Description

La présente invention a trait à un système de fixation destiné à permettre la solidarisation d'un appareil à gaz et d'une cartouche de fluide sous pression. Elle concerne plus précisément, mais non exclusivement, un système de fixation avec une cartouche du type "aérosol" contenant un gaz combustible liquéfié, par exemple du butane. Pour mémoire, on rappelle que ces cartouches comprennent en général un corps cylindrique avec dôme supérieur convexe, une coupelle concave sertie sur le dôme supérieur, une valve de prélèvement et/ou remplissage logée au centre de la coupelle concave. Les deux bords sertis appartenant respectivement au dôme convexe et à la coupelle concave déterminent un rebord annulaire à l'intérieur et sous lequel peuvent venir s'encliqueter les organes d'accrochage du système de fixation mentionné précédemment.The present invention relates to a fastening system intended to allow the fastening of a gas appliance and a cartridge of pressurized fluid. It relates more precisely, but not exclusively, to a fixing system with a cartridge of the "aerosol" type containing a liquefied combustible gas, for example butane. As a reminder, it should be recalled that these cartridges generally comprise a cylindrical body with a convex upper dome, a concave cup crimped onto the upper dome, a sampling and / or filling valve housed in the center of the concave cup. The two crimped edges belonging respectively to the convex dome and to the concave cup determine an annular rim inside and under which the fastening members of the fixing system mentioned above can be snapped.

Pour certaines applications, notamment soudage, éclairage et cuisson, il est connu de fixer des dispositifs correspondants sur des cartouches aérosol contenant du butane liquéfié, l'ensemble cartouche-dispositif constituant alors un appareil portatif pouvant être aisément maintenu en main par le corps cylindrique de la cartouche.For certain applications, in particular welding, lighting and cooking, it is known to fix corresponding devices on aerosol cartridges containing liquefied butane, the cartridge-device assembly then constituting a portable device which can be easily held in hand by the cylindrical body of the cartridge.

Deux problèmes apparemment contradictoires doivent être résolus pour des appareils portatifs tels qu'évoqués au paragraphe précédent. Tout d'abord, le dispositif fixé sur la cartouche doit faire corps avec cette dernière, ce qui signifie que le système de fixation mis en oeuvre doit apporter une solidarisation rigide du dispositif sur la cartouche, de manière à éviter tout mouvement relatif de ces deux éléments, susceptible d'engendrer une fuite de gaz combustible. Par ailleurs, ces appareils pouvant tomber accidentellement, il est primordial que l'effort nécessaire pour désolidariser le dispositif de la cartouche soit inférieur à celui indispensable pour dessertir la coupelle du dôme supérie.r de la cartouche, de manière que ces chutes entraînent une sépamtion du dispositif à partir de la cartouche, et non une fuite de jaz combustible à la jonction coupelle-dôme.Two apparently contradictory problems must be resolved for portable devices as mentioned in the previous paragraph. First, the device attached to the cartridge must be re body with the latter, which means that the fixing system used must provide a rigid connection of the device on the cartridge, so as to avoid any relative movement of these two elements, likely to cause a leakage of combustible gas. Furthermore, since these devices may fall accidentally, it is essential that the effort required to separate the device from the cartridge is less than that necessary to serve the cup of the upper dome of the cartridge, so that these drops cause separation. of the device from the cartridge, not a leakage of combustible jaz at the cup-dome junction.

Dans ce contexte, il faut donc trouver un système de fixation qui permette de "doser" convenablement l'effort de solidarisation du dispositif sur la cartouche entre les deux limites évoquées précédemment, et ce en assurant une fonction supplémentaire non rencontrée pour les principaux systèmes équivalents de l'art anté- rieur, à savoir un positionnement rigide du dispositif sur la cartouche.In this context, it is therefore necessary to find a fixing system which makes it possible to "properly dose" the effort of securing the device on the cartridge between the two limits mentioned above, and this while ensuring an additional function not encountered for the main equivalent systems. of the prior art, namely a rigid positioning of the device on the cartridge.

A cette fin, selon la présente invention, l'on a trouvé qu'un système de fixation conforme à la définition générale suivante convenait bien à la solution du problème technique précédent.To this end, according to the present invention, it has been found that a fixing system in accordance with the following general definition is well suited to the solution of the preceding technical problem.

