  • this plug body is an open cylinder of low height threaded at one of its ends for securing the overflow fitting and tapped at its other end for fixing on a threaded skirt passing through the discharge hole. of said device and secured to a plate positioned around the discharge hole.
  • a valve control of this type requires, on the part of the user to exert a significant force on the upper end of the zipper when he wants to empty the sanitary appliance; in addition, such an order requires the presence of a free volume under the device large enough for the passage of the zipper.
  • the valve stem support noticeably closes the evacuation hole which impedes good flow.
  • the mechanism described in this patent is relatively complex and comprises a large number of parts. Therefore, it is relatively expensive to manufacture. In addition, because of its complexity, it is difficult to install, maintain and repair because it requires significant assembly and disassembly time.
  • valves With a view to reducing the maneuvering forces, valves have also been proposed mounted in rotation on the edge of the discharge hole.
  • the valve In order to provide for simple control members, the valve is provided located outside the sanitary appliance, under the discharge hole of said device. Arrangements of this type are described in the Swiss patents CH-A-405,179 and French FR-A-2,422,375 These pose sealing problems because the force which must be exerted on the valve to maintain it firmly leaning on its seat, against the force of the water filling the device, is too important to be obtained easily.
  • the plug described in this patent comprises a valve positioned so as to close the discharge orifice of said plug, that is to say the orifice through which it is in communication with the discharge pipe. But in this arrangement also, the valve control members close the discharge pipe of the sanitary appliance.
  • the present invention aims to provide an easy handling plug and leaving a large place for the evacuation of water.
  • the invention provides a drain, for example for sanitary appliance, of the type comprising a drain body having an upper end intended to be fixed under the drain hole of a sanitary appliance and an orifice evacuation located at a distance from said upper end and intended to be connected to an evacuation pipe, and a valve positioned so as to close said evacuation orifice, characterized in that said valve is subjected to control means penetrating into the plug body above the discharge orifice, so that said control means act on the face of the valve turned towards the inside of the plug body and do not obstruct the discharge pipe.
  • control means can indeed be external to the device and penetrate the bung body at a level located between the device and the valve, which in currently known devices would require drilling the wall of the device.
  • the valve passes from a closed position of said orifice to an open position thereof by at least one rotational movement around an axis substantially parallel to its plane.
  • control means are then provided such that they enter the plug body through an orifice in the wall of said plug body located above the discharge orifice.
  • valve movable by a rotational movement makes it possible to use control means. Indeed, for an equal stroke of the operating element, the section of the passage cleared between the valve and the discharge orifice is much larger with a valve movable in rotation than with a valve movable in translation. This makes it possible to implement control means having a short stroke and to adopt a control device comprising tilting control buttons of small bulk.
  • a cable is completely indicated which, moreover, by its flexibility makes it possible to position the control device at any point on the upper face of the device even if it is then necessary to bypass obstacles before reaching the bung body.
  • the cable can even be attached under the device in order to follow its contours without risking being caught when storing objects under the device.
  • the valve has, connected to its face facing the interior of the sanitary appliance, an arm perpendicular to its plane; the axis of rotation parallel to the plane of the valve is located at the foot of said arm.
  • valve, the arm and the axis can form a one-piece assembly obtained inexpensively by molding or be in several parts molded independently in order to better adapt the material used.
  • the cable acts in traction on the far end of the valve of the perpendicular arm.
  • the plug according to the invention can also be implemented using a valve moving in translation; the valve will always be arranged so as to close the discharge opening of the plug body, but it will be controlled from the bottom of the apparatus by a simple axial rod protruding into the apparatus through the evacuation hole of this one. Quite interestingly, said rod may depend on the basket used to avoid the passage of large waste in the evacuation pipe.

Description

L'invention concerne les bondes d'évacuation destinées par exemple à des appareils sanitaires tels que les éviers de cuisines, les lavabos, bidets ou baignoires de salles de bains.The invention relates to drain outlets intended for example for sanitary appliances such as kitchen sinks, washbasins, bidets or bath tubs in bathrooms.

Dans la présente invention, le mot bonde est utilisé pour désigner tout le dispositif reliant le fond de l'appareil sanitaire à une canalisation d'évacuation.In the present invention, the word drain is used to designate the entire device connecting the bottom of the sanitary appliance to an evacuation pipe.

Lesdites bondes d'évacuation sont d'une manière générale constituées d'un corps de bonde disposé sous l'appareil sanitaire et relié à une canalisation d'évacuation par un raccord, généralement un raccord de trop plein. Le corps de bonde est fixé sur une paroi adjacente à un trou d'évacuation de l'appareil.Said discharge hoses generally consist of a plug body disposed under the sanitary appliance and connected to an evacuation pipe by a connection, generally an overflow connection. The drain body is fixed to a wall adjacent to a discharge hole of the device.

De manière usuelle, ce corps de bonde est un cylindre ouvert de faible hauteur fileté à l'une de ses extrémités pour la solidarisation du raccord de trop plein et taraudé à son autre extrémité pour sa fixation sur une jupe filetée traversant le trou d'évacuation dudit appareil et solidaire d'un plateau positionné autour du trou d'évacuation.Usually, this plug body is an open cylinder of low height threaded at one of its ends for securing the overflow fitting and tapped at its other end for fixing on a threaded skirt passing through the discharge hole. of said device and secured to a plate positioned around the discharge hole.

De cette manière, la paroi de l'appareil sanitaire est emprisonnée entre le plateau et le raccord de trop plein.In this way, the wall of the sanitary appliance is trapped between the tray and the overflow fitting.

L'évacuation de ces appareils sanitaires se fait alors à travers le trou d'évacuation dudit appareil, le corps de bonde et le raccord de trop plein et est interrompue par un clapet dépendant du corps de bonde et obstruant le trou d'évacuation de l'appareil.The evacuation of these sanitary devices is then done through the evacuation hole of said device, the plug body and the overflow fitting and is interrupted by a valve dependent on the plug body and obstructing the evacuation hole of the 'apparatus.

La plupart des bondes d'évacuation du commerce présentent un clapet coulissant verticalement dans le trou d'évacuation. A cet effet, une queue prévue sur ledit clapet et guidée dans ledit trou d'évacuation par un support est soumise à l'action d'un doigt traversant le raccord de trop plein et commandé par une tirette montée sur le dessus de l'appareil sanitaire.Most commercial outlet bungs have a valve sliding vertically in the outlet hole. For this purpose, a tail provided on said valve and guided in said discharge hole by a support is subjected to the action of a finger passing through the overflow connection and controlled by a pull tab mounted on the top of the device. sanitary.

Une commande de clapet de ce type nécessite, de la part de l'utilisateur d'exercer une force non négligeable sur l'extrémité supérieure de la tirette lorsqu'il veut vider l'appareil sanitaire ; de plus, une telle commande nécessite la présence d'un volume libre sous l'appareil assez important pour le passage de la tirette. En outre, le support de queue de clapet obture de manière non négligeable le trou d'évacuation ce qui nuit au bon écoulement.A valve control of this type requires, on the part of the user to exert a significant force on the upper end of the zipper when he wants to empty the sanitary appliance; in addition, such an order requires the presence of a free volume under the device large enough for the passage of the zipper. In addition, the valve stem support noticeably closes the evacuation hole which impedes good flow.

C'est pourquoi, il a été souvent entrepris des recherches afin de mettre au point une bonde d'évacuation de fonctionnement amélioré.Therefore, research has often been undertaken to develop an improved drainage plug.

