Description

La présente invention est relative à un système de perforation d'une cartouche de gaz, permettant de libérer, en cas de nécessité, un gaz comprimé (généralement du CO₂) contenu dans ladite cartouche à usage unique, en vue d'actionner divers éléments pneumatiques, notamment des dispositifs assurant la sécurité en cas d'incendie, et plus particulièrement des systèmes de désenfumage.The present invention relates to a system for perforating a gas cartridge, making it possible to release, if necessary, a compressed gas (generally CO₂) contained in said single-use cartridge, in order to actuate various pneumatic elements , in particular devices ensuring safety in the event of fire, and more particularly smoke extraction systems.

Les cartouches de gaz comprimé actuellement utilisées sont obturées par un opercule, généralement métallique, qui est perforé, lors de l'emploi, par un percuteur muni d'une pointe de forme appropriée, prévu sur le système de perforation. Dès que la cartouche de gaz a été utilisée, elle doit être remplacée par une nouvelle cartouche remplie de gaz comprimé et obturée par un opercule vierge, afin de remettre en position d'attente tout le système de commande et de sécurité constitué par le percuteur et les éléments pneumatiques de dispositif de sécurité, ce dernier étant alors de nouveau prêt à être actionné.The compressed gas cartridges currently used are closed by a cover, generally metallic, which is perforated, during use, by a striker provided with a tip of suitable shape, provided on the perforation system. As soon as the gas cartridge has been used, it must be replaced by a new cartridge filled with compressed gas and closed with a blank seal, in order to return to the standby position the entire control and safety system constituted by the striker and the pneumatic elements of the safety device, the latter then being again ready to be actuated.

A l'heure actuelle, aucun matériel de sécurité du type décrit ci-dessus ne permet de contrôler visuellement l'état de l'opercule d'obturation de la cartouche de gaz et, par conséquent, il n'est pas possible de se rendre compte par un examen purement optique, si la cartouche de gaz du dispositif de sécurité est vide ou pleine. Il est même possible, avec certains matériels, que la cartouche en soit absente, alors que le percuteur est apparemment armé. Il résulte de cet inconvénient qu'une installation de désenfumage munie d'un tel dispositif peut s'avérer dangereuse car inopérante en cas de sinistre. La présente invention s'est donc fixé pour objectif d'apporter un système de perforation de cartouche de gaz offrant la certitude, par une simple observation visuelle, que le percuteur est muni d'une cartouche à opercule vierge, donc pleine de gaz comprimé.At present, no security equipment of the type described above makes it possible to visually check the state of the sealing cap of the gas cartridge and, therefore, it is not possible to surrender account by a purely optical examination, if the gas cartridge of the safety device is empty or full. It is even possible, with certain materials, that the cartridge is absent, while the striker is apparently armed. It follows from this drawback that a smoke extraction installation fitted with such a device can prove to be dangerous because it does not work in the event of a disaster. The present invention has therefore set itself the objective of providing a gas cartridge perforation system offering the certainty, by a simple visual observation, that the striker is provided with a blank cartridge cartridge, therefore full of compressed gas.

En conséquence, cette invention concerne un système de perforation de cartouches de gaz comprimé obturées par un opercule, généralement métallique, à l'aide d'un percuteur muni d'une pointe de forme appropriée, caractérisé en ce qu'il comprend :
- un corps muni d'un alésage axial dans lequel est logée une tige dont la pointe vient en appui sur l'opercule de la cartouche de gaz comprimé;
- un levier de commande agissant sur l'extrémité de la tige, ou solidaire de celle-ci dont la position permet de vérifier si l'opercule de la cartouche en place dans le système est vierge ;
- un mécanisme approprié, utilisant une énergie intrinsèque telle que la gravité, la détente des gaz, un ressort agissant sur la tige ou le levier de commande, ayant pour objet d'interdire au système d'être en position d'attente alors que la cartouche est absente ou perforée ; et
- un dispositif empêchant tout retour en position d'attente du système sous l'effet de la poussée des gaz liberés par la perforation de l'opercule de la cartouche, ledit dispositif devant être débrayé pour la mise en place d'une cartouche de remplacement, qui met le système en position d'attente.Consequently, this invention relates to a system for perforating compressed gas cartridges closed by a cover, generally metallic, using a striker provided with a tip of suitable shape, characterized in that it comprises:
- A body provided with an axial bore in which is housed a rod whose tip comes to bear on the cover of the compressed gas cartridge;
- a control lever acting on the end of the rod, or integral with the latter, the position of which makes it possible to check whether the seal of the cartridge in place in the system is blank;
- an appropriate mechanism, using intrinsic energy such as gravity, gas expansion, a spring acting on the rod or the control lever, intended to prohibit the system from being in the waiting position while the cartridge is missing or perforated; and
a device preventing any return to the standby position of the system under the effect of the thrust of the gases released by the perforation of the cartridge seal, said device having to be disengaged for the installation of a replacement cartridge , which puts the system in the standby position.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif. Sur les dessins :

