Description

La présente invention concerne un capotage de protection, encore appelé chapeau, pour bouteilles de gaz, en particulier de gaz médical, muni d'une poignée de portable revêtue d'un matériau améliorant le confort d'utilisation et un récipient de gaz, telle une bouteille, équipée d'un tel capotage.The present invention relates to a protective cover, also called cap, for gas bottles, in particular medical gas, provided with a portable handle coated with a material improving the comfort of use and a gas container, such a bottle, equipped with such a cowling.

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 contrôlant uniquement le débit de gaz ou un robinet à détendeur intégré, encore appelé RDI, permettant de contrôler débit et pression du gaz délivré.Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without a built-in regulator, ie a simple valve controlling only the flow of gas or an integrated regulator valve. , also called RDI, to control flow and pressure of the delivered gas.

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 rigide autour dudit bloc robinet. Un tel capotage est couramment appelé « chapeau ».In order to protect this valve block, it is common to arrange at the neck of the gas bottle and around said valve block, a protective cover forming a rigid protective shell around said valve block. Such a cowling is commonly called "hat".

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 ou mobile, notamment pivotant.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 or mobile, including pivoting.

Afin de faciliter le transport et les manipulations de l'ensemble bouteille/bloc robinet/capotage, il est usuel de doter le capotage d'une poignée de transport qui, en général, le surmonte et permet son portage manuel à une main par les utilisateurs.In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by users. .

Des capotages de ce type sont décrits notamment par les documents EP-A-629812 , DE-A-10057469 , US-A-2004/020793 et EP-A-2586481 .Cowlings of this type are described in particular by the documents EP-A-629812 , DE-A-10057469 , US-2004/020793 and EP-A-2586481 .

Toutefois, les poignées actuelles ne sont pas très confortables et ce, qu'elles soient moulées d'une pièce avec tout ou partie du capotage, en polymère ou en métal, ou qu'elles y soient fixées après coup, par soudage, avec des vis ou par tout autre moyen.However, the current handles are not very comfortable and they are molded in one piece with all or part of the casing, polymer or metal, or they are attached thereafter, by welding, with screw or by any other means.

Dans certains cas, on a même pu constater de légères blessures aux mains de certains utilisateurs, lesquelles ont été causées par des poignées présentant des aspérités trop importantes.In some cases, even slight injuries have been observed in the hands of some users, which have been caused by handles with excessive asperities.

On connait par ailleurs le document FR-A-2897920 décrivant une bonbonne de gaz, notamment de GPL, équipée d'un chapeau métallique de forme tubulaire muni d'une anse mobile de forme général en C avec partie centrale formant poignée de préhension, laquelle est recouverte d'un matériau présentant une dureté Shore entre 50 et 95, typiquement un revêtement de PVC. Cette solution n'est pas idéale car la bonbonne proposée n'est pas conçue pour être accrochée à un support et si la poignée de portage est utilisée à cette fin, il existe des risques de chute, de décrochage, voire de blessure de l'utilisateur qui peut se coincer les doigts en tentant de l'accrocher.We also know the document FR-A-2897920 describing a gas cylinder, in particular LPG, equipped with a tubular metal cap provided with a generally C-shaped movable handle with a central part forming a gripping handle, which is covered with a material having a Shore hardness between 50 and 95, typically a PVC coating. This solution is not ideal because the proposed bottle is not designed to be attached to a support and if the carrying handle is used for this purpose, there is a risk of falling, stalling or even injury of the user who can pinch his fingers while trying to hang it.

Par ailleurs, le document US-A-3,813,729 enseigne une poignée de portage destinée à une radio, une télévision, une valise, un instrument de musique ou tout autre boitier de transport qui comprend un revêtement surfacique en résine thermoplastique surmoulée, tel que polypropylène, ABS, vinyle rigide, polystyrène... Ce document ne concerne pas les bouteilles de gaz.In addition, the document US Patent 3,813,729 teaches a carrying handle intended for a radio, a television, a suitcase, a musical instrument or any other transport case which comprises a surface covering of overmolded thermoplastic resin, such as polypropylene, ABS, rigid vinyl, polystyrene, etc. document does not concern gas cylinders.

En outre, le document US-A-2005/0211300 décrit une bonbonne de gaz équipée d'un robinet entourée d'une collerette protectrice à laquelle vient se fixer, de manière amovible, une sorte de coupe surmontée d'une poignée de portage. La coupe vient couvrir le robinet et le protège pendant son transport. Là encore, cette solution n'est pas idéale car il existe un risque de décrochage de la poignée et donc de blessure de l'utilisateur, et que par ailleurs une fois le transport opéré et la coupe protectrice enlevée, le robinet n'est plus efficacement protégé.In addition, the document US-2005/0211300 discloses a gas cylinder equipped with a valve surrounded by a protective flange to which is fixed removably, a kind of cup surmounted by a carrying handle. The cup covers the faucet and protects it during transport. Again, this solution is not ideal because there is a risk of stalling the handle and therefore the user's injury, and that also once the transport operated and the protective cut removed, the valve is no longer effectively protected.

