Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toy air gun for blowing a plastic or the like by gas pressure. More specifically, the present invention relates to a so-called blow-back system in which a breech hole protrudes rearward each time a bullet is fired. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toy air gun provided with a burst mechanism in a toy air gun that can be set to burst shooting or semi-auto shooting by a selector.

[0002]

2. Description of the Related Art Conventionally, various blowback toy air guns have been developed. In this blowback toy air gun, when the trigger is pulled, the hammer hits the release valve, the release valve opens, gas is ejected from the gas pressure chamber, the cylinder chamber is filled with gas, and the piston's through hole Or, it flows into the bullet holding chamber in front of the cylinder chamber through the outer peripheral groove, and the bullet mounted in the bullet holding chamber is fired, and the piston is pushed rearward about this, causing the breech to retract backward from the gun body. , Then it returns to its original position with the force of the recoil spring.

[0003] One cycle is a state in which the breech hole retreats and projects so as to be shifted at the upper end of the gun body, and moves forward and returns to its original state. Therefore, if you try to blow back and shoot a bullet again, you will trigger again. If you want ten cycles, you trigger ten times. This is called semi-auto shooting. On the other hand, when the trigger is fired once, two or three bullets are fired. The firing of a medium bullet while the trigger is being fired is called fully automatic shooting.

[0004]

The conventional blowback type toy gun has only a semi-automatic shot, and even if it is desired to continuously fire the bullets, the trigger has to be pulled every cycle, which is inconvenient. It was supposed to be.

[0005] The present invention has been made in view of these points, and by providing a burst mechanism in such a blow-back type toy gun, a single trigger can be performed by pulling the trigger once. Another object of the present invention is to provide a toy gun that can shoot out with a toy, and a toy air gun that can also perform semi-automatic shooting by switching.

[0006]

Therefore, in the invention of claim 1, when the trigger is pulled, the sear locking the raised hammer is interlocked to release the locking and the energy is accumulated. When the hammer rotates, the hammer directly or indirectly hits the release valve of the gas pressure storage chamber to open the valve, and gas is released from the gas pressure storage chamber into the cylinder chamber, whereby gas is released from the cylinder chamber. In a blowback toy air gun that emits and shoots a bullet mounted in the bullet-holding chamber, and the piston in the cylinder chamber moves back and forth to move the breech to the rear with respect to the gun body. By retreating, the hammer hits this and rotates,
Position the hammer so that it is raised,
One end of a first lever having a convex portion in a recess provided at the lower end of the playground is pivotally supported, and the beak tip of the first lever is provided on the side surface of the counter plate with each blowback operation of the playground. By engaging the blowback in several steps in order, lowering the counter plate downward, and by the lowering motion of the counter by the blowback for the few times, the shear is locked to the hammer raised by the breech bolt, and the counter The engagement between the plate notch and the beak tip of the first lever is disengaged.

According to a second aspect of the present invention, there is provided a blow-back type toy air gun similar to the first aspect, wherein the retreat of the play bottom causes the hammer to rotate and hit the hammer. With the hammer positioned, one end of a trigger bar is rotatably supported on the other end of the trigger supported on the gun body, and the other end of the trigger bar is supported substantially horizontally via a spring, A protruding shaft protruding from one side of the other end passes through a vertically long slot at the upper end of the vertically long counter plate. The counter plate has its upper end supported by the trigger bar, and its lower end is always supported by a spring for urging the counter plate upward.

A plurality of saw blade-like notches are provided on the upper side of one side of the counter plate, and a plurality of saw blade-like notches are provided slightly below the counter plate, and a link having a beak tip is provided at a position facing the lower notch. The link is always urged by a spring so that the tip of the beak meshes with any one of the lower notches. Also, the first hammer supported on the rotating shaft of the hammer
A hook bar is rotatably supported at the tip of the lever, and has a beak tip at one end of the hook bar which can be engaged with any one of the notches above the counter plate. The first lever has a protruding portion that can be fitted into a downwardly angled concave portion provided at the lower end of the play bottom, and a release spring that urges the convex portion to always fit into the angled concave portion of the play bottom is provided. Also, the operation of rotating the other end downward around the pivot portion at one end against the force of the spring of the trigger bar causes the shear to rotate, and the shear is locked to the hammer caused by the play bottom. Configuration.

