Description

DomaineField

La présente demande concerne un dispositif de fixation d'une partie arrière d'un abattant de cabinet d'aisance, ou W.-C.The present application relates to a device for fixing a rear part of a toilet seat, or toilet.

Exposé de l'art antérieurPresentation of the prior art

Un abattant de W.-C. comprend généralement une lunette et un couvercle qui sont montés de façon articulée sur une cuvette. La partie arrière de l'abattant peut être fixée à la cuvette par des boulons dont les écrous sont généralement situés sous le siège. Un inconvénient est que le montage et le démontage de l'abattant, notamment pour son entretien, nécessite le dévissage et vissage des boulons qui peuvent ne pas être facilement accessibles, la cuvette étant généralement disposée dans une pièce étroite. Un autre inconvénient est que le montage et le démontage de l'abattant pour son entretien requiert une manipulation de l'écrou et de la partie arrière de l'abattant qui peuvent être des pièces relativement peu nettoyées en raison de leur emplacement.A toilet seat usually includes a bezel and a lid that are hingedly mounted to a bowl. The rear part of the flap can be fixed to the bowl by bolts whose nuts are generally located under the seat. A disadvantage is that the assembly and disassembly of the flap, especially for its maintenance, requires the unscrewing and screwing bolts that may not be easily accessible, the bowl being generally disposed in a narrow room. Another disadvantage is that the assembly and disassembly of the flap for its maintenance requires manipulation of the nut and the rear part of the flap which can be relatively uncleaned parts because of their location.

Il existe des abattants de W.-C. dans lesquels la lunette et le couvercle de l'abattant sont montés pivotants sur un dispositif de fixation qui est fixé sur deux pions solidaires de la cuvette du W.-C. par un dispositif de verrouillage qui peut être libéré en appuyant sur un bouton situé à l'arrière ou à l'avant de l'abattant. Un inconvénient est que le montage et le démontage de l'abattant pour son entretien requiert généralement une manipulation de la partie arrière de l'abattant. Selon une variante, une protubérance peut être prévue à l'arrière de la lunette de façon à appuyer sur le bouton de déverrouillage lorsque la lunette est redressée. Un inconvénient est alors que le bouton de déverrouillage est actionné chaque fois que la lunette est relevée, ce qui peut entraîner un démontage accidentel et indésirable de l'abattant.There are toilet flaps in which the bezel and lid of the flap are pivotally mounted on a fixing device which is fixed on two pins integral with the bowl of the toilet by a locking device which can be released by pressing a button located at the rear or front of the flap. A disadvantage is that the assembly and disassembly of the flap for its maintenance generally requires manipulation of the rear part of the flap. Alternatively, a protrusion may be provided at the rear of the telescope so as to press the unlock button when the telescope is rectified. A disadvantage is that the unlocking button is actuated each time the bezel is raised, which can cause accidental and undesirable disassembly of the flap.

Il existe des abattants de W.-C. dans lesquels l'abattant comprend, en partie arrière, un aimant qui coopère avec un aimant prévu sur la cuvette pour fixer l'abattant à la cuvette. Un inconvénient est que, pour assurer une bonne fixation de l'abattant à la cuvette, la force d'attraction des aimants utilisés doit être relativement importante de sorte que le démontage de l'abattant peut requérir l'application d'une force importante.There are toilet flaps in which the flap comprises, in the rear part, a magnet which cooperates with a magnet provided on the bowl to fix the flap to the bowl. A disadvantage is that, to ensure a good fixing of the flap to the bowl, the attraction force of the magnets used must be relatively large so that the disassembly of the flap may require the application of a large force.

Il serait souhaitable que le montage et/ou le démontage d'un abattant de W.-C, notamment pour son entretien, puisse être réalisé de façon simple, sans effort excessif et sans avoir à manipuler la partie arrière de l'abattant.It would be desirable that the assembly and / or disassembly of a WC flap, in particular for its maintenance, can be carried out in a simple manner, without excessive effort and without having to manipulate the rear part of the flap.

