Abstract

The pneumatic firing system includes a valve (38), a projectile feeder (35), a separately operating hammer (47), a hammer retainer (32), a cocking cylinder (46), a locking lever (50), a firing mode lever (15) with the automatic position and a safety detainer (34) of the projectile feeder. This system allows you to shoot paintball or airsoft projectiles, depending on the installed set and the size of the parts. The system works on compressed air and mimics the functions of a real weapon, where the weapon feeds ammunition from the magazine into the chamber and only then is it possible to fire.

Description

Pneumatic firing system
Field of the invention
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.
Background art
For the time being, there exist two main simulations of real tactical combat using air, gas, or electric models of real weapons. First, there is an airsoft system, which fires plastic projectiles.And second, a paintball system, where you shoot balls filled with paint to ensure that the impact is marked.
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 CO2 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.
Furthermore, two solutions of the projectile hopper system are known.The ordinary arrangement, with the location of the projectile hopper on the top of the weapon, and also a less frequently used arrangement, which mimics a real magazine, which is located in the lower part of the weapon.At present, therefore, the most common bullet hopper system is a traditional gravity hopper located on the top of the weapon.The projectiles contained in it freely and with the help of gravitational force fall into the chamber of the weapon for immediate firing.
Existing technical solutions related to paintball or airsoft weapons are known in various designs.
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.
Another document describing the state of the art similar in certain respects to the presented technical solution is, for example, document US9803953, referred to as amechanicalpaintball gun.It is apaintballweapon enabling continuous firing.
There is also document No.CN201196553,which describes improved continuous firing equipment for BB balls and paintball guns.
There are also technical solutions related only to the charging mechanism or methods and solutions for changing a primarily airsoft weapon into a weapon suitable for paintball.
Conventional weapons on the paintball or airsoft weapons market do not provide a suitable solution for pushing the ball into the firing chamber and do not fully imitate the operation of real weapons - there is no recoil when firing paintball weapons or it is minimal for airsoft weapons.Current paintball guns do not solve the function of feeding balls directly into the chamber, and thus when removing the magazine, 1 to 2 balls fall out of the gun. The shortcomings of the current designs may also manifest themselves in a change in muzzle velocity of the projectile and in the range of the projectile.
Summary of the invention
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.
With known airsoft markers, it can occur that two projectiles are fed at a time. This can happen when a projectile is already in the chamber and the cocking lever ismanually pulled back and released forwards, a second projectile is fed into the chamber and the first is forced into the barrel. The present invention overcomes this disadvantage with a modified marker as described below.
Thanks to this system,which simulates the control of a real weapon, no ammunition falls out of the marker when the magazine is removed, and the cocking lever is pulled.However, if we insert the magazine and do not pull the cocking lever and then remove the magazine again, it will happen that one projectile falls out due to failure to feed the projectile into the chamber.
Even when manually pulling and releasing the cocking lever, a second projectile will notbe fed.One projectile will stillbe fed,thanks to the projectile feeder, until firing occurs, and the internal mechanism feeds a new projectile.
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). During firing, 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.
Thanks to the firing mode lever,which is moved to the middle second position, and to the improvement of some components, the marker designed herein is able to automatically shoot one projectile after another in rapid succession.
Smooth operation, not only in automatic fire, see Fig. 20, but also single-shot fire, see Fig. 21, 22 and 23, is ensured by means of the device described herein by modifying known parts and adding parts according to the invention.
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. After the shot, 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 modified valve (38),
- a modified projectile feeder (35), and
- a separate hammer (47),
- an approved function of a hammer detainer (32), and
- a cocking cylinder (46), a locking lever (50), the automatic mode position on the firing mode lever (15), and
- a safety detainer (34) of the projectile feeder, the so-called lockbolt, which performs a different function than that for which it is used according to the prior art.
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.
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.
