Description

Safety device for simulated gun

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.

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

In order to solve the above-described problems, the present invention has a magazine that is detachably attached to a gun body, supplies bullets inside the magazine to the loading portion of the gun body, and compresses the bullets arranged in the loading portion. In a simulated gun having a piston device for injecting air, the piston is engaged with the piston-side engaging portion in order to retract the piston of the piston device in accordance with the launching operation in the driving portion, which is mounted on the gun body. And a trigger member having an engagement counterpart that moves the piston forward from the engagement, and the trigger member is movable in the forward and backward direction of the piston and is engaged from the engagement portion. Provided in the gun body so that it can move in the direction in which the mating part comes off, and the trigger member is provided with a return spring that assists movement in the same direction when the piston moves forward, and engages with the engagement part An urging member for the hand to urge the trigger member in a direction of engagement, in which took measures of using an elastic body that is installed in the magazine.
The safety device according to the present invention is configured to supply the bullet inside the magazine detachably attached to the gun body to the loading portion of the gun body. It is intended for a simulated gun in which a bullet remains and a piston device that is a function for injecting compressed air to the remaining bullet is alive. As the simulated gun that satisfies this condition, there is a manual gun for young people, which has a structure in which a piston is manually driven by pulling a trigger and compressed air is injected. However, for example, an electric gun is also an object of the present invention because a piston device that is a function for injecting compressed air to the remaining bullets may be alive. The simulated gun used in the present invention means a gun that is not intended for killing, compared to a gun intended for killing, that is, a real gun.
In the safety device according to the present invention, in order to retract the piston of the piston device with a firing operation in the drive unit, which is equipped on the gun body, the piston is engaged with the engagement portion and the engagement And a trigger member having an engaging counterpart for moving the piston forward. The trigger member is provided in the gun main body so as to be movable in a forward and backward direction of the piston and movable in a direction in which the engaging counterpart is removed from the engaging portion. In other words, the trigger member is a member that communicates the drive unit equipped in the gun body with the piston, and transmits the movement associated with the firing operation in the drive unit to the piston so that it moves backward. An engaging mating part is provided on the engaging part and the trigger member side. When the piston is retracted, the engaging part and the engaging mating part are engaged, and when the piston is advanced, the engaging part and the engaging mating part are Release the engagement. Therefore, the trigger member is required to have a structure provided in the gun body so that the trigger member can move in the forward and backward direction of the piston and can move in the direction in which the mating counterpart is removed from the engaging portion. As long as the above condition is 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 unit shall have a trigger part having a trigger provided so as to be movable in the front-rear direction of the gun body, and a swing part attached to the trigger part so as to be swingable. The trigger part and the swing part constitute a trigger member, and the swing part is swingable as it is retracted by an operation of pulling the trigger. It is desirable to adopt a configuration that moves along a guide portion that is inclined in a direction in which the engagement counterpart portion is released (the invention according to claim 2). With this configuration, only the swinging portion is inclined with respect to the retracting trigger portion, and the mating mating portion can be smoothly detached from the engaging portion.
For the trigger member, a return spring is provided to assist movement in the same direction when the piston moves forward. Thereby, the trigger member can be quickly returned to the original position. In addition, the said return spring acts on the rocking | swiveling part which comprises a trigger member, and can be utilized also in order to control the operation | movement of the engaging part and engagement partner part which are mentioned later.
When the piston moves backward, biasing the trigger member in the direction in which the engaging portion and the engaging counterpart are engaged is a necessary structure for stable operation. As an urging means for that purpose, it is possible to have a pressurizing member provided in the magazine so as to protrude outward from the magazine by an elastic body equipped in the magazine (the invention according to claim 3). The elastic body installed in the magazine is located at the position where the tip side pushes the bullet in the feeding direction, and the base end side is supported by the inner wall of the magazine, etc., so that the base end uses the elastic force of the elastic body Therefore, a pressure member is provided at a corresponding portion of the magazine so as to protrude outward from the magazine, and the elastic force of the elastic body is applied to the pressure member. It is possible to urge the pressure member in a direction in which the engaging portion and the engaging counterpart engage with each other without using the elastic body in the magazine, but it is also possible to use the elastic body built in the magazine. This 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 appears and disappears in order to prevent the bullets remaining in the bullet feed path that feeds bullets inside the magazine to the gun body loading part. Possible stoppers can be provided (invention of claim 4). Because the bullets remaining in the bullet loading part of the gun body cause the remaining bullets to be released, preventing the bullets remaining in the bullet feed path from spilling out is a problem with the remaining bullets firing. Alternatively, the problems that can occur with removing the magazine from the gun body can be solved by making minor modifications to the gun body side.