C'est ainsi qu'il a été proposé dans le brevet européen EP-A-0 139.808 un dispositif tournant d'actionnement à distance de deux vannes de vidange. Selon ce brevet une même poignée tournante actionne alternativement, par l'intermédiaire d'une came de commande, deux câbles Bowden reliés chacun à un levier de manoeuvre du clapet de bonde.Thus it was proposed in European patent EP-A-0 139.808 a rotating device for remote actuation of two drain valves. According to this patent, the same rotary handle alternately actuates, by means of a control cam, two Bowden cables each connected to a lever for operating the bung valve.

Le mécanisme décrit dans ce brevet est relativement complexe et comporte un grand nombre de pièces. De ce fait, il est relativement onéreux à fabriquer. En outre, du fait de sa complexité, il est délicat à poser, à entretenir et à réparer car il demande un temps de montage et démontage important.The mechanism described in this patent is relatively complex and comprises a large number of parts. Therefore, it is relatively expensive to manufacture. In addition, because of its complexity, it is difficult to install, maintain and repair because it requires significant assembly and disassembly time.

En vue de réduire les efforts de manoeuvre, on a également proposé des clapets montés en rotation sur le bord du trou d'évacuation.With a view to reducing the maneuvering forces, valves have also been proposed mounted in rotation on the edge of the discharge hole.

En effet, l'effort à exercer par l'utilisateur pour l'ouverture de tels clapets est extrêmement faible car, dès que le décollement du clapet est obtenu sur un côté de sa périphérie, la réaction de l'eau s'engouffrant dans le passage ainsi ouvert concourt à l'achèvement du mouvement de rotation de celui-ci jusqu'à sa position d'ouverture.Indeed, the effort to be exerted by the user for the opening of such valves is extremely low because, as soon as the detachment of the valve is obtained on one side of its periphery, the reaction of the water rushing into the passage thus opened contributes to the completion of the rotational movement thereof to its open position.

Afin de prévoir des organes de commande simples, le clapet est prévu situé à l'extérieur de l'appareil sanitaire, sous le trou d'évacuation dudit appareil. Des dispositions de ce type sont décrites dans les brevets Suisse CH-A- 405 179 et français FR-A-2 422 375 Celles-ci posent des problèmes d'étanchéité car la force que l'on doit exercer sur le clapet pour le maintenir fermement appuyé sur son siège, à l'encontre de la force de l'eau remplissant l'appareil, est trop importante pour être obtenue de manière aisée.In order to provide for simple control members, the valve is provided located outside the sanitary appliance, under the discharge hole of said device. Arrangements of this type are described in the Swiss patents CH-A-405,179 and French FR-A-2,422,375 These pose sealing problems because the force which must be exerted on the valve to maintain it firmly leaning on its seat, against the force of the water filling the device, is too important to be obtained easily.

Il a également été proposé, par exemple par le brevet américain US-A-1 744 105 de disposer le clapet dans l'appareil sanitaire, au-dessus du trou d'évacuation. La commande d'un tel clapet par des moyens venant de l'extérieur de l'appareil est alors très complexe et les organes traversant le conduit d'évacuation laissent alors peu de place pour l'évacuation de l'eau.It has also been proposed, for example by American patent US-A-1,744,105, to have the valve in the sanitary appliance, above the evacuation hole. Controlling such a valve by means coming from outside the apparatus is then very complex and the members passing through the evacuation conduit then leave little room for the evacuation of the water.

Il a encore été proposé par le brevet américain US-A- 3 314 083 une disposition permettant de libérer le fond de l'appareil sanitaire. La bonde décrite dans ce brevet comporte un clapet positionné de manière à obturer l'orifice d'évacuation de ladite bonde c'est-à-dire l'orifice par lequel elle est en communication avec la canalisation d'évacuation. Mais dans cette disposition également, les organes de commande du clapet obturent la canalisation d'évacuation de l'appareil sanitaire.It has also been proposed by the American patent US-A-3 314 083 a provision making it possible to free the bottom of the sanitary appliance. The plug described in this patent comprises a valve positioned so as to close the discharge orifice of said plug, that is to say the orifice through which it is in communication with the discharge pipe. But in this arrangement also, the valve control members close the discharge pipe of the sanitary appliance.

La présente invention vise à proposer une bonde de manipulation aisée et laissant une large place pour l'évacuation de l'eau.The present invention aims to provide an easy handling plug and leaving a large place for the evacuation of water.

A cet effet, l'invention propose une bonde d'évacuation, par exemple pour appareil sanitaire, du type comportant un corps de bonde présentant une extrémité supérieure destinée à être fixée sous le trou d'évacuation d'un appareil sanitaire et un orifice d'évacuation situé à distance de ladite extrémité supérieure et destiné à être relié à une canalisation d'évacuation, et un clapet positionné de manière à obturer ledit orifice d'évacuation, caractérisée en ce que ledit clapet est soumis à des moyens de commande pénétrant dans le corps de bonde au-dessus de l'orifice d'évacuation, afin que lesdits moyens de commande agissent sur la face du clapet tournée vers l'intérieur du corps de bonde et n'obstruent pas la canalisation d'évacuation.To this end, the invention provides a drain, for example for sanitary appliance, of the type comprising a drain body having an upper end intended to be fixed under the drain hole of a sanitary appliance and an orifice evacuation located at a distance from said upper end and intended to be connected to an evacuation pipe, and a valve positioned so as to close said evacuation orifice, characterized in that said valve is subjected to control means penetrating into the plug body above the discharge orifice, so that said control means act on the face of the valve turned towards the inside of the plug body and do not obstruct the discharge pipe.

Une telle disposition présente de nombreux avantages comme cela va être décrit, elle permet de libérer le fond de l'appareil dudit clapet qui peut s'avérer gênant sinon dangereux pour l'utilisateur et de ne pas obstruer la canalisation d'évacuation avec les moyens de commande en les faisant agir sur le clapet par dessus. Les moyens de commande peuvent en effet être externes à l'appareil et pénétrer dans le corps de bonde à un niveau situé entre l'appareil et le clapet, ce qui dans les dispositifs actuellement connus nécessiterait de percer la paroi de l'appareil.Such an arrangement has many advantages as will be described, it makes it possible to free the bottom of the apparatus from said valve which can prove to be annoying if not dangerous for the user and not to obstruct the evacuation pipe with the means by making them act on the valve above. The control means can indeed be external to the device and penetrate the bung body at a level located between the device and the valve, which in currently known devices would require drilling the wall of the device.

Suivant un mode de réalisation de l'invention , le clapet passe d'une position de fermeture dudit orifice à une position d'ouverture de celui-ci par au moins un mouvement de rotation autour d'un axe sensiblement parallèle à son plan.According to one embodiment of the invention, the valve passes from a closed position of said orifice to an open position thereof by at least one rotational movement around an axis substantially parallel to its plane.

Les moyens de commande sont alors prévus tels qu'ils pénètrent dans le corps de bonde par un orifice de la paroi dudit corps de bonde situé au-dessus de l'orifice d'évacuation.The control means are then provided such that they enter the plug body through an orifice in the wall of said plug body located above the discharge orifice.

Par une telle disposition, on obtient un clapet de manipulation facile puisque l'effort à exercer par l'utilisateur est faible et une évacuation très rapide de l'appareil car les moyens de commande ne se trouvent pas dans le passage emprunté par l'eau.By such an arrangement, an easy handling valve is obtained since the effort to be exerted by the user is low and a very rapid evacuation of the device because the control means are not in the passage taken by the water. .

