Description

La présente invention concerne une machine à laver le linge munie d'une manchette de liaison curve-carrosserie.The present invention relates to a washing machine with a curve-body connection cuff.

Une machine à laver le linge comprend habituellement une carrosserie dans laquelle est suspendue une cuve contenant un tambour à linge. Entre l'ouverture de la machine et l'ouverture de la cuve est montée une manchette souple qui assure à la fois un accès dans la cuve et une séparation étanche au liquide entre l'intérieur de la carrosserie et l'intérieur de la cuve. La cuve suspendue est soumise à des oscillations durant le fonctionnement de la machine et la manchette souple doit être solidement fixée à la carrosserie et à la cuve pour qu'elle puisse suivre la cuve dans ses mouvements et résister à tout arrachement provoqué par ces oscillations. Dans la machine à laver connue les rebords des deux extrémités de la manchette souples sont maintenus soit par des colliers de serrage montés autour de l'ouverture de la machine et l'ouverture de la cuve soit par des gorges de rétention formées autour de ces ouvertures dans lesquelles sont introduits de force ces rebords soit par des systèmes de fixation à vis et à barrettes ou cadres rigides. Les solutions connues utilisant des colliers ou des systèmes à vis et à barrettes ou cadres rigides sont coûteuses et exigent une mise en place manuelle relativement longue tandis que celles employant des gorges de retention ne sont pas pleinement satisfaisantes pour répondre aux exigences de tenue mécanique.A washing machine usually comprises a body in which is suspended a tub containing a washing drum. Between the opening of the machine and the opening of the tank is mounted a flexible cuff which provides both access to the tank and a liquid-tight separation between the interior of the bodywork and the interior of the tank. The suspended tank is subject to oscillations during the operation of the machine and the flexible cuff must be securely fixed to the body and the tank so that it can follow the tank in its movements and resist any tearing caused by these oscillations. In the known washing machine the edges of the two ends of the flexible cuff are maintained either by clamps mounted around the opening of the machine and the opening of the tank or by retention grooves formed around these openings into which these edges are forcibly introduced either by screw and bar fastening systems or rigid frames. Known solutions using collars or screw and bar or rigid frame systems are expensive and require relatively long manual positioning, while those using retention grooves are not fully satisfactory for meeting the mechanical strength requirements.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser une machine à laver le linge économique dans laquelle la manchette souple de liaison carrosserie- cuve est solidement fixée et assure une bonne étanchéité au liquide entre l'intérieur de la carrosserie et l'intérieur de la cuve, et entre l'intérieur de la cuve et l'extérieur de la machine, et la mise en place de cette manchette souple est facilement mécanisable.The aim of the present invention is to avoid these drawbacks, which makes it possible to produce an economical washing machine in which the flexible body-tank connection cuff is securely fixed and ensures good liquid tightness between the interior of the body and inside the tank, and between the inside of the tank and the outside of the machine, and the positioning of this flexible sleeve is easily mechanizable.

Selon l'invention, une machine à laver le linge munie d'une manchette de liaison cuve - carrosserie est caractérisée en ce qu'elle comprend au moins d'une part dans le pourtour du bord de l'ouverture de la machine et/ou de l'ouverture de la cuve, une rainure pourvue de mortaises espacées munies d'organe autobloquant antiretour, et d'autre part dans le long de l'extrémité supérieure et/ou inférieure de la manchette souple, un rebord saillant destiné à être monté dans cette rainure, et muni en premier lieu, de tenons espacés associés à ces mortaises et comportant chacun une gorge de réception de cet organe autobloquant antiretour, et en deuxième lieu, de lèvres d'étanchéité longitudinales parallèles souples dans les espaces situés au-dessus et entre deux tenons consécutifs.According to the invention, a washing machine with a tank-body connection sleeve is characterized in that it comprises at least on the one hand around the edge of the opening of the machine and / or of the opening of the tank, a groove provided with spaced mortises provided with self-locking non-return member, and on the other hand along the upper and / or lower end of the flexible cuff, a protruding rim intended to be mounted in this groove, and provided firstly with spaced studs associated with these mortises and each comprising a groove for receiving this self-locking non-return member, and secondly, with flexible parallel longitudinal sealing lips in the spaces above and between two consecutive studs.

