Among such toy guns, the one imitating a gun in which a slider attached to a barrel is moved in response to operation of a trigger, wherein a bullet loaded in a loading chamber provided at a rear end of the barrel is used. It is known that, in addition to firing by gas pressure, bullets are supplied to the loading chamber by gas pressure. For example, as shown in Japanese Utility Model Application Laid-Open No. 3-38593, a pressure storage cylinder, a magazine, a first and a second valve, which are filled with air and provided with a gas outlet passage controlled to be opened and closed by an on-off valve, The first and second gas passages and the bullet supply lever are arranged on the grip portion, and are arranged in the slider arranged for the barrel provided with the impact hole through the magazine plate forming the impact hole. A cylinder opposed to the barrel is provided, and further, 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 is provided. There has been proposed a toy gun adapted to use the pressure of air to fire a bullet loaded in a landing hole and supply the bullet to the landing 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 supply state, the piston member housed in the cylinder retreats the slider by the pressure of the air supplied into 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, as the slider is retracted, 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 the rotary cam. As a result, the impact holes in the magazine plate
It is moved from the initial position facing the muzzle to a position facing the bullet discharged from the magazine. Then, the bullet ejected from the magazine is loaded into the impact hole by the bullet supply lever which is swung in conjunction with the trigger. Under such circumstances, when the cylinder is evacuated and the slider returns to the original position, the spring member is returned to the original position to return the spring guide member to the original position, whereby the rotating cam moves the magazine plate. It is rotated in the ascending direction, 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 by the hammer rotating in conjunction with the trigger. The air 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 return to the initial state of the slider. Fired.

[0004]

As described above, a cylinder forming a pressure chamber to which air from a pressure storage cylinder is supplied is disposed in a slider provided so as to be able to move backward and forward with respect to a barrel, and a trigger is provided. The slider is moved by the supply and discharge of air to and from the pressure chamber, whereby the bullet is supplied to the impact hole, and the firing of the bullet supplied to the impact hole is performed by using the air from the accumulator cylinder. In a toy gun adapted to be performed, automatic firing of bullets is possible. However, in a conventionally proposed toy gun provided with a slider that moves using air from the pressure storage cylinder as described above, when the trigger is pulled, the slider is first moved backward, Subsequent firing of bullets is performed, and if the movement of the slider is performed before firing of the bullet in this way, the barrel portion will be affected by the movement of the slider when firing the bullet, There is a possibility that the trajectory of bullets fired from the barrel will be out of order.

In view of the foregoing, the present invention provides a pressure accumulating chamber, and uses a gas filled in the pressure accumulating chamber to fire a bullet loaded in the ammunition chamber and supply the bullet to the ammunition chamber. The present invention provides a toy gas gun in which the movement of the slider is started after the bullet loaded in the loading chamber is fired when the movement of the slider is performed.

Is placed in a position where it comes into contact with the rear end of the fixing member 51 as shown by a solid line in FIG. Launching movable pin 40 beaten by hammer 5
Is pressed in a direction against the urging force of the coil spring 46. Accordingly, the piston member 35 is pressed by the rod 43 attached to the movable pin 40 for firing in a direction against the urging force of the coil spring 39. When the piston member 35 is pressed in this manner, the movable lever 45 is moved upward by the urging force of the coil spring 44, and presses the piston member 35 in a direction against the urging force of the coil spring 39. And a valve portion 35 provided on the piston member 35.
a is maintained at a position where the other end of the connection gas passage 36 is opened.

Thus, the bullet firing gas passage 21 opened by the valve member 27 of the gas passage control unit 25 and the pressure accumulating chamber 33 provided in the case 30 are in communication with each other, and The gas from the accumulator 33, which is supplied to the central space 20 in the movable member 54 through the upper gas passage 38, flows around the rod 26 forming the gas passage control unit 25 disposed in the bullet firing gas passage 21. Through the formed space , a state of being supplied into the loading chamber 4a is obtained. As a result, as shown by the solid line in FIG. 5, the bullet BB loaded in the bullet chamber 4a is moved by the gas pressure from the accumulator 33 over the annular protrusion 4b as shown by the one-dot chain line in FIG. The barrel 2 is moved to the front part of the annular member 4 in a state where the barrel 2 and the bullet firing gas passage 21 are shut off.

