Description

BRAS ÉQUILIBREUR POUR UN FUSIL DE PRÉCISION  BALANCING ARM FOR A PRECISION GUN
La présente invention concerne un bras équilibreur pour un fusil et notamment pour un fusil de précision. The present invention relates to a balancing arm for a rifle and in particular for a sniper rifle.
Lors d'une intervention, notamment de forces de sécurité armées, l'un des composants est la présence d'un tireur d'élite qui, grâce à une arme de précision et de longue portée, peut neutraliser à distance des cibles.  During an intervention, including armed security forces, one of the components is the presence of a sniper who, with a precision weapon and long range, can remotely neutralize targets.
Pour ce faire, le tireur d'élite avec son arme peut être embarqué sur un véhicule terrestre, aérien ou nautique.  To do this, the sniper with his weapon can be embarked on a land, air or water vehicle.
Or, il s'avère que les moyens de support de l'arme du tireur d'élite en question sont relativement peu adaptés, voire inexistants, si bien que le gain opérationnel qui peut exister à disposer d'un tireur d'élite se trouve annulé du fait de l'absence de moyens adéquats qui lui permettent d'utiliser son arme à son entière capacité.  However, it turns out that the means of support of the sniper's weapon in question are relatively unsuitable or non-existent, so that the operational gain that may exist to have a sniper is found canceled because of the lack of adequate means that allow him to use his weapon to his full capacity.
Dans ce contexte technique, la présente invention a pour objet de permettre l'utilisation d'une arme de précision, et notamment un fusil de précision sur un véhicule.  In this technical context, the present invention aims to allow the use of a precision weapon, including a sniper on a vehicle.
A cet effet, la présente invention a pour objet un bras équilibreur pour un fusil de précision destiné à être fixé sur un véhicule, caractérisé en ce que le bras équilibreur comprend un élément proximal présentant une articulation en pivot sur un élément distal supportant à son extrémité libre des moyens de réception d'un fusil. For this purpose, the subject of the present invention is a balancing arm for a precision shotgun intended to be fixed on a vehicle, characterized in that the balancing arm comprises a proximal element having a pivot articulation on a distal element supporting at its end free means of receiving a rifle.
Ainsi, le bras équilibreur selon l'invention offre la possibilité d'équilibrer une charge utile qu'il supporte, comme un fusil, en vue d'améliorer la capacité à stabiliser le fusil par un tireur d'élite.  Thus, the balancing arm according to the invention offers the possibility of balancing a payload that it supports, such as a rifle, in order to improve the ability to stabilize the rifle by a sniper.
Selon un mode de réalisation, l'élément distal et l'élément proximal présentent une structure en parallélogramme déformable.  According to one embodiment, the distal element and the proximal element have a deformable parallelogram structure.
Avantageusement, l'élément distal et l'élément proximal présentent chacun une première chape dotée d'une liaison pivot basse et d'une liaison pivot haute et une seconde chape dotée d'une liaison pivot basse et d'une liaison pivot haute reliées entre elles par un carter qui est fixé à la liaison pivot basse de la première chape et à la liaison pivot basse de la deuxième chape et au moins un tube de structure qui est fixé à la liaison pivot haute de la première chape et à la liaison pivot haute de la deuxième chape et par un vérin qui est fixé diagonalement entre la liaison pivot basse de la première chape et la liaison pivot haute de la deuxième chape. Selon une forme d'exécution, le bras équilibreur comprend une entretoise qui assure l'articulation de l'élément proximal sur l'élément distal. Advantageously, the distal element and the proximal element each have a first clevis having a low pivot connection and a high pivot connection and a second clevis having a low pivot connection and a high pivot connection connected between they are provided by a casing which is fixed to the low pivot connection of the first clevis and to the low pivot connection of the second clevis and at least one structural tube which is fixed to the high pivot connection of the first clevis and to the pivot connection high of the second yoke and by a cylinder which is fixed diagonally between the low pivot connection of the first yoke and the high pivot connection of the second yoke. According to one embodiment, the balancing arm comprises a spacer which ensures the articulation of the proximal element on the distal element.
