Abstract

The invention relates to a device making it possible to damp out the shocks felt by a cyclist and to make him comfortable while riding. It is made up of 3 springs (1) (7) (18) installed as follows: - one spring (1) under the saddle stem (5) to damp out the shocks at the coxae (hip cheek bone). The saddle stem (5) in free vertical movement abuts against the spring (1) which absorbs the shocks. - one spring (7) placed in the steering tube (10) which damps out the shocks felt by the arms knocking on the handlebar stem (9) which has permanent free vertical movement with respect to the steering tube (10). - the cross bar (top tube, horizontal tube) (17) is split into two parts, and a spring (18) is placed in the part connected to the seat tube (6) and the other part connected to the steering tube (10) abuts on this spring (18) and reduces the shocks brought about by the front wheel and felt by the trunk of the cyclist.

Description

La présente invention concerne un dispositif pour amortir les chocs au niveau des fesses et des mains. les chocs des bicyclettes sont traditionnellement amortis par les pneus et les ressorts de la selle. Le cycliste est bien souvent obligé de se relever lorsqu'il est sur un terrain non lisse : les pavets-par exemple. Même s'il roule sur une voie adaptee et regulière ; après une longue période de cyclisme l'on récent en général, pour les moins habitués en particulier, des douleurs entre les jambes et aux coxaux (os des fesses). The present invention relates to a device for absorbing shocks in the buttocks and hands. the shocks of bicycles are traditionally absorbed by the tires and the springs of the saddle. The cyclist is very often obliged to get up when he is on a non-smooth terrain: the pavets-for example. Even if he rides on a suitable and regular track; after a long period of cycling there is recent in general, for the less accustomed in particular, pain between the legs and coxals (bones of the buttocks).

La première partie du dispositif (figures 2 et 3), selon l'invention, permet de réduire les chocs transmis par la roue arrière. Il comporte un ressort (1) introduit dans le tube de selle (6) qui constitue l'absorbeur de chocs et une tige de selle (5) dont l'extrémité est introduite dans le tube de selle (6). La tige de selle (5) peut coulisser librement par rapport au tube de selle (6). Une tige métallique (2) soudée sur un support métallique (3) placé dans le tube de selle (6). Une vis (4) montée à l'extrémité de la tige métallique (2), retient le tube de selle (6) dans son mouvement d'éjection provoqué par la propulsion du ressort (1). The first part of the device (Figures 2 and 3), according to the invention, makes it possible to reduce the shocks transmitted by the rear wheel. It comprises a spring (1) inserted into the seat tube (6) which constitutes the shock absorber and a seat post (5) the end of which is introduced into the seat tube (6). The seatpost (5) can slide freely relative to the seat tube (6). A metal rod (2) welded to a metal support (3) placed in the seat tube (6). A screw (4) mounted at the end of the metal rod (2) retains the seat tube (6) in its ejection movement caused by the propulsion of the spring (1).

La deuxième partie du dispositif (figure 5) permet de réduire les chocs transmis par la roue avant au bras du cycliste, par la fixation d'un ressort (7) à la jonction entre la cuvette inférieure (8) la potence (s). Au fond du tube de direction (1), sur la tête de fourche (11), est soudée une tige métallique (12) d'une longueur égale à environ aux deux tiers de celle du tube de direction (1). The second part of the device (FIG. 5) makes it possible to reduce the shocks transmitted by the front wheel to the cyclist's arm, by fixing a spring (7) at the junction between the lower cup (8) and the stem (s). At the bottom of the steering tube (1), on the fork head (11), is welded a metal rod (12) with a length equal to about two thirds of that of the steering tube (1).

Cette longueur correspond au jeu de direction. L'intérieur des cuvettes inférieure C8) et supérieure (13) a une forme pentagonale. Un ressort (7) est introduit dans la cuvette inférieure (8). L'extrémité de la potence (9) a une forme pentagonale adaptée à la forme pentagonale des 2 cuvettes (8) (13) pour permettre d'assurer le jeu de direction. La jonction entre la potence (9) et la cuvette inférieure (8) dans le tube de direction (1) laisse apparaître la partie supérieure de la tige métallique C12), fixée dans la tête de fourche (in). Une vis cri4) est fixée sur cette partie et empêche la potence (9) d'etre propulsée hors du tube de direction par le ressort (7).This length corresponds to the headset. The interior of the lower C8) and upper (13) bowls has a pentagonal shape. A spring (7) is introduced into the lower cup (8). The end of the bracket (9) has a pentagonal shape adapted to the pentagonal shape of the 2 cups (8) (13) to allow the headset to be ensured. The junction between the stem (9) and the lower cup (8) in the steering tube (1) reveals the upper part of the metal rod C12), fixed in the fork head (in). A cri4) screw is fixed on this part and prevents the stem (9) from being propelled out of the steering tube by the spring (7).

