Description

La présente invention concerne le domaine du tir ou du lancer sur cible mobile, et porte sur un dispositif de présentation d'une cible de tir ou de lancer en regard d'une fenêtre.The present invention relates to the field of shooting or throwing on a mobile target, and relates to a device for presenting a shooting or throwing target next to a window.

Dans le but de rendre le tir ou le lancer sur cible plus attrayant, on a déjà proposé de remplacer les cibles fixes par des cibles mobiles, que l'on fait défiler en regard d'une fenêtre à travers laquelle un utilisateur, respectivement tireur ou lanceur, doit chercher à les atteindre; afin de permettre à l'utilisateur de développer ses réflexes, on prévoit alors souvent des moyens permettant non seulement de faire défiler les cibles, mais également de les escamoter ou de les présenter à l'utilisateur de façon brutale pendant leur défilement en regard de la fenêtre, de façon aussi inattendue que possible.In order to make shooting or throwing on target more attractive, it has already been proposed to replace fixed targets with moving targets, which are scrolled opposite a window through which a user, respectively shooter or launcher, must seek to reach them; in order to allow the user to develop his reflexes, means are often provided which not only make it possible to scroll the targets, but also to retract them or to present them to the user in a brutal manner while they are scrolling opposite the window, as unexpectedly as possible.

Il apparaît toutefois que ce caractère inattendu disparaît vite pour l'utilisateur entraîné, qui con- nait l'itinéraire de défilement des cibles et détermine aisément des positions privilégiées d'escamotage et de présentation en regard de la fenêtre.However, it appears that this unexpected feature quickly disappears for the trained user, who knows the target scrolling route and easily determines preferred retraction and presentation positions facing the window.

Le but de la présente invention est de remédier à cet inconvénient en proposant un dispositif permettant de présenter en regard de la fenêtre une ou plusieurs cibles en donnant à la présentation un caractère pseudo-aléatoire, c'est-à-dire un caractère au moins apparemment aléatoire pour l'utilisateur.The object of the present invention is to remedy this drawback by proposing a device making it possible to present one or more targets next to the window by giving the presentation a pseudo-random character, that is to say a character at least seemingly random to the user.

A cet effet, la présente invention prévoit, pour la présentation d'une cible de tir ou de lancer en aval et en regard d'une fenêtre, en référence à un sens de tir ou de lancer prédéterminé, approximativement horizontal, la cible présentant alors perpendiculairement à ce sens des dimensions inférieures aux dimensions correspondantes de la fenêtre, un dispositif comportant des moyens pour animer la cible d'un mouvement complexe combinant un mouvement de rotation autour d'un axe approximativement horizontal et un mouvement de translation suivant une direction approximativement perpendiculaire à la direction de cet axe, en aval d'un panneau opaque fixe délimitant la fenêtre, en référence au sens de tir ou de lancer, et des moyens pour donner à ce mouvement de rotation et à ce mouvement de translation un sens respectif et/ou une amplitude respective et/ou une vitesse respective tels que la cible soit présentée en regard de la fenêtre pseudo-aléatoirement dans le temps et quant à se trajectoire, entre deux passages en regard du panneau.To this end, the present invention provides, for the presentation of a shooting or throwing target downstream and opposite a window, with reference to a predetermined direction of shooting or throwing, approximately horizontal, the target then presenting perpendicular to this direction of the dimensions smaller than the corresponding dimensions of the window, a device comprising means for animating the target with a complex movement combining a rotational movement around an approximately horizontal axis and a translational movement in an approximately perpendicular direction to the direction of this axis, downstream of a fixed opaque panel delimiting the window, with reference to the direction of firing or throwing, and means for giving this rotational movement and this translational movement a respective direction and / or a respective amplitude and / or a respective speed such that the target is presented opposite the window pseudo-randomly in time and as for its trajecto ire, between two passages opposite the panel.

Cette combinaison d'un mouvement de rotation et d'un mouvement de translation permet, notamment si un opérateur fait varier ces sens, amplitudes, vitesses indépendamment les uns des autres et à volonté, ou si l'on utilise à cet effet en asservissement à un ordinateur convenablement programmé, par exemple pour donner un caractère réellement aléatoire à ces variations, de présenter la cible en regard de la fenêtre en lui faisant accomplir par rapport à cette dernière les trajectoires les plus inattendues pour l'utilisateur qui, en particulier, lorsque la cible se trouve en regard du panneau, c'est-à-dire en dehors de la fenêtre, ignore où la cible réapparaîtra en regard de cette dernière, quelle trajectoire elle suivra alors, quelle sera sa vitesse et comment cette dernière évoluera; en particulier, le tireur se trouve ainsi placé dans des conditions proches de celles du tir sur pigeon d'argile, particulièrement attrayant, sans subir les contraintes d'espace et de coût indisso- ciablement liées à ce type de tir.This combination of a rotational movement and a translational movement allows, in particular if an operator varies these directions, amplitudes, speeds independently of each other and at will, or if one uses for this purpose in enslavement to a computer suitably programmed, for example to give a truly random character to these variations, to present the target opposite the window by making it accomplish in relation to the latter the most unexpected trajectories for the user who, in particular, when the target is next to the panel, that is to say outside the window, ignores where the target will reappear next to the latter, what trajectory it will then follow, what its speed will be and how it will evolve; in particular, the shooter is thus placed in conditions close to those of clay pigeon shooting, which is particularly attractive, without being subject to the constraints of space and cost inextricably linked to this type of shooting.

Selon un mode de mise en oeuvre encore plus attrayant de la présente invention, des moyens sont prévus pour animer ainsi plusieurs cibles d'un mouvement complexe combinant un mouvement respectif de rotation autour d'un axe respectif approximativement horizontal et un mouvement respectif de translation suivant une direction respective approximativement perpendiculaire à la direction de cet axe, en aval du panneau en référence au sens de tir ou de lancer, ainsi que des moyens pour donner à tous ces mouvements un sens respectif, une amplitude respective et une vitesse respective, avantageusement variables, tels que deux de ces cibles ou plus se croisent en regard de la fenêtre pseudo-aléatoirement dans le temps et quant à leur trajectoire, entre deux passages en regard du panneau.According to an even more attractive embodiment of the present invention, means are provided for thus animating several targets with a complex movement combining a respective movement of rotation around a respective approximately horizontal axis and a respective movement of translation along a respective direction approximately perpendicular to the direction of this axis, downstream of the panel with reference to the direction of shooting or throwing, as well as means for giving all these movements a respective direction, a respective amplitude and a respective speed, advantageously variable , such that two or more of these targets cross in front of the window pseudo-randomly in time and as for their trajectory, between two passages opposite the panel.

La règle de tir ou de lancer peut alors être d'atteindre simultanément deux cibles en cours de croisement, ce qui nécessite de l'utilisateur une anticipation sur les mouvements respectifs des deux cibles, et constitue un excellent exercice de réflexes.The shooting or throwing rule can then be to hit two targets simultaneously while crossing, which requires the user to anticipate the respective movements of the two targets, and constitutes an excellent exercise in reflexes.

