Description

  The present invention relates to a detonator and blowback model gun installed in a chamber of a blowback model gun.

  2. Description of the Related Art Conventionally, blowback-operated model guns are known in which a cartridge case loaded in a magazine is automatically fired into a barrel automatically and sequentially by the explosive force of gunpowder.

  The main part of the detonator method, which is the first method of the blowback operation method, is composed of only an empty cartridge type cartridge equipped with a detonator and explosive which is a long and narrow bar-shaped pre-fired needle provided in the chamber. . In the detonator method, most of the pyrophoric gas is discharged to the outside through the gap between the detonator and the cartridge, so there is a problem that the explosive pressure loss of the gunpowder is large and a heavy slide cannot be moved. Further, the gap between the detonator and the cartridge caused excessive accumulation of explosive combustion debris, resulting in early loading failure due to this. Patent Document 1 is an example in which such a problem is solved.

Utility Model Registration No. 3150763

  The blowback model gun disclosed in Patent Document 1 is made of an elastic material that expands only when the head of a detonator installed in the barrel receives the ignition pressure of gunpowder. The head of the detonator made of the elastic material is expanded by the ignition of the gunpowder and is in close contact with the inner surface of the outer shell. Therefore, theoretically, the release of the ignition gas from the ignition gas can be reduced, and the loss of the initiation pressure can be reduced. It was expected.

  However, in reality, the expected effect was not seen, and the loss of the initiation pressure could hardly be reduced. In addition, excessive accumulation of explosive combustion debris occurred in the same way, and the problem of early loading of poor loading could hardly be solved.

  The plug fire method, which is the second method of the blow back operation method, includes a detonator and a cartridge as in the case of the detonator method, but is different in that it has a firing portion serving as a driving force for the blow back operation inside the cartridge. According to the plug fire method, the above-mentioned problem can be solved more reliably without making the head of the detonator out of an elastic material. Further, the molding of the cartridge has an advantage that the processing accuracy as high as that of the detonator method is not required.

  However, none of the methods has solved the problem of explosive explosives that occurs during continuous firing or user operation. Moreover, the problem of the explosive of the gunpowder due to the sliding of the cartridge generated in the chamber has also occurred at the same time.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a detonator that drastically reduces the explosive and non-explosive explosives when handling a blowback model gun.

  In order to achieve such an object, a detonator according to the present invention is a blowback having a protrusion for abutting a firing pin in a cartridge case and a holding member for fixing the protrusion to an insert in a barrel. A detonator for a model gun, characterized in that an elastic body is provided at the joint between the protrusion and the holding member.

  According to the present invention, it is possible to provide a detonator that dramatically reduces the explosive and non-explosive explosives when handling blowback model guns.

  FIG. 1A is a perspective view of a cartridge according to this embodiment, and FIG. 1B is a cross-sectional view of the cartridge.

  The warhead 1 and the case 2 are screwed together by a screwing portion 4. In this embodiment, since the material of the warhead 1 is brass and the material of the case 2 is aluminum, the fastening force is stronger and the screwing portion 4 is less likely to loosen compared to a case where the material is formed of the same kind of metal. ing.

  In addition, since the center of gravity of the cartridge case shifts to the warhead side as compared with the case where both are made of brass, the cartridge case rotates more greatly at the time of removal, and follows a flight path close to a real bullet. The fact that the weight of the cartridge 3 is almost the same as that of the empty case also contributes to such a flight path.

  FIG. 2A shows a state in which the firing portion (inner) 8 is pushed into the cartridge by the dedicated loader 7.

  The user inserts the primer 10 into the case 2 in advance, fits the case bottom port 6, and places the gunpowder cap 10 filled with the gunpowder 11 above it. Further, the firing pin portion 8 is inserted into the case 2.

  Since the firing pin unit 8 includes an O-ring 9 that is in close contact with the inner surface of the cartridge 3, a certain amount of pressing force is required at the time of insertion, and it is difficult to place the gunpowder 11 above the explosive 11 without the loader 7. The loader 7 is used by attaching a safety tube 14 for avoiding the possibility that the firing portion 8 touches the explosive and ignites. In the present embodiment, the O-ring 9 is made of rubber.

  FIG. 2 (b) shows a state in which the back surface of the firing pin unit 8 is pushed into the case 2 by the loader 7 and placed, and then the warhead 1 is screwed into the case 2. Hereinafter, this state is referred to as a cartridge case.

  Since the space 15 is sealed by the adhesion of the O-ring 9 to the inner side surface of the cartridge 3, the discharge of explosive gas to the outside is suppressed. In addition, the O-ring 9 has an effect of suppressing sliding of the firing needle portion 8 and the like inside the cartridge 3.

  FIG. 3 shows a state where a plurality of cartridge cases are loaded in the magazine 22 and the magazine 22 is installed on the frame 26.

  The magazine 22 has a configuration in which a magazine follower 24 supported by a magazine spring 23 is elastically biased upward. The magazine follower 24 above the magazine spring 23 is provided with a certain inclination. This inclination is used when the user slides the slide 16 or restores the slide 16 after blowback, and the cartridge mouth of the cartridge case is projected from the detonator 18. It is for covering the part completely.

