Description

L'invention se rapporte à un mécanisme de commande placé à l'intérieur d'un réservoir de chasse d'eau de W.C, selon le préambule de la revendication 1.The invention relates to a control mechanism placed inside a toilet flush tank, according to the preamble of claim 1.

Jusqu'à une époque récente, les mécanismes du genre précité comportaient une timonerie traversant le couvercle du réservoir et commandant l'ouverture par tirage de la soupape de l'évacuation de l'eau de rinçage comprenant un joint venant obturer le trou de vidange du réservoir (trou de forte section pour permettre l'évacuation de 8 à 10 litres d'eau en quelques secondes).Until recent times, the mechanisms of the aforementioned kind included a wheelhouse passing through the cover of the tank and controlling the opening by pulling of the valve for the discharge of the rinsing water comprising a seal closing the drain hole of the tank (large section hole to allow the evacuation of 8 to 10 liters of water in a few seconds).

Pour éviter d'avoir à maintenir le tirage sur la timonerie durant l'opération d'évacuation, la soupape est pourvue généralement d'un flotteur situé à proximité dudit joint et dont le volume est calculé pour compenser le poids de l'équipage mobile du mécanisme. L'effort de traction correspond au poids de la colonne d'eau sur le joint, diminué éventuellement de la force verticale ascentionnelle générée par le flotteur (de l'ordre de 500g. quand il en existe un comme par exemple dans l'U.S. - A 4.486.906).To avoid having to maintain the draft on the wheelhouse during the evacuation operation, the valve is generally provided with a float located near the said joint and the volume of which is calculated to compensate for the weight of the moving equipment of the mechanism. The tensile force corresponds to the weight of the water column on the joint, possibly reduced by the vertical ascentional force generated by the float (of the order of 500g. When there is one such as for example in the US - A 4.486.906).

Dans certains appareils, cet effort est très important (U.S. - A - 4.527.296) sans pour autant, constituer une difficulté réelle même pour un enfant, puisque les moyens de préhension du bouton extérieur de manoeuvre de la timonerie sont prévus en conséquence (voir aussi U.S. - A 4.149.283 utilisant de l'air sous pression).In some aircraft, this effort is very significant (US - A - 4,527,296) without however constituting a real difficulty even for a child, since the means for gripping the external button for maneuvering the wheelhouse are provided accordingly (see also US - A 4,149,283 using pressurized air).

Deux innovations sont apparues récemment :

  • la première, est purement d'ordre esthétique et réside à remplacer la manoeuvre par tirage d'actionnement de la soupape, par une manoeuvre inverse réalisée à partir d'une touche-poussoir, comme le veut la mode actuelle des commandes des appareils électro-ménagers,
  • la seconde vise à réaliser des économies d'eau, dans certains cas en intervenant à nouveau sur la timonerie commandant la soupape pour interrompre le rinçage.
Two innovations have appeared recently:
  • the first, is purely aesthetic and resides in replacing the maneuver by actuation of the valve, by a reverse maneuver carried out using a push button, as is the current mode of control of electro- household,
  • the second aims to save water, in some cases by intervening again on the wheelhouse controlling the valve to interrupt rinsing.

La première de ces modifications pose aux constructeurs un certain nombre de problèmes souvent contradictoires. Il faut citer par exemple la différence de grandeurs de forces produites par traction (préhension par deux doigts) ou par poussée (effleurement d'un seul doigt) et aussi la nécessité d'intercaler entre le poussoir et la soupape dont l'ouverture reste soumise à un mouvement ascentionnel, un dispositif inverseur de sens opératoire assurant, en outre, la démultiplication du mouvement (un centimètre d'enfoncement de la touche-poussoir assurant une levée de trois centimètres de la soupape.The first of these modifications poses manufacturers a number of often contradictory problems. Mention should be made, for example, of the difference in magnitudes of forces produced by traction (gripping by two fingers) or by pushing (touching with one finger) and also the need to interpose between the pusher and the valve, the opening of which remains subject to an upward movement, an operating direction reversing device ensuring, moreover, the reduction of the movement (one centimeter of depressing the push button ensuring a lifting of three centimeters of the valve.

En ce qui concerne les moyens visant l'économie d'eau, leur adjonction était facile avec les appareils à tirage (voir par exemple BE - A647 270) mais devient un casse-tête avec les dispositifs à touche poussoir.With regard to the means of saving water, their addition was easy with the drawing devices (see for example BE - A647 270) but becomes a headache with the push button devices.

