Description

Mécanisme de chasse d'eau pour réservoir de toilettes.Flushing mechanism for toilet tank.
L'invention concerne un mécanisme de chasse d'eau pour réservoir de toilettes (WC) agencé pour permettre l'évacuation, hors du réservoir préalablement rempli, dans une cuvette de WC de deux volumes d'eau différents par action sur au moins un bouton de commande, ledit mécanisme étant entouré par une enveloppe et comprenant un tube de trop-plein muni, à son extrémité inférieure, d'une soupape d'étanchéité coopérant avec un orifice d'évacuation ménagé dans le fond de la cuvette, ledit tube de trop-plein étant agencé pour occuper au moins trois positions axiales, à savoir une position basse de fermeture de l'orifice d'évacuation, une position intermédiaire dite de petite chasse permettant l'évacuation d'un premier volume d'eau et une position supérieure dite de grande chasse permettant l'évacuation d'un second volume d'eau supérieur audit premier volume d'eau, des moyens de commande assurant le déplacement axial du tube de trop-plein depuis sa position basse jusqu'à la position intermédiaire ou la position haute, le mécanisme comprenant en outre un premier flotteur dit de petite chasse monté sur une vis de réglage de hauteur et un second flotteur dit de grande chasse monté pivotant autour d'un axe fixe par rapport à 1 ' enveloppe.The invention relates to a flushing mechanism for a toilet tank (WC) arranged to allow the evacuation, out of the previously filled tank, into a WC bowl of two different volumes of water by action on at least one button. control, said mechanism being surrounded by a casing and comprising an overflow tube provided at its lower end with a sealing valve cooperating with a discharge orifice formed in the bottom of the bowl, said tube being overflow being arranged to occupy at least three axial positions, namely a low position for closing the discharge orifice, an intermediate position called small flush allowing the evacuation of a first volume of water and a position upper so-called large flush allowing the evacuation of a second volume of water greater than said first volume of water, control means ensuring the axial movement of the overflow tube from its low position up to the intermediate position or the high position, the mechanism further comprising a first float called small flush mounted on a height adjustment screw and a second float called large flush mounted pivoting about a fixed axis relative to one envelope.
Afin d'économiser l'eau, qui est coûteuse et précieuse, on a développé, pour des réservoirs de WC, des mécanismes de chasse d'eau permettant l'évacuation, au choix de l'utilisateur, de deux volumes d'eau différents.In order to save water, which is expensive and precious, we have developed flushing mechanisms for WC tanks allowing the evacuation, at the user's choice, of two different volumes of water .
Ces mécanismes «double chasse», comme certains des mécanismes usuels à une seule chasse d'eau comprennent en général un tube de trop-plein mobile en translation verticale à l'intérieur d'une enveloppe, l'extrémité inférieure du tube de trop-plein formant soupape d'étanchéité entre le réservoir et la cuvette du WC. Le déplacement du tube de trop-plein est commandé par au moins un bouton de commande agissant sur une transmission. Deux flotteurs, l'un dit de grande chasse et l'autre dit de petite chasse, déterminent le volume d'eau respectivement évacué lorsque le niveau de 1 ' eau dans le réservoir atteint le flotteur respectif, qui libère le tube de trop-plein, lequel redescend pour fermer la communication entre le réservoir et la cuvette. Le réglage du volume d'eau évacué en petite chasse peut être obtenu par réglage de la position en hauteur du flotteur de petite chasse par rapport au niveau d'eau dans le réservoir.These “double flush” mechanisms, like some of the usual single flush mechanisms, generally include an overflow tube movable in vertical translation inside an envelope, the lower end of the overflow tube. full forming sealing valve between the tank and the toilet bowl. The displacement of the overflow tube is controlled by at least one control button acting on a transmission. Two floats, one called large flush and the other called small flush, determine the volume of water respectively discharged when the level of the water in the tank reaches the respective float, which releases the overflow tube , which descends to close the communication between the tank and the bowl. The adjustment of the volume of water evacuated in small flush can be obtained by adjusting the height position of the small flush float relative to the water level in the tank.
