Abstract

The cistern (1) has an outlet (3), a stopper (4) and a mechanism to control the stopper. It also has a means of interrupting the flow once the control knob (6) is released, consisting of a weight (8) which increases the weight of the stopper. The weight forms part of a piston (12) which travels along a cylindrical chamber (14); the upper part of the chamber exerts a certain friction force on the piston, while the lower one exerts no friction, since it has a broader section from mid-height. The weight, connected to the stopper and located on the end of a rod (7), counteracts any buoyancy in the piston and accelerates the closure of the stopper once the control knob is released. <IMAGE>

Description

La présente invention est relative à un système de dosage d'eau de vidange d'un réservoir de chasse d'eau pourvu d'un orifice d'écoulement, un bouchon d'obturation et un mécanisme de commande du bouchon d'obturation.The present invention relates to a system for dosing the drain water of a flush tank provided with a drainage orifice, a closure plug and a control mechanism for the closure plug.

Elle concerne plus particulièrement un perfectionnement à un dispositif de vidange d'une toilette ou W.-C. en vue de limiter la consommation d'eau. Elle est destinée à réduire la quantité d'eau consommée et de l'adapter aux besoins. Il est en effet connu que les dispositifs des toilettes et W.-C.'s consomment une quantité appréciable d'eau.It relates more particularly to an improvement to a device for emptying a toilet or WC in order to limit the consumption of water. It is intended to reduce the amount of water consumed and to adapt it to needs. It is indeed known that toilets and toilets devices consume an appreciable quantity of water.

De tels dispositifs de vidange sont souvent utilisés à pleine capacité, alors qu'une quantité bien plus faible s'avère suffisante.Such emptying devices are often used at full capacity, while a much smaller amount is sufficient.

On a pu calculer qu'on peut épargner annuellement par personne jusqu'à 100 hectolitres d'eau en évitant le gaspillage d'eau lors des vidanges.We have been able to calculate that we can save annually per person up to 100 hectoliters of water by avoiding wasting water during emptying.

On connaît par le brevet belge n° 877.662 un système de réservoir de chasse d'eau parcimonieux, qui comprend des moyens grâce auxquels il est possible de choisir entre deux volumes différents de vidange.Belgian patent No. 877,662 discloses a sparse flushing tank system, which includes means by which it is possible to choose between two different drain volumes.

Un tel système n'est guère satisfaisant parce que le mécanisme à tirette est généralement commandé machinalement sans tourner le bouton à tirette dans une position spécifique déterminée qui permet de choisir entre deux volumes différents de rinçage.
Une fois que le bouton à tirette a été enclenché, il est alors généralement trop tard pour encore vite modifier la quantité d'eau.Such a system is hardly satisfactory because the pull mechanism is generally controlled mechanically without turning the pull button in a specific determined position which makes it possible to choose between two different rinsing volumes.
Once the pull button has been pressed, it is usually too late to quickly change the amount of water.

Ces systèmes de dosage d'eau de vidange comprennent généralement deux parties :

  • une partie supérieure qui est tirée vers le haut à l'aide d'un bouton à tirette et qui retombe immédiatement dès qu'on lâche le bouton, et
  • une partie inférieure qui est tirée vers le haut au moyen de la partie supérieure susdite et qui reste flotter entre deux eaux aussi longtemps que de l'eau est présente dans le réservoir de chasse d'eau.
These drain water metering systems generally consist of two parts:
  • an upper part which is pulled upwards using a pull button and which drops immediately as soon as the button is released, and
  • a lower part which is pulled upwards by means of the above-mentioned upper part and which remains floating between two waters as long as water is present in the flush tank.

La partie supérieure consiste en une tige tubulaire pourvue à l'extrémité supérieure d'un bouton fixe à tirette. La tige sert de guide à la partie supérieure. La partie inférieure comprend une tige intérieure coulissante à tirette et un bouchon d'obturation qui est fixé à l'extrémité inférieure de la tige. La tige est reliée à la tige tubulaire par une butée. Le bouchon d'obturation est généralement formé d'un joint en caoutchouc en forme de cloche, dont les rebords lisses reposent sur le fond du réservoir de chasse d'eau.The upper part consists of a tubular rod provided at the upper end with a fixed pull button. The rod serves as a guide for the upper part. The lower part includes a sliding inner rod with a pull tab and a plug which is fixed to the lower end of the rod. The rod is connected to the tubular rod by a stop. The blanking plug is usually made of a rubber bell-shaped seal, the smooth edges of which rest on the bottom of the flush tank.

Une variante consiste en ce que la tige tubulaire à tirette est entraînée vers le bas par le bouchon d'obturation et son flotteur.A variant consists in that the tubular rod with zipper is driven downwards by the closure plug and its float.

