Description

L'invention concerne un capotage de protection pour récipient de gaz équipé d'un bloc robinet, avec ou sans détendeur intégré, et récipient de gaz équipé d'un tel capotage. Les gaz industriels et médicaux sont couramment conditionnés dans des récipients de gaz, typiquement des bouteilles de gaz, équipés d'un bloc robinet, avec ou sans détendeur intégré, à savoir un robinet simple de type ouvert/fermé ou un robinet à détendeur intégré, encore appelé RDI, permettant de contrôler débit et pression du gaz délivré. Afin de protéger ce bloc robinet, il est courant agencer au niveau du col de la bouteille de gaz et autour dudit bloc robinet, un capotage de protection formant coque protectrice autour dudit bloc robinet. Un tel capotage est couramment appelé « chapeau ». Par ailleurs, pour permettre d'accrocher l'ensemble bouteille/chapeau/robinet à un support, tel un barreau de lit d'hôpital, un brancard, une tringle ou support d'accrochage d'un véhicule d'urgence, par exemple une unité de SAMU ou analogue, il est usuel d'aménager sur le chapeau, un système d'accrochage fixe, telle une encoche en partie basse du chapeau, ou un système d'accrochage mobile, soit pivotant, soit rétractable. En outre, est également prévue une poignée de portage, généralement portée par un ou des montants-supports, laquelle fait partie intégrante de la coque du chapeau ou est fixée à celui-ci par vissage, collage ou toute autre technique adaptée. Un tel capotage à système d'accrochage mobile ou fixe est décrit par les documents EP-A-629812, DE-A-10057469, US-A-2004/020793 et EP-A-2586481. Toutefois, ces différents capotages existants présentent des inconvénients.The invention relates to a protective casing for gas container equipped with a valve block, with or without built-in expansion valve, and gas container equipped with such a cowling. Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or an integrated valve regulator, also called RDI, to control flow and pressure of the delivered gas. In order to protect this valve block, it is common to arrange at the level of the neck of the gas bottle and around said valve block, a protective cover forming a protective shell around said valve block. Such a cowling is commonly called "hat". Moreover, to allow the bottle / cap / tap assembly to be hooked to a support, such as a hospital bed bar, a stretcher, a rod or support for attaching an emergency vehicle, for example a SAMU unit or the like, it is customary to arrange on the cap, a fixed attachment system, such as a notch at the bottom of the cap, or a mobile attachment system, either pivoting or retractable. In addition, there is also provided a carrying handle, usually carried by one or support amounts, which is integral with the hull of the cap or is fixed thereto by screwing, gluing or any other suitable technique. Such a cowling mobile or fixed attachment system is described by documents EP-A-629812, DE-A-10057469, US-A-2004/020793 and EP-A-2586481. However, these different existing cowlings have disadvantages.

Ainsi, les capotages comprenant une poignée de transport et des montants-supports qui font partie intégrante de la coque se heurtent à des contraintes de fabrication. Par exemple, ils nécessitent la réalisation d'un moule complexe, ce qui complique la fabrication du capotage et conduit à des rebuts plus ou moins importants De plus, ils obligent à réaliser ces différentes parties en un même matériau, 30 typiquement en polymère, et ne permettent donc pas d'arriver à des capotages en matériaux mixtes, par exemple en partie en polymère et en partie en alliage d'aluminium. A l'inverse, les capotages réalisés en plusieurs parties fixées les unes aux autres, autorisent une plus grande souplesse de fabrication. Cependant, l'assemblage des différentes parties, les uns avec les autres, demande un 35 nombre plus élevé d'éléments de fixation, telles des vis ou analogues, ce qui augmente le coût global de fabrication du capotage.Thus, the cowlings comprising a carrying handle and support posts which form an integral part of the hull come up against manufacturing constraints. For example, they require the production of a complex mold, which complicates the manufacture of the cowling and leads to more or less important rejects. Furthermore, they require these different parts to be made of the same material, typically made of a polymer, and therefore do not allow to achieve cowlings of mixed materials, for example partly in polymer and partly in aluminum alloy. Conversely, cowls made in several parts fixed to each other, allow greater flexibility of manufacture. However, the assembly of the different parts with each other requires a greater number of fasteners, such as screws or the like, which increases the overall cost of manufacturing the shroud.