De nombreuses propositions ont été faites pour de tels mécanismes, avec diverses solutions essentiellement pour la transmission entre le ou les boutons de commande et le tube de trop-plein et le mode de coopération entre les flotteurs et le tube de trop-plein. On peut citer, entre autres documents, WO-97/17503, FR-A-2 770 547 ou FR-A-2 720 421. Les solutions connues dans 1 ' état de la technique ne donnent pas totalement satisfaction sur le plan de la sécurité et de la durabilité du fonctionnement, de l'accès pour entretien ou réparation, de la facilité de montage et/ou de réglage, de l'encombrement et/ou du maintien d'une réserve d'eau. De plus, les coûts de ces mécanismes connus sont relativement élevés car ils impliquent de recourir à l'assemblage d'un nombre relativement important de pièces constitutives.Many proposals have been made for such mechanisms, with various solutions essentially for the transmission between the control button (s) and the overflow tube and the mode of cooperation between the floats and the overflow tube. One can cite, among other documents, WO-97/17503, FR-A-2 770 547 or FR-A-2 720 421. The solutions known in one state of the art are not entirely satisfactory in terms of safety and durability of operation, access for maintenance or repair, ease of assembly and / or adjustment, size and / or maintenance of a water reserve. In addition, the costs of these known mechanisms are relatively high because they involve resorting to the assembly of a relatively large number of component parts.
On connaît, par EP-A-0 915 210 (US-A-6 094 753), un mécanisme de chasse d'eau correspondant à l'état de la technique décrit ci-dessus. Ce mécanisme connu présente l'inconvénient d'utiliser une transmission à levier, logée à l'intérieur du tube de trop-plein, donc difficilement accessible et encombrante. En outre, le flotteur de grande chasse est maintenu par un verrouillage mécanique qui est supprimé par action directe du flotteur de petite chasse, ce qui constitue une cause d'usure et un risque de mauvais fonctionnement. De plus, l'ensemble du mécanisme a un encombrement, en particulier en hauteur, important.EP-A-0 915 210 (US-A-6 094 753) discloses a flushing mechanism corresponding to the state of the art described above. This known mechanism has the drawback of using a lever transmission, housed inside the overflow tube, therefore difficult to access and bulky. In addition, the large flush float is held by a mechanical lock which is removed by direct action of the small flush float, which constitutes a cause of wear and a risk of malfunction. In addition, the entire mechanism has a large footprint, in particular in height.
La présente invention vise en conséquence à fournir un nouveau mécanisme double chasse pour réservoir de toilettes qui ne présente pas les inconvénients des mécanismes ci- dessus .The present invention therefore aims to provide a new dual flush mechanism for a toilet tank which does not have the drawbacks of the above mechanisms.
A cet effet, le mécanisme selon l'invention est caractérisé en ce que la vis de réglage est articulée, au voisinage de son extrémité inférieure, sur une extrémité d'un levier dont l'autre extrémité est articulée autour d'un axe fixe par rapport à l'enveloppe, ledit levier est muni d'un ergot coopérant, au cours du déplacement dudit tube de trop-plein de sa position basse à sa position intermédiaire, avec une première came portée par la face extérieure dudit tube de trop-plein et le second flotteur dit de grande chasse est muni d'un ergot coopérant, au cours du déplacement dudit tube de trop-plein entre sa position intermédiaire et sa position haute, avec une seconde came portée par ledit tube de trop- plein et plus éloignée de la soupape d'étanchéité que la première came. Le mécanisme selon l'invention offre l'avantage d'un fonctionnement sûr, même avec un niveau minimal d'eau dans le réservoir. Sa constitution permet de réduire l'encombrement en hauteur du mécanisme et son coût global.To this end, the mechanism according to the invention is characterized in that the adjusting screw is articulated, in the vicinity of its lower end, on one end of a lever whose other end is articulated around a fixed axis by relative to the casing, said lever is provided with a cooperating lug, during the displacement of said overflow tube from its low position to its intermediate position, with a first cam carried by the external face of said overflow tube and the second float, said to be of large flush, is provided with a cooperating lug, during the displacement of said overflow tube between its intermediate position and its high position, with a second cam carried by said overflow tube and more distant of the sealing valve as the first cam. The mechanism according to the invention offers the advantage of safe operation, even with a minimum level of water in the tank. Its constitution reduces the overall height of the mechanism and its overall cost.
