Description

"Dispositif de fixation d'un modérateur d'onde de choc, modérateur d'onde de choc et arme à feu équipés du dispositif "Device for fixing a shock wave moderator, shock wave moderator and firearm equipped with the device
La présente invention concerne un dispositif de fixation d'un modérateur d'onde de choc sur au moins un canon d'une arme à feu.The present invention relates to a device for fixing a shock wave moderator on at least one barrel of a firearm.
Elle concerne également un modérateur d'onde de choc agissant sur le recul et sur l'intensité sonore et une arme à feu comprenant de ce dispositif de fixation. L'invention trouvera particulièrement son application pour l'équipement de fusils pour la pratique du tir sportif. En particulier, les pratiques de tir sportif ou de ball-trap destinées à un public plus large que d'habitude notamment les enfants et les femmes ou encore une pratique en intérieur sont visées par la présente invention. On connaît déjà différents types de modérateur d'onde de choc aptes à équiper des armes à feu et positionnés par enfilage sur le ou les canons du fusil.It also relates to a shock wave moderator acting on the recoil and on the sound intensity and a firearm comprising this fixing device. The invention will particularly find its application for the equipment of rifles for the practice of sport shooting. In particular, sport shooting or clay pigeon shooting practices intended for a wider audience than usual, in particular children and women, or even indoor practice are targeted by the present invention. There are already known different types of shock wave moderator capable of equipping firearms and positioned by threading on the barrel or barrels of the rifle.
Dans ce cadre, le document EP-A-0 772 758 présente un modérateur d'onde de choc pour fusil apte à modérer le son du fusil de ball-trap ou de loisir et adaptable sur le fusil. Ce dispositif comporte un corps tubulaire s'adaptant sur les canons de l'arme et comportant une chambre de décompression annulaire. Des pièces de centrage assurent la fixation par vissage et par l'extérieur du modérateur d'onde de choc sur les canons. Le demandeur a constaté que la pratique du tir sportif qui implique une utilisation répétée et à forte fréquence de l'arme à feu implique d'importantes sollicitations sur le fusil équipé du modérateur d'onde de choc, particulièrement en cisaillement, du fait du recul de l'arme, de échauffement, de chocs et des vibrations.In this context, the document EP-A-0 772 758 presents a shock wave moderator for a rifle capable of moderating the sound of a clay pigeon or recreational rifle and adaptable to the rifle. This device comprises a tubular body adapting to the barrels of the weapon and comprising an annular decompression chamber. Centering pieces ensure fixing by screwing and from the outside of the shock wave moderator on the barrels. The applicant noted that the practice of sport shooting which involves repeated and high frequency use of the firearm involves significant stress on the rifle equipped with the shock wave moderator, particularly in shear, due to the recoil weapon, overheating, shock and vibration.
Il existe actuellement un besoin de proposer des moyens de fixation de dispositif modérateur de son ou encore modérateur d'onde de choc sur le ou les canons d'une arme à feu disposant d'une grande résistance mécanique.There is currently a need to provide means for fixing a sound moderating device or else a shock wave moderator to the barrel or barrels of a firearm having high mechanical strength.
La présente invention apporte une solution à ce besoin en proposant un nouveau dispositif de fixation apportant une résistance mécanique accrue dans la solidarisation du modérateur d'onde de choc et des canons de l'arme à feu.The present invention provides a solution to this need by proposing a new fixing device providing increased mechanical strength in the connection of the shock wave moderator and the barrels of the firearm.
En particulier, une plus grande reprise du cisaillement est permis pas le dispositif.In particular, greater recovery of shear is allowed by the device.
Ce faisant, les éventuelles vis utilisées pour la solidarisation du modérateur d'onde de choc du dispositif de fixation ne sont plus sollicitées en cisaillement ce qui augmente la durée de vie et la sécurité de l'ensemble au cours de l'utilisation.In doing so, any screws used for securing the shock wave moderator to the fixing device are no longer subjected to shear, which increases the service life and safety of the assembly during use.
D'autres buts et avantages apparaîtront au cours de la description qui suit d'un mode préféré de réalisation de l'invention qui n'est cependant pas limitatif.Other objects and advantages will appear during the following description of a preferred embodiment of the invention which is not, however, limiting.
La présente invention concerne un dispositif de fixation d'un modérateur d'onde de choc sur au moins un canon d'une arme à feu comprenant des moyens de maintien du canon et des moyens de fixation sur le corps du modérateur d'onde de choc caractérisé par le fait qu'il comporte une pièce d'appui apte à s'appliquer sur une surface du corps du modérateur d'onde de choc orientée transversalement par rapport à son sens long, pour la transmission des efforts longitudinaux au modérateur d'onde de choc.The present invention relates to a device for fixing a shock wave moderator on at least one barrel of a firearm comprising means for retaining the barrel and means for fixing to the body of the shock wave moderator characterized by the fact that it comprises a support piece capable of being applied to a surface of the body of the shock wave moderator oriented transversely with respect to its long direction, for the transmission of the longitudinal forces to the wave moderator of choc.
