Abstract

La présente invention concerne un dispositif permettant à une selle de Vélo Tout Terrain d'obtenir deux hauteurs de selle qui sont pré réglées par un système intégré sur le tube de selle à une commande fixée sur le guidon. Ce système mécanique permet donc à l'utilisateur qui ne pouvait être à l'aise dans toutes les positions rencontrées lors de sorties en Vélo Tout Terrain de choisir une hauteur de selle en fonction du terrain. Il est constitué du système mécanique placé dans la collerette (9) qui fait partie du tube (1) avec un ressort d'appel (6) qui permet la remontée ou la redescende du tube (3). Le tout est commandé sans descendre de vélo, depuis le guidon par une manette (9). Ce dispositif, selon l'inventeur, est particulièrement destiné aux pratiques du Vélo Tout Terrain que ce soit pour le grand ou le professionnel.par.The present invention relates to a device allowing a mountain bike saddle to obtain two saddle heights which are pre-adjusted by a system integrated on the seat tube to a control fixed on the handlebars. This mechanical system therefore allows the user who could not be comfortable in all the positions encountered during mountain bike outings to choose a saddle height according to the terrain. It consists of the mechanical system placed in the collar (9) which is part of the tube (1) with a call spring (6) which allows the rise or fall of the tube (3). Everything is controlled without getting off the bike, from the handlebars by a lever (9). This device, according to the inventor, is particularly intended for mountain biking, whether for adults or professionals.

Description

La présente invention concerne un dispositif permettant à une selle de vélo d'obtenir deux hauteurs de selle qui sont pré réglées par un système intégré dans le tube de selle et relié à une commande fixée sur le guidon (ex :Vélo Tout Terrain). The present invention relates to a device allowing a bicycle saddle to obtain two saddle heights which are pre-adjusted by a system integrated in the seat tube and connected to a control fixed on the handlebars (ex: Mountain Bike).

Actuellement, le Vélo Tout Terrain évolue sur deux types le terrain rencontré lors de compétitions ou de balades pratiquées par le grand public, c'est à dire des terrains plats et des terrains accidentés (trous, descentes de chemins, etc. ...). Il en résulte deux positions d'assise sur la selle
I - sur le plan routier, nous trouvons une position de selle facilitant l'enchaînement de l'effort, c'est à dire - jambes tendues
II - sur le plan du Tout Terrain, l'irrégularité du terrain ou de la piste amène l'utilisateur à prendre des positions différentes. Il faut donc être en suspension sur les jambes, c'est à dire - jambes fléchies
En conséquence, ce système mécanique présente deux positions de tubes de selle qui sont pré réglées # - jambes tendues - pour faire des plats c'est à dire la Selle haute (figure 1), # - jambes fléchies - pour faire du Tout terrain ou de la descente, c'est à dire Selle basse (figure 2).
Currently, mountain biking evolves on two types the terrain encountered during competitions or rides practiced by the general public, that is to say flat terrain and uneven terrain (holes, descents of paths, etc. ...) . This results in two sitting positions on the saddle
I - on the road plan, we find a saddle position facilitating the sequence of the effort, ie - legs stretched
II - on the All Terrain plan, the irregularity of the terrain or the track leads the user to take different positions. It is therefore necessary to be suspended on the legs, i.e. - bent legs
Consequently, this mechanical system has two positions of saddle tubes which are preset # - legs stretched out - to make dishes, ie the high saddle (figure 1), # - legs bent - to make All terrain or of the descent, ie Low saddle (Figure 2).

Si l'utilisation commence par du terrain plat, il prendra la position haute (figure 1 )en actionnant la manette 9, ce qui libère la gâche 8, et le ressort 6 fera remonter le tube 3 en position figure 1.If the use begins with flat ground, it will take the high position (figure 1) by actuating the lever 9, which releases the keeper 8, and the spring 6 will raise the tube 3 in position figure 1.

