Description

Dispositif de gonflage  Inflation device
La présente invention concerne le domaine des loisirs nautiques et a plus particulièrement pour objets un dispositif de gonflage pouvant être utilisé pour le gonflage d'une embarcation gonflable comprenant deux boudins latéraux et un fond, comportant chacun une chambre à air indépendante, ainsi qu'une embarcation gonflable équipée d'un tel dispositif de gonflage. The present invention relates to the field of water recreation and more particularly to objects an inflation device that can be used for inflating an inflatable boat comprising two lateral struts and a bottom, each having an independent air chamber, and a inflatable boat equipped with such an inflation device.
Une embarcation gonflable comporte généralement deux boudins latéraux indépendants comportant chacun une valve de même modèle destinée au gonflage et au dégonflage du boudin correspondant ainsi qu'une valve, souvent d'un autre modèle destiné au gonflage et au dégonflage du fond de l'embarcation gonflable.  An inflatable boat generally comprises two independent lateral struts each having a valve of the same model intended for inflating and deflating the corresponding strand and a valve, often of another model for inflating and deflating the bottom of the inflatable boat. .
Cependant, le gonflage d'une telle embarcation gonflable présente l'inconvénient d'entraîner une dissymétrie entre les deux boudins si ceux-ci sont gonflés alternativement avec de trop grand écart de pression.  However, the inflation of such an inflatable boat has the disadvantage of causing an asymmetry between the two flanges if they are inflated alternately with too large pressure difference.
Ces dissymétries sont essentiellement dues à la déformation de la paroi interne séparant les chambres à air des deux boudins qui va avoir tendance à se bomber vers la chambre à air de plus faible pression.  These dissymmetries are mainly due to the deformation of the inner wall separating the air chambers of the two flanges which will tend to bulge towards the air chamber of lower pressure.
Cela survient fréquemment lorsqu'u n des deux boud ins est entièrement gonflé avant de gonfler l'autre.  This occurs frequently when one of the two buds is fully inflated before inflating the other.
Pour prévenir à cet inconvénient, l'utilisateur doit, au cours de la phase de gonflage, connecter et déconnecter plusieurs fois sa pompe alternativement sur l'une et l'autre des valves des deux boudins latéraux.  To prevent this disadvantage, the user must, during the inflation phase, connect and disconnect several times his pump alternately on one and the other of the valves of the two lateral flanges.
Cependant, ce gonflage indépendant des deux boudins latéraux est laborieux et laisse subsister une légère dissymétrie entre les deux chambres à air des deux boudins, l'une étant toujours irrémédiablement plus gonflée que l'autre.  However, this independent inflation of the two lateral flanges is laborious and leaves a slight dissymmetry between the two air chambers of the two flanges, one is always irremediably more inflated than the other.
Les normes en vigueur dans domaine des embarcations gonflables d isposent qu'en cas de crevaison de l'un des deux boudins latéraux, l'embarcation gonflable doit restée gonflée à au moins 50% de son volume gonflable, ce q u i i n terd it d es co n cept io n s à deux boudins latéraux communiquant au travers une seule chambre à air, ce qui résoudrait pourtant le problème de la dissymétrie.  The standards applicable in the field of inflatable boats are that in the event of a puncture on one of the two lateral struts, the inflatable boat must have remained inflated to at least 50% of its inflatable volume, which means that Two ceilings with two lateral flanges communicating through a single air chamber, which would solve the problem of dissymmetry.
La présente invention a pour but de résoudre tout ou partie des inconvénients mentionnés ci-dessus. A cet effet la présente invention a pour objet un dispositif de gonflage pouvant être utilisé pour le gonflage d'une embarcation gonflable comprenant deux boudins latéraux et un fond comportant chacun une chambre à air indépendante, ledit dispositif étant caractérisé en ce qu'il comporte un corps étanche comprenant une enceinte présentant au moins trois ouvertures de communication, chacune des ouvertures étant reliées à une autre ouverture par un passage permettant la circulation d'un flux d'air, et notamment une première ouverture destinée à être reliée à un premier moyen d'acheminement d'air destiné à alimenter en air la chambre à air du premier boudin latéral de l'embarcation gonflable, une deuxième ouverture destinée à être reliée à un deuxième moyen d'acheminement d'air destiné à alimenter en air la chambre à air du deuxième boudin latéral de l'embarcation gonflable, une troisième ouverture destinée à être raccordée à une pompe de gonflage, et une embase réunissant les deux moyens d'acheminement en air des deux boudins, une base amovible pouvant être reliée d'une part à l'embase et comportant deux conduits d'air disposés dans le prolongement des deux moyens d'acheminement en air des deux boudins, et pouvant être reliée d'autre part au corps étanche du dispositif de gonflage.

