Description

La présente invention concerne une balle d' exercice à base de matière plastique.The present invention relates to a plastic based exercise ball.

Les balles d'exercice connues sont à base de matière plastique pour être suffisamment légères afin de présenter une portée nettement plus réduite que celle des balles réelles . Les balles d'exercice connues sont soit en matière plastique soit en matière plastique surmoulée sur une bague métallique, par exemple en laiton, disposée sur la partie arrière de la balle. Cette bague en laiton joue un double rôle.The known exercise balls are plastic-based to be light enough to have a significantly reduced range than that of real balls. The known exercise balls are either plastic or plastic overmolded on a metal ring, for example brass, arranged on the rear part of the ball. This brass ring plays a double role.

Tout d'abord, cette bague forme une ceinture qui vient en prise avec les rayures du canon de l'arme, en assurant ainsi l'étanchéité de la balle par rapport à l'intérieur du canon, tout en évitant dans une large mesure un contact direct entre la matière plastique et l'intérieur de ce canon afin d'éviter l'encrassement de ce dernier par cette matière plastique.First, this ring forms a belt which engages with the scratches of the barrel of the weapon, thus ensuring the tightness of the bullet relative to the interior of the barrel, while avoiding to a large extent a direct contact between the plastic and the inside of this barrel to avoid fouling of the latter by this plastic.

Par ailleurs, cette bague en laiton a pour but de lester la balle. En effet, sans cette bague, la balle serait trop légère et instable sur sa trajectoire.Furthermore, the purpose of this brass ring is to ballast the ball. Indeed, without this ring, the ball would be too light and unstable on its trajectory.

Cette balle d'exercice connue présente de nombreux inconvénients.This known exercise ball has many disadvantages.

Son coût est relativement élevé, d'une part du fait que la bague en laiton doit être réalisée avec une grande précision, et d'autre part, parce que le surmoulage de la matière plastique autour de la bague en laiton préalablement disposée dans le moule, est une opération délicate et donc coûteuse.Its cost is relatively high, on the one hand because the brass ring must be produced with great precision, and on the other hand, because the overmolding of the plastic material around the brass ring previously placed in the mold , is a delicate operation and therefore expensive.

Par ailleurs, l'expérience montre que la liaison entre la matière plastique et la bague en laiton n'est pas toujours parfaite, de sorte que, parfois, cette bague se détache de la matière plastique, ce qui a pour effet de déstabiliser complètement la trajectoire de la balle.Furthermore, experience shows that the connection between the plastic and the brass ring is not always perfect, so that sometimes this ring comes off from the plastic, which has the effect of completely destabilizing the trajectory of the ball.

D'autre part, la concentricité de la bague par rapport au reste de la balle n'est pas non plus toujours parfaite, ce qui a pour effet d'affecter la précision du tir.On the other hand, the concentricity of the ring compared to the rest of the ball is also not always perfect, which has the effect of affecting the accuracy of the shot.

Le but de la présente invention est de remédier aux inconvénients de la réalisation précitée, en créant une balle d'exercice à base de matière plastique, peu coûteuse à fabriquer et permettant des tirs précis et parfaitement reproductibles.The object of the present invention is to remedy the drawbacks of the abovementioned embodiment, by creating an exercise ball based on plastic material, inexpensive to manufacture and allowing precise and perfectly reproducible shots.

Suivant l'invention, la balle d'exercice est caractérisée en ce qu'elle est réalisée entièrement en matière plastique chargée de particules d'un métal ou alliage ductile, uniformément réparties dans la matière plastique, la teneur de ces particules étant telle que la densité de la balle soit comprise entre 3 et 5, cette matière plastique renfermant en outre des particules d'un lubrifiant solide.According to the invention, the exercise ball is characterized in that it is made entirely of plastic loaded with particles of a metal or ductile alloy, uniformly distributed in the plastic, the content of these particles being such that the density of the ball is between 3 and 5, this plastic material also containing particles of a solid lubricant.

Le fait que la balle soit réalisée entièrement par moulage d'une matière plastique chargée, rend sa fabrication peu coûteuse et permet d'éviter les inconvénients liés à l'emploi d'une bague métallique.The fact that the bale is produced entirely by molding a charged plastic material, makes its manufacture inexpensive and makes it possible to avoid the drawbacks associated with the use of a metal ring.