Un système de fixation selon l'invention, comprend :

  • - un noyau central solidaire de l'appareil, comportait des moyens de prélèvement de fluide destinés à coopérer avec la valve de la cartouche.
  • - une pièce annulaire entourant le noyau central, iportant sur son pourtour plusieurs organes d'accrochage encliquetables à l'intérieur et sous le bourrelet annulaire de la cartouche ; chaque organe d'accrochage comporte, d'une part une griffe d'accrochage mobile vers la paroi en creux du bourrelet annulaire de la cartouche, et d'autre part un moyen de blocage positif de ladite griffe à l'intérieur et sous le bourrelet précité, actionné par le noyau central, lors du vissage (défini ci-après) ce dernier à l'intérieur de la pièce annulaire
  • - des moyens de déplacement axial du noyau central par rap- port et à l'intérieur de la pièce annulaire, consistant en un taraudage à l'intérieur de ladite pièce, et en un filetage à l'extérieur du noyau central, coopérant avec le taraudage.
A fixing system according to the invention comprises:
  • - A central core integral with the device, included means for withdrawing fluid intended to cooperate with the valve of the cartridge.
  • - an annular part surrounding the central core, iportorting around its periphery several snap-fastening members inside and under the annular bead of the cartridge; each hooking member comprises, on the one hand a hooking claw movable towards the hollow wall of the annular bead of the cartridge, and on the other hand a means of positive blocking of said claw inside and under the bead mentioned above, actuated by the central core, during screwing (defined below), the latter inside the annular part
  • means of axial displacement of the central core with respect to port and inside the annular part, consisting of a thread inside said part, and a thread outside the central core, cooperating with the thread.

Le moyen de blocage de chaque organe d'accrochage comprend préférablement un élément de poussée sur lequel la partie inférieure du noyau central vient en appui.The locking means of each hooking member preferably comprises a pushing element on which the lower part of the central core bears.

Par moyen de blocage positif, on entend un moyen distinct des autres organes du système de fixation, permettant d'accomplir de manière réversible une fonction nouvelle, à savoir amener la griffe de chaque organe d'accrochage en pression contre la paroi interne du bourrelet annulaire de la cartouche.By positive locking means is meant a means distinct from the other members of the fixing system, making it possible to reversibly perform a new function, namely bringing the claw of each hooking member under pressure against the internal wall of the annular bead cartridge.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.

On a représenté en fig. 1 une cartouche 1 de fluide sous pression tel que du butane liquéfié, affectant la forme d'un réservoir pour aérosol, ainsi qu'un système de fixation suivant l'invention destiné à permettre d'associer un appareil à gaz 2 à ladite cartouche.There is shown in fig. 1 a cartridge 1 of pressurized fluid such as liquefied butane, affecting the shape of an aerosol container, as well as a fixing system according to the invention intended to allow a gas appliance 2 to be associated with said cartridge.

A la manière connue la cartouche 1 comporte un corps cylindrique la avec dôme supérieur convexe 1b ; une coupelle concave 1c est sertie sur le dôme 1b et forme avec lui un bourrelet annulaire lc. Une valve de prélèvement la est disposée au centre de la coupelle lc.In the known manner the cartridge 1 comprises a cylindrical body la with a convex upper dome 1b; a concave cup 1c is set on the dome 1b and forms with it an annular bead lc. A sampling valve 1a is arranged in the center of the cup 1c.

L'appareil 2 est pourvu d'un noyau central 4 fileté extérieurement comportant dans son centre un dispositif connu à prélèvement 5 destiné à coopérer avec la valve le de la cartouche 1.The device 2 is provided with an externally threaded central core 4 comprising in its center a known sampling device 5 intended to cooperate with the valve 1c of the cartridge 1.

Le système suivant l'invention est encore composé d'une pièce annulaire 3 réalisée sous la forme d'une cloche cylindrique 6 surmontée d'une cheminée tubulaire et centrale Cette dernière comporte un taraudage coopérant avec le filetage du noyau 4.The system according to the invention is also composed of an annular part 3 produced in the form of a cylindrical bell 6 surmounted by a tubular and central chimney The latter comprises a thread cooperating with the thread of the core 4.