Cette disposition permet un équilibre de la pression des deux boudins au cours du gonflage et de séparer les chambres à air des deux boudins une fois leur gonflage effectué.  This arrangement allows a balance of the pressure of the two flanges during inflation and to separate the air chambers of the two flanges once inflated.
Selon un mode de réalisation, le dispositif de gonflage comporte des moyens de positionnement des moyens d'obstruction dans une position intermédiaire se trouvant entre la position d'ouverture et la position de fermeture.  According to one embodiment, the inflation device comprises means for positioning the obstruction means in an intermediate position between the open position and the closed position.
Cette disposition a pour effet de permettre un contrôle du flux d'air transitant entre les deux boudins au travers le dispositif de gonflage, par exemple lors d'un rééquilibre rendu nécessaire suite à la perte de pression de l'un des boudins. This arrangement has the effect of allowing a control of the flow of air passing between the two flanges through the inflation device, by example during a rebalance made necessary following the loss of pressure of one of the tubes.
Selon un mode de réalisation, les moyens de positionnement comportent des moyens de rappel des moyens d'obstruction vers sa position d'ouverture.  According to one embodiment, the positioning means comprise means for returning the obstruction means to its open position.
Cette disposition permet un positionnement par défaut dans lequel la pression des chambres à air s'équilibre.  This arrangement allows a default positioning in which the pressure of the inner tubes equilibrates.
Selon un mode de réal isation, les moyens de positionnement comportent un organe poussoir et un organe de manipulation réalisant un dispositif de transformation du mouvement du type vis-écrou transformant un mouvement relatif en rotation de l'organe de manipulation en mouvement relatif en translation de l'organe poussoir pour amener les moyens d'obstruction vers leur position de fermeture.  According to one embodiment, the positioning means comprise a pusher member and a manipulation member producing a screw-nut-type movement transformation device transforming a relative rotational movement of the manipulation member in relative movement in translation of the pusher member for bringing the obstruction means to their closed position.
Cette disposition permet à l'utilisateur de passer d'une position à l'autre par un simple mouvement de rotation.  This arrangement allows the user to move from one position to another by a simple rotational movement.
Selon un mode de réalisation, le dispositif comporte des moyens d'attache des moyens de positionnement à l'enceinte du dispositif de gonflage.  According to one embodiment, the device comprises means for attaching the positioning means to the enclosure of the inflation device.
Cette disposition permet de maintenir en place les moyens de positionnement lorsque la pression à l'intérieur de la chambre de chacun des boudins latéraux devient importante.  This arrangement makes it possible to keep in place the positioning means when the pressure inside the chamber of each of the lateral flanges becomes large.
S e l o n u n m o d e d e r é a l i s a t i o n , les moyens d'obstruction comprennent un dispositif anti-retour empêchant le passage de l'air d a n s l e se n s a l l a nt d e la première ouverture ou de la deuxième ouverture vers la troisième ouverture.  The obstruction means comprise a non-return device preventing the passage of air between the first opening and the second opening to the third opening.
Cette disposition permet de maintenir l'air insufflé par la pompe au travers le dispositif de gonflage à l'intérieur des chambres à air des boudins latéraux.  This arrangement keeps the air blown by the pump through the inflation device inside the air chambers of the side flanges.
Selon un mode de réalisation, l'enceinte présente une quatrième ouverture destinée à être reliée à un troisième moyen d'acheminement d'air destiné à al imenter en air la chambre à air du fond de l'embarcation gonflable, chacune des ouvertures étant reliées à une autre ouverture par un passage permettant la circulation d'un flux d'air.  According to one embodiment, the enclosure has a fourth opening intended to be connected to a third air conveying means for supplying air to the air chamber of the bottom of the inflatable boat, each of the openings being connected to to another opening by a passage allowing the circulation of a flow of air.
