Description

L'invention est relative à une chasse d'eau. Elle trouvera notamment son application pour équiper les WC ainsi que les vespasiennes pour animaux.The invention relates to a toilet flush. It will find its application in particular to equip toilets as well as vespasiennes for animals.

On connait de longues dates l'utilisation des chasses d'eau pour assurer le nettoyage des cuvettes de WC, urinoir ou vespasienne. Il s'agit plus particulièrement d'engendrer une trombe d'eau qui de par son débit très important jouit d'un pouvoir de nettoyage puissant.We have known for a long time the use of toilet flushes to ensure the cleaning of toilet bowls, urinals or vespas. This is more particularly to generate a waterspout which by its very large flow has a powerful cleaning power.

Pour ne pas à avoir à surdimensionner les sections des tuyaux d'eau, on utilise une chasse d'eau qui constitue un réservoir alimenté depuis le réseau de distribution urbain d'eau à faible débit, qui est pourvu d'une canalisation d'evacuation d'eau vers la cuvette susceptible d'acheminer un débit momentané important.In order not to have to oversize the sections of the water pipes, a flush is used which constitutes a reservoir supplied from the urban low-flow water distribution network, which is provided with an evacuation pipe. of water to the bowl likely to carry a large momentary flow.

En outre, le volume de la chasse d'eau permet de quantifier le nombre de litres d'eau utilisés à chaque manoeuvre.In addition, the volume of the toilet flush quantifies the number of liters of water used for each maneuver.

Actuellement, les chasses d'eau sont munies d'un dispositif de remplissage à robinet commandé par un flotteur qui ferme le robinet lorsque le niveau d'eau à l'intérieur de la cuve a atteint une valeur pré-fixée. Par ailleurs, une cage de manoeuvre permet d assurer l'ouverture d'un clapet disposé au fond de la cuve et qui autorise l'écoulement du contenu de la cuve par une conduite alimentant directement la cuvette. Ce dispositif d'obturation appelé tampon comprend outre le clapet, un flotteur relié à ce dernier qui maintient l'ouverture de ce dernier durant toute la phase d'évacuation de l'eau contenue dans la cuve.Currently, toilet flushes are fitted with a tap filling device controlled by a float which closes the tap when the water level inside the tank has reached a pre-set value. Furthermore, an operating cage makes it possible to ensure the opening of a valve disposed at the bottom of the tank and which allows the flow of the contents of the tank through a pipe directly supplying the bowl. This closure device called buffer comprises, in addition to the valve, a float connected to the latter which maintains the opening of the latter during the entire phase of evacuation of the water contained in the tank.

Les chasses d'eau actuelles comme GB-A-205 342 sont bien adaptées pour des usages domestiques mais souffrent d'inconvénients importants lorsqu'elles doivent être utilisées dans des lieux publics ou lorsqu'il s'agit de les incorporer dans des dispositifs automatiques pour par exemple constituer des vespasiennes pour animaux.Current flushers like GB-A-205 342 are well suited for domestic uses but suffer from significant disadvantages when they are to be used in public places or when it is a question of incorporating them into automatic devices. to for example constitute vespasiennes for animals.

En effet, la manoeuvre des chasses d'eau actuelles exige une intervention extérieure pour assurer leur fonctionnement. Si les différents utilisateurs des WC omettent de faire fonctionner la chasse d'eau, l'endroit devient très rapidement insalubre. Il est par conséquent très souhaitable de constituer des dispositifs automatiques qui interviennent de même sans qu'un opérateur n'ait à exercer une action extérieure.Indeed, the maneuvering of current flushes requires external intervention to ensure their operation. If the different toilet users fail to operate the toilet, the place quickly becomes unsanitary. It is therefore very desirable to constitute automatic devices which intervene in the same way without an operator having to exert an external action.

Ainsi, des dispositifs utilisant par exemple des cellules photo-électriques pour détecter une présence sont utilisés pour automatiser le nettoyage des WC. On peut cependant regretter que ces dispositifs automatiques fassent appel à un ensemble électronique auxiliaire qui grèvent considérablement le coût des installations, qui en outre associent eau-électricité, ce qui présente des dangers et enfin qui de par leur complexité sont sujets à des pannes.Thus, devices using for example photoelectric cells to detect a presence are used to automate the cleaning of toilets. It is however regrettable that these automatic devices make use of an auxiliary electronic assembly which considerably increases the cost of the installations, which moreover combine water-electricity, which presents dangers and finally which, due to their complexity, are subject to breakdowns.

