    [0001] The present invention relates to a device for supplying gas. The invention more particularly relates to a gas supply device comprising a frame housing a set of pressurized fluid bottles connected to a fluid circuit for drawing off and filling the bottles, the support frame comprising a lower base on which the bottles lie vertically and a set of uprights and transverse beams defining a cage of parallelepiped general shape for lateral support of the bottles arranged in several contiguous rows. The invention relates in particular to gas supply devices sometimes called "frames". Such a device is described for example in the documents DE20103682U1, GB2007348 A1 or DE102011014065 A1. Such devices generally use a bundle of cylinders storing gas at high pressures, for example 200 bar, 300 bar or beyond.
    [0002] These devices must satisfy various constraints and often antagonistic for example: a structure whose use is ergonomic and the least massive possible while providing sufficient protection of the bottles in case of shock. The structure must in particular be able to support the weight of all the bottles during slinging or craning. During such a lifting operation the frame is subjected to a traction force generated between the upper attachment points (slinging rings at the four upper corners or central ring) and the bottom of the frame on which the bottles rest. The structure of these frames must thus be relatively rigid. Such rigidity of the frame requires to design bottles and frame frame relatively robust to absorb the energy transmitted by the frame in case of fall of the whole. Indeed, the rupture of some parts of the device can lead to relatively serious accidents. An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above and in particular to provide a device having good impact resistance. To this end, the device according to the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that it comprises at least one rigid reinforcing bar of the frame arranged between two rows. contiguous bottles, said at least one reinforcing bar resting simultaneously on the upper surface of the bottles of two rows of adjacent bottles, the reinforcing bar comprising two ends rigidly connected respectively to two opposite faces of the frame.
    [0003] Furthermore, embodiments of the invention may include one or more of the following features: the at least one reinforcing bar bears on the bottles and generates a vertical force on the bottles in the direction of the base, the two ends of the reinforcing bar are rigidly connected respectively to two transverse frame beams located respectively on two opposite faces of the frame, the ends of the at least one reinforcing bar are rigidly connected to the transverse beams via at least one linkage axis such as a pin disposed in a vertical plane parallel to the plane of a lateral face of the frame, the connection axis or pins comprise a mechanism such as a screw / tapping system for adjusting the vertical position of the frame; the bar relative to the transverse beam to which it is connected to adjust the support force of the bar on the bottles, 20 - the dispo sitif comprises intermediate corner reinforcing members respectively arranged at the level of the links between firstly the ends of the transverse beams connected to the at least one reinforcing bar and, secondly, the adjacent amounts concerned, the reinforcing members intermediate wedges being rigid and comprising two ends rigidly connected respectively to a transverse beam and to the adjacent post, the transverse beams connected to the at least one reinforcing bar are located in the upper half of the frame and preferably in the upper third. of the frame, - the upper end of the bottles has a convex warhead shape and in that the at least one reinforcement bar rests on the convex portion of the bottles, - the bottles located on the periphery of the group of bottles are in lateral support on the uprights and / or transverse beams of the frame, - the device comprises upper corner fort disposed respectively at the level of the links between firstly the ends of the transverse beams defining the upper end of the frame and, secondly, the adjacent amounts concerned, the upper reinforcing members being rigid and comprising two ends rigidly connected respectively to a transverse beam and to the adjacent upright, the device comprises at least three rows of at least three bottles housed in the frame and two parallel reinforcement bars resting simultaneously on the upper surface of two rows of adjacent bottles; the device comprises four rows of four bottles housed in the frame and two parallel reinforcing bars resting simultaneously on the upper surface of two distinct pairs of rows of adjacent bottles; the device comprises a face delimited by uprights having a vertical length less than the length of vertical uprights of the opposite face, that is to say one face of the frame at a height greater than the height of its opposite, - the at least one reinforcement bar is parallel to said frame faces having different heights, the frame comprises upper transverse beams located at the upper end of the frame and respectively connecting the uprights two to two, the upper transverse beams connecting the different height uprights are inclined and / or curved, the frame comprises a central post whose lower end is integral with the central part of the base and whose upper end comprises a ring for handling the frame projecting beyond the parallelepipedal volume of the cage, - at least a part of one at least one of the faces of the frame (lateral or upper faces) comprises a grid and / or a solid partition, the frame comprises intermediate transverse beams and EXTERIORFEATURES located at mid-height, respectively, and lower frame part and respectively connecting the two uprights to two.