La mise en oeuvre d'un clapet déplaçable par un mouvement de rotation permet d'utiliser des moyens de commande. En effet, pour une course égale de l'élément de manoeuvre, la section du passage dégagé entre le clapet et l'orifice d'évacuation est beaucoup plus importante avec un clapet mobile en rotation qu'avec un clapet mobile en translation. Ceci permet de mettre en oeuvre des moyens de commande ayant une course faible et d'adopter un dispositif de commande comportant des boutons de commande basculants d'encombrement peu important.The use of a valve movable by a rotational movement makes it possible to use control means. Indeed, for an equal stroke of the operating element, the section of the passage cleared between the valve and the discharge orifice is much larger with a valve movable in rotation than with a valve movable in translation. This makes it possible to implement control means having a short stroke and to adopt a control device comprising tilting control buttons of small bulk.

Pour commander un tel clapet basculant avec un effort et une course faible, un câble est tout à fait indiqué ce qui, de plus, par sa souplesse permet de positionner le dispositif de commande en n'importe quel point de la face supérieure de l'appareil même s'il est alors nécessaire de contourner des obstacles avant d'aboutir au corps de bonde.To control such a tilting valve with a small effort and a short stroke, a cable is completely indicated which, moreover, by its flexibility makes it possible to position the control device at any point on the upper face of the device even if it is then necessary to bypass obstacles before reaching the bung body.

Le câble pourra même être attaché sous l'appareil afin de suivre ses contours sans risquer d'être accroché lorsque l'on entrepose des objets sous l'appareil.The cable can even be attached under the device in order to follow its contours without risking being caught when storing objects under the device.

Dans cette disposition, le clapet présente, relié à sa face tournée vers l'intérieur de l'appareil sanitaire, un bras perpendiculaire à son plan ; l'axe de rotation parallèle au plan du clapet se situe au pied dudit bras.In this arrangement, the valve has, connected to its face facing the interior of the sanitary appliance, an arm perpendicular to its plane; the axis of rotation parallel to the plane of the valve is located at the foot of said arm.

Le clapet, le bras et l'axe peuvent former un ensemble monobloc obtenu à peu de frais par moulage ou être en plusieurs parties moulées de manière indépendantes afin de mieux adapter la matière utilisée.The valve, the arm and the axis can form a one-piece assembly obtained inexpensively by molding or be in several parts molded independently in order to better adapt the material used.

Le câble agit en traction sur l'extrémité éloignée du clapet du bras perpendiculaire.The cable acts in traction on the far end of the valve of the perpendicular arm.

La bonde selon l'invention peut également être mise en oeuvre en utilisant un clapet se déplaçant en translation ; le clapet sera toujours disposé de manière à obturer l'orifice d'évacuation du corps de bonde, mais il sera commandé à partir du fond de l'appareil par une simple tige axiale dépassant dans l'appareil à travers le trou d'évacuation de celui-ci. De manière tout à fait intéressante, ladite tige pourra dépendre du panier utilisé pour éviter le passage des gros déchets dans la canalisation d'évacuation.The plug according to the invention can also be implemented using a valve moving in translation; the valve will always be arranged so as to close the discharge opening of the plug body, but it will be controlled from the bottom of the apparatus by a simple axial rod protruding into the apparatus through the evacuation hole of this one. Quite interestingly, said rod may depend on the basket used to avoid the passage of large waste in the evacuation pipe.

Tel que représentée à la figure 1, la bonde suivant l'invention comporte un corps de bonde 1, destiné à être fixé sur une paroi 20 adjacente à un trou d'évacuation 21 d'un appareil sanitaire. A cet effet, le corps de bonde 1 présente une extrémité supérieure globalement cylindrique 11 bordée par une collerette d'appui 12 raidie par des nervures radiales 13.As shown in Figure 1, the drain according to the invention comprises a drain body 1, intended to be fixed on a wall 20 adjacent to a discharge hole 21 of a sanitary appliance. To this end, the plug body 1 has a generally cylindrical upper end 11 bordered by a support flange 12 stiffened by radial ribs 13.

De manière connue en soi, la face interne de l'extrémité supérieure 11 est taraudée afin de coopérer avec le filetage externe d'une jupe 30 d'un plateau 3.In a manner known per se, the internal face of the upper end 11 is tapped in order to cooperate with the external thread of a skirt 30 of a plate 3.

La bonde est donc fixée sur l'appareil sanitaire en vissant le plateau 3, à travers le trou d'évacuation 21, dans l'extrémité 11 du corps de bonde avec interposition d'un joint 31.The drain is therefore fixed to the sanitary appliance by screwing the plate 3, through the discharge hole 21, into the end 11 of the drain body with the interposition of a seal 31.

La figure 1 représente deux demi-vues accolées montrant les positions relatives des différents éléments au début et en fin de vissage. Comme on peut le remarquer, la jupe 30 est d'une hauteur telle que le corps de bonde 1 peut être fixé sur des parois 20 d'épaisseurs différentes.Figure 1 shows two contiguous half-views showing the relative positions of the various elements at the start and end of screwing. As can be seen, the skirt 30 is of a height such that the plug body 1 can be fixed to walls 20 of different thicknesses.

Dans le dispositif selon l'invention, le corps de bonde 1 est de grande hauteur, l'orifice d'évacuation 14 qu'il présente étant alors à distance du trou d'évacuation 21 de l'appareil sanitaire.In the device according to the invention, the plug body 1 is of great height, the discharge orifice 14 which it presents then being at a distance from the discharge hole 21 of the sanitary appliance.

C'est par cet orifice d'évacuation 14 que le corps de bonde 1 est relié à une canalisation d'évacuation 5. A cet effet, on utilise un raccord de trop plein 51 que l'on fixe par une couronne d'adaptation 52, avec interposition d'un joint 53, à la paroi 15 entourant l'orifice d'évacuation 14.It is through this discharge orifice 14 that the plug body 1 is connected to a discharge pipe 5. For this purpose, an overflow connection 51 is used which is fixed by an adapter ring 52 , with the interposition of a seal 53, to the wall 15 surrounding the discharge orifice 14.

Le clapet 6 destiné à interrompre l'évacuation de l'appareil est suivant l'invention prévu à l'extrémité inférieure du corps de bonde 1 afin d'obturer l'orifice d'évacuation 14.The valve 6 intended to interrupt the evacuation of the device is according to the invention provided at the lower end of the plug body 1 in order to close the evacuation orifice 14.

Par cette disposition, le trou d'évacuation 21 de l'appareil reste libre pour le positionnement d'un panier ajouré 310 permettant de retenir les gros déchets. Ce panier 310, amovible grâce à sa poignée axiale 311, peut être posé sur le plateau 3 et être d'assez grande dimension sans gêner le fonctionnement du clapet 6 qui est situé loin dudit trou d'évacuation 21.By this arrangement, the discharge hole 21 of the device remains free for the positioning of a perforated basket 310 making it possible to retain large waste. This basket 310, removable by virtue of its axial handle 311, can be placed on the plate 3 and be fairly large without interfering with the operation of the valve 6 which is located far from said discharge hole 21.

Le clapet 6 se présente sous la forme d'un disque 61 de diamètre sensiblement égal à celui de l'orifice 14. Le disque 61 est recouvert sur sa face tournée vers l'orifice d'un joint souple débordant 62, maintenu en place par une plaque 63 et destiné à reposer sur le pourtour de l'orifice d'évacuation 14.The valve 6 is in the form of a disc 61 of diameter substantially equal to that of the orifice 14. The disc 61 is covered on its face facing the orifice with a flexible overflowing seal 62, held in place by a plate 63 and intended to rest on the periphery of the discharge orifice 14.

