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 toilet water tank, this frame comprising a means for closing a hole in a lower wall. (Bottom) of the tank and through which the water tank can be discharged, these shutter means being connected by a transmission mechanism to actuating 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 rather old approach, these actuating means may 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 the evacuation water from the tank. Thus, clearly, by moving the pull tab up, it also causes upward movement of the closing means of the flush and, conversely, by releasing the pull tab, the latter, and the shutter means move. downwards until the closure means resume their closed position of the orifice formed in the bottom wall of the tank.

Une telle solution est particulièrement fiable. Cependant, on retrouve un élément qui fait saillie en dehors du réservoir et qui doit être tiré complétement pour déclencher complétement une chasse d'eau.Such a solution is particularly reliable. However, there is an element that protrudes outside the tank and must be pulled completely to trigger a complete flush.

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 oeuvre 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 approach, however, which is already widely used, the actuating means consist of a push button (or two push buttons, one to release a "big hunt" and the other to release a "small hunt"") Presented on a top wall (in practice the lid) of the tank, so that the user must push the push button to the inside of the tank to cause a flush. Of course, in this case, it is necessary to implement a system that reverses the stroke of the push button at the closure means, so that a downward movement of the push button or buttons result in a upward movement of the shutter means, while 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 (opposée à la première extrémité par rapport à l'axe de pivotement) est reliée aux moyens d'obturation.To achieve this, a lever-operated reversing system is mounted inside the tank, this lever being pivotally mounted about an axis carried either by the frame of the flush 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 relative to the pivot axis) is connected to the closure means.

Des mécanismes à bouton poussoir sont décrits notamment dans les documents de brevets publiés sous les numéros FR2719858 et FR3031527 .Push button mechanisms are described in particular in the patent documents published under the numbers FR2719858 and FR3031527 .

De tels mécanismes donnent globalement satisfaction et s'avèrent relativement fiable.Such mechanisms are generally satisfactory and relatively reliable.

Suivant un inconvénient commun des moyens d'actionnement de type tirette et de type bouton poussoir, il a été constaté que de mauvaises manipulations pouvaient entraîner des pertes d'eaux non désirables. Par exemple, des enfants peuvent jouer avec un bouton poussoir en l'enfonçant légèrement de manière à laisser couler un filet d'eau. Dans ce cas, le réservoir se remplit en même temps que de l'eau est gaspillée.According to a common drawback of the pull-type and push-button actuation means, it has been found that improper handling can lead to undesirable water losses. For example, children can play with a push button by pushing it slightly so that a trickle of water flows. In this case, the tank fills up at the same time as water is wasted.

Selon un inconvénient propre aux moyens d'actionnement du type à bouton poussoir, le réglage du mécanisme de chasse d'eau peut s'avérer plus complexe que celui des mécanismes utilisant des moyens d'actionnement constitués par une tirette. En effet, alors qu'avec une tirette il existe un rapport égal à 1 entre la course de la tirette et la course des moyens d'obturation de la chasse, un mécanisme utilisant un bouton poussoir et un système inverseur à levier implique en général un rapport égal à environ 3 entre la course du bouton poussoir et la course des moyens d'obturation. Cette augmentation du rapport oblige une personne réalisant l'assemblage du mécanisme de chasse à affiner précisément le réglage du mécanisme.According to a disadvantage specific to the actuating means of the push button type, the setting of the flush mechanism may be more complex than that of mechanisms using actuating means constituted by a pull tab. Indeed, while with a zipper there is a ratio of 1 between the race of the zipper and the stroke of the closing means of the hunt, a mechanism using a button pusher and a toggle lever system generally involves a ratio of about 3 between the stroke of the push button and the stroke of the closure means. This increase in the ratio requires a person performing the assembly of the hunting mechanism to precisely refine the adjustment of the mechanism.

Selon un autre inconvénient pouvant résulter de ce déréglage ou de la manière dont est actionné le bouton poussoir, on peut remarquer que le volume d'eau chassé peut ne pas être constant.According to another disadvantage that may result from this maladjustment or the manner in which the push button is actuated, it may be noted that the volume of water displaced may not be constant.

La problématique du volume d'eau stocké dans le réservoir est particulièrement importante du fait que des réglementations strictes peuvent définir des seuils à respecter. En conséquence, les mécanismes de chasse d'eau doivent être particulièrement fiables à ce sujet.The problem of the volume of water stored in the tank is particularly important because strict regulations can set thresholds to be respected. As a result, the flush mechanisms must be particularly reliable in this regard.

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

Plus précisément, l'invention a pour objectif de proposer un mécanisme de chasse d'eau du type à bouton poussoir qui permet d'éviter ou à tout le moins de limiter le risque de gaspillage d'eau suite à des manipulations indésirables du bouton poussoir.More specifically, the object of the invention is to propose a flush mechanism of the push-button type that makes it possible to avoid or at least limit the risk of wasting water as a result of unwanted manipulations of the push button. .

L'invention a également pour objectif de proposer un tel mécanisme de chasse d'eau qui soit fiable dans le temps, aussi bien dans son fonctionnement que dans sa capacité à stocker un volume d'eau prédéterminé, et ce notamment en comparaison des solutions proposées par l'art antérieur.The invention also aims to provide such a flushing mechanism that is reliable over time, both in its operation as in its ability to store a predetermined volume of water, and in particular in comparison with the proposed solutions by the prior art.

L'invention a encore pour objectif de proposer un tel mécanisme de chasse d'eau qui soit aisé à installer et notamment à régler lors de ladite installation.The invention also aims to provide such a flush mechanism that is easy to install and in particular to adjust during said installation.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite sont atteints grâce à l'invention qui a pour objet un mécanisme de chasse d'eau destiné à être monté dans un réservoir d'eau de toilettes, comprenant :