According to a third aspect of the present invention, in addition to the configuration of the second aspect of the present invention, a second lever having one end fixed to a rotary shaft supporting the hammer and the first lever is provided. The lever is rotatable and free to rotate with the rotation shaft, and the second lever locks the tip of the hook bar to the hook bar so that the tip of the beak of the hook bar can be held away from the notch above the counter plate, The release bar, which presses a protrusion provided on one side surface of the trigger bar by turning the tip of the first lever downward and turns the free end of the trigger bar downward against a spring, is connected to the hook bar. It was configured to be pivotally supported.

[0010]

According to the first aspect of the present invention, when the trigger is pulled, the shear that has locked the raised hammer is released in conjunction with the shear, and the stored hammer rotates.
The hammer directly or indirectly hits the release valve of the gas pressure chamber to open the valve, and the gas is released from the gas accumulator into the cylinder chamber, whereby the gas is released from the cylinder chamber and the bullet is gripped. A bullet mounted in the chamber fires, and before and after this, the piston in the cylinder chamber moves to move the breech hole backward with respect to the gun body. In these operations, the retreat of the breech bolt causes the hammer to rotate and be raised, while the retreat of the breech bolt enters the convex portion of the first lever, which is in the recessed portion provided at the lower end of the breech bolt. Is pushed downwards,
The free end of the lever also rotates downward.

As a result, the beak end of the first lever sequentially engages with each blow gook from the lower part of the plurality of notches provided on the side surface of the counter plate, pushes down the counter plate, and blows back the free bottom a plurality of times. The downward movement of the counter plate causes the sear to be engaged with the hammer raised by the breech bolt, and the engagement between the notch of the counter plate and the tip of the lever is released. This terminates the burst with multiple bullet firings and blowback operations. Therefore, unless the trigger is retriggered, the bullet firing and blowback operations do not occur.

According to the second aspect of the present invention, when the trigger is pulled, the trigger bar is pulled in the trigger direction, and as described above, the sheer is pushed by the projection inside the rear portion of the trigger bar, and the shear is hammered. Unlock the lock. The stored hammer then opens the discharge valve of the gas accumulator directly or indirectly. As a result, gas is released from the gas pressure accumulating chamber into the cylinder chamber, and this causes gas to be released from the cylinder chamber and the bullet mounted in the bullet holding chamber is fired. Moves and the playground moves backward.

On the other hand, the end of the beak at one end of the hook bar enters the lowest notch at the top of the counter plate by moving the trigger bar in the trigger direction. The beak end of the link enters under the notch at the bottom. And the above-mentioned play bottom retreats while rotating and raising the hammer. Then, the convex portion of the first lever, which has entered the angled concave portion provided at the lower end of the retreating hammer, is pushed out, and the first lever pivots downward against the force of the release spring. The hook bar is lowered. The notch on the upper part is engaged with the tip of the beak of this lowering hook bar and pushes down the counter plate. At that time, the tip of the beak of the link escapes later as the counter plate falls, and enters the first notch from below.

[0014] Also, by the play bottom retreated to the specified position,
The hammer is completely raised, the release valve, which has been locked open, closes and the release of gas stops. The play bottom is returned to the home position by the force of the recoil spring, and the protrusion of the first lever enters the chevron recess of the play bottom by the return of the play bottom. With the upward movement of the first lever, the tip of the beak of the hook bar enters the second groove from under the notch at the top of the counter plate. At this time, the trigger is pulled, the trigger bar is also moved, and the shear is removed, so that the raised hammer is not locked and rotates in a manner to chase the breech hole. The rotated hammer again strikes the discharge valve to open it. The outgassed gas enters the cylinder chamber again, and the bullet is fired, and the breech hole retreats.

