- This friction cone C is usually created at the point of contact PC between the deployable element 2 and the support part 6, that is to say at the point of contact of each pin 22 on the guide 23, 24 associated curve.

- ⁇ ( figure 6 ) is the angle between on the one hand said force F1 of the deployable element 2 on the support part 6, generated by the elastic element 16, and on the other hand the generator F2 of said friction cone C.
- N is a safety coefficient which is greater than 1.
- the operation of the deployment device 1, as described above, is as follows.
- the deployable element 2 namely the handle 4, being in the folded state P1, as shown in the figure 7 , an operator pushes or pulls on the deployable element 2 in the direction illustrated by the arrow H1.
- the deployment device 1 generates an automatic deployment of the deployable element 2 in the direction illustrated by the arrow H2, until bringing it into the deployed position P2 shown on the figure 9 .
- the pin 22 is located in the housing 24C, the deployed position P2 is stable and no final locking is necessary.
- deployment is understood to mean the displacement, by pivoting (or rotation over an arc of a circle) of the deployable element 2, from the folded position P1 to the deployed position P2.
- the deployable element 2 can be brought back by an operator from the deployed position P2 to the folded position P1, in particular for transporting the weapon system.
- said deployment device 1 generates rapid deployment of the deployment element 2, for example a handle 4, with reduced operator intervention (consisting simply in bringing the deployable element beyond said locking angle ) and partially automatic deployment.
- the deployment device 1 therefore allows rapid handling of the weapon system 3, for example a mobile firing station carried on the shoulder or any other element requiring the integration of a rapid and space-saving grip.
- the deployment device 1 also makes it possible to carry out an automatic positioning of the deployable element 2, in the deployed position P2, in which the weapon system 3 will be used, with a reduction in the number of movements of the operator who use it.
- the deployment device 1 makes it possible, by its design, to take up all (transverse) forces on the plane normal to the axis of the deployable element 2, during its use.
- the deployment device 1 makes it possible to block the deployable element 2 in the event of impacts, so to avoid untimely deployment.
- the number of components of the deployment device 1 is reduced, and this by more than 50% compared to a conventional device. This reduction in the number of components also makes it possible to reduce the cost of the deployment device 1.

Description
La présente invention concerne un dispositif de déploiement d'un élément déployable pour un système d'arme.The present invention relates to a device for deploying a deployable element for a weapon system.
Plus particulièrement, bien que non exclusivement, la présente invention s'applique à un système d'arme, en particulier à un poste de tir mobile, notamment du type porté à l'épaule, tel qu'un lance-missile ou un lance-roquette, qui nécessite une prise en main rapide, par le déploiement d'un élément de préhension, tel qu'une poignée par exemple.More particularly, although not exclusively, the present invention applies to a weapon system, in particular to a mobile firing station, in particular of the type carried on the shoulder, such as a missile launcher or a launcher. rocket, which requires rapid handling, by deploying a gripping element, such as a handle for example.
Une poignée d'un tel système d'arme présente un certain encombrement. Aussi, pour réduire cet encombrement, notamment lors du stockage et du transport du système d'arme lorsque ce dernier n'est pas utilisé, il est connu de prévoir une poignée qui est repliée dans cette situation, tout en étant dépoyable. Une telle poignée dépoyable est apte à être amenée de la position repliée à une position déployée stable pour son utilisation et la prise en main du système d'arme.A handle of such a weapon system has a certain bulk. Also, to reduce this size, especially during storage and transport of the weapon system when the latter is not used, it is known to provide a handle which is folded in this situation, while being expendable. Such a expendable handle is capable of being brought from the folded position to a stable deployed position for its use and the handling of the weapon system.
Afin de mettre en œuvre ce déploiement, on connaît un dispositif avec lequel un opérateur doit réaliser les opérations suivantes : appuyer sur un bouton pour réaliser un déverrouillage du mouvement de la poignée qui est initialement verrouillée dans la position repliée, puis déplacer la poignée, notamment par rotation, pour l'amener dans la position déployée, et enfin la verrouiller dans cette position déployée avant de pouvoir l'utiliser.In order to implement this deployment, a device is known with which an operator must carry out the following operations: press a button to unlock the movement of the handle which is initially locked in the folded position, then move the handle, in particular by rotation, to bring it into the deployed position, and finally lock it in this deployed position before it can be used.
