Definitions

• This invention relates to a pneumatic firing system, particularly to a paintball or airsoft gun capable of firing individual projectiles or enabling continuous firing.
• the weapon imitates a real weapon in its functions and appearance.
• Paintball guns work in such a way that the magazine releases the paintball ball, which enters the gun barrel.By pressing the trigger, you release the so-called bolt, which by its movement inside the weapon lets compressed air or CO 2 intothe barrel behind the paintball. It expands sharply when heated, and very quickly "expels" the ball out of the barrel of the paintball gun.
• This system varies according to the exact type of weapon and allows several modes of firing.It is mainly a semi-automatic gun that allows one shot per one press of the trigger, or a fully automatic weapon, which enables automatic firing for the duration the trigger is pressed.
• Document TWM547097 can be considered the most similar state of the art, as it is a technical solution of a mechanical paintball gun capable of continuous firing. At the same time,however,the ballmagazine system in that document does not offer any innovative solution.
• the essence of the present invention is a system enabling paintball or airsoft projectiles to be shot, depending on the installed set and size of the parts.
• the system works on compressed air and mimics the function of a real weapon,where the weapon feeds ammunition from the magazine into the chamber and only then is it possible to fire.
• the system fully simulates the control of the real weapon and the mode of actual firing, where you can shoot projectiles in semi-automatic or automatic mode (multiple projectiles in a row).
• the pneumatic system works, as there is a small amount of recoil.
• the automatic firing mode of the system is mechanical, which means that it does not have to be complicated to adjust, the speed of the projectiles does not decrease, and their range does not change. It works smoothly thanks to a locking lever, a safety detainer of the projectile feeder, and the projectile feeder. If the ammunition in the magazine runs out,the mechanism stops and waits for a loaded magazine to be inserted or further handling. It is similar to the operation of a real weapon.
• Other improvement features or advantages of the present invention include simple disassembly of the weapon using only one Allen key and the truly realistic appearance similar to the AK47 rifle.
• the essence of the invention is, inter alia, to provide the system with another automatic firing mode, which differs from the prior art in that it eliminates the disadvantages consisting particularly in complicated speed setting, or, in case of electrically controlled automatic systems, in elimination of the use of a battery as a power supply.
• the marker designed herein is able to automatically shoot one projectile after another in rapid succession.
• Markers according to the prior art have a projectile feeder, the so-called bolt, connected to a hammer by means of a steel wire. This allows them to move forward together when the trigger is pressed, then they hit a prepared projectile, which is caught only by a rubber safety detainer and waits for the supply and impact of the air burst. Without this rubber safety detainer, all ammunition would move straight into the barrel. After the impact, the projectile feeder pushes the projectile into the barrel and thus pushes it through the projectile rubber safety detainer. The hammer strikes the valve, which releases the air which hits the projectile, and it flies out of the marker.
• the hammer with the projectile feeder starts to move back to the rear position and another projectile falls in front of the projectile feeder.Therefore, when the magazine is removed, the aimunition may fall out or the projectile may be disturbed by the projectile feeder's impact and shooting becomes inaccurate.
• the pneumatic firing system according to the invention ensures the smooth operation of the device by the use of the following components:
• a firing node lever (15) according to Fig. 1 is used in prior art markers and allows firing modes to be switched. For our marker, we modified its function to switch between firing modes and improved the mode - automatic.
• the firingmode lever (15)in the system according tothe invention has 3positions; the first position in the "locked” mode, see Fig. 2, then the second position in the "automatic”mode, see Fig.3 and the third position in the mode of single shots or semi-automatic, see Fig.4.
• the firing mode lever (15) is connected to a skirt (33),which comprises cut-outs, and thus affects the function of the trigger (25)and allows changing of the firing mode.
• the trigger (25) In the third position, the trigger (25) must always be released and pressed again after each shot, thus resetting itself.In the second position we hold the trigger (25) until the cocking lever (4), the so-called bolt, stops in the first position - in the middle, see Fig.5.
• the cocking lever (4) has three positions, namely,position 1 - in the middle, see Fig 5, position 2 - at the rear, which is not a permanent position, see Fig. 6, and position 3 - at the front, see Fig.7.
