Description

La présente invention concerne un raccord intermédiaire pour embout d'appareil respiratoire.The present invention relates to an intermediate connector for a breathing apparatus nozzle.

Elle concerne plus particulièrement les appareils respiratoires employés par les pompiers pour se protéger des gaz toxiques. Ces appareils comprennent un masque destiné à être fixé sur le visage de l'utilisateur. Ce masque est relié à un dispositif d'alimentation d'air par l'intermédiaire d'un raccord démontable.It relates more particularly to the respiratory devices used by firefighters to protect themselves from toxic gases. These devices include a mask intended to be fixed on the face of the user. This mask is connected to an air supply device via a removable connector.

Traditionnellement ces raccords sont des raccords à vis dont la douille femelle est portée par le masque alors que la douille mâle est portée par le dispositif d'alimentation en air.Traditionally, these fittings are screw fittings, the female socket of which is carried by the mask while the male socket is carried by the air supply device.

Plus récemment, les raccords ont été améliorés de manière à faciliter leur manipulation et fiabiliser la jonction. A cet effet, il a été proposé des raccords encliquetables dans lesquels l'une des douilles comporte des becs susceptibles de s'enclencher derrière la face d'arrêt d'une lèvre complémentaire de ces becs portée par l'autre douille. Les becs sont mobiles perpendiculairement à l'axe du raccord soit par l'effet d'une pression directement exercée sur eux soit par l'intermédiaire de boutons accessibles de l'extérieur, de manière à permettre l'encliquetage et le désencliquetage du raccord. De tels raccords sont par exemple décrits dans le brevet FR-2 537 695.More recently, the fittings have been improved so as to facilitate their handling and make the junction more reliable. To this end, snap-on fittings have been proposed in which one of the sockets has spouts capable of engaging behind the stop face of a lip complementary to these spouts carried by the other socket. The spouts are movable perpendicular to the axis of the fitting either by the effect of a pressure directly exerted on them or by means of buttons accessible from the outside, so as to allow the latching and unclipping of the fitting. Such connections are for example described in patent FR-2,537,695.

Certains des dispositifs d'alimentation en air sont reliés à une source d'air respirable sous pression et une légère surpression est prévue à l'intérieur du masque de manière à éviter la pénétration de gaz toxiques éventuellement présents à l'extérieur. Dans ce cas, il a été proposé, par exemple dans le brevet européen EP-0 091 843 de munir l'un des éléments du raccord d'un palpeur coopérant avec l'autre élément du raccord, qui commande la fermeture du dispositif d'alimentation en air lorsque le raccord n'est pas en position fermée. Au contraire, il établit l'alimentation lorsque le raccord est fermé.Some of the air supply devices are connected to a source of pressurized breathing air and a slight overpressure is provided inside the mask so as to avoid the penetration of toxic gases possibly present outside. In this case, it has been proposed, for example in European patent EP-0 091 843 to provide one of the elements of the connector with a feeler cooperating with the other element of the connector, which controls the closing of the device. air supply when the connector is not in the closed position. Instead, it turns on the power when the fitting is closed.

Le palpeur mobile parallèlement à l'axe de l'embout est libre ou enfoncé selon que l'embout est démonté ou monté sur le masque.The movable probe parallel to the axis of the tip is free or depressed depending on whether the tip is disassembled or mounted on the mask.

Pour différentes raisons, par exemple de compatibilté d'un même appareil respiratoire sur différents types de masques ou de normalisation, il est maintenant considéré préférable que l'embout de l'appareil respiratoire ne soit pas directement fixé sur le masque mais par un raccord intermédiaire.For different reasons, for example compatibility of the same respiratory device on different types of masks or standardization, it is now considered preferable that the end piece of the respiratory device is not directly fixed on the mask but by an intermediate connector. .