Selon une caractéristique importante, la machine à laver le linge 1 comprend au moins d'une part dans le pourtour du bord de l'ouverture 4 de la machine et/ou de l'ouverture 8 de la cuve 6 de la machine, une rainure à parois lisses pourvue de mortaises espacées munies d'organe autobloquant antiretour et d'autre part dans le long de l'extrémité supérieure et/ou inférieure de la manchette souple 9 un rebord saillant destiné à être monté dans cette rainure, muni en premier lieu de tenons espacés associés aux mortaises de la rainure du bord de l'ouverture 4 de la machine et/ou de l'ouverture 8 de la cuve 6 de la machine, et comportant chacun une gorge de réception de cet organe autobloquant antiretour de ces mortaises et en deuxième lieu dans les espaces situés au-dessus et entre deux tenons consécutifs, de lèvres d'étanchéité longitudinales parallèles souples.According to an important characteristic, the washing machine 1 comprises at least on the one hand around the edge of the opening 4 of the machine and / or the opening 8 of the tank 6 of the machine, a groove with smooth walls provided with spaced mortises provided with self-locking non-return member and on the other hand along the upper and / or lower end of the flexible cuff 9 a protruding rim intended to be mounted in this groove, provided in the first place spaced studs associated with the mortises of the groove of the edge of the opening 4 of the machine and / or of the opening 8 of the tank 6 of the machine, and each comprising a groove for receiving this self-locking non-return member of these mortises and secondly, in the spaces above and between two consecutive tenons, of flexible parallel longitudinal sealing lips.

Selon une autre caractéristique, la machine à laver le linge 1 comprend d'une part dans le pourtour intérieur de l'extrémité inférieure de la manchette souple 9, une jupe 15 destinée à recouvrir la paroi intérieure du bord de l'ouverture 8 de la cuve 6 à fins d'esthétique et d'élimination de tout accrochage avec du linge introduit dans la cuve et de toute retenue de liquide ou produits lessiviels, et dans le pourtour intérieur de l'extrémité supérieure de la manchette souple 9, une lèvre d'étanchéité horizontalement saillante 16 et d'autre part dans la face intérieure de la porte pivotante 5 de la machine, une nervure d'étanchéité 17 encadrant l'ouverture 4 de la machine et coopérant avec cette lèvre saillante 16 de l'extrémité supérieure de la manchette souple 9 pour assurer l'étanchéité au liquide entre l'extérieur de la machine et l'intérieur de la cu ve.According to another characteristic, the washing machine 1 comprises on the one hand in the inner periphery of the lower end of the flexible cuff 9, a skirt 15 intended to cover the inner wall of the edge of the opening 8 of the tank 6 for aesthetic purposes and elimination of any catching with linen introduced into the tank and of any retention of liquid or detergents, and in the inner periphery of the upper end of the flexible cuff 9, a lip d horizontally projecting seal 16 and on the other hand in the inner face of the pivoting door 5 of the machine, a sealing rib 17 framing the opening 4 of the machine and cooperating with this projecting lip 16 of the upper end of the flexible sleeve 9 to seal the liquid between the outside of the machine and the inside of the tank.

Dans l'exemple illustré aux figures 1 à 4, la machine à laver 1 comprend dans le pourtour du bord de l'ouverture rectangulaire 4 de la machine, une rainure 19 à parois latérales interne 20 et externe 21 lisses, pourvue de mortaises espacées 22 qui s'ouvrent à travers la paroi de fond 23 et la paroi latérale externe 22 qui s'ouvrent à travers la paroi de fond 23 et la paroi latérale externe 21 de la rainure 19 et qui sont munies, chacun d'un organe autobloquant antiretour constitué par une languette élastique 24, inclinée vers l'intérieur de cette rainure 19 d'un angle alpha par rapport à la verticale, et faisant partie intégrante de cette paroi latérale externe 21 de la rainure 19.In the example illustrated in Figures 1 to 4, the washing machine 1 comprises in the periphery of the edge of the rectangular opening 4 of the machine, a groove 19 with internal side walls 20 and external 21 smooth, provided with spaced mortises 22 which open through the bottom wall 23 and the external side wall 22 which open through the bottom wall 23 and the external side wall 21 of the groove 19 and which are each provided with a self-locking non-return member constituted by an elastic tongue 24, inclined towards the inside of this groove 19 at an angle alpha with respect to the vertical, and forming an integral part of this external lateral wall 21 of the groove 19.