Sur sa face tournée vers l'intérieur du corps de bonde 1, le clapet 6 présente un bras diamétral 64 se terminant par une portion 65 qui lui est perpendiculaire et s'éloigne de son plan en direction de l'intérieur du corps de la bonde 1, que l'on appellera bras perpendiculaire.On its face facing the inside of the plug body 1, the valve 6 has a diametral arm 64 ending in a portion 65 which is perpendicular to it and moves away from its plane in the direction of the inside of the plug body. 1, which will be called perpendicular arm.

Le bras perpendiculaire 65 porte, près de son extrémité la plus proche du disque 61 un axe 66 parallèle au plan dudit disque 61.The perpendicular arm 65 carries, near its end closest to the disc 61 an axis 66 parallel to the plane of said disc 61.

L'axe 66 pourra être rapporté dans un orifice du bras 65, mais sera de préférence moulé monobloc avec ledit bras 65 ainsi qu'avec le bras diamétral 64 et le disque 61 afin d'être obtenu de façon simple et peu onéreuse. L'axe 66 pourrait encore être solidaire du berceau 16 ; le clapet 6 serait alors monté sur ledit axe soit par clipsage soit par l'intermédiaire d'un palier lié au bras 65.The axis 66 may be attached to an opening in the arm 65, but will preferably be molded in one piece with said arm 65 as well as with the diametral arm 64 and the disc 61 so as to be obtained in a simple and inexpensive manner. The axis 66 could also be integral with the cradle 16; the valve 6 would then be mounted on said axis either by clipping or by means of a bearing linked to the arm 65.

Le montage du clapet 6 dans le corps de bonde 1 s'effectue de manière simple en positionnant l'axe 66 dans un berceau 16 prévu à cet effet sur le fond dudit corps de bonde près de l'orifice d'évacuation 14.The valve 6 is mounted in the plug body 1 in a simple manner by positioning the pin 66 in a cradle 16 provided for this purpose on the bottom of said plug body near the discharge orifice 14.

A son extrémité la plus éloignée du disque 61, le bras 65 est conformé, par exemple en fourchette 67, afin de lui solidariser les moyens de commande.At its end furthest from the disc 61, the arm 65 is shaped, for example in a fork 67, in order to secure the control means to it.

Lesdits moyens de commande sont, dans l'exemple de réalisation représenté, formés par un câble 7 tel que ceux que l'on nomme communément corde à piano.Said control means are, in the embodiment shown, formed by a cable 7 such as those commonly known as piano wire.

L'extrémité du câble 7 s'étendant à l'intérieur du corps de bonde 1 est recouverte d'un manchon 70 à extrémité élargie 71.The end of the cable 7 extending inside the plug body 1 is covered with a sleeve 70 with an enlarged end 71.

Le manchon 70 est positionné dans la fourchette 67 que présente le bras 65 avec son extrémité élargie 71 contre la face dudit bras 65 tournée vers l'intérieur du corps de bonde 1, c'est-à-dire la face du bras opposée au câble 7. De cette manière, toute traction sur ledit câble 7 est transmise au bras 65.The sleeve 70 is positioned in the fork 67 presented by the arm 65 with its enlarged end 71 against the face of said arm 65 facing towards the inside of the plug body 1, that is to say the face of the arm opposite to the cable. 7. In this way, any traction on said cable 7 is transmitted to the arm 65.

En variante, le câble 7 pourrait ne porter qu'un embout tel qu'une sphère à son extrémité.As a variant, the cable 7 could carry only one end piece such as a sphere at its end.

Le câble 7 pénètre dans le corps de bonde 1 par une tubulure de passage 17 débouchant par une ouverture 18 de la paroi du corps de bonde située légèrement au dessus du fond et face au berceau 16.The cable 7 enters the plug body 1 through a passage tube 17 opening through an opening 18 of the wall of the plug body situated slightly above the bottom and facing the cradle 16.

Un presse étoupe 8 est prévu à l'extrémité de la tubulure 17 extérieure au corps de bonde 1 afin d'assurer une fermeture étanche de celle-ci tout en permettant le passage du câble de commande 7.A cable gland 8 is provided at the end of the tube 17 external to the plug body 1 in order to ensure a tight closure of the latter while allowing the passage of the control cable 7.

Le câble 7, en tirant sur l'extrémité du bras 65, fait pivoter celui-ci, et donc le clapet 6, autour de l'axe 66 positionné sur le berceau 16 au fond du corps de bonde 1.The cable 7, by pulling on the end of the arm 65, pivots the latter, and therefore the valve 6, around the axis 66 positioned on the cradle 16 at the bottom of the plug body 1.

Le presse-étoupe 8 comporte deux chambres en communication par un passage dont le diamètre correspond sensiblement au diamètre du câble 7 non recouvert du manchon 70. La profondeur de la chambre interne détermine la course maximale du câble de commande 7. Une course très faible, de l'ordre de quelques millimètres, est suffisante pour provoquer une rotation de l'arbre 66 sur environ 15° ce qui assure une ouverture suffisante du clapet 6 pour permettre l'évacuation rapide de l'eau contenue dans l'appareil sanitaire.The cable gland 8 has two chambers in communication via a passage, the diameter of which corresponds substantially to the diameter of the cable 7 not covered by the sleeve 70. The depth of the internal chamber determines the maximum stroke of the control cable 7. A very small stroke, of the order of a few millimeters, is sufficient to cause rotation of the shaft 66 over about 15 ° which ensures sufficient opening of the valve 6 to allow rapid evacuation of the water contained in the sanitary appliance.

Pour soulever le clapet, il suffit d'une force très faible car, dès que celui-ci est décollé de l'orifice, l'eau s'engouffre dans le passage et assure elle-même l'ouverture complète du clapet. L'utilisateur n'a donc à exercer sur l'organe de commande du câble, qui sera décrit plus loin, qu'une force de quelques centaines de grammes de sorte qu'il n'aura pas l'impression de forcer ou d'avoir à vaincre une résistance quelconque pour manoeuvrer la bonde.To lift the valve, a very weak force is enough because, as soon as it is detached from the orifice, the water rushes into the passage and itself ensures the complete opening of the valve. The user therefore only has to exert on the cable control member, which will be described later, a force of a few hundred grams so that he will not have the impression of forcing or having to overcome any resistance to maneuver the plug.

Le clapet 6 est maintenu en position fermée par la pression de l'eau et n'a pas à résister à un effort important lors de son ouverture puisque, dès qu'il est entrouvert, l'eau le pousse en passant dans l'ouverture ; il peut donc être moulé en grande série dans un matériau très léger et peu onéreux.The valve 6 is kept in the closed position by the pressure of the water and does not have to withstand a significant force when it is opened since, as soon as it is ajar, the water pushes it passing through the opening ; it can therefore be mass-molded from a very light and inexpensive material.

Par souci de sécurité, afin d'éviter que le câble 7 ne se dissocie du bras 65, on peut prévoir une protection telle que, comme représenté à titre d'exemple, une demi goulotte 19 liée à la paroi du corps de bonde près de l'orifice 18 et s'étendant au-dessus du câble 7 jusqu'à l'extrémité élargie 71, c'est-à-dire jusqu'au-dessus du bras 65 du clapet 6.For safety reasons, in order to prevent the cable 7 from dissociating from the arm 65, it is possible to provide protection such as, as shown by way of example, a half-chute 19 linked to the wall of the bung body near the orifice 18 and extending above the cable 7 to the enlarged end 71, that is to say up to the top of the arm 65 of the valve 6.

On voit également qu'avec un mécanisme de bonde selon l'invention, l'orifice d'évacuation 14 est totalement dégagé de toutes les pièces qui l'encombrent dans les dispositifs habituels de bonde. De la sorte, la section d'écoulement pour un même diamètre de passage est beaucoup plus importante et l'évacuation beaucoup plus rapide.It can also be seen that with a plug mechanism according to the invention, the discharge orifice 14 is completely clear of all the parts which obstruct it in the usual plug devices. In this way, the flow section for the same passage diameter is much larger and the evacuation much faster.