• valve (38),Fig.8, 9, 10, contained in the system according to the invention was provided with 6 additional drilled holes and its dimensions were reduced compared to the known prior art.
• the reduced size of the valve (38) and the separation of the hammer (47) allowed us to insert one new component into the internal system,namely a cocking cylinder (46).Thesemodifications allowedbetter pressure throughput to the cocking cylinder (46) and its cocking.
• the cocking cylinder (46), see Fig. 11, 12, is a completely new component that is included in the system according to the invention and is not known from any prior art solution.It is a cylindrical part with a hole in the middle which is inserted in the internal system between the valve (38) and the hammer (47) so that the hammer (47) can strike the needle (39) in the valve (38) via the cocking cylinder (46), thus releasing air further to the projectile.
• the cylinder (46) is connected by a pull-rod (56) to the projectile feeder (35).
• the cocking cylinder (46) allows the hammer (47) to be cocked and secured behind the locking lever (50).
• the lugs on the projectile feeder ensure the delivery of only one projectile at a time into the chamber.
• the feeder (35) moves with the projectile.This ensures that no further projectile is delivered to the chamber.
• the entire system inside the marker is cocked backwards and the projectile is fed into the chamber, where it waits for another firing.
• the safety detainer (34) of the projectile feeder, the so-called lockbolt, see Fig. 15, is used in the marker system according to the invention for a different function than that which it performs in prior art solutions.
• the locking lever (50) in Fig.16 and 17 is a newly developed part which not only locks the hammer in automatic firing mode,but also locks it before firing. If the projectile is not loaded in the chamber, it is not possible to fire the gun by pressing the trigger (25).
• the locking lever (50) isunlocked (when moving forward) only by the pull-rod (56) which connects the cocking cylinder (46) and the projectile feeder (35).
• the locking lever (50) is locked by means of the spring (51) of the locking lever at the moment when the hammer (47) returns again, thus waiting for further handling of the marker.
• the hammer detainer (32) in Fig. 18 is a well-known component. In the solution according to the invention, it was used and modified for use in automatic firing. In a competitive solution, the hammer is only blocked by the hammer detainer,both in automatic and semi-automatic mode. Our marker uses the known hammer detainer (32), and its function was adjusted for both firing modes.
• our device uses the hammer detainer (32) to secure the hammer (47)after the pull-rod (4)moves toposition 3 - forward and the projectile is fed into the chamber.
• the hammer (47) is secured by the locking lever (50), which is unlocked by the pull-rod (56) when it moves forward.
• the hammer detainer (32) folds into the body (1) and unlocks the hammer (47), which moves forward, and the hammer detainer (32) returns to its original position. The unlocked hammer (47)moves further forward, and the gun can be fired.
• the hammer (47) is secured only by the locking lever (50) and the hammer detainer (32) folds into the body (1) of the marker when the trigger (25) is pressed and held and remains in the body (1) until the trigger (25) is released or there is no ammunition in the magazine.
• a locking lever (50) is added to lock it.
• the hammer (47) moves from the locking lever (50), by means of the pull-rod (56) to the hammer detainer lever (32) and waits for the trigger (25) to be pressed.
• the hammer (47) is moved by means of a hammer spring (48).
• the hammer (47) When the trigger (25) is pressed and held, the hammer (47) is released from the hammer detainer (32), which remains in the body (1) of the marker, and the hammer (47)directly strikes,via the cocking cylinder (46), the needle (39),which is in the valve (38). This releases air (see Figures 22 and 23) and the projectile is fired from the marker.
• the cocking cylinder (46) connected by the pull-rod (56)to the projectile feeder (35) and the cocking lever (4) begins to be pulled backwards by pressure.
• the pull-rod (56) moves the hammer (47)backbehind the locking lever (50)and a new projectilemoves in front of the projectile feeder (35).At this moment, the cocking cylinder (46) with theprojectile feeder (35)begins tomove forward,thereby releasing thepullrod (56) to release the locking lever (50) and releasing the hammer (47), which does not stop on the hammer detainer (32)but moves forward straight on the needle
