Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention est relative à des perfectionnements aux robinets mitigeurs. Un robin. et mitigeur comporte une arrivée d'eau chaude, une arrivée d'eau froide, une chambre de mélange, un dispositif pour régler les proportions d'eau chaude et d'eau froide et une sortie de l'eau mitigée.  The present invention relates to improvements to mixing valves. A robin. and mixer includes a hot water inlet, a cold water inlet, a mixing chamber, a device for adjusting the proportions of hot water and cold water and a mixed water outlet.

De la façon connue, la chambre de mélange comporte une cloison plane, ou platine, sur laquelle débouchent les arrivées d'eau. Sur la platine est appliquée une came susceptible, par sa rotation, d'obturer totalement ou partiellement chacune des arrivées précitées.  In known manner, the mixing chamber comprises a flat partition, or plate, on which the water inlets open. On the plate is applied a cam capable, by its rotation, of completely or partially closing each of the above-mentioned arrivals.

La came comporte un arbre d'entraînement pourvu d'un bras s'étendant hors du corps du robinet, ledit bras ayant deux positions extrêmes correspondant chacune à l'obturation totale de l'une ou l'autre des arrivées d'eau.  The cam comprises a drive shaft provided with an arm extending outside the body of the valve, said arm having two extreme positions each corresponding to the total closure of one or the other of the water inlets.

Un des problèmes posé consiste à sécuriser le robinet. En effet, selon les sites, la température peut varier et il faut disposer d'un réglage pour empêcher l'usager d'ouvrir totalement l'arrivée d'eau chaude et de fermer, ainsi, l'arrivée d'eau froide.  One of the problems is to secure the tap. Indeed, according to the sites, the temperature can vary and it is necessary to have a setting to prevent the user from fully opening the hot water supply and thus closing the cold water supply.

Une solution consiste à limiter la rotation de la came à l'aide d'une butée de façon à s'opposer à la fermeture totale de l'arrivée d'eau froide.  One solution is to limit the rotation of the cam by means of a stop so as to oppose the total closure of the cold water supply.

Outre le fait que la mise en oeuvre d'une telle butée est délicate à mettre en oeuvre elle modifie le débattement du bras de commande ce qui déplait à l'usager qui a l'impression qu'on limite sa liberté de réglage. Besides the fact that the implementation of such a stop is difficult to implement it modifies the movement of the control arm which displeases the user who has the impression that his freedom of adjustment is limited.

La présente invention, qui remédie à ces inconvénients, est remarquable en ce que la came et le bras d'entraînement présentent des  The present invention, which overcomes these drawbacks, is remarkable in that the cam and the drive arm have

moyens permettant de fixer la position angulaire de la came indépendamment de celle dudit bras.  means for fixing the angular position of the cam independently of that of said arm.

Selon un mode de réalisation, l'arbre d'entraînement de la came présente des nervures longitudinales formant entre elles des rainures susceptibles de coopérer avec des nervures similaires situées sur l'alésage du bras, l'ensemble formant un crantage.  According to one embodiment, the cam drive shaft has longitudinal ribs forming between them grooves capable of cooperating with similar ribs located on the bore of the arm, the assembly forming a notch.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

En se reportant aux dessins et selon un mode de réalisation, on voit que 1 est la platine usuelle de la chambre de mélange comportant trois orifices respectivement 2,3 et 4, correspondant à l'arrivée d'eau chaude, à celle d'eau froide et au départ de l'eau mitigée.  Referring to the drawings and according to one embodiment, it can be seen that 1 is the usual plate of the mixing chamber having three orifices respectively 2,3 and 4, corresponding to the hot water supply, to that of water cold and leaving mixed water.

De la façon connue, une came 5 est appliquée contre la platine 1 et est montée sur un arbre 6 d'entraînement dont une extrémité est guidée et peut tourillonner dans l'alésage central 7, borgne, de la platine 1 formant l'un des paliers dudit arbre.  In known manner, a cam 5 is applied against the plate 1 and is mounted on a drive shaft 6, one end of which is guided and can journal in the central bore 7, blind, of the plate 1 forming one of the bearings of said tree.

De la façon connue, l'arbre 6 est entraîné par un bras schématisé, sur la figure 2 par ses deux positions extrêmes P1 et P2. Comme cela ressort des figures 2 et 3, lorsque le bras est en position P1, l'orifice d'eau chaude est totalement démasqué (fig. 2), par contre, lorsque le bras est dans la position P2 (fig. 3), c'est l'orifice d'arrivée d'eau froide qui est totalement démasqué.  In known manner, the shaft 6 is driven by an arm shown diagrammatically in FIG. 2 by its two extreme positions P1 and P2. As is apparent from FIGS. 2 and 3, when the arm is in position P1, the hot water orifice is completely exposed (fig. 2), on the other hand, when the arm is in position P2 (fig. 3), it is the cold water inlet orifice which is completely exposed.

Si la température de l'eau chaude est élevée sur le site où est implanté le robinet, l'usager qui ouvrira celui-ci en laissant le bras dans la position P1 risquera de se brûler.  If the hot water temperature is high on the site where the tap is located, the user who opens the valve leaving the arm in position P1 may burn himself.

