    Firearm pointing device interface
    [0001] The invention relates to the mastery of aiming devices for firearms.
    [0002] There are many aiming devices available in the market. These devices can, for example, be installed on a gun or on a rifle.
    [0003] However, most of these devices cannot be used directly on a machine gun. Indeed, the recoil of the weapon and the vibrations generated at the time of a shot are such that, in most cases, the viewfinder is damaged from the first burst of shots. In addition, certain machine guns are intended to be fixed on a maritime, land or air vehicle that generates additional vibrations and accelerations. To partially solve these problems, US4026054 is known, which describes an interface suitable for fixing on a weapon and for positioning between this weapon and a sight glass, where this interface is suitable for damping the accelerations suffered by the viewfinder at the time of a shot and / or at the time of a movement of the vehicle on which the submachine gun is mounted.
    [0004] This interface includes:
    • A first part suitable for fixing on a weapon,
    • A second mobile part with respect to the first part,
    • Damping means with springs of displacement of the second part with respect to the first part,
    • An upper part comprising suitable means to allow the fixing of a telescope or a camera,
    • Means suitable for regulating the inclination of the upper part with respect to the second part.
    [0005] Thus, at the time of a shot, the weapon will move backwards with significant acceleration while the spring-damping means retain the viewfinder so that it undergoes less acceleration with respect to that of the weapon.
    [0006] US2004 / 0016169 has a similar mounting interface. Such a device is perfect for implementing a pointing device of a few tens of grams. On the other hand, it is not feasible to use it for a pointing device with a mass greater than 500 grams. Indeed, in such a case, it would be necessary to use very large diameter springs that would require a distance from the aiming device with respect to the barrel of the weapon and, therefore, a significant decrease in accuracy at close range.
    [0007] The objective of the invention is to solve this problem by proposing an interface suitable for fixing on a weapon and for positioning between this weapon and an optical device, such as, for example, a viewfinder, and capable of damping the accelerations suffered by the optical device with respect to those suffered by the weapon, and this without loss of precision at close range even for an optical device whose mass is greater than the kilogram. The solution provided is an interface for machine gun or submachine gun suitable for fixing on a machine gun or submachine gun and for positioning between this weapon and an optical device, where this interface comprises a longitudinal median plane XX 'and • A first part (2, 3, 4, 30, 31, 32, 33, 34) suitable for fixing on a machine gun or submachine gun, • A second part (6, 7, 35) movable with respect to the first part, • An upper part (8, 36) comprising means (9, 10, 70, 71, 72, 73, 74, 75, 76) suitable to allow the fixation, directly or indirectly, of a telescope or a camera, and • Means (5, 50, 52, 54, 56) of damping the displacement of the second part (6, 7, 35) with respect to the first part (2, 3, 4, 30, 31, 32, 33, 34), where the means (5, 50 , 52, 54, 56) of damping comprise at least a first and a second shock absorber (50, 52, 54, 56), and the first and the second part are joined by a rail (4) arranged lengthwise On the first part (33) and by a first assembly that forms a slide (7) comprising the first part and which is capable of cooperating with said rail (4) to form a slide, where the interface is characterized by the fact that one of the first and second shock absorbers (50, 52, 54, 56) is placed on one side of the longitudinal median plane and between the first part and the second part, and the other shock absorber (50, 52, 54, 56) it is placed on the other side of the longitudinal median plane XX 'and between the first part (2, 3, 4, 30, 31, 32, 33, 34) and the second part (6, 7, 35), where the first and Second dampers (50, 52, 54, 56) are installed symmetrically and parallel, eccentrically laterally on both parts of the rail (4) and the lateral sides (16, 19, 22, 24) of the first (2, 3, 4, 30, 31, 32, 33, 34) and second (6, 7, 35) parts.

    [0018] Figure 1 shows a diagram of a side view of an interface according to an embodiment of the invention, where this interface is suitable for fixing on a weapon and for positioning between this weapon and an optical device.
    [0019] This interface 1 includes:
    • A first part 2, 3, 4, suitable for fixing on a weapon,
    • A second mobile part 6, 7 with respect to the first part,
    • Means 5 for damping the displacement of the second part with respect to the first part,
    • A third part 8 called upper part and comprising means 9, 10 suitable to allow the fixation of a telescope or a camera allowing to regulate the rise.
    [0020] The first part includes, on the one hand, means 3 for fixing the interface 1 to a weapon and, on the other hand, a longitudinally arranged rail 4, where this rail is preferably of balls. The second part includes a first assembly 7 that forms a slide and apt to cooperate with said rail 4 to form a slide.