The 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 projectile feeder (35) according to Fig. 14, the so-called bolt, which is modified in the device according to the invention by adding two catching projections at the end of the feeder (35), (Fig. 13), and connected by means of a pull-rod (56) to the cocking roller (46). It contrasts with the prior art, where the hammer is connected to the projectile feeder.
The improved feeder (35) with lugs on its end, see Fig. 13, after releasing the cocking lever (4) allows the projectile to be secured.The lugs on the projectile feeder ensure the delivery of only one projectile at a time into the chamber.When the lever (4) is cocked manually, the feeder (35) moves with the projectile.This ensures that no further projectile is delivered to the chamber. After the shot, 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. Competitive markers usually have a plastic lockbolt,but sometimes a steel one. In the case ofmarkers according to the prior art, they use this lockbolt to prevent dry firing. In our device, the safety detainer (34) of the projectile feeder ensures the projectile feeder (35) locks when the ammunition runs out, which does not allow feeding of the chamber without ammunition, and the cocking lever (4) is in position 1 - in the middle.The projectile always lifts our projectile feeder safety detainer (34) when charged into the chamber and unlocks it so that the projectile can be moved into the chamber depending on our internal system.
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.
In semi-automatic mode, 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. Before this happens, the hammer (47) is secured by the locking lever (50), which is unlocked by the pull-rod (56) when it moves forward. When the trigger (25) is pressed, 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.
In automatic mode, 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.
Smooth running of the hammer detainer (32) is achieved by a modified function of the trigger (25) and the skirt (33), which affects the function of the trigger (25), thanks to the cut-outs on the skirt (33).
The hammer (47), see Fig. 19, which in the case of markers according to the prior art moves together with the projectile feeder (35), is separated by the solution according to the invention and a locking lever (50) is added to lock it. This enables you to achieve smooth operation in automatic mode. When setting the firing mode lever (15) to automatic, i.e., position 2, with the cocking lever (4) moved to position 3 - front, 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).
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. After firing the projectile 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
(39).Everything is repeated until the trigger (25) is intentionally released or the ammunition in the magazine runs out, see Fig.20.
The magazine, see Fig. 24, is composed of known components of the prior art. However, a modification has been made to the top of the magazine, which involves the addition of a left-hand side clamp (71) and right-hand side clamp 72), which are located on the magazine housing (70). The clamps (71,72) ensure that no ammunition falls out when the cocking lever (4) is cocked, and the magazine is removed.However, this is not a patent claim.When inserting the magazine into the body (1), the magazine is unlocked by means of the unlocking cubes, which are located in the body (1) of the marker, see Fig.25.
Air supply, see Fig.26 and 26a is led over the rear part (3) in the marker of the system according to this invention.
The system parts can be joined to each other in combination with parts according to the prior art, which in one variant are the following parts of the marker, see Fig.27, 28, 29: a body (1), a front part (2) and a back part (3), the cocking lever (4), a barrel (5), a front sight (6), a ring (7) on the barrel, a barrel holder (8), a front shroud (9), a holder (10) of the upper wooden cover, an upper cover (11) and a lower wooden cover (12), a rear sight (13), a steel cover (14), a stock (16), a grip (17), a magazine retainer (18), a locking pin (19), a large pin (20) and a small pin (21) of the back part, a trigger pin (22), a pin (23), a screw (24) of the front part, a spacer (26), a shroud screw (27), a grip holder (28), a spring (29) of the hammer detainer, a trigger stop (30), a trigger spring (31), a connecting tube (36), a connecting tube pin (37), a needle (39), a needle carrier

Example for an embodiment of the invention
Thepneumatic firing system according to the invention ensures the smooth operation of the device by the fact that it contains:
- a modified valve 38,
- a modified projectile feeder 35, as well as
- a separately operating hammer 47,
- improved function of the hammer detainer 32, and
- a cocking cylinder 46, a locking lever 50, auto position of a firing mode lever 15, and
- a safety retainer 34 of the projectile feeder, the so-called lockbolt, which performs a different function than the one for which it is used according to the prior art.
