Description

  The present invention relates to a marking tool using a phosphorescent substance.

  Guide lights indicating evacuation routes are used in case of emergency such as a power failure. For example, in the guide light described in Patent Document 1, a phosphorescent substance that absorbs (stores) light in an environment with light and emits (emits light) stored in an environment without light is used as a light source. Thereby, the guide light can be turned on even during a power failure when the light source does not operate.

  However, in the event of a disaster, the above-mentioned guide lights are not always provided in front of firefighters and the like for fire fighting and rescue. Therefore, when heading to a place where there is no light at night, it is desirable to attach a luminescent mark for indicating an evacuation route (retreat) for safety.

  If the phosphorescent material is transported and dispersed in the entry path, light emission for a certain time can be obtained. However, the phosphorescent material starts to emit light from the end of light reception, and the amount of light decreases with time. If a phosphorescent material is transported from a fire department or the like, it emits light before reaching the fire extinguishing or rescue site, reducing the amount of light. That is, the substantial light emission time is shortened, and the time devoted to fire fighting and rescue is also shortened.

  Also, marking by spraying is limited to the floor surface. Sometimes you want to mark on the wall. Further, when information is transmitted according to the shape of the mark, it is not easy to form the shape.

  Examples of the present invention will be described below.

  In FIG. 1, the internal structure of the marking tool 1 which concerns on a present Example is shown. The marking tool 1 uses a phosphorescent substance as a marking material, and includes a container body 10, a light emitting unit 20, and a nozzle unit 30.

  The container body 10 is a container that accommodates a marking material (a marking liquid 40 described later). The container main body 10 is formed including a body portion 11, a bottom portion 12, and a head portion 13 using a metal such as steel.

  The trunk portion 11 is located at the center of the container body 10. The trunk | drum 11 has the space 11a inside, and encloses the marking liquid 40 and the propellant 41 in it.

  In the present embodiment, the marking liquid 40 is configured by mixing a phosphorescent substance powder with a translucent liquid. A phosphorescent substance is a substance having the ability to repeat light absorption (light storage) and emission (light emission) of the stored light. Phosphorescent substances store visible light with a wavelength of 450 μm or less (yellow-green, blue-green, red, red-orange, blue, bluish purple, etc.) and emit light for several minutes (the amount of light emitted is about one-half). Decay time), with an afterglow time of 1000 minutes or more.

  The powder of the phosphorescent substance may be configured to include at least two phosphorescent substance powders of a phosphorescent substance having a short emission time and a phosphorescent substance having a long emission time. As a result, after the phosphorescence, the phosphorescent substance powder, which has a short emission time, emits strong light, and after the amount of emission is attenuated, the phosphorescent substance powder, which has a long emission time, emits light. It becomes possible. Here, for example, a phosphorescent material that accumulates green or near-green light may be employed as the phosphorescent material having a short emission time. When used at a fire site, the light can be visually recognized even in a situation where the flame is still rising immediately before use and before extinguishing.

  The translucent liquid is a liquid that mixes a powder of a phosphorescent substance and transmits light, and includes, for example, water as a main component and a water-soluble adhesive liquid as a subcomponent. Due to the translucency of water, as will be described later, the light emitted from the light emitting section 20 can be passed through the marking liquid 40 to illuminate the powder of the phosphorescent substance constituting the light. The adhesive liquid is widely known as “spray paste”, for example. Thereby, when the translucent liquid has adhesiveness and the marking liquid is sprayed onto the object to be marked, the phosphorescent substance powder can be adhered to the object to be marked due to the adhesiveness of the translucent liquid. That is, the shape at the time of injection is maintained for a long time, and information can be transmitted by the shape. Moreover, marking on the wall surface can be easily performed.

  The propellant 41 is used to configure the marking tool 1 as an aerosol spray by applying pressure to the marking liquid 40 and spraying it out of the marking tool 1 through the nozzle portion 30. As the propellant 41, for example, nonflammable carbon dioxide gas or nitrogen gas can be employed. Accordingly, the marking liquid 40 can be safely injected by the propellant 41 even in an environment including fire such as a fire site.

