Description

Chapeau de protection pour robinet de bouteille de fluide sous pression  Protective cap for pressurized fluid cylinder valve
La présente invention concerne un chapeau de protection pour robinet de bouteille de fluide sous pression ainsi qu'une bouteille pourvue d'un tel chapeau. The present invention relates to a protective cap for pressurized fluid bottle tap and a bottle provided with such a cap.
L'invention concerne plus particulièrement un chapeau de protection pour robinet de bouteille de fluide sous pression comprenant un corps dont une première extrémité est destinée à être montée sur une bouteille et dont une autre extrémité comporte un organe de préhension manuelle, l'organe de préhension étant monté mobile en rotation relativement au reste du corps du chapeau pour permettre le roulage d'une bouteille pourvue d'un tel chapeau en tenant manuellement la bouteille verticalement par l'organe de préhension.  The invention relates more particularly to a protective cap for a pressurized fluid bottle valve comprising a body whose first end is intended to be mounted on a bottle and whose other end comprises a manual gripping member, the gripping member being rotatably mounted relative to the remainder of the body of the cap to allow the rolling of a bottle provided with such a cap by manually holding the bottle vertically by the gripping member.
Les bouteilles de gaz industriel ou médical peuvent être difficiles à déplacer, même sur de courtes distances.  Industrial or medical gas cylinders can be difficult to move, even over short distances.
Une solution consiste à prévoir des roulettes à la base des bouteilles. Une autre solution consiste à utiliser des chariots à roulettes.  One solution is to provide casters at the base of the bottles. Another solution is to use trolleys with wheels.
Une autre solution adoptée par certains utilisateurs consiste à faire rouler les bouteilles par leur base. C'est-à-dire que l'opérateur maintient la bouteille avec une première main par le haut (où l'on trouve le plus souvent un chapeau de protection et parfois un pommeau) et roule la bouteille en la poussant avec le pied ou avec son autre main.  Another solution adopted by some users is to roll the bottles by their base. That is to say that the operator holds the bottle with a first hand from above (where we usually find a protective hat and sometimes a knob) and rolls the bottle by pushing with the foot or with his other hand.
Les différentes parties de la bouteille étant fixes, cette opération n'est pas aisée, surtout pour de nouveaux manipulateurs. En effet, l'opérateur doit régulièrement lâcher sa prise sur le haut de la bouteille ou tout du moins desserrer sa prise pour permettre la rotation de l'ensemble. Il y a donc un risque de faire chuter la bouteille.  The different parts of the bottle being fixed, this operation is not easy, especially for new manipulators. Indeed, the operator must regularly release its grip on the top of the bottle or at least loosen its grip to allow rotation of the whole. There is a risk of dropping the bottle.
Les documents FR2803366A1 ou W2007125240A1 mentionnent la possibilité de prévoir un pommeau tournant au sommet du chapeau d'une bouteille.  Documents FR2803366A1 or W2007125240A1 mention the possibility of providing a pommel turning at the top of the cap of a bottle.
Cependant, aucun de ces documents ne propose une solution technique qui soit à la fois simple, sûre, efficace et peu coûteuse.  However, none of these documents offers a technical solution that is simple, safe, effective and inexpensive.
Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus.  An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
A cette fin, le chapeau selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que l'organe de préhension est solidaire en rotation d'un axe tournant monté rotatif dans un palier fixe solidaire du corps du chapeau.  To this end, the cap according to the invention, moreover in conformity with the generic definition given in the preamble above, is essentially characterized in that the gripping member is integral in rotation with a rotatably mounted rotary shaft. in a fixed bearing secured to the body of the hat.
