Description

La présente invention concerne un chapeau de protection pour robinet de réservoir de fluide sous pression ainsi qu'un réservoir correspondant.The present invention relates to a protective cap for pressurized fluid reservoir valve and a corresponding reservoir.

L'invention concerne plus particulièrement un chapeau de protection pour robinet de réservoir de fluide sous pression comprenant deux demi-coquilles assemblées l'une à l'autre, les deux demi-coquilles définissant une base inférieure destinée à être montée au niveau d'un orifice d'un réservoir, les deux demi-coquilles étant assemblées selon un plan perpendiculaire à la base et définissant un volume intérieur de protection pour un robinet, les deux demi-coquilles étant assemblées par des systèmes d'axes de fixation coopérant avec des logements formées dans les demi-coquilles, au moins l'une des demi-coquilles comprenant une ouverture pour l'accès au volume intérieur de protection.The invention relates more particularly to a protective cap for a pressurized fluid tank valve comprising two half-shells assembled to each other, the two half-shells defining a lower base intended to be mounted at a orifice of a reservoir, the two half-shells being assembled in a plane perpendicular to the base and defining an internal protective volume for a faucet, the two half-shells being assembled by means of fixing axes cooperating with housing formed in the half-shells, at least one of the half-shells comprising an opening for access to the inner protective volume.

Un chapeau de protection de robinet de bouteille de fluide sous pression doit satisfaire à plusieurs contraintes techniques. Le chapeau de protection doit assurer une protection mécanique efficace du robinet tout présentant une masse réduite, une bonne ergonomie d'accès au robinet ainsi qu'une facilité de préhension et de manipulation.A pressurized fluid cylinder valve protection cap must meet several technical constraints. The protective cap must provide effective mechanical protection of the faucet while having reduced mass, good ergonomics of access to the faucet as well as ease of handling and handling.

Les documents EP939875A1 et WO 2007/125240 décrivent par exemple chacun un tel chapeau de protection. Cependant, ce type de chapeau offre un nombre limité de fonctionnalités. Par ailleurs, ce type de chapeau peut présenter des problèmes de sécurité si le chapeau devait être démonté par des utilisateurs indélicats. De plus, certains chocs peuvent endommager la tenue de ce chapeau en deux parties assemblées.The documents EP939875A1 and WO 2007/125240 describe for example each such a protective cap. However, this type of hat offers a limited number of features. Moreover, this type of hat may have security problems if the hat was to be disassembled by unscrupulous users.

Les figures 2 et 3 illustrent la structure d'un chapeau de protection pour robinet de réservoir de fluide sous pression obtenu par l'assemblage de deux demi-coquilles 1, 2 identiques ou sensiblement identiques. La figure 3 illustre la face interne d'une des demi-coquilles. Les deux demi-coquilles 1, 2 sont assemblées l'une à l'autre pour former le chapeau de protection en définissant une base 11 inférieure destinée à être montée au niveau d'un orifice d'un réservoir. Par exemple, comme visible à la figure 3, la partie inférieure de chaque demi-coquille comporte une demi-bague 24 taraudé. Les deux demi-bagues assemblées forment ainsi une bague taraudée destinée coopérer avec un col fileté d'un réservoir de fluide sous pression. Bien entendu, cette portion taraudée des demi-coquilles 1, 2 peut venir se fixer sur une pièce intermédiaire distincte des demi-coquilles 1, 2 et disposée entre le réservoir et le chapeau. De même, la fixation le la base 11 du chapeau sur le réservoir peut utiliser tout autre système d'attache d'un filetage/taraudage, par exemple un serrage, un emboîtement,...The Figures 2 and 3 illustrate the structure of a protective cap for pressurized fluid tank valve obtained by assembling two identical or substantially identical half-shells 1, 2. The figure 3 illustrates the inner face of one of the half-shells. The two half-shells 1, 2 are assembled together to form the protective cap by defining a lower base 11 to be mounted at an orifice of a reservoir. For example, as visible in the figure 3 , the lower part of each half-shell comprises a threaded half-ring 24. The two assembled half-rings thus form a threaded ring intended to cooperate with a threaded neck of a fluid reservoir under pressure. Of course, this threaded portion of the half-shells 1, 2 can be fixed on a separate intermediate piece of the half-shells 1, 2 and disposed between the reservoir and the cap. Likewise, fixing the base 11 of the cap on the tank can use any other system of attachment of a thread / tapping, for example a tightening, a nesting, ...