  A detonator 18 having a cartridge control spring 29 is provided in a chamber 44 at the rear of the barrel 17. On the rear side of the gun bottom surface 27 at the rear part of the slide 16, a lower pin 19 that slides forward under the impact force of the hammer 20 is provided.

  FIG. 4 shows a state when the user slides the slide 16 of the blowback model gun backward. The hammer 20 is pressed against the rear portion of the slide 16, rotates backward about the shaft 28, and is fixed at a position that does not hinder sliding of the slide 16.

  When the user releases the hand from the slide 16 or loosens the force, the slide 16 is pushed back by the elastic force of the recoil spring 25. In this process, the bottom bottom portion 33 of the bottom surface 27 of the gun bottom surface 27 abuts against and presses the upper shell bottom 32 of the cartridge case 31, so that the cartridge case 31 is pushed upward and obliquely forward.

  FIG. 5 shows the moment when the cartridge mouth of the cartridge case 31 covers the protrusion of the detonator 18 in the process in which the slide 16 is pushed back by the elastic force of the recoil spring 25.

  In the present embodiment, the protrusion of the detonator 18 has a substantially perfect cross section, and the diameter decreases toward the tip. The tip of the protrusion of the detonator 18 is processed to be thin in order to realize smooth bullet feeding. The side surface of the projecting portion of the detonator 18 is subjected to smooth processing for smooth feeding of the cartridge case 31.

  FIG. 6 shows a state where the cartridge 31 is fed to the detonator 18.

  The cartridge case 31 is vigorously fed into the chamber 44 by the series of flows shown in FIGS. Conventionally, there have been many outbursts during such ammunition, but the detonator 18 according to this embodiment is provided with the cartridge control spring 29 so that the energization of the cartridge case 31 is buffered. It can be drastically reduced.

  Here, problems in the conventional blowback model gun will be described with reference to FIG.

  FIG. 10 shows a state in which the cartridge case 55 is installed in the chamber 56 by the same flow as in FIGS. The gaps 51 and 52 are caused by a processing error due to a clearance at the time of forming each part (a gap between tools used for a metal mold in plastic processing). The gaps 51 and 52 have been regarded as a problem as a cause of explosive or non-explosive explosives.

  As a first problem, explosive explosives that occur during explosive fires and user operations are cited.

  When the user releases the hand after sliding backward, the cartridge case 55 moves from the upper part of the magazine to the chamber 56 while being accelerated by the elastic force of the recoil spring. Therefore, in most of the conventional configurations, the firing pin 58 in the cartridge case 55 collides with the protrusion of the detonator 57, causing an accidental explosive explosive explosion.

  Of course, the user can slowly restore the slide forward after sliding backward, but this not only complicates the operation but also does not provide a sense of realism.

  In addition, after blowback, which will be described later, the explosive gas of gunpowder is used as the motive power, so that the restoring speed of the slide due to the elastic force of the recoil spring becomes faster, and the firing portion of the cartridge 55 at the tip of the protrusion of the detonator 57 Since the impact force at the time of collision of 58 becomes larger, it can be said that the explosiveness of explosive explosives is higher than when the first bullet is supplied.

  Furthermore, the chamber 56 has a slightly larger inner diameter than the outer diameter of the cartridge case, and its side surface is formed to a certain degree of smoothness for smooth feeding of the cartridge case. That is, since the cartridge case is not restrained at all in terms of sliding in the chamber 56, the state of FIG. 10 (a) in which a gap 51 is generated between the protrusion tip of the detonator 57 and the rear surface of the firing pin 58, The state shown in FIG. 10B in which the gap 53 is generated between the gun bottom surface 59 can be freely slid.

  Under such circumstances, when the muzzle of the blowback model gun is directed downward from the horizontal state (the state of FIG. 10A), the cartridge case 55 slides forward in the chamber 56 and The back surface collides with the protrusion tip of the detonator 57 (state shown in FIG. 10B).

  Since the explosive for toys may ignite with a slight shock, conventionally, even when the muzzle is directed downward, the explosive explosive occurs due to the stimulus given by the tip of the firing pin.

  The second problem is the failure of gunpowder due to the sliding of the cartridge that occurs in the chamber. Therefore, the mechanism of gunpowder firing in the blowback model gun will be described.

  When the user pulls the trigger, the hammer rotates vigorously and hits the rear end of the lower pin. Therefore, the lower pin slides forward, and the tip of the lower pin 62 applies an impact force to the primer 60.

  Here, since the gunpowder 61 embedded in the gunpowder cap 63 is sandwiched between the primer 60 and the firing pin 58, the impact force applied to the primer 60 by the tip of the lower pin is transmitted to the gunpowder cap 63, and the gunpowder 61 is ignited when triggered by the tip of the firing pin 58.

  Therefore, in order to surely ignite the gunpowder, it is preferable that the user pulls the trigger in a state where the bottom portion of the cartridge case 55 and the gun bottom surface 59 are in contact with each other as in the state of FIG.

