Description

L'invention qui se rapporte à un extincteur d'incendie concerne plus particulièrement un carénage protecteur et de sécurité destiné à s'adapter sur la tête de mise en oeuvre et de distribution montée au sommet du réservoir.The invention which relates to a fire extinguisher relates more particularly to a protective and safety fairing intended to be fitted on the implementation and distribution head mounted at the top of the tank.

Un carénage de sécurité comme défini dans le préambule de la revendiation 1 est connu du document DE-A-2931501.A safety fairing as defined in the preamble of claim 1 is known from document DE-A-2931501.

Les extincteurs utilisés jusqu'à présent sont comme on sait essentiellement constitués d'un réservoir muni à son sommet d'une ouverture sur laquelle est fixée une tête de distribution de l'agent extincteur. La tête qui est une pièce venant de fonderie ou d'usinage ou de moulage est pourvue d'un puits de traversée servant de support à un tube plongeur s'étendant jusqu'à la base du réservoir, puits qui le fait communiquer avec un flexible de raccordement à une soufflette équipée d'une canne pulvérisatrice ou d'une buse. La tête supporte également une cartouche fermée de gaz sous pression, soutenue à l'intérieur du réservoir, qui peut être mise en communication avec l'intérieur dudit réservoir après action d'un percuteur sur un opercule de bouchage de l'orifice de la cartouche. Le percuteur ainsi que les conduits de liaison sont logés dans la tête de distribution proprement dite maintenue en place sur le réservoir par un écrou de fixation ou autre système. Les extincteurs connus sont en outre équipés d'une poignée de préhension comme le montre le DE-A-29 31 501 et d'un levier presseur grâce auquel l'utilisateur peut en appuyant fortement, agir sur le percuteur de la tête de pulvérisation. cette opération n'est rendue possible que si il a au préalable tiré sur une goupille de verrouillage dudit levier presseur.The extinguishers used up to now are, as we know, essentially constituted by a reservoir provided at its top with an opening on which is fixed a head for dispensing the extinguishing agent. The head which is a part coming from foundry or machining or molding is provided with a through well serving as support for a dip tube extending up to the base of the tank, well which makes it communicate with a flexible for connection to a blower fitted with a spray cane or a nozzle. The head also supports a closed cartridge of pressurized gas, supported inside the reservoir, which can be placed in communication with the interior of said reservoir after the action of a striker on a sealing cap of the orifice of the cartridge. . The striker as well as the connecting conduits are housed in the actual dispensing head held in place on the tank by a fixing nut or other system. Known fire extinguishers are also equipped with a grip handle as shown in DE-A-29 31 501 and with a pressing lever by which the user can, by pressing strongly, act on the striker of the spray head. this operation is only made possible if he has previously pulled on a locking pin of said presser lever.

Il s'est avéré que la mise en oeuvre de ces extincteurs n'était pas toujours aisée, surtout quand l'utilisateur se trouve dans une situation de fébrilité en cas d'incendie. En effet l'arrachage de la goupille de sécurité qui traverse le levier presseur, exige; du fait de l'effet de cisaillement, une certaine force et ne se fait pas très facilement du fait que l'appareil peut être maintenu incliné et n'est pas à la main de l'utilisateur. Il faut ensuite exercer une pression également assez forte pour manoeuvrer le levier et percer l'opercule ce qui est plus difficile si le réservoir n'est pas en appui au sol. Cela représente au moins deux manipulations avant de pouvoir agir sur la soufflette de la canne pulvérisatrice ou de la buse. Les extincteurs connus présentent également un certain nombre d'autres inconvénients. Il y a notamment la fragilité de la tête de distribution non protégée contre les chocs, et qu'il conviendrait donc de coiffer par un capot. D'autre part le réservoir est muni, sur sa paroi extérieure d'étriers d'accrochage de l'appareil à un mur, de même que de pattes de fixation du flexible, toutes pièces qui sont donc rapportées sur le corps du réservoir, et particulièrement soumises à la corrosion, et qui augmentent sensiblement les risques de blessure pour l'utilisateur et le prix de revient de l'appareil.It turned out that the implementation of these extinguishers was not always easy, especially when the user is in a feverish situation in the event of fire. Indeed the tearing of the safety pin which crosses the presser lever, requires; due to the shearing effect, a certain force and is not very easy because the device can be kept tilted and is not in the hand of the user. You must then exert a pressure that is also strong enough to maneuver the lever and pierce the seal which is more difficult if the tank is not resting on the ground. This represents at least two manipulations before being able to act on the spray gun or nozzle nozzle. Known fire extinguishers also have a number of other drawbacks. There is in particular the fragility of the dispensing head which is not protected against shocks, and which should therefore be covered by a cover. Furthermore, the tank is provided, on its outer wall, with brackets for attaching the device to a wall, as well as lugs for fixing the hose, all parts which are therefore attached to the body of the tank, and particularly subject to corrosion, and which significantly increase the risk of injury to the user and the cost price of the device.