Les deux demi-coquilles 1, 2 sont assemblées selon un plan perpendiculaire à la base 11. C'est-à-dire que le plan de jonction des deux demi-coquilles 1, 2 est vertical lorsque le chapeau est monté sur une bouteille qui est debout verticalement.The two half-shells 1, 2 are assembled in a plane perpendicular to the base 11. That is to say that the junction plane of the two half-shells 1, 2 is vertical when the cap is mounted on a bottle which is standing upright.

Comme représenté, les deux demi-coquilles 1, 2 peuvent être assemblées au moins dans leur partie inférieure et centrale via des systèmes classiques à axes 4 et/ou vis et/ou goujons ou tout autre élément approprié. Par exemple, et comme visible à la figure 3, chaque demi-coquille comprend une pluralité de logements 14 conjugués prévus pour le passages d'axes de fixation dont les extrémités sont reliées respectivement aux deux demi-coquilles 1, 2. Bien entendu, les deux demi-coquilles 1, 2 peuvent être fixées l'une à l'autre via d'autres organes appropriés.As shown, the two half-shells 1, 2 can be assembled at least in their lower and central part via conventional systems with axes 4 and / or screws and / or studs or any other appropriate element. For example, and as visible at the figure 3 each half-shell comprises a plurality of conjugate housings 14 provided for the passage of fastening axes whose ends are respectively connected to the two half-shells 1, 2. Of course, the two half-shells 1, 2 can be fixed to one another via other appropriate bodies.

Classiquement, au moins l'une des demi-coquilles 1, 2 comprend une forme adaptée telle qu'une découpe ou discontinuité ou variation de contour formant, en position assemblée des deux-demi-coquilles, une ou des ouvertures 3, 13 prévues pour l'accès au volume intérieur de protection. Bien entendu, au moins une demi-coquille 1, 2 peut comporter une ou plusieurs ouvertures.Classically, at least one of the half-shells 1, 2 comprises a suitable shape such as a cut or discontinuity or contour variation forming, in the assembled position of the two half-shells, one or more openings 3, 13 provided for access to the interior protective volume. Of course, at least one half-shell 1, 2 may comprise one or more openings.

Par exemple, les deux demi-coquilles 1, 2 assemblées forment une ouverture supérieure dans la partie supérieure du chapeau et une ouverture 3 latérale adjacente dans la partie latérale du chapeau. Les ouvertures supérieure et latérale 3 sont séparées par une armature 7 longitudinale en forme de montant parallèle au plan de la base 11 du chapeau. Cette armature 7 est formée par la jonction locale des demi-coquilles 1, 2 et constitue de préférence une poignée de préhension supérieure du chapeau.For example, the two assembled half-shells 1, 2 form an upper opening in the upper part of the cap and an adjacent lateral opening 3 in the lateral part of the cap. The upper and lateral openings 3 are separated by a longitudinal rod-shaped reinforcement 7 parallel to the plane of the base 11 of the cap. This reinforcement 7 is formed by the local junction of the half-shells 1, 2 and is preferably an upper gripping handle of the cap.

Selon une particularité particulièrement avantageuse, le chapeau comprend, de préférence au niveau d'une de ses extrémités supérieures, une pièce 5 de renfort et de verrouillage supplémentaire des deux demi-coquilles 1, 2 assemblées. La pièce 5 de renfort et de verrouillage comprend deux extrémités accrochées respectivement sur les deux demi-coquilles 1, 2 pour assurer un renfort supplémentaire de l'assemblage des deux-demi-coquilles 1, 2.According to a particularly advantageous feature, the cap comprises, preferably at one of its upper ends, an additional reinforcing and locking part 5 of the two half-shells 1, 2 assembled. The reinforcement and locking part 5 comprises two ends hooked respectively on the two half-shells 1, 2 to provide additional reinforcement of the assembly of the two half-shells 1, 2.

Comme représenté aux figures 1 à 6, la pièce 5 de renfort et de verrouillage vient de préférence se fixer au niveau de l'armature 7 formée par la jonction locale des demi-coquilles 1, 2 et constituant une poignée de préhension supérieure.As represented in Figures 1 to 6 , the reinforcing and locking part 5 is preferably fixed at the level of the armature 7 formed by the local junction of the half-shells 1, 2 and constituting an upper gripping handle.

