Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The invention described in the claims of the present application utilizes a gas pressure to fire a bullet fired by a gas pressure into a loading chamber provided at the rear end of a barrel (barrel). The present invention relates to a toy gun provided with an automatic bullet supply mechanism.

[0002]

2. Description of the Related Art In general, a toy gun called an airsoft gun is created so that not only its color and shape but also its apparent movement is similar to that of a real one. Among such toy guns, the one imitating a gun in which a slider provided in connection with a barrel is moved in response to an operation of a trigger is loaded into a loading chamber provided at a rear end portion of the barrel. It is known that, in addition to firing bullets by gas pressure, the supply of bullets to the loading chamber is also performed by using gas pressure. For example,
As shown in Japanese Patent No. 38593, a pressure storage cylinder, a magazine, a first and a second valve, a first and a second valve, each of which is filled with air and provided with a gas lead-out passage portion controlled to be opened and closed by an on-off valve.
And a second gas passage, and a bullet supply lever are disposed on the grip portion, and are provided in the barrel via a magazine plate forming a landing hole in a slider disposed on the barrel provided with a landing hole. An opposing cylinder and a spring guide member that is moved in accordance with the movement of the slider are arranged, and the pressure of air from the pressure storage cylinder is used to fire the bullet loaded in the impact hole and supply the bullet to the impact hole. A toy gun adapted to do so has been proposed.

[0003] In such a toy gun, when the trigger is pulled, the first valve places the first gas passage in an open state, and air from the accumulator cylinder passes through the first gas passage. The piston member accommodated in the cylinder retreats the slider from the initial position by the pressure of the air supplied to the cylinder and supplied to the cylinder. Then, the cylinder to which the air is supplied from such a pressure storage cylinder is exhausted when the slider is retracted by a predetermined amount. On the other hand, with the retraction of the slider from the initial position, the spring guide member is retracted while compressing the spring member, whereby the impact hole in the magazine plate is discharged from the magazine from the initial position facing the muzzle. Is moved to a position opposite to. Then, the bullet discharged from the magazine is loaded into the impact hole by the bullet feed lever which is swung in conjunction with the trigger. Under such circumstances, when the cylinder is placed in the exhaust state and the slider moves forward from the retracted position and reaches the initial position, the spring member is returned to the original position by returning the spring guide member to the original position. The landing hole loaded with the bullet is placed at the initial position.

[0004] When the impact hole loaded with the bullet is placed at the initial position, the second valve opens the second gas passage by the hammer (striking iron) that rotates in conjunction with the trigger. In this state, the air from the pressure storage cylinder is supplied to the impact hole through the second gas passage, and the bullet loaded in the impact hole moves forward from the retracted position by the pressure of the air supplied to the impact hole. Fired when the slider reaches the initial position.

[0005]

As described above, a cylinder forming a pressure chamber to which air from a pressure accumulating cylinder is supplied is disposed in a slider movably provided with respect to a barrel. The supply of bullets to the impact holes is performed by the sliders that are moved by the supply and discharge of air to the pressure chambers performed in response to the movement of the bullets supplied to the impact holes by the rotation of the hammer in conjunction with the operation on the trigger. In a toy gun that has been conventionally proposed as a toy gun in which firing is performed using air from a pressure storage cylinder, automatic firing of bullets is enabled. However, since the pressure accumulation cylinder is provided with the first and second valves in addition to the on-off valve, the connecting portion for maintaining the on-off valve at a position where the gas outlet passage portion is opened, A valve control mechanism for controlling the operation of the valve, and
The configuration of the gas control means for controlling the air derived from the pressure storage cylinder, which includes a hammer for controlling the operation of the second valve, becomes relatively large and complicated as a whole. Therefore, there is a problem that it is not easy to secure a space for disposing the gas control means in the toy gun main 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 is provided with a bullet chamber in which a bullet fired by gas pressure from a pressure accumulating chamber is provided at a rear end portion of a barrel portion. The gas pressure from the accumulator is used to retreat along the barrel, and after the bullet has been fired, the slider is provided to prepare for supplying the next bullet to the loading chamber. A toy gun with an automatic bullet supply mechanism that can reliably control the gas that is discharged from the chamber through the gas discharge passage to cause the firing of the bullet and the retreat of the slider portion with a relatively small and simplified configuration. I will provide a.

It is conveyed to the loading chamber 4 along 0A. At the same time, the movable member 20 closes the uppermost end portion 41A of the magazine 41 again by the intermediate portion, and the front portion thereof is closed by the annular member 4A.
And the position is fixed. As a result, as shown in FIG.
A bullet BB is loaded in the loading chamber 4.