Un problème à résoudre est dès lors de proposer un capotage pour bouteille de gaz comprenant système d'accrochage et poignée de transport portée par un ou des montants-supports qui ne présente pas les inconvénients susmentionnés, en particulier qui soit d'assemblage facile grâce à un nombre de vis ou d'autre éléments de fixation limité, et à un temps d'assemblage plus réduit. La solution est alors un capotage de protection pour récipient de gaz, en particulier pour bouteille de gaz, équipé d'un bloc robinet, c'est-à-dire qu'il soit avec ou sans détendeur intégré, comprenant : - un corps de capotage formant coque protectrice délimitant un volume interne conçu pour recevoir tout ou partie du bloc robinet, - un dispositif d'accrochage pivotant autour d'un axe AA porté par le corps de capotage, et - au moins un montant-support porté par le corps de capotage, caractérisé en ce qu'un élément de fixation unique permet de solidariser le dispositif d'accrochage et au moins un montant-support au corps de capotage. Selon le cas, le capotage de protection de l'invention peut comprendre l'une ou plusieurs des caractéristiques techniques suivantes : - l'élément de fixation unique porte l'axe AA. - l'élément de fixation unique permet de solidariser le dispositif d'accrochage et deux montants-supports au corps de capotage. - les deux montants-supports se font face l'un à l'autre. - le ou les montants-supports portent une poignée de portage. - l'élément de fixation unique est choisi parmi les vis, les boulons, ou les systèmes de fixation par clipsage ou soudage. - le corps du capotage est formé de matériau polymère. - le ou les montants-supports sont formés de polymère ou d'un métal ou alliage métallique, en particulier en matériau plastique ou en alliage d'aluminium. - le matériau plastique est choisi parmi PVC, PE, PET, PP, PMMA, PU, PA... - la coque du capotage de protection comprenant une ou plusieurs ouvertures donnant accès au bloc robinet. - il comprend un volant rotatif de réglage du débit de gaz. - il comprend un manomètre indicateur de pression gazeuse. - il comprend un raccord de sortie permettant de délivrer du gaz à un débit désiré, ledit raccord pouvant être connecté à un appareil de distribution de gaz via un conduit flexible. - il comprend un raccord de remplissage permettant d'introduire du gaz dans la bouteille lorsque celle-ci est vide. - il comprend un raccord de sortie de gaz sous pression permettant de délivrer entre 4 et 5 bar environ. - la poignée de portage est fixée au(x) montant(s)-support(s) au moyen d'un ou plusieurs éléments de fixation, typiquement une ou des vis ou analogue. - le dispositif d'accrochage est agencé sur la face arrière du capotage. - le dispositif d'accrochage est fixé, via l'élément de fixation unique, au niveau de la moitié supérieure du capotage, de préférence au niveau du tiers supérieur du capotage. - le dispositif d'accrochage pivote selon un angle inférieur à 180°, entre une position dite totalement repliée et une position dite totalement dépliée dans laquelle le capotage peut être accroché à un support via ledit dispositif d'accrochage. - la poignée surmonte le haut du capotage, c'est-à-dire qu'elle est située au dessus du capotage. - il comprend un système de fixation permettant une solidarisation du capotage à une bouteille de gaz, de préférence au niveau du col de la bouteille, et/ou au bloc robinet agencé sur la bouteille. - il délimite un volume interne dimensionné pour recevoir tout le bloc robinet. L'invention porte aussi sur un récipient de gaz équipé d'un bloc robinet, qu'il soit avec ou sans détendeur intégré, caractérisé en qu'il comprend un capotage de protection selon l'invention agencé autour d'au moins une partie dudit bloc robinet. Selon le cas, le récipient de gaz de l'invention peut comprendre l'une ou plusieurs des caractéristiques techniques suivantes : - il est choisi parmi les bouteilles de gaz. - il est une bouteille de gaz ayant une taille comprise entre 10 et 150 cm. - il est une bouteille de gaz contenant de 0,5 à 20 litres (contenance en équivalent eau). - il est une bouteille de gaz de corps cylindrique creux. - il est une bouteille de gaz comprenant un col portant un orifice de sortie du gaz. - il est une bouteille de gaz contenant un gaz ou mélange gazeux choisi parmi 30 l'oxygène, l'air, un mélange N20/02, un mélange He/02, un mélange NO/azote ou tout autre gaz ou mélange gazeux. - le bloc robinet est de type à détendeur intégré, c'est-à-dire un RDI. - la bouteille est en acier, en un alliage d'aluminium ou en matériau composite. - la bouteille contient un gaz à une pression allant jusqu'à 350 bar (pression de 35 service).A problem to be solved is therefore to propose a rollover for a gas bottle comprising a hooking system and a carrying handle carried by one or several support posts which does not have the aforementioned drawbacks, in particular which is easy to assemble thanks to a number of screws or other limited fasteners, and a shorter assembly time.

