Description

La présente invention se rapporte à une baignoire destinée plus particulièrement à l'usage de personnes agées ou handicapées.The present invention relates to a bathtub intended more particularly for the use of the elderly or disabled.

L'utilisation des baignoires classiques pose des difficultés à des personnes agées ou handicapées en ce sens qu'il est difficile pour de telles personnes de pénétrer dans la baignoire et d'en sortie par leurs propres moyens. En effet, si la baignoire est en saillie au-dessus du sol, il est nécessaire d'enjamber la bord de la baignoire; si la baignoire est encastrée dans le sol, il est nécessaire de se baisser ou de se redresser pour surmonter la différence de niveau entre le sol et la fond de la baignoire.The use of conventional baths poses difficulties for elderly or disabled people in the sense that it is difficult for such people to enter and exit the bath on their own. Indeed, if the bathtub protrudes above the ground, it is necessary to step over the edge of the bathtub; if the bathtub is embedded in the floor, it is necessary to lower or straighten it to overcome the difference in level between the floor and the bottom of the bathtub.

Dans les deux cas, cela implique des mouvements d'amplitude relativement importante que les personnes agées ou handicapées ne sont souvent pas à même d'effectuer, tout au moins sans l'aide d'une autre personne.In both cases, this involves movements of relatively large amplitude that the elderly or disabled are often unable to perform, at least without the help of another person.

On a déjà proposé de munir une baignoire d'une porte pivotant autour d'un axe sensiblement vertical pour faciliter l'accès à l'intérieur de cette baignoire.It has already been proposed to provide a bathtub with a door pivoting about a substantially vertical axis to facilitate access to the interior of this bathtub.

Par ailleurs, il a déjà été proposé (brevet US n° 3 371 354) de munir une telle baignoire ouvrante d'un dispositif de sécurité du type à flotteur, empêchant l'ouverture de la porte tant que la baignoire contient de l'eau.Furthermore, it has already been proposed (US Patent No. 3,371,354) to provide such an opening bathtub with a safety device of the float type, preventing the opening of the door as long as the bathtub contains water. .

Dans la baignoire ouvrante suivant le brevet US 3371 354, une plage collectrice d'eau équipée d'une bonde d'écoulement et entourée d'un rebord est prévue devant la porte d'accès de la baignoire. En effet, il peut arriver sur cette baignoire connue que l'occupant de la baignoire, après avoir fermé la bonde de vidange de la baignoire, laisse couler de l'eau dans cette dernière alors qu'il n'a pas fermé la porte d'accès ou n'a fermé cette porte que de façon incomplète. L'eau s'écoulant ainsi de la baignoire est récupérée par la plage collectrice.In the opening bathtub according to US patent 3371 354, a water collecting area equipped with a drain and surrounded by a rim is provided in front of the access door of the bathtub. Indeed, it can happen on this known bathtub that the occupant of the bathtub, after having closed the drain for draining the bathtub, lets water flow into the latter when he has not closed the door d 'access or closed this door only partially. The water thus flowing from the bathtub is collected by the collecting platform.

Cette plage collectrice double cependant l'encombrement de la baignoire, augmente considérablement le prix de revient de cette dernière et complique également l'installation de la baignoire dans la mesure où les tuyaux d'écoulement des bondes de la baignoire et de la plage collectrice et le syphon de ces tuyaux doivent être encastrés dans le plancher.This collecting range, however, doubles the size of the bathtub, considerably increases the cost price of the latter and also complicates the installation of the bathtub insofar as the pipes for draining the bungs from the bathtub and the collecting range and the siphon of these pipes must be embedded in the floor.