La problème technique réside à développer des accessoires, qui puissent être montés sur chaque dispositif de dosage existant, afin de restreindre la consommation d'eau des réservoirs de vidange, aux besoins réels sans avoir à choisir d'avance une quantité d'eau de vidange déterminée. Dans ce but, un dispositif de dosage, comme représenté dans le premier paragraphe de ce mémoire, est pourvu de moyens qui interrompent la vidange dès qu'on relâche le bouton à tirette.The technical problem lies in developing accessories, which can be mounted on each existing dosing device, in order to restrict consumption of water from the drain tanks, to the actual needs without having to choose in advance a determined quantity of drain water. To this end, a metering device, as shown in the first paragraph of this specification, is provided with means which interrupt the emptying as soon as the pull button is released.

Suivant une première forme de réalisation de l'invention, les moyens susdits sont un lest qui augmente le poids du bouchon d'obturation. Le lest est fixé sur la tige tubulaire du bouchon d'obturation, afin de contrer l'insubmersibilité du bouchon d'obturation et accélérer l'obturation étanche de l'orifice d'évacuation, une fois que le bouchon d'obturation est tiré vers le haut et relâché.According to a first embodiment of the invention, the above-mentioned means are a ballast which increases the weight of the closure plug. The ballast is fixed on the tubular rod of the closure plug, in order to counter the insubmersibility of the closure plug and to accelerate the sealed closure of the discharge orifice, once the closure plug is pulled towards up and relaxed.

Par la pose d'un lest, la flottabilité de la partie inférieure du système de dosage et du bouchon d'obturation est accrue et l'ensemble, formé par la tige tubulaire et le bouchon d'obturation, se comporte comme une tige rigide depuis le bouchon d'obturation jusqu'au bouton à tirette.By installing a ballast, the buoyancy of the lower part of the metering system and the plug is increased and the assembly, formed by the tubular rod and the plug, behaves like a rigid rod from the sealing plug up to the pull button.

Cette amélioration est avant tout intéressante parce qu'elle peut être insérée dans n'importe quel système.This improvement is above all interesting because it can be inserted into any system.

Ces caractéristiques et d'autres caractéristiques et particularités de l'invention seront exposées plus en détail ci-après dans la description d'une forme de réalisation spécifique de l'invention, donnée plutôt à titre d'exemple illustratif et non limitatif, en faisant référence aux dessins ci-joints dans lesquels :

  • la figure 1, est une coupe transversale d'un réservoir de chasse d'eau pourvu d'un dispositif de dosage selon l'invention, l'orifice d'évacuation étant fermé;
  • la figure 2, est une coupe identique à celle de la figure 1, illustrée dans une position dans laquelle on tire la chasse;
  • la figure 3, est une vue identique à celle ci-dessus d'une seconde forme de réalisation d'un dispositif de dosage selon l'invention.
These characteristics and other characteristics and particularities of the invention will be explained in more detail below in the description of a specific embodiment of the invention, given rather by way of illustrative and nonlimiting example, by making reference to the attached drawings in which:
  • Figure 1 is a cross section of a flush tank provided with a metering device according to the invention, the discharge opening being closed;
  • Figure 2 is a section identical to that of Figure 1, illustrated in a position in which we flush;
  • Figure 3 is a view identical to that above of a second embodiment of a metering device according to the invention.

Dans ces figures les mêmes signes de référence désignent des éléments identiques ou analogues.In these figures, the same reference signs designate identical or analogous elements.

Dans la figure 1 on a représenté un réservoir de chasse 1 classique pour W.-C. Le fond 2 du réservoir 1 comprend un orifice d'évacuation 3 et un bouchon d'obturation 4. Le mécanisme de commande 5 du dispositif de dosage comprend généralement un mécanisme à tirette constitué d'un bouton à tirette 6, une tige 7, un guide 9 pour la tige 7, une butée 11 et le bouchon d'obturation 4.In FIG. 1, a conventional flush tank 1 for WC has been represented. The bottom 2 of the tank 1 comprises an evacuation orifice 3 and a closure plug 4. The control mechanism 5 of the metering device comprises generally a pull mechanism consisting of a pull button 6, a rod 7, a guide 9 for the rod 7, a stop 11 and the closure plug 4.

Le bouchon d'obturation 4 peut être tiré vers le haut au moyen de la tige 7 et du bouton à tirette 6. Le bouchon d'obturation 4 est, dans une forme de réalisation particulière, un joint en caoutchouc en forme de cloche, dont les bords inférieurs lisses reposent sur le fond 2 du réservoir de chasse 1. Par la pression hydrostatique de l'eau, le bouchon d'obturation veille à une fermeture étanche de l'orifice d'évacuation 3, comme illustré dans la figure 1.The closure plug 4 can be pulled upwards by means of the rod 7 and the pull button 6. The closure plug 4 is, in a particular embodiment, a bell-shaped rubber seal, of which the smooth lower edges rest on the bottom 2 of the flushing tank 1. By the hydrostatic pressure of the water, the sealing plug ensures a tight closure of the discharge orifice 3, as illustrated in FIG. 1.