Dans le souci de chercher à réaliser un matériel plus simple à fabriquer et également plus maniable et plus rapide à utiliser, la Demanderesse a mis au point un nouveau carénage de sécurité adaptable à la tête de distribution qui évite les inconvénients précités.In order to seek to make equipment simpler to manufacture and also more manageable and faster to use, the Applicant has developed a new security fairing adaptable to the dispensing head which avoids the aforementioned drawbacks.

Un objet principal de la présente invention consiste donc en un carénage de sécurité se présentant comme une coque moulée en matière composite pour une tête de distribution fermant la partie supérieure d'un extincteur comportant un réservoir renfermant entre autre un tube plongeur et une cartouche de gaz sous pression pour l'évacuation de l'agent extincteur au travers de ladite tête vers une soufflette et comportant une poignée de maintien de l'extincteur et un anneau de commande, ledit carénage coiffant la tête de distribution à laquelle il est fixé, en la débordant de part et d'autre, une des parties débordantes constituant la poignée de maintien de l'extincteur, et l'autre partie débordante recevant un anneau de commande susceptible d'être arraché vers le haut par glissement hors du carénage, des moyens mécaniques de liaison étant localisés à l'intérieur du carénage pour transmettre le mouvement de l'anneau à un percuteur d'ouverture de la cartouche de gaz.A main object of the present invention therefore consists of a safety fairing in the form of a molded shell of composite material for a dispensing head closing the upper part of a fire extinguisher comprising a reservoir containing inter alia a dip tube and a gas cartridge under pressure for the evacuation of the extinguishing agent through said head towards a blower and comprising a handle for retaining the extinguisher and a control ring, said fairing covering the dispensing head to which it is fixed, by protruding from both sides, one of the protruding parts constituting the extinguisher holding handle, and the other protruding part receiving a control ring capable of being torn upwards by sliding out of the fairing, mechanical means link being located inside the fairing to transmit the movement of the ring to a striker opening the cartridge gas.

Selon une caractéristique particulière de l'invention, la partie débordante du carénage, du côté opposé à la poignée, est ouverte vers l'extérieur selon une lumière rectangulaire limitée par un profil faisant office de glissière pour l'anneau de commande.According to a particular characteristic of the invention, the projecting part of the fairing, on the side opposite to the handle, is open towards the outside in a rectangular light limited by a profile acting as a slide for the control ring.

Avantageusement l'anneau de commande est une pièce en matière plastique moulée dont la partie supérieure a la forme d'un anneau et dont la partie inférieure dispose latéralement de deux petites règlettes profilées destinées à coopérer avec le profil du carénage, ledit anneau portant une petite potence d'entraînement du mécanisme de liaison localisé à l'intérieur du carénage. L'anneau de commande a une couleur particulière qui renseigne sur le contenu du réservoir.Advantageously, the control ring is a molded plastic part, the upper part of which is in the form of a ring and the lower part of which has two small profiled strips laterally intended to cooperate with the profile of the fairing, said ring carrying a small linkage drive bracket located inside the fairing. The control ring has a special color which indicates the contents of the tank.

