Description

La présente invention concerne le domaine technique des objets gonflables tel qu'un matelas gonflable et celui des sacs à remplir d'air et concerne en particulier un dispositif à remplir d'air tel qu'un dispositif de détente muni d'un moyen de fermeture rapide.The present invention relates to the technical field of inflatable objects such as an inflatable mattress and that of bags to be filled with air and relates in particular to a device to be filled with air such as a relaxation device provided with a closure means fast.

Etat de la techniqueState of the art

Il existe des objets gonflables ou sacs à remplir d'air que l'on remplit d'air très rapidement grâce à une large ouverture et qui sont munis d'un moyen de fermeture étanche. Pour éviter que l'air ne s'échappe après le remplissage de l'objet, le moyen de fermeture étanche doit pouvoir être mis en place rapidement.There are inflatable objects or bags to be filled with air which are filled with air very quickly thanks to a wide opening and which are provided with a means of sealing. To prevent the air from escaping after the object has been filled, the sealing means must be able to be put in place quickly.

Par exemple, il existe des sacs gonflables dont l'ouverture est munie de baguettes flexibles. Une fois l'ouverture refermée, les deux baguettes sont l'une contre l'autre et sont enroulées sur elles-mêmes et sur le col de l'ouverture du sac. Les deux baguettes sont ensuite recourbées de façon à ce que le col de l'ouverture du sac ait un profil courbe. Les deux baguettes maintenues serrées l'une contre l'autre par l'action élastique de leur courbure empêchent l'air de sortir du sac. Cette position courbe est maintenue grâce à deux dispositifs d'accouplement complémentaires situés respectivement à chaque extrémité des baguettes en coopérant ensemble par clipsage. Ce dispositif est décrit par exemple dans le document WO2018034561A1 .For example, there are air bags whose opening is provided with flexible rods. Once the opening is closed, the two rods are against each other and are rolled up on themselves and on the neck of the opening of the bag. The two rods are then bent over so that the neck of the bag opening has a curved profile. The two rods held tight against each other by the elastic action of their curvature prevent the air from coming out of the bag. This curved position is maintained thanks to two complementary coupling devices located respectively at each end of the rods by cooperating together by clipping. This device is described for example in the document WO2018034561A1 .

L'inconvénient d'un tel dispositif réside dans le fait que le moyen de fermeture impose que le col de l'ouverture du sac soit enroulé sur lui-même puis courbé pour garantir l'étanchéité. De sorte que le sac une fois gonflé ne peut pas se présenter par exemple sous la forme d'un matelas parfaitement plat.The disadvantage of such a device lies in the fact that the closure means require that the neck of the opening of the bag be rolled up on itself and then bent to guarantee sealing. So that the bag once inflated cannot appear for example in the form of a perfectly flat mattress.

C'est pourquoi, le but de l'invention est de réaliser un dispositif à remplir d'air muni d'une grande ouverture et d'un moyen de fermeture permettant la fermeture rapide du sac et qui évite de courber sur lui-même le col de l'ouverture du sac.This is why the object of the invention is to provide a device to be filled with air provided with a large opening and a closing means allowing the bag to be closed quickly and which avoids bending the bag on itself. neck of the bag opening.

L'objet de l'invention est donc un dispositif comprenant au moins une poche souple délimitant un volume intérieur, une ouverture d'entrée d'air par poche souple pour permettre à l'air de pénétrer dans le volume intérieur de la poche, un moyen de fermeture permettant de fermer de manière étanche l'entrée d'air, le moyen de fermeture comprenant deux baguettes flexibles situées à la périphérie de l'ouverture d'entrée d'air, les baguettes étant liées par leurs extrémités sont destinées à venir l'une contre l'autre.The object of the invention is therefore a device comprising at least one flexible pocket delimiting an interior volume, an air inlet opening per flexible pocket to allow air to penetrate into the interior volume of the pocket, a closure means making it possible to close the air inlet in a leaktight manner, the closure means comprising two flexible strips located at the periphery of the air inlet opening, the strips being linked by their ends are intended to come one against the other.

