Lorsqu'un chapeau de protection est installé ou démonté d'une bouteille, ces tâches peuvent nécessiter un certain nombre d'opérations et/ou d'outils.When a protective cap is installed or removed from a cylinder, these tasks may require a number of operations and / or tools.

En particulier, lorsque les chapeaux sont assemblés par vissage ou analogue sur une extrémité (col) de la bouteille, le système d'accrochage sur la bouteille (le filetage dans le cas d'un système vissé) peut être abîmé. Il est donc nécessaire de prévoir sur le chapeau un système déformable facilitant le montage ou le démontage du chapeau.In particular, when the caps are assembled by screwing or the like on one end (neck) of the bottle, the hooking system on the bottle (the thread in the case of a screwed system) can be damaged. It is therefore necessary to provide on the bonnet a deformable system facilitating the assembly or disassembly of the bonnet.

Les solutions connues consistent à prévoir un chapeau dont la structure comporte plusieurs parties (par exemple deux-demi-coques) et éventuellement une bague intermédiaire fendue, un outil écarteur...The known solutions consist in providing a cap whose structure comprises several parts (for example two-half-shells) and possibly a split intermediate ring, a spacer tool, etc.

Un chapeau 1 de protection de robinet 7 de bouteille 6 de fluide sous pression comprend classiquement une structure 2 rigide délimitant un volume de protection pour un robinet 7 (cf. figure 1).A protective cap 1 for a valve 7 of a pressurized fluid bottle 6 conventionally comprises a rigid structure 2 delimiting a protective volume for a valve 7 (cf. figure 1 ).

Cette structure 2 rigide, exemple en forme de cage, d'arceau ou de tube, comporte une extrémité inférieure destinée à être fixée sur l'extrémité supérieure d'une bouteille de fluide sous pression.This rigid structure 2, for example in the form of a cage, hoop or tube, has a lower end intended to be fixed to the upper end of a pressurized fluid bottle.

Cette extrémité inférieure peut comprendre en particulier un collier 4 de montage prévu pour être fixé sur le col (par exemple cylindrique) de l'extrémité supérieure d'une bouteille 6. Ce collier 4 peut être fixé directement sur la bouteille 6 ou sur une pièce intermédiaire disposée entre le chapeau 1 et la bouteille 6.This lower end can comprise in particular a mounting collar 4 intended to be fixed on the neck (for example cylindrical) of the upper end of a bottle 6. This collar 4 can be fixed directly on the bottle 6 or on a part. intermediate placed between the cap 1 and the bottle 6.

Classiquement, au moins une partie de la surface interne du collier 4 est munie d'empreintes 40 d'accrochage destiné à coopérer en accrochage avec un système 49 d'empreintes conjuguées situées sur l'extrémité supérieure de la bouteille 6.Conventionally, at least part of the internal surface of the collar 4 is provided with hooking impressions 40 intended to cooperate in coupling with a system 49 of conjugate impressions located on the upper end of the bottle 6.

Le système d'empreinte peut comporter des nervures et creux pour bloquer le chapeau 1 en translation verticale sur la bouteille 6 et de préférence le bloquer également en rotation autour de l'axe longitudinal de la bouteille 6.The impression system may include ribs and hollows to block the cap 1 in vertical translation on the bottle 6 and preferably also to block it in rotation around the longitudinal axis of the bottle 6.

Un système d'accrochage classique est le vissage. C'est-à-dire que collier 4 du chapeau 1 est taraudé et vient se visser sur un filetage sur la bouteille 6.A classic hanging system is screwing. That is, collar 4 of cap 1 is threaded and is screwed onto a thread on bottle 6.

Dans l'exemple non limitatif des figures, le collier 4 est composé de deux portions 41, 42 susceptibles d'être déplacées l'une relativement à l'autre, par exemple par déformation élastique, pour augmenter ou réduire le diamètre dudit collier 4 en vue de faciliter son démontage et/ou son montage.In the non-limiting example of the figures, the collar 4 is composed of two portions 41, 42 capable of being moved relative to one another, by for example by elastic deformation, to increase or reduce the diameter of said collar 4 in order to facilitate its removal and / or its assembly.

Le chapeau 1 comprend un dispositif de serrage ou de desserrage du collier 4 ou de desserrage pour réduire ou augmenter son diamètre.The cap 1 comprises a device for tightening or loosening the collar 4 or for loosening it to reduce or increase its diameter.