Comme montré en fig. 2, la jonction de la cheminée et de la face supérieure 6a de la cloche 6 est pourvue de quatre ouvertures 2 disposées à 90° les unes des autres et qui s'étendent partie dans la paroi supérieure de la cloche, partie dans la cheminée 7. Chacune des ouvertures permet le passage d'une griffe 9 (ou organe d'accrochage) réalisée sous la forme d'une lame d'acier à ressort convenablement coudée et qui est rivée à une extrémité sur la face supérieure 6a de la cloche 6. Chaque griffe 9 comprend une partie rectiligne 9a solidarisée à la face 6a au moyen d'un rivet 10 et qui se prolonge par une partie 9b tournée vers le bas traversant l'ouverture 8 correspondante, suivie d'un talon d'accrochage 9c cambré vers l'extérieur auquel fait suite une patte 9d (formant moyen de blocage) orientée vers le centre et obliquement par rapport à l'horizontale. Cette patte 9d, qui s'étend au moins partiellement sous la partie inférieure du noyau 4, constitue un élément de poussÉe de la griffe correspondante. L'ensemble des talons 9c des griffes 9 est en gros situé sur une circonférence de diamètre légèrement supérieur à celui intérieur du bourrelet 1d. Ainsi lorsque le noyau central 4 est légèrement vissé dans l'alésage taraudé de la cheminée 7 il est possible d'encliqueter les griffes à l'intérieur et sous le bourrelet la (fig. 3), la face inférieure 6b de la cloche 6 venant en appui contre le dessus du bourrelet précité.As shown in fig. 2, the junction of the chimney and the upper face 6a of the bell 6 is provided with four openings 2 arranged at 90 ° from one another and which extend partly in the upper wall of the bell, part in the chimney 7 Each of the openings allows the passage of a claw 9 (or hooking member) produced in the form of a spring steel blade suitably bent and which is riveted at one end on the upper face 6a of the bell 6 Each claw 9 comprises a rectilinear part 9a secured to the face 6a by means of a rivet 10 and which is extended by a part 9b facing downwards passing through the corresponding opening 8, followed by a hooked heel 9c outwardly followed by a tab 9d (forming a locking means) oriented towards the center and obliquely to the horizontal. This tab 9d, which extends at least partially under the lower part of the core 4, constitutes a pushing element of the corresponding claw. The set of heels 9c of the claws 9 is roughly situated on a circumference of diameter slightly greater than that inside of the bead 1d. Thus when the central core 4 is slightly screwed into the threaded bore of the chimney 7 it is possible to snap the claws inside and under the bead la (fig. 3), the lower face 6b of the bell 6 coming resting against the top of the aforementioned bead.

Lorsque l'utilisateur maintient la pièce annulaire 3 angulairement fixe tandis quil fait tourner l'appareil 2, son noyau central 4 se déplace ax.element vers le bas par rapport et à l'intérieur de la cloche 6, par vissage dans l'alésage taraudé de la cheminée 7. L'extrémité libre ou partie inférieure du noyau 4 vient alors actionner le moye de blocage de chaque organe d'accrochage 9, et plus précisément gir contre les pattes ou éléments de poussée 9d des griffes 9 ervue de mouvoir élastiquement les talons 9c de manière centrifug vers la paroi en creux du bourrelet 1d ; les talons 9c viennent ,insi se verrouiller positivement sous le bourrelet Id de la cartuche 1. A ce moment le dispositif 5 du noyau 4 agit sur la val le de la cartouche 1 pour l'ouvrir afin que le gaz que contient a cartouche puisse s'écouler par un canal 5a en direction de 1 partie active de l'appareil 2 qui comprend généralement un robinet d'arrêt. On assiste donc à une solidarisation rigide de l'appareil 2 par rapport à la cartouche 1 par blocage positif des griffes 9 sous le bourrelet la venant s'ajouter à l'encliquetage élastique des mêmes griffes. En faisant varier le nombre de griffes 9, il est possible de modifier l'effort nécessaire à la désolidarisation de l'appareil et de la cartouche, donc d'adapter cet effort par rapport à celui nécessaire au dessertissage de la cartouche.When the user keeps the annular part 3 angularly fixed while he rotates the device 2, its central core 4 moves ax.element down relative to and inside the bell 6, by screwing in the bore threaded from the chimney 7. The free end or lower part of the core 4 then actuates the locking hub of each fastening member 9, and more precisely lies against the legs or pushing elements 9d of the claws 9 ervue to move elastically the heels 9c centrifuged towards the hollow wall of the bead 1d; heels 9c come, insi lock positively under the bead Id of the cartridge 1. At this time the device 5 of the core 4 acts on the valle of the cartridge 1 to open it so that the gas that contains a cartridge can s '' flow through a channel 5a towards 1 active part of the device 2 which com usually takes a stopcock. There is therefore a rigid attachment of the device 2 relative to the cartridge 1 by positive locking of the claws 9 under the bead adding it to the elastic snap-fastening of the same claws. By varying the number of claws 9, it is possible to modify the force necessary for the separation of the device and the cartridge, and therefore to adapt this force compared to that necessary for the unplugging of the cartridge.

