- the object of the invention is to use an inflatable enclosure.
- French Patent Application No. 2,265,666 describes an inflatable jack, but it requires a source of compressed air to inflate the enclosure. Such a source is not available on board an automobile and this jack cannot be used as an emergency jack for a driver.
- the invention overcomes all these drawbacks.
- the invention therefore relates to a pneumatic control system comprising an inflatable enclosure, characterized in that the enclosure is waterproof and is made of flexible and non-elastic material, and in that it comprises, fixed in the wall of the enclosure, a cartridge holder intended to receive in a sealed manner and in a fixed or removable manner a pyrotechnic cartridge so that the pyrotechnic charge is directed towards the interior of the enclosure.
- This system is therefore applicable to a car jack.
- the invention is applicable to a control system of a screwing / unscrewing device, characterized in that it also comprises, fixed in the wall of the enclosure, a mounting ring intended to receive in leaktight manner and fixed or removable way an outlet conduit connectable to the pneumatic control input of a pneumatic screwing / unscrewing device.
- This system includes an enclosure made of flexible material and as gas tight as possible.
- the wall of the enclosure has an access with, sealed, a pyrotechnic cartridge or a cartridge holder. It is capable of receiving a fixed or removable pyrotechnic cartridge.
- the pyrotechnic cartridge mounted in the wall of the enclosure has an electrical connection system accessible from outside the enclosure and making it possible to cause an electrical spark in the cartridge by injection of a current, which triggers the ignition of the pyrotechnic powder charge.
- the cartridge has a opening towards the interior of the enclosure.
- the evolution of gas which occurs causes the inflation of the enclosure as shown in FIG. 1b.

Abstract
Description
L'invention concerne un système de commande pneumatique, son application à un système élévateur tel qu'un cric de voiture ainsi que son application à la commande d'un appareil visseur/dévisseur pneumatique.The invention relates to a pneumatic control system, its application to a lifting system such as a car jack as well as its application to the control of a pneumatic screwing / unscrewing device.
Le cric mécanique actuellement utilisé sur les véhicules est souvent source de problèmes quant à son utilisation par des personnes non expérimentées.The mechanical jack currently used on vehicles is often a source of problems with its use by inexperienced people.
Les principaux inconvénients liés aux systèmes actuels sont les suivants :
- 1 - Le placement dans le véhicule
- 2 - La saleté due aux matières grasses dont le matériel est imprégné (indispensable pour le bon fonctionnement)
- 3 - La mise en oeuvre
- 4 - Les efforts à déployer nécessaires pour par exemple soulever les véhicules et débloquer les boulons de roues
- 5 - La nature des terrains de mise en oeuvre (terrain uniforme et peu pentu).
- 1 - Placement in the vehicle
- 2 - Dirt due to fatty substances in which the material is impregnated (essential for proper functioning)
- 3 - The implementation
- 4 - The efforts to be deployed, for example to lift the vehicles and unlock the wheel bolts
- 5 - The nature of the fields of implementation (uniform and slightly sloping ground).
Ce matériel qui demeure rustique et peu cher n'en demeure pas moins un mauvais produit qui rebute bon nombre d'utilisateurs potentiels quant à son utilisation (femmes, personnes âgées, etc).This material which remains rustic and inexpensive nonetheless remains a bad product which puts off a good number of potential users as for its use (women, old people, etc).
De même, les roues d'une automobile sont souvent bloquées à l'excès. En cas de crevaison, leur déblocage est souvent source de "tours de reins" et problématique pour nombre de conducteurs.Likewise, the wheels of an automobile are often locked to excess. In the event of a puncture, unlocking them is often a source of "backache" and problematic for many drivers.
Le système de l'invention fournit un système adaptable tout aussi bien pour débloquer les roues d'une automobile que pour servir de cric en vue de changer une roue crevée.The system of the invention provides an adaptable system as well for unlocking the wheels of an automobile as for serving as a jack for changing a punctured wheel.
L'invention a pour objet d'utiliser une enceinte gonflable.The object of the invention is to use an inflatable enclosure.