Selon la caractéristique principale, le dispositif comprend au moins une partie mobile rigide reliée de manière pivotante sur une des extrémités des baguettes de façon à ce que la partie mobile peut être positionnée autour des baguettes dans une position de fermeture dans laquelle les deux baguettes sont maintenues serrées l'une contre l'autre de façon à empêcher l'air de sortir du dispositif lorsque celui-ci est rempli d'air.According to the main characteristic, the device comprises at least one rigid movable part pivotally connected to one of the ends of the strips so that the movable part can be positioned around the strips in a closed position in which the two strips are held pressed against each other so as to prevent air from escaping from the device when it is filled with air.

Grâce à cette ouverture, l'air peut pénétrer dans la poche rapidement. Le dispositif de détente est également muni de moyens de fermeture de l'ouverture 13. Ces moyens comprennent deux baguettes flexibles 14 et 16 situées à la périphérie de l'ouverture 13. En position au repos, ces deux baguettes se superposent et sont maintenues serrées l'une contre l'autre à leurs deux extrémités par un moyen de serrage de type vis 15 et 17 ou par tout autre moyen. Les deux baguettes peuvent être écartées l'une de l'autre par une personne qui les saisit en leur centre dans une position d'ouverture de la poche 12 comme illustré sur les figures 1 et 3. Pendant cette manipulation, les baguettes flexibles 14 et 16 sont fléchies volontairement. Les dimensions des baguettes et en particulier leur épaisseur et le matériau qui les compose permettent cette déformation élastique. Les baguettes 14 et 16 sont de préférence en plastique.The trigger device comprises an opening 13 that is large enough in relation to the dimensions of the pocket. The opening 13 is located on one of the short sides of the expansion device and its width is substantially equal to the width of the expansion device. Thanks to this opening, air can enter the pocket quickly. The relaxation device is also provided with means for closing the opening 13. These means comprise two flexible rods 14 and 16 located at the periphery of the opening 13. In the rest position, these two rods overlap and are held tight one against the other at their two ends by a clamping means of the screw type 15 and 17 or by any other means. The two sticks can be separated from each other by a person who grasps them in their center in a position of opening of the pocket 12 as illustrated in the figure 1 And 3 . During this manipulation, the flexible rods 14 and 16 are bent voluntarily. The dimensions of the rods and in particular their thickness and the material of which they are made allow this elastic deformation. Rods 14 and 16 are preferably made of plastic.

Les moyens de fermeture comprennent également au moins une partie mobile 25 selon les figures 1 et 2 et de préférence deux parties mobiles 24 et 26 selon les figures 3 et 4 en plastique rigide et de section transversale creuse de préférence sensiblement en forme de U de façon à former une mâchoire sur toute leur longueur. Le mode de réalisation préféré du dispositif selon l'invention avec deux parties mobiles 24 et 26 est illustré sur les figures 3 et 4. Les parties mobiles 24 et 26 sont reliées aux baguettes 14 et 16 de manière pivotante autour d'un axe situé à chacune des extrémités des baguettes 14 et 16. L'axe de rotation peut être commun avec l'axe des vis 15 et 17. Les parties mobiles 24, 25 et 26 sont dimensionnées pour venir enserrer dans leur mâchoire les deux baguettes de façon à les maintenir serrer l'une contre l'autre sur toute leur longueur. Selon le mode de réalisation préféré de l'invention, les baguettes 14 et 16 et les parties mobiles 24, 25 et 26 sont droites.The closing means also comprise at least one movable part 25 according to the figures 1 and 2 and preferably two moving parts 24 and 26 according to the figures 3 and 4 rigid plastic and hollow cross section preferably substantially U-shaped so as to form a jaw along their entire length. The preferred embodiment of the device according to the invention with two parts mobiles 24 and 26 is illustrated on the figures 3 and 4 . The movable parts 24 and 26 are connected to the rods 14 and 16 in a pivoting manner around an axis located at each of the ends of the rods 14 and 16. The axis of rotation can be common with the axis of the screws 15 and 17. The moving parts 24, 25 and 26 are sized to grip the two rods in their jaws so as to keep them tight against each other over their entire length. According to the preferred embodiment of the invention, the rods 14 and 16 and the moving parts 24, 25 and 26 are straight.

