Description

La présente invention concerne un appareil de scellement d'éléments de fixation, ou appareil similaire, comprenant un canon, agencé pour recevoir un élément de fixation destiné à être entraîné en translation dans le canon sous l'action des gaz de combustion d'une charge propulsive, une culasse dans laquelle un percuteur est monté coulissant, un chargeur porte-charges propulsives, entre le canon et la culasse, pourvu d'orifices de réception des charges propulsives, et des moyens pour entraîner le chargeur en déplacement.The present invention relates to an apparatus for sealing fasteners, or the like, comprising a barrel, arranged to receive a fastener intended to be driven in translation in the barrel under the action of the combustion gases of a charge. propellant, a breech in which a striker is slidably mounted, a propellant charge magazine, between the barrel and the breech, provided with orifices for receiving propellant charges, and means for driving the magazine in motion.

Le brevet DT-AS 2 031 994 décrit un appareil de ce type, dans lequel le chargeur est un chargeur en forme de disque annulaire monté rotatif sur lui-même', dont les orifices de réception des charges propulsives sont angulairement espacés de façon régulière, et qui est pourvu de dents périphériques agencées pour coopérer avec un levier d'entraînement pouvant être actionné par un levier d'armement, afin, au cours de l'armement de l'appareil, d'entraîner le chargeur en rotation sur une distance angulaire égale à celle qui sépare deux orifices voisins et présenter ainsi une nouvelle charge en face du percuteur de la culasse.The patent DT-AS 2 031 994 describes an apparatus of this type, in which the charger is a charger in the form of an annular disc mounted to rotate on itself ' , whose orifices for receiving the propellant charges are angularly spaced regularly, and which is provided with peripheral teeth arranged to cooperate with a drive lever which can be actuated by an arming lever, in order, during the arming of the apparatus, to drive the magazine in rotation over an angular distance equal to that which separates two neighboring orifices and thus present a new charge opposite the striker of the cylinder head.

L'adoption d'un tel chargeur provient de l'exigence de disposer d'un maximum de charges propulsives dans un encombrement minimal. Les orifices de réception des charges sont donc très rapprochés les uns des autres.The adoption of such a charger stems from the requirement to have a maximum of propellant charges in a minimum footprint. The charge receiving orifices are therefore very close to one another.

Avec un tel appareil, dans lequel les charges sont donc très rapprochées les unes des autres, lors de la mise à feu d'une de ces charges, les deux charges voisines peuvent très bien être aussi mises à feu par allumage sympathique, par l'intermédiaire du chargeur lui-même, qui constitue un support de propagation de la contrainte mécanique engendrée par la mise à-feu de la charge considérée.With such an apparatus, in which the charges are therefore very close to one another, when one of these charges is ignited, the two neighboring charges may very well also be ignited by ignition sympathetic, through the charger itself, which constitutes a medium for propagation of the mechanical stress generated by the firing of the charge in question.

Et espacer les orifices de réception des charges sur le chargeur ne constituerait pas une solution satisfaisante puisqu'elle serait mise en oeuvre au détriment de la quantité de charges disponibles sur le chargeur ou de l'encombrement de ce chargeur.And spacing the charge receiving orifices on the charger would not constitute a satisfactory solution since it would be implemented to the detriment of the quantity of charges available on the charger or the size of this charger.

La présente invention vise donc à éliminer ou à diminuer fortement le risque de mise à feu par allumage sympathique des charges propulsives disposées sur le chargeur d'un appareil du type mentionné ci-dessus.The present invention therefore aims to eliminate or greatly reduce the risk of ignition by sympathetic ignition of the propellant charges placed on the charger of a device of the type mentioned above.

A cet effet, la présente invention concerne un appareil de ce type, caractérisé par le fait que le chargeur comporte des moyens agencés pour faire obstacle à la propagation de la contrainte mécanique engendrée par la mise à feu d'une charge propulsive.To this end, the present invention relates to an apparatus of this type, characterized in that the charger comprises means arranged to obstruct the propagation of the mechanical stress generated by the firing of a propellant charge.

