Description

The present invention relates to the general field of outdoor cabinets intended to contain electronic, electrical or telecommunication equipment.

The invention more specifically relates to an outdoor cabinet intended to contain electronic, electrical or telecommunication equipment and comprising an outer envelope delimiting a compartment intended to accommodate said equipment, said cabinet also comprising at least one first shading screen for being attached to the outer casing to generate a shadow thereon, said cabinet further comprising a fastening system adapted to removably attach the first shading screen to said outer casing so that said first shading screen is kept facing and away from the outer casing to interpose and a first air gap between the outer casing and the first shading screen.

The invention also relates to a method of transforming an outdoor cabinet intended to contain electronic, electrical or telecommunication equipment and comprising an outer envelope delimiting a compartment intended to receive said equipment, in which at least one first screen is reported. shading on the outer casing to generate a shadow thereon by a fastening system adapted to releasably attach the first shading screen to said outer casing so that said first shading screen is maintained facing and away from the outer casing to Interpose and a first air gap between the outer casing and the first shading screen. Outdoor cabinets intended to contain electronic, electrical or telecommunication equipment are known as such and are generally formed of a parallelepipedal housing provided with two opposite side walls, a back wall, a roof , and a front access opening closed by an access door that can be locked to protect the material inside the housing. Such a cabinet is usually made of metal or plastic in order to 813767 / FR resist the nuisance likely to be caused by its positioning outdoors, such as weather or vandalism. Such cabinets may be required to enclose heat-sensitive equipment, as is the case for electronic components or for power components. In addition, such equipment, especially when it is about "active" material, that is to say a material powered to operate, is likely to produce heat by itself. A large amount of heat is also carried by the solar radiation projected on the cabinet when it is positioned in a place exposed to such radiation, which is common in practice. Thus, it is necessary to cool the air inside the cabinet to ensure the integrity and proper operation of the active material it contains. To facilitate this cooling, it is also known to reduce the influence of solar rays, which play a major role in the amount of heat present in the cabinet. For this, it is known to use shading panels to protect such cabinets solar radiation. There is thus known a cabinet using different shading panels attached to the side walls and back of the cabinet, as well as the front door, thus trapping a layer of air around the cabinet. Despite the presence of openings formed by grids through the shading panels, the air layer to heat up in the interstitial space, making it necessary to resort to a cooling system to cool the cabinet. The presence of the grids arranged on the shading panels also alters the shading provided by the panels at said grids, since the latter less effectively stop the sun's rays. The shading panels are also of relatively complex design and construction, with the implementation of inserts of the type grids and brackets. Cabinets are also known which use grid-free side shading panels, but with vertical fins that come into contact with the wall of the cabinet to form separate vertical channels each containing an independent air gap. . Such a design, however, is not optimal in terms of thermal protection of the cabinet. In addition, the shading panels implemented on this cabinet are attached to the body of B13767 / FR the cabinet by screwing to the brackets, each of which receives two panels at a time, the edge of the first covering the edge of the second at said screw tab. For this reason, it is impossible to disassemble each panel of the cabinet separately, the disassembly of the panel whose edge is covered by the edge of the other panel attached above requiring the disassembly of the latter in the first place. In addition, the screws are accessible from outside the cabinet, which increases the risk of vandalism by dismantling and theft of the panels thus making the cabinet vulnerable to sunlight. The objects assigned to the invention are therefore intended to remedy the disadvantages of the prior art mentioned above and to propose a new outdoor cabinet and a new method of transforming an outdoor cabinet, which while being Extremely simple design effectively limits the warming of the contents of the cabinet under the effect of solar radiation. Another object of the invention is to provide a new outdoor cabinet 15 having improved thermal properties without resorting to additional energy input. Another object of the invention is to provide a new outdoor cabinet which while being easy to use is particularly safe and resistant to possible unauthorized disassembly attempts. Another object of the invention is to provide a new outdoor cabinet which, while being strong and safe, has sun protection means which can be easily mounted or dismantled. Another object of the invention is to propose a new method of transforming an outdoor cabinet making it easy to transform a cabinet intended to contain passive equipment into a cabinet intended to contain active equipment and vice versa. The objects assigned to the invention are achieved by means of an external cabinet intended to contain electronic, electrical or telecommunication equipment and B13767 / FR comprising an outer envelope delimiting a compartment intended to receive said material, said cabinet also comprising at least a first shading screen to be attached to the outer casing to generate shadow thereon, said cabinet further comprising a fastening system adapted to removably attach the first shading screen to said outer casing so that said first shading screen is kept facing and away from the outer casing to thereby interpose a first air gap between the outer casing and the first shading screen, characterized in that said first air space opens directly into the air along the majority of at least its perimeter. The objects assigned to the invention are also achieved by means of a method of transforming an outdoor cabinet intended to contain electronic, electrical or telecommunication equipment and comprising an outer envelope delimiting a compartment intended to accommodate said hardware, wherein at least one first shading screen is reported on the outer envelope to generate a shadow thereon by a fastening system adapted to removably attach the first shading screen to said envelope. so that said first shading screen is kept facing and away from the outer casing to thereby interpose a first air gap between the outer casing and the first shading screen, the method being characterized in that said first air space opens directly into the air along the majority of at least its perimeter.