De manière avantageuse, la seconde chape de l'élément proximal et la première chape de l'élément distal présentent chacune des pattes sur lesquelles l'entretoise vient se fixer.  Advantageously, the second clevis of the proximal element and the first clevis of the distal element each have tabs on which the spacer is fixed.
Selon une possibilité, le bras équilibreur comprend une plateforme équipée d'un fourreau dans lequel est insérée une broche solidaire de l'élément proximal.  According to one possibility, the balancing arm comprises a platform equipped with a sleeve in which is inserted a pin integral with the proximal element.
Selon un autre aspect de l'invention, celle-ci concerne également un véhicule, notamment véhicule aérien, terrestre ou nautique, comprenant un bras équilibreur ayant les caractéristiques précitées.  According to another aspect of the invention, it also relates to a vehicle, in particular air, land or water vehicle, comprising a balancing arm having the aforementioned characteristics.
Pour sa bonne compréhension, l'invention est décrite en référence aux dessins ci annexés représentant, à titre d'exemple non limitatif, une forme de réalisation d'un bras équilibreur selon l'invention. For a good understanding, the invention is described with reference to the accompanying drawings showing, by way of non-limiting example, an embodiment of a balancing arm according to the invention.
Figure 1 montre en perspective un bras équilibreur équipé d'un fusil de précision,  Figure 1 shows in perspective a balancing arm equipped with a sniper rifle,
Figure 2 est une vue en plan du bras équilibreur,  Figure 2 is a plan view of the balancing arm,
Figure 3 montre le bras équilibreur isolé de sa plateforme et de son interface de réception d'un fusil,  Figure 3 shows the isolated balancing arm of its platform and its receiving interface of a rifle,
Figures 4 et 5 montrent deux sous éléments du bras équilibreur sur lesquels les carters de protection ont été ôtés.  Figures 4 and 5 show two sub-elements of the balancer arm on which the protective housings have been removed.
On peut se reporter tout d'abord à la figure 2 qui montre la structure du bras équilibreur 1 selon l'invention. Le bras équilibreur 1 équilibre une charge utile qu'il supporte, comme un fusil, cela ayant pour conséquence le cas échéant d'améliorer la capacité à stabiliser le fusil par le tireur d'élite.  We can first refer to Figure 2 which shows the structure of the balancer arm 1 according to the invention. The balancer arm 1 balances a payload that it supports, such as a rifle, which consequently has the consequence of improving the ability of the sniper to stabilize the rifle.
Comme on peut le voir sur cette figure, le bras équilibreur 1 présente deux éléments articulés à savoir un élément proximal 2 et un élément distal 3. L'élément proximal 2 et l'élément distal 3 présentent une architecture sensiblement identique.  As can be seen in this figure, the balancing arm 1 has two articulated elements namely a proximal element 2 and a distal element 3. The proximal element 2 and the distal element 3 have a substantially identical architecture.
L'élément proximal 2 présente une première 5 chape sur laquelle est fixée une broche 6 et une seconde chape 7. Comme le montre la Figure 4, l'architecture de l'élément proximal 2 comprend deux tubes 8 et un vérin 9 à gaz. Elle peut également comprendre un ressort 1 1 associé au vérin 9 pour permettre un réglage plus fin. De façon plus générale, l'architecture de l'élément proximal 2 peut comprendre deux tubes 8 et des moyens de compensation, comme le vérin 9 et/ou le ressort 1 1 , pour compenser le poids de la charge, notamment du fusil, supportée par le bras équilibreur 1 . Le vérin 9, tout comme les deux tubes 8, sont reliés sur chacune des deux chapes 5 et 7 par des liaisons pivots. Les liaisons pivots assurant la fixation du vérin et des deux tubes 8 peuvent être formées par des axes dont les extrémités sont filetées et sur lesquelles viennent se fixer des écrous. The proximal member 2 has a first yoke 5 on which is fixed a pin 6 and a second yoke 7. As shown in Figure 4, the architecture of the proximal member 2 comprises two tubes 8 and a cylinder 9 gas. It may also include a spring 1 1 associated with the cylinder 9 to allow a finer adjustment. More generally, the architecture of the proximal element 2 may comprise two tubes 8 and compensation means, such as the jack 9 and / or the spring 1 1, to compensate for the weight of the load, particularly the rifle, which is supported. by the balancing arm 1. The jack 9, like the two tubes 8, are connected to each of the two yokes 5 and 7 by pivot links. Pivot connections ensuring the attachment of the cylinder and the two tubes 8 may be formed by pins whose ends are threaded and on which are fixed nuts.
