Description

[Detailed description of the invention] Industrial application field This invention relates to a toy gun that uses a jet of compressed gas.
In particular, the present invention relates to a toy gun having a feature of discharging cartridges.

BACKGROUND ART Recently, toy guns have been known in which a container is filled with compressed gas such as liquefied fluorocarbon gas and the pressure is used to fire a bullet. In this case, the pressure of the compressed gas filled in the container is high at the beginning of use, but the pressure decreases at the end of use. Therefore, if the compressed gas in the container is immediately led to the bullet storage part using a pipe, when the bullet is fired many times and there is little compressed gas left in the container, the bullet will not fly out as vigorously as it originally did. The firing power gradually weakens.

In order to compensate for these drawbacks, a cylinder is provided in the gun body, and the gas storage chamber of the cylinder is connected to an air supply pipe that communicates with the compressed gas container, and also communicates with the bullet storage section located at the base end of the gun barrel. The exhaust pipe is connected to the exhaust pipe, and the exhaust pipe is opened and closed by a valve body that operates in conjunction with a trigger, and a force is applied to the piston in the cylinder in the direction of contracting the gas storage chamber by a compression spring. .

As described above, when the compressed gas in the container is once filled into the cylinder, the pressure spring is stored, and the force of this pressure spring is used to send gas to the bullet and cause the bullet to fire, thereby releasing the compressed gas in the container. When the pressure of the compressed gas drops to a constant pressure, the push spring (as their elastic force is constant) cannot be stored, and therefore, at this time, the compressed gas container must be replaced with an unused compressed gas container. Bullets are always fired with a constant force.

Problems to be Solved by the Invention However, as described above, the movable part of the gun toy is moved in conjunction with the piston, which operates while contracting the spring by the compressed gas that is sent from the container to the storage chamber of the cylinder. If you can make it work, you won't have to manually operate it, which is convenient, but there hasn't been a gun toy like this before. The purpose of the present invention is to propose a gun toy made in view of the above-mentioned drawbacks.

Means for Solving the Problems The present invention provides a toy gun in which a bullet is positioned at the base end of the gun barrel, and the bullet is fired by a jet of compressed gas when the trigger is operated. A cylinder communicated via an air supply pipe is provided in the gun body, and an exhaust pipe led out from the cylinder is guided to the bullet storage section, and a charge is placed at the tip of a piston rod attached to a piston that slides inside the cylinder. A medicine discharge claw that can be engaged with the constriction of the cylinder is pivotally supported, and a valve body for opening and closing an exhaust hole communicating with the exhaust pipe is provided in the cylinder, and the valve body has the following features:
attaching an operating rod that is biased to close the discharge hole and whose rear end is led out of the cylinder;