  • au moins un bouton poussoir destiné à être présenté sur le réservoir, mobile entre une position de repos et au moins une position enfoncée, le bouton poussoir comportant des moyens de rappel en position de repos ;
  • un bâti destiné à être monté à l'intérieur du réservoir et comprenant des moyens d'obturation mobiles entre une position d'obturation et au moins une position de libération d'un orifice de passage d'eau ménagé dans une paroi du réservoir ;
  • un mécanisme de transmission entre le ou les boutons poussoirs et les moyens d'obturation ;
caractérisé en ce que le bouton poussoir est libre en translation par rapport au mécanisme de transmission, à partir de la position de repos jusqu'à au moins une position enfoncée prédéterminée de couplage transitoire avec le mécanisme de transmission dans laquelle le bouton poussoir et le mécanisme de transmission sont solidaires en translation, le passage du bouton poussoir d'une position enfoncée prédéterminée de couplage transitoire à la position de repos entraînant le passage des moyens d'obturation de la position d'obturation à une position de libération.These objectives, as well as others that will appear later are achieved through the invention which relates to a flush mechanism for mounting in a toilet water tank, comprising:
  • at least one push button intended to be presented on the reservoir, movable between a rest position and at least one depressed position, the push button comprising return means in the rest position;
  • a frame intended to be mounted inside the tank and comprising closing means movable between a closed position and at least one release position of a water passage orifice formed in a wall of the tank;
  • a transmission mechanism between the one or more pushbuttons and the shutter means;
characterized in that the push button is free in translation with respect to the transmission mechanism, from the rest position to at least one predetermined depressed transient coupling position with the transmission mechanism in which the push button and the mechanism transmission are integral in translation, the passage of the push button from a predetermined transient coupling transient position to the rest position causing the passage of the shutter means from the closed position to a release position.

Le mécanisme de chasse d'eau selon l'invention permet d'éviter des gaspillages d'eau faisant suite à des manipulations indésirables du bouton poussoir.The flushing mechanism according to the invention makes it possible to avoid waste of water following undesired manipulations of the push button.

En effet, grâce à sa conception, une chasse d'eau peut être déclenchée uniquement à partir du moment où le bouton poussoir a été enfoncé jusqu'à sa ou une de ses positions enfoncées prédéterminée de couplage transitoire. En conséquence, si le bouton est accidentellement enfoncé, ou enfoncé de manière incomplète, sans que la ou les positions enfoncées prédéterminées de couplage transitoire soient atteintes, alors les moyens d'obturation restent en position d'obturation et l'eau stockée dans le réservoir n'est pas gaspillée.Indeed, thanks to its design, a flush can be triggered only from the moment the push button has been pressed to its or one of its predetermined transient coupling positions. Consequently, if the button is accidentally depressed, or pressed in an incomplete manner, without the predetermined transient coupling position (s) being reached, then the sealing means remain in the closed position and the water stored in the reservoir is not wasted.

De manière complémentaire, le passage des moyens d'obturation de la position d'obturation à une position de libération résulte du passage du bouton poussoir d'une position enfoncée prédéterminée de couplage transitoire à la position de repos. De ce fait, le passage des moyens d'obturation de la position d'obturation à une position de libération résulte de l'action des moyens de rappel en position de repos du bouton poussoir. Cette conception permet de contrôler la force qui est exercée pour faire passer les moyens d'obturation de leur position d'obturation à une de leur position de libération. En conséquence, la fiabilité du mécanisme dans le temps est améliorée.In a complementary manner, the passage of the shutter means from the shutter position to a release position results from the passage of the push button from a predetermined transient coupling position to the rest position. As a result, the passage of the closure means from the closed position to a release position results from the action of the return means in the rest position of the push button. This design makes it possible to control the force that is exerted to move the sealing means from their closed position to one of their release position. As a result, the reliability of the mechanism over time is improved.

Egalement, grâce à l'action directe du mécanisme (ouverture des moyens d'obturation grâce à la remontée du bouton poussoir) et contrairement à un mécanisme employant un système inverseur à levier, le mécanisme permet de garantir que le réservoir se remplit d'un volume prédéterminé d'eau.Also, thanks to the direct action of the mechanism (opening of the shutter means through the raising of the push button) and unlike a mechanism employing a toggle lever system, the mechanism ensures that the tank fills with a predetermined volume of water.

Selon un mode de réalisation préférentiel, le mécanisme de transmission comprend au moins une tige de traction mobile en translation entre une position non-tractée et au moins une position tractée, le passage de la tige de traction de sa position non-tractée à une position tractée entraînant le passage des moyens d'obturation de la position d'obturation à une position de libération, et le mécanisme de transmission comporte des moyens de couplage transitoire de la tige de traction au bouton poussoir, les moyens de couplage transitoire étant susceptibles de coupler ensemble la tige de traction au bouton poussoir en position enfoncée prédéterminée de couplage transitoire du bouton poussoir, et de découpler la tige de traction du bouton poussoir lors du retour du bouton poussoir à sa position de repos.According to a preferred embodiment, the transmission mechanism comprises at least one traction rod movable in translation between a non-towed position and at least one trailed position, the passage of the traction rod from its non-towed position to a position tethered driving the passage of the shutter means from the closed position to a release position, and the transmission mechanism comprises means for transient coupling of the pull rod to the push button, the transient coupling means being capable of coupling together the push rod to the push button in the depressed predetermined transient coupling position of the push button, and decouple the pull rod of the push button when returning the push button to its rest position.

Selon ce mode de réalisation, le mécanisme de chasse d'eau a un rapport égal à 1 entre la course de la tige de traction et la course des moyens d'obturation, permettant ainsi de simplifier le réglage et la fiabilité du mécanisme selon l'invention dans le temps.According to this embodiment, the flushing mechanism has a ratio equal to 1 between the travel of the traction rod and the stroke of the closure means, thus making it possible to simplify the adjustment and the reliability of the mechanism according to the invention. invention in time.

Selon un mode de réalisation avantageux, le mécanisme de chasse d'eau comprend :

  • un premier ensemble destiné à être monté sur un couvercle du réservoir, le premier ensemble comprenant :
    • le bouton poussoir ;
    • une première partie du mécanisme de transmission comprenant la tige de traction ;
  • un deuxième ensemble destiné à être monté dans le réservoir, séparément du premier ensemble, le deuxième ensemble comprenant :
    • le bâti ;
    • une deuxième partie du mécanisme de transmission, complémentaire de la première partie du mécanisme de transmission, couplée aux moyens d'obturation ;
et le mécanisme de transmission présente des moyens d'accouplement de la première partie du mécanisme de transmission à la deuxième partie du mécanisme de transmission lors d'un positionnement du couvercle sur le réservoir.According to an advantageous embodiment, the flushing mechanism comprises:
  • a first assembly for mounting on a tank lid, the first assembly comprising:
    • the push button;
    • a first part of the transmission mechanism comprising the pull rod;
  • a second assembly intended to be mounted in the reservoir, separately from the first assembly, the second assembly comprising:
    • the built ;
    • a second part of the transmission mechanism, complementary to the first part of the transmission mechanism, coupled to the closure means;
and the transmission mechanism has means for coupling the first portion of the transmission mechanism to the second portion of the transmission mechanism during positioning of the cover on the reservoir.