La pièce 5 de renfort et de verrouillage a par exemple la forme générale d'une poutre courbée en U qui est fixée sur une portion 7 courbe de forme conjuguée formée par les demi-coquilles 1, 2. Chaque extrémité de la pièce 5 de renfort et de verrouillage est accrochée sur une demi-coquille 1, 2 par exemple via au moins un et de préférence deux crochets 15 (cf. figures 6 et 7). Chaque crochet 15 solidaire de la pièce 5 de renfort et de verrouillage coopère en encliquetage avec un logement 6 conjugué respectif situé sur la demi-coquille 1, 2 concernée (cf. figures 2, 8 et 9).The reinforcing and locking part 5 has for example the general shape of a U-shaped curved beam which is fixed on a conjugate shaped curve portion 7 formed by the half-shells 1, 2. Each end of the reinforcing piece 5 and lock is hung on a half-shell 1, 2 for example via at least one and preferably two hooks 15 (cf. Figures 6 and 7 ). Each hook 15 integral with the reinforcing and locking part 5 cooperates in snap engagement with a respective conjugate housing 6 located on the half-shell 1, 2 concerned (cf. figures 2 , 8 and 9 ).

La pièce 5 de renfort et de verrouillage permet de diffuser les efforts (chocs, déformations) de façon relativement uniforme entre les deux demi-coquilles 1, 2. Ceci permet de limiter les efforts néfastes au niveau des axes de solidarisation des deux demi-coquilles 1, 2.The reinforcing and locking part 5 makes it possible to diffuse the forces (shocks, deformations) relatively uniformly between the two half-shells 1, 2. This makes it possible to limit the harmful forces at the level of the fastening axes of the two half-shells. 1, 2.

De préférence la pièce 5 de renfort et de verrouillage est fixée sur les demi-coquilles 1, 2 de façon non démontable, c'est-à-dire que le démontage de la pièce 5 de renfort et de verrouillage par rapport aux demi-coquilles 1, 2 n'est pas possible sans détériorer la pièce 5 de renfort et de verrouillage et/ou une demi-coquille. La pièce 5 de renfort et de verrouillage assure ainsi une fonction de scellement des deux demi-coquille 1, 2.Preferably the reinforcing and locking part 5 is fixed on the half-shells 1, 2 non-releasably, that is to say that the disassembly of the reinforcing and locking part 5 with respect to the half-shells 1, 2 is not possible without damaging the part 5 of reinforcement and locking and / or a half-shell. The reinforcing and locking part 5 thus provides a sealing function for the two half-shells 1, 2.

Les crochets 15 de la pièce 5 de renfort et de verrouillage sont de préférence encliquetés de façon non accessible au démontage pour assurer une inviolabilité de l'intégrité du chapeau.The hooks 15 of the reinforcing and locking part 5 are preferably snapped not accessible to disassembly to ensure inviolability of the integrity of the cap.

Comme visible aux figures 4, 6 et 7, à chaque extrémité de la pièce 5 de renfort et de verrouillage le ou les crochets 15 peuvent être situés à l'extrémité d'un rail solidaire de la pièce 5 de renfort et de verrouillage. Lors du montage de la pièce 5 de renfort et de verrouillage, les deux rails 25 peuvent être admis à coulisser dans rainures 35 longitudinales complémentaires respectives formées sur les demi-coquilles 1, 2.As visible to Figures 4, 6 and 7 , at each end of the reinforcing and locking part 5 or the hooks 15 may be located at the end of a rail secured to the reinforcing and locking part 5. During the mounting of the reinforcement and locking part 5, the two rails 25 can be slid into respective complementary longitudinal grooves 35 formed on the half-shells 1, 2.

Comme visible aux figures 6, 7 et 8, une partie, par exemple centrale, de la pièce 5 de renfort et de verrouillage peut comprendre un ou plusieurs pion 7 qui viennent se placer dans des logements complémentaires respectifs formés dans les demi-coquilles 1, 2. De préférence, les pions 7 sont situés sur une nervure flexible de la pièce 5 de renfort et de verrouillage.As visible to Figures 6, 7 and 8 a part, for example central, of the reinforcing and locking part 5 may comprise one or more pins 7 which are placed in respective complementary housings formed in the half-shells 1, 2. Preferably, the pins 7 are located on a flexible rib of the reinforcing and locking part 5.