Actuellement il n'existe pas de raccord intermédiaire de ce type permettant d'assurer le fonctionnement convenable d'un palpeur libérant l'alimentation en air de l'appareil respiratoire lorsque l'ensemble de la jonction embout d'appareil respiratoire - raccord intermédiaire - masque est réalisée convenablement c'est-à-dire de manière étanche et seulement dans ce cas.Currently there is no intermediate connection of this type to ensure the proper functioning of a sensor releasing the air supply to the respiratory system when the entire junction of breathing apparatus endpiece - intermediate connection - mask is made properly, that is to say in a sealed manner and only in this case.

L'objectif de l'invention est de résoudre ce problème en proposant un raccord intermédiaire qui permette la liaison entre un embout encliquetable comportant un palpeur et une douille à vis femelle tout en assurant un fonctionnement convenable du palpeur.The objective of the invention is to solve this problem by proposing an intermediate connector which allows the connection between a snap-on end fitting comprising a feeler and a female screw socket while ensuring proper operation of the feeler.

A cet effet, il est proposé un raccord intermédiaire pour embout d'appareil respiratoire destiné à permettre la liaison entre un embout encliquetable comportant un palpeur mobile parallèlement à l'axe de l'embout et une première douille à vis du type comportant un corps muni à l'une de ses extrémités d'une douille encliquetable complémentaire de celle de l'embout et à l'autre extrémité d'une deuxième douille à vis destinée à coopérer avec la première douille à vis. Selon l'invention, ce raccord intermédiaire comporte une bague intérieure mobile en translation parallèlement à l'axe de raccord entre deux positions extrêmes. Le palpeur est actionné par la bague intérieure uniquement lorsque la liaison est complètement et correctement réalisée.To this end, an intermediate connector is proposed for the end piece of a breathing apparatus intended to allow the connection between a snap-on end piece comprising a movable feeler parallel to the axis of the end piece and a first screw socket of the type comprising a body provided at one of its ends of a snap-on socket complementary to that of the end piece and at the other end of a second screw socket intended to cooperate with the first screw socket. According to the invention, this intermediate connection comprises an inner ring movable in translation parallel to the connection axis between two extreme positions. The probe is actuated by the inner ring only when the connection is completely and correctly made.

L'invention sera décrite dans en détail en référence aux dessins dans lesquels :

  • - La figure 1 est une représentation générale du masque et de l'arrivée du système respiratoire.
  • - La figure 2 est une vue en coupe partielle des éléments du dispositif de liaison en position non assemblée.
  • - La figure 3 est une vue en coupe partielle des éléments du système de liaison en position assemblée.
The invention will be described in detail with reference to the drawings in which:
  • - Figure 1 is a general representation of the mask and the arrival of the respiratory system.
  • - Figure 2 is a partial sectional view of the elements of the connecting device in the unassembled position.
  • - Figure 3 is a partial sectional view of the elements of the connection system in the assembled position.

Le raccord intermédiaire 1 intervient dans la liaison entre le masque 2 et l'embout encliquetable 3 de l'appareil respiratoire. Le masque 2 est généralement muni d'une douille à vis femelle 4.The intermediate connector 1 intervenes in the connection between the mask 2 and the snap-on endpiece 3 of the respiratory system. The mask 2 is generally provided with a female screw socket 4.

On appelle ici respectivement douille mâle et douille femelle les deux éléments complémentaires d'une liaison de deux parties de tube s'engageant partiellement l'un dans l'autre.Here called respectively male socket and female socket the two complementary elements of a connection of two tube parts partially engaging one in the other.

La plupart des éléments de la jonction entre le masque et l'appareil respiratoire présentent une symétrie de révolution autour de l'axe 5.Most of the elements of the junction between the mask and the respiratory system have a symmetry of revolution around axis 5.