    [0004] The invention may also relate to any alternative device or method comprising any combination of the above or below features. Other features and advantages will appear on reading the following description, with reference to the figures in which: - Figure 1 shows a perspective view, schematic and partial, illustrating an exemplary embodiment of a part of the frame in partly disassembled configuration (without bottles or reinforcing bar (s)); - FIG. 2 represents a schematic and partial perspective view of a detail of the upper part of the device of FIG. 1 in use configuration; 3 represents a top view of the device of FIG. 2, FIG. 4 represents a side view of the upper part of the device of FIG. 2, FIG. 5 represents a side view, schematic and partial. FIG. of the upper part of the device of FIG. 2 in a state deformed by a shock. The gas supply device 1 partially illustrated in FIG. 1 and in FIGS. 2 to 4 conventionally comprises a support frame 2 comprising, for example, a metal frame of generally parallelepipedal shape housing a plurality of pressurized fluid bottles 3.
    [0005] For example, the bottles 3 are arranged in a beam vertically on a base 34. The bottles 3 are arranged according to several rows of contiguous bottles (four rows of four bottles 3 in the nonlimiting example illustrated in the figures). The upper part of each bottle 3 comprises an orifice connected to a fluidic circuit 4 to ensure the withdrawal or filling of the bottles 3. For example, the circuit 4, 5 has a first connection end connected to the bottles 3 via a first valve The circuit may include a separate second connection end connected to the orifices of the bottles 3 via a second isolation valve and a pressure regulator. The frame 2 comprises a set of four vertical uprights whose lower ends are respectively connected to the four corners of the square 34 (or parallelepiped) base.
    [0006] The vertical uprights may have a U-shaped or parallelepipedal section and may be oriented to present a planar surface at the vertical edges of the frame 2. That is, the face of the uprights 30 facing each other. bottles 3 is oriented at approximately 45 degrees to the sides of the parallelepiped base 34. That is to say that a side of greater width of the parallelepipedal section of the upright 30 is oriented towards the center of the frame 2. The frame 2 also comprises horizontal transverse beams 31, 32, 33 delimiting the lateral faces of the frame. a cage of parallelepipedal general shape for the vertical holding of the bottles 3 (see Figure 2 or 3). In particular, the frame 2 may comprise four lower transverse beams 33, four intermediate transverse beams 31 and four upper transverse beams 32. As can be seen in FIG. 3, where appropriate two pairs of rows of four bottles 3 can be separated by a partition or one or more transverse beams located inside the frame 2. In this case, the bottles adjacent to this partition 13 are preferably in contact with the latter. The frame 2 may comprise a central pole 37 whose lower end is secured to the central portion of the base 34 and whose upper end has a ring 39 for handling the frame projecting beyond the parallelepipedal volume of the cage. At least a portion of at least one of the faces of the frame (lateral or upper faces) may be perforated at least partially by a grid and / or a solid partition fixed to the uprights 30 and transverse beams 31, 32, 33. The frame 2 may include on one of its lateral faces called "front face" an interface panel having at least one opening and in particular at least one access to the circuit 4, 5 and in particular to circuit members (fluid connector (s) (s) 11, pressure gauge 12).
    [0007] According to an advantageous feature, the device comprises at least one and, in this example, two rigid reinforcement bars 6 of the frame 2. The reinforcement bars 6 are arranged between two rows of adjacent bottles 3. Each reinforcing bar 6 rests simultaneously on the upper surface of the bottles 3 of two rows of adjacent bottles 3. Each reinforcing bar 6 comprising two ends rigidly connected respectively to two transverse beams 31 of the frame situated respectively on two opposite faces of the frame 2.