L'invention concerne aussi une utilisation d'un récipient de gaz selon l'invention pour distribuer un gaz ou mélange gazeux, en particulier le gaz ou mélange gazeux est choisi parmi l'oxygène, air, N20/02, He/02 et NO/azote. L'invention va maintenant être mieux comprise grâce à la description détaillée suivante, faite à titre illustratif mais non limitatif, en référence aux figures annexées parmi lesquelles : - la Figures 1 représente une vue latérale d'un mode de réalisation d'un capotage de protection selon l'invention, et - la Figure 2 est une vue de 3/4 arrière du capotage de la Figure 1.The invention also relates to a use of a gas container according to the invention for dispensing a gas or gas mixture, in particular the gas or gas mixture is selected from oxygen, air, N20 / 02, He / 02 and NO /nitrogen. The invention will now be better understood thanks to the following detailed description, given by way of illustration but without limitation, with reference to the appended figures in which: FIG. 1 represents a side view of an embodiment of a rollover cover; protection according to the invention, and - Figure 2 is a rear view 3/4 of the cowling of Figure 1.

Les Figures 1 et 2 présentent un mode de réalisation d'un capotage de protection 1 rigide, couramment appelé « chapeau », agencé autour d'un bloc 3 robinet, à savoir un robinet avec ou sans détendeur intégré, lui-même fixé sur le col d'une bouteille de gaz 2. La bouteille de gaz 2 a une taille comprise entre 0 et 150 cm, et une contenance de 1 à 20 litres (en équivalent eau).Figures 1 and 2 show an embodiment of a rigid protective cover 1, commonly called "cap", arranged around a block 3 valve, namely a valve with or without built-in expansion valve, itself fixed on the neck of a gas cylinder 2. The gas cylinder 2 has a size between 0 and 150 cm, and a capacity of 1 to 20 liters (in water equivalent).