Au vu de cela, le problème qui se pose est d'améliorer le confort de portage des capotages de protection ou chapeaux pour bouteille de gaz en évitant les inconvénients susmentionnés tout en proposant un capotage de protection pouvant être transporté par un utilisateur et aisément accroché à un support, tel un barreau de lit d'hopital.In view of this, the problem that arises is to improve the wearing comfort of protective covers or caps for gas cylinder avoiding the aforementioned drawbacks while providing a protective cover that can be transported by a user and easily hooked to a support, such as a hospital bed rail.

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 Figure 1 représente une vue de la face avant d'un capotage de protection selon l'invention et
  • la Figure 2 représente une vue de la poignée du capotage de la Figure 1.
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 among which:
  • the Figure 1 represents a view of the front face of a protective cowling according to the invention and
  • the Figure 2 represents a view of the handle of the cowling of the Figure 1 .

La Figure 1 présente un mode de réalisation d'un capotage de protection 1 rigide, couramment appelé « chapeau », agencé autour d'un bloc robinet (non visible), à savoir un robinet avec ou sans détendeur intégré, lui-même fixé sur le col d'une bouteille de gaz 2, ledit capotage de protection étant muni d'une poignée de transport 6 selon la présente invention.The Figure 1 presents an embodiment of a rigid protective cover 1, commonly called "hat", arranged around a valve block (not visible), namely a valve with or without built-in expansion valve, itself attached to the neck of a gas cylinder 2, said protective cowl being provided with a carrying handle 6 according to the present invention.

La bouteille de gaz 2 a typiquement une taille entre 10 et 150 cm, et une contenance de 0,5 à 20 litres (en équivalent eau).The gas bottle 2 typically has a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).

Le capotage de protection 1 permet de protéger le bloc robinet contre les chocs, que le dit bloc robinet soit du type avec détendeur intégré ou RDI, ou du type sans détendeur intégré.The protective casing 1 makes it possible to protect the faucet block against shocks, whether said valve block is of the type with integrated expansion valve or RDI, or of the type without integrated expansion valve.

Plus précisément, le capotage de protection 1 comprend un corps 8 de capotage formant une coque protectrice autour d'un volume interne dimensionné pour recevoir le bloc robinet, une poignée de portage 6 conçue pour être prise en main par un opérateur.More specifically, the protective casing 1 comprises a casing body 8 forming a protective shell around an internal volume sized to receive the valve block, a carrying handle 6 designed to be handled by an operator.

La poignée de portage 6 est formée d'un matériau rigide, tel un polymère ou un métal ou alliage métallique, et est portée par un ou plusieurs montants-supports 5 reliant mécaniquement le corps 8 de capotage à la poignée de portage 6.The carrying handle 6 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is carried by one or more support posts 5 mechanically connecting the casing body 8 to the carrying handle 6.

La poignée de portage 6 est généralement agencée horizontalement, c'est-à-dire perpendiculairement ou quasi-perpendiculairement par rapport à l'axe vertical de la bouteille 2 et du capotage 1.The carrying handle 6 is generally arranged horizontally, that is to say perpendicularly or quasi-perpendicularly with respect to the vertical axis of the bottle 2 and the cowling 1.

La poignée de portage 6 a une forme longiligne, qu'elle soit rectiligne ou incurvée, typiquement une longueur inférieure à 20 cm, typiquement de 6 à 15 cm.The carrying handle 6 has an elongated shape, whether rectilinear or curved, typically a length less than 20 cm, typically 6 to 15 cm.

Le ou les montants-supports 5 sont fixés à l'une ou aux deux extrémités 9, 10 de la poignée de portage 6 de manière à permettre à un utilisateur de transporter facilement l'ensemble chapeau/robinet/bouteille au moyen de ladite poignée de portage 6.The one or more support posts 5 are fixed at one or both ends 9, 10 of the carrying handle 6 so as to allow a user to easily transport the hat / tap / bottle assembly by means of said handle. porterage 6.

Le corps 8 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. Ils peuvent être fixés à la poignée 6 par vissage ou soudage, par exemple.The body 8 of the cowling 1 is typically made of a polymer and / or metal type material, preferably made 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. They can be attached to the handle 6 by screwing or welding, for example.