La tête 82A et la gorge 47A du pion 28A sont conformées de façon que, alors que la tête 82A pénètre dans la gorge 47A du pion 28A, les efforts exercés par le pion 28A sur la tête 82A, lorsque le tube 24 est rapproché du siège, entraînent le pivotement de la pièce de verrouillage 40A dans le sens horaire autour de l'axe EA en figure 7A jusqu'à ce que la tête 82A sorte de la gorge 72A. Une fois que la tête 82A est sortie de la gorge 47A, celle-ci continue à glisser le long du corps cylindrique 44A du pion 28A. De plus, lorsque le tube 24 est rapproché du siège, les pions 28A, 28B exercent un appui sur les extrémités 48A, 48B des bras 30A, 30B. Ceci entraîne un pivotement des bras 30A, 30B autour des axes DA et DB et une mise en compression du ressort 32. Le bras 30A pivote dans le sens horaire en figure 7A. Le doigt 36A se déplace dans la rainure 56A de la came 38A, 38B depuis la position de verrouillage 68A jusqu'à la première position extrême supérieure 58A. Ceci se traduit en figure 7A par un pivotement de la came 38A dans le sens horaire autour de l'axe EA. Le pivotement de la pièce de verrouillage 40A entraîne la déformation de la patte flexible 86A contre le tube 24. Par simplicité, sur les figures 7A, 7B et 7C, les pattes flexibles 86A, 86B déformées sont représentées traversant le tube 24.The Figure 7A represents the locking device 18 after a user has, with respect to the position locked represented in figure 2 moved the tube 24 with respect to the seat downwards in the direction C, the tube 24 coming into substantially contact with the bases 42A, 42B of the pins 28A, 28B. This can be achieved by straightening the bezel and lid vertically and pressing the front part of the bezel and cover in direction C downwards. The head 82A and the groove 47A of the pin 28A are shaped so that, while the head 82A enters the groove 47A of the pin 28A, the forces exerted by the pin 28A on the head 82A, when the tube 24 is close to the seat , cause pivoting of the locking piece 40A clockwise around the axis EA in Figure 7A until the head 82A out of the groove 72A. Once the head 82A is out of the groove 47A, it continues to slide along the cylindrical body 44A of the pin 28A. In addition, when the tube 24 is close to the seat, the pins 28A, 28B exert a bearing on the ends 48A, 48B of the arms 30A, 30B. This causes pivoting of the arms 30A, 30B around the axes DA and DB and compression of the spring 32. The arm 30A pivots in a clockwise direction. Figure 7A . The finger 36A moves in the groove 56A of the cam 38A, 38B from the locking position 68A to the first upper end position 58A. This translates into Figure 7A by pivoting the cam 38A clockwise about the axis EA. The pivoting of the locking piece 40A causes deformation of the flexible tab 86A against the tube 24. For simplicity, on the Figures 7A, 7B and 7C , the deformed flexible tabs 86A, 86B are shown passing through the tube 24.

A titre de variante, le retrait de la tête 82A de la gorge 47A peut être obtenu par le pivotement de la came 38A qui peut entraîner un pivotement de la pièce de verrouillage 40A dans le sens horaire autour de l'axe EA en figure 7A de façon à dégager la tête 82A hors de la gorge 47A, par la mise en appui de l'ergot 74A contre la butée 84A de la pièce de verrouillage 40A.Alternatively, the removal of the head 82A from the groove 47A can be obtained by pivoting the cam 38A which can cause the locking member 40A to pivot in a clockwise direction about the axis EA. Figure 7A so as to disengage the head 82A from the groove 47A, by pressing the lug 74A against the stop 84A of the locking piece 40A.