Within the meaning of the invention is understood by "outdoor cabinet" a piece of furniture, for example 20 urban furniture like cupboard, trunk or cabinet, designed to be implemented over a longer or shorter period in an open environment for example on the public road, in the street, in the nature, on a roof of a building or in the garden of a house. The outdoor cabinet 1 can also be placed in semi-enclosed spaces such as a basement, a subway, a factory, a shed or a shelter. Naturally, this furniture suitable for outdoor can also be placed indoors. 813767 / FR According to the invention, the outer cabinet 1 comprises an outer casing 3 defining a compartment 4 for receiving electronic or electrical equipment or telecommunications. The cabinet 1 is thus intended to enclose said material in an inner chamber to protect it from external nuisances such as bad weather (rain, temperature variations, solar radiation, frost, etc.), dust and dirt, pests (insects, animals, vegetation, parasites, etc.), shocks and vandalism (car accidents, deliberate damage, etc.) and theft. The outer casing 4 then makes it possible to isolate the material from the outside, and makes it preferably invisible from the outside of the cabinet 1, thanks to the implementation of an opaque outer envelope 3. The cabinet 1 thus offers a protective shell to its contents, and provides an interior environment conducive to its operation and maintenance in the state. The cabinet 1 further protects the people and external elements of its own content, which can present risks, for example electrical, chemical, toxic, fire, or radiation. The outer envelope 3 preferably comprises one or more entry (s) access that can be condemned (at least temporarily) by one or more door (s), hatch (s), or flap (s). Preferably, the door (s) is (are) provided with locking means, such as a lock, a padlock or a lock. The outer shell 3 may also include gates or sidewalls 9, shutters, a roof 10 and a floor (as illustrated in FIGS. 1 and 2). The outer casing 3 is sufficiently solid, rigid, opaque or resistant to ensure separation between the contents of the compartment 4 and the outside of the cabinet 1. For example the outer casing 3 is made of a metallic material, such as than steel or aluminum. Preferably, the cabinet 1 is intended to contain electronic, electrical or telecommunications equipment, for example for managing, and / or transmitting and / or distributing telecommunication data, or electrical energy. It is therefore preferably connected to a network or to external communication elements to the cabinet 1. The equipment intended to be contained in the cabinet 1 may, for example, comprise passive equipment, that is, that is to say not requiring power supply to operate, such as cables, connectors, optical fibers. The equipment contained in the cabinet 1 can, on the contrary, be active, thus requiring a power supply to operate, preferably an electrical one, the equipment comprising for example in this case an amplifier, a distributor, a differentiator, a transmitter, a router, a bridge, a repeater, a concentrator, or a switch, this list is of course not exhaustive. The cabinet 1 preferably allows to contain and protect the equipment from the climatic conditions, in particular to avoid overheating of the equipment, especially if it is active equipment. Indeed, the electronic, electrical or telecommunication equipment, especially when it is active equipment, needs to be maintained in a temperature range adapted to its operation and storage, at the risk of damaging it. For this, the compartment 4 of the cabinet 1 is likely to provide a temperate environment, air-conditioned, and above all independent of changes in outside temperatures or the influence of certain elements such as sunlight. Equipment, especially when it comes to active equipment, can produce heat harmful to its own operation. Thus the heat preferably coming from the inside and the outside of the cabinet 1 must be evacuated. For this purpose, said cabinet 1 comprises at least a first shading screen 5a intended to be attached to the outer casing 3 to generate a shadow on the latter.

