Description

Le domaine de l'invention est celui de la conception et de la fabrication des équipements sanitaires. Plus précisément, l'invention concerne un mécanisme de chasse d'eau destiné à être monté sur un réservoir d'eau de toilettes, du type comprenant des moyens d'actionnement du mécanisme de la chasse d'eau sous forme d'au moins un bouton poussoir.The field of the invention is that of the design and manufacture of sanitary equipment. More specifically, the invention relates to a flushing mechanism intended to be mounted on a toilet water tank, of the type comprising means for actuating the flushing mechanism in the form of at least one pushbutton.

Dans le domaine de l'invention, il est connu de proposer des mécanismes de chasse d'eau comprenant un bâti monté dans le réservoir d'eau des toilettes, ce bâti comprenant un moyen d'obturation d'un orifice ménagé dans une paroi inférieure (au fond) du réservoir et au travers duquel l'eau du réservoir peut être évacuée, ces moyens d'obturation étant reliés par un mécanisme de transmission à des moyens d'actionnement accessibles de l'extérieur du réservoir par un utilisateur.In the field of the invention, it is known to provide flushing mechanisms comprising a frame mounted in the water tank of the toilet, this frame comprising means for closing an orifice formed in a lower wall. (at the bottom) of the tank and through which the water from the tank can be discharged, these sealing means being connected by a transmission mechanism to actuation means accessible from outside the tank by a user.

Selon une approche assez ancienne, ces moyens d'actionnement peuvent être constitués par une tirette, c'est-à-dire par un moyen de préhension à l'extrémité d'une tige destinée à être tirée vers le haut pour provoquer l'évacuation de l'eau à partir du réservoir. Ainsi, clairement, en déplaçant la tirette vers le haut, on provoque également un déplacement vers le haut des moyens d'obturation de la chasse et, inversement, en relâchant la tirette, celle-ci, ainsi que les moyens d'obturation se déplacent vers le bas jusqu'à ce que les moyens d'obturation reprennent leur position d'obturation de l'orifice ménagé dans la paroi inférieure du réservoir.According to a fairly old approach, these actuating means can be constituted by a pull tab, that is to say by a gripping means at the end of a rod intended to be pulled upwards to cause evacuation water from the tank. Thus, clearly, by moving the zipper upwards, one also causes an upward displacement of the means for shutting off the flush and, conversely, by releasing the zipper, the latter, as well as the shutter means move downwards until the closure means resume their position for closing the orifice provided in the lower wall of the tank.

Selon une approche plus récente mais toutefois déjà très largement répandue, les moyens d'actionnement sont constitués par un bouton poussoir (ou par deux boutons poussoirs, l'un pour libérer une « grande chasse » et l'autre pour libérer une « petite chasse ») présentés sur une paroi supérieure (en pratique le couvercle) du réservoir, de telle sorte que l'utilisateur doit enfoncer le bouton poussoir vers l'intérieur du réservoir pour provoquer une chasse d'eau. Bien entendu, dans ce cas, il est nécessaire de mettre en œuvre un système qui inverse la course du bouton poussoir au niveau des moyens d'obturation, de telle sorte qu'un déplacement vers le bas du ou des boutons poussoirs se traduisent par un déplacement vers le haut des moyens d'obturation, tandis qu'un déplacement vers le haut du ou des boutons poussoirs se traduit par un déplacement vers le bas des moyens d'obturation.According to a more recent but already widely used approach, the actuating means are constituted by a push button (or by two push buttons, one to release a "big game" and the other to release a "small game" ») Presented on an upper wall (in practice the cover) of the tank, so that the user must push the push button towards the inside of the tank to cause a flush. Of course, in this case, it is necessary to implementing a system which reverses the travel of the push button at the shutter means, so that a downward movement of the push button (s) results in an upward movement of the shutter means, while that an upward movement of the push button or buttons results in a downward movement of the shutter means.

Pour obtenir cela, on monte à l'intérieur du réservoir un système inverseur à levier, ce levier étant monté pivotant autour d'un axe porté soit par le bâti du mécanisme de chasse d'eau monté à l'intérieur du réservoir, soit par la paroi du réservoir lui-même. Une des extrémités du levier est reliée par une tige de liaison au bouton poussoir, tandis que l'autre extrémité du levier (opposé à la première extrémité par rapport à l'axe de pivotement) est reliée aux moyens d'obturation.To obtain this, a lever reverser system is mounted inside the tank, this lever being pivotally mounted about an axis carried either by the frame of the flushing mechanism mounted inside the tank, or by the wall of the tank itself. One end of the lever is connected by a connecting rod to the push button, while the other end of the lever (opposite the first end with respect to the pivot axis) is connected to the closure means.

Un tel mécanisme donne globalement satisfaction et s'avère relativement fiable.Such a mechanism gives overall satisfaction and is relatively reliable.

Pour installer un mécanisme de chasse d'eau du type à bouton poussoir tel que décrit précédemment, le couvercle du réservoir est retiré et il est procédé à l'installation du bâti du mécanisme de chasse à l'intérieur du réservoir. La tige de liaison mentionnée précédemment, s'étendant à partir d'une extrémité du système inverseur à levier, est donc présent au-dessus du bâti du mécanisme de chasse d'eau en attente d'être couplée au bouton poussoir.To install a flushing mechanism of the push button type as described above, the tank cover is removed and the frame of the flushing mechanism is installed inside the tank. The connecting rod mentioned above, extending from one end of the lever reverser system, is therefore present above the frame of the flushing mechanism waiting to be coupled to the push button.