En vue d'éviter la perte de la pièce annulaire 3 par dévissage intempestif à partir du noyau 4 de l'appareil 2 lorsque ce dernier n'est pas associé à une cartouche, on effectue dans le noyau une gorge 4a située du côté du noyau associé à l'appareil 2 et l'on pratique dans la cheminée tubulaire 7 de la pièce annulaire 3 au moins deux fentes 7a, 7b orientés parallèlement à l'extrémité supérieure de ladite cheminée. Après vissage du noyau 4 dans l'alésage taraudé de la cheminée 7 on peut déformer le haut de cette cheminée au-dessus des fentes 7a, 7b de manière à former deux saillies 7c, 7d (fig. 6 et 7) tournées vers l'intérieur et dont la distance est inférieure au diamètre extérieur du noyau tout en étant légèrement supérieure à celui du fond de la gorge 4a. La hauteur de celle-ci est, bien entendu, prévue de manière que les saillies 7c, 7d n'empêchent pas l'extrémité libre du noyau 4 d'agir sur les pattes 9d des griffes 9.In order to avoid the loss of the annular part 3 by untimely unscrewing from the core 4 of the device 2 when the latter is not associated with a cartridge, a groove 4a is made located on the side of the core associated with the device 2 and practiced in the tubular chimney 7 of the annular part 3 at least two slots 7a, 7b oriented parallel to the upper end of said chimney. After screwing the core 4 into the threaded bore of the chimney 7, the top of this chimney can be deformed above the slots 7a, 7b so as to form two projections 7c, 7d (fig. 6 and 7) facing towards interior and whose distance is less than the outer diameter of the core while being slightly greater than that of the bottom of the groove 4a. The height of the latter is, of course, provided so that the projections 7c, 7d do not prevent the free end of the core 4 from acting on the legs 9d of the claws 9.

On a représenté en fig. 8 une variante d'exécution des organes d'accrochage qui se trouvent chacun réalisé sous la forme d'un élément pivotant comportant au moins deux dents. Dans la forme avantageuse d'exécution de fig. 8 la pièce annulaire 3 ne comporte plus les ouvertures 8, mais la cheminée 7 se prolonge vers le bas par une jupe interne 11 qui s'étend concentriquement à la périphérie de la cloche 6. La jupe 11 qui comporte une certaine épaisseur est pourvue d'au moins deux entailles parallèles lla, Ilb diamétralement opposées à travers lesquelles s'étend un axe, réalisé sous la forme d'une goupille cylindrique 12 fixée à la jupe 11 par tous moyens non représentés, par exemple par rivetage, et autour de laquelle est montée à rotation libre une roulette 13 formant l'élément pivotant précité, comportant quatre dents 14 régulièrement réparties sur sa périphérie.There is shown in fig. 8 an alternative embodiment of the fastening members which are each produced in the form of a pivoting element comprising at least two teeth. In the advantageous embodiment of FIG. 8 the annular part 3 no longer has the openings 8, but the chimney 7 is extended downwards by an internal skirt 11 which extends concentrically to the periphery of the bell 6. The skirt 11 which has a certain thickness is provided with '' at least two parallel notches 11a, Ilb diametrically opposite through which extends an axis, produced in the form of a cylindrical pin 12 fixed to the skirt 11 by any means not shown, for example by riveting, and around which is mounted with free rotation a roller 13 forming the aforementioned pivoting element, comprising four teeth 14 regularly distributed around its periphery.

