Abstract

The closer is designed for use with a double valve mixer tap in which a central component (15) is raised for closure and lowered for opening and has a vertical rod (16) attached to its underside which interacts with a float (19) in a cavity (9). It also has a housing (5) fixed behind a vertical wall (3) of the bath in line with its overflow hole (4), an overflow pipe (6) with an upper extension (7) having a horizontal top edge (8). The float cavity (9) is connected to the housing (5) and via a branch pipe (13) to the overflow pipe.

Description

La présente invention se rapporte à différents aménagements etThe present invention relates to various arrangements and

perfectionnements aux brevets français 97 09901 et PCT /FR 98 01728 pour la improvements to French patents 97,09901 and PCT / FR 98 01728 for the

partie de ces brevets qui concerne les mitigeurs pour baignoire. part of these patents which relates to bathtub mixers.

Ces mitigeurs sont du type dont l'ouverture s'effectue par enfoncement manuel de la pièce centrale laquelle, pour la fermeture, coopère avec un flotteur dont le soulèvement est directement lié à la montée du niveau These mixers are of the type whose opening is effected by manual insertion of the central part which, for closing, cooperates with a float whose lifting is directly linked to the rise in level

dans la baignoire.in the bathtub.

Cette disposition présente un double inconvénient à savoir: 1 - Elle nécessite un trou supplémentaire dans la paroi de la baignoire o se This arrangement has a double disadvantage, namely: 1 - It requires an additional hole in the wall of the bath where

trouve le trou de trop plein.finds the overflow hole.

2 - La fermeture est extrêmement lente. 2 - Closing is extremely slow.

La présente invention remédie à ces inconvénients. Elle se rapporte à un dispositif qui n'utilise que le trou de trop plein et provoque une fermeture quasi instantanée du mitigeur dès que le niveau atteint le point le plus bas dudit The present invention overcomes these drawbacks. It relates to a device which uses only the overflow hole and causes an almost instantaneous closing of the mixer as soon as the level reaches the lowest point of said

trou de trop plein.overflow hole.

L'invention se rapporte également aux moyens par lesquels la manoeuvre de l'inverseur bain/douche neutralise le dispositif de fermeture automatique du mitigeur ceci afin de permettre à l'usager d'utiliser la douche The invention also relates to the means by which the operation of the bath / shower diverter neutralizes the automatic closing device of the mixer in order to allow the user to use the shower.

sans provoquer l'arrêt intempestif de l'écoulement. without causing the flow to stop unexpectedly.

Pour bien comprendre l'invention, on pourra utilement se référer aux trois figures ci-annexées données à titre d'exemple non limitatif et qui sont des vues en plan de l'ensemble en position respectivement de fermeture, To fully understand the invention, reference may usefully be made to the three attached figures given by way of non-limiting example and which are plan views of the assembly in the respectively closed position,

Le corps (1) du mitigeur est fixé sur le rebord horizontal (2) de la baignoire adjacent avec la paroi verticale (3) dans laquelle est logé le trou (4) de The body (1) of the mixer tap is fixed to the horizontal rim (2) of the adjacent bathtub with the vertical wall (3) in which the hole (4) is housed.

Sur la paroi (3) et en correspondance avec le trou (4) se fixe un boîtier (5) dans lequel débouche, dirigé vers le bas, le tube vertical (6) qui est On the wall (3) and in correspondence with the hole (4) is fixed a housing (5) into which opens, directed downwards, the vertical tube (6) which is

relié à l'écoulement de vidange de la baignoire, ici non figuré. connected to the drain drain of the bathtub, not shown here.

Ce tube (6) se prolonge à l'intérieur du boîtier (5) par un élément de This tube (6) is extended inside the housing (5) by an element of

tube vertical (7) dont l'extrémité supérieure s'inscrit dans le plan horizontal (8). vertical tube (7) whose upper end is in the horizontal plane (8).