Cette disposition permet de gonfler simultanément les boudins latéraux et le fond de l'embarcation.  This arrangement makes it possible to simultaneously inflate the lateral tubes and the bottom of the boat.
Selon le même mode de réalisation, les passages entre la première ouverture ou la deuxième ouverture et la quatrième ouverture sont ouverts dans la position d'ouverture des moyens d'obstruction, et les passages entre la première ouverture ou la deuxième ouverture et la quatrième ouverture sont fermés dans la position de fermeture des moyens d'obstruction. According to the same embodiment, the passages between the first opening or the second opening and the fourth opening are open in the open position of the obstruction means, and the passages between the first opening or the second opening and the fourth opening are closed in the closed position of the obstruction means.
Cette disposition permet d'isoler chacune des chambres à air des boudins latéraux et du fond.  This arrangement makes it possible to isolate each of the air chambers of the lateral flanges and the bottom.
Avantageusement, la section de la quatrième ouverture est sous- d imensionnée par rapport aux sections de la prem ière ouverture et de la deuxième ouverture.  Advantageously, the section of the fourth opening is underdamped with respect to the sections of the first opening and the second opening.
Cette disposition permet de faire coïncider la fin du gonflage du fond, dont la chambre à air possède généralement un volume inférieur à celle des deux boudins latéraux, avec la fin de gonflage des chambres des boudins latéraux et donc de préserver le fond de surpressions ponctuelles dues au mouvement de pompe au court du gonflage.  This arrangement makes it possible to match the end of the bottom inflation, of which the air chamber generally has a smaller volume than that of the two lateral flanges, with the end of inflation of the chambers of the lateral flanges and thus to preserve the bottom of specific overpressures due pump movement during inflation.
Selon u n mode de réal isation, les moyens d'obstruction sont amovibles de l'enceinte.  According to a mode of real isation, the obstruction means are removable from the enclosure.
Cette disposition permet u n rem placement a isé des moyens d'obstructions, par exemple en cas de perte d'étanchéité et permet le dégonflage simultané et rapide des chambres à air de l'embarcation gonflable reliées au dispositif de gonflage.  This arrangement allows a neat placement of the means of obstructions, for example in case of loss of tightness and allows the simultaneous and rapid deflation of the air chambers of the inflatable boat connected to the inflation device.
La présente invention a également pour objet une embarcation gonflable comportant un dispositif de gonflage tel que décrit précédemment.  The present invention also relates to an inflatable boat comprising an inflation device as described above.

La figure 6 représente une embarcation gonflable équipée d'un dispositif de gonflage selon l'invention. Figure 5 shows a functional view of an inflation device according to a second embodiment. FIG. 6 represents an inflatable boat equipped with an inflation device according to the invention.
Comme illustré sur la figure 6, un dispositif de gonflage 100, 200 selon l'invention peut être utilisé pour le gonflage d'une embarcation gonflable 2 comprenant un boudin latéral droit 3, un boudin latéral gauche 4 et éventuellement un fond 4 comprenant chacun respectivement une chambre à air 31 , 41 , 51 indépendante ainsi que des moyens d'acheminement en air 32, 42, 52.  As illustrated in FIG. 6, an inflation device 100, 200 according to the invention can be used for inflating an inflatable boat 2 comprising a right lateral bead 3, a left lateral bead 4 and possibly a bottom 4 each comprising respectively an air chamber 31, 41, 51 independent as well as air conveying means 32, 42, 52.
Les chambres à air 31 , 41 des deux boudins latéraux 3, 4 présentent un même volume.  The air chambers 31, 41 of the two lateral tubes 3, 4 have the same volume.
Comme illustré sur les différents modes de réalisation présentés aux figures 1 à 4 et 5, un dispositif de gonflage 100, 200 selon l'invention comprend un corps étanche 6 comprenant une enceinte 7 présentant trois ouvertures 1 1 , 12, 13 de communication reliées entre elles.  As illustrated in the various embodiments presented in FIGS. 1 to 4 and 5, an inflation device 100, 200 according to the invention comprises a sealed body 6 comprising an enclosure 7 having three communication openings 1 1, 12, 13 connected between they.
