Simulated gun power suppression device

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for suppressing the launching power of a simulating gun in which a bullet is disposed on a jet path of a gas stream and emitted by a compressed air stream.

For the simulated guns such as air guns and air guns, the movement of the bullets fired in the first paragraph of the Law on the Holding of Guns and Swords is stipulated. According to this regulation, it can be understood that when using 6mm bullets, When the energy at a specific measurement point becomes greater than 3.5 J/cm2, it is regarded as a quasi-air gun. Therefore, an air gun that exceeds the above specified value is not manufactured. However, when several conditions overlap, there are cases where the specified value is temporarily exceeded. For example, the above problems may occur when used in high temperatures in midsummer.

Regardless of the temperature conditions, it is also possible to become a problem when using bullets other than those specified by the manufacturer. In this type of simulation gun, a bullet having a diameter of 6 mm as described above is used, which is called a BB bomb. As the BB bomb, a plastic molded product is sold by each manufacturer, but an example in which a metal ball flow having a ball diameter of 6 mm is used for a bullet is also reported. Therefore, if a combination of a weight bomb other than the commonly used plastic BB bomb, a high-temperature power source (CO2) other than a commonly used 134a gas, and the like, may be used in combination, The phenomenon of rising speed of the bullet.

In this way, when a metal ball having a mass larger than that of a plastic BB bomb is used as a bullet, it cannot be ignored for each manufacturing company. If you don't take some countermeasures, you may be able to let go of the illegal behavior without expectation. It is not a good thing for the industry. However, since it is an unanticipated situation, there has not been disclosed a technique for distinguishing or excluding metal bullets.

As a result of investigating the prior art, the invention of the air gun of Japanese Patent Publication No. 2009-14327 was discovered. The invention of the same specification has a configuration in which the automatic valve is automatically reduced and closed from the gas when the pressure and the flow rate of the compressed gas discharged from the gas accumulator to the inner barrel are within a predetermined value or more. The flow path to the inner barrel is released from the flow path, thereby adjusting the pressure and flow rate of the compressed gas discharged from the gas accumulator to the inner barrel. However, still There is a problem of complication caused by the addition of the automatic valve to the one member, and it cannot be concluded that the automatic valve does not close the gas discharge port or the like before the bullet is fired, and there is still a problem in practical use.

Patent Document 1: Japanese Patent Publication No. 2009-14327

The present invention has been made in view of the above problems, and an object thereof is to provide a power suppressing device for a simulated gun, which can prevent the movement energy of the emitted bullet from exceeding a prescribed value when using a bullet having a mass larger than that of a plastic BB bomb. Especially the most simple power suppression device for simulating guns. Further, another object of the present invention is to provide a power suppressing device for a simulated gun which can hardly reduce the kinetic energy generated by the BB bomb when mixing a plastic BB bomb and a bullet having a mass larger than that of a plastic BB bomb.

In order to solve the above problems, in the present invention, in a simulation gun in which a bullet is disposed on a jet path of a gas stream and is emitted by a compressed air stream, a gas flow leaking in a portion of the injection path or the injection path to leak a compressed gas stream is formed. The Department’s approach serves as a means of suppressing the launching power of bullets based on the quality of the bullet. The simulation gun to which the present invention can be applied is a simulation gun using a compressed air flow, and is a so-called air gun mainly using an air gun using air and a gas other than air. Therefore, in the present invention, the compressed gas flow is a general term for the flow of compressed air or a gas other than the compressed air.

In the construction of the simulated gun, the apparatus of the present invention is characterized by having a gas flow leak that causes the compressed gas stream to leak. The compressed airflow is sprayed on the BB and metal bullets at the same applied pressure, but the acceleration acting on the bullet follows the Newtonian equation of motion that is proportional to the force and inversely proportional to the mass of the bullet.

That is, a relatively light weight (less mass) bullet begins to move with relatively small motion energy, while a relatively heavy (high mass) bullet must start moving with relatively large motion energy. That is, for a relatively light BB bomb, the leak time of the airflow is shortened to emit, and the relatively heavy metal bullet is emitted, and a long airflow leak time is required. On the other hand, the amount of compressed airflow used to fire one round of bullets is fixed, and the power is suppressed corresponding to the amount of leakage. the amount.

As the apparatus of the present invention, a gas leakage portion is preferably formed by forming an injection path through which a compressed air current can pass or a small hole or a gap which is directly open to a portion of the injection path. In the case of the air leakage portion that is always open, the structure is simplified, and the time difference until the bullet is emitted is less than the manner in which the airflow is not leaked.

The airflow leakage portion is located upstream of the position on the injection path where the bullet is disposed, and is an always open flow path through which the compressed airflow can pass. This structure is a preferred embodiment of the present invention. However, it is also possible to adopt a method in which the air leakage portion is formed upstream from the position on the injection path where the bullet is disposed.

