Abstract
Description
La présente invention se rapporte à un tricycle pédagogique et évolutif destiné aux petits enfants. The present invention relates to an educational and upgradeable tricycle intended for small children.
On sait que chez les petits enfants, l'usage du tricycle précède celui du vélo. I1 est bon en effet que l'enfant acquière la maitrise du guidon et des pédales avant d'aborder le problème de l'équilibre propre au vélo. Les tricycles pour petits enfants sont de deux sortes, les uns ont des pédales sur la roue avant, les autres possèdent un pédalier central et une chaine entrainant les roues arrière grâce à un arbre transversal reliant lesdites roues et solidaire de l'une d'elles. Quand les pédales sont sur la roue avant, il n'y a pas d'arbre arrière mais un essieu. We know that in small children, the use of the tricycle precedes that of the bicycle. It is indeed good that the child acquires mastery of the handlebars and pedals before tackling the problem of balance proper to the bicycle. Tricycles for small children are of two kinds, some have pedals on the front wheel, others have a central crankset and a chain driving the rear wheels thanks to a transverse shaft connecting said wheels and integral with one of them . When the pedals are on the front wheel, there is no rear shaft but an axle.
Aucun de ces tricycles ne permet de dissocier dans le temps l'apprentissage du guidon et celui des pédales. Or il se trouve que tout naturellement l'enfant apprend l'usage du guidon bien avant celui des pédales, lesquelles, lors de l'apprentissage du guidon, ne sont pas necessaires. Pire, elles sont une gène pour les pieds, qu'elles soient sur la roue avant ou sur le pédalier central, car l'enfant a tendance à faire avancer le tri- cycle en ramant avec ses pieds sur le sol. Certes, les pédales sur roue avant sont moins génantes que les autres, mais dans ce cas précis- les pieds de l'enfant heurtent l'essieu arrière. None of these tricycles makes it possible to dissociate learning the handlebars and that of the pedals over time. It so happens that the child naturally learns to use the handlebars well before that of the pedals, which, when learning the handlebars, are not necessary. Worse, they are a gene for the feet, whether on the front wheel or on the central crankset, because the child tends to advance the tri-cycle by rowing with his feet on the ground. Of course, the pedals on the front wheel are less annoying than the others, but in this case - the child's feet hit the rear axle.
La présente invention propose donc un tricycle qui, dans un premier temps, n'a pas de pédales et dont l'essieu arrière n'est pas une barre droite transversale située pratiquement dans l'axe des roues, mais un élément en forme de fourche, arceau, portique ou U renversé allant d'une roue à l'autre en passant par une fixation centrale au cadre vers la selle, de sorte que, entre les deux roues, l'espace est libre et sans entraves pour les jambes et pieds de l'enfant. The present invention therefore provides a tricycle which, initially, has no pedals and whose rear axle is not a straight transverse bar located practically in the axis of the wheels, but a fork-shaped element , roll bar, gantry or inverted U going from one wheel to the other via a central fixing to the frame towards the saddle, so that, between the two wheels, the space is free and unimpeded for the legs and feet of the child.
Dans un deuxième temps, quand l'enfant a acquis la maitrise de la direction, la présente invention propose d'accrocher deux pédales amovibles à la roue avant. In a second step, when the child has acquired control of the steering, the present invention proposes to hang two removable pedals on the front wheel.
Enfin, dans un troisième temps, si l'on estime que celui du vélo n'est pas encore venu, la présente invention propose que soit accroché sous le cadre un boitier contenant le pignon de pédalier, la chaine et le pignon arrière, boitier sur lequel viennent se monter les pédales prélevées sur la roue avant et l'arbre de transmission transversal arrière. I1 va de soi qu'on peut passer directement du premier au troisième temps ou négliger, par économie, ledit troisième temps. Finally, in a third step, if it is estimated that that of the bicycle has not yet come, the present invention proposes that a box containing the bottom sprocket, the chain and the rear sprocket be hung under the frame, box on which are fitted the pedals taken from the front wheel and the rear transverse drive shaft. It goes without saying that one can go directly from the first to the third step or neglect, for reasons of economy, said third step.
D'autrescaractéristiques de l'invention ressortiront de la description ci-aprés d'un mode de réalisation donné à titre d'exemple en référence aux dessins annexés dans lesquels:
-la figure 1 est une vue en perspective simplifiée d'un tricycle dont les pédales sont accrochées à la roue avant.Other characteristics of the invention will emerge from the description below of an embodiment given by way of example with reference to the appended drawings in which:
FIG. 1 is a simplified perspective view of a tricycle, the pedals of which are attached to the front wheel.
-la figure 2 est une vue en perspective simplifiée du boitier central muni des pédales et de l'arbre de transmission arrière. FIG. 2 is a simplified perspective view of the central box provided with the pedals and the rear transmission shaft.
En se reportant à ia figure 1, on reconnait un tricycle avec un guidon 6, une fourche avant 7, une roue avant 8, une barre de cadre 4, une selle 5 et des roues arrière 1 et 1'. L'essieu arrière ne rejoint pas directement les moyeux 9 et 9' mais se compose d'une barre transversale 3 fixée au cadre en son centre prés de la selle et solidaire à ses extrémités des barres 2 et 2' sensiblement verticales qui la relient aux moyeux des roues 9 et 9'. Les barres 3, 2 et 2' forment une sorte de portique qui libère l'espace entre les roues. Sur la figure 1 apparaissent également les pédales amovibles 20 montées sur la roue avant. Referring to ia Figure 1, we recognize a tricycle with a handlebar 6, a front fork 7, a front wheel 8, a frame bar 4, a saddle 5 and rear wheels 1 and 1 '. The rear axle does not directly join the hubs 9 and 9 'but consists of a crossbar 3 fixed to the frame at its center near the saddle and secured at its ends to substantially vertical bars 2 and 2' which connect it to the wheel hubs 9 and 9 '. The bars 3, 2 and 2 'form a kind of gantry which frees up the space between the wheels. In Figure 1 also appear the removable pedals 20 mounted on the front wheel.
Sur la figure 2, on reconnait le pignon de pédalier 15, la chaine 16 et le pignon arrière 17 logés dans un boitier 10 lequel sera fixé au cadre et à la fourche arrière grâce aux bras 11 et 12, aux plaques 13 et 14 et aux écrous 19. On remarque sur cette figure 2 que les pédales 20 ont été fixées au pédalier et que l'arbre de transmission arrière 1S a pris sa place dans l'axe du pignon arrière 17. In Figure 2, we recognize the bottom sprocket 15, the chain 16 and the rear sprocket 17 housed in a housing 10 which will be fixed to the frame and the rear fork thanks to the arms 11 and 12, the plates 13 and 14 and the nuts 19. It can be seen in this FIG. 2 that the pedals 20 have been fixed to the crankset and that the rear drive shaft 1S has taken its place in the axis of the rear sprocket 17.