La manchette souple 9 comprend dans le pourtour de son extrémité supérieure 12, un rebord saillant souple 25 destiné à être monté dans la rainure 19 du bord de l'ouverture 4 de la machine. Ce rebord saillant 25 comprend sur sa longueur des tenons espacés 26 associés aux mortaises 22 de la rainure 19 du bord de l'ouverture 4 de la machine et destinés à retenir ce rebord saillant 25 dans cette rainure 19 et de ce fait, l'extrémité supérieure de la manchette souple 9, sur le bord de cette ouverture 4 de la machine. Les tenons espacés 26 comprennent chacun d'une part un corps à section transversale sensiblement en trapèze rectangle, ayant une face 27 coopérante avec la languette élastique 24, inclinée dans le même sens que celui de l'inclinaison de cette languette 24, et suivant un angle beta par rapport à la vertical, égal à l'angle alpha que fait cette languette 24 avec la verticale, et d'autre part à son extrémité libre un bourrelet terminal 28 qui définit avec cette face inclinée 27 une gorge 29 de réception de l'extrémité de cette languette 24 qui constitue l'organe autobloquant antiretour de la mortaise correspondante.The flexible cuff 9 comprises in the periphery of its upper end 12, a flexible projecting rim 25 intended to be mounted in the groove 19 of the edge of the opening 4 of the machine. This projecting rim 25 comprises along its length spaced tenons 26 associated with the mortises 22 of the groove 19 of the edge of the opening 4 of the machine and intended to retain this protruding rim 25 in this groove 19 and therefore the end upper of the flexible cuff 9, on the edge of this opening 4 of the machine. The spaced tenons 26 each comprise on the one hand a body with a cross section substantially in a rectangular trapezoid, having a face 27 cooperating with the elastic tongue 24, inclined in the same direction as that of the inclination of this tongue 24, and according to a angle beta with respect to the vertical, equal to the angle alpha that this tongue 24 makes with the vertical, and on the other hand at its free end a terminal bead 28 which defines with this inclined face 27 a groove 29 for receiving the 'end of this tongue 24 which constitutes the self-locking non-return member of the corresponding mortise.

Quand un tenon 28 de l'extrémité supérieure 12 de la manchette souple 9 est introduit dans une mortaise 22, la languette élastique 24 est déplacée, s'efface, laisse passer le bourrelet 28 et permet une mise en place de ce tenon 26. Etant donné que l'angle beta de la face inclinée 27 du tenon 26 est égal à l'angle alpha de l'inclinaison normale de la languette élastique 24, la languette 24 épouse cette face inclinée 27 lors d'une mise en place de ce tenon 26. La languette 24 est alors en place sur le tenon 26 pour le maintenir dans la rainure 19. Durant les oscillations de la cuve suspendue 6, la manchette 9 est soumise à des tractions qui tendent à tirer les tenons 26 hors des mortaises 22. Dans ce mouvement de retrait des tenons 26, les bourrelets 28 et les gorges 29 accrochent les extrémités libres des languettes 24 et les entrainent dans leur déplacement de manière que plus les tenons 26 sont tirés vers l'extérieur des mortaises, plus ces languettes 24 ferment automatiquement davantage les mortaises 22, augmentent en même temps leur pression sur ces tenons 26 et les empêchent de sortir de ces mortaises. L'extémité supérieure de la manchette souple 9 est ainsi solidement attachée au bord de l'ouverture 4 de la machine.When a tenon 28 of the upper end 12 of the flexible cuff 9 is introduced into a mortise 22, the elastic tongue 24 is displaced, disappears, lets the bead 28 pass and allows this tenon 26 to be put in place. given that the angle beta of the inclined face 27 of the tenon 26 is equal to the angle alpha of the normal inclination of the elastic tongue 24, the tongue 24 follows this inclined face 27 when this tenon is put in place 26. The tongue 24 is then in place on the tenon 26 to hold it in the groove 19. During the oscillations of the suspended tank 6, the cuff 9 is subjected to pulls which tend to pull the tenons 26 out of the mortises 22. In this movement of withdrawal of the pins 26, the beads 28 and the grooves 29 hook the free ends of the tabs 24 and entrain them in their displacement so that the more the tenons 26 are pulled towards the outside of the mortises, the more these tabs 24 automatically close the mortises 22 more, at the same time increase their pressure on these tenons 26 and prevent them from coming out of these mortises. The upper end of the flexible cuff 9 is thus securely attached to the edge of the opening 4 of the machine.

Dans les espaces situés au-dessus et entre deux tenons consécutifs 26, le rebord saillant souple 25 de la manchette 9 comprend des lèvres d'étanchéité longitudinales souples 31 qui épousent les moindres irrégularités de surface de la rainure 9 et augmentent ainsi l'intimité de contact entre ce rebord saillant 25 serré dans la rainure 19 et la paroi de celle-ci et y assurent une bonne étanchéité au liquide.In the spaces above and between two consecutive studs 26, the flexible projecting rim 25 of the cuff 9 comprises flexible longitudinal sealing lips 31 which conform to the slightest surface irregularities of the groove 9 and thus increase the intimacy of contact between this projecting rim 25 clamped in the groove 19 and the wall of the latter and ensure a good seal thereon to the liquid.