The first shading screen 5a is preferably formed of a curved or planar surface. It is opaque or at least not sufficiently transparent to interrupt and not to transmit the solar rays projected on it. For this, the first shading screen 5a may for example absorb or reflect said rays. It may be made of the same material as the cabinet or a different material particularly adapted to its role of protection vis-à-vis the spokes, and adapted to an external environment as described above, preferably a metallic material B / 3767 / FR (for example an alloy of steel or aluminum) or plastic. The first shading screen 5a obstructing the light, it thus projects a shadow on the outer casing 3, that is to say, it prevents the radiation from reaching directly to said outer casing 3. the amount of heat transmitted by radiation to the cabinet 1 is limited by the first shading screen 5a. According to the invention, the first shading screen 5a is kept opposite and at a distance from the outer casing 3. The first shading screen 5a is thus disposed near the outer casing 3, preferably without direct physical contact. with this one. Preferably, the shape of the first shading screen 5a matches that of the outer envelope 3, so that the first shading screen 5a is preferably disposed predominantly, or even at any point, substantially equidistant from said outer envelope 3. In this way, an interstitial space 18 is created between the outer envelope 3 and the first shading screen 5a, which is substantially in the shadow of said first shading screen 5a (as illustrated in FIGS. , 5 and 6). Preferably, the first shading screen 5a comprises a panel 15 (as illustrated in FIGS. 3 and 4). The panel 15 may be for example of flat and rectangular shape, and have two lateral sides 19, an upper side 20 and a lower side 21. It also has an illuminated face 22, turned towards the outside of the cabinet 1, and a face to the shadow 23 turned on the side of the outer casing 3. It can be made for example in a metal sheet. Preferably, the first shading screen 5a comprises at least one first lateral falling edge 16a which extends from the panel 15 and is oriented at an angle of between 300 and 60 °, preferably 45 °, with respect to said panel 15 The first lateral flange 16a thus forms an inclined flange which laterally extends said panel 15. The first lateral flange 16a is preferably disposed on one of the two lateral sides 19 (as illustrated in FIGS. panel 15 and preferably forms a piece integral with said panel 15. It can be for example i3 / 3767 / FR the result of a thermal bending of the metal sheet forming the panel 15. The first side flop 16a is preferably oriented toward the outer casing 3, the side of the face to the shadow 23. It improves the rigidity of the panel 15. It also reduces the risk of injury to a third party, in making for example the edge of one of the non-cutting side sides 19, or by changing the orientation of the cutting portion, or by breaking the angles of the panel 15. Preferably, the first shading screen 5a also includes a second edge 16b which extends from the panel 15 symmetrically with respect to the first lateral fall edge 16a. Preferably, the first and second lateral falling edges 16a, 16b each extend on an opposite lateral side 19 of said panel 15. According to the invention, the first shading screen 5a is kept opposite and at a distance from the envelope external 3 to thereby interpose a first air gap 7a between said outer envelope and said first shading screen 5a, said first air gap 7a thus being positioned within the interstitial space 18.

In other words, the interstitial space 18 allows the presence of an air thickness interposed between the first shading screen 5a and the outer envelope 3. This first air space 7a thus forms an insulating layer located in the shade of the first shading screen 5a, so that it is not heated directly by the solar radiation, and it is rather cold enough to help cool the cabinet 1 or at least to limit the heating of the interior of the latter. According to the invention, the first air knife 7a opens directly to the air along the majority of at least its perimeter, and preferably substantially all or almost all of its perimeter. Thanks to this technical arrangement, the first air gap 7a can thus freely circulate between the interstitial space 18 and the outer periphery of the first shading screen 5a, substantially no obstacle being disposed on the periphery of said first air knife 7a. The first air gap 7a is thus free of stress and can be naturally renewed very quickly and efficiently. This free circulation allows an excellent heat exchange between the interstitial space 18 and the outside, which el3767 / FR substantially avoids any significant heating of the first air space 7a. The majority of the perimeter of the first air gap 7a opening directly to the outside, the effectiveness of the thermal insulation properties of the first shading screen 5a are improved. In addition the free movement of the first air gap 7a gives it the ability to help limit the heating of the cabinet 1 and the material it contains by cooling naturally in the open air. According to the invention, the cabinet 1 further comprises a fastening system 6 designed to removably attach the first shading screen 5a to said outer envelope 3.