Dans ce cas également, il est avantageux qu'un opérateur, ou encore un ordinateur convenablement programmé, fasse varier les sens, amplitudes, vitesses de rotation et de translation indépendamment les uns des autres.In this case also, it is advantageous for an operator, or even a suitably programmed computer, to vary the directions, amplitudes, rotation and translation speeds independently of each other.

D'autres caractéristiques et avantages du dispositif selon l'invention ressortiront de la description ci-dessous, relative à deux exemples non limitatifs de réalisation de ce dispositif appliqué au tir sur cible par arme à feu, ainsi que des dessins annexés qui font partie intégrante de cette description.Other characteristics and advantages of the device according to the invention will emerge from the description below, relating to two nonlimiting examples of embodiment of this device applied to target shooting by firearm, as well as the attached drawings which form an integral part of this description.

On se référera en premier lieu aux fig. 1 et 2, où l'on a désigné par 1 un bâti support rigide immobilisé par rapport au sol 2 soit de fait de son poids propre, soit par tout autre moyen approprié non représenté; les notions d'orientation et de position relative des différents éléments qui seront décrits par la suite devront être considérées en référence à la position d'utilisation du dispositif telle qu'elle est définie par cette immobilisation du bâti support 1 par rapport au sol 2, et telle qu'elle est illustrée.We will first refer to Figs. 1 and 2, where 1 is designated by a rigid support frame immobilized relative to the ground 2 either because of its own weight, or by any other suitable means not shown; the concepts of orientation and relative position of the various elements which will be described later should be considered with reference to the position of use of the device as defined by this immobilization of the support frame 1 relative to the ground 2, and as shown.

Le bâti support 1 porte de façon solidaire un panneau frontal opaque, rigide 3 présentant dans l'exemple illustré une orientation moyenne approximativement verticale et perpendiculaire au sens prédéterminé de tir 1 lui-même approximativement horizontal, et ce panneau 3 est percé d'une fenêtre 4 dont il définit une périphérie extérieure 6 qui, selon le mode de mise en oeuvre préféré illustré, présente une forme cylindrique de révolution autour d'un axe 5 sensiblement parallèle au sens I, c'est-à-dire approximativement horizontal, et fixe par rapport au bâti support 1; tout autour de la périphérie extérieure 6 de la fenêtre 4, le panneau frontal opaque 3 est muni de déflecteurs anti-ricochet tels que 7 propres à recevoir l'impact de projectiles tirés approximativement suivant le sens I mais en dehors de la fenêtre 4, pour les dévier vers des moyens d'arrêt tels que 8 en absorbant un maximum de leur énergie; cette conception est connue en elle-même, et ne sera de ce fait pas détaillée davantage.The support frame 1 integrally carries an opaque, rigid front panel 3 having in the example illustrated an average orientation approximately vertical and perpendicular to the predetermined direction of fire 1 itself approximately horizontal, and this panel 3 is pierced with a window 4 of which it defines an outer periphery 6 which, according to the preferred embodiment illustrated, has a cylindrical shape of revolution about an axis 5 substantially parallel to the direction I, that is to say approximately horizontal, and fixed relative to the support frame 1; all around the outer periphery 6 of window 4, the opaque front panel 3 is provided with anti-ricochet deflectors such as 7 adapted to receive the impact of projectiles fired approximately in direction I but outside window 4, to divert them to stop means such as 8 by absorbing a maximum of their energy; this design is known in itself, and will therefore not be detailed further.

Conformément à la présente invention, il est prévu des moyens 9 de présentation d'au moins une cible, et plus précisément de deux cibles 10 et 11 dans cet exemple, en aval et en regard de la fenêtre 4 en référence au sens de tir et ces moyens de présentation 9, portés par le bâti support 1, sont propres à donner au tireur l'illusion d'une présentation aléatoire, dans le temps et quant à leur trajectoire, des deux cibles 10 et 11 en regard de la fenêtre 4 entre deux passages de ces cibles en regard du panneau 3, qui les dissimule alors à la vue; on remarquera que le dispositif peut également être prévu pour présenter ainsi une seule cible, ou plus de deux cibles.In accordance with the present invention, means 9 are provided for presenting at least one target, and more precisely two targets 10 and 11 in this example, downstream and facing window 4 with reference to the direction of fire and these presentation means 9, carried by the support frame 1, are capable of giving the shooter the illusion of a random presentation, over time and as to their trajectory, of the two targets 10 and 11 facing the window 4 between two passages of these targets opposite panel 3, which then conceals them from view; it will be noted that the device can also be provided to thus present a single target, or more than two targets.

A cet effet, dans l'exemple illustré, le bâti support 1 porte de façon solidaire, en aval de la fenêtre 4 si l'on se réfère au sens I, des paliers 210 aptes à recevoir et guider un arbre 211 à la rotation autour de l'axe 5 par rapport au bâti support 1.To this end, in the example illustrated, the support frame 1 carries integrally, downstream of the window 4 if we refer to direction I, bearings 210 capable of receiving and guiding a shaft 211 for rotation around of axis 5 with respect to the support frame 1.

L'arbre 211 porte de façon solidaire une roue dentée 282 reliée par une chaîne 14 à un pignon de chaîne 15 porté de façon solidaire par un arbre de sortie, d'axe 16, parallèle à l'axe 5 et comme lui fixe par rapport au bâti support 1, d'un variateur de vitesse 13 lui-même monté sur un arbre de sortie d'un moteur électrique 12, si bien que, lorsque le moteur 12 est en service et en agissant sur le réglage du variateur de vitesse 13, on peut provoquer l'entraînement de l'arbre 211 à la rotation autour de l'axe 5 par rapport au bâti support 1 dans un sens ou dans l'autre, éventuellement alternativement dans un sens et dans l'autre, avec une vitesse et/ou le cas échéant une amplitude que l'on peut avantageusement faire varier à volonté pendant la rotation soit par télécommande manuelle du variateur de vitesse 13, soit par asservissement de ce dernier à un programme prédéterminé par exemple restitué par un ordinateur; la réalisation de moyens 17 susceptibles d'être utilisés à cet effet est du domaine des aptitudes normales d'un homme du métier et ces moyens ne seront pas décrits.The shaft 211 carries integrally a toothed wheel 282 connected by a chain 14 to a chain pinion 15 carried integrally by an output shaft, of axis 16, parallel to the axis 5 and as it fixes relative to the support frame 1, a speed variator 13 itself mounted on an output shaft of an electric motor 12, so that, when the motor 12 is in service and by acting on the adjustment of the speed variator 13 , the shaft 211 can be caused to rotate about the axis 5 relative to the support frame 1 in one direction or the other, optionally alternately in one direction and in the other, with a speed and / or where appropriate an amplitude which can advantageously be varied at will during rotation either by manual remote control of the speed controller 13, or by slaving the latter to a predetermined program for example restored by a computer; the production of means 17 capable of being used for this purpose is within the scope of the normal skills of a person skilled in the art and these means will not be described.

Outre la roue dentée 82, l'arbre 211 porte de façon solidaire, entre les paliers 210 et le panneau frontal 3, un châssis rigide 18 présentant deux plans de symétrie propres 19, 20 se coupant à angle droit suivant l'axe 5 notamment dans un souci d'équilibrage à la rotation autour de ce dernier vis-à-vis du bâti support 1.In addition to the toothed wheel 82, the shaft 211 carries integrally, between the bearings 210 and the front panel 3, a rigid frame 18 having two own planes of symmetry 19, 20 intersecting at right angles along the axis 5 in particular in a concern for balancing the rotation around the latter with respect to the support frame 1.