Le corps creux qui loge le bouton poussoir et à l'intérieur duquel le bouton poussoir est monté mobile, est disposé et fixé sur le couvercle du réservoir, puis le couvercle est rapporté sur le réservoir tandis que l'installateur fait en sorte de faire coïncider la position de la tige de liaison avec le bouton poussoir.The hollow body which houses the push button and inside which the push button is movably mounted, is arranged and fixed on the tank cover, then the cover is attached to the tank while the installer makes sure to coincide the position of the connecting rod with the push button.

Une fonction désormais classique consiste à intégrer au bouton poussoir une fonction de sélection « petite chasse »/ « grande chasse », permettant à l'utilisateur de réaliser des économies d'eau en effectuant seulement une petite chasse d'eau s'il le juge opportun.A now classic function consists in integrating with the push button a selection function "small flush" / "large flush", allowing the user to save water by performing only a small flush if he judges it timely.

Pour ce faire, le bouton poussoir est divisé en deux parties actionnables indépendamment l'une de l'autre, l'une correspondant à une « grande chasse », et l'autre à une « petite chasse ». Pour les distinguer, il est usuel de présenter la partie « grande chasse » avec des dimensions notablement plus grandes que la partie « petite chasse ». Ainsi, les deux parties peuvent être disposées l'une à côté de l'autre ou, selon certaines alternatives, la partie « petite chasse » est entourée par la partie « grande chasse ».To do this, the push button is divided into two parts that can be actuated independently of one another, one corresponding to a "big game", and the other to a "small game". To distinguish them, it is customary to present the "big game" part with significantly larger dimensions than the "small game" part. Thus, the two parts can be arranged one next to the other or, according to certain alternatives, the "small game" part is surrounded by the "big game" part.

Outre le fait que, dans certains cas, il n'est pas toujours pratique d'actionner la partie « petite chasse » sans entraîner la partie la partie « grande chasse », l'agencement et la présentation des boutons poussoirs offrant ce type de possibilités sont relativement constants et ne permettent donc pas de proposer de nouvelles déclinaisons fonctionnelles et/ou esthétiques.In addition to the fact that, in certain cases, it is not always practical to actuate the part "small hunting" without training the part the part "large hunting", the arrangement and the presentation of the push buttons offering this type of possibilities are relatively constant and therefore do not allow new functional and / or aesthetic variations to be proposed.

Une solution alternative a été décrite dans le document de brevet publié sous le numéro FR2665201 , qui concerne un dispositif de commande de chasse d'eau pour WC qui permet d'économiser l'eau, en programmant au choix le volume d'eau nécessaire au bon nettoyage de la cuvette. L'invention proposée se présente sous la forme d'un bouton de commande fixé sur le couvercle du réservoir. Le bouton est constitué de deux bagues ajourées : une bague extérieure mobile, une bague intérieure fixe. La rotation du bouton se fait par l'intermédiaire d'une poignée fixée sur la bague extérieure mobile, qui par un jeu de tétons se déplaçant des ouvertures formant des rampes, transmet au piston un mouvement vertical qui fait monter, ou descendre, une tige de commande qui actionne, ou arrête, la vidange du réservoir. Pour choisir un volume de vidange plus ou moins important, il suffit de régler le bouton dans un secteur compris entre 90° et 180° maxi. Plus la rotation est importante, plus la tige de commande reste en position haute longtemps permettant ainsi à un plus grand volume d'eau de s'écouler Une fois le réglage choisi, on lâche la poignée du bouton, un ressort de rappel circulaire travaillant en traction ramène alors vers la position initiale la bague extérieure mobile; celle-ci entraîne dans sa course les tétons du piston qui, abaissent la tige de commande et interrompent l'opération de vidange.An alternative solution has been described in the patent document published under the number FR2665201 , which concerns a toilet flush control device which saves water, by programming as desired the volume of water necessary for the proper cleaning of the bowl. The proposed invention is in the form of a control button attached to the tank cover. The button consists of two openwork rings: a movable outer ring, a fixed inner ring. The rotation of the button is done by means of a handle fixed on the movable outer ring, which by a set of pins moving from the openings forming ramps, transmits to the piston a vertical movement which makes raise, or lower, a rod that activates or stops the emptying of the tank. To choose a more or less large emptying volume, simply set the button in a sector between 90 ° and 180 ° max. The greater the rotation, the longer the control rod remains in the high position allowing a larger volume of water to flow. Once the setting is chosen, the handle of the button is released, a circular return spring working in traction then brings the movable outer ring back to the initial position; this drives the piston pins which, lower the control rod and interrupt the emptying operation.

Un tel dispositif de commande propose certes un nouveau mode de sélection du volume de chasse d'eau, mais s'avère de conception complexe, mettant en œuvre un nombre de pièces relativement important, mobiles les unes par rapport aux autres, dont le montage et l'assemblage rendent en pratique une telle solution peu viable à un niveau industriel.Such a control device certainly offers a new method of selecting the flush volume, but turns out to be complex in design, using a relatively large number of parts, movable relative to one another, including the mounting and assembly make in practice such a solution not very viable at an industrial level.