Le capotage de protection 1 présente par ailleurs des ouvertures donnant accès au bloc robinet situé dans le volume interne du corps 8 de capotage 1, en particulier aux raccords 13, au volant rotatif 12..., ainsi qu'à un manomètre 11. En effet, le bloc robinet, typiquement un robinet de type RDI, comprend, comme illustré en Figure 1, un volant rotatif 12, situé en face avant, manipulable par un utilisateur pour contrôler le débit de gaz, un raccord de sortie de gaz 13 pour soutirer le gaz stocké dans la bouteille 2, un manomètre 11 pour contrôler la pression du gaz, un raccord de remplissage, (non visible) situé en face arrière, servant à introduire du gaz dans la bouteille 2 lorsque celle-ci est vide, et un raccord de sortie de gaz sous pression 14, agencé en face latérale du capotage.The protective casing 1 also has openings giving access to the valve block located in the internal volume of the body 8 of the cowling 1, in particular the connectors 13, the rotary wheel 12 ..., and a pressure gauge 11. In Indeed, the valve block, typically an RDI-type tap, comprises, as illustrated in FIG. Figure 1 , a rotary wheel 12, located on the front face, manipulable by a user to control the flow of gas, a gas outlet connector 13 for withdrawing the gas stored in the cylinder 2, a pressure gauge 11 for controlling the pressure of the gas, a filling connector, (not visible) located on the rear face, for introducing gas into the bottle 2 when it is empty, and a pressurized gas outlet connector 14, arranged on the lateral side of the cowling.

La fixation autour du bloc de robinet sur le col de la bouteille de gaz 2 se fait par vissage.The fixing around the valve block on the neck of the gas cylinder 2 is done by screwing.

Afin de permettre l'accroche ou l'arrimage de l'ensemble bouteille/bloc robinet/capotage 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, un dispositif d'accrochage 15 pivotant, entre une position totalement repliée, dite « de repos » (schématisé en Figure 1), c'est-à-dire la position adoptée par le dispositif d'accrochage 15 lorsqu'il est rangé et en contact ou quasi-contact du corps 8 du capotage 1, et une position totalement dépliée dite « d'accrochage », c'est-à-dire la position adoptée par le dispositif d'accrochage 15 lorsqu'il est complètement sorti et peut être accroché à un support, tel un barreau de lit ou analogue.In order to make it possible for the bottle / tap / cowl assembly to be hooked or secured to a support, such as a hospital bed or stretcher bar, the protective casing 1 comprises, on the side of its rear face, a pivoting attachment device 15 between a fully folded position, called "rest" (schematized in Figure 1 ), that is to say the position adopted by the attachment device 15 when stored and in contact or near-contact body 8 of the cowling 1, and a fully unfolded position called "hooking", that is to say the position adopted by the attachment device 15 when it is fully extended and can be hooked to a support, such as a bed rail or the like.

Conformément à l'invention, comme détaillé sur la Figure 2, afin d'améliorer le confort pour l'utilisateur et éviter les blessures lors des manipulations de l'ensemble, la poignée de portage 6, qui est conçue pour être prise en main par un opérateur, est formée d'une âme ou structure centrale 3 interne longiligne en matériau rigide, tel du plastique ou un métal ou alliage métallique, dont la surface externe 7 est recouverte d'un matériau souple présentant une dureté Shore A entre 0 et 100According to the invention, as detailed on the Figure 2 , in order to improve comfort for the user and to avoid injuries during handling of the assembly, the carrying handle 6, which is designed to be handled by an operator, is formed of a core or central structure 3 internal elongate rigid material, such as plastic or a metal or metal alloy, whose outer surface 7 is covered with a flexible material having a hardness Shore A between 0 and 100

La dureté Shore se mesure classiquement au moyen d'un duromètre Shore, par exemple le testeur de dureté Shore PCE-HT 150 ou le mesureur de dureté PCE-DX A Shore A disponibles dans le commerce.Shore hardness is conventionally measured by means of a Shore durometer, for example the Shore hardness tester PCE-HT 150 or the commercially available PCE-DX A Shore A hardness tester.

L'épaisseur de la couche de matériau 7 souple peut aller jusqu'à quelques millimètres. Toutefois, des épaisseurs supérieures ou inférieures sont également utilisables. L'épaisseur à adopter peut être choisie via de simples essais empiriques en fonction du matériau souple/mou choisi et du niveau de confort de toucher que l'on souhaite donner à l'utilisateur.The thickness of the flexible material layer 7 can be up to a few millimeters. However, higher or lower thicknesses are also usable. The thickness to be adopted can be chosen via simple empirical tests according to the soft / soft material chosen and the level of comfort of touch that it is desired to give to the user.

La (ou les) couche de matériau souple peut être appliquée par moulage autour de l'âme centrale 3 de la poignée 6 ou par dépôt sur celle-ci d'une peinture de type à effet dit « soft touch » (effet doux et soyeux).The layer (or layers) of flexible material may be applied by molding around the central core 3 of the handle 6 or by depositing on it a so-called "soft touch" effect paint (soft and silky effect ).

Dans tous les cas, on obtient un capotage 1 agréable à soulever et à transporter pour un utilisateur, sans risque de blessure et de confort d'utilisation amélioré.In all cases, we obtain a cowling 1 pleasant to lift and carry for a user, without risk of injury and improved comfort of use.