Plus précisément, dans l'exemple de réalisation illustré, le châssis 18 comporte deux bras rigides 21, 22, disposés parallèlement entre eux, symétriquement l'un de l'autre par rapport au plan 19, selon un même plan moyen perpendiculaire à l'axe 5 à proximité duquel ils sont reliés de façon solidaire à l'arbre 211 par un ensemble du moyeu rigide 27; chacun des bras 21 et 22 porte de façon solidaire, en extrémité, à une distance de l'axe 5 supérieur au rayon R de la fenêtre 4, deux potences rigides, respectivement 23, 24 en ce qui concerne le bras 21 et 25, 26 en ce qui concerne le bras 22; ces potences 23 à 26 forment par rapport au bras 21, 22 correspondant une saillie vers le panneau 3, parallèlement à l'axe 5, pour porter de façon solidaire, entre les bras 21 et 22 et le panneau 3, deux poutres rigides 28, 29 rectilignes, parallèles entre elles, symétriques l'une de l'autre par rapport au plan 20, et situées selon un même plan moyen 30 perpendiculaire à l'axe 5, entre les bras 21 et 22 d'une part et le panneau frontal 3 d'autre part; chacune des poutres 28 et 29 est en outre symétrique par rapport au plan 19 auquel elle est perpendiculaire; on remarquera que la distance d séparant du plan 20 chacune des poutres 28 et 29 est supérieure au rayon R de la fenêtre 4, si bien qu'en aucune façon, lors de la rotation du châssis 18 autour de l'axe 5 par rapport au bâti support 1, une zone des poutres 28 et 29 ne peut se trouver en regard de la fenêtre 4 suivant le sens I; on remarquera en outre que la conception du bâti support 1 dans sa zone 31 placée radialement (en référence à l'axe 5) en regard du châssis 18 laisse subsister vis-à-vis de ce dernier un jeu 32 suffisant pour autoriser un mouvement de rotation du châssis 18 autour de l'axe 5 vis-à-vis du bâti support 1 au moins en va-et-vient sur une course de moins de 180° comme c'est le cas dans l'exemple illustré, ou bien en va-et-vient sur une course d'au moins 180° ou encore sur une rotation en continu dans un sens constant, dans le cas de variantes non illustrées.More specifically, in the illustrated embodiment, the chassis 18 comprises two rigid arms 21, 22, arranged parallel to each other, symmetrically to one another with respect to the plane 19, according to the same mean plane perpendicular to the axis 5 near which they are integrally connected to the shaft 211 by an assembly of the rigid hub 27; each of the arms 21 and 22 bears integrally, at the end, at a distance from the axis 5 greater than the radius R of the window 4, two rigid brackets, respectively 23, 24 as regards the arm 21 and 25, 26 with regard to the arm 22; these brackets 23 to 26 form with respect to the arm 21, 22 corresponding a projection towards the panel 3, parallel to the axis 5, to carry in a solid manner, between the arms 21 and 22 and the panel 3, two rigid beams 28, 29 rectilinear, parallel to each other, symmetrical to each other with respect to the plane 20, and situated along the same mean plane 30 perpendicular to the axis 5, between the arms 21 and 22 on the one hand and the front panel 3 on the other hand; each of the beams 28 and 29 is furthermore symmetrical with respect to the plane 19 to which it is perpendicular; it will be noted that the distance d separating from the plane 20 each of the beams 28 and 29 is greater than the radius R of the window 4, so that in no way, during the rotation of the chassis 18 around the axis 5 relative to the support frame 1, an area of beams 28 and 29 cannot be located opposite window 4 in direction I; it will also be noted that the design of the support frame 1 in its zone 31 placed radially (with reference to the axis 5) opposite the chassis 18 allows there to remain with respect to the latter a clearance 32 sufficient to allow movement of rotation of the chassis 18 around the axis 5 with respect to the support frame 1 at least back and forth over a stroke of less than 180 ° as is the case in the example illustrated, or else back and forth on a stroke of at least 180 ° or on a continuous rotation in a constant direction, in the case of variants not illustrated.

Le châssis 1.8 qui vient d'être décrit a pour fonction d'assurer la liaison, avec l'arbre 211 et le bâti support 1 par l'intermédiaire de ce dernier, de moyens porte-cible tels que 33 en ce qui concerne la cible 10. et 34 en ce qui concerne la cible 11, montés sur ce châssis 18 de façon à pouvoir se déplacer en translation par rapport à ce dernier.The chassis 1.8 which has just been described has the function of ensuring the connection, with the shaft 211 and the support frame 1 by means of the latter, of target-carrying means such as 33 as regards the target 10. and 34 as regards the target 11, mounted on this chassis 18 so as to be able to move in translation relative to the latter.

A cet effet, chacune des poutres 28 et 29 porte en extrémité deux paliers, respectivement 35, 36 et 37, 8 se correspondant deux à deux par symétrie par rapport au plan 19 en ce qui concerne les deux paliers d'une même poutre 28, 29, et par symétrie par rapport au plan 20 en ce qui concerne chacun des paliers d'une poutre 28, 29 par rapport à l'un des paliers de l'autre de ces poutres.To this end, each of the beams 28 and 29 carries at the end two bearings, respectively 35, 36 and 37, 8 corresponding two by two by symmetry with respect to the plane 19 as regards the two bearings of the same beam 28, 29, and by symmetry with respect to the plane 20 as regards each of the bearings of a beam 28, 29 with respect to one of the bearings of the other of these beams.

Ainsi, le palier 35 de la poutre 28 et le palier 37 de la poutre 29 se correspondent par symétrie par rapport au plan 20, pour recevoir un arbre rectiligne 39 d'axe 40, immobiliser cet axe 40 par rapport au châssis 18 selon une orientation perpendiculaire au plan 20, et guider l'arbre 39 à la rotation sur lui-même autour de cet axe 40 par rapport au châssis 18; de même les paliers 36 et 38 se correspondant par symétrie par rapport au plan 20 reçoivent un arbre rectiligne 41 d'axe 42, en immobilisant cet axe 42 par rapport au châssis 18 dans une position symétrique de celle de l'axe 40 par rapport au plan 19 et en guidant l'arbre 41 à la rotation autour de cet axe 42 par rapport au châssis 18.Thus, the bearing 35 of the beam 28 and the bearing 37 of the beam 29 correspond by symmetry by relative to the plane 20, to receive a rectilinear shaft 39 with an axis 40, immobilize this axis 40 relative to the chassis 18 in an orientation perpendicular to the plane 20, and guide the shaft 39 to rotate about itself around this axis 40 relative to the chassis 18; similarly the bearings 36 and 38 corresponding by symmetry with respect to the plane 20 receive a rectilinear shaft 41 of axis 42, by immobilizing this axis 42 relative to the chassis 18 in a position symmetrical to that of the axis 40 relative to the plane 19 and by guiding the shaft 41 to rotation about this axis 42 relative to the chassis 18.

