Description
ROUE POUR TRICYCLES
La présente invention concerne toutes les roues, en matière plastique en particulier, mais pas exclusivement, pour tricycles.WHEEL FOR TRICYCLES
The present invention relates to all wheels, in particular plastic material, but not exclusively, for tricycles.
A l'heure actuelle, on connaît des roues pour tricycles se composant d'une jante obtenue par des techniques de moulage par injection et d'un anneau de finition rapporté sur sa périphérie. La jante est constituée par un corps monobloc, creux et elle est particulièrement rigide, dure et bruyante au contact du sol et c'est également pour cette raison qu'elle est munie d'un anneau périphérique à même d'atténuer son comportement bruyant, ainsi que d'augmenter l'adhérence aux surfaces d'appui. Mais avant tout, un élément obtenu par injection comme celui de ladite jante ne se prête pas à l'application par pression sur celui-ci d'un bandage réalisé dans une matière différente. At the present time, wheels for tricycles are known which consist of a rim obtained by injection molding techniques and of a finishing ring attached on its periphery. The rim is formed by a monobloc, hollow body and it is particularly rigid, hard and noisy in contact with the ground and it is also for this reason that it is provided with a peripheral ring capable of attenuating its noisy behavior, as well as increasing the adhesion to the bearing surfaces. But above all, an element obtained by injection like that of said rim does not lend itself to the application by pressure thereon of a tire made of a different material.
On connaît cependant des roues pour véhicules à vitesse d'utilisation réduite, composées d'une jante matricée d'une seule pièce et munie d'un bandage rapporté. Ces roues sont robustes, ont une bonne adhérence et un comportement peu bruyant, mais sont également lourdes, s'agissant d'éléments pleins, et relativement coûteuses. Wheels for vehicles with reduced speed of use are known, however, composed of a single-piece stamped rim and fitted with an attached tire. These wheels are robust, have good grip and low noise behavior, but are also heavy, being solid elements, and relatively expensive.
On connaît par ailleurs des roues qui se composent d'une jante constituée de deux parties complémentaires, obtenues par matriçage, qui sont disposées en opposition face à face, et d'un revêtement périphérique de couverture appliqué par pression sur la jante, une fois assemblée, fait d'une matière assurant l'adhérence voulue. Le bandage concerne la périphérie de la jante sans discontinuité ni dans le sens circulaire ni dans le sens transversal et contribue par lui-même à maintenir unies les deux moitiés. Wheels are also known which consist of a rim consisting of two complementary parts, obtained by stamping, which are arranged in opposite face to face, and a peripheral covering coating applied by pressure on the rim, once assembled. , made of a material ensuring the desired adhesion. The bandage concerns the periphery of the rim without discontinuity either in the circular direction or in the transverse direction and contributes by itself to keep the two halves united.
L'objet de la présente invention consiste à proposer une roue pour des tricycles ou similaires, formée de deux parties complémentaires, obtenues par matriçage, dotées d'un revêtement de couverture périphérique respectif et munies également de moyens exerçant une interaction pour leur assemblage face à face qui permette d'obtenir la solidité voulue. The object of the present invention is to provide a wheel for tricycles or the like, formed of two complementary parts, obtained by stamping, provided with a respective peripheral covering coating and also provided with means which exert an interaction for their assembly opposite. face which allows to obtain the desired solidity.
L'avantage est que, les deux parties destinées à constituer la jante étant obtenues par matriçage, elles peuvent être réalisées selon des formes, dans des épaisseurs et avec une légèreté plus appropriées dans chacune de leurs zones. The advantage is that, the two parts intended to constitute the rim being obtained by stamping, they can be produced according to shapes, in thicknesses and with a more appropriate lightness in each of their zones.
Le bandage périphérique sera alors constitué par les deux revêtements voisins des deux éléments constitutifs de la roue et pourra intéresser, outre la bande périphérique, également les flancs de la jante. Il pourra comporter des motifs superficiels et avoir une consistance appropriés pour assurer un degré d'adhérence au sol élevé et un comportement peu bruyant, simulant dans son ensemble les aspects d'un pneumatique classique. The peripheral tire will then be formed by the two neighboring coatings of the two constituent elements of the wheel and may be of interest, in addition to the peripheral tire, also on the sides of the rim. It may include surface patterns and have an appropriate consistency to ensure a high degree of grip on the ground and a low noise behavior, simulating as a whole the aspects of a conventional tire.
Un exemple indicatif et non limitatif d'un mode de réalisation pratique de la roue proposée ici est illustré sur les dessins ci-joints sur lesquels
la figure 1 montre, séparées et vues en coupe, les deux parties complémentaires destinées à constituer la jante de roue munie de son bandage ; et
la figure 2 montre, vue en coupe, la roue finie, résultant ainsi de l'assemblage des deux parties représentées sur la figure 1.An indicative and nonlimiting example of a practical embodiment of the wheel proposed here is illustrated in the attached drawings in which
FIG. 1 shows, separated and seen in section, the two complementary parts intended to constitute the wheel rim provided with its tire; and
FIG. 2 shows, in section view, the finished wheel, thus resulting from the assembly of the two parts shown in FIG. 1.
La roue est constituée de deux parties ou coquilles complémentaires 10, 10 (voir figure 1) réalisées par matriçage, par exemple en polypropylène ou dans une autre matière. Chaque partie ou coquille 10, 10 de la roue est munie d'un bandage périphérique 11, 11 rapporté sur celle-ci, appliqué et de toute façon ancré sur la bande annulaire extérieure de la partie elle-même. The wheel consists of two complementary parts or shells 10, 10 (see FIG. 1) produced by stamping, for example made of polypropylene or another material. Each part or shell 10, 10 of the wheel is provided with a peripheral bandage 11, 11 attached to it, applied and in any case anchored on the outer annular band of the part itself.
Les deux parties de la jante sont réciproquement symétriques et sont munies de moyens, sous la forme de chevilles 12 et de manchons 12' s'encastrant l'un dans l'autre pour un accouplement et un assemblage axial, dans le plan médian, de la jante résultante. Les deux parties assemblées définissent le moyeu 13 de la jante, la bande externe 14 et les rayons 15 entre le moyeu et la bande annulaire. Certaines parties, telles que celles des zones annulaires externes 14 et des rayons 15 peuvent être creuses (voir figure 2), pour assurer la légèreté de l'article, si ce n'est pas au détriment de sa résistance évidemment. The two parts of the rim are reciprocally symmetrical and are provided with means, in the form of pins 12 and sleeves 12 'fitting one inside the other for coupling and axial assembly, in the median plane, of the resulting rim. The two assembled parts define the hub 13 of the rim, the external strip 14 and the spokes 15 between the hub and the annular strip. Certain parts, such as those of the outer annular zones 14 and the spokes 15 may be hollow (see FIG. 2), to ensure the lightness of the article, if this is not to the detriment of its resistance, of course.
Les revêtements 11, 11 de la bande externe des deux parties 10, 10 constituent directement le bandage complet de la roue par suite de l'accouplement des deux parties complémentaires et qui aura le motif superficiel permettant d'obtenir le degré d'adhérence au sol de la roue recherché. The coverings 11, 11 of the external strip of the two parts 10, 10 directly constitute the complete tire of the wheel as a result of the coupling of the two complementary parts and which will have the surface pattern making it possible to obtain the degree of grip on the ground. of the wheel sought.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation ci-dessus décrit et représenté, à partir duquel on pourra prévoir d'autres modes et d'autres formes de réalisation, sans pour autant sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described above and shown, from which one can provide other modes and other embodiments, without departing from the scope of the 'invention.