Grâce aux obstacles de l'invention, la propagation de la contrainte est fortement inhibée, à défaut d'être complètement arrêtée; et quand celle-ci atteint l'une ou l'autre des charges voisines, son niveau est tel que le risque d'allumage sympathique est considérablement réduit, sinon nul.Thanks to the obstacles of the invention, the propagation of the stress is strongly inhibited, failing to be completely stopped; and when it reaches one or other of the neighboring charges, its level is such that the risk of sympathetic ignition is considerably reduced, if not zero.

La demanderesse n'entend pas bien entendu limiter la portée de son brevet à des chargeurs montés rotatifs sur eux-mêmes.The applicant does not intend, of course, to limit the scope of its patent to chargers rotatably mounted on themselves.

Dans une forme de réalisation préférée de l'invention, le chargeur comporte de petits orifices d'inhibition de l'allumage sympathique entre les orifices de réception des charges, au moins un entre deux orifices de réception voisins, avantageusement ménagés hors de la ligne des centres de deux orifices de réception voisins, d'un côté ou de l'autre.In a preferred embodiment of the invention, the charger has small holes for inhibiting the sympathetic ignition between the charge receiving orifices, at least one between two neighboring receiving orifices, advantageously arranged outside the line of the centers of two neighboring receiving orifices, on one side or the other.

Bien entendu, l'invention s'applique aussi bien à des appareils à tir direct qu'à des appareils à masselotte, à tir indirect. On rappellera ici que, dans les appareils de ce dernier type, un élément de fixation y est entraîné sous l'action des gaz de combustion par l'intermédiaire d'une masselotte montée coulissante dans le canon.Of course, the invention applies as well to direct fire devices as to counterweight devices, indirect fire. It will be recalled here that, in devices of the latter type, a fastening element is driven therein under the action of the combustion gases by means of a counterweight slidingly mounted in the barrel.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée du chargeur de l'appareil de l'invention, en référence aux dessins annexés, sur lesquels :

  • La figure 1 est une vue de face d'une forme de réalisation préférée du chargeur de l'appareil de l'invention, sans charges propulsives, et
  • La figure 2 est une vue en coupe selon la ligne II-II de la figure 1, le chargeur étant représenté avec seulement deux orifices de réception de charge et les deux charges correspondantes, par souci de clarté.
The invention will be better understood with the aid of the following description of a preferred embodiment of the charger of the apparatus of the invention, with reference to the appended drawings, in which:
  • FIG. 1 is a front view of a preferred embodiment of the charger of the device of the invention, without propellant charges, and
  • Figure 2 is a sectional view along line II-II of Figure 1, the charger being shown with only two charge receiving ports and the two corresponding charges, for clarity.

Le chargeur 1 des dessins est celui d'un appareil de scellement d'éléments de fixation à masselotte, ou appareil similaire. Il comprend un porte-canon, un canon, monté coulissant dans le porte-canon, une masselotte, montée coulissante dans le canon pour, sous l'action des gaz de combustion produits par la mise à feu d'une charge propulsive, entraîner en translation dans le canon un élément de fixation préalablement introduit dans le canon, avant que cet élément ne pénètre dans un matériau destiné à le recevoir, une culasse, dans laquelle un percuteur est monté coulissant, et le chargeur 1, disposé entre le canon et la culasse. Hormis le chargeur 1, les éléments ci-dessus de l'appareil de l'invention, tout comme d'ailleurs les autres, n'ont pas à être décrits plus avant ni illustrés par des dessins, car ils sont parfaitement connus de tout homme de métier.The loader 1 of the drawings is that of a device for sealing the weight fastening elements, or similar device. It includes a barrel holder, a barrel, mounted sliding in the barrel holder, a counterweight, sliding mounted in the barrel for, under the action of the combustion gases produced by the ignition of a propellant charge, translation into the barrel of a fastening element previously introduced into the barrel, before this element enters a material intended to receive it, a breech, in which a striker is slidably mounted, and the magazine 1, disposed between the barrel and the breech. Apart from the charger 1, the above elements of the apparatus of the invention, just like the others, need not be described further or illustrated by drawings, because they are perfectly known to any man. business.

