Description

  The present invention relates to a crime prevention or disaster prevention marking device, and more particularly, when a crime or disaster is encountered, the crime person or himself is marked so that the crime person or himself can be easily seen at night, thereby preventing crime or disaster prevention. It relates to a crime prevention or disaster prevention marking device.

  As a crime prevention or disaster prevention marking device, there is a device that encloses colored marking liquid and high-pressure air in a container and injects the marking liquid toward the criminal with the pressure of high-pressure air when a crime is encountered ( See Patent Document 1 below).

  On the other hand, long afterglow phosphors that store light energy received from sunlight, illumination light, etc., and release the light energy stored when it becomes dark are known. Such a long persistence phosphor may be applied to a display object or the like so that a display object or the like showing an evacuation route can be visually recognized even in a dark place in the event of a power failure accident at night. In recent years, development of a long afterglow phosphor capable of continuing to emit light for a sufficiently long time after the light irradiation has been stopped has progressed (see Patent Document 2 below).

Utility Model Registration No. 3008571 Japanese Patent Laid-Open No. 2002-20744

  By the way, in the crime prevention marking device disclosed in Patent Document 1, even if a crime or disaster is encountered and a colored liquid is sprayed on the criminal or himself, the criminal or himself can be seen from a distance in the dark such as at night. There was a problem that it was difficult to obtain, the criminal rubbed with coloring or the possibility of being rescued, and the crime prevention effect or the disaster prevention effect was insufficient.

  The present invention has been made in view of the above problems, and when a crime or disaster is encountered, a mark that can be visually recognized even in the dark can be attached to the criminal or himself, and has a large crime prevention effect or disaster prevention effect. It is an object to provide an apparatus.

To solve the above problems, the invention according to claim 1, comprising a tank filled with marking substance, a discharge port for releasing the previous SL marking material to the outside from the tank, and a cap for closing the outlet aperture security Or in the disaster prevention marking device, the crime prevention or disaster prevention marking device has a buzzer switch, a buzzer that is supplied with power through the buzzer switch, a light source that irradiates the inside of the tank, and an opening that accommodates the tank. A long-afterglow phosphor dispersed in the marking material, and the tank has a piston portion that slides in the axial direction to pressurize the marking material. When the piston portion is viewed through the opening and the piston portion is pushed with a finger, the marking substance is removed from the cap and released to the outside. While being characterized in that the buzzer switch is ON from OFF.

The crime prevention or disaster prevention marking device of the invention according to claim 1 is easy to insert into the pocket because the main body is just large enough to fit in the palm. According to the crime prevention or disaster prevention marking device of the present invention when encountering crimes such as robberies, violent acts, molesters, etc. It can be released from the outlet and attached to the criminal, and at the same time, a buzzer can be sounded, and the criminal can be escaped by flashing the long afterglow phosphor in the marking substance and the buzzer sound . In addition, the long-afterglow phosphor emits light so that the criminal can be visually recognized even in the dark, and in some cases, the criminal's face can be visually recognized, and the criminal can be easily tracked and arrested. Furthermore, the long afterglow phosphor is difficult to penetrate through clothes and the like, and emits light semipermanently when receiving light, so it is also useful as evidence of a crime. In addition, when a disaster occurs in a mountain or the sea, the victim can easily be found by the rescue team even at night by attaching a marking substance to himself or a nearby object.

  In the crime prevention or disaster prevention marking device of the present invention, a long afterglow phosphor powder is dispersed in a marking substance that marks the criminal or himself, and the criminal is detected by the long afterglow phosphor attached to the criminal even in the dark. In addition to being jealous, it ensures that the criminal or yourself can be seen.

  Hereinafter, an embodiment of the crime prevention or disaster prevention marking device of the present invention will be described based on the drawings. FIG. 1 is a side view of the crime prevention or disaster prevention marking apparatus. FIG. 2 is a front view of the crime prevention or disaster prevention marking device.

  This crime prevention or disaster prevention marking apparatus has an oval and hollow main body 100 that is just as large as it can fit in a palm and has a thickness that can be easily inserted into a pocket.

  A circular opening 16 is provided on both side surfaces of the front half of the main body 100, and a cylindrical tank 10 is accommodated in the position of the opening 16. The tank 10 is filled with a long persistence phosphor powder and a solvent (dispersion medium) in which a colorant is dispersed as the marking substance 18. In this solvent, ethanol alone, acetone alone, solvent evaporation type thermoplastic resin 20-40% by weight, or a solution in which an oligomer is dissolved in an organic solvent such as ethanol or acetone can maintain the long afterglow phosphor stably for a long period of time. So it is suitable.