Une autre baignoire connue à porte d'accès (brevet US 2 991 482) comprend une chemise chauffante et un dispositif combiné commandant à la fois la fermeture de la porte, L'écoulement de l'eau contenue dans la chemise chauffante et dans l'espace intérieur de la baignoire et la condamnation de la porte par flotteur tant que la baignoire contient de l'eau. Sur cette baignoire connue, le seuil de porte est surélevé par rapport à la bonde de vidange de la baignoire. Cependant, ce seuil surélevé n'empêche pas avec certitude, dans le cas où l'occupant de la baignoire laisse couler de l'eau dans cette dernière alors que la porte n'est pas fermée ou n'est pas complètement fermée, que cette eau s'échappe de la baignoire par la porte. En effet, l'eau ne peut s'écouler de la baignoire par la bonde que dans une position bien déterminée du dispositif combiné de commande, tandis que dans toutes les autres positions, l'écoulement de l'eau par la bonde est impossible de sorte que l'eau introduite alors dans la baignoire par la robinetterie de remplissage s'accumule au fond de la baignoire et s'écoule par l'ouverture de la baignoire dès que son niveau atteint le bord inférieur de cette ouverture.Another known bathtub with access door (US Pat. 2,991,482) comprises a heating jacket and a combined device controlling both the closing of the door, the flow of water contained in the heating jacket and in the interior space of the bathtub and the door is locked with a float as long as the bathtub contains water. On this known bathtub, the door threshold is raised relative to the drain for the bathtub. However, this raised threshold does not prevent with certainty, in the case where the occupant of the bathtub lets water flow in the latter while the door is not closed or is not completely closed, this water escapes from the bathtub through the door. Indeed, water can only flow from the bathtub through the drain in a well-defined position of the combined control device, while in all other positions, the flow of water through the drain is impossible. so that the water then introduced into the bathtub through the filling fitting accumulates at the bottom of the bathtub and flows through the opening of the bathtub as soon as its level reaches the lower edge of this opening.

La présente invention a pour objet une baignoire ouvrante qui se distingue des baignoires connues de ce type par sa structure simple, son faible encombrement, son prix de revient réduit, son accès aisé et sa sécurité de fonctionnement accrue.The present invention relates to an opening bathtub which differs from known baths of this type by its simple structure, its small size, its reduced cost price, its easy access and its increased operating safety.

L'invention a donc pour objet une baignoire ouvrante, en particulier à usage de personnes agées ou handicapées, formée d'une partie fixe et d'une partie mobile susceptible de pivoter par rapport à la partie fixe autour d'un axe d'articulation sensiblement vertical situé sur un côté longitudinal de la baignoire, ladite baignoire comprenant un dispositif de sécurité de fermeture empêchant l'ouverture de la baignoire tant que cette dernière contient de l'eau. Suivant l'invention, la baignoire est divisée en deux parties dans un plan transversal à la longueur de la baignoire, passant par la partie la plus profonde de la baignoire, les deux parties de la baignoire assurant en position de fermeture, au droit du plan transversal de division, une surface intérieure continue de la baignoire, et cette dernière comprend, en outre, un dispositif de sécurité de remplissage empêchant le remplissage de la baignoire tant que cette dernière n'est pas complètement fermée.The invention therefore relates to an opening bathtub, in particular for the use of the elderly or disabled, formed of a fixed part and a movable part capable of pivoting relative to the fixed part about an axis of articulation. substantially vertical located on a longitudinal side of the bathtub, said bathtub comprising a closing safety device preventing the opening of the bathtub as long as the latter contains water. According to the invention, the bathtub is divided into two parts in a plane transverse to the length of the bathtub, passing through the deepest part of the bathtub, the two parts of the bathtub ensuring in the closed position, in line with the plane transverse dividing, a continuous inner surface of the bath, and the latter further comprises a filling safety device preventing the filling of the bath until the latter is not completely closed.

Suivant un mode de réalisation de l'invention, le dispositif de sécurité de remplissage comprend un palpeur actionné à la fermeture complète de la baignoire pour libérer l'arrivée de l'eau à une robinetterie de remplissage de la baignoire. Ce palpeur empêche donc, tant que la baignoire n'est pas complètement fermée, toute arrivée d'eau à la robinetterie de remplissage.According to one embodiment of the invention, the filling safety device comprises a feeler actuated when the tub is completely closed to release the arrival of water at a tub filling tap. This probe therefore prevents, as long as the bathtub is not completely closed, any arrival of water at the filling valve.

