Abstract

The device prevents the jamming of a valve which closes automatically after a definite time interval, the valve incorporating a push-button (15) which is depressed to lift an obturator off the valve seat (12). The obturator is rigidly connected to a casing (17) housing a displaceable piston (16). The piston communicates with the water feed through a calibrated hole (20). The piston is rigidly connected to the push button which transmits movement to the casing through the combined effects of friction and suction. The piston may be recoil sprung and may be connected to the button by a rod (14) which passes slidably through the obturator. If the button is held in the depressed position the chamber gradually fills with water, thus moving the obturator back onto the seat regardless.

Description

La présente invention est relative à un dispositif de sécurité empêchant le blocage du mécanisme de commande des robinets à fermeture temporisée. The present invention relates to a safety device preventing the blocking of the control mechanism of time-closing taps.

De tels robinets comportent une chambre de temporisation dans laquelle peut se déplacer un piston lié en translation au clapet du robinet et dont le déplacement axial est commandé par un bouton poussoir. Such taps include a delay chamber in which a piston linked in translation with the valve flap can move and whose axial movement is controlled by a push button.

En enfonçant le bouton poussoir, on détermine le soulèvement du clapet et le déplacement du piston dans son cylindre ou chambre de temporisation qui communique avec l'arrivée d'eau par ltentremise d'un orifice calibré. Progressivement liteau pénètre dans la chambre précitée et repousse le piston ce qui a pour effet d'appliquer le clapet contre son siège. By depressing the push button, the valve is lifted and the piston moved in its cylinder or time chamber which communicates with the water supply through a calibrated orifice. Gradually batten enters the aforementioned chamber and pushes back the piston which has the effect of applying the valve against its seat.

Naturellement, ce déplacement dans le sens de la fermeture n1 est possible qu'à la condition que l'utilisateur ne maintienne pas son action sur le bouton poussoir car,dans ce cas, le piston est bloqué puisque la force manuelle est bien supérieure à celle de la pression qui tend à le repousser. Naturally, this movement in the closing direction n1 is possible only on condition that the user does not maintain his action on the push button because, in this case, the piston is blocked since the manual force is much greater than that pressure that tends to push it away.

Dans ces conditions, on comprend qutil est très facile de bloquer un tel robinet pour s'opposer à sa fermeture temporisée. Under these conditions, it is understood that it is very easy to block such a tap to oppose its timed closure.

La présente invention, qui remédie à ces inconvénients, est relative à un robinet à fermeture temporisée dans lequel le temps de maintien de l'enfoncement du bouton poussoir est sans action sur la temporisation. The present invention, which overcomes these drawbacks, relates to a time-closed tap in which the time for which the push button is depressed has no action on the time delay.

Selon l'invention,ce résultat est obtenu en rendant le clapet solidaire d'un boîtier dans lequel peut se déplacer le piston usuel pourvu de son orifice calibré, le soulèvement du clapet, lors de l'enfonce- ment du bouton poussoir, étant déterminé par le déplacement du piston qui entraîne ledit boîtier. According to the invention, this result is obtained by making the valve integral with a housing in which the usual piston provided with its calibrated orifice can move, the lifting of the valve, when the push button is pressed, being determined by the displacement of the piston which drives said housing.

lie robinet de l'invention peut être utilisé notamment,pour commander un robinet de douche à fermeture teEptisée.  The valve of the invention can be used in particular to control a shower valve with teEptized closure.

En effet, actuellement, les installations de douche comportent un robinet à fermeture temporisée dont l'ouverture est commandée en faisant communiquer la chambre de temporisation avec l'air libre. A cet effet, ladite chambre de temporisation est reliée par l'entremise d'une canalisation à un second robinet, dTune structure très simple comportant un clapet commandé par un poussoir.Tant que le poussoir est enfoncé l'eau, pénétrant dans la chambre de temporisation par l'orifice calibré, est évacuée par la canalisation précitée et la temporisation ne se produit pas.Il ressort donc des explications ci-dessus que le robinet de l'invention est particulièrement apte à être utilisé pour commander une installation de douche en remplacement du second robinet précité. Indeed, currently, the shower installations include a time-closing tap whose opening is controlled by communicating the time chamber with the open air. To this end, said delay chamber is connected by means of a pipe to a second tap, dTune very simple structure comprising a valve controlled by a pusher. As long as the pusher is pushed in water, entering the chamber time delay through the calibrated orifice, is evacuated by the aforementioned pipe and the time delay does not occur. It therefore follows from the above explanations that the valve of the invention is particularly suitable for being used to control a shower installation as a replacement of the aforementioned second tap.