D'autres dispositifs de chasse d'eau sont décrits dans US20160281342 , DE29510495U , NL9100986 .Other flushing devices are described in US20160281342 , DE29510495U , NL9100986 .

L'invention a notamment pour objectif de pallier ces inconvénients de de l'art antérieur.The invention particularly aims to overcome these drawbacks of the prior art.

Plus précisément, l'invention a pour objectif de proposer un dispositif de commande de mécanisme de chasse d'eau à bouton poussoir, procurant la possibilité de sélectionner le volume de chasse à exécuter, qui offre des possibilités étendues par rapport aux boutons double chasse traditionnels, tant en termes de fonctionnalités que de présentation visuelle.More specifically, the invention aims to propose a device for controlling a flushing mechanism with a push button, providing the possibility of selecting the flush volume to be executed, which offers extended possibilities compared to traditional dual flush buttons. , both in terms of functionality and visual presentation.

L'invention a également pour objectif de fournir un tel dispositif de commande à bouton poussoir qui soit simple de conception et facile à mettre en œuvre.The invention also aims to provide such a push button control device which is simple in design and easy to implement.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un dispositif de commande de chasse d'eau destiné à être monté sur un réservoir d'eau de toilettes, comprenant un bouton poussoir monté mobile en translation selon un axe de poussée à l'intérieur d'un corps creux destiné à être monté sur un couvercle du réservoir, le dispositif de commande comprenant un organe sélecteur monté mobile en rotation autour de l'axe de poussée pour choisir un volume de chasse, le corps creux comprenant un fond présentant au moins une ouverture principale pour le passage d'un organe de liaison destiné à relier le bouton poussoir à un mécanisme de chasse, caractérisé en ce que le fond du corps creux présente au moins une ouverture secondaire, et en ce que le bouton poussoir présente au moins une butée apte à être engagée au travers de l'ouverture secondaire du fond, l'organe sélecteur étant mobile en rotation entre au moins deux positions :

  • une position autorisant l'engagement de la butée au travers de l'ouverture secondaire du fond ;
  • une position bloquant l'engagement de la butée au travers de l'ouverture secondaire du fond.
These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to a flushing control device intended to be mounted on a toilet water tank, comprising a button pusher mounted movable in translation along a thrust axis inside a hollow body intended to be mounted on a tank cover, the control device comprising a selector member mounted movable in rotation about the thrust axis to choose a flush volume, the hollow body comprising a bottom having at least one main opening for the passage of a connecting member intended to connect the push button to a flush mechanism, characterized in that the bottom of the hollow body has at least a secondary opening, and in that the push button has at least one stop capable of being engaged through the secondary opening of the bottom, the selector member being movable in rotation in be at least two positions:
  • a position authorizing the engagement of the stop through the secondary opening of the bottom;
  • a position blocking the engagement of the stopper through the secondary opening of the bottom.

Ainsi, l'invention propose un dispositif de commande offrant une alternative à la mise en œuvre classique des boutons poussoirs en deux parties mentionnés en référence à l'art antérieur.Thus, the invention provides a control device offering an alternative to the conventional implementation of two-part push buttons mentioned with reference to the prior art.

Comme cela va apparaître clairement par la suite, un dispositif de commande selon l'invention met en œuvre un nombre de pièces réduit, peu chers à fabriquer et impliquant un montage et un assemblage aisé et rapide, permettant de réaliser industriellement un tel dispositif avec un prix de fabrication relativement faible.As will become clear below, a control device according to the invention implements a reduced number of parts, inexpensive to manufacture and involving easy and rapid assembly and assembly, making it possible to produce such a device industrially with a relatively low manufacturing price.

Préférentiellement, caractérisé en ce que l'organe sélecteur comprend une partie manipulable présentée en partie supérieur du corps creux.Preferably, characterized in that the selector member comprises a manipulable part presented in the upper part of the hollow body.

Un tel agencement offre la possibilité à chaque utilisateur de procéder à une sélection du volume de chasse d'eau. Il est toutefois envisageable que l'invention soit utilisée avec un sélecteur non accessible à l'utilisateur une fois le dispositif monté sur le réservoir, l'installateur procédant au positionnement du sélecteur en fonction du type de chasse qu'il impose alors à toutes utilisations ultérieures.Such an arrangement offers the possibility for each user to make a selection of the flush volume. It is however conceivable that the invention is used with a selector not accessible to the user once the device is mounted on the tank, the installer positioning the selector according to the type of flush which it then imposes for all uses. later.

Selon une solution préférentielle, la partie manipulable s'étend en partie supérieure d'une cuve à l'intérieur de laquelle le bouton poussoir est monté mobile en translation selon l'axe de poussée.According to a preferred solution, the manipulable part extends in the upper part of a tank inside which the push button is mounted movable in translation along the thrust axis.

De cette façon, la cuve accueillant le bouton poussoir intègre la partie manipulable, la cuve et la partie manipulable formant une unique pièce, qui tend à permettre une limitation des coûts de fabrication et de montage.In this way, the tank accommodating the push button integrates the manipulable part, the tank and the manipulable part forming a single piece, which tends to allow a limitation of the manufacturing and assembly costs.