La figure 7B représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 7A, commencé à éloigner le tube 24 par rapport au siège en le déplaçant vers le haut selon la direction C. Ceci peut être obtenu en exerçant une traction sur la partie avant de la lunette et du couvercle, en position redressée, selon la direction C vers le haut. A titre de variante, l'action du ressort 32 peut être suffisamment importante pour que l'utilisateur n'ait peu ou pas à tirer sur l'abattant. Sous l'action du ressort 32, le bras 30A a pivoté autour de l'axe DA dans le sens antihoraire en figure 7B. Le doigt 36A se déplace dans la rainure 56A de la came 38A depuis la position extrême supérieure 58A vers une position plus rapprochée de la position extrême extérieure 60A. La rainure 56A suit sensiblement entre la position extrême supérieure 58A et la position extrême extérieure 60A un arc de cercle d'axe DA. Ceci se traduit en figure 7B par un maintien sensiblement en position angulaire de la came 38A autour de l'axe EA et également de la pièce de verrouillage 40A sous l'action de l'ergot 74A de la came 38A en appui contre la butée 84A de la pièce de verrouillage 40A. La tête 82A de la pièce de verrouillage 40A ne pénètre donc pas dans la gorge 47A du pion 28A lorsqu'en raison du déplacement relatif entre le pion 28A et la pièce de verrouillage 40A, la tête 82A se trouve en vis-à-vis de la gorge 47A comme cela est représenté en figure 7B.The Figure 7B represents the locking device 18 after the user has, with respect to the position represented in Figure 7A , started moving the tube 24 away from the seat by moving it upwards in the direction C. This can be obtained by exerting a pull on the front part of the bezel and the lid, in the upright position, in the direction C towards the top. Alternatively, the action of the spring 32 may be large enough that the user has little or no to pull the lid. Under the action of the spring 32, the arm 30A has pivoted about the axis DA counterclockwise in Figure 7B . The finger 36A moves in the groove 56A of the cam 38A from the upper end position 58A to a position closer to the outer end position 60A. The groove 56A substantially follows between the upper end position 58A and the outer end position 60A a circular arc of axis DA. This translates into Figure 7B by substantially maintaining angular position of the cam 38A around the axis EA and also of the locking piece 40A under the action of the lug 74A of the cam 38A resting against the abutment 84A of the locking piece 40A . The head 82A of the locking piece 40A therefore does not penetrate the groove 47A of the pin 28A when, because of the relative displacement between the pin 28A and the locking piece 40A, the head 82A is opposite the the groove 47A as shown in Figure 7B .

La figure 7C représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 7B, continué à éloigner le tube 24 par rapport au siège en le déplaçant vers le haut selon la direction C. Sous l'action du ressort 32, le bras 30A a pivoté autour de l'axe DA dans le sens antihoraire en figure 7C. Le doigt 36A se déplace dans la rainure 56A de la came 38A jusqu'à la position extrême extérieure 60A. Ceci se traduit en figure 7C par un maintien sensiblement en position angulaire de la came 38A et également de la pièce de verrouillage 40A sous l'action de l'ergot 74A de la came 38A en appui contre la butée 84A de la pièce de verrouillage 40A.The Figure 7C represents the locking device 18 after the user has, with respect to the position represented in Figure 7B , continued to move the tube 24 relative to the seat by moving it upwards in the direction C. Under the action of the spring 32, the arm 30A has rotated about the axis DA in the counterclockwise direction. Figure 7C . The finger 36A moves in the groove 56A of the cam 38A to the outermost position 60A. This translates into Figure 7C by a substantially angular position of the cam 38A and also of the locking piece 40A under the action of the lug 74A of the cam 38A bears against the abutment 84A of the locking piece 40A.