Le chargeur 1 se présente sous la forme générale d'un disque annulaire, formé par exemple dans une plaque, de préférence de tôle, de relativement faible épaisseur.The charger 1 is in the general form of an annular disc, formed for example in a plate, preferably of sheet metal, of relatively small thickness.

Il est pourvu d'un orifice central 2, par lequel il est monté libre sur un moyeu solidaire d'une bascule agencée pour pivoter sur le porte-canon entre une position extérieure de chargement du chargeur et une position intérieure de fonctionnement, dans laquelle il est en contact avec la paroi antérieure de la culasse. Les moyens supports du chargeur 1 sont également connus de l'homme de métier, ne serait-ce que par le brevet DT-AS 2 031 994.It is provided with a central orifice 2, by which it is freely mounted on a hub secured to a rocker arranged to pivot on the barrel holder between an external position for loading the magazine and an internal position of operation, in which it is in contact with the anterior wall of the cylinder head. The support means of the charger 1 are also known to those skilled in the art, if only by the patent DT-AS 2,031,994.

Le chargeur 1 comporte à sa périphérie des dents 3 agencées pour coopérer avec un levier d'entraînement disposé pour être lui-même actionné par un levier d'armement au cours de l'armement de l'appareil, et faire ainsi tourner pas-à-pas, et contre l'action de moyens élastiques anti- retour, le chargeur 1 sur son moyeu pour présenter à chaque pas une nouvelle charge propulsive en face du percuteur de la culasse d'une part et de la chambre à combustion du canon d'autre part.The charger 1 has at its periphery teeth 3 arranged to cooperate with a drive lever arranged to be itself actuated by an arming lever during the arming of the device, and thus rotate step by step. -not, and against the action of elastic non-return means, the charger 1 on its hub to present at each step a new propellant charge opposite the striker of the breech on the one hand and the combustion chamber of the barrel d 'somewhere else.

Le chargeur 1 est pourvu d'orifices traversants 4 de réception de charges propulsives 5. Ce sont des orifices circulaires espacés angulairement de façon régulière;The charger 1 is provided with through orifices 4 for receiving propellant charges 5. These are circular orifices spaced angularly at regular intervals;

tous à la même distance radiale du centre du chargeur. Ils sont en nombre important, huit dans l'exemple représenté. De façon conventionnelle, on a conformé la paroi des orifices 4 pour qu'ils épousent la forme des charges 5. Ainsi, la partie postérieure 6 de la paroi des orifices est conformée pour recevoir le bourrelet 7 du culot de l'étui des charges. Cette partie postérieure 6 est prolongée, vers l'avant, par une courte jupe tubulaire 8 recevant une partie de l'étui 9 des charges.all at the same radial distance from the center of the charger. There are a large number of them, eight in the example shown. Conventionally, the wall of the orifices 4 has been shaped so that they match the shape of the charges 5. Thus, the rear part 6 of the wall of the orifices is shaped to receive the bead 7 of the base of the case for the charges. This rear part 6 is extended, towards the front, by a short tubular skirt 8 receiving part of the case 9 of the charges.

Le chargeur 1 est en outre pourvu d'autres orifices traversants d'inhibition 10.The charger 1 is also provided with other through inhibition orifices 10.

Ces orifices 10, dans l'exemple représenté, sont de petits orifices circulaires, avantageusement de diamètre plus petit que celui des orifices de réception 4, espacés angulairement de façon régulière, tous à la même distance radiale du centre du chargeur 1.These orifices 10, in the example shown, are small circular orifices, advantageously of smaller diameter than that of the receiving orifices 4, angularly spaced at regular intervals, all at the same radial distance from the center of the charger 1.