En effet, ou ce poussoir est solidaire de la soupape et alors celui-ci reste enfoncé durant l'entière vidange, ou il n'en est pas solidaire alors le poussoir remonte mais la timoneire reste enfoncéeIndeed, either this pusher is integral with the valve and then the latter remains depressed during the complete emptying, or it is not integral with it then the pusher goes up but the wheelhouse remains pressed

Par ailleurs, les fabricants de mécanismes de chasse d'eau se sont rendu compte que les flotteurs destinés à maintenir la soupape en position haute pendant la vidange du réservoir finissaient par retomber lorsque le niveau d'eau ayant baissé, leur volume efficace ne compensait plus le poids de l'équipage mobile du mécanisme.On the other hand, the manufacturers of flushing mechanisms realized that the floats intended to keep the valve in the high position during the emptying of the tank ended up falling back when the water level having dropped, their effective volume no longer compensated the weight of the moving part of the mechanism.

Divers perfectionnements ont été réalisés pour retarder la descente de celui-ci, par exemple :

  • En verrouillant ce flotteur en position haute et en l'associant à des moyens de désarmement lorsque l'eau atteint son point bas (FR -A LEBOUCHARD no 1.506.551).
  • En enfermant la soupape dans une enceinte dont la vidange est différée de celle du réservoir, cette enceinte pouvant être constituée par une cloche totalement ou suffisamment étanche à l'air pour que le niveau de l'eau y emmagasiné soit maintenu haut par dépression (CH - A HUBER no 302. 469 ou FR - A - SPHINX no 1.318.833).
Various improvements have been made to delay the descent of it, for example:
  • By locking this float in the high position and associating it with disarming means when the water reaches its lowest point (FR -A LEBOUCHARD n o 1.506.551).
  • By enclosing the valve in an enclosure whose emptying is differed from that of the tank, this enclosure can be constituted by a bell totally or sufficiently airtight so that the level of the water stored therein is kept high by vacuum (CH - A HUBER No. 302 469 or FR - A - SPHINX No. 1,318,833).

Une telle enceinte peut également être constituée par un simple réservoir enfermant un flotteur et pourvu d'une "fuite" à sa partie inférieure et dont le débit conditionne l'écoulement de l'eau et, par conséquent, la descente du flotteur solidaire de la soupape.Such an enclosure can also be constituted by a simple reservoir enclosing a float and provided with a "leak" at its lower part and the flow of which conditions the flow of water and, consequently, the descent of the float secured to the valve.

Cette fuite étant matérialisée par un trou présente l'inconvénient de pouvoir s'obturer si des impuretés sont présentes dans l'eau.This leak being materialized by a hole has the drawback of being able to close off if impurities are present in the water.

La présente invention se rapporte à une structure nouvelle fonctionnant par pression sur un bouton et qui comporte un flotteur mobile selon le niveau de l'eau dans une enceinte, ce flotteur étant tel que sa force ascentionnelle soulage le poids de l'équipage mobile au point de rendre acceptable l'importance de la pression à exercer sur le bouton poussoir, ledit flotteur servant également à retarder la descente de la soupape dont la commande comprend aussi des moyens permettant d'interrompre la vidange par une simple nouvelle pression sur le poussoir.The present invention relates to a new structure operating at the press of a button and which comprises a movable float depending on the water level in an enclosure, this float being such that its upward force relieves the weight of the movable crew at the point to make acceptable the importance of the pressure to be exerted on the push button, said float also serving to delay the descent of the valve, the control of which also includes means making it possible to interrupt the emptying by a simple new pressure on the push button.

Le mécanisme objet de l'invention comprend un bouton poussoir 1, un dispositif inverseur 2, un flotteur creux 3, un boîtier tubulaire 4, une soupape portée par le flotteur et fermant la vidange pour la position basse de celui-ci.The object of the invention mechanism comprises a push button 1, a reversing device 2, a hollow float 3, a tubular housing 4, a valve carried by the float and closing the drain for the low position thereof.

Le flotteur 3 est constitué par un tube cylindrique dans une partie supérieure 3a et par un bulbe 3b à sa partie inférieure.The float 3 is constituted by a cylindrical tube in an upper part 3a and by a bulb 3b in its lower part.

Le flotteur 3 est enfermé dans le boîtier tubulaire 4, qui, au niveau supérieur des ouïes 4a est limité par une cloison transversale 4e laissant passer la partie rétrécie 3c du flotteur 3 portant le bulbe 3b.The float 3 is enclosed in the tubular housing 4, which, at the upper level of the openings 4a is limited by a transverse partition 4e allowing the narrowed part 3c of the float 3 carrying the bulb 3b to pass.