In this case, the movement of the rod 26 according to the urging force of the coil spring 28 is prevented by the gas pressure from the pressure accumulating chamber 33 acting on the valve member 27 that closes the bullet supply gas passage 22. The position where the bullet supply gas passage 22 of the valve member 27 is closed is maintained. And
The bullet BB that has moved to the front side portion of the annular member 4 is
When the gas is moved into the barrel 2 by the gas pressure from the accumulator 33, gas leaks into the barrel 2 through a relatively small gap generated between the barrel 2 and the bullet BB, and the gas in the barrel 2 of the bullet BB The movement toward the front end portion is accelerated, and the gas pressure in the central space 20 decreases.

As the gas pressure in the central space 20 decreases, the rod 26
As a result, the valve member 27 is moved from the bullet supply gas passage 22 toward the bullet discharge gas passage 21 as shown in FIG. Then, the valve member 27 is advanced by the advance of the rod 26 due to the decrease in the gas pressure in the central space 20 as described above.
However, the bullet BB that has been moved into the barrel 2 is fired from the barrel 2 until the bullet firing gas passage 21 is closed as shown in FIG.

The valve member 27 closes the bullet firing gas passage 21, and connects the bullet supply gas passage 22 to the upper gas passage provided in the case 30 via the central space 20 and the common gas passage 23. 38, the pressure accumulating chamber 33 filled in the bullet supply gas passage 22.
From the fixed member 51 through a communication passage provided at the rear end of the bullet supply gas passage 22.
It flows into the fixing member 51 while being pressed in a direction of separating from the fixing member 51. As described above, a state in which the slider portion 50 is pushed rearward by the gas pressure from the pressure accumulating chamber 33 flowing into the fixing member 51 is obtained. Thereby,
The slider portion 50 is retracted against the urging force of the coil spring 18, the first movable cylindrical portion 52A is protruded from the inside of the fixed member 51 toward the annular member 4, and the second movable cylinder A member 52B is protruded from the first movable cylindrical member 52A toward the annular member 4. Therefore, after the bullet BB loaded in the loading chamber 4a is fired, the retreat of the slider portion 50 is started.

Further, the hammer 5 is rotated in the direction opposite to the direction a by the fixing member 51 which retreats with the slider part 50 which retreats, against the urging force of the coil spring 41. As a result, as shown in FIG. 8, the fixed member 51 and the first and second movable cylindrical members 52A and 52A
2B, a variable-volume pressure chamber 56 to which the gas pressure from the accumulator 33 is supplied through the bullet supply gas passage 22 is formed, and the hammer 5 is moved from the movable pin 40 for firing. The movable pin 40 for firing is moved away from the position shown by the solid line in FIG.
Is moved to a position protruding from the grip 6 as shown by the dashed line.

After the bullet BB is fired from the barrel 2 in this manner, the fixing member 51 is passed through the bullet supply gas passage 22.
Since the retraction of the slider portion 50 is started by the gas pressure from the pressure accumulating chamber 33 supplied to the inside, when the bullet BB is fired, it is avoided that the slider portion 50 exerts the influence of the movement on the barrel 2 when the bullet BB is fired. In this way, the trajectory of the bullet BB fired from the barrel 2 is prevented from being out of order.