When the slider portion 60, which has been advanced to supply the bullet BB to the loading chamber 4, returns to the reference position, the first internal space 23 of the movable member 20 is returned again.
Is connected to the loading chamber 4 and the second internal space 2
The gas outlet passage portion 44 extending from the pressure accumulating chamber 43 is connected to the valve housing space 48 of the passage connecting portion 47 and the first passage portion 4 with one end of the first passage portion 4 being close to and facing the pressure receiving portion 61A.
9A and the second passage 49B, the movable member 20
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 while the bullet BB is loaded in the loading chamber 4 as shown in FIG. 1, the movable bar 11 retreats accordingly. As a result, as shown in FIG. 6, the movable contact member 16 which takes the upper position and abuts on 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 abuts on the lower side thereof, and the coil spring 26 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 attaches the rod 51 provided on the gas passage opening / closing section 45 to the trigger at about the same time as the time when the trigger 1 contacts the contact section 12. The compressed coil spring 52 is pressed while being compressed.

When the rod 51 is pressed, the gas passage opening / closing portion 45 is pressed and moved from a position where the gas outlet passage portion 44 is closed to a position where the gas outlet passage portion 44 is opened. The lead-out passage portion 44 is in an open state. 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 rotation of the second hammer 7 in the direction according to the biasing force of the toggle spring 30 shown in FIG.
5 to maintain the position where the gas outlet passage portion 44 is opened. Further, 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 accommodated in the valve accommodating space 48 in the passage connecting portion 47 is urged by the coil spring 50 so that the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 in the movable member 20. Since the flow toward the loading chamber 4 can be generated through the first internal space 23 and both the first passage 49A and the second passage 49B in the passage connecting portion 47 are in the open state, the passage connection is established. The gas flowing into the portion 47 is supplied to the valve housing space 48 in the passage connecting portion 47 and the first passage portion 49A.
And the second passage portion 49B, and further, the first internal space 2 in the first passage portion 49A and the movable member 20.
3, a gas flow is applied to the bullet BB in the loading chamber 4, and a gas pressure is applied to the bullet BB in the loading chamber 4. And the pressure receiving portion 61
Apply gas pressure to A.

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 determined by the pressure receiving portion 61A having the bottomed cylindrical portion 61 and the slider portion 60. Is smaller than the gas pressure required to be moved rearward. Therefore, the pressure receiving section 6
Due to the gas pressure acting on the bullet BB loaded in the loading chamber 4, the pressure receiving portion 61A does not move backward with the bottomed cylindrical 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.
As shown by a dashed line in FIG. 3, the gas that is pushed forward from the loading chamber 4 into the inner barrel 2I and flows from the first internal space 23 in the movable member 20 into the inner barrel 2I causes the gas in the inner barrel 2I. Then, the vehicle is accelerated and moves forward, and as shown in FIG. 7, is projected from the tip of the inner barrel 2I and fired. In this way, the gas from the pressure accumulating chamber 43 causes the firing of the bullet BB in the loading chamber 4.

When the bullet BB protrudes from the tip of the inner barrel 2I, the first internal space 23 in the movable member 20
The gas flowing into the inner barrel 2I from is released into the atmosphere from the tip of the inner barrel 2I,
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 rapidly decreases. . The sudden decrease in the gas pressure in the first passage portion 49A in the passage connection portion 47 is caused by the movable valve portion 4 disposed in the valve housing space 48 in the passage connection portion 47.
6 acts as a negative pressure that draws it into 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, and The large-diameter portion 46B of the valve portion 46 abuts one end of the first passage portion 49A, thereby closing the first passage portion 49A. Accordingly, the flow of the gas through the gas outlet passage portion 44 toward the loading chamber 4 through the first passage portion 49A in the passage connection portion 47 and the first internal space 23 in the movable member 20 is prevented by the movable valve portion 46. Will be done.