L'arbre 41 se prolonge au-delà du palier 36 et de la poutre 28 dans une zone où il porte de façon solidaire un pignon de chaîne 45 qu'une chaîne d'entraînement 46 relie à un pignon de chaîne 47 porté de façon solidaire par un arbre de sortie d'un variateur de vitesse 48 monté de façon solidaire sur la poutre 28 et présentant lui-même une entrée raccordée à un arbre de sortie d'un moteur électrique 49 également porté de façon solidaire par la poutre 28; l'ensemble moteur 49-variateur de vitesse 48 est télécommandé quant à l'alimentation du moteur 49 en électricité, quant au réglage du variateur 48 pour régler alors la vitesse de rotation du pignon 47 autour de son axe 51 fixe par rapport à la poutre 28 et parallèle à l'axe 42, quant au sens de cette rotation qui peut être toujours le même ou alterné, et quant à l'amplitude de cette rotation lorsqu'elles s'effectue alternativement dans un sens et dans l'autre, par des moyens 50 en tout point comparable aux moyens 17 mais agissant de telle sorte que ces réglages de l'ensemble 48-49 soient indépendants de ceux de l'ensemble 12-13.The shaft 41 extends beyond the bearing 36 and the beam 28 in an area where it carries integrally a chain sprocket 45 which a drive chain 46 connects to a chain sprocket 47 carried integrally by an output shaft of a speed variator 48 mounted integrally on the beam 28 and itself having an input connected to an output shaft of an electric motor 49 also carried integrally by the beam 28; the motor 49-speed variator 48 assembly is remotely controlled as regards the supply of electricity to the motor 49, as for the adjustment of the variator 48 to then adjust the speed of rotation of the pinion 47 about its axis 51 fixed relative to the beam 28 and parallel to the axis 42, as to the direction of this rotation which may always be the same or alternated, and as to the amplitude of this rotation when they are performed alternately in one direction and in the other, by means 50 at any point comparable to means 17 but acting so that these settings of the assembly 48-49 are independent of those of the assembly 12-13.

En outre, entre les paliers 36 et 38, à proximité respectivement de l'un et l'autre, l'arbre 41 porte de façon solidaire deux roues de chaîne identiques 43 et 44, symétriquement de chacune desquelles par rapport au plan 19 l'arbre 39 porte de façon solidaire une roue de chaîne respective 52, 53, identique aux roues 43 et 44.In addition, between the bearings 36 and 38, in the vicinity respectively of one and the other, the shaft 41 carries integrally two identical chain wheels 43 and 44, symmetrically of each of which with respect to the plane 19 ' shaft 39 integrally carries a respective chain wheel 52, 53, identical to the wheels 43 and 44.

Sur les deux roues dentées 43 et 52 se correspondant par symétrie par rapport au plan 19 est tendue, le cas échéant à l'aide de moyens connus non représentés, une chaîne 54 continue et, de façon analogue, sur les pignons 44 et 53 est tendue de la même façon une chaîne 55 qui correspond à la chaîne 54 par symétrie par raport au plan 20, et ces deux chaînes 54 et 55 sont reliées entre elles, dans des zones localisées se correspondant par symétrie par rapport au plan 20, par les moyens porte-cible 33, lesquels peuvent présenter différentes formes et par exemple, comme il est illustré, la forme de deux liens souples tels que des câbles 33a et 33b dont chacun est tendu entre ces deux chaînes pour présenter une forme rectiligne et une orientation perpendiculaire au plan 20; ces deux liens 33a et 33b sont distants mutuellement d'une écartement e inférieur au diamètre D de la cible 10 supposée circulaire, de telle sorte que cette dernière puisse être fixée sur eux par tout moyen approprié et par exemple par agrafage élastique dans une position dans laquelle elle présente un plan moyen perpendiculaire au plan 20 et dans laquelle, par exemple et comme il est illustré, elle est elle-même symétrique par rapport à ce dernier; on remarquera que le diamètre D de la cible 10 est largement inférieur au diamètre 2R de la fenêtre 4, et que l'écartement entre les axes 40 et 42 est lui-même supérieur à 2R; ainsi, la rotation du pignon 47 sous l'action de l'ensemble 48-49 dans un sens donné amène la cible 10, entraînée par les chaînes 54 et 55 auxquelles elle est raccordée par les liens 33a et 33b, à longer le panneau 3, en aval de celui-ci si l'on réfère au sens 1, selon un mouvement de translation de direction moyenne 82 fixe par rapport au châssis 18, incluse dans le plan 20 et perpendiculaire au plan 19, c'est-à-dire perpendiculaire à l'axe 5, amenant cette cible alternativement en regard du panneau 3, qui la dissimule alors à la vue du tireur, ou en regard de la fenêtre 4 entre deux passages en regard du panneau 3; lors de ce mouvement, les zones respectives de la chaîne 54 et de la chaîne 55 qui portent les liens 33a et 33b sont situées du même côté du plan moyen 30 que le panneau 3 et le plan moyen de la cible est approximativement perpendiculaire au sens I; si le sens de rotation du pignon 47 est constant, ce passage le long du panneau 3 s'effectue toujours dans le même sens fixe par rapport au châssis 18, et intervient en alternance avec un déplacement en translation de l'autre côté du plan 30, moyennant contournement de l'axe 40 et de l'axe 42; si, par contre, le sens de rotation du pignon 47 est alternativement l'un ou l'autre, avec éventuellement un temps d'arrêt du moteur 49 au changement de sens, il peut ne pas y avoir contournement des axes 40 et 42 et trajet de l'autre côté du plan moyen 30; dans ce cas, l'inversion de sens de rotation du pignon 47, qui se traduit par une inversion de sens de translation de la cible 10 le long du panneau 3, peut éventuellement intervenir alors que la cible 10 se trouve en regard de la fenêtre 4, ou encore exclusivement lorsque la cible 10 est dissimulée par le panneau 3.On the two toothed wheels 43 and 52 corresponding by symmetry with respect to the plane 19 is tensioned, if necessary using known means not shown, a chain 54 continues and, similarly, on the pinions 44 and 53 is in the same way stretched a chain 55 which corresponds to the chain 54 by symmetry with respect to the plane 20, and these two chains 54 and 55 are connected together, in localized zones corresponding by symmetry with respect to the plane 20, by the target holder means 33, which can have different shapes and for example, as illustrated, the shape of two flexible links such as cables 33a and 33b each of which is stretched between these two chains to present a rectilinear shape and a perpendicular orientation on plane 20; these two links 33a and 33b are mutually distant by a spacing e less than the diameter D of the target 10 supposed to be circular, so that the latter can be fixed on them by any suitable means and for example by elastic stapling in a position in which it has a mean plane perpendicular to the plane 20 and in which, for example and as illustrated, it is itself symmetrical with respect to the latter; it will be noted that the diameter D of the target 10 is much less than the diameter 2R of the window 4, and that the spacing between the axes 40 and 42 is itself greater than 2R; thus, the rotation of the pinion 47 under the action of the assembly 48-49 in a given direction causes the target 10, driven by the chains 54 and 55 to which it is connected by the links 33a and 33b, to follow the panel 3 , downstream of this if we refer to direction 1, in a translational movement of medium direction 82 fixed relative to the frame 18, included in the plane 20 and perpendicular to the plane 19, that is to say perpendicular to the axis 5, bringing this target alternately opposite the panel 3, which then conceals it from the view of the shooter, or opposite the window 4 between two passages facing the panel 3; during this movement, the respective zones of the chain 54 and of the chain 55 which carry the links 33a and 33b are situated on the same side of the mean plane 30 as the panel 3 and the mean plane of the target is approximately perpendicular to the direction I ; if the direction of rotation of the pinion 47 is constant, this passage along the panel 3 is always carried out in the same fixed direction relative to the chassis 18, and occurs alternately with a translational movement on the other side of the plane 30 , bypassing the axis 40 and the axis 42; if, on the other hand, the direction of rotation of the pinion 47 is alternately one or the other, with possibly a stop time of the motor 49 at the change of direction, there may not be bypassing of the axes 40 and 42 and path on the other side of the mean plane 30; in this case, the reversal of the direction of rotation of the pinion 47, which results in an inversion of the direction of translation of the target 10 along the panel 3, may possibly occur while the target 10 is located opposite the window 4, or even exclusively when the target 10 is hidden by the panel 3.

