Abstract

The emptying and over flow system has a disc (35) placed in front of the overflow opening (12). The rotary motion of the disc is converted into linear motion by a mechanical system e.g. a pinion (33) cooperating with a rack (32). The linear motion is applied to a tube (31) having a double function of being a water collector and a movement transmission element. Its lower part extends into a rigid assembly bent at an angle, so that end is horizontal and is situated under the stem (7) of the discharge valve (8). It may alternately raise or lower the stem and the assembly of the mechanism is in the plane between the axes (5,11) of the emptying and overflow holes (2,12) respectively. USE - Esp. for bath(tub)s.

Description

Le système de vidage et trop plein des baignoires modernes est, en règle quasi générale, constitué par une bonde dont le clapet est soulevé avec la manoeuvre en rotation d'un disque placé devant le trou du trop plein lequel est raccordée avec la bonde, le mouvement étant transmis par un câble Bowden. The system for emptying and overflowing modern baths is, as a general rule, constituted by a plug whose valve is raised with the rotary operation of a disc placed in front of the overflow hole which is connected with the plug, the movement being transmitted by a Bowden cable.

Un tel système, s'il donne généralement satisfaction au plan fonctionnel, présente l'inconvénient d'être compliqué et, de ce fait, très onéreux. Such a system, while generally satisfactory on the functional level, has the drawback of being complicated and, therefore, very expensive.

La présente invention se rapporte à up système d'un coût beaucoup moindre du fait de son extrême simplicité qui assure en même temps sa parfaite fiabilité. I1 s'adapte facilement et rapidement sur n'importe quelle baignoire de type courant. The present invention relates to an up system of a much lower cost due to its extreme simplicity which at the same time ensures its perfect reliability. It fits easily and quickly on any common type bathtub.

Le dispositif selon l'invention se présente exactement comme ceux de type actuel puisqu'il comporte également un disque pivotant placé devant le trou du trop plein et un clapet de bonde placé dans le fond de la baignoire, la différence portant sur le mode de transmission du mouvement linéaire qui s'applique non plus à un câble Bowden mais à- un tube qui collecte les eaux de surverse et, à sa partie inférieure, se prolonge par un élément coudé dont l'extrémité se trouve en position de soulever le clapet ou le laisser retomber selon la rotation du disque. The device according to the invention is exactly like those of the current type since it also includes a pivoting disc placed in front of the overflow hole and a drain valve placed in the bottom of the bath, the difference relating to the mode of transmission. linear movement which no longer applies to a Bowden cable but to a tube which collects overflow water and, at its lower part, is extended by a bent element the end of which is in position to raise the valve or let it fall back as the disc rotates.

Pour bien comprendre l'invention, on pourra utilement se référer à la figure 1 qui est une coupe longitudinale de la partie de baignoire où est installé le mécanisme et qui fait apparaître également les dispositifs particuliers de montage et d'adaptation. To fully understand the invention, reference may usefully be made to FIG. 1 which is a longitudinal section of the part of the bath where the mechanism is installed and which also shows the particular mounting and adaptation devices.

La bonde (1) est fixée sur le dessous de la baignoire par un moyen quelconque comme une rondelle (3) qui comporte une partie inférieure cylindrique filetée (4) qui s'introduit dans le trou (2) et, sur son axe (5), un tube (6) pour le guidage de la queue (7) du clapet (8). The drain (1) is fixed to the underside of the bathtub by any means such as a washer (3) which has a threaded cylindrical lower part (4) which is introduced into the hole (2) and, on its axis (5 ), a tube (6) for guiding the tail (7) of the valve (8).

La bonde (1) comporte une gaine horizontale de dérivation (9) dont l'axe (10) est placé, comme l'ensemble des pièces constituant le mécanisme, dans le plan vertical que forment ensemble l'axe (5) et l'axe (11) du trou de trop plein (12). La gaine (9), dirigée vers l'extérieur de la paroi (13) ou se trouve (12), est ouverte à son extrémité où en Drolonaement elle se raccorde de manière étanch avec une avine (14) de même section au moyen d'un manchon élastique (15). The drain (1) comprises a horizontal sheath shunt (9) whose axis (10) is placed, like all the parts constituting the mechanism, in the vertical plane that together form the axis (5) and the axis (11) of the overflow hole (12). The sheath (9), directed towards the outside of the wall (13) or is located (12), is open at its end where in Drolonaement it is connected in a sealed manner with an oat (14) of the same section by means of 'an elastic sleeve (15).