II est à noter qu'au niveau de la seconde chape 7 de l'élément proximal 2, l'extrémité du vérin à gaz et l'extrémité des tubes sont concourantes.  It should be noted that at the second clevis 7 of the proximal element 2, the end of the gas cylinder and the end of the tubes are concurrent.
En d'autres termes, une unique liaison pivot P assure la liaison respectivement de l'extrémité des tubes et de l'extrémité du vérin à gaz.  In other words, a single pivot connection P provides the connection respectively of the end of the tubes and the end of the gas cylinder.
La figure 4 sur laquelle le carter a été ôté fait ressortir cette disposition technique de l'invention.  Figure 4 on which the housing has been removed highlights this technical provision of the invention.
Un carter 10 vient capoter l'élément proximal 2. Comme cela apparaît sur la figure, le carter 10 est fixé sur la première chape 5 par une liaison pivot et sur la seconde chape 7 par une liaison pivot.  A casing 10 dislodges the proximal element 2. As shown in the figure, the housing 10 is fixed on the first yoke 5 by a pivot connection and on the second yoke 7 by a pivot connection.
Ainsi, la première chape 5 est dotée d'une liaison pivot basse P1 et d'une liaison pivot haute P2 et la seconde chape est dotée d'une liaison pivot haute P3 et d'une liaison pivot haute P4. Le carter 10 est fixé à la liaison pivot basse P1 et à la liaison pivot basse P3 et les tubes de structure sont fixés à la liaison pivot haute P2 et à la liaison pivot haute P4. Le vérin 9 est fixé diagonalement entre la liaison pivot basse P1 de la première chape et la liaison pivot haute P4 de la deuxième chape  Thus, the first yoke 5 is provided with a low pivot connection P1 and a high pivot connection P2 and the second yoke is provided with a high pivot connection P3 and a high pivot connection P4. The casing 10 is fixed to the low pivot connection P1 and to the low pivot connection P3 and the structural tubes are fixed to the high pivot connection P2 and to the high pivot connection P4. The jack 9 is diagonally fixed between the low pivot connection P1 of the first clevis and the high pivot connection P4 of the second clevis
Ainsi, le bras proximal 2 se comporte comme un parallélogramme déformable.  Thus, the proximal arm 2 behaves as a deformable parallelogram.
L'élément distal 3 présente une architecture similaire à celle de l'élément proximal 2.  The distal element 3 has an architecture similar to that of the proximal element 2.
Ainsi, dans l'élément distal 3, on trouve une première chape 13 et une seconde chape 14 entre lesquelles s'étendent un ou plusieurs tubes 15 et un vérin 16 ; au niveau de la première chape, le vérin 16 est fixé par une liaison pivot indépendante de celle qui assure la fixation du ou des tubes et, au niveau de la deuxième extrémité, le vérin 16 est fixé sur la même liaison pivot que celle qui relie les tubes à la seconde chape.  Thus, in the distal element 3, there is a first yoke 13 and a second yoke 14 between which extend one or more tubes 15 and a jack 16; at the first yoke, the jack 16 is fixed by a pivot connection independent of that which secures the tube or tubes and, at the second end, the jack 16 is fixed on the same pivot connection as that which connects the tubes to the second screed.
