Abstract

The vehicle with a drive operated by a swinging lever (13) has a horizontal frame (1) on which the user is seated, supported by two wheels (7) at the front, and one wheel (2) at the back. The user sits on a carriage (12) mounted on rollers which travels forwards and backwards as the lever is swung, as in the manner of a skiff. The feet rest against a board sloping upwards between the front wheels. A part of the chassis is connected by a spindle (6) at the front, which slopes forwards and forms an axis which enables the vehicle to be steered by leaning outwards. The lever controls a chain (15) with a return spring and driving a chain sprocket (18) mounted on the rear wheel, driving it. The sloping spindle (6) allows a lower member (10) attached to an axle between the front wheels to pivot for steering.

Description

La présente invention concerne un véhicule de sport propulsé à la main par le conducteur, les mouvements de ce dernier sont identiques à un rameur sur une embarcation appelée
AVIRON.The present invention relates to a sports vehicle propelled by hand by the driver, the movements of the latter are identical to a rower on a boat called
ROWING.

Les dispositifs connus de ce genre sont des barques légeres
Il existe également des machines a' ramer d'appartement tes inconvénients sont pour les premiers : l'obligation de plans d'eau, l'inscription à un club sportif avec toutes les exigences que cela comporte, ou l'achat d'un matériel coûteux ; pour le second : le manque de plein air indispensAble à tout bon en-rainement.Known devices of this kind are light boats
There are also apartment rowing machines your disadvantages are for the first: the obligation of water bodies, registration with a sports club with all the requirements that entails, or the purchase of equipment expensive; for the second: the lack of open air, essential to any good training.

Le dispositif suivant l'invention permet d'éviter ces inconvénients et de pratIquer ce sport traditionnel et très complet sur n'i-orte quelle route ou plage. Il devient accessible a tout le monde, et en comparaison à l'aviron, fait appel à un engin moins coûteux, car la technique employée (roue, chaines, pignon) est des plus courantes.The device according to the invention makes it possible to avoid these drawbacks and to practice this traditional and very complete sport on any road or beach. It becomes accessible to everyone, and in comparison to rowing, uses a less expensive machine, because the technique used (wheel, chains, pinion) is very common.

Le dispositif objet de l'invention est un engin à 3 ou 4 roues qui peut se déplacer, tourner, ou s'arrêter pour cela il emprunte les mouvements du rameur pour se propulser : pression des bras sur un levier, déplacement du corps d'avant en arrière sur un siège à roulettes, pieds fixés à la partie avant.The device object of the invention is a machine with 3 or 4 wheels which can move, turn, or stop for that it borrows the movements of the rower to propel: pressure of the arms on a lever, movement of the body back and forth on a wheeled seat, feet attached to the front.

La direction est assurée simultanément par le corps du conducteur qui doit se pencher du côté du virage et par ces deux pieds qui en assurent la bonne trajectoire ils sont appuyés sur l'essieu avant- de part et d'autre de l'axe de rotation incliné du train vant. Steering is provided simultaneously by the body of the driver who must lean on the side of the turn and by these two feet which ensure the correct trajectory they are supported on the front axle - on either side of the axis of rotation tilted of the front train.

and the two wheels, uncoupled $ from the rear part.

En se référant aux dessins, le numéro 1 désigne le cadre arrière du véhicule constitué de deux tubes parallèles fixés à la roue arrière (2) et relié au cadre avant & ) par un système de vérouillage composé dlun axe de rotation (4) et d'un boulon de vérouillage (5) permettant le repli du cadre avant sur le cadre arrière pour faciliter le transport (voir.Fig 6) ; le cadre avant (3) est un tube légèrement cintré ou coudé, il supporte en son extrémité un axe de rotation () soudé, légèrement incline vers l'arrière, que coiffe un tube soudé faisant partie integrante du train de direction, celui-ci est composé de deux roues (7 et 8) plus petites que la roue arrière, d'un essieu (9) reliant ces deux roues et d'un tube (10) en porte à faux et perpendiculaire à l'essieu qui renvoie l'axe de rotation central ( devant celui de l'essieu (9).Referring to the drawings, the number 1 designates the rear frame of the vehicle consisting of two parallel tubes fixed to the rear wheel (2) and connected to the front frame &) by a locking system composed of a rotation axis (4) and d '' a locking bolt (5) allowing the front frame to be folded over the rear frame to facilitate transport (see Fig. 6); the front frame (3) is a slightly bent or bent tube, it supports at its end a rotation axis () welded, slightly tilted backwards, topped by a welded tube forming an integral part of the steering gear, this one consists of two wheels (7 and 8) smaller than the rear wheel, an axle (9) connecting these two wheels and a tube (10) cantilevered and perpendicular to the axle which returns the central axis of rotation (in front of that of the axle (9).

