La présente invention se rapporte à un appareil de repassage comportant une cuve pour la production de vapeur sous pression et se rapporte plus particulièrement à un appareil de repassage dans lequel la cuve est munie d'un orifice de remplissage fermé par un bouchon amovible.The present invention relates to an ironing apparatus comprising a vessel for the production of steam under pressure and relates more particularly to an ironing apparatus in which the tank is provided with a filling orifice closed by a removable plug.
Il est connu des appareils de repassage comportant une cuve pour la production de vapeur sous pression munie d'un orifice de remplissage fermé par un bouchon amovible venant se visser sur l'orifice de remplissage. Cependant, de tels bouchons munis d'un filetage présentent l'inconvénient d'être relativement long à visser et à dévisser et donnent accès à un petit orifice de remplissage, rendant pénible l'opération de remplissage de la cuve. De plus, de tels bouchons ne protègent pas le consommateur contre le risque d'ouverture du bouchon alors que la cuve est encore sous pression.It is known ironing appliances comprising a tank for the production of pressurized steam provided with a filling port closed by a removable cap which is screwed on the filling orifice. However, such plugs provided with a thread have the disadvantage of being relatively long to screw and unscrew and give access to a small filling orifice, making it difficult the filling operation of the tank. In addition, such caps do not protect the consumer against the risk of opening the cap while the tank is still under pressure.
Il est connu de remédier à ce dernier inconvénient en intégrant un système de sécurité dans le bouchon, un bouchon est par exemple décrit dans le brevet EP 337 528, cependant ces bouchons sont très complexes et restent pénibles à dévisser. Aussi, un but de la présente invention est de remédier à ces inconvénients en proposant un appareil de repassage muni d'un bouchon à ouverture rapide procurant une grande ergonomie d'utilisation. Un autre but de la présente invention est de proposer un appareil de repassage à la sécurité améliorée.It is known to remedy this last drawback by integrating a security system in the cap, a plug is for example described in EP 337 528, however these plugs are very complex and are painful to unscrew. Also, an object of the present invention is to overcome these disadvantages by providing an ironing apparatus with a quick-opening cap providing great ergonomics of use. Another object of the present invention is to provide an ironing apparatus with improved safety.
A cet effet, l'invention a pour objet un appareil de repassage comportant une cuve pour la production de vapeur sous pression munie d'un orifice de remplissage fermé par un bouchon amovible, caractérisé en ce que le bouchon est immobilisé en regard de l'orifice de remplissage par des moyens de fixation permettant l'ouverture et/ou la fermeture rapide du bouchon par rotation de ce dernier sur moins d'un tour. Selon une autre caractéristique de l'appareil de repassage selon l'invention, le bouchon est accouplé à l'extrémité d'une tubulure entourant l'orifice de remplissage au moyen d'une fixation de type baïonnette, le bouchon comportant une mâchoire comprenant des griffes venant s'engager sous des rampes formées à l'extrémité de la tubulure. Selon encore une autre caractéristique de l'invention, le diamètre de l'orifice de remplissage est compris entre 20mm et 40mm.For this purpose, the subject of the invention is an ironing apparatus comprising a vessel for the production of pressurized steam provided with a filling orifice closed by a removable plug, characterized in that the plug is immobilized opposite the filling port by fastening means allowing the opening and / or quick closing of the cap by rotation of the latter on less than one turn. According to another characteristic of the ironing apparatus according to the invention, the plug is coupled to the end of a pipe surrounding the filling orifice by means of a bayonet-type fastener, the plug comprising a jaw comprising claws coming to engage under ramps formed at the end of the tubing . According to yet another characteristic of the invention, the diameter of the filling orifice is between 20 mm and 40 mm.
Une telle caractéristique permet un remplissage ou une vidange rapide de la cuve tout en conservant des efforts acceptables sur les moyens de fixation du bouchon. Selon une autre caractéristique de l'invention, la cuve, la tubulure de remplissage et la mâchoire sont en inox.Such a characteristic allows a filling or a rapid emptying of the tank while maintaining acceptable efforts on the fastening means of the cap. According to another characteristic of the invention, the tank, the filler neck and the jaw are made of stainless steel.