Par ailleurs, pour des applications telles que vespasiennes pour animaux qui verraient le jour en ville pour éviter que les animaux domestiques ne salissent les rues, l'utilisation de dispositifs électroniques sophistiqués serait difficile à mettre en oeuvre étant donné la diversité des gabarits d'animaux susceptibles d'être rencontrés. Par exemple, les cellules photo-électriques seraient placées tantôt trop hautes pour les chats, tantôt trop basses pour les grands chiens.Furthermore, for applications such as vespasiennes for animals which would emerge in town to prevent domestic animals from dirtying the streets, the use of sophisticated electronic devices would be difficult to implement given the diversity of animal sizes likely to be encountered. For example, the photocells would be placed sometimes too high for cats, sometimes too low for large dogs.

Il faut également souligner que les dispositifs électroniques actuellement existants sont adaptés au cas des urinoirs où ils assurent un écoulement continu de l'eau de nettoyage, mais ne sont pas utilisés pour des WC de type à cuvette classique.It should also be emphasized that the currently existing electronic devices are suitable for urinals where they provide a continuous flow of cleaning water, but are not used for toilets of the conventional bowl type.

Le but principal de la présente invention est de présenter une chasse d'eau dont le fonctionnement est entièrement automatique, Ainsi, la chasse d'eau de la présente invention pourra parfaitement être utilisée dans les WC de lieux publics ainsi que les vespasiennes pour animaux quel que soit le type de cuvettes à nettoyer.The main purpose of the present invention is to present a flush, the operation of which is fully automatic. whatever the type of bowl to be cleaned.

Son fonctionnement est de type classique c'est-à-dire que la chasse d'eau est susceptible d'engendrer un fort débit d'eau momentané dont le pouvoir de nettoyage est très élevé, surtout s'il est hydropneumatique.Its operation is of the conventional type, that is to say that the flush is capable of generating a high momentary flow of water whose cleaning power is very high, especially if it is hydropneumatic.

La quantité d'eau délivré par la chasse d'eau de la présente invention est pré-réglée ce qui évite tout gaspillage.The amount of water delivered by the flush of the present invention is preset which avoids any waste.

Par ailleurs, l'automatisme du fonctionnement de la présente invention ne fait pas appel à des techniques électroniques ou électriques sophistiquées ce qui facilite la mise en place et limite son coût. De plus, le mécanisme est particulièrement robuste ce qui pré-destine plus particulièrement l'invention à une utilisation intensive.Furthermore, the automatic operation of the present invention does not use sophisticated electronic or electrical techniques which facilitates installation and limits its cost. In addition, the mechanism is particularly robust which more particularly pre-destines the invention for intensive use.

D'autres buts et avantages de la présente invention apparaitront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

La chasse d'eau qui trouvera son application notamment dans les WC ainsi que les vespasiennes pour animaux destinée à approvisionner certaines quantités d'eau une cuvette par une commande extérieure et alimentée à partir d'un réseau de distribution d'eau est caractérisée par le fait qu'elle se compose:

The flush which will find its application in particular in the WC as well as the vespasiennes for animals intended to supply certain quantities of water a basin by an external control and supplied from a water distribution network is characterized by the fact that it consists of:
  • - at least two tanks,
  • - means for transferring the content of the upstream tank (s) into the downstream tank (s),

On sait que l'efficacité d'une chasse d'eau est non seulement liée à la quantité d'eau qu'elle est susceptible de délivrer mais également à son débit. A cet égard, la chasse d'eau de la présente invention répond parfaitement aux exigences, ceci malgré l'utilisation d'un réseau de distribution d'eau de faible section.We know that the efficiency of a flush is not only linked to the quantity of water that it is capable of delivering but also to its flow. In this regard, the flush of the present invention perfectly meets the requirements, despite the use of a small section water distribution network.