Les pions 7 ont par exemple la forme de dômes. Après verrouillage de la pièce 5 de renfort et de verrouillage sur les demi-coquilles 1, 2, les dômes positionnés en opposition sur des nervures flexibles permettent l'absorption des jeux de montage entre les demi-coquilles 1, 2 et la pièce 5 de renfort et de verrouillage.The counters 7 have for example the shape of domes. After locking the reinforcing and locking part 5 on the half-shells 1, 2, the opposing dia-mers on flexible ribs allow the absorption of the mounting clearances between the half-shells 1, 2 and the piece 5 of reinforcement and locking.

De préférence, la pièce 5 de renfort et de verrouillage a, en section transversale, une forme non plane et enveloppante qui vient envelopper l'armature 7 formée par les demi-coquilles 1, 2. Par exemple, comme visible aux figures 2, 6 et 7, la pièce 5 de renfort et de verrouillage a une section transversale de forme générale en U dont la concavité vient accueillir en son sein l'armature 7 (cf. notamment la section coupée illustrée à la figure 7).Preferably, the reinforcing and locking part 5 has, in cross section, a non-planar and enveloping shape which comes to envelop the armature 7 formed by the half-shells 1, 2. For example, as visible at figures 2 , 6 and 7 , the part 5 of reinforcement and locking has a cross section of shape U-shaped, the concavity of which encloses the frame 7 (see in particular the cut section illustrated at figure 7 ).

Cette configuration permet d'améliorer encore plus le verrouillage des deux demi-coquilles, le renforcement mécanique du chapeau et la diffusion des efforts dans le chapeau en cas de choc. En particulier, cette structure permet d'éviter de concentrer des efforts au niveau des axes de fixation du chapeau lorsque le chapeau est soumis à des chocs violents.This configuration makes it possible to further improve the locking of the two half-shells, the mechanical reinforcement of the cap and the diffusion of the forces in the cap in the event of impact. In particular, this structure makes it possible to avoid concentrating efforts at the fastening axes of the cap when the cap is subjected to violent shocks.

Avantageusement, la matière constituant ou recouvrant la pièce 5 de renfort et de verrouillage formant la poignée supérieure est photo-luminescente. Ceci permet un repérage plus du robinet abrité dans le chapeau, par exemple en cas de situation enfumée, polluée... De plus, une fenêtre de visualisation d'informations relatives à la bouteille peut être prévue au travers de la poignée.Advantageously, the material constituting or covering the reinforcing and locking part 5 forming the upper handle is photo-luminescent. This allows more identification of the faucet housed in the cap, for example in case of smoky, polluted ... In addition, an information display window relating to the bottle can be provided through the handle.

Cette pièce 5 de renfort et de verrouillage peut également être prévue dans une couleur déterminée d'un chapeau à l'autre, pour identifier par exemple la nature du gaz contenu dans bouteille munie de ce chapeau.This reinforcement and locking piece 5 can also be provided in a specific color from one hat to the other, to identify, for example, the nature of the gas contained in the bottle provided with this cap.

Comme visible aux figures 3 et 4, au moins une partie de la bordure 9 des demi-coquilles 1, 2 peut comporter une nervure ou une pliure de renforcement vers l'intérieur du chapeau. Cette configuration permet de rigidifier et de diffuser les efforts en cas de choc et/ou de déformation sur l'ensemble.As visible to figures 3 and 4 at least a portion of the edge 9 of the half-shells 1, 2 may comprise a rib or a reinforcing fold towards the inside of the cap. This configuration makes it possible to stiffen and diffuse the forces in the event of impact and / or deformation on the assembly.

Chaque demi-coquille 1, 2 peut comporter des parois internes 19, 39 définissant une enceinte de protection interne supplémentaire (cf. 3 ou 14). Cette enceinte 9, 39 comprend par exemple des plans inclinés pour guider et évacuer du liquide vers l'extérieur du volume intérieur du chapeau. Ces parois forment par exemple un carénage intérieur de chapeau possédant des plans inclinés sur deux niveaux pour permettre et favoriser l'évacuation de liquide.Each half-shell 1, 2 may comprise internal walls 19, 39 defining an additional internal protective enclosure (see 3 or 14). This enclosure 9, 39 comprises, for example, inclined planes for guiding and discharging liquid towards the outside of the interior volume of the cap. These walls form for example an inner cap fairing having inclined planes on two levels to allow and promote the evacuation of liquid.