Une telle conception permet de simplifier grandement le réglage du mécanisme de chasse d'eau selon l'invention. En effet, il suffit alors à une personne qui réalise l'assemblage du mécanisme de monter le premier ensemble sur le couvercle du réservoir et le deuxième ensemble dans le réservoir pour que, lors de la mise en place du couvercle sur le réservoir, le réglage du mécanisme de chasse d'eau s'effectue de lui-même.Such a design greatly simplifies the setting of the flush mechanism according to the invention. Indeed, it is then enough for a person who carries out the assembly of the mechanism to mount the first assembly on the tank lid and the second assembly in the tank so that, when setting up the lid on the tank, the adjustment the flushing mechanism is self-cleaning.

Avantageusement, le premier ensemble comprend des moyens de verrouillage de la tige de traction dans une position non-tractée verrouillée, les moyens d'accouplement interagissant ensemble lors du positionnement du couvercle sur le réservoir tandis que la tige de traction est dans la position non-tractée verrouillée et que les moyens d'obturation sont en position d'obturation.Advantageously, the first assembly comprises means for locking the traction rod in a non-towed locked position, the coupling means interacting together during the positioning of the lid on the tank while the pulling rod is in the non-locked position. trailed locked and that the closure means are in the closed position.

Selon cette conception, le réglage du mécanisme de chasse d'eau s'effectue alors que la tige de traction est dans une position non-tractée verrouillée. Par la suite, il suffit à une personne de déverrouiller la tige de traction de sa position non-tractée verrouillée pour que le mécanisme selon l'invention soit opérationnel.According to this design, the flush mechanism is adjusted while the pull rod is in a locked non-tow position. Thereafter, it is sufficient for a person to unlock the pull rod from its locked non-towed position so that the mechanism according to the invention is operational.

Préférentiellement, le mécanisme de transmission comporte au moins une butée de découplage coopérant avec les moyens de couplage transitoire dans la position de repos du bouton poussoir.Preferably, the transmission mechanism comprises at least one decoupling abutment cooperating with the transient coupling means in the rest position of the push button.

Une telle butée de découplage forme un moyen simple et fiable permettant de découpler une tige de traction du bouton poussoir quand ce dernier a atteint sa position de repos et pour permettre le retour de la tige de traction à une position non-tractée.Such a decoupling abutment forms a simple and reliable means for decoupling a pull rod of the push button when the latter has reached its rest position and to allow the return of the pull rod to a non-towed position.

Avantageusement, les moyens de couplage transitoire comportent :

  • un organe mobile d'accrochage de la tige de traction avec le bouton poussoir, susceptible de coopérer avec la butée de découplage ;
  • des moyens de mise en tension élastique de l'organe mobile d'accrochage tendant à déclencher l'accrochage de la tige de traction avec le bouton poussoir.
Advantageously, the transient coupling means comprise:
  • a movable member for hooking the pull rod with the push button, capable of cooperating with the decoupling stop;
  • means for elastic tensioning of the movable fastening member tending to trigger the attachment of the pull rod with the push button.

Selon une solution préférentielle, les moyens de couplage transitoire comportent au moins un cran, l'organe mobile d'accrochage étant destiné à s'accrocher avec le cran pour coupler la tige de traction au bouton poussoir.According to a preferred solution, the transient coupling means comprise at least one notch, the mobile attachment member being intended to hook with the notch to couple the pull rod to the push button.

Grâce à ces moyens de couplage transitoire, à leurs moyens de mise en tension élastique et au cran, le cran est accroché automatiquement par l'organe mobile dès lors que le bouton poussoir est enfoncé jusqu'à une profondeur suffisante, cette hauteur étant prédéfinie et formant alors la position enfoncée prédéterminée de couplage transitoire du mécanisme de transmission avec le bouton poussoir.Thanks to these transient coupling means, their elastic tensioning means and the notch, the notch is hooked automatically by the movable member when the push button is depressed to a sufficient depth, this height being predefined and then forming the predetermined transient transient coupling position of the transmission mechanism with the push button.

Selon une caractéristique préférentielle, les moyens de couplage transitoire comportent au moins deux crans successifs, chaque cran représentant une quantité d'eau prédéterminée d'eau à chasser du réservoir d'eau de toilette.According to a preferred feature, the transient coupling means comprise at least two successive notches, each notch representing a predetermined quantity of water of water to be removed from the toilet tank.

Le mécanisme de chasse d'eau présente alors une « grande chasse » et une « petite chasse » qui correspondent à au moins deux profondeurs différentes d'enfoncement du bouton poussoir.The flush mechanism then has a "big hunt" and a "small hunt" that correspond to at least two different depths of depression of the push button.

Selon un mode de réalisation envisageable, le bouton poussoir comporte deux parties dont :

  • une partie permet d'atteindre une première position enfoncée prédéterminée de couplage transitoire correspondant à la petite chasse, où un premier cran permet de réaliser le couplage transitoire, et
  • l'autre partie permet d'atteindre une deuxième position enfoncée prédéterminée de couplage transitoire (après avoir franchi la première position enfoncée prédéterminée de couplage transitoire et le premier cran) correspondant à la grande chasse et où un deuxième cran permet de réaliser également le couplage transitoire.
According to one conceivable embodiment, the push button comprises two parts, of which:
  • a part makes it possible to reach a first predetermined transient coupling transient position corresponding to the small hunting, where a first notch makes it possible to carry out the transient coupling, and
  • the other part makes it possible to reach a second predetermined depressed position of transient coupling (after having crossed the first transient predetermined transient coupling position and the first notch) corresponding to the large hunting and where a second notch also makes it possible to perform the transient coupling .

Selon un mode de réalisation préféré, la tige de traction présente le ou les crans et en ce que le bouton poussoir porte l'organe mobile d'accrochage.According to a preferred embodiment, the pull rod has the one or more notches and in that the push button carries the movable hooking member.

Un tel mode de réalisation présente une conception plus aisée à produire, s'agissant en particulier du montage de l'organe mobile d'accrochage sur le bouton poussoir.Such an embodiment has a design easier to produce, particularly with regard to the mounting of the movable fastening member on the push button.

Selon une solution avantageuse, le mécanisme de chasse d'eau comporte un corps récepteur présentant une cavité dans laquelle le bouton poussoir est monté mobile, les moyens de rappel comportant au moins un ressort de compression situé à l'intérieur de la cavité, le ressort de compression étant destiné à être comprimé par le bouton poussoir lors de son passage de sa position de repos à une position enfoncée.According to an advantageous solution, the flushing mechanism comprises a receiver body having a cavity in which the push button is movably mounted, the return means comprising at least one compression spring located inside the cavity, the spring compression being intended to be compressed by the push button during its passage from its rest position to a depressed position.

