Description

La présente invention concerne un appareil de scellement de tampon comprenant un canon dans lequel peut coulisser un piston de propulsion de tampon, un porte-canon et une poignée de tir solidaire du porte-canon, sur laquelle est montée une détente commandant la propulsion vers l'avant du piston par l'intermédiaire d'un dispositif de mise à feu.The present invention relates to a sealing device for buffer comprising a barrel in which a piston of buffer propulsion, a gun holder and a solid firing handle of the gun holder, on which is mounted a trigger controlling the forward propulsion of the piston by means of a Firing.

Généralement, le canon peut coulisser dans son porte-canon entre une position arrière de tir et une position avant de chargement. Le déplacement axial du canon dans son porte-canon est notamment destiné à replacer le piston en position arrière de tir dans le canon pour le tir suivant, le piston se trouvant, après chaque tir, à l'avant du canon après y avoir été propulsé lors du tir.Generally, the barrel can slide in its barrel holder between a rear firing position and a front loading position. The axial displacement of the barrel in its barrel holder is notably intended to replace the piston in rear shooting position in the barrel for the next shot, the piston being, after each shot, at the front of the cannon after being propelled there during the shooting.

Le canon est maintenu dans son porte-canon à l'aide d'un système de retenue pouvant s'effacer pour permettre le démontage de l'appareil.The barrel is held in its barrel holder using a retention system that can be erased to allow disassembly of the device.

Quand il s'agit de démonter l'appareil de scellement, le système de retenue s'avère difficile à manipuler.When it comes to dismantling the sealing device, the restraint system proves difficult to handle.

L'invention vise à simplifier et à faciliter la libération du canon en proposant un dispositif de retenue effaçable.The invention aims to simplify and facilitate the release of the barrel by providing an erasable retainer.

A cet effet, l'invention concerne un appareil de scellement de tampon comprenant un porte-canon, un canon et des moyens effaçables de retenue du canon dans le porte-canon permettant le coulissement du canon entre une position de chargement de charge propulsive et une position de tir, caractérisé par le fait que les moyens effaçables de retenue comprennent un bras pourvu d'un doigt de retenue monté sur le porte-canon pivotant autour d'un axe parallèle à l'axe du porte-canon, sous l'action d'une bague montée rotative sur le porte-canon autour de l'axe du porte-canon.To this end, the invention relates to a sealing device for tampon comprising a gun holder, a cannon and means erasable barrel retainer in the barrel holder allowing the barrel sliding between a load loading position propellant and a firing position, characterized in that the means erasable retainer includes an arm with a finger retainer mounted on the barrel holder pivoting about an axis parallel to the axis of the gun holder, under the action of a ring mounted rotatably on the gun holder around the axis of the gun holder.

Grâce à l'invention, il suffit de tourner la bague pour libérer le canon en translation axiale dans le porte-canon.Thanks to the invention, it suffices to turn the ring to release the barrel in axial translation in the barrel holder.

Avantageusement, le bras de retenue présente une surface de came destinée à coopérer avec la bague pour, sous l'action de la rotation de la bague, déplacer le doigt de retenue entre une position de libération du canon et une position de retenue du canon dans laquelle le doigt fait saillie à l'intérieur du porte-canon.Advantageously, the retaining arm has a surface of cam intended to cooperate with the ring for, under the action of the rotation of the ring, move the retaining finger between a position barrel release and barrel holding position in which the finger projects inside the barrel holder.

Avantageusement encore, la bague est ouverte et le bras de retenue comprend une tête de libération s'étendant dans l'ouverture de la bague.Advantageously again, the ring is open and the arm of retainer includes a release head extending through the opening of the ring.

Dans une forme de réalisation préférée de l'invention, le bras de retenue présente un ergot pour limiter le pivotement du bras agencé pour coopérer avec une surface de butée ménagée sur le porte-canon.In a preferred embodiment of the invention, the arm retainer has a lug to limit pivoting of the arm arranged to cooperate with an abutment surface formed on the barrel holder.

De préférence encore, le bras comporte un bossage d'appui en positionnement de retenue.More preferably, the arm has a support boss in restraint positioning.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation particulière de l'appareil de scellement de l'invention et d'une variante, en référence aux dessins annexés sur lesquels:

  • Figure 7 shows an axial sectional view of the sealing apparatus of Figure 6 in the barrel release position.

L'appareil de scellement de tampon représenté sur les figures 6 et 7, comprend un canon 1 dans lequel est monté coulissant un piston de propulsion de tampon, non représenté, un porte-canon 2, dans lequel le canon 1 est monté coulissant, solidaire d'une poignée 3 pourvue d'une détente de commande de tir par l'intermédiaire ici d'un dispositif de mise à feu.The tampon sealing apparatus shown in the figures 6 and 7, includes a barrel 1 in which is slidably mounted a buffer propulsion piston, not shown, a gun holder 2, in which the barrel 1 is slidably mounted, integral with a handle 3 provided with a fire control trigger via here a firing device.