Dans la position où les parties mobiles 24 et 26 sont placées autour des baguettes 14 et 16, appelée position de fermeture dans la suite de la description, l'air ne peut pas passer entre les baguettes maintenues serrées l'une contre l'autre, le dispositif de détente est complètement étanche et l'air emprisonné dans la poche ne peut pas ressortir. Le matelas 10 illustré sur les figures 3 et 4 est prêt à être utilisé. Au moins une partie mobile présente un orifice 29 qui permet d'accrocher le dispositif pour le transformer en une bouée de flottaison par exemple.In the position where the movable parts 24 and 26 are placed around the rods 14 and 16, called the closed position in the remainder of the description, the air cannot pass between the rods held tight against each other, the trigger device is completely sealed and the air trapped in the pocket cannot escape. The mattress 10 shown in the figures 3 and 4 is ready to use. At least one mobile part has an orifice 29 which makes it possible to attach the device to transform it into a flotation buoy for example.

Selon une autre utilisation du dispositif selon l'invention, la poche comprend une seconde ouverture 33 qui fait office de sortie d'air dont les détails sont décrits en référence à la figure 10.According to another use of the device according to the invention, the pocket comprises a second opening 33 which acts as an air outlet, the details of which are described with reference to the figure 10 .

Comme on peut le voir sur la figure 5, les deux baguettes 14 et 16 ont une section sensiblement rectangulaire mais présentent des arêtes arrondies afin de limiter les risques de percer la poche.As can be seen on the figure 5 , the two rods 14 and 16 have a substantially rectangular section but have rounded edges in order to limit the risk of piercing the pocket.

La poche souple 12 présente deux parois de part et d'autre de l'ouverture, une paroi supérieure 121 et une paroi inférieure 122. La paroi inférieure peut être recouverte d'un matériau protecteur tel qu'une couche de mousse pour rendre le dispositif résistant en cas d'utilisation en camping. Les bords de chaque paroi, situés à la périphérie de l'ouverture 13, sont reliés chacun à respectivement une baguette 14 et 16. Selon un mode de réalisation préféré de l'invention, le bord de la paroi 121 à la périphérie de l'ouverture 13 forme un fourreau dans lequel est logé la baguette 14. De même, le bord de la paroi 122 à la périphérie de l'ouverture 13 forme un fourreau dans lequel est logé la seconde baguette 16. Le bord de la paroi 121 est donc enrouler autour de la baguette 14 et fixé de préférence contre la face externe de la paroi 121. La fixation illustrée par une zone hachurée 325 est réalisée par collage, scellage, soudage ou par couture. De préférence, selon ce mode de réalisation, les parois de la poche ne sont pas collées sur les baguettes 14 et 16.The flexible bag 12 has two walls on either side of the opening, an upper wall 121 and a lower wall 122. The lower wall can be covered with a protective material such as a layer of foam to make the device resistant when used in camping. The edges of each wall, located at the periphery of the opening 13, are each connected to respectively a strip 14 and 16. According to a preferred embodiment of the invention, the edge of the wall 121 at the periphery of the opening 13 forms a sheath in which the strip 14 is housed. likewise, the edge of the wall 122 at the periphery of the opening 13 forms a sheath in which the second rod 16 is housed. The edge of the wall 121 is therefore wrapped around the rod 14 and fixed preferably against the external face of the wall 121. The fixing illustrated by a hatched area 325 is carried out by gluing, sealing, welding or by sewing. Preferably, according to this embodiment, the walls of the pocket are not glued to the rods 14 and 16.

Selon un autre mode de réalisation de l'invention, non représenté sur les figures, le bord de la paroi 121 à la périphérie de l'ouverture 13 est collé directement sur la baguette 14. De même, le bord de la paroi 122 à la périphérie de l'ouverture 13 est collé ou soudé directement sur la seconde baguette 16.According to another embodiment of the invention, not shown in the figures, the edge of the wall 121 at the periphery of the opening 13 is glued directly to the strip 14. Similarly, the edge of the wall 122 at the periphery of the opening 13 is glued or welded directly to the second strip 16.

