L'invention a pour objet un moyeu à démontage rapide notamment pour fauteuil5 pour handicapés physiques
Actuellement, les roues équipant les fauteuils pour handicapés sont montées fixement sur leur ossature ou armature. Par suite de l'utilisation de plusieurs types de fauteuils à usage divers, promenade, sportif et autres par une même personne handicapée, il s'avère nécessaire et pratique de trouver un moyen permettant facilement l'enlèvement des roues d'un type de fauteuil pour les adap ter sur un autre type de fauteuil.The subject of the invention is a quick-dismounting hub, in particular for an armchair5 for the physically handicapped.
Currently, the wheels fitted to wheelchairs for the disabled are fixedly mounted on their frame or frame. As a result of the use of several types of wheelchairs for various uses, walking, sports and others by the same disabled person, it is necessary and practical to find a means which makes it easy to remove the wheels from a type of wheelchair to adapt them to another type of armchair.
Ce but est atteint selon l'invention par un dispositif simple et fiable, combiné dans le moyeu de la roue permettant un montage et démontage rapide. This object is achieved according to the invention by a simple and reliable device, combined in the wheel hub allowing rapid assembly and disassembly.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures du dessin. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawing.
L'ensemble moyeu de roue et son dispositif de montage et démontage rapide coopère avec un palier (1) monté fixement dans un trou prévu dans l'ossaturew (2) ou armature métallique du fauteuil. I palier présente à l'une de ses extrémités une butée (11) cylindrique plaquant contre l'ossature tandis qu'un écrou (3) coopère avec la partie filetée (l2) de l'autre extrémiié du palier. The wheel hub assembly and its quick assembly and disassembly device cooperates with a bearing (1) fixedly mounted in a hole provided in the framew (2) or metal frame of the chair. I bearing has at one of its ends a cylindrical stop (11) pressing against the frame while a nut (3) cooperates with the threaded part (12) of the other end of the bearing.
Le moyeu (4) est en alliage léger monobloc et comprend de manière connue, deux flasques profilés (4 ) entretoisés avec (42 des chambres intérieures (42) opposées et agencées pour recevoir 1 les cages de roulements à billes (5) ou équivalent. Ces roulements reçoivent l'axe (6) du moyeu. Cet axe est de grande longueur. il I 2 présente des épaulements extérieurs (6l - 62) formant butée pour
3 les cages à billes, et un trou épaulé (63) intérieurement. Cet axe comprend deux parties distinctes, l'une (64) disposée à l'intérieur 5 du moyeu,-et l'autre (6 ) débordant de ceui-ci pour s'engager à coulissement à ltintérieur du palier (1) et déborder également de celui-ci.L'extrémité de la partie débordante présente une ouverture (66) correspondant sensiblement au diamètre des billes (7) dont la fonction sera précisée ci-après. La partie (64) de l'axe disposée en position normale dans le moyeu présente un trou épaulé à l'intérieur duquel est engagé à coulissement un bouton pression (8). Celui-ci de section cylindrique comprend une partie formant tête (81) débouchant du côté extérieur du flasque à l'op- posé du palier, et une partie en forme de queue t82) de grande longueur s'engageant à l'intérieur de l'axe du moyeu jusqu'à son extrémité opposée.Un moyen-de rappel à capacité élastique (9) du type ressort à boudin ou équivalent est introduit et positionné 7 dans la chambre intérieur (67) formée dans l'axe du moyeu. - Le res- sort vient ainsi en butée par ses extrémités d'une part contre 1' épaulement intérieur (63) et d'autre part contre la face arrière de la tête du bouton pression. Par ailleurs, l'extrémité arrière de la tige de celui-ci présente une gorge (83) autorisant l'ajustement des billes (7) lors de la pénétration de l'axe du moyeu dans le palier.The hub (4) is made of one-piece light alloy and comprises, in a known manner, two profiled flanges (4) braced with (42 interior chambers (42) opposite and arranged to receive 1 the ball bearing cages (5) or equivalent. These bearings receive the axis (6) of the hub. This axis is very long. It has external shoulders (6l - 62) forming a stop for
3 the ball cages, and a shoulder hole (63) internally. This axis comprises two distinct parts, one (64) disposed inside the hub 5, and the other (6) projecting from it to engage slidingly inside the bearing (1) and projecting The end of the projecting part has an opening (66) corresponding substantially to the diameter of the balls (7), the function of which will be specified below. The part (64) of the axis disposed in the normal position in the hub has a shouldered hole inside which a press button (8) is slidably engaged. This cylindrical section comprises a head portion (81) opening on the outside of the flange opposite the bearing, and a tail-shaped portion t82) of great length engaging inside the axis of the hub to its opposite end. An elastic capacity return means (9) of the coil spring type or equivalent is introduced and positioned 7 in the inner chamber (67) formed in the axis of the hub. - The spring thus comes into abutment at its ends on the one hand against the internal shoulder (63) and on the other hand against the rear face of the head of the press button. Furthermore, the rear end of the rod thereof has a groove (83) allowing the adjustment of the balls (7) during the penetration of the hub axis in the bearing.