Les moyens mécaniques de liaison entre l'anneau et le percuteur sont constitués d'un levier articulé sur un maneton de la tête de distribution, et d'une tige du percuteur logé dans ladite tête de distribution, et ledit levier prenant appui d'un côté sur la potence de l'anneau de commande et d'un autre côté sur la tige du percuteur.The mechanical connection means between the ring and the striker consist of a lever articulated on a crank pin of the dispensing head, and of a striker rod housed in said dispensing head, and said lever bearing on a side on the stem of the control ring and on the other side on the striker rod.

D'autres caractéristiques particulières et avantages de l'invention apparaitront à la lecture de la description qui va suivre d'une forme de réalisation prise à titre d'exemple et faisant référence aux dessins annexés qui représentent :

  • Figure 1, une vue générale en coupe verticale d'un extincteur
  • Figure 2, une vue en coupe verticale et figure 3, une vue en plan et par au-dessous, du carénage
  • Figure 4 une vue schématique à plus grande échelle des glissières du carénage
  • Figure 5, une vue en perspective de l'anneau de commande.
  • Figure 6, une vue en coupe à plus grande échelle du carénage monté sur la tête de distribution.
Other particular characteristics and advantages of the invention will appear on reading the following description of an embodiment taken by way of example and referring to the appended drawings which represent:
  • Figure 1, a general view in vertical section of a fire extinguisher
  • Figure 2, a vertical sectional view and Figure 3, a plan view and from below, of the fairing
  • Figure 4 a schematic view on a larger scale of the fairing slides
  • Figure 5, a perspective view of the control ring.
  • Figure 6, a sectional view on a larger scale of the fairing mounted on the dispensing head.

On voit à la figure 1 un réservoir 20 d'extincteur sur l'orifice 2 duquel est montée une tête de distribution 3 obturant de façon étanche ledit orifice, à l'aide d'un écrou 4. La tête est pourvue d'un puits de traversée 5 servant de support à un tube 6 se développant sur toute la hauteur du réservoir à la partie inférieure duquel il débouche par un orifice 7. Le puits de traversée fait communiquer le tube plongeur avec un flexible 8 de raccordement à une soufflette 9 qui admet l'agent extincteur dans une canne pulvérisatrice 21. On notera que le flexible 8 vient en prolongement direct avec le tube plongeur par le puits de traversée.We see in Figure 1 a tank 20 of fire extinguisher on the orifice 2 which is mounted a distribution head 3 sealingly sealing said orifice, using a nut 4. The head is provided with a through-hole 5 serving as a support for a tube 6 developing over the entire height of the tank, at the bottom of which it opens out through an orifice 7. The through-hole communicates the dip tube with a flexible hose 8 for connection to a blower 9 which admits the extinguishing agent into a spray cane 21. It will be noted that the flexible hose 8 comes in direct extension with the dip tube through the through well.

La tête de distribution 3 qui est une pièce venant de fonderie ou d'usinage ou de moulage porte à sa partie supérieure deux ailes verticales 22 percées chacune d'un orifice 23. Les orifices en question servent à la fixation d'un carénage de sécurité désigné dans son ensemble par la référence 1, qui coiffe ladite tête et s'étend sensiblement sur tout le diamètre du réservoir comme on le verra plus loin. Du côté opposé aux ailes verticales, la tête est pourvue d'un manchon vertical 36 sur lequel vient se visser une cartouche 37 de gaz sous pression. Le manchon communique par un conduit non représenté avec l'intérieur du réservoir 20.The dispensing head 3 which is a part coming from foundry or machining or molding carries at its upper part two vertical wings 22 each pierced with an orifice 23. The orifices in question are used for fixing a safety fairing generally designated by the reference 1, which covers said head and extends substantially over the entire diameter of the reservoir as will be seen below. On the side opposite to the vertical wings, the head is provided with a vertical sleeve 36 onto which a cartridge 37 of pressurized gas is screwed. The sleeve communicates by a conduit, not shown, with the interior of the reservoir 20.