Ledit palpeur est constitué par un poussoir faisant sailie, sous l'action d'un ressort, sur la surface de contact de l'une des deux parties de la baignoire avec l'autre. Ce poussoir agit sur une robinetterie d'arrêt montée en amont de la robinetterie de remplissage de la baignoire et commandant l'arrivée d'eau froide et d'eau chaude à cette robinetterie de remplissage.Said probe is constituted by a pusher making sailie, under the action of a spring, on the contact surface of one of the two parts of the bath with the other. This plunger acts on a shut-off valve mounted upstream of the bath filler fitting and controlling the arrival of cold and hot water to this filling fitting.

De préférence, ledit poussoir est monté au voisinage du côté de la baignoire opposé à l'axe d'articulation.Preferably, said pusher is mounted in the vicinity of the side of the bath opposite the hinge axis.

Le dispositif de sécurité de fermeture de la baignoire comprend des moyens commandés par un flotteur actionné en fonction du niveau de l'eau dans la baignoire, lesdits moyens bloquant le dispositif de fermeture de la baignoire en position fermée tant que la baignoire contient de l'eau. Lesdits moyens comprennent deux pattes horizontales, espacées verticalement, solidaires de l'une des deux parties de la baignoire, avec deux trous alignés, l'un dans chacune desdites pattes. Lesdits moyens comprennent, en outre, une patte horizontale reliée au dispositif de fermeture de la baignoire de manière à être mobile dans un plan horizontal entre lesdites deux pattes solidaires de l'une des parties de la baignoire, ladite patte mobile comportant ègalement un trou. Enfin, lesdits moyens comprennent une tige verticale solidaire d'un flotteur et traversant les trous alignés desdites trois pattes lorsque le dispositif de fermeture de la baignoire est en position fermée et lorsque le flotteur est soulevé par la montée du niveau d'eau dans la baignoire.The safety device for closing the bathtub comprises means controlled by a float actuated as a function of the level of the water in the bathtub, said means locking the tub closing device in the closed position as long as the tub contains water. Said means comprise two horizontal legs, spaced vertically, integral with one of the two parts of the bath, with two aligned holes, one in each of said legs. Said means further comprise a horizontal tab connected to the device for closing the tub so as to be movable in a horizontal plane between said two tabs integral with one of the parts of the tub, said movable tab also comprising a hole. Finally, said means comprise a vertical rod secured to a float and passing through the aligned holes of said three legs when the device for closing the bathtub is in the closed position and when the float is raised by the rise in the water level in the bathtub .

Ledit flotteur se trouve dans une cuve verticale communiquant avec l'intérieur de la baignoire suivant le principe des vases communicant.Said float is located in a vertical tank communicating with the interior of the bathtub according to the principle of communicating vases.

Le dispositif de fermeture de la baignoire comprend avantageusement au moins un loquet de type à genouillère dont la manette de manoeuvre pivote autour d'un axe vertical. Ladite patte mobile est alors solidaire de cette manette de manoeuvre.The device for closing the bath advantageously comprises at least one latch of the toggle type, the operating handle of which pivots about a vertical axis. Said movable tab is then secured to this maneuver.

De préférence, les loquets du type à genouillère sont au moins au nombre de deux et leurs manettes de manoeuvre sont reliées entre elles par une barre verticale. Ladite patte est alors formée avantageusement par l'extrémité supérieure coudée de cette barre et la poignée de manoeuvre est reliée à cette barre.Preferably, the latches of the toggle type are at least two in number and their operating levers are connected together by a vertical bar. Said tab is then advantageously formed by the bent upper end of this bar and the operating handle is connected to this bar.