La figure 2 montre une variante de réalisation du berceau 16. A la figure 1, celui-ci présentait de manière habituelle, des paliers demi-cylindriques de rayon semblable au rayon de l'axe 66. Suivant la variante de la figure 2, l'axe 66 repose sur des profils de came 90. La figure 2a montre le clapet dans sa position de fermeture de l'orifice 14 ; l'axe 66 repose sur la portion 91 de came dont la forme est celle d'une portion de cylindre.FIG. 2 shows an alternative embodiment of the cradle 16. In FIG. 1, this usually exhibits semi-cylindrical bearings of radius similar to the radius of the axis 66. According to the variant of FIG. 2, l axis 66 rests on cam profiles 90. FIG. 2a shows the valve in its position for closing the orifice 14; the axis 66 rests on the cam portion 91, the shape of which is that of a cylinder portion.

Lorsque l'on tire sur le câble de commande 7, on voit que, dans un premier temps, l'axe 66 se déplace le long de la rampe 92 oblique jusqu'à arriver dans la position représentée à la figure 2b. Au cours de ce déplacement, le clapet 6 est déplacé vers la droite de la figure 2 en même temps qu'il est soulevé et décollé de l'ouverture 14. On remarque qu'une zone plane 94 est laissée libre autour de l'ouverture 14 afin de ne pas gêner ce mouvement.When pulling on the control cable 7, we see that, at first, the axis 66 moves along the oblique ramp 92 until it reaches the position shown in Figure 2b. During this movement, the valve 6 is moved to the right of FIG. 2 at the same time as it is lifted and detached from the opening 14. It is noted that a flat area 94 is left free around the opening 14 so as not to hinder this movement.

Dans un deuxième temps, l'axe 66 étant positionné dans une nouvelle portion de cylindre 93 située à l'extremité supérieure de la came 90, l'action de traction sur le câble 7 entraîne, comme expliqué à la figure 1, le clapet 6 en rotation autour de l'axe 66. Cette commande en rotation se fait en exerçant un effort minime car elle est aidée par l'eau passant dans l'espace déjà disponible à la figure 2b entre le clapet et l'ouverture.In a second step, the axis 66 being positioned in a new portion of cylinder 93 located at the upper end of the cam 90, the pulling action on the cable 7 causes, as explained in FIG. 1, the valve 6 in rotation about the axis 66. This rotation control is done by exerting minimal effort because it is helped by the water passing through the space already available in FIG. 2b between the valve and the opening.

Les figures 3 à 5 représentent une variante préférée de mise en oeuvre de l'invention.Figures 3 to 5 show a preferred embodiment of the invention.

Dans cette variante, le clapet 206 est conformé de manière différente qu'aux figures 1 et 2. Le disque 261 est toujours recouvert sur sa face tournée vers l'orifice d'un joint souple débordant 262, maintenu en place par une plaque 263. Par contre, la forme prévue pour ledit disque 261 est sensiblement différente puisqu'il est prévu avec un embout axial 268 sur lequel on vient positionner le bras diamétral 264. Une vis 269 dont la tête est sur la face du clapet 206 tournée vers l'intérieur de l'orifice d'évacuation 14 traverse axialement ledit clapet afin de solidariser les différents éléments entre eux ; à savoir la plaque 263, le joint 262, le disque 261 et le bras diamétral 264.In this variant, the valve 206 is shaped differently than in FIGS. 1 and 2. The disc 261 is always covered on its face facing the orifice with a flexible protruding seal 262, held in place by a plate 263. On the other hand, the shape provided for said disc 261 is substantially different since it is provided with an axial tip 268 on which the diametral arm 264 is positioned. A screw 269 whose head is on the face of the valve 206 turned towards the inside of the discharge orifice 14 passes axially through said valve in order to secure the various elements together; namely the plate 263, the seal 262, the disc 261 and the diametrical arm 264.

Dans cette forme de réalisation, le bras diamétral 264 est prévu à distance de la surface du disque 261. Ce bras 264 est triangulaire en vue de profil et a une section en U ouvert en direction du disque 261.In this embodiment, the diametrical arm 264 is provided at a distance from the surface of the disc 261. This arm 264 is triangular in profile view and has a U-shaped section open towards the disc 261.

Un bras perpendiculaire 265 dépend de l'extrémité du bras diamétral 264 éloignée de l'embout axial 268 et porte à son extrémité la plus proche du disque 261 un axe 266 parallèle au plan dudit disque 261.A perpendicular arm 265 depends on the end of the diametral arm 264 remote from the axial end piece 268 and carries at its end closest to the disc 261 an axis 266 parallel to the plane of said disc 261.

Comme on peut le voir sur la figure 4, le bras 265 est formé de deux branches parallèles 255 séparées l'une de l'autre portant chacune à leur extrémité libre un renflement cylindrique 256 formant une portion de l'axe 266.As can be seen in FIG. 4, the arm 265 is formed of two parallel branches 255 separated from each other each carrying at their free end a cylindrical bulge 256 forming a portion of the axis 266.

Ces deux portions d'axe sont destinées à être positionnées dans le berceau 216 prévu à cet effet sur le fond du corps de bonde.These two axle portions are intended to be positioned in the cradle 216 provided for this purpose on the bottom of the plug body.

Comme représenté à la figure 5, le berceau 216 présente deux cavités 226 pour la mise en place de chaque renflement 256, chacun est comparable à un palier demi-cylindrique de rayon semblable au rayon des renflements 256 formant l'axe 266. Ces deux cavités sont séparées par une plaque 227 de chaque côté de laquelle devra être positionnée une branche 255. Sur la figure 3, on peut également voir l'extrémité des moyens de commande formés par un câble 7 pénétrer par la tubulure de passage 17 située sur le côté du corps de bonde 1 légèrement au-dessus du berceau 216.As shown in Figure 5, the cradle 216 has two cavities 226 for the establishment of each bulge 256, each is comparable to a semi-cylindrical bearing of radius similar to the radius of the bulges 256 forming the axis 266. These two cavities are separated by a plate 227 on each side of which a branch 255 must be positioned. In FIG. 3, one can also see the end of the control means formed by a cable 7 penetrating through the passage pipe 17 situated on the side of the bung 1 slightly above the cradle 216.

A l'extérieur du corps de bonde 1, le câble est entouré d'une gaine 207 dont l'extrémité est fixée dans un alésage interne d'une bague 272. Cette bague 272 présente un plateau 273 qui lui est perpendiculaire et qui est destiné à être appliqué contre l'extrémité filetée de la tubulure 17 par un bouchon fileté 274. Le pourtour dudit plateau 273 est conformé avec un épaulement afin de faciliter l'alignement au montage étanche.Outside the plug body 1, the cable is surrounded by a sheath 207, the end of which is fixed in an internal bore of a ring 272. This ring 272 has a plate 273 which is perpendicular to it and which is intended to be applied against the threaded end of the pipe 17 by a threaded plug 274. The periphery of said plate 273 is shaped with a shoulder in order to facilitate alignment with the sealed assembly.

La bague 272 est traversée par un alésage en trois parties. Une première, tel qu'il a déjà décrit, assure la fixation de la gaine 207 tandis qu'une deuxième est traversée de manière libre par le câble 7 et une troisième tournée vers l'intérieur du corps de bonde permet la mise en place de l'extrémité libre 275 de petit diamètre du manchon 270 dans lequel est fixée l'extrémité du câble 7.The ring 272 is crossed by a three-part bore. A first, as he has already described, ensures the fixing of the sheath 207 while a second is freely traversed by the cable 7 and a third facing inward of the plug body allows the establishment of the free end 275 of small diameter of the sleeve 270 in which the end of the cable 7 is fixed.