Ce dispositif comprend un système de type à vis 47 et écrou 48.This device comprises a screw 47 and nut 48 type system.

Comme visible à la figure 4, les deux portions 41, 42 du collier 4 comprennent chacune un logement 44, 45 respectif situé de façon adjacente à l'interstice (c'est-à-dire de façon adjacente à la découpe du collier 4).As visible at the figure 4 , the two portions 41, 42 of the collar 4 each comprise a respective housing 44, 45 located adjacent to the gap (that is to say adjacent to the cutout of the collar 4).

Un premier logement 44 est prévu pour accueillir: une première extrémité d'une tête 46 de la vis 47. Le second logement 45 est prévu pour accueillir l'écrou 48 et l'extrémité de la vis sur laquelle il est monté.A first housing 44 is provided to receive: a first end of a head 46 of the screw 47. The second housing 45 is provided to accommodate the nut 48 and the end of the screw on which it is mounted.

Le dispositif à vis 47 et écrou 48 forme un système de réglage du diamètre ou de la forme du collier 4 via le contrôle de l'écartement de l'interstice 43.The screw 47 and nut 48 device forms a system for adjusting the diameter or the shape of the collar 4 via the control of the spacing of the gap 43.

Chaque logement 44, 45 comprend des parois 144, 244, 145, 245 respectives formant un système de butées pour respectivement la tête 46 de vis et l'écrou 48. Ainsi, pour faciliter le montage du chapeau 1 sur la bouteille 6, le système vis-écrou est desserré jusqu'à l'appui de l'écrou 48 et de la tête de vis sur les parois correspondantes des logements. Un couple supplémentaire est appliqué pour écarter les deux faces permettant l'agrandissement du diamètre du filetage.Each housing 44, 45 comprises respective walls 144, 244, 145, 245 forming a system of stops for respectively the head 46 of the screw and the nut 48. Thus, to facilitate the mounting of the cap 1 on the bottle 6, the system screw-nut is loosened until the nut 48 and the screw head rest on the corresponding walls of the housings. An additional torque is applied to separate the two faces allowing the enlargement of the diameter of the thread.

C'est-à-dire que, lors de l'écartement relatif de l'écrou 48 et de la tête 46 de vis, des faces d'extrémités de ces derniers génèrent un effort sur des parois 144,145 d'extrémité des logements 44, 45. Ceci permet d'écarter les deux portions 41, 42 du collier 4 (cf. figure 5 où le dévissage qui provoque l'écartement est symbolisé par deux flèches divergentes).That is to say that, during the relative separation of the nut 48 and the screw head 46, the end faces of the latter generate a force on the end walls 144,145 of the housings 44, 45. This makes it possible to separate the two portions 41, 42 of the collar 4 (cf. figure 5 where the unscrewing which causes the separation is symbolized by two divergent arrows).

Le chapeau 1 peut ensuite être vissé plus facilement sur la bouteille 6 par vissage via le système de filetage/taraudage (ou un autre système équivalent). Dès que la position de l'assemblage du chapeau 1 sur la bouteille est satisfaisante, le chapeau 1 peut être maintenu dans sa position par le serrage de l'ensemble vis/écrou.The cap 1 can then be screwed more easily onto the bottle 6 by screwing via the threading / tapping system (or another equivalent system). As soon as the position of the cap assembly 1 on the bottle is satisfactory, the cap 1 can be maintained in its position by tightening the screw / nut assembly.

Lors du rapprochement relatif de l'écrou 48 et de la tête 46 de vis, des faces intérieures (c'est-à-dire les faces adjacentes à l'interstice 43) de ces derniers génèrent un effort sur des parois 244, 245 interne des logements 44, 45. Ceci permet de rapprocher les deux portions 41, 42 du collier 4 et le cas échant refermer l'interstice 43 (cf. figure 6 où le vissage qui provoque le rapprochement est symbolisé par deux flèches convergentes).During the relative approximation of the nut 48 and the screw head 46, the internal faces (that is to say the faces adjacent to the interstice 43) of the latter generate a force on the internal walls 244, 245. of housing 44, 45. This makes it possible to bring the two portions 41, 42 of the collar 4 together and, if necessary, to close the gap 43 (cf. figure 6 where the screwing which causes the approximation is symbolized by two converging arrows).