  The diameter of the long afterglow phosphor is preferably about 0.5 to 5.0 μm, particularly about 1.0 μm. The reason for this is that if the long persistence phosphor has a diameter of 0.5 μm or less, the light emission duration after the light irradiation is interrupted is shortened, and if the long persistence phosphor has a diameter of 5.0 μm or more, it is long. This is because the afterglow phosphor is difficult to uniformly disperse in the solvent. Since such a long afterglow phosphor and the colorant itself are well known, further explanation is omitted.

  At the front end of the main body 100, a nozzle 12 serving as a marking substance discharge port communicating with the tank 10 is provided. The tip of the nozzle 12 is closed with a cap 14, and the cap 14 is detached when a pressure exceeding a predetermined level is applied from the marking material 18. In order to attach the cap 14 to the nozzle 12, anything such as adhesion, welding, or an engaging claw may be used. Of course, instead of the cap 14, a lid integral with the nozzle 12 may be provided at the outlet of the nozzle 12, and the lid may be broken when a pressure of a predetermined level or more is applied from the marking substance 18.

The tank 10 includes a cylindrical portion 10a, a bottom portion 10b integrated with the cylindrical portion 10a, and a piston portion 10c that is a lid for closing the opening side of the cylindrical portion 10. Since this piston portion 10c is slidable with respect to the cylindrical portion 10a and is looking through the opening 16 of the main body 100 , when the bottom portion 10b and the piston portion 10c are sandwiched between fingers and pressed strongly, the piston portion 10 c moves in the cylindrical portion 10 a and feeds the marking substance 18 accommodated in the tank 10 to the nozzle 12. Then, the cap 14 is detached from the nozzle 12 by the pressure of the marking material 18, and the marking material 18 is jetted from the nozzle 12 in a water gun type. However, the cap 14 is attached to the nozzle 12 with such a strength that the cap 14 does not come off the nozzle 12 if the piston portion 10c is accidentally pushed.

  The cylindrical portion 10 a of the tank 10 is made of a material that transmits ultraviolet rays, and ultraviolet rays emitted from an ultraviolet LED (light emitting diode) 24 that is a light source for irradiating a long afterglow phosphor, which will be described later, enter the tank 10. It is like that. The bottom portion 10b and the piston portion 10c are opaque so that ultraviolet rays emitted from the ultraviolet LED 24 do not leak outside.

  The latter half of the inside of the main body 100 is an electrical component storage unit that incorporates a battery 22, an ultraviolet LED 24, an illumination light source (LED, miniature bulb, etc.) 26, a buzzer 28, and the like.

  The ultraviolet LED 24 is always supplied with power from the battery 22 and is lit, and supplies light energy to the long afterglow phosphor in the marking substance 18 in the tank 10. Since the ultraviolet LED 24 consumes less power, the button LED can keep the ultraviolet LED 24 lit for about 2-3 years. Of course, a visible light LED may be used instead of the ultraviolet LED 24, and a light source such as the ultraviolet LED 24 or the visible light LED may be installed in the tank 10 instead of outside the tank 10. In this case, an opaque material can be used for the cylindrical portion 10 a of the tank 10.

  Since the illumination light source 26 is supplied with power from the battery 22 via the illumination switch 30, this crime prevention or disaster prevention marking device can also be used as an illumination tool. The illumination light source 26 is also used to check the remaining amount of the battery 22 by turning on the illumination switch 30 when appropriate. When the battery 22 becomes empty, the long afterglow phosphor does not emit light in the dark, so the battery 22 is replaced with a new one.

Power is supplied to the buzzer 28 from the battery 22 via a buzzer switch (not shown) that is linked with the movement of the piston portion 10 c of the tank 10. When the piston portion 10c is strongly pressed, the buzzer switch is switched from normal OFF to ON, and the buzzer 28 sounds.