En se référant au dessin schématique annexé on va décrire ci-après plus en détail un exemple de réalisation illustratif et non limitatif d'une baignoire conforme à l'invention; sur ce dessin:

  • la figure 2 est une vue en plan de la baignoire de la figure 1, à l'état ouvert;
  • la figure 3 est une vue en élévation latérale de la baignoire de la figure 1;
  • la figure 4 est une coupe partielle, à plus grande échelle, suivant IV-IV de la figure 3.
Referring to the appended schematic drawing, an illustrative and nonlimiting exemplary embodiment of a bathtub according to the invention will be described below in more detail; on this drawing:
  • Figure 1 is a plan view of a bathtub according to the invention in the closed state;
  • Figure 2 is a plan view of the bath of Figure 1 in the open state;
  • Figure 3 is a side elevational view of the tub of Figure 1;
  • FIG. 4 is a partial section, on a larger scale, along IV-IV of FIG. 3.

La baignoire ouvrante illustrée par le dessin est une baignoire-siège ou baignoire-sabot dont le corps 1 de forme classique est divisé en deux parties 2, 3. Le plan de division est vertical et transversal à la longueur de la baignoire et passe par la partie plus profonde du corps de baignoire 1 (voir figure 3). La partie mobile 3 est reliée à la partie fixe 2 par un axe d'articulation 4 vertical situé sur un côte du corps de bia- gnoire 1. Un dispositif de fermeture 5 décrit plus en détail par la suite est prévu sur le côté opposé du corps de baignoire 1. L'étanchéité du corps de baignoire 1 à l'état fermé est assurée par un joint 6, par exemple en caoutchouc alvéolaire, comprimé lors de la fermeture du corps de baignoire 1 à l'aide du dispositif 5. Le joint 6 est fixé, par exemple par collage, sur un renforcement 7 prévu sur la partie 2 du corps de la baignoire 1, sur les côtés et le dessous. La partie 3 comporte un renforcement 8 correspondant. Ces renforcements sont destinés à procurer aux deux parties 2 et 3 une surface de contact suffisamment large et sont constitués, dans l'exemple représenté, par des cadres en bois.The opening bath illustrated by the drawing is a bath-tub or bath-tub whose body 1 of conventional shape is divided into two parts 2, 3. The division plane is vertical and transverse to the length of the bath and passes through the deeper part of bathtub body 1 (see figure 3). The movable part 3 is connected to the fixed part 2 by a vertical hinge pin 4 located on one side of the bathtub body 1. A closing device 5 described in more detail below is provided on the opposite side of the bathtub body 1. The tightness of the bathtub body 1 in the closed state is ensured by a seal 6, for example of cellular rubber, compressed during the closing of the bathtub body 1 using the device 5. The joint 6 is fixed, for example by gluing, on a reinforcement 7 provided on the part 2 of the body of the bath 1, on the sides and below. Part 3 includes a corresponding reinforcement 8. These reinforcements are intended to provide the two parts 2 and 3 with a sufficiently large contact surface and are constituted, in the example shown, by wooden frames.

On reconnait que le remplissage de la baignoire s'effectue à l'aide d'une robinetterie mélangeuse 9 classique du type mural et que la partie 2 du corps de baignoire 1 est équipée d'une bonde de vidange 10 avec trop-plein 11. La partie 3 comporte une bonde supplémentaire 12 dont la fonction sera décrite ci-après.It is recognized that the filling of the bath is carried out using a conventional mixing valve 9 of the wall type and that the part 2 of the bath body 1 is equipped with a drain 10 with overflow 11. Part 3 includes an additional drain 12 whose function will be described below.

La partie fixe 2 du corps de baignoire 1 repose sur le sol par son renforcement 7 et des pieds 13, tandis que la partie mobile 3 dont le renforcement 8 ne descend pas jusqu'au sol comporte une roulette 14 compensant le porte- à-faux lors du pivotement de la partie 3.The fixed part 2 of the bathtub body 1 rests on the ground by its reinforcement 7 and feet 13, while the movable part 3, the reinforcement 8 of which does not descend to the ground comprises a roller 14 compensating for the overhang when pivoting part 3.

