Abstract

The scooter is composed of a chassis (3) with a platform (1) and an arm (2) supporting the handlebars (4) and the brake handle. There are four independent wheels with automatic braking when scooter is dropped

Description

La présente invention concerne un engin de descente à roues utilisable par des enfants de 10 ans au moins et par les adultes sur des pentes et pistes aménagées ou non, sur toute surface et en toute saison.The present invention relates to a descent device with wheels usable by children at least 10 years old and by adults on slopes and pistes, whether or not equipped, on any surface and in any season.

La pratique consiste à descendre des pentes en empruntant des trajectoires courbes ou droites, en maîtrisant la vitesse de descente par un système de freinage ainsi que l'évolution de l'engin après une chute et perte de contrôle par blocage des roues lors du rappel du manche en position basse.The practice consists in descending slopes by taking curved or straight paths, controlling the speed of descent by a braking system as well as the evolution of the machine after a fall and loss of control by locking the wheels when recalling the handle in low position.

D'un poids réduit, il est transportable en haut des pentes et pistes en utilisant les divers amenagements, des véhicules ou à dos d'homme.With a reduced weight, it can be transported at the top of slopes and tracks using various layouts, vehicles or on a man's back.

Un dispositif à commande manuelle permet d'accrocher I'engin à un remonte pente par verrouillage et déverrouillage de la perche. L'engin peut aussi être motorisé mécaniquement ou électriquement.A manually controlled device allows the machine to be hooked to a ski lift by locking and unlocking the pole. The machine can also be mechanically or electrically powered.

II existe deux modèles d'engin de descente. Le premier sur lequel l'utilisateur est debout sur la plate forme. Pour tourner, I'utilisateur doit prendre appui du côté choisi en se maintenant au guidon. There are two models of downhill gear. The first on which the user is standing on the platform. To turn, the user must lean on the chosen side while holding onto the handlebars.

Le deuxième reprend tous les éléments du premier sur lequel est rajouté un siège permettant à l'utilisateur d'adopter une position assis debout . Pour tourner, l'utilisateur doit prendre également appui du côté choisi en se maintenant au guidon.The second includes all the elements of the first on which is added a seat allowing the user to adopt a seated position. To turn, the user must also take support on the chosen side while holding onto the handlebars.

L'engin comprend suivant une première caractéristique, comme le montre le dessin en annexe un châssis en mécano soudé(3) ou matériaux composite, une plate-forme (1), un système de direction situé sur les roues avant et arrière, un manche (2) terminé par un guidon (4).According to a first characteristic, the machine comprises, as shown in the attached drawing, a mechanically welded chassis (3) or composite materials, a platform (1), a steering system located on the front and rear wheels, a handle. (2) terminated by a handlebar (4).

Chaque directions est composée par un axe carré limité en rotation par un carré de caoutchouc ou élastomère lui même logé dans un carré creux solidaire de l'âme centrale (3). Le système de direction peut indifféremment reprendre les systèmes existants des patins à roulettes, planches à roulettes et autres.Each direction is composed by a square axis limited in rotation by a square of rubber or elastomer itself housed in a hollow square secured to the central core (3). The steering system can indifferently take over the existing systems of roller skates, skateboards and others.

Le manche qui ne possède qu'un seul degré de liberté d'avant en arrière est considéré comme le stabilisateur de l'utilisateur. Le manche est également une commande de blocage des freins en cas de perte de contrôle. Le manche est rappelé en position basse si il est lâché et agit sur les frein.The handle which has only one degree of freedom from front to back is considered to be the user's stabilizer. The handle is also a brake lock command in the event of loss of control. The handle is recalled to the low position if it is released and acts on the brakes.

En fonctionnement normal, une poignée de frein type vélo tout terrain actionne par l'intermédiaire d'un câble et d'une tige centrale coulissante un autre câble en V relié aux freins et équilibrant ainsi le freinage. Ces freins peuvent être remplacés par des freins de type freins à tambours, à disques, ou à sangles.In normal operation, a brake handle type mountain bike activates via a cable and a central sliding rod another V cable connected to the brakes and thus balancing the braking. These brakes can be replaced by brakes of the drum, disc or strap brakes type.

La plate forme arrière est réalisée en matériaux composites mais peut être réalisée aussi en bois ou autres matériaux plastiques. Le cache avant a pour but de protéger l'utilisateur et les autres contre les projections et les chocs éventuels.The rear platform is made of composite materials but can also be made of wood or other plastic materials. The aim of the front cover is to protect the user and others against projections and possible shocks.

II sert également d'enjoliveur. It also serves as a hubcap.

L'engin de descente à roues, objet de l'invention permet à l'utilisateur d'atteindre des vitesses de l'ordre de 40 à 60 kmth avec une maniabilité accrue, une garde au sol adaptée aux terrains les plus accidentés, et un système de freinage permettant l'arrêt ou le blocage des roues en cas de perte de contrôle. Outre l'effet de pente, pour avancer l'engin peut également bénéficier d'une propulsion électrique ou thermique.The descent device with wheels, object of the invention allows the user to reach speeds of the order of 40 to 60 kmth with increased maneuverability, ground clearance suitable for the most uneven terrain, and a braking system allowing the wheels to stop or lock in the event of loss of control. In addition to the slope effect, to advance the machine can also benefit from electric or thermal propulsion.

La présente invention est destinée à être acquise par des particuliers, des collectivités publiques ou privées et de ce fait à être produite en série. The present invention is intended to be acquired by individuals, public or private communities and therefore to be produced in series.