Le corps récepteur, ainsi que le ou les ressorts de compression, sont des moyens simples à mettre en oeuvre pour assurer le guidage du bouton poussoir de sa position de repos à l'une de ses positions enfoncées et inversement, ainsi qu'à assurer la capacité du mécanisme à appliquer une force constante pour entraîner le passage des moyens d'obturation de la position d'obturation à l'une des positions de libération.The receiving body, as well as the compression spring or springs, are simple means to implement to ensure the guidance of the push button from its rest position to one of its depressed positions and vice versa, as well as to ensure the ability of the mechanism to apply a constant force to cause the passage of the shutter means from the closed position to one of the release positions.

Préférentiellement, le corps récepteur présente la butée de découplage.Preferably, the receiver body has the decoupling stop.

Cette conception permet d'assurer le désaccouplement de la tige de traction au bouton poussoir au moment où le bouton poussoir atteint sa position de repos dans le corps récepteur.This design ensures disengagement of the pull rod to the push button at the moment the push button reaches its rest position in the receiving body.

Tel que l'on peut l'observer sur les figures 1 à 3, le mécanisme de chasse d'eau selon l'invention équipe un réservoir 1 d'eau de toilettes. Ce mécanisme comprend au moins un bouton poussoir 2, un bâti 3 comprenant des moyens d'obturation 30 d'un orifice de passage d'eau ménagé dans une paroi du réservoir, et un mécanisme de transmission 4 couplant le bouton poussoir aux moyens d'obturation.As can be seen from the Figures 1 to 3 , the flush mechanism according to the invention equips a tank 1 of toilet water. This mechanism comprises at least one push button 2, a frame 3 comprising means 30 for closing a water passage opening in a wall of the tank, and a transmission mechanism 4 coupling the push button to the means of shutter.

Le bouton poussoir 2 est monté sur un couvercle du réservoir. Ce bouton poussoir 2 est mobile à l'intérieur d'une cavité 220 d'un corps récepteur 22. Le bouton poussoir est mobile entre une position de repos (figure 1) et des positions enfoncées, dont au moins une position enfoncée prédéterminée de couplage transitoire avec le mécanisme de transmission (figure 2).The push button 2 is mounted on a tank lid. This push button 2 is movable inside a cavity 220 of a receiver body 22. The push button is movable between a rest position ( figure 1 ) and depressed positions, including at least one predetermined transient coupling transient position with the transmission mechanism ( figure 2 ).

Tel que représenté sur la figure 3, le bouton poussoir est en cours de remontée, depuis une position enfoncée prédéterminée de couplage transitoire, et a quasiment atteint sa position de repos.As shown on the figure 3 , the push button is being wound up from a predetermined transient coupling position and has almost reached its rest position.

Le bouton poussoir comporte notamment des moyens de rappel 5 en position de repos. Ces moyens de rappel prennent la forme d'un ressort de compression 50 situé à l'intérieur de la cavité 220, sous le bouton poussoir (figure 4). Le ressort de compression est notamment destiné à être comprimé par le bouton poussoir lors de son passage d'une position de repos à une position enfoncée, et tend donc à faire remonter le bouton poussoir jusqu'à sa position de repos.The push button comprises in particular restoring means 5 in the rest position. These return means take the form of a compression spring 50 located inside the cavity 220, under the push button ( figure 4 ). The compression spring is especially intended to be compressed by the push button during its passage from a rest position to a depressed position, and therefore tends to raise the push button to its rest position.

Le bâti 3 est quant à lui monté à l'intérieur du réservoir, au-dessus de l'orifice de passage d'eau ménagé dans la paroi inférieur du réservoir. Les moyens d'obturation 30 présentés par le bâti sont mobiles entre une position d'obturation (figures 1 et 2) et au moins une position de libération (figure 3) de l'orifice.The frame 3 is in turn mounted inside the tank, above the water passage opening in the bottom wall of the tank. The closure means 30 presented by the frame are movable between a closed position ( Figures 1 and 2 ) and at least one release position ( figure 3 ) of the orifice.

Grâce au mécanisme de transmission du mécanisme de chasse d'eau selon l'invention, on remarque que quand le bouton poussoir est dans sa position de repos ou dans une de ses positions enfoncées (sans avoir atteint une position enfoncée prédéterminée de couplage transitoire), les moyens d'obturation restent en position d'obturation. En effet, ce n'est que lors de la remontée du bouton poussoir d'une de ses positions enfoncées prédéterminées de couplage transitoire à sa position de repos que les moyens d'obturation passent dans une position de libération.Thanks to the transmission mechanism of the flush mechanism according to the invention, it is noted that when the push button is in its rest position or in one of its depressed positions (without having reached a predetermined transient coupling transient position), the sealing means remain in the closed position. Indeed, it is only when the push button is raised from one of its predetermined transient coupling transient positions to its rest position that the sealing means pass into a release position.

En conséquence, le mécanisme de transmission est conçu pour que :

  • le bouton poussoir soit libre en translation par rapport au mécanisme de transmission, à partir de la position de repos jusqu'à au moins une position enfoncée prédéterminée de couplage transitoire avec le mécanisme de transmission dans laquelle le bouton poussoir et le mécanisme de transmission sont solidaires en translation ;
  • le passage du bouton poussoir d'une position enfoncée prédéterminée de couplage transitoire à la position de repos entraînant le passage des moyens d'obturation de la position d'obturation à une position de libération.
As a result, the transmission mechanism is designed so that:
  • the push button is free in translation relative to the transmission mechanism, from the rest position to at least one predetermined transient coupling transient position with the transmission mechanism in which the push button and the transmission mechanism are integral in translation;
  • the passage of the push button from a predetermined transient coupling transient position to the rest position causing the passage of the shutter means from the shutter position to a release position.

Selon le présent mode de réalisation et tel que l'on peut l'observer sur les figures 1 à 4 ainsi que sur les figures 5a à 5g, le mécanisme de transmission 4 comprend une tige de traction 40 et des moyens de couplage transitoire de la tige de traction au bouton poussoir 2.According to the present embodiment and as can be seen on the Figures 1 to 4 as well as on Figures 5a to 5g , the transmission mechanism 4 comprises a traction rod 40 and means for transient coupling of the pull rod to the push button 2.

Cette tige de traction est mobile en translation entre une position non-tractée et au moins une position tractée.This traction rod is movable in translation between a non-towed position and at least one towed position.