La figure 1 schématise les différentes pièces composant la chasse d'eau 1 de la présente invention, celle-ci comprend au moins deux cuves 2 et 3, ainsi que des moyens de transfert 4 du contenu de la ou des cuves 2 amont dans la ou les cuves aval 3.Figure 1 shows schematically the different parts composing the flush 1 of the present invention, it comprises at least two tanks 2 and 3, as well as means 4 for transferring the content of the tank (s) 2 upstream in the or the downstream tanks 3.

En outre, la chasse d'eau 1 de la présente invention comprend des moyens de remplissage 5 de la ou les cuves amont 2 à partir du réseau de distribution d'eau 6.In addition, the flush 1 of the present invention comprises means 5 for filling the upstream tank (s) 2 from the water distribution network 6.

La chasse d'eau 1 comprend également des moyens d'évacuation 7 du contenu de la ou des cuves aval 3 vers la cuvette à nettoyer non illustrée.The flush 1 also includes means 7 for evacuating the content of the downstream tank (s) 3 to the bowl to be cleaned, not shown.

Les différents organes qui constituent les moyens de transfert 4, de remplissage 5 et d'évacuation 7 sont commandés c'est-à-dire que la manoeuvre de leur ouverture, ou de leur fermeture est pilotée extérieurement.The various members which constitute the transfer 4, filling 5 and evacuation 7 means are controlled, that is to say that the operation of their opening, or of their closing, is controlled externally.

De préférence, la chasse d'eau 1 se compose d'une cuve amont 2 supérieure et d'une cuve aval inférieure 3. Leur différence d'altitude fait que le transvasement du contenu de la cuve supérieure dans la cuve inférieure peut très facilement être réalisé par simple ouverture des moyens de transfert 4.Preferably, the flush 1 consists of an upper upstream tank 2 and a lower downstream tank 3. Their difference in altitude means that the content of the contents of the upper tank can be transferred to the lower tank very easily. produced by simply opening the transfer means 4.

Selon le principe de fonctionnement du dispositif de commande le la présente invention, celui-ci actionne dans un premier temps les moyens de transfert 4 du contenu de la cuve amont 2 dans la cuve aval 3, puis dans un deuxième temps actionne les moyens de remplissage 5 de la cuve amont 2 et les moyens d'évacuation 7 de la cuve aval.According to the operating principle of the control device of the present invention, it actuates firstly the means 4 for transferring the contents of the upstream tank 2 into the downstream tank 3, then in a second time actuates the filling means 5 from the upstream tank 2 and the discharge means 7 from the downstream tank.

Les différentes phases du fonctionnement du dispositif de commande sont illustrées aux figures 2a à 2d.The different phases of the operation of the control device are illustrated in Figures 2a to 2d.

A la figure 2a, on peut observer la chasse d'eau en position de repos dans laquelle la cuve supérieure 2 est remplie d'eau alors que la cuve inférieure 3 est vide. Les moyens de transfert 4, de remplissage 5 et d'évacuation 7 sont alors obturés.In Figure 2a, we can observe the flush in the rest position in which the upper tank 2 is filled with water while the lower tank 3 is empty. The transfer means 4, filling 5 and evacuation 7 are then closed.

Lorsque le dispositif de commande est actionné tel qu'illustré à la figure 2b, les moyens de transfert 4 sont manoeuvrés ce qui a pour conséquence de vider le contenu de la cuve amont 2 dans la cuve aval 3.When the control device is actuated as illustrated in FIG. 2b, the transfer means 4 are maneuvered, which results in emptying the contents of the upstream tank 2 into the downstream tank 3.

A ce stade, les moyens de remplissge 5 et d'évacuation 7 sont toujours obturés.At this stage, the filling 5 and discharge 7 means are always closed.

La figure 2c illustre la fin de la phase préparatoire au fonctionnement de la chasse d'eau c'est-à-dire lorsque l'intégralité du contenu de la cuve amont 2 s'est déversé dans la cuve aval 3.FIG. 2c illustrates the end of the preparatory phase for the operation of the flush, that is to say when the entire content of the upstream tank 2 has poured into the downstream tank 3.