Les tenons 26 comprennent au niveau de leurs extrémités libres, dans leur partie diamètralement opposée à leurs bourrelets 28, des nervures longitudinales 33 destinées à être accrochées aux rebords des mortaises 22 lorsque les tenons 26 sont bien positionnés dans ces mortaises. Ces nervures 33 contribuent également à empêcher les tenons d'être retirés facilement des mortaises 22. Dans l'exemple illustré dans les figures 1 à 4, la cuve 6 comprend dans le pourtour de son ouverture rectangulaire 8, une rainure 36 à parois latérales interne 37 et externe 38 lisses, pourvue de mortaises espacées 39 qui s'ouvrent à travers le paroi de fond 40. Deux encoches verticales parallèles espacées 46 sont formées dans la paroi intérieure 37 de la rainure 36 au niveau des côtés latéraux de chacune des mortaises 39 pour rendre souple cette paroi 37 à l'endroit de cette mortaise et faciliter de ce fait le montage de l'extrémité inférieure de la manchette souple 9.The pins 26 comprise at their free ends, in their part diametrically opposite to their beads 28, longitudinal ribs 33 intended to be hung on the edges of the mortises 22 when the pins 26 are properly positioned in these mortises. These ribs 33 also contribute to preventing the studs from being easily removed from the mortises 22. In the example illustrated in FIGS. 1 to 4, the tank 6 comprises, in the periphery of its rectangular opening 8, a groove 36 with internal side walls 37 and external 38 smooth, provided with spaced mortises 39 which open through the bottom wall 40. Two spaced parallel vertical notches 46 are formed in the inner wall 37 of the groove 36 at the lateral sides of each of the mortises 39 to make this wall 37 flexible at the location of this mortise and thereby facilitate the mounting of the lower end of the flexible cuff 9.

La manchette souple 9 comprend dans le pourtour de son extrémité inférieure 13, un rebord saillant souple 41 destiné à être monté serré dans la rainure 36 du bord de l'ouverture 8 de la cuve 6. Ce rebord saillant 41 comprend sur sa longueur des tenons espacés 42 associés aux mortaises 39 de la rainure 36 et destinés à retenir ce rebord saillant 41 dans cette rainure et de ce fait l'extrémité inférieure de la manchette souple 9 sur le bord de l'ouverture 8 de cette cuve 6.The flexible cuff 9 comprises in the periphery of its lower end 13, a flexible projecting rim 41 intended to be fitted tightly in the groove 36 of the edge of the opening 8 of the tank 6. This projecting rim 41 includes tenons along its length spaced 42 associated with the mortises 39 of the groove 36 and intended to retain this protruding rim 41 in this groove and therefore the end bottom of the flexible cuff 9 on the edge of the opening 8 of this tank 6.

Les tenons espacés 42 comprennent chacun d'une part un corps à section transversale sensiblement rectangulaire, et d'autre part à son extrémité libre, un bourrelet périphérique saillant latéralement 43. Les bourrelets 43 s'accrochent au rebord des mortaises 39 quand les tenons 42 sont mis en place dans celles-ci, et empêchent ces tenons 42 d'être sortis de ces mortaises par simple et faible traction. L'extrémité inférieure de la manchette souple 9 est ainsi solidement attachée au bord de l'ouverture 8 de la cuve 6.The spaced studs 42 each comprise on the one hand a body with a substantially rectangular cross section, and on the other hand at its free end, a peripheral bead projecting laterally 43. The beads 43 hang on the edge of the mortises 39 when the tenons 42 are placed in them, and prevent these tenons 42 from being removed from these mortises by simple and weak traction. The lower end of the flexible cuff 9 is thus securely attached to the edge of the opening 8 of the tank 6.

Le rebord saillant souple 41 comprend des lèvres d'étanchéité longitudinales souples 45 qui épousent les moindres irrégularités de surface de la rainure 36 et renforcent ainsi l'intimité de contact entre ce rebord saillant 41 tassé dans cette rainure et la paroi de celle-ci et y assurent une bonne étanchéité au liquide.The flexible projecting rim 41 includes flexible longitudinal sealing lips 45 which conform to the slightest surface irregularities of the groove 36 and thus reinforce the contact intimacy between this projecting rim 41 packed in this groove and the wall of the latter and ensure good liquid tightness.