In this way, each time the bullet is fired and the breech floats back, the counter plate lowers, and the beak tip of the hook bar rises up from each step of the notch on the upper part of the counter plate and comes off the notch. Also, the counter plate goes down like this, but the trigger bar does not go down because the projection of the trigger bar is in the slot of the counter plate. However, at the time of the blowback of the breech hole for the third time, the protrusion of the trigger bar is located at the upper end of the long hole of the counter plate, and the free end of the trigger bar is pulled downward by the downward movement of the counter plate to resist the force of the spring. To rotate. Then, the projection inside the rear part of the trigger bar comes off from the shear, and the shear rotates and locks with the hammer raised by the play bottom. This terminates the burst. When the trigger is released, the trigger bar returns to the rear, the counter plate also returns to the rear, and the beak end of the link comes off. In this way, it is in the initial position.

According to the third aspect of the present invention, there is provided the second aspect of the present invention.
In addition to the action of the invention of the item, by rotating the second lever,
The second lever is locked with the beak tip at one end of the hook bar separated from the notch above the counter plate. When the trigger is pulled in this state, the trigger bar is pulled in the trigger direction, and as described above, the sheer is pushed by the projection on the rear inner side of the trigger bar, and the shear releases the hammer. The stored hammer then opens the discharge valve of the gas accumulator directly or indirectly. As a result, gas is released from the gas pressure accumulating chamber into the cylinder chamber, and this causes gas to be released from the cylinder chamber and the bullet mounted in the bullet holding chamber is fired. Moves and the playground moves backward.

As a result, the convex portion of the first lever is pushed out of the chevron-shaped concave portion of the play bottom, the tip of the first lever pivots downward, and the release bar pivotally supported by the hook bar supported by the first lever obliquely moves downward. , And presses a projection provided on one side surface of the trigger bar. As a result, the trigger bar rotates downward against the force of the spring, the protrusion inside the rear part of the trigger bar disengages from the sear, the sear rotates, and is locked by the hammer raised by the breech bolt. To do. The retracted bottom is advanced by the recoil spring and returns to the home position. Then, the convex portion of the first lever enters the chevron concave portion of the free bottom by the force of the spring, and the trigger bar is also pulled up to return to the original position.

Next, the details of the slide cover 15 and the cylinder chamber 16 will be described with reference to FIG. 2. A frame-shaped slide block 21 having a rear end face is fixed in the slide cover 15, and the rear end face of the slide block 21 is fixed. To the rear end of the piston 22 and is fixed by screws 23. Further, the cylinder chamber 16 is slidably supported in the slide block 21 in the front-rear direction. The piston 22 is slidably fitted into the cylinder chamber 16 from the rear end opening of the cylinder chamber 16. ing. The cylinder chamber 16 has a front end and a notch 16a at the lower end following the front end, and a gas inlet 16b is provided in the middle of the lower part. The gas injection port 16b is closed by the elastic nozzle 10 when the cylinder chamber 16 is in a fixed position.

The outer diameter of the piston 22 extends in three stages from the front end to the rear end, and the vertical hole 24 penetrates in three stages in the longitudinal direction substantially in accordance with the outer diameter. The inner piston 2 is inserted into the smallest vertical hole 24a provided at the front end thereof.
5 is slidably inserted, an O-ring 26 is provided on the outer periphery of the rear part, and a rear part of the O-ring 26 is inserted into a medium-diameter vertical hole 24b. Is sealed. A piston end 27 is inserted and filled in the large-diameter vertical hole 24c and fixed. Therefore, the screw 23 is screwed to the piston end 27.

The O-ring 2 in the vertical hole 24b having the medium diameter is provided.
Between the piston end 6 and the piston end 27, there is provided a piston inner spring 28 which constantly urges the inner piston 25 forward and positions the O-ring 26 at the step between the medium-diameter vertical hole 24b and the small-diameter vertical hole 24a. ing. In this state, there is a gap between the rear end of the inner piston 25 and the piston end 27, and the inner piston 25
Is slightly projected from the tip of the piston 22. Further, the inner piston 25 has a vertical hole 29 from the front end surface thereof to the middle thereof, and horizontal holes 30 extending from the inner end of the vertical hole 29 to both outer peripheral sides of the inner piston 25 are drilled.