  • - La figure 1 est une vue en coupe axiale longitudinale d'un système objet de cette invention, en position dite "d'attente", c'est à dire avec une cartouche de gaz pleine ;
  • - La figure 2 représente la partie supérieure du système de la figure 1, tournée de 90°, avec le levier de commande et un axe de blocage ;
  • - Les figures 3 et 4 sont des vues similaires aux figures 1 et 2, après perforation de l'opercule de la cartouche de gaz par la pointe du percuteur ; et
  • - Les figures 5 et 6 sont des vues similaires aux figures 1 et 2 représentant le dispositif sans la cartouche.
Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawings which illustrate an embodiment thereof devoid of any limiting character. In the drawings:
  • - Figure 1 is a longitudinal axial sectional view of a system object of this invention, in the so-called "waiting" position, that is to say with a full gas cartridge;
  • - Figure 2 shows the upper part of the system of Figure 1, rotated 90 °, with the control lever and a locking pin;
  • - Figures 3 and 4 are views similar to Figures 1 and 2, after perforation of the seal of the gas cartridge by the tip of the striker; and
  • - Figures 5 and 6 are views similar to Figures 1 and 2 showing the device without the cartridge.

En se référant aux dessins et plus particulièrement aux figures 1 et 2, on voit que le système de percussion des cartouches de gaz selon l'invention, comprend un corps 10 muni d'un alésage axial longitudinal 12 dans lequel peut coulisser la tige 14 du percuteur, munie d'une pointe 16 de forme appropriée, conçue de façon à perforer l'opercule 18 qui obture, comme connu, la cartouche de gaz comprimé 20. Comme on le voit sur le dessin, l'extrémité de la cartouche 20 munie de l'opercule d'obstruction 18 est vissée sur le corps 10 avec une interposition d'un joint d'étanchéite 22.Referring to the drawings and more particularly to FIGS. 1 and 2, it can be seen that the percussion system of the gas cartridges according to the invention comprises a body 10 provided with a longitudinal axial bore 12 in which the rod 14 of the striker, provided with a tip 16 of suitable shape, designed to perforate the cover 18 which closes, as known, the compressed gas cartridge 20. As can be seen in the drawing, the end of the cartridge 20 provided of the obstructing cap 18 is screwed onto the body 10 with the interposition of a seal 22.

Dans une chambre 24, débouchant sur l'alésage 12, est positionnée une douille 26 rappelée par un ressort 28, la disposition reltive de cette douille 26, de la tige du percuteur 14 et du ressort 28 étant telle que l'action du ressort s'exerce sur l'opercule 18 par la douille 26 et non par la pointe 16 du percuteur. A cet effet, on prévoit un jeu "j" entre la douille 26 et la pointe 16, la distance "d" (figure 1) représentant la course de la pointe du percuteur.In a chamber 24, opening onto the bore 12, is positioned a sleeve 26 returned by a spring 28, the relative arrangement of this sleeve 26, the striker rod 14 and the spring 28 being such that the action of the spring s 'exerts on the cover 18 by the sleeve 26 and not by the tip 16 of the striker. To this end, a clearance "j" is provided between the sleeve 26 and the tip 16, the distance "d" (FIG. 1) representing the stroke of the tip of the striker.