La figure 7D représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 7C, continué à éloigner le tube 24 par rapport au siège en le déplaçant vers le haut selon la direction C. Sous l'action du ressort 32, le bras 30A a pivoté autour de l'axe DA, dans le sens antihoraire en figure 7D. Le doigt 36A se déplace dans la rainure 56A de la came 38A jusqu'à la position extrême inférieure 62A. Ceci se traduit en figure 7D par un pivotement de la came 38A dans le sens antihoraire autour de l'axe EA. Sous l'action de la patte flexible 86A, on obtient un pivotement de la pièce de verrouillage 40A dans le sens antihoraire autour de l'axe EA la maintenant en butée contre l'ergot 74A de la came 38A. La tête 82A, 82B se trouvant au niveau de la portion d'extrémité 46A, 46B du pion 28A, la tête 82A, 82B ne s'oppose pas au déplacement du pion 28A.The Figure 7D represents the locking device 18 after the user has, with respect to the position represented in Figure 7C , continued to move the tube 24 relative to the seat by moving it upwards in the direction C. Under the action of the spring 32, the arm 30A has pivoted about the axis DA, counterclockwise in Figure 7D . The finger 36A moves in the groove 56A of the cam 38A to the lower end position 62A. This translates into Figure 7D by pivoting the cam 38A counterclockwise about the axis EA. Under the action of the flexible tab 86A, a pivoting of the locking piece 40A in the counterclockwise direction about the axis EA is maintained in abutment against the lug 74A of the cam 38A. The head 82A, 82B being at the end portion 46A, 46B of the pin 28A, the head 82A, 82B does not oppose the movement of the pin 28A.

La figure 7E représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 7D, continué à éloigner le tube 24 par rapport au siège en le déplaçant vers le haut selon la direction C. Les pions 28A, 28B ont été complètement retirés du tube 24. L'abattant n'est plus fixé au siège.The figure 7E represents the locking device 18 after the user has, with respect to the position represented in Figure 7D , continued to move the tube 24 away from the seat by moving it upwards in the direction C. The pins 28A, 28B have been completely removed from the tube 24. The seat is no longer fixed to the seat.

Les figures 8A à 8D sont des vues analogues à la figure 2 du mode de réalisation du dispositif de verrouillage 18 à des étapes successives lors d'une opération de montage de l'abattant. Seuls les mouvements de rotation du bras 30A, de la came 38A et de la pièce de verrouillage 40A sont décrits, les mouvements de rotation du bras 30B, de la came 38B et de la pièce de verrouillage 40B étant symétriques par rapport à l'axe C.The Figures 8A to 8D are similar views to the figure 2 of the embodiment of the locking device 18 at successive stages during a mounting operation of the flap. Only the rotational movements of the arm 30A, the cam 38A and the locking piece 40A are described, the rotational movements of the arm 30B, the cam 38B and the locking piece 40B being symmetrical with respect to the axis vs.

Lorsque l'abattant n'est pas relié au siège, le dispositif de fixation 18 est dans la configuration représentée en figure 7E.When the lid is not connected to the seat, the fixing device 18 is in the configuration shown in FIG. figure 7E .

La figure 8A représente le dispositif de verrouillage 18 après que l'utilisateur a introduit les portions d'extrémité 46A, 46B des pions 28A, 28B dans les ouvertures 45A, 45B du tube 24 et a commencé à rapprocher le tube 24 par rapport au siège en le déplaçant vers le bas selon la direction C. Ceci peut être obtenu en exerçant une poussée sur la partie avant de la lunette et du couvercle, en position redressée, selon la direction C vers le bas. La figure 8A représente l'instant où les portions d'extrémité 46A, 46B des pions 28A, 28B viennent au contact des extrémités 48A, 48B des bras 30A, 30B.The figure 8A represents the locking device 18 after the user has introduced the end portions 46A, 46B pins 28A, 28B into the openings 45A, 45B of the tube 24 and began to bring the tube 24 relative to the seat in moving it downwards in the direction C. This can be obtained by exerting a thrust on the front part of the bezel and the lid, in the upright position, in the direction C downwards. The figure 8A represents the moment when the end portions 46A, 46B of the pins 28A, 28B come into contact with the ends 48A, 48B of the arms 30A, 30B.

