du dispositif, en induisant un contrôle proprioceptif par l'utilisateur du mme type que sur un surf évoluant sur l'eau ou sur la neige. The invention makes it possible to evolve using the pendulum freeboard by adopting a body posture whose axis is conjugated with that of the pendulum of the device, by inducing proprioceptive control by the user of the same type as on a surfing on water or on snow.

Le free-board pendulaire est utilisable en tant que tel, sans adjonction d'un autre dispositf, dans le cas de l'évolution par l'énergie musculaire de son utilisateur ( trottinement), dans le cas du dévallement d'une pente, et dans le cas ou celui-ci est relié par un lien quelconque entraîné par un dispositif fixe ou mobile. The pendulum freeboard can be used as such, without the addition of another device, in the case of evolution by the muscular energy of its user (jumping), in the case of the downhill of a slope, and in the case where it is connected by any link driven by a fixed or mobile device.

L'invention est applicable à d'autres sources d'éner- gie, éolienne, thermique, électrique, par l'adjonction d'un gréement, ou par le montage d'un groupe moto-propulseur. The invention is applicable to other sources of energy, wind, thermal, electric, by the addition of a rigging, or by the mounting of a powerplant.

Pour l'ensemble des applications du dispositif, les carac téristiques de la liaison au sol-lacet et roulis-augmentent considérablement la tenue de route, par rapport aux planches existantes, notamment en virage et en dévers.For all of the device's applications, the characteristics of the ground-yaw and roll-link considerably increase the road holding, compared to the existing boards, in particular in turns and on slopes.

L'effet induit de cette liaison au sol performante est également l'accès à des vitesses d'évolution plus élevées. The induced effect of this efficient ground connection is also access to higher speeds of evolution.

En l'état actuel de la technique des planches à roulettes, la géométrie des trains roulants sont tous à essieux rigides, aucune invention connue ne revendique un quelconque dispositif de pendulation des roues en elles-mmes.In the current state of the art of skateboards, the geometry of the running gear are all rigid axles, no known invention claims any device for tilting the wheels themselves.

Le dispositif selon l'invention est une structure déformable en forme de double parallélogramme équipée d'une laison souple à 3 degrés de liberté, reliant la planche du free-board et les axes des 2 roues avant. (FIG. 1)
Le principe structurel de l'invention est le suivant : (FIG. 2) chacune des 2 roues du train-avant (6G), (6D), est reliée au parallélogramme déformable par une chappe (7) assurant la fonction de palier-butée.
The device according to the invention is a deformable structure in the form of a double parallelogram equipped with a flexible layer with 3 degrees of freedom, connecting the freeboard board and the axes of the 2 front wheels. (FIG. 1)
The structural principle of the invention is as follows: (FIG. 2) each of the 2 front axle wheels (6G), (6D), is connected to the deformable parallelogram by a clevis (7) ensuring the function of thrust bearing .

La liaison entre chacune des 2 chappes et le parallégro- gramme déformable s'effectue par 4 pivots (5).The connection between each of the 2 caps and the deformable parallelogram is made by 4 pivots (5).

Les 2 pivots supérieurs sont reliés entre-eux par la traverse de direction (2). Les 2 pivots inférieurs sont reliés entre-eux par le bras de pendulation (8).The 2 upper pivots are interconnected by the crossbar (2). The 2 lower pivots are interconnected by the pendulum arm (8).

La traverse de direction (2) et le bras de pendulation
(8) sont tous deux équipés en leur mileu d'une laison-rotule élastique (3), (4), à débattement limité dans les plans frontaux et longitudinaux.
The steering cross member (2) and the pendulum arm
(8) are both fitted in their center with an elastic ball joint (3), (4), with limited clearance in the front and longitudinal planes.

Ces 2 liaisons-rotules élastiques sont reliées entreelles par la colonne de direction (10), assurant la fonction de levier de commande du parallélogramme déformable. These 2 elastic ball joints are connected to each other by the steering column (10), ensuring the function of the control lever of the deformable parallelogram.

Cette colonne de direction (10) est fixée perpendiculairement dans le plan frontal au plateau de guidage (11), sur lequel l'utilisateur est installé. This steering column (10) is fixed perpendicularly in the frontal plane to the guide plate (11), on which the user is installed.

Dans le plan longitudinal, la colonne de direction est inclinée vers l'avant de l'engin selon un angle de chasse alpha. In the longitudinal plane, the steering column is tilted towards the front of the machine at an alpha hunting angle.

Le principe fonctionnel selon l'invention est le suivant : (FIG. 2) lorsque l'utilisateur place son centre de gravité corporel-statique ou dynamique-dans le plan de la colonne de direction, le parallélogramme ne subit pas de déformation, les roues sont perpendiculaires au sol, et l'essieu avant est orienté dans l'axe longitudinal de 1'engin. The functional principle according to the invention is as follows: (FIG. 2) when the user places his body center of gravity-static or dynamic-in the plane of the steering column, the parallelogram does not undergo deformation, the wheels are perpendicular to the ground, and the front axle is oriented in the longitudinal axis of the machine.

(FIG. 3) lorsque l'utilisateur déplace son centre de gravité corporel-statique ou dynamique-en dehors du plan de la colonne de direction, le parallélogramme se déforme sous l'effet de levier de la colonne de direction, les roues s'inclinent par rapport au sol, et l'essieu avant s'orien- te selon un angle de braquage beta, ce qui permet d'engager le virage contrôlé par l'utilisateur.   (FIG. 3) when the user moves his body center of gravity-static or dynamic-outside the plane of the steering column, the parallelogram is deformed under the leverage of the steering column, the wheels tilt to the ground, and the front axle steers at a beta steering angle, allowing you to initiate the user-controlled turn.
