Description

L'invention a pour objet un moyeu perfectionné à dé- montage rapide notamment pour fauteuils pour handicapés physiquels
On connaît des moyeux à démontage rapide et notamment ceux décrits dans le brevet FR 2 548 096 appartenant à la Déposante.The subject of the invention is an improved quick-release hub, in particular for armchairs for the physically handicapped.
Quick-dismounting hubs are known and in particular those described in patent FR 2 548 096 belonging to the Applicant.

Un moyeu de ce type est décrit ci-aprbs Et illustré à. A hub of this type is described below and illustrated in.

la figure 1 pour faciliter ensuite par comparaison la nature des perfectionnements apportes.Figure 1 to then facilitate by comparison the nature of the improvements made.

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'ossature (2) du fauteuil. Le palier présente à l'une de ses extrémités une butée (1-1) plaquant contre l'ossature tandis qu'un écrou (3) coopère avec la partie filetée (1-2) de l'autre extrémité 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 frame (2) of the chair. The bearing has at one of its ends a stop (1-1) pressing against the frame while a nut (3) cooperates with the threaded part (1-2) of the other end of the bearing.

Le moyeu (4) est en alliage léger monobloc et comprend deux flasques profilés (4-1) entretoisés avec des chambres intérieures (4-2) opposées et agencées pour recevoir les cages de roulement à à billes (5) recevant laxe (6) du moyeu. Cet axe de grande longueur, présente des épaulements extérieurs (6-1) et (6-2) formant butés pour les cages à billes et un trou épaulé (6) intérieurement. Cet axe comprend deux parties distinctes. The hub (4) is made of one-piece light alloy and comprises two profiled flanges (4-1) braced with inner chambers (4-2) opposite and arranged to receive the ball bearing cages (5) receiving the axis (6) of the hub. This very long axis has external shoulders (6-1) and (6-2) forming stops for the ball cages and a shoulder hole (6) internally. This axis has two distinct parts.

l'une (6-4) disposée à l'intérieur du moyeu et l'autre (6-5) débordant de celui-ci pour s'engager à coulissement à l'inté- rieur du palier ILS ) et déborder également de celui-ci. L'extré- mité de la partie débordante présente une ouverture (6-6) correspondant sensiblement au diamètre des billes (7). La partie (6- 43 de l'axe disposée en position normale dans le moyeu présente un trou épaulé à l'intérieur duquel est engagé à coulissement une tige de commande (E3. Celle-ci formant d'un coté tête (8-1) débouchant du coté extérieur du flasque à l'opposé du palier et une partie en forme de queue (8-2) de grande longueur s'enga- geant à l'intérieur de l'axe du moyeu jusqu'à son extrémité opposés.Un ressort (9) est introduit et positionné dans la cham bre. intérieure (6-7) formée dans l'axe du moyeu. Par ailleurs, l'extrémité arrière de la tige de commande présente une gorge B- 3) autorisant l'ajustement des billes (7) lors de la pénétration de l'axe du moyeu dans le palier.one (6-4) disposed inside the hub and the other (6-5) projecting from it to engage slidingly inside the bearing ILS) and also projecting from that -this. The end of the projecting part has an opening (6-6) corresponding substantially to the diameter of the balls (7). The part (6-43 of the axis disposed in normal position in the hub has a shouldered hole inside which is slidably engaged a control rod (E3. This forming on the head side (8-1 ) emerging from the outer side of the flange opposite the bearing and a tail-shaped part (8-2) of great length engaging inside the hub axis to its opposite end. A spring (9) is introduced and positioned in the inner chamber (6-7) formed in the axis of the hub, and the rear end of the control rod has a groove B- 3) 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 flèche F sur la tige de commandes (E), provoquant le déplacement de sa tige (8é) à l'encontre du ressort (9). La gorge (8-3) vient alors en regard des ouvertures (6-6) de l'axe du moyeu permettant l'échappement des billes dans ladite gorge (8-3). L'engagement de l'axe du moyeu est donc possible. Lorsque l'axe déborde de
I'autre cc:té du palier on supprime l'effort de poussée sur le bouton poussoir, celui-ci revient en arrière sous l'action d décompression du ressort de rappel provoquant du même coup l'échappement des billes hors de la gorge (8-3); lesdites billes apparaissant alors dans l'ouverture (6-6) en léger débordement pour former butée.When it is desired to ensure rapid assembly of the hub, it must first act as a push along arrow F on the control rod (E), causing the displacement of its rod (8e) against the spring (9). The groove (8-3) then comes opposite the openings (6-6) of the axis of the hub allowing the balls to escape into said groove (8-3). The engagement of the hub axis is therefore possible. When the axis extends beyond
The other cc: tee of the bearing, the pushing force is suppressed on the push button, the latter returns back under the action of decompression of the return spring causing at the same time the escape of the balls out of the groove ( 8-3); said balls then appearing in the opening (6-6) in slight overflow to form a stop.