La phase du déclenchement de la chasse d'eau est illustrée à la figure 2d dans laquelle les moyens d'évacuation 7 s'ouvrent ce qui a pour conséquence de vider le contenu de la cuve aval 3 en direction de la cuvette par l'intermédiaire de la conduite 8 située dans le prolongement des moyens d'évacuation 7. Parallèlement, les moyens de transfert 4 sont obturés et les moyens de remplissage 5 ouverts ce qui permet à la cuve amont 2 de se remplir à partir du réseau de distribution d'eau 6 jusqu'à un niveau prédéterminé.The phase of triggering the flush is illustrated in FIG. 2d in which the discharge means 7 open, which has the consequence of emptying the content of the downstream tank 3 in the direction of the bowl via of the pipe 8 located in the extension of the discharge means 7. At the same time, the transfer means 4 are closed and the filling means 5 open which allows the upstream tank 2 to be filled from the distribution network of water 6 to a predetermined level.

A l'issue de ces étapes, on se retrouve au niveau de la phase de repos telle qu'illustrée à la figure 2a.At the end of these steps, we find ourselves at the rest phase as illustrated in FIG. 2a.

Selon l'automatisme du dispositif de commande équipant la chasse d'eau de la présente invention, les deux phases principales du fonctionnement de la chasse d'eau sont d'une part commandées lorsqu'un occupant s'introduit dans le local de la cuvette, il s'agit de la phase 2b, c'est-à-dire le remplissage de la cuve aval à partir de la cuve amont puis la phase de nettoyage illustrée à la figure 2d qui survient lorsque l'occupant quitte les lieux, ce qui permet d'assurer un nettoyage de la cuvette avant qu'un prochain utilisateur ne vienne.According to the automation of the control device equipping the toilet flush of the present invention, the two main phases of the operation of the toilet flush are on the one hand controlled when an occupant enters the room of the bowl , this is phase 2b, i.e. filling the downstream tank from the upstream tank and then the cleaning phase illustrated in Figure 2d which occurs when the occupant leaves the premises, which ensures cleaning of the bowl before a next user comes.

Les figures 3 et 4 illustrent respectivement en vue de coupe la face avant et deux côtés d'un mode préférentiel de réalisation de la chasse d'eau 1 de la présente invention.Figures 3 and 4 illustrate respectively in sectional view the front face and two sides of a preferred embodiment of the flush 1 of the present invention.

La chasse d'eau se compose d'une cuve supérieure 2 et d'une cuve inférieure 3 qui sont superposées. Cette réalisation monobloc est particulièrement intéressante au niveau de la fabrication puisque le fond 9 de la cuve supérieure 2 fait office de couvercle pour la cuve inférieure 3. La cuve supérieure 2 est elle-même fermée par un couvercle 10.The flush consists of an upper tank 2 and a lower tank 3 which are superimposed. This monobloc embodiment is particularly advantageous at the manufacturing level since the bottom 9 of the upper tank 2 acts as a cover for the lower tank 3. The upper tank 2 is itself closed by a cover 10.

La cuve supérieure 2 présente une conduite 6 de raccordement au réseau de distribution d'eau. Alors que la cuve inférieure 3 présente dans sa partie inférieure une canalisation 8 qui la relie à la cuvette du WC à nettoyer ou autre.The upper tank 2 has a pipe 6 for connection to the water distribution network. While the lower tank 3 has in its lower part a pipe 8 which connects it to the toilet bowl to be cleaned or the like.

Des moyens de transfert 4 du contenu de la cuve supérieure 2 dans la cuve inférieure 3 se présentent sous la forme d'un tampon composé d'un clapet 10 d'obturation solidaire d'un flotteur 11 et d'une conduite 12 reliant les volumes intérieurs des deux cuves 2 et 3.Means 4 for transferring the contents of the upper tank 2 into the lower tank 3 are in the form of a buffer composed of a shutter valve 10 secured to a float 11 and a pipe 12 connecting the interior volumes of the two tanks 2 and 3.

Le clapet d'obturation 10 a son siège 13 fixé sur le fond 9 de la cuve 2. Le clapet 10 est surmonté d'une tige de manoeuvre 14 qui lui permet d'être actionné.The shutter valve 10 has its seat 13 fixed on the bottom 9 of the tank 2. The valve 10 is surmounted by an operating rod 14 which allows it to be actuated.