Comme le montre en particulier la figure 3, le dispositif de fermeture 5 de la baignoire est constitué par deux loquets superposés du type à genouillère dont les parties dormantes 15 sont fixées sur le renforcement 7 de la partie fixe 2 du corps de la baignoire et dont les manettes de manoeuvre 16 sont reliées au renforcement 8 de la partie mobile 3 de manière à pouvoir pivoter autour d'un axe vertical. Pour faciliter la manoeuvre des deux loquets, leurs manettes de manoeuvre 16 sont reliées entre elles par une barre verticale 17 comportant une poignée de manoeuvre 18 à sa partie supérieure.As shown in particular in FIG. 3, the closure device 5 of the bathtub is constituted by two superimposed latches of the toggle type whose dormant parts 15 are fixed on the reinforcement 7 of the fixed part 2 of the body of the bathtub and whose the operating levers 16 are connected to the reinforcement 8 of the movable part 3 so as to be able to pivot about a vertical axis. To facilitate the operation of the two latches, their operating levers 16 are interconnected by a vertical bar 17 comprising an operating handle 18 at its upper part.

Afin d'empêcher le remplissage de la baignoire tant que cette dernière n'est pas complètement fermée, il est prévu, comme représenté sur la figure 2, un poussoir 19 faisant saillie, sous l'action d'un ressort, sur le renforcement 7 de la partie fixe 2, en direction du renforcement 8 de la partie mobile 3. Ce poussoir 19 agit sur une robinetterie d'arrêt 21 double, montée en amont de la robinetterie de remplissage 9 et fixée au renforcement 7. La robinetterie d'arrêt 21 comporte deux clapets couplés l'un pour commander l'arrivée d'eau chaude et l'autre pour commander l'arrivée d'eau froide à la robinetterie 9. Tant que le baignoire n'est pas complètement fermée, le poussoir 19 fait saillie sur le renforcement 7 et les deux clapets couplés de la robinetterie 21 sont fermés, de sorte qu'il n'est pas possible de faire couler de l'eau par la robinetterie 9. Ce n'est que lorsque le baignoire est complètement fermée, c'est-à-dire lorsque la partie mobile 3 est pressée contre la partie fixe 2 sous l'effet de serrage des loquets du dispositif de fermeture 5, le joint 6 étant comprimé, que le poussoir 19 appuyé contre le renforcement 8 de la partie mobile 3 se trouve repoussé, à l'encontre de la force de son ressort, dans le renforcement 7 de la partie fixe 2 et ouvre ainsi les deux clapets couplés de la robinetterie d'arrêt 21. Cette dernière libère ainsi l'arrivée de l'eau froide et de l'eau chaude à la robinetterie de remplissage 9.In order to prevent filling of the bathtub until the latter is not completely closed, there is provided, as shown in FIG. 2, a pusher 19 projecting, under the action of a spring, on the reinforcement 7 of the fixed part 2, in the direction of the reinforcement 8 of the movable part 3. This plunger 19 acts on a double stop valve 21, mounted upstream of the filling valve 9 and fixed to the reinforcement 7. The stop valve 21 includes two valves coupled one to control the arrival of hot water and the other to control the arrival of cold water to the valve 9. As long as the bathtub is not completely closed, the pusher 19 makes projection on the reinforcement 7 and the two coupled valves of the valve 21 are closed, so that it is not possible to run water through the valve 9. It is only when the bathtub is completely closed , that is to say when the movable part 3 is pressed against the fixed part 2 under the tightening effect of the latches of the closing device 5, the seal 6 being compressed, that the pusher 19 pressed against the reinforcement 8 of the movable part 3 is pushed back, against the force of its spring, in the reinforcement 7 of the fixed part 2 and thus opens the two coupled valves of the stop valve 21. The latter thus frees the arrival of cold water and hot water at the filling valve 9.

Pour améliorer la sensibilité du poussoir 19, c'est-à-dire assurer avec certitude que ce dernier n'ouvre la robinetterie d'arrêt 21 que lorsque la baignoire est complètement fermée, il est avantageux de placer la poussoir 19 sur le côté de la baignoire opposée à l'axe d'articulation 4.To improve the sensitivity of the plunger 19, that is to say ensure with certainty that the latter does not open the shut-off valve 21 until the bathtub is completely closed, it is advantageous to place the plunger 19 on the side of the bath opposite the hinge pin 4.