In this way, the movable valve portion 46 allows the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 to pass through the first passage portion 49A in the passage connecting portion 47 and the first internal space in the movable member 20. When the flow toward the loading chamber 4 through the nozzle 23 is blocked, the valve housing space 48 in the passage connecting portion 47 from the pressure accumulating chamber 43 through the gas outlet passage portion 44.
Does not flow into the first passage portion 49A in the passage connection portion 47, and flows into the pressure receiving portion 61A through the second passage portion 49B in the passage connection portion 47 and the second internal space 24 in the movable member 20. I will head.
Therefore, at this time, the movable valve portion 46 is
The gas from the pressure accumulating chamber 43 through the first passage portion 4 flows through the first passage portion 49A in the passage connecting portion 47 and the first internal space 23 in the movable member 20 toward the loading chamber 4, and the bullet in the loading chamber 4 is generated. From the state in which the gas pressure is applied to the BB, the gas from the pressure accumulating chamber 43 through the gas outlet passage 44 is transferred through the first passage 49A in the passage connecting portion 47 and the first internal space 23 in the movable member 20 to the loading chamber. 4 is blocked, and the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 receives 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. And a transition is made to a state in which 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 in the passage connection portion 47, and the second passage portion 49B in the passage connection portion 47 and the gas in the movable member 20 do not flow. 2 flows through the internal space 24 toward the pressure receiving portion 61A, and the pressure receiving portion 61A
, The gas pressure acting on the pressure receiving portion 61A rapidly increases. Thereby, as shown in FIG. 8, the pressure receiving part 61A is
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. That is, the gas from the pressure accumulating chamber 43 causes the slider portion 60 to retreat. At this time, the first hammer 6 is pressed against the biasing force of the coil spring 26 by the rear end portion of the bottomed cylindrical portion 61 that recedes.
It is turned in the direction.

Thereafter, 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 The retreating of the pressure receiving portion 61A with the slider portion 60 is continued by the gas flowing into the variable volume pressure chamber formed between the pressure receiving portion 20 and the end surface portion of the rear side portion. Thereby, the movable contact member 16 contacting the rear end of the movable bar 11 is released from the state where the position is regulated by the concave portion 60D provided on the bottom surface of the slider portion 60 as shown in FIG. At the same time, the slider portion 60 which is retracted is pressed in a direction against the urging force of the engagement piece portion 38B of the leaf spring member 38, and assumes a lower position. As a result, the movable contact member 16 and the rotating lever 1
5 is released from the mutual contact state with the lower portion 15A, and the rotating lever 15 rotates in a direction according to the urging force of the engaging piece 38A of the leaf spring member 38. Further, the lock member 31 disposed on the second hammer 7 is
With the retreat, the slider portion 60 as shown in FIG.
Is pressed downward against the urging force of the coil spring 32 by a projection 60C provided on the bottom surface of the toy gun main body 10 to be released from the mutual engagement state with the engagement portion 34 provided on the toy gun body 10, As a result, 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 portion 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 urging 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.

The rotation of the second hammer 7 in accordance with the urging force of the toggle spring 30 causes the gas passage opening / closing portion 45 to be positioned by the rotation arm 36 abutting on the rear end of the rod 51 provided thereon. It is released from the fixed state. The gas passage opening / closing portion 45 released from the fixed position by the rotation arm 36 closes the gas outlet passage portion 44 by the gas pressure acting on the gas passage opening / closing portion 45 and the urging force of the coil spring 52 as shown in FIG. Take the position.

Therefore, under such circumstances, the passage connecting portion 4

From the first state in which the gas pressure is applied to the bullet BB in the loading chamber 4, the first passage portion 49 </ b> A in the passage connection portion 47 is shut off, and the gas from the pressure accumulation chamber 43 through the gas outlet passage portion 44 is released. The flow toward the loading chamber 4 is prevented through the first passage 49A in the passage connecting portion 47 and the first internal space 23 in the movable member 20, and the pressure accumulation chamber 43 through the gas outlet passage 44 is prevented.
Of gas from the valve connecting space 48 in the passage connecting portion 47
And the second passage portion 49B, and further the movable member 20
The second internal space 24 generates a flow toward the pressure receiving portion 61A, and applies a gas pressure to the pressure receiving portion 61A.
Then, under the second state, the pressure receiving portion 61A is moved rearward with the slider portion 60 by the gas pressure.

As a result of the operation of the movable valve portion 46, 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 slider 60 is prevented from affecting the barrel 2 due to the movement thereof. Therefore, it is possible to prevent the bullet BB fired from the inner barrel 2I from being out of order.

Is biased in a direction to separate the large-diameter head 76A from the lower opening end formed by 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 of the movable member 70 at a position corresponding to the zero reference position is regulated so as to open the first internal space 73. The movable valve portion 76 whose position is regulated in this way is urged by the coil spring 80 to allow the gas from the accumulator 43 through the gas outlet passage portion 44 to pass through the passage connecting portion 77.
And a state where a flow toward the loading chamber 4 through the first internal space 73 in the movable member 70 can be generated.