Ce dispositif peut se présenter suivants les variantes préférées introduites ci-après : - il présente deux flancs encadrant le canon et une entretoise intercalée entre les deux flancs ;This device can be presented according to the preferred variants introduced below: - it has two sides flanking the barrel and a spacer interposed between the two sides;

- les moyens de fixation sont des vis ou des rivets ; - la pièce d'appui comporte une surface d'application sur le canon- The fixing means are screws or rivets; - the support piece has an application surface on the barrel
L'invention concerne également un modérateur d'onde de choc pour arme à feu comportant un corps montable sur au moins un canon de l'arme à feu qui comporte au moins un dispositif de fixation.. Avantageusement, ce modérateur d'onde de choc est tel que le corps comporte un trou traversé par la pièce d'appui et que le bord du trou constitue la surface d'application de la pièce d'appui.The invention also relates to a shock wave moderator for a firearm comprising a body mountable on at least one barrel of the firearm which comprises at least one fixing device. Advantageously, this shock wave moderator is such that the body has a hole through which the support piece passes and that the edge of the hole constitutes the application surface of the support piece.
L'invention concerne également une arme à feu caractérisée en ce qu'elle comporte un modérateur d'onde de choc selon l'invention. A titre préféré, cette arme à feu comporte deux canons et le dispositif de fixation comporte une entretoise intercalée entre des deux canons.The invention also relates to a firearm characterized in that it comprises a shock wave moderator according to the invention. Preferably, this firearm comprises two barrels and the fixing device comprises a spacer interposed between two barrels.
Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément. La figure 2 est une vue de côté d'un fusil équipée d'un modérateur d'onde de choc et comportant un dispositif de fixation, sans pièce d'appui.The attached drawings are given by way of examples and are not limitative of the invention. They represent only one embodiment of the invention and will make it easy to understand it. FIG. 2 is a side view of a rifle equipped with a shock wave moderator and comprising a fixing device, without support piece.
La figure 1 en est une vue en coupe selon les lignes A-A.Figure 1 is a sectional view along lines A-A.
La figure 4 est une vue partielle de côté d'un fusil équipée d'un modérateur d'onde de choc et disposant d'un dispositif de fixation selon l'invention avec une pièce d'appui.Figure 4 is a partial side view of a rifle equipped with a shock wave moderator and having a fixing device according to the invention with a support piece.
La figure 3 illustre le montage de la pièce d'appui sur le reste du dispositif de fixation en coupe selon les lignes B-B de la figure 4.FIG. 3 illustrates the mounting of the support piece on the rest of the fixing device in section along lines B-B of FIG. 4.
On a représenté aux figures 1 à 4 un exemple de coopération d'un modérateur d'onde de choc 3 et d'une arme à feu 1 ici sous forme de fusil. A cet effet, le modérateur d'onde de choc 3 comporte un corps 8, généralement de section cylindrique creuse et apte à être positionné autour du ou des canons 2a, 2b de l'arme 1.FIGS. 1 to 4 show an example of cooperation between a shock wave moderator 3 and a firearm 1 here in the form of a rifle. To this end, the shock wave moderator 3 comprises a body 8, generally of hollow cylindrical section and able to be positioned around the barrel (s) 2a, 2b of the weapon 1.
Dans le cas illustré, deux canons superposés sont présents.In the illustrated case, two superimposed guns are present.
La fixation du modérateur d'onde de choc 3 nécessite une grande résistance mécanique de la solidarisation ainsi qu'un parfait centrage sur les canons 2a, 2b.The fixing of the shock wave moderator 3 requires great mechanical strength of the connection as well as perfect centering on the barrels 2a, 2b.
A cet effet, le dispositif de fixation de l'invention comporte deux flan cs 6a, 6b, positionné chacun de part et d'autre des canons 2a, 2b pour les encadrer. Une constitution symétrique des flancs 6a, 6b peut convenir. Dans l'espace interstitiel entre les canons superposés 2a, 2b, une entretoise 5 est intercalée de façon à rejoindre les flancs 6a, 6b et à maintenir un écartement fixe entre ces deux flancs.To this end, the fixing device of the invention comprises two blanks cs 6a, 6b, each positioned on either side of the barrels 2a, 2b to frame them. A symmetrical constitution of the sides 6a, 6b may be suitable. In the space interstitial between the superimposed barrels 2a, 2b, a spacer 5 is interposed so as to join the sides 6a, 6b and to maintain a fixed spacing between these two sides.