L'un des buts de l'invention est de remédier à cet inconvénient.  One of the aims of the invention is to remedy this drawback.

Selon l'invention, l'arbre 6 présente des nervures longitudinales 8 susceptibles de coopérer avec des nervures 9, identiques, prévues sur l'alésage 10 du bras 11. Les nervures sont suffisamment nombreuses (36 par exemple) pour que le passage de l'une à l'autre entraîne une rotation relative de quelques degrés.  According to the invention, the shaft 6 has longitudinal ribs 8 capable of cooperating with ribs 9, identical, provided on the bore 10 of the arm 11. The ribs are sufficiently numerous (36 for example) for the passage of the to one another causes a relative rotation of a few degrees.

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

Comme cela ressort de la figure 6, il est donc possible par les moyens décrits ci-dessus de modifier la position angulaire de la came sans modifier celle du bras 11. Naturellement, des repères sont effectués sur l'extrémité 6a de l'arbre 6 et sur la face 11 la du bras 11 afin de pouvoir repérer le décalage opéré.  As can be seen from FIG. 6, it is therefore possible, by the means described above, to modify the angular position of the cam without modifying that of the arm 11. Naturally, marks are made on the end 6a of the shaft 6 and on the face 11 1a of the arm 11 in order to be able to identify the offset effected.

Le réglage initial consiste à faire pivoter, avec son arbre, la came 5 pour démasquer partiellement l'orifice 3 et masquer partiellement celui 2 puis à monter le bras 11 en le plaçant dans la position P1. Ce réglage est totalement"transparent"pour l'usager car il n'affecte pas la course usuelle du bras ou débattement schématisé par l'angle a sur la figure 2.  The initial adjustment consists in pivoting, with its shaft, the cam 5 in order to partially unmask the orifice 3 and partially mask the orifice 2, then to mount the arm 11 by placing it in the position P1. This adjustment is completely "transparent" for the user because it does not affect the usual travel of the arm or the movement shown schematically by the angle a in FIG. 2.

Pour un confort maximal d'utilisation, il est souhaitable que l'angle de débattement du bras 11 soit le plus important possible mais, en l'état actuel de la technique, ce débattement est limité car l'orifice permettant audit bras de sortir du corps est fonction des dimensions de ce dernier.  For maximum comfort of use, it is desirable that the angle of movement of the arm 11 is as large as possible but, in the current state of the art, this movement is limited because the orifice allowing said arm to exit from the body is a function of the dimensions of the latter.

Selon une autre caractéristique de l'invention, le bras 11 est réalisé en deux parties 12 et 13, celle 12 comportant les nervures 9 et celle 13 comportant une extension 14, formant l'organe de manoeuvre proprement dit. Comme cela ressort des dessins, les parties 12 et 13 sont, en fait, deux pignons dentés engrenant l'un avec l'autre et limités, chacun, à un secteur ne comportant que quelques dents.  According to another characteristic of the invention, the arm 11 is made in two parts 12 and 13, that 12 having the ribs 9 and that 13 having an extension 14, forming the operating member proper. As is apparent from the drawings, the parts 12 and 13 are, in fact, two toothed pinions meshing with each other and limited, each, to a sector comprising only a few teeth.

De cette façon, il est possible de placer l'axe de rotation 15 de la partie 13 tangent à la surface externe du corps du robinet et d'augmenter l'angle de débattement de l'extension 14.  In this way, it is possible to place the axis of rotation 15 of the part 13 tangent to the external surface of the valve body and to increase the angle of movement of the extension 14.

<Desc/Clms Page number 5> <Desc / Clms Page number 5>

Selon une autre caractéristique de l'invention, la pièce 13 présente deux tourillons 16 dont les paliers sont formés, sensiblement par moitié, au moyen d'un couvercle 17 et d'un berceau 18 fixé sous celui-ci, au moyen, par exemple de rondelles élastiquement déformables 19, d'un type connu.  According to another characteristic of the invention, the part 13 has two pins 16 whose bearings are formed, substantially by half, by means of a cover 17 and a cradle 18 fixed under the latter, by means, for example elastically deformable washers 19, of a known type.

Le couvercle 17 obture la partie supérieure du robinet (non représenté), et permet d'accéder à l'intérieur de ce dernier, notamment pour effectuer le réglage initial de la came. En effet, le retrait de l'ensemble13-17- 18 permet le démontage de la pièce 12 autorisant la modification du calage angulaire de la came.  The cover 17 closes the upper part of the valve (not shown), and provides access to the interior of the latter, in particular for carrying out the initial adjustment of the cam. Indeed, the removal of the assembly 13-17-18 allows the disassembly of the part 12 allowing the modification of the angular setting of the cam.

Il est à noter que la figure 12 est très schématique et que certains éléments, comme les joints d'étanchéité ou le ressort plaquant la came contre la platine, n'ont pas été représentés, car à la portée de l'homme de l'art. Le dispositif de fixation de la pièce 20, formant le second palier de l'arbre 6, n'a pas été représenté non plus. It should be noted that FIG. 12 is very schematic and that certain elements, such as the seals or the spring pressing the cam against the plate, have not been shown, because within the reach of the man of the art. The device for fixing the part 20, forming the second bearing of the shaft 6, has not been shown either.