Le carénage 1 est décrit maintenant plus en détail en référence aux figures 2 et 3. Il a la forme générale d'une coque moulée en matière composite dont la face supérieure est sensiblement plane et dont la partie creuse inférieure est pourvue de nervures longitudinales 10 et transversales 11. On donne à cette coque une forme aussi esthétique que possible. Une extrémité du carénage est percée d'une ouverture délimitée par une bordure 13 formant poignée de préhension 12. Des moyens complémentaires de garnissage de la poignée sont prévus pour améliorer le confort de l'utilisateur. Au centre, à proximité de cette poignée le carénage est percé d'un orifice 14 autorisant le passage du puits de traversée 5. Du côté opposé il est ouvert vers l'extérieur selon une lumière rectangulaire 15 limitée par un profil 16 mieux visible sur la figure 4 faisant office de glissière pour un anneau de commande 24 qui sera décrit plus loin. La partie supérieure du carénage au dessus de la lumière 15 porte un oeilleton 19. L'extrémité inférieure de la coque du côté opposé à la poignée 12 forme un étrier 17, en avant de la lumière 15, étrier qui porte une patte verticale 18 pour l'accrochage de la soufflette On notera qu'au moins une partie du pourtour inférieure du carénage est conformée en forme d'une gouttière 41 ouverte vers le bas.The fairing 1 is now described in more detail with reference to FIGS. 2 and 3. It has the general shape of a molded shell of composite material, the upper face of which is substantially planar and the lower hollow part of which is provided with longitudinal ribs 10 and 11. This shell is given as aesthetic a shape as possible. One end of the fairing is pierced with an opening delimited by an edge 13 forming a grip handle 12. Additional means for lining the handle are provided to improve the comfort of the user. In the center, near this handle, the fairing is pierced with an orifice 14 allowing the passage of the through-hole 5. On the opposite side it is open towards the outside in a rectangular light 15 limited by a profile 16 better visible on the Figure 4 acting as a slide for a control ring 24 which will be described later. The upper part of the fairing above the light 15 carries an eyelet 19. The lower end of the shell on the side opposite to the handle 12 forms a stirrup 17, in front of the light 15, stirrup which carries a vertical tab 18 for attachment of the blow gun It will be noted that at least part of the lower periphery of the fairing is shaped in the form of a gutter 41 open downwards.

On a représenté à la figure 5 l'anneau de commande 24. Il est formé d'une pièce en matière plastique moulée dont la partie supérieure a la forme d'un anneau 25 et dont la partie inférieure 26 dispose latéralement de deux petites réglettes profilées 27 destinées à coopérer avec le profil 16 du carénage 1. A sa base, la partie inférieure de l'anneau porte une potence 28 orientée du même côté que les réglettes profilées. Enfin un petit orifice central 29 a été pratiqué au centre de l'anneau. L'anneau est équipé par exemple de petites pattes déformables supplémentaires en matière plastique qui interdiraient son réengagement dans les glissières après son arrachement,ou d'un système antiretour, ou encore il est muni d'une zone de faiblesse ou d'une partie cassante qui empêcherait sa remise en place.FIG. 5 shows the control ring 24. It is formed from a molded plastic part, the upper part of which has the shape of a ring 25 and the lower part 26 of which has two small profiled strips laterally. 27 intended to cooperate with the profile 16 of the fairing 1. At its base, the lower part of the ring carries a bracket 28 oriented on the same side as the profiled strips. Finally a small central hole 29 was made in the center of the ring. The ring is equipped for example with small additional deformable plastic legs which would prohibit its re-engagement in the slides after its tearing, or with a non-return system, or it is provided with a zone of weakness or a brittle part which would prevent it from being replaced.

