MECANISME PNEUMATIQUE POUR ARME-JOUET LANÇANT PNEUMATIC MECHANISM FOR LAUNCHING TOY-ARM
DES BILLES DE PEINTURE OU DE PLASTIQUE DE FAIBLE POIDS,LOW WEIGHT PAINT OR PLASTIC BALLS,
ACTIONNE PAR UNE MUNITION PYROTECHNIQUE SPECIFIQUE.ACTIVATED BY SPECIFIC PYROTECHNIC AMMUNITION.
La présente invention concerne un mécanisme pour arme- jouet au fonctionnement nouveau et en particulier, un mécanisme pneumatique lançant des billes de peinture ou de plastique de faible poids, actionné par une munition pyrotechnique spécifique ou par une munition à blanc, destiné à améliorer le réalisme de tir des lanceurs du type "Paintball" ou "Airsoft".The present invention relates to a toy gun mechanism with novel operation and in particular a pneumatic mechanism launching low-weight paint or plastic balls actuated by a specific pyrotechnic ammunition or by a blank ammunition intended to improve realism. firing launchers of the "Paintball" or "Airsoft" type.
Etat de la techniqueState of the art
Les lanceurs du type "Paintball" ou "Airsoft" existent depuis longtemps. Le lancement de la bille peut s'effectuer de différentes manières, soit par piston comprimant de l'air accouplé à un engrenage électrique, soit classiquement à l'aide d'une bouteille d'air comprimé ou de CO2. Tous ces lanceurs offrent très peu de réalisme de tir. Pour l'entraînement des forces armées, il existe des munitions à projectiles marquants qui offrent plus de réalisme, parmi lesquelles celles décrites dans les demandes de brevet W09841810 et W09114148, mais leur utilisation nécessite de posséder une arme de poing pour y adapter un kit de conversion.Launchers of the "Paintball" or "Airsoft" type have been around for a long time. The launching of the ball can be carried out in different ways, either by piston compressing air coupled to an electric gear, or conventionally using a cylinder of compressed air or CO 2 . All these launchers offer very little shooting realism. For the training of the armed forces, there are ammunition projectiles striking that offer more realism, among which those described in patent applications WO9841810 and WO9114148, but their use requires to have a handgun to adapt a kit of conversion.
Certaines de ces munitions s'avèrent très onéreuses en termes d'utilisation, ce qui est préjudiciable au nombre d'entraînements et par conséquent à la qualité de 1 ' intervention .Some of these ammunition prove to be very expensive in terms of use, which is detrimental to the number of training sessions and consequently to the quality of the intervention.
But de 1 ' inventionPurpose of the invention
La présente invention a pour but de concevoir un mécanisme pneumatique pour arme-jouet lançant des billes de peinture ou de plastique de faible poids actionné par une munition pyrotechnique spécifique, accessible à un public majeur, peu coûteux dans son utilisation et en offrant unThe present invention aims to design a pneumatic mechanism for a toy gun launching low-weight paint or plastic balls actuated by a specific pyrotechnic munition, accessible to a major audience, inexpensive in its use and offering a
B1879WO fonctionnement plus réaliste par rapport aux lanceurs "Paintball" et "Airsoft".B1879WO more realistic operation compared to the launchers "Paintball" and "Airsoft".
L'invention a aussi pour but de développer un mécanisme qui rend impossible l'introduction accidentelle ou volontaire d'une munition réelle dans la chambre. Il convient également de préciser que le choix des matériaux des différentes pièces du mécanisme interdit le tir d'une munition réelle, en utilisant par exemple des matières plastiques ou alliages à base d'aluminium ou de zinc. Ainsi l'invention a pour objet un mécanisme pneumatique actionné par sa une munition pyrotechnique spécifique ou par une munition à blanc qui se distingue en ce que le recul du bloc culasse actionne un piston qui comprime de l'air situé dans une chambre de compression afin de propulser une bille de peinture ou de plastique de faible poids.The invention also aims to develop a mechanism that makes it impossible accidental or voluntary introduction of a real ammunition in the room. It should also be noted that the choice of materials of the various parts of the mechanism prohibits the firing of a real munition, for example using plastics or alloys based on aluminum or zinc. Thus, the subject of the invention is a pneumatic mechanism actuated by its specific pyrotechnic ammunition or by a blank ammunition which is distinguished in that the recoil of the breech block actuates a piston which compresses air located in a compression chamber so as to to propel a ball of paint or plastic of low weight.