Préférentiellement, la cuve est guidée en rotation autour de l'axe de poussée par l'intermédiaire de la partie manipulable qui forme une liaison glissière avec le corps creux.Preferably, the tank is guided in rotation around the thrust axis by means of the manipulable part which forms a sliding connection with the hollow body.

La rotation de la partie manipulable, et donc de la cuve, est obtenue selon un montage fiable, assurant une bonne tenue mécanique dans le temps et procurant une perception de précision et de qualité à l'utilisateur.The rotation of the manipulable part, and therefore of the tank, is obtained according to a reliable assembly, ensuring good mechanical strength over time and providing a perception of precision and quality to the user.

Selon un mode de réalisation particulier, le bouton poussoir présente une interface de poussée présentant un indicateur, la partie manipulable de l'organe sélecteur portant au moins deux repères de choix de volume de chasse, destinés à être placés en correspondance avec l'indicateur.According to a particular embodiment, the push button has a push interface having an indicator, the manipulable part of the selector member carrying at least two marks for choosing the flush volume, intended to be placed in correspondence with the indicator.

Bien entendu, d'autres dispositions sont envisageables sans sortir du cadre de l'invention, par exemple en portant les repères sur l'organe sélecteur et l'indicateur sur le bouton poussoir.Of course, other arrangements can be envisaged without departing from the scope of the invention, for example by wearing the marks on the selector member and the indicator on the push button.

Avantageusement, le dispositif comprend un ressort de rappel intercalé entre le bouton poussoir et l'organe sélecteur et/ou le corps creux, le ressort de rappel tendant à repousser le bouton poussoir vers le haut.Advantageously, the device comprises a return spring interposed between the push button and the selector member and / or the hollow body, the return spring tending to push the push button up.

Selon une première variante de réalisation, l'organe sélecteur comprend une partie obturatrice intercalée entre le bouton poussoir et le fond du corps creux, et présentant au moins un passage apte à être placé en coïncidence avec l'ouverture secondaire pour autoriser l'engagement de la butée au travers de l'ouverture secondaire.According to a first alternative embodiment, the selector member comprises a shutter portion interposed between the push button and the bottom of the hollow body, and having at least one passage capable of being placed in coincidence with the secondary opening to authorize the engagement of the stopper through the secondary opening.

Dans ce cas, le bouton poussoir présente avantageusement deux butées constitués chacune par un montant cylindrique, les butées étant positionnées de part et d'autre de l'organe de liaison, la partie obturatrice et le fond du corps creux présentant l'une un passage et l'autre une ouverture secondaire pour chaque montant cylindrique, les passages et ouvertures secondaires étant positionnées de façon à pouvoir être traversées simultanément par les montants cylindriques.In this case, the push button advantageously has two stops each consisting of a cylindrical upright, the stops being positioned on either side of the connecting member, the shutter part and the bottom of the hollow body having one passage and the other a secondary opening for each cylindrical upright, the passages and secondary openings being positioned so that they can be traversed simultaneously by the cylindrical uprights.

Selon une deuxième variante de réalisation, la ou les butées s'étendent angulairement autour de l'axe de poussée, et présentent au moins deux crans angulaires dont l'un bas et l'autre haut, la ou les ouvertures secondaires s'étendant angulairement de façon à pouvoir être traversées par le cran bas uniquement ou par le cran bas et le cran haut ensemble .According to a second alternative embodiment, the stop or stops extend angularly around the thrust axis, and have at least two angular notches, one of which is low and the other high, the secondary opening (s) extending angularly so that it can be crossed by the bottom notch only or by the bottom notch and the top notch together.

Avec une telle variante de réalisation, il est possible d'augmenter le nombre de positions sélectionnables et, par conséquent, le nombre de volumes de chasses différents susceptibles d'être choisis par l'utilisateur (ou l'installateur).With such an alternative embodiment, it is possible to increase the number of selectable positions and, consequently, the number of different flush volumes likely to be chosen by the user (or installer).

Selon d'autres modes de réalisation envisageables, l'organe sélecteur est constitué :

  • soit par le bouton poussoir lui-même, mobile en rotation par rapport au corps creux ;
  • soit par le corps creux lui-même, monté mobile en rotation par rapport au bouton poussoir.
According to other possible embodiments, the selector member consists of:
  • either by the push button itself, movable in rotation relative to the hollow body;
  • either by the hollow body itself, mounted movable in rotation relative to the push button.

