Description

Domaine techniqueTechnical area

L'invention a trait au domaine des bouteilles de gaz, notamment des bouteilles de gaz du type butane et propane. Plus particulièrement, l'invention a trait aux colliers de préhension de telles bouteilles et/ou de protection des robinets montés sur ces bouteilles.The invention relates to the field of gas cylinders, in particular gas cylinders of the butane and propane type. More particularly, the invention relates to grippers of such bottles and / or protection valves mounted on these bottles.

Technique antérieurePrior art

Le document de brevet US 5,004,117 A divulgue un collier de préhension et de protection pour bouteille de gaz, notamment pour gaz industriel. Le dispositif est en métal et présente une forme annulaire généralement cylindrique et évasée vers le haut. Il comprend un orifice avec un filetage femelle à sa base, le filetage étant destiné à être vissé sur un filetage mâle sur le col de la bouteille. La portion filetée comprend des moyens de serrage du filetage de manière permettre un blocage en rotation. Il comprend également dans sa partie cylindrique évasée une ouverture radiale destinée à permettre un accès au robinet vissé sur la bouteille. La portion de matière de la partie cylindrique évasée située au-dessus de l'ouverture sert de poignée de préhension. Le volume intérieur de ce collier de protection est réduit. De plus, il ne comporte qu'une seule poignée de préhension. La poignée de préhension est par ailleurs disposée au droit de la sortie du robinet. L'espace disponible au niveau de la poignée peut ainsi se voir réduit lorsqu'un détendeur volumineux est raccordé au robinet et traverse l'ouverture radiale.The patent document US 5,004,117 A discloses a gripping and protection collar for a gas cylinder, in particular for industrial gas. The device is metal and has a generally cylindrical annular shape and flared upwards. It comprises an orifice with a female thread at its base, the thread being intended to be screwed onto a male thread on the neck of the bottle. The threaded portion comprises means for clamping the thread so as to allow locking in rotation. It also comprises in its flared cylindrical portion a radial opening for allowing access to the valve screwed on the bottle. The portion of material of the flared cylindrical portion located above the opening serves as a gripping handle. The interior volume of this protective collar is reduced. In addition, it has only one handle. The handle is also arranged at the right of the tap outlet. The space available at the handle can thus be reduced when a large expansion valve is connected to the valve and passes through the radial opening.

Le document de brevet US 3,776,412 A divulgue un collier de préhension et de protection pour bouteille de gaz de construction similaire à celle du document précédent. La fixation du collier à la bouteille est toutefois réalisée au moyen d'un alésage sur le collier coopérant avec une portée cylindrique sur le col de la bouteille. Un circlips est logé dans une gorge sur la portée cylindrique, de manière à retenir le collier en place sur ladite portée. Le collier est conçu pour pouvoir tourner librement sur la bouteille de manière à pouvoir ajuster à son propre gré sa position angulaire. En cas de blocage inopiné dans une position angulaire non désirée, des mesures particulières, tels que des efforts importants ou encore un démontage, doivent alors être mis en oeuvre afin de pouvoir exploiter la bouteille de gaz.The patent document US 3,776,412A discloses a gripping and protection collar for a construction gas cylinder similar to that of the preceding document. Fixing the collar to the bottle, however, is achieved by means of a bore on the collar cooperating with a cylindrical surface on the neck of the bottle. A circlip is housed in a groove on the cylindrical bearing, so as to retain the collar in place on said scope. The collar is designed to rotate freely on the bottle so that it can adjust its angular position at will. In case of unexpected blocking in an undesired angular position, special measures, such as major efforts or disassembly, must then be implemented in order to operate the gas cylinder.