L'invention sera mieux comprise nar la description qui va suivre faite en se référant aux dessins annexés sur lesquels
La figure 1 est une vue schématique montrant la commande d'une installation usuelle de douche;
La figure 2 est une vue en coupe du robinet de l'invention, tous les organes mobiles étant représentés en position normale de fermeture;
La figure 3 est une vue analogue à la figure 2 montrant la position des organes mobiles à l'instant où l'utilisateur enfonce le bouton poussoir,
La figure 4 est une vue analogue à la figure 2 montrant la position respective du clapet et du piston lorsque l'utilisateur maintient intempestivement son action sur le bouton poussoir.The invention will be better understood nar the description which follows made with reference to the accompanying drawings in which
Figure 1 is a schematic view showing the control of a conventional shower installation;
Figure 2 is a sectional view of the valve of the invention, all the movable members being shown in the normal closed position;
FIG. 3 is a view similar to FIG. 2 showing the position of the movable members at the moment when the user presses the push button,
Figure 4 is a view similar to Figure 2 showing the respective position of the valve and the piston when the user inadvertently maintains his action on the push button.

En se reportant à la figure 1 on voit qu'une installation de douche usuelle se compose d'une canalisation 1 d'arrivée d'eau,normalement obturée par le clapet d'un robinet 2 à fermeture temporisée comportant donc une chambre de temporisation 3 dans laquelle peut se déplacer un piston 4 comportant un orifice calibré (non représenté) faisant communiquer ladite chambre 3 et l'arrivée d'eau. Referring to FIG. 1, it can be seen that a usual shower installation consists of a water inlet pipe 1, normally closed by the valve of a time-closed tap 2 therefore comprising a time chamber 3 in which can move a piston 4 having a calibrated orifice (not shown) communicating said chamber 3 and the water inlet.

Lorsque la chambre de temporisation 3 est pleine d'eau le robinet est fermé et pour l'ouvrir il faut permettre l'eau contenue dans ladite chambre de s'écouler à l'extérieur. When the delay chamber 3 is full of water, the tap is closed and to open it, the water contained in said chamber must be allowed to flow outside.

De la façon connue, ce résultat est obtenu en prévoyant dans la chambre 3 un orifice 5 relié par une canalisation 6 à un dispositif de commande constitué, de façon simple, par un bouton poussoir 7 d'actionnement d'un clapet obturateur 8. En enfonçant le bouton poussoir on écarte le lapet E de son siège et l'eau contenue dans la chambre 3 s'écoule par l'orifice de décharge dudit dispositif de com- manse. In the known manner, this result is obtained by providing in the chamber 3 an orifice 5 connected by a pipe 6 to a control device constituted, in a simple manner, by a push button 7 for actuating a shutter valve 8. In pressing the push button, the lapper E is moved away from its seat and the water contained in the chamber 3 flows through the discharge orifice of said control device.

L'inconvénient d'une telle installation réside dans le fait que si l'utilisateur maintient son action sur le bouton poussoir 7, le dispositif de temporisation du robinet 2 ne fonctionne pas. The drawback of such an installation lies in the fact that if the user maintains his action on the push button 7, the device for delaying the tap 2 does not work.

L'invention qui remédie à cet inconvénient est relative à un robinet a fermeture temporisée pouvant être utilisé pour constituer,notamment, l'organe de commande d'un robinet usuel à fermeture temporisée d'une installation de douche. The invention which overcomes this drawback relates to a time-closed tap which can be used to constitute, in particular, the control member of a conventional tap with time-delayed closing of a shower installation.

Un tel robinet va être décrit en regard des figures 2 à 4. Such a tap will be described with reference to FIGS. 2 to 4.

Selon un mode de réalisation, le corps 9 présente deux orifices 10 et Il respectivement d'entrée et de sortie de l'eau entre lesquels est interposé un obturateur constitué par un siège 12, prévu dans le corps 9 et par un clapet 13 mobile. According to one embodiment, the body 9 has two orifices 10 and II respectively for entering and leaving the water, between which there is interposed a shutter constituted by a seat 12, provided in the body 9 and by a movable valve 13.

lie clapet 13 est guidé sur une tige 14 compor -ant, à une extrémité un bouton poussoir 15 et, à l'autre extrémité, un piston 18 engagé dans un boitier 17 avec interposition d'un joint 18 à lèvres ledit boîtier portant le clapet 13. the valve 13 is guided on a rod 14 comprising, at one end a push button 15 and, at the other end, a piston 18 engaged in a housing 17 with interposition of a seal 18 with lips said housing carrying the valve 13.

La face interne du piston 1.6 forme en combinai- son avec le boitier 17 une chambre 19 à voluae va
iable.The internal face of the piston 1.6 forms, in combination with the housing 17, a chamber 19 with a volua
heck.

L'arrivée d'eau communique avec la chambre 19 par l'entremise d'un trou calibré 20 prévu dans le piston 16. The water inlet communicates with the chamber 19 through a calibrated hole 20 provided in the piston 16.

En l'absence d'action sur le bouton poussoir 15, le clapet 13 est appliqué contre son siège par l'entremise d'un ressort 21 interposé entre le corps 9 et ledit bouton poussoir 15. In the absence of action on the push button 15, the valve 13 is applied against its seat by means of a spring 21 interposed between the body 9 and said push button 15.