Tel qu'indiqué précédemment, l'invention s'applique à un dispositif de commande d'un mécanisme de chasse d'eau destiné à être monté sur un réservoir d'eau de toilettes. Un tel mécanisme de chasse d'eau et son dispositif de commande comprennent classiquement :

  • un bouton poussoir 1, destiné à être présenté sur le couvercle 10 du réservoir lui-même prévu pour venir reposer sur le rebord supérieur du réservoir pour refermer celui-ci, le bouton poussoir étant mobile de haut en bas et inversement ;
  • un bâti destiné à être monté à l'intérieur du réservoir et comprenant un moyen d'obturation mobile entre une position basse d'obturation, dans laquelle il obture un orifice de passage d'eau ménagé dans une paroi inférieure du réservoir, à la base de celui-ci et, une position haute de libération de l'orifice de passage d'eau (autorisant ainsi la libération d'une petite ou d'une grande chasse d'eau en direction de la cuvette des toilettes) ;
  • un mécanisme de transmission entre le bouton poussoir et le moyen d'obturation, comprenant généralement un système inverseur à levier, conçu pour inverser le déplacement en hauteur du ou des boutons poussoir par rapport au déplacement en hauteur du moyen d'obturation.
As indicated above, the invention applies to a device for controlling a flushing mechanism intended to be mounted on a toilet water tank. Such a flushing mechanism and its control device conventionally include:
  • a push button 1, intended to be presented on the cover 10 of the tank itself intended to come to rest on the upper rim of the tank to close the latter, the push button being movable from top to bottom and vice versa;
  • a frame intended to be mounted inside the tank and comprising a shutter means movable between a low shutter position, in which it closes a water passage orifice formed in a lower wall of the tank, at the base from it and a high position for releasing the water passage opening (thus authorizing the release of a small or large flush in the direction of the toilet bowl);
  • a transmission mechanism between the push button and the shutter means, generally comprising a lever reverser system, designed to reverse the height movement of the push button (s) relative to the height movement of the shutter means.

Le système inverseur à levier permet de transformer un déplacement de haut en bas du ou des boutons poussoir (correspondant en pratique à un appui sur le ou les boutons poussoirs) en un déplacement de bas en haut du moyen d'obturation (entraînant une chasse de l'eau) et, inversement, de transformer un déplacement de haut en bas du moyen d'obturation en un déplacement de bas en haut du ou des boutons poussoir. Cela correspond donc à une utilisation classique des boutons poussoirs des mécanismes de chasse d'eau selon laquelle lorsque l'utilisateur appuie sur le bouton poussoir, il engendre une chasse d'eau (moyen d'obturation position haute) tandis que, lorsque le moyen d'obturation reprend sa position d'obturation de l'orifice de passage d'eau du réservoir, donc en étant en position basse, son déplacement vers le bas entraîne une remontée du bouton poussoir en position d'attente.The lever reversing system makes it possible to transform a movement from top to bottom of the push button (s) (corresponding in practice to pressing on the push button (s)) to a movement from bottom to top of the shutter means (causing flushing water) and, conversely, to transform a displacement from top to bottom of the shutter means into a displacement from bottom to top of the push button (s). This therefore corresponds to a conventional use of the push buttons of the flushing mechanisms according to which when the user presses the push button, it generates a flush (means of shutter high position) while, when the means shutter resumes its closed position of the water passage opening of the tank, so being in the low position, its moving down causes the push button to go back up to the standby position.

Il est toutefois envisageable d'appliquer l'invention à un dispositif de commande incluant un autre type de bouton poussoir, tel qu'un bouton « tracteur », c'est-à-dire qui provoque une remontée du dispositif d'obturation lors du déplacement de bas en haut du bouton poussoir.It is however conceivable to apply the invention to a control device including another type of push button, such as a “tractor” button, that is to say which causes a rise in the shutter device during moving from bottom to top of the push button.

Par ailleurs, on note que le bâti (ou corps) du mécanisme de chasse d'eau, présent à l'intérieur du réservoir, peut présenter différentes parties constitutives et fonctionnelles connues de l'art antérieur, à savoir :

  • un flotteur, éventuellement réglable, destiné à stopper l'écoulement d'eau à l'intérieur du réservoir ;
  • un système de surverse ;
  • un culot à montage rapide ;
  • ...
Furthermore, it is noted that the frame (or body) of the flushing mechanism, present inside the tank, may have different constituent and functional parts known from the prior art, namely:
  • a float, possibly adjustable, intended to stop the flow of water inside the tank;
  • an overflow system;
  • a quick-mount base;
  • ...

Classiquement, le bouton poussoir est monté dans un corps creux 2, à l'intérieur duquel il est mobile en translation de haut en bas et inversement, selon un axe de poussée A, ce corps creux étant conçu pour être solidarisé sur le couvercle du réservoir. La fixation du corps creux au couvercle du réservoir peut être obtenue selon tous moyens appropriés et notamment à l'aide d'un système à contre-écrou 20, le couvercle du réservoir étant serré entre le contre-écrou 20 et une bague 21 du corps creux.Conventionally, the push button is mounted in a hollow body 2, inside which it is movable in translation from top to bottom and vice versa, along a thrust axis A, this hollow body being designed to be secured to the cover of the tank. . The fixing of the hollow body to the tank cover can be obtained by any appropriate means and in particular using a lock nut system 20, the tank cover being clamped between the lock nut 20 and a ring 21 of the body hollow.

De plus, dans le cadre de l'invention, le dispositif de commande comprend un organe sélecteur monté mobile en rotation autour de l'axe de poussée A, l'utilisateur étant à même de faire tourner l'organe sélecteur autour de l'axe A pour l'amener dans une position correspondante à un volume de chasse de son choix.In addition, in the context of the invention, the control device comprises a selector member mounted movable in rotation about the thrust axis A, the user being able to rotate the selector member around the axis A to bring it into a position corresponding to a flush volume of its choice.