Quand la tige de traction passe de sa position non-tractée à une position tractée, elle entraîne le passage des moyens d'obturation 30 de la position d'obturation à une position de libération.When the traction rod moves from its non-drawn position to a trailed position, it causes the closing means 30 to move from the closed position to a release position.

Tel qu'on peut l'observer sur la figure 4 et les figures 5a à 5g, le bouton poussoir 2 comporte une partie basse formant un logement 201 dans lequel la tige de traction 40 est susceptible de se loger (figures 5b à 5f).As can be seen on the figure 4 and the Figures 5a to 5g , the push button 2 comprises a lower part forming a housing 201 in which the pull rod 40 is able to be housed ( Figures 5b to 5f ).

Les moyens de couplage transitoire permettent de coupler ensemble la tige de traction au bouton poussoir en position enfoncée prédéterminée de couplage transitoire du bouton poussoir avec le mécanisme de transmission (la tige de traction), et de découpler la tige de traction du bouton poussoir lors du retour du bouton poussoir à sa position de repos.The transient coupling means are used to couple together the pull rod to the push button in the predetermined depressed transient coupling position of the push button with the transmission mechanism (the pull rod), and to decouple the push rod from the push button during the return of the push button to its rest position.

Les moyens de couplage transitoires sont décrits plus en détails ci-après en référence à la figure 4 et aux figures 5a à 5g.The transient coupling means are described in more detail below with reference to the figure 4 and to Figures 5a to 5g .

Dans un premier temps, on observe que les moyens de couplage transitoire comportent des crans 25. Ces crans sont portés par la tige de traction 40. On observe plus précisément au moins deux crans successifs positionnés sur la tige de traction 40. Ces crans ont des positions prédéterminées et sont destinés à permettre de chasser des quantités d'eau prédéterminées différentes du réservoir 1 d'eau de toilette, à savoir une « petite chasse » et une « grande chasse ».In a first step, it is observed that the transient coupling means comprise notches 25. These notches are carried by the pull rod 40. More precisely, at least two successive notches positioned on the pull rod 40 are observed. predetermined positions and are intended to allow to chase different predetermined amounts of water from the tank 1 toilet water, namely a "small hunt" and a "large hunt".

Dans un second temps, on observe que les moyens de couplage transitoire comportent un organe mobile d'accrochage 23 de la tige de traction 40 avec le bouton poussoir 2. Cet organe mobile d'accrochage est conçu pour s'accrocher avec les crans pour coupler la tige de traction 40 au bouton poussoir 2.In a second step, it is observed that the transient coupling means comprise a mobile attachment member 23 of the pull rod 40 with the push button 2. This mobile hooking member is designed to hook with the notches to couple the pull rod 40 to the push button 2.

Cet organe mobile d'accrochage est ainsi porté par le bouton poussoir 2. L'organe mobile d'accrochage est notamment couplé à la partie basse du bouton poussoir 2, qui présente des trous 202 complémentaires de tétons clipsables 232 portés par l'organe mobile d'accrochage.This mobile attachment member is thus carried by the push button 2. The mobile attachment member is in particular coupled to the lower part of the push button 2, which has holes 202 complementary snap pins 232 carried by the movable member hooking.

L'organe mobile d'accrochage comporte encore une partie d'accrochage 230 qui est destinée à coopérer avec les crans tel qu'illustré par les figures 5c et 5d.The mobile attachment member further comprises a hooking portion 230 which is intended to cooperate with the notches as illustrated by the Figures 5c and 5d .

Tel qu'on peut l'observer sur les figures 4, 5a, 5b, 5e, 5f et 5g, l'organe mobile d'accrochage comporte également une partie de découplage 231. Cette partie de découplage est notamment destinée à coopérer avec une butée de découplage.As can be seen from the figures 4 , 5a, 5b, 5e, 5f and 5g , the mobile attachment member also comprises a decoupling portion 231. This decoupling portion is in particular intended to cooperate with a decoupling abutment.

En effet, le mécanisme de transmission comporte une butée de découplage 221 coopérant avec les moyens de couplage transitoire dans la position de repos du bouton poussoir (figures 5a, 5f et 5g) ou quand le bouton poussoir va atteindre sa position de repos (figure 5e). Tel qu'on peut l'observer sur les figures 5a, 5b, 5e, 5f et 5g, cette butée de découplage 221 est présentée par le corps récepteur, et est notamment formée par la face inférieure du fond de la cavité 220.Indeed, the transmission mechanism comprises a decoupling stop 221 cooperating with the transient coupling means in the rest position of the push button ( Figures 5a, 5f and 5g ) or when the push button reaches its rest position ( figure 5e ). As can be seen from the FIGS. 5a, 5b, 5e, 5f and 5g this decoupling stop 221 is presented by the receiver body, and is formed in particular by the bottom face of the bottom of the cavity 220.

De manière complémentaire, les moyens de couplage transitoire comportent également des moyens de mise en tension élastique 24 de l'organe mobile d'accrochage 23. Ces moyens de mise en tension élastique tendent à déclencher l'accrochage de la tige de traction avec le bouton poussoir. Plus précisément, ces moyens de mise en tension élastique prennent la forme d'un ressort positionné sur une excroissance 240 présentée par la partie basse du bouton poussoir, le ressort étant emprisonné sous l'organe mobile d'accrochage.In a complementary manner, the transient coupling means also comprise means for elastic tensioning 24 of the mobile fastening member 23. These elastic tensioning means tend to trigger the attachment of the traction rod with the button. button. More specifically, these elastic tensioning means take the form of a spring positioned on a protrusion 240 presented by the lower part of the push button, the spring being trapped under the movable fastening member.

La cinématique de fonctionnement du bouton poussoir, en relation avec les figures 5a à 5g, est décrite ci-après.The operating kinematics of the push button, in relation to the Figures 5a to 5g , is described below.

Selon la figure 5a, le bouton poussoir 2 est dans une position de repos (ressort de compression 50 décomprimé) et la tige de traction 40 est dans une position non-tractée. Dans ce cas, on observe que la partie de découplage 231 de l'organe mobile d'accrochage 23 coopère avec la butée de découplage 221. Ainsi, l'organe mobile d'accrochage est retenu éloigné de la tige de traction et le bouton poussoir est libre en translation par rapport à la tige de traction. Cette situation correspond à la figure 1 dans laquelle les moyens d'obturation sont en position d'obturation.According to figure 5a , the push button 2 is in a rest position (decompressed compression spring 50) and the pull rod 40 is in a non-towed position. In this case, it is observed that the decoupling portion 231 of the movable fastening member 23 cooperates with the decoupling stop 221. Thus, the movable fastening member is held away from the pull rod and the push button is free in translation relative to the pull rod. This situation corresponds to the figure 1 in which the sealing means are in the closed position.