La figure 8B représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 8A, continué à rapprocher le tube 24 par rapport au siège en le déplaçant vers le bas selon la direction C. Lorsque le tube 24 est rapproché du siège, les pions 28A, 28B exercent un appui sur les extrémités 48A, 48B des bras 30A, 30B. Ceci entraîne un pivotement des bras 30A, 30B autour des axes DA et DB et une mise en compression du ressort 32. Le bras 30A pivote dans le sens horaire en figure 8B. Le doigt 36A se déplace dans la rainure 56A de la came 38A depuis la position extrême inférieure 62A jusqu'à la position extrême intérieure 64A. Ceci se traduit en figure 8B par un pivotement de la came 38A dans le sens antihoraire autour de l'axe EA. Le glissement de la tête 82A sur la portion d'extrémité 46A du pion 28A entraîne un pivotement de la pièce de verrouillage 40A dans le sens horaire autour de l'axe EA en figure 8B. Le pivotement de la pièce de verrouillage 40A entraîne la déformation de la patte flexible 86A contre le tube 24. Par simplicité, sur les figures 8B, 8C et 8D, les pattes flexibles 86A, 86B déformées sont représentées traversant le tube 24.The Figure 8B represents the locking device 18 after the user has, with respect to the position represented in figure 8A , continued to bring the tube 24 relative to the seat by moving it down in the direction C. When the tube 24 is close to the seat, the pins 28A, 28B exert a bearing on the ends 48A, 48B of the arms 30A, 30B . This causes pivoting of the arms 30A, 30B around the axes DA and DB and compression of the spring 32. The arm 30A pivots in a clockwise direction. Figure 8B . The finger 36A moves in the groove 56A of the cam 38A from the lower end position 62A to the inner end position 64A. This translates into Figure 8B by pivoting the cam 38A counterclockwise about the axis EA. The sliding of the head 82A on the end portion 46A of the pin 28A causes a pivoting of the locking piece 40A in the clockwise direction around the axis EA. Figure 8B . The pivoting of the locking piece 40A causes deformation of the flexible tab 86A against the tube 24. For simplicity, on the Figures 8B, 8C and 8D , the deformed flexible tabs 86A, 86B are shown passing through the tube 24.

La figure 8C représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 8B, continué à rapprocher le tube 24 par rapport au siège en le déplaçant vers le bas selon la direction C, le tube 24 venant sensiblement au contact des embases 42A, 42B des pions 28A, 28B. Lors du déplacement relatif entre le pion 28A et la pièce de verrouillage 40A, la tête 82A pénètre dans la gorge 47A puis sort de la gorge 47A puis continue à glisser le long du corps cylindrique 44A du pion 28A. En outre, sous l'action du pion 28A sur l'extrémité 48A du bras 30A, le bras 30A a pivoté autour de l'axe DA dans le sens horaire en figure 8C mettant davantage en compression le ressort 32. Le doigt 36A se déplace dans la rainure 56A de la came 38A jusqu'à la deuxième position extrême supérieure 66A. Ceci entraîne un pivotement de la came 38A dans le sens horaire.The Figure 8C represents the locking device 18 after the user has, with respect to the position represented in Figure 8B , continued to bring the tube 24 relative to the seat by moving it down in the direction C, the tube 24 substantially in contact with the bases 42A, 42B pins 28A, 28B. During the relative movement between the pin 28A and the locking piece 40A, the head 82A enters the groove 47A then out of the groove 47A and continues to slide along the cylindrical body 44A of the pin 28A. In addition, under the action of the pawn 28A on the end 48A of the arm 30A, the arm 30A has rotated about the axis DA clockwise in Figure 8C further biasing the spring 32. The finger 36A moves in the groove 56A of the cam 38A to the second upper end position 66A. This causes the cam 38A to pivot in a clockwise direction.