En se reportant maintenant aux figures 1, 2 et 6, on voit le montage du carénage 1 sur la tête de distribution 3. Pour cela le carénage dispose de deux orifices latéraux 30, et une tige de maintien 31 traverse ces orifices et les orifices 23 de la tête pour solidariser ces deux pièces. On remarquera que le carénage déborde de chaque côté de la tête de distribution. La poignée de préhension 12 se trouve sur une des parties débordantes tandis que l'anneau de commande se trouve sur l'autre partie débordante du carénage.Referring now to Figures 1, 2 and 6, we see the mounting of the fairing 1 on the dispensing head 3. For this the fairing has two lateral orifices 30, and a retaining rod 31 passes through these orifices and the orifices 23 of the head to secure these two parts. Note that the fairing overflows on each side of the distribution head. The grip handle 12 is located on one of the projecting parts while the control ring is located on the other projecting part of the fairing.

A l'intérieur du carénage, dans le couloir délimité par les nervures longitudinales 10, s'étend un levier 32 articulé sur un maneton 33 solidaire de la tête 3. L'extrémité dudit levier, à proximité immédiate du maneton prend appui contre l'extrémité de la tige 34 d'un percuteur 35 logé à l'intérieur du manchon 36 ; le percuteur porte un joint torique 38 assurant l'étanchéïté dans le manchon, entre l'intérieur du réservoir et la tige 34. La pointe 39 du percuteur débouche à proximité de l'opercule de bouchage de la cartouche de gaz 37. le percuteur est rappelé par un ressort 42 en appui sur un épaulement de la tige 34 et sur une rondelle 43 de bouchage du manchon, d'appui de la bouteille et de maintien du ressort. L'extrémité opposée du levier 32 affleure la lumière 15 du carénage et vient en appui contre la potence 28 de l'anneau 24.Inside the fairing, in the corridor delimited by the longitudinal ribs 10, extends a lever 32 articulated on a crank pin 33 secured to the head 3. The end of said lever, in the immediate vicinity of the crank pin bears against the end of the rod 34 of a striker 35 housed inside the sleeve 36; the striker is wearing a O-ring 38 ensuring sealing in the sleeve, between the interior of the reservoir and the rod 34. The tip 39 of the striker opens near the sealing cap of the gas cartridge 37. the striker is returned by a spring 42 resting on a shoulder of the rod 34 and on a washer 43 for capping the sleeve, supporting the bottle and holding the spring. The opposite end of the lever 32 is flush with the lumen 15 of the fairing and bears against the bracket 28 of the ring 24.

Enfin un cache verrouillable 40 rapporté sous le carénage vient s'encliqueter sur l'étrier 17 et ferme le couloir contenant le levier 32. Il a essentiellement pour objet d'obturer la partie débordante du carénage et d'interdire ainsi l'accès au levier 32, pour éviter sa manoeuvre intempestive.Finally, a lockable cover 40 attached under the fairing snaps onto the stirrup 17 and closes the corridor containing the lever 32. Its main purpose is to close off the projecting part of the fairing and thus prohibit access to the lever 32, to avoid its untimely operation.

Dans ce cas et à l'aide de la gouttière 41, le carénage permet l'accrochage de l'extincteur à tout crochet mural, ce qui évite d'avoir à munir la paroi extérieure du réservoir d'étriers d'accrochage. Quand l'appareil est ainsi accroché, la soufflette 9 est suspendue à l'extrémité de l'étrier du carénage grâce à la patte verticale 18. La canne trouve ainsi sa place, verticalement le long du réservoir et il n'est donc pas nécessaire non plus de prévoir sur le réservoir un moyen d'accrochage quelconque.In this case and using the gutter 41, the fairing allows the extinguisher to be hooked to any wall hook, which avoids having to provide the outer wall of the reservoir with hooking stirrups. When the device is thus hooked, the blowgun 9 is suspended from the end of the fairing stirrup by means of the vertical tab 18. The rod thus finds its place, vertically along the tank and it is therefore not necessary no longer to provide any means of attachment to the tank.

