Definitions
- 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.
- 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.
- 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.
- the 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
- 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.
- 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.
- 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. 1 represents a sectional view of the munition.
- Fig. 2 shows a sectional view of the armed mechanism of the specific ammunition.
- B1879WO Fig. 3 represents the position of the different parts of the mechanism just before the ejection of the specific ammunition.
- 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.
- the ammunition comprises:
- 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.
- 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.
- this axis is molded with the body and is made so that its face (32) does not interfere with the introduction of the munition.
- the front face of the piston (6) does not touch the face (32) of the axis (20).
- 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.
- 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).
- the dimensions of the compression chamber vary according to the desired power.
- 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).
- 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) will engage the face (14) of the piston (24), urging the piston (24) to compress the air of the compression chamber (26).
- valve (48) 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.
- the valve 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.
- the valve locks at the end of its translation thanks to a locking system.
- 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.
- FIGs 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).
- 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.
- 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.
- the portions (94) and (93) have a suitable shape so that the axis (91) communicates the translation to the axis (85).
- the cycle described in the previous phases is repeated until there is no more ammunition.
- the number of ammunition corresponds to the number of marbles.
- the mechanism may have a body having a plurality of compression chambers (6) and therefore a cylinder head having the corresponding piston number (24).
- the pneumatic mechanism can be actuated by a blank ammunition. This
- 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.