L'appareil de scellement comprend en outre un dispositif effaçable de retenue du canon 1 dans le porte-canon 2 permettant, en position de retenue, le coulissement du canon entre une position avant de chargement de charge propulsive et une position arrière de tir, et en position de libération, le démontage du canon 1 de son porte-canon 2.The sealing apparatus further comprises a device erasable retaining barrel 1 in the barrel holder 2 allowing, in retaining position, the barrel sliding between a front position propellant charge loading and rear firing position, and in the release position, disassembly of the barrel 1 from its barrel holder 2.

Dans la forme de réalisation des figures 1 et 2, le système effaçable de retenue du canon 1 dans le porte-canon 2 comporte un bras effaçable de retenue 4 et une bague 6 d'actionnement du bras 4.In the embodiment of Figures 1 and 2, the system erasable retaining barrel 1 in the barrel holder 2 has a erasable retaining arm 4 and a ring 6 for actuating the arm 4.

Le bras 4 est monté sur le porte-canon 2 et s'étend dans une fenêtre 12 ménagée dans le porte-canon 2. Le bras 4 peut pivoter autour d'un axe 7 fixé sur le porte-canon 2 et parallèle à l'axe 8 du porte-canon 2, entre une position de retenue du canon 1 et une position de libération du canon 1, explicitées plus loin.The arm 4 is mounted on the barrel holder 2 and extends in a window 12 formed in the barrel holder 2. The arm 4 can pivot around an axis 7 fixed on the barrel holder 2 and parallel to the axis 8 of the barrel holder 2, between a barrel 1 retaining position and a barrel 1 release position, explained below.

On notera que le bras 4 est légèrement courbé vers l'axe 8 du porte-canon 2, la courbure du bras 4 étant sensiblement la même que celle du porte-canon 2.Note that the arm 4 is slightly curved towards the axis 8 of the gun holder 2, the curvature of the arm 4 being substantially the same as that of the gun holder 2.

La bague 6 est montée sur le porte-canon 2, rotative autour de l'axe 8 du porte-canon 2, et ménage une ouverture 11 de réception du bras 4.The ring 6 is mounted on the barrel holder 2, rotatable around of the axis 8 of the barrel holder 2, and provides an opening 11 for reception arm 4.

Le bras 4, représenté sur la figure 3, comprend un doigt de retenue 5 faisant saillie de la surface intérieure du bras 4 orientée vers l'intérieur du porte-canon 2, et une tête de libération 14, prolongeant l'extrémité libre du bras 4, et s'étendant dans l'ouverture 11 de la bague 6.The arm 4, shown in Figure 3, includes a finger retainer 5 protruding from the inner surface of the arm 4 oriented towards inside the barrel holder 2, and a release head 14, extending the free end of the arm 4, and extending into the opening 11 of the ring 6.

La surface extérieure 13 du bras 4 fait office de surface de came destinée à être poussée par un bord de verrouillage 24 de l'ouverture 11 de la bague 6, pour déplacer le doigt de retenue 5 entre sa position de libération et sa position de retenue dans laquelle il fait saillie à l'intérieur du porte-canon 2.The outer surface 13 of the arm 4 acts as a surface for cam intended to be pushed by a locking edge 24 of the opening 11 of the ring 6, to move the retaining finger 5 between his liberation position and his restraint position in which he does projection inside the barrel holder 2.

En outre, la surface extérieure 13 du bras 4 présente un bossage 17d'appui contre la surface intérieure de la bague 6, destiné à renforcer l'appui de la bague 6 contre le bras 4 en position de retenue.In addition, the outer surface 13 of the arm 4 has a boss 17 of bearing against the inner surface of the ring 6, intended to strengthen the support of the ring 6 against the arm 4 in the retaining position.

La tête de libération 14 est destinée à servir de butée à la bague 6 lorsque celle-ci est en position de verrouillage du canon 1 et à faire pivoter le bras 4 de sa position de retenue à sa position de libération sous l'action de poussée d'un bord de libération 23 de l'ouverture 11 de la bague 6, opposé au bord de verouillage 24, contre une surface ici inclinée 22 de la tête de libération 14, afin d'entraíner en pivotement de libération le bras 4. The release head 14 is intended to serve as a stop for the ring 6 when the latter is in the barrel 1 locking position and at rotate arm 4 from its retaining position to its position release under the pushing action of a release edge 23 of the opening 11 of the ring 6, opposite the locking edge 24, against a surface here inclined 22 of the release head 14, in order to drive in release pivoting arm 4.

Enfin, le bras 4 comprend un ergot 15 faisant saillie d'une surface latérale du bras 4, et le porte-canon 2 présente une surface de butée 16 destinée à bloquer en pivotement le bras 4 par l'intermédiaire de l'ergot 15, lors de la libération du canon 1.Finally, the arm 4 comprises a lug 15 projecting from a lateral surface of the arm 4, and the gun holder 2 has a surface of stop 16 intended to pivotally block the arm 4 via of lug 15, when the barrel 1 is released.