Lorsqu'on présente le dispositif suivant fig. 8 et 9 en face du bourrelet ld de la cartouche 1 celui-ci coopère avec une des dents des roulettes 13 ; lorsqu'on poursuit le mouvement de déplacement de l'ensemble 2-3 en direction de la cartouche, on provoque la rotation des roulettes 13. L'une des dents de chacune de ces roulettes, formant alors élément d'accrochage, s'encliquette donc sous le bourrelet ld tandis que sa dent diamétralement opposée, formant alors élément de poussée, vient se disposer en face de l'extrémité inférieure du noyau 4.En fin de vissage de ce dernier par rapport à la cheminée 7, on comprend aisément qu'on provoque le blocage positif de la dent d'accrochage sous le bourrelet la par action de l'extrémité du noyau 4 contre la dent de poussée.When we present the following device fig. 8 and 9 in front of the bead ld of the cartridge 1 the latter cooperates with one of the teeth of the rollers 13; when the movement of movement of the assembly 2-3 continues in the direction of the cartridge, the rollers 13 are caused to rotate. One of the teeth of each of these rollers, then forming a hooking element, engages therefore under the bead ld while its diametrically opposite tooth, then forming a pushing element, comes to be arranged opposite the lower end of the core 4.At the end of screwing the latter relative to the chimney 7, it is easily understood that 'causes positive locking of the hooking tooth under the bead by the action of the end of the core 4 against the pushing tooth.

On notera que dans cette forme d'exécution le moyen de rendre indémontable la pièce annulaire 3 du noyau 4 consiste en une goupille 15 rendue solidaire de la cheminée 7 et qui est engagée transversalement dans celle-ci de manière qu'elle se trouve dans la gorge 4a du noyau.It will be noted that in this embodiment the means of making the annular part 3 of the core 4 non-removable consists of a pin 15 made integral with the chimney 7 and which is engaged transversely in the latter so that it is in the throat 4a of the nucleus.

Dans la variante de fig. 10 la jupe 11 est pourvue d'une gorge intérieure llc dans laquelle est engagé un jonc circulaire élastique 16 qui constitue l'axe d'articulation des roulettes 13.In the variant of fig. 10 the skirt 11 is provided with an internal groove 11c in which is engaged an elastic circular rod 16 which constitutes the axis of articulation of the rollers 13.

Comme montré en fig. 11 on pourrait ménager dans la jupe 11 une gorge extérieure lld dans laquelle serait engagé le jonc 16.As shown in fig. 11 one could arrange in the skirt 11 an outer groove lld in which the rod 16 would be engaged.

Selon fig. 8 à 11, il est possible de modifier l'effort de désolidarisation de l'appareil et de la cartouche, en fonction du nombre de roulettes 13, et/ou de la forme et/ou de l'emplacement de l'axe d'articulation desdites roulettes.According to fig. 8 to 11, it is possible to modify the separation force of the device and the cartridge, depending on the number of rollers 13, and / or the shape and / or the location of the axis of articulation of said rollers.

On a représenté en fig. 12 un mode d'exécution préféré du système de fixation suivant l'invention. Le noyau central 4 comporte à sa partie inférieure une portée 4b de diamètre inférieur à celui à fond de filet de sa partie filetée et qui se termine par un chanfrein 4c. La portée 4b diminue donc de manière sensible la longueur filetée du noyau 4.There is shown in fig. 12 a preferred embodiment of the fixing system according to the invention. The central core 4 has at its lower part a bearing 4b of diameter smaller than that at the bottom of the thread of its threaded part and which ends in a chamfer 4c. The range 4b therefore significantly reduces the threaded length of the core 4.