Pour porter et déplacer l'autre cible 11 de l'exemple de réalisation illustré, il est prévu sur l'arbre 41, entre les roues de chaîne 43 et 44, un arbre creux 56, coaxial, monté à la rotation autour de l'axe 42, par rapport au châssis 18, indépendamment de l'arbre 41 sur lequel il est à cet effet monté à rotation libré; de même, un arbre creux 57 disposé coaxialement autour de l'arbre 39, entre les roues de chaîne 52 et 53, est monté à la rotation sur ce dernier autour de l'axe 40, ce qui assure son montage à la rotation autour de cet axe par rapport au châssis 18 indépendamment de la rotation de l'arbre 39.To carry and move the other target 11 of the illustrated embodiment, there is provided on the shaft 41, between the chain wheels 43 and 44, a hollow shaft 56, coaxial, mounted for rotation around the axis 42, with respect to the chassis 18, independently of the shaft 41 on which it is for this purpose mounted in free rotation; similarly, a hollow shaft 57 arranged coaxially around the shaft 39, between the chain wheels 52 and 53, is mounted for rotation on the latter around the axis 40, which ensures its mounting for rotation around this axis relative to the chassis 18 independently of the rotation of the shaft 39.

Respectivement à proximité de la roue de chaîne 43 et de la roue de chaîne 44, l'arbre 56 porte de façon solidaire deux roues de chaîne identiques 58, 59 dont le diamètre est plus faible que celui des roues 43 et 44; de même, respectivement à proximité de la roue de chaîne 52 et à proximité de la roue de chaîne 53, l'arbre 57 porte de façon solidaire deux roues de chaîne 60 et 61 identiques, dont le diamètre, identique à celui des roues 58 et 59, est inférieur à celui des roues 52 et 53.Respectively close to the chain wheel 43 and the chain wheel 44, the shaft 56 integrally carries two identical chain wheels 58, 59 whose diameter is smaller than that of the wheels 43 and 44; similarly, respectively near the chain wheel 52 and near the chain wheel 53, the shaft 57 integrally carries two identical chain wheels 60 and 61, the diameter of which is identical to that of wheels 58 and 59, is lower than that of wheels 52 and 53.

Les roues 58 et 60 d'une part, 59 et 61 d'autre part, assurent le guidage de deux chaînes continues, respectivement 62 et 63, tendues éventuellement par des moyens connus de l'homme du métier, et qui occupent des positions symétriques l'une de l'autre par rapport au plan 20; dans des zones respectives également symétriques l'une de l'autre par rapport à ce plan 20, elles portent de façon solidaire les moyens porte-cible 34 en tout point semblable aux moyens 33 et qui portent la cible 11 comme ces derniers portent la cible 10, c'est-à-dire de telle sorte que cette cible 11, identique à la cible 10, soit symétrique par rapport au plan 20 et présente un plan moyen approximativement perpendiculaire au sens 1 lorsque les zones des chaînes 62 et 63 qui portent cette cible 11 sont situées du même côté du plan moyen 30 que le panneau 3 et que la cible 11 se trouve en regard de la fenêtre 4 suivant le sens I.The wheels 58 and 60 on the one hand, 59 and 61 on the other hand, guide two continuous chains, respectively 62 and 63, possibly stretched by means known to those skilled in the art, and which occupy symmetrical positions from each other with respect to plane 20; in respective zones which are also symmetrical to one another with respect to this plane 20, they support the target-carrying means 34 in all points similar to the means 33 and which carry the target 11 as the latter carry the target 10, that is to say so that this target 11, identical to the target 10, is symmetrical with respect to the plane 20 and has a mean plane approximately perpendicular to the direction 1 when the zones of the chains 62 and 63 which carry this target 11 are located on the same side of the mean plane 30 as the panel 3 and that the target 11 is located opposite the window 4 in the direction I.

Entre la roue de chaîne 61 et la roue de chaîne 53 de l'arbre 39, l'arbre 57 porte de façon solidaire un pignon de chaîne 64 qu'une chaîne 65 relie à un pignon de sortie 66, d'axe 69 parallèle à l'axe 64, d'un variateur de vitesse 67 accouplé à un moteur électrique 68, ce variateur 67 et ce moteur 68 étant portés de façon solidaire par la poutre 29 dans une position approximativement symétrique de celle de l'ensemble 48-49 par rapport à l'axe 5 pour des raisons d'équilibre.Between the chain wheel 61 and the chain wheel 53 of the shaft 39, the shaft 57 integrally carries a chain sprocket 64 which a chain 65 connects to an output sprocket 66, of axis 69 parallel to the axis 64, of a variable speed drive 67 coupled to an electric motor 68, this variator 67 and this motor 68 being carried integrally by the beam 29 in a position approximately symmetrical to that of the assembly 48-49 by compared to axis 5 for reasons of balance.

L'ensemble 67-68 est télécommandé, comme l'ensemble 48-49 et l'ensemble 12-13, par des moyens 70 en tout point semblable aux moyens 50 et 17, et autorisant indépendamment de ces derniers un arrêt ou une mise en route du pignon 66, à une vitesse réglable avantageusement en continu et dans un sens pouvant être constant ou alterné à volonté, avec dans ce dernier cas une amplitude également réglable à volonté.The assembly 67-68 is remotely controlled, like the assembly 48-49 and the assembly 12-13, by means 70 at all points similar to the means 50 and 17, and authorizing independently of the latter a stop or a setting route of the pinion 66, at a speed advantageously continuously adjustable and in a direction which can be constant or alternated at will, with in the latter case an amplitude also adjustable at will.

