Abstract
Description
La présente invention concerne un dispositif de
réglage de convergence pour un canon ou buse de fusil de
chasse par rapport à la ligne de visée, respectivement à une parallèle à cette dernière, Ainsi, dans le cas d'un
fusil à buse unique surmonté d'une bande ventilée, l'axe
de cette dernière matérialise une parallèle à la ligne de
visée, le dispositif selon l'invention permet le réglage
de la convergence de l'axe du canon par rapport audit axe
de la bande.The present invention relates to a device for
convergence adjustment for a barrel or rifle nozzle
hunting with respect to the line of sight, respectively to a parallel to the latter, Thus, in the case of a
rifle with single nozzle surmounted by a ventilated band, the axis
of the latter materializes a parallel to the line of
aimed, the device according to the invention allows adjustment
of the convergence of the axis of the barrel relative to said axis
Of the band.
Dans le cas de fusils à canon superposés, l'axe de
l'un des canons sera parallèle à ladite ligne de visée, le
dispositif selon l'invention équipant l'autre canon (dans
la pratique généralement le canon inférieur).In the case of superimposed guns, the axis of
one of the guns will be parallel to said line of sight, the
device according to the invention fitted to the other gun (in
generally the lower barrel).
On connait de nombreux dispositifs permettant de
modifier la convergence des buses de fusils superposés.There are many devices known for
modify the convergence of the superimposed gun nozzles.
La plupart consistent en un intercalaire particulier,
disposé entre les buses, et à l'aide duquel on peut très
légèrement cintrer ces dernières (voir par exemple le
brevet belge nO 837.789). L'expérience a prouvé qu'avec
des dispositifs de ce genre, il était pratiquement impossi
ble de faire varier la convergence géométrique des deux
buses sans perturber la rectitude de la buse supérieure
et, par là, la hauteur d'impact en cible de celle-ci. Or,
il se fait que les pratiquants du tir au pigeon (Trap) par
exemple, désirent que la buse supérieure tire au point
visé quel que soit le croisement souhaité pour les gerbes
de plombs tirées successivement au moyen des buses infé
rieure et supérieure.Most consist of a special interlayer,
arranged between the nozzles, and with the help of which one can very
slightly bend these (see for example the
Belgian Patent No. 837,789). Experience has shown that with
devices like this it was practically impossible
ble to vary the geometric convergence of the two
nozzles without disturbing the straightness of the upper nozzle
and, thereby, the target impact height thereof. Gold,
it happens that practitioners of pigeon shooting (Trap) by
example, want the upper nozzle to pull to the point
aimed whatever the desired crossing for the sheaves
of pellets drawn successively by means of the lower nozzles
superior and superior.
Une autre solution déjà proposée (voir brevet belge
nO 875.228), consiste en un dispositif à tube-choke échan
geable et orientable. Des tubes-chokes sont rapportés à
la bouche de la ou des buses où ils sont chacun maintenus
en place à l'aide d'une bague filetée. Ces tubes sont
réalisés de sorte que l'axe longitudinal de leur partie
interne conique (constituant le choke proprement dit)
fasse un certain angle avec l'axe de leur surface cylindri
que extérieure prenant appui dans la ou -les buses du fusil. Dès lors, à toute rotation du tube par rapport à la buse auquel il est associé correspond une orientation de-l'axe de ladite partie conique par rapport à celui de ladite buse.Another solution already proposed (see Belgian patent
No. 875.228), consists of an exchanging tube-choke device
pleasant and adjustable. Tubes-chokes are reported to
the mouth of the nozzle (s) where they are each kept
in place using a threaded ring. These tubes are
made so that the longitudinal axis of their part
internal conical (constituting the actual choke)
make an angle with the axis of their cylindrical surface
that external taking support in or -the nozzles of the rifle. Consequently, to any rotation of the tube relative to the nozzle with which it is associated corresponds an orientation of the axis of said conical part relative to that of said nozzle.
Si un tel dispositif permet en effet d'obtenir la modification désirée de la hauteur d'impact en cible de la buse correspondante, cet avantage se paie par une altera- tion parasite du réglage en déviation de la gerbe de plomb atteignant la cible. If such a device indeed makes it possible to obtain the desired modification of the target impact height of the corresponding nozzle, this advantage is paid for by a parasitic alteration of the adjustment in deviation of the sheaf of lead reaching the target.
Le but de l'invention est donc de fournir un dispositif simple et commode de réglage de convergence, sans perturber en aucune manière les réglages en déviation. The object of the invention is therefore to provide a simple and convenient device for adjusting convergence, without in any way disturbing the deflection adjustments.
A cet effet, un dispositif selon l'invention est du type constitué par au moins un tube destiné à prolonger une buse du fusil à laquelle il est solidarisé par un dispositif de fixation permettant le réglage de l'orientation de l'axe de l'alésage dudit tube par rapport à celui de la buse associée. I1 se caractérise en ce que ledit dispositif de fixation est réalisé en sorte que l'axe de l'alésage dudit tube est toujours situé dans le plan contenant l'axe de la buse et le centre du guidon du fusil équipé. To this end, a device according to the invention is of the type constituted by at least one tube intended to extend a nozzle of the rifle to which it is secured by a fixing device allowing the adjustment of the orientation of the axis of the bore of said tube relative to that of the associated nozzle. I1 is characterized in that said fixing device is made so that the axis of the bore of said tube is always located in the plane containing the axis of the nozzle and the center of the handlebar of the rifle equipped.
