ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to toy guns and more particularly to a toy gun for firing the paint bullets which toy gun is characterized in the rapid changing of its air pressure container and provides suitable air pressure to the gun for firing a paint bullet.
In a battle game, the teenagers use the toy guns to shoot each other with the paint bullets in order to obtain a great fun among them. These toy guns include pistol, rifle and/or machinegun for a single firing or continuous firing of the paint bullets by using the air pressure from a gas or pneumatic container. However, they have the common disadvantage that the air pressure is supplied by an external pneumatic source so that the teenagers have to carry a heavy gas container on their shoulders, causing a great burden and inconvenience to them.
SUMMARY OF THE PRESENT INVENTION
The present invention has a main object to provide a structurally improved toy gun for firing a paint bullet which includes a chamber in a rear side to enable the gun to carry a mini-gas can itself for providing suitable air pressure to fire a paint bullet. The mini-gas can is readily replaceable so as to provide great convenience to the user.
Another object of the present invention is to provide a structurally improved toy gun for firing a paint bullet which is readily to assemble or disassemble.
Further object of the present invention is to provide a structurally improved toy gun for firing a paint bullet in which a safety device is provided to prevent the gun from being inadvertently triggered.
The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.