La Demande de Brevet français n° 2 265 666 décrit un cric gonflable, mais il nécessite une source d'air comprimé pour gonfler l'enceinte. Une telle source n'est pas disponible à bord d'une automobile et ce cric ne peut servir de cric de secours pour un conducteur.French Patent Application No. 2,265,666 describes an inflatable jack, but it requires a source of compressed air to inflate the enclosure. Such a source is not available on board an automobile and this jack cannot be used as an emergency jack for a driver.
L'invention permet de résoudre tous ces inconvénients.The invention overcomes all these drawbacks.
L'invention concerne donc un système de commande pneumatique comprenant une enceinte gonflable, caractérisé en ce que l'enceinte est étanche et est en matériau souple et non élastique, et en ce qu'il comporte, fixé dans la paroi de l'enceinte, un porte-cartouche destiné à recevoir de manière étanche et de manière fixe ou amovible une cartouche pyrotechnique de façon que la charge pyrotechnique soit dirigée vers l'intérieur de l'enceinte.The invention therefore relates to a pneumatic control system comprising an inflatable enclosure, characterized in that the enclosure is waterproof and is made of flexible and non-elastic material, and in that it comprises, fixed in the wall of the enclosure, a cartridge holder intended to receive in a sealed manner and in a fixed or removable manner a pyrotechnic cartridge so that the pyrotechnic charge is directed towards the interior of the enclosure.
Ce système est donc applicable à un cric de voiture.This system is therefore applicable to a car jack.
De plus l'invention est applicable à un système de commande d'un appareil visseur/dévisseur, caractérisé en ce qu'il comporte également, fixé dans la paroi de l'enceinte, une bague de montage destinée à recevoir de manière étanche et de manière fixe ou amovible un conduit de sortie raccordable à l'entrée de commande pneumatique d'un appareil visseur/dévisseur pneumatique.In addition, the invention is applicable to a control system of a screwing / unscrewing device, characterized in that it also comprises, fixed in the wall of the enclosure, a mounting ring intended to receive in leaktight manner and fixed or removable way an outlet conduit connectable to the pneumatic control input of a pneumatic screwing / unscrewing device.
Les différents objets et caractéristiques de l'invention apparaîtront plus clairement dans la description qui va suivre et dans les figures annexées qui représentent:
- les figures 1a et 1b, un exemple de réalisation simplifié du système de l'invention ;
- les figures 2a à 2c, un exemple d'application de l'invention à un élévateur tel qu'un cric d'automobile ;
- les figures 3a à 3c, des vues de détails des dispositifs de la figure 2a ;
- la figure 4, un exemple d'application de l'invention à un système visseur/dévisseur.
- Figures 1a and 1b, a simplified embodiment of the system of the invention;
- FIGS. 2a to 2c, an example of application of the invention to a lift such as a car jack;
- Figures 3a to 3c, detailed views of the devices of Figure 2a;
- Figure 4, an example of application of the invention to a screw / unscrew system.
En se reportant aux figures 1a et 1b, on va donc tout d'abord décrire un exemple général de réalisation du système de commande pneumatique selon l'invention. Ce système comporte une enceinte en matériau souple et le plus étanche possible au gaz.Referring to Figures 1a and 1b, we will therefore first describe a general embodiment of the pneumatic control system according to the invention. This system includes an enclosure made of flexible material and as gas tight as possible.