Le carénage 1 étant solidement fixé à la tête de pulvérisation 3 c'est-à-dire au réservoir, l'utilisateur peut aisément saisir l'appareil à l'aide de la poignée 12. Sans poser l'appareil au sol, et en un seul geste instinctif et naturel il saura tirer vers le haut l'anneau de commande 24 qui sectionne un fil de plombage léger 44 traversant l'oeilleton 19 et l'orifice 29. La position particulière de l'anneau de commande 24 du côté opposé à la poignée rend très aisée et naturelle cette manoeuvre d'arrachement . Au cours de ce mouvement sont assurées en un seul geste deux opérations. D'une part un déverrouillage de l'anneau de commande. D'autre part la mise en pression du réservoir par perforation de l'opercule de bouchage de la cartouche 37. En effet, lors du déplacement vers le haut de l'anneau 24, dont les profilés 27 coulissent dans les glissières 16, la potence 28 fait basculer le levier 32 qui enfoncera la tige 34 du percuteur 35 à l'encontre de la force du ressort 42 et fait agir la pointe 33. La démultiplication introduite par le levier 32 fait que l'utilisateur, dans le même geste n'a pas à exercer un effort important pour arracher l'anneau et mettre le réservoir en pression, à l'inverse des systèmes habituels connus. La résistance opposée par le ressort est négligeable, ce dernier ayant seulement pour rôle de maintenir le percuteur en position haute, quand l'extincteur est au repos. On notera que l'anneau arraché est complètement sorti des glissières et qu'il ne peut être remis en place du fait notamment du système antiretour évoqué précédemment. L'agent extincteur peut alors être pulvérisé par action de l'utilisateur sur la soufflette 9.The fairing 1 being securely attached to the spray head 3, that is to say to the reservoir, the user can easily grasp the device using the handle 12. Without placing the device on the ground, and in a single instinctive and natural gesture he will be able to pull up the control ring 24 which cuts a light sealing wire 44 passing through the eyelet 19 and the orifice 29. The particular position of the control ring 24 on the opposite side with the handle makes this tear-off operation very easy and natural. During this movement are assured in one gesture two operations. On the one hand, an unlocking of the control ring. On the other hand the pressurization of the reservoir by perforation of the sealing cap of the cartridge 37. In fact, during the upward movement of the ring 24, the profiles 27 of which slide in the slides 16, the bracket 28 causes the lever 32 to tilt which will depress the rod 34 of the striker 35 against the force of the spring 42 and causes the tip 33 to act. The reduction introduced by the lever 32 means that the user, in the same gesture does not does not have to exert a significant effort to tear off the ring and put the tank under pressure, unlike the usual known systems. The resistance opposed by the spring is negligible, the latter only having the role of keeping the striker in the high position, when the extinguisher is at rest. Note that the torn ring is completely out of the slides and it can not be replaced due in particular to the non-return system mentioned above. The extinguishing agent can then be sprayed by action of the user on the blow gun 9.

Le carénage 1 facilite donc grandement l'accrochage et la manipulation de l'extincteur. En outre il protège complètement des chocs l'ensemble fonctionnel et la tête de distribution. Il est avantageusement réalisé en matériau composite moulé, sans parties saillantes ni angles vifs, et puisqu'il intègre la poignée de portage et le support du flexible, il évite la fabrication et le montage de ces pièces habituelles. De son côté, l'anneau de commande 24 également en matière plastique, par exemple en polyamide qui ne craint ni l'oxydation, ni le grippage, ni les déformations, est choisi dans une couleur qui tranche avec celle du carénage pour être repérable facilement. On peut avantageusement donner à l'anneau utilisé une couleur qui renseigne sur le contenu du réservoir, et matérialise la nature de l'agent extincteur.The fairing 1 therefore greatly facilitates the attachment and handling of the fire extinguisher. In addition, it completely protects the functional unit and the dispensing head from impact. It is advantageously made of molded composite material, without projecting parts or sharp corners, and since it incorporates the carrying handle and the support of the hose, it avoids the manufacture and assembly of these usual parts. For its part, the control ring 24 also made of plastic, for example polyamide which fears neither oxidation, seizure or deformation, is chosen in a color which contrasts with that of the fairing to be easily identifiable . It is advantageous to give the ring used a color which provides information on the content of the tank, and materializes the nature of the extinguishing agent.