When the slider portion 50 is further retracted by the gas pressure supplied from the pressure accumulating chamber 33 to the pressure chamber 56 having a variable volume, the movable bar 8 is moved by the lower end of the second portion 50B of the slider portion 50. Is rotated in a direction in which the rear portion thereof descends. Thereby, the locking portion 8 provided on the rear side portion of the movable bar 8
a is disengaged from the rotating lever 15, and the rotating lever 15 rotates in a direction in accordance with the biasing force of the toggle spring 16 and contacts the hammer 5. Further, the movable lever 4 which engages with a protruding portion 8b provided on the rear side portion of the movable bar 8
5 is pressed downward against the urging force of the coil spring 44, and the piston member 35 is released from the position fixed by the movable lever 45.
Is moved to a position where the leading end protrudes from the case 30. As a result, as shown in FIGS. 9 and 10, the hammer 5 is fixed at a position separated from the movable pin 40 for firing by the rotating lever 15, and the valve portion 35a of the piston member 35 is connected to the connecting gas passage. When the other end of 36 is placed in a closed state, the supply of gas pressure from the accumulator 33 to the pressure chamber 56 having a variable volume is stopped.

Immediately after the supply of the gas pressure from the pressure accumulating chamber 33 to the pressure chamber 56 of the variable volume is stopped, the slider section 50 is further retracted due to its inertia. Immediately before the slider section 50 assumes the last retreat position due to the retreat due to its inertia, the state in which the volume of the variable volume pressure chamber 56 is maximized, that is, the first and second movable cylinders forming the pressure chamber forming section The projecting lengths of the members 52A and 52B are maximized, and the movable member 54 is in a state of being locked to the second movable cylindrical member 52B by its rear side portion, whereby
The movable member 54 retreats together with the slider 50 that retreats due to inertia. As a result, the uppermost end 31a of the magazine 31 closed by the intermediate portion of the movable member 54
Is opened, the uppermost portion of the bullets BB filled in the magazine 31 is pushed up and held by the uppermost end portion 31a, and the lower side portion of the movable member 54 and the upper end portion of the case 30 With a state in which a space is formed between the upper gas passage 38 provided in the movable member 54 and the upper gas passage 38 provided in the case 30, the gas in the pressure chamber 56 having a variable volume is ,
It is discharged to the atmosphere through the bullet supply gas passage 22, the central space 20 and the common gas passage 23.

When the gas pressure in the variable-volume pressure chamber 56 starts to decrease, the movable member 54 is moved by the urging force of the coil spring 55 to move the first and second movable cylindrical members 5.
2A and 52B are retracted while keeping the retracted state. Thereby, the second movable cylindrical member 52B is accommodated in the first movable cylindrical member 52A, and the first movable cylindrical member 52A is disposed in the fixed member 51, and the movable member 54 fixes the intermediate portion thereof. The member 51 is brought into contact with the member 51. In such a case, the slider unit 50
Takes the last retreat position. As soon as the slider portion 50 is at the rearmost position, the slider portion 50 is immediately moved forward by the urging force of the coil spring 18 and the slider portion 50 is moved.
The movable member 54, which advances with the advance of, transports the bullet BB held at the uppermost end 31a of the magazine 31 by its front end toward the loading chamber 4a.

As a result, when the slider portion 50 assumes the reference position, as shown in FIG. 4, the bullet BB is securely loaded into the bullet chamber 4a, and the movable member is moved by the bullet BB. The rod 26 of the gas passage control unit 25 in 54 is retracted, and the valve member 27 closes the bullet supply gas passage 22 to connect the bullet firing gas passage 21 to the central space 20 and the common gas passage 23. Through the upper gas passage 38 provided in the case 30. Under such circumstances, when the trigger 1 is returned from the firing completion position to the firing preparation position, the movable bar 8
Is returned to the position before the trigger 1 was pulled. Then, when the trigger 1 is pulled again, the bullet BB is fired in the loading chamber 4a and the subsequent supply of the bullet BB to the loading chamber 4a is performed as described above.