Since the present invention is configured as described above and functions, it is possible to achieve the effect of suppressing the power by the flow path which is always open, which is the most simple structure, that is, when a metal bullet such as a metal BB is used. It is also possible to prevent the movement of the bullet being fired beyond the specified value. Further, according to the present invention, it is possible to provide a power suppressing device for a simulated gun which can hardly reduce the exercise energy generated by the BB bomb when mixing a plastic BB bomb and a metal bullet having a mass larger than that of a plastic BB bomb.

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Fig. 1 shows a simulation gun 10 to which the power suppression device of the present invention is applied. As the simulation gun 10, an air gun using compressed air and an air gun using a gas other than air are mainly used. The example shown in Figures 1 to 6 is the case of an air gun.

The air gun uses a compressed gas as the compressed air flow, and its outline is explained, but the specific structure can be the same as that of the known air gun. The compressed gas is filled in the gas source 11, and the discharge valve 13 released from the control gas is discharged to the injection path 14 by the operation of the trigger 12, and is ejected to the bullet 15 of the loading portion disposed at the rear of the barrel 16. The injection path 14 through which the compressed gas to be discharged flows is equipped with a slide cylinder 17, and the bullet 15 supplied from the magazine 19 is disposed in the loading portion by sliding in the front-rear direction.

Although not directly related to the power suppressing device of the present invention, the valve device 18 provided inside the sliding cylinder 17 will be described. The valve device 18 temporarily closes the compressed airflow flowing out to the barrel side after the projectile is fired, leaving it inside the cylinder to retreat the piston 27 at the rear and the slider integrated therewith, thereby inducing a simulated recoil. The valve device 18 is configured to bias the coil spring disposed inside the biasing means 18a in the upstream direction of the gas flow, and the area of the opening portion 18b on the side surface is changed by the slider.

In the power suppressing device of the present invention, the airflow leaking portion 20 is located upstream of the position on the injection path where the bullets 15 are disposed, and is configured as a flow path that is always open through which the compressed airflow can pass. The position on the injection path in which the above-described bullet 15 is disposed is the loading portion at the rear of the barrel 16. An embodiment of the power suppressing device applied to the air gun will be described with reference to Figs. 2 to 6 . In addition, the arrows in the respective figures schematically show the flow directions of the compressed gas streams in the respective examples.

In the first example of the air force suppressing device for an air gun shown in Fig. 2, the air flow leaking portion 20 is configured as a small hole 21 of a flow path that is always open, and the small hole 21 is opened in one of the injection paths 14 through which the compressed airflow can pass. Part of the rear end of the barrel. In each example of the embodiment, loading Since the upper screw device 26 is provided on the portion, the small hole 21 serves as a cylindrical material that passes through the barrel 16 and the upper screw device, and causes the compressed airflow to leak outside the injection path.

In the second example of the power suppressing device for an air gun shown in Fig. 3, the airflow leaking portion 20 is configured such that the diameter of the barrel 16 which is a part of the injection path 14 through which the compressed airflow can pass is set as The diameter of the bullet 15 is one turn larger, and a gap 22 is formed around the bullet 15. Since it is the gap 22, it can be said that it is a flow path which is always open. In the case of the example 2, the upper-rotating device 26 provided in the loading portion is formed to be slightly long. The gap 22 of the example 2 causes the compressed air flow to leak around the bullet 15.

In the example 3 of the air force suppressing device for an air gun shown in Fig. 4, the air leakage portion 20 is configured as a small hole 23 of a flow path that is always open, and the small hole 23 serves as a part of the injection path 14 through which the compressed airflow can pass. The nozzle 17a is opened in the slide cylinder 17. In the case of the third example, the small hole 23 is provided at a position rearward of the loading portion as the structure penetrating the sliding cylinder nozzle 17a, and the structure for leaking the compressed airflow outside the injection path is the simplest in structure.

In the example 4 of the air force suppressing device for an air gun shown in Fig. 5, the air leakage portion 20 is configured as a small hole 24 of a flow path that is always open, and the small hole 24 serves as a part of the injection path 14 through which the compressed airflow can pass. It is provided in the main body portion of the slide cylinder 17. In the case of the example 4, the small hole 24 is provided in the back of the loading part and the front side of the piston 27 as the structure which penetrates the slide cylinder nozzle 17a. Therefore, this structure is structurally simple as a structure for leaking the compressed airflow to the outside of the injection path.

In the example 5 of the power suppressing device for an air gun shown in Fig. 6, the air leakage portion 20 is configured as a gap 25, and the gap 25 is provided at a rear end portion and a sliding portion of the barrel as a part of the injection path 14 through which the compressed airflow can pass. Between the cylinder nozzles 17a. Since it is the gap 25, it can also be said that it is an air leakage portion that is always open. The gap 25 of the example 5 can be set by adjusting the advancement position of the slide cylinder 17.