Selon la figure 5b, le bouton poussoir est enfoncé, mais il n'a pas atteint une position enfoncée prédéterminée de couplage transitoire et le bouton poussoir est toujours libre en translation par rapport à la tige de traction. On observe alors la compression du ressort de compression 50 et l'action des moyens de mise en tension élastique. Ces moyens de mise en tension élastique tendent à déclencher l'accrochage de la tige de traction avec le bouton poussoir en appliquant la partie d'accrochage 230 de l'organe mobile d'accrochage 23 contre la tige de traction 40.According to figure 5b , the push button is depressed, but it has not reached a predetermined transient coupling depressed position and the push button is still free in translation relative to the pull rod. The compression spring 50 and the action of the elastic tensioning means are then observed. These elastic tensioning means tend to trigger the attachment of the pull rod with the push button by applying the hooking portion 230 of the movable fastening member 23 against the pull rod 40.

Selon la figure 5c, le bouton poussoir est enfoncé et à atteint une position enfoncée prédéterminée de couplage transitoire. En effet, on observe que la partie d'accrochage 230 de l'organe mobile d'accrochage 23 s'est accrochée avec un des crans 25. La tige de traction 40, en position non-tractée, est alors couplée avec le bouton poussoir et est solidaire en translation avec le bouton poussoir. Cette tige de traction est alors complétement engagée dans le logement 201 de la partie basse du bouton poussoir. Cette situation correspond à la figure 2 dans laquelle les moyens d'obturation sont en position d'obturation (l'eau contenue dans le réservoir n'est toujours pas libérée).According to figure 5c , the push button is depressed and reaches a predetermined transient coupling depressed position. Indeed, it is observed that the attachment portion 230 of the movable fastening member 23 is hooked with one of the notches 25. The pull rod 40, in the non-towed position, is then coupled with the push button and is integral in translation with the push button. This pull rod is then fully engaged in the housing 201 of the lower part of the push button. This situation corresponds to the figure 2 in which the closure means are in the closed position (the water contained in the reservoir is still not released).

Suivant la figure 5d, le ressort de compression 50 entraîne la remontée du bouton poussoir jusqu'à sa position de repos, et la tige de traction (couplée avec le bouton poussoir par l'intermédiaire du cran 25 et de la partie d'accrochage 230 de l'organe mobile d'accrochage 23, et donc solidaire en translation du bouton poussoir) est entraînée de sa position non-tractée à une position tractée. Dans cette situation, les moyens d'obturations sont entraînés par le mécanisme de transmission et sont en passage entre la position d'obturation et une position de libération (l'eau s'écoule alors du réservoir).Following the figure 5d , the compression spring 50 causes the push button to rise to its rest position, and the pull rod (coupled with the push button via the notch 25 and the attachment portion 230 of the body mobile hooking 23, and thus integral in translation of the push button) is driven from its non-towed position to a trailed position. In this situation, the sealing means are driven by the transmission mechanism and are in passage between the closed position and a release position (the water then flows from the reservoir).

Selon la figure 5e, le bouton poussoir est sur le point d'atteindre sa position de repos. On observe que la partie de découplage 231 de l'organe mobile d'accrochage 23 commence à coopérer avec la butée de découplage 221 pour découpler la tige de traction du bouton poussoir. Cette situation correspond à la figure 3 dans laquelle les moyens d'obturation sont en position de libération.According to figure 5e , the push button is about to reach its rest position. It is observed that the decoupling portion 231 of the mobile attachment member 23 begins to cooperate with the decoupling stop 221 to decouple the pull rod of the push button. This situation corresponds to the figure 3 in which the closure means are in the release position.

Selon la figure 5f, le bouton poussoir a atteint sa position de repos, et la tige de traction a atteint une position tractée. A cet instant, la tige de traction n'est plus couplée avec le bouton poussoir et est susceptible de retomber sous l'action de son poids ou des moyens d'obturation (la tige de traction étant libérée en translation du bouton poussoir).According to figure 5f , the push button has reached its rest position, and the pull rod has reached a pulled position. At this time, the pull rod is no longer coupled with the push button and is likely to fall under the action of its weight or closure means (the pull rod being released in translation of the push button).

Enfin, selon la figure 5g, on observe la retombée de la tige de traction, qui n'est pas empêchée par l'organe mobile d'accrochage 23. En effet, le bouton poussoir étant dans sa position de repos, la partie de découplage 231 de l'organe mobile d'accrochage 23 coopère avec la butée de découplage 221 et l'organe mobile d'accrochage est retenu éloigné de la tige de traction. Le mécanisme de chasse d'eau revient alors à sa condition initiale illustrée par la figure 5a.Finally, according to the figure 5g the fall of the pulling rod, which is not prevented by the mobile hooking member 23, is observed. In fact, since the push button is in its rest position, the decoupling portion 231 of the movable member hooking 23 cooperates with the decoupling stop 221 and the movable attachment member is held away from the pull rod. The flushing mechanism then returns to its initial condition illustrated by the figure 5a .

Selon le présent mode de réalisation illustré par la figure 4, on observe que le bouton poussoir 2 comporte un bouton principal 20 et un bouton secondaire 21. Le bouton principal correspond à une grande chasse et le bouton secondaire correspond à une petite chasse.According to the present embodiment illustrated by the figure 4 it is observed that the push button 2 comprises a main button 20 and a secondary button 21. The main button corresponds to a large flush and the secondary button corresponds to a small flush.

La cinématique illustrée par les figures 5a à 5g correspond à une grande chasse. On observe dans ce cas, que le bouton poussoir atteint une position enfoncée prédéterminée de couplage transitoire importante, correspondant au cran 25 le plus bas sur la tige de traction 40. En conséquence, la tige de traction sera tractée par le bouton poussoir à une hauteur plus importante de manière à entraîner une libération d'une importante quantité d'eau.The kinematics illustrated by Figures 5a to 5g corresponds to a big hunt. It is observed in this case, that the push button reaches a predetermined deep transient coupling position, corresponding to the lowest notch 25 on the pull rod 40. As a result, the pull rod will be pulled by the push button at a height more important in order to release a large quantity of water.