La première ouverture 1 1 est destinée à être rel iée au moyen d'acheminement d'air 32 destiné à alimenter en air la chambre à air 31 du premier boudin latéral 3 de l'embarcation gonflable 2, la deuxième ouverture 12 est destinée à être reliée au deuxième moyen d'acheminement d'air 42 destiné à al imenter en a ir l a cham bre à a ir 41 du deuxième boudin latéral 4 de l'embarcation gonflable 2, la troisième ouverture 1 3 est destinée à être raccordée à une pompe de gonflage (non illustrée).  The first opening 1 1 is intended to be relé to the air conveying means 32 for supplying air to the air chamber 31 of the first lateral bead 3 of the inflatable boat 2, the second opening 12 is intended to be connected to the second air conveying means 42 for supplying the chamber to the chamber 41 to the second lateral flange 4 of the inflatable boat 2, the third opening 13 is intended to be connected to a pump inflation (not shown).
En outre, la première ouverture 1 1 et la deuxième ouverture 12 présentent u n même d iamètre i ntérieu r ou section afin de répartir équitablement l'air injecté par la pompe provenant de la troisième ouverture 13.  In addition, the first opening 11 and the second opening 12 have a same diameter or section in order to equitably distribute the air injected by the pump from the third opening 13.
Dans un premier mode de réalisation illustré aux figures 1 à 4, le d ispositif de gonflage 1 00 comporte une embase 101 réunissant les deux moyens d'acheminement en air 32, 42 des deux boudins latéraux 3, 4, et une base amovible 1 10 pouvant être reliée d'une part à l'embase 1 01 , et pouvant être reliée d'autre part soit au corps étanche 6 du dispositif de gonflage 100, par exemple lors d'une position de gonflage illustrée à la figure 4, soit à des moyens d'obturation 130 par exemple lors d'une position fermée illustrée à la figure 3 ou encore lors d'une position de dégonflage illustrée à la figure 2.  In a first embodiment illustrated in FIGS. 1 to 4, the inflation device 1 00 comprises a base 101 joining the two air conveying means 32, 42 of the two lateral socks 3, 4, and a removable base 1 10. which can be connected on the one hand to the base 1 01, and can be connected on the other hand to the sealed body 6 of the inflation device 100, for example during an inflation position illustrated in FIG. closing means 130 for example during a closed position illustrated in Figure 3 or in a deflation position illustrated in Figure 2.
Dans le mode de réalisation présenté, le corps étanche 6 est amovible, les moyens d'obturation 130 pouvant se substituer au corps étanche 6. L'embase 101 comporte un premier conduit 102 pouvant être relié aux moyens d'acheminement en air 32 du premier boudin latéral 3 de l'embarcation 2 et un deuxième conduit 103 pouvant être relié aux moyens d'acheminement en air 42 du deuxième boudin latéral 4 de l'embarcation gonflable 2. In the embodiment shown, the sealed body 6 is removable, the sealing means 130 can be substituted for the sealed body 6. The base 101 comprises a first duct 102 that can be connected to the air conveying means 32 of the first lateral flange 3 of the boat 2 and a second duct 103 that can be connected to the air conveying means 42 of the second lateral flange. 4 of the inflatable boat 2.
Chacun de ces conduits 102, 103 fait sailli dans le haut d'un corps 106 de l'embase 101 .  Each of these ducts 102, 103 projects into the top of a body 106 of the base 101.
Ce corps 1 06 se présente sous la forme d'un cylindre creux et comporte un filetage périphérique extérieur 107 dont la fonction sera décrite plus loin dans le texte.  This body 106 is in the form of a hollow cylinder and has an outer peripheral thread 107 whose function will be described later in the text.
Ce filetage 107 s'étend de façon circonférentielle depuis une extrémité haute extérieure du corps 1 06 jusqu'à un épaulement périphérique transversal 105 s'étendant vers l'extérieur de l'embase 101 assurant la fonction de soubassement pour la fixation du dispositif de gonflage 1 00 à une partie rigide de l'embarcation gonflable 2.  This thread 107 extends circumferentially from an outer upper end of the body 106 to a transverse peripheral shoulder 105 extending outwardly from the base 101 providing the underbody function for fixing the inflation device. 1 00 to a rigid part of the inflatable boat 2.