On conçoit aisément qu'en combinant à volonté, grâce aux moyens 17, 50, 70 le commencement ou l'arrêt respectif, le sens respectif, alterné à volonté, l'amplitude respective, variable à volonté, et la vitesse respective, également variable à volonté, du mouvement de rotation du châssis 18 par rapport au bâti support 1 autour de l'axe 5, du mouvement de translation de la cible 10 perpendiculairement à l'axe 5 le long du panneau 3 et en regard de la fenêtre 4, et du mouvement en tout point analogue de la cible 11, s'effectuant sur une trajectoire parallèle à celle de la cible 11 notamment le long du panneau 3 et en regard de la fenêtre 4, on puisse présenter aussi bien la cible 10 que la cible 11 en regard de cette fenêtre 4 d'une façon qui paraît aléatoire, dans le temps et quant à la trajectoire suivie par la cible en regard de la fenêtre, pour le tireur.It is easy to see that by combining at will, by means 17, 50, 70, the respective beginning or stop, the respective direction, alternating at will, the respective amplitude, variable at will, and the respective speed, also variable. at will, the rotation movement of the chassis 18 relative to the support frame 1 around the axis 5, the translational movement of the target 10 perpendicular to the axis 5 along the panel 3 and facing the window 4, and of the movement at any similar point of the target 11, taking place on a trajectory parallel to that of the target 11 in particular along the panel 3 and opposite the window 4, it is possible to present both the target 10 and the target 11 facing this window 4 in a manner which seems random, over time and as to the trajectory followed by the target opposite the window, for the shooter.

Lorsque, comme c'est le cas dans l'exemple illustré, au moins deux cibles sont prévues avec des déplacements indépendants, la règle du jeu peut consister à atteindre simultanément les deux cibles lorsqu'elles se superposent par exemple en se croisant entre le plan moyen 30 et le panneau 3, en regard de la fenêtre 4; il est alors avantageux, pour l'intérêt du jeu, de prévoir des inversions de sens de translation de l'une des deux cibles ou des deux cibles lorsqu'elles se trouvent en regard de la fenêtre 4, ou des variations brutales de leur vitesse de translation.When, as in the example illustrated, at least two targets are provided with independent displacements, the rule of the game may consist in simultaneously reaching the two targets when they overlap, for example by crossing between the plane means 30 and panel 3, opposite window 4; it is then advantageous, for the benefit of the game, to provide reversals of the direction of translation of one of the two targets or of the two targets when they are opposite window 4, or sudden variations in their speed of translation.

On remarquera également que l'on pourrait prévoir, sans sortir pour autant du cadre de la présente invention, d'autres façons de combiner en un mouvement complexe d'une cible, un mouvement de rotation autour d'un axe approximativement parallèle au sens de tir, ici l'axe 5, et un mouvement de translation suivant une direction approximativement perpendiculaire à ce sens, en aval du panneau opaque 3 délimitant la fenêtre 4, si l'on se réfère au sens de tir I; lorsque plusieurs cibles sont prévues, on peut prévoir des axes différents pour la composante de rotation de leur mouvement complexe, et/ou des directions différentes pour la composante de translation de ce mouvement complexe; quelle que soit la solution choisie, on peut en outre prévoir, sans sortir pour autant du cadre de la présente invention, de remplacer la combinaison de mouvements décrite, à savoir le déplacement des moyens porte-cibles tels que 33 et 34 à la translation par rapport au châssis 18 assurant leur liaison avec le bâti support 1 et le mouvement de rotation de ce châssis 18 par rapport à ce bâti support 1 par un mouvement de translation, par rapport à un bâti support 1 et suivant une direction approximativement perpendiculaire au sens de tir, d'un châssis comparable au châssis 18 si ce n'est qu'il porte des moyens porte-cibles appropriés à la rotation relative autour d'un axe approximativement parallèle au sens de tir; des combinaisons plus complexes de mouvement peuvent en outre être prévues et par exemple, à titre de variante du mode de mise en oeuvre de l'invention qui a été décrit et représenté, on peut prévoir de monter les cibles 10 et 11 non pas de façon fixe par rapport aux chaines qui les portent, mais de façon mobile par rapport à ces dernières soit à la translation, par exemple en va-et-vient parallèlement au plan 19, soit à la rotation autour d'un axe situé approximativement parallèlement au sens de tir 1 lorsque la cible longe le panneau 3 et la fenêtre 4, dans l'un et l'autre cas sous l'action de moyens réglables à volonté indépendamment des moyens 17, 50, 70 prévus pour le réglage des autres moyens.It will also be noted that one could provide, without departing from the scope of the present invention, other ways of combining in a complex movement of a target, a movement of rotation about an axis approximately parallel to the direction of firing, here axis 5, and a translational movement in a direction approximately perpendicular to this direction, downstream of the opaque panel 3 delimiting the window 4, if one refers to the firing direction I; when several targets are provided, it is possible to provide different axes for the component of rotation of their complex movement, and / or different directions for the component of translation of this complex movement; whatever the solution chosen, it can also be provided, without departing from the scope of the present invention, to replace the combination of movements described, namely the displacement of the target-carrying means such as 33 and 34 in translation by relative to the frame 18 ensuring their connection with the support frame 1 and the rotational movement of this frame 18 relative to this support frame 1 by a translational movement, relative to a support frame 1 and in a direction approximately perpendicular to the direction of firing, from a chassis comparable to chassis 18 except that it carries target-carrying means suitable for relative rotation about an axis approximately parallel to the firing direction; more complex combinations of movement can also be provided and for example, as a variant of the embodiment of the invention which has been described and shown, provision may be made for mounting the targets 10 and 11 not so fixed relative to the chains carrying them, but movably relative to the latter either in translation, for example back and forth parallel to plane 19, or in rotation about an axis located approximately parallel to the direction firing 1 when the target runs along the panel 3 and the window 4, in both cases under the action of means that can be adjusted as desired independently of the means 17, 50, 70 provided for adjusting the other means.

On peut en outre prévoir une variante plus élaborée du dispositif, permettant de combiner aux mouvements précités de la cible ou de chacune des cibles, à savoir la rotation autour d'un axe approximativement horizontal et la translation suivant une direction approximativement perpendiculaire à la direction de cet axe, un mouvement de rotation autour d'un axe approximativement vertical avec un sens et/ou une amplitude et/ou une vitesse que l'on fat varier, automatiquement ou par action manuelle, de façon à contribuer à présenter la cible ou les cibles en regard de la fenêtre de façon pseudo-aléatoire dans le temps et quant à la trajectoire décrite, entre deux passages de cette cible ou de ces cibles en regard du panneau.It is also possible to provide a more elaborate variant of the device, making it possible to combine with the aforementioned movements of the target or of each of the targets, namely rotation about an approximately horizontal axis and translation in a direction approximately perpendicular to the direction of this axis, a rotational movement around an approximately vertical axis with a direction and / or an amplitude and / or a speed which one can vary, automatically or by manual action, so as to contribute to present the target or the targets next to the window in a pseudo-random manner over time and as for the trajectory described, between two passages of this target or of these targets facing the panel.

On a illustré en trait mixte, aux fig. 1 et 2, une telle variante ne différant du mode de réalisation décrit précédemment que par les points suivants.Illustrated in phantom, in Figs. 1 and 2, such a variant differing from the embodiment described above only in the following points.

