Abstract
Description
La présente invention concerne un mécanisme multi-position (2,3 OU +) à monter en kit ou en série, placé à l'arrière du vélo tout terrain (ou/et autre par extension) permettant à l'utilisateur de monter une côte plus aisément en terrain accidenté (boue, terre friable, caillou...) grâce à une meilleure adhérence et une meilleure position de l'utilisateur.The present invention relates to a multi-position mechanism (2,3 OR +) to be mounted in kit or series, placed at the rear of the mountain bike (or / and other by extension) allowing the user to climb a hill more easily in rough terrain (mud, crumbly earth, pebble ...) thanks to a better grip and a better position of the user.
Tous les cycles traditionnels(VTT compris), sont équipés de roues fixes. Lors d'une utilisation normale (c'est à dire sur une route plate), il n'existe aucune difficulté de stabilité dans le temps et l'espace, ni d'adhérence. Les difficultés d'équilibre et d'adhérence surviennent lorsque l'utilisateur d'un cycle (VTT) entreprend une montée en terrain plus ou moins accidenté, plus ou moins sec, sur une surface plus ou moins compacte. Le réflexe de tout à chacun lors d'une montée à vélo est de se mettre debout sur les pédales afin de gagner en puissance et trouver ainsi une meilleure position.All traditional cycles (MTB included), are equipped with fixed wheels. During normal use (ie on a flat road), there is no difficulty of stability in time and space, nor adhesion. Difficulties of balance and adhesion occur when the user of a cycle (VTT) undertakes a rise in ground more or less uneven, more or less dry, on a more or less compact surface. The reflex of everyone to ride a bike is to stand on the pedals to gain power and find a better position.
Seulement, dans cette position précise, il y a déplacement du centre d'inertie, c'est à dire que toute la masse se retrouve déplacée sur la roue avant , les genoux tapent dans le guidon, donc il y a plus de difficultés de contrôle (surtout sur obstacle), il s'en suit une perte d'adhérence de la roue arrière (dérapage) ce qui entraîne une baisse de vitesse, et finalement il y a perte d'équilibre : et chute
Par ailleurs, si l'utilisateur s'efforce de rester assis sur sa selle pour garder le maximum d'adhérence, le problème se déplace et c'est au tour de la roue avant de perdre le contact au sol à chaque coup de pédale d'où la difficulté de se diriger et de rester en équilibre.Only, in this precise position, there is displacement of the center of inertia, that is to say that all the mass is found displaced on the front wheel, the knees type in the handlebars, so there are more difficulties of control (especially on obstacle), it follows a loss of adhesion of the rear wheel (skid) which causes a decrease of speed, and finally there is loss of balance: and fall
On the other hand, if the user tries to remain seated on his saddle to keep the maximum grip, the problem moves and it is the turn of the wheel before losing the ground contact with each pedal stroke. where the difficulty of heading and staying in balance.
Le mécanisme de l'invention permet de palier à ces différents problèmes.The mechanism of the invention makes it possible to overcome these various problems.
Il se compose d'un axe au pédalier (ou voir me me autour du pédalier) permettant l'articulation des bras inférieures du cadre tenant la roue arrière (principe du bras oscillant) et de deux montants réglables en 2 ; 3 positions (ou +) par deux tubes coulissants l'un dans l'autre amenant le cycle en
1) position normale
2 > position pente moyenne
3) position pente forte
Les tubes sont fixés sous la selle d'une part et près de l'axe de la roue d'autre part. Il y a également deux vérins à gaz permettant la levée du cadre par rapport à la roue arrière lorsque l'utilisateur se penche en avant quelque secondes durant l'opération. Le réglage des différentes positions se fait à l'aide de câbles commandés par une poignée qui permet de tirer le verrouillage formé d'un doigt s'enfonçant, ou se retirant d'un des 2en'e ou 3""" orifices déterminant les deux ou trois positions (ou +).It consists of a crank axle (or see me around the crankset) allowing the articulation of the lower arms of the frame holding the rear wheel (principle of the swingarm) and two adjustable uprights in 2; 3 positions (or +) by two sliding tubes in one another bringing the cycle in
1) normal position
2> average slope position
3) strong slope position
The tubes are fixed under the saddle on the one hand and near the axis of the wheel on the other hand. There are also two gas cylinders allowing the frame to be raised from the rear wheel when the user leans forward for a few seconds during the operation. Adjustment of the different positions is done by means of cables controlled by a handle which makes it possible to pull the locking formed by a finger sinking, or withdrawing from one of the 2en'e or 3 """orifices determining the two or three positions (or +).