Selon une variante de réalisation, le mécanisme peut être activé par une munition à blanc. Cette variante améliore considérablement la qualité de l'entraînement et, par suite, la qualité de l'intervention. Elle est donc principalement destinée à l'entraînement de l'armée et des forces de l'ordre. L'invention a également pour objet une munition pyrotechnique spécifique adaptée au mécanisme pneumatique ci- dessus. Cette munition se distingue en ce qu'elle comprend un étui pourvu de plusieurs rainures régulières sur sa partie avant, un piston introduit en force dans l'étui, et une amorce standard.According to an alternative embodiment, the mechanism can be activated by a blank ammunition. This variant considerably improves the quality of the training and, consequently, the quality of the intervention. It is therefore mainly intended for the training of the army and the police. The invention also relates to a specific pyrotechnic munition adapted to the pneumatic mechanism above. This ammunition is distinguished in that it comprises a case provided with several regular grooves on its front part, a piston introduced into force in the case, and a standard primer.

Fig. 4 représente une vue de détail en coupe de la partie arrière de la chemise et de la soupape. Fig. 5a et 5b représentent deux variantes de réalisation du bloc culasse avec le piston désolidarisé de son bloc.Fig. 4 is a detail sectional view of the rear part of the jacket and the valve. Fig. 5a and 5b show two embodiments of the breech block with the piston disengaged from its block.
Les expressions "avant" et "arrière" désignent respectivement l'avant et l'arrière des différentes pièces, dans le sens du tir. Comme le montre la figure 1, la munition comprend :The expressions "front" and "rear" respectively designate the front and the back of the various pieces, in the direction of the shot. As shown in FIG. 1, the ammunition comprises:
- un étui (2) pourvu de 2 ou 4 rainures régulières (4) sur sa partie avant. La courbure (8) ou éventuellement un chanfrein, facilite l'introduction de la munition dans la chambre (38) du corps (10) ; - un piston (3) , idéalement en caoutchouc, introduit légèrement en force dans le trou (5) de l'étui ; et- a case (2) provided with 2 or 4 regular grooves (4) on its front part. The curvature (8) or possibly a chamfer, facilitates the introduction of the ammunition in the chamber (38) of the body (10); - A piston (3), ideally made of rubber, introduced slightly in force in the hole (5) of the case; and
- une amorce standard (1) .a standard primer (1).
L'étui, de préférence en plastique, peut être obtenu par thermoformage, par moulage ou bien même être taillé dans la masse. Le piston (3) réalisé dans un matériau élastique, idéalement en caoutchouc, est obtenu par découpe de feuille de quelques millimètres d'épaisseur ou bien réalisé par moulage.The case, preferably plastic, can be obtained by thermoforming, by molding or even be cut in the mass. The piston (3) made of an elastic material, ideally rubber, is obtained by cutting the sheet a few millimeters thick or made by molding.
La figure 2 illustre le mécanisme armé de sa munition. Le corps (10) présente la particularité selon laquelle un axe (20) est disposé concentriquement dans la chambre (38) où loge la munition. De préférence, cet axe est moulé avec le corps et il est réalisé de façon à ce que sa face (32) ne gêne pas l'introduction de la munition. Lors du chargement de la munition dans la chambre, la face avant du piston (6) ne touche pas la face (32) de l'axe (20) .Figure 2 illustrates the armed mechanism of its ammunition. The body (10) has the feature that an axis (20) is concentrically disposed in the chamber (38) where the munition is housed. Preferably, this axis is molded with the body and is made so that its face (32) does not interfere with the introduction of the munition. When loading the ammunition into the chamber, the front face of the piston (6) does not touch the face (32) of the axis (20).
