Abstract

<P>PROBLEM TO BE SOLVED: To provide a self-defense instrument easy to operate and having excellent portability. <P>SOLUTION: The self-defense instrument has: a cylindrical container 1 closed at one end; a bag-like member 6 disposed in the container 1 and filled with liquid 7 against ruffians; ejection means 9-11 provided at one end of the cylindrical container 1 and having powder or the like; and a rupture means 3 provided at the other end of the cylindrical container 1, pointing its sharp tip part inward to rupture the bag-like member 6. Sufficient ejection pressure is generated even with a small amount of powder, but the container filled with the liquid against a ruffian requires strength enough to withstand an explosion, and in view of the case where the liquid against ruffians cannot be applied to the ruffian as it is, the rupture means for rupturing the bag-like member when passing through is newly provided to positively jet the internal liquid even if adopting a member with sufficient strength as the container filled with the liquid against a ruffian. As a result, stability in storage and at the explosion of powder is improved with the bag-like member with high strength, and the liquid against the ruffian is positively applied to the ruffian. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a self-protection device which is excellent in portability and easy to operate.

  In recent years, violent incidents by suspicious individuals have occurred frequently. Conventional general self-defense devices include: (i) a device that issues an alarm in the event of an emergency, a device that attaches paint to the other party, a spray that sprays tears, etc., (ii) a handgun, and (iii) a stun gun (long A device that can transmit power even at a distance), a device that can give an ultrasonic wave with a spot, a device that uses GPS or the like to perform warning and position detection using position information, and (iv) a piercing.

  However, the devices listed in (i) may not be expected to be effective immediately, and the handguns listed in (ii) are not allowed to be possessed for self-defense purposes in Japan. There are inconveniences such as the possibility of giving serious troubles, the devices listed in (iii) are expensive, and the devices listed in (iv) are inconvenient to carry.

  Considering an ideal device as a self-protection device, it is desirable that it is convenient in form, easy to operate and reliable in effect, and does not cause undue damage to thieves.

  The present invention has been made in view of the above circumstances, and an object to be solved is to provide a self-protecting device that is easy to operate and excellent in portability.

Means for Solving the Problems and Effects of the Invention

  As a result of intensive studies by the present inventors for the purpose of solving the above-mentioned problems, the following invention has been completed by focusing on and improving the spray for spraying the tear agent. That is, the self-protection device of the present invention includes a cylindrical container having one end closed, a bag-like member disposed in the cylindrical container and filled with a liquid for anti-crime, and the cylindrical container. An injection means provided with the explosive for firing the bag-like member and an ignition means for igniting the explosive; and a sharp tip at the other end in the cylindrical container And breaking means for breaking the bag-like member when the bag-like member passes therethrough.

  In other words, the spray that sprays liquid for anti-terrorism such as tears is excellent in portability, but due to the structure of spraying liquid, it may be possible that the liquid for anti-terrorism cannot be directed in the intended direction depending on the wind direction, etc. In such a case, the liquid may flow backward due to wind, etc., and there is a possibility that the person who uses the self-defense device may be concerned.

  Here, it is conceivable to simply increase the pressure of the spray, but it is difficult to handle high-pressure gas, and sufficient pressure cannot always be applied due to legal problems.

  Therefore, in the present invention, as a means for injecting and injecting liquid, a mechanism for injecting anti-terrorist liquid by utilizing explosion caused by explosives has been developed. This is because a small amount of explosive can generate a sufficient injection pressure. However, since gunpowder is excellent in shooting power, containers filled with anti-terrorist liquids need to have high strength that can withstand the explosion of gunpowder. The case where it was not possible was considered.

  Therefore, even if a bag-shaped member having sufficient strength is used as a container filled with anti-terrorist liquid, the bag-shaped member breaks when the bag-shaped member passes so that the liquid can be reliably injected. We decided to provide a new means. As a result, it is possible to improve stability during storage or explosive explosives using a bag-like member having high strength, and it is possible to cause the anti-terrorist liquid to act on the thief reliably.