Dans une première variante de réalisation schématiquement et partiellement illustrée dans la figure 5, la machine à laver 1 comprend dans le pourtour du bord de l'ouverture 8 de la cuve 6 et/ou l'ouverture 4 de la machine une rainure 36 à parois latérales interne 37 et externe 38 lisses, pourvue de mortaises espacées 39 dans lesquelles, les deux encoches verticales parallèles espacées 46 retrouvées dans le premier exemple (figures 3 et 4) et formées au niveau des côtés latéraux de chacune des mortaises 39 dans le face extérieure de la paroi interne 37 de la rainure 36 sont respectivement remplacées par une encoche verticale 48 formée au niveau d'un premier côté latéral de chacune des mortaises 39, dans la paroi interne 37 de la rainure 36, et ouverte dans cette mortaise 39, et par une découpure transversale 49 dans cette paroi interne 37 de la rainure 36 au niveau du deuxième côté latéral de cette mortaise 39. La découpure 49 et l'encoche 48 transforment la paroi interne 37, au niveau de la mortaise 39, en un ergot élastique 52 qui sert d'organe autobloquant antiretour. L'ergot élastique 52 excerce une pression sur les tenon associé correspondant 42 du rebord saillant 41 et retient fermement ce rebord dans la rainure 36 par coïn cement de ce tenon 42 au niveau du bourrelet périphérique saillant 43 de ce dernier. L'encoche 48 donne une bonne étanchéité latérale à l'ergot 52 et facilite le montage du tenon 42 de la manchette 9 dans la mortaise 39 sans compromettre la rigidité verticale de cet ergot 52 qui s'oppose à un retrait inopiné de ce dernier tenon 42.In a first embodiment schematically and partially illustrated in FIG. 5, the washing machine 1 comprises, around the edge of the opening 8 of the tub 6 and / or the opening 4 of the machine, a groove 36 with walls lateral internal 37 and external 38 smooth, provided with spaced mortises 39 in which, the two parallel vertical spaced notches 46 found in the first example (Figures 3 and 4) and formed at the lateral sides of each of the mortises 39 in the outer face of the internal wall 37 of the groove 36 are respectively replaced by a vertical notch 48 formed at a first lateral side of each of the mortises 39, in the internal wall 37 of the groove 36, and open in this mortise 39, and by a transverse cutout 49 in this internal wall 37 of the groove 36 at the level of the second lateral side of this mortise 39. The cutout 49 and the notch 48 transform the internal wall 37, at the level mortise 39, in an elastic lug 52 which serves as a self-locking non-return member. The elastic lug 52 exerts pressure on the corresponding associated tenon 42 of the projecting rim 41 and firmly retains this rim in the groove 36 by means of a wedge cementing of this stud 42 at the projecting peripheral bead 43 of the latter. The notch 48 gives a good lateral tightness to the lug 52 and facilitates the mounting of the lug 42 of the cuff 9 in the mortise 39 without compromising the vertical rigidity of this lug 52 which is opposed to an unexpected withdrawal of the latter lug 42.

Dans une deuxième variante de réalisation schématiquement et partiellement illustrée dans la figure 6, la machine à laver 1 comprend dans le pourtour du bord de l'ouverture 8 de la cuve 6 et/ou de l'ouverture 4 de la machine, une rainure 36 pourvue de mortaises espacées 39 dans lesquelles les deux encoches verticales parallèles espacées 46 formées au niveau des côtés latéraux de chacune des mortaises 39 dans la face extérieure de la paroi interne 37 de la rainure 36, retrouvées dans le premier exemple (figures 3 et 4) sont respectivement remplacées d'une part par deux encoches verticales parallèles espacées 50 ouvertes dans la mortaise 39, formé es dans la paroi interne 37 de la rainure 36 au niveau des deux côtés latéraux de cette mortaise, et d'autre part par une découpure transversale 51 dans la paroi latérale interne 37 au niveau de la zone centrale de la mortaise 39, celle située entre ces deix encoches verticales parallèles 50. La découpure 51 transforme la paroi interne 37 de la rainure, au niveau de la mortaise 39, en deux ergots élastiques 53, 54 qui servent d'organe autobloquant antiretour. Ces ergots exercent une pression sur le tenon correspondant 42 du rebord saillant 41 et retient fermement ce rebord dans la rainure 36 par coïncement de ce tenon 42, au niveau de son bourrelet saillant 43. Les encoches 50 donnent une bonne élasticité latérale aux ergots 53, 54 et facilitent le montage du tenon 42 de la manchette 9 dans la mortaise 39 sans diminuer la rigidité verticale de ces ergots 53, 54 qui s'opposent à un retrait inopiné de ces tenons 42.In a second variant embodiment schematically and partially illustrated in FIG. 6, the washing machine 1 comprises, in the periphery of the edge of the opening 8 of the tank 6 and / or of the opening 4 of the machine, a groove 36 provided with spaced mortises 39 in which the two spaced parallel vertical notches 46 formed at the lateral sides of each of the mortises 39 in the outer face of the internal wall 37 of the groove 36, found in the first example (Figures 3 and 4) are respectively replaced on the one hand by two parallel spaced vertical notches 50 open in the mortise 39, formed es in the internal wall 37 of the groove 36 at the two lateral sides of this mortise, and on the other hand by a transverse cutout 51 in the internal lateral wall 37 at the level of the central zone of the mortise 39, that situated between these two parallel vertical notches 50. The cutout 51 transforms the wall internal 37 of the groove, at the level of the mortise 39, in two elastic lugs 53, 54 which serve as a self-locking non-return member. These lugs exert pressure on the corresponding tenon 42 of the protruding rim 41 and firmly retains this rim in the groove 36 by wedging this tenon 42 at its protruding bead 43. The notches 50 give good lateral elasticity to the lugs 53, 54 and facilitate the mounting of the tenon 42 of the cuff 9 in the mortise 39 without reducing the vertical rigidity of these lugs 53, 54 which oppose an unexpected withdrawal of these tenons 42.

