Abstract

The purpose of the invention is to give an aiming point which is dependent on the distance of the target (auxiliary measurement) and on its speed of displacement (a measurement which is the purpose of the invention). A device 1 for fixing on the eyepiece of a sight telescope, for example, is provided with very thin folding branches 2 which are folded by a fork 3 operated by a variable reduction and constant speed (and therefore preset) device, 4 and 5. An azimuth graduation 6 makes it possible to start and stop the folding of 2 as a function of the time taken by the target to move between the two chosen graduations of 6.

Description

L'invention a pour but la réalisation d'un dispositif simplifié de correction de visée en fonction de la vitesse de l'objectif à atteindre.The object of the invention is to produce a simplified device for aiming correction as a function of the speed of the objective to be reached.

Cette correction est courament faite, sur pièces sur affûts, par une mesure soit par gyromètre, soit par dérivation du signal de position de l'azimut , liée par calculateur à une mesure "télémétrique, dans la pratique du tir "anti-but mobile".This correction is commonly made, on parts on mountings, by a measurement either by gyrometer, or by derivation of the position signal of the azimuth, linked by computer to a measurement "rangefinder, in the practice of shooting" anti-mobile goal " .

L'objectif de l'invention est de munir de cette correction, éventuellement, des armes portées (fusils, fusils-mitrailleurs,...), d'etre de très grande simplicité et fiabilité, afin d'etre d'un emploi très large.The objective of the invention is to provide with this correction, possibly, carried weapons (rifles, machine-guns, ...), to be very simple and reliable, in order to be of very use large.

La Figure 1 représente de façon schématique un dispositif conforme à l'invention, disposé, par exemple derrière l'occulaire d'une lunette de visée.Figure 1 schematically shows a device according to the invention, arranged, for example behind the eyepiece of a telescopic sight.

La Figure 2 montre la triangulation :tireur - cible distance - vitesse de cible et vitesse du projectile tiré.Figure 2 shows the triangulation: shooter - target distance - target speed and speed of the projectile fired.

Le problème à résoudre est en effet un simple problème de géométrie, lié à des vecteurs de vitesse, et à une mesure de distance, ce qu'éxécute le dispositif montré Figure 1.The problem to be solved is in fact a simple geometry problem, linked to velocity vectors, and to a distance measurement, which the device shown in Figure 1 performs.

1 est un cercle-support du dispositif et servant de fixation sur l'occulaire d'une lunette de tir, par exemple.1 is a support circle for the device and serving for attachment to the eyepiece of a rifle scope, for example.

2 sont deux tiges très fines liées élastiquement à leur point de jonction et présentant un angle déterminé en fonction des dimensions du dispositif.2 are two very fine rods linked elastically to their junction point and having an angle determined according to the dimensions of the device.

3 est un dispositif mécanique, par exemple en fourchette, permettant quand il descend de fermer les branches formées par l'ensemble élastique 2.3 is a mechanical device, for example in a fork, allowing when it descends to close the branches formed by the elastic assembly 2.

4 est un dispositif mécanique transmettant le mouvement à 3, muni d'un dispositif de changement de vitesse par pignon, tel que connu pour certain petit moteur de modèle réduit.4 is a mechanical device transmitting the movement to 3, provided with a gear change device by pinion, as known for certain small motor of reduced model.

5 est un dispositif moteur consistant, par exemple en un dispositif mécanique d'horlogerie, donnant une vitesse constante.5 is a motor device consisting, for example of a mechanical clockwork device, giving a constant speed.

Naturellement, 4 et 5 peuvent être remplacé par un dispositif électronique, électro-mécanique, permettant des vitesses constantes et réglables.Naturally, 4 and 5 can be replaced by an electronic, electro-mechanical device, allowing constant and adjustable speeds.

6 est un repère en "millièmes" qui peut être remplacé par les extrémités des branches de 2.6 is a mark in "thousandths" which can be replaced by the ends of the branches of 2.

Le fonctionnement est très simple. L'objectif 8 de la Figure 2, vu par le tireur 7, est mis en ligne avec une des graduation de 6, selon le sens de son mouvement. On maintient la ligne de visée fixe après avoir déclenché le mouvement d'horlogerie 5 de de la Fig.l (et réglé le rapport de vitesse du trasmetteur 4, selon la vitesse du projectile à tirer). Quand l'objectif atteint l'autre radua- tion de 6, on arrête le mouvement d'horlogerie et l'angle fait par les branches de 2 représente, en fonction de la distance, l'écart de visée à apporter : on fait coincider par visée la graduation de la hausse (site,non représenté Fig.l) avec la partie de la branche de 2 qui lui est perpendiculaire (branche selon le sens de déplacement de l'objectif).The operation is very simple. The objective 8 of Figure 2, seen by the shooter 7, is put in line with one of the graduations of 6, according to the direction of its movement. The line of sight is maintained fixed after having triggered the clockwork movement 5 of FIG. 1 (and adjusted the speed ratio of the transmitter 4, depending on the speed of the projectile to be fired). When the objective reaches the other radiation of 6, we stop the clockwork movement and the angle made by the branches of 2 represents, as a function of the distance, the aiming deviation to be made: we make coincide by aiming the graduation of the rise (site, not shown in Fig.l) with the part of the branch of 2 which is perpendicular to it (branch according to the direction of movement of the objective).

Comme cité plus haut, la variation de la vitesse constante de pincement de 2 est prévue pour tenir compte de la vitesse- de projectiles différents représentée Fig.2 par le vecteur 7-9, en fonction du vecteur 8-9 qui représente la vitesse linéaire du projectile.As mentioned above, the variation of the constant pinch speed of 2 is provided to take into account the speed of different projectiles represented in Fig. 2 by the vector 7-9, as a function of the vector 8-9 which represents the linear speed of the projectile.

L'invention est destinée à l'équipement de toutes armes devant tirer à vue sur un objectif mobile se déplaçant linéairement en azimuth par rapport à la position de tir. The invention is intended for equipping all weapons intended to fire at sight on a mobile objective moving linearly in azimuth relative to the firing position.
