Abstract

A chassis (8) fixed to the handlebars (9) is equipped with cranks (1), having a pawl (2), connected by an axle (3) on which is fixed a conical gear (5) held by a stop (4). The gear drives a flexible cable (12) connected by a rigid extension piece (13) to a second conical gear (16) fixed to the frame. This second gear drives a free wheel pinion (20), which, by means of a transmission part (21), drives a second free wheel pinion (22) fixed on the left part of the pedal (23). The chassis (8) is equipped with movable elbow supports (10). These supports rest on two parts which slide in each other, thus allowing the front arms to adapt to the crank movement.

Description

La présente invention conceme un dispositif consistant à propulser une bicydette avec les bras en complément des jambes. The present invention relates to a device consisting in propelling a bicydette with the arms in addition to the legs.

Le dispositif selon Invention permet de renforcer ou soulager faction des jambes, en ajoutant à leur mou vement de propulsion, un mouvement complémentaire exercé par la traction des bras. The device according to the invention makes it possible to strengthen or relieve the faction of the legs, by adding to their propulsion movement, a complementary movement exerted by the traction of the arms.

Ce mouvement d'ensemble faisant intervenir la seule force musculaire, permettra de plus à tut cycliste, victime d'un handicap passagé comme permanent drun de ses membres inférieurs, d'exercer cette discipli.  This overall movement, involving only muscular force, will also allow cyclists, victims of a temporary handicap as permanent members of their lower limbs, to exercise this discipline.

ne en ayant une meleure répartition de ses efforts.not having a better distribution of its efforts.

En référence à ces dessins, (Fig.1, 2 et 3), cette réalisation comporte, en plus du pédalier traditionnel, un chassis (8) fixé au guidon (9) et équipé de 2 manivelles (1) à cliquet (2) situées aux extrémités d'un axe (3) et qui actionnent dans leur mouvement de traction altemative et /ou simultanée un engrenage conique (5) maintenu par une butée (4). With reference to these drawings, (Fig. 1, 2 and 3), this embodiment comprises, in addition to the traditional crankset, a frame (8) fixed to the handlebars (9) and equipped with 2 cranks (1) with ratchet (2) located at the ends of an axis (3) and which actuate in their alternative and / or simultaneous traction movement a bevel gear (5) held by a stop (4).

Les avants bras actionnant les 2 manivelles (1) s'appuient sur leur reposecoude respectif (10) dont la mobilité est assurée par 2 pièces coulissant l'une dans rautre (11), permettant ainsi d'adapter le mouvement des avants-bras à celui des manivelles. The forearms operating the 2 cranks (1) are based on their respective elbow rests (10) whose mobility is ensured by 2 parts sliding one in the other (11), thus allowing the movement of the forearms to be adapted to that of the cranks.

L'engrenage (5), entraine à son tour la rotation d'un flexible (12). Ce flexible fixé à une piece de prolonga- tion rigide (13) maintenue au cadre (19) par un support (14) permettant sa rotation transmet son mouvement à un deuxième engrenage conique (16). Un axe (18) centré sur ce deuxième engrenage (16) conduit le mot > vement à un premier pignon à roue libre (20). Enfin, ce premier pignon (20) entraine par Fmtermédiaire d'un élément de transmission (21), de préférence par chatte, un deuxième pignon à roue libre (22) fixé à la partie gauche du pédalier.(23)
Cette association des 2 roues libres permet le libre choix aux bras drmtervenir ou pas dans leur action complémentaire sans altérer rautonomie du pédalage en sens avant, arrière comme au repos.The gear (5), in turn causes the rotation of a hose (12). This hose fixed to a rigid extension piece (13) held on the frame (19) by a support (14) allowing its rotation transmits its movement to a second bevel gear (16). An axis (18) centered on this second gear (16) leads the word> vement to a first freewheel pinion (20). Finally, this first pinion (20) drives, by means of a transmission element (21), preferably by cat, a second freewheel pinion (22) fixed to the left side of the crankset. (23)
This association of the 2 freewheels allows the free choice to the arms to intervene or not in their complementary action without altering the autonomy of pedaling in the forward direction, rear as at rest.

II peut être envisagé par la suite d'adapter un pignon à plusieurs roues libres, offrant alors des dévelop- pements multiples. It can then be envisaged to adapt a pinion to several freewheels, thus offering multiple developments.

En condusion, le dispositif fonctionne de la manière suivante:
Quand le cydiste tire les manivelles (1) I'une après rautre ou ensemble, il met en rotation un premier engre nage (5) auquel est fixé un flexible (12) relié à une pièce de prolongation rigide (13), transmettant le mouve ment à un deuxième engrenage (16) dont l'axe transmet la rotation à un premier pignon à roue libre (20). In condusion, the device works as follows:
When the cydist pulls the cranks (1) one after another or together, he rotates a first gear (5) to which is fixed a hose (12) connected to a rigid extension piece (13), transmitting the movement ment to a second gear (16) whose axis transmits rotation to a first freewheel pinion (20).

Enfin, un élément de transmission (21), de préférence par channe, relie le premier pignon (20) à un deuxième pignon (22) qui, fixé à la partie gauche du pédalier (23) entraine ce dernier. Finally, a transmission element (21), preferably by chain, connects the first pinion (20) to a second pinion (22) which, fixed to the left part of the crankset (23) drives the latter.