Le rôle classique du flotteur 11 est de maintenir le clapet 10 dégagé de son siège 13 tant que le volume d'eau présent dans la cuve amont 2 n'a pas été totalement transvasé dans la cuve aval 3. En position fermée, la pression de la colonne d'eau s'exerçant sur la surface supérieure du clapet est plus forte que la poussée exercée par le flotteur ne peut donc jouer un rôle que lorsque le clapet a été dégagé de son siège sous une action extérieure, transmise par l'intermédiaire de la tige de commande 14.The conventional role of the float 11 is to keep the valve 10 clear of its seat 13 as long as the volume of water present in the upstream tank 2 has not been completely transferred into the downstream tank 3. In the closed position, the pressure of the water column acting on the upper surface of the valve is stronger than the thrust exerted by the float can therefore only play a role when the valve has been released from its seat under an external action, transmitted through of the control rod 14.

Les moyens d évacuation 7 du contenu de la cuve aval 3 se présentent sous une forme sensiblement identique à celle des moyens de transfert 4. Les moyens d'évacuation 7 se composent d'un tampon qui comprend un clapet 14 d'obturation de la canalisation 8 d'évacuation du liquide vers la cuvette. Le clapet d'obturation 14 voit son siège 15 fixé sur le fond de la cuve 3 et le clapet est doté d'une tige supérieure de commande 16.The means of evacuation 7 of the contents of the downstream tank 3 are in a form substantially identical to that of the transfer means 4. The evacuation means 7 consist of a buffer which comprises a valve 14 for closing the pipe 8 evacuation of the liquid to the bowl. The shutter valve 14 has its seat 15 fixed to the bottom of the tank 3 and the valve has an upper control rod 16.

Les moyens de remplissage 5 sont formés d'un robinet 17 commandé par un flotteur 18 placé dans la cuve amont 2. Ce dispositif fonctionne selon la hauteur d'eau présente dans la cuve amont 2. Au fur et à mesure que le niveau d'eau monte dans la dite cuve 2, le flotteur 18 voit sa hauteur progresser et ce déplacement est susceptible de provoquer l'obturation du robinet 17 lorsqu'un certain niveau d'eau a été atteint.The filling means 5 are formed by a tap 17 controlled by a float 18 placed in the upstream tank 2. This device operates according to the height of water present in the upstream tank 2. As the level of water rises in said tank 2, the float 18 sees its height progress and this movement is likely to cause the valve 17 to be closed when a certain level of water has been reached.

Selon l'invention, la tige de commande 14 du clapet 10 est prolongée par une tige 19 de soutien du flotteur 18 du robinet 17 de remplissage. Cette disposition fait que toute manoeuvre ascendante donc d'ouverture du clapet 10 provoque parallèlement une élévation du flotteur 18 et donc une fermeture du robinet d'amenée d'eau 17.According to the invention, the control rod 14 of the valve 10 is extended by a rod 19 for supporting the float 18 of the filling valve 17. This arrangement means that any ascending operation, therefore opening of the valve 10, causes in parallel an elevation of the float 18 and therefore a closing of the water supply tap 17.

Ainsi, l'une des caractéristiques de fonctionnement de la chasse automatique de la présente invention est respectée c'est-à-dire que l'ouverture des moyens de transfert du contenu de la cuve amont vers la cuve aval bloque le remplissage de la cuve amont.Thus, one of the operating characteristics of the automatic flush of the present invention is respected, that is to say that the opening of the means for transferring the contents of the upstream tank to the downstream tank blocks the filling of the tank. upstream.

Un mode de réalisation du dispositif de commande 20 est illustré aux figures 3 et 4. Ce dispositif de commande se présente sous la forme d'une tringlerie 20 composée d'un premier levier 21 articulé au niveau de sa partie médiane 22, et qui comprend à l'une de ses extrémités l'accrochage d'une tige de commande 23 et à l'autre extrémité un système de liaison 24 au clapet 10 de transfert du contenu de la cuve amont 2 dans la cuve aval 3. La tige de commande est entouré d'un tube 25 traversant le fond de la cuve inférieure 3 et étanche afin qu'aucune fuite de liquide mais surtout d'air ne puisse être déplorée au niveau du passage de la tige de commande. Toute traction sur la tige de commande 23 a pour conséquence de faire basculer le premier levier 21 qui ainsi soulève le clapet 10 pour vider le contenu de la cuve 2 dans la cuve 3 et empêcher le remplissage de la cuve 2 par fermeture du robinet 17.An embodiment of the control device 20 is illustrated in FIGS. 3 and 4. This control device is in the form of a linkage 20 composed of a first lever 21 articulated at its median part 22, and which comprises at one of its ends the attachment of a control rod 23 and at the other end a connection system 24 to the valve 10 for transferring the content of the upstream tank 2 into the downstream tank 3. The control rod is surrounded by a tube 25 passing through the bottom of the lower tank 3 and sealed so that no leakage of liquid but especially of air can be deplored at the passage of the control rod. Any traction on the control rod 23 has the consequence of tilting the first lever 21 which thus raises the valve 10 to empty the contents of the tank 2 in the tank 3 and prevent filling of the tank 2 by closing the tap 17.