Selon la vue de dessus de la figure 6, les baguettes ont une longueur 160 dimensionnée de façon à être légèrement supérieure ou égale à la dimension 100 de la largeur de l'ouverture 13) augmentée de la largeur des zones de fixation 326 située en périphérie, augmentée de la largeur 240 de chaque partie mobile en présence. Dans tous les cas, la longueur 160 des baguettes est dimensionnée pour pouvoir replier les parties mobiles le long du dispositif de détente lorsqu'elles sont dans leur position d'ouverture, ce qui est plus pratique pour le plier et pour la phase de remplissage d'air. Les baguettes 14 et 16 ont une largeur 140 comprise entre 1 cm et 4 cm et une épaisseur comprise entre 1 mm et 4 mm. Les zones de fixation 325 des parois 121 et 122 repliées sur elles-mêmes, situées le long des fourreaux dans lesquels sont logés les baguettes 14 et 16 ou situées directement sur les baguettes en absence de fourreaux, se prolongent sur les bords du matelas par une zone de fixation périphérique des parois 121 et 122 en contact l'une sur l'autre sur toute la périphérie. Sur la figure 6, seule une partie de cette zone de fixation 326 est représentée.According to the top view of the figure 6 , the rods have a length 160 dimensioned so as to be slightly greater than or equal to the dimension 100 of the width of the opening 13) increased by the width of the fixing zones 326 located on the periphery, increased by the width 240 of each part mobile in presence. In all cases, the length 160 of the rods is sized to be able to fold the movable parts along the trigger device when they are in their open position, which is more practical for folding it and for the filling phase of 'air. The rods 14 and 16 have a width 140 of between 1 cm and 4 cm and a thickness of between 1 mm and 4 mm. The fixing zones 325 of the walls 121 and 122 folded back on themselves, located along the sheaths in which the rods 14 and 16 are housed or located directly on the rods in the absence of sheaths, extend over the edges of the mattress by a peripheral fixing zone of the walls 121 and 122 in contact with each other over the entire periphery. On the figure 6 , only part of this attachment zone 326 is shown.

Selon la figure 7 qui représente une vue de dessus de l'ouverture 13 et du moyen de fermeture, les deux parties mobiles 24 et 26 ont été rabattues sur les baguettes donc dans leur position de fermeture, en pivotant autour de leur axe de rotation respectif 15 et 17 reliées aux extrémités des baguettes. La longueur des bords des parties mobiles est dimensionnée pour que lorsque les deux parties mobiles 25 et 26 sont en position de fermeture, les deux extrémités libres des parties mobiles se rejoignent et entrent en contact afin de fermer hermétiquement l'ouverture 13. On désigne par bord d'attaque le bord des parties mobiles par lequel la baguette est insérée dans les parties mobiles et bord de fuite le bord des parties mobiles dirigé vers l'extérieur. Si pour chaque partie mobile, la longueur du bord d'attaque est égale à la longueur du bord de fuite, les faces planes des extrémités libres des parties mobiles, en contact l'une de l'autre, sont perpendiculaires au bord de l'ouverture 13 de sorte que les parties mobiles 24 et 26 peuvent être mises en place dans leur position de fermeture dans un ordre indifférent.According to figure 7 which represents a top view of the opening 13 and of the closure means, the two movable parts 24 and 26 have been folded down on the rods, therefore in their closed position, by pivoting around their respective axis of rotation 15 and 17 connected at the ends of the rods. The length of the edges of the moving parts is dimensioned so that when the two moving parts 25 and 26 are in the closed position, the two free ends of the moving parts come together and come into contact in order to hermetically close the opening 13. leading edge the edge of the moving parts through which the rod is inserted into the moving parts and trailing edge the edge of the moving parts directed outwards. If for each moving part, the length of the leading edge is equal to the length of the trailing edge, the flat faces of the free ends of the moving parts, in contact with each other, are perpendicular to the edge of the opening 13 so that the movable parts 24 and 26 can be put in place in their closed position in any order.