L'invention sera décrite plus en détail ci-après, avec référence aux dessins schématiques et purement illustratifs annexés, dans lesquels
les figures 1 et 2 montrent, partiellement en coupe, les extrémités des deux buses d'un fusil à canons superposés dont la buse inférieure est équipée d'un dispositif selon 1t invention. Ces deux figures montrent le dispositif approximativement dans ses deux positions extrêmes, le dessin étant fortement exagéré; et
la figure 3 montre l'application de l'invention à un fusil à buse unique.The invention will be described in more detail below, with reference to the accompanying schematic and purely illustrative drawings, in which
Figures 1 and 2 show, partially in section, the ends of the two nozzles of a rifle with superimposed barrels whose lower nozzle is equipped with a device according to 1t invention. These two figures show the device approximately in its two extreme positions, the drawing being greatly exaggerated; and
FIG. 3 shows the application of the invention to a rifle with a single nozzle.
Soit donc un fusil ayant deux buses superposées I et 2. A la bouche de la buse 2 est brasée une muselière 3 dont la partie supérieure est librement traversée par la buse I. Therefore, a rifle having two superposed nozzles I and 2. At the mouth of the nozzle 2 is brazed a muzzle 3 whose upper part is freely crossed by the nozzle I.
Cette muselière 3 contient un tourillon cylindrique 4 dont l'axe est normal à celui de la buse 2. Le tourillon 4 est traversé par un passage diamétral fileté dans lequel est vissé une extrémité d'un tube-choke 5. This muzzle 3 contains a cylindrical journal 4 whose axis is normal to that of the nozzle 2. The journal 4 is crossed by a diametrical threaded passage in which is screwed one end of a tube-choke 5.
La muselière 3 est pourvue de deux vis de réglage, respectivement 6 et 7, dont les extrémités intérieures viennent engager des surfaces d'appui ou platures, respectivement 8 et 9, prévues à cet effet sur le tourillon 4. The muzzle 3 is provided with two adjustment screws, respectively 6 and 7, the inner ends of which engage bearing surfaces or plates, respectively 8 and 9, provided for this purpose on the pin 4.
Les figures montrent clairement comment, en vissant et dévissant les vis 6 et 7, on peut aisément régler la convergence. The figures clearly show how, by screwing and unscrewing the screws 6 and 7, one can easily adjust the convergence.
On notera différentes caractéristiques de ce dispositif
- l'axe du tube-choke 5 est toujours situé dans le plan contenant les axes des buses 1 et 2, ce qui exclut toute modification de la déviation lors du réglage de la convergence;
- la buse 2 est raccourcie par rapport à la buse 1 d'une longueur substantiellement égale à celle du tubechoke;
- la partie interne postérieure du tube-choke 5 a été butée, comme indiqué en 10, de sorte que l'arête postérieure interne dudit tube ne se trouve jamais sur le chemin de la charge de plombs se déplaçant vers la bouche sous l'effet de la pression des gaz de la cartouche;
- du fait que la buse 1 peut librement coulisser dans la muselière 3, on évite tout effet bilame entre les deux buses lors de l'échauffement progressif de la buse inférieure, généralement plus utilisée que l'autre;;
- le tube 5 est une pièce peu onéreuse et aisément remplaçable, par exemple en cas d'usure et/ou si llutili- sateur désirerait un choke plus ouvert ou plus fermé.We will note different characteristics of this device
- The axis of the tube-choke 5 is always located in the plane containing the axes of the nozzles 1 and 2, which excludes any modification of the deviation when adjusting the convergence;
- the nozzle 2 is shortened with respect to the nozzle 1 by a length substantially equal to that of the tubechoke;
- the rear internal part of the tube-choke 5 has been stopped, as indicated in 10, so that the internal rear edge of said tube is never on the path of the load of pellets moving towards the mouth under the effect the gas pressure of the cartridge;
- the fact that the nozzle 1 can slide freely in the muzzle 3, any bimetallic strip effect between the two nozzles is avoided during the gradual heating of the lower nozzle, generally more used than the other;
the tube 5 is an inexpensive and easily replaceable part, for example in the event of wear and / or if the user would like a more open or more closed choke.
Comme représenté -la figure 3, le dispositif selon l'invention peut également équiper un fusil à buse unique. As shown in FIG. 3, the device according to the invention can also equip a rifle with a single nozzle.
Dans ce cas, la muselière 3 est solidaire d'une bande ventilée 11 portant un guidon 12 prévu sur la buse 1. In this case, the muzzle 3 is integral with a ventilated strip 11 carrying a handlebar 12 provided on the nozzle 1.
Pour le reste, le dispositif est pareil à celui décrit avec référence aux figures 1 et 2 et fonctionne exactement de la même manière. Cette exécution à buse unique intéresse plus particulièrement- à la réglementation des canons de tir aux pigeons d'argile n'autorise qu'un seul coup par cible -(par exemple les Etats-Unis d'Amerique). For the rest, the device is similar to that described with reference to Figures 1 and 2 and operates in exactly the same way. This single nozzle execution is of particular interest - the regulation of clay pigeon guns only allows one shot per target - (for example the United States of America).
Il est évident que de nombreuses modifications peuvent être apportées à l'exemple susdécrit, sans pour autant sortir du cadre de l'invention. Ainsi, par exemple, les vis de réglage pourraient occuper d'autres positions que celles représentées ou être remplacees par des moyens équivalents. It is obvious that many modifications can be made to the example described above, without going beyond the ambit of the invention. Thus, for example, the adjusting screws could occupy other positions than those shown or be replaced by equivalent means.