Further, as an example of the power suppressing device of the present invention, an air gun suitable for using compressed air will be described. Fig. 7 shows the basic structure of the air gun, equipped with a piston cylinder device 30 for compressing air as an alternative to the gas source of the air gun. The piston-cylinder unit 30 is composed of a piston 28 and a cylinder 29, and the air compressed by the operation of the piston 28 serves as a compressed air flow, and the firing mode of the piston 28 can be selected manually or electrically.

When the power suppressing device of the present invention is applied to the above air gun, the barrel is 16. The same components are denoted by the upper-rotation device 26 and the like, and detailed descriptions thereof will be omitted. Hereinafter, an embodiment of a power suppressing device applied to an air gun will be further described with reference to Figs. 8 to 13 .

In the example 1 of the power suppressing device for an air gun shown in Fig. 8, the airflow leaks. The portion 20 is configured as a small hole 31 of a flow path that is always open, and the small hole 31 is opened at a rear end portion of the barrel as a part of the injection path 14 through which the compressed airflow can pass. Since the upper screw device 26 is provided in the same manner as the example 1 of the air gun power suppressing device, the small hole 31 serves as a cylindrical material that passes through the barrel 16 and the upper screw device, and causes the compressed airflow to leak outside the injection path. Further, the present example 1 corresponds to the air gun example 1 (Fig. 2).

In the example 2 of the power suppressing device for an air gun shown in Fig. 9, the airflow leaks. The portion 20 is configured as a gap 32 by making the diameter of the barrel 16 which is a part of the injection path 14 through which the compressed airflow can pass, one turn larger than the diameter of the bullet 15. Since it is the gap 32, it can also be said that it is a flow path that is always open. In the case of the example 2, the upper rotation device 26 provided in the loading portion is formed to be slightly long. The gap 32 of the example 2 leaks the compressed air flow around the bullet 15. Further, the present example 2 corresponds to the air gun example 2 (Fig. 3).

In the example 3 of the power suppressing device for an air gun shown in Fig. 10, the air flow is leaked. The leak portion 20 is configured as a small hole 33 as a flow path that is always open, and the small hole 33 is opened in the nozzle 29a of the air gun cylinder 29 as a part of the injection path 14 through which the compressed airflow can pass. In the case of the third example, the small hole 33 is provided at a position rearward of the loading portion as the structure penetrating the sliding cylinder nozzle 29a. Therefore, the structure is the simplest to leak the compressed airflow to the outside of the injection path. . Further, the present example 3 corresponds to the air gun example 3 (fourth diagram).

In the example 4 of the power suppressing device for an air gun shown in Fig. 11, the airflow is exhausted. The drain portion 20 is configured as a small hole 34 of a flow path that is always open, and the small hole 34 is provided in a main portion of the slide cylinder 29 as a part of the injection path 14 through which the compressed airflow can pass. In the case of the example 4, the small hole 34 is provided in the rear of the loading portion and further forward than the forward limit of the piston 28 as the structure penetrating the sliding cylinder nozzle 29a. Therefore, the structure is simple in structure as a structure for leaking the compressed airflow to the outside of the injection path. Further, the present example 4 corresponds to the air gun example 4 (Fig. 5).

In the example 5 of the power suppressing device for an air gun shown in Fig. 12, the airflow leaking portion 20 is configured as a gap 35, and the gap 35 is provided in the jetting path 14 through which the compressed airflow can pass. A portion of the rear end portion of the barrel is between the slide cylinder nozzle 17a. Since it is the gap 25, it can also be said that it is an air leakage portion that is always open. Further, the gap 35 of the example 5 can be set by adjusting the advancement position of the slide cylinder 17. This example 5 corresponds to the air gun example 5 (Fig. 6).

In the example 6 of the power suppressing device for an air gun shown in Fig. 13, the airflow is exhausted. The drain portion 20 is configured as a gap 36 by making the outer peripheral diameter of the piston 28 smaller than the inner peripheral surface of the air gun cylinder 29 which is a portion of the injection path 14 through which the compressed airflow can pass. Since it is the gap 36, it can also be said that it is a flow path that is always open. In the case of Example 6, the compression capacity of the air is purposefully reduced.

In the example 7 of the power suppressing device for an air gun shown in Fig. 14, the air flow is leaked. The drain portion 20 is formed by providing a small hole 37 penetrating the piston in the piston 28, and the piston 28 slides on the inner peripheral surface of the air gun cylinder 29 as a part of the injection path 14 through which the compressed airflow can pass. Since it is the small hole 37, this is also a flow path that is always open. In the case of Example 7, it is the same as Example 5 in that the compression capacity of the air is purposefully lowered.

According to the invention thus constituted, the quality is greater in use than the plastic BB bomb In the case of metal bullets, it is also possible to suppress the power, so that the movement of the bullets emitted can exceed the specified value, so there is no danger of exerting unexpected power to cause safety hazards. Moreover, even if a plastic BB bomb is used and a metal bullet having a larger mass than the plastic BB bomb is used, the power of the BB bomb is hardly reduced, so that it can be regarded as a simulated gun having substantially the same power as the conventional power. Does not make users feel unhappy.