    [0021] The interface further includes means 11, 12 for adjusting the inclination of the upper part with respect to the second part.
    [0022] Figures 2 and 3 represent a diagram of a side view and a bottom view of an interface similar to that of Figure 1. This interface includes a longitudinal median plane XX ': when the interface is fixed on a weapon , the longitudinal median plane XX 'passes through the axis of the gun barrel or, when the weapon has two guns, between the axes of the guns.

    [0027] The interface also includes means 12 for adjusting the inclination of the third plate 36 with respect to the second plate 35, in cooperation with the link 11.
    [0028] Spring damping means comprise:
    - a first lateral spring 50 arranged longitudinally between the first wing 14 of the first plate 33 and a first face 51 of the first wing 21 of the second plate 35,
    - a second lateral spring 52 arranged longitudinally between a second face 53 of said first wing of the second plate 35 and the second wing 15 of the first plate 33,
    - a third lateral spring 54 arranged longitudinally between the third wing 17 of the first plate 33 and a first face 55 of the second wing 23 of the second plate 35,
    - a fourth lateral spring 56 arranged longitudinally between a second face 57 of said first wing of the second plate 35 and the fourth wing 18 of the first plate 33,
    where the first and second springs 50, 52 are arranged coaxially on one side of the interface and the third and fourth springs 54, 56 are arranged coaxially on the other side of the interface.
    [0029] Thus, each spring is placed completely on one side or the other of the longitudinal median plane XX '. These springs can be changed depending on the weight of the optician and the ammunition used to ensure optimum damping.
    [0030] As shown in Figure 4, the means 12 for adjusting the inclination of the third plate 36 with respect to the second plate 35 comprise:
    - a first, substantially L-shaped block 40 whose longest branch is fixed to a side face 41 of the second plate 35 by means of two screws 42, 43 and so that the base of the L is perpendicular to the axis of said side face 41 ,
    - An adjusting sprocket 44 connected to a wheel 45 by an axle 58 that is held in position inside a through hole made in said block 40 and so that this axle 58 is perpendicular to said longitudinal longitudinal plane XX '. The wheel 45 includes, on its face 46 opposite to that related to the cogwheel 44, a footprint 47 whose periphery has a spiral shape 48 comprising semicircular recesses 49 regularly spaced along this spiral,
    - A second L-shaped block 13 whose longest branch is fixed to a lower face 36a of the third plate 36 by means of two screws 36b, 36c and so that the base of the L is perpendicular to said lower face 36a. In addition, the outer face of the base of the L includes a rod 36d fixed perpendicularly to this face and of diameter substantially equal, but slightly smaller, than said semicircular recesses 49, where the latter form successive notches for said rod,
    - A spring arranged between said second and third plates and held in place by a first and a second pin facing, respectively, the second and third plates.
    [0031] In addition, the third plate 36 includes oblong reamers 70, 71, 72 and 73 made in the sense of thickness and a bolt 9 which allows, for example, the fixation of a Sophie type chamber and an azimuth adjustment of this last.
    [0032] Two additional reamers 74, 75 arranged in the central part of the third plate 36 and made in the thickness direction allow, for example, the fixing of a Picatinny rail on which many different pointing devices can be installed.
    [0033] The realization of the interface for the purpose of installing a Sophie-type camera on a submachine gun 12, 7 can be the following:
    A chamber is fixed on the upper face 76 of the third plate with the aid of the bolt 9 and four other bolts intended to be inserted into the oblong recesses and then into the perforated recesses of the chamber.
    The assembly formed by the interface and the chamber is then fixed to the barrel of the submachine gun 12, 7 by means of the slide formed by the bolt 3 and a notch in the shape of a dovetail 3 integral with the barrel.
    The sprocket 44 is then rotated, if necessary, to regulate the rise depending on the expected distance of the shot. The wheel 45 associated with this cogwheel 44 is interchangeable and the shape of the footprint 47 and the positioning of the hemispherical reinforcements 49 are a function of the ammunition used. Eventually, test shots are made to regulate, in azimuth, the positioning of the camera with reference to the interface.
    During shots, in burst or not, the recoil of submachine gun 12, 7 occurs with a very strong acceleration. The interface according to the invention allows, thanks to its specific damping means, to dampen this acceleration so that the chamber only undergoes an extremely weak acceleration compatible with its operation and the maintenance of its physical integrity.
    5 Numerous modifications can be made to the examples described above without leaving the framework
    of the invention. Thus, the damping means may include, instead of the springs, pneumatic or hydraulic means or an energy absorbing means, for example, with a filter.
    In addition, in the case where shots are always made at the same distance, the second part can be merged with the third part.