Reference numerals

45 and 46 denote members for holding the bullet 32 so that the bullet 32 does not flow into the barrel 29.
The simulated gun to which the safety device 10 according to the present invention constructed as described above is applied operates as shown in FIGS. (1) in FIG. 7 shows a state in which the magazine 33 is set on the gun body 11. At this time, the stopper 43 is pushed sideways, and the bullet 32 inside the magazine 33 passes through the bullet feed path 41A. Held in the loading section. On the other hand, in the magazine 33, the pressing member 40 is pushed up by the internal elastic body 36, so that the swinging portion 14 of the trigger member 15 moves upward to engage the engaging portion 27 and the engaging counterpart portion. 17 is in a state where it can be engaged. When the trigger 12 is pulled, the trigger member 15 is retracted and the engaging portion 27 and the engaging counterpart portion 17 are engaged ((2) in FIG. 7), the retraction of the piston 21 starts, and the trigger member 15 In the moving part 14, the guide roller 18 moves back the guide part 19, so that the engaging counterpart part 17 moves downward. When the swinging member 14 that moves along the inclined guide portion 19 reaches the vicinity of the retreat limit position, the engagement counterpart portion 17 is detached from the engagement portion 27, and the free piston 21 is elastically released. Pressurized by the means 25 and advances instantaneously, the air in the cylinder 23 is compressed and ejected from the nozzle 24, whereby the bullet 32 in the bullet loading part is fired ((3) in FIG. 7).
When the trigger 12 is released, the trigger member 15 moves forward by the return spring 16 and moves in the original position direction, and the engaging counterpart 17 of the swinging portion 14 moves the inclined guide portion 19 ((1) in FIG. 8). In the process of moving forward, the front upper portion 17a of the engagement counterpart 17 gets over the rear lower portion 27a of the engagement portion 27 and becomes engaged, and maintains the engaged state and returns to the original position (FIG. 8). (2)).
When the magazine 33 is removed from the gun body 11, the pressing member 40 is not biased by the elastic body 36 inside the magazine and cannot be pushed up. Therefore, since the guide roller 18 of the swinging portion 14 of the trigger member 15 is in the state of falling into the recess 19a in front of the guide portion 19, the engaging portion 27 and the engaging counterpart portion 17 are not engaged. ((1) in FIG. 9). Therefore, even if the trigger 12 is pulled back by pulling the trigger 12, the piston 21 does not move back ((2) in FIG. 9) because the engaging portion 27 and the engaging counterpart portion 17 are not engaged, so that Even if bullets 32 are loaded, they are not fired. Further, when the magazine 33 is removed from the gun body 11, the stopper 43 is rotated by the spring 44 to stop the bullet 32, so that even if the bullet 32 remains in the bullet feed path 41A, it does not fall out.
Since the present invention is constructed and operates as described above, in a gun having a magazine detachably attached to the gun body, the piston cannot be retracted after the magazine is removed from the gun body, and a bullet is placed in the gun body. Even if it remains, the risk of fire can be prevented. Further, according to the present invention, it is possible to provide a safety device for a simulated gun that can reliably prevent the gun from being accidentally discharged due to carelessness after the magazine is removed from the gun body.