Le document de brevet US 4,332,331 A divulgue également un collier de préhension et de protection pour bouteille de gaz, de construction similaire à celles des documents précédents. La position angulaire du collier est réglable et peut être arrêtée grâce à un contre écrou vissé sur un filetage mâle sur le col de la bouteille. Ce contre écrou exerce alors un effort sur le collier, le pressant contre la bouteille.The patent document US 4,332,331 A also discloses a gripping collar and protection for a gas cylinder, of similar construction to those of the previous documents. The angular position of the collar is adjustable and can be stopped by a counter nut screwed on a male thread on the neck of the bottle. This nut then exerts a force on the collar, pressing it against the bottle.

Les moyens de fixation des colliers décrits ci-avant sont particulièrement robustes mais requièrent du col de bouteille qu'il présente un filetage ou une portée cylindrique d'une certaine taille. Ce type de collier n'est donc pas applicable à toutes les bouteilles, notamment certaines bouteilles de gaz combustible tels que du butane ou propane dont le col est de diamètre réduit. De plus les moyens de fixation avec filetage des colliers décrits ci-avant requièrent une construction lourde et coûteuse. Le montage et démontage des colliers décrits ci-avant peut également s'avérer long et parfois difficile. En effet, le collier et le col de la bouteille étant métalliques, ils sont susceptibles de s'oxyder et de gripper l'un avec l'autre. De plus, les systèmes à serrage requièrent de manipuler des vis et/ou écrou sur un certain nombre de tours. Ces vis et écrou de serrage sont également susceptibles de s'oxyder et de gripper. Pour le cas où le collier comprend un alésage disposé sur une portée cylindrique, l'ajustement est tel que pareillement l'oxydation et/ou l'accumulation de poussière et de particules est susceptible de rendre difficile le démontage d'un collier et/ou le remontage d'un autre collier. Or dans le cadre de la remise état de bouteille de gaz, notamment les bouteilles de gaz combustible tel que le propane et le butane, il est courant que les colliers doivent être remplacés.The fastening means of the collars described above are particularly robust but require the bottle neck it has a thread or a cylindrical scope of a certain size. This type of collar is not applicable to all bottles, including some fuel gas bottles such as butane or propane whose neck is of reduced diameter. In addition, the threaded fastening means of the collars described above require a heavy and expensive construction. The assembly and disassembly of the collars described above can also be long and sometimes difficult. Indeed, the collar and neck of the bottle being metallic, they are likely to oxidize and seize with each other. In addition, clamping systems require handling screws and / or nuts over a number of turns. These screws and clamping nut are also likely to oxidize and seize. In the case where the collar comprises a bore disposed on a cylindrical seat, the adjustment is such that similarly the oxidation and / or the accumulation of dust and particles is likely to make it difficult to disassemble a collar and / or the reassembly of another necklace. Gold in the context of the refurbishment of gas cylinder, including fuel gas cylinders such as propane and butane, it is common that the collars must be replaced.

Description des modes de réalisationDescription of the embodiments

La figure 1 illustre la partie haute d'une bouteille de gaz 2 du type propane ou butane équipée d'un collier de préhension. Elle comprend essentiellement un contenant 6 en forme de bouteille, un robinet 8 de service vissé sur un col (non visible sur cette figure) de la bouteille 6 et un collier 4 de protection du robinet 8 et de préhension de la bouteille.The figure 1 illustrates the upper part of a gas cylinder 2 of the propane or butane type equipped with a gripping collar. It essentially comprises a container 6 in the form of a bottle, a service tap 8 screwed onto a neck (not visible in this figure) of the bottle 6 and a collar 4 for protecting the valve 8 and gripping the bottle.

Le collier de protection et de préhension 4 est détaillé à la figure 2. Il comprend essentiellement une base 10 s'étendant essentiellement dans un plan et une portion annulaire 14 en saillie depuis le périmètre de la base de manière à former avec la base un volume destiné à recevoir le robinet 8 (figure 1).The protection and gripping collar 4 is detailed in figure 2 . It essentially comprises a base 10 extending essentially in a plane and an annular portion 14 projecting from the perimeter of the base so as to form with the base a volume intended to receive the tap 8 ( figure 1 ).