Lorsque le percuteur (22) frappe l'amorce (1) de la munition, il se crée une pression dans la cavité (9) de l'étuiWhen the striker (22) strikes the primer (1) of the ammunition, a pressure is created in the cavity (9) of the case
(2) poussant vers l'avant le piston (3) . La face (6) du piston vient alors en contact contre la face (32) de l'axe (20) et au fur et à mesure que la pression augmente, l'étui (2) recule en poussant le bloc culasse (21) vers l'arrière avec suffisamment(2) pushing the piston (3) forward. The face (6) of the piston then comes into contact against the face (32) of the shaft (20) and as the pressure increases, the case (2) moves back by pushing the breech block (21) backwards with enough
B1879WO de force pour actionner le système. La combinaison de l'axeB1879WO force to operate the system. The combination of the axis
(20) et de la munition pyrotechnique spécifique présente la particularité selon laquelle la munition pyrotechnique de l'invention développe suffisamment de force pour actionner le mécanisme, c'est à dire le recul complet du bloc culasse nécessaire pour le fonctionnement pneumatique et le réapprovisionnement automatique en munition du mécanisme, uniquement avec une amorce standard, sans aucune poudre additionnelle . La pression engendrée par l'amorce pousse le piston (3) de la munition jusqu'à ce que sa face arrière (7) dépasse le fond des rainures (11) de l'étui. La pression s'évacue alors à travers ces rainures et lorsque toute la pression est évacuée, le piston (3) arrête son mouvement et reste à l'intérieur du trou (5) de l'étui.(20) and the specific pyrotechnic munition has the particularity that the pyrotechnic munition of the invention develops sufficient force to actuate the mechanism, ie the complete retreat of the breech block necessary for pneumatic operation and automatic replenishment in ammunition of the mechanism, only with a standard primer, without any additional powder. The pressure generated by the primer pushes the piston (3) of the munition until its rear face (7) exceeds the bottom of the grooves (11) of the case. The pressure then escapes through these grooves and when all the pressure is removed, the piston (3) stops its movement and remains inside the hole (5) of the case.
Suivant une caractéristique de l'invention, pendant le recul du bloc culasse, le piston (24) solidaire du bloc culasse (21) recule en même temps et comprime l'air situé dans la chambre de compression (26) vers la chambre d'admission (27) .According to a characteristic of the invention, during the recoil of the breech block, the piston (24) integral with the breech block (21) moves back at the same time and compresses the air located in the compression chamber (26) towards the chamber of admission (27).
Les dimensions de la chambre de compression varient en fonction de la puissance désirée.The dimensions of the compression chamber vary according to the desired power.
Suivant une variante de réalisation du bloc culasse, ce piston peut être désolidarisé du bloc culasse. Un ressort ce compression (13) est introduit dans la chambre pour permettre au piston d'assurer sa fonction, c'est-à-dire de revenir en position initiale après avoir comprimé l'air de la chambre de compression (26) . Ce ressort est idéalement conique pour permettre au piston de faire une course suffisante nécessaire au lancement de la bille. On remarque sur la Figure 5a que, grâce à ce ressort, la face (14) du piston (24) reste en contact contre la face (15) du bloc culasse (21) .According to an alternative embodiment of the breech block, this piston can be detached from the breech block. A compression spring (13) is introduced into the chamber to allow the piston to perform its function, that is to say to return to the initial position after compressing the air of the compression chamber (26). This spring is ideally conical to allow the piston to make a sufficient race necessary to launch the ball. Note in Figure 5a that, thanks to this spring, the face (14) of the piston (24) remains in contact against the face (15) of the breech block (21).