La paroi de l'enceinte comporte un accès avec, scellé de manière étanche, une cartouche pyrotechnique ou un porte-cartouche. Celui-ci est capable de recevoir de manière fixe ou amovible une cartouche pyrotechnique. La cartouche pyrotechnique montée dans la paroi de l'enceinte possède un système de connexion électrique accessible de l'extérieur de l'enceinte et permettant de provoquer une étincelle électrique dans la cartouche par injection d'un courant, ce qui déclenche l'inflammation de la charge de poudre pyrotechnique. La cartouche comporte une ouverture vers l'intérieur de l'enceinte. Ainsi, lors de l'inflammation de la poudre, le dégagement de gaz qui se produit provoque le gonflage de l'enceinte comme représenté en figure 1b. L'enceinte étant en matériau non élastique, elle acquiert avec une pression suffisante un aspect de rigidité. Elle peut donc être utilisée pour deux fonctions possibles soit comme dispositif pour exercer une force, soit comme réserve de gaz comprimé.The wall of the enclosure has an access with, sealed, a pyrotechnic cartridge or a cartridge holder. It is capable of receiving a fixed or removable pyrotechnic cartridge. The pyrotechnic cartridge mounted in the wall of the enclosure has an electrical connection system accessible from outside the enclosure and making it possible to cause an electrical spark in the cartridge by injection of a current, which triggers the ignition of the pyrotechnic powder charge. The cartridge has a opening towards the interior of the enclosure. Thus, during the ignition of the powder, the evolution of gas which occurs causes the inflation of the enclosure as shown in FIG. 1b. The enclosure being made of non-elastic material, it acquires an appearance of rigidity with sufficient pressure. It can therefore be used for two possible functions either as a device to exert a force or as a reserve of compressed gas.
La première fonction sera appliquée dans la description qui va suivre dans un système élévateur et la deuxième fonction sera appliquée dans un système visseur/dévisseur.The first function will be applied in the description which follows in an elevator system and the second function will be applied in a screw / unscrew system.
En se reportant aux figures 2a à 2c, on va donc décrire une application de l'invention à un système élévateur.Referring to Figures 2a to 2c, we will therefore describe an application of the invention to a lifting system.
On retrouve l'enceinte gonflable 1 en matériau étanche et non élastique. Un porte-cartouche 3 est scellé dans la paroi de l'enceinte 1. De préférence, le porte-cartouche 3 est scellé dans une zone renforcée 30 de l'enceinte.We find the
Selon une variante de réalisation non représentée, au lieu d'avoir un porte-cartouche scellé dans la paroi de l'enceinte, on peut prévoir que ce soit une cartouche pyrotechnique qui soit directement scellée. L'enceinte n'est alors utilisable qu'une seule fois.According to an alternative embodiment, not shown, instead of having a cartridge holder sealed in the wall of the enclosure, provision may be made for a pyrotechnic cartridge to be directly sealed. The speaker can only be used once.
Le porte-cartouche 3 comporte des moyens pour monter une cartouche pyrotechnique de façon étanche. Le porte-cartouche est alors adapté à la cartouche 10 qu'il doit recevoir. Le montage peut être à vis ou par encliquetage et l'étanchéité peut se faire à l'aide de joints tels que des joints toriques.The
L'enceinte 1 comporte des surfaces antidérapantes 2 prévues pour être en contact avec la charge à soulever et la pièce d'appui (le sol dans le cas d'un cric de voiture). Ces surfaces antidérapantes peuvent de façon simple être constituées d'une bande entourant l'enceinte 1. De cette façon, en prévoyant pour l'enceinte 1 une forme ovale ou cylindrique lorsqu'elle est gonflée, l'utilisateur peut placer l'enceinte sous la charge à soulever sans se préoccuper de l'orientation de l'enceinte autour de l'axe XX'.The
L'enceinte 1 peut également être munie d'une béquille 4 qui est reliée en un point supérieur de l'enceinte lorsqu'elle est gonflée. Ainsi lorsque l'utilisateur gonflera l'enceinte, la béquille 4 se placera automatiquement verticalement sous la charge de façon qu'en cas d'incident (dégonflage de l'enceinte), la charge soulevée soit maintenue soulevée par la béquille.The