La bague 6 ménage ici deux évidements 20, 21 d'indexation, et le porte-canon 2 porte, sur sa surface extérieure, une bille 18 montée sur ressort 19 et destinée à venir se loger dans les deux évidements 20, 21 pour indexer la bague 6 en rotation, respectivement en position de verrouillage correspondant à la position de retenue du bras 4 et en position de libération.The ring 6 here has two indexing recesses 20, 21, and the barrel holder 2 carries, on its outer surface, a ball 18 mounted on spring 19 and intended to be housed in the two recesses 20, 21 for indexing the ring 6 in rotation, respectively in the position of lock corresponding to the arm 4 retaining position and release position.

Après la description structurelle de l'appareil de scellement et de son système effaçable de retenue, la libération et le verrouillage de la bague 6, pour respectivement libérer le canon 1 de son porte-canon 2, et retenir le canon 1 dans son porte-canon 2, vont maintenant être décrits.After the structural description of the sealing device and its erasable restraint, release and locking system of the ring 6, to respectively release the barrel 1 from its barrel holder 2, and retain the barrel 1 in its barrel holder 2, now go be described.

En position de verrouillage, la bague 6 recouvre le bras 4 en position de retenue, sur toute l'étendue du bras 4, à l'exception de la tête de libération 14 qui s'étend dans l'ouverture 11 de la bague 6. La tête 14 bloque ainsi la rotation de la bague 6, le bord de verrouillage étant en butée contre la tête 14. En position de retenue, le doigt 5 fait saillie dans le passage du canon 1 à l'intérieur du porte-canon 2. En outre, la bille d'indexation 18 est logée dans l'évidement de verrouillage 20.In the locked position, the ring 6 covers the arm 4 in restraint position, over the entire extent of the arm 4, except for the release head 14 which extends into the opening 11 of the ring 6. The head 14 thus blocks the rotation of ring 6, the locking edge being in abutment against the head 14. In the retaining position, the finger 5 is projection in the passage of the barrel 1 inside the barrel holder 2. In in addition, the indexing ball 18 is housed in the recess of lock 20.

Afin de libérer le canon 1, on tourne la bague 6 de façon à ce qu'elle découvre le bras 4.In order to release the barrel 1, the ring 6 is turned so that let her discover the arm 4.

En fin de rotation de libération de la bague 6, le bord de libération 23 vient pousser la tête de libération 14 en soulevant le bras 4 qui pivote à travers l'ouverture 11 de la bague 6 jusqu'à ce que l'ergot 15 vienne en butée contre la surface de butée 16 du porte-canon 2. Le bras 4 est alors en position de libération, le doigt de retenue 5 étant effacé du passage du canon 1 à l'intérieur du porte-canon 2.At the end of the release rotation of the ring 6, the edge of release 23 pushes the release head 14 by lifting the arm 4 which pivots through the opening 11 of the ring 6 until the lug 15 comes into abutment against the abutment surface 16 of the gun holder 2. The arm 4 is then in the release position, the retaining finger 5 being erased from the passage of the barrel 1 inside the barrel holder 2.

En position de libération de la bague 6 et du bras 4, la bille d'indexation 18 est logée dans l'évidement de libération 21.In the release position of the ring 6 and of the arm 4, the ball indexing 18 is housed in the release recess 21.

Pour verrouiller le canon 1 en position de retenue dans le porte-canon 2, on tourne la bague 6 en sens inverse du sens de verrouillage. Lors de la rotation, la surface intérieure 44 et le bord de verrouillage 24 de la bague 6 appuient contre la surface de came 13 puis le bossage 17 du bras 4 qui pivote vers l'axe 8 du porte-canon 2 jusqu'à ce que la tête de libération 14 vienne buter contre un bord de la fenêtre 12 du porte-canon. Le bras 4 et la bague 6 sont de nouveau alors en position de retenue et en position de verrouillage, respectivement.To lock the barrel 1 in the retaining position in the barrel holder 2, the ring 6 is turned in the opposite direction to the direction of locking. During rotation, the inner surface 44 and the edge of locking 24 of ring 6 press against cam surface 13 then the boss 17 of the arm 4 which pivots towards the axis 8 of the barrel holder 2 until the release head 14 comes up against an edge of the gun holder window 12. The arm 4 and the ring 6 are again then in the retaining position and in the locking position, respectively.

Dans la variante représentée sur les figures 4 et 5, le système d'indexation comprend, à la place de la bille 18 et des évidements 20, 21, un bossage 31 situé sur la surface intérieure de la bague 30 montée de façon élastique, et destiné à venir se loger dans un creux 32 ménagé entre le bossage d'appui 34 et la tête de libération 35 du bras de retenue 33, pour indexer en rotation la bague 30 en position de retenue.In the variant shown in Figures 4 and 5, the system indexing includes, in place of the ball 18 and the recesses 20, 21, a boss 31 located on the inner surface of the ring 30 mounted resiliently, and intended to be housed in a hollow 32 formed between the support boss 34 and the release head 35 of the arm of retainer 33, for indexing in rotation the ring 30 in position detention.