Avantageusement, cette entretoise est installée au moment de la fabrication des canons et elle est solidarisée à chacun d'eux par électrosoudure.Advantageously, this spacer is installed at the time of manufacture of the barrels and it is secured to each of them by electrofusion.
Une solidarisation par vissage est avantageusement prévue entre chacun des flans 6a, 6b et l'entretoise 5 tel que cela ressort particulièrement des figures 1 et 3. La combinaison des flancs 6a, 6b et de l'entretoise 5 est apte à maintenir parfaitement les canons 2a, 2b. En outre, une surface d'appui de l'entretoise 5 sur chacun des canons 2a, 2b est prévue et est représentée sous forme incurvée aux figures 1 et 3.A fastening by screwing is advantageously provided between each of the blanks 6a, 6b and the spacer 5 as is particularly apparent from Figures 1 and 3. The combination of the sides 6a, 6b and the spacer 5 is able to perfectly maintain the barrels 2a, 2b. In addition, a bearing surface of the spacer 5 on each of the barrels 2a, 2b is provided and is shown in curved form in FIGS. 1 and 3.
D'autre part, le dispositif de fixation est solidarisé au corps 8 du modérateur d'onde de choc 3.On the other hand, the fixing device is secured to the body 8 of the shock wave moderator 3.
Dans ce cadre, des vis 7 pourront constituer des moyens d'encastrement du dispositif de fixation sur le corps 8.In this context, screws 7 could constitute means for embedding the fixing device on the body 8.
A titre d'exemple, aux figures 1 et 3, deux vis assurent le montage de chaque flan 6a, 6b sur le corps 8. Selon l'invention, une pièce d'appui 9 est en outre constituée afin de reprendre une grande partie des efforts imposés sur le dispositif de fixation lors du fonctionnement de l'arme à feu et pour les transmettre au corps du modérateur d'onde de choc.By way of example, in FIGS. 1 and 3, two screws ensure the mounting of each blank 6a, 6b on the body 8. According to the invention, a support piece 9 is also formed in order to take up a large part of the forces imposed on the fixing device during the operation of the firearm and to transmit them to the body of the shock wave moderator.
Dans ce cadre, une pièce d'appui 9 est rapportée sur le reste du dispositif de fixation, par exemple par vissage, tel que cela ressort de la figure 3.In this context, a support piece 9 is attached to the rest of the fixing device, for example by screwing, as can be seen in FIG. 3.
En correspondance de la pièce d'appui 9, un trou est formé dans le corps 8 du modérateur d'onde de choc 3 pour permettre à la pièce 9 de traverser ledit corps 8 pour sa fixation sur le dispositif. La pièce d'appui 9, dans cette position traversante, est apte à s'appliquer sur les bords du trou formé dans le corps 8. Cette surface d'application permet la transmission des efforts vers le corps 8 dont la masse est largement suffisante pour supporter les contraintes appliquées. La pièce d'appui 9 peut être soit en matière synthétique (tel de l'Ergal 55) soit en aluminium.In correspondence with the support piece 9, a hole is formed in the body 8 of the shock wave moderator 3 to allow the piece 9 to pass through said body 8 for its attachment to the device. The support piece 9, in this through position, is capable of being applied to the edges of the hole formed in the body 8. This application surface allows the transmission of forces to the body 8, the mass of which is largely sufficient for bear the constraints applied. The support piece 9 can either be made of synthetic material (such as Ergal 55) or aluminum.
La pièce d'appui 9 permet également de renforcer la fixation du modérateur d'onde de choc 3 sur les canons 2a, 2b en disposant d'une surface d'application 10 sur un canon.The support piece 9 also makes it possible to strengthen the attachment of the shock wave moderator 3 to the barrels 2a, 2b by having an application surface 10 on a barrel.
Un modérateur d'onde de choc 3 peut être équipé d'un ou de plusieurs dispositifs ainsi présentés selon la nécessité. Pour des questions d'alignement et de maintien, au moins deux dispositifs pourront s'avérer utile dans la pratique. L'invention concerne enfin une arme à feu équipée d'un modérateur d'onde de choc du type précédemment décrit et comportant un dispositif de fixation.A shock wave moderator 3 can be equipped with one or more devices thus presented as required. For alignment and maintenance purposes, at least two devices may prove useful in practice. Finally, the invention relates to a firearm equipped with a shock wave moderator of the type described above and comprising a fixing device.
Deux dispositifs sont avantageusement formés sur la longueur du canon, l'un juste avant la bouche du canon, l'autre, postérieur juste avant le garde- main. Two devices are advantageously formed over the length of the barrel, one just before the muzzle, the other, posterior just before the handguard.