Selon une variante de réalisation, la zone renforcée comporte une bague de montage 31 fixée de manière étanche. Cette bague de montage permet de brancher un appareil visseur/dévisseur à commande pneumatique 6 à l'aide d'un conduit.According to an alternative embodiment, the reinforced zone comprises a
Ainsi si le système élévateur est un cric de voiture, l'utilisateur en cas de crevaison peut gonfler une première fois l'enceinte en plaçant une cartouche dans le porte-cartouche 3 et en déclenchant la charge pyrotechnique. L'utilisateur branche le visseur/dévisseur 6 à la bague de montage 31. ll peut alors débloquer les écrous de fixation de la roue du véhicule à changer. Ensuite, il place l'enceinte 1 sous le véhicule. Il regonfle l'enceinte à l'aide d'une autre cartouche pyrotechnique et soulève ainsi le véhicule. Il peut alors changer la roue crevée.Thus if the lifting system is a car jack, the user in the event of a puncture can inflate the enclosure for the first time by placing a cartridge in the
La nouvelle roue étant mise en place et fixée, l'enceinte peut être dégonflée en enlevant par exemple la cartouche 10.The new wheel being put in place and fixed, the enclosure can be deflated by removing, for example, the
La figure 3a représente en coupe un exemple cartouche pyrotechnique. La cartouche 10 comporte une cavité 13 remplie de poudre pyrotechnique. Un embout 12 est fileté pour permettre une fixation dans le porte-cartouche 3 de l'enceinte gonflable. La cavité 13 peut communiquer par l'embout 12 avec l'intérieur de l'enceinte. Un joint 11 permet de parfaire l'étanchéité lors du montage de la cartouche dans le porte-cartouche 3. Enfin, la cartouche est munie d'électrodes 16 permettant la mise à feu de la poudre pyrotechnique. Ces électrodes sont connectées à des broches de connexion électriques 15, 15' du connecteur 14 de façon à pouvoir les connecter à une source d'alimentation électrique telle qu'une pile, la prise de l'allume-cigares du véhicule ou toute autre source électrique.FIG. 3a represents in section an example pyrotechnic cartridge. The
La figure 3b représente un porte-cartouche dans lequel peut être montée la cartouche de la figure 3a. Ce porte-cartouche comporte donc un trou fileté 31 (ou tout autre moyen de fixation) pour recevoir le filetage 12 de la cartouche. Un clapet anti-retour 32 permet au gaz de la cartouche de pénétrer dans l'enceinte mais empêche le gaz de ressortir de l'enceinte sauf à appuyer sur le clapet 32.Figure 3b shows a cartridge holder in which the cartridge of Figure 3a can be mounted. This cartridge holder therefore has a threaded hole 31 (or any other fixing means) for receiving the
La bague de montage 31 peut être réalisée de manière similaire au porte-cartouche de la figure 3b.The mounting
La figure 3c représente l'intérieur de l'enceinte 1, dans laquelle on a prévu des parois 20, 21, ... faisant office de chicanes à l'intérieur de l'enceinte. Ces parois ont pour rôle de répartir l'effet du gaz produit par la cartouche lors du gonflage.FIG. 3c represents the interior of the
Enfin, l'invention peut être destinée à servir de réserve de gaz comprimé. Par exemple, elle peut être appliquée à la commande d'un visseur/dévisseur pneumatique.Finally, the invention may be intended to serve as a reserve of compressed gas. For example, it can be applied to the control of a pneumatic screwdriver / deflector.
La figure 4 représente un exemple de réalisation d'un tel système. Il comporte une enceinte 1 munie d'un porte-cartouche 3 (ou d'une cartouche) et d'une bague de montage 31 à laquelle est fixé un conduit 32 reliée à un appareil de vissage/dévissage 6 à commande pneumatique.FIG. 4 represents an exemplary embodiment of such a system. It comprises an
A titre d'exemple, on précise que l'enceinte peut être réalisée à l'aide d'une toile en matériau du type connu commercialement sous le nom de Kevlar qui présente la caractéristique d'être souple, étanche mais très peu élastique.By way of example, it is specified that the enclosure can be produced using a canvas of material of the type known commercially under the name of Kevlar which has the characteristic of being flexible, waterproof but very inelastic.
Cette enceinte pourra être jetable ou non après utilisation. Par exemple, elle pourra se présenter sous la forme d'une baudruche parallélépipédique de dimensions extérieures I = 10 cm, L = 40 cm, hauteur = 1 à 2 cm en configuration de stockage.This enclosure may or may not be disposable after use. For example, it could be in the form of a rectangular bladder with external dimensions I = 10 cm, L = 40 cm, height = 1 to 2 cm in storage configuration.