    [0008] Preferably, the upper end of the bottles 3 has a convex ogival shape and the reinforcement bars 6 rest on the convex portion of the bottles 3. As illustrated, the bars 6 may be tubular and for example of circular section. The bars may be made of metallic steel material or any other suitable material (preferably the same material as that constituting the frame). Due to the support on two rows of adjacent bottles and / or bottles of higher shape, the reinforcement bars 6 make it possible to generate a force of holding bottles 3 with a vertical component (towards the base 34) and a component transverse (helping to press the peripheral bottles 3 against the side faces of the frame 2). The reinforcement bars 6 can be positioned in abutment on the bottles 3 to generate a vertical force on the bottles 3 in the direction of the base. This contributes to maintaining the bottles 3 against the sheet of the base 34 and against the uprights 30 or transverse beams 31, 32, 33. Moreover, this achieves a distribution of forces in the frame which allows to dissipate some of the energy a shock by sparing at least part of the bottles 3. In effect, this structure defines two parts in the frame 2: a first part located between the transverse beams 31 connected to the reinforcement bars 6 and the base 34 and a second part located between the transverse beams 31 connected to the reinforcement bars 6 and the upper end of the frame 2. The first part is relatively more rigid and non-deformable due to the cohesion between the bottles 3 held against the frame 2 via the reinforcement bars 6 .
    [0009] The second part, which is not leaned against the bottles 3 (part located above the bottles 3), is relatively less rigid and more deformable in case of shock. In particular, in case of fall of the frame 2 on its vertical end, the second part can absorb energy by deforming. The vertical uprights may in particular form zones deforming in flexion above the transverse beams 31 connected to the reinforcement bars 6 (see for example FIG. 5) while part of the forces are transmitted in the lower rigid part. via the bars 6, the bottles ...
    [0010] This architecture makes it possible to absorb and distribute forces advantageously with respect to known structures. This allows in particular to promote a natural deformation towards the inside of the frame 2 to accompany the general deformation of the frame. This allows a bending of the uprights 30 and the gas circuit thus limiting the risk of bending / tearing in case of displacement of the valves of the circuit 4, 5). The fluid circuit 4, 5 is advantageously housed in the deformable part of the frame 2 and can therefore preferably be designed so as to deform in the event of contact with the frame 2 as a result of excessive deformation or in case of displacement of bottles 3 in case of breakage of their fixings to the frame 2.
    [0011] For this purpose, the circuit may comprise a common collector portion comprising a closed loop (relatively more rigid), and a relatively more flexible portion comprising more flexible lines 4 connecting the bottles 3 to the closed loop 5. As illustrated, the ends of the reinforcement bars 6 can be rigidly connected to the transverse beams 31 via at least one connecting axis 7 such as a stud disposed in a vertical plane parallel to the plane of a lateral face of the frame 2. the connecting pins 7 may include a mechanism such as a screw / tapping system (with nut if necessary). Preferably, this mechanism allows the adjustment of the vertical position of the bar 6 relative to the transverse beam 31 to which it is connected to adjust the vertical support force of the bar 6 on the bottles. The intermediate transverse beams 31 to which the reinforcement bars 6 are connected may be located at half height of the frame 2 and preferably about two-thirds or three-quarters of the total height of the frame 2. As illustrated, the frame 2 may comprise in addition to the intermediate corner reinforcing members 9 arranged respectively at the level of the connections between firstly the ends of the transverse beams 31 connected to the reinforcement bars 6 and, secondly, the adjacent uprights 30 concerned. The intermediate corner reinforcement members 9 are rigid and have two rigidly connected ends (welding or riveting or otherwise) respectively to a transverse beam 31 and to the adjacent stud. Similarly, the frame 2 may comprise upper corner reinforcing members 8 disposed respectively at the level of the connections between on the one hand the ends of the transverse beams 32 delimiting the upper end of the frame 2 and, on the other hand, the uprights 30 adjacent concerned. As before, these upper corner reinforcing members 8 are rigid and comprise two ends rigidly connected respectively to a transverse beam 32 and