Ladite extrémité 275 du manchon 270 est libre en coulissement dans la bague 272 sur une distance donnée correspondant au déplacement du câble 7 nécessaire pour l'ouverture et la fermeture du clapet.Said end 275 of the sleeve 270 is free to slide in the ring 272 over a given distance corresponding to the movement of the cable 7 necessary for the opening and closing of the valve.

Le manchon 270 se présente sous la forme d'un cylindre métallique de diamètre externe légèrement inférieur au diamètre interne de la tubulure 17. Ledit cylindre porte, dans une rainure circonférentielle 276, un joint torique 277 pour assurer l'étanchéité dans la tubulure 17.The sleeve 270 is in the form of a metal cylinder with an external diameter slightly smaller than the internal diameter of the tube 17. Said cylinder carries, in a circumferential groove 276, an O-ring 277 to seal in the tube 17.

A l'extrémité du manchon 270 ne portant pas le câble 7, on prévoit une tige 278 de petit diamètre terminée par une extrémité élargie 71.At the end of the sleeve 270 not carrying the cable 7, a rod 278 of small diameter is provided, terminated by an enlarged end 71.

C'est par cette extrémité élargie 71 qu'est assurée la commande du clapet 206. A cet effet, l'extrémité , éloignée du disque 261, du bras perpendiculaire 265 et le bras diamétral 264 forment un logement 271 pour la mise en place de ladite extrémité élargie 71. Comme on peut le voir à la figure 4, les branches 255 formant le bras perpendiculaire 265 sont plus espacées à leurs extrémités inférieures et supérieures que dans leur partie médiane, ledit espacement aux extrémités étant sensiblement égale, très légèrement supérieure, au diamètre de la tige 278 mais largement plus petit que le diamètre de l'extrémité élargie 71. De cette manière, l'on peut faire coulisser l'extrémité du manchon 270 entre les deux branches 255.It is by this enlarged end 71 that the valve 206 is controlled. To this end, the end, remote from the disc 261, from the perpendicular arm 265 and the diametral arm 264 form a housing 271 for the installation of said enlarged end 71. As can be seen in FIG. 4, the branches 255 forming the perpendicular arm 265 are more spaced at their lower and upper ends than in their middle part, said spacing at the ends being substantially equal, very slightly higher, to the diameter of the rod 278 but much smaller than the diameter of the enlarged end 71. In this way, the end of the sleeve 270 can be made to slide between the two branches 255.

Pour ce faire, la tige 278 est positionnée entre les renflements 256 formant l'axe 266, avec l'extrémité élargie 71 du côté du bras perpendiculaire 265 tourné vers le clapet 206 ; puis elle est déplacée en direction du bras diamétral 264 en exerçant un effort tendant à écarter les branches 255.To do this, the rod 278 is positioned between the bulges 256 forming the axis 266, with the enlarged end 71 on the side of the perpendicular arm 265 facing the valve 206; then it is moved in the direction of the diametral arm 264 by exerting a force tending to spread the branches 255.

L'extrémité élargie 71 est ainsi positionnée dans le logement 271 formé par l'intérieur du bras diamétral 264 fermé en partie par les branches 255 du bras perpendiculaire 265.The enlarged end 71 is thus positioned in the housing 271 formed by the interior of the diametral arm 264 partially closed by the branches 255 of the perpendicular arm 265.

La disposition des figures 3 à 5 présente l'avantage qu'il n'est plus nécessaire de mettre en oeuvre la demi-goulotte 19 puisque la tige 278 est maintenue en place du fait que l'espacement des branches 255 dans leur partie médiane est inférieur à son diamètre.The arrangement of FIGS. 3 to 5 has the advantage that it is no longer necessary to use the half-chute 19 since the rod 278 is held in place because the spacing of the branches 255 in their middle part is less than its diameter.

De plus, le câble 7 étant mis en place sur le corps de bonde, la tige 278 avec son extrémité élargie 71 s'étendant alors à l'intérieur dudit corps de bonde , on monte très facilement le clapet 206 en lui faisant chevaucher ladite tige 278 jusqu'à ce que ladite extrémité élargie soit convenablement positionnée dans son logement 271. Il suffit alors de poser les renflements 256 formant l'axe de rotation 266 dans les cavités 226 du berceau 216 pour que le dispositif soit prêt à l'utilisation.In addition, the cable 7 being placed on the plug body, the rod 278 with its enlarged end 71 then extending inside said plug body, the valve 206 is very easily mounted by overlapping it. rod 278 until said enlarged end is properly positioned in its housing 271. It then suffices to place the bulges 256 forming the axis of rotation 266 in the cavities 226 of the cradle 216 so that the device is ready for use .

Cette manière de monter le clapet 206 permet également d'enlever le clapet 206 sans avoir à toucher à un autre élément du montage, en tirant simplement celui-ci vers le haut afin de procéder à toute opération de nettoyage ou de maintenance.This manner of mounting the valve 206 also makes it possible to remove the valve 206 without having to touch another element of the assembly, by simply pulling it upwards in order to carry out any cleaning or maintenance operation.

Les figures 6 à 8 représentent une troisième variante intéressante de l'invention. Dans cette variante, le clapet 306 ferme l'orifice d'évacuation 14 en étant monté mobile axialement par rapport à celui-ci.Figures 6 to 8 show a third interesting variant of the invention. In this variant, the valve 306 closes the discharge orifice 14 while being mounted to move axially relative to the latter.

On remarque en regardant la figure 6 que cette variante de réalisation utilise un corps de bonde 1 identique en grande partie à celui des autres variantes de réalisation.It is noted by looking at FIG. 6 that this alternative embodiment uses a plug body 1 which is largely identical to that of the other alternative embodiments.

Ce corps de bonde 1 ne comporte pas le berceau prévu dans les figures 1, 2 et 3. Bien que celui-ci ne gênerait en rien le fonctionnement de la bonde de la figure 6, il est préférable pour des raisons esthétiques de ne pas le prévoir ce qui est tout à fait aisé ; il suffit en effet de positionner un noyau dans le moule de fabrication du corps de bonde.This plug body 1 does not include the cradle provided in Figures 1, 2 and 3. Although it would not interfere in any way with the operation of the plug in Figure 6, it is preferable for aesthetic reasons not to predict what is quite easy; it suffices to position a core in the mold for manufacturing the bung body.

De la même manière, la tubulure 17 peut être soit inexistante, soit réalisée de la même manière mais fermée par un bouchon plein 374 avec interposition d'un joint d'étanchéité non représenté.In the same way, the tubing 17 can be either nonexistent, or produced in the same way but closed by a solid plug 374 with the interposition of a seal not shown.

Le plateau 3 muni de sa jupe 30 filetée sera également identique à celui déjà décrit. Comme on le comprend aisément, cette bonde est destinée à être montée sur les appareils existants sur lesquels il n'est pas prévu de moyens de commande manoeuvrable à distance.The plate 3 provided with its threaded skirt 30 will also be identical to that already described. As is easily understood, this plug is intended to be mounted on existing devices on which there is no provision for remotely operable control means.