De préférence, le tube de trop-plein comporte un épaulement latéral, avec lequel coopère un levier pivotant autour d'un axe orthogonal à la direction de déplacement du tube de trop- plein, ledit levier étant commandé en rotation par un câble sous gaine dont une extrémité est fixée audit levier et l'autre extrémité à un coulisseau commandé selon deux courses différentes par un bouton de commande à deux positions.Preferably, the overflow tube has a lateral shoulder, with which a lever pivots pivoting about an axis orthogonal to the direction of movement of the overflow tube, said lever being controlled in rotation by a sheathed cable, one end is fixed to said lever and the other end to a slide controlled by two different strokes by a control button with two positions.
La transmission par câble sous gaine entre le bouton de commande et le levier pivotant permet une structure simple, économique, fiable et peu encombrante qui autorise en outre un montage du mécanisme de chasse indifféremment avec ou sans fixation du couvercle sur le réservoir.The sheathed cable transmission between the control button and the pivoting lever allows a simple, economical, reliable and space-saving structure which also allows mounting of the flushing mechanism, either with or without fixing the cover to the tank.

Dans l'exemple selon la figure 2, le boîtier 15 est simplement fixé à l'intérieur du réservoir 10 sous la rosace porte-boutons de commande.The tank cover 10 (Figure 1) can be secured to the tank via the flushing mechanism and a rosette 13 control button holder 12 fixed to said cover. In the example according to Figure 2, the housing 1 5 is simply fixed inside the tank 10 under the rosette control button.
Le bouton 12, dont la structure et le fonctionnement seront expliqués plus en détail en référence aux figures 8 à 10, comprend une rosace externe 13 porte-boutons logée dans un orifice du couvercle et vissé, par une saillie filetée 14 (figures 8 à 10) sur un boîtier 15. Une gaine 16 est en butée, à une extrémité, sur le boîtier 15 et, à l'autre extrémité, sur l'enveloppe 2. Un câble de commande 17 (voir figure 7) est logé dans la gaine 16.The button 12, the structure and operation of which will be explained in more detail with reference to FIGS. 8 to 10, comprises an external rosette 13 button holder housed in an opening in the cover and screwed, by a threaded projection 14 (FIGS. 8 to 10 ) on a housing 15. A sheath 16 is in abutment, at one end, on the housing 15 and, at the other end, on the casing 2. A control cable 17 (see FIG. 7) is housed in the sheath 16.
Dans le cas d'une solidarisation du couvercle 11 du réservoir (figure 1), un étrier A est fixé entre le boîtier 15 et le couvercle 11 et ses bras comportent des crans B qui coopèrent chacun avec une attache flexible C solidaire de l'enveloppe 2, de telle sorte que la mise en place du couvercle 11 puisse se faire par simple pression des bras dans lesdites attaches flexibles C. Cette solidarisation sera expliquée plus en détail en référence aux figures 11 à 17.In the case of an attachment of the cover 11 of the reservoir (FIG. 1), a stirrup A is fixed between the housing 15 and the cover 11 and its arms include notches B which each cooperate with a flexible attachment C integral with the envelope 2, so that the fitting of the cover 11 can be done by simple pressure of the arms in the said flexible clips C. This connection will be explained in more detail with reference to FIGS. 11 to 17.
Le tube de trop-plein 1 comporte un épaulement extérieur 20 avec lequel coopère un nez 21 d'un levier 22 pivotant autour d'un axe 23 orthogonal à la direction de translation du tube de trop-plein 1, une extrémité du câble de commande 17 étant fixée au levier 22 de telle sorte qu'une traction sur le câble de commande 17 produise un soulèvement du tube de trop- plein 1.The overflow tube 1 has an external shoulder 20 with which cooperates a nose 21 of a lever 22 pivoting about an axis 23 orthogonal to the direction of translation of the overflow tube 1, one end of the control cable 17 being fixed to the lever 22 so that a pull on the control cable 17 produces a lifting of the overflow tube 1.