Selon le mode de réalisation préféré de l'invention à deux parties mobiles, chaque partie mobile 24 et 26 a un bord d'attaque et un bord de fuite de longueur différente. La différence de longueur entre le bord d'attaque 241 et le bord de fuite 242 de la partie mobile 24 est égale à la différence de longueur entre le bord d'attaque 261 et le bord de fuite 262 de la partie mobile 26. De cette façon, les bords d'attaque et de fuite de chaque partie mobile sont reliés, du côté de l'extrémité libre de la partie mobile, par une face plane en biseau. Dans l'exemple représenté sur la figure 7, la face en biseau de l'extrémité libre de la partie mobile 24 est dirigée vers l'extérieur du dispositif tandis que la face en biseau de l'extrémité libre de la partie mobile 26 est dirigée vers l'intérieur du dispositif. Cette configuration impose que la partie mobile 24 soit mise en position de fermeture avant la partie mobile 26. Les angles des deux faces en biseau sont complémentaires afin que les faces coïncident parfaitement lorsque les parties mobiles sont en position de fermeture. Cette forme en biseau et cette complémentarité de l'extrémité libre des parties mobiles présentent l'avantage d'opposer une résistance à la pression de l'air contenu dans la poche du matelas. En effet, lorsque la pression de l'air pousse sur les parois 121 et 122 du matelas, la pression est également dirigée vers l'ouverture 13 et vers les baguettes et les parties mobiles 24 et 26 or l'ouverture de la partie mobile 24 est bloquée par la partie 26 car sa face d'extrémité en biseau appuie contre celle de la partie mobile 26. Ainsi, le moyen de fermeture de l'ouverture du dispositif est auto-bloquant.According to the preferred embodiment of the invention with two moving parts, each moving part 24 and 26 has a leading edge and a trailing edge of different length. The difference in length between the leading edge 241 and the trailing edge 242 of the mobile part 24 is equal to the difference in length between the leading edge 261 and the trailing edge 262 of the mobile part 26. way, the leading and trailing edges of each movable part are connected, on the side of the free end of the movable part, by a beveled planar face. In the example shown in the figure 7 , the bevelled face of the free end of the movable part 24 is directed towards the outside of the device while the bevelled face of the free end of the movable part 26 is directed towards the inside of the device. This configuration requires that the movable part 24 be placed in the closed position before the movable part 26. The angles of the two beveled faces are complementary so that the faces coincide perfectly when the movable parts are in the closed position. This beveled shape and this complementarity of the free end of the moving parts have the advantage of opposing resistance to the pressure of the air contained in the pocket of the mattress. Indeed, when the air pressure pushes on the walls 121 and 122 of the mattress, the pressure is also directed towards the opening 13 and towards the rods and the moving parts 24 and 26 or the opening of the moving part 24 is blocked by part 26 because its bevelled end face presses against that of the movable part 26. Thus, the means for closing the opening of the device is self-locking.

La figure 8 représente une coupe de la partie mobile 24, 25 ou 26 et une coupe des baguettes 14 et 16. Le mode de réalisation représenté sur les figures 8 et 9 correspond au mode où les parois 121 et 122 forment chacune un fourreau pour y loger les baguettes. La section transversale creuse de la partie mobile 24, 25 ou 26 définit une cavité 210 de préférence sensiblement en forme de U et adaptée pour recevoir les deux baguettes dans leur fourreau. Les partie mobiles 24, 25 et 26 comprennent deux jambes 201 et 202 reliées à un élément de connexion 203 qui est la base du U. L'épaisseur de l'élément de connexion 203 est supérieure à l'épaisseur des jambes 201 et 202. L'élément de connexion 203 permet ainsi de renforcer la partie mobile et d'augmenter la résistance à l'écartement des deux jambes.There figure 8 represents a section of the mobile part 24, 25 or 26 and a section of the rods 14 and 16. The embodiment represented on the figures 8 and 9 corresponds to the mode where the walls 121 and 122 each form a sleeve to accommodate the rods. The hollow cross-section of the movable part 24, 25 or 26 defines a cavity 210 which is preferably substantially U-shaped and adapted to receive the two rods in their sheath. The mobile parts 24, 25 and 26 comprise two legs 201 and 202 connected to a connection element 203 which is the base of the U. The thickness of the connection element 203 is greater than the thickness of the legs 201 and 202. The connection element 203 thus makes it possible to reinforce the mobile part and to increase the resistance to the separation of the two legs.

