Abstract

The sail or gravity powered cart has a front fork (1) with a wheel (2) welded to a tube (4) which is curved (5) and threaded at its rear end (6). The fork is threaded to a sleeve (7) threaded on its interior (8) forming the rear axle base. A board (10) which is curved at the rear rests on the rear axle on a bracket (12) and is mounted at the junction between the fork and tube.

Description

La présente invention concerne un engin tout terrain pour se faire tracter debout par un cerf volant sur la plage et descendre des pentes en herbe terre ou en asphalte. The present invention relates to an all-terrain vehicle for being towed upright by a kite on the beach and descending slopes on grass or asphalt.

L'engin se compose d'une fourche avant de vélo équipée d'une roue. La fourche de vélo est soudée à un tube central en acier creux courbé à l'arrière. extrémité arrière du tube central est filetée et pleine dans la partie filetée. La partie filetée est vissée à un manchon fileté à l'intérieur, en forme de T. Le manchon compose la base de l'axe arrière. The machine consists of a bicycle front fork fitted with a wheel. The bicycle fork is welded to a central hollow steel tube curved at the rear. rear end of the central tube is threaded and solid in the threaded part. The threaded part is screwed to a threaded sleeve inside, T-shaped. The sleeve makes up the base of the rear axle.

Les parties extrêmes du manchon sont munies de deux tubes en alliage, chacun soudé ou vissé. Les deux tubes en alliage léger et solide sont munis à leurs bouts d'une tige en acier, soudée, d'un diamètre inférieur. les tiges viennent s'encastrer deux roues. The end parts of the sleeve are provided with two alloy tubes, each welded or screwed. The two light and solid alloy tubes are provided at their ends with a welded steel rod of a smaller diameter. the rods come to fit two wheels.

Une planche courbée à l'arrière est fixée à une plaque rectangulaire plate en acier. La plaque est soudée à la jonction du tube central et de fourche. L'arrière de la planche repose sur une gangue en plastique. La gangue couvre une grande partie de l'axe arrière de l'engin. Cette gangue en plastique épouse la forme de l'arrière de la planche et permet de stabiliser la planche. A curved plank at the back is attached to a flat rectangular steel plate. The plate is welded at the junction of the central tube and fork. The back of the board rests on a plastic gangue. The gangue covers a large part of the rear axis of the machine. This plastic gangue follows the shape of the back of the board and helps stabilize the board.

Lors de l'inclinaison de la planche à droite ou à gauche, le bout fileté du tube courbe vissé au manchon de l'axe arrière effectue une rotation permettant à l'engin de virer avec une incidence importante. L'axe arrière se déplace dans le sens inverse de la roue avant, qui permet à l'engin d'effectuer un virage serré. Les cotés de la partie courbe de la planche viennent buter sur la gangue en plastique, ce qui a pour effet de limiter l'inclinaison. When tilting the board to the right or to the left, the threaded end of the curved tube screwed to the sleeve of the rear axle performs a rotation allowing the machine to turn with a significant incidence. The rear axle moves in the opposite direction to the front wheel, which allows the machine to make a tight turn. The sides of the curved part of the board come up against the plastic gangue, which has the effect of limiting the inclination.

Selon des modes particuliers de réalisation - Le manchon de l'axe arrière peut être relié au tube central courbe par une bande plastique auto-fusionante. According to particular embodiments - The sleeve of the rear axle can be connected to the curved central tube by a self-fusing plastic strip.

- l'axe arrière peut être rattaché à la planche par des bandes renforcées de tissus élastiques passant autour de la gangue et fixé sous l'arrière de la planche. - the rear axle can be attached to the board by bands reinforced with elastic fabrics passing around the gangue and fixed under the back of the board.

- l'engin peut-être constitué de quatre roues avec un tube central en alliage léger et solide, courbé à chacun de ses bouts sur une longueur de 5 à 7 cm avec un angle de 20 à 60 degrés. Les extrémités filetées et pleines sont vissées dans deux manchons filetés à l'intérieur. L'axe arrière et avant est fabriqué sur le meure modèle que le tricycle. La planche fixée à une plaque rectangulaire soudée au milieu du tube. - the machine can be made up of four wheels with a central tube in light and solid alloy, curved at each of its ends over a length of 5 to 7 cm with an angle of 20 to 60 degrees. The threaded and solid ends are screwed into two threaded sleeves inside. The rear and front axle is made on the same model as the tricycle. The board fixed to a rectangular plate welded in the middle of the tube.
