    专利说明:

    [0001] The present invention relates to a protective casing, also called cap, for gas cylinders, in particular medical gas, equipped with an attachment device on beds, stretchers, armchairs or others, coming to conform to the outer contours of the casing body when folded into its rest position. 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.
    [0002] In fact, there are two types of hanging systems, namely fixed and moving. As an example of a fixed attachment system, mention may be made notches, hooks or similar arranged carried by the cowling, either during the manufacture of the body of the cowl itself and which are integral part or are fixed to the rollover body after 25 stroke. By way of example of a mobile attachment system, mention may be made of pivoting or translational supports which are fixed to the rear face or to a lateral face of the cowling. Covers for gas cylinders with a fixed or movable attachment system are described in EP-A-629812, DE-A-10057469, US-A-2004/020793 and EP-A30 2586481. However, these various cowlings and existing fastening systems have drawbacks. Thus, many hooking systems extend beyond the body of the bottle, even when they are folded into their rest position, which leads to increasing the large size of the bottle / cowling assembly.
    [0003] However, increasing the overall size of the assembly generates easily understandable storage problems bottles and equipped, particularly storage in racks or other baskets for their grouped transport. In addition, the fact that many exceed the pivoting hooking systems of the general diameter of the bottle, even folded, is a source of accidents for users whose clothing for example can inadvertently catch on the system and cause a fall on the floor of the bottle, with a risk of injury to nearby staff. Others are complicated in architecture and / or impractical to handle. There is also a cowling having a specific housing in which is inserted a pivoting arm. If this makes it possible to prevent the arm from protruding from the casing body when it is folded over, this also has the major drawback of making the inner parts of the casing and of the attachment device more complicated and of generating a inevitable accumulation of dust and other dirt over time in these areas of the cowling, that is to say a state of cleanliness not very compatible with use in hospitals. In addition, the manipulation of this pivoting arm is not necessarily easy for the user who can jam the fingers during its deployment and the attachment of the assembly to a support, such as a hospital bed bar . In view of this, the problem that arises is to provide a protective casing or cap for a gas cylinder comprising an improved attachment device does not have the aforementioned drawbacks. The solution of the invention is a protective casing or "cap" for a gas container, in particular for a gas cylinder, equipped with a valve block, with or without an integrated regulator, comprising: a casing body forming a protective shell defining an internal volume designed to receive all or part of the valve block, and - a hooking device pivoting between several angular positions comprising: a rest position in which the attachment device is completely folded, that is to say in contact or quasi-contact with the body of the cowling, and. a hooking position in which the attachment device is completely unfolded, that is to say completely out so as to allow the attachment of the cowling to a support, such as a bed rail or the like, characterized in that the attachment device comprises a three-dimensional structure comprising two arms each carrying a notch for fixing to a support, said three-dimensional structure comprising an inner face shaped to fit the outer profile of the casing body, when the attachment device is in position resting, that is to say, it is completely folded and positioned around the cowling. Depending on the case, the protective cowling according to the invention may comprise one or more of the following technical characteristics: the attachment device is pivotally fixed around an axis AA situated on the rear face of the body of the cowling; . - The rear face and / or the side faces of the cowling body is / are shaped to have an outer profile complementary to the inner face of the three-dimensional structure. the rear face and / or the lateral faces of the cowling body have at least one impression made in the outer shell of the body in which at least a portion of the three-dimensional structure is housed while marrying the outer profile of the said at least one impression . the three-dimensional structure comprises at least one curved inner face. the three-dimensional structure has a generally curved shape. - It comprises a locking system for locking and holding the fastening device in the rest position. - The hooking device pivots between the rest position and the attachment position of an angle (a) less than 180 °, typically between 90 ° and 170 °, preferably at least 110 °. - It comprises at least one support amount integral with the casing body and carrying a carrying handle. the body of the cowling and the three-dimensional structure are formed of polymer material. Typically, the polymeric material is a plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA ... - the two arms are connected to each other by at least one element of junction, preferably the two arms and said at least one connecting element are formed in one piece, in particular by molding. - It comprises a locking system for locking and holding the fastening device 30 in the rest position. Furthermore, the invention also relates to a gas container equipped with a valve block, whether with or without integrated expansion valve, characterized in that it comprises a protective cover according to the invention arranged around at least a portion of said valve block.
    [0004] As the case may be, the gas container of the invention may comprise one or more of the following technical characteristics: it is chosen from gas bottles. - It is a gas cylinder with a size between 10 and 150 cm. - it is a bottle of gas containing from 0.5 to 20 liters (capacity in water equivalent). - It is a cylinder of hollow cylindrical body gas. - It is a gas cylinder comprising a neck carrying a gas outlet orifice. it is a gas cylinder containing a gas or gas mixture chosen from oxygen, air, an N 2 O 2/2 mixture, an He / O 2 mixture, a NO / nitrogen mixture or any other gas or gaseous mixture. - The valve block is integrated pressure reducer type, that is to say an RDI. the bottle is made of steel, an aluminum alloy or a composite material. the bottle contains a gas at a pressure of up to about 350 bar. The invention also relates to a use of a gas container according to the invention for dispensing a gas or gas mixture, in particular a 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 view of the front face of a protective casing according to FIG. the invention equipping a gas cylinder, - Figure 2 shows a view of the rear face of the cowling of Figure 1, - Figure 3 is a rear view of 3/4 of the cowling of Figure 1, and - Figure 4 shows an assembly formed of a gas cylinder equipped with the cowling 25 of Figure 1 seen in supine position on a surface. Figures 1 to 4 show an embodiment of a protective cover 1 rigid, commonly called "hat", arranged around a valve block, namely a valve with or without built-in regulator, itself attached to the neck The gas cylinder 10 typically has a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent). The protective cover 1 serves to protect the faucet block against shocks, that said valve block is of the type with integrated pressure reducer or RDI, or of the type without integrated regulator. As such, the protective casing 1 comprises a casing body 2 forming a protective shell around an internal volume sized to receive the valve block, a carrying handle 4 designed to be handled by an operator, said handle carrier 4 being formed of a rigid material, and carried by one or more support-posts 5 mechanically connecting the body 2 of the cowling to the carrying handle 4, that is to say that the support-holder (s) 5 are secured to the carrying handle 4 so as to allow a user to easily transport the cap / tap / bottle assembly.