Dans une troisième variante de réalisation schématiquement et partiellement illustrée dans la figure 7, dans chacun des tenons 26 du rebord saillant 25 de l'extrémité supérieure de la manchette 9, sur les deux côtés encadrant la gorge 29 de réception de l'organe autobloquant antiretour sont formées deux nervures verticales de positionnement 55 desintées à être accrochées aux rebords de la mortaise 22 situés sur les deux côtés latéraux de cet organe autobloquant antiretour constitué par la languette 24 lorsque le tenon 26 est correctement positionné dans cette mortaise 22.In a third alternative embodiment schematically and partially illustrated in FIG. 7, in each of the pins 26 of the projecting rim 25 of the upper end of the cuff 9, on the two sides framing the groove 29 for receiving the self-locking non-return member are formed two vertical ribs of positioning 55 intended to be attached to the edges of the mortise 22 located on the two lateral sides of this self-locking non-return member constituted by the tongue 24 when the tenon 26 is correctly positioned in this mortise 22.

Dans une quatrième variante de réalisation illustrée dans la figure 8, la machine à laver 1 comprend dans le pourtour du bord de l'ouverture 4 de la machine et/ou l'ouverture 8 de la cuve 6, une rainure 19 à parois latérales interne 20 et externe 21 lisses, pourvue de mortaises espacées 57 qui s'ouvrent à travers ses deux parois latérales interne 20 et externe 21 et sa paroi de fond 23 et qui sont munies chacune d'un organe autobloquant antiretour constitué par deux languettes latérales opposées symétriques élastiques 59, 60, inclinées et convergentes vers l'intérieur de cette rainure 19 respectivement suivant un angle alpha par rapport à la verticale, et faisant partie intégrante respectivement des parois interne 20 et externe 21 de cette rainure.In a fourth embodiment illustrated in FIG. 8, the washing machine 1 comprises, in the periphery of the edge of the opening 4 of the machine and / or the opening 8 of the tank 6, a groove 19 with internal side walls 20 and external 21 smooth, provided with spaced mortises 57 which open through its two internal side walls 20 and external 21 and its bottom wall 23 and which are each provided with a self-locking non-return member constituted by two opposite symmetrical lateral tabs elastic 59, 60, inclined and converging towards the inside of this groove 19 respectively at an angle alpha relative to the vertical, and forming an integral part respectively of the internal walls 20 and external 21 of this groove.

Dans cette variante de réalisation, la manchette souple 9 comprend dans le pourtour de l'extrémité supérieure 12 et/ou inférieur 13, un rebord saillant souple 25 pourvu sur sa longueur de tenons espacés 61 associés aux mortaises 57 de la rainure 19 du bord de l'ouverture 4 de la machine et/ou de l'ouverture 8 de la cuve 6 et destinés à retenir ce rebord saillant 25 dans cette rainure 19. Les tenons espacés 61 comprennent chacun d'une part un corps à section transversale sensiblement en trapèze isocèle ayant deux faces opposées symétriques 63, 64 coopérantes avec les deux languettes latérales élastiques opposées symétriques 59, 60, inclinées respectivement dans les mêmes sens que ceux des inclinaisons des languettes opposées symétriques 59, 60 et respectivement suivant un angle beta par rapport à la verticale, inférieur à l'angle alpha que font les languettes 59, 60 avec la verticale, et d'autre part à son extrémité libre, deux bourrelets terminaux 65, 66 qui définissent respectivement avec ces deux faces inclinées 63, 64, deux gorges 67, 68 de réception des extrémités de ces languettes servant d'organe autobloquant antiretour.In this alternative embodiment, the flexible cuff 9 comprises in the periphery of the upper end 12 and / or lower 13, a flexible projecting rim 25 provided along its length with spaced studs 61 associated with the mortises 57 of the groove 19 of the edge of the opening 4 of the machine and / or the opening 8 of the tank 6 and intended to retain this protruding rim 25 in this groove 19. The spaced studs 61 each comprise on the one hand a body with a substantially trapezoidal cross section isosceles having two symmetrical opposite faces 63, 64 cooperating with the two symmetrical opposite elastic lateral tongues 59, 60, inclined respectively in the same directions as those of the inclinations of the symmetrical opposite tongues 59, 60 and respectively at a beta angle with respect to the vertical , less than the angle alpha made by the tongues 59, 60 with the vertical, and on the other hand at its free end, two end beads 65, 66 which respectively define with these two inclined faces 63, 64, two grooves 67, 68 for receiving the ends of these tongues serving as a self-locking non-return member.