La tige du percuteur est actionnée manuellement à l'aide d'un levier 30, venant appuyer sur la tête 32 de la tige 14, comme on le verra ci-­après. Le corps 10 est pourvu d'un alésage borgne 34 recevant une tige de blocage 38 à extrémité 38 en forme de piston rappelé par un ressort 40, l'extrémité 38 de la tige de blocage étant disposée de manière à pouvoir venir en prise, au moins partiellement, dans une gorge 42 prévue dans la tête 32 de la tige du percuteur.The striker rod is actuated manually using a lever 30, pressing on the head 32 of the rod 14, as will be seen below. The body 10 is provided with a blind bore 34 receiving a locking rod 38 at the end 38 in the form of a piston returned by a spring. 40, the end 38 of the locking rod being arranged so as to be able to engage, at least partially, in a groove 42 provided in the head 32 of the striker rod.

Lorsque le percuteur est armé, c'est à dire dans la position d'attente illustrée par les figures 1 et 2, la douille 26 prend appui sur l'opercule 18, l'action du ressort 28 s'exerçant sur la douille. La pointe 16, prenant appui sur l'opercule 18, maintien le levier d'actionnement 30 en position haute, indiquant qu'une cartouche est en place dans le système et que l'opercule de cette cartouche 20 est vierge.When the striker is cocked, that is to say in the standby position illustrated by FIGS. 1 and 2, the sleeve 26 is supported on the cover 18, the action of the spring 28 being exerted on the sleeve. The tip 16, bearing on the cover 18, maintains the actuation lever 30 in the high position, indicating that a cartridge is in place in the system and that the cover of this cartridge 20 is blank.

Lorsque l'utilisateur appui sur le levier 30 pour manoeuvrer le percuteur (figures 3 et 4), le levier 30 appuyant sur la tête 32, repousse la tige du percuteur au travers de l'alésage 24 et de la douille 26, qui appuie toujours sur la circonférence de l'opercule 18 de la cartouche de gaz. La pointe 16 poussée par la tige 14, vient alors perforer l'opercule dans sa zone centrale.When the user presses the lever 30 to operate the striker (FIGS. 3 and 4), the lever 30 pressing on the head 32, pushes the rod of the striker through the bore 24 and the socket 26, which always presses on the circumference of the cover 18 of the gas cartridge. The point 16 pushed by the rod 14, then perforates the cover in its central area.

L'extrémité 38 de la tige de hlocage 36, rappelée par le ressort 40 vient se loger dans la gorge 42 de la tête 32 de la tige du percuteur en empêchant que la pression de gaz ne fasse remonter la tige 14. Compte tenu de la liaison ainsi réalisée entre la tige du percuteur 14 et le levier de commande 30, il n'est pas possible de simuler le fait que l'opercule 18 de la cartouche en place dans le système n'ait pas été perforé, car le levier 30 ne peut pas se maintenir en position haute en raison de sa masse et, éventuellement, d'un ressort de rappel.The end 38 of the hoisting rod 36, recalled by the spring 40, is housed in the groove 42 of the head 32 of the striker rod while preventing the gas pressure from raising the rod 14. Taking into account the link thus produced between the striker rod 14 and the control lever 30, it is not possible to simulate the fact that the cover 18 of the cartridge in place in the system has not been perforated, because the lever 30 cannot be held in the high position due to its mass and possibly a return spring.

La position du levier 30, qui ne peut pas être modifiée, permet donc de vérifier que le système n'est plus en position d'attente.The position of the lever 30, which cannot be modified, therefore makes it possible to verify that the system is no longer in the standby position.

Les figures 5 et 6 représentent le système selon l'invention, sans la cartouche de gaz comprimé. On voit que la douille 26, repoussée par le ressor 28, est descendue en fin de course, en entraînant la tige 14 du percuteur par la goupille 13, et que l'axe de blocage 36-38 est logé dans la gorge 42 de la tête 32, le levier 30 étant en position basse.Figures 5 and 6 show the system according to the invention, without the compressed gas cartridge. It can be seen that the sleeve 26, pushed back by the spring 28, is lowered at the end of the stroke, by driving the rod 14 of the striker by the pin 13, and that the locking pin 36-38 is housed in the groove 42 of the head 32, the lever 30 being in the low position.

