    专利说明:

    The present invention relates to a protective cover for gas containers, in particular medical gas bottles, equipped with a pivoting attachment device, making it possible to hang the cover on a bed, a stretcher, an armchair or the like, as well as 'A gas container, such as a gas cylinder, fitted with such a protective cover arranged around a valve block, with or without an integrated regulator.
    Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders or cylinders, equipped with a valve block, with or without an integrated regulator, i.e. a simple valve of the open / closed type or a regulator valve integrated, also called RDI, allowing to control flow and pressure of the delivered gas.
    In order to protect this valve block, more simply called a "valve", it is common to arrange, at the neck of the gas cylinder and around the valve block, a protective cover forming a protective shell around the valve block. Such a cowling is commonly called a "hat".
    In addition, to allow the bottle / cap / tap assembly to be hung on a support, such as a hospital bed bar, a stretcher, a rod or hanging bracket for an emergency vehicle, for example a SAMU or similar unit, it is usual to arrange a hanging system on the hat.
    There are fixed and other mobile attachment systems, in particular translating or pivoting, for example those described by documents EP-A-629812, DE-A-10057469, US-A-2004/020793 and EP-A -2586481.
    Certain casings with pivoting attachment system have a specific housing in which a pivoting arm is inserted or have an external surface shaped to accommodate the pivoting arm when it is completely folded, that is to say in its position of storage along and in contact with the external surface of the enclosure. Examples include EP-A-2918893 and WO-A-2015/132092.
    However, casings with pivoting latching system often have a major drawback, namely that the latching device is not kept in its rest position and / or in its unfolded, that is to say active, position. serving for the attachment of the assembly to a bed bar or the like, except providing a specific mechanism ensuring the blocking of the attachment device, which specific mechanism complicates the architecture of the cowling.
    However, if the fastening device is not maintained, it can be a source of injury for the user because it can unfold or, conversely, fold up unexpectedly and cause pinching of the hands or fingers, or other injuries.
    From there, when deploying the attachment device of a cowling fitted to a gas cylinder, one must at the same time hold the bottle via its carrying handle and hold the deployed attachment device with another hand.
    In addition to being not very ergonomic, this way of creating generates, as already said, a risk for the user to pinch his fingers or hand between the hanging device and the support at the time of hanging.
    In view of this, the problem which arises is to propose a protective cover or cap for a gas container, typically for a gas bottle, comprising an improved pivoting hooking device which does not have the abovementioned drawback (s), in particular which allows the attachment device to be maintained in a stable position when it is unfolded or folded, and easy passage from one position to the other, without causing significant complexification of the rollover and reducing the risk of injury for the user.
    The solution of the invention is a protective cover or "cap" for a gas container, in particular for a gas bottle, equipped with a valve block, with or without an integrated regulator, comprising:
    a cover body forming a protective shell delimiting an internal volume designed to receive all or part of the valve unit, and
    - a hooking device pivoting around an axis AA, called a "rotation axis", between several angular positions comprising a rest position in which the hooking device is completely folded and a hooking position in which the device hook is unfolded, characterized in that:

    each housing is configured to present at least 3 successive sections comprising a first end section and a second end section connected to one another by an intermediate section, the first and second end sections having a profile internal of generally semicircular shape, and the intermediate section having an oblong shape, the first and the second end section being separated from the intermediate section by wall restrictions projecting radially towards the interior of the intermediate section, and
    - Each finger from being positioned in the first end section of the housing in which it is inserted, when the attachment device is in the attachment position and in the second end section of said housing, when the attachment device is in the rest position.

    - the carrying handle extends between the support uprights.
    - the support uprights are fixed to the cowling by a proximal end.
    - The support uprights are fixed to the casing body, either by being connected thereto integrally, for example by screwing, gluing, welding, etc. or by being formed in one piece with all or part of the casing body.
    - The casing body comprises several parts or subunits fixed to each other, for example of several half-shells and / or wall elements or others coming to overlap, that is to say, to join together to others.
    - the oblong intermediate section of each housing constitutes a guide passage for guiding one of the fingers during his / her movements within the intermediate section.
    - When a user manually actuates the attachment device to move it from the rest position to the attachment position, each finger passes successively from the second end section of the housing, to the intermediate section and to the first end section of the housing in which said finger is inserted, and vice versa.
    - the intermediate section comprises two internal walls arranged face to face and forming guides for the two fingers during their movement between the first and second end sections of the housings.

    - the attachment device comprises two arms, each arm carrying one of the two fingers.