Par ailleurs, des modes de réalisation de l'invention peuvent comporter l'une ou plusieurs des caractéristiques suivantes : - l'axe tournant comporte une première extrémité située dans le volume de l'organe de préhension et une seconde extrémité située au moins en partie dans le corps du chapeau, Furthermore, embodiments of the invention may include one or more of the following features: - The rotating shaft has a first end located in the volume of the gripping member and a second end located at least partially in the body of the cap,
- la seconde extrémité de l'axe tournant est maintenue axialement sur le corps du chapeau via une pièce de blocage tel qu'un écrou monté sur la seconde extrémité de l'axe tournant,  the second end of the rotating axle is held axially on the body of the cap via a locking piece such as a nut mounted on the second end of the rotating axle,
- la seconde extrémité de l'axe tournant fait saillie au travers du corps du chapeau,  the second end of the rotating shaft protrudes through the body of the hat,
- le chapeau comporte un roulement situé entre l'axe tournant et le palier, le roulement comprenant au moins l'un parmi : une bague métallique montée libre entre l'axe et le palier, des billes,  the cap comprises a bearing located between the rotating shaft and the bearing, the bearing comprising at least one of: a metal ring mounted freely between the shaft and the bearing, balls,
- l'organe de préhension est surmoulé sur l'axe tournant,  the gripping member is overmolded on the rotating axis,
- l'organe de préhension comprend l'un au moins parmi, un pommeau, une protubérance, une poignée, un anneau,  the gripping member comprises at least one of, a knob, a protuberance, a handle, a ring,
- le palier est constitué de l'un au moins des matériaux parmi : un plastique, un matériau métallique tel que du zamak.  the bearing consists of at least one of: a plastic material, a metallic material such as zamak.
L'invention concerne également une bouteille de fluide sous pression comprenant un col sur lequel est monté un chapeau de protection conforme à l'une quelconque des caractéristiques ci-dessus ou ci-après.  The invention also relates to a bottle of pressurized fluid comprising a neck on which is mounted a protective cap according to any one of the above characteristics or hereafter.
L'invention peut concerner également tout dispositif ou procédé alternatif comprenant toute combinaison des caractéristiques ci-dessus ou ci-dessous.  The invention may also relate to any alternative device or method comprising any combination of the above or below features.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles :  Other particularities and advantages will appear on reading the following description, made with reference to the figures in which:
- la figure 1 représente une vue de côté d'une bouteille de fluide sous pression munie d'un chapeau à pommeau tournant selon un exemple de réalisation de l'invention,  FIG. 1 represents a side view of a pressurized fluid bottle provided with a rotating knob cap according to an exemplary embodiment of the invention,
- la figure 2 représente une vue en coupe, schématique et partielle, d'un détail de la figure 1 illustrant l'agencement du pommeau sur le corps du chapeau, FIG. 2 is a diagrammatic and partial sectional view of a detail of FIG. 1 illustrating the arrangement of the knob on the body of the cap,
- la figure 3 représente, de façon schématique et partielle, une vue perspective et en transparence du détail de la figure 1 . FIG. 3 schematically and partially shows a perspective and transparency view of the detail of FIG. 1.
La bouteille 6 de fluide sous pression représentée à la figure 1 comprend, montée sur son extrémité supérieure, un chapeau 5 de protection d'un robinet.  The bottle 6 of pressurized fluid shown in Figure 1 comprises, mounted on its upper end, a cap 5 for protecting a valve.
Par soucis de simplification, le robinet de la bouteille 6 n'est pas représenté. Classiquement, le robinet peut être vissé dans l'orifice taraudé de la bouteille 6. Le robinet est abrité au moins partiellement dans le chapeau 5.  For the sake of simplification, the valve of the bottle 6 is not shown. Conventionally, the valve can be screwed into the tapped opening of the bottle 6. The valve is housed at least partially in the cap 5.
Dans les exemples représentés aux figures le chapeau 5 a la forme générale d'une arche. Bien entendu, l'invention peut s'appliquer à toute autre géométrie de chapeau. Le chapeau 5 comprend un corps dont l'extrémité supérieure comporte un pommeau 1 de préhension manuelle. Le pommeau 1 a par exemple la forme générale d'un champignon. Bien entendu, tout autre forme et peut être envisagée. In the examples shown in the figures the hat 5 has the general shape of an arch. Of course, the invention can be applied to any other hat geometry. The cap 5 comprises a body whose upper end comprises a pommel 1 manual gripping. The knob 1 has for example the general shape of a mushroom. Of course, any other form and can be considered.