D'autre part, si l'utilisateur veut attaquer du Tout Terrain, il actionnera la manette 9 puis exercera une pression sur la selle en s'asseyant dessus, et la deuxième position se mettra automatiquement en place avec blocage par la gâche 8, c'est à dire en position basse (figure 2).On the other hand, if the user wants to attack from the All Terrain, he will actuate the lever 9 then exert a pressure on the saddle by sitting on it, and the second position will be automatically put in place with blocking by the keeper 8, c 'is to say in the low position (Figure 2).

Le système mécanique se compose donc de: un tube principal 1 identique à un tube de selle Tout Terrain normal, avec en plus en tête de ce tube 1 une collerette 2 accueillant le système mécanique (figure 3).The mechanical system therefore consists of: a main tube 1 identical to a normal All Terrain saddle tube, with at the top of this tube 1 a flange 2 housing the mechanical system (Figure 3).

un tube secondaire 3 coulissant dans le tube principal 1. Sur ce tube 3 deux encoches sont pratiquées, une en haut 5, l'autre en bas 4, ou vient placer une gâche 8 incluse dans la collerette 2 permettant le blocage du tube 3 sur les deux positions (figure 1 et figure 2).a secondary tube 3 sliding in the main tube 1. On this tube 3 two notches are made, one at the top 5, the other at the bottom 4, or comes to place a keeper 8 included in the collar 2 allowing the tube 3 to be blocked on the two positions (Figure 1 and Figure 2).

Ce déplacement est possible entre 4 et 5 grâce à un ressort 6 placé à la base du tube 1.This movement is possible between 4 and 5 thanks to a spring 6 placed at the base of the tube 1.

Ce ressort 6 permet au tube 3 de revenir automatiquement en position haute (figure 2). This spring 6 allows the tube 3 to automatically return to the high position (Figure 2).

le réglage de cette position (figure 2) est effectué par une vis 7 située à la base du tube 1. the adjustment of this position (figure 2) is carried out by a screw 7 located at the base of the tube 1.

La position basse (figure 1) est possible par libération de la gâche 8 actionnée par un câble commandé depuis le guidon par la manette 9.The low position (Figure 1) is possible by releasing the keeper 8 actuated by a cable controlled from the handlebars by the handle 9.

cette manette revient dans sa position initiale après utilisation. Il est bien entendu que cette manette permet les deux positions.this lever returns to its initial position after use. It is understood that this lever allows the two positions.

La collerette 2 accueille donc le système mécanique comportant la gâche 8.I1 est possible d'avoir un réglage de pression sur le tube 3 pour faciliter le déplacement entre les deux positions (figure 1, figure 2). Cette pression est due à un ressort 10 qui est réglable par l'intermédiaire d'une vis 1 1 qui est aussi la butée de gaine 12 venant de la manette.The flange 2 therefore accommodates the mechanical system comprising the keeper 8.I1 is possible to have a pressure adjustment on the tube 3 to facilitate movement between the two positions (Figure 1, Figure 2). This pressure is due to a spring 10 which is adjustable by means of a screw 1 1 which is also the sheath stop 12 coming from the lever.

Selon des modes particuliers de réalisation, il est impératif de réduire le frottement entre le tube l et le tube 3. De ce fait, sur l'extrémité de la gâche 8 est placé un système de roulement à billes 13 pour pallier ce problème.According to particular embodiments, it is imperative to reduce the friction between the tube l and the tube 3. Therefore, on the end of the keeper 8 is placed a ball bearing system 13 to overcome this problem.

De même, sont placées deux vis à billes 14 (figure 3) pour équilibrer la pression exercée par le ressort 10 lors du déplacement du tube 3 dans le tube 1.Likewise, two ball screws 14 (FIG. 3) are placed to balance the pressure exerted by the spring 10 during the displacement of the tube 3 in the tube 1.

Pour une question de rigidité et pour éviter la rotation du tube de selle 3, il est prévu sur ce même tube 3 trois rainures 15 sur la longueur du déplacement.For a question of rigidity and to avoid rotation of the seat tube 3, there are provided on this same tube 3 three grooves 15 along the length of the movement.

Ce dispositif est particulièrement destiné aux pratiques du vélo en général que ce soit pour le professionnel ou le grand public. This device is particularly intended for cycling in general, whether for the professional or the general public.