Quand un tenon 61 du rebord saillant 25 de la manchette souple 9 est introduit dans une mortaise 57, les languettes latérales élastiques symétriques 59, 60 sont déplacées, laissent passer les bourrelets 65, 66 et permettent une mise en place de ce tenon 61.When a tenon 61 of the projecting rim 25 of the flexible cuff 9 is introduced into a mortise 57, the symmetrical elastic lateral tabs 59, 60 are displaced, allow the beads 65, 66 to pass and allow this tenon 61 to be put in place.

Etant donné que l'angle beta des faces inclinées symétriques 63, 64 du tenon 61 est égal à l'angle alpha des inclinaisons normales des languettes élastiques symétriques 59, 60, ces languettes 59, 60 épousent ces faces inclinées lors d'une mise en place de ce tenon 61. Les languettes symétriques 59, 60 sont alors en place sur ce tenon 61 pour le maintenir dans la rainure 19. Durant les oscillations de la cuve suspendue 6, la manchette 9 est soumise à des tractions qui tendent à retirer les tenons 61 hors des mortaises 57. Dans ce mouvement de retrait des tenons 61, les bourrelets terminaux 65, 66 de ces tenons accrochent les extrémités libres des languettes symétriques 59, 60 et les entrainent dans leur déplacement de manière que plus les tenons 61 sont tirés vers l'extérieur des mortaises 57, plus ces languettes se rapprochent l'une de l'autre, ferment davantage ces mortaises 57, augmentent leur pression sur ces tenons et les empêchent de sortir de ces mortaises. L'extrémité de la manchette souple 9 est ainsi solidement attachée au bord de l'ouverture 4 de la machine et/ou l'ouverture 8 de la cuve 6.Given that the angle beta of the symmetrical inclined faces 63, 64 of the stud 61 is equal to the angle alpha of the normal inclinations of the symmetrical elastic tongues 59, 60, these tongues 59, 60 follow these inclined faces during setting place of this tenon 61. The symmetrical tabs 59, 60 are then in place on this tenon 61 to hold it in the groove 19. During the oscillations of the suspended tank 6, the cuff 9 is subjected to pulls which tend to withdraw the tenons 61 outside the mortises 57. In this movement of withdrawal of the tenons 61, the end beads 65, 66 of these tenons hook the free ends of the symmetrical tabs 59, 60 and cause them to move so that the more the tenons 61 are pulled towards the outside of the mortises 57, the more these tongues come closer to one another, more close these mortises 57, increase their pressure on these tenons and prevent them from coming out of these mortises. The end of the flexible cuff 9 is thus securely attached to the edge of the opening 4 of the machine and / or the opening 8 of the tank 6.

Dans une cinquième variante de réalisation illustrée dans les figures 9 et 10, la machine à laver 1 comprend dans le pourtour de l'ouverture rectangulaire 4 de la machine et/ou l'ouverture rectangulaire 8 de la cuve 6, une rainure 19 à parois latérales interne 20 et externe 21 lisses, pourvue de mortaises espacées 70 qui s'ouvrent à travers la paroi de fond 23 de la rainure 19 et qui sont munies chacune d'un organe autobloquant antiretour constitué par deux languettes longitudinales opposées symétriques 72, 73 inclinées et convergentes vers le plan transversal de symétrie 74 de ces mortaises, respectivement suivant un angle alpha par rapport à la verticale ou à ce plan transversal de symétrie, et faisant partie intégrante de la paroi de fond 23 de cette rainure 19.In a fifth variant embodiment illustrated in FIGS. 9 and 10, the washing machine 1 comprises, in the periphery of the rectangular opening 4 of the machine and / or the rectangular opening 8 of the tank 6, a groove 19 with walls lateral internal 20 and external 21 smooth, provided with spaced mortises 70 which open through the bottom wall 23 of the groove 19 and which are each provided with a self-locking non-return member constituted by two opposite symmetrical longitudinal tongues 72, 73 inclined and converging towards the transverse plane of symmetry 74 of these mortises, respectively at an angle alpha with respect to the vertical or to this transverse plane of symmetry, and forming an integral part of the bottom wall 23 of this groove 19.