  However, as described above, since the cartridge case is slidable in the chamber, it is assumed that a gap 52 is generated as shown in FIG. 10B when the user pulls the trigger. In such a state, since the impact force of the lower pin 62 due to the hammer hit is not sufficiently transmitted to the primer 60, explosives do not occur.

  Thus, conventionally, the failure of gunpowder has often been attributed to the gap formed between the bottom of the shell and the bottom of the gun.

  In the present embodiment, the above two problems that have been troubled by users and developers have been solved by installing the cartridge control spring 29 in the detonator 18. FIG. 7 shows the detonator and its peripheral part according to the present embodiment.

  As shown in FIG. 7A, the cartridge control spring 29 is installed at the joint portion 39 of the detonator 18 and the holding member 36, and the spiral shape of the cartridge control spring 29 increases from the joint portion 39 toward the tip of the projection portion 35. The coaxial radius is spread. The holding member 36 is embedded in the insert 37 as shown in FIG.

  According to the detonator 18 according to the present embodiment, when the cartridge case 31 biased after the user slides the slide 16 or blows back is vigorously fed into the chamber 44, the protruding portion of the detonator 18 protrudes. The head of the cartridge case 31 comes into contact with the cartridge control spring 29 before colliding with the hitting part 8. Therefore, the urging force of the cartridge case 31 is buffered by the repulsive force of the cartridge control spring 29, and explosive explosives can be drastically reduced (elimination of the first problem).

  Further, as shown in FIG. 7B, the cartridge control spring 29 causes the gun bottom 27 and the bottom of the cartridge case 31 to be in close contact with each other by elastic force, thereby preventing the occurrence of explosives, which was the second problem. be able to.

  Here, the blowback operation method of the blowback model gun according to the present embodiment will be described.

  In the blowback model gun, the slide is slid backward using the ignition gas in the shell as the power, the shell is discharged from the discharge port, and then the slide is slid forward by the elastic force of the recoil spring. The At that time, the next cartridge case in the magazine is automatically fired into the barrel, so it can be fired continuously.

  FIG. 6 shows a state in which the cartridge case 31 is fed into the chamber 44 by the user sliding backward on the slide 16 as described above. As described above, since the energizing force of the cartridge case 31 is buffered by the repulsive force of the cartridge control spring 29 during such bullet feeding, the explosive explosive is reduced.

  In the state shown in FIG. 6, when the user pulls the trigger 21, the hammer 20 pivots vigorously around the shaft 28 and strikes the lower end of the lower pin 19 as shown in FIG. The impact force of the impact is transmitted to the primer 12 by sliding the lower pin 19 forward.

  In the present embodiment, the bottom of the cartridge case 31 is in close contact with the gun bottom surface 27 due to the elastic force of the cartridge control spring 29, so that the impact force caused by the hammer 20 impact is directly transmitted to the primer 12. Therefore, the gunpowder 11 in the gunpowder cap 10 is surely stimulated and ignited by the firing pin 8.

  Since the space 15 is an airtight chamber by the O-ring 9, the ignition gas generated by the ignition of the explosive 11 becomes an explosion pressure without being released to the outside, and slides the slide 16 backward.

  FIG. 9 shows a state where the slide is slid backward by the explosive pressure of the explosive.

  The explosive pressure of the explosive gas from the explosive causes the cartridge 31 to be discharged from the discharge port 50 after sliding the slide 16 backward.

  Since the cartridge case 31 according to the present embodiment is composed of a brass warhead and an aluminum case, the torque increases due to the deviation of the center of gravity, and the cartridge case 31 is swept away while rotating greatly. As a result, it is possible to experience a feeling of use that is visually close to a real bullet.

  When the slide 16 is pushed back forward by the elastic force of the recoil spring 25 after the cartridge case 31 is discharged, the bottom bottom 33 of the gun bottom surface presses the upper case portion 42 of the cartridge case 41 as the next bullet, As it is, it is pushed upward and obliquely forward and fed into the chamber 44.

  Since the slide speed of the slide 16 in the rear direction is faster in the case of using an explosive gas of gunpowder (when the first bullet is supplied) than in the case of operation by the user (when the first bullet is supplied), the recoil spring The restoring speed of the slide 16 by the elastic force of 25 is also increased. Therefore, since the urging force when the cartridge case 41 is fed into the chamber 44 also increases, conventionally, there is a high possibility that the tip of the detonator projection protrudes from the back of the firing needle portion when the next bullet is fed. In addition, the impact force at the time of the collision also increased, so the possibility of an outburst was higher than when the first bullet was supplied.

  In this respect, the detonator 8 according to the present embodiment can drastically reduce the explosion even after blowback because the cartridge control spring 29 buffers the urging of the cartridge case 41.

  As described above, according to the detonator 8 including the cartridge control spring 29 according to the present embodiment, it is possible to protect the user from the danger of explosive explosives and to reduce the irritation of the user due to the explosive explosives as much as possible.