Selon une autre caractéristique de l'invention, la tubulure de remplissage et la mâchoire en inox reçoivent un traitement de surface en étant recouvertes de Téflon ou immergées dans un bain comprenant de l'étain. Un tel traitement permet de diminuer le frottement entre les griffes et les rampes et réduire ainsi l'effort nécessaire à l'ouverture et à la fermeture du bouchon.According to another characteristic of the invention, the filling pipe and the stainless steel jaw are surface treated by being covered with Teflon or immersed in a bath comprising tin. Such a treatment makes it possible to reduce the friction between the claws and the ramps and thus to reduce the effort required to open and close the plug.
Selon encore une autre caractéristique de l'invention, l'étanchéité du bouchon est réalisée au moyen d'un joint porté par un noyau qui est mobile en rotation par rapport à la mâchoire du bouchon. Une telle caractéristique permet de limiter l'usure du joint par frottement.According to yet another characteristic of the invention, the sealing of the plug is performed by means of a seal carried by a core which is rotatable relative to the plug jaw. Such a characteristic makes it possible to limit the wear of the seal by friction.

Une telle caractéristique permet d'avoir un joint ayant une bonne élasticité et une grande résistance à la vapeur.Such a characteristic makes it possible to have a seal having a good elasticity and a high resistance to steam.
Selon une autre caractéristique de l'invention, l'appareil comporte une base renfermant la cuve et des moyens de liaison reliant le bouchon à la base lorsque le bouchon est dans une position ouverte permettant l'accès à l'orifice de remplissage.According to another characteristic of the invention, the apparatus comprises a base enclosing the tank and connecting means connecting the cap to the base when the cap is in an open position allowing access to the port of filling.
Une telle caractéristique permet d'éviter la chute du bouchon lorsqu'il est ôté de l'orifice de remplissage.Such a characteristic makes it possible to prevent the cap from falling when it is removed from the filling orifice.
Selon une autre caractéristique de l'invention, les moyens de liaison sont constitués par un bras articulé reliant le bouchon à la base.According to another characteristic of the invention, the connecting means are constituted by an articulated arm connecting the plug to the base.
Un tel bras présente l'avantage d'assurer le positionnement correct du bouchon en regard de l'orifice de remplissage lors de la fermeture du bouchon.Such an arm has the advantage of ensuring the correct positioning of the stopper facing the filling orifice when closing the stopper.
Selon une autre caractéristique de l'invention, le bouchon comporte une poignée faisant saillie radialement au corps du bouchon. Selon encore une autre caractéristique de l'invention, la poignée vient actionner un interrupteur de sécurité lorsque le bouchon est correctement fermé.According to another characteristic of the invention, the cap comprises a handle projecting radially from the body of the cap. According to yet another characteristic of the invention, the handle actuates a safety switch when the cap is properly closed.
Une telle caractéristique permet d'augmenter la sécurité d'utilisation de l'appareil en empêchant le fonctionnement de l'appareil et notamment l'activation des moyens de chauffage de la cuve lorsque le bouchon n'est pas correctement fermé.Such a feature increases the safety of use of the apparatus by preventing the operation of the apparatus and in particular the activation of the heating means of the tank when the cap is not properly closed.
Selon une autre caractéristique de l'invention, l'appareil comporte, en fin de course d'ouverture du bouchon, des moyens de guidage soulevant le bouchon lorsque ce dernier n'est plus retenu sur l'orifice de remplissage par les moyens de fixation. De tels moyens de guidage permettent de créer un couple de soulèvement du bouchon à la fin de son ouverture de manière à contrer un éventuel effet ventouse du bouchon créé par une dépression à l'intérieur de la cuve.According to another characteristic of the invention, the apparatus comprises, at the end of the opening stroke of the cap, guide means raising the cap when the latter is no longer retained on the filling orifice by the fastening means . Such guiding means allow to create a lifting torque of the plug at the end of its opening so as to counteract any suction effect of the plug created by a depression inside the tank.