The firing node lever 15 used in the system according to this invention has 3 positions, namely 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 the skirt 33, on which there are cutouts, and thus affects the function of the trigger 25 and allows switching of the firing mode.
In the third position, it is necessary to always release the trigger 25 after each shot and press it again, thus resetting the trigger. In the second position you must 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 i.e., position 1 - in the middle Fig. 5, position 2 - rear position, this is not a permanent position Fig. 6, and position 3 - front position, see Fig.7.
Thevalve 38,see Fig.8, 9, 10, contained in the system according to the invention was provided with 6 additional holes and its dimensions were reduced compared to the known prior art.The reduction of the valve 38 and the separation of the hammer 47 allowed us to insert one new component into the internal system, namely the cocking cylinder 46.These modifications allowed better pressure throughput to the cocking cylinder 46 and its cocking.
The cocking cylinder 46, see Fig. 11,12, is a completely new component and is included in the system according to the invention, and is not known from any prior art solution.It is a cylindrical componentwith a hole in the middle and isplaced in the internal system between the valve 38 and the hammer 47 so as to allow the hammer 47 to strike the needle 39 in the valve 38 via the cocking cylinder 46, thereby releasing the air furtherup to theprojectile.The cylinder 46is 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 projectile feeder 35, see Fig. 14, the so-called bolt, is modified in our device by adding two lugs at the end of the feeder 35, (Fig.13), and is connected by means of the pull-rod 56 to the cocking cylinder 46. It differs from the prior art solutions, which have a hammer connected to a projectile feeder.
The improved feeder 35 with lugs at the end of it, see Fig. 13, after releasing the cocking lever 4 allows the projectile to be detained. The lugs on the feeder ensure that only one projectile is fed to the chamber at a time.When the lever 4 is cocked manually, the feeder 35 moves with the projectile.This ensures that no further projectile is delivered to the chamber. After firing, the whole system inside the marker is cocked back and the projectile is fed into the chamber,where it waits for the next shot.
The safely detainer 34 of the projectile feeder, the so-called lockbolt in Fig. 15, is used in the marker system of the present invention for a function that differs from that which it performs in prior art solutions. Competitive markers usually have a plastic lockbolt,but sometimes a steel one. In the case ofmarkers according to the prior art, they use this lockbolt to prevent dry firing. In our device, the safety detainer 34 of the projectile feeder ensures locking of the projectile feeder 35 when the ammunition runs out,which does not allow feeding of the chamber without ammunition, and the cocking lever 4 is in position 1 - in the middle.The projectile always lifts our projectile feeder safety detainer 34 when fed into the chamber and unlocks it so that the projectile can be fed into the chamber depending on our internal system.
The locking lever 50, see Fig. 16 and 17, is a newly developed steel component that not only blocks the hammer during automatic firing,but also blocks it before firing.If the projectile is not fed into the chamber, it is not possible to fire by pressing the trigger 25.When moving forward, the locking lever 50 can only be unlocked 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 locking lever spring 51 at the moment when the hammer 47 returns again, thus waiting for further handling of the marker.
The hammer retainer 32, see Fig. 18, is a well-known component. In the solution according to the invention, it is used and modified for use in automatic firing. The competitive solution stops by means of the hammer retainer,both in automatic and semi-automatic mode.Our marker uses the well-known hammer retainer 32 and its function is modified for both firing modes.
In semi-automaticmode, our device uses the hammer retainer 32 to secure the hammer 47 as soon as the cocking lever 4 arrives at position 3 - forward, and the projectile is fed into the chamber.Before this happens, the hammer 47 is secured behind the locking lever 50, which is unlocked by the pull-rod 56 when moving forward.When the trigger 25 is pressed, the hammer retainer 32 is folded into the body 1 and the hammer 47 is unlocked so that it can be moved forward, and the gun fired.
In automatic mode, the hammer 47 is secured only by the locking lever 50. The hammer retainer 32, when the trigger 25 is pressed and held, folds into the body 1 of the marker and remains in the body 1 until the trigger 25 is released.