    - The attachment device comprises two arms extending on either side of the cover, that is to say to the right and left of the cover, so as to partially surround it, when the attachment device is in the rest position, that is to say folded.
    - It further comprises at least one stop arranged between the attachment device and the cowling, said attachment device coming into contact with said stop when it is in the rest position, and being spaced due to the presence of said stop at a given non-zero distance from the external surface of the cowling.

    The invention will now be better understood thanks to the following detailed description, given by way of illustration but not limitation, with reference to the appended figures among which:
    FIG. 1 represents a view of the front face of a protective covering according to the invention fitted to a gas cylinder,
    FIG. 2 is a partial view of the rear% of the cowling in FIG. 3,
    - Figure 3 shows a partial view of the rear face of the cowling of Figure 1 with latching device in the latching position,
    - Figures 4 and 5 show a partial side view (in section) of the attachment device in the folded position and in the attachment position,
    FIG. 6 diagrammatically shows a finger cooperating with a housing, and
    - Figure 7 shows schematically the insertion of the two fingers of the fastening device in the two housings of the cowling.
    Figures 1 to 7 show an embodiment of a rigid protective cover 1, commonly called a "cap", arranged around a valve block 3, itself fixed to the neck of a gas cylinder 10. 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 valve block 3 against shocks, whether said valve block 3 is of the type with integrated gas pressure regulator or RDI, or of the type without integrated pressure regulator.
    The protective cowling 1 comprises a cowling body 2 with supporting uprights 5, forming a rigid protective shell around an internal volume dimensioned to receive the valve block 3. The supporting uprights 5 are arranged face to face and project towards the top, as shown in Figure 1.
    H furthermore comprises a carrying handle 4 designed to be taken in hand by an operator, said carrying handle 4 being formed of a rigid material and carried by two support uprights 5 mechanically connecting the body 2 of cowling to the handle of portage 4, that is to say that the support uprights 5 are secured to the carrying handle 4 so as to allow a user to easily transport the hat / tap / bottle assembly.
    The carrying handle 4 is fixed at the distal ends, that is to say the free ends, of the support uprights 5, while the support uprights 5 are, for their part, fixed by or integral with the cowling 1 , via their proximal end.
    It should be noted that the two support uprights 5 can be formed in one piece with the rest of the casing body 2 or, according to another embodiment, constitute independent elements coming to join the casing body 2. Thus, in the embodiment presented in the figures, the support uprights 5 are part of two wall elements 19 fixed to the body 2 of the cover 1, as visible in FIG. 2. More precisely, the two wall elements 19 overlap at least a part of the external surface of the casing body 2, that is to say that they match its external profile, and are joined thereto by screws 15 or the like.
    The body 2 of the cover 1 is typically made of a polymer and / or metal type material, preferably of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA ... Similarly, the support uprights 5 and the two wall elements 19 carrying the support uprights 5 can be formed from a plastic material, like the body of the cowling 1, but also from aluminum alloy or any other metallic material.
    The protective cowling 1 also has openings giving access to the valve block 3 located in the internal volume of the cowling body 2 1, in particular to the outlet fitting 8, to the filling fitting 11, to the pressure outlet fitting 12, with the rotary wheel Ί ...
    More specifically, the valve block 3, typically of the RDI type, comprises a rotary flywheel 7, located on the front face 2a, which can be manipulated by a user to control the gas flow, a gas outlet connector 8 for withdrawing the gas stored in the bottle 10, a pressure gauge 9 to control the gas pressure, a filling connection 11, located on the rear face 2b, used to introduce gas into the bottle 10 when the latter is empty, and a pressurized gas outlet connection 12 located laterally and used to distribute the gas at operating pressure compatible with the downstream application.
    The assembly of the protective cover 1 and its fixing around the valve block carried by the gas cylinder 10 is done by screwing by means of fixing elements, namely screws, bolts or the like.
    Preferably, in the embodiment of the Figures, the body 2 of the cowling is formed of two half-shells which come to join one another, according to a vertical junction plane, and carrying the support uprights 5. In done, the two half-shells sandwich the tap 3 and the neck of the container 10 so as to contain the tap block 3 in their space or internal volume, while the two half-shells forming the body 2 are themselves surrounded by , that is to say sandwiched between, the two wall elements 19 carrying the support uprights 5 surmounted by the carrying handle 4.