La particularité de cet ensemble est que, d'une part, la partie supérieure 3a du flotteur est cylindrique de diamètre constant pour sa portion pouvant être d'un niveau inférieur au niveau normal de l'eau dans le réservoir et que, d'autre part, le boîtier 4 est aussi tubulaire et d'un diamètre intérieur à peine supérieur au diamètre extérieur dudit flotteur.The particularity of this assembly is that, on the one hand, the upper part 3a of the float is cylindrical with a constant diameter for its portion which can be of a level below the normal level of the water in the tank and that, on the other apart, the housing 4 is also tubular and of an internal diameter barely greater than the external diameter of said float.

Dans une rainure, entre la partie rétrécie 3c et le bulbe 3b, le flotteur 3 porte le joint 6 (éventuellement rigidifié par une rondelle métallique 6a). Le boîtier 4 est fixé sur la paroi inférieure Ra du réservoir R, par un culot 4c percé de l'orifice d'évacuation, ladite paroi étant bloquée contre la platine 4b de ce culot qui limite les ouïes 4a vers le bas par un écrou 5, lequel comporte un bourrelet 4d qui sert de siège au clapet formé par le joint 6.In a groove, between the narrowed part 3c and the bulb 3b, the float 3 carries the seal 6 (possibly stiffened by a metal washer 6a). The housing 4 is fixed to the lower wall Ra of the reservoir R, by a base 4c pierced with the discharge orifice, said wall being blocked against the plate 4b of this base which limits the openings 4a downwards by a nut 5 , which comprises a bead 4d which serves as a seat for the valve formed by the seal 6.

Dans sa position basse (figure 1), le flotteur 3 ferme donc la soupape d'évacuation par son propre poids si le réservoir R est vide.In its low position (Figure 1), the float 3 therefore closes the discharge valve by its own weight if the tank R is empty.

Le remplissage du réservoir R se fait traditionnellement par une vanne à bascule assujettie à un second flotteur (dispositif non représenté).The filling of the tank R is traditionally done by a rocker valve subject to a second float (device not shown).

Par le passage entre 3c et 4g, les niveaux dans le réservoir R et le canal annulaire B s'équilibrent.By the passage between 3c and 4g, the levels in the reservoir R and the annular channel B are balanced.

Si le réservoir est plein, la force agissant sur le joint 6 comprend en sus du poids du flotteur et de sa commande, celui de la colonne d'eau enfermée dans les canaux annulaires A et B.If the tank is full, the force acting on the seal 6 includes, in addition to the weight of the float and its control, that of the water column enclosed in the annular channels A and B.

S'il y a surverse dans R celle-ci s'élimine en passant par le corps creux du flotteur.If there is an overflow in R, it is eliminated through the hollow body of the float.

Celui-ci porte un chapeau 7 duquel s'élèvent deux oreilles 7a (figure 3a) se faisant vis-à-vis et pourvues chacune, d'une fente verticale 7b.The latter carries a cap 7 from which rise two ears 7a (FIG. 3a) facing each other and each provided with a vertical slot 7b.

Le dispositif inverseur (figures 1,6 et 7) comprend une pièce 8 sur laquelle s'articulent deux leviers symétriques 9 et 10 se terminant par un crochet 9a (et 10a) destinés à collaborer avec les fentes 7b des oreilles 7a.The reversing device (Figures 1.6 and 7) comprises a part 8 on which two symmetrical levers 9 and 10 are articulated ending in a hook 9a (and 10a) intended to collaborate with the slots 7b of the ears 7a.

Les leviers 9 et 10 tourillonnent dans les flans parallèles du capot 11 du boîtier 4, les tourillons 12 étant situés entre leur liaison avec le corps 8 et les crochets 9a (ou 10a). De cette manière, le mouvement descendant de ce corps 8 se traduit par une montée des crochets et, par conséquent, par une traction sur les oreilles 7a provoquant le soulèvement du flotteur 3.The levers 9 and 10 revolve in the parallel blanks of the cover 11 of the housing 4, the pins 12 being located between their connection with the body 8 and the hooks 9a (or 10a). In this way, the downward movement of this body 8 results in an increase in the hooks and, consequently, in a traction on the ears 7a causing the lifting of the float 3.