De préférence, chaque demi-coquille 1, 2 comprend, sur sa surface intérieure tournée vers le volume intérieur de protection, au moins une nervure 8 de renforcement. Par exemple, chaque demi-coquille 1, 2 comprend plusieurs (par exemple trois) nervures 8 qui s'étendant dans la direction inférieure-supérieure (de la base vers la partie supérieure. L'extrémité supérieure de ces nervures 8 est raccordée de préférence à une extrémité de l'armature 7 constituant la poignée de préhension supérieure.Preferably, each half-shell 1, 2 comprises, on its inner surface facing the inner protective volume, at least one reinforcing rib 8. For example, each half-shell 1, 2 comprises several (for example three) ribs 8 which extend in the lower-upper direction (from the base to the upper part, the upper end of these ribs 8 is connected preferably at one end of the frame 7 constituting the upper grip.

Ces nervures 8, de préférence concentriques à l'ouverture latérale située sous la poignée 7, 5 supérieure permettent également d'absorber et de diffuser les chocs et/ou déformations sur l'ensemble de la structure de protection.These ribs 8, preferably concentric with the lateral opening located under the upper handle 7, 5 also make it possible to absorb and diffuse shocks and / or deformations on the whole of the protective structure.

Comme visible à la figure 1, l'extrémité inférieure de chaque enveloppe peut comporter une portions s'étendant vers le bas latéralement en forme de jupe courbe (ou ajourée) pour former une poignée 100 inférieure latérale de préhension. Ces deux poignées 100 inférieures latérales permettent de soulever verticalement une bouteille munie d'un tel chapeau avec deux mains, comme illustré à la figure 17.As visible at figure 1 , the lower end of each envelope may comprise a downwardly extending portions laterally in the form of a curved skirt (or openwork) to form a lower lateral gripping handle 100. These two lower lateral handles 100 make it possible to vertically raise a bottle provided with such a cap with two hands, as shown in FIG. figure 17 .

Comme illustré aux figures 1 et 2 notamment, les deux demi-coquilles 1, 2 peuvent comporter des portions s'étendant vers le bas et l'arrière (en direction opposée à celle de la poignée 5, 7 supérieure). Ces portions de matière des deux demi-coquilles 1, 2 sont de préférence convexes vers l'extérieur du chapeau pour former une poignée inférieure arrière. Cette poignée 10 inférieure arrière permet de porter la bouteille de façon inclinée avec une seule main comme représenté à la figure 14. La poignée supérieur 7, 5 permet quant à elle de soulever la bouteille verticalement avec une main (cf. figure 16).As illustrated in Figures 1 and 2 in particular, the two half-shells 1, 2 may comprise portions extending downwardly and rearwardly (in the opposite direction to that of the upper handle 5, 7). These portions of material of the two half-shells 1, 2 are preferably convex towards the outside of the cap to form a rear lower handle. This bottom bottom handle 10 allows the bottle to be tilted with one hand as shown in FIG. figure 14 . The upper handle 7, 5 makes it possible to lift the bottle vertically with one hand (cf. figure 16 ).

Comme représenté à la figure 14, et tout comme les poignées 100 inférieures latérales, cette poignée 10 inférieure arrière peut en variante être réalisée sous la forme d'une ouverture permettant le passage de doigts.As represented in figure 14 , and like the lower side handles 100, this rear lower handle may alternatively be in the form of an opening for the passage of fingers.

Ainsi, et indépendamment des caractéristiques de pièce de renfort et de verrouillage et indépendamment des caractéristiques de crochet, le chapeau peut comporter, en plus de la poignée 5, 7 supérieure, une, deux ou trois poignées inférieurs qui peuvent être latérales 100 et/ou arrière 10. Ceci confère une grande ergonomie pour le portage de la bouteille (par le dessus, par le dessous ou par le côté).Thus, and independently of the reinforcing and locking member characteristics and independently of the hook characteristics, the cap may comprise, in addition to the upper handle 5, 7, one, two or three lower handles which may be lateral 100 and / or 10. This gives great ergonomics for the port of the bottle (from above, from below or from the side).

La ou les poignées peuvent comporter une surface anti-glissement. Par exemple, cette surface d'accroche anti-glissement vient coopérer avec la première phalange des doigts de l'utilisateur. La forme concave ou l'ouverture de chaque poignée est dimensionnée pour accueillir par exemple quatre doigts de la main d'un utilisateur.The handle or handles may have an anti-slip surface. For example, this anti-slip grip surface cooperates with the first phalanx of the fingers of the user. The concave shape or the opening of each handle is sized to accommodate for example four fingers of the hand of a user.