Le capotage de protection 1 sert principalement à protéger le bloc robinet 3 contre les chocs, qu'il avec détendeur intégré ou RDI, ou sans détendeur intégré. De façon générale, un capotage de protection 1 peut être ouvert ou fermé, c'est-à-dire présenter des ouvertures plus ou moins grandes donnant accès au bloc robinet 3 situé dans le volume interne du capotage 1. Lorsqu'il est fermé, le capotage 1 permet de préserver le robinet 3 des salissures et autres poussières. Par ailleurs, le robinet 3, typiquement un robinet de type RDI, comprend un volant rotatif 3a, manipulable par un utilisateur, pour contrôler le débit de gaz, un raccord de sortie de gaz 3b pour soutirer le gaz stocké dans la bouteille 2, un manomètre 3d pour contrôler la pression du gaz restante dans la bouteille, un raccord de remplissage 3e servant à introduire du gaz dans la bouteille 2 lorsque celle-ci est vide, et un raccord de sortie de gaz sous pression 3f Dans le mode de réalisation des Figures 1 et 2, le capotage de protection 1 comprend un corps de capotage 4 formant une coque protectrice autour d'un volume interne dimensionné pour recevoir le bloc robinet ou RDI 3, une poignée de portage 6 conçue pour être prise en main par un opérateur, ladite poignée de portage 6 étant formée d'un matériau rigide, et un ou plusieurs montants-supports 5 reliant mécaniquement le corps de capotage 4 à la poignée de portage 6, c'est-à-dire que le ou les montants-supports 5 sont solidarisés à la poignée de portage 6 de manière à permettre à un utilisateur de transporter facilement l'ensemble chapeau/robinet/bouteille.The protective cover 1 is mainly used to protect the valve block 3 against shocks, whether with built-in expansion valve or RDI, or without built-in expansion valve. In general, a protective cover 1 may be open or closed, that is to say have more or less large openings giving access to the valve block 3 located in the internal volume of the cowling 1. When closed, the cowling 1 preserves the valve 3 of dirt and other dusts. Furthermore, the valve 3, typically an RDI-type valve, comprises a rotary handwheel 3a, which can be manipulated by a user, to control the flow of gas, a gas outlet fitting 3b for withdrawing the gas stored in the bottle 2, a 3d pressure gauge for controlling the pressure of the gas remaining in the bottle, a filling connector 3e for introducing gas into the bottle 2 when the latter is empty, and a pressurized gas outlet connection 3f In the embodiment of Figures 1 and 2, the protective casing 1 comprises a casing body 4 forming a protective shell around an internal volume sized to receive the valve block or RDI 3, a carrying handle 6 designed to be handled by an operator , said carrying handle 6 being formed of a rigid material, and one or more support posts 5 mechanically connecting the casing body 4 to the carrying handle 6, that is to say that the one or more support-posts 5 are secured to the carrying handle 6 so as to allow a user to easily transport the cap / valve / bottle assembly.

Le corps 4 du capotage 1 est typiquement en un matériau de type polymère et/ou métal, préférentiellement en matériau plastique, tel que PVC, PE, PET, PP, PMMA, PU, PA... De même, les montants-supports 5 peuvent être formés d'un matériau plastique, comme le corps du capotage 1, mais aussi en alliage d'aluminium ou tout autre matériau métallique.The body 4 of the cowling 1 is typically made of a material of the polymer and / or metal type, preferably of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA. can be formed of a plastic material, such as the body of the cowling 1, but also aluminum alloy or any other metallic material.

Le corps 4 du capotage de protection 1 comporte en outre, dans sa face avant 4a, une (ou plusieurs) ouverture via laquelle un utilisateur peut avoir accès au volant rotatif 3a et au raccord de sortie de gaz 3b du bloc robinet ou RDI 3. De même, le manomètre 3d est agencé dans une autre ouverture située en face avant 4a du capotage 1 de manière à permettre à l'utilisateur une lecture aisée de la pression de gaz indiquée par ledit manomètre 3d.The body 4 of the protective casing 1 further comprises, in its front face 4a, one (or more) opening through which a user can have access to the rotary wheel 3a and the gas outlet fitting 3b of the valve block or RDI 3. Similarly, the pressure gauge 3d is arranged in another opening located in the front face 4a of the cowling 1 so as to allow the user easy reading of the gas pressure indicated by said pressure gauge 3d.

Afin de permettre l'accroche de l'ensemble bouteille/bloc robinet/capotage sur à un support, tel un barreau de lit d'hôpital ou de brancard, le capotage de protection 1 comprend, du côté de sa face arrière 4b, un dispositif d'accrochage 7 pivotant autour d'un axe AA, entre une position dite « totalement repliée » et une position dite « totalement dépliée », c'est-à-dire dans la position qu'il adopte lorsqu'il est accroché à un support. Typiquement, l'angle de pivotement entre ces deux positions extrêmes est inférieur ou égale à 170° mais supérieur ou égale à 0°, typiquement entre 90 et 170°, par exemple de l'ordre de 150°. Sur la Figure 1, un exemple de dispositif d'accrochage 7 est montré en position totalement repliée, alors que sur la Figure 2, il est représenté en position totalement dépliée. Dans ce cas, l'angle de pivotement entre ces deux positions est de l'ordre de 150°.In order to allow the assembly of the bottle / valve block / cowling assembly on a support, such as a hospital bed or stretcher bar, the protective casing 1 comprises, on the side of its rear face 4b, a device 7 pivoting about an axis AA, between a position called "fully folded" and a position called "fully unfolded", that is to say in the position it adopts when attached to a support. Typically, the pivot angle between these two extreme positions is less than or equal to 170 ° but greater than or equal to 0 °, typically between 90 and 170 °, for example of the order of 150 °. In Figure 1, an example of attachment device 7 is shown in the fully folded position, while in Figure 2, it is shown in fully unfolded position. In this case, the pivot angle between these two positions is of the order of 150 °.