Lorsqu'on enfonce le bouton poussoir @5, le piston 16 se déplace selon la flèche F1 ( figurs 3) en entraînant le boitier 17 et, par suite, le clapet @3. L'eau s'écoule par l'orifice 11. When the push button @ 5 is pressed, the piston 16 moves along the arrow F1 (FIGS. 3), driving the housing 17 and, consequently, the valve @ 3. Water flows through port 11.

Deux causes contribuent à l'entraîrement du boitier 17 : la friction du joint 18 et un phénomène d'aspiration. En effet, lorsqu'à partir de la position représentés sur la figure 2 on enfonce le bouton poussoir, on constate que le volume de la chambre 19 est minimal et comme le déplacement du piston est rapide l'eau contenue dans le corps 9 n'a pas le temps, durant cette action,de traverser l'orifice 20. Two causes contribute to the entrainment of the housing 17: the friction of the seal 18 and a phenomenon of aspiration. Indeed, when from the position shown in Figure 2 we push the push button, we see that the volume of the chamber 19 is minimal and as the displacement of the piston is rapid the water contained in the body 9 n ' has no time, during this action, to cross hole 20.

Dès que le clapet 13 est soulevé la chambre 3 est en décharge et le clapet du robinet 2 s'ouvre de la façon usuelle, l'eau traversant l'orifice 10, le siège 12 et étant évacuée par l'orifice de sortie 11. As soon as the valve 13 is raised, the chamber 3 is discharged and the valve valve 2 opens in the usual manner, the water passing through the orifice 10, the seat 12 and being discharged through the outlet orifice 11.

Si à partir de la position représentée sur la figure 3 l'utilisateur relâche le bouton poussoir 15, le ressort 21 rappelle l'ensemble mobile en sens inverse à la flèche F1, le clapet 13 s'applique contre son siège, la chambre 3 du robinet principal est obturée et la temporisation commence. If from the position shown in Figure 3 the user releases the push button 15, the spring 21 recalls the movable assembly in the opposite direction to the arrow F1, the valve 13 is applied against its seat, the chamber 3 of the main valve is blocked and the timer starts.

Par contre,si par une action de l'utilisatuer le bouton poussoir reste enfoncé par suite d'un blccage soit par une pression prolongée ou réalisé d'une façon quelconque, l'eau qui provient de la canalisation 6, raccordée à l'orifice 10, traverse le trou calibré 20, pénètre dans la chambre 19 et repousse progressivement le clapet 13 contre son siège (figure 4). Lorsque le clapet 13 est en pression contre son siège, la temporisation du robinet 2 commence mais la durée totale de l'ouverture du robinet 2 est au plus égale à la somme des temporisations du robinet 2 et de son dispositif de commande. On the other hand, if by an action of the user the push button remains pressed due to blockage either by a prolonged pressure or carried out in any way, the water which comes from the pipe 6, connected to the orifice 10, crosses the calibrated hole 20, enters the chamber 19 and gradually pushes the valve 13 against its seat (Figure 4). When the valve 13 is under pressure against its seat, the time delay for the valve 2 begins but the total duration of the opening of the valve 2 is at most equal to the sum of the times for the valve 2 and its control device.

Dès lors, on comprend que par une utilisation judicieuse de l'installation on peut obtenir que la pomme de douche délivre de l'eau durant un temps déterminé qui peut varier entre deux limites fixées par le constructeur par un réglage judicieux de la section des trous calibrés. Therefore, it is understood that by judicious use of the installation it is possible to obtain that the shower head delivers water for a determined time which can vary between two limits fixed by the manufacturer by judicious adjustment of the section of the holes. calibrated.

Dans l'exemple représenté un ressort 22 tend à repousser le clapet 13 contre son siège et ce, pour tenir compte que la pression de l'eau qui pénètre par l'orifice 10 est relativement faible. In the example shown a spring 22 tends to push the valve 13 against its seat and this, to take into account that the pressure of the water entering the orifice 10 is relatively low.

Mais, dans le cas d'une utilisation classique du robinet,c'est-à-dire d'une utilisation selon laquelle la pression de l'eau du réseau serait appliquée directement à l'orifice d'entrée du robinet, un tel ressort ne serait pas forcément nécessaire.D'une façon générale, la force du ressort 22 est sensiblement égale aux forces tendant à entraîneur le clapet lors du déplacement du piston tout en restant légèrement inférieure. Par ailleurs, la force du ressort 22 est inférieure à celle du ressort 21.But, in the case of a conventional use of the tap, that is to say of a use according to which the pressure of the mains water is applied directly to the inlet port of the tap, such a spring Generally, the force of the spring 22 is substantially equal to the forces tending to drive the valve during the displacement of the piston while remaining slightly lower. Furthermore, the force of the spring 22 is less than that of the spring 21.

Bien entendu la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à -toutes variantes ayant le même résultat, à savoir :permettre le fonctionnement normal du dispositif de temporisation d'un robinet quelles que soient les manoeuvres effectuées en vue de supprimer la temporisation.  Of course, the present invention is not limited to the embodiment described and shown, but extends, on the contrary, to -any variants having the same result, namely: allowing normal operation of the timing device of a tap whatever either the maneuvers carried out with a view to eliminating the time delay.