Conformément aux figures 2 et 3, le bras articulé 6 comporte un corps 61 allongé, de section sensiblement rectangulaire, qui est muni à l'une de ses extrémités d'un axe d'articulation 62 monté pivotant en bordure du boîtier 10, l'autre extrémité supportant une bague circulaire 63 recevant le bouchon 5.According to FIGS. 2 and 3, the articulated arm 6 comprises an elongate body 61 of substantially rectangular cross-section, which is provided at one of its ends with a hinge pin 62 pivotally mounted at the edge of the housing 10, another end supporting a circular ring 63 receiving the cap 5.
Plus particulièrement selon l'invention, le bouchon 5 est un bouchon à ouverture rapide dont l'ouverture s'effectue par rotation du bouchon sur moins d'un tour et préférentiellement par rotation du bouchon entre 1/8 et 1/2 de tour, de manière avoir une grande ergonomie d'utilisation. Dans l'exemple illustré sur la figure, le bouchon est monté rotatif sur le bras et peut pivoter d'un tiers de tour entre une position déverrouillée illustrée sur la figure 1 B et une position verrouillée illustrée sur la figure 1C.More particularly according to the invention, the stopper 5 is a quick-opening stopper, the opening of which is effected by rotation of the stopper on less than one turn and preferably by rotation of the stopper between 1/8 and 1/2 of a turn, to have a great ergonomics of use. In the example illustrated in the figure, the plug is rotatably mounted on the arm and is rotatable one-third of a turn between an unlocked position shown in Figure 1B and a locked position shown in Figure 1C.
Le bouchon 5 comporte un couvercle 50 présentant un corps sensiblement circulaire d'un diamètre de l'ordre de 6 cm venant coiffer la bague 63, le bord supérieur de cette dernière comprenant un diamètre restreint formant un épaulement 63A sous lequel vient s'engager un disque 51. Le disque 51 pivote à l'intérieur de la bague circulaire 63 et présente un bord périphérique dont la surface supérieure vient à proximité de Pépaulement 63A de la bague circulaire.The plug 5 comprises a cover 50 having a substantially circular body of a diameter of about 6 cm to cap the ring 63, the upper edge of the latter comprising a restricted diameter forming a shoulder 63A under which is engaged a The disk 51 pivots inside the circular ring 63 and has a peripheral edge whose upper surface comes close to the shoulder 63A of the circular ring.
Le disque 63 et le couvercle 50 sont réalisés en matériau polyamide et sont rendus solidaires l'un de l'autre par des pions d'assemblage 52, portés par le disque 51 , qui sont emmanchés dans des tubes 5OA portés par le couvercle 50. L'accouplement du bouchon 5 sur la tubulure de remplissage 4 est assuré par une mâchoire 53 en matériau inox écroui d'une épaisseur de 2,6mm qui est disposée entre le couvercle 50 et le disque 51. La mâchoire 53 comporte deux griffes 53A symétriques traversant deux échancrures latérales 51 A du disque et venant s'engager sous des rampes 40 formées par un bord rabattu à l'extrémité de la tubulure de remplissage 4 pour réaliser une liaison de type baïonnette, le bord rabattu comportant localement deux découpes 41 pour le passage des griffes 53A.The disc 63 and the cover 50 are made of polyamide material and are secured to one another by assembly pins 52, carried by the disc 51, which are fitted into tubes 50A carried by the cover 50. The coupling of the plug 5 on the filler neck 4 is provided by a jaw 53 made of hardened stainless steel material with a thickness of 2.6 mm which is disposed between the cover 50 and the disc 51. The jaw 53 comprises two symmetrical claws 53A passing through two lateral indentations 51A of the disc and engaging under ramps 40 formed by a folded edge at the end of the filler neck 4 to make a bayonet type connection, the folded edge locally comprising two cutouts 41 for the passage of the claws 53A.
De manière préférentielle, les griffes 53A de la mâchoire et les rampes 40 de la tubulure en matériau inox sont recouvertes de Téflon ou traitées par immersion dans un bain d'étain, puis éventuellement recouvert d'un vernis, afin de favoriser le glissement lors de l'ouverture ou la fermeture du bouchon 5.Preferably, the claws 53A of the jaw and the ramps 40 of the stainless steel tubing are covered with Teflon or treated by immersing in a tin bath, then optionally covered with a varnish, to promote sliding during the opening or closing of the cap 5.