Pour revenir en position normale, l'utilisateur n'a pas besoin de bouger de sa selle, il lui suffit d'actionner la poignée, et sa masse fera opposition aux 2 vérins, ramenant le cycle dans sa position initiale et commune.To return to the normal position, the user does not need to move his saddle, he just need to operate the handle, and its mass will oppose the two cylinders, bringing the cycle back to its initial and common position.
Les dessins annexés illustrent l'invention:
Les FIG 1, 2 montrent succinctement les différentes positions existantes.The accompanying drawings illustrate the invention:
FIGS. 1, 2 briefly show the different existing positions.
La FIG 3 montre succinctement la nouvelle position d'attaque du cadre face à une pente accentuée.FIG 3 briefly shows the new attack position of the frame facing an accentuated slope.
Les figures suivantes représentent en détail le mécanisme
En référence à ces dessins : la FIG 4 décrit la position normale du vélo avec son mécanisme. Les freins n'apparaissent pas sur les dessins par soucis de clarté et parce qu'il est possible d'équiper le VTT de freins à disque.
la FIG 5 décrit le mécanisme de verrouillage.The following figures represent in detail the mechanism
With reference to these drawings: FIG 4 describes the normal position of the bicycle with its mechanism. The brakes do not appear on the drawings for the sake of clarity and because it is possible to equip the mountain bike with disc brakes.
FIG 5 depicts the locking mechanism.
: la FIG 6 décrit la position en pente forte du vélo avec son mécanisme déployée. : FIG 6 describes the steep position of the bicycle with its mechanism deployed.
Le dispositif comporte du côté gauche et du côté droit de la roue arrière, un vérin à gaz (1) fixé sur ses deux axes, (un sur le bras oscillant, l'autre sur le cadre sous la selle) avec un système de guidage parallèle, composé de deux tubes carrés coulissants l'un dans l'autre
20x20 par exemple (2) fixé sur son axe (3) équipé d'un système de verrouillage (4), sur sa partie supérieure, dont le doigt s'enfonce dans un des trois oriflces (déterminant la hauteur du déploiement) du plus petit tube carré coulissant,15x15 par exemple (5) fixé sur son axe (6).The device comprises on the left side and on the right side of the rear wheel, a gas cylinder (1) fixed on its two axes, (one on the oscillating arm, the other on the frame under the saddle) with a guiding system parallel, composed of two square tubes sliding one inside the other
20x20 for example (2) fixed on its axis (3) equipped with a locking system (4), on its upper part, whose finger is sinking into one of the three oriflces (determining the height of deployment) of the smallest sliding square tube, 15x15 for example (5) fixed on its axis (6).
Le cadre du vélo est équipé d'un bras oscillant avec son axe (7).The frame of the bike is equipped with a swingarm with its axis (7).
Le système de verrouillage (4) décrit FIG 5, est commandé par câbles (8) à l'aide d'une poignée fixée sur le guidon comprimant le ressort de rappel (9) par le doigt de verrouillage (10) libérant le tube (5) lui permettant de coulisser dans le tube (2) et ainsi permettre à l'utilisateur de choisir sa position.The locking system (4) described in FIG. 5 is controlled by cables (8) by means of a handle fixed on the handlebar compressing the return spring (9) by the locking finger (10) releasing the tube ( 5) allowing it to slide in the tube (2) and thus allow the user to choose his position.
Le dispositif selon l'invention est particulièrement destiné au monde du cyclisme. The device according to the invention is particularly intended for the world of cycling.