Cette distance radiale du centre du chargeur 1 est dans le cas d'espèce plus petite que celle à laquelle sont disposés les orifices de réception 4, mais elle aurait pu tout aussi bien être plus grande. Il est donc à noter que dans un cas comme dans l'autre, les orifices d'inhi- bition 10 sont ménagés hors des segments de droite joignant les centres de deux orifices de réception 4 voisins, donc d'un côté ou de l'autre. Les orifices d'inhibition 10 sont disposés sensiblement au droit des points milieux de ces segments de droite.This radial distance from the center of the charger 1 is in the present case smaller than that at which the receiving orifices 4 are arranged, but it could just as easily have been greater. It should therefore be noted that in one case as in the other, the inhibition orifices 10 are formed outside the straight segments joining the centers of two neighboring receiving orifices 4, therefore on one side or from the other. The inhibition orifices 10 are arranged substantially in line with the midpoints of these straight segments.

Les orifices 10, donc au nombre de huit dans l'exemple considéré, agissent comme des obstacles à la propagation de la contrainte mécanique engendrée par la mise à feu d'une charge propulsive considérée et ont pour effet d'inhiber ou au moins de diminuer fortement le risque de mise à feu par allumage sympathique des charges propulsives voisines de la charge considérée.The orifices 10, therefore eight in number in the example considered, act as obstacles to the propagation of the mechanical stress generated by the ignition of a propellant charge considered and have the effect of inhibiting or at least reducing strongly the risk of ignition by sympathetic ignition of the propellant charges close to the charge considered.

En d'autres termes, les orifices d'inhibition 10 doivent empêcher la contrainte mécanique engendrée au niveau d'une charge 5 de venir trop contraindre, par l'intermédiaire du chargeur lui-même, le bourrelet 7 du culot de l'étui des charges voisines.In other words, the inhibition orifices 10 must prevent the mechanical stress generated at the level of a load 5 from coming too constraining, by means of the charger itself, the bead 7 of the base of the case of the neighboring charges.

On a représenté sur les dessins un chargeur comportant entre deux orifices de réception voisins 4, un seul orifice d'inhibition circulaire. Il est clair que pour réduire le niveau de la contrainte mécanique au niveau d'un orifice de réception après sa propagation depuis un orifice de réception voisin, on pourrait prévoir des orifices d'inhibition non circulaires, par exemple en forme de fente, et en disposer plus d'un entre deux orifices de réception, par exemple deux.There is shown in the drawings a charger comprising between two neighboring receiving orifices 4, a single circular muting orifice. It is clear that in order to reduce the level of mechanical stress at a reception orifice after its propagation from a neighboring reception orifice, non-circular inhibition orifices, for example in the form of a slot, could be provided, and in have more than one between two receiving orifices, for example two.

On a décrit un chargeur monté rotatif sur un moyeu. Bien entendu, on ne sortirait pas du cadre de l'invention avec un chargeur monté rotatif à l'intérieur d'un logement.A charger has been described rotatably mounted on a hub. Of course, it would not go beyond the scope of the invention with a charger mounted to rotate inside a housing.

On n'en sortirait pas davantage en ne prévoyant pas de dents d'entraînement en rotation mais des moyens d'entraînement agissant directement sur la partie en saillie des charges jouant ainsi le rôle d'ergot d'entraînement.We would not get out of it any more by not providing rotational drive teeth but drive means acting directly on the projecting part of the loads thus playing the role of drive pin.

Enfin, on a décrit l'invention en référence à un appareil de scellement, mais il est clair qu'elle s'applique à tout autre appareil pouvant être assimilé à celui-là.Finally, the invention has been described with reference to a sealing device, but it is clear that it applies to any other device which can be assimilated to this one.
