Description
La présente demande de brevet d'invention a pour objet de protéger leThe purpose of the present patent application is to protect the
droit exclusif de production et d'exploitation de certains perfectionnements dans les palliers pour roues et assimilés, utilisés, en particulier, pour des planches sur lesquelles les enfants montent debout pour pratiquer des jeux d'équilibre et de glisse. Jusqu'à maintenant, les planches, comportaient des roulements à billes ou à rouleaux métalliques ordinaires, qui étaient source d'inconvénients, exclusive right of production and exploitation of certain improvements in the palliers for wheels and assimilated, used, in particular, for boards on which the children go up standing to practice games of balance and sliding. Until now, boards, had ordinary ball bearings or metal rollers, which were a source of inconvenience,
car ils s'oxydaient par suite de l'humidité inévitable sur les aires de glisse. because they oxidized due to the inevitable moisture on the gliding areas.
Avec la présente invention, ces inconvénients sont surmontés, comme cela est démontré ci-après, parce que, en dehors des perfectionnements formels sur chacune des parties de semblables roulements, la plupart des With the present invention, these disadvantages are overcome, as is demonstrated hereinafter, because apart from the formal improvements on each of the parts of similar bearings, most
éléments de ceux-ci sont réalisables en matière plastique. elements of these are achievable in plastic.
L'invention concerne les perfectionnements des paliers pour roues et assimilés, caractérisés en ce que l'extrémité de l'axe emmanché dans le palier, dépasse du fond d'un logement de roue, et que, dans ce logement, se trouve emprisonné dans une cage, la partie essentielle dudit palier, constitué à partir de la face d'appui du fond du logement, par un axe portant, une cage, et une bague d'appui suivie d'une collerette de même diamètre faisant partie d'un manchon coaxial à l'axe et présentant une zone centrale de liaison, suivi d'une collerette d'un diamètre supérieur, non fixée à l'axe, et qui, sur sa face externe, porte une série de protubérances régulièrement réparties, The invention relates to improvements of wheel bearings and the like, characterized in that the end of the shaft fitted in the bearing, protrudes from the bottom of a wheel housing, and that, in this housing, is trapped in a cage, the essential part of said bearing, formed from the bearing surface of the bottom of the housing, by a bearing shaft, a cage, and a bearing ring followed by a collar of the same diameter forming part of a sleeve coaxial with the axis and having a central zone of connection, followed by a collar of a larger diameter, not fixed to the axis, and which, on its outer face, carries a series of regularly distributed protuberances,
perpendiculaires au plan vertical de la collerette et parallèles à l'axe. perpendicular to the vertical plane of the flange and parallel to the axis.
Les perfectionnements envisagés en deuxième lieu pour des paliers pour roues ou assimilés, sont caractérisés, en deuxième part, en ce que les protubérances de la collerette traversent axialement des roulements permettant la rotation lorsqu'ils sont positionnés de façon à ce que les génératrices de ceux-ci soient parallèles à l'axe de rotation de la roue ou e assimilé, et que la partie des protubérances dépassant de la longueur des rouleaux est emmanchée dans les trous de la collerette d'un manchon égaux et symétriques aux protubérances tandis que, à l'extérieur de la plus'petite collerette de ce manchon traversé par le même axe, une bague d'appui est superposée à l'arbre principal portant un écrou assemblant les éléments ensemble. Tous ces éléments, à l'exception de l'axe, sont en matière plastique. Sur le dessin joint et, aux fins d'exemple, on a représenté une réalisation pratique du perfectionnement sur des roulements pour roues et The improvements considered secondly for bearings for wheels or the like, are characterized, secondly, in that the protuberances of the flange axially traverse bearings allowing rotation when they are positioned so that the generatrices of those they are parallel to the axis of rotation of the wheel or e assimilated, and that the portion of the protuberances protruding from the length of the rollers is fitted into the holes of the collar of a sleeve equal and symmetrical to the protuberances while, the outside of the smallest collar of this sleeve traversed by the same axis, a support ring is superimposed on the main shaft carrying a nut assembling the elements together. All these elements, with the exception of the axis, are made of plastic. In the accompanying drawing and, for the purpose of example, there is shown a practical embodiment of the improvement on wheel bearings and

La figure 1 représente la section transversale médiane de I'assemblage. Les figures 2 et 3 représentent le détail d'une vue de côté et Figure 1 shows the median cross section of the assembly. Figures 2 and 3 show the detail of a side view and
d'une vue de face du plateau sur lequel sont fixés les supports de rouleau. a front view of the tray on which are fixed the roll holders.
Sur les dessins, est représenté l'axe 1 avec son extrémité emmanchée dans le logement 2 de la roue. Sur cet axe sont montés, du fond vers la face, la bague d'appui 3, suivie du manchon 4 qui, sur sa collerette interne 5 porte une série de protubérances 6 régulièrement réparties sur toute sa surface, au nombre de huit dans l'exemple représenté. Ces protubérances sont introduites à travers les rouleaux tournants 7 et leurs extrémités emmanchées extérieurement 8 sont reliées à la collerette 9 d'un manchon semblable au manchon 4. A l'extérieur de la collerette de plus petit diamètre 11 de ce manchon, est placée une bague d'appui 12 suivie d'un écrou 13 sur l'axe, qui permet de régler la pression des divers éléments qui composent le roulement. Les principaux éléments du roulements demeurent enfermés dans une cage 14 qui est encastrée dans le logement de la roue et qui n'a de trous que sur des faces pour permettre le passage des In the drawings, is represented the axis 1 with its end fitted into the housing 2 of the wheel. On this axis are mounted, from the bottom towards the face, the support ring 3, followed by the sleeve 4 which, on its inner collar 5 carries a series of protuberances 6 regularly distributed over its entire surface, eight in number in the example shown. These protuberances are introduced through the rotating rollers 7 and their externally fitted ends 8 are connected to the flange 9 of a sleeve similar to the sleeve 4. Outside the flange 11 of the smaller diameter of this sleeve, is placed a support ring 12 followed by a nut 13 on the axis, which adjusts the pressure of the various elements that make up the bearing. The main elements of the bearings remain locked in a cage 14 which is embedded in the housing of the wheel and which has holes on the faces to allow the passage of
corps 4 et 10 des deux manchons.body 4 and 10 of the two sleeves.
Cette conception est celle qui permet d'obtenir un palier approprié, tous ses éléments étant faits de matière plastique, évitant les oxydations et This design is that which makes it possible to obtain a suitable bearing, all its elements being made of plastic material, avoiding oxidation and
permettant une durée de vie et une résistance à l'abrasion maximales. allowing a maximum life and resistance to abrasion.
Les perfectionnements des paliers cités dans la présente demande de brevet d'invention, seront réalisés dans les matériaux appropriés à la The improvements of the bearings mentioned in the present patent application, will be made in the materials appropriate to the