Au lieu d'être intégralement fixe par rapport au sol 2, le bâti support 1 est remplacé par deux parties de bâti-support dissociées 1a et 1b dont la première 1a, située en amont de la seconde 1 b en référence au sens de tir I, est fixe par rapport au sol 2 et porte de façon solidaire le panneau frontal, rigide 3 orienté comme indiqué précédemment, et dont la deuxième 1 est quant à elle mobile par rapport au sol 2 et par rapport à la première 1a, à la rotation autour d'un axe approximativement vertical 112, et porte de façon solidaire les paliers 210 de l'arbre 211 ainsi que le moteur électrique 12 d'entraînement de cet arbre 211 à la rotation et, par l'intermédiaire de l'arbre 211, l'ensemble du châssis 18 et des moyens portés par celui-ci, comme on l'a dit précédemment du bâti-support 1; avantageusement, le plan 30 inclut l'axe 112 en outre sécant de l'axe 5; les deux parties de bâti-support 1a et 1b sont séparées par un jeu 1c autorisant une telle rotation relative.Instead of being completely fixed relative to the ground 2, the support frame 1 is replaced by two parts of dissociated support frame 1a and 1b, the first of which 1a, located upstream of the second 1b with reference to the direction of fire I , is fixed relative to the ground 2 and carries in a solid manner the rigid front panel 3 oriented as indicated above, and the second 1 of which is movable relative to the ground 2 and relative to the first 1a, to rotation around an approximately vertical axis 112, and carries in a solid manner the bearings 210 of the shaft 211 as well as the electric motor 12 for driving this shaft 211 in rotation and, by means of the shaft 211, the whole of the chassis 18 and of the means carried by the latter, as said previously of the support frame 1; advantageously, the plane 30 includes the axis 112 further intersecting the axis 5; the two parts of support frame 1a and 1b are separated by a clearance 1c allowing such relative rotation.

Par exemple, à cet effet, la partie de bâti support 1a présente, de façon solidaire, une semelle approximativement horizontale 101 d'ancrage au sol, définissant d'une part un appui vers le bas pour la partie de bâti support 1 b et d'autre part un palier de guidage à la rotation, autour de l'axe 112, pour un tourillon 115 que cette partie 1 porte de façon solidaire, en saillie vers le bas; ce tourillon 115 porte lui-même de façon solidaire une roue dentée 114 reliée par une chaîne 120 à un pignon de chaîne 119 porté de façon solidaire par un arbre de sortie 117, d'axe 118 parallèle à l'axe 112, d'un groupe moteur-variateur de vitesse 116 porté de façon solidaire par la semelle 101; des moyens 122, en tout point comparables aux moyens 17, 50, 70, et indépendants de ceux-ci, permettent d'animer la partie 1 b, c'est-à-dire l'axe 5 et avec lui les moyens 9, d'un mouvement de pivotement alternatif autour de l'axe 112 avec une vitesse et/ ou une amplitude que l'on peut avantageusement faire varier à volonté pendant la rotation soit par télécommande manuelle du groupe 116, soit par asservissement de ce dernier à un programme par exemple restitué par un ordinateur.For example, for this purpose, the support frame part 1a has, in an integral manner, an approximately horizontal sole 101 for anchoring to the ground, defining on the one hand a downward support for the support frame part 1b and d on the other hand a bearing for guiding the rotation, about the axis 112, for a pin 115 which this part 1 carries integrally, projecting downwards; this pin 115 itself carries in a solid manner a toothed wheel 114 connected by a chain 120 to a chain sprocket 119 carried in a solid manner by an output shaft 117, of axis 118 parallel to axis 112, of a motor-speed variator group 116 carried integrally by the sole 101; means 122, entirely comparable to means 17, 50, 70, and independent of these, make it possible to animate part 1 b, that is to say axis 5 and with it means 9, an alternating pivoting movement around the axis 112 with a speed and / or an amplitude which can advantageously be varied at will during the rotation either by manual remote control of the group 116, or by slaving of the latter to a program for example restored by a computer.

Ainsi, en jouant de façon indépendante, grâce aux moyens de télécommande 122,17, 50, 70, sur les sens, vitesses, et éventuellement amplitudes respectifs de la rotation de la partie de bâti support 1b autour de l'axe 112 par rapport à la semelle 101, de la rotation du châssis 18 autour de l'axe 5 par rapport à la partie 1 b de bâti-support, et de translation des cibles 10 et 11 suivant la direction 82 par rapport au châssis 18, on peut déplacer les cibles 10 et 11, en regard de la fenêtre 4 d'une façon aléatoire au paraissant telle au tireur, avec l'attrait supplémentaire, par rapport au mode de mise en oeuvre décrit initialement en référence aux fig. 1 à 3, de la possibilité de reproduire un mouvement fuyant ou un mouvement approchant par une orientation de la partie 1 b telle que l'axe 5 ne soit pas parallèle au sens de tir ou de lancer I. Dans une version simplifiée de cette variante, on pourrait prévoir une rotation conjointe des parties 1 b et 1 autour de l'axe 112 par rapport à la semelle 101.Thus, by playing independently, using the remote control means 122, 17, 50, 70, on the directions, speeds, and possibly the respective amplitudes of the rotation of the support frame part 1b around the axis 112 with respect to the sole 101, of the rotation of the chassis 18 around the axis 5 relative to the part 1b of support frame, and of translation of the targets 10 and 11 in the direction 82 relative to the chassis 18, the targets 10 and 11, opposite window 4 in a random manner when appearing such as the shooter, with the additional attraction, compared to the mode of implementation described initially with reference to FIGS. 1 to 3, the possibility of reproducing a fleeing movement or an approaching movement by an orientation of the part 1 b such that the axis 5 is not parallel to the direction of shooting or throwing I. In a simplified version of this variant , a joint rotation of the parts 1b and 1 could be provided around the axis 112 with respect to the sole 101.

En outre, on prévoit avantageusement diverses dispositions propres à assurer la sécurité du dispositif.In addition, various arrangements are advantageously provided for ensuring the safety of the device.

Dans l'exemple de mise en oeuvre illustré, on a prévu à cet effet une plaque de blindage 71 plane, portée de façon solidaire par le châssis 18, perpendiculairement à l'axe 5, au moins en regard de la fenêtre 4 si l'on se réfère au sens de tir I.In the exemplary implementation illustrated, a planar shielding plate 71 is provided for this purpose, carried integrally by the chassis 18, perpendicular to the axis 5, at least opposite the window 4 if the we refer to the shooting direction I.

Afin de dissimuler au tireur les cibles 10 et 11 lorsqu'elles se déplacent éventuellement de l'autre côté du plan moyen 30 par rapport au panneau frontal 3, cette plaque de blindage 71 est disposée à l'intérieur des chaînes 62 et 63 si bien que les trajectoires respectives de ces chaînes, des chaînes 54 et 55, des moyens porte-cibles 33 et 34, et des cibles 10, 11 la contournent.In order to conceal from the shooter the targets 10 and 11 when they possibly move on the other side of the mean plane 30 relative to the front panel 3, this armor plate 71 is disposed inside the chains 62 and 63 so well that the respective trajectories of these chains, chains 54 and 55, target-carrying means 33 and 34, and targets 10, 11 bypass it.

Vers la fenêtre 4, c'est-à-dire vers l'amont si l'on se réfère au sens I, la plaque 71 porte de façon solidaire des moyens anti-ricochet également situés à l'intérieur de ces trajectoires.Towards window 4, that is to say upstream if one refers to direction I, the plate 71 carries in an integral manner anti-ricochet means also situated inside these trajectories.