L'embout encliquetable 3 comporte un palpeur 31 mobile parallèlement à l'axe 5 de l'embout 3. Ce palpeur 31 est maintenu en position lorsqu'il est libre, par un ressort 32. Lorsqu'il est dans cette position libre, il commande la fermeture de l'alimentation en air de l'appareil respiratoire. Lorsque sous l'effet d'une action extérieure le palpeur est enfoncé à l'encontre du ressort 32, il commande l'alimentation d'air sous pression dans l'embout de l'appareil respiratoire.The snap-on end piece 3 comprises a probe 31 movable parallel to the axis 5 of the end piece 3. This probe 31 is held in position when it is free, by a spring 32. When it is in this free position, it controls the shutdown of the air supply to the respiratory system. When under the effect of an external action the feeler is pressed against the spring 32, it controls the supply of pressurized air into the nozzle of the respiratory system.

L'appareil respiratoire et le masque 2 peuvent avoir des origines diverses, il est donc souvent difficile de prévoir une adaptation directe de l'un sur l'autre. Le raccord intermédiaire de l'invention permet cette adaptation et assure le fonctionnement du palpeur 31.The respiratory system and the mask 2 can have various origins, so it is often difficult to provide for direct adaptation of one to the other. The intermediate connector of the invention allows this adaptation and ensures the operation of the probe 31.

Le raccord 1 comporte un corps 11 muni à l'une de ses extrémités d'une douille encliquetable 12 destinée à coopérer avec la douille 33 de l'embout 3 de l'alimentation en air et à son autre extrémité une douille à vis mâle 13 destinée à coopérer avec la douille à vis femelle 4.The connector 1 comprises a body 11 provided at one of its ends with a snap-on socket 12 intended to cooperate with the socket 33 of the nozzle 3 of the air supply and at its other end a male screw socket 13 intended to cooperate with the female screw socket 4.

Selon le type de masque utilisé, la douille à vis femelle 4 est soit directement portée sur le masque soit portée par un élément supplémentaire fixé sur le masque. Dans cette dernière hypothèse, cet élément supplémentaire est fixé fermement sur le masque de telle sorte qu'il ne risque pas d'être démonté lors de l'usage pratique du masque. Ces deux configurations sont donc analogues. La douille à vis femelle pouvant être supposée portée par le masque.Depending on the type of mask used, the female screw socket 4 is either directly carried on the mask or carried by an additional element fixed on the mask. In the latter case, this additional element is firmly fixed on the mask so that it does not risk being dismantled during the practical use of the mask. These two configurations are therefore analogous. The female screw socket can be assumed to be worn by the mask.

L'étanchéité de la douille encliquetable est réalisée par le joint torique 15 et l'étanchéité de la douille à vis par le joint 16 placé en appui sur un épaulement 41 de la partie femelle de la douille à vis et sur laquelle vient s'appuyer l'extrémité de la douille mâle 13.The sealing of the snap-on socket is carried out by the O-ring 15 and the sealing of the screw socket by the seal 16 placed in abutment on a shoulder 41 of the female part of the screw socket and on which comes to bear. the end of the male socket 13.

Le raccord intermédiaire 1 comporte une bague intérieure 14 mobile par rapport au corps 11 parallèlement à l'axe de la liaison 5. Le corps 11 du raccord intermédiaire 1 comporte une butée intérieure 111. Cette butée 111 coopère avec deux épaulements extérieurs 141, 142 de la bague intérieure 14. Ils sont chacun situés d'un côté de la butée 111 et limitent donc les déplacements de la bague 14. Un dispositif à ressort 5 rappelle la bague intérieure 14 dans sa position de repos dans laquelle l' épaulement 141 est en appui sur la butée 111 lorsque la bague intérieure est libre c'est-à-dire qu'elle n'est soumise à aucune action extérieure.The intermediate connector 1 has an inner ring 14 movable relative to the body 11 parallel to the axis of the connection 5. The body 11 of the intermediate connector 1 has an internal stop 111. This stop 111 cooperates with two external shoulders 141, 142 of the inner ring 14. They are each located on one side of the stop 111 and therefore limit the movements of the ring 14. A spring device 5 recalls the inner ring 14 in its rest position in which the shoulder 141 is in support on the stop 111 when the inner ring is free, that is to say that it is not subjected to any external action.