La mâchoire 53 comporte deux trous oblong 53B dans lesquels s'insèrent deux pions d'assemblage 52 de sorte que la rotation du couvercle 50 entraîne la rotation de la mâchoire 53, les trous oblongs 53B autorisant un léger débattement rotatif de la mâchoire 53 par rapport au couvercle 50, des ressorts de rappel 54 étant prévus pour amener la mâchoire 53 en butée contre une extrémité des trous oblongs 53B.The jaw 53 has two oblong holes 53B in which two assembly pins 52 are inserted so that the rotation of the cover 50 causes the jaw 53 to rotate, the oblong holes 53B allowing a slight rotational movement of the jaw 53 relative to to the cover 50, return springs 54 being provided to bring the jaw 53 into abutment against one end of the oblong holes 53B.
Comme on peut le voir sur la figure 3, le disque 51 comporte une ouverture centrale 51 B entourée d'un manchon périphérique dans lequel vient s'insérer un noyau central 55 en laiton, l'extrémité supérieure du noyau central 55 s'insérant dans une ouverture centrale 53C de la mâchoire 53. Le noyau 55 comporte un premier épaulement 55A venant en appui contre le bord de l'ouverture centrale 53C de la mâchoire et présente une rainure 55B recevant un anneau élastique 58 bloquant axialement la mâchoire 53 sur le noyau 55, le noyau 55 pouvant cependant tourner librement par rapport à la mâchoire 53.As can be seen in Figure 3, the disk 51 has a central opening 51 B surrounded by a peripheral sleeve in which is inserted a central core 55 of brass, the upper end of the central core 55 being inserted in a central opening 53C of the jaw 53. The core 55 has a first shoulder 55A bearing against the edge of the central opening 53C of the jaw and has a groove 55B receiving an elastic ring 58 axially locking the jaw 53 on the core 55, the core 55 being able to rotate freely relative to the jaw 53.
La partie inférieure du noyau 55 reçoit un joint annulaire 56 qui est engagé élastiquement dans une gorge délimitée dans sa partie supérieure par un second épaulement 55C, ce dernier présentant un diamètre extérieur correspondant sensiblement au diamètre extérieur du joint 56.The lower part of the core 55 receives an annular seal 56 which is engaged elastically in a groove delimited in its upper part by a second shoulder 55C, the latter having an outer diameter corresponding substantially to the outside diameter of the seal 56.
Un tel épaulement 55C permet de presser le joint 56 annulaire contre le bord de l'orifice de remplissage 3 lorsque la mâchoire 53 du bouchon est vissée sur la tubulure de remplissage 4, ainsi que cela est illustré sur la figure 5, la rampe 40 de la tubulure s'étendant hélicoïdalement de sorte que la rotation de la mâchoire 53 s'accompagne d'une translation axiale du noyau 55 vers l'orifice de remplissage 3. Lors de cette fermeture du bouchon 5, la libre rotation du noyau 55 par rapport à la mâchoire 53 présente l'avantage d'appliquer axialement le joint 56 en bordure de l'orifice 3 sans entraîner ce dernier en rotation, ce qui permet de limiter considérablement l'usure du joint 56 par friction.Such a shoulder 55C makes it possible to press the annular seal 56 against the edge of the filling orifice 3 when the jaw 53 of the stopper is screwed onto the filler neck 4, as is illustrated in Figure 5, the ramp 40 of the tubing extending helically so that the rotation of the jaw 53 is accompanied by an axial translation of the core 55 to the orifice 3. When closing the cap 5, the free rotation of the core 55 relative to the jaw 53 has the advantage of axially applying the seal 56 at the edge of the orifice 3 without causing the latter to rotate, this which makes it possible to considerably limit the wear of the seal 56 by friction.