Le corps 8 est relié au poussoir 1 au moyen d'une timonerie 13 dont la partie filetée 13a visse dans un écrou de réglage 14 coulissant dans l'alésage du corps 8 (sans pouvoir tourner) et dont la partie supérieure 13b de section cruciforme peut. Se déplacer dans un logement de section complémentaire creusée dans le poussoir 1.The body 8 is connected to the pusher 1 by means of a linkage 13, the threaded part 13a of which screws into an adjusting nut 14 sliding in the bore of the body 8 (without being able to rotate) and whose upper part 13b of cruciform section can. Move into a housing of additional section dug in the pusher 1.

Le boîtier 4 par son capot 11 est fixé au couvercle R2 du réservoir par une entretoise tubulaire filetée de réglage 15 autorisant des variations de hauteur du réservoir. Le réglage de hauteur, par vissage ou dévissage de l'entretoise 15 entraîne celui de la timonerie 13 qui se visse ou se dévisse simultanément dans l'écrou de réglage 14.The housing 4 by its cover 11 is fixed to the cover R2 of the tank by a threaded tubular adjustment spacer 15 allowing variations in height of the tank. The height adjustment, by screwing or unscrewing the spacer 15 causes that of the wheelhouse 13 which is screwed or unscrewed simultaneously in the adjustment nut 14.

Le poussoir 1 peut coulisser dans cette entretoise, étant rappelé en position haute par un ressort 16.The pusher 1 can slide in this spacer, being returned to the high position by a spring 16.

Avantageusement, le poussoir est logé dans une embase 17.Advantageously, the pusher is housed in a base 17.

Il est facile de comprendre que si l'on appuie sur le poussoir 1, celui-ci, par la tige 13 va repousser l'écrou 14 qui entraîne alors dans sa descente le corps 8 faisant pivoter les leviers 9 et 10 de la position visible sur la figure 1 à celle de la figure 2. Par leur élévation, ces leviers soulèvent les oreilles 7 et, partant, le flotteur 3 dont le joint quitte le siège 4d et ouvre le passage entre le culot 4c et le réservoir R par les ouïes 4a.It is easy to understand that if the pusher 1 is pressed, the latter, by the rod 13 will push back the nut 14 which then drives the body 8 in its descent making the levers 9 and 10 pivot from the visible position in FIG. 1 to that of FIG. 2. By their elevation, these levers raise the ears 7 and, consequently, the float 3, the seal of which leaves the seat 4d and opens the passage between the base 4c and the tank R by the gills 4a.

En raison de la démultiplication, au faible enfoncement du poussoir, correspond une ouverture importante de la soupape et cela sans effort, en raison du peu de poids de la colonne d'eau agissant sur le joint.Due to the reduction, the low depression of the plunger, corresponds to a large opening of the valve and this effortlessly, due to the low weight of the water column acting on the seal.

Par contre, l'effet de flottaison produit par le flotteur 3 dans l'espace annulaire B dont le niveau ne descend que très lentement, non seulement, maintient la soupape ouverte, mais encore fait remonter le flotteur jusqu'à ce que la face supérieure du joint 6 vienne appliquer contre le bourrelet 4g de la cloison 4e. Théoriquement, ce contact s'opposerait au vidage du canal annulaire B, si le bourrelet 4g ne comportait une encoche (figure 5) 4h autorisant une fuite. Contrairement aux fuites produites par des perçages utilisés dans des dispositifs connus, l'encoche 4h n'a que peu de risque d'être obturée par une impureté de l'eau, parce qu'elle forme un passage horizontal et que si même elle se bouchait, la manoeuvre du flotteur et donc du joint 6 serait suffisante pour la libérer.On the other hand, the buoyancy effect produced by the float 3 in the annular space B, the level of which drops only very slowly, not only keeps the valve open, but also causes the float to rise until the upper face of the joint 6 comes to apply against the bead 4g of the partition 4e. Theoretically, this contact would oppose the emptying of the annular channel B, if the bead 4g did not have a notch (Figure 5) 4h authorizing a leak. Unlike the leaks produced by holes used in known devices, the 4h notch has little risk of being blocked by an impurity of the water, because it forms a horizontal passage and that if it even clogged, the operation of the float and therefore of the seal 6 would be sufficient to release it.

Dans la remontée du flotteur 3, son chapeau, partiellement ouvert, rencontre l'écrou 14 de la tige 13 qui, à son tour, remonte le poussoir 1 (figure 3).In the ascent of the float 3, its cap, partially open, meets the nut 14 of the rod 13 which, in turn, rises the pusher 1 (Figure 3).