    In order to allow the attachment or securing of the bottle 10 / valve block 3 / cover 1 assembly to a support, such as a hospital bed, stretcher bar or the like, the protective cover 1 comprises, on the side from its rear face 2b, an attachment device 6 pivoting about an axis AA, called “axis of rotation”, between:
    a fully folded position, called the "rest" position, that is to say the position adopted by the fastening device 6 when it is stored and positioned in contact or quasi-contact with the cowling 1, and
    - a fully unfolded position called the “hooking” position, that is to say the position adopted by the hooking device 6 when it is completely extended and can be hung on a support, such as a bed bar or similar.
    In Figures 1 and 4, the attachment device 6 is in the rest position, while in Figures 2, 3 and 5, it is in the attachment position, that is to say fully unfolded. These two positions therefore constitute the extreme angular positions that the fastening device 6 can adopt when it pivots around the axis AA. Typically, the pivot angle a 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 °.
    A non-zero spacing can be provided between the fastening device 6 and the cover 1, when the fastening device 6 is in the fully folded position, that is to say "at rest". To do this, one (or more) stopper 13 is arranged between the outer surface of the cowling 1, namely its rear face 2a, and the hooking device 6 so that the latter comes to rest against the stopper 13, when the device attachment 6 is in the "rest" position, and therefore does not become embedded in a cavity or housing of the cowling 1. The stop (s) 13 will therefore stop the angular pivoting stroke of the device attachment 6 when it is folded by the user to move it from its attachment position to its rest position, since the attachment device 6 will meet the stop 13, that is to say come up against it. Thus, there will always remain a minimum spacing between the attachment device 6 and the cover 1 which will then allow the user to easily grasp the attachment device 6 and rotate it to its attachment position. The attachment device 6 is therefore kept voluntary at a minimum distance or spacing from the external surface of the cowling 1. The stop 13 constitutes a sort of protrusion of height H, for example a height H of 1 mm to 15 mm, carried for example by the external surface of the cowling 1 and projecting towards the outside of the cowling 1. The stop 13 is situated opposite the hooking device 6, that is to say in front of the hooking device 6. In other words, the stop (s) 13 is taken “sandwiched” between the hooking device 6 and the cowling.
    In the embodiment of Ligure 3, a single stop 13 is arranged at the base 14 of the cowling 1, namely here on a flange 18 located at the base 14 of the cowling 1. However, according to another mode As an embodiment, several stops 13 can be arranged, for example two or more stops, between the pivoting hooking device 6 and the body 2 of the cowling 1. Similarly, on the Ligures, the stop 13 is fitted on the cowling 1 but according to another embodiment, it is also possible to arrange the stop 13 on the attachment device 6 itself or, according to yet another embodiment, stops 13 can be arranged both on the attachment device 6 and on the casing 2 body 1.
    In general, as illustrated in the Liguria, the attachment device 3 forms a curved three-dimensional structure which surrounds the body 2 of the cover, when the attachment device 6 is in the rest position.
    More specifically, the curved three-dimensional structure forming the attachment device 6 comprises two arms, namely a right arm 6a and a left arm 6b, coming to take the body 2 of the rollover substantially "sandwiched", when the attachment device 6 is in the rest position. Each of the arms 6a, 6b carries a fixing notch 16 used for hooking the assembly to a support, such as a hospital bed bar or the like. Each fixing notch 16 has an arcuate shape, for example shaped as an arc of a circle, as illustrated in Ligure 2, so as to best match the shape of a tubular bar for a bed, stretcher, wheelchair or other.
    In the storage position, the attachment device 6 is positioned around the casing body 2 so as to minimize the overall size of the enclosure 1, when the attachment device 3 is folded up as in FIG. 2. When the structure three-dimensional forming the attachment device 6 is folded, it projects externally but without increasing the overall size of the cowling 1. The attachment device 6 then comes into contact or almost contact the stop 13 by covering the stop 13 .
    The attachment device 6 therefore comprises a free downstream end carrying the arms 6a, 6b, and an upstream end which is fixed in pivoting (axis of rotation AA) to the cowling 1, preferably to the support uprights 5 of the cowling 1. A opening may be provided in the wall of the casing body 2 1 to allow and / or facilitate the pivoting of the attachment device 6 from its rest position to that of attachment, or vice versa.
    The attachment device 6 can be formed from plastic, metal or a combination of the two.
    Furthermore, in an alternative embodiment, the three-dimensional structure constituting the attachment device 6 comprises a central opening 17, revealing the filling connection 11, when the attachment device 6 is in the rest position, that is to say ie folded and in contact with the stop 13. This allows the user to fill the bottle 10 with fresh gas, without having to unfold the attachment device 6, that is to say leaving the device d 'hooking 6 in its rest position.