As described above, between the loading chamber 4a formed by the annular member 4 and the pressure chamber forming portion including the fixed member 51 and the first and second movable cylindrical members 52A and 52B. A gas passage control unit 25 shared by a bullet supply system and a bullet firing system is provided in a movable member 54 disposed above the grip 6, whereby a total of 1
The common gas passage 23, the upper gas passage 38, the connecting gas passage 36, and the lower gas passage 37, which form the gas passage portion,
Each of the bullet firing gas passage 21 and the bullet supply gas passage 22 controlled to be opened and closed by the gas passage control unit 25 is shared, and the gas passage control unit 25 and the loading chamber 4a and Since the distance between each of the pressure chamber forming portions and each of the pressure chamber forming portions is relatively small, the bullet firing gas passage 21 and the bullet supply gas passage 22 are shortened. 4a, and the entire gas passage from the pressure accumulating chamber 33 to the variable volume pressure chamber 56 through the inside of the movable member 54 is effectively shortened, and the structure is relatively simple. become.

Moreover, the grip-side gas passage portion formed by the upper gas passage 38, the connecting gas passage 36, and the lower gas passage 37 provided in the case 30 and positioned in the grip 6 is used for projectile firing. Along with the fact that the gas passage 21 and the bullet supply gas passage 22 are commonly used to make the configuration relatively simple, the case 30
Since there is an extra space inside, it is easy to increase the volume of the pressure accumulating chamber 33.

Further, the entire gas passage from the pressure accumulating chamber 33 to the loading chamber 4a through the inside of the movable member 54 and the entire gas passage from the pressure accumulating chamber 33 to the variable volume pressure chamber 56 through the inside of the movable member 54 are reduced. As a result, the amount of gas consumed for firing the bullet BB from the barrel 2 and supplying the bullet BB to the loading chamber 4a is reduced, whereby the pressure in the accumulator 33 is gradually reduced. Therefore, for a long time after the gas is filled in the accumulator 33, a gas passage control unit that controls opening and closing of the bullet firing gas passage 21 and the bullet supply gas passage 22 by the gas pressure from the accumulator 33. As a result, the slider section 50 moves smoothly along the barrel 2, and the bullet BB loaded in the bullet chamber 4a is smoothly fired.

In the above example, the case 30 having the pressure accumulating chamber 33 in which the liquefied gas is filled in the grip 6 is used.
Is disposed, but in the toy gas gun according to the present invention, the pressure accumulating chamber may be replaced with a liquefied gas, for example, may be filled with compressed air. Or, with a gas cylinder filled with compressed air with its gas inlet connected to the accumulator,
By being mounted on the grip, the gas pressure used for supplying and firing the bullet may be stored more.

[0042]

As is apparent from the above description, in the toy gas gun according to the present invention, the firing of the bullet loaded in the loading chamber and the movement of the slider portion for supplying the bullet to the loading chamber are performed by: When the operation is performed using the gas charged in the accumulator, when the trigger is pulled, the normally closed valve portion is opened, and the gas from the accumulator is distributed by the sliding member having the rod portion. is supplied to the space portion of the spatial portion formed in the member, the sliding member disposed in the space portion forming member, the rod portion
There is a space around it to send gas from the accumulator to the loading chamber.
By being as was done, the gas from the pressure accumulating chamber that will be supplied to the space portion of the space portion forming member, the sliding member
Bullet through the space formed around the rod portion is supplied to the bullet holding chamber loaded, whereby the bullet loaded in the bullet holding chamber is et moved into the barrel portion. And when the bullet loaded in the loading chamber is moved into the barrel ,
Sliding member, gas definitive the space portion of the space portion forming member pressure
The gas supplied to the space moves as the
Slider retraction that acts to move the slider backward
Cause a condition .

Accordingly, the bullet loaded in the loading chamber is a barrel portion.
After being moved within, will be movement of the slider is started, therefore, morphism <br/> onset bullet loaded in the bullet holding chamber is affected by the movement of the slider portion, barrel portion It is possible to prevent a situation in which the trajectory of a bullet fired from the target is deviated.
