The present invention relates to a toy gun provided with an automatic bullet supply mechanism for automatically supplying.

[0002]

2. Description of the Related Art A toy gun called an airsoft gun is usually formed so that, in addition to its shape and texture, its apparent movement is similar to that of a real one. Among such toy guns, the one simulating a gun in which a slider arranged along a barrel is moved in response to an operation of a trigger, and is loaded in a loading chamber provided at a rear end portion of the barrel. 2. Description of the Related Art In addition to the fact that bullets are fired by gas pressure, there is known a type in which bullets are supplied to a loading chamber by using gas pressure. For example,
As shown in Japanese Patent Publication No. 593, a pressure storage cylinder, a magazine, first and second valves, first and second valves provided with a gas discharge passage which is filled with air and controlled to be opened and closed by an on-off valve. A gas passage, and a bullet supply lever are arranged on the grip portion, and a cylinder opposed to the barrel via a magazine plate forming an impact hole is provided in a slider arranged on the barrel provided with an impact hole. A rotating cam that engages with the magazine plate and selectively lifts and lowers the magazine plate, and a spring guide member that is moved with the movement of the slider, and uses the pressure of air from the pressure storage cylinder. In addition, there has been proposed a toy gun adapted to fire a bullet loaded in the impact hole and supply the bullet to the impact hole.

[0003] In such a toy gun, when the trigger is pulled, the first valve causes air from the accumulator cylinder whose gas outlet passage is opened by the on-off valve to enter the cylinder through the first gas passage. In the state to be supplied, the pressure of the air supplied to the cylinder causes the piston member housed in the cylinder to retract the slider from the initial position. The cylinder to which the air from the accumulator is supplied is exhausted when the slider is retracted by a predetermined amount. On the other hand, as the slider retreats from the initial position, the spring guide member is retracted while compressing the spring member, and rotates the rotary cam in a direction to lower the magazine plate engaged with it.
As a result, the impact hole in the magazine plate is moved from the initial position facing the muzzle to a position facing the bullet discharged from the magazine. Then, the bullet discharged from the magazine is loaded into the impact hole by the bullet supply lever which is swung in conjunction with the trigger.

[0004] Under such circumstances, when the cylinder is put in the exhaust state and the slider advances from the retreat position to reach the initial position, the spring member is returned to the original position by returning the spring guide member to the original position, As a result, the rotating cam is rotated in the direction for raising the magazine plate, and the impact hole loaded with the bullet is set at the initial position. When the impact hole in which the bullet is loaded is placed at the initial position, the second valve causes the second valve to move from the accumulator cylinder in which the gas outlet passage is opened by the on-off valve when the hammer rotates in conjunction with the trigger. In a state where air is supplied to the impact hole through the second gas passage, the pressure of the air supplied to the impact hole causes the bullet loaded in the impact hole to move the bullet forward from the retreat position. Fired upon reaching the initial position.

[0005]

As described above, a cylinder forming a pressure chamber is arranged in a slider movably provided with respect to a barrel, and air is supplied to the pressure chamber by a trigger being pulled. In a conventionally proposed toy gun in which a bullet is supplied to a landing hole by discharging, automatic firing of the bullet is enabled.

Therefore, there is a problem that it is not easy to secure a space for disposing the gas control means in the toy gun body. Moreover, each of the first and second valves constituting the gas control means substantially controls the pressure of the air supplied from the accumulator into the common gas passage, and is disposed adjacent to each other. Thus, there is also an inconvenience that the restrictions imposed on the arrangement of the first and second valves are made relatively strict, and the degree of freedom in design is reduced.

In view of the above, the invention described in the claims of the present application provides a bullet chamber in which a bullet fired by utilizing gas pressure from a pressure accumulating chamber is loaded at a rear end portion of a barrel portion. In addition to being provided, a slider portion is provided which is retracted along the barrel portion by using gas pressure from the accumulator and prepares to supply the next bullet to the loading chamber after the bullet is fired. Gas control means configured to include a valve means provided in a gas circulation space formed in association with a pressure accumulation chamber having a gas discharge passage portion, and to control gas discharged from the pressure accumulation chamber through the gas discharge passage portion.

Are connected to the other ends of the first internal space 23 and the second internal space 24, respectively.

As described above, when the trigger 1 is pulled with the bullet BB loaded in the loading chamber 4 as shown in FIG. 1, the movable bar 11 retreats accordingly. As a result, as shown in FIG. 7, the movable contact member 16 which takes the upper position and contacts the rear end of the movable bar 11 performs the movement of pressing the lower portion 15A of the rotating lever 15 backward. Then, the rotation lever 15 is rotated against the urging force of the engagement piece 38A of the leaf spring member 38. As a result, the mutual engagement between the distal end portion of the rotating lever 15 and the lower portion of the first hammer 6 is released.