Les parties en saillie des conduits 102, 103 comportent quant à elles un épaulement annulaire extérieur 108 destiné à recevoir chacun un joint torique d'étanchéité 104.  The projecting portions of the ducts 102, 103 comprise an outer annular shoulder 108 for receiving each an O-ring seal 104.
Dans la position de fermeture illustrée à la figure 3 et dans la position de gonflage illustrée à la figure 4, la base amovible 1 10 est destinée à couvrir l'embase 1 01 et comprend une partie centrale 1 13 autour de laquelle est d isposée une partie périphérique 1 1 4 destinée à être manipulée par l'utilisateur du dispositif de gonflage 100.  In the closed position illustrated in FIG. 3 and in the inflation position illustrated in FIG. 4, the removable base 1 10 is intended to cover the base 1 01 and comprises a central part 1 13 around which is positioned a peripheral portion 1 1 4 to be manipulated by the user of the inflation device 100.
La partie centrale 1 1 3 et la partie périphérique 1 14 présentent toutes deux une forme générale cylindrique.  The central portion 1 1 3 and the peripheral portion 1 14 both have a generally cylindrical shape.
La partie centrale 1 13 comporte un filetage périphérique extérieur 1 1 9 dont la fonction sera décrite pl us loin dans le texte ainsi qu'une paroi disposée transversalement dans la forme cylindrique.  The central portion 1 13 has an outer peripheral thread 1 1 9 whose function will be described far in the text and a wall disposed transversely in the cylindrical shape.
La partie centrale 1 13 comporte également deux conduits d'air 1 1 1 , 1 12 faisant saillis de part et d'autre de cette paroi transversale et destinés à être disposés dans le prolongement des deux conduits 1 02, 103 de l'embase 101 .  The central part 1 13 also comprises two air ducts 1 1 1, 1 12 protruding on either side of this transverse wall and intended to be arranged in the extension of the two ducts 1 02, 103 of the base 101 .
Ces deux conduits d'air 1 1 1 , 1 12 comprennent chacun un dispositif anti-retour 8 de l'air empêchant l'air se trouvant dans l'un des deux boudins latéraux 3, 4 d'accéder au corps étanche 6 du dispositif de gonflage 100 dans les positions de gonflage et fermée. En outre, l'extrémité supérieure de chacune des portions des deux conduits d'air 1 1 1 , 1 12 faisant saillie de la paroi transversale est chanfreinée sur sa surface intérieure. These two air ducts 1 1 1, 1 12 each comprise a non-return device 8 of air preventing air in one of the two lateral flanges 3, 4 to access the sealed body 6 of the device inflation 100 in the inflation positions and closed. In addition, the upper end of each of the portions of the two air ducts 1 1 1, 1 12 protruding from the transverse wall is chamfered on its inner surface.
La partie centrale 1 13 de la base amovible 1 1 0 comporte un épaulement annulaire 1 1 7 ayant la fonction de butée et de guide pour un épaulement annulaire 1 1 8 disposé sur la partie périphérique 1 14 de la base amovible 1 10.  The central portion 1 13 of the removable base 1 1 0 comprises an annular shoulder 1 1 7 having the stop and guide function for an annular shoulder 1 1 8 disposed on the peripheral portion 1 14 of the removable base 1 10.
Ainsi, cette liaison mécanique permet le mouvement en rotation libre de la partie périphérique 1 14 autour de la partie centrale 1 13.  Thus, this mechanical connection allows the freely rotating movement of the peripheral portion 1 14 around the central portion 1 13.
La partie périphérique 1 14 comprend également sur sa face interne un filetage 1 15 destiné à coopérer avec le filetage 107 de l'embase 101 .  The peripheral portion 1 14 also comprises on its internal face a thread 1 15 intended to cooperate with the thread 107 of the base 101.