Le dispositif de commande 20 comprend un second levier 26 articulé dans sa partie médiane 27 et qui comprend à l'une de ses extrémités un raccord articulé 28 avec l'extrémité du premier levier 21 et à l'autre extrémité est relié à la tige 16 de manoeuvre du clapet 14 d'évacuation du contenu de la cuve 3 vers la cuvette.The control device 20 comprises a second lever 26 articulated in its central part 27 and which comprises at one of its ends an articulated connection 28 with the end of the first lever 21 and at the other end is connected to the rod 16 for operating the valve 14 for discharging the contents of the tank 3 towards the bowl.

Le mécanisme décrit fonctionne de la manière suivante, lorsque la tige de commande 23 est tirée vers le bas, elle provoque l'ouverture du clapet 10 de transfert du contenu de la cuve 2 dans la cuve 3 et la fermeture du robinet 17 ainsi que par basculement du second levier 26 la fermeture du clapet 14 qui vient s'appliquer contre son siège 15. On assiste ainsi à la phase de transfert du contenu des cuves avec blocage des moyens de remplissage et d'évacuation.The mechanism described operates in the following manner, when the control rod 23 is pulled down, it causes the opening of the valve 10 for transferring the contents of the tank 2 into the tank 3 and the closing of the tap 17 as well as by tilting of the second lever 26 closing of the valve 14 which is applied against its seat 15. We thus witness the phase of transfer of the contents of the tanks with blocking of the filling and evacuation means.

Puis, lorsque la tige de commande 23 est relâchée, le clapet 10 retombe sur son siège 13, cette manoeuvre peut par exemple être facilitée par l'adjonction d'un poids 29 sur la tige 19. Le mouvement ascendant de cette tige permet au flotteur 18 de redescendre car il n'est soutenu par aucun fluide ce qui a pour conséquence l'ouverture du robinet 17 et donc le remplissage de la cuve 2 jusqu'à ce que le niveau d'eau fasse remonter le flotteur 18 jusqu'à fermer le robinet 17.Then, when the control rod 23 is released, the valve 10 falls back onto its seat 13, this maneuver can for example be facilitated by the addition of a weight 29 on the rod 19. The upward movement of this rod allows the float 18 to descend again because it is not supported by any fluid which results in the opening of the tap 17 and therefore the filling of the tank 2 until the water level causes the float 18 to rise up until it closes the tap 17.

Par ailleurs, le relâchement de la tige 23 de commande fait également basculer le second levier 26 qui exerce une traction au niveau du clapet 14 d'évacuation d'eau qui permet d'alimenter la cuvette au-travers de la canalisation 8, ceci jusqu'à vider intégralement la cuve 3.Furthermore, the release of the control rod 23 also causes the second lever 26 to tilt, which exerts a traction at the level of the water evacuation valve 14 which makes it possible to supply the bowl through the pipe 8, this up to '' to completely empty the tank 3.

Les différentes phases du fonctionnement automatique de la chasse d'eau peuvent donc être exécutées par le dispositif de commande décrit.The different phases of the automatic flushing operation can therefore be carried out by the control device described.