Le joint 56 est avantageusement réalisé en silicone ou en matériau EPDM (Éthylène Propylène Diène Monomère) et présente une hauteur minimale deThe seal 56 is advantageously made of silicone or of EPDM material (Ethylene Propylene Diene Monomer) and has a minimum height of
4mm et préférentiellement de l'ordre de 10mm, de manière à pouvoir être comprimé, lorsque le bouchon 5 est vissé sur la tubulure de remplissage 4, au minimum de 10% de sa hauteur et au maximum de 30 %, en fonction des tolérances de fabrication. Une telle caractéristique permet d'assurer à la fois une bonne étanchéité et une durée de vie importante du joint 56 en lui permettant de conserver une bonne élasticité dans le temps.4mm and preferably of the order of 10mm, so as to be compressed, when the cap 5 is screwed on the filler pipe 4, at least 10% of its height and at most 30%, depending on the tolerances of manufacturing. Such a feature ensures both a good seal and a long life of the seal 56 by allowing it to maintain good elasticity over time.
De manière avantageuse, la tubulure de remplissage 4 est munie d'une ouverture 42, ou d'une échancrure latérale, permettant d'évacuer un éventuel trop plein d'eau présent dans la tubulure de remplissage. L'orifice de remplissage 3 présente avantageusement un diamètre compris entre 20mm et 40mm, et préférentiellement de l'ordre de 30mm, de manière à permettre un remplissage ou une vidange rapide de la cuve 2 sans toutefois avoir des efforts excessifs sur les rampes 40 de la tubulure de remplissage du fait de la pression exercée sur le bouchon 5. A titre d'exemple, un diamètre de 30mm de l'orifice 3 permet d'avoir un remplissage ou une vidange de 1 litre d'eau en 6 secondes.Advantageously, the filler neck 4 is provided with an opening 42, or a lateral notch, for evacuating any overflow of water present in the filler neck. The filling orifice 3 advantageously has a diameter of between 20 mm and 40 mm, and preferably of the order of 30 mm, so as to allow filling or rapid emptying of the tank 2 without, however, having excessive forces on the ramps 40 of the filler pipe due to the pressure exerted on the cap 5. For example, a diameter of 30mm of the orifice 3 allows a filling or a drain of 1 liter of water in 6 seconds.
Afin de faciliter la manipulation du bouchon 5, le couvercle 50 comporte une poignée 57 s'étendant radialement, la face latérale de la poignée 57 venant actionner un interrupteur de sécurité 7 interdisant l'activation des moyens de chauffe de la cuve 2 lorsque le bouchon 5 n'est pas parfaitement fermé. Cet interrupteur de sécurité 7, représenté en pointillé sur les figures 1A à 1C, est porté par le boîtier 10 et est disposé en fin de course de la trajectoire balayée par la poignée 57 lors de la fermeture du bouchon 5. Un voyant 70 est associé à cet interrupteur de sécurité 7 de manière à avertir l'utilisateur sur l'état de l'interrupteur de sécurité 7 et donc sur la fermeture correcte du bouchon 5.In order to facilitate the handling of the plug 5, the lid 50 comprises a handle 57 extending radially, the lateral face of the handle 57 coming to actuate a safety switch 7 preventing the activation of the heating means of the tank 2 when the plug 5 is not perfectly closed. This safety switch 7, shown in dashed lines in FIGS. 1A to 1C, is carried by the housing 10 and is arranged at the end of the course of the swept path. by the handle 57 when closing the cap 5. An indicator 70 is associated with this safety switch 7 so as to warn the user on the state of the safety switch 7 and thus on the correct closure of the plug 5 .
De manière avantageuse, la poignée 57 intègre un indicateur de pression formé par un levier 8 pivotant à l'intérieur du corps de la poignée 57 autour d'un axe 80, ce levier 8 comportant une extrémité arrondie 81 venant en regard d'une ouverture 57A réalisée dans la paroi inférieure de la poignée 57 et une surface indicatrice 82 se déplaçant en regard d'une fenêtre 57B réalisée dans la surface supérieure de la poignée. Ce levier 8 est destiné à coopérer avec un organe de sécurité 9 porté par la cuve 2, l'organe de sécurité comportant un doigt 90 traversant le boîtier 10 au niveau d'un orifice 10A se trouvant en regard de l'ouverture 57A de la poignée lorsque cette dernière se trouve dans la position fermée illustrée à la figure 1C.Advantageously, the handle 57 incorporates a pressure indicator formed by a lever 8 pivoting inside the body of the handle 57 about an axis 80, this lever 8 having a rounded end 81 coming opposite an opening 57A made in the bottom wall of the handle 57 and an indicator surface 82 moving opposite a window 57B made in the upper surface of the handle. This lever 8 is intended to cooperate with a safety member 9 carried by the tank 2, the safety member comprising a finger 90 passing through the housing 10 at an orifice 10A located opposite the opening 57A of the handle when the latter is in the closed position illustrated in Figure 1C.