L'assemblage du capotage de protection 1 et sa fixation autour du bloc de robinet 3 porté par la bouteille de gaz 2, se fait par vissage au moyen d'éléments 8 de fixation, à savoir des vis ou analogues. Plus précisément, le capotage de protection 1 comprend plusieurs sous-unités fixées les unes aux autres, à savoir principalement le corps de capotage 4, qui peut être formé lui- même d'un ou plusieurs composants, le ou les montants-supports 5 portant la poignée 6 et le dispositif d'accrochage 7. Selon l'invention, afin de faciliter l'assemblage en minimisant le nombre de vis 8 et en réduisant le temps d'assemblage, le dispositif d'accroche 7 est monté sur le corps 4 du capotage de protection 1 via l'une 8a des vis d'assemblage 8, qui permet non seulement une solidarisation du dispositif d'accroche 7 au corps 4 du capotage 1 et son articulation par rapport à celui-ci, à savoir son pivotement angulaire, mais aussi la fixation d'un ou des montants-supports 5. En d'autres termes, on utilise un élément de fixation unique, telle une vis 8a unique, pour fixer le ou les montants-support 5 et le dispositif d'accrochage 7 pivotant au corps de capotage 4 et pour assurer le pivotement du dispositif d'accrochage 7 par rapport au capotage 1 entre les positions totalement repliée et totalement dépliée, et inversement. L'élément de fixation unique, telle une vis 8a unique, constitue donc l'axe AA de pivotement du dispositif d'accrochage 7. L'élément de fixation unique 8 peut être une vis, boulon, ou tout autre système d'assemblage par soudage ou par clipsage. Le récipient de gaz 2 équipé du bloc robinet 3 protégé par le capotage 1 selon l'invention est particulièrement bien adapté à une utilisation dans le domaine médical, notamment en hôpital, à domicile ou dans une unité mobile d'intervention d'urgence, type SAMU ou ambulance.The assembly of the protective casing 1 and its fixing around the valve block 3 carried by the gas cylinder 2, is done by screwing by means of fastening elements 8, namely screws or the like. More specifically, the protective casing 1 comprises several subunits attached to each other, namely mainly the casing body 4, which can itself be formed of one or more components, or the support pillars 5 carrying the handle 6 and the attachment device 7. According to the invention, to facilitate assembly by minimizing the number of screws 8 and reducing the assembly time, the attachment device 7 is mounted on the body 4 of the protective casing 1 via one 8a of the assembly screws 8, which allows not only a fastening of the attachment device 7 to the body 4 of the cowling 1 and its articulation relative thereto, namely its angular pivoting , but also the fixing of one or more support-supports 5. In other words, a single fastening element, such as a single screw 8a, is used to fasten the support pillar (s) 5 and the attachment device 7 pivoting to the casing body 4 and to ensure the pivoteme nt of the attachment device 7 relative to the cowling 1 between the fully folded and fully unfolded positions, and vice versa. The single fastening element, such as a single screw 8a, therefore constitutes the axis AA of pivoting of the attachment device 7. The single fastening element 8 can be a screw, bolt, or any other assembly system. welding or clipping. The gas container 2 equipped with the valve block 3 protected by the cowling 1 according to the invention is particularly well suited for use in the medical field, including hospital, home or in a mobile emergency response unit, type EMS or ambulance.