The first hammer 6 released from the state in which the position is regulated by the rotating lever 15 has a state in which the locking portion 7A of the second hammer 7 is in contact with the lower side thereof, and It rotates in the direction a according to the urging force. Then, the first hammer 6 that rotates in the direction a.
Rotates the second hammer 7 in the direction a via the locking portion 7A. As a result, the rotating arm 36 attached to the second hammer 7 is attached to the rod 51 provided on the opening / closing valve portion 45 at substantially the same time as the time when the trigger 1 contacts the contact portion 12. Coil spring 5
2 is pressed while being compressed.

When the rod 51 is pressed, the on-off valve portion 45 is moved from the position where the gas outlet passage portion 44 is closed to the position where the gas outlet passage portion 44 is opened, and the gas outlet passage is opened. The part 44 is opened. Due to the rotation of the second hammer 7 in such a case, the lock member 31 is located at a position where it engages with the engaging portion 34 provided on the toy gun body 10. Thereby, the second hammer 7
However, the rotation in the direction according to the biasing force of the toggle spring 30 shown in FIG. 3 is restricted, and the opening / closing valve portion 45 is maintained at the position where the gas outlet passage portion 44 is opened. In addition, the second hammer 7 whose rotation in the direction following the biasing force of the toggle spring 30 is restricted as described above causes the first hammer 6 to move to its position under the release of the position restriction by the rotation lever 15. Is fixed.

The gas from the pressure accumulating chamber 43 through the opened gas outlet passage portion 44 immediately flows into the passage connecting portion 47. At this time, the movable valve portion 46 housed in the valve housing space 48 of the passage connecting portion 47 is
Since both the first passage portion 49A and the second passage portion 49B are open, the gas flowing into the passage connecting portion 47 flows through the valve housing space 48 in the passage connecting portion 47.
And the first passage portion 49A and the second passage portion 49B are filled, and further, the bullet BB loaded into the ammunition chamber 4 from the first passage portion 49A through the first internal space 23 of the movable member 20. And the second passage 49B
Then, the pressure reaches the pressure receiving portion 61A through the second internal space 24 in the movable member 20.

At this time, the bullet BB loaded in the loading chamber 4
Is required to be pushed forward from the loading chamber 4 into the inner barrel 2I by the gas required to move the pressure receiving portion 61A rearward with the bottomed tubular portion 61 and the slider portion 60. The pressure is smaller than the pressure. Therefore,
The gas acting on the bullets BB loaded in the loading chamber 4 without the pressure receiving portion 61A moving backward with the bottomed cylindrical portion 61 and the slider portion 60 due to the gas pressure acting on the pressure receiving portion 61A. As a result of the pressure, the bullet BB loaded in the loading chamber 4 is pushed forward from the loading chamber 4 into the inner barrel 2I as shown by a dashed line in FIG. The gas is accelerated in the inner barrel 2I by the gas flowing into the inner barrel 2I from 23 and advances, and is fired from the tip of the inner barrel 2I as shown in FIG.

When the bullet BB is fired from the inner barrel 2I, the gas flowing from the first internal space 23 of the movable member 20 into the inner barrel 2I is released from the tip of the inner barrel 2I to the atmosphere. The gas pressure in the inner barrel 2I, in the first internal space 23 of the movable member 20, and further in the first passage portion 49A of the passage connecting portion 47 connected to the first internal space 23, suddenly decreases. I do. The first in such a passage connecting portion 47
The sudden decrease in the gas pressure in the passage 49A is caused by the movable valve 46 disposed in the valve housing space 48 in the passage connecting portion 47.
The movable valve portion 46 is moved toward the first passage portion 49A against the urging force of the coil spring 50, and the movable valve portion 46 is moved toward the first passage portion 49A. The large-diameter portion 46B of the portion 46 abuts on a portion forming one end of the first passage portion 49A of the passage connecting portion 47, and the first passage portion 49A is in a cutoff state. Thereby, the movable valve portion 46 allows the gas passing through the gas outlet passage portion 44 to pass through the first passage portion 4 in the passage connecting portion 47.
The flow toward the loading chamber 4 is prevented through the first internal space 23 in the movable member 9A and the movable member 20.

