Description

Safety equipment for simulated guns

The present invention has a magazine that is detachably attached to the gun body, supplies the bullets inside the magazine to the loading part of the gun body, and injects compression to the bullets arranged in the loading part. The present invention relates to a safety device in a simulated gun having a piston device for the purpose. Memorandum

Background art

For example, airsoft guns, which are also called force or play guns, use spherical bullets, such as BB 弹, manufactured according to certain standards. Some magazines with magazines (magazines) are detachable and others are not. For magazine detachable guns, bullets may remain retained in the loading section when the magazine is removed from the gun body. In such a case, care should be taken when triggering carelessly, as some guns will fire the remaining bullets, especially for guns targeting younger people. It needs to be aroused. If the remaining bullets are exhausted, there will be no such problem, but in some cases it may not be possible, so countermeasures are desired.

The types of guns that can cause inadvertent firing are the functions in which bullets remain in the loading section and compressed air can be injected even when the magazine is removed from the gun body. 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 bullets being fired. Also, for guns with a motor-driven Biston 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, so by removing the magazine from the gun body, It is possible to take measures to cut off the switch. In the case of a hand-operated gun intended for young people, it has a structure in which the driver S is injected by a piston by pulling the pull, the structure is relatively simple, and the power is relatively small Even if the magazine is removed from the gun body, the bullet remains in the gun body, and the function that can inject compressed air is still alive, so it has firing conditions. For this reason, in the above-mentioned gun, there is a risk that the remaining bullets will be fired by the firing operation after removing the magazine from the gun body, and therefore it is also necessary to take countermeasures. However, for other types of guns than the above, it is useful to prevent the risk of fire of remnants that could occur inadvertently after removing the magazine from the gun body. Disclosure of the invention

Problems to be solved by the invention

The present invention has been made paying attention to the above circumstances, and the problem is that in a gun having a magazine that is detachably attached to the gun body, there is a risk of residual bullet firing that may occur after the magazine is removed from the gun body. Is to prevent sex. Another object of the present invention is to provide a safety device for a simulated gun that can prevent the gun from being accidentally discharged due to carelessness.

Means for solving the problem

In order to solve the above-mentioned problems, the present invention has a magazine that is detachably attached to a gun body, supplies bullets inside the magazine to the loading part of the gun body, and compresses the bullets arranged in the loading part In a simulated gun having a piston device for injecting air, the piston side device is attached to the gun body in order to retract the piston of the piston device in accordance with a firing operation in the drive unit. A trigger member having an engagement counterpart that engages with the joint and disengages from the engagement to advance the piston, and the trigger member is movable in the forward and backward direction of the piston, and The gun body is provided so that it can move in the direction in which the mating part is removed from the engaging part, and for the trigger member, a return spring is provided to assist the movement of the piston in the same direction. As a biasing means for biasing one trigger member in the direction in which the engaging portion and the mating mating portion are engaged, a means of using an elastic body equipped in the magazine is provided. . In order to have a configuration in which the bullets in the main part are supplied to the bullet loading part of the gun body, the bullets remain in the bullet loading part even after the magazine is removed from the gun body, and the remaining bullets On the other hand, it is intended for a simulated gun in which the Biston device, which is a function for injecting compressed air, is alive. Among the mock guns that satisfy this condition, there is a manual gun for young people that has a structure in which the piston is manually driven by pulling the trigger and compressed air is injected. However, for example, an electric gun is also a subject of the present invention because a viston device that is a function for injecting compressed air to the remaining testicles may be alive. The simulated gun used in the present invention means a gun that is not intended to be killed in contrast to a gun intended for killing, that is, an actual gun.

In the safety device according to the present invention, the piston is engaged with the engagement portion on the piston side in order to retract the biston of the biston device in accordance with the firing operation in the drive unit, which is equipped on the gun body, and the engagement A trigger member having an engaging counterpart for moving the piston forward from the piston. The trigger member is provided in the gun body so as to be movable in the forward and backward direction of the biston and movable in a direction in which the mating counterpart is removed from the engaging portion. In other words, the trigger member is a member that connects the drive unit mounted on the gun body and the viston, and transmits the movement accompanying the firing operation in the drive unit to the piston and moves it backward. An engagement part is provided on the side, and an engagement partner part is provided on the trigger one member side. When the piston is retracted, the engagement part and the engagement partner part are engaged, and when the piston is advanced, the engagement part is engaged. Release the mating part. Therefore, the trigger member is required to have a configuration in which the gun body can be moved in the direction in which the piston moves forward and backward, and can be moved in the direction in which the mating portion is removed from the engagement portion. However, as long as the above conditions are satisfied, the trigger member may be a single member or a plurality of members.

In the case of the aforementioned manual gun, a manual trigger is used as the drive unit. In such a case, the drive section has a trigger section having a trigger provided so as to be movable in the front-rear direction of the gun body, and a swing section that is swingably attached to the trigger section. The trigger part and the peristaltic part constitute a trigger member, It is desirable to adopt a configuration that moves along the guide portion inclined in the direction of releasing the engagement counterpart from the engagement portion in the vicinity of the retreat limit position as it is retracted by the trigger pulling operation. 2). With this configuration, only the swinging portion is inclined with respect to the retracting trigger portion, and the engaging counterpart can be smoothly detached from the engaging portion.

The trigger member is provided with a return spring that assists movement in the same direction when the viston moves forward. Thereby, the trigger member can be quickly returned to the original position. The return spring acts on the swinging portion constituting the trigger member, and can also be used to control the operation of the engaging portion and the engaging counterpart described later.

When the piston moves backward, biasing the trigger member in the direction in which the engaging portion and the engaging counterpart engage is a necessary structure for stable operation. As an urging means for that purpose, it is possible to have a pressure member provided in the magazine so as to protrude outward from the magazine by an elastic body provided in the magazine. ) The elastic body installed in the magazine is located at the position where the tip side pushes the bullet in the supply direction, and the base end side is supported by the inner wall of the magazine, etc., so the base end side uses the elastic force of the elastic body For this reason, a pressure member is provided at the corresponding part of the magazine so as to protrude outward from the magazine so that the elastic force of the elastic body is exerted on the pressure member. It is possible to urge the pressure member in the direction in which the engaging part and the mating part engage with each other without using the elastic body in the magazine, but use the elastic body built in the magazine. Is possible as described above, and the configuration can be rationalized.

In addition, when the magazine is removed from the gun body, the bullet feed path described above is used to prevent the bullets remaining in the bullet feed path that feeds the bullets in the magazine saddle to the mounting part of the gun body from falling out. Can be equipped with a stopper capable of appearing and retracting (invention of claim 4). Since the bullets that remain in the gun's main body are the cause of the remaining bullets, preventing the bullets remaining in the bullet feed path from spilling is a problem with the remaining bullets. Apart from that, the problems that can occur when the magazine is removed from the gun body can be solved by making minor modifications to the gun body.