La portion annulaire 14 comprend une encoche 36 au niveau de son bord supérieur 34 et s'étendant jusqu'à la base 10, cet encoche formant une ouverture d'accès au robinet de la bouteille. La portion annulaire 14 comprend également deux ouvertures radiales 18 suivant une direction généralement perpendiculaire à la direction radiale de l'encoche 36. Les zones de la portion annulaire 14 situées entre le bord supérieure 34 et les ouvertures radiales 18 forment des poignées 16 de préhension de la bouteille de gaz. Le reste de la portion annulaire 14 est généralement continue, c'est-à-dire sans ouverture majeure supplémentaire.The annular portion 14 comprises a notch 36 at its upper edge 34 and extending to the base 10, this notch forming an access opening to the valve of the bottle. The annular portion 14 also comprises two radial openings 18 in a direction generally perpendicular to the radial direction of the notch 36. The zones of the annular portion 14 located between the upper edge 34 and the radial openings 18 form grips 16 for gripping. the gas bottle. The rest of the annular portion 14 is generally continuous, that is to say without additional major opening.

La base 10 comprend une ouverture 12 essentiellement centrale. Elle est généralement circulaire et dimensionnée pour recevoir le col de la bouteille (visible à la figure 3, référence 42) et une collerette du robinet 8 (voir figure 1 et figure 3, référence 44). Elle comprend également deux encoches 32 et 33 (l'encoche 33 n'est visible qu'à la figure 3). Ces encoches sont diamétralement opposées et sont configurées pour permettre le passage au travers de l'ouverture 12 des bossages du robinet de service lors de la mise en place du collier 4 sur la bouteille pourvue du robinet. Cet aspect de l'invention sera détaillé plus loin en relation avec les figures 3 à 5.The base 10 comprises an essentially central opening 12. It is generally circular and dimensioned to receive the neck of the bottle (visible at the figure 3 , reference 42) and a flange of the valve 8 (see figure 1 and figure 3 , reference 44). It also includes two notches 32 and 33 (the notch 33 is visible only at the figure 3 ). These notches are diametrically opposed and are configured to allow passage through the opening 12 of the bosses of the service valve when placing the collar 4 on the bottle provided with the valve. This aspect of the invention will be detailed later in connection with the Figures 3 to 5 .

La base 12 comprend deux faces latérales 28 opposées préférentiellement généralement planes. Ces faces sont situées au niveau des ouvertures radiales 18. Ces faces forment des renfoncements par rapport au contour général du collier à hauteur de la base 10. Elles correspondent à une largeur de la base qui est inférieure à sa longueur selon une direction perpendiculaire à celle de ladite largeur.The base 12 comprises two opposing lateral faces 28 which are preferentially generally planar. These faces are situated at the level of the radial openings 18. These faces form recesses with respect to the general contour of the collar at the height of the base 10. They correspond to a width of the base which is less than its length in a direction perpendicular to that of said width.

La base 12 comprend dans son épaisseur deux orifices allongés 30. Ces orifices sont généralement rectilignes et parallèles l'un à l'autre. Ils s'étendent depuis une des faces latérales 28 et traversent l'ouverture centrale 12. Ils peuvent s'étendre jusqu'à la face latérale opposées de manière à déboucher de cette surface. Les axes des orifices allongés 30 sont essentiellement tangents au contour circulaire de l'ouverture centrale 12 de manière à ce que les orifices débouches partiellement dans le périmètre de ladite ouverture. En d'autres termes, l'enveloppe des orifices allongés 30 pénètre partiellement dans le périmètre de l'ouverture centrale 12 de manière à ce que les broches 22 correspondantes, lorsqu'elles y sont logées, respectivement, forment des bossages sur la surface interne de l'ouverture centrale 12, ces bossages formant des surface d'accrochage du collier.The base 12 comprises in its thickness two elongated orifices 30. These orifices are generally rectilinear and parallel to each other. They extend from one of the lateral faces 28 and pass through the opening central 12. They can extend to the opposite side face so as to emerge from this surface. The axes of the elongated orifices 30 are substantially tangent to the circular contour of the central opening 12 so that the orifices open partially into the perimeter of said opening. In other words, the envelope of the elongate orifices 30 partially penetrates the perimeter of the central opening 12 so that the corresponding pins 22, when they are housed therein, respectively, form bosses on the inner surface. of the central opening 12, these bosses forming gripping surfaces of the collar.