Dans le cas où le bouton secondaire 21 est actionné, ce dernier limite l'enfoncement du bouton poussoir jusqu'à une position enfoncée prédéterminée de couplage transitoire moins haute (sur la figure 5c, on remarque que le bouton secondaire fait saillie lors de l'enfoncement maximal du bouton poussoir). En conséquence, quand le bouton secondaire est actionné directement, seul le cran 25 le plus haut est accroché par l'organe mobile d'accrochage 23, et la tige de traction ne peut être tractée qu'à une hauteur moins importante que celle correspondant à la grande chasse, entraînant de facto une remontée limitée en haut des moyens d'obturation de leur position d'obturation à l'une des positions de libération. Ainsi, une quantité d'eau plus limitée (par rapport à une grande chasse) est libérée du réservoir.In the case where the secondary button 21 is actuated, the latter limits the depression of the push button to a predetermined depressed position of less high transient coupling (on the figure 5c , we notice that the secondary button protrudes during the maximum depression of the push button). Consequently, when the secondary button is actuated directly, only the highest notch 25 is hooked by the mobile hooking member 23, and the pull rod can be towed only at a height less than that corresponding to the large flush, causing de facto a limited rise at the top of the closure means of their closed position at one of the release positions. Thus, a more limited amount of water (compared to a large flush) is released from the tank.

Les figures 6, 7 et 8 illustrent des moyens de verrouillage 6 de la tige de traction dans une position non-tractée verrouillée. Selon le présent mode de réalisation, ces moyens de verrouillage entraînent également le verrouillage du bouton poussoir dans sa position de repos.The Figures 6, 7 and 8 illustrate locking means 6 of the pull rod in a locked non-towed position. According to the present embodiment, these locking means also cause the locking of the push button in its rest position.

En effet, tel qu'illustré par la figure 6, on observe que le bouton poussoir 2 présente une butée de verrouillage 61 complémentaire d'une lumière 60 présentée par le corps récepteur 22. Dans ce cas, le bouton poussoir est monté également mobile en rotation autour de son axe d'enfoncement dans le corps récepteur. Ainsi, une rotation dans un sens horaire du bouton poussoir alors qu'il est en position de repos permet d'engager la butée de verrouillage dans une partie de verrouillage 600 empêchant le bouton poussoir 2 d'être enfoncé à l'intérieur du corps récepteur.Indeed, as illustrated by the figure 6 , it is observed that the push button 2 has a locking stop 61 complementary to a light 60 presented by the receiving body 22. In this case, the push button is mounted also movable in rotation about its axis of insertion into the body receiver. Thus, a clockwise rotation of the pushbutton while it is in the rest position makes it possible to engage the locking stop in a locking portion 600 preventing the pushbutton 2 from being pressed into the receiving body. .

Selon les figures 7 et 8, on observe que les moyens de verrouillage 6 comprennent :

  • une première partie de verrouillage 203 présentée par le bouton poussoir 2 ;
  • une deuxième partie de verrouillage 400, complémentaire de la première partie de verrouillage, présentée par la tige de traction 40.
According to Figures 7 and 8 it is observed that the locking means 6 comprise:
  • a first locking portion 203 presented by the push button 2;
  • a second locking portion 400, complementary to the first locking portion, presented by the pull rod 40.

Dans la figure 7 (correspondant à la situation illustrée par la figure 6), la première partie de verrouillage 203 n'est pas positionnée en face de la deuxième partie de verrouillage 400 et la tige de traction n'est pas verrouillée dans une position non-tractée verrouillée. Aussi, le bouton poussoir peut alors être enfoncé lui-aussi.In the figure 7 (corresponding to the situation illustrated by the figure 6 ), the first locking portion 203 is not positioned opposite the second locking portion 400 and the pulling rod is not locked in a locked non-towed position. Also, the push button can then be depressed itself too.

Selon la figure 8, au contraire, la première partie de verrouillage 203 est positionnée en face de la deuxième partie de verrouillage 400 et la tige de traction est verrouillée dans une position non-tractée verrouillée. En effet, dans cette situation, la tige de traction ne peut remonter dans le logement 201 présenté par la partie basse du bouton poussoir.According to figure 8 , on the contrary, the first locking portion 203 is positioned opposite the second locking portion 400 and the rod traction is locked in a non-towed locked position. Indeed, in this situation, the pull rod can not go up in the housing 201 presented by the lower part of the push button.

Ces moyens de verrouillage permettent d'empêcher l'utilisation du bouton poussoir mais également de simplifier l'installation du mécanisme de chasse d'eau selon l'invention.These locking means make it possible to prevent the use of the push button but also to simplify the installation of the flushing mechanism according to the invention.

En effet, tel qu'illustré par la figure 10a, le mécanisme comprend deux ensembles destinés à être montés séparément respectivement sur un couvercle 10 du réservoir 1 et sur le réservoir 1.Indeed, as illustrated by the figure 10a , the mechanism comprises two sets intended to be mounted separately respectively on a lid 10 of the tank 1 and on the tank 1.

Plus précisément, le mécanisme de chasse d'eau comprend :

  • un premier ensemble destiné à être monté sur le couvercle 10, ce premier ensemble comprenant le bouton poussoir 2 et une première partie du mécanisme de transmission comprenant la tige de traction 40 ;
  • un deuxième ensemble destiné à être monté dans le réservoir, ce deuxième ensemble comprenant le bâti 3 et une deuxième partie du mécanisme de transmission complémentaire de la première partie du mécanisme de transmission, couplée aux moyens d'obturation 30.
More specifically, the flush mechanism comprises:
  • a first assembly intended to be mounted on the cover 10, this first set comprising the push button 2 and a first part of the transmission mechanism comprising the pull rod 40;
  • a second assembly intended to be mounted in the tank, this second assembly comprising the frame 3 and a second part of the complementary transmission mechanism of the first part of the transmission mechanism, coupled to the closure means 30.

Tel qu'illustré par la figure 9, le mécanisme de transmission comporte des moyens d'accouplement 7 de la première partie du mécanisme de transmission à la deuxième partie du mécanisme de transmission lors d'un positionnement du couvercle sur le réservoir. Ces moyens d'accouplement se décomposent en :

  • des moyens de clipsage mâle 70 présentés par la partie inférieure de la tige de traction 40 ;
  • des moyens de clipsage femelle 71 présentés la deuxième partie du mécanisme de transmission 4 (cette deuxième partie étant constamment couplée aux moyens d'obturation).
As illustrated by figure 9 , the transmission mechanism comprises coupling means 7 of the first part of the transmission mechanism to the second part of the transmission mechanism during a positioning of the lid on the tank. These coupling means are broken down into:
  • male clipping means 70 presented by the lower part of the pull rod 40;
  • female clipping means 71 presented the second part of the transmission mechanism 4 (this second part being constantly coupled to the closing means).