Un flotteur de petite chasse 30 est monté sur une vis micrométrique 31 de réglage fin en hauteur qui ajuste la quantité d'eau délivrée. Cette vis comporte une tête de vissage 32 supérieure et son extrémité inférieure est munie d'une rotule 33 d'articulation d'un levier 34 dont l'extrémité opposée à la rotule 33 est articulée autour d'un axe 35 fixe par rapport à l'enveloppe 2. Le levier 34 porte un ergot 36 qui coopère avec une première came 37 portée par le tube de trop-plein 1. La vis de réglage 31 peut avantageusement être en un matériau suffisamment souple pour permettre une mise en place initiale du flotteur de petite chasse 30, muni d'un cran 30' (figure 4), par enfoncement à force sur la vis de réglage 31, le réglage fin de la position en hauteur du flotteur de petite chasse 30 se faisant classiquement par action sur la tête de vis 32.A small flush float 30 is mounted on a micrometric screw 31 for fine height adjustment which adjusts the quantity of water delivered. This screw comprises an upper screwing head 32 and its lower end is provided with a ball 33 of articulation of a lever 34 whose end opposite to the ball 33 is articulated around a axis 35 fixed relative to the casing 2. The lever 34 carries a lug 36 which cooperates with a first cam 37 carried by the overflow tube 1. The adjusting screw 31 can advantageously be made of a material which is sufficiently flexible to allow an initial positioning of the small game float 30, provided with a notch 30 ′ (FIG. 4), by force-pressing on the adjusting screw 31, the fine adjustment of the height position of the small game float 30 is conventionally by acting on the screw head 32.
Un flotteur de grande chasse 40, à pivotement autour d'un axe 41 fixe par rapport a l'enveloppe 2, est monté sur un côté sensiblement diamétralement opposé au flotteur de petite chasse 30 par rapport au tube de trop-plein 1. Le flotteur de grande chasse 40 est muni d'un ergot 42 qui coopère avec une seconde came 43 portée par le tube de trop-plein 1.A large flush float 40, pivoting about an axis 41 fixed relative to the casing 2, is mounted on a side substantially diametrically opposite the small flush float 30 relative to the overflow tube 1. The float big game 40 is provided with a lug 42 which cooperates with a second cam 43 carried by the overflow tube 1.
Le fonctionnement du mécanisme qui vient d'être décrit est le suivant :The operation of the mechanism which has just been described is as follows:
Lorsque le réservoir 10 est plein (figure 3) ou lorsqu'il est vide .{ figure 4), la soupape 3, 4 est en appui sur le siège du culotf 5, de sorte que la communication entre le réservoir 10 et la cuvette est fermée.When the tank 10 is full (Figure 3) or when it is empty. (Figure 4), the valve 3, 4 is supported on the seat of the base f 5, so that the communication between the tank 10 and the bowl is closed.
Une traction en petite chasse sur le câble de commande 17 amène le tube de trop-plein 1 à la position de vidage en petite chasse (figure 5) dans laquelle le flotteur de petite chasse 30 est monté, d'une hauteur déterminée, et la soupape 3, 4 est écartée d'une certaine hauteur du siège du culot 5 et libère le passage entre le réservoir 10 et la cuvette. L'ergot 36 du levier 34 a glissé le long de la première came 37 et est venu se loger sous un épaulement formé par cette came 37. Le flotteur de petite chasse 30 verrouille donc le tube de trop-plein 1 et ne le libère que lorsque le niveau de l'eau dans le réservoir est descendu d'une hauteur telle que le flotteur de petite chasse 30 ne s'appuie plus sur l'eau et redescend, en faisant pivoter le levier 34. L'ergot 36 échappe alors à l'épaulement de la came 37 et le tube de trop-plein 1 retombe brusquement en interrompant le vidage. La quantité d'eau vidée correspond à la petite chasse.A small flush pull on the control cable 17 brings the overflow tube 1 to the small flush emptying position (FIG. 5) in which the small flush float 30 is mounted, of a determined height, and the valve 3, 4 is spaced a certain height from the seat of the base 5 and frees the passage between the reservoir 10 and the bowl. The lug 36 of the lever 34 has slid along the first cam 37 and has come to be housed under a shoulder formed by this cam 37. The small flush float 30 therefore locks the overflow tube 1 and only releases it when the level of the water in the tank has dropped from a height such that the small flush float 30 no longer rests on the water and descends, by pivoting the lever 34. The lug 36 then escapes the shoulder of the cam 37 and the overflow tube 1 suddenly drops, interrupting the emptying. The amount of water emptied corresponds to the small flush.