The movable valve portion 76 accommodated in the valve accommodation space 78 moves in a direction to compress the coil spring 80 against the urging force of the coil spring 80 under a predetermined state described later. Then, when the slider portion 60 is at the reference position, the other end of the first internal space 73 in the intermediate portion of the movable member 70 which takes a position corresponding to the reference position of the slider portion 60 is formed. 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 provided at the lower opening end to be formed. The second internal space 74 in the movable member 70 is always open regardless of the movement of the movable valve portion 76. The movable valve portion 76, which is configured to shut off the first internal space 73, is connected to the first internal space 73 in the passage connecting portion 77 and the movable member 70 by the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44.
Through which the flow toward the loading chamber 4 is blocked.

Also in the example shown in FIG. 11 configured as described above, the slider portion 60 is once retracted by manual operation and released from the retreating operation, so that the bullet BB is added to the bullet chamber 4. Is loaded, the slider portion 60 is returned to the reference position, and the passage connecting portion 77 moves the gas outlet passage portion 44 through the valve housing space 78 to move the movable member 70.
Are connected to the first internal space 73 and the second internal space 74, respectively.

Then, the bullet BB is loaded into the loading chamber 4, and the passage connecting portion 77 connects the gas outlet passage portion 44 to the first internal space 73 and the second internal space 74 of the movable member 70 through the valve housing space 78. The movable valve portion 76 is urged by the coil spring 80 so that the gas from the pressure accumulating chamber 43 through the gas outlet passage portion 44 passes through the passage connecting portion 77 and the movable member 70. When the trigger 1 is pulled in a state where a flow toward the loading chamber 4 can be generated through the internal space 73 of the first hammer 7, the turning arm 36 attached to the second hammer 7 causes the gas passage opening / closing section 45 to move. Is pressed while compressing a coil spring 52 mounted on the rod 51, and the gas passage opening / closing portion 45 closes the gas lead-out passage portion 44 from the gas lead-out passage 44. 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 opened gas outlet passage 44 immediately flows into the passage connecting portion 77. At this time, 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 to open the first internal space 73 from the pressure accumulating chamber 43 through the gas outlet passage portion 44. Since the gas can flow toward the loading chamber 4 through the passage connecting portion 77 and the first internal space 73 in the movable member 70, the first internal space 73 and the second internal space in the movable member 70 are formed. 74 are both open. Therefore, the gas flowing into the passage connecting portion 77 flows through the passage connecting portion 7.
7, the valve housing space 78 in the movable member 70 flows through the first internal space 73 in the movable member 70 toward the loading chamber 4, and the gas is applied to the bullet BB in the loading chamber 4 and the movable member 70 Then, a flow toward the pressure receiving portion 61A is generated through the second internal space 74, and the 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 determined by the pressure receiving portion 61A, the bottomed cylindrical portion 61 and the slider portion 60. Is smaller than the gas pressure required to be moved rearward. Therefore, the pressure receiving section 6
Due to the gas pressure acting on the bullet BB in the loading chamber 4, the pressure receiving portion 61A does not move backward with the bottomed cylindrical portion 61 and the slider portion 60 due to the gas pressure acting on 1A. The bullet BB in the chamber 4 is pushed forward from the loading chamber 4 into the inner barrel 2I, and is discharged from the first internal space 73 in the movable member 70 into the inner barrel 2I by the gas flowing into the inner barrel 2I. The vehicle is accelerated and moves forward, and is projected from the tip of the inner barrel 2I and fired. In this way, the gas from the pressure accumulation chamber 43 will cause the firing of the bullet in the loading chamber 4.

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 into the atmosphere from the tip of the inner barrel 2I, whereby the inner The gas pressure in the barrel 2I and in the first internal space 73 of the movable member 70 rapidly decreases. Such a movable member 7
The sharp decrease in gas pressure in the first internal space 73 at 0 causes the movable valve portion 76 disposed in the valve housing space 78 of the passage connecting portion 77 to move the movable valve portion 76 to the first internal space 73 side of the movable member 70. Acting as a negative pressure drawn into the movable valve portion 7
6 is moved toward the first internal space 73 in the movable member 70 against the urging force of the coil spring 80, and the large-diameter head 76A in the movable valve portion 76 The first internal space 73 of the movable member 70 is shut off by contacting a valve receiving portion 73A provided at the lower opening end formed by the other end of the first internal space 73. Thereby, the movable valve portion 76 allows the gas flowing through the gas outlet passage portion 44 to pass through the passage connecting portion 77 and the first internal space 73 in the movable member 70 to the loading chamber 4.
The incoming flow will be blocked.