Le pommeau 1 est monté mobile en rotation relativement au reste du corps du chapeau 5 pour permettre le roulage de la bouteille 6 pourvue d'un tel chapeau 5 (en position montée, le chapeau 5 est solidaire en rotation de la bouteille 6).  The knob 1 is rotatably mounted relative to the rest of the body of the cap 5 to allow the rolling of the bottle 6 provided with such a cap 5 (in mounted position, the cap 5 is integral in rotation with the bottle 6).
Plus précisément, et comme visible aux figures 2 et 3, le pommeau 1 est solidaire en rotation d'un axe 2 tournant monté rotatif dans un palier 3 tubulaire fixe qui est solidaire du corps du chapeau 5.  More precisely, and as can be seen in FIGS. 2 and 3, the knob 1 is integral in rotation with a rotary shaft 2 rotatably mounted in a stationary tubular bearing 3 which is integral with the body of the cap 5.
Par exemple, l'axe 2 tournant comporte une première extrémité située dans le volume du pommeau 1 et une seconde extrémité située au moins en partie dans le corps du chapeau 5. Par exemple, le pommeau 1 est surmoulé sur l'axe 2 tournant.  For example, the rotating axis 2 has a first end located in the volume of the knob 1 and a second end located at least partly in the body of the cap 5. For example, the knob 1 is overmolded on the axis 2 rotating.
De même, le corps du chapeau 5 peut être surmoulé sur le palier 3.  Similarly, the body of the cap 5 can be overmolded on the bearing 3.
La seconde extrémité de l'axe 2 tournant peut traverser le corps du chapeau The second end of the rotating axis 2 can pass through the body of the hat
5 et faire saillie au travers de celui-ci. 5 and protrude through it.
La seconde extrémité de l'axe 2 tournant (et donc le pommeau 1 ) est maintenue axialement sur le corps du chapeau 5 via une pièce de blocage tel qu'un écrou 4 monté sur la seconde extrémité filetée de l'axe 2 tournant.  The second end of the rotating axis 2 (and therefore the knob 1) is held axially on the body of the cap 5 via a locking piece such as a nut 4 mounted on the second threaded end of the axis 2 rotating.
L'écrou 4 peut être associé à une rondelle de blocage. L'écrou 4 permet ainsi, en plus du maintien du pommeau 1 sur le corps du chapeau 5, un réglage du débattement axial possible du pommeau 1 par rapport au corps du chapeau 5.  The nut 4 can be associated with a locking washer. The nut 4 thus allows, in addition to maintaining the knob 1 on the body of the cap 5, an adjustment of the possible axial displacement of the knob 1 relative to the body of the cap 5.
Un ou des roulements peuvent être prévus entre l'axe 2 tournant et le palier 3, les roulements comprenant par exemple l'un parmi : une bague métallique montée libre entre l'axe et le palier, des billes...  One or more bearings may be provided between the rotating shaft 2 and the bearing 3, the bearings comprising for example one of: a metal ring mounted freely between the shaft and the bearing, balls ...
On conçoit donc aisément que la structure ci-dessus, tout en étant simple et peu coûteuse, permet un maintien et une rotation de la bouteille efficaces, même lorsque la bouteille est inclinée et génère des efforts transverses au niveau de l'axe de rotation.  It is therefore easy to understand that the above structure, while simple and inexpensive, allows maintenance and rotation of the bottle effective, even when the bottle is inclined and generates transverse forces at the axis of rotation.
Dans la variante de réalisation de la figure 4 le pommeau a pris la forme d'une poignée en forme de boucle fermée.  In the embodiment of Figure 4 the knob has taken the form of a closed loop-shaped handle.
