2. Description of the Related Art In a toy gun called a play gun (airsoft gun), in addition to the color and the shape, the apparent movement is usually made to be similar to the real thing. Among such toy guns, a model imitating a gun in which a slider provided in relation to the barrel moves in response to the operation of a trigger is loaded in a loading chamber provided in a rear end portion of the barrel. It is known that, in addition to the firing of bullets by gas pressure, the supply of bullets to the loading chamber is also performed by using gas pressure. For example, Actual Kaihei 3-
As shown in Japanese Patent No. 38593, a pressure accumulator cylinder, a magazine, a first and a second valve, a first valve, which are filled with air and provided with a gas outlet passage part whose opening / closing is controlled by an opening / closing valve.
And the second gas passage and the bullet feed lever are disposed in the grip portion, and the barrel is provided in the slider provided for the barrel provided with the impact hole, through the magazine plate forming the impact hole. An opposing cylinder and a spring guide member that moves with the movement of the slider are arranged, and the pressure of the air from the accumulator cylinder is used to fire the bullet loaded in the impact hole and supply the bullet to the impact hole. A toy gun designed to do this has been proposed.

In such a toy gun, when the trigger is pulled, the first valve opens the first gas passage, and the air from the pressure accumulating cylinder passes through the first gas passage. The piston member housed in the cylinder retracts the slider from the initial position by the pressure of the air supplied into the cylinder and supplied into the cylinder. Then, the cylinder to which air is supplied from the pressure accumulating cylinder is placed in an exhaust state 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, whereby the impact hole in the magazine plate is ejected from the magazine from the initial position facing the muzzle. Is moved to the position opposite to. Then, the bullets ejected from the magazine are loaded into the impact holes by a bullet feed lever that is swung in conjunction with a trigger. Under such circumstances, when the cylinder is in the exhaust state and the slider advances from the retracted position to reach the initial position, the spring member is returned to the original position to return the spring guide member to the original position. , The bullet loading hole is placed in the initial position.

When the impact hole loaded with bullets is placed in the initial position, the second valve opens the second gas passage by the hammer (hammering iron) that rotates in conjunction with the trigger. In this state, the air from the pressure accumulating cylinder is supplied to the impact hole through the second gas passage, and the pressure of the air supplied to the impact hole causes the bullet loaded in the impact hole to advance from the retracted position. Fired when the slider reaches the initial position.

In this way, 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 retracts accordingly. As a result, the movable contact member 16 which comes into contact with the rear end portion of the movable bar 11 at the upper position is moved to press the lower portion 15A of the rotating lever 15 backward, as shown in FIG. , The rotating lever 15 is rotated against the biasing force of the engaging piece portion 38A of the leaf spring member 38. As a result, the mutual engagement state between the tip end portion of the rotating lever 15 and the lower side portion of the first hammer 6 is released.

The first hammer 6 released from the position regulated by the turning lever 15 has a state in which the engaging portion 7A of the second hammer 7 is in contact with the lower portion of the first hammer 6, and the coil spring 26 It rotates in the a direction according to the biasing force. Then, the first hammer 6 that rotates in the a direction
Rotates the second hammer 7 in the a direction via the locking portion 7A. As a result, the rod 51 provided in the gas passage opening / closing part 45 is attached to the pivot arm 36 attached to the second hammer 7 at substantially the same time as the trigger 1 contacts the contact part 12. The coil spring 52 thus pressed is pressed while being compressed.

When the rod 51 is pushed, the gas passage opening / closing portion 45 is pushed and 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 passage opening / closing portion 45 is closed. The lead-out passage portion 44 is opened. By the rotation of the second hammer 7 in such a case,
The lock member 31 is placed at a position where it engages with the engaging portion 34 provided on the toy gun body 10. As a result, the second hammer 7 is restricted from rotating in the direction according to the biasing force of the toggle spring 30 shown in FIG.
5 maintains the position where the gas lead-out passage portion 44 is in the open state. Further, the second hammer 7 whose rotation in the direction according to the biasing force of the toggle spring 30 is restricted in this way causes the first hammer 6 to move its position under the condition that the rotation lever 15 releases the position restriction. Is fixed.

The gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 which has been opened is immediately flown into the passage connecting portion 47. At this time, the movable valve portion 46 accommodated in the valve accommodating space 48 of the passage connecting portion 47 is biased by the coil spring 50, and the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 is moved in the movable member 20. Since the flow toward the shot-loading chamber 4 can be generated through the first internal space 23 and both the first passage portion 49A and the second passage portion 49B in the passage connecting portion 47 are opened, the passage connecting portion The gas flowing into the portion 47 is supplied to the valve housing space 48 and the first passage portion 49A in the passage connecting portion 47.
And the second passage portion 49B, and further, the first inner space 2 in the first passage portion 49A and the movable member 20.
Flow toward the shot-loading chamber 4 through 3 to cause gas pressure to act on the bullet BB in the shot-loading chamber 4, and flow toward the pressure-receiving portion 61A through the second passage 49B and the second internal space 24 in the movable member 20. Also occurs and the pressure receiving portion 61
A gas pressure is applied to A.

At this time, the gas pressure required to push the bullet BB in the loading chamber 4 forward from the loading chamber 4 into the inner barrel 2I is such that the pressure receiving portion 61A has the bottomed tubular portion 61 and the slider portion 60. Is smaller than the gas pressure required to move it backwards. Therefore, the pressure receiving portion 6
By the gas pressure acting on the bullet BB loaded in the loading chamber 4 without the state where the pressure receiving portion 61A moves rearward together with the bottomed tubular portion 61 and the slider portion 60 due to the gas pressure acting on 1A, , The bullet BB in the loading chamber 4 is shown in FIG.
In the inner barrel 2I, the gas pushed forward from the loading chamber 4 into the inner barrel 2I and flowing into the inner barrel 2I from the first inner space 23 in the movable member 20 as indicated by the alternate long and short dash line in FIG. In Fig. 7, it is accelerated and advances, and as shown in Fig. 7, it is projected from the tip of the inner barrel 2I and is fired. In this way, the gas from the pressure accumulating chamber 43 causes the bullet BB in the loading chamber 4 to fire.

When the bullet BB jumps out from the tip of the inner barrel 2I, the first internal space 23 in the movable member 20 is removed.
The gas flowing into the inner barrel 2I from the inside is discharged from the tip of the inner barrel 2I to the atmosphere, whereby
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 inner space 23 rapidly decreases. . The sudden decrease in the gas pressure in the first passage portion 49A of the passage connecting portion 47 causes the movable valve portion 4 arranged in the valve accommodating space 48 of the passage connecting portion 47.
6, it acts as a negative pressure to draw it toward the first passage portion 49A side, and the movable valve portion 46 is moved toward the first passage portion 49A against the urging force of the coil spring 50 to move. The large diameter portion 46B of the valve portion 46 contacts one end of the first passage portion 49A to bring the first passage portion 49A into the closed state. As a result, the movable valve portion 46 blocks the flow of the gas through the gas outlet passage portion 44 toward the impact chamber 4 through the first passage portion 49A in the passage connecting portion 47 and the first internal space 23 in the movable member 20. Will be done.

In this manner, the movable valve portion 46 allows the gas from the pressure accumulating chamber 43 to pass through the gas outlet passage portion 44, the first passage portion 49A of the passage connecting portion 47 and the first internal space of the movable member 20. When the flow toward the shot-loading chamber 4 is blocked through 23, the valve accommodating space 48 in the passage connecting portion 47 from the pressure accumulating chamber 43 through the gas outlet passage portion 44.
The gas that has flowed into the passage connecting portion 47 does not flow into the first passage portion 49A in the passage connecting portion 47, but reaches the pressure receiving portion 61A through the second passage portion 49B in the passage connecting portion 47 and the second internal space 24 in the movable member 20. I will be heading.
Therefore, at this time, the movable valve portion 46 is connected to the passage connecting portion 47.
In response to a sudden decrease in gas pressure in the first passage portion 49A
Then, a flow of gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 toward the impact chamber 4 through the first passage portion 49A in the passage connecting portion 47 and the first internal space 23 in the movable member 20 is generated. The first passage portion 49A of the passage connecting portion 47 and the first portion of the movable member 20 of the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 from the state in which the gas pressure is applied to the bullet BB in the loading chamber 4 Block the flow toward the shot chamber 4 through the internal space 23 of the
Of the gas from the pressure accumulating chamber 43 through the gas outlet passage 44,
The pressure receiving portion 61 passes through the second passage portion 49B of the passage connecting portion 47 and the second internal space 24 of the movable member 20.
A flow toward A is generated, and the state is changed to a state in which the gas pressure acts on the pressure receiving portion 61A.