Dans cette variante de réalisation, la manchette souple 9 comprend dans le pourtour de l'extrémité supérieure 12 et/ou inférieure 13 un rebord saillant souple 25 pourvu sur sa longueur, de tenons espacés 76 associés aux mortaises 70 de la rainure 19 du bord de l'ouverture 4 de la machine et/ou de l'ouverture 8 de la cuve 6 et destinés à retenir ce bord saillant 25 dans cette rainure 19. Les tenons espacés 76 comprennent chacun d'une part un corps à section longitudinale sensiblement en trapèze isocéle ayant deux faces opposées symétriques 77, 78 coopérantes avec des languettes longitudinales symétriques élastiques 72, 73, respectivement inclinées dans les mêmes sens que ceux des inclinaisons de ces languettes opposées symétriques 72, 73, et suivant respectivement un angle beta par rapport à la verticale, égal à l'angle alpha que font les languettes 72, 73 avec la verticale, et d'autre part à son extrémité libre, deux bourrelets terminaux 79, 80 qui définissent respectivement avec ces faces inclinées 77, 78, deux gorges 81, 82 de réception des extrémités de ces languettes qui servent d'organe autobloquant antiretour.In this alternative embodiment, the flexible cuff 9 comprises in the periphery of the upper end 12 and / or lower 13 a flexible projecting rim 25 provided along its length with spaced studs 76 associated with the mortises 70 of the groove 19 of the edge of the opening 4 of the machine and / or the opening 8 of the tank 6 and intended to retain this projecting edge 25 in this groove 19. The spaced studs 76 each comprise on the one hand a body with a longitudinal section substantially in trapezoid isocele having two opposite symmetrical faces 77, 78 cooperating with elastic symmetrical longitudinal tongues 72, 73, respectively inclined in the same directions as those of the inclinations of these opposite symmetrical tongues 72, 73, and respectively at a beta angle with respect to the vertical , equal to the angle alpha made by the tongues 72, 73 with the vertical, and on the other hand at its free end, two end beads 79, 80 which respectively define with these f inclined aces 77, 78, two grooves 81, 82 for receiving the ends of these tongues which serve as a self-locking non-return member.

Quand un tenon 76 rebord saillant 25 de la manchette souple 9 est introduit dans une mortaise 70, les languettes longitudinales élastiques 72, 73 sont déplacées, laissent passer les bourrelets 79, 80 et permettent une mise en place de ce tenon 76. Etant donné que l'angle beta des faces inclinées 77, 78 du tenon 76 est égal à l'angle alpha, les languettes élastiques 72, 73 épousent ces faces inclinées lors d'une mise en place de ce tenon 76. Les languettes symétriques 72, 73 sont alors en place sur ce tenon 76 pour le maintenir dans la rainure 19. Durant les oscillations de la cuve suspendue 6, la manchette 9 est soumise à des tractions qui tendent à arracher les tenons 76 des mortaises 70. Dans ce mouvement de retrait des tenons 76, les bourrelets terminaux 79, 80 de ces tenons accrochent les extrémités libres des languettes symétriques élastiques 72, 73 et les entrainent dans leur déplacement de manière que plus les tenons 76 sont tirés vers l'extérieur des mortaises 70, plus ces languettes se rapprochent l'une de l'autre, ferment davantage ces mortaises 70, augmentent leur pression sur ces tenon 76 et les empêchent de sortir de ces mortaises 70.When a tenon 76 protruding rim 25 of the flexible cuff 9 is introduced into a mortise 70, the elastic longitudinal tabs 72, 73 are displaced, allow the beads 79, 80 to pass and allow this tenon 76 to be put in place. the angle beta of the inclined faces 77, 78 of the tenon 76 is equal to the angle alpha, the elastic tabs 72, 73 conform to these inclined faces during the positioning of this tenon 76. The symmetrical tongues 72, 73 are then in place on this tenon 76 to hold it in the groove 19. During the oscillations of the suspended tank 6, the cuff 9 is subjected to pulls which tend to tear the tenons 76 from the mortises 70. In this movement of withdrawal of the tenons 76, the end beads 79, 80 of these tenons hook the free ends of the elastic symmetrical tabs 72, 73 and cause them to move so that the more the tenons 76 are pulled outwards from the mortises 70, the more these lang uettes move closer to each other, close more these mortises 70, increase their pressure on these tenons 76 and prevent them from coming out of these mortises 70.

Les extrémités supérieures 12 et inférieures 13 de la manchette 9 et les bords des ouvertures 4 de la machine et 8 de la cuve ont ainsi une structur e simple, et sont faciles à réaliser et à assembler aussi bien manuellement que mécaniquement. Une économie de matière, de temps et de main d'oeuvre qui en résulte est appréciable dans la fabrication de cette machine à laver le linge. The upper 12 and lower 13 ends of the cuff 9 and the edges of the openings 4 of the machine and 8 of the tank thus have a simple structure, and are easy to produce and to assemble both manually and mechanically. A saving of material, time and labor which results therefrom is appreciable in the manufacture of this washing machine.