In this manner, the movable valve 46 causes the first passage portion 49A of the gas passage connecting portion 47 through the gas outlet passage portion 44 and the first internal space 23 of the movable member 20 to enter the loading chamber 4 through the movable passage portion 46. When the heading flow is blocked, the gas that has flowed into the valve housing space 48 in the passage connecting portion 47 from the pressure accumulation chamber 43 through the gas outlet passage portion 44 is
The second passage portion 49B of the passage connecting portion 47 does not flow into the first passage portion 49A of the passage connecting portion 47.
Then, the gas flows toward the pressure receiving portion 61A through the second internal space 24 of the movable member 20, and the gas pressure acting on the pressure receiving portion 61A rapidly increases. Thereby, as shown in FIG. 9, due to the increased gas pressure, the pressure receiving portion 61A
In the bottomed cylindrical portion 61, the variable volume pressure chamber formed between the movable member 20 and the end surface of the rear side portion is rapidly moved backward while increasing the variable volume pressure chamber.
The slider portion 60 is quickly retracted against the urging force of the coil spring 17. At this time, the first hammer 6 is rotated in the direction b by the rear end of the bottomed cylindrical portion 61 that retreats against the urging force of the coil spring 26.

Thereby, the movable contact member 16 contacting the rear end of the movable bar 11 is moved as shown in FIG.
The engagement portion 38B of the leaf spring member 38 is released by the retracted slider portion 60 while being released from the state where the position is regulated by the concave portion 60D provided on the bottom surface portion of the slider portion 60.
Is pressed in a direction against the urging force, and assumes a lower position. As a result, the mutual contact state between the movable contact member 16 and the lower portion 15A of the rotating lever 15 is released, and the rotating lever 15 rotates in a direction according to the urging force of the engagement piece 38A of the leaf spring member 38. It will move. Further, the lock member 31 disposed on the second hammer 7 is
0, the slider portion 6 as shown in FIG.
0 is pressed downward against the urging force of the coil spring 32 by the protrusion 60C provided on the bottom surface of the toy gun 10 and released from the mutual engagement state with the engagement portion 34 provided on the toy gun body 10. Thereby, the second hammer 7 is released from the position restricted state, and the toggle spring 30 is released.
(FIG. 3).

The turning lever 15 which turns by the urging force of the engaging piece 38A of the leaf spring member 38 engages with the lower part of the first hammer 6, whereby the turning lever 15 and the first Hammer 6 is placed in the mutual position regulation state. In addition, the second rotating by the biasing force of the toggle spring 30
Of the hammer 7, the concave portion 7B of which is in contact with the shaft 14, is fixed in position.

In this case, the rotation of the second hammer 7 according to the biasing force of the toggle spring 30 causes the opening / closing valve portion 45 to be fixed in position by the rotating arm 36 abutting on the rear end of the rod 51 provided thereon. You are released from the state where was done. The opening / closing valve portion 45 released from the fixed position by the rotating arm 36 closes the gas outlet passage portion 44 by the gas pressure acting on the valve portion 45 and the urging force of the coil spring 52 as shown in FIG. Take a position to do.

Accordingly, under such circumstances, the passage connecting portion 4

A coil spring 80 is mounted on the shaft portion 76B of the movable valve portion 76.
When the slider portion 60 is at the reference position, the entirety of the movable valve portion 76 is set to the first position in the middle portion of the movable member 70 which takes a position corresponding to the reference position of the slider portion 60.
Is biased in a direction to separate the large-diameter head 76A from the lower opening end, which is the other end of the internal space 73. As a result, the movable valve portion 76 is moved in the valve housing space 78 in a steady state, as shown in FIG.
The position is regulated so that the first internal space 73 of the movable member 70 at the position corresponding to the reference position is opened.

The movable valve portion 76 housed in the valve housing space 78 moves in the direction of compressing the coil spring 80 against the urging force of the coil spring 80 under a predetermined state described later. When the slider portion 60 is at the reference position, the large-diameter head portion 76A is positioned at the other end of the first internal space 73 at an intermediate portion of the movable member 70 which takes a position corresponding to the reference position of the slider portion 60. An operation of bringing the first internal space 73 of the movable member 70 into a closed state by the large-diameter head 76A is performed by bringing the first inner space 73 into contact with the valve receiving portion 73A formed at a certain lower opening end. The second internal space 74 of the movable member 70 is always open regardless of the movement of the movable valve portion 76.

Also in the example shown in FIG. 12 configured as described above, the slider portion 60 is temporarily retracted by a manual operation and is released from the retreat operation, so that the bullet BB is added to the bullet chamber 4.

At this time, since the movable valve portion 76 accommodated in the valve accommodation space 78 of the passage connecting portion 77 opens the first internal space 73 of the movable member 70,
Both the first internal space 73 and the second internal space 74 of the movable member 70 are open. Therefore, the gas flowing into the passage connecting portion 77 fills the valve housing space 78 in the passage connecting portion 77 and further passes through the first internal space 73 in the movable member 70 to the bullet BB loaded in the bullet chamber 4. At the same time, it reaches the pressure receiving portion 61A through the second internal space 74 of the movable member 70.