A titre de variante, la forme de la rainure 56A peut être adaptée pour que la came 38A soit dans une position qui permette d'empêcher que la tête 82A de la pièce de verrouillage 40A ne pénètre dans la gorge 47A du pion 28A, en raison de la mise en appui de l'ergot 74A, 74B de la came 38A, 38B contre la butée 84A, 84B de la pièce de verrouillage 40A, 40B, lors du déplacement relatif du pion 28A par rapport au tube 24.Alternatively, the shape of the groove 56A may be adapted so that the cam 38A is in a position which prevents the head 82A of the locking piece 40A from entering the groove 47A of the pin 28A, due to the bearing of the lug 74A, 74B of the cam 38A, 38B against the stop 84A, 84B of the locking piece 40A, 40B, during the relative movement of the pin 28A relative to the tube 24.

La figure 8D représente le dispositif de verrouillage 18 après que l'utilisateur a, par rapport à la position représentée en figure 8C, commencé à éloigner le tube 24 par rapport au siège en le déplaçant vers le haut selon la direction C. Ceci peut être obtenu en exerçant une traction sur la partie avant de la lunette et du couvercle, en position redressée selon la direction C vers le haut. Sous l'action du ressort 32, le bras 30A a pivoté autour de l'axe DA dans le sens antihoraire en figure 8D. Le doigt 36A se déplace dans la rainure 56A de la came 38A depuis la deuxième position extrême supérieure 66A vers la position de verrouillage 68A. Ceci se traduit en figure 8D par un pivotement de la came 38A dans le sens horaire autour de l'axe EA. Sous l'action de la patte flexible 86A, on obtient un pivotement de la pièce de verrouillage 40A dans le sens antihoraire autour de l'axe EA ce qui fait pénétrer la tête 82A dans la gorge 47A du pion 28A, l'ergot 74A ne s'opposant pas au pivotement de la pièce de verrouillage 40A. Le dispositif de fixation 18 est alors verrouillé sur les pions 28A, 28B. A titre de variante, l'action du ressort 32 peut être suffisamment importante pour que l'utilisateur n'ait peu ou pas à tirer sur l'abattant.The figure 8D represents the locking device 18 after the user has, with respect to the position represented in Figure 8C , started moving the tube 24 away from the seat by moving it upwards in the direction C. This can be achieved by pulling on the front part of the bezel and lid, in the upright position in the direction C towards the high. Under the action of the spring 32, the arm 30A has pivoted about the axis DA counterclockwise in figure 8D . The finger 36A moves in the groove 56A of the cam 38A from the second upper end position 66A to the locking position 68A. This translates into figure 8D by pivoting the cam 38A clockwise about the axis EA. Under the action of the flexible lug 86A, a pivoting of the locking piece 40A is obtained in the counterclockwise direction about the axis EA, which causes the head 82A to penetrate into the groove 47A of the pin 28A, the lug 74A does not not opposing the pivoting of the locking piece 40A. The fastening device 18 is then locked on the pins 28A, 28B. Alternatively, the action of the spring 32 may be large enough that the user has little or no to pull the lid.

Lors d'une opération de démontage ou de montage, la portion bombée 78A, 78B de la patte flexible 76A, 76B de chaque came 38A, 38B frotte en continu sur le support 29. Cela assure que chaque came 38A, 38B reste sensiblement immobile, et ne bascule pas sous son propre poids, par exemple lorsque le doigt 36A porté par chaque bras 30A, 30B est dans la position extrême inférieure 62A.During a disassembly or assembly operation, the convex portion 78A, 78B of the flexible tab 76A, 76B of each cam 38A, 38B continuously rubs on the support 29. This ensures that each cam 38A, 38B remains substantially stationary, and does not rock under its own weight, for example when the finger 36A carried by each arm 30A, 30B is in the lower end position 62A.

Des modes de réalisation particuliers ont été décrits. Diverses variantes et modifications apparaîtront à l'homme de l'art. En particulier, les pattes flexibles 86A, 86B peuvent être remplacées par des ressorts hélicoïdaux.Particular embodiments have been described. Various variations and modifications will be apparent to those skilled in the art. In particular, the flexible tabs 86A, 86B may be replaced by coil springs.