The fastening system 6 keeps the first shading screen 5a facing and away from the outer casing 3 by cooperating with the latter. It may comprise, for example, lugs 24 distributed on the first shading screen 5a connecting the outer envelope 3 to the shadow face 23, the said tabs 24 being locally orthogonal to the first shading screen 5a and / or to the outer casing 3 (for example to a side wall 9). The fastening system 6 preferably affixes the first shading screen 5a to a first side wall 9a belonging to the outer casing 3. The fastening provided by the fastening system 6 is removable, that is to say to say that it allows to attach or detach at leisure the first shading screen 5a to / from the outer casing 3 in order to obtain either a cabinet 1 bare, devoid of sunscreen in the absence of said first screen shading 5a, or on the contrary a wardrobe 1 dressed, equipped with said first shading screen 5a. The removal of the first shading screen 5a does not alter the rest of the properties of the cabinet, it remains then especially absolutely intact and still allowing to enclose the material sufficiently tight in the compartment 4. The first screen 5a shading is removably mounted, but also so as to withstand the external environment of the cabinet 1, for example that the holding of the first shading screen 5a weatherproof, or shock objects such as vehicles. In addition, it preferably has a locking system detailed below, so that said first shading screen 5a is difficult to dismantle by an unauthorized third party, but easily removable by an authorized user once the system of 13137671FR lock unlocked. In this way, the first shading screen 5a is mounted on the outer casing 3 removably, but resistant and adapted to the external environment. Preferably, the fastening system 6 is integral with the first shading screen 5a.

The tabs 24 are, for example, welded or riveted to the panel 15 of the first shading screen 5a. Preferably, the outer casing 3 comprises an attachment device 8, to which the fastening system 6 is designed to hang. The attachment device 8 secured to the outer casing 3 thus cooperates with the fastening system 6 by hooking it to the attachment device 8, to form a reversible mechanical connection. Preferably, the outer envelope 3 comprises a roof 10 and a first side wall 9a. The outer casing 3 is thus preferably of generally parallelepipedal shape, its faces being then formed by side walls 9, the first substantially plane side wall 9a. The roof 10 which is preferably also substantially flat, horizontal and rectangular, then forms the top of the outer casing 3. However, the invention is not limited to such a form of cabinet 1, the outer casing 3 and that the side walls 9 can adopt more complex shapes, for example curved, angular, the side walls 9 and / or the roof 10 may further be provided with additional equipment, such as fins, openings or windows. Preferably, the first side wall 9a comprises an upper edge 11 forming part of the hooking device 8, the fastening system 6 being designed to hook onto said upper edge 11. B13767 / FR Thus, for example, a part the fastening system 6 is distributed on the top of the first shading screen 5a so that it aligns with the upper edge 11 and can be hung there. Preferably, the first side wall 9a and said roof 10 are designed to move between two relative positions: - a disassembled position, in which the roof 10 and the first side wall 9a can be placed so that the fastening system 6 can be hooked to or removed from said upper edge 11, a mounted position, in which the roof 10 is fixed to the first side wall 9a so as to limit the displacement of the fastening system 6 relative to the upper edge 11 so that the stall of said fastening system 6 of said upper edge is made impossible. The disassembled position thus makes it possible to fix or detach the first shading screen 5a to the outer casing 3 in a perfectly removable manner, requiring little effort on the part of the user. The disassembled position thus corresponds to an unlocked position. The mounted position corresponds on the contrary to a locked position, the first shading screen 5a can no longer be detached from the outer casing 3. Preferably, the attachment of the roof 10 to the first side wall 9a is done through a system anti-theft device such as a padlock or a lock. More preferably, the attachment of said roof 10 to the first side wall 9a is made from the inside of the compartment 4 by screwing, said compartment 4 being secured by the closure of a front door 25 of the cabinet, which the one can for example lock up. Preferably, the fastening system 6 comprises a first hook 12a intended to cooperate with the upper edge 11 and a second hook 12b intended to cooperate with a catch 17 forming part of the fastening device 8, and arranged on the first wall lateral 9a. The first and second hooks 12a, 12b are for example each attached to a tab 24 making them integral with the panel 15. They comprise a U-shaped slot in which the edge of the wall is intended to be inserted. . This slot forms the seat 28 of said first and second hooks 12a, 12b. This seat 28 is attached on one side to a base 29, and on the other side to a latching nose 27 (as shown in Figures 3 to 6). The first and second hooks 12a, 12b are for example turned in the same direction, their seat 28 being oriented upwards and their spout 27 downwards, as illustrated in FIGS. 3 to 6. The first hook 12a is thus designed to steer over the upper edge 11, so that its seat 28 is in contact with said upper edge 11, so that its spout 27 prevents the first shading screen 5a from being separated from the first side wall 9a by entering contact with said upper edge 11, and that its base 29 prevents the first shading screen 5a to be brought closer to the latter by coming into contact with said upper edge 11. The attachment of the second hook 12b to the hook 17 is based on a principle similar to that of the hooking of the first hook 12a on the upper edge 11. When the first side wall 9a and the roof 10 are in the mounted position, the seat 28 is preferably blocked by the roof 10, which covers then the upper edge 11 of the first side wall 9a. Thus, the first hook 12a can not be disengaged from the upper edge 11, and is straddled on said upper edge 11, its spacing of said upper edge 11 being blocked by the presence of the roof 10 to plumb. The first hook 12a and its tab 24 are preferably arranged upwardly of the panel 15, and the second hook 12b preferably downwards of the panel 15, so that the first shading screen 5a is positioned opposite and in the alignment of the first side wall 9a, the hook 17 itself being arranged on the bottom of the latter. Preferably, the catch 17 comprises a notch 13 formed through the first side wall 9a and sufficiently wide for said second hook 12b to pass therethrough, said notch 13 comprising a flange 14 on which the second hook 12b can be hung. The notch 13 is preferably of rectangular shape, the flange 14 forming the lower side of said notch 13. The second hook 12b is thus designed to straddle the flange 14, so that its seat 28 is in contact with said flange 14 , of 813767 / FR so that its spout 27 prevents the first shading screen 5a from being separated from the first side wall 9a at the notch 13 by coming into contact with the rim 14, and that its base 29 prevents the first shading screen 5a to be brought closer to the latter by coming into contact with the rim 14.