Au contraire, lorsque la douille à vis 4, 13 est fermée c'est-à-dire que la douille mâle 13 est engagée dans la douille femelle 4, la bague intermédiaire 14 est déplacée à l'encontre du système à ressort 5, l'épaulement 142 venant au contact de la butée 111.On the contrary, when the screw socket 4, 13 is closed, that is to say that the male socket 13 is engaged in the female socket 4, the intermediate ring 14 is moved against the spring system 5, l shoulder 142 coming into contact with stop 111.

La configuration du corps 11 est déterminée par rapport à celle de l'embout 3 de l'alimentation en air de telle sorte que, en l'absence de bague intérieure 14, aucun élément du corps 11 ne puisse se présenter face au palpeur mobile 31. Par contre la bague intérieure 14 a une configuration qui lui permet d'agir sur le palpeur 31 lorsqu'elle est en position active et de le libérer lorsqu'elle est en position de repos.The configuration of the body 11 is determined relative to that of the end piece 3 of the air supply so that, in the absence of an inner ring 14, no element of the body 11 can be present facing the movable probe 31 Against by the inner ring 14 has a configuration which allows it to act on the probe 31 when it is in the active position and to release it when it is in the rest position.

Le plus souvent le palpeur 31 est situé à la périphérie de l'embout 3. Le rayon intérieur du corps 11 est supérieur à la distance du palpeur 31 à l'axe 5 de telle sorte qu'il se trouve à l'intérieur du corps 11. Le rayon intérieur de la bague 14 est inférieur à cette même distance du palpeur 31 à l'axe 5. La course de la bague intérieure dans son déplacement parallèlement à l'axe 5 à l'intérieur du corps 11 est telle que lorsque la douille encliquetable est fermée, la bague intérieure appuie sur le palpeur lorsqu'elle est rapprochée de lui et le libère lorsqu'elle est éloignée.Most often the probe 31 is located at the periphery of the end piece 3. The internal radius of the body 11 is greater than the distance from the probe 31 to the axis 5 so that it is inside the body 11. The inner radius of the ring 14 is less than this same distance from the probe 31 to the axis 5. The stroke of the inner ring in its movement parallel to the axis 5 inside the body 11 is such that when the snap-in sleeve is closed, the inner ring presses on the probe when it is close to it and releases it when it is far away.

La bague intérieure 14 présente vers le palpeur une surface plane en forme de couronne qui lui permet de remplir sa fonction quelle que soit sa position angulaire autour de l'axe 5.The inner ring 14 has a flat surface in the shape of a crown towards the feeler which enables it to fulfill its function whatever its angular position around the axis 5.

Lorsque la douille encliquetable est ouverte, aucune action extérieure n'est produite sur le palpeur mobile 31 et donc, sous l'effet du ressort 32, il est maintenu dans sa position libre fermant l'alimentation en air du dispositif respiratoire.When the snap-on sleeve is open, no external action is produced on the movable probe 31 and therefore, under the effect of the spring 32, it is held in its free position closing the air supply to the respiratory device.

Lorsque la douille encliquetable 3, 12 est fermée, deux situations sont possibles. Si la douille à vis 4, 13 est ouverte, la bague intermédiaire 14 est maintenue par le ressort 6 dans sa position libre et le palpeur 31 dispose à l'intérieur du corps 11 d'une place suffisante pour rester lui-même en position libre. Si, au contraire, la douille à vis 4, 13 est fermée, la bague intérieure 14 étant comme nous l'avons vu déplacée à l'encontre du ressort 5 est rapprochée de l'embout 3 de l'appareil respiratoire. Elle exerce une pression par l'intermédiaire de sa face 143 sur le palpeur 31, le déplaçe à l'encontre du ressort 32 dans sa position enfoncée dans laquelle il commande l'alimentation en air de l'appareil respiratoire.When the snap-on socket 3, 12 is closed, two situations are possible. If the screw socket 4, 13 is open, the intermediate ring 14 is held by the spring 6 in its free position and the probe 31 has enough space inside the body 11 to remain itself in the free position . If, on the contrary, the screw socket 4, 13 is closed, the inner ring 14 being, as we have seen, moved against the spring 5, is brought closer to the nozzle 3 of the respiratory system. It exerts pressure via its face 143 on the probe 31, moves it against the spring 32 in its depressed position in which it controls the supply of air to the respiratory system.