  In other words, the liquid for anti-crime can be stably held by the bag-like member having high strength until it is injected by the explosion of the explosive, and then the injected bag-like member is surely broken by the breaking means. It is possible to make a liquid for anti-criminals act on thieves.

  The ignition means includes a rubbing portion and an ignition portion mainly composed of a chemical ignited by rubbing between the rubbing portion, and at least one of the ignition portion and the rubbing portion is moved to rub between the two. It is possible to adopt a means of igniting.

  Here, as a means for moving at least one of the ignition part and the rubbing part, a string-like member having one end connected to either one and the other end pulled out to the outside of the cylindrical container is adopted. Is desirable.

  In addition, it is preferable that the anti-crime liquid is selected from an instantaneous adhesive and a tear solution.

  Further, it is desirable that a buffer member for reducing the impact of the explosive explosion is interposed between the explosive and the bag-shaped member. Moreover, it is desirable that the other end of the cylindrical container is sealed.

  Furthermore, the injection means may be composed of an elastic body held in a compressed state and a release means for releasing the elastic body from the compressed state, instead of the combination of the explosive and the ignition means. By releasing the elastic body such as a spring from the compressed state, the bag-like member can be injected at a high speed.

  The self-protection device of the present invention will be described in detail below. The personal protective equipment of this embodiment has a cylindrical container, a bag-like member, injection means, and other necessary means. The cylindrical member is a cylindrical member. The cylindrical member is sufficient if it can withstand the stress during normal storage or when the bag-like member is injected by the injection means. The cylindrical member is preferably a member whose one end is closed. By closing, the propulsive force of the bag-like member due to the explosive explosive described later can be increased.

  The bag-shaped member is a member that is filled with a liquid for anti-terrorism. Examples of anti-tangle liquids include instant adhesives and tears. The instant adhesive is stable for a long period of time under light-shielded, low-temperature, low-humidity conditions, and after adhering to a thief, touching another object causes it to adhere to another object and reduce its ability to act. In addition, by attaching to the face, it becomes impossible to open the eyes and to act. Instant adhesives have low toxicity, so there are almost no side effects.

  Teardrops can be stimulated by adhering to mucous membranes such as the eyes and mouth and skin, and can help neutralize thugs. As the tearing agent, general materials such as CR gas, CS gas, CN gas and the like can be adopted. The bag-like member needs to be strong enough to withstand the stress at the time of injection by the injection means described later. In addition, it is desired that the liquid for anti-crime filled inside is chemically and physically stable. In order to improve the stability of anti-liquid for filling inside, it is desirable to provide light shielding properties, moisture barrier properties, and the like.

  The injection means has explosives and ignition means. Although it does not specifically limit as an explosive, General things, such as a black explosive and a smokeless explosive, can be employ | adopted. The ignition means is not particularly limited as long as it can explode explosives. For example, like a match, a combination of potassium chlorate or sulfur and red phosphorus or antimony sulfide is adopted and ignited by rubbing between the two. As a mechanism for rubbing between the two, a mechanism in which one end of a string-like member is connected to one member and the other end of the string-like member is pulled out of the cylindrical member can be employed. The ignition means ignites by pulling the other end of the string-like member pulled out to the outside. Explosives ignite and explode when ignited from ignition means.

  Here, the injection means can be composed of an elastic body in a compressed state and a means for releasing the elastic body from the compressed state, instead of the combination of explosives and ignition means. That is, the bag-like member is injected from the cylindrical member using energy that releases an elastic body such as a spring from a compressed state.

  The breaking means is means for breaking the bag-like member injected by the injection means in order to spray the anti-crime liquid filled inside the bag-like member. The breaking means has a sharp tip, and the tip is arranged inside the cylindrical member so as to face the inside. The tip portion is stabbed into a bag-like member passing through the cylindrical member and broken, thereby spraying anti-crime liquid filled therein. For example, a thin blade with a sharp tip such as a razor or a cutter blade can be exemplified.