On a prévu sur la tête du bouton poussoir, une décou- pe (8-4) délimitant la course du bouton poussoir, une goupille (10) introduite perpendiculairement dans l'axe du moyeu formant butée de fin de course. There is provided on the head of the push button, a cutout (8-4) delimiting the stroke of the push button, a pin (10) inserted perpendicularly in the axis of the hub forming end of stroke 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.

Le moyeu, selon l'art antérieur ainsi décrit est exploité. Cependant, il présente certains Inconvénients dus à la conception précédemment exposée. The hub according to the prior art thus described is used. However, it has certain disadvantages due to the design previously exposed.

En particulier, les billes disposées en bout d'axe sont extrêmement fragiles et il n'est pas rare qu'elles soient soumises a des chocs, a des détériorations lors de la manipulation des moyeux, ou lorsque ceux-ci tombent à terre Les billes qui ne sont maintenues que par un sertissage peuvent s'échapper rendant inutilisable et non sécurisant le moyeu. In particular, the balls arranged at the end of the axle are extremely fragile and it is not uncommon for them to be subjected to shocks, to deterioration when handling the hubs, or when they fall to the ground. which are only held by a crimping can escape making it unusable and not securing the hub.

En outre, on a observé des insuffisances au niveau de l'étanchéité, par la position meme des billes en bout d'axes, nuisibles au bon fonctionnement du moyeu.  In addition, shortcomings in sealing have been observed, by the very position of the balls at the end of the axes, detrimental to the proper functioning of the hub.

Un autre Inconvénient a été soulevé inhérent au coQt de fabrication élevé du moyeu compte-tenu des formes particuliè- res de la tige de commande qui doit être réalisée nécessairement en deux parties solidarisées entre elles ultérieurement et des autres aménagements intérieurs de l'axe du moyeu. Another drawback has been raised inherent in the high manufacturing cost of the hub, taking into account the particular shapes of the control rod which must necessarily be produced in two parts which are joined together subsequently and other interior arrangements of the hub axis. .

Le but recherché selon l'invention était donc de concevoir un moyeu perfectionné à démontage rapide résolvant les inconvénients précités d'un coat de revient plus réduit et am(- liorant également l'esthétique du produit. The aim sought after according to the invention was therefore to design an improved hub with rapid dismantling overcoming the aforementioned drawbacks of a more reduced and improved cost coat (- also improving the aesthetics of the product.

Belon une première caractéristique, le moyeu comprend un axe de moyeu agencé avec des ouvertures situées dans la partie débordante du moyeu, dans un plan sensiblement à l'extérieur du plan du flasque adjacent au palier, l'extrémité de celui-ci formant butée comprenant intérieurement une gorge autorisant le roulement des billes prenant appui sur un double épaulement dé- gressif formé sur la tige poussoir coulissant dans l'axe du moyeu ; ladite tige coopérant avec un moyen de rappel logé dans l'axe du moyeu et en appui sur un bouchon. According to a first characteristic, the hub comprises a hub axle arranged with openings located in the projecting part of the hub, in a plane substantially outside the plane of the flange adjacent to the bearing, the end of the latter forming a stop comprising internally a groove allowing the rolling of the balls bearing on a double decreasing shoulder formed on the push rod sliding in the axis of the hub; said rod cooperating with a return means housed in the axis of the hub and bearing on a plug.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description. These characteristics and others will emerge clearly from the following description.

Pour fixer l'objet de l'invention illustré de manière non limitative aux figures des dessins où :
la figure 1 est une vue en coupe longitudinale illus- trant un moyeu selon l'art antérieur,
la figure 2 est une vue extérieure du moyeu perfec tionné avant montage selon l'invention,
la figure 3 est une vue en coupe longitudinale selon la figure 2 après montage,
la figure 4 est une vue semblable à la figure z mals avec action sur la tige de commande.To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings where:
FIG. 1 is a view in longitudinal section illustrating a hub according to the prior art,
FIG. 2 is an external view of the perfected hub before mounting according to the invention,
FIG. 3 is a view in longitudinal section according to FIG. 2 after assembly,
Figure 4 is a view similar to Figure z mals with action on the control rod.

