Abstract

The cistern has a tap (1) for filling, an emptying mechanism and two control rods (23,24) connected to a sliding horizontal valve (11) with a ball (7). After filling, the valve mechanism is closed by a float (18). The cistern is emptied by lifting a tube (25) with floats (31,32) which can be raised to two different levels, depending on whether a short or long flush is required. The height to which the tube is raised depends on the position of a triangular plate (35) which interacts with a stop (33) projecting from the side of the tube.

Description

Dans le but d'économiser l'eau dans les WC il est fait appel de plus en plus à des systèmes à double chasse qui évitent le gaspillage en limitant cette consommation aux seuis nécessités fonctionnelles. In order to save water in toilets, there is an increasing use of dual flush systems which avoid waste by limiting this consumption to the minimum functional requirements.

La présente invention se rapporte à un tel mécanisme à double chasse d'une extreme simplicité et d'un fonctionnement à la fois sur et précis.The present invention relates to such a dual flush mechanism of extreme simplicity and operation both safe and precise.

Le tube de trop plein qui porte à sa base le clapet de vidage porte également un flotteur fixé sur sa partie inférieure. The overflow tube which carries the drain valve at its base also carries a float fixed on its lower part.

Dans la première phase de soulèvement du tube, celui subit une aspiration qui tend à le faire retomber tandis que, dans la deuxième phase du
soulèvement, il échappe à cette aspiration pour être entrainé dans un mouvement ascendant sous l'effet dominant de la poussé d'Archimède qui s'applique sur le flotteur.In the first phase of lifting the tube, it undergoes a suction which tends to make it fall down while, in the second phase of the
uprising, he escapes this aspiration to be drawn in an upward movement under the dominant effect of the Archimedes thrust which applies to the float.

Sur la partie médiane du tube est fixé un autre flotteur dont la poussée ascendante qu'il subit, s'ajoutant à celle qui s'applique au flotteur de base, entraîne le tube en soulèvement libre lorsqu'on appuie sur l'une des tiges de commande. On the median part of the tube is fixed another float whose upward thrust which it undergoes, in addition to that which applies to the basic float, causes the tube to lift free when one of the rods is pressed control.

L'amplitude de ce soulèvement est réglée de manière à ce que le tube soit
maintenu en suspension même après que le flotteur intermédiaire ait cessé d'être
immergé, le flotteur de base restant alors en dehors de la zone d'aspiration . Ce processus correspond à la grande chasse.The amplitude of this lifting is adjusted so that the tube is
maintained in suspension even after the intermediate float has ceased to be
submerged, the basic float then remaining outside the suction zone. This process corresponds to the big hunt.

La petite chasse, actionnée par l'autre tige de commande est obtenue par l'action d'une butée qui limite mécaniquement le soulèvement du tube lequel se trouve maintenu à un niveau où il serait instantanément aspiré vers le bas dans le cas où, il n'y aurait pas de flotteur intermédiaire. La fonction de ce dernier est précisément de temporiser cette retombée pour permettre le déversement de la petite chasse. The small flush, actuated by the other control rod is obtained by the action of a stop which mechanically limits the lifting of the tube which is kept at a level where it would be instantly sucked down in the event that, it there would be no intermediate float. The function of the latter is precisely to delay this fallout to allow the dumping of small game.

Cette temporisation est rendue possible par le fait que la poussée ascendante qui s'exerce sur ce flotteur intermédiaire est supérieure à la force d'aspiration et ceci pendant toute la phase ou ledit flotteur reste immergé. This time delay is made possible by the fact that the upward thrust exerted on this intermediate float is greater than the suction force and this during the entire phase where said float remains immersed.

Pour bien comprendre l'invention, on pourra utilement se référer à la figure 1 ci-annexée donnée à titre d'exemple non limitatif et qui fait apparaitre également le
dispositif par lequel la butée de petite chasse s'escamote à l'occasion de la grande chasse.To fully understand the invention, reference may usefully be made to FIG. 1 appended hereto given by way of nonlimiting example and which also shows the
device by which the small hunting stop retracts during big hunting.

Le réservoir (1) comporte, ménagé dans son fond, un orifice d'expulsion (2) sur la périphérie duquel se place un siège d'étanchéité (3). The reservoir (1) comprises, formed in its bottom, an expulsion orifice (2) on the periphery of which is placed a sealing seat (3).

Le tube vertical de trop plein (4) porte à sa base le clapet (5) qui se place
sur le siège (3).The vertical overflow tube (4) carries at its base the valve (5) which is placed
on the seat (3).

Le tube (4) porte à sa partie inférieure un flotteur (6), dans sa partie médiane un flotteur (7) et. au dessus de (7) une plaque horizontale (8). The tube (4) carries a float (6) in its lower part, in its middle part a float (7) and. above (7) a horizontal plate (8).

Le soulèvement du tube s'effectue par l'intermédiaire des systèmes connus comme, par exemple, deux leviers identiques (9) et (10) pivotant autour d'un
axe horizontal commun (11) et sur lesquels agissent les tiges verticales (12) et (13).The lifting of the tube is carried out by means of known systems such as, for example, two identical levers (9) and (10) pivoting around a
common horizontal axis (11) and on which act the vertical rods (12) and (13).

Les tiges (12) et (13) sont fixées sur les faces inférieures des plaques
horizontales (14) et (15) elles-mêmes surmontées des tiges verticales de commande
(16) et (17).The rods (12) and (13) are fixed to the undersides of the plates
horizontal (14) and (15) themselves surmounted by vertical control rods
(16) and (17).

Autour d'un axe fixe (18) parallèle à (11) pivote librement une plaque (19) tandis que le dessous de l'une des plaques de commande par exemple (14) porte une tige verticale (20). Around a fixed axis (18) parallel to (11) freely pivots a plate (19) while the underside of one of the control plates for example (14) carries a vertical rod (20).

La plaque (19) est disposée et suspendue de manière à ce que, en position, normale de pesanteur, I'un de ses côtés constitue une rampe inclinée (21) dont l'extrémité inférieure (22) se situe dans l'espace de soulèvement de la plaque (8). The plate (19) is arranged and suspended so that, in the normal gravity position, one of its sides constitutes an inclined ramp (21) whose lower end (22) is located in the space of lifting the plate (8).

L'ensemble est aménagé de manière à ce que, avec l'enfoncement de la plaque (14), I'extrémité (23) de la tige (20) glisse le long de la rampe (21) en faisant pivoter la plaque (19) jusqu'à dégager complètement l'espace de soulèvement de la plaque (8) comme le montre la figuration en pointillé. The assembly is arranged so that, with the depression of the plate (14), the end (23) of the rod (20) slides along the ramp (21) by pivoting the plate (19 ) until completely clearing the lifting space of the plate (8) as shown in the dotted lines.

On comprend que si on avait utilisé la tige de commande (17) correspondant à la plaque (15), la plaque (19) serait restée en place et aurait agi en butée contre la plaque (8). Pour permettre l'adaptation du mécanisme selon l'invention à des réservoirs de dimensions diverses et pouvoir moduler le volume de la petite chasse, le flotteur (7) est réglable en hauteur.  It is understood that if we had used the control rod (17) corresponding to the plate (15), the plate (19) would have remained in place and would have acted in abutment against the plate (8). To allow the mechanism according to the invention to be adapted to tanks of various dimensions and to be able to modulate the volume of the small flush, the float (7) is adjustable in height.