Le fonctionnement de l'organe de sécurité 9 et son interaction avec le levier 8 indicateur de pression vont maintenant être décrits en relation avec les figures 6 et 7.The operation of the safety member 9 and its interaction with the pressure indicator lever 8 will now be described in relation to FIGS. 6 and 7.
La figure 6 illustre la position de l'organe de sécurité 9 lorsque la différence de pression entre la cuve 2 et la pression atmosphérique n'excède pas 0,02 bar.FIG. 6 illustrates the position of the safety member 9 when the pressure difference between the tank 2 and the atmospheric pressure does not exceed 0.02 bar.
Conformément à cette figure, l'organe de sécurité 9 se trouve alors en position basse dans laquelle l'extrémité du doigt 90 de l'organe de sécurité se trouve affleurant avec la surface supérieure du boîtier 10. Le levier 8 présent dans la poignée occupe alors une première position dans laquelle il est amené par gravité. Dans cette position, le levier 8 est en buté contre la paroi inférieure de la poignée 57, l'extrémité arrondie 81 du levier se trouvant alors à l'intérieur de l'orifice 57A de sorte qu'une première zone 82A de la surface indicatrice 82 se trouve en regard de la fenêtre 57B. De manière avantageuse, cette première partie 82A de la surface indicatrice 82 est de couleur verte pour indiquer à l'utilisateur qu'il peut ouvrir le bouchon 5. En effet, lorsque l'organe de sécuritéAccording to this figure, the safety member 9 is then in the low position in which the end of the finger 90 of the safety member is flush with the upper surface of the housing 10. The lever 8 present in the handle occupies then a first position in which it is brought by gravity. In this position, the lever 8 is abutted against the bottom wall of the handle 57, the rounded end 81 of the lever then being inside the orifice 57A so that a first zone 82A of the indicator surface 82 is next to window 57B. Advantageously, this first portion 82A of the indicator surface 82 is green to indicate to the user that it can open the cap 5. In fact, when the security organ
9 se trouve dans cette position, la poignée 57 n'est pas bloquée en rotation par le doigt 90 et peut donc être tournée sans difficulté par l'utilisateur.9 is in this position, the handle 57 is not locked in rotation by the finger 90 and can be rotated without difficulty by the user.
Lorsque la différence de pression entre la cuve 2 et la pression atmosphérique est supérieure à 0.02 bar, par exemple suite à i'activation des moyens de chauffe, le doigt 90 de l'organe de sécurité est déplacé vers le haut ainsi que cela est illustré à la figure 7. Dans cette position, le doigt 90 de l'organe de sécurité se trouve engagé dans l'orifice 57A de la poignée 57, empêchant tout mouvement de rotation du bouchon 5. L'insertion du doigt 90 au travers de l'orifice 57A est accompagnée du pivotement du levier 8 dans une position dans laquelle une deuxième partie 82B de la surface indicatrice 82 se trouve en regard de la fenêtre 57B, cette deuxième partie 82B étant avantageusement de couleur rouge de manière à alerter l'utilisateur sur l'impossibilité d'ouvrir le bouchon 5 du fait de la pression de vapeur excessive régnant dans la cuve 2.When the pressure difference between tank 2 and atmospheric pressure is greater than 0.02 bar, for example following the activation of the heating means, the finger 90 of the safety member is moved upwards as shown in Figure 7. In this position, the finger 90 of the safety member is engaged in the orifice 57A of the handle 57, preventing any rotational movement of the plug 5. The insertion of the finger 90 through the orifice 57A is accompanied by the pivoting of the lever 8 in a position in which a second portion 82B of the indicator surface 82 is facing the window 57B, this second portion 82B is preferably red in color so as to alert the user to the impossibility of opening the plug 5 due to the excessive vapor pressure prevailing in the tank 2.