La première chape 13 est dotée d'une liaison pivot basse P5 et d'une liaison pivot haute P6 et la seconde chape 14 est dotée d'une liaison pivot basse P7 et d'une liaison pivot haute P8. Un carter 19 est fixé à la liaison pivot basse P5 et à la liaison pivot basse P7 et le tube de structure 15 est fixé à la liaison pivot haute P6 et à la liaison pivot haute P8. Le vérin 9 est fixé diagonalement entre la liaison pivot basse P5 de la première chape 13 et la liaison pivot haute P8 de la deuxième chape 14. La liaison entre l'élément proximal 2 et l'élément distal 3 se fait par une entretoise 20, c'est-à-dire par une plaque métallique qui permet l'articulation de l'élément distal 3 sur l'élément proximal 2. The first yoke 13 is provided with a low pivot connection P5 and a high pivot connection P6 and the second yoke 14 is provided with a low pivot connection P7 and a high pivot connection P8. A housing 19 is attached to the low pivot link P5 and the low pivot link P7 and the structural tube 15 is attached to the high pivot link P6 and the high pivot link P8. The jack 9 is diagonally fixed between the low pivot connection P5 of the first yoke 13 and the high pivot connection P8 of the second yoke 14. The connection between the proximal element 2 and the distal element 3 is by a spacer 20, that is to say by a metal plate which allows the articulation of the distal element 3 on the proximal element 2.
Pour cela, la seconde chape de l'élément proximal 2 et la première chape de l'élément distal 3 sont chacune dotées de deux pattes 21 et 22 dans lesquelles viennent s'engager des axes permettant une libre rotation.  For this, the second clevis of the proximal element 2 and the first clevis of the distal element 3 are each provided with two lugs 21 and 22 in which are engaged axes for free rotation.
La figure 3 montre le bras équilibreur 1 équipé de ses carters.  Figure 3 shows the balancer arm 1 equipped with its housings.
Comme on peut le voir sur cette figure, aucune protubérance ne vient dépasser du bras et il peut donc pivoter par rapport à sa broche 6 de fixation par rapport à l'axe Z.  As can be seen in this figure, no protuberance protrudes beyond the arm and can therefore pivot relative to its fixing pin 6 relative to the Z axis.
Si l'on se réfère au différentiel X, Y, Z présent sur la figure 3, chacun des éléments distal 2 et proximal 3 peut pivoter par rapport à un plan Y, Z qui est le plus souvent le plan vertical.  Referring to the X, Y, Z differential present in FIG. 3, each of the distal 2 and proximal 3 elements may pivot relative to a Y, Z plane which is most often the vertical plane.
Il est également possible de rabattre l'élément distal 3 contre l'élément proximal 2.  It is also possible to fold the distal member 3 against the proximal element 2.
On peut se reporter à la figure 1 pour voir le bras équilibreur 1 en situation. Sur cette figure, il apparaît que la broche 6 est engagée dans un fourreau 25 qui est solidaire d'une tôle 26 qui peut être embarquée dans un véhicule.  We can refer to Figure 1 to see the balancer arm 1 in situation. In this figure, it appears that the pin 6 is engaged in a sleeve 25 which is integral with a plate 26 which can be embedded in a vehicle.
A l'extrémité libre du bras équilibreur 1 , il est prévu qu'une platine de réception 27 avec un fusil 28 soit positionnée sur la seconde chape de l'élément distal 3.  At the free end of the balancer arm 1, it is provided that a receiving plate 27 with a gun 28 is positioned on the second yoke of the distal member 3.
En configuration d'utilisation, tel qu'on peut le voir sur la figure 1 , le bras équilibreur est configuré de telle sorte que l'élément distal 3 et l'élément proximal 2 forment un V.  In the use configuration, as can be seen in FIG. 1, the balancing arm is configured such that the distal member 3 and the proximal member 2 form a V.
Cela permet à l'opérateur de faire pivoter son fusil 28 sur une plage angulaire importante.  This allows the operator to rotate his rifle 28 over a large angular range.
L'apport de l'invention se situe dans le fait que l'utilisateur peut déployer le bras équilibreur 1 , tout simplement en exerçant une poussée sur son fusil  The contribution of the invention lies in the fact that the user can deploy the balancer arm 1, simply by exerting a thrust on his rifle
- dans un plan XY horizontal en utilisant la capacité des éléments distal 2 et proximal à pivoter l'un par rapport à l'autre,  in a horizontal XY plane using the capacity of the distal and proximal elements to pivot relative to each other,
- dans un plan YZ vertical en utilisant la capacité des parallélogrammes formés par les liaisons pivot, les tubes et le vérin de l'élément proximal 2 et de l'élément distal 3,  in a vertical YZ plane using the capacity of the parallelograms formed by the pivot links, the tubes and the cylinder of the proximal element 2 and of the distal element 3,
- dans une combinaison de mouvement dans les plans XY et YZ.  - in a combination of motion in the XY and YZ planes.