Cette solution de déploiement usuelle nécessite donc une intervention relativement importante d'un opérateur et ne permet pas un déploiement très rapide.This usual deployment solution therefore requires a relatively large intervention by an operator and does not allow very rapid deployment.
Cette solution de déploiement usuelle n'est donc pas complètement satisfaisante.This usual deployment solution is therefore not completely satisfactory.
La présente invention a pour objet de remédier à cet inconvénient. Elle concerne un dispositif de déploiement d'un élément déployable (ou apte à être déployé) pour un système d'arme, permettant de mettre en œuvre un déploiement rapide, au moins partiellement automatique, avec une intervention réduite d'un opérateur.The object of the present invention is to remedy this drawback. It relates to a device for deploying a deployable element (or capable of being deployed) for a weapon system, making it possible to implement rapid deployment, at least partially automatic, with reduced intervention by an operator.
Selon l'invention, ledit dispositif de déploiement comporte une pièce de support, l'élément déployable est monté en rotation sur ladite pièce de support et est lié par l'intermédiaire d'au moins un élément élastique à ladite pièce de support, ledit élément déployable comporte au moins un pion, ledit pion étant apte à se déplacer le long d'un guide courbe de la pièce de support et à prendre l'une ou l'autre de deux positions stables respectivement dans deux logements prévus dans la pièce de support, ces positions stables correspondant respectivement à une position repliée et une position déployée de l'élément déployable, et au moins ledit guide et ledit élément élastique sont configurés pour générer un déploiement automatique de l'élément déployable jusqu'à ladite position déployée dès que l'élément déployable est soumis à une rotation (à partir de la position repliée vers la position déployée) dont l'angle est supérieur ou égal à un angle dit de déverrouillage.According to the invention, said deployment device comprises a support part, the deployable element is rotatably mounted on said support part and is connected by means of at least one elastic element to said support part, said element deployable comprises at least one pin, said pin being able to move along a curved guide of the support piece and to take one or the other of two stable positions respectively in two housings provided in the support piece , these stable positions corresponding respectively to a folded position and a deployed position of the deployable element, and at least said guide and said elastic element are configured to generate an automatic deployment of the deployable element to said deployed position as soon as the 'deployable element is subjected to a rotation (from the folded position to the deployed position) whose angle is greater than or equal to a so-called unlocking angle.
Ainsi, grâce à l'invention, dès que l'élément déployable est pivoté (par un opérateur) à partir de la position repliée, d'un angle correspondant audit angle de déverrouillage, le reste du déploiement jusqu'à ladite position déployée (à savoir une partie importante du déploiement) est réalisé automatiquement. De plus, comme cette position déployée (atteinte à la fin du déploiement automatique) est stable, aucun verrouillage final n'est nécessaire.Thus, thanks to the invention, as soon as the deployable element is pivoted (by an operator) from the folded position, by an angle corresponding to said unlocking angle, the rest of the deployment to said deployed position (at know a significant part of the deployment) is performed automatically. In addition, as this deployed position (reached at the end of automatic deployment) is stable, no final locking is necessary.
Par conséquent, ledit dispositif de déploiement permet un déploiement rapide de l'élément de déploiement, par exemple une poignée d'un lance-missile, avec une intervention réduite de l'opérateur (consistant simplement à amener l'élément déployable au-delà dudit angle de verrouillage) et un déploiement partiellement automatique.Consequently, said deployment device allows rapid deployment of the deployment element, for example a handle. a missile launcher, with reduced operator intervention (consisting simply of bringing the deployable element beyond said locking angle) and a partially automatic deployment.
Ledit dispositif de déploiement présente également d'autres avantages. En particulier, comme précisé davantage ci-dessous, il permet notamment de tenir des cas de charges en logistique et de reprendre tous les efforts transverses en utilisation, et il comprend un nombre réduit de composants.Said deployment device also has other advantages.

De plus, avantageusement, la pièce de support est munie de lames ressort au niveau de la ou des chevilles.Furthermore, advantageously, said deployable element is provided with at least one oblong slot, in which is mounted a dowel fixed to the support piece, to allow rotation of the deployable element on said support piece.

