Abstract

PURPOSE:To obtain a toy air gun for shooting a bullet by utilizing compressed air produced by a motor-driven compressor provided in a gun body. CONSTITUTION:A compressor 10 to be driven by a motor 9 is provided in a gun body, its discharge port is connected to an air tank 4 having a pressure sensor 3, and a valve 12 to be switched by a trigger 11 is provided between an air tank 4 and a chamber 7.

Description

Description: TECHNICAL FIELD The present invention relates to an air gun toy for firing a plastic bullet having a diameter of 6 mm, which is called a BB bullet, by using compressed air. Conventionally, in the air gun as described above, a spring type that pushes a piston in a cylinder with a spring and shoots a bullet with the compressed air, and a compressed gas such as compressed air or CFC gas from outside is sent, and the bullet is blown by the pressure gas. There is a gas type to fire, but in the spring type, it is necessary to push down the piston and compress the spring with each shot, and it is not possible to continuously fire just by pulling the trigger. An external air source such as an air tank is required, and the gas pressure of CFC gas easily changes depending on the temperature, so the bullet velocity is not constant and there are problems such as environmental damage. It had the disadvantage of requiring a large size and being bulky and inconvenient to carry. The present invention is characterized in that a mechanism of a gas type air gun is used, and air is used as a firing source to produce compressed air in the gun body. The embodiment will be described below with reference to the drawings. Is the street. A compressor 10 driven by a motor 9 is provided in, for example, a stock of the gun body, and its outlet and an air tank 4 equipped with a pressure sensor 3 are connected by a pipe 14, and the air tank 4 and the chamber 7 are connected by a trigger 11 on the way. The pipes 5 and 6 are connected via a valve 12 that is opened and closed. The motor 9 is wired by inserting the power switch 1 into the battery 2 provided outside or inside the gun body. FIG. 2 is an example of an arrangement when actually assembled in a gun. The operation of this embodiment will be explained. First, when the power switch 1 is turned on, the motor 9 is rotated to drive the compressor 10, and the compressed air produced therein is filled in the air tank 4 through the pipe 14. When the air pressure in the air tank 4 reaches a certain standard, the pressure sensor 3 works to turn off the power and stop the motor 9 and the compressor 10. This enables the gun to fire, and when the trigger 11 is pulled and the valve 12 is opened, the compressed air in the air tank 4 enters the chamber 7 through the pipes 5 and 6 and the bullets that enter the chamber 7 from the magazine 13. Are fired through the barrel 8 by compressed air. Depending on the capacity of the air tank 4, when dozens of bullets are fired, the air pressure in the air tank 4 decreases and the pressure sensor 3 works to turn on the power, the motor 9 rotates, and the compressed air enters the air tank 4 by the compressor 10. It is filled up to a certain atmospheric pressure, and the pressure sensor 3 works to automatically stop the motor 9 and the compressor 10. This invention uses the gas-type firing mechanism as it is, and only the firing source is manufactured in the gun body. The use of CFCs, which was a drawback of the conventional gas-type, and the external air tank It is not necessary to use it, and if a rechargeable battery is used as the power source, the operating cost can be extremely low. As described above, the present invention easily solves the drawbacks of the conventional air gun, and has excellent performance in the related art such as continuous firing and a constant bullet velocity.