La gaine (14) se prolonge par un coude (16) qui débouche vers le haut dans un compartiment (17) qui longe la face externe de la paroi (13) et dont la partie supérieure (18) se raccorde avec un tube de guidage (19) muni d'un joint torique logé (20a). The sheath (14) is extended by a bend (16) which opens upwards into a compartment (17) which runs along the external face of the wall (13) and the upper part (18) of which is connected with a guide tube (19) provided with a housed O-ring (20a).

Disposé sur le même axe (21), de même diamètre que (19) et muni d'un joint torique (20 b), un autre tube de guidage (22) se trouve placé dans le fond (23) d'une gaine parallélépipédique (24), ouverte à sa partie supérieur-e, et dont la face avant (25) qui comporte un orifice circulaire (26) s'applique contre la face externe de la paroi (13) dans une Position où l'orifice (26) se place en correspondance avec le trou (12) de trop plein. Arranged on the same axis (21), of the same diameter as (19) and provided with an O-ring (20 b), another guide tube (22) is placed in the bottom (23) of a parallelepiped sheath (24), open at its upper part, and the front face (25) of which has a circular orifice (26) bears against the external face of the wall (13) in a Position where the orifice (26 ) is placed in correspondence with the overflow hole (12).

Un moyen de fixation quelconque comme, par exemple, un élément cylindrique fileté (27) dont l'axe (28) qui coinci(le avec l'axe (11) est perpendiculaire au plan de (25) coopère avec un écrou (29) pour solidariser la gaine (24) avec la paroi (13). Any fixing means such as, for example, a threaded cylindrical element (27) whose axis (28) which coincides (the with the axis (11) is perpendicular to the plane of (25) cooperates with a nut (29) to secure the sheath (24) with the wall (13).

Les tubes (19) et (22) sont filetés l'un selon un pas à droite et l'autre selon un pas à gauche de sorte qu'un tube (30) taraudé respectivement droite et gauche à chacune de sn extrémités les solidarise en se vissant simultanément sur l'uii et l'autre. The tubes (19) and (22) are threaded one according to a step to the right and the other according to a step to the left so that a tube (30) tapped respectively right and left at each of its ends secures them in screwing simultaneously on the iui and the other.

On pourrait, naturelAclllellt, saisis sortir du cadre de l'invention, réaliser cette fixation par d'autres moyens comme, par exemple, des tiges filetées coopérant avec des pattes percées disposées latéralement et en correspondance, respectivement sur (19) et (22). We could, naturalAclllellt, entering outside the scope of the invention, achieve this fixing by other means such as, for example, threaded rods cooperating with pierced tabs arranged laterally and in correspondence, respectively on (19) and (22) .

Guidé dans son coulissement par les tubes (19) et (22), un tube (31) porte, à sa partie supérieure et dans son prolongement un dispositif de commande comme, figuré à titre d'exemple non limitatif, une crémaillère (32) qui coopère avec un pignon (33) fixé sur l'axe (34) du disque de manoeuvre (35), axe (34) qui coincide égalemcllt avec (11) . L'ensemble est améliagé et dimensiotiné de maiiières à ce qu'en toutes circonstances les extrémités du tube (31) débouchent à l'intérieur, respectivement, du compartiment (17) et la gaîlle (24). Guided in its sliding by the tubes (19) and (22), a tube (31) carries, at its upper part and in its extension a control device like, illustrated by way of nonlimiting example, a rack (32) which cooperates with a pinion (33) fixed on the axis (34) of the operating disc (35), axis (34) which also coincides with (11). The assembly is improved and dimensioned so that in all circumstances the ends of the tube (31) open into the interior, respectively, of the compartment (17) and the sheath (24).