Suivant une autre variante de réalisation représentée par la Figure 5b, une bague (16) vissée ou ajustée en force dans la chambre du corps peut assurer le maintien du piston dans cette chambre et, lors du recul du bloc de culasse, la faceAccording to another alternative embodiment shown in FIG. 5b, a ring (16) screwed or force-fitted into the chamber of the body can ensure the retention of the piston in this chamber and, during the recoil of the breech block, the face
B1879WO (15) va venir en contact contre la face (14) du piston (24), poussant ce dernier pour comprimer l'air de la chambre de compression (26) .B1879WO (15) will engage the face (14) of the piston (24), urging the piston (24) to compress the air of the compression chamber (26).
Lorsque la pression de l'air atteint un niveau suffisant pour vaincre la résistance du ressort (41), la soupape (48) translate la bille (31) vers l'avant et la dirige vers le canon. La soupape (48) est idéalement en aluminium taillé dans la masse et coulisse dans l'alésage (60) de la chemise (42) . La chemise peut être également en aluminium ou en tout autre alliage présentant les caractéristiques mécaniques voulues.When the air pressure reaches a level sufficient to overcome the resistance of the spring (41), the valve (48) translates the ball (31) forward and directs it towards the barrel. The valve (48) is ideally of aluminum cut into the mass and slides into the bore (60) of the jacket (42). The jacket may also be aluminum or any other alloy having the desired mechanical characteristics.
Comme le montre la figure 4, sur la partie arrière de la chemise (42) sont prévues 2 ou 4 rainures (33) régulières. La partie arrière de la soupape (48) dispose de trous débouchantsAs shown in Figure 4, on the rear part of the jacket (42) are provided 2 or 4 grooves (33) regular. The rear portion of the valve (48) has through holes
(34), en même nombre et orientés de préférence suivant le même axe des rainures (33) de la chemise (42) .(34), in the same number and preferably oriented along the same axis of the grooves (33) of the sleeve (42).
Ainsi lorsque la soupape se translate vers l'avant, les trous de la soupape et les rainures de la chemise vont coopérer pour former un canal et évacuer l'air comprimé afin de propulser la bille dans le canon. En fin de course, la soupape se bloque à la fin de sa translation grâce à un système de blocage.Thus, when the valve is translated forward, the holes of the valve and the grooves of the jacket will cooperate to form a channel and discharge the compressed air to propel the ball into the barrel. At the end of the race, the valve locks at the end of its translation thanks to a locking system.
Ce blocage permet d'une part, le retour du bloc culasse pour le réapprovisionnement en munition, et d'autre part, le remplissage en air de la chambre (26) . Un ressort récupérateur (non représenté) contribue au retour du bloc culasse.This blocking allows on the one hand, the return of the breech block for the replenishment of ammunition, and on the other hand, the air filling of the chamber (26). A recovery spring (not shown) contributes to the return of the breech block.
Sur les figures 2 et 3, on distingue un exemple de réalisation du système de blocage. Ce système est constitué de la languette (83) sur laquelle sont sertis deux axes (84, 85), et d'un ressort de traction ou de compression (non-représenté) qui plaque le système en direction du corps (10) . Les axes (84) et (85) coulissent dans les alésages du corps (10), respectivement (86) et (87) .In Figures 2 and 3, there is an embodiment of the locking system. This system consists of the tongue (83) on which are crimped two axes (84, 85), and a tension spring or compression (not shown) which plates the system towards the body (10). The pins (84) and (85) slide in the bores of the body (10), respectively (86) and (87).
Un trou (88) prévu sur la chemise (42) permet à l'axe (84) d'assurer le maintien de la chemise (42) dans le corps (10) et de communiquer avec le méplat (90) de la soupape (48) pour actionner le blocage.A hole (88) provided on the liner (42) allows the shaft (84) to maintain the liner (42) in the body (10) and to communicate with the flat (90) of the valve ( 48) to activate the lock.
