JPH07151494A - Mechanism for shooting nd automatic feeding of bullet in air type of gas pressure type - Google Patents

Abstract

PURPOSE:To make a motion light and to obtain reality by changing over the direction of the motion of piston of a air cylinder automatically under an air pressure or a gas pressure after a bullet in a shooting part is shot by the air pressure or the gas pressure, and by sending a subsequent bullet automatically into the shooting part. CONSTITUTION:By pulling a trigger 15 in a state wherein a projection 3 is charged in a shooting part 10 of a gunbarrel 9, air or gas is supplied to an air supply part 13 of a piston 12 and the projection 3 is shot under the pressure thereof, while the piston 12 is moved back by the reaction of the shooting. Then the communication of an air supply port 6 with the air supply part 13 is cut, the direction of release of the air or the gas is changed over automatically, and when the piston 12 is moved back further to a maximum stroke approximately, a subsequent bullet 3 is made to rise to the fore end position of the piston 12 and pushed into the shooting part 10 automatically. According to this constitution, a load applied on the trigger holds down a valve alone and so a force required for pulling the trigger becomes light.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a play gun used indoors and outdoors, and more particularly to a bullet firing and automatic bullet feeding mechanism in an air type or gas pressure type play gun.

[0002]

2. Description of the Related Art A conventional play gun is mainly constructed by manually operating an engine section to insert a bullet into a launching section and instantaneously release air or gas to launch the bullet. Is.

[0003]

That is, the conventional play gun is mechanically manually or by a spring or the like, a bullet is fed to a firing portion through a trigger to instantaneously release air or gas, or a spring. The bullet is fired by applying pressure and the like momentarily, and the trigger is heavy and the hand becomes painful.

Therefore, a method of sending a bullet to the firing section by utilizing air or gas pressure has been put into practical use. However, in this method, the first bullet is pulled back to the firing section by hand and returned to the firing section. It is something to send. Then, by pulling the trigger, the slide portion is moved backward by air or gas pressure. A bullet is fired in the middle of the back, and in reaction to that, the slide part is further moved back and returned, and the next bullet is sent to the firing part in the middle.

However, this method cannot be said to have good accuracy because the bullets are fired while the slide portion is moving.

The bullet firing and automatic bullet feeding mechanism in the air-type and gas-pressure type play guns of the present invention is intended to solve the above-mentioned drawbacks of the conventional example, and a light operation can be obtained by using a mechanism close to a real gun. The present invention provides a bullet firing and automatic bullet feeding mechanism in an air-type and gas-pressure type play gun which can obtain a realistic feeling.

[0007]

A bullet firing and automatic bullet feeding mechanism in an air-type and gas-pressure type play gun according to the present invention includes an air cylinder equipped with a piston incorporated inside the play gun, an air pressure, After firing the bullet in the firing section by gas pressure, the operation direction of the piston is automatically switched by air pressure and gas pressure, so that the bullet is automatically fed to the firing section.

Further, the air or gas discharge path is set such that when the magazine is mounted, the air supply port in the magazine is fitted to the air or gas receiving port of the air cylinder. Since the bullets are not fitted with each other each time they are fired, it is also characterized by eliminating the variation in bullet speed each time they are fired.

Further, according to the present invention, the bullet is fired by air or gas pressure, the piston is moved back by the air or gas pressure in the muzzle at that time, and the next bullet is sent to the firing part, which has the same function as a real gun. One of the features is that it has.

[0010]

According to the bullet firing and automatic bullet feeding mechanism of the air type and gas pressure type play guns of the present invention, the game guns using air or gas pressure are provided with the pistons to be operated by utilizing the pressures. An air cylinder mechanism is provided. Therefore, if the piston retreats by a certain amount after the bullet is fired by air or gas pressure as in a real gun, the direction in which the air or gas pressure is applied automatically changes and the piston moves backward by air or gas pressure. The upper case also retreats like a real gun by pushing it down. The bullet can then be automatically pushed into the firing section when the piston returns to its original position.

As a result, the load related to the trigger becomes only the force for holding down the valve, the force for pulling the trigger is lightened, and since the bullet is fired before the piston retracts, the hand shake is reduced and the accuracy is increased. .

Further, the air or gas discharge path is mechanically fixed from the time the magazine is attached to the time it is extracted, and the air supply port of the magazine and the receiving port of the air cylinder block separate each time a bullet is fired. Therefore, pressure fluctuations are less likely to occur.

According to the bullet firing and automatic bullet feeding mechanism of the air type and gas pressure type play guns of the present invention, a piston which is operated by utilizing the pressure is provided in the play gun using air or gas pressure. The air cylinder mechanism provided is provided. Therefore, if the piston retreats by a certain amount after the bullet is fired by air or gas pressure as in a real gun, the direction in which the air or gas pressure is applied automatically changes and the piston moves backward by air or gas pressure. The upper case also retreats like a real gun by pushing it down. The bullet can then be automatically pushed into the firing section when the piston returns to its original position.

As a result, the load related to the trigger becomes only the force for holding down the valve, the force for pulling the trigger is lightened, and since the bullet is fired before the piston retracts, the camera shake is reduced and the hit rate is increased. .

Further, the air or gas discharge path is mechanically fixed from the time the magazine is attached to the time it is extracted, and the air supply port of the magazine and the receiving port of the air cylinder block separate each time a bullet is fired. Therefore, pressure fluctuations are less likely to occur.

In the method of the present invention, in order to increase the bullet velocity with a constant air or gas pressure, the pressure for pushing the piston backward is not taken more than necessary, and a spring or the like is used in the operating direction of the piston. By increasing the load force that pushes down the piston and increasing the pressure in the bullet firing direction,
That purpose can be achieved.