Afin d'empêcher que la baignoire ne puisse être ouverte tant qu'elle contient de l'eau, il est prévu un dispositif de sécurité coopérant avec le dispositif de fermeture 5. Ce dispositif de sécurité visible en particulier sur la figure 4 comprend un flotteur 22 se trouvant dans une cuve verticale 23 placée latéralement à côté de la partie mobile 3 du corps de baignoire 1. L'extrémité inférieure ouverte de la cuve 23 communique avec la bonde supplémentaire 12 par un conduit 24 passant en dessous du fond de la partie mobile 3. Ainsi, l'eau contenue dans la baignoire passe, suivant le principe des vases communicants, par la conduite 24 dans la cuve 23 et soulève le flotteur 22. Ce dernier est surmonté d'une tige verticale 25 qui coulisse librement dans un tube de guidage vertical 26 prolongeant la cuve 23 vers le haut. La cuve 23 avec son tube de guidage 26 est fixée au renforcement 8 de la partie mobile 3, de telle manière que le tube 26, et donc également la tige 25 qu'il contient, se trouve à faible distance du renforcement 8. Ce dernier porte, à proximité au-dessus de l'extrémité supérieure de tube de guidage 26, deux tronçons de cornière 27 dont les ailes saillantes sont horizontales et sont espacées verticalement. L'aile saillante de chaque cornière 27 est percée d'un trou d'un diamètre supérieur au diamètre de la tige 25. Les trous des deux tronçons de cornière 27 sont alignés avec l'axe de la tige 25.In order to prevent the bathtub from being able to be opened while it contains water, a safety device is provided which cooperates with the closing device 5. This safety device visible in particular in FIG. 4 comprises a float 22 located in a vertical tank 23 placed laterally next to the movable part 3 of the bathtub body 1. The open lower end of the tank 23 communicates with the additional drain 12 by a conduit 24 passing below the bottom of the part mobile 3. Thus, the water contained in the bath passes, according to the principle of communicating vessels, through line 24 in the tank 23 and lifts the float 22. The latter is surmounted by a vertical rod 25 which slides freely in a vertical guide tube 26 extending the tank 23 upwards. The tank 23 with its guide tube 26 is fixed to the reinforcement 8 of the movable part 3, so that the tube 26, and therefore also the rod 25 which it contains, is located a short distance from the reinforcement 8. The latter door, close above the upper end of guide tube 26, two sections of angle iron 27 whose projecting wings are horizontal and are spaced vertically. The projecting wing of each angle 27 is pierced with a hole with a diameter greater than the diameter of the rod 25. The holes of the two sections of angle 27 are aligned with the axis of the rod 25.

La barre verticale 17 reliant entre elles les manettes de manoeuvre 16 des deux loquets du dispositif de fermeture 5 de la baignoire est coudée à angle droit à son extrémité supérieure pour former une patte horizontale 29 percée d'un trou 30 d'un diamètre supérieur au diamètre de la tige 25. La position de l'axe de pivotement de la barre 17 par rapport à l'axe de la tige 25 et par rapport à l'axe du trou 30 sont choisies de manière qu'en position fermée du dispositif de fermeture 5, l'axe du trou 30 de la patte 29 se trouvant alors située entre les ailes saillantes des tronçons de cornière 27 soit aligné avec l'axe de la tige 25.The vertical bar 17 connecting together the operating levers 16 of the two latches of the closure device 5 of the bathtub is bent at right angles to its upper end to form a horizontal tab 29 pierced with a hole 30 with a diameter greater than the diameter of the rod 25. The position of the pivot axis of the bar 17 relative to the axis of the rod 25 and relative to the axis of the hole 30 are chosen so that in the closed position of the device closure 5, the axis of the hole 30 of the tab 29 then being located between the projecting wings of the sections of angle iron 27 is aligned with the axis of the rod 25.