Preferably, the fastening system 6 comprises a third hook 12c and a fourth hook 12d, being identical to the first and second hooks 12a, 12b, the four hooks 12a-12d being distributed on the first shading screen so as to form a rectangle or a square, each hook being located near a corner of the panel 15 (as illustrated in Figures 3 and 4). The attachment device 8 is then adapted to receive all of these hooks, the edge 11 allowing for example to hang two hooks, and the attachment device 8 then comprising two hooks 17 distributed in the length of the first wall 9a and allowing to hang the two remaining hooks. The two hooks at the top then hook in the manner of the first hook 12a on the upper edge 11, the two hooks at the bottom hook in the manner of the second hook 12b in the corresponding hooks 17 formed for example by slots formed through the thickness of the panel 15 advantageously forming the first shading screen 5a. It is of course possible to envisage additional hooks without departing from the scope of the invention.

Preferably, the outer casing 3 is attached to a frame 26 forming the skeleton of the cabinet, and having horizontal beams 30 and vertical props 31. The roof 10 is integral with the frame 26, for example by means of the props 31, while the side walls 9 are integral with the longitudinal members 30. Preferably, the outer casing 3 also comprises a base 32 of parallelepipedal shape forming the base of the cabinet 1. Preferably, the upper face of the base 32 forms the pre-base 33 (that is to say the floor) of the compartment 4. On the periphery of said bottom 33, the base 32 has slots 34 arranged parallel to the peripheral edge of said pre-base 33, and intended to cooperate with tabs 35 of the side walls 9 (as illustrated in FIGS. 2, 8 and 9), preferably arranged along the lower side 21 of said side walls 9. Thus, each side wall 9, when not attached to the frame 26, can be positioned to 813767 / FR rotation on the base 32 by cooperation tabs 35 with the slots 34. In this situation, each paro Lateral side 9 can thus pivot about its tabs 35 inserted into slots 34 when it is not attached to frame 26. Preferably, the first shading screen 5a substantially covers the entire surface of the first wall 9a, to generate a shadow projected on all of it. Preferably, the cabinet 1 comprises a second shading screen 5b, which is attached to a second side wall 9b of the outer shell 3 to form a second air gap 7b, the characteristics of the first shading screen 10 then applying mutatis mutandis to the second shading screen 5b and the second side wall 9b. Preferably, the first and second shading screens 5a, 5b are arranged on the first and second side walls 9a, 9b which are placed parallel in opposition to one another in order to form two side faces of the cabinet 1 said first and second sidewalls 9a, 9b then being separated by the bottom wall 9c, opposite the access opening 36 closed by the front door 25 (as illustrated in FIGS. 1 and 2). Without departing from the scope of the invention, it is possible to envisage placing other shading screens on the bottom wall 9c and on the roof 10. The invention relates, according to a second aspect, to a method of transformation. an outdoor cabinet 1 intended to contain electronic, electrical or telecommunication equipment, said cabinet 1 preferably being in accordance with the foregoing description, and comprising an outer casing 3 delimiting a compartment 4 intended to receive said equipment. The method according to the invention is a method in which at least a first shading screen 5a is reported on the outer envelope 3 to generate a shadow on the latter, thanks to a fastening system 6 designed to attach removable the first shading screen 5a to said outer casing 3 so that said first shading screen 5a is kept facing and away from the outer casing 3 to thereby interpose a first air gap 7a between the casing outside 3 and the first shading screen 5a. In accordance with the process according to the invention, and as stated above, said first