Selon une autre forme de réalisation préférentielle, la force exercée sur le tronc du cycliste par la roue avant peut être amortie. Le tube diagonal (15) est supprimé, et est remplacé par un autre tube (16) de longueur sensiblement égale à celle du tube de direction (1). Cet autre tube (16) assure la jonction entre les tubes de direction (1) et horizontal (17). Le tube horizontal (17) est divisée en deux sections (figure 4). Un ressort (18) est introduit dans la section reliée au tube de selle (6). I1 est calé par un support métallique (19) soudé à l'intérieur du tube horizontal (17). Une tige métallique (2), dont l'extrémité est munie d'un boulon (21), est soudée sur le support (19).  According to another preferred embodiment, the force exerted on the trunk of the cyclist by the front wheel can be damped. The down tube (15) is deleted, and is replaced by another tube (16) of length substantially equal to that of the head tube (1). This other tube (16) provides the junction between the direction (1) and horizontal (17) tubes. The horizontal tube (17) is divided into two sections (Figure 4). A spring (18) is introduced into the section connected to the seat tube (6). I1 is wedged by a metal support (19) welded inside the horizontal tube (17). A metal rod (2), the end of which is provided with a bolt (21), is welded to the support (19).

La deuxième section est transpercée de par et d'autre par deux vis (22) sur lesquelles vient buter le ressort (18) en cas d'utilisation brusque du frein avant par exemple. The second section is pierced on either side by two screws (22) on which the spring (18) abuts in the event of sudden use of the front brake for example.

La force exercée sur le cycliste est amortie. Le mouvement de va (propulsion)-et-vient (compression) du ressort cri8) est limité par ces même vis (22). The force exerted on the cyclist is absorbed. The back and forth (propulsion) and back (compression) movement of the cri8 spring) is limited by these same screws (22).

Selon des modes particuliers de réalisation:
- les ressorts (1)(7)(18) peuvent être remplacés par des corps souples et résistants; par exemple: une lame métallique.According to particular embodiments:
- the springs (1) (7) (18) can be replaced by flexible and resistant bodies; for example: a metal blade.

- les mouvements de va-et-vient des tiges et tubes provoqués par les ressorts sont limités d'une autre manière; par exemple Cnon représenté): 3 tiges métalliques suffisamment solides sont soudés à la tige de selle dans sa partie supérieure à environ 1 cm en-dessous des boulons qui serrent la selle à la tige de selle (5). Ces 3 tiges sont disposés comme suit:
- une tige à l'arrière de la tige de selle (5).- the back and forth movements of the rods and tubes caused by the springs are limited in another way; for example Cnon shown): 3 sufficiently solid metal rods are welded to the seatpost in its upper part about 1 cm below the bolts which tighten the saddle to the seatpost (5). These 3 rods are arranged as follows:
- a rod at the rear of the seatpost (5).

- les 2 autres latéralement de part et d'autre de
la tige de selle (5). - the other 2 laterally on either side of
the seatpost (5).

Ces tiges coulissent dans 3 petits anneaux fixés à l'extérieur du tube de selle. Au bout des 3 tiges sont vissées 3 billes métalliques qui retiennent la selle, dans son mouvement d'éjection provoqué par la propulsion du ressort. La force exercée par la masse du cycliste est amortie par la tension du ressort (1) sur lequel vient s'appuyer l'extremité de la tige de selle (5).These rods slide in 3 small rings fixed to the outside of the seat tube. At the end of the 3 rods are screwed 3 metal balls which hold the saddle, in its ejection movement caused by the propulsion of the spring. The force exerted by the mass of the cyclist is damped by the tension of the spring (1) on which the end of the seat post (5) is supported.

- Un ressort peut être placé dans le haubans (23)
L'ensemble des dispositifs peut être adapte à tous les types de bicyclettes. - A spring can be placed in the shrouds (23)
All the devices can be adapted to all types of bicycles.