Par un conduit horizontal (25), le boîtier (5) communique avec une cavité (9) placée en contrebas par rapport au plan (10) dans lequel s'inscrit le By a horizontal conduit (25), the housing (5) communicates with a cavity (9) placed below relative to the plane (10) in which the

point le plus bas (11) du trou (4).lowest point (11) of the hole (4).

Sur le fond (12) de la cavité (9) est branché un tuyau (13) qui est dirigé vers le bas et se raccorde avec le tube (6) en un confluent (14) se situant On the bottom (12) of the cavity (9) is connected a pipe (13) which is directed downwards and is connected with the tube (6) at a confluence (14) lying

en dessous du plan de (12).below the plane of (12).

Sur le dessous de la pièce centrale (15) de commande est fixée une tige verticale (16) qui, lorsque ladite pièce (15) est enfoncée, se place, par son extrémité (17) au contact de la face supérieure (18) d'un flotteur (19) placé dans On the underside of the central control part (15) is fixed a vertical rod (16) which, when said part (15) is pressed, is placed, by its end (17) in contact with the upper face (18) d '' a float (19) placed in

le fond de la cavité (9).the bottom of the cavity (9).

A partir de cette situation d'enfoncement de la pièce (15) le fonctionnement du dispositif est le suivant: Lorsque le niveau de remplissage atteint le plan (10) I'eau passe directement du boîtier (5) à la cavité (9) qui se remplit. Le flotteur (19) est alors soulevé et, en repoussant la tige (16) vers le haut, provoque la fermeture du mitigeur. La cavité (9) se vidange ensuite dans le tube (6) par l'intermédiaire du tuyau (13) qui est calibré de manière à ce que le débit de vidange de la dite From this situation of insertion of the part (15) the operation of the device is as follows: When the filling level reaches the plane (10) the water passes directly from the housing (5) to the cavity (9) which is filling up. The float (19) is then raised and, by pushing the rod (16) upwards, causes the mixing valve to close. The cavity (9) then empties into the tube (6) via the hose (13) which is calibrated so that the emptying rate of the said

cavité (9) soit très inférieur à celui du remplissage de la baignoire. cavity (9) is much lower than that of the filling of the bathtub.

La hauteur comprise entre les plans (10) et (8) est établie de manière à correspondre au volume d'eau déplacé par une personne de The height between the planes (10) and (8) is established so as to correspond to the volume of water displaced by a person of

corpulence normale entrant dans la baignoire lorsque celle-ci est pleine. normal build entering the tub when it is full.

Sur la partie horizontale du verseur (20) se place l'inverseur (21) dont le piston (22) est disposé verticalement. Cet inverseur est du type dans lequel la On the horizontal part of the pourer (20) is placed the reverser (21) whose piston (22) is arranged vertically. This inverter is of the type in which the

position relevée correspond à la douche et la position abaissée au bain. raised position corresponds to the shower and the lowered position to the bath.

Sur le piston (22) est fixés, dirigée vers le bas, une tige verticale (23) dont l'extrémité inférieure porte un clapet (24) qui se loge à l'intérieur du conduit On the piston (22) is fixed, directed downwards, a vertical rod (23) whose lower end carries a valve (24) which is housed inside the duct

horizontal (25).horizontal (25).

Le clapet (24) est constitué par une plaque (26) qui comporte un trou (27) calibré de manière à ce que, en position abaissée de l'inverseur, ledit trou (27) se place en correspondance avec la section intérieure du conduit (25). A l'inverse, dans la position relevée de l'inverseur, la plaque 26 obture le conduit The valve (24) consists of a plate (26) which has a hole (27) calibrated so that, in the lowered position of the reverser, said hole (27) is placed in correspondence with the internal section of the duct. (25). Conversely, in the raised position of the reverser, the plate 26 closes the conduit

(25) de manière à empêcher tout écoulement vers la cavité (9). (25) so as to prevent any flow towards the cavity (9).