Le dispositif 1 illustrant l'invention et représenté sur la
La présente invention peut être appliquée à divers systèmes d'arme, et notamment à des systèmes d'arme portatifs, qui nécessitent le déploiement d'un élément déployable 2, et ceci notamment lors de son utilisation.The present invention can be applied to various weapon systems, and in particular to portable weapon systems, which require the deployment of a
Dans une application préférée, le système d'arme 3 correspond à un lance-roquette ou à un lance-missile, en particulier d'un missile anti-char ou d'un missile anti-aérien de courte portée. De plus, l'élément déployable 2 correspond, par exemple, à l'un des éléments suivants de ce système d'arme : un élément de préhension tel qu'une poignée notamment, une butée, un système de visée, par exemple une mire.In a preferred application, the
Dans l'exemple décrit ci-dessous, en référence aux
Ledit dispositif de déploiement 1 comporte également, comme représenté sur la
Cette pièce de support 6 peut être, soit une partie du système d'arme 3, soit une pièce indépendante qui est destinée à être fixée sur le système d'arme 3 par un moyen de fixation usuel.This
Comme représenté sur la
L'élément déployable 2 est monté sur la pièce de support 6, de manière à pouvoir pivoter. Pour ce faire, la pièce de support 6 comprend deux chevilles 10 et 11 (
Sur les
Dans la description suivante, l'adjectif interne est déterminé vers le plan de symétrie P, de part et d'autre dudit plan de symétrie P, comme illustré par des flèches I1 et I2 sur la
Dans la position assemblée de la
Le montage des chevilles 10 et 11 (fixées sur la pièce de support 6) dans les deux fentes oblongues 12 et 13 (de l'élément déployable 2) permet la rotation de l'élément déployable 2 par rapport à ladite pièce de support 6.The mounting of the
En outre, l'élément déployable 2 est lié par l'intermédiaire d'au moins un élément élastique 16 à ladite pièce de support 6. Dans l'exemple représenté sur les figures, l'élément élastique 16 est un ressort 17. Ce ressort 17 comporte une boucle 17A, 17B à chacune de ses extrémités longitudinales, comme représenté notamment sur les
Par ailleurs, l'élément déployable 2 comporte deux pions 22 représentés sur les
La pièce de support 6 comporte, en outre, deux guides 23 et 24 courbes. Les guides 23 et 24 courbes représentent, respectivement, des tronçons d'une partie du bord périphérique des branches 8 et 9 de la pièce de support 6, comme montré sur la
Chacun des guides 23 et 24 courbes comprend une partie 23A, 24A présentant une forme en arc de cercle. Cette partie 23A, 24A est définie entre deux logements, un logement 23B, 24B et un logement 23C, 24C. Ces logements 23B, 24B, 23C, 24C correspondent à des évidements arrondis pratiqués dans le bord périphérique des branches 8 et 9, de part et d'autre de la partie 23A, 24A en arc de cercle.Each of the
Chaque pion 22 est apte à se déplacer le long du guide 23, 24 courbe associé de la pièce de support 6 et à prendre l'une ou l'autre de deux positions stables, respectivement, dans l'un ou l'autre des deux logements (logement 23B, 24B d'une part et logement 23C, 24C d'autre part) prévus dans la pièce de support 6.Each
Ces positions stables correspondent, respectivement, à une position repliée P1 (
Dans un mode de réalisation particulier, la pièce de support 6 est munie de lames ressort 30 et 31 au niveau des chevilles 10 et 11, comme représenté sur la
En outre, comme représenté sur la
Par ailleurs, dans le mode de réalisation particulier représenté sur la
Le dispositif de déploiement 1, et notamment au moins ledit guide 23, 24 courbe et ledit élément élastique 16 sont configurés (c'est-à-dire formés et agencés) de manière à générer un déploiement automatique de l'élément déployable 2 jusqu'à ladite position déployée P2 (
Dans un mode de réalisation préféré, pour générer le déploiement automatique à partir de la position de déverrouillage P3 jusqu'à la position déployée P2, le dispositif de déploiement 1, et notamment les guides 23 et 24 courbes et l'élément élastique 16, sont configurés de sorte que la force F1 de l'élément déployable 2 sur la pièce de support 6, qui est générée par l'élément élastique 16, est toujours située à l'extérieur d'un cône de frottement C, comme représenté sur les