In order to achieve smooth running of the hammer retainer 32,we have modified the function of the trigger 25 and the skirt 33, which has an effect on the function of the trigger 25, thanks to the cut-outs in the skirt 33.
The hammer 47, see Fig. 19, which in the case of markers according to the prior art moves together with the projectile feeder 35, is, in the solution according to the invention, separated and the locking lever 50 is added to secure it. This enables smooth automatic firing.
When the firing mode lever 15 is set to automatic, i.e., position 2, and the cocking lever 4 is in position 3 - front,the hammer 47 reaches the hammer retainer 32 by means of the pull-rod 56 from the locking lever 50 and waits for the trigger 25 to be pressed.The hammer 47 is moved by the action of the hammer spring 48.
When the trigger 25 is pressed and held, the hammer 47 is released from the hammer retainer 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 will release the air (see Fig.22 and 23) and expel the projectile from the marker. After firing the marker, the cocking cylinder 46 connected by the pullrod 56 to the projectile feeder 35 and the cocking lever 4 begins to be cocked backwards by pressure.The pull-rod 56moves the hammer 47 back behind the locking lever 50 and a new projectile moves in front of the projectile feeder 35.At that moment, the cocking cylinder 46 with the projectile feeder 35 begins to move forward, and thus the rod 56 unlocks the locking lever 50 and releases the hammer 47,which does not stop on the hammer retainer 32,but moves forward straight onto the needle 39.Everything is repeated until the trigger 25 is deliberately released or the magazine runs out of ammunition.
The magazine shown in Fig. 24 is composed of known components of the prior art. Only the top of the magazine wasmodified by adding a left-hand clamp 71 and right- hand clamp 72, which are located on the magazine housing 70. The clamps 71, 72 ensure that no ammunition falls out when the cocking lever (4) is cocked, and the magazine removed.However, this is not a patent claim.When inserting the magazine into the body 1, the magazine is unlocked by means of the unlocking cubes, which are in the body 1 of the marker, see Fig.25. Air is supplied, see Fig. 26 and 26a, through the rear part 3 in the marker with the system according to the invention.
The system parts can be joined to each other in combination with parts according to the prior art, which in one variant are the following parts of the marker, see Fig.27, 28, 29: a body (1), a front part (2) and a back part (3), the cocking lever (4), a barrel (5), a front sight (6), a ring (7) on the barrel, a barrel holder (8), a front shroud (9), a holder (10) of the upper wooden cover, an upper cover (11) and a lower wooden cover (12), a rear sight (13), a steel cover (14), a stock (16), a grip (17), a magazine retainer (18), a locking pin (19), a large pin (20) and a small pin (21) of the back part, a trigger pin (22),a pin (23), a front part screw (24), a spacer (26), a shroud screw (27), a grip holder (28), a hammer detainer spring (29), a trigger stop (30), a trigger spring (31), a connecting tube (36), a connecting tube pin (37), a needle (39), a needle carrier (40), a needle packing (41), a needle spring (42), a valve cap (43), an valve cap O-ring (44), a valve 0- ring (45), a hammer spring (48), a hammer spring pin (49), a cocking lever spring (52), a cover holder (53), a pull-rod locking roller (54), a guide rod (55), a barrel pin (57), a grip screw (58), a valve locking pin (59), a muzzle velocity adjust screw 60), a back part O-ring (61), an O-ring (62), and a centering O-ring (63).
Furthermore, the system can be combined with other known parts according to the prior art, see Fig. 30, including: a right-hand side part (64) and a left-hand side part (65), a lower part (66) and an upper part (67), an upper lever (68) and a lower lever (69), a housing (70), a right-hand side clamp (71) and a left-hand side clamp (72), an unlocking cube(73), a spring (74) of the unlocking cube, an upper lever spring (75)and a lower lever spring (76), a main spring (77), a spring thrust cylinder (78), a clarrp pin (79), and an unlocking cube pin (80).