The gas flowing into the valve accommodating space 48 does not flow into the first passage portion 49A of the passage connecting portion 47, and the second passage portion 49B of the passage connecting portion 47 and the first passage portion 49B of the movable member 20 do not flow. The flow toward the pressure receiving portion 61A is generated through the internal space 24 of the second pressure receiving portion 61A.
The gas pressure acting on the pressure receiving portion 61A rapidly increases by acting the gas pressure on the. As a result, as shown in FIG. 8, due to the increased gas pressure, the pressure receiving portion 61A is
The variable volume pressure chamber formed between the end surface portion of the rear side portion of the movable member 20 in the bottomed tubular portion 61 is rapidly moved rearward while increasing the variable volume pressure chamber.
The slider portion 60 is rapidly retracted against the biasing force of the coil spring 17. That is, the gas from the pressure accumulating chamber 43 causes the slider portion 60 to retract. At that time, the rear end portion of the bottomed tubular portion 61 that retracts causes the first hammer 6 to resist the urging force of the coil spring 26 by b.
It can be rotated in the direction.

After that, as shown in FIG. 9, through the second passage portion 49B in the passage connecting portion 47 and the second internal space 24 in the movable member 20, the pressure receiving portion 61A and the movable member in the bottomed tubular portion 61 are passed. The gas flowing into the variable volume pressure chamber formed between the end surface portion of the rear side portion of 20 and the end surface portion of the portion 20 continues the backward movement of the pressure receiving portion 61A together with the slider portion 60. As a result, the movable contact member 16 that contacts the rear end of the movable bar 11 is released from the state in which the position is restricted by the recess 60D provided in the bottom surface portion of the slider portion 60 as shown in FIG. At the same time, the retracted slider portion 60 pushes the slider spring member 38 in the direction against the urging force of the engaging piece portion 38B of the leaf spring member 38 to take the lower position. As a result, the movable contact member 16 and the rotating lever 1

Then, the bullet BB is loaded in the loading chamber 4, and the passage connecting portion 77 allows the gas outlet passage portion 44 to pass through the valve accommodating space 78 through the first internal space 73 and the second internal space 74 of the movable member 70. And the movable valve portion 76 is urged by the coil spring 80 to allow the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 to pass through the passage connecting portion 77 and the movable member 70. When the trigger 1 is pulled in a state in which the flow toward the shot-loading chamber 4 through the internal space 73 of No. 1 is generated, the rotary arm 36 attached to the second hammer 7 causes the gas passage opening / closing unit 45 to move. The coil spring 52 attached to the rod 51 is pressed against the rod 51 while being compressed, so that the gas passage opening / closing portion 45 closes the gas outlet passage portion 44 from the gas outlet passage. The part 44 is moved to a position to the open state, it is the gas leading passage 44 is opened.
Then, the second hammer 7 causes the gas passage opening / closing portion 45 to maintain the position where the gas outlet passage portion 44 is in the open state.

The gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 which is opened is immediately flown into the passage connecting portion 77. At this time, the movable valve portion 76 accommodated in the valve accommodating space 78 in the passage connecting portion 77 opens the first internal space 73 in the movable member 70, and the movable valve portion 76 is removed from the pressure accumulating chamber 43 through the gas outlet passage portion 44. Since the gas can flow through the passage connecting portion 77 and the first internal space 73 of the movable member 70 toward the impact chamber 4, the first internal space 73 and the second internal space of the movable member 70 can be generated. Both 74 are open. Therefore, the gas flowing into the passage connecting portion 77 is
7, the valve housing space 78 in the movable member 70 is filled, and further, a flow is generated toward the shot chamber 4 through the first internal space 73 in the movable member 70, causing gas pressure to act on the bullet BB in the shot chamber 4 and the movable member 70. A flow toward the pressure receiving portion 61A is generated through the second internal space 74, and a gas pressure acts on the pressure receiving portion 61A.

At this time, the gas pressure required for the bullet BB in the loading chamber 4 to be pushed forward from the loading chamber 4 into the inner barrel 2I is such that the pressure receiving portion 61A has the bottomed tubular portion 61 and the slider portion 60. Is smaller than the gas pressure required to move it backwards. Therefore, the pressure receiving portion 6
The gas pressure acting on 1A does not cause the pressure receiving portion 61A to move rearward along with the bottomed tubular portion 61 and the slider portion 60, and the gas pressure acting on the bullet BB in the bullet chamber 4 allows The bullets BB in the chamber 4 are pushed forward from the loading chamber 4 into the inner barrel 2I, and the gas flowing from the first internal space 73 in the movable member 70 into the inner barrel 2I causes the bullets BB in the inner barrel 2I. It is accelerated, moves forward, is projected from the tip of the inner barrel 2I, and is fired. In this way, the gas from the accumulator chamber 43 will cause the bullets in the bombardment chamber 4 to fire.