On both sides of the outer circumference of the medium diameter portion of the piston 22, there are provided horizontal holes 31 reaching the vertical holes 24b of medium diameter, and the inner piston 25 resists the force of the piston inner spring 28. When the rear end of the inner piston 25 is brought into contact with the front end of the piston end 27, the positions of the lateral holes 30 of the inner piston 25 coincide with each other. Note that, in FIG. 2, these lateral holes 30 and 31 are displaced by 90 degrees, but this is illustrated for the sake of easy description, and they actually coincide. The cylinder chamber 16 is restricted from sliding forward by a slide stopper 32 provided in the slide cover 15, and the rearward slide is restricted by the rear end surface of the slide block 21. In FIG. 1, a recoil spring 34 is wound around a guide shaft 33 provided parallel to the barrel 12, and the recoil spring 34 returns the slide cover 15 to its original position when the slide cover 15 blows back due to gas pressure. It is urged to return.

In the case of this embodiment, in order to fire the bullet 6, by pulling the trigger 17 from the ready state for firing shown in FIG. It rotates by force and hits the impact plate 20, which causes the discharge valve 9
Press. As a result, the discharge valve 9 is pushed against the force of the spring, and the gas discharge path 11 is opened. Therefore, the vaporized gas generated and stored by the liquefied gas filled in the gas storage chamber 4 passes through the discharge valve 9 through the discharge valve 9 and the injection port 16.
The cylinder enters the cylinder chamber 16 through b. Then, the gas enters the lateral hole 31 of the piston 22, the lateral hole 30 of the inner piston 25, and the vertical hole 29 of the inner piston 25 in the cylinder chamber 16, and flies the bullet 6 closing the front end face of the vertical hole 29. Thus, the bullet 6 is fired from the muzzle through the inner barrel 13 as shown in FIG.

When the bullet 6 is fired, the inner piston 25 is no longer pressed, and the O-ring 26 is forced by the force of the piston inner spring 28 so that the O-ring 26 has a small diameter vertical hole 24a.
Until it hits the step at the boundary between the vertical hole 24b and the middle diameter vertical hole 24b.
As a result, the lateral hole 30 of the inner piston 25 shifts forward as shown in FIG. Then, the gas enters from the lateral hole 31 of the piston 22 to the vertical hole 24 b of the medium diameter of the piston 22 and presses the front end face of the piston end 27. Thus, the piston 22 is pushed by the gas pressure, and the slide cover 15 blows back against the force of the recoil spring 34. At that time, as shown in FIG. 5, the cylinder chamber 16 is left for a while, and the bullet 6 is pushed up from the magazine part 3 during that time, and the cylinder chamber 16 is
Of the bullet gripping chamber 14 enters through the notch 16a
Is located after.

Then, as shown in FIG.
When the slide stopper 32 of No. 5 reaches a position where it comes into contact with the end of the cylinder chamber 16, the piston 22 moves to the cylinder chamber 1
Exit from 6 and discharge the used gas. Further, as shown in FIG. 6, the cylinder chamber 16 is also moved backward by being locked by the slide stopper 32. Then elastic nozzle 1
From 0, the gas inlet 16b of the cylinder chamber 16 also comes off.
In addition, by retreating the slide cover 15, the hammer 1
8 happens. Even if the slide cover 15 moves forward, the state of the hammer 18 is maintained by a shear (not shown). Immediately after this, the discharge valve 9 closes the discharge path 11 and the injection of the vaporized gas from the gas pressure chamber 4 to the cylinder chamber 16 is stopped, but the piston 2 that is rapidly retreating is stopped.
2 and the slide cover 15 continue the backward movement due to the movement inertia.

Upon completion of the retreat, the slide cover 15 advances by the force of the recoil spring 34, the tips of the piston 22 and the inner piston 25 push the rear part of the bullet 6, and at the same time, the front end of the cylinder chamber 16 grasps the bullet. It hits the rear end of the chamber 14 and the cylinder chamber 1
The piston 22 and the inner piston 25 project outward from the notch 16a at the front end of the
Inside, the bullet 6 is pushed into the bullet gripping chamber 14. This completes the preparation for launching the next bullet 6. Therefore, when the trigger 17 is pulled again, the bullet 6 is fired, and the slide cover 15 blows back. The above is a so-called semi-automatic mechanism in which when a trigger is pulled, a bullet fires once and the slide guide blows back once.

By pulling the trigger as described above, while the bullet is being fired and the slide cover blows back, the discharge valve of the gas pressure accumulating chamber is opened and the hammer is closed. 7 to FIG.