La largeur intérieure entre les deux jambes au niveau de la base 203 est supérieure à la largeur intérieure libre des deux jambes. On désigne par largeur intérieure libre la largeur des deux jambes au niveau du bord d'attaque des parties mobiles. La largeur intérieure libre doit être comprise entre la valeur de l'épaisseur totale comprenant les deux épaisseurs de baguettes, les épaisseurs des parois 121 et 122 (une ou deux épaisseurs selon le mode de réalisation) et cette valeur diminuée de 0,5 mm (millimètre).The interior width between the two legs at the level of the base 203 is greater than the free interior width of the two legs. The free internal width denotes the width of the two legs at the level of the leading edge of the moving parts. The free internal width must be between the value of the total thickness including the two thicknesses of strips, the thicknesses of the walls 121 and 122 (one or two thicknesses depending on the embodiment) and this value reduced by 0.5 mm ( millimeter).

Aux extrémités où les parties mobiles sont reliées aux baguettes par leur axe de rotation, les baguettes sont engagées entre les jambes 201 et 202 des parties mobiles. De ce fait, l'utilisateur n'a aucune difficulté à rabattre les parties mobiles sur les baguettes, car les baguettes s'engagent facilement et automatiquement entre les jambes 201 et 202 des parties mobiles au fur et à mesure du pivotement. Lorsque les parties mobiles sont dans leur position de fermeture, les baguettes sont insérées entre les jambes 201 et 202 des parties mobiles jusqu'au fond de la cavité 210, comme illustré sur la figure 9 qui est une vue en coupe selon A-A de la figure 7. Les baguettes sont contraintes par les jambes 201 et 202 des parties mobiles de par les dimensions des pièces. Les jambes 201 et 202 des parties mobiles exercent une pression de compression sur les baguettes 14 et 16 qui les serre l'une contre l'autre et empêche la fuite de l'air contenu dans la poche 12.At the ends where the moving parts are connected to the rods by their axis of rotation, the rods are engaged between the legs 201 and 202 of the moving parts. As a result, the user has no difficulty in folding the moving parts over the rods, since the rods engage easily and automatically between the legs 201 and 202 of the moving parts as the pivoting progresses. When the movable parts are in their closed position, the rods are inserted between the legs 201 and 202 of the movable parts as far as the bottom of the cavity 210, as illustrated in the figure 9 which is a sectional view according to AA of the figure 7 . The rods are constrained by the legs 201 and 202 of the moving parts due to the dimensions of the parts. The legs 201 and 202 of the moving parts exert a compressive pressure on the rods 14 and 16 which presses them against each other and prevents the escape of the air contained in the pocket 12.

Dans le mode de réalisation où les parties des parois 121 et 122 forment des fourreaux et ne sont pas collées sur les baguettes 14 et 16, les parois autour des baguettes ont tendance à s'écraser et s'étaler contre le fond de la cavité 210 de sorte qu'elles présentent l'avantage de favoriser l'étanchéité de la poche. Cet avantage est dû au fait que.In the embodiment where the parts of the walls 121 and 122 form sheaths and are not glued to the strips 14 and 16, the walls around the strips tend to crush and spread out against the bottom of the cavity 210 so that they have the advantage of promoting sealing of the pocket. This advantage is due to the fact that.