Les deux broches 22 peuvent être reliées entre elles par une portion de liaison 24 de manière à former une fourche 20. Il est toutefois à noter que les broches peuvent prendre d'autres formes comme par exemple des vis.The two pins 22 may be interconnected by a connecting portion 24 so as to form a fork 20. It should however be noted that the pins can take other forms such as screws.

La face latérale 28 de la base 10 comprend une cavité 26 reliant les deux orifices allongés 30 débouchant sur ladite face. Cette cavité 26 est dimensionnée pour recevoir la portion de liaison 24 de la fourche 20, de manière à empêcher une extraction de la fourche sans l'aide d'un outil, tel qu'un levier apte à exercer un effort sur ladite portion en prenant appui sur le bord de la cavité 26.The lateral face 28 of the base 10 comprises a cavity 26 connecting the two elongate holes 30 opening on said face. This cavity 26 is dimensioned to receive the connecting portion 24 of the fork 20, so as to prevent extraction of the fork without the aid of a tool, such as a lever able to exert a force on said portion taking support on the edge of the cavity 26.

Les figures 3 à 5 illustrent les différentes étapes de montage du collier 4 sur une bouteille de gaz 6.The Figures 3 to 5 illustrate the different steps of mounting the collar 4 on a gas cylinder 6.

A la figure 3, on peut observer que la bouteille 6 comprend à sa partie supérieure un col 42 suivant un axe vertical correspondant à l'axe longitudinal de la bouteille. Un robinet 8 est vissé sur ledit col 42, avec une collerette 44 venant en appui sur la face supérieure du col. La collerette 44 du robinet 8 présente un diamètre supérieur à celui du col de manière à former un rebord annulaire au sommet du col 42.To the figure 3 it can be seen that the bottle 6 comprises at its upper part a neck 42 along a vertical axis corresponding to the longitudinal axis of the bottle. A valve 8 is screwed onto said neck 42, with a flange 44 resting on the upper face of the neck. The flange 44 of the valve 8 has a diameter greater than that of the neck so as to form an annular flange at the top of the neck 42.

Toujours à la figure 3, on peut également observer que le robinet 8 comprend un raccord de sortie de service 38 ainsi qu'une vanne de surpression 40. Ces deux éléments sont diamétralement opposés et forment des bossages pour lesquels les encoches 32 et 33 de l'ouverture centrale 12 sont prévues. En effet, les encoches en question sont dimensionnées pouvoir recevoir ces bossages lorsque le collier est mis en position sur la bouteille par un mouvement de descente suivant l'axe longitudinal de la bouteille. Ce mouvement est illustré par les deux flèches dirigées vers le bas à la figure 3. Lors que de ce mouvement les broches de la fourche ne sont pas logées dans les orifices allongés au niveau de l'ouverture centrale, de manière à permettre la mise en place du collier 4 sur le col 42 de la bouteille 6.Always at the figure 3 it can also be observed that the valve 8 comprises a service outlet connection 38 and a pressure relief valve 40. These two elements are diametrically opposed and form bosses for which the notches 32 and 33 of the central opening 12 are provided. Indeed, the notches in question are sized to be able to receive these bosses when the collar is put in position on the bottle by a downward movement along the longitudinal axis of the bottle. This movement is illustrated by the two arrows pointing down to the figure 3 . When this movement the fork pins are not housed in the elongate holes at the central opening, so as to allow the establishment of the collar 4 on the neck 42 of the bottle 6.