En référence aux deux variantes de réalisation qui vont être décrites par la suite, l'organe sélecteur prend la forme d'une cuve 3 montée à l'intérieur du corps creux 2 de façon à pouvoir être mobile en rotation autour de l'axe de poussée A. On note à cet effet que le corps creux et la cuve sont conçus de façon à présenter des surfaces de contact mutuelles de forme cylindrique.With reference to the two alternative embodiments which will be described later, the selector member takes the form of a tank 3 mounted inside the hollow body 2 so as to be able to be movable in rotation about the axis of thrust A. To this end, it is noted that the hollow body and the tank are designed so as to have mutual contact surfaces of cylindrical shape.

De plus, le bouton poussoir est monté mobile en translation selon l'axe de poussée A à l'intérieur de la cuve, un ressort de rappel 4 étant intercalé entre le bouton poussoir et la cuve formée par l'organe sélecteur (ou entre le bouton et le corps creux si le fond de la cuve permet au ressort de prendre appui sur le fond du corps creux) pour ramener le bouton poussoir en position d'attente (figures 2 et 9). En d'autres termes, lors de l'actionnement (poussée vers le bas) du bouton poussoir, le ressort de rappel 4 est comprimé (figures 3, 4 et 12) et tend donc, une fois l'appui sur le bouton relâché, à repousser le bouton poussoir vers le haut, jusqu'à sa position d'attente.In addition, the push button is mounted movable in translation along the thrust axis A inside the tank, a return spring 4 being interposed between the push button and the tank formed by the selector member (or between the button and the hollow body if the bottom of the tank allows the spring to rest on the bottom of the hollow body) to return the push button to the standby position ( figures 2 and 9 ). In other words, when the push button is actuated (pushed down), the return spring 4 is compressed ( figures 3, 4 and 12 ) and therefore tends, once the button is released, to push the push button upwards to its standby position.

Par ailleurs, le dispositif de commande comprend :

  • un corps creux 2, présentant une bague 21 d'appui sur la face externe du couvercle du réservoir, un contre-écrou 20 étant destiné à être vissé sur le filetage 200 du corps creux pour venir serrer le couvercle entre la bague 21 et le contre-écrou 20 ;
  • un bouton poussoir comprenant :
    • un organe de liaison 10 destiné à relier le bouton poussoir au mécanisme de chasse (non représenté) monté dans le réservoir ;
    • au moins une butée 11, et en l'occurrence une paire de butées 11 positionnées de part et d'autre de l'organe de liaison.
Furthermore, the control device comprises:
  • a hollow body 2, having a ring 21 for bearing on the external face of the tank cover, a lock nut 20 being intended to be screwed onto the thread 200 of the hollow body in order to tighten the cover between the ring 21 and the counter nut 20;
  • a push button comprising:
    • a connecting member 10 intended to connect the push button to the flushing mechanism (not shown) mounted in the tank;
    • at least one stop 11, and in this case a pair of stops 11 positioned on either side of the connecting member.

Selon le principe de l'invention, l'organe sélecteur est mobile en rotation entre au moins deux positions qui vont être décrites plus en détails par la suite en référence aux deux variantes de réalisation explicitées par la suite :

  • une position autorisant l'engagement de la butée au travers de l'ouverture secondaire du fond (figures 4, 7, 10, 11 et 12) ;
  • une position bloquant l'engagement de la butée au travers de l'ouverture secondaire du fond (figures 2, 3, 5, 6 et 9).
According to the principle of the invention, the selector member is movable in rotation between at least two positions which will be described in more detail below with reference to the two alternative embodiments explained below:
  • a position authorizing the engagement of the stopper through the secondary opening of the bottom ( figures 4 , 7 , 10, 11 and 12 );
  • a position blocking the engagement of the stopper through the secondary opening of the bottom ( figures 2, 3 , 5, 6 and 9 ).

Pour actionner cet organe sélecteur, l'utilisateur peut agir sur une partie manipulable 30 présentée en partie supérieure du corps creux, et plus particulièrement en agissant sur une excroissance 300 facilitant la préhension et/ou l'entraînement en rotation de la partie manipulable.To activate this selector member, the user can act on a manipulable part 30 presented in the upper part of the hollow body, and more particularly by acting on a protrusion 300 facilitating the gripping and / or driving in rotation of the manipulable part.

Plus précisément, la partie manipulable 30 prend la forme d'une collerette s'étendant en partie supérieure de la cuve, et constituant une extrémité de la cuve.More specifically, the manipulable part 30 takes the form of a flange extending in the upper part of the tank, and constituting one end of the tank.

En outre, la partie manipulable est guidée en rotation sur le corps creux. Pour cela, l'extrémité supérieure du corps creux présente un rail annulaire 23 et la partie manipulable 30 présente sur sa face inférieure une gorge annulaire 301 ajustée à la forme du rail de telle sorte que le rail annulaire 23 puisse coulisser dans la gorge annulaire 301 en formant une liaison glissière.In addition, the manipulable part is guided in rotation on the hollow body. For this, the upper end of the hollow body has an annular rail 23 and the manipulable part 30 has on its underside an annular groove 301 adjusted to the shape of the rail so that the annular rail 23 can slide in the annular groove 301 by forming a slide link.