Pour bloquer la position du chapeau 1, la vis 47 peut être serrée jusqu'à l'appui de la tête 46 de vis sur la paroi 244 interne du logement 44. Un couple de serrage supplémentaire peut être appliqué pour rapprocher les deux parties 41, 42 permettant le blocage en rotation des filets du chapeau 1 sur les filets de la bouteille 6.To lock the position of the cap 1, the screw 47 can be tightened until the screw head 46 rests on the internal wall 244 of the housing 44. An additional tightening torque can be applied to bring the two parts 41 together, 42 allowing the rotation of the threads of the cap 1 on the threads of the bottle 6.

Le démontage peut être réalisé selon le processus inverse. Le dispositif vis/écrou peut être desserré jusqu'à l'appui sur les parois 144, 145 d'extrémité des logements 44, 45 (c'est-à-dire sur les parois 144, 145 des logements opposées aux parois internes 244, 245). Puis un couple supplémentaire peut être est appliqué pour écarter les deux faces permettant l'agrandissement du diamètre de filetage Le chapeau 1 peut alors être dévissé plus facilement de la bouteille 6.Disassembly can be done in reverse. The screw / nut device can be loosened until it rests on the end walls 144, 145 of the housings 44, 45 (that is to say on the walls 144, 145 of the housings opposite the internal walls 244, 245). Then an additional torque can be applied to separate the two faces allowing the enlargement of the thread diameter.The cap 1 can then be unscrewed more easily from the bottle 6.

Ainsi, le même système à vis 47 et écrou 48 peut être utilisé à la fois dans les phases de montage et démontage du chapeau 1 par rapport à la bouteille 6 (pour écarter ou serrer le collier 4 du chapeau 1).Thus, the same screw system 47 and nut 48 can be used both in the phases of assembly and disassembly of the cap 1 with respect to the bottle 6 (to separate or tighten the collar 4 of the cap 1).

De préférence des parois distinctes forment des butées pour respectivement, le serrage et le déserrage. Le desserrage permet d'agrandir le cas échant l'interstice 43 au delà de sa taille « normale) (la taille normale fait référence à la taille de l'interstice 43 lorsque le collier est au repos, c'est-à-dire non sujet à un effort de serrage ou de desserrage).Preferably, separate walls form stops for tightening and loosening, respectively. Loosening allows the gap 43 to be enlarged beyond its “normal” size (the normal size refers to the size of the gap 43 when the collar is at rest, that is to say no subject to a tightening or loosening force).

Par exemple, la ou les parois 144 d'extrémité, et notamment la paroi d'extrémité coopérant avec la tête 46 de la vis forme une butée permettant au système vis/écrou d'écarter les deux portions.For example, the end wall or walls 144, and in particular the end wall cooperating with the head 46 of the screw, forms a stop allowing the screw / nut system to separate the two portions.

L'écrou 48 et la tête 46 de la vis comportent par exemple des faces perpendiculaires à l'axe longitudinal de la vis 47. Les parois 144, 244, 145, 245 des logements 44, 45 forment un système de butées pour respectivement la tête 46 de vis et l'écrou 48 qui sont également perpendiculaires à l'axe longitudinal de la vis 47.The nut 48 and the head 46 of the screw comprise, for example, faces perpendicular to the longitudinal axis of the screw 47. The walls 144, 244, 145, 245 of the housings 44, 45 form a system of stops for the head respectively. 46 screw and nut 48 which are also perpendicular to the longitudinal axis of screw 47.

De préférence l'écrou 48 est bloqué en rotation dans son logement 45 autour de l'axe longitudinal de la vis 47 (par exemple l'écrou 48 est carré est reçu dans un logement complémentaire qui le bloque en rotation autour de l'axe longitudinal de la vis 47). Selon une alternative possible l'écrou peut tourner dans son logement et dans ce cas, son blocage en rotation est assuré par un outil (clé tournevis) manipulé par un opérateur.Preferably the nut 48 is locked in rotation in its housing 45 around the longitudinal axis of the screw 47 (for example the nut 48 is square and is received in a complementary housing which blocks it in rotation around the axis length of the screw 47). According to one possible alternative, the nut can rotate in its housing and in this case, its locking in rotation is ensured by a tool (screwdriver wrench) handled by an operator.