Les particules d'un métal ou alliage ductile permettent de lester la matière plastique et d'obtenir la densité désirée pour la balle. Conjointement, l'expérience a montré que la présence de ces particules ainsi que la lubrification obtenue par le lubrifiant solide confèrent à la balle d'exercice d'excellentes conditions balistiques à l'intérieur du canon et empêchent l'encrassement de ce dernier, ce qui paraissait inévitable du fait de l'absence d'une ceinture métallique venant en prise directe avec les rayures du canon.The particles of a metal or ductile alloy make it possible to ballast the plastic material and to obtain the desired density for the bale. Jointly, experience has shown that the presence of these particles as well as the lubrication obtained by the solid lubricant give the exercise ball excellent ballistic conditions inside the barrel and prevent fouling of the latter, this which seemed inevitable due to the absence of a metal belt coming in direct engagement with the barrel scratches.

Selon une version préférée de l'invention, la matière plastique de la balle est en polyamide. Cette matière présente une excellente résistance mécanique et supporte très bien les températures engendrées à l'intérieur du canon, lors du tir.According to a preferred version of the invention, the plastic material of the ball is made of polyamide. This material has excellent mechanical resistance and withstands temperatures well indoors. laughing gun, when fired.

Les particules de métal ou d'alliage ductile sont de préférence en bronze, mais elles peuvent être constituées également de ouivre ou de plomb.The particles of metal or of ductile alloy are preferably made of bronze, but they can also consist of copper or lead.

Le lubrifiant solide est de préférence du bisulfure de molybdène.The solid lubricant is preferably molybdenum disulfide.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

La figure unique annexée, donnée à titre d'exemple non limitatif, est une vue en coupe longitudinale d'une balle d'exercice conforme à l'invention.The single appended figure, given by way of nonlimiting example, is a view in longitudinal section of an exercise ball according to the invention.

Sur cette figure, on voit que la balle est réalisée entièrement en matière plastique 1, chargée de particules 2 d'un métal ou alliage ductile et d'un lubrifiant solide 3, sous forme de poudre uniformément répartie à l'intérieur de cette matière plastique.In this figure, we see that the ball is made entirely of plastic 1, charged with particles 2 of a metal or ductile alloy and a solid lubricant 3, in the form of powder uniformly distributed inside this plastic material .

La matière plastique 1 est de préférence un polyamide qui présente en l'absence de charges,les propriétés suivantes permettant sa sélection :

  • - densité à 20°C: 1,04
  • - tension à la rupture: 550 bars
  • - module d'élasticité: 10.000 bars
  • - dureté Rockwel (échelle R): 106
The plastic material 1 is preferably a polyamide which, in the absence of fillers, has the following properties allowing it to be selected:
  • - density at 20 ° C: 1.04
  • - tensile strength: 550 bars
  • - modulus of elasticity: 10,000 bars
  • - Rockwel hardness (scale R): 106

Les particules 2 de métal ou d'alliage ductile sont de préférence constituées par des billes de bronze (alliage cuivre-étain) présentant un diamètre compris entre 0,04 et 0,1 mm:

  • La teneur de ces particules est telle que la densité de la balle soit comprise entre 3 et 5, ce qui correspond aux densités optimales pour une balle d'exercice. En effet, l'expérience montre que lorsque la densité est inférieure à 3, la balle présente une trajectoire instable et lorsque cette densité est supérieure à 5, la balle présente des caractéristiques et notamment une portée trop proches de celles d'une balle réelle.
The particles 2 of metal or of ductile alloy preferably consist of bronze balls (copper-tin alloy) having a diameter of between 0.04 and 0.1 mm:
  • The content of these particles is such that the density of the ball is between 3 and 5, which corresponds to the optimal densities for an exercise ball. Indeed, experience shows that when the density is less than 3, the ball has an unstable trajectory and when this density is more than 5, the ball has characteristics and in particular a range too close to that of a real bullet.

Les meilleures conditions sont réalisées lorsque la proportion de billes de bronze 2 est comprise entre 75 et 85% en poids de la balle.The best conditions are achieved when the proportion of bronze balls 2 is between 75 and 85% by weight of the ball.

Le lubrifiant solide 3 est constitué de préférence par de la poudre de bisulfure de molybdène. La proportion pondérale de cette poudre peut varier entre 0,1 et 1% en poids.The solid lubricant 3 preferably consists of molybdenum disulphide powder. The weight proportion of this powder can vary between 0.1 and 1% by weight.