B1879WO Lors du recul du bloc culasse (21), la partie avant (93) de l'axe (91) quitte le contact avec l'avant (94) de l'axeB1879WO When the breech block (21) is retracted, the front portion (93) of the axle (91) leaves the contact with the front (94) of the axle
(85), la face (95) de l'axe (84) s'appuie alors contre le diamètre extérieur de la soupape (48) et lors de la translation de cette dernière la face (95) frotte sur le diamètre extérieur de la soupape jusqu'à la rencontre du méplat (90) .(85), the face (95) of the axis (84) then bears against the outer diameter of the valve (48) and during the translation of the latter the face (95) rubs on the outer diameter of the valve until the flats (90) meet.
Le blocage de la soupape est ainsi établi lorsque la faceThe blockage of the valve is thus established when the face
(95) de l'axe (90) arrive en contact avec la face du méplat (90) . Lors du retour du bloc culasse, la partie avant (93) de l'axe (91) entre dans le trou (76) du corps (10) et provoque la translation de l'axe (85) . La face (95) de l'axe (84) quitte alors le méplat (90), et grâce au ressort (41) la soupape (48) revient en position initiale. Une nouvelle bille se place alors dans la chambre de lancement (44) .(95) of the axis (90) comes into contact with the face of the flat (90). When returning the breech block, the front portion (93) of the axis (91) enters the hole (76) of the body (10) and causes the translation of the axis (85). The face (95) of the axis (84) then leaves the flat (90), and thanks to the spring (41) the valve (48) returns to the initial position. A new ball is then placed in the launch chamber (44).
Les parties (94) et (93) présentent une forme appropriée de façon à ce que l'axe (91) communique la translation à l'axe (85) .The portions (94) and (93) have a suitable shape so that the axis (91) communicates the translation to the axis (85).
Lors du retour du bloc culasse (21), assuré classiquement par un ressort récupérateur (non représenté) , la partie avantWhen returning the breech block (21), provided conventionally by a recovery spring (not shown), the front part
(93) de l'axe (91) entre dans le trou (76) du corps (10) et provoque la translation de l'axe (85) . La face (95) de l'axe(93) of the axis (91) enters the hole (76) of the body (10) and causes the translation of the axis (85). The face (95) of the axis
(84) quitte alors le méplat (90) et grâce au ressort (41) la soupape (48) revient en position initiale, une nouvelle bille se place alors dans la chambre de lancement (44) .(84) then leaves the flat (90) and thanks to the spring (41) the valve (48) returns to the initial position, a new ball is then placed in the launch chamber (44).
Pendant le retour du bloc culasse, une nouvelle munition se place dans la chambre (38) .During the return of the breech block, a new ammunition is placed in the chamber (38).
Le cycle décrit dans les phases précédentes se répète jusqu'à ce qu'il n'y ait plus de munitions. Idéalement le nombre de munitions correspond au nombre de billes. Selon la puissance désirée, le mécanisme peut posséder un corps disposant de plusieurs chambres de compression (6) et par conséquent d'une culasse ayant le nombre de piston (24) correspondant . Suivant une autre variante de réalisation, le mécanisme pneumatique peut être actionné par une munition à blanc. CetteThe cycle described in the previous phases is repeated until there is no more ammunition. Ideally the number of ammunition corresponds to the number of marbles. Depending on the desired power, the mechanism may have a body having a plurality of compression chambers (6) and therefore a cylinder head having the corresponding piston number (24). According to another variant embodiment, the pneumatic mechanism can be actuated by a blank ammunition. This
B1879WO variante bien adaptée à l'entraînement de l'armée, repose sur le même principe, c'est à dire un piston solidaire ou non du bloc culasse, comprime de l'air dans une chambre de compression pour propulser une bille de peinture ou de plastique de faible poids. Le système est donc dépourvu de l'axe (20) mais dispose d'un conduit d'évacuation des gaz dégagés par la munition à blanc.B1879WO variant well suited to the training of the army, is based on the same principle, that is to say a piston integral or not the breech block, compresses air in a compression chamber to propel a ball of paint or low weight plastic. The system is therefore devoid of the axis (20) but has a conduit for evacuating gases released by the blank ammunition.