De préférence, au moins l'une des poignées forme une butée empêchant la rotation d'une bouteille cylindrique couchée munie d'un tel chapeau. C'est à dire que l'une au moins des poignées 10 forme une surface d'appui stable faisant saillie relativement au diamètre de la bouteille munie du chapeau.Preferably, at least one of the handles forms a stop preventing rotation of a cylindrical bottle coated with such a cap. That is, at least one of the handles 10 forms a stable bearing surface protruding from the diameter of the bottle provided with the cap.

Les figures 10 et 11 illustrent un chapeau pourvu d'un crochet 12 d'attache ou de suspension du chapeau. Le crochet 12 permet notamment d'accrocher une bouteille par son chapeau à un barreau d'un lit.The Figures 10 and 11 illustrate a hat provided with a hook 12 attachment or suspension of the hat. The hook 12 allows in particular to hang a bottle by his hat to a bar of a bed.

Le crochet 12 est monté coulissant dans le chapeau entre une position déployée et une position rétractée relativement au volume du chapeau. De préférence, l'axe de coulissement du crochet 12 est incliné en direction de la partie supérieure du chapeau d'un angle compris entre 20 et 80 degrés et de préférence entre 30 et 60 degrés par rapport au plan de la base 11 inférieure du chapeau.The hook 12 is slidably mounted in the cap between an extended position and a retracted position relative to the volume of the cap. Preferably, the axis of sliding of the hook 12 is inclined towards the upper part of the cap by an angle of between 20 and 80 degrees and preferably between 30 and 60 degrees with respect to the plane of the lower base 11 of the cap. .

Le crochet 2 a par exemple une structure filaire à deux branches latérales dont les deux extrémités forment des tiges rectilignes qui sont coulissantes dans respectivement les demi-coquilles 1, 2. Un organe de verrouillage du crochet 12 dans au moins l'une de ces positions extrême peut être prévu.The hook 2 has for example a wire structure with two lateral branches, the two ends of which form straight rods which slide in respectively the half-shells 1, 2. A locking member of the hook 12 in at least one of these positions extreme can be expected.

Dans la forme de réalisation des figures 4, 5, 12 et 13, le crochet 12 est articulé sur le chapeau entre une position relevée et une position rabattue. Par exemple, le crochet 2 comporte une structure filaire dont les deux extrémités sont montée articulées respectivement sur les deux demi-coquilles 1, 2.In the embodiment of the Figures 4, 5 , 12 and 13 , the hook 12 is articulated on the cap between a raised position and a folded position. For example, the hook 2 comprises a wire structure whose two ends are hinged respectively on the two half-shells 1, 2.

Comme visible aux figures 12 et 13, chaque demi-coquille 1, 2 peut comporter une butée 13 de blocage permettant de bloquer sélectivement une extrémité du crochet 12 d'attache en position relevée ou en position rabattue. Chaque butée 13 peut comprendre deux plans inclinés formant des surfaces d'appui et de maintien du crochet 12 d'attache respectivement en position relevée ou en position rabattue. Par exemple, le passage d'une position stable à l'autre est obtenu par déplacement et/ou déformation élastique relative du crochet 12 par rapport à la butée 13.As visible to Figures 12 and 13 each half-shell 1, 2 may comprise a locking abutment 13 for selectively blocking an end of the hook 12 attachment in the raised position or in the folded position. Each abutment 13 may comprise two inclined planes forming bearing and holding surfaces of the attachment hook 12 respectively in the raised position or in the folded position. For example, the passage from one stable position to the other is obtained by displacement and / or relative elastic deformation of the hook 12 with respect to the abutment 13.

Les demi-coquilles 1, 2 peuvent être constitué de l'un au moins des matériaux parmi : du métal, un alliage métallique, un plastique tel qu'un polymère.The half-shells 1, 2 may consist of at least one of: metal, a metal alloy, a plastic such as a polymer.

La pièce 5 de renfort et de verrouillage peut être constituée de l'un au moins des matériaux parmi : du métal, un alliage métallique, un plastique tel qu'un polymère.The reinforcing and locking part 5 may consist of at least one of: metal, a metal alloy, a plastic such as a polymer.

On comprend donc que, tout en étant de structure simple et peu coûteuse, le chapeau selon l'invention présente une grande résistance aux chocs et aux démontages sauvages.It is therefore understood that, while being simple and inexpensive structure, the hat according to the invention has a high resistance to shock and disassembly wild.
