Abstract

A flexible part (3), with a hollow body, is located inside a casing (1), closed by a hub cap (4), and internally supported on a guide (2) rotating on the axle and sliding inside the casing. The casing and the hub cap are of a diameter greater than the axle diameter allowing free translation between axle and casing. The casing and hub cap have a distance between their parallel lateral faces in relation to the distance between the lateral walls of the guide so as to form a sliding play. On the lateral sides of the guide are sliding discs (6). USE - Vibration absorption of handicap wheel chairs.

Une description plus détaillée de l'invention va être effectuée en référence aux dessins. Les figures 1 et 2 représentent respectivement en demi-coupe et vue de face le dispositif selon l'invention.A more detailed description of the invention will be made with reference to the drawings. Figures 1 and 2 show respectively in half-section and front view the device according to the invention.

En référence aux dessins joints, entre l'axe et le moyeu d'une roue est interposée une PARTIE SOUPLE (3) . Cette PARTIE SOUPLE (3) est montée sur un GUIDE (2), l'ensemble est logé et ajusté dans un CARTER (1). Un
FLASQUE (4) vient fermer le CARTER (1).With reference to the accompanying drawings, a FLEXIBLE PART (3) is interposed between the axle and the hub of a wheel. This FLEXIBLE PART (3) is mounted on a GUIDE (2), the assembly is housed and adjusted in a HOUSING (1). A
FLANGE (4) closes the CRANKCASE (1).

Pour conserver une parfaite perpendicularité entre l'axe et la roue le
CARTER (l) et le FLASQUE (4) assemblés, viennent glisser sur le GUIDE(2) assurant d'une part, le guidage latéral et ltétanchéité et d'autre part permettant le travail de la PARTIE SOUPLE (3).To maintain perfect perpendicularity between the axle and the wheel,
CRANKCASE (l) and the FLANGE (4) assembled, slide on the GUIDE (2) ensuring on the one hand, the lateral guidance and sealing and on the other hand allowing the work of the FLEXIBLE PART (3).

Le CARTER (1) peut être en métal moulé, forgé, usiné ou en matière plastique ou toute autre matière ayant une résistance suffisante.The CARTER (1) can be in molded, forged, machined metal or plastic or any other material having sufficient strength.

Le GUIDE (2) qui sert de guidage latéral et de support de la PARTIE
SOUPLE (3) pourra recevoir des DISQUES (6) de glissement et des ROULE
MENTS (5) pour le passage de l'axe. Ce GUIDE (2) peut être en métal moulé, forgé, usiné, ou en matière plastique ou toute autre matière ayant une résistance suffisante.The GUIDE (2) which serves as lateral guidance and support for the PART
FLEXIBLE (3) can receive SLIDING DISCS (6) and ROLLS
MENTS (5) for the passage of the axis. This GUIDE (2) can be in molded, forged, machined metal, or in plastic or any other material having sufficient strength.

La PARTIE SOUPLE (3), qui va servir d'amortisseur aura une souplesse variable et pourra être un pneumatique gonflable, ou non, ou une matière permettant une élasticité. Sa forme dans le cas de la figure 1 est dessinée en forme d'anneau mais pourra être de forme différente, en une ou plusieurs parties (exemple: boules les unes à côté des autres.)
Un FLASQUE (4) sera fixé au CARTER (l) au moyen de vis, de sertissage, soudage, collage ou tous autres moyens pouvant faire l'assemblage. Ce
FLASQUE (4) pourra être en métal, en matière plastique ou toute autre matière ayant une résistance suffisante.The FLEXIBLE PART (3), which will serve as a shock absorber will have variable flexibility and may be an inflatable tire, or not, or a material allowing elasticity. Its shape in the case of Figure 1 is drawn in the shape of a ring but may be of different shape, in one or more parts (example: balls next to each other.)
A FLANGE (4) will be fixed to the CARTER (l) by means of screws, crimping, welding, bonding or any other means that can make the assembly. This
FLANGE (4) may be made of metal, plastic or any other material having sufficient strength.

Les figures 3 et 4 représentent respectivement en vue de face et demi coupe le GUIDE (2) réalisé sous forme d'une pièce circulaire, du type bague, pourvu d'un alésage central dans lequel sont ici prévues deux portées de roulement, et une portée circulaire présentant en section transversale une concavité destinée à assurer le maintien en position centrée de la PARTIE SOUPLE (3) dans ce cas réalisée sous forme annulaire pleine ou creuse comme représentée en figure 1. Figures 3 and 4 respectively show a front view and a half section of the GUIDE (2) produced in the form of a circular part, of the ring type, provided with a central bore in which two bearing seats are provided, and a circular bearing having in cross section a concavity intended to ensure the maintenance in a centered position of the FLEXIBLE PART (3) in this case produced in solid or hollow annular form as shown in FIG. 1.

Le rayon de la concavité du GUIDE (2) étant supérieur à celui de la
PARTIE SOUPLE (3) peut permettre une déformation élastique de celle ci, de même que la partie intérieure du CARTER (1) est prévue cylindrique pour faciliter cette déformation. Sur la figure 4 apparaissent également les lamages assurant le positionnement des DISQUES (5) de glissement sur les côtés du dit guide, les dits disques glissant sur leur face opposée sur les faces intérieures planes et lisses du FLASQUE (4) et du CARTER (1).The radius of the concave of the GUIDE (2) being greater than that of the
FLEXIBLE PART (3) can allow an elastic deformation thereof, just as the inner part of the CARTER (1) is provided cylindrical to facilitate this deformation. In FIG. 4, the counterbores ensuring the positioning of the sliding DISCS (5) also appear on the sides of the said guide, the said discs sliding on their opposite face on the flat and smooth inner faces of the FLANGE (4) and of the CARTER (1 ).

La présente invention a été prévue pour équiper les fauteuils roulants pour handicapés physiques.The present invention has been designed to equip wheelchairs for the physically handicapped.

Ces fauteuils roulants, généralement sans équipement de suspension, ne sont pas confortables, alors que les handicapés passent souvent une grand grande partie de leur temps dans ces fauteuils. Les roues équipant ces fauteuils aporteront un confort supplémentaire.These wheelchairs, generally without suspension equipment, are not comfortable, while the disabled often spend a large part of their time in these wheelchairs. The wheels fitted to these chairs will provide additional comfort.

Les applications de ce dispositif ne sont pas limitées aux roues de fauteuils roulants et peuvent équiper des bicyclettes, chariots de manutention pour matériel fragile, etc., mais également s'appliqueront à d'autres dispositifs tournants tels que volants, poulies dans lesquels il est nécessaire d'absorber des contraintes, mais où il faut surtout conserver la perpendicularité par rapport à l'axe, à la différence d'autres systèmes incorporant des blocs amortisseurs du type "Silent-bloc" qui ne sont pas guidés. The applications of this device are not limited to the wheels of wheelchairs and can equip bicycles, handling carts for fragile material, etc., but will also apply to other rotating devices such as flywheels, pulleys in which it is necessary to absorb stresses, but where it is especially necessary to keep the perpendicularity with respect to the axis, unlike other systems incorporating shock-absorbing blocks of the "Silent-block" type which are not guided.