At this time, the bullet BB loaded in the loading chamber 4
Is required to be pushed forward from the loading chamber 4 into the inner barrel 2I by the gas required to move the pressure receiving portion 61A rearward with the bottomed tubular portion 61 and the slider portion 60. The pressure is smaller than the pressure. Therefore,
The gas acting on the bullet BB loaded in the loading chamber 4 is maintained without the pressure receiving portion 61A moving backward with the bottomed cylindrical portion 61 and the slider portion 60 due to the gas pressure acting on the pressure receiving portion 61A. Due to the pressure, the bullet BB loaded in the loading chamber 4 is pushed forward from the loading chamber 4 into the inner barrel 2I, and flows from the first internal space 73 in the movable member 70 into the inner barrel 2I. As a result, it is accelerated and advances in the inner barrel 2I, and is fired from the tip of the inner barrel 2I.

When the bullet BB is fired from the inner barrel 2I, the gas flowing into the inner barrel 2I from the first internal space 73 of the movable member 70 is released into the atmosphere from the tip of the inner barrel 2I. The gas pressure in the inner barrel 2I and in the first internal space 73 of the movable member 70 suddenly decreases. Such a sharp decrease in the gas pressure in the first internal space 73 of the movable member 70 causes the movable valve portion 76 disposed in the valve accommodation space 78 of the passage connecting portion 77 to move the gas to the first valve portion of the movable member 70. Acting as a negative pressure drawn into the internal space 73 side, the movable valve portion 76 is moved toward the first internal space 73 in the movable member 70 against the urging force of the coil spring 80, and the movable valve portion 76 The large-diameter head 76A abuts on a valve receiving portion 73A formed at a lower opening end that is the other end of the first internal space 73 in the intermediate portion of the movable member 70, and the first inner portion of the movable member 70 The space 73 is closed. Thus, the flow of the gas through the gas outlet passage portion 44 toward the loading chamber 4 through the first internal space 73 of the movable member 70 is prevented by the movable valve portion 76.

As described above, when the flow of the gas flowing through the gas outlet passage 44 toward the loading chamber 4 through the first internal space 73 in the movable member 70 is stopped by the movable valve portion 76, The gas that has flowed into the valve housing space 78 in the passage connecting portion 77 through the gas outlet passage portion 44 does not flow into the first internal space 73 in the movable member 70, but the second internal space 7 in the movable member 70.
4 to the pressure receiving portion 61A,
The gas pressure acting on 1A sharply increases. Thereby,
The increased gas pressure causes the pressure receiving portion 61A to move quickly backward while increasing the variable volume pressure chamber formed between the movable member 70 and the end surface of the rear portion in the bottomed cylindrical portion 61. Accordingly, the slider portion 60 is quickly retracted against the urging force of the coil spring 17.

The subsequent operation proceeds in the same manner as the operation in the example shown in FIG.
The slider 70 is retracted to the rearmost position of 0 and the slider 60 is retracted, and further, the slider 60 is returned to the reference position by advancing the slider 60 with the movable member 70. The chamber 4 is loaded with a new bullet BB.

Under these circumstances, the movable valve portion 76 disposed in the valve accommodating space 78 in the passage connecting portion 77 has the slider portion 60 at the reference position and the movable member 70 at the reference position of the slider portion 60. The gas outlet passage 44 extending from the pressure accumulating chamber 43 at the corresponding position is opened and closed while being connected to the first and second internal spaces 73 and 74 of the movable member 70 through the valve housing space 78 of the passage connecting portion 77. During the period in which the valve portion 45 opens the gas outlet passage portion 44, the first internal space 73 of the movable member 70 is opened, and the gas passing through the gas outlet passage portion 44 is passed through the valve housing space 78 in the passage connecting portion 77. From the first state of acting on the bullet BB supplied to the loading chamber 4 through the first internal space 73 of the movable member 70, By blocking the internal space 73, the gas flowing through the gas outlet passage portion 44 is prevented from flowing toward the loading chamber 4 through the valve housing space 78 in the passage connecting portion 77 and the first internal space 73 in the movable member 70. The gas passing through the gas outlet passage portion 44 is passed through the passage connecting portion 7.
7, the movable member 7
0 to the second state in which the pressure receiving section 61A is directed toward the pressure receiving section 61A through the second internal space 74, and the pressure receiving section 61A is moved backward with the slider section 60 by the gas pressure under the second state. become.

As a result of the operation of the movable valve portion 76, after the bullet BB is fired from the inner barrel 2I, the retreat of the slider portion 60 is started by the gas pressure acting on the pressure receiving portion 61A which is rapidly increased. So
When the bullet BB is fired, the effect of the movement of the slider portion 60 on the barrel portion 2 is avoided. Accordingly, it is possible to prevent the direction of the bullet BB fired from the inner barrel 2I from being out of order.