La figure 5 illustre l'une des conceptions possibles pour exercer l'action sur la tige de commande 23 de la chasse d'eau 1 sans intervention volontaire d'un opérateur. Pour cela, une partie du sol 30 est formée d'une plaque 31 articulée à l'une de ses extrémités 32 et qui présente à son autre extrémité une liaison 33 avec la tige de commande 23. En outre, des moyens élastiques 34 sont disposés sous la plaque 31 de sorte à exercer un rappel de la plaque, la masselotte 9 doit être suffisante.FIG. 5 illustrates one of the possible designs for exerting the action on the control rod 23 of the flush 1 without the voluntary intervention of an operator. For this, a part of the ground 30 is formed of a plate 31 articulated at one of its ends 32 and which has at its other end a connection 33 with the control rod 23. In addition, elastic means 34 are arranged under the plate 31 so as to exert a reminder of the plate, the counterweight 9 must be sufficient.

Lorsqu'un utilisateur s'introduit dans les lieux, de par son poids, il appuie sur la plaque 31 qui pivote autour de l'axe 32 et s'abaisse au niveau de son extrémité pour exercer une traction sur la liaison 33 qui répercute son déplacement sur la tige de commande 23 provoquant ainsi la première phase du fonctionnement en automatique c'est-à-dire le transfert du contenu de la cuve amont dans la cuve aval.When a user enters the premises, by its weight, it presses on the plate 31 which pivots around the axis 32 and lowers at its end to exert traction on the link 33 which reflects its displacement on the control rod 23 thus causing the first phase of automatic operation, that is to say the transfer of the contents of the upstream tank into the downstream tank.

Au contraire, lorsque l'utilisateur quitte les lieux, il n'exerce plus son poids sur la plaque 31 qui grâce aux moyens élastiques de rappel 34 revient en position et autorise une remontée de la tige de commande 23 qui par cette manoeuvre provoque la phase de remplissage de la cuve amont et la vidange de la cuve aval dans la cuvette.On the contrary, when the user leaves the premises, he no longer exerts his weight on the plate 31 which thanks to the elastic return means 34 returns to position and authorizes a rise in the control rod 23 which by this maneuver causes the filling phase of the upstream tank and the emptying of the downstream tank in the bowl.

Pour les vespasiennes pour animaux, l'ouverture de la cuve aval 2 peut être retardée par l'adjonction par exemple d'un système genre "groom de porte", afin que l'animal ait le temps de s'éloigner et ne se fasse pas arroser les pattes.For vespasiennes for animals, the opening of the downstream tank 2 can be delayed by adding, for example, a "door bellman" system, so that the animal has time to move away and does not happen not water the legs.

Dans un mode de réalisation pneumatique, la cuve (1) peut se déverser "sous pression" dans la cuve 2. De même, la cuve 2 se déverse sous pression dans la cuvette. Lors du remplissage de chaque cuve, l'air est emprisonné et se trouve comprimé dans le haut de chaque cuve. C'est le rôle des clapets 35, ainsi que la conception des trop-pleins sous forme de vases communiquants. Ceux-ci assurent une "prise d'air" lorsque les cuves sont vides, mais la bloquent au remplissage.In a pneumatic embodiment, the tank (1) can pour "under pressure" into the tank 2. Likewise, the tank 2 pours under pressure into the bowl. When filling each tank, the air is trapped and is compressed at the top of each tank. This is the role of the valves 35, as well as the design of the overflows in the form of communicating vessels. These provide an "air intake" when the tanks are empty, but block it from filling.

Il y a deux modèles, un modèle ordinaire et un pneumatique réservé surtout aux animaux:There are two models, an ordinary model and a tire reserved mainly for animals:

Occupation : air emprisonné et comprimé

  • - tube 25 obturé
  • - godet 36 empêchant l'air de passer
  • - tube 37 obturé
  • - trop plein se remplit et empêche l'air de passer
Occupation: trapped and compressed air
  • - closed tube 25
  • - bucket 36 preventing air from passing
  • - tube 37 closed
  • - too full fills and prevents air from passing

Local libre - position de repos : air emprisonné et comprimé

  • - clapet 10 obturé
  • - tube 37 obturé
  • - trop plein se remplit et empêche l'air de passer.
Free room - rest position: trapped and compressed air
  • - valve 10 closed
  • - tube 37 closed
  • - too full fills and prevents air from passing.