De plus, la partie centrale 1 13 comprend un épaulement annulaire transversal 1 1 6 destiné à venir comprimer le joint torique 1 04 disposé sur l'épaulement 108 de chacune des parties en saillie des conduits 102, 103 de l'embase 101 .  In addition, the central portion 1 13 comprises a transverse annular shoulder 1 1 6 intended to compress the O-ring 1 04 disposed on the shoulder 108 of each of the projecting portions of the ducts 102, 103 of the base 101.
Ainsi, lors de la pose de la base amovible 1 1 0 sur l'embase 1 01 , chacune des portions des conduits 1 1 1 , 1 12 faisant saillie vers le bas pénètrent progressivement par le haut des conduits 102, 103 de l'embase 101 .  Thus, during the installation of the removable base 1 1 0 on the base 1 01, each of the portions of the ducts 1 1 1, 1 12 projecting downwards progressively penetrate through the top of the ducts 102, 103 of the base 101.
La partie centrale 1 13 de la base amovible 1 10 est ainsi bloquée en rotation et la base amovible 1 1 0 descend en translation jusqu'à ce que le filetage 1 15 de la base amovible 1 10 atteigne le filetage 107 de l'embase 101 .  The central portion 1 13 of the removable base 1 10 is thus locked in rotation and the removable base 1 1 0 descends in translation until the thread 1 15 of the removable base 1 10 reaches the thread 107 of the base 101 .
Un mouvement de rotation de la partie périphérique 1 14 dans le sens anti-trigonométrique créé alors une transformation du mouvement du type vis-écrou qui entraîne alors davantage en translation la partie centrale 1 13 de la base amovible 1 1 0 jusqu'à ce que l'épaulement 1 16 atteigne les joints toriques 104 et les comprime pour assurer l'étanchéité entre l'embase 101 et la base amovible 1 10 du dispositif de gonflage 100.  A rotational movement of the peripheral portion 1 14 in the anti-trigonometric direction then creates a transformation of the screw-nut type movement which then causes more translation in the central portion 1 13 of the removable base 1 1 0 until the shoulder 1 16 reaches the O-rings 104 and compresses them to seal between the base 101 and the removable base 1 10 of the inflation device 100.
Afin d'augmenter cette étanchéité les diamètres des conduits 102, 103 et des conduits 1 1 1 , 1 12 sont sensiblement égaux au jeu près.  In order to increase this tightness, the diameters of the conduits 102, 103 and the ducts 11, 11 are substantially equal to the clearance.
Dans cette position, la base amovible 1 10 peut accueillir soit le corps étanche 6 pour un gonflage de l'embarcation gonflable 2, soit les moyens d'obturation 130 en position de fermeture après le gonflage ou stockage de l'embarcation 2 dégonflée.  In this position, the removable base 1 10 can accommodate either the sealed body 6 for inflating the inflatable boat 2, or the closure means 130 in the closed position after inflation or storage of the boat 2 deflated.
Dans ce mode de réalisation, le corps étanche 6 du dispositif de gonflage 1 00 est amovible et présente une forme générale en « Y » renversé dont les deux branches symétriques d u « Y » présentent chacune un coude 120 pour aligner les ouvertures 1 1 et 12 selon deux axes parallèles, chacun de ces axes étant coaxial avec un axe d'alignement d'un des conduits 1 1 1 , 1 12 de la base amovible 1 10. In this embodiment, the sealed body 6 of the inflation device 1 00 is removable and has a generally "Y" inverted shape whose two symmetrical branches of the "Y" each have a bend 120 to align the openings 1 1 and 12 along two parallel axes, each of these axes being coaxial with an alignment axis of one of the ducts 1 1 1, 1 12 of the removable base 1 10.
Chacune des ouvertures 1 1 , 12 présente un contour extérieur 121 biseauté afin de facilité leur insertion dans les conduits 1 1 1 , 1 12 de la base amovible 1 10.  Each of the openings January 1, 12 has an outer contour 121 beveled for ease of insertion into the conduits 1 1 1, 1 12 of the removable base 1 10.
La branche principale du « Y » forme quant à elle l'ouverture 13 pour la connexion à la pompe de gonflage.  The main branch of the "Y" forms the opening 13 for connection to the inflation pump.