On note de plus que la partie manipulable présente un rebord périphérique 302 présentant un bourrelet interne 303 dont le diamètre est légèrement inférieur au diamètre externe du rail. Ainsi, le montage de la partie manipulable sur le corps creux s'effectue en enfonçant légèrement à force la partie manipulable sur le corps creux, de façon à forcer le passage du bourrelet interne sur le rail annulaire, tout en conservant la liberté en rotation de la partie manipulable sur le corps creux.It is further noted that the manipulable part has a peripheral rim 302 having an internal bead 303 whose diameter is slightly less than the external diameter of the rail. Thus, the assembly of the manipulable part on the hollow body is effected by slightly pressing the manipulable part on the hollow body, so as to force the passage of the internal bead on the annular rail, while retaining the freedom in rotation of the part that can be handled on the hollow body.

En référence à la figure 13, le bouton poussoir présente une interface de poussée 12 présentant un indicateur 120, la partie manipulable 30 de l'organe sélecteur portant au moins deux repères 306 de choix de volume de chasse, destinés à être placés en correspondance avec l'indicateur. En d'autres termes, l'utilisateur tourne la partie manipulable pour amener l'un des repères en face de l'indicateur 120 en vue de choisir, en fonction de l'illustration procurée par les repères, le volume de chasse avant d'actionner le bouton poussoir en appuyant sur l'interface de poussée de celui-ci.With reference to the figure 13 , the push button has a push interface 12 having an indicator 120, the manipulable part 30 of the selector member carrying at least two marks 306 for choosing the flush volume, intended to be placed in correspondence with the indicator. In other words, the user turns the manipulable part to bring one of the marks in front of the indicator 120 in order to choose, according to the illustration provided by the marks, the flush volume before press the push button by pressing on the push interface.

Tel qu'illustré par les figures 2 à 7, le corps creux comprend un fond 22 présentant quant à lui :

  • une ouverture principale 220, formant passage pour l'organe de liaison 10, et permettant son déplacement d'une position d'attente telle qu'illustrée par les figures 2 et 5 à une position de chasse (petite ou grande) telle qu'illustré par les figures 3, 4, 6 et 7 ;
  • au moins une ouverture secondaire et en l'occurrence deux ouverture secondaires 221, formant passage pour les butées 11.
As illustrated by figures 2 to 7 , the hollow body comprises a bottom 22 having for its part:
  • a main opening 220, forming a passage for the connecting member 10, and allowing its displacement from a waiting position as illustrated by figures 2 and 5 to a hunting position (small or large) as illustrated by the figures 3, 4 , 6 and 7 ;
  • at least one secondary opening and in this case two secondary opening 221, forming a passage for the stops 11.

Selon une première variante de réalisation illustrée par les figures 1 à 7, les butées 11 prennent la forme de montants cylindriques, et les ouvertures secondaires 221 sont circulaires, avec un diamètre égal, au jeu près, au diamètre des montants cylindriques. En outre, les ouvertures secondaires 221 sont ménagées de part et d'autre de l'ouverture principale 220 et positionnées de façon à pouvoir être traversées simultanément par les deux butées11.According to a first alternative embodiment illustrated by Figures 1 to 7 , the stops 11 take the form of cylindrical uprights, and the secondary openings 221 are circular, with a diameter equal, apart from play, to the diameter of the cylindrical uprights. In addition, the secondary openings 221 are formed on either side of the main opening 220 and positioned so that they can be traversed simultaneously by the two stops11.

L'organe sélecteur prend la forme, dans le cadre de la présente variante de réalisation, d'une cuve dont le fond constitue une partie obturatrice 304 intercalée entre le bouton poussoir et le corps creux. Cette partie obturatrice présente au moins un passage 305, et dans le cas illustré par les figures 2 à 7, deux passages 305 aptes à être placés en coïncidence avec les ouvertures secondaires 221, c'est-à-dire dans l'alignement des ouvertures secondaires, pour autoriser l'engagement des butées 11 au travers des ouvertures secondaires (en passant donc pas les passages 305).The selector member takes the form, in the context of the present embodiment, of a tank, the bottom of which constitutes a shutter portion 304 interposed between the push button and the hollow body. This obturating part has at least one passage 305, and in the case illustrated by the figures 2 to 7 , two passages 305 able to be placed in coincidence with the secondary openings 221, that is to say in alignment with the secondary openings, to allow the engagement of the stops 11 through the secondary openings (therefore passing the passages 305).

Selon la variante de réalisation qui vient d'être décrite, si la partie manipulable est tournée de façon à amener le repère « petite chasse » en face de l'indicateur porté par le bouton poussoir, les passages 305 du fond de la cuve sont décalées angulairement par rapport aux ouvertures secondaire du corps creux. Dans ce cas, lors d'une poussée sur le bouton poussoirs, les butées constituées par les montants cylindriques du bouton poussoir, viennent en arrêt contre la partie obturatrice (le fond de la cuve) et l'organe de liaison ne sort du corps creux que sur une partie de sa hauteur (figures 3 et 6).According to the variant embodiment which has just been described, if the manipulable part is turned so as to bring the “small flush” mark opposite the indicator carried by the push button, the passages 305 from the bottom of the tank are offset angularly with respect to the secondary openings of the hollow body. In this case, during a push on the push button, the stops constituted by the cylindrical uprights of the push button, come to a stop against the obturating part (the bottom of the tank) and the connecting member does not leave the hollow body that over part of its height ( figures 3 and 6 ).