  The bottom 12 is provided on the bottom of the container body 10. The bottom part 12 has the space 12a inside, and accommodates the light emission part 20 in it. The bottom portion 12 has a partition wall 12b made of a translucent member such as glass, for example, and thereby separates the space 11a formed by the body portion 11 from the space 12a formed by the bottom portion 12.

  The head 13 is provided on the upper side of the container body 10. The head portion 13 has a support plate 13 a fixed between the head portion 13 and the body portion 11, and supports the nozzle portion 30 by the upper portion of the head portion 13 together with the support plate 13 a.

  The light emitting unit 20 is a device that emits light into the container body 10, and includes a power source 21 and a light emitter 22.

  The power source 21 is for supplying power to the light emitter 22, and a rechargeable power source is adopted in this embodiment. Before use, the power source 21 is charged by connecting the base end of the power cord 23 to the power source 21 through the opening 12c provided on the bottom surface of the bottom portion 12 and connecting the tip end to an external power source. Thereby, the light emitter 22 is actuated by the charged power source 21 to emit light into the container body 10 and can be stored in the phosphorescent substance powder of the marking liquid 40. At the time of use, as shown in FIG. 2, the power cord 23 is removed from the power source 21 and the marking tool 1 is carried. Since the luminous time of the phosphorescent material is finite, the power source is charged until just before use, and the phosphorescent material is accumulated until the marking liquid 40 is ejected. Long light emission time can be obtained.

  The light emitter 22 is a light source that receives electrodes from the power source 21 and illuminates the phosphorescent substance of the marking liquid 40. As the light emitter 22, for example, an LED that emits light corresponding to the color (wavelength) of light stored in the phosphorescent substance or white light can be employed. The light emitter 22 is provided on the upper surface of the light emitting unit 20, and emits light from the bottom 12 of the container body 10 into the space 11 a of the container body 10 through the translucent partition wall 12 b. Thereby, the light of the phosphorescent substance of the marking liquid in the container main body 10, particularly the powder of the phosphorescent substance of the marking liquid that settles on the bottom of the container main body 10 can be illuminated.

  Here, the light emitting surface of the light emitter 22 is often a flat surface, but may have another shape. For example, as an irregular shape protruding in the thickness direction of the phosphorescent material, light can be illuminated toward a location away from the light emitter of the thick phosphorescent material. A light guide can also be provided from the light emitting surface toward the phosphorescent material.

  The nozzle unit 30 is a member that ejects the marking liquid 40 and includes a tube 31 and an ejection button 32.

  The tube 31 is a tubular member configured using a flexible member such as resin, and the distal end thereof is positioned below the space 11 a of the trunk portion 11 and the proximal end is fixed by the head 13. .

  The injection button 32 is a member for injecting the marking liquid 40, and has an actuator and a valve (both not shown) therein. The injection button 32 is fixed to the proximal end of the tube 31 through a valve, and is displaced by pushing it downward using a finger, so that the valve is opened and the marking liquid 40 passes through the tube 31 and the nozzle of the injection button 32. Is injected from. When the finger is released from the injection button, the valve is closed by being biased by the actuator and returned to the original position, and the injection of the marking liquid 40 is stopped.

  As described above in detail, the marking tool 1 according to the present embodiment includes a container body 10 that contains a marking liquid 40 that is configured by mixing a phosphorescent substance powder with a translucent liquid, A light emitter 22 that emits light and a power source 21 that supplies power to the light emitting unit 20 are provided. Power is supplied to the light emitter 22 by the power source 21 and light is emitted into the container body 10 by the light emitter 22, thereby storing the phosphorescent substance powder constituting the marking liquid 40 accommodated in the container body 10. Can do.

  Moreover, the marking tool 1 according to the present embodiment further includes a nozzle portion 30 that ejects the marking liquid 40. By injecting the marking liquid 40 by the nozzle part 30, marking can be performed with the marking liquid.

  In FIG. 3, the internal structure of the marking tool 2 which concerns on a modification is shown. In addition, while attaching | subjecting the same code | symbol about the part which is the same as or corresponding to the above-mentioned marking tool 1, the detailed description is abbreviate | omitted. The marking tool 2 differs in the structure of the light emission part 20 with respect to the above-mentioned marking tool 1. FIG.