  Examples of other means include a buffer member provided between the injection means and the bag-like member. The buffer member is a member that prevents the bag-like member from being torn by the impact of the explosive explosion. For example, a sponge-like member can be exemplified. Moreover, it is desirable that the other end of the cylindrical member is sealed. For example, by sealing with a sponge-like member, the breaking means and the bag-like member can be protected during storage. In particular, by providing protective means such as a sponge-like member between the breaking means and the bag-like member, it is possible to prevent the bag-like member from being broken due to unexpected contact of the bag-like member with the breaking means.

  Hereinafter, the self-protection device of the present invention will be described in more detail based on examples. As shown in FIG. 1, the self-protection device of the present embodiment includes a cylindrical member 1, a bag-like member 6, explosives 9 and ignition means 10 to 14 as injection means, a breaking means 3, and a closing means 4. And the buffer member 8.

  One end of the cylindrical member 1 is closed by the covering means 2. The covering means 2 is a member that closes and reinforces one end of the cylindrical member 1. The bag-like member 6 is formed by connecting one end portions 5 of a cylindrical bag, and is filled with an instantaneous adhesive (high viscosity type). The knot portion 5 is disposed so as to face the one end side of the tubular member 1.

  The gunpowder 9 employs black gunpowder. The ignition means is composed of a combination of sulfur powder 10 and antimony sulfide 11, and a member coated with antimony sulfide 11 is fixed to one end of a string-like member 13. When the string-like member 13 is pulled, the ignition means 10 and 11 are rubbed and ignited. A guide portion 12 having a guide through which the string-like member 13 passes is disposed at one end portion of the cylindrical member. A tag 14 is attached to the other end of the string-like member 13 so that the string-like member 13 can be easily pulled.

  The breaking means 3 is a member having a sharp tip disposed at the other end of the cylindrical member 1. The breaking means 3 is arranged at the other end portion of the cylindrical member 1 so that the tip end faces inward. The other end of the cylindrical member 1 is filled with a closing means 4. The closing means 4 is composed of a sponge-like member. At the end of the cylindrical member 1, a closing means 4 made of a sponge-like member having a size substantially corresponding to the inner diameter of the cylindrical member 1 is adopted, and from there to the bag-like member 6, a fine sponge-like member is used. The closing means 4 is adopted. By making it finer, the injection of the bag-like member 6 is less disturbed. Further, a buffer member 8 is interposed between the explosive 9 and the bag-like member 6.

  Since the self-protection device of the present embodiment has the above-described configuration, the following effects are exhibited. In the event of an emergency such as encountering a thief in a town or the like, the tubular member 1 is fixed with one hand and the string-like member 13 is pulled with the other hand. Here, the string-like member 13 is pulled in a state in which the tip (the other end) of the cylindrical member 1 is directed to a target portion (for example, a thief's face).

  Then, the ignition means 10 and 11 are rubbed and ignited, and the gunpowder 9 ignites and explodes. The buffer member 8 is pushed out by the power of the explosion, and then the bag-like member 6 is injected from the other end of the cylindrical member 1. At that time, when the bag-shaped member 6 passes through the portion where the breaking means 3 is disposed, the instantaneous adhesive 7 that is cut by the breaking means 3 and filled inside the bag-shaped member 6 is exposed to the outside. It will erupt. Here, the exposed instantaneous adhesive 7 flies as it is in a target direction toward the other end of the cylindrical member 1 and hits a target (such as a thief's face).

  Here, since the gunpowder is employed for the injection of the bag-like member 6, the means for injection can be made relatively smaller than the spray or the like. Therefore, it succeeded in miniaturizing the whole instrument. Moreover, since sufficient strength is imparted to the bag-like member, it can be stably carried during normal times.

It is the cross-sectional schematic of the self-defense instrument of an Example.