Comme il apparaît plus nettement sur la fig. 3, ces moyens anti-ricochet 72 comportent une pluralité de déflecteurs juxtaposés tels que 73, 74, 75, convexes vers la fenêtre 4 et définissant entre eux, deux à deux, des fentes telles que 76 et 77 si bien qu'un projectile venant frapper l'un de ces déflecteurs, et par exemple le déflecteur 75, approximativement suivant le sens I est dévié par ce déflecteur 75 vers la fente immédiatement voisine 77, obliquement par rapport à la plaque de blindage 71 que le projectile atteint ainsi obliquement et non à angle droit, et en ayant perdu une part de son énergie; cet itinéraire d'un projectile a été schématisé par des flèches 78 à la fig. 3.As appears more clearly in FIG. 3, these anti-ricochet means 72 comprise a plurality of juxtaposed deflectors such as 73, 74, 75, convex towards the window 4 and defining between them, in pairs, slots such as 76 and 77 so that a projectile coming from strike one of these deflectors, and for example the deflector 75, approximately in the direction I is deflected by this deflector 75 towards the immediately adjacent slot 77, obliquely to the armor plate 71 which the projectile thus reaches obliquely and not at right angles, and having lost part of its energy; this route of a projectile has been shown diagrammatically by arrows 78 in FIG. 3.

A cet effet, avantageusement, chaque déflecteur 73, 74, 75 présente la forme d'une cornière définie par deux parois, telles que respectivement 74a et 74b en ce qui concerne le déflecteur 74, lesquelles parois présentent des faces principales planes, orientées à 45° environ par rapport à la plaque 71, et convergent mutuellement dans le sens d'un éloignement par rapport à cette dernière pour se raccorder mutuellement à 90° le long d'une arête commune telle que 74c qui, avantageusement, est renforcée par une cornière d'angle droit telle que 74d, vers la fenêtre 4.To this end, advantageously, each deflector 73, 74, 75 has the form of an angle defined by two walls, such as respectively 74a and 74b with regard to the deflector 74, which walls have main planar faces, oriented at 45 ° approximately with respect to the plate 71, and converge mutually in the direction of a distance from the latter so as to connect to each other at 90 ° along a common edge such as 74c which, advantageously, is reinforced by an angle right angle such as 74d, towards window 4.

On remarquera qu'ainsi, chacun des déflecteurs tels que 73, 74, 75 est concave vers la plaque blindée 71, ce qui lui permet de jouer avec cette dernière un rôle de piège des projectiles ayant ainsi pénétré entre eux; ces projectiles perdent rapidement leur énergie par ricochets successifs, puis tombent par gravité.It will be noted that thus, each of the deflectors such as 73, 74, 75 is concave towards the armored plate 71, which allows it to play with the latter a role of trapping of the projectiles having thus penetrated between them; these projectiles quickly lose their energy by successive ricochets, then fall by gravity.

Les fentes telles que 76 et 77, définies par des bords rectilignes, tels que 74e et 74f, des plaques telles que 74a et 74d définissant chaque déflecteur tel que 74, ces bords étant parallèles à l'arête telle que 74c de jonction entre ces plaques, présentent de préférence des dimensions aussi faibles que possible, juste propres à permettre le passage des projectiles dévies.The slots such as 76 and 77, defined by rectilinear edges, such as 74e and 74f, plates such as 74a and 74d defining each deflector such as 74, these edges being parallel to the edge such as 74c of junction between these plates , preferably have dimensions as small as possible, just suitable for allowing the passage of deflected projectiles.

Ces dimensions sont néanmoins suffisantes pour autoriser un passage direct, vers la plaque 71, de projectiles parvenant dans le sens de tir I juste en regard de l'une des fentes telles que 76 et 77, comme on l'a schématisé par une flèche 79.These dimensions are nevertheless sufficient to allow direct passage, towards the plate 71, of projectiles arriving in the firing direction I just opposite one of the slots such as 76 and 77, as shown by an arrow 79.

Pour éviter que de tels projectiles heurtent la plaque 71 à 90°, avec un risque de ricochet et de retour en sens inverse du sens I, on a prévu entre chacune des fentes telles que 76 et 77 et la plaque 71, sur celle-ci, un déflecteur secondaire respectif, tel que 80 ou 81, porté de façon solidaire par la plaque 71 comme les déflecteurs tels que 73, 74, 75 et présentant vers la fente correspondante une convexité propre à dévier tout projectile heurtant ce déflecteur secondaire, de telle sorte qu'il vienne au contact de la plaque 71 sous un angle inférieur à 90° et par exemple de l'ordre de 45°.To prevent such projectiles from hitting the plate 71 at 90 °, with a risk of ricochet and return in the opposite direction to the direction I, there are provided between each of the slots such as 76 and 77 and the plate 71 thereon. , a respective secondary deflector, such as 80 or 81, carried integrally by the plate 71 like the deflectors such as 73, 74, 75 and having towards the corresponding slot a convexity suitable for deflecting any projectile striking this secondary deflector, such so that it comes into contact with the plate 71 at an angle less than 90 ° and for example of the order of 45 °.

A cet effet, dans l'exemple illustré, chacun des déflecteurs secondaires tels que 80, 81 se présente sous la forme d'une cornière présentant deux parois orientées à 45° par rapport à la plaque 71 et se coupant à angle droit le long d'une arête, respectivement 80a ou 81 a, placée en regard de la fente associée telle que 76 ou 77, à une distance de cette fente suffisante pour autoriser un passage des projectiles arrivant soit directement dans le sens de tir I, soit après avoir été dévisé par l'un des déflecteurs tels que 73, 74, 75.To this end, in the example illustrated, each of the secondary deflectors such as 80, 81 is in the form of an angle iron having two walls oriented at 45 ° relative to the plate 71 and intersecting at right angles along d '' an edge, respectively 80a or 81a, placed opposite the associated slot such as 76 or 77, at a distance from this slot sufficient to allow passage of the projectiles arriving either directly in the firing direction I, or after having been unscrewed by one of the deflectors such as 73, 74, 75.

Naturellement, d'autres dispositions pourraient être choisies à cet effet sans que l'on sorte pour autant du cadre de la présente invention; on notera cependant que cette disposition est particulièrement peu encombrante, tout en offrant toute sécurité.Naturally, other arrangements could be chosen for this purpose without departing from the scope of the present invention; it will be noted however that this arrangement is particularly space-saving, while offering all security.

On comprendra aisément qu'un dispositif conforme à la présente invention peut être utilisé aussi bien pour le tir à l'arme à feu, de poing ou d'épaule, que pour le tir à l'arc ou à l'arbalète, ou pour le lancer des flèchettes ou du couteau, ou encore pour le tir à la fronde, etc.; éventuellement, en fonction du type de sport pratiqué, ce dispositif pourra connaître des adaptations mais on ne sortira pas pour autant du cadre de la présente invention.It will be readily understood that a device in accordance with the present invention can be used both for shooting with a firearm, a fist or a shoulder, as well as for archery or a crossbow, or for throwing darts or a knife, or shooting with a slingshot, etc .; possibly, depending on the type of sport practiced, this device may be subject to adaptations, but this will not go beyond the scope of the present invention.