  The light emitting unit 20 includes a power source 21 and a light emitter 22. The configuration of the power source 21 is the same as that of the marking tool 1 described above. The light emitter 22 is formed in a spherical shape, and is provided in the space 11 a of the body portion 11. The light emitter 22 is connected to the power source 21 via the cord 24, and power is supplied therefrom.

  The light emitter 22 has a translucent spherical shell and a light source accommodated therein. The size of the spherical shell is appropriately determined so that the light emitter 22 has the same specific gravity as the marking liquid 40. Thereby, the light emitter 22 floats in the marking liquid 40 in the container body 10, and emits light from the marking liquid 40 into the container body 10. Can be phosphorescent.

  As described above, the marking liquid 40 is put into the hard container body 10 made of stainless steel, for example, and sprayed by aerosol spray. However, you may design the container main body 10 and the injection part arbitrarily. For example, you may use the pump type spray which sprays the marking liquid 40 by the pressure difference of the container main body 10 and a nozzle part by a user holding a trigger and operating a pump. Moreover, what the thin tube penetrated to the flexible container main body 10 like the washing bottle used for a science experiment can also be used. In this case, without using the propellant 41, it is possible to simply put the marking liquid into the container body 10 and push the container body (increase the internal pressure) to eject the marking liquid 40 from the tube.

  Note that the phosphorescent substance reacts with the translucent liquid, particularly water, in the marking liquid 40 to reduce the phosphorescence and luminescence. Therefore, it is preferable to perform water resistance processing by coating the powder of the phosphorescent substance with a translucent material such as glass or resin.

  When processing is performed to provide water resistance for a long period (for example, 3 months), the particle size of the phosphorescent substance powder increases. If this makes it difficult to use an aerosol spray, a pump spray or cleaning bottle can be used.

  In addition, it may be possible to cope with a large particle size by widening the jet of the marking liquid 40 by the nozzle unit 30 (increasing the diameter of the jet port). While fine marking such as writing letters becomes difficult, it is sometimes useful because it is sprayed over a wide range in a short time. You may make it a wide angle regardless of water-resistant processing.

  In this embodiment, a container that separates and stores the marking liquid and the luminous substance is used. The other points are the same as in the first embodiment, and the same or corresponding parts as in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

  In FIG. 4, the internal structure of the marking tool 3 which concerns on a present Example is shown. In addition, while attaching | subjecting the same code | symbol about the part which is the same as or corresponding to the above-mentioned marking tool 1, the detailed description is abbreviate | omitted.

The container body 10 is formed using a metal such as steel, for example, and includes the body 11, the bottom 12, the head 13, and the separating means 14. In the marking tool 3 according to this modification, the liquid 42 does not need to have translucency because the powder 43 of the phosphorescent material is separated from the liquid 42 and stored and stored as described later. A liquid such as water colored in an arbitrary color may be used. Here, as an example, it is assumed that the above-described translucent liquid is colored. Thereby, after marking by injecting the marking liquid 40, the mark can be visually recognized even in a bright environment.

The trunk portion 11 is located at the center of the container body 10. Barrel 11, a cylindrical shape having a bottom surface 14a having a plurality of holes 14a ₀ is formed, and a stepped portion 11b is formed at the lower end of the side surface.

Parts that are the same as or correspond to those of the marking tool 3 described above are given the same reference numerals, and detailed descriptions thereof are omitted. The marking tool 4 is different from the above-described marking tool 3 in the configuration of the separating means.

  The container body 10 is a container that separates and stores the phosphorescent substance powder 43 and the liquid 42 constituting the marking liquid 40. The container body 10 is formed to include the body 11, the bottom 12, the head 13, and the separation means 15 using a metal such as steel. In the marking tool 4 according to this modification, a liquid such as water colored in an arbitrary color is used as the liquid 42 as in the case of the marking tool 3 described above.

The trunk portion 11 is located at the center of the container body 10. The trunk portion 11 has a cylindrical shape having a bottom surface 15a that forms a separation membrane, and a step portion 11b is formed at the lower end of the side surface.