Lorsque les parties mobiles sont dans leur position de fermeture, la largeur des jambes 201 et 202 des parties mobiles dépassent des baguettes de préférence d'une distance 260 au moins égale à 2mm. Ainsi, à leur extrémité libre, les jambes 201 et 202 des parties mobiles peuvent se resserrer sur les baguettes de façon à fournir un renforcement de la pression de compression des jambes sur les baguettes.
Le dispositif selon l'invention comprend une seconde ouverture 33 qui sert de sortie d'air comme on peut le voir sur les figures 1 à 4 et 10. La figure 10 montre comment le dispositif de détente selon l'invention peut servir de sac pompe pour gonfler un dispositif gonflable 36 tel qu'une bouée. Pour cela, l'utilisateur raccorde le dispositif de détente au dispositif gonflable en raccordant une conduite 34 de la seconde ouverture 33 à l'ouverture d'entrée d'air 35 du dispositif gonflable. La seconde ouverture 33 comporte un bouchon et une valve anti-retour. L'utilisateur enroule ensuite le dispositif de détente sur lui-même ou presse le dispositif de façon à chasser l'air vers la sortie d'air 33 et à gonfler le dispositif gonflable 36. La seconde ouverture 33 peut également servir pour ajuster le gonflage du dispositif selon l'invention. En effet, quand la première ouverture est fermée, l'utilisateur peut encore faire entrer de l'air dans le dispositif en retirant le bouchon de la seconde ouverture et en soufflant soit à la bouche soit avec un gonfleur traditionnel, la valve anti-retour évitant que le dispositif ne se dégonfle lorsque le bouchon est retiré.When the moving parts are in their closed position, the width of the legs 201 and 202 of the moving parts protrude from the rods preferably by a distance 260 at least equal to 2mm. Thus, at their free end, the legs 201 and 202 of the movable parts can be tightened on the rods so as to provide reinforcement of the compression pressure of the legs on the rods.
The device according to the invention comprises a second opening 33 which serves as an air outlet as can be seen in the figures 1 to 4 And 10 . There figure 10 shows how the expansion device according to the invention can be used as a pump bag to inflate an inflatable device 36 such as a buoy. For this, the user connects the relaxation device to the inflatable device by connecting a pipe 34 from the second opening 33 to the air inlet opening 35 of the inflatable device. The second opening 33 comprises a stopper and a non-return valve. The user then wraps the relaxation device on himself or presses the device so as to expel the air towards the air outlet 33 and to inflate the inflatable device 36. The second opening 33 can also be used to adjust the inflation of the device according to the invention. Indeed, when the first opening is closed, the user can still introduce air into the device by removing the cap from the second opening and blowing either with the mouth or with a traditional inflator, the non-return valve preventing the device from deflating when the cap is removed.

Le dispositif selon l'invention peut également comprendre un moyen de sécurité qui s'ajoute au moyen de fermeture pour immobiliser les parties mobiles lorsqu'elles sont en position de fermeture.The device according to the invention can also comprise a safety means which is added to the closing means to immobilize the moving parts when they are in the closed position.

Un premier moyen de sécurité consiste en un moyen d'accrochage de type bandes auto-agrippantes crochet et velours (de type bandes Velcros) est illustré sur les figures 11a et 11b.A first security means consists of a means of attachment of the hook and velvet self-gripping strip type (of the Velcro strip type) is illustrated on the figures 11a and 11b .

Ce moyen comprend une languette 123 reliée à la paroi inférieure 122 muni d'une première bande 32 auto-agrippante de type crochet et une seconde bande auto-agrippante 31 de type velours fixée à la paroi supérieure 121 du dispositif. Les deux bandes étant adaptées à s'agripper l'une à l'autre lorsque la languette 123 entoure les parties mobiles lorsque celles-ci sont en position de fermeture. La languette 123 et les bandes auto-agrippantes 31 et 32 sont situées de préférence de façon à être à proximité des extrémités libres des parties mobiles 24 et 26. Lorsque les deux bandes sont en contact l'une de l'autre, comme illustrées sur la figure 10b, les deux parties mobiles sont immobilisées.This means comprises a tongue 123 connected to the lower wall 122 provided with a first self-gripping strip 32 of the hook type and a second self-gripping strip 31 of velvet type fixed to the upper wall 121 of the device. The two strips being adapted to cling to each other when the tongue 123 surrounds the movable parts when the latter are in the closed position. The tongue 123 and the hook-and-loop strips 31 and 32 are preferably located so as to be close to the free ends of the movable parts 24 and 26. When the two strips are in contact with each other, as illustrated in Figure 10b, the two moving parts are immobilized.