airfoil 7a opens directly into the open air along the majority of at least its perimeter. Of course, all the elements of the description set out above in relation to the cabinet 1 apply mutatis mutandis to the method of transforming the cabinet 1 according to the invention. The cabinet 1 transformed according to the processing method according to the invention makes it possible to confer on the cabinet 1 a better insulation of the solar rays and a better cooling of the material which it contains. Thus, the transformation method makes it possible, for example, to transform (or to contribute to transforming) a cabinet 1 intended to contain passive (non-heating) components in a transformed cabinet 1 intended to contain active (heating) components, the addition of the first shading screen 5a to improve the cooling and thermal insulation of said cabinet 1 sufficiently to allow active components to be contained in the compartment 4 and to operate normally without being degraded by excess heat. Preferably, the outer casing 3 comprises an attachment device 8, to which the fastening system 6 is designed to hang, the outer casing 3 comprising a roof 10 and a first side wall 9 which are fixed to the one to another, the fastening system 6 being designed to hook to said upper edge 11, said method comprising the following steps: - the roof 10 and the first side wall 9a are detached from each other, the fastening system 6 is attached to the upper edge 11, said roof 10 and said first side wall 9a are attached to each other so that said roof 10 is fixed to the first side wall 9a in order to limit the displacement of the fastening system 6 relative to the upper edge 11 so that the stall of said fastening system 6 of said upper edge is made impossible. Preferably, the roof 10 is fixed and attached to the frame 26. Thus, the first side wall 9a of the frame 26 is detached in a first step, in order to rotate the frame 26 via the connection formed for example by the insertion of the tabs 35 in the slots 34 of the base 32. It is therefore possible to separate the upper edge 11 of the roof 10, the first side wall 9a then remaining pivotally connected to the base 32, so that the first side wall 9a remains positioned and does not need to be supported by the user (as illustrated in Figures 2, 8 and 9). The upper edge 11 away from the roof 10, it is no longer covered by the latter, so that it becomes possible to hang the first hook 12a on said upper edge 11. The first side wall 9a is then attached to the frame 26, so that the first hook 12a is locked, the roof 10 then covering the upper edge 11 again.

Of course, a similar sequence of operations is preferably performed to detach the first shading screen 5a from the first side wall 9a. Preferably, the detachment of the first side wall 9a of the frame 26 is effected by the interior of the compartment 4 (as illustrated in Figures 9 and 10). For example, screws connecting the longitudinal members 30 of the frame 26 to said first side wall 9a are accessible from inside the compartment. Thus, preferably, before performing the detachment step of the first side wall 9a to the longitudinal members 30, the front door 25 is unlocked in order to access the compartment 4, from which it is possible to detach the first side wall 9a. Of course, a similar sequence of operations is preferably carried out to reattach the first side wall 9a to the frame 26. Preferably, the fastening system 6 used in the context of the method according to the invention comprises a first hook 12a intended to cooperate with the upper edge 11 and a second hook 12b intended to cooperate with a catch 17 forming part of the attachment device 8, and arranged on the first side wall 9a, said method comprising the following steps: - hooks the first hook 12a at the upper edge 11, - the second hook 12b is hooked to the catch 17, 513767 / FR 300 76 19 18 Preferably, the steps during which the first hook 12a is attached to the upper edge 11 and hangs the second hook 12b hook 17 are made at the same time.