La tête 46 de la vis 47 est libre en rotation dans son logement 44 autour de l'axe longitudinal de la vis 47. Le chapeau 1 comporte un orifice 50 ou passage d'accès au volume interne de logement 44 qui abrite la tête 46 vis pour permettre le passage d'un outil (une vis ou clé ou autre) et permettre la rotation de la tête 46 de la vis 47.The head 46 of the screw 47 is free to rotate in its housing 44 around the longitudinal axis of the screw 47. The cap 1 has an orifice 50 or passage for access to the internal volume of the housing 44 which houses the head 46 of the screw. to allow the passage of a tool (a screw or wrench or other) and allow the rotation of the head 46 of the screw 47.

Sans que ceci ne soit limitatif, la vis 47 d'assemblage peut être par exemple du type à six pans creux.Without this being limiting, the assembly screw 47 may for example be of the type with hexagon socket.

L'écrou peut avoir une forme hexagonale, triangulaire ou toute autre forme appropriée.The nut can have a hexagonal, triangular or any other suitable shape.

La tête 46 de la vis 47 possède de préférence un jeu dans son logement 44, 45 selon une direction parallèle à l'axe longitudinale de la vis 47.The head 46 of the screw 47 preferably has play in its housing 44, 45 in a direction parallel to the longitudinal axis of the screw 47.

L'écrou 48 et/ou la vis 47 et notamment la tête 46 de la vis sont de préférence logés de façon stable dans leur logement 44, 45, notamment par emmanchement. C'est-à-dire que le système de serrage/desserrage est solidaire du collier 4 ou chapeau 1. L'opérateur n'a pas à manipuler des pièces distinctes et risque moins de les perdre. Par exemple, le chapeau 1 possède une empreinte spécifique comportant ou plusieurs zones permettant l'insertion et le maintien de la vis 47 et de l'écrou 48. D'autres solutions que la mise en place en force peuvent être prévues (collage, soudure,...).The nut 48 and / or the screw 47 and in particular the head 46 of the screw are preferably housed in a stable manner in their housing 44, 45, in particular by fitting. That is to say that the clamping / loosening system is integral with the collar 4 or cap 1. The operator does not have to handle separate parts and is less likely to lose them. For example, the cap 1 has a specific cavity comprising or more zones allowing the insertion and the maintenance of the screw 47 and of the nut 48. Other solutions than the installation by force can be envisaged (gluing, welding. , ...).

Comme représenté à la figure 7, l'écrou 48 distinct du chapeau peut être remplacé par un taraudage formé dans une portion du chapeau formant un logement 45 taraudé destiné à accueillir l'extrémité de la vis 47. C'est-à-dire que la vis 47 est vissée directement dans une portion taraudée du chapeau ou d'une pièce solidaire du chapeau. L'effort de serrage/déserrage est transmis dans ce cas directement au chapeau (collier 4) via les filets du taraudage. C'est-à-dire que la portion taraudée forme un écrou qui coopère avec la vis 47.As shown in the figure 7 , the nut 48 separate from the cap can be replaced by an internal thread formed in a portion of the cap forming a threaded housing 45 intended to accommodate the end of the screw 47. That is to say that the screw 47 is screwed directly. in a threaded portion of the cap or of a part integral with the cap. In this case, the tightening / loosening force is transmitted directly to the bonnet (collar 4) via the threads of the tapping. That is to say that the threaded portion forms a nut which cooperates with the screw 47.

La variante avec écrou des figures 4 à 6 permet cependant d'éviter une reprise d'usinage du chapeau.The variant with nut figures 4 to 6 However, it is possible to avoid re-machining the cap.

Pour améliorer le contrôle de la déformation du collier 4, le chapeau 1 peut comporter un deuxième dispositif de serrage/déserrage à vis/écrou tel que décrit ci-dessus ou d'un autre type connu. Par exemple, ce deuxième système de serrage/desserrage est disposé de façon diamétralement opposée au premier dispositif de serrage/désserage au niveau du collier.To improve the control of the deformation of the collar 4, the cap 1 may include a second screw / nut tightening / loosening device as described. above or another known type. For example, this second clamping / loosening system is arranged diametrically opposite to the first clamping / loosening device at the level of the collar.

Ce système de serrage/desserrage peut s'appliquer notamment à une structure de chapeau utilisant une bague de montage intermédiaire fendue formant une entité structurellement distincte du chapeau (cf. par exemple FR2900717A1 ).This tightening / loosening system can be applied in particular to a bonnet structure using a split intermediate mounting ring forming an entity structurally distinct from the bonnet (cf. for example FR2900717A1 ).