Le moyeu (20) en alliage léger monobloc, comprend deuXf flasques profilés (20-1) entretoisées avec des chambres intérieures (20-2) pour recevoir les moyens de roulement (21) de l'axe de moyeu (22). Cet axe de grande longueur déborde exté- rieurement du moyeu pour recevoir d'un côte le palier (23) monté fixement dans l'ossature du fauteuil å l'endroit- approprié.  The one-piece light alloy hub (20) comprises two profiled flanges (20-1) braced with internal chambers (20-2) to receive the rolling means (21) from the hub axle (22). This long axis extends beyond the hub to receive on one side the bearing (23) fixedly mounted in the frame of the chair at the appropriate place.

Ainsi qu'il apparat à la figure 3, selon une nouvelle conception du moyeu, des billes (74) sont disposées, non pas en bout d'axe du moyeu comme précédemment, mais près de l'un des flasques (2Q-1) du moyeu. Pour cela, l'axe (22) comprend dans sa partie débordante du moyeu, des ouvertures (22-1) situées dans un plan sensiblement à l'extérieur du plan du flasque (20-1) adjacent au palier (23) tandis que l'extrémité (23-1) du palier (23) formant butée est agencée intérieurement avec une gorge (23- 28 autorisant le roulement des billes
R l'intérieur d l'axe d moyeu est disposé la tige poussoir (5; autorisant par son action l'engagement du moyeu.As it appears in FIG. 3, according to a new design of the hub, balls (74) are arranged, not at the end of the axis of the hub as previously, but near one of the flanges (2Q-1) of the hub. For this, the axis (22) comprises in its projecting part of the hub, openings (22-1) located in a plane substantially outside the plane of the flange (20-1) adjacent to the bearing (23) while the end (23-1) of the bearing (23) forming a stop is arranged internally with a groove (23-28 allowing the rolling of the balls
R inside the hub axis is disposed the push rod (5; by its action allowing the engagement of the hub.

En se féférqnt à la figure 3, on voit que ladite tige (25) coulisse dans l'axe de moyeu et comprend, près de lune de ses ex- trémités, un double épaulement de section dégressive (25-1) et (25-2) adiacent à une portée arrière (25-3) de même section que la tige.Referring to FIG. 3, it can be seen that said rod (25) slides in the hub axis and comprises, near one of its ends, a double shoulder of tapering section (25-1) and (25- 2) adiacent at a rear seat (25-3) of the same section as the stem.

L'épaulement (25-1) sert en phase de repos à l'appui supérieur des billes (24) en se situant dans le plan des ouvertures (22-1) formées sur l'axe du moyeu. Dans ce cas, comptetenu de la position de la tige, les billes débordent extérieure- ment et pénètrent dans la gorge formée dans la partie formant butée du palier. The shoulder (25-1) is used in the rest phase for the upper support of the balls (24) by being in the plane of the openings (22-1) formed on the axis of the hub. In this case, taking into account the position of the rod, the balls protrude externally and penetrate into the groove formed in the stop part of the bearing.

Le second épaulement (25-2) de section plus réduite
en prolongement du premier, permet le positionnement et le lo
gement des billes lorsque la tige poussoir a été déplacée, les
dites billes étant libérées de leur zone de verrouillage par
l'éloignement de la zone d'appui initiale
Pour compléter, un moyen élastique (26) est disposé dans la partie restante de l'axe du moyeu introduite dans le palier prenant appui contre la face de la portés (25-3) de de la tige et contre la paroi arriere d'un bouchon fileté (27) cylin- drique agencé avec un évidement hexagonal intérieur pour assurer rer son réglage en position.The second shoulder (25-2) of smaller section
as an extension of the first, allows positioning and lo
management of the balls when the push rod has been moved, the
said balls being released from their locking zone by
the distance from the initial support area
To complete, an elastic means (26) is disposed in the remaining part of the axis of the hub introduced into the bearing bearing against the face of the bearing surfaces (25-3) of the rod and against the rear wall of a cylindrical threaded plug (27) arranged with an internal hexagonal recess to ensure its adjustment in position.

La réalisation du moyeu perfectionné est donc beaucoup plus simple à réaliser et il a été évalué un gain de 5 à 10 % dans les temps d'usinage des différents composants. Par ailleurs, les billes sont parfaitement protégées et a labri de toute pollution et chocs extérieurs et le moyeu possède une esthétique nouvelle,
Le moyeu perfectionné présente aussi un agehcement nouveau particulièrement adapté aux contraintes de son utilisation.The production of the improved hub is therefore much simpler to produce and a gain of 5 to 10% has been estimated in the machining times of the various components. In addition, the balls are perfectly protected and protected from any pollution and external shocks and the hub has a new aesthetic,
The improved hub also has a new age particularly suited to the constraints of its use.

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 indiqués 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 having been more especially indicated, on the contrary it embraces all variants.