En agissant de la sorte, l'élément distal 3 et l'élément proximal 2 se déplient et permettent à l'opérateur une amplitude très importante. L'opérateur peut également disposer d'une amplitude dans un plan Y, Z puisqu'en exerçant une traction sur son fusil, le bras équilibreur 1 , grâce à ses vérins, va pouvoir se mouvoir et accompagner les gestes de l'opérateur dans le plan Y, Z. By acting in this way, the distal element 3 and the proximal element 2 unfold and allow the operator a very large amplitude. The operator can also have an amplitude in a plane Y, Z since by exerting a pull on his rifle, the balancing arm 1, thanks to its jacks, will be able to move and accompany the operator's gestures in the plan Y, Z.
On voit donc que l'invention permet d'offrir, à un opérateur se servant d'un fusil de précision, une extrême liberté de mouvement.  It can therefore be seen that the invention makes it possible to offer an operator using a sniper rifle an extreme freedom of movement.
Par ailleurs, et contrairement à l'état de la technique, le fusil est en permanence supporté par un bras. Ainsi, l'opérateur est déchargé du poids de son fusil et peut se concentrer pendant de longues périodes sur sa ou ses cibles.  Moreover, and contrary to the state of the art, the rifle is permanently supported by an arm. Thus, the operator is relieved of the weight of his rifle and can concentrate for long periods on his or her targets.
On notera ainsi que le bras équilibreur est destiné à supporter le poids de l'arme en offrant une grande liberté de mouvement à l'utilisateur, en éliminant la transmission des perturbations produites par le véhicule à l'armement, et en éliminant la transmission des efforts de recul aux véhicule et notamment aux points de fixation.  It should be noted that the balancing arm is intended to support the weight of the weapon by providing great freedom of movement to the user, eliminating the transmission of disturbances produced by the vehicle when arming, and eliminating the transmission of recoil efforts to the vehicles and in particular to the fixing points.
On notera également que le véhicule équipé du bras équilibreur 1 peut correspondre à un véhicule aérien, terrestre ou nautique.  It will also be noted that the vehicle equipped with the balancer arm 1 may correspond to an air, land or water vehicle.
Bien que cela ne soit représenté, le bras équilibreur 1 peut comprendre des moyens d'immobilisation, comme une bride, une sangle ou des ergots, destinés à immobiliser le bras équilibreur 1 , et l'arme qu'il supporte, dans une ou plusieurs positions de sécurité prédéterminée(s), afin d'empêcher le déplacement de l'arme en-dehors des périodes d'utilisation au tir.  Although not shown, the balancing arm 1 may comprise immobilizing means, such as a flange, a strap or lugs, intended to immobilize the balancer arm 1, and the weapon that it supports, in one or more predetermined safety positions, to prevent the movement of the weapon outside the periods of use in shooting.
Le bras équilibreur 1 peut également comprendre des moyens pour limiter la course angulaire des mouvements de rotation, notamment des éléments proximal 2 et distal 3 par rapport à l'entretoise 20, comme une butée, afin d'éviter que le canon de l'arme puisse être accidentellement orienté vers le véhicule équipé du bras équilibreur 1 .  The balancer arm 1 may also comprise means for limiting the angular travel of the rotational movements, in particular of the proximal 2 and distal 3 elements relative to the spacer 20, as a stop, in order to prevent the barrel of the weapon may be accidentally directed to the vehicle equipped with the balancing arm 1.
Bien entendu, l'invention n'est pas limitée à la forme de réalisation ci annexée mais elle en embrasse au contraire toutes les variantes de réalisation.  Of course, the invention is not limited to the embodiment herein appended but embraces all variants thereof.