When the bullet BB jumps out of 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 from the tip of the inner barrel 2I to the atmosphere, whereby the inner barrel 2I is released. The gas pressure in the barrel 2I and the first internal space 73 in the movable member 70 is rapidly reduced. Such a movable member 7
The sudden decrease of the gas pressure in the first internal space 73 at 0 causes the movable valve portion 76 disposed in the valve accommodating space 78 in the passage connecting portion 77 to move the movable valve portion 76 to the first internal space 73 side of the movable member 70. It acts as a negative pressure to draw in the movable valve part 7
6 is moved toward the first internal space 73 in the movable member 70 against the biasing force of the coil spring 80, and the large-diameter head portion 76A of the movable valve portion 76 is moved to the first portion in the intermediate portion of the movable member 70. The first internal space 73 of the movable member 70 is brought into a closed state by contacting the valve receiving portion 73A provided at the lower opening end formed by the other end of the first internal space 73. As a result, the movable valve portion 76 allows the gas passing through the gas discharge passage portion 44 to pass through the passage connecting portion 77 and the first internal space 73 in the movable member 70 through the loading chamber 4.
The flow toward it will be blocked.

In this way, the movable valve portion 76 blocks the flow of the gas through the gas outlet passage portion 44 toward the impact chamber 4 through the passage connecting portion 77 and the first internal space 73 in the movable member 70. And the gas flowing from the pressure accumulating chamber 43 into the valve housing space 78 in the passage connecting portion 77 through the gas outlet passage portion 44 is the first gas in the movable member 70.
Flow into the pressure receiving portion 61A through the second internal space 74 of the movable member 70 without flowing into the internal space 73 of the movable member 70, and the gas pressure acts on the pressure receiving portion 61A. The pressure increases rapidly. As a result, the increased gas pressure causes the pressure receiving portion 61 to
A rapidly moves rearward while increasing the variable volume pressure chamber formed between the end face portion of the rear side portion of the movable member 70 in the bottomed tubular portion 61, and accordingly, the slider portion. 60 is rapidly retracted against the urging force of the coil spring 17. That is, the gas from the pressure accumulating chamber 43 causes the slider portion 60 to retract.

The subsequent operation proceeds in the same manner as the operation in the example shown in FIG. 2 described above, and the slider portion 6
The movable member 70 is retracted to the rearmost position of 0 and the slider portion 60 is retracted, and then the slider portion 60 is moved forward with the movable member 70 to return to the reference position. The chamber 4 is loaded with a new bullet BB.

Under such a condition, in the movable valve portion 76 arranged in the valve accommodating space 78 in the passage connecting portion 77, the slider portion 60 is at the reference position and the movable member 70 is at the reference position of the slider portion 60. The gas outlet passage portion 44 extending from the pressure accumulating chamber 43 at the corresponding position is connected to the first and second internal spaces 73 and 74 of the movable member 70 through the valve accommodating space 78 of the passage connecting portion 77. During a period in which the passage opening / closing portion 45 opens the gas outlet passage portion 44, the gas pressure in the passage connecting portion 77 is drastically reduced.
Depending on the bottom, the first internal space 73 in the movable member 70 is opened, and the gas passing through the gas outlet passage 44 is
A flow is generated toward the impact chamber 4 through the valve accommodating space 78 in the passage connecting portion 77 and further through the first internal space 73 of the movable member 70, and gas pressure is applied to the bullet BB in the impact chamber 4. From this state, the first internal space 73 in the movable member 70 is shut off, and the gas passing through the gas outlet passage 44 is accommodated in the valve accommodation space 78 in the passage connecting portion 77 and the first internal space 7 in the movable member 70.
3, the flow toward the shot-loading chamber 4 is blocked, and the gas passing through the gas outlet passage portion 44 passes through the valve accommodating space 78 in the passage connecting portion 77 and further through the second internal space 74 of the movable member 70. To a second state in which a gas pressure acts on the pressure receiving portion 61A, and under the second state, the gas pressure causes the pressure receiving portion 61A to move.
A will be moved rearward along with the slider portion 60.

As a result of the operation of the movable valve portion 76, the backward movement of the slider portion 60 is started by the gas pressure acting on the pressure receiving portion 61A which is sharply increased after the bullet BB is fired from the inner barrel 2I. So
It is possible to prevent the slider section 60 from affecting the barrel section 2 due to its movement when the bullet BB is fired. Therefore, deviation in the direction of the bullet BB fired from the inner barrel 2I is prevented.