    According to the present invention, in order to ensure that the fastening device 6 is kept in a stable position, when it is unfolded or folded, and an easy passage from one position to the other, without causing significant complexification of the rollover, two fingers D are provided, that is to say two protruding expansions, carried by said attachment device 6 cooperating with two housings L carried by the cover 1, preferably by the support uprights 5 of the cover
    1. For example, the housings L can be arranged in the casing body itself, in expansions of walls integral with said casing body 2, in the support uprights 5, or in elements fixed to or integral with said support uprights 5 or the casing body 2.
    The housings L have a particular shape, as explained below.
    As illustrated in FIGS. 4, 5 and 7, the pivoting, that is to say the angular indexing, of the attachment device 6 relative to the cover 1 is ensured by two fingers D carried by the attachment device 6. These two fingers D projecting away from the hooking device 6 and are oriented in opposite directions relative to each other. They are arranged on an axis BB parallel to the axis of rotation AA, said axis BB, also called 'movable axis', is pivotally movable, that is to say in rotation relative to the axis AA is it is fixed, ie immobile.
    As detailed in Ligure 6, the two fingers D each cooperating with one of the two housings L carried for example by the support uprights 5 of cowling 1, or for example arranged in the body 2 of cowling, each finger D coming from insert into one of said housings L, each finger D being movable within one of said housings L.
    Each housing L is configured to present at least 3 successive sections SI, S2, S3 comprising a first end section SI and a second end section S2 connected to each other by an intermediate section S3 which forms a sort guide lane for each finger D, when it moves in this intermediate section S3.
    The first and second end sections S1, S2 have an internal profile of generally semi-circular shape, while the intermediate section S 3 has a generally oblong, that is to say elongated, shape.
    Each finger D is positioned in the first end section SI of the housing L into which it is inserted, when the hooking device 6 is in the hooking position and, conversely, in the second end section S2 of this housing, when the attachment device 6 is in the rest position.
    It can be seen in Figures 4, 5 and 6 that the oblong intermediate section S3 comprises two internal walls PI, P2 arranged face to face which form guides for the two fingers D during their movement in the intermediate section S3, during their passage from the first to the second end section S1, S2 of the housings L, or vice versa. The two internal walls PI, P2 arranged face to face, are curved.
    In order to ensure that the stable position is maintained, the first and second end sections S1, S2 are separated from the intermediate section S3 by wall restrictions RI, R2 projecting radially towards the interior of the intermediate section S3, as can be seen in Figures 4 and 5. These wall restrictions RI, R2 somehow form stops serving to create a hard point and to properly hold the fingers D, when they are positioned in the first and second end sections SI, S2, that is to say in the rest or latching position.
    The passage of the wall restrictions RI, R2 by the fingers D is facilitated by an axial slot L arranged at the free end EL of the fingers D, as illustrated in Ligure 7. Preferably, the slots E are arranged in a part of the fingers D made of an elastically deformable material, for example a polymer.
    This slit E separates each finger D into two half-fingers. This structure allows the fingers D to deform elastically and locally when passing the wall restrictions RI, R2 since, when the fingers D pass between the wall restrictions RI, R2, these act mechanically on the two half-fingers and the force to get closer to each other by filling the space between them, that is to say the slot E. The diameter of the fingers D is therefore reduced at the free ends EL thus allowing the passage of the fingers D between the wall restrictions RI, R2, including if the diameter of the fingers D at the said free ends EL is, before deformation, slightly greater than the passage P existing between the said wall restrictions RI, R2.
    This elastic deformation of the fingers also prevents premature wear of the wall restrictions RI, R2 and of the fingers D.
    However, the width L of the wall restrictions RI, R2 is preferably slightly greater than that of the cylindrical sections at the level of said free ends 5 EL of the fingers D to allow their passage through said wall restrictions RI, R2. In this case, the F slots are not necessary.
    Preferably, the width of the wall restrictions RI, R2 is between 0.5 and 2 mm.
    Advantageously, the first and second end sections S1, S2 have an internal wall of semi-circular shape SC opening onto the intermediate section S3, through the wall restrictions RI, R2. Preferably, the clearance between the radius Ro of the first and second end sections SI, S2 of semi-circular shape and the radius of D is between 0.1 and 1 mm.
    A gas cylinder fitted with a cover according to the invention is particularly well suited for the storage and distribution of pressurized gas, in particular medical gas, in particular a gas chosen from oxygen, air, N2O / O2, He / Ch and NO / nitrogen.