Une traction sur le câble de commande 17 d'une quantité plus grande amène le tube de trop-plein 1 à une position plus haute de vidage en grande chasse (figure 6). L'ergot 42 du flotteur de grande chasse 40 est venu se loger sous un épaulement de la seconde came 43, de sorte que le flotteur de grande chasse 40 verrouille le tube de trop-plein 1. Comme précédemment, le tube de trop-plein 1 n'est libéré que lorsque le niveau de l'eau dans le réservoir 10 libère le flotteur de grande chasse 40 lequel, en pivotant, écarte l'ergot 42 de la came 43. Le tube de trop plein 1 retombe alors brusquement en position d'obturation, la quantité d'eau vidée correspondant à la grande chasse.A pull on the control cable 17 of a larger amount brings the overflow tube 1 to a higher position for emptying in large flush (Figure 6). The lug 42 of the large flush float 40 is received under a shoulder of the second cam 43, so that the large flush float 40 locks the overflow tube 1. As before, the overflow tube 1 is only released when the water level in the tank 10 releases the high-flush float 40 which, by pivoting, separates the lug 42 from the cam 43. The overflow tube 1 then suddenly drops back into position the quantity of water emptied corresponding to the big game.
La commande de traction du câble 17 selon deux courses différentes peut se faire par divers moyens.The traction control of the cable 17 according to two different strokes can be done by various means.
Selon une forme de réalisation préférée de l'invention représentée aux figures 8 à 10, le bouton 12 comporte deux poussoirs coulissants 50 et 51 rappelés vers l'extérieur du corps 13 par des ressorts 52 et 53 respectivement. Les poussoirs 50 et 51 portent chacun un prolongement axial 54,According to a preferred embodiment of the invention shown in Figures 8 to 10, the button 12 comprises two sliding pushers 50 and 51 returned to the outside of the body 13 by springs 52 and 53 respectively. The pushers 50 and 51 each carry an axial extension 54,
55 coulissant dans la saillie filetée 14, de part et d'autre d'un coulisseau 56 relié à l'extrémité adjacente du câble 17. En position de repos (figure 8), les prolongements .54, 55 sont en appui respectivement sur un appui latéral 57, 58 du coulisseau 56. En enfonçant le poussoir 50 de petite chasse (figure 9), le coulisseau 56 descend sous l'action de la saillie 54 sur l'appui 57, d'une course prédéterminée alors que, lors de l'enfoncement du poussoir 51 de grande chasse (figure 10), le coulisseau 56 descend d'une course supérieure sous l'action de la saillie 55 sur l'appui 58. Le coulisseau55 sliding in the threaded projection 14, on either side of a slide 56 connected to the adjacent end of the cable 17. In the rest position (FIG. 8), the extensions . 54, 55 are supported respectively on a lateral support 57, 58 of the slide 56. By depressing the pusher 50 of small hunting (Figure 9), the slide 56 descends under the action of the projection 54 on the support 57, d 'A predetermined stroke while, when the plunger 51 is pushed in (hunting 10), the slider 56 descends from an upper stroke under the action of the projection 55 on the support 58. The slider
56 est en outre muni de deux saillies latérales 59 coopérant respectivement avec un épaulement 59' des prolongements axiaux 54, 55 pour maintenir le poussoir 50, 51 non actionné.56 is further provided with two lateral projections 59 cooperating respectively with a shoulder 59 'of the axial extensions 54, 55 to keep the pusher 50, 51 not actuated.
Dans l'exemple de' réalisation représenté, l'enveloppe 2 du mécanisme est réalisée en une seule pièce en polypropylène en deux demi-coquilles articulées autour d'une charnière 60 (figure 7) parallèle à l'axe du tube de trop-plein 1. L'enveloppe 2 ouverte permet d'assembler facilement tous les composants à l'intérieur. Sa fermeture assure le positionnement de tous les éléments.In the embodiment shown, the casing 2 of the mechanism is made in one piece of polypropylene in two half-shells articulated around a hinge 60 (Figure 7) parallel to the axis of the overflow tube 1. The open casing 2 makes it easy to assemble all the components inside. Its closure ensures the positioning of all the elements.