En revanche, si la partie manipulable est tournée de façon à amener le repère « grande chasse » en face de l'indicateur porté par le bouton poussoir, les passages 305 du fond de la cuve sont alignés avec les ouvertures secondaire du corps creux. Dans ce cas, lors d'une poussée sur le bouton poussoirs, les butées constituées par les montants cylindriques du bouton poussoir, passent au travers des passages 305 et des ouvertures secondaires (figures 4 et 7), permettant la poursuite de la descente du bouton poussoir, de telle sorte que l'organe de liaison 10 sort du corps creux sur la quasi-totalité de sa hauteur.On the other hand, if the manipulable part is turned so as to bring the “big game” mark in front of the indicator carried by the push button, the passages 305 at the bottom of the tank are aligned with the secondary openings of the hollow body. In this case, during a push on the push button, the stops constituted by the cylindrical uprights of the push button, pass through passages 305 and secondary openings ( figures 4 and 7 ), allowing the descent of the push button to continue, so that the connecting member 10 leaves the hollow body over almost its entire height.

Selon une deuxième variante de réalisation illustrée par les figures 8 à 11, le bouton poussoir porte deux butées 11 s'étendant angulairement autour de l'axe de poussée A, tandis que le fond du corps creux présentent des ouvertures secondaires 221 s'étendant angulairement de façon à pouvoir être traversées par les butées.According to a second alternative embodiment illustrated by figures 8 to 11 , the push button carries two stops 11 extending angularly around the thrust axis A, while the bottom of the hollow body have secondary openings 221 extending angularly so that they can be crossed by the stops.

Comme dans le cas de la première variante de réalisation, l'organe sélecteur prend la forme, dans le cadre de la présente variante de réalisation, d'une cuve 3 dont le fond constitue une partie obturatrice intercalée entre le bouton poussoir et le corps creux. Cette partie obturatrice présente au moins un passage, et dans le cas illustré par les figure 8 à 11, deux passages aptes à être placés en coïncidence avec les ouvertures secondaires 221, c'est-à-dire dans l'alignement des ouvertures secondaires, pour autoriser l'engagement des butées 11 au travers des ouvertures secondaires.As in the case of the first embodiment, the selector member takes the form, in the context of the present embodiment, of a tank 3, the bottom of which constitutes a shutter part interposed between the push button and the hollow body. . This obturating part has at least one passage, and in the case illustrated by the figure 8 to 11 , two passages able to be placed in coincidence with the secondary openings 221, that is to say in alignment with the secondary openings, to allow the engagement of the stops 11 through the secondary openings.

Selon une spécificité de cette deuxième variante de réalisation, les butées présentent au moins deux crans angulaires 110, 111, dont l'un bas, le cran 110, et l'autre haut, le cran 111 (avec dans le cas présent un cran intermédiaire 112), les ouvertures secondaires s'étendant angulairement de façon à pouvoir être traversées, en fonction de la position de l'organe sélecteur, par :

  • le cran bas 110 (figure 10), tandis que le cran intermédiaire 112 vient en butée contre la partie obturatrice constituée par le fond de la cuve 3, ou ;
  • le cran bas 110 et le cran intermédiaire 112 ensemble (figure 11), tandis que le cran haut 111 vient en butée contre la partie obturatrice, ou ;
  • par le cran bas 110 et le cran haut 111 ensemble (y inclus le cran intermédiaire 112 dans le cas présent).
According to a specific feature of this second alternative embodiment, the stops have at least two angular notches 110, 111, one of which is bottom, the notch 110, and the other top, the notch 111 (with in this case an intermediate notch 112), the secondary openings extending angularly so that they can be traversed, depending on the position of the selector member, by:
  • low notch 110 ( figure 10 ), while the intermediate notch 112 abuts against the shutter part formed by the bottom of the tank 3, or;
  • the bottom notch 110 and the intermediate notch 112 together ( figure 11 ), while the high notch 111 abuts against the obturating part, or;
  • by the bottom notch 110 and the top notch 111 together (including the intermediate notch 112 in this case).

On comprend que l'on peut augmenter ainsi le nombre de possibilités de volumes de chasse, en fonction du nombre de crans des butées du bouton poussoir.It is understood that one can thus increase the number of possibilities of flush volumes, depending on the number of notches of the push button stops.

Selon encore d'autres variantes de réalisation envisageables (non représentées), l'organe sélecteur peut être constitué :

  • par le bouton poussoir lui-même, mobile en rotation par rapport au corps creux, par exemple en étant monté mobile en translation et en rotation directement à l'intérieur du corps creux ;
  • par le corps creux lui-même, monté mobile en rotation par rapport au bouton poussoir.
According to yet other possible embodiments (not shown), the selector member can be made up:
  • by the push button itself, movable in rotation relative to the hollow body, for example by being mounted movable in translation and in rotation directly inside the hollow body;
  • by the hollow body itself, mounted movable in rotation relative to the push button.
