Abstract

PRÉCIS Durant l'utilisation d'une bicyclette en hiver on se trouve confronté à un problème de glissement du pneu de la roue motrice. Dans la présente invention le pneu de la roue motrice est remplacer par une chenille.ACCURATE During the use of a bicycle in winter there is a problem of slippage of the tire of the drive wheel. In the present invention, the tire of the driving wheel is replaced by a track.

Description

~ ette chenille permet au cycllste d~utlllser toute sa torce molnce sans qu 1l y alt ~e pene a aanerence avec le terrain. La chenille comporte une roue libre à sa suite afin d'augmenter sa surface portante au sol.
DESCRIPTION GÉNÉRAL 21141~ ~
La présente invention se rapporte à une chenille que l'on installe sur une bicyclette pour en améliorer la traction.
NATU RE
Il est d'usage courant, dans la cas des bicyclettes dans le cas des bicyclettes utiliser en hiver, de pédaler normalement sans que l'on puisse déraper ou parfois même avancer. On peut installer des vis ou des chaînes sur le pneu, mais ces derniers continues quand mêmes à déraper e~ même à s'enfoncer dans la neige, le fonctionnement de la bicyclette devient alors des plus pénibles.
IDEE CREATRICE
J'ai découvert que ces inconvénients peuvent être supprimées par l'installation d'une chenille à même la jante de la roue r~otrice, le prolongement et le guidage de la chenille est assuré par une roue libre disposé à la suite de la roue motrice. La distance entre l'axe de la roue libre et la roue motrice est assuré
par deux bras qui prennent appuis à même le châssis de la bicyclette. L'augmentation de la surface de contacte au sol assuré par la chenille permet l'utilisation de la bicyclette dans la neige.
Relativement aux dessins qui illustrent la réalisation de l'invention.

~La figure 3 représente la forme particulière du bras d'accouplement.~
~.La figure 4 représente le tendeur de la chenille nécessaire pour ajuster la tension La bicyclette illustré comprend une chenille qui a une section (Fig. 2) lui permettant de s'introduire dans la jante9 de la roue motrice, afin de permettre le plein contacte de la chenille avec la jante9 une seconde roue avec jante3 est nécessaire, cette dernière permet de contrôler le mouvement et la tension de la chenille' . La roue libre3 est maintenue en place par deux bras2 qui prenne leur appuis sur le châssis3 de la bicyclette, ces bras2 sont maintenue en place par les boulons' qui maintienne la roue arrière sur le châssis3. De petits collets7 sont ajouté au bras2 avec le châssis3. L'assemblage de la roue libre3 et des bras2 comporte deux tendeurs4, ces dits tendeurs sont nécessaires afin de permettre l'ajustement de la tensiondelachenille'.

GENERAL DESCRIPTION 21141 ~ ~
The present invention relates to a track which is installed on a bicycle to improve it.
traction.
NATURE
It is common practice, in the case of bicycles in the case of bicycles used in winter, to pedal normally without being able to slip or sometimes even move forward. We can install screws or chains on the tire, but these still continue to slip and even to sink in the snow, the operation of the bicycle becomes very difficult.
CREATOR IDEA
I discovered that these disadvantages can be eliminated by installing a track on the same the rim of the driving wheel, the extension and guiding of the track is ensured by a free wheel arranged after the drive wheel. The distance between the freewheel axis and the drive wheel is assured by two arms which take support from the chassis of the bicycle. The increase in the area of contact with the ground ensured by the track allows the use of the bicycle in the snow.
Relative to the drawings which illustrate the embodiment of the invention.
~ Figure 1 shows an overview of the bicycle equipped with the track and parts necessary for operation.
Figure 2 shows a sectional view A - A of the profile that must take the track ~
~ Figure 3 shows the particular shape of the coupling arm. ~
Figure 4 shows the track tensioner needed to adjust the tension The illustrated bicycle includes a caterpillar which has a section (Fig. 2) allowing it to enter in the rim9 of the drive wheel, to allow full contact of the track with the rim9 a second wheel with rim3 is necessary, the latter allows movement and tension to be controlled of the caterpillar '. The freewheel3 is held in place by two arms2 which take their support from the chassis3 of the bicycle, these arms2 are held in place by the bolts' which hold the rear wheel on the chassis 3. Small collars7 are added to the arm2 with the chassis3. The assembly of the freewheel3 and arm2 has two tensioners4, these so-called tensioners are necessary to allow the adjustment of the tensiondelachenille '. Adjusting the tension of the track is necessary in order to avoid the track slides on the walls of the drive wheel 9.

Claims

Les réalisations de l'invention, au sujet desquelles un droit exclusif de propriété ou de privilège est revendiqué, sont définies comme suit:
Une chenille qui s'adapte sur la jante de la roue motrice d'une bicyclette et qui fonctionne grâce à la tension maintenue par le reste de l'assemblage. Très facile d'installation, cette assemblage ne nécessite aucune modification au châssis de la bicyclette.
The embodiments of the invention, over which an exclusive right of property or privilege is claimed, are defined as follows:
A track that fits on the rim of the driving wheel of a bicycle and works thanks to the tension maintained by the rest of the assembly. Very easy to install, this assembly requires no modification to the bicycle chassis.