On donne ci-après un exemple de composition pondérale d'une balle conforme à l'invention, ayant donné d'excellents résultats:

  • - polyamide: environ 20%
  • - billes de bronze de diamètre compris entre b,04 et 0,1 mm: 80%
  • - poudre de bisulfure de molybdène: 0,3%
An example of the weight composition of a ball according to the invention is given below, having given excellent results:
  • - polyamide: around 20%
  • - bronze balls with a diameter between b, 04 and 0.1 mm: 80%
  • - molybdenum disulphide powder: 0.3%

Cette matière présente les propriétés physiques suivantes:

  • Densité à 20°C: 4
  • Tension à la rupture: 340 bars
  • Module d'élasticité: 18.000 bars
  • Dureté Rockwel (échelle R): 106
This material has the following physical properties:
  • Density at 20 ° C: 4
  • Breaking tension: 340 bars
  • Modulus of elasticity: 18,000 bars
  • Rockwel hardness (scale R): 106

Pour fabriquer les balles conformes à l'invention, on mélange, dans un malaxeur classique, les divers constituants de la composition précitée et on moule les balles par injection du mélange obtenu dans un- moule approprié.To manufacture the balls according to the invention, the various constituents of the above-mentioned composition are mixed in a conventional mixer and the balls are molded by injection of the mixture obtained in an appropriate mold.

Cette opération est beaucoup moins coûteuse que celle réalisée pour fabriquer les balles d'exercice connues, du fait de l'absence de surmoulage d'une bague métallique usinée avec précision.This operation is much less expensive than that carried out to manufacture known exercise balls, due to the absence of overmolding of a precision machined metal ring.

Par ailleurs, les balles sont ainsi obtenues dans des conditions parfaitement reproductibles, du fait qu'elles sont réalisées dans une matière homogène et qu'elles ne comportent pas de bague métallique, de sorte que les problèmes liés aux défauts de concentricité de cette bague par rapport au reste de la balle,sont évités.Furthermore, the balls are thus obtained under perfectly reproducible conditions, because they are made of a homogeneous material and that they do not include a metal ring, so that the problems associated with defects in the concentricity of this ring with respect to the rest of the ball are avoided.

D'autre part, la présence des billes de bronze et la lubrification obtenue par le bisulfure de molybdène permettent d'obtenir, pour la balle, d'excellentes conditions balistiques à l'intérieur du canon. En particulier, la balle vient en prise avec les rayures du canon, dans des conditions de frottement optimales, sans arrachement de matière, ni encrassement de l'intérieur du canon. Cette dernière propriété est tout à fait inattendue car on pouvait craindre que le contact direct entre l'intérieur du canon et la matière plastique engendre un encrassement de ce dernier. C'est pour cette raison d'ailleurs, entre autres, que les balles d'exercice en matière plastique, connues jusqu'à présent, comportent une bague métallique destinée à venir en prise directe avec les rayures du canon.On the other hand, the presence of the bronze balls and the lubrication obtained by molybdenum disulphide make it possible to obtain, for the bullet, excellent ballistic conditions inside the barrel. In particular, the bullet comes into contact with the scratches of the barrel, under optimal friction conditions, without tearing of material, or fouling of the interior of the barrel. This latter property is quite unexpected because it was feared that direct contact between the interior of the barrel and the plastic material would cause fouling of the latter. It is for this reason, moreover, inter alia, that the plastic exercise balls, known until now, comprise a metal ring intended to come into direct contact with the scratches of the barrel.

Par ailleurs, étant donné que les balles d'exercice conformes à l'invention peuvent être fabriquées dans des conditions parfaitement reproductibles et du fait qu'elles sont réalisées en une matière homogène, ces balles présentent la précision optimale qui est recherchée dans les tirs d'exercice.Furthermore, since the exercise balls according to the invention can be manufactured under perfectly reproducible conditions and because they are made of a homogeneous material, these balls have the optimum precision which is sought in the shots of 'exercise.

Bien entendu, l'invention n'est pas limitée à l'exemple que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications, sans sortir du cadre de l'invention.Of course, the invention is not limited to the example which has just been described and many modifications can be made to it, without departing from the scope of the invention.

Ainsi, le polyamide pourrait être remplacé par toute autre matière plastique ayant des propriétés physiques analogues.Thus, the polyamide could be replaced by any other plastic material having similar physical properties.

Les particules 2 en bronze pourraient être remplacées par des grains ou des billes de cuivre, de plomb ou d'un autre métal ou alliage plus ductile que l'acier du canon de l'arme.The bronze particles 2 could be replaced by grains or balls of copper, lead or another metal or alloy more ductile than the steel of the barrel of the weapon.

Le bisulfure de molybdène pourrait être remplacé par un autre lubrifiant solide,tel que le graphite.Molybdenum disulfide could be replaced by another solid lubricant, such as graphite.

Bien entendu, la balle d'exercice conforme à l'invention peut être adaptée à tous les calibres des armes de poing ou d'épaule , ou des mitrailleuses.Of course, the exercise ball according to the invention can be adapted to all calibers of handguns or long guns, or machine guns.