Si à ce moment on réappuie sur ce poussoir 1, on fait descendre le flotteur puisqu'il est en appui contre la tige 13, sa descente ouvre la communication entre B et A, l'espace B se vide, la flottaison cessant, le flotteur retombe et la soupape se ferme, interrompant la vidange qui permet une économie d'eau.If at this moment we press again on this pusher 1, the float is lowered since it is in abutment against the rod 13, its descent opens the communication between B and A, the space B empties, the floating ceases, the float falls back down and the valve closes, interrupting the drain which saves water.

Comme on le voit selon l'invention, le flotteur joue différents rôles parfois contraires.As can be seen according to the invention, the float plays different roles which are sometimes contrary.

L'inverseur 2 peut avantageusement être moulé en une seule pièce (polypropylène) (figures 6 et 7), les leviers 9 et 10 étant articulés sur les ailes 18 du corps 8 par deux séries de gorges 19-20, 19a-20a. permettant des pliures dans les deux sens.The inverter 2 can advantageously be molded in one piece (polypropylene) (Figures 6 and 7), the levers 9 and 10 being articulated on the wings 18 of the body 8 by two series of grooves 19-20, 19a-20a. allowing folds in both directions.

Claims (11)

  1. Flushing mechanism, placed inside a W.C. cistern (R) comprising:
    - a tubular housing (4), with a lower base (4c) through which the drainage opening runs and communicating with the said cistern (R) via broad inlets (4a) and which is fixed to the bottom (Ra).
    - a hollow cylindrical float (3) sliding inside the said housing (4), which float comprising an upper part (3a) with a broad diameter and a lower part or tail piece (3b-3c) with a smaller diameter.
    - a seal valve, closing the drain, the flap of which is constituted by a seal (6) carried by the lower part of the said float, the seat of which is formed by a flange (4d) running around the periphery of the drainage opening located on the lower base (4c) of the tubular housing.
    - a gear (13) enabling the float (3) to be lifted between its lower position and its upper position and therefore enabling the said valve to be opened by means of a manoeuvring button (1), the lower internal part of the housing (4) bearing an internal annular projection (4e) at a level which is only just above that of the upper part of the inlets (4a), the said projection allowing the tail piece (3c) to pass with slight friction and secondly [sic], the seal (6) which closes the valve when the float is in its lover position, thus creating watertightness by pressing on a flange (4g) provided on the lower face of the said annular projection when the said float is in its upper position.
  2. Mechanism according to claim 1 characterised in that the annular space (B) recessed between the external wall of the float (3) and the internal wall of the housing (4) is as small as possible.
  3. Mechanism according to one of the previous claims characterised in that the cistern (R) communicates with the said housing (4) via holes located at a level below that of the open upper part of the float when it is in its lowest position.
  4. Mechanism according to claim 2 characterised in that the flange (4g) of this annular projection (4e) exhibits a notch (4h) of calibrated dimensions allowing the timed drainage of the annular space (B), when the float is in its highest position.
  5. Mechanism according to any one of the previous claims, in which the control button (1) of the gear is a push button, the said gear comprising an inverter device (2) transforming the descending movement of the said push button into an ascending movement of the float characterised in that this inverter (2) includes a body (8) which can move up and down, within which slides a bush (14) fitted with a stop actuating the body, the said bush being screwed into the threaded end of the rod (13), the second end of which, being cruciform or equivalent in section, is engaged in the push button (1) controlling its descent in opposition to a spring (16).
  6. Mechanism according to claim 5, characterised in that levers (9-10) are hinged on the sides of the body (8) and pivot within a fixed part, for example a cap (11) of the housing (4) by means of journals (12) located between their ends.
  7. Mechanism according to one of the previous claims characterised in that the float (3) is fitted with a perforated top (7) bearing two vertical brackets (7a) which face one another and are each pierced by a vertical slot (7b).
  8. Mechanism according to claims 6 and 7, characterised in that the free ends of the levers (9-10) which are hook-shaped (9a-10a) are engaged in the slots (7b).
  9. Mechanism according to one of the previous claims, characterised in that the mobile body (8) and the levers (9-10) are made from a single piece of moulded plastic, and the levers can be stiffened by means of a reinforcement placed as an insert, the folding being obtained by reducing the thickness of the material.
  10. Mechanism according to one of the previous claims, characterised in that when the flotation within the space (B) causes the float (3) to rise, an element of the upper end of the latter meets the control rod (13) or a part which is integral to it, in such a way that the rise of the float is accompanied by that of the push button (1).
  11. Mechanism according to one of the previous claims characterised in that the cap (11) of the housing (4) is secured to the lid (Rc) of the cistern (R), by means of a threaded height-adjustment spacer (15) resulting in adjustment of the gear (13) by screwing it or unscrewing it within the nut (14).