Selon une première variante de réalisation, le premier ensemble comprend les moyens de verrouillage 6 de la tige de traction 40 dans une position non-tractée verrouillée, tels qu'illustrés par les figures 6 à 8. L'accouplement de la première partie du mécanisme de transmission à la deuxième partie du mécanisme de transmission est réalisé lors d'un positionnement du couvercle sur le réservoir, alors que la tige de traction est dans la position non-tractée verrouillée et que les moyens d'obturation sont en position d'obturation.According to a first variant embodiment, the first assembly comprises the locking means 6 of the traction rod 40 in a locked non-towed position, as illustrated by the Figures 6 to 8 . The coupling of the first part of the transmission mechanism to the second part of the transmission mechanism is performed during a positioning of the lid on the tank, while the pulling rod is in the locked non-towed position and the means shutter are in the closed position.

Ainsi, selon les figures 10a et 10b, lors d'une installation du mécanisme de chasse d'eau selon l'invention, les moyens de verrouillage sont actionnés de manière à positionner la tige de traction 40 dans sa position non-tractée verrouillée. Le couvercle du réservoir peut alors être positionné au-dessus du réservoir, puis abaissé de manière à engager les moyens de clipsage mâle 70 dans les moyens de clipsage femelle 71 pour réaliser l'accouplement.Thus, according to the Figures 10a and 10b during an installation of the flushing mechanism according to the invention, the locking means are actuated so as to position the pull rod 40 in its locked non-towed position. The lid of the tank can then be positioned above the tank, and then lowered so as to engage the male clipping means 70 in the female clipping means 71 to perform the coupling.

Une fois le couvercle 10 mis en place sur le réservoir 1, les moyens d'accouplement ont alors couplés le premier ensemble et le deuxième ensemble du mécanisme de chasse d'eau tout en ayant synchronisé les différentes positions des éléments mobiles entre eux.Once the lid 10 has been put in place on the tank 1, the coupling means have then coupled the first set and the second set of the flushing mechanism while having synchronized the different positions of the movable elements with each other.

En effet, grâce à cette conception, les moyens de clipsage mâle 70 s'engagent dans les moyens de clipsage femelle 71 à une « hauteur de réglage » qui dépend de la forme du réservoir. Lors de cette opération d'installation la tige de traction étant dans une position non-tractée verrouillée et les moyens d'obturation étant en position d'obturation, alors la « hauteur de réglage » se règle automatiquement sans intervention supplémentaire de la personne qui réalise l'installation.Indeed, thanks to this design, the male clipping means 70 engage in the female clipping means 71 at a "height adjustment" which depends on the shape of the reservoir. During this installation operation the traction rod being in a non-towed locked position and the shutter means being in the closed position, then the "adjustment height" is automatically adjusted without additional intervention of the person who realizes installation.

Selon une autre variante de réalisation illustrée par les figures 11a à 11d, la cinématique de réglage du mécanisme de transmission se décompose en deux temps, et se réalise lors de la mise en place du couvercle 10 du réservoir 1, puis pendant la première utilisation du bouton poussoir.According to another variant embodiment illustrated by the Figures 11a to 11d , the kinematic adjustment of the transmission mechanism is decomposed in two stages, and is performed during the introduction of the lid 10 of the tank 1, and during the first use of the push button.

En référence à la figure 11a, le couvercle 10 est abaissé sur le réservoir sans intervention préalable sur le bouton poussoir 2. Seule le positionnement en vis-à-vis des moyens de clipsage mâle 70 avec les moyens de clipsage femelle 71 doit être assurée lors de la descente du couvercle sur le réservoir.With reference to the figure 11a , the lid 10 is lowered on the tank without prior intervention on the push button 2. Only the positioning vis-à-vis the male clipping means 70 with the female clipping means 71 must be provided during the lowering of the lid on the tank.

Tel que cela apparaît sur les figures 11b et 11c, les moyens d'accouplement coopèrent progressivement, et la tige de traction 40 est entraînée dans sa position tractée, haute, sous l'effet de l'engagement des moyens de clipsage mâle 70 dans les moyens de clipsage femelle 71.As it appears on the Figures 11b and 11c , the coupling means progressively cooperate, and the pull rod 40 is driven into its towed position, high, under the effect of the engagement of the male clipping means 70 in the female clipping means 71.

Une fois le couvercle 10 en place, la tige de traction 40 est dans une position intermédiaire : elle n'est pas tractée mais reste dans une position haute.Once the cover 10 in place, the pull rod 40 is in an intermediate position: it is not towed but remains in a high position.

La figure 11d illustre une première utilisation du bouton poussoir 2. Cette première utilisation du bouton poussoir permet d'enfoncer la tige de traction 40 pour engager complètement les moyens de clipsage mâle 70 dans les moyens de clipsage femelle 71. De cette manière, l'utilisateur réalise de manière transparente un ajustement de la « hauteur de réglage » pour synchroniser les différentes positions des éléments mobiles entre eux.The figure 11d illustrates a first use of the push button 2. This first use of the push button allows to push the pull rod 40 to fully engage the male clipping means 70 in the female clipping means 71. In this way, the user realizes transparent way adjustment of the "adjustment height" to synchronize the different positions of the moving elements between them.

En d'autres termes, lors du premier passage du bouton poussoir de sa position de repos à sa position enfoncée, il force le passage de la tige de traction de sa position tractée à sa position non-tractée et ainsi l'engagement des moyens de clipsage mâle 70 à l'intérieur des moyens de couplage femelle 71.In other words, during the first passage of the push button from its rest position to its depressed position, it forces the passage of the pulling rod from its towed position to its non-towed position and thus the commitment of the means of male clipping 70 inside the female coupling means 71.

Ainsi, lors de la première utilisation du bouton poussoir, la chasse d'eau n'est pas déclenchée du fait que la tige de traction, en position haute dite position tractée, n'est pas encore synchronisée avec le reste du mécanisme de transmission et avec les moyens d'obturation. Ce n'est qu'après la première utilisation du bouton poussoir, dans cette variante de réalisation, que le mécanisme de chasse d'eau peut être utilisé normalement.Thus, during the first use of the push button, the flush is not triggered by the fact that the pull rod, in the high position called the towed position, is not yet synchronized with the rest of the transmission mechanism and with the sealing means. Only after the first use of the push button, in this embodiment, the flush mechanism can be used normally.