  According to the crime prevention or disaster prevention marking device of the present embodiment, when a crime such as a violent act or a molester is encountered, the nozzle 12 is directed toward the criminal and the bottom portion 10b of the tank 10 and the piston portion 10c are sandwiched between fingers and pressed with full force. The marking substance 18 in which the long afterglow phosphor is dispersed is sprayed on the criminal to attach the colored mark and the long afterglow phosphor to the criminal, and the buzzer 28 can be sounded. Thus, since the criminal glares at the daytime with the coloring and the sound of the buzzer 28 and at night the light of the long afterglow phosphor and the sound of the buzzer 28, the criminal can escape from the criminal. Further, even in the dark, the long afterglow phosphor emits light so that the criminal can be visually recognized, and in some cases, the criminal's face can be visually recognized, and the criminal can be easily tracked and arrested. Furthermore, the long afterglow phosphor is difficult to penetrate through clothes and the like, and emits light semipermanently when receiving light, so it is also useful as evidence of a crime.

  Also, when a dangerous animal or the like is encountered, the crime prevention or disaster prevention marking device of the present embodiment can be used, and in this case also, the dangerous animal can be easily controlled or captured. Furthermore, according to the crime prevention or disaster prevention marking device of the present embodiment, when the person is sprayed with the marking substance 18 when he / she encounters in the mountains or the sea, it is also conspicuous both day and night so that it is easy to be rescued.

  The present invention is not limited to the above embodiment, and various modifications can be made as follows, for example.

  The crime prevention or disaster prevention marking device of the present invention may be modified such that a water spray gun is remodeled to inject a marking substance in which a long persistence phosphor powder is dispersed. If a water gun function is provided, a suitable shape such as a key holder type or a pen type can be selected.

  In the above-described embodiment, the marking material 18 is injected by the water gun method. However, as shown in FIG. 3, the high-pressure air 52 and the marking material 18 are accommodated in the tank 50, and the marking material 18 is moved by the pressure of the high-pressure air 52. You may make it inject. Instead of the high-pressure air 52, the marking substance 18 may be injected by a piston pressed by a spring. In this case, when the tank 50 is enlarged and the security sensor 54 such as a human sensor or a security camera detects that the criminal 58 has approached the crime prevention object 56 such as a safe, a warning is notified to the security guard and the valve 60 at the same time. By automatically injecting the opening marking material 18 from the discharge port such as the nozzle 62 toward the criminal 58, crime prevention in a specific area can be performed unattended.

  The marking substance 18 may be dispersed with a substance that emits a strong odor. In this case, the culprit can be repelled even if it smells, and the criminal can be easily tracked and identified by a police dog at a later date.

  The marking substance 18 may be a paste obtained by dispersing a long persistence phosphor powder and a suitable filler (filler) in an organic solvent. By making a paste in this way, it is easy to draw characters and symbols, and when it is lost in the mountains or the sea, it becomes easier to notify the distress by the characters and symbols. If you write a symbol on the collar of a pet, such as a dog or cat, it will be easier to find it at night when your pet gets lost, and it will be easy to see if it is your pet.

  As a dispersion medium for the marking substance, an organic solvent such as ethanol or acetone is used in the above-described embodiment for the purpose of stabilizing the long persistence phosphor, but is not limited thereto. For example, a long afterglow phosphor may be dispersed in a solution in which a thermoplastic resin or oligomer soluble in oil or an organic solvent is dissolved in an organic solvent. In this case, the long afterglow phosphor is difficult to peel off, which is excellent as evidence of crime. The aqueous solution of the long afterglow phosphor powder undergoes a chemical change with water, and the fluorescence effect is lost in 1 to 2 weeks. Therefore, when the long afterglow phosphor powder is coated or microencapsulated, A long afterglow phosphor does not cause a chemical change in inexpensive and safe water or an appropriate organic solvent as a dispersion medium, and is kept stable for a long period of time.

  The marking substance 18 is not limited to a liquid or paste. For example, a long afterglow phosphor powder and a colorant dispersed in a gas such as air may be used. In particular, when air is used, it becomes extremely cheap and safe.

  As shown in FIG. 4, the marking substance 18 may be given a binary code number depending on the presence or absence of a plurality of trace components A, B, C, D, and the like. Due to the presence of these trace components, the code number read from the marking material left in the user's crime prevention or disaster prevention marking device and the code number read from the marking material attached to the suspect are collated, and the criminal later It becomes easy to specify.

  The crime prevention or disaster prevention marking device of the present invention can be widely used not only for crime prevention of individuals and security guards but also for crime prevention of banks, shops, offices, factories, etc. that are unattended at night by being linked with security cameras and human sensors. . In addition, the crime prevention or disaster prevention marking device of the present invention can notify the user's position when encountering a disaster such as an earthquake or the like, and is effective for disaster prevention.