L'observateur détecte, sans risque d'erreur, que le système n'est pas en position d'attente.The observer detects, without risk of error, that the system is not in the waiting position.

On remarquera que toute tentative pour faire remonter la tige 14 du percuteur et sa pointe 16, seule ou avec la douille 26, par une impulsion manuelle, ne peut avoir pour conséquence le maintien du levier 30 en position haute. En effet, dès que l'action cesse sur la tige 14 et la douille 26, le ressort 28 repousse vers le bas la douille 26 ainsi que la tige 15 et sa pointe 16, grâce à la goupille 13, et le levier est ramené en position basse.It will be noted that any attempt to raise the rod 14 of the striker and its tip 16, alone or with the sleeve 26, by manual impulse, cannot have the consequence of maintaining the lever 30 in the high position. Indeed, as soon as the action ceases on the rod 14 and the sleeve 26, the spring 28 pushes down the sleeve 26 as well as the rod 15 and its tip 16, by means of the pin 13, and the lever is brought back in low position.

De même, le fait de remettre en place dans le système une cartouche dont l'opercule a déjà été perforé ne peut ramener le levier 30 en position haute. En effet, la circonférence externe de l'opercule 18, toujours en place malgré la perforation de la partie centrale par la pointe 16, soutient la douille 26 et décharge la pointe 16 de l'action du ressort, mais la résultante du frottement du joint 15 de la tige du percuteur sur le corps 10, qui est de l'ordre du dixième de l'effort nécessaire à la pointe 16 pour perforer l'opercule, a pout effet d'engager la pointe dans le trou précédemment perforé dans l'opercule. Il en résulte que la pointe 16 reste en position basse : donc, le levier 30 reste également en position basse, indiquant que l'opercule de la cartouche est perforé.Similarly, the fact of replacing in the system a cartridge whose cover has already been perforated can not return the lever 30 in the high position. Indeed, the outer circumference of the cover 18, still in place despite the perforation of the central part by the tip 16, supports the sleeve 26 and discharges the tip 16 from the action of the spring, but the result of the friction of the joint 15 of the striker rod on the body 10, which is of the order of one tenth of the force required by the tip 16 to perforate the cover, has the effect of engaging the tip in the hole previously perforated in the operculum. As a result, the tip 16 remains in the low position: therefore, the lever 30 also remains in the low position, indicating that the cartridge seal is perforated.

Par contre, le fait de positionner dans le dispositif une cartouche à opercule vierge, donc pleine de gaz comprimé, réarme le percuteur, après avoir repoussé l'axe de blocage 36. La douille 26 est alors en appui sur l'opercule 18, et elle décharge la pointe 16 de l'action du ressort 28. Par conséquent, la pointe 16 de la tige du percuteur n'exerce sur l'opercule 18 que la résultante de frottement du joint 15, qui est nettement insuffisante pour perforer l'opercule. Dès que la cartouche est convenablement positionnée dans le dispositif, la pointe 16 du percuteur est en position haute, et le levier 30 indique que le percuteur est réarmé.On the other hand, the fact of positioning in the device a cartridge with a virgin cover, therefore full of compressed gas, resets the striker, after having pushed back the locking pin 36. The socket 26 is then in abutment on the cover 18, and it discharges the tip 16 from the action of the spring 28. Consequently, the tip 16 of the striker rod exerts on the cover 18 only the resultant of friction of the seal 15, which is clearly insufficient to perforate the cover . As soon as the cartridge is properly positioned in the device, the tip 16 of the striker is in the high position, and the lever 30 indicates that the striker is reset.

L'observation optique de la position du levier 30 peut être facilitée à l'aide d'un voyant mécanique ou électrique, commandé par un contact électrique actionné par le système.Optical observation of the position of the lever 30 can be facilitated using a mechanical or electrical indicator light, controlled by an electrical contact actuated by the system.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représenté, mais qu'elle en englobe toutes les variantes.It remains to be understood that this invention is not limited to the embodiment described and shown, but that it encompasses all variants thereof.