Sur la partie inférieure du tube (31) et dans son prolongement, est fixé une barre (36) coudée selon le même angle que celui que forment ensemble la gamine (14) et le compartiment (17) de telle sorte que sa partie terminale (37) se trouve à l'intérieur de (14) en position sensiblement hc.zontale et dans le plan médian général de l'ensemble lorsque le pignon (33) est en prise avec la crémaillère (32). On the lower part of the tube (31) and in its extension, is fixed a bar (36) bent at the same angle as that formed together by the kid (14) and the compartment (17) so that its end part ( 37) is inside (14) in a substantially horizontal position and in the general median plane of the assembly when the pinion (33) is engaged with the rack (32).

Sur l'extrémité (38) de la partie (37) se fixe une barre (39) dont l'arète supérieure (40), à sa partie terminale, se place en dessous de (7). On the end (38) of the part (37) is fixed a bar (39) whose upper edge (40), at its terminal part, is placed below (7).

Le fonctionnement du mécanisme se comprend aisément
Lorsqu'on fait pivoter le dique (35) autour de son axe (34), on imprime à l'ensemble constitué par la crémaillère (32), le tube (31) les barres (36) et (39) un mouvement linéaire de bas en haut qui, par l'intermédiaire de larAete supérieure (40) de (39),soulève le clapet (8) et le laisse retomber sur son siège lorsqu'on tourne le disque (35) en sens contraire, la course étant déterminée et limitée par l'espace dont disposent les barres (37) et (39) à l'intérieur des gaines (14) et (9).The operation of the mechanism is easily understood
When the pivot (35) is pivoted about its axis (34), the assembly constituted by the rack (32), the tube (31), the bars (36) and (39) is printed with a linear movement of bottom up which, by means of the upper head (40) of (39), lifts the valve (8) and lets it fall back on its seat when the disc (35) is turned in the opposite direction, the stroke being determined and limited by the space available to the bars (37) and (39) inside the sheaths (14) and (9).

Le trop plein se déverse, tout naturellement par l'orifice 26, la gaine (24), le tube 31, le compartiment (17) et la gaine (14) jusqu'à la bonde (1). The overflow overflows, quite naturally through the orifice 26, the sheath (24), the tube 31, the compartment (17) and the sheath (14) up to the drain (1).

Afin d'éviter que de l'eau de surverse ne stagne dans le fond de la gaine (24), un tube souple (41) de faible section relie le fond (23) au compartiment (17). Enfin la bonde se maintient en position d'ouverture par la friction des joints toriques (20 a) et {20 b) contre l'extérieur du tube (31). In order to prevent overflow water from stagnating in the bottom of the sheath (24), a flexible tube (41) of small section connects the bottom (23) to the compartment (17). Finally, the plug is kept in the open position by the friction of the O-rings (20a) and {20b) against the outside of the tube (31).

L'exposé qui précède, se référant à la figure I, se rapporte au mécanisme en situation opérationnelle ; monté sur la baignoire. The foregoing description, referring to FIG. I, relates to the mechanism in operational situation; mounted on the bathtub.

L'exposé qui va suivre se rapporte à la fabrication des différents éléments constitutifs, de leur assemblage et de l'adaptation de l'ensemble sur la baignoire, compte-tenu des différences qui peuvent exister d'un modèle à l'autre. The following discussion relates to the manufacture of the various constituent elements, their assembly and the adaptation of the assembly on the bath, taking into account the differences which may exist from one model to another.

Du fait que, à lrexception de la crémaillère (32) toutes les pièces du mécanisme ont un plan de symétrie, il est possible pour celles qui sont de forme creuse comme (1), et (24) de les mouler par injection en deux demi-coquilles qui sont ensuite collées ou soudées selon ce plan de symétrie. Because, with the exception of the rack (32) all the parts of the mechanism have a plane of symmetry, it is possible for those which are of hollow form like (1), and (24) to mold them by injection in two half -shells which are then glued or welded according to this plane of symmetry.

