Description

  The present invention has a magazine that is detachably attached to a gun body, supplies bullets inside the magazine to a loading portion of the gun body, and jets compressed air to the bullets arranged in the loading portion. The present invention relates to a safety device in a simulated gun having a piston device.

  For example, a gun called an airsoft gun or a play gun uses a spherical bullet, commonly called a BB bullet, manufactured according to a certain standard, and this type of gun has a supplementary bullet. Some magazines are detachable and others are not. In magazine detachable guns, bullets may remain retained in the loading section even when the magazine is removed from the gun body. In such cases, care should be taken when triggering carelessly, as some guns will fire the remaining bullets, especially for guns that are targeted at the youth. There is a need to. If the remaining bullets are exhausted, there will be no such problem, but depending on the time and circumstances, it may not be possible.

  The above-mentioned type of gun that can cause inadvertent firing is that the bullet is left in the loading part even when the magazine is removed from the gun body, and the function that can inject compressed air is alive, It is a gun that satisfies the condition. For example, in the case of a type of gun that has a tank filled with compressed gas integrated in the magazine, if the magazine is removed from the gun body, the gas will not be injected even if the trigger is pulled. It can be said that there is no fear of being fired. Also, for guns with a motor-driven piston device, such as an electric gun, it is possible to link the attachment and detachment of the magazine with the opening and closing of the motor drive circuit. It is possible to take measures to cut off.

  On the other hand, the piston is manually driven by pulling the trigger, and the structure is such that compressed air is injected, the structure is relatively simple, and the power is relatively small. In the case of this gun, the bullet remains in the gun body even when the magazine is removed from the gun body, and the function of injecting compressed air is still alive, so the firing conditions are provided. For this reason, in the above-described gun, there is a risk that the remaining bullets are fired by the firing operation after the magazine is removed from the gun body, and therefore, it is highly necessary to take measures. However, for other types of guns than the above-mentioned guns, it is useful to prevent the risk of residual bullet firing that may occur inadvertently after removing the magazine from the gun body.