Lorsqu'on désire assurer un montage rapide du moyeu, on doit préalablement agir en poussée selon la flèch-F sur le bouton pression (8), provoquant le déplacement de sa tige (82) à l'encon- tre du moyeu de rappel (9). La gorge (83) vient alors en regard des ouvertures (66) de l'axe du moyeu-permettant l'échappement des billes dans ladite gorge (83). L'engagement de l'axe du moyeu est donc possible.Lorsque l'axe. déborde de l'autre côté du palier, on supprime l'effort de poussée sur le bouton poussoir, celui-ci revient en arrière sous l'action de décompression du ressort de rappel provoquant du même coup l'échappement des billes hors de la gorge (83), lesdites billes apparaissant alors dans l'ouverture (66) en léger débordement pour former butée. Il faut donc une action similaire pour dégager le moyeu. When you want to ensure rapid mounting of the hub, you must first act as a push according to arrow-F on the pressure button (8), causing the displacement of its rod (82) against the return hub ( 9). The groove (83) then comes opposite the openings (66) of the axis of the hub allowing the balls to escape into said groove (83). The engagement of the hub axle is therefore possible, when the axle. overflows on the other side of the bearing, the pushing force is eliminated on the push button, the latter goes back under the decompression action of the return spring causing at the same time the escape of the balls out of the groove (83), said balls then appearing in the opening (66) in slight overflow to form a stop. A similar action is therefore necessary to disengage the hub.

On a prévu sur la tête du bouton poussoir, une découpe (84) délimitant la course du bouton poussoir, une goupille (lO) introduite perpendiculairement dans l'axe du moyeu formant butée de fin de course.
4
There is provided on the head of the push button, a cutout (84) delimiting the stroke of the push button, a pin (10) introduced perpendicularly in the axis of the hub forming end of travel stop.
Un clips (11) monté sur la partie avant de l'axe du moyeu bloque tout l'ensemble. A clip (11) mounted on the front part of the hub axle blocks the whole assembly.
On a illustré aux figures 4 à 6, une variante du dispositif de blocage et de retenue en position de l'axe du moyeu (12). Is illustrated in Figures 4 to 6, a variant of the locking and retaining device in position of the axis of the hub (12).
Celui-ci présente à son extrémité des ouvertures (12 ) obliques dans lesquelles sont disposées de manière correspondante deux languettes profilées (13) articulées entre elles à leur extrémité inférieure et escamotables ainsi qu'illustré aux figures du dessin lors de l'action sur le bouton poussoir. This has at its end oblique openings (12) in which are arranged correspondingly two profiled tabs (13) hinged together at their lower end and retractable as illustrated in the drawing figures during action on the pushbutton.
Les avantages ressortent bien de l'invention. On souligne la simplicité du dispositif, son adaptabilité aisée et son faible coût de revient. The advantages emerge clearly from the invention. The simplicity of the device is emphasized, its easy adaptability and its low cost price.
L'invention ne se limite aucunement à celui de ses modes d' application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary it embraces all variants