    [0005] The body 2 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 ... Similarly, the support-frames 5 can be formed of a plastic material, such as the body of the cowling 1, but also aluminum alloy or any other metallic material. The protective casing 1 also has openings giving access to the valve block located in the internal volume of the body 2 of the cowling 1, in particular the connections, rotary wheel .. Indeed, the valve block, typically a type RDI tap, comprises, as illustrated in FIG. 3, a rotating handwheel 7, situated on the front face 2a, manipulable by a user to control the flow of gas, a gas outlet fitting 8 for withdrawing the gas stored in the bottle 10, a pressure gauge 9 for controlling the pressure of the gas, a filling connector 15 (Fig.2 and 3), located on the rear face 2b, for introducing gas into the bottle 10 when the latter is empty, and a gas outlet connection under pressure 17 The assembly of the protective casing 1 and its fixing around the valve block carried by the gas cylinder 10, is made by screwing by means of fasteners, namely screws or the like. In order to allow the catch / stowage of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective casing 1 comprises, on the side of its rear face 2b. , an attachment device 3 pivoting about an axis AA, between a fully folded position, called "rest", that is to say the position adopted by the attachment device 3 when stored and in contact or quasi-contact with the body 2 of the cowling 1, and a completely unfolded position called "hooking", that is to say the position adopted by the hooking device 3 when it is completely out and can be hooked to a support, such as a bed rail or the like. Thus, Figure 2 shows the attachment device 3 in the rest position, that is to say folded, while Figures 3 and 4 show the attachment device 3 in the attachment position, that is to say to say totally unfolded. These two positions therefore constitute the extreme angular positions that can adopt the attachment device 3 when pivoting about the axis AA.
    [0006] Typically, the pivot angle α between these two extreme angular positions is less than or equal to 170 ° and greater than 0 °, preferably greater than 90 °, for example an angle of the order of 150 °. In order to solve some of the problems posed by known attachment devices, in the context of the present invention, care is taken to ensure perfect integration of the attachment device 3 around the body 2 of the protective casing 1. To do this, the 3 attachment device according to the invention forms a curved three-dimensional structure 3, 6a, 6b, 11a, 1 lb coming to conform to the contours of the casing body 2, when the attachment device 3 is in the rest position, it is that is, folded as illustrated in FIG. 2. More precisely, the three-dimensional curved structure 3, 6a, 6b, 11a, 1b comprises two arms 6a, 6b, namely a right arm 6a and a left arm 6b, coming to take the sandwich body 2, when the attachment device 3 is in the rest position. Each of the arms 6a, 6b carries a fixing notch 11a, 1b for fastening the assembly to a support, such as a hospital bed bar or the like. Each fixing notch 11a, 1 lb has an arcuate shape, for example shaped in a circular arc, so as to marry at best the shape of a tubular bar of bed, stretcher, wheelchair or other. The three-dimensional structure 3, 6a, 6b, 11a, 11b comprises, in turn, an inner face 13 shaped to fit the outer profile 14, that is to say the outer surface or contour, of the body 2 rollover 1 so as to minimize the overall size of the cowling 1, when the attachment device 3 is folded as in Figure 2. Thus, as shown in Figure 3, the face 13 perfectly fits the outer contour of the rear face 2b of the cowling 1 by being inserted into the cavity 14 formed in the body 2 of the cowling 1, which fingerprint 14 has a shape complementary to that of the three-dimensional structure 3, 6a, 6b, 11a, 1 lb, when the structure three-dimensional 3, 6a, 6b, 11a, 1 lb is in its rest position or fully folded, as shown in Figure 2. In other words, to increase the integration of the three-dimensional structure 3, 6a, 6b, 11a, 1 lb in the body 2 of the cowling 1, provision is made for r on the contour of the casing body 2 2, at least one specific footprint 14 which is adapted and shaped to receive all or part of the three-dimensional structure 3, 6a, 6b, 11a, 1 lb which is then housed therein folded position, that is to say rest. Thus, when the three-dimensional structure 3, 6a, 6b, 11a, 1b is folded, it does not or almost does not protrude externally and does not increase the overall size of the cowling 1.
    [0007] The three-dimensional structure 3, 6a, 6b, 11a, 11b, in addition to the hooking on a support such as a hospital bed bar or the like, has another function which is to stabilize the bottle 10 in a horizontal position to prevent it does not roll on the ground or on any other surface. To do this, the three-dimensional structure 3, 6a, 6b, 11a, 11b, once fully unfolded so in its hooking position, can serve as crutches to the bottle 10 when lying horizontally, as illustrated in FIG. Figure 4. Furthermore, in an alternative embodiment, the three-dimensional structure 3, 6a, 6b, 11a, 11b is shaped to allow protection of the filling connector 15 dust, weather, misuse ... To this end, the opening or spacing 12 between the two arms 6a, 6b can be filled and form a protective cover covering the filling connector 15 located on the rear face 2b of the body 2, when the three-dimensional structure 3, 6a, 6b, 11a, 1b is in the rest position, that is to say folded against the body 2 of the cowling 1.