La pièce annulaire 3 est réalisée sous la forme d'un organe moulé en une matière plastique appropriée. Elle comprend un écrou cylindrique 17 se prolongeant vers le bas par une douille 18 comportant quatre fentes radiales 19 de sorte que cette douille est constituée par quatre mors élastiques indépendants 20 reliés à l'écrou 17. La douille 18 est pourvue d'un alésage conique 21 ouvert vers le haut faisant suite à la partie taraudée de l'écrou 17 et qui se prolonge en direction du bas par un second alésage tronconique 22 à conicité plus importante ; ainsi se trouve déterminé sur chaque mors un élément de poussée 23 sous la forme d'une surface oblique tournée vers l'intérieur. La périphérie extérieure de la douille 18, donc aussi chacun des mors 20, comporte une saillie 24 formant talon d'accrochage surmonté d'une collerette ou bec 25. Enfin l'écrou 17 est pourvu de deux ailettes 17a, 17b destinées à faciliter son actionnement.The annular part 3 is produced in the form of a member molded from a suitable plastic material. It comprises a cylindrical nut 17 extending downwards by a socket 18 comprising four radial slots 19 so that this socket is constituted by four independent elastic jaws 20 connected to the nut 17. The socket 18 is provided with a conical bore 21 open upwards following the tapped part of the nut 17 and which extends towards the bottom by a second frustoconical bore 22 with greater conicity; thus is determined on each jaw a pushing element 23 in the form of an oblique surface facing inward. The outer periphery of the sleeve 18, therefore also each of the jaws 20, has a projection 24 forming a hooking heel surmounted by a flange or spout 25. Finally, the nut 17 is provided with two fins 17a, 17b intended to facilitate its actuation.

La pièce annulaire 3 étant vissée partiellement ou non sur le filetage du noyau central 4, on peut engager élastiquement les talons 24 sous la partie intérieure du bourrelet Id de la cartouche 1. Si l'on immobilise angulairement la prèce annulaire 3 au moyen des ailettes 17a, 17b et qu'on visse le noyau 4 dans ladite pièce, le chanfrein 4c du noyau vient à la fin :u vissage porter contre l'alésage tronconique 22, ce qui entraîre un mouvement des mors 20 de manière centrifuge si bien que leurs talons 24 viennent se bloquer sous le bourrelet ld de la cart:uche 1, de la même façon que le talon 9c des griffes 9 décrites :n référence à fig. 3.The annular part 3 being partially or not screwed onto the thread of the central core 4, the heels 24 can be engaged elastically under the inner part of the bead Id of the cartridge 1. If the annular part 3 is angularly immobilized by means of the fins 17a, 17b and that the core 4 is screwed into said part, the chamfer 4c of the core comes at the end: u screwing bear against the frustoconical bore 22, which causes the jaws 20 to move in a centrifugal manner so that their heels 24 come to hang under the bead ld of the cart: uche 1, in the same way as the heel 9c of the claws 9 described: n reference to fig. 3.

Là encore, conformément à fig. 12 et 13, il est possible de modifier l'effort de désolidarisation cartouche-appareil, en limitant la résistance mécanique des mors élastiques 20, la séparabilité de l'organe moulé 3 le rendant facilement remplaçable.Again, according to fig. 12 and 13, it is possible to modify the cartridge-device separation force, by limiting the mechanical resistance of the elastic jaws 20, the separability of the molded member 3 making it easily replaceable.

Dans toutes les variantes décrites ;lus haut, lorsque le noyau est dévissé par rapport à la pièce nnulaire, les organes d'accrochage sont libérés de l'action de blocage positif si bien qu'on peut aisément dégager élastiquement le système de fixation de la cartouche. Dans le cas illustré en fig. 12 et 13 on choisira de réaliser la pièce annulaire 3 en une matière plastique suffisamment rigide et élastique. A titre d'exemple non limitatif on peut citer le polypropylène comme matière susceptible de convenir particulièrement bien à sa réalisation.In all of the variants described; read above, when the core is unscrewed relative to the ring piece, the hooking members are released from the positive locking action so that the fixing system can easily be released cartridge. In the case illustrated in fig. 12 and 13 we will choose to make the annular part 3 in a sufficiently rigid and elastic plastic material. By way of nonlimiting example, mention may be made of polypropylene as a material capable of being particularly suitable for its production.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