L'utilisateur est alors obligé d'attendre que la pression dans la cuve 2 chute en deçà du seuil de 0.02 bar pour pouvoir ouvrir le bouchon. Cette chute de la pression s'effectue naturellement lorsque la température de la cuve 2 baisse et peut être accélérée par l'utilisateur en actionnant, par exemple, la gâchette pour l'envoi de vapeur équipant le fer à repasser.The user is then obliged to wait until the pressure in the tank 2 drops below the threshold of 0.02 bar to open the cap. This drop in pressure occurs naturally when the temperature of the tank 2 drops and can be accelerated by the user by actuating, for example, the trigger for sending steam equipping the iron.
En cas de tentative d'ouverture du bouchon 5 alors que le doigt 90 est engagé dans la poignée 57, le léger débattement rotatif existant dans la liaison entre la poignée 57 et la mâchoire 53, du fait de la présence des trous oblongs 53B, permet de ne pas laisser le doigt 90 de sécurité sous contrainte latérale, les ressorts de rappel 54 ayant tendance a ramener la poignée 57 dans une position correcte par rapport au doigt 90 de sécurité. Le risque que le doigt de sécurité 90 soit coincé en position haute par les efforts latéraux engendrés par la poignée 57 est ainsi éliminé.In case of an attempt to open the cap 5 while the finger 90 is engaged in the handle 57, the slight rotational movement existing in the connection between the handle 57 and the jaw 53, due to the presence of the oblong holes 53B, allows not to leave the safety finger 90 under lateral stress, the return springs 54 tending to bring the handle 57 in a correct position relative to the safety pin 90. The risk that the safety pin 90 is jammed in the upper position by the lateral forces generated by the handle 57 is thus eliminated.
Afin de faciliter l'ouverture du bouchon 5 et contrer une éventuelle dépression pouvant apparaître dans la cuve 2 lors du refroidissement de cette dernière, il est prévu, sur la surface du boîtier 10 balayée par la poignée 57, une rampe 10B disposée à l'extrémité de la course rotative d'ouverture du bouchon 5. Cette rampe 10B, visible sur la figure 4, présente une hauteur de l'ordre de 3mm qui assure le soulèvement et le pivotement de la poignée 57 et donc du joint 56 lors de la rotation du bouchon 5 pour son ouverture, créant une mise à l'air de la cuve 2.In order to facilitate the opening of the plug 5 and counter a possible depression that may appear in the tank 2 during the cooling thereof, there is provided, on the surface of the housing 10 swept by the handle 57, a ramp 10B disposed at the end of the rotary opening stroke of the cap 5. This ramp 10B, visible in Figure 4, has a height of about 3mm which ensures the lifting and pivoting of the handle 57 and therefore the seal 56 during the rotation of the cap 5 for its opening, creating a vent of the tank 2.
Un tel appareil présente l'avantage de procurer une très grande ergonomie d'utilisation en permettant l'ouverture rapide du bouchon pour le remplissage de la cuve tout en ayant une très grande sécurité d'utilisation.Such a device has the advantage of providing a very great ergonomics of use by allowing the quick opening of the cap for filling the tank while having a very high safety of use.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
Ainsi, dans l'exemple illustré, le noyau central est creux et comporte une cavité centrale fermée par une paroi assurant l'étanchéité du bouchon. Cependant, dans une variante de réalisation non illustrée, la cavité centrale pourra recevoir, de manière connue en soi, une soupape de sécurité soumise à la pression de la cuve au moyen d'un orifice réalisé dans la paroi. Cette soupape de sécurité pourra par exemple être tarée pour s'ouvrir au-delà de 6 bars de pression de manière à prévenir tout défaut de régulation des moyens de chauffe de la cuve. Thus, in the illustrated example, the central core is hollow and comprises a central cavity closed by a wall ensuring the sealing of the plug. However, in an alternative embodiment not shown, the central cavity may receive, in a manner known per se, a safety valve subjected to the pressure of the tank by means of an orifice made in the wall. This safety valve may for example be calibrated to open beyond 6 bars of pressure so as to prevent any regulation fault of the heating means of the tank.