Ce cône de frottement C est créé, de façon usuelle, au point du contact PC entre l'élément déployable 2 et la pièce de support 6, c'est-à-dire au point de contact de chaque pion 22 sur le guide 23, 24 courbe associé. Ce point de contact PC se déplace donc lors de la rotation de l'élément déployable 2 par rapport à la pièce de support 6, comme illustré par une flèche J sur la
Plus précisément, pour générer le déploiement automatique, le dispositif de déploiement 1 et notamment les guides 23 et 24 courbes et l'élément élastique 16 sont configurés de sorte que l'inéquation suivante toujours est satisfaite : N.β<α,More specifically, to generate the automatic deployment, the
Dans cette inéquation, α (
Le fonctionnement du dispositif de déploiement 1, tel que décrit ci-dessus, est le suivant.The operation of the
L'élément déployable 2, à savoir la poignée 4, se trouvant dans l'état repliée P1, comme représenté sur la
De plus, comme dans cette position déployée P2, le pion 22 est situé dans le logement 24C, la position déployée P2 est stable et aucun verrouillage final n'est nécessaire.In addition, as in this deployed position P2, the
Ainsi, dès que l'élément déployable 2 est pivoté (par un opérateur) à partir de la position repliée P1, d'un angle correspondant audit angle de déverrouillage θ0, le reste du déploiement jusqu'à ladite position déployée P2 (à savoir une partie très importante du déploiement) est réalisé automatiquement.Thus, as soon as the
Dans le cadre de la présente invention, on entend par déploiement le déplacement, par pivotement (ou rotation sur un arc de cercle) de l'élément déployable 2, de la position repliée P1 à la position déployée P2. Bien entendu, après utilisation, l'élément déployable 2 peut être ramené par un opérateur de la position déployée P2 dans la position repliée P1, en particulier pour le transport du système d'arme.In the context of the present invention, deployment is understood to mean the displacement, by pivoting (or rotation over an arc of a circle) of the
Par conséquent, ledit dispositif de déploiement 1 génère un déploiement rapide de l'élément de déploiement 2, par exemple une poignée 4, avec une intervention réduite de l'opérateur (consistant simplement à amener l'élément déployable au-delà dudit angle de verrouillage) et un déploiement partiellement automatique.Consequently, said
Le dispositif de déploiement 1 permet donc une prise en main rapide du système d'arme 3, par exemple un poste de tir mobile porté sur l'épaule ou tout autre élément nécessitant l'intégration d'une préhension rapide et peu encombrante.The
Le dispositif de déploiement 1 permet également de réaliser une mise en position automatique de l'élément déployable 2, dans la position déployée P2, dans laquelle le système d'arme 3 sera utilisé, avec une réduction du nombre de mouvements de l'opérateur qui l'utilise.The
En outre, le dispositif de déploiement 1 permet, par sa conception, de reprendre tous les efforts (transverses) sur le plan normal à l'axe de l'élément déployable 2, lors de son utilisation.In addition, the
Par ailleurs, grâce à sa position repliée P1 qui est stable, en raison notamment de l'agencement des pions 22 dans les logements 23B et 24B, le dispositif de déploiement 1 permet de bloquer l'élément déployable 2 en cas de chocs, de manière à éviter un déploiement intempestif.Furthermore, thanks to its folded position P1 which is stable, in particular due to the arrangement of the
Il permet donc de tenir des cas de charges notamment en phase logistique (stockage et transport du système d'arme). Ceci permet d'empêcher le déploiement sous une certaine contrainte en phase logistique.It therefore makes it possible to hold charge cases, particularly in the logistics phase (storage and transport of the weapon system). This makes it possible to prevent deployment under a certain constraint in the logistics phase.
Par ailleurs, le nombre de composants du dispositif de déploiement 1 est réduit, et ceci de plus de 50 % par rapport à un dispositif usuel. Cette réduction du nombre de composants permet également de réduire le coût du dispositif de déploiement 1.Furthermore, the number of components of the