Da n s ce mod e d e réa l i sation , les moyens d'obturation 130 comprennent une partie périphérique 132 libre en rotation autour d'une partie centrale 131 .  In this embodiment, the closure means 130 comprise a peripheral portion 132 free to rotate about a central portion 131.
La partie périphérique 132 est destinée à être manipulée par l'utilisateur du dispositif de gonflage 100.  The peripheral portion 132 is intended to be handled by the user of the inflation device 100.
La partie centrale 131 et la partie périphérique 132 présentent toutes deux une forme générale cylindrique.  The central portion 131 and the peripheral portion 132 both have a generally cylindrical shape.
La partie centrale 1 31 est reliée à la partie périphérique 132 par l'intermédiaire d'un axe fendu 137 fixé sensiblement au centre de la partie périphérique 132 traversant la partie centrale 131 au travers d'un orifice 139.  The central portion 1 31 is connected to the peripheral portion 132 via a split axis 137 fixed substantially in the center of the peripheral portion 132 through the central portion 131 through an orifice 139.
L'axe fendu 1 37 comprend un ergot circonférentiel 138 disposé sensiblement à une d istance sensiblement égale au jeu près à l'épaisseur traversée de la partie centrale 131 .  The split shaft 1 37 comprises a circumferential lug 138 disposed substantially at a distance substantially equal to the clearance at the thickness through which the central portion 131 passes.
Cet ergot circonférentiel 138 est biseauté dans le sens d'introduction de l'axe fendu 137 dans l'orifice 139.  This circumferential lug 138 is beveled in the direction of insertion of the split shaft 137 into the orifice 139.
Ainsi, cette forme en biseau ainsi que l'élasticité de l'axe fendu 137 conférée par sa fente facilite l'introduction de l'axe fendu 137 au travers l'orifice 139.  Thus, this beveled shape and the elasticity of the split shaft 137 conferred by its slot facilitates the introduction of the split axis 137 through the orifice 139.
La partie centrale 131 comporte également deux bouchons 134, 1 35 présentant une forme cyl indrique de d iamètre supérieur à ceux des conduits 1 1 1 , 1 12 de la base amovible 1 10.  The central portion 131 also comprises two plugs 134, 1 35 having a cylindrical shape greater than the diameter of the ducts 1 1 1, 1 12 of the removable base 1 10.
Le bouchon 134 et le bouchon 135 sont destinés à venir obstruer simultanément respectivement le conduit 1 1 1 et le conduit 1 12 dans la position fermée du dispositif de gonflage 1 00, ainsi ces deux bouchons 1 34, 1 35 sont alignés selon deux axes parallèles, chacun de ces axes étant coaxial avec un axe d'alignement d'un des conduits 1 1 1 , 1 12 de la base amovible 1 10. La partie périphérique 1 32 comporte quant à elle un filetage 133 sur sa face interne destiné à coopérer avec le filetage périphérique 1 19 de la partie centrale 1 13 de la base amovible 1 10. The stopper 134 and the stopper 135 are intended to simultaneously obstruct respectively the duct 1 1 1 and the duct 1 12 in the closed position of the inflator 1 00, thus these two plugs 1 34, 1 35 are aligned along two parallel axes , each of these axes being coaxial with an alignment axis of one of the ducts 1 1 1, 1 12 of the removable base 1 10. The peripheral portion 1 32 has meanwhile a thread 133 on its inner face intended to cooperate with the peripheral thread 1 19 of the central portion 1 13 of the removable base 1 10.
En outre, ces deux bouchons 1 34 , 1 35 sont bordés par deux butées 136 s'étendant longitudinalement aux axes des bouchons 134, 135 et de part et d'autre de l'orifice central 139.  In addition, these two plugs 1 34, 1 35 are bordered by two stops 136 extending longitudinally to the axes of the plugs 134, 135 and on either side of the central orifice 139.
Ainsi, lors de la pose des moyens d'obturation 130 sur la base amovible 1 10, les butées 136 glissent en translation entre les deux portions en saill ie des conduits 1 1 1 , 1 12 de la base amovible 1 10 jusqu' à ce que le filetage 133 de la partie périphérique 132 des moyens d'obturation 130 atteigne le filetage 1 19 de la partie centrale 1 13 de la base amovible 1 10.  Thus, during the installation of the closure means 130 on the removable base 1 10, the abutments 136 slide in translation between the two portions in projection of the ducts 1 1 1, 1 12 of the removable base 1 10 until that the thread 133 of the peripheral portion 132 of the closure means 130 reaches the thread 1 19 of the central portion 1 13 of the removable base 1 10.
