Abstract

Device for driving in snow. The invention relates to a device making it possible to drive over snow without becoming embedded (sinking) in it or sliding on it. It consists of a roundel (1) clipped on a component (2), itself fixed to the wheel rim (4). This method is repeated several times on this same wheel rim (4). This device may, for greater secureness, be connected via a clip (3). Applicable to the field of the cycle and monocycle.

Description

La présente invention a pour objet une roue avec des rondelles sur sa circonférence pour faciliter le déplacement sur terrain mou, tout particulièrement sur la neige. The present invention relates to a wheel with washers on its circumference to facilitate movement on soft ground, especially on snow.

Comme on le sait, les roues ont leur circonférence munie d'un pneu à crampons ou lisse, plat, rond, triangulaire qui porte sur le sol et ce genre de pneu n'est pas approprié pour la neige. Le dispositif selon l'invention permet de remédier à cet inconvénient et supprime tous ces genres de pneumatique,. pour disposer les unes derrière les autres sur la circonférence de la jante (4) des rondelles (i) qui, en leur axe (5) sont clipsées sur une pièce (2) qui, elle-même, est fixée à une jante (4). Ces rondelles sont à peu près celles du type que l'on utilise sur les bâtons de ski, ce qui expli que la portae sur la neige bt mais leurs dimensions peuvent changer suivant le poids du véhicule. As is known, the wheels have their circumference provided with a studded or smooth, flat, round, triangular tire which bears on the ground and this kind of tire is not suitable for snow. The device according to the invention overcomes this drawback and eliminates all these types of tire. to arrange one behind the other on the circumference of the rim (4) of the washers (i) which, in their axis (5) are clipped on a part (2) which, itself, is fixed to a rim (4 ). These washers are almost those of the type used on ski poles, which explains that the portae on snow bt but their dimensions can change depending on the weight of the vehicle.

La figure 1 représente en coupe de côté le dispositif selon l'invention. La figure 2 représente la coupe de face ou de dos, variante de ce dispositif. Figure 1 shows in side section the device according to the invention. Figure 2 shows the front or back section, variant of this device.

Les rondelles (1) figure 3 fixées les unes derrière les autres sur la jante (4) figure1 d'une roue de bicyclette ou mobylette ou moto permettent à celles-ci de ne pas s'enfoncer dans la neige comme un pneu neige ou autre. Leur fixation figure 5 à la jante (4) est faite par l'intermédiaire d'une pièce (2) qui est fixée dans la feuillure de la jante (4), et sur cette pièce est clipsée la rondelle. The washers (1) in figure 3 fixed one behind the other on the rim (4) in figure 1 of a bicycle or moped or motorbike wheel allow these not to sink into the snow like a snow tire or the like. . Their fixing in FIG. 5 to the rim (4) is made by means of a part (2) which is fixed in the rebate of the rim (4), and on this part is clipped the washer.

Ces memes rondelles peuvent être reliées entre elles figure;5 par une agrafe(3) qui, d'une part, évite à la rondelle (1) de se soulever et, d'autre part, permet de les rendre solidaires les unes aux autres. Cette agrafe (3) peut servir par son usinage comme clou à verglas. Le téton de la pièce (2) se clipse dans l'axe (5) de la rondelle (I) qui peut eatre munie en son centre d'une pointe en acier,ce qui fait un clou à neige ou verglas. These same washers can be connected to each other in the figure; 5 by a clip (3) which, on the one hand, prevents the washer (1) from lifting and, on the other hand, makes it possible to make them integral with one another . This clip (3) can be used by its machining as an ice nail. The stud of the part (2) is clipped on the axis (5) of the washer (I) which can be provided in its center with a steel point, which makes a snow or ice nail.

Ces rondelles peuvent être fabriquées en caoutchouc,, métal, plastique,, de géométrie différente pour permettre leur déplacement sur différents types de neige. These washers can be made of rubber, metal, plastic, of different geometry to allow their displacement on different types of snow.

L'adhérence restant toujours à 100/I00 entre la rondelle (i) figure 4 et le sol suite à la fixation en son centre d'un axe pivotant a pour effet de suivre l'inclinaison (6) de la pente tout en gardant la jante (4) verticale. Bien entendu la jante (4) peut être de forme différente, mais le principe est de disposer figure 1, figure 2 ces rondelles ou plaquettes de formes géométriques diverses ce qui reste l'originalité de cette invention. The adhesion still remaining at 100/100 between the washer (i) in Figure 4 and the ground following the fixing in its center of a pivoting axis has the effect of following the inclination (6) of the slope while keeping the vertical rim (4). Of course the rim (4) can be of different shape, but the principle is to have figure 1, figure 2 these washers or pads of various geometric shapes which remains the originality of this invention.

Grâce à la géométrie des rondelles (1) et de leur espace entre elles figure 2, dans toutes les inclinaisons de la jante, les rondelles (1) ne peuvent se toucher entre elles et gardent ainsi toute leur efficacité d'adhérence et de mouvement. Le principe ne ressemble en rien aux chenilles qui, elles, sont faites de plaquettes reliées les unes aux autres. Le déplacement sur la neige est fait par l'intermédiaire de plusieurs roues de façon qu'unie grande surface d'adhérence soit sur le sol. Placez une chenille sur une jante (4) et il n'est plus possible d'avancer sans la faire glisser sur la neige. De même mon procédé ne peut remplacer une chenille car son originalité est que chaque élément figure 3 est fixé à la jante (4) pour rendre efficaces les rondelles (1) libres de leur mouvement. Thanks to the geometry of the washers (1) and their space between them Figure 2, in all the inclinations of the rim, the washers (1) cannot touch each other and thus keep all their effectiveness of adhesion and movement. The principle in no way resembles the tracks which, themselves, are made of plates connected to each other. The movement on snow is made by means of several wheels so that a large grip surface is on the ground. Place a track on a rim (4) and it is no longer possible to move forward without sliding it over the snow. Similarly, my process cannot replace a track because its originality is that each element in Figure 3 is fixed to the rim (4) to make the washers (1) free to move freely.

Dipositif caractérisé en ce que la jante (4) est usinée ou moulée de manière à ce que la cale ou pièce (2) fasse partie intégrante de la jante. Device characterized in that the rim (4) is machined or molded so that the shim or piece (2) is an integral part of the rim.

Le dispositif selon l'invention est applicable dans le domaine du cycle ou motocycle et l'usinage peut être artisanal ou industriel. The device according to the invention is applicable in the field of cycle or motorcycle and the machining can be artisanal or industrial.