Dans un mode de réalisation particulier de l'invention, illustré par les figures 6, 7 et 8, la chasse d'eau comporte deux cuves amont 2a et 2b, dont les leviers de manoeuvre 37 et 38 des clapets de transfert 10a et 10b sont actionnés par un basculeur 39, monté articulé par rapport à un cadre fixe 40, délimitant le débattement d'un doigt 41 solidaire d'une tige coulissante 42 commandant le clapet d'obturation 7 de la cuve aval 3.In a particular embodiment of the invention, illustrated by FIGS. 6, 7 and 8, the flush includes two upstream tanks 2a and 2b, the operating levers 37 and 38 of the transfer valves 10a and 10b are actuated by a rocker 39, mounted articulated with respect to a fixed frame 40, delimiting the movement of a finger 41 secured to a sliding rod 42 controlling the shutter valve 7 of the downstream tank 3.

Ainsi, dans ce mode de réalisation, l'action du plancher 31, représenté à la figure 5, peut être remplacé par celle d'un électro-aimant ou d'un vérin, dont la mise en fonction est commandée, par exemple, par la manoeuvre du verrou de la porte d'accès ou de cette porte elle-même, assurant la fermeture de la cuve aval 3 par coulissement vers le bas, de la tige 42, jusqu'à mise en contact du doigt 41 contre le basculeur 39 et pivotement de celui-ci. Cette manoeuvre a pour effet d'assurer l'obturation de la cuve aval 3 et de libérer l'eau contenue dans l'une des cuves amont, par soulèvement du clapet correspondant par l'intermédiaire du levier reliant la tige de celui-ci à l'un des bras du basculeur. Lors de la réouverture de la porte, l'action de l'électro-aimant ou du vérin cesse et la tige de commande 4c est alors rappelée vers le haut sous l'effet du contre-poids 43 monté sur l'une des branches des leviers de manoeuvre 44 et 45 de la tige de commande 42. Ceci a pour effet de soulever le clapet d'obturation 7 de la cuve aval 3 et de mettre celle-ci en écoulement et d'assurer l'obturation de la cuve amont précédemment mise en vidange, tout en commandant le remplissage de celle-ci.Thus, in this embodiment, the action of the floor 31, shown in FIG. 5, can be replaced by that of an electromagnet or of a jack, the activation of which is controlled, for example, by the operation of the lock of the access door or of this door itself, ensuring the closing of the downstream tank 3 by sliding downwards, of the rod 42, until the finger 41 comes into contact with the rocker 39 and pivoting thereof. This maneuver has the effect of closing off the downstream tank 3 and releasing the water contained in one of the upstream tanks, by lifting the corresponding valve by means of the lever connecting the rod thereof to one of the rocker arms. When the door reopens, the action of the electromagnet or the cylinder ceases and the control rod 4c is then raised upwards under the effect of the counterweight 43 mounted on one of the branches of the operating levers 44 and 45 of the control rod 42. This has the effect of raising the shutter valve 7 of the downstream tank 3 and putting the latter in flow and ensuring the shutting off of the upstream tank emptying, while controlling the filling thereof.

En examinant plus particulièrement les figures 7 et 8, on remarque que le basculeur 39 est articulé par rapport à un axe 46 fixé entre la base du cadre fixe 40 et une équerre 40a solidaire de ce dernier. Le basculeur 39 est rappelé en position neutre par l'intermédiaire d'un ressort 47 prenant appui contre la base de l'équerre 40a, et d'un ergot 48 disposé à la base du basculeur 39, dans l'axe de symétrie de celui-ci.By examining more particularly FIGS. 7 and 8, it can be seen that the rocker 39 is articulated with respect to an axis 46 fixed between the base of the fixed frame 40 and a bracket 40a secured to the latter. The rocker 39 is returned to the neutral position by means of a spring 47 bearing against the base of the bracket 40a, and a lug 48 disposed at the base of the rocker 39, in the axis of symmetry of that -this.

Dans ce mode de réalisation, il n'est plus nécessaire d'attendre que la cuve amont se remplisse et de maintenir la porte fermée pendant le temps du remplissage, puisque la cuve amont est doublée et que chacune des cuves est autonome. Il y a donc ainsi toujours une cuve pleine en réserve et deux utilisations successives sont possibles.In this embodiment, it is no longer necessary to wait for the upstream tank to fill and to keep the door closed during the filling time, since the upstream tank is doubled and each of the tanks is autonomous. There is therefore always a full tank in reserve and two successive uses are possible.