A la figure 4, on peut observer qu'une fois le collier 4 mis en position suivant la direction longitudinale de la bouteille, il peut ensuite être pivoté d'environ un quart de tour, c'est-à-dire environ 90°, de manière à ce que l'encoche 36 de la portion annulaire 14 du collier 4 soit orientée en face du raccord de sortie de service 38 du robinet 8. Ce pivotement est autorisé compte tenu que les encoches 32 et 33 de l'ouverture centrale 12 ne sont plus en position d'engagement avec les bossages du robinet 8 (constitués du raccord de sortie de service 38 et de la vanne de surpression 40, voir figure 3). Le mouvement de pivotement du collier est illustré par les flèches à la figure 4.To the figure 4 it can be seen that once the collar 4 is positioned in the longitudinal direction of the bottle, it can then be rotated about a quarter of a turn, that is to say about 90 °, so that that the notch 36 of the annular portion 14 of the collar 4 is oriented opposite the service outlet connection 38 of the valve 8. This pivoting is authorized considering that the notches 32 and 33 of the central opening 12 are no longer in position. engagement position with the valve bosses 8 (consisting of the service outlet connector 38 and the pressure relief valve 40, see figure 3 ). The pivoting movement of the collar is illustrated by the arrows at figure 4 .

La figure 5 illustre la position finale du collier 4, avec le raccord de sortie de service 38 du robinet 8 en face de l'encoche 36 de la portion annulaire 14 du collier 4. La collerette 44 du robinet 8 est essentiellement au niveau de la face supérieure de la base 10 du collier 4. Les broches 22 peuvent alors être enfoncées dans leurs orifices allongés correspondant de manière à coopérer avec la collerette 44. Pour ce faire un effort d'enfoncement des broches 22 est exercé tout en maintenant le collier 4 en position sur la bouteille 6. La fourche 20 comprenant les broches peut alors être enfoncée jusqu'à ce que la portion de liaison soit logée dans la cavité 26 conformément à la position finale telle qu'illustrée à la figure 1.The figure 5 illustrates the final position of the collar 4, with the service outlet connection 38 of the valve 8 opposite the notch 36 of the annular portion 14 of the collar 4. The flange 44 of the valve 8 is essentially at the level of the upper face of the the base 10 of the collar 4. The pins 22 can then be driven into their corresponding elongated holes so as to cooperate with the collar 44. To do this, a driving force of the pins 22 is exerted while maintaining the collar 4 in position on the bottle 6. The fork 20 including the pins can then be depressed until the connecting portion is housed in the cavity 26 in accordance with the final position as illustrated in FIG. figure 1 .

Une collerette en matériau élastomère (non représentée) peut être disposée autour du col de la bouteille, entre sa face supérieure et la face inférieure de la base 10 du collier 4 de manière à générer des efforts de friction empêchant ou du moins limitant le pivotement du collier 4. Cette collerette peut présenter une épaisseur de plusieurs millimètres et une souplesse telle qu'elle permet de comprimer la collerette lors du montage du collier, notamment par application d'un effort manuel dirigé vers le bas au moment où les broches sont engagées dans leurs orifices et avec la collerette du robinet.A collar of elastomeric material (not shown) may be arranged around the neck of the bottle, between its upper face and the lower face of the base 10 of the collar 4 so as to generate friction forces preventing or at least limiting the pivoting of the collar 4. This collar may have a thickness of several millimeters and a flexibility such that it compresses the collar during assembly of the collar, in particular by applying a manual effort directed downwards. at the moment when the pins are engaged in their orifices and with the collar of the tap.

Le collier est préférentiellement en matériau plastique tel que du polypropylène PP ou du polyéthylène haute-densité PEHD. Il est alors préférentiellement d'un seul tenant, plus précisément venu de matière par moulage à injection.The collar is preferably made of plastic material such as polypropylene PP or high density polyethylene HDPE. It is then preferentially in one piece, more precisely come from material by injection molding.