Lorsqu'on tire le bouchon d'obturation vers le haut à l'aide du bouton de tirette 6 et la tige 7, le bouchon d'obturation en forme de cloche à tendance, dans un réservoir de chasse 1 classique, à flotter dans l'eau, tandis que l'eau de vidange s'écoule par le conduit d'évacuation. Grâce à l'air présent dans la partie supérieure de la cloche, le bouchon d'obturation est, à ce moment, toujours plus léger que l'eau. Le bouchon d'obturation reste flotter dans l'eau, aussi longtemps que de l'eau est présente dans le réservoir de chasse 1 de sorte que la totalité du volume d'eau du réservoir de chasse se vide entièrement (figure 2).When the closure plug is pulled up using the pull button 6 and the rod 7, the bell-shaped closure plug tends to float in the conventional cistern 1 while the drain water flows through the drain. Thanks to the air present in the upper part of the bell, the plug is, at this time, always lighter than water. The plug remains floating in the water, as long as water is present in the flush tank 1 so that the entire volume of water in the flush tank is completely emptied (Figure 2).

L'équipement consiste à munir le dispositif de dosage de moyens qui obturent l'orifice d'évacuation 3 dès que le bouton 6 est relâché.The equipment consists of providing the metering device with means which close the discharge orifice 3 as soon as the button 6 is released.

Dans une première forme de réalisation, le bouchon à tirette est un joint en caoutchouc en forme de cloche. On augmente le poids du bouchon d'obturation 4 au moyen d'un lest 8, qui est fixé sur la tige de traction 7 du bouchon d'obturation 4, afin de contrer l'insubmersibilité du bouchon d'obturation 4.In a first embodiment, the zipper plug is a bell-shaped rubber seal. The weight of the closure plug 4 is increased by means of a ballast 8, which is fixed to the draw rod 7 of the closure plug 4, in order to counter the unsinkability of the closure plug 4.

Par ce moyen, le bouchon d'obturation 4 s'affaisse et recouvre l'orifice d'évacuation dès qu'on relâche le bouton à tirette 6. Le débit d'eau de vidange peut être déterminé à chaque opération de vidange en fonction de la durée de l'intervalle de temps pendant lequel le bouton à tirette est commandé.By this means, the closure plug 4 collapses and covers the discharge orifice as soon as the pull button 6 is released. The drain water flow rate can be determined at each drain operation as a function of the duration of the time interval during which the pull button is operated.

Dans une seconde forme de réalisation, la tige à tirette du système de dosage est pourvue d'un piston 12 qui se déplace de haut en bas le long d'une chambre cylindrique 14.
La partie supérieure de la chambre est étroite et exerce une certaine friction sur le piston 12. La partie inférieure de la chambre 14 s'élargit et empêche le frottement. Le piston 12 est alourdi par un lest 8 qui forme corps avec le piston 12. Lorsqu'on commande la tige à tirette, le bouchon d'obturation est tiré vers le haut et le piston 12 soulevé. Lorsqu'on relâche la tige à tirette 8, le piston descend lentement sous la pesanteur jusqu'à l'endroit d'évasement.In a second embodiment, the pull rod of the metering system is provided with a piston 12 which moves up and down along a cylindrical chamber 14.
The upper part of the chamber is narrow and exerts a certain friction on the piston 12. The lower part of the chamber 14 widens and prevents friction. The piston 12 is weighed down by a ballast 8 which forms a body with the piston 12. When the pull rod is controlled, the closure plug is pulled up and the piston 12 raised. When the pull rod 8 is released, the piston slowly descends under gravity to the point of flaring.

A partir de l'endroit où le chambre cylindrique s'élargit, le piston 12 ne ressent plus aucune friction. Le piston 12 s'affaisse et entraîne le bouchon d'obturation 4 dans sa chute avec la tige à tirette 7. L'intervalle de temps pendant lequel le piston et de même le bouchon d'obturation 4 et qui est maintenu en haut, peut être choisi en prévoyant un certain orifice 13 dans le piston ou un certain interstice entre le piston et la chambre (figure 3).From the point where the cylindrical chamber widens, the piston 12 no longer feels any friction. The piston 12 collapses and drives the closure plug 4 in its fall with the pull rod 7. The interval of time during which the piston and likewise the closure plug 4 and which is held at the top, can be chosen by providing a certain orifice 13 in the piston or a certain gap between the piston and the chamber (FIG. 3).