La partie centrale 1 31 des moyens d 'obturation 1 30 est alors bloquée en rotation par l'action des butées 136 qui prennent appui sur les bords des portions en saillie des conduits 1 1 1 , 1 12 de la base amovible 1 10.  The central portion 1 31 of the closure means 1 30 is then locked in rotation by the action of the abutments 136 which bear on the edges of the protruding portions of the ducts 1 1 1, 1 12 of the removable base 1 10.
Un mouvement de rotation de la partie périphérique 1 32 dans le sens anti-trigonométrique créé une transformation du mouvement du type vis- écrou qui entraîne alors davantage en translation la partie centrale 131 des moyens d'obturation 130 jusqu'à ce que les bouchons 134, 135 atteigne les conduits 1 1 1 , 1 12 de la base amovible 1 10.  A rotational movement of the peripheral portion 1 32 in the anti-trigonometric direction creates a transformation of the screw-nut type movement which then more translates the central portion 131 of the closure means 130 until the plugs 134 135 reaches the ducts 1 1 1, 1 12 of the removable base 1 10.
Afin de rendre le dispositif de gonflage 100 hermétique, deux joints plans 141 en forme de disque et de diamètre sensiblement égal à celui des bouchons 1 34, 1 35, sont maintenus respectivement sur chacune des deux surfaces des bouchons 134, 135 venant au contact des conduits 1 1 1 , 1 12 par l'intermédiaire de deux axes comportant un épaulement annulaire 140 disposé respectivement au centre de chacune de ces surfaces et traversant leur joint plan 141 respectif.  In order to make the inflation device 100 hermetic, two planar joints 141 in the form of a disk and of diameter substantially equal to that of the plugs 1 34, 1 35, are respectively held on each of the two surfaces of the plugs 134, 135 coming into contact with the conduits 1 1 1, 1 12 via two axes having an annular shoulder 140 disposed respectively in the center of each of these surfaces and through their respective plane joint 141.
Ainsi, dans ce mode de réalisation du dispositif de gonflage 100, l'utilisateur pour gonfler l'embarcation gonflable 2 commencera tout d'abord par retirer les moyens d'obturation 130 puis engagera le corps 6 du dispositif de gonflage 100 dans la base amovible 1 10.  Thus, in this embodiment of the inflation device 100, the user for inflating the inflatable boat 2 will firstly remove the closure means 130 and then engage the body 6 of the inflation device 100 in the removable base 1 10.
Il connectera ensuite la pompe de gonflage sur la troisième ouverture 13 du corps 6 afin de gonfler simultanément les deux boudins latéraux 3, 4 de l'embarcation gonflable 2.  It will then connect the inflation pump to the third opening 13 of the body 6 to simultaneously inflate the two lateral tubes 3, 4 of the inflatable boat 2.
Une fois ceux-ci gonflés à la pression recommandée, l'utilisateur retirera le corps 6 de la base amovible 1 10 et le replacera par les moyens d'obturation 130. Pour dégonfler l'embarcation gonflable 2, l'utilisateur désolidarisera la base amovible 1 10 de l'embase 101 du dispositif de gonflage 100. Once inflated to the recommended pressure, the user will remove the body 6 of the removable base 1 10 and will replace it by the closure means 130. To deflate the inflatable boat 2, the user will disengage the removable base 1 10 from the base 101 of the inflation device 100.
Dans un deuxième mode de réal isation illustré à la figure 5, le d ispositif de gonflage 200 selon l'invention comprend toujours un corps étanche 6 comprenant une enceinte 7 mais présente quatre ouvertures 1 1 , 12, 13 et 14 de communication reliées entre elles.  In a second embodiment shown in FIG. 5, the inflation device 200 according to the invention always comprises a sealed body 6 comprising an enclosure 7 but has four communication openings 11, 12, 13 and 14 connected to each other. .