Elle présente l'avantage d'être peu chère à réaliser puisque le corps de bonde et le plateau sont réutilisables avec des modifications mineures et facilement réalisées au cours de la fabrication. Le seul élément nécessitant une modification est le panier ajouré 310 et plus précisément sa poignée axiale. En effet, le panier 310 réalisé à partir d'une plaque métallique est conservé mais on fixe dans son orifice interne 312, un fût globalement cylindrique 320. Ce fût 320 est positionné par une collerette 321 contre la face interne du panier 310 et maintenu en étant monté à force ce qui est rendu possible par sa fabrication en matière plastique moulée.It has the advantage of being inexpensive to produce since the plug body and the plate are reusable with minor modifications and easily carried out during manufacture. The only element requiring modification is the perforated basket 310 and more precisely its axial handle. In fact, the basket 310 produced from a metal plate is retained, but a generally cylindrical barrel 320 is fixed in its internal orifice 312. This barrel 320 is positioned by a flange 321 against the internal face of the basket 310 and maintained in being mounted by force which is made possible by its manufacture in molded plastic.

L'alésage interne qui traverse ledit fût 320 est en deux parties ; la première 322 débouchant à l'extrémité supérieure est de diamètre supérieur à celui de la seconde 323 débouchant à l'extrémité inférieure tournée vers le clapet 306. La seconde partie 323 présente deux rainures axiales 324 prévues de préférence diamétralement opposées. Ces rainures sont de profondeur telle que leurs fonds se trouvent sur le même diamètre que la première partie 322.The internal bore which passes through said barrel 320 is in two parts; the first 322 opening at the upper end has a diameter greater than that of the second 323 opening at the lower end facing the valve 306. The second part 323 has two axial grooves 324 preferably provided diametrically opposite. These grooves are of such depth that their bottoms are on the same diameter as the first part 322.

Dans les zones situées entre les rainures 324, l'épaulement 325 raccordant les parties 322 et 323 de l'alésage interne est conformé avec des creux 326 diamétralement opposés.In the zones located between the grooves 324, the shoulder 325 connecting the parts 322 and 323 of the internal bore is shaped with diametrically opposite recesses 326.

A l'intérieur dudit fût 320 coulisse une tige 330 de commande du clapet 306. Celle-ci est soit fixée au disque 361 du clapet par une vis solidarisant la plaque 363, le joint débordant 362, le disque 361 et la tige 330, soit réalisée en un une seule pièce par moulage avec ledit disque 361.Inside said barrel 320 slides a rod 330 for controlling the valve 306. This is either fixed to the disk 361 of the valve by a screw securing the plate 363, the overflowing seal 362, the disk 361 and the rod 330, or produced in a single piece by molding with said disc 361.

La tige de commande est de diamètre tel qu'elle peut coulisser librement dans l'alésage 323. A son extrémité supérieure, la tige 330 peut être coiffée par un bouton 331 rapporté par vissage. A peu de distance en-dessous de l'embout fileté 332 destiné à la mise en place du bouton 331, la tige 330 présente deux nervures axiales 333 de dimensions telles qu'elles puissent coulisser librement dans les rainures 324 du fût 320.The control rod is of a diameter such that it can slide freely in the bore 323. At its upper end, the rod 330 can be capped by a button 331 attached by screwing. A short distance below the threaded end piece 332 intended for the fitting of the button 331, the rod 330 has two axial ribs 333 of dimensions such that they can slide freely in the grooves 324 of the barrel 320.

Dans la position représentée à la figure 6, pour laquelle le clapet 306 obture l'orifice d'évacuation 14 du corps de bonde 1, la tige 330 est positionnée dans le fût 320 avec ses nervures axiales 333 dans les rainures 324. Le clapet 306 est maintenu contre son siège par la force de l'eau dans l'appareil sanitaire.In the position shown in Figure 6, for which the valve 306 closes the discharge orifice 14 of the plug body 1, the rod 330 is positioned in the barrel 320 with its axial ribs 333 in the grooves 324. The valve 306 is held against its seat by the force of water in the sanitary appliance.

Dans la position, non représentée aux figures, pour laquelle le clapet 306 permet l'évacuation de l'eau contenue dans l'appareil, la tige 330 dépasse vers l'intérieur de l'appareil et repose par les faces inférieures 336 des nervures 333 dans les creux 326 du fût 320.In the position, not shown in the figures, for which the valve 306 allows the evacuation of the water contained in the apparatus, the rod 330 protrudes towards the interior of the apparatus and rests by the lower faces 336 of the ribs 333 in the hollows 326 of the barrel 320.

Comme on peut aisément le comprendre, lorsque l'on veut vider l'appareil, il suffit de tirer la tige de commande 330 du clapet 306 en saisissant le bouton 331 et de la faire tourner afin de positionner les faces 336 dans les creux 326.As can easily be understood, when it is desired to empty the device, it suffices to pull the control rod 330 from the valve 306 by grasping the button 331 and to rotate it in order to position the faces 336 in the recesses 326.

Bien entendu, l'évacuation se fait également lorsque les faces 336 sont en tout point de l'épaulement 325, mais la mise en oeuvre des creux 326 permet d'assurer un maintien en position du clapet 306 évitant que par des effets de l'eau circulant vers l'orifice d'évacuation 14, la tige ne bouge.Of course, the evacuation is also done when the faces 336 are at any point of the shoulder 325, but the use of the recesses 326 makes it possible to maintain the valve 306 in position, avoiding only by the effects of the water flowing to the discharge port 14, the rod does not move.

Le pied 337 de la tige de commande 330 pourra de manière avantageuse être prévu en deux parties entre lesquelles on peut interposer des entretoises afin d'adapter la longueur de la tige à la position du panier 310 par rapport à l'orifice d'évacuation 14. Cette position peut en effet varier sensiblement en fonction de l'épaisseur de la paroi 20 de l'appareil qui détermine la position relative du plateau 3 et du corps de bonde 1.The foot 337 of the control rod 330 can advantageously be provided in two parts between which spacers can be interposed in order to adapt the length of the rod to the position of the basket 310 relative to the discharge orifice 14 This position can in fact vary substantially depending on the thickness of the wall 20 of the device which determines the relative position of the plate 3 and the plug body 1.

Dans ce mode de réalisation, le clapet est démonté et remis en place très aisément en enlevant et reposant le panier 310 sur le plateau 3.In this embodiment, the valve is disassembled and replaced very easily by removing and resting the basket 310 on the plate 3.

On va maintenant décrire, en relation avec la figure 9 le dispositif de commande du câble 7 situé à l'extrémité de celui-ci qui n'est pas raccordée au clapet 6.We will now describe, in relation to FIG. 9, the cable control device 7 located at the end of the cable which is not connected to the valve 6.

Sur cette figure, on a représenté un ensemble muni de deux basculeurs pour la commande de deux bondes selon la figure 1 ou 3 respectivement installées dans chaque bac d'un évier à double bac, ou d'un lavabo à double cuvette par exemple. On comprend donc que seul l'un des basculeurs est nécessaire pour manoeuvrer la bonde représentée sur la figure 1 et l'on pourra sans sortir du cadre de l'invention utiliser des basculeurs uniques.In this figure, there is shown an assembly provided with two rockers for the control of two bungs according to FIG. 1 or 3 respectively installed in each tank of a double tank sink, or of a double bowl sink for example. It is therefore understood that only one of the rockers is necessary to operate the plug shown in Figure 1 and we can without departing from the scope of the invention use single rockers.