Finalement, lors de la mise en oeuvre de ce dispositif, l'alimentation en air de l'appareil respiratoire n'est commandée par le palpeur mobile 31 que lorsque simultanément la douille encliquetable 3, 12 et la douille à vis 4, 13 sont fermées c'est-à-dire lorsque la liaison entre l'embout encliquetable 3 et la douille à vis 4 est convenablement et complètement réalisé.Finally, during the implementation of this device, the air supply to the respiratory system is only controlled by the movable probe 31 when simultaneously the snap-on socket 3, 12 and the screw socket 4, 13 are closed. that is to say when the connection between the snap-on end piece 3 and the screw socket 4 is suitably and completely made.

Selon un mode de réalisation préféré, le corps 11 comporte une jupe 112 qui recouvre la douille à vis lorsque celle-ci est fermée. Cela permet d'éviter que la douille à vis ne soit soumise directement à des conditions extérieures difficiles, par exemple à des projections de liquides.According to a preferred embodiment, the body 11 comprises a skirt 112 which covers the screw socket when the latter is closed. This prevents the screw socket from being subjected directly to difficult external conditions, for example splashing liquids.

De préférence, le corps 11 comporte des perforations 113 qui permettent à des liquides qui auraient pu s'accumuler entre la jupe 112 et la douille à vis femelle 4, soit par condensation soit à la suite de projections, de s'écouler et de ne pas rester au voisinage de la douille à vis.Preferably, the body 11 has perforations 113 which allow liquids which could have accumulated between the skirt 112 and the female screw socket 4, either by condensation or following projections, to flow and not not stay in the vicinity of the screw socket.

De préférence, afin de faciliter le montage du raccord intermédiaire, l'un au moins des épaulements de la bague 14 est déformable élastiquement de façon à permettre la mise en place de la bague 14 dans le corps 11.Preferably, in order to facilitate the mounting of the intermediate connector, at least one of the shoulders of the ring 14 is elastically deformable so as to allow the positioning of the ring 14 in the body 11.

De préférence, le dispositif à ressort 5 est constitué d'un ressort à boudin entourant la bague 14 et placé lors du montage de la bague 14 à l'intérieur du corps 11 en appui d'une part sur la butée 111 et d'autre part sur l'épaulement 142. Afin d'améliorer le maintien de ce ressort 5, un logement peut être prévu à l'intérieur de l'épaulement 142 dans lequel le ressort à boudin s'engage partiellement.Preferably, the spring device 5 consists of a coil spring surrounding the ring 14 and placed during the mounting of the ring 14 inside the body 11 bearing on the one hand on the stop 111 and on the other hand part on the shoulder 142. In order to improve the retention of this spring 5, a housing can be provided inside the shoulder 142 in which the coil spring partially engages.

Le raccord intermédiaire de l'invention permet donc d'assurer une liaison fiable entre un masque et un appareil respiratoire tout en permettant l'utilisation à toutes fins souhaitées d'un palpeur mobile parallèlement à l'axe de l'embout et détectant la fermeture de la jonction. Ce raccord intermédiaire permet d'associer un appareil respiratoire et un masque d'origines différentes.The intermediate connector of the invention therefore ensures a reliable connection between a mask and a respiratory device while allowing the use for all desired purposes of a movable probe parallel to the axis of the nozzle and detecting closure of the junction. This intermediate connection makes it possible to associate a breathing apparatus and a mask of different origins.