Ce système a deux avantages 1) engin se touche dans un virage comme un vélo, le poids du conducteur se trouve ainsi déporté à l'intérieur du virage et compense la force centrifuge ; c'eet l'inclinaison vers l'arrière de l'axe de rotation (6) qui permet cette réalisation.This system has two advantages 1) machine is touched in a bend like a bicycle, the weight of the driver is thus shifted inside the bend and compensates for the centrifugal force; it is the tilt backward of the axis of rotation (6) which allows this realization.

2) la roue avant extérieur au virage se trouve déportée à l'extérieur et augmente ainsi la stabilité de l'engin (voir Fig 4). Cette cinématique est réalisée par le renvoi de 1'axe de rotation (6) devant le tran-de roues (7et 8).2) the front wheel outside the turn is offset to the outside and thus increases the stability of the machine (see Fig 4). This kinematics is achieved by returning the axis of rotation (6) to the tran-wheels (7 and 8).

Sur l'essieu (9) est fixé un tube parallèle (11j qui permet de maintenir les pieds suffisament pour ramener le siège en avant, et évite ainsi de les attacher à l'engin.On the axle (9) is fixed a parallel tube (11j which allows to hold the feet enough to bring the seat forward, and thus avoids attaching them to the vehicle.

ES fait, la direction est assurée simultanément par le déséquilibre du conducteur et contrôlé par les pieds reposant'sur l'essieu.ES done, the steering is provided simultaneously by the driver's imbalance and controlled by the feet resting on the axle.

La référence 12 désigne le siège à roulettes qui coulisse sur les deux tubes du cadre (1). The reference 12 designates the seat on casters which slides on the two tubes of the frame (1).

Le levier (13) pivote autour d'un axe (14), il entraine une chaine (15) fixée à sa partie inférieure ; il est surmonté d'un guidon ou volant (16).The lever (13) pivots about an axis (14), it drives a chain (15) fixed to its lower part; it is surmounted by a handlebar or steering wheel (16).

La chaine (15) entraine à son tour un pignon (17) denté fixé à un axe (18) perpendiculaire au châssis situé devant la roue arrière. Un ressort rappelle la chaine à la fin du mouvement de propulsion.The chain (15) in turn drives a toothed pinion (17) fixed to an axis (18) perpendicular to the chassis located in front of the rear wheel. A spring recalls the chain at the end of the propulsion movement.

L'axe entraine à son tour un autre pignon (19) qui renvoie par une autre chaine (20) le mouvement de rotation à un pignon denté (21) fixé à la roue arrière (2). Ce système de trois pignons permet de démultiplier à volonté le mouvement de va et vient du levier (13). En variante, on peut introduire à la place de l'axe (17), un changement de vitesse du type "anglais" incorporé au moyeu. D'autre part, un des trois pignons doit avoir une roue zabre pour permettre le retour du levier.The axis in turn drives another pinion (19) which returns by another chain (20) the rotational movement to a toothed pinion (21) fixed to the rear wheel (2). This system of three pinions makes it possible to multiply the movement back and forth of the lever (13) at will. Alternatively, one can introduce instead of the axis (17), a change of speed of the "English" type incorporated in the hub. On the other hand, one of the three pinions must have a zabre wheel to allow the lever to return.

Cet engin offre trole avantages importants 1) c'est un moyen de pratiquer un sport athlétique, l'AVIRON, dont on répète volontier qu'il es des plus complet parce qu'il exige l'effort simultané de tous les muscles du corps.This machine offers three major advantages: 1) it is a means of practicing an athletic sport, the ROWING, which we readily repeat that it is most complete because it requires the simultaneous effort of all the muscles of the body.

2) c'est un véhicule qui permet la promenade et le dplace- ment rapide. Il s'intègre très bien en bordure des plages, par exemple.2) it is a vehicle that allows walking and rapid movement. It fits very well on the edge of beaches, for example.

3)cet engin peut se concevoir très simplifié et devenir alors un jouet pour enfants pour l'apprentissage de l'aviron. 3) this machine can be very simplified and then become a toy for children for learning rowing.

4) il peut également se transformer en appareil de réduca- tion pour handicapés. 4) it can also be transformed into a reduction device for the disabled.