Ce mode de fabrication s'applique également à la pièce formée par (14) (16) et (17) mais après qu'on y ait placé l'ensemble formé par le tube (31) et la barre (36, ensemble dont la forme générale coudée empêche qu'on puisse l'introduire après coup. This manufacturing method also applies to the part formed by (14) (16) and (17) but after having placed there the assembly formed by the tube (31) and the bar (36, assembly whose generally angled shape prevents it from being introduced afterwards.

Le montage s'effectue de la manière suivante :
La crémaillère (32) ayant été fixée sur le tube (31), on visse un des bouts du tube (30) sur (19) puis l'autre bout sur (22). Ces vissages effectués sur une très faible profondeur, correspondent à la plus grande profondeur possible de baignoire.The assembly is carried out as follows:
The rack (32) having been fixed on the tube (31), one end of the tube (30) is screwed on (19) then the other end on (22). These screw connections performed on a very shallow depth, correspond to the greatest possible depth of the bathtub.

Après qu'on ait fixé (24) sur (13) avec l'écrou (29), on fait pivoter le tube (30) dans le sens du vissage en maintenant la gaine (14) en position axiale, ce qui la fait monter jusqu'à ce qu'un tèton (42) placé sur sa partie supérieure se mette en butée contre le fond de la baignoire ce qui correspond à la position où les extrémités de (14) et de (8) sont appelées à se trouver au regard l'unede l'autre. After having fixed (24) on (13) with the nut (29), the tube (30) is pivoted in the direction of screwing while keeping the sheath (14) in an axial position, which makes it rise until a pin (42) placed on its upper part abuts against the bottom of the bath which corresponds to the position where the ends of (14) and (8) are called to be at the look at each other.

Du fait que l'extrémité (38) de (37) se trouve à l'extérieur de (14) on peut sans difficulté y adapter la barre horizontale (39) qui, pour fonctionner rationnellement devra être parfaitement horizontale.Because the end (38) of (37) is outside of (14) it is without difficulty to adapt the horizontal bar (39) which, in order to function rationally, must be perfectly horizontal.

L'angle que forment entre eux le tube (30) et la partie (37) est une donnée de construction du mécanisme qui correspond à l'inclinaison normale de la paroi (13) qui, elle, est une donnée de construction de la baignoire, légèrement variable d'un modèle à l'autre. The angle that the tube (30) and the part (37) form between them is a construction datum of the mechanism which corresponds to the normal inclination of the wall (13) which is a construction datum of the bathtub. , slightly variable from one model to another.

I1 en résulte que, à l'issue du montage, la partie rectiligne (37) peut ne pas se trouver en position parfaitement horizontale. Pour rattraper la différence et placer (39) en position horizontale, l'accouplement rigide de (38) avec (39) se réalise au moyen d'un système règlable comme, par exemple, la mise en correspondance, pour l'une et l'autre pièce, de trous circulaires canelés traversés par un tourillon également cane lé. I1 follows that, at the end of the assembly, the straight part (37) may not be in a perfectly horizontal position. To make up the difference and place (39) in a horizontal position, the rigid coupling of (38) with (39) is achieved by means of an adjustable system such as, for example, the matching, for one and the other. 'other piece, fluted circular holes crossed by a pin also cane lé.

On =ixe ensuite la bonde (1) après avoir coupé les longueurs excédentaires de la gaine (8) et de la barre (39) puis on rabat sur l'extrémité de (8) le manchon élastique (15) qui se trouvait en attente sur l'extrémité de (14) et on fixe le tuyau souple (41). We then fix the plug (1) after cutting the excess lengths of the sheath (8) and the bar (39) and then fold over the end of (8) the elastic sleeve (15) which was waiting on the end of (14) and the flexible pipe (41) is fixed.

I1 ne reste plus alors qu'à mettre en place le dispositif de commande dans lequel la crémaillère dispose d'une plage de fonctionnement suffisamment étendue pour couvrir toutes les profondeurs possibles de baignoires. I1 then only remains to set up the control device in which the rack has an operating range sufficiently wide to cover all the possible depths of baths.