En outre, une trappe à glissière 61 est montée à coulissement sur une ouverture latérale 61' ménagée dans la portion de l'enveloppe 2 formant cuve de rétention d'eau de manière à permettre un réglage du niveau résiduel d'eau de 15 à 65 mm dans le bas de 1 ' enveloppe 2 , définissant le retardement à la fermeture de la soupape 3, 4. Par ailleurs, et comme représenté sur les figures 5 et 7, un dégagement 62 ménagé en partie inférieure du tube de trop-plein forme un passage d'écoulement d'eau en position à petite chasse entre le tube de trop-plein 1 et 1 ' enveloppe 2 qui assure une neutralisation de la temporisation lorsque le flotteur de petite chasse 30 est réglé dans le bas de l'enveloppe 2. La hauteur de la cuve de rétention est déterminée par des ouïes 63 ménagées dans l'enveloppe 2, l'ouïe la plus basse déterminant la hauteur de temporisation.In addition, a sliding hatch 61 is slidably mounted on a lateral opening 61 'formed in the portion of the casing 2 forming a water retention tank so as to allow an adjustment of the residual water level from 15 to 65 mm at the bottom of the casing 2, defining the delay in closing the valve 3, 4. Furthermore, and as shown in FIGS. 5 and 7, a clearance 62 formed in the lower part of the overflow tube forms a water flow passage in the small flush position between the overflow tube 1 and the casing 2 which neutralizes the time delay when the small flush float 30 is adjusted at the bottom of the casing 2 The height of the retention tank is determined by louvers 63 formed in the casing 2, the lowest hearing determining the delay height.
Le mécanisme qui vient d'être décrit offre en outre 1 ' avantage de permettre un réglage très bas de la petite chasse, pour un fonctionnement avec un niveau minimal d'eau dans le réservoir (100 mm par exemple). Ce résultat est obtenu par l'indépendance des flotteurs 30 et 40, le flotteur de petite chasse 30 pouvant être descendu en croisant le flotteur de grande chasse 40.The mechanism which has just been described also offers the advantage of allowing very low adjustment of the small flush, for operation with a minimum level of water in the tank (100 mm for example). This result is obtained by the independence of the floats 30 and 40, the small flush float 30 being able to be lowered by crossing the large flush float 40.
Dans l'exemple représenté, le culot 5 est dépourvu de siège en saillie et présente une forme intérieure en tulipe 5 contre laquelle vient porter le rayon de 1 mm situé sur le diamètre extérieur du joint 4 de la tête de soupape 3. L'écoulement d'eau et le débit de chasse sont ainsi améliorés. Par ailleurs, l'effort d'ouverture de la soupape 3 est sensiblement réduit grâce à la diminution de la section de la colonne d'eau qui s'applique sur le joint plat 4.In the example shown, the base 5 does not have a projecting seat and has an internal tulip shape 5 against which comes the radius of 1 mm located on the outside diameter of the seal 4 of the valve head 3. The water flow and the flush rate are thus improved. Furthermore, the opening force of the valve 3 is significantly reduced thanks to the reduction in the section of the water column which is applied to the flat seal 4.
On notera également, que le dispositif qui vient d'être décrit comporte un repère 65 garantissant un niveau d'évacuation minimum de 3 litres imposé par la norme. Ce repère est disposé en partie supérieure du flotteur de petite chasse 30.It will also be noted that the device which has just been described includes a reference 65 guaranteeing a minimum evacuation level of 3 liters imposed by the standard. This mark is arranged in the upper part of the small-game float 30.
On se réfère maintenant aux figures 11 à 17 qui illustrent la solidarisation du couvercle 11 au réservoir par l'intermédiaire du mécanisme de double chasse, tel que représenté a la figure 1. Le but recherché et demandé par les céramistes est d'éviter tout ajustement complexe du mécanisme lors de la fixation du couvercle 11 sur le réservoir 10.Reference is now made to FIGS. 11 to 17 which illustrate the attachment of the cover 11 to the reservoir by means of the double flush mechanism, as shown in FIG. 1. The aim sought and requested by the ceramists is to avoid any adjustment complex mechanism when fixing the cover 11 on the tank 10.
Dans une première phase (figure 11), le couvercle 11 est en appui sur des pattes élastiques 70 que présente la partie supérieure de l'étrier A, prêt à pousser cet étrier A vers le bas. Les crans B les plus bas de l'étrier A sont accrochés aux oreilles à charnière 71 de l'attache flexible C solidaire de 1 ' enveloppe 2. Le boîtier 15 est immobilisé provisoirement par des crans 72 de la tête de l'étrier A.In a first phase (Figure 11), the cover 11 is supported on elastic tabs 70 that has the upper part of the stirrup A, ready to push this stirrup A down. The lowest notches B of the stirrup A are attached to the hinged ears 71 of the flexible clip C secured to the casing 2. The housing 15 is temporarily immobilized by notches 72 of the head of the stirrup A.