Un second moyen de sécurité consiste en un verrou à tige représenté en position ouvert sur la figure 12a et en position fermée sur la figure 12b. Le verrou comprend une première partie 41 fixée sur la partie mobile 24 et une seconde partie 43 fixée sur la seconde partie mobile 26, les deux parties fixes 41 et 43 étant situées à proximité des extrémités libres des parties mobiles. Le verrou à tige comprend également une tige 44 qui fait office de pêne, maintenue coulissante dans la partie fixe 43 de sorte qu'elle puisse, de préférence, coulisser sans se détacher de la partie fixe et donc du dispositif. Un utilisateur peut pousser la tige de façon à l'engager dans la seconde partie fixe 41 et à immobiliser les deux parties mobiles. Les deux parties fixes 41, 43 et la tige du verrou peuvent être également équipés d'encoches et de tétons, à la manière d'un verrou à picolet, pour maintenir la tige en place, soit dans la position du verrou ouvert soit dans la position du verrou fermé.A second security means consists of a rod lock shown in the open position on the figure 12a and in the closed position on the figure 12b . The lock comprises a first part 41 fixed to the mobile part 24 and a second part 43 fixed to the second mobile part 26, the two fixed parts 41 and 43 being located close to the free ends of the mobile parts. The rod lock also comprises a rod 44 which acts as a bolt, held sliding in the fixed part 43 so that it can preferably slide without detaching from the fixed part and therefore from the device. A user can push the rod so as to engage it in the second fixed part 41 and to immobilize the two moving parts. The two fixed parts 41, 43 and the rod of the lock can also be equipped with notches and studs, like a pin lock, to hold the rod in place, either in the position of the open lock or in the closed latch position.

Un troisième moyen de sécurité illustré sur les figures 13a et 13b consiste en un axe percé 53 et une bague ou tige de fixation 54, l'axe percé étant adapté pour être inséré dans un orifice 51 traversant la partie mobile 26 et les baguettes qu'elle enserre. Dans le cas d'un dispositif à deux parties mobiles, l'orifice est situé du côté de la partie mobile dont le bord d'attaque est le plus court. Dans le cas d'un dispositif à une partie mobile unique, l'orifice est situé de préférence du côté de l'extrémité libre de la partie mobile. L'immobilisation des parties mobiles est obtenue lorsque la tige est insérée dans l'orifice et que la bague ou tige de fixation est insérée dans le trou de la tige percée. La seconde partie mobile 24 peut également être équipée de ce moyen de sécurité.A third means of security illustrated on the figures 13a and 13b consists of a pierced pin 53 and a fixing ring or rod 54, the pierced pin being adapted to be inserted into an orifice 51 passing through the movable part 26 and the rods that it encloses. In the case of a device with two moving parts, the orifice is located on the side of the moving part whose leading edge is the shortest. In the case of a device with a single moving part, the orifice is located preferably on the side of the free end of the mobile part. The immobilization of the moving parts is obtained when the rod is inserted into the orifice and the fixing ring or rod is inserted into the hole of the pierced rod. The second mobile part 24 can also be equipped with this safety means.

Un quatrième moyen de sécurité illustré sur les figures 14a et 14b consiste en une pince coulissante 61, 63 située à l'extrémité libre des parties mobiles. Chaque pince coulisse entre deux positions, une première position où elle exerce aucun effort sur les jambes de la partie mobile et une seconde position où elle exerce un effort sur les jambes de la partie mobile qui tend à les resserrer l'une vers l'autre et empêcher leur écartement. Lorsque les parties mobiles sont dans leur position d'ouverture ou en train d'être manipulées pour passer d'une position à l'autre, la pince est dans sa première position comme illustrée sur la figure 14a. Lorsque les parties mobiles sont dans la position de fermeture, les pinces sont déplacées dans leur seconde position de façon à immobiliser les parties mobiles comme illustré sur la figure 14b. Les pinces 61 et 62 sont moulées dans la masse avec les parties mobiles de façon à ce qu'elles soient liées à elles.A fourth means of security illustrated on the figures 14a and 14b consists of a sliding clamp 61, 63 located at the free end of the moving parts. Each clamp slides between two positions, a first position where it exerts no force on the legs of the mobile part and a second position where it exerts a force on the legs of the mobile part which tends to tighten them towards each other and prevent their separation. When the moving parts are in their open position or being manipulated to pass from one position to another, the gripper is in its first position as illustrated in the picture 14a .