Dans une ouverture 23 du plan supérieur 24 de l'appareil sanitaire est engagé un boîtier 100 dont le fond comporte une tubulure filetée sur laquelle vient se visser un écrou ou une couronne de blocage 101. A proximité du bord de cette tubulure, le fond du boîtier 100 porte au moins un pivot 102 sur lequel est articulée une palette 72, susceptible de basculer, à l'une des extrémités de laquelle est accrochée l'extrémité du câble 7, par tout moyen approprié.In an opening 23 in the upper plane 24 of the sanitary appliance is engaged a housing 100, the bottom of which comprises a threaded tube onto which a nut or a locking ring 101 is screwed. Near the edge of this tube, the bottom of the housing 100 carries at least one pivot 102 on which is articulated a pallet 72, capable of tilting, at one of the ends of which the end of the cable 7 is hung, by any suitable means.

L'extrémité inférieure du boîtier 100 se raccorde à une gaine 103 constituée par un tube fermé près de l'une de ses extrémités et percée de deux trous pour le passage de chacun des câbles 7.The lower end of the housing 100 is connected to a sheath 103 formed by a closed tube near one of its ends and pierced with two holes for the passage of each of the cables 7.

Le dessus du boîtier 100 est fermé par une membrane 104 souple et étanche qui permet la manoeuvre des palettes 72 directement à travers ladite membrane.The top of the housing 100 is closed by a flexible and waterproof membrane 104 which allows the operation of the pallets 72 directly through said membrane.

On voit que la hauteur de bascule est très faible en raison de la course très réduite du câble nécessaire à l'ouverture maximale du clapet 6, de sorte que le boîtier de manoeuvre 100 peut être relativement plat et ne faire qu'une faible saillie à la surface de l'appareil sanitaire.It can be seen that the rocker height is very small due to the very reduced travel of the cable necessary for the maximum opening of the valve 6, so that the control unit 100 can be relatively flat and only make a slight projection at the surface of the sanitary appliance.

La figure 10 représente une variante de réalisation d'un ensemble muni de basculeurs pour la commande d'un dispositif selon l'invention.FIG. 10 represents an alternative embodiment of an assembly provided with rockers for controlling a device according to the invention.

Sur cette figure, on a coupé l'ensemble au niveau d'un basculeur, le second s'il est prévu est situé derrière avec son axe dans le prolongement de celui du basculeur visible.In this figure, the assembly has been cut at a rocker, the second, if provided, is located behind with its axis in line with that of the visible rocker.

On retrouve sur cette figure le boîtier 100 traversant par une tubulure filetée 110 une ouverture 23 du plan supérieur 24 de l'appareil sanitaire et étant maintenu en place par une couronne de blocage 101. Le boîtier 100 est réalisé en deux parties , une plaque plane 109 dont dépend la tubulure 110 et un couvercle 108.We find in this figure the housing 100 passing through a threaded pipe 110 an opening 23 of the upper plane 24 of the sanitary appliance and being held in place by a locking ring 101. The housing 100 is made in two parts, a flat plate 109 on which the tubing 110 and a cover 108 depend.

Dans cette forme de réalisation, un manchon 217 est fixé à l'extrémité de la gaine 207. Ce manchon 217 présente un alésage central dans lequel le câble 7 est positionné libre de tout mouvement axial.In this embodiment, a sleeve 217 is fixed to the end of the sheath 207. This sleeve 217 has a central bore in which the cable 7 is positioned free from any axial movement.

La face externe du manchon comporte une rainure circonférentielle 218 pour son maintien par des pattes élastiques 219 dépendantes de la plaque 109 du boîtier 100 et s'étendant dans la tubulure 110. Lesdites pattes élastiques 219 forment en leur centre un logement cylindrique ouvert 220 pour le positionnement et le maintien du manchon 217.The outer face of the sleeve has a circumferential groove 218 for its retention by elastic tabs 219 dependent on the plate 109 of the housing 100 and extending in the pipe 110. Said elastic tabs 219 form at their center an open cylindrical housing 220 for the positioning and holding the sleeve 217.

Près du bord de ce logement 220, on prévoit un support 202 dans lequel peut être encliqueté l'axe 201 d'un basculeur 272. Ce basculeur porte à chacune de ses extrémités un bouton 203, 204 à faces supérieures bombées. Le bouton 203 est situé au-dessus du logement 220 et présente sur sa face inférieure une chape 205 dans une ouverture de laquelle on introduit l'extrémité recourbée du câble 7.Near the edge of this housing 220, a support 202 is provided in which the axis 201 of a rocker 272 can be snapped in. This rocker carries at each of its ends a button 203, 204 with domed upper faces. The button 203 is located above the housing 220 and has on its underside a yoke 205 in an opening from which the curved end of the cable 7 is introduced.

A la figure 10 le basculeur 272 est dans la position pour laquelle le clapet est fermé, le bouton 203 est en position basse en appui contre la plaque 109. Pour l'ouverture de la bonde, il faut appuyer sur le bouton 204 jusqu'à ce que par rotation du basculeur 272 autour de son axe 201, ledit bouton 204 soit en appui contre la plaque plane 109 ; le bouton 203 est alors en position haute et a tiré sur le câble 7.In FIG. 10 the rocker 272 is in the position for which the valve is closed, the button 203 is in the low position pressing against the plate 109. To open the drain, the button 204 must be pressed until what by rotation of the rocker 272 about its axis 201, said button 204 is pressed against the flat plate 109; the button 203 is then in the high position and has pulled on the cable 7.

Le bouton 204 présente un ergot 206 qui dans la position du basculeur assurant l'ouverture de la bonde est positionné dans un crevé 210 de la plaque 109.The button 204 has a lug 206 which in the position of the rocker ensuring the opening of the plug is positioned in a puncture 210 of the plate 109.

L'ergot 206 est conformé afin de frotter contre les bords du crevé 210 et de favoriser le maintien du basculeur en position d'ouverture du clapet.The lug 206 is shaped in order to rub against the edges of the punctured 210 and to help maintain the rocker in the valve open position.

Le couvercle 108 du boîtier est encliqueté sur la plaque plane 109 par des pattes non représentées, ledit couvercle présente des crevés pour le passage des boutons 203, 204. Sa partie centrale est positionnée au-dessus du (ou des) support 202 pour le maintien du (ou des) axes 201 de basculeurs.The cover 108 of the housing is snapped onto the flat plate 109 by tabs not shown, said cover has punctures for the passage of the buttons 203, 204. Its central part is positioned above the (or) support 202 for the maintenance (or) axes 201 of rockers.

Une membrane souple 240 recouvre le boîtier 100 et dépasse sur sa face inférieure pour maintenir le couvercle 108 et la plaque 109 fermés l'un sur l'autre, et pour assurer une bonne étanchéité.A flexible membrane 240 covers the housing 100 and protrudes on its underside to keep the cover 108 and the plate 109 closed one on the other, and to ensure a good seal.

Une rondelle 241 est prévue autour de l'ouverture 23 de l'appareil sanitaire pour assurer la finition de cette ouverture, cette rondelle est de préférence disposée entre le dessus de l'appareil 24 et la couronne de fixation 101.A washer 241 is provided around the opening 23 of the sanitary appliance to ensure the finishing of this opening, this washer is preferably disposed between the top of the appliance 24 and the fixing ring 101.

La membrane 240 est conformée avec des bourrelets 243, 244 au-dessus des boutons 203, 204. Ces bourrelets portent des indications permettant à l'usager de savoir sur lequel il doit appuyer pour ouvrir ou fermer l'appareil.The membrane 240 is shaped with beads 243, 244 above the buttons 203, 204. These beads bear indications allowing the user to know which one to press to open or close the device.

La membrane 240 présente également un cordon périphérique 245 sous lequel on positionne une bague de finition 250 après l'avoir enfilée autour de l'ensemble qui vient d'être décrit.The membrane 240 also has a peripheral bead 245 under which a finishing ring 250 is positioned after having threaded it around the assembly which has just been described.