Ensuite (voire figure 12), le couvercle 11 est poussé à la main pour venir en appui sur le dessus du réservoir 10. L'étrier A descend et les oreilles à charnière 71 viennent se positionner respectivement sur deux crans B. Le boîtier 15 est immobilisé provisoirement dans l'étrier A par les crans 72.Then (see FIG. 12), the cover 11 is pushed by hand in order to come to rest on the top of the reservoir 10. The stirrup A descends and the hinged ears 71 are positioned respectively on two notches B. The housing 15 is temporarily immobilized in stirrup A by notches 72.
Puis (voir figure 13), la rosace 13 porte-boutons 12 se visse par sa saillie filetée 14 dans un écrou 73 emprisonné dans la tête de l'étrier A. La saillie filetée 14 est terminée par une extrémité conique 74 qui s'engage dans une partie conique creuse 75 correspondante du boîtier 15, lequel est toujours immobilisé dans 'l'étrier A par les crans 72.Then (see Figure 13), the rosette 13 button holder 12 is screwed by its threaded projection 14 in a nut 73 trapped in the head of stirrup A. The threaded projection 14 is terminated by a conical end 74 which engages in a corresponding hollow conical part 75 of the housing 15, which is always immobilized in the stirrup A by the notches 72.
On continue ensuite à visser la rosace 13 dans l' écrou 73 (figure 14), la rosace 13 n'étant pas encore en contact avec le couvercle 11. A la liaison entre la partie conique 74 et le filetage de la saillie filetée 14 de la rosace 13 est ménagée une gorge 76 dans laquelle vient s'engager une saillie circulaire 77 de la partie conique creuse 75 du boîtier 15, de sorte que la rosace 13 devient solidaire du boîtier 15 qui est toujours immobilisé provisoirement dans l'étrier A par les crans 72.Then continues to screw the rosette 13 into the nut 73 (Figure 14), the rosette 13 is not yet in contact with the cover 11. At the connection between the conical part 74 and the thread of the threaded projection 14 of the rosette 13 is formed a groove 76 in which engages a circular projection 77 of the hollow conical part 75 of the housing 15, so that the rosette 13 becomes integral with the housing 15 which is always temporarily immobilized in the stirrup A by the notches 72.
Puis, en continuant à visser la rosace 13 dans l'écrou 73 (figure 15), la rosace 13 entraîne le boîtier 15, lequel se désolidarise de l'étrier A par sortie des crans 72. La rosace 13 vient alors en contact avec le couvercle 11.Then, by continuing to screw the rosette 13 into the nut 73 (FIG. 15), the rosette 13 drives the housing 15, which detaches from the stirrup A by exiting the notches 72. The rosette 13 then comes into contact with the cover 11.
Le vissage de la rosace 13 dans l 'écrou 73 continue (voir figure 16), de sorte que l'étrier A se rapproche du couvercle 11 en écrasant les pattes élastiques 70. Les crans B de l'étrier A s 'accrochant positivement aux oreilles à charnière 71 et le couvercle 11 est ainsi définitivement fixé.The screwing of the rosette 13 in the nut 73 continues (see FIG. 16), so that the stirrup A approaches the cover 11 by crushing the elastic tabs 70. The notches B of the stirrup A positively clinging to the hinged ears 71 and the cover 11 is thus permanently fixed.
Pour le démontage de l'étrier A (figure 17), après dévissage et sortie de la rosace 13 et démontage du couvercle 11, on écarte les oreilles à charnière 71 dont les taquets d'extrémité 78 s'accrochent sur l'enveloppe 2 du mécanisme de chasse d'eau. L'étrier A est ainsi dégagé et peut être remonté ou retiré.For the dismantling of the stirrup A (FIG. 17), after unscrewing and leaving the rosette 13 and dismantling the cover 11, the hinged ears 71 are removed, the end tabs 78 of which hang on the casing 2 of the flushing mechanism. The stirrup A is thus released and can be reassembled or removed.
La solidarisation du couvercle 11 sur le réservoir 10, par l'intermédiaire du mécanisme de chasse d'eau, est donc extrêmement simple et rapide et ne nécessite aucun réglage particulier ni ajustement spécial. The attachment of the cover 11 to the tank 10, by means of the flushing mechanism, is therefore extremely simple and rapid and does not require any particular adjustment or special adjustment.