As described above, the flow of the gas flowing through the gas outlet passage portion 44 toward the loading chamber 4 through the passage connecting portion 77 and the first internal space 73 in the movable member 70 is prevented by the movable valve portion 76. 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
Without flowing into the internal space 73 of the movable member 70, a flow toward the pressure receiving portion 61A is generated through the second internal space 74, and the gas pressure acts on the pressure receiving portion 61A. The pressure increases sharply. Thereby, the pressure receiving portion 61 is increased by the increased gas pressure.
A is rapidly moved rearward while increasing the variable volume pressure chamber formed between the movable member 70 and the end face of the rear side portion in the bottomed cylindrical portion 61, and accordingly, the slider portion is moved. 60 is quickly 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 retreat.

The subsequent operation proceeds in the same manner as the operation in the example shown in FIG.
The movable member 70 is retracted to the rearmost position of zero and the slider portion 60 is retracted, and further, the slider portion 60 is returned to the reference position by advancing the movable member 70 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 of 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. Under the corresponding position, the gas outlet passage portion 44 extending from the pressure accumulating chamber 43 is 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, and During the period in which the passage opening / closing portion 45 opens the gas outlet passage portion 44, the first internal space 73 in the movable member 70
In the open state, the flow of the gas through the gas outlet passage 44 through the valve housing space 78 in the passage connecting portion 77 and further through the first internal space 73 of the movable member 70 is generated toward the loading chamber 4, Bullet BB in the loading chamber 4
The first internal space 73 in the movable member 70 is closed from the first state in which the gas pressure acts on the valve housing space 78 in the passage connecting portion 77 and the movable member 70 in the passage connecting portion 77. Through the first internal space 73, the flow toward the loading chamber 4 is blocked, and the gas through the gas outlet passage portion 44 passes through the valve housing space 78 in the passage connection portion 77, and further, the second inside of the movable member 70 A flow toward the pressure receiving portion 61A is generated through the space 74, and the state shifts to a second state in which gas pressure acts on the pressure receiving portion 61A.
1A is moved backward with the slider section 60.

Then, 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 slider 60 is prevented from affecting the barrel 2 due to the movement thereof. Therefore, it is possible to prevent the bullet BB fired from the inner barrel 2I from being out of order.

The structures of the movable member 20 or 70 and the passage connecting portions 47 or 77 in each of the example shown in FIG. 2 and the example shown in FIG. 11 are described in claims 1 to 5 in the claims of the present application. The main part of the configuration to be provided in the toy gun with an automatic bullet supply mechanism according to the invention described in any one of the above items 5 to 5 is illustrated, and the present invention is not limited thereto. That is, the toy gun with an automatic bullet supply mechanism according to any one of claims 1 to 5 in the claims of the present application has a specific configuration different from that of the movable member 20 or 70 described above. Needless to say, the movable member may be configured to include a passage connecting portion having a specific configuration different from that of the above-described passage connecting portion 47 or 77.

[0085]

As apparent from the above description, according to the toy gun with the automatic bullet supply mechanism according to the invention described in any one of claims 1 to 5 in the claims of the present application, the pressure accumulation A gas outlet passage extending from the chamber and controlled to be opened / closed by the gas passage opening / closing portion is shared by the passage connecting portion with both the first internal space and the second internal space of the movable member according to the position of the movable member. And the gas outlet passage portion is connected to both the first internal space and the second internal space of the movable member via the passage connection portion, and the movable valve portion passes through the gas outlet passage portion. The first gas in the passage connecting portion and the movable member from the pressure accumulating chamber
Is controlled through the gas storage passage through the gas discharge passage through the gas discharge passage because the flow toward the pressure receiving portion through the passage connection portion and the second internal space in the movable member is controlled. The gas pressure is applied to the bullets in the chamber, thereby controlling the gas which causes the firing of the bullets in the loading chamber, and applying the gas pressure to the pressure receiving section which is led out from the accumulator through the gas outlet passage and thereby receives the pressure. The control of the gas that causes the retreat with the slider portion of the portion can be reliably performed with a relatively small-scale and simplified configuration.

Further, according to the toy gun with the automatic bullet supply mechanism according to the invention described in claim 2 or 5 in the claims of the present application, the movable valve portion is disposed in the passage connecting portion. Therefore, a space for accommodating the movable valve section can be secured with good space utilization efficiency, and the movable member can be reliably operated.