Ainsi, dès que la baignoire fermée commence à être remplie d'eau, le flotteur 22 est soulevé de manière que la tige 25 traverse à la fois les trous 28 des ailes saillantes des tronçons de cornière 27 et le trou 30 de la patte 29, de sorte que cette dernière se trouve verrouillée en position et que, par conséquent, les loquets de fermeture ne puissent pas être ouverts par une manoeuvre intempestive de la poignée 18. La hauteur du flotteur 22 et de la tige 25 est choisie de telle manière que la patte 29 reste verrouillée par la tige 25 jusqu'à la vidange complète de la baignoire.Thus, as soon as the closed bathtub begins to be filled with water, the float 22 is raised so that the rod 25 passes through both the holes 28 of the projecting wings of the sections of angle iron 27 and the hole 30 of the tab 29, so that the latter is locked in position and that, consequently, the closing latches cannot be opened by an untimely operation of the handle 18. The height of the float 22 and of the rod 25 is chosen so that the lug 29 remains locked by the rod 25 until the bath is completely emptied.

Il va de soi que de nombreuses modifications et variantes peuvent être apportées à la baignoire telle que décrite ci-dessus et représentée sur le dessin annexé sans pour autant sortir du cadre de la présente invention. Ainsi, la baignoire pourrait être également du type à fond plat, bien qu'une baignoire-siège ou baignoire-sabot convienne mieux pour des personnes âgées ou handicapées.It goes without saying that many modifications and variations can be made to the bath as described above and shown in the accompanying drawing without departing from the scope of the present invention. Thus, the bathtub could also be of the flat bottom type, although a bathtub-bath or bath-tub is better suited for the elderly or disabled.

Le plan de division du corps de baignoire pourrait être ègalement situé plus près d'une extrémité de la baignoire, ce qui permettrait de réduire le profondeur du décrochement nécessaire dans le mur 20 afin de permettre le pivotement de la partie mobile.The dividing plane of the tub body could also be located closer to one end of the tub, which would make it possible to reduce the depth of the recess necessary in the wall 20 in order to allow the pivoting of the movable part.

Les renforcements prévus de part et d'autre du plan de division sur les deux parties du corps de baignoire pourraient être constitués par des rebords faisant partie intégrante des deux parties du corps de baignoire au lieu d'être constitué par des cadres rapportés en bois. Dans ce cas des trous ronds pourraient être prévus sur le rebord d'une des parties de la baignoire, de préférence de la partie mobile, le joint d'étanchéité en caoutchouc moulé comportant un nombre correspondant de tétons venant s'engager élastiquement par légère pression dans ces trous.The reinforcements provided on either side of the division plane on the two parts of the bathtub body could be constituted by flanges forming an integral part of the two parts of the bathtub body instead of being constituted by attached wooden frames. In this case round holes could be provided on the rim of one of the parts of the bathtub, preferably of the movable part, the molded rubber seal comprising a corresponding number of nipples coming to engage elastically by light pressure. in these holes.

Enfin, au lieu d'être formé de deux loquets du type à genouillère, le dispositif de fermeture de la baignoire pourrait comprendre des éléments différents à condition que ces derniers assurent le serrage nécessaire pour la compression du joint d'étanchéité.Finally, instead of being formed by two latches of the toggle type, the device for closing the bath could include different elements provided that the latter ensure the tightening necessary for the compression of the seal.

La baignoire qui est représentée à l'état nu sur le dessin, mais peut être garnie de façon usuelle d'un tablier sur les côtés apparents, peut être fabriquée en n'importe quelle matière usuelle pour baignoire, par exemple en fonte, en tôle, en matière plastique, bien qu'il soit avantageux de choisir une matière légère pour faciliter le pivotement de la partie mobile et éviter des efforts trop importants au niveau de l'axe d'articulation de cette dernière.The bathtub which is shown naked in the drawing, but can be provided in the usual way with an apron on the visible sides, can be made of any usual material for bathtub, for example cast iron, sheet metal , made of plastic, although it is advantageous to choose a light material to facilitate the pivoting of the movable part and avoid excessive forces at the level of the articulation axis of the latter.