the adjacent post. For example, the corner reinforcing members 8, 9 have a square shape. The structure according to the invention thus makes it possible to clamp and flatten (vertically and laterally) a set of bottles in a frame 2. The structure thus forms a chain of direct transmission of effort between the frame 2 and the cylindrical portion of the bottles 3 The upper ends of the four uprights 30 situated above the reinforcement bars 6 form four preferred flexion / folding / twisting zones capable of dissipating energy in the event of a fall of the frame 2. These flexure zones may in particular be defined by the position and the dimension (including the thickness) members 8, 9 of corner reinforcement connecting the uprights 30 and the beams 31, 32 transverse. The deformation of this portion is a function of the energy generated by the impact during the fall of the frame 2, the intrinsic rigidity of the deformation zone of the frame 2 (thickness and shape of the uprights 30, beams 31, 32 and corner reinforcing members 8, 9). The maximum amplitude of the deformation can be calculated so that the deformation zone never encounters the pressure sensitive members of the circuit 4, 5. Moreover, this can be shaped to ensure that the fastening system (reinforcement bar 6 and fixing axis 7) does not suffer from the deformation of the uprights 30 in order to guarantee maximum cohesion of the bottles 3 in the frame 2.
    [0012] For this purpose, and as described above, the vertical uprights are preferably positioned at 45 ° with respect to the plane of side faces of the frame 2. Several levels of deformation can occur depending on the potential energy stored during the fall of the frame 2. The potential energy of the shock depends in particular on the mass of the frame 2 (and therefore on the quantity of on-board gas, the mass of the overall structure being constant), the speed of fall of the frame and the the intrinsic damping of the soil on which the frame falls. Different possible deformation levels are detailed below in case of impact on an upper corner of the frame 2. These expected deformations are listed in ascending order of the impact energy. - partial crushing of the outer face of the tubular profile of the upright 30, - total crushing of the tubular profile of the upright 30, 15 - torsion of the upright 30 (until its face becomes, where appropriate, parallel to one face of the frame 2 ), - bending of the amount 30 limited by the presence of the elements 8, 9 of corner reinforcement allowing more homogeneous distribution of stresses on the whole structure, 20 Of course this order is given as an indication and the order and the amplitude of the deformation levels can be modified according to the conditions. The presence of curved lateral beams 32 on the upper part of the frame 2 can make it possible to follow the bending of the vertical upright impacted by the fall without transmitting excessive force on the opposite upright. As illustrated, a so-called "rear" side face of the frame 2 may be delimited by posts 30 having a length (height) greater than the length (height) of the uprights 30 of the opposite "front" face 35. The upper transverse beams 32 connecting a post 30 to an upright 30 can thus be rectilinear and inclined downward from the rear to the front and / or curved with the concavity oriented towards the base 34.
    [0013] The upper geometry of the frame 2 makes it possible to improve the impact resistance of the frame as described above without unduly penalizing the mass, the cost or the complexity of the frame 2. Indeed, according to the invention, the deformation and holding the impact of the frames is improved over the prior art, without the need to provide protection members or shock absorption on the periphery of the frame. This partially deformable structure allows the frame itself to absorb some of the impact energy. This makes it possible to transmit to the bottles and their fasteners only part of the deceleration of the frame.
    [0014] This preserves the gaseous circuit 4, 5 of the frame avoiding excessive deformation of the latter due to the relative displacement of the bottles .3 relative to each other. This substantially reduces the risk of gas leakage under high pressure.
    [0015] The deformation of the frame 2 obtained also avoids the shock of the frame 2 against pressurized gas control members (valves type, expansion valves, etc. ..) thus maintaining the integrity of the gas circuit under high pressure. Thus, while being simple in structure and can costly, the device 20 has many advantages over known systems. Of course, other modifications are possible. Thus, the number and orientation of the reinforcement bars 6 can be changed. For example, the reinforcing bars may be arranged perpendicular to the front face of frame 2.
