Description

[Technical field]

[0001] The present invention relates to a storage bag for storing items, and more particularly to a storage bag that makes it easy to find the owner who is carrying it from a distance at night or in bad weather. [Background technology]

[0002] Emergency evacuation bags are now widely used to carry emergency supplies and valuables quickly when evacuating in the event of an emergency such as an earthquake or flood. Most emergency evacuation bags are backpack-style so that people can use both hands to respond to an emergency, and some existing products use eye-catching colors such as red and yellow. However, even if the bag is colored in an eye-catching color, it is difficult to find evacuees who are far away at night or in bad weather.

[0003] On the other hand, as a technique for providing a light source in a storage bag, the techniques described in Patent Documents 1 and 2, for example, are known.

[0004] The technology described in Patent Document 1 is a bag equipped with an internal light source for night lighting. The technology described in Patent Document 2 comprises a storage section for storing items, a pair of shoulder belts for being worn over both shoulders of the user and provided on the second side of the storage section formed to abut against the user's back, an emergency bag side interface formed on the bottom of the storage section and coupled to an interface on the docking station side, a power line connected to the emergency bag side interface and supplying power from the docking station, a socket provided on the first side of the storage section and having a first power terminal connected to the power line, and a flashlight having a first storage battery that is detachably attached to the socket and charged by power supplied from the power line while attached to the socket.

[0006] However, in the technology described in Patent Document 1, a light source illuminates the inside of the bag to search for items inside the bag at night, making it difficult to find evacuees who are far away at night or in bad weather.

[0007] In addition, in the technology described in Patent Document 2, the flashlight is removed from the storage section during evacuation and used as a handheld flashlight, making it difficult to find evacuees who are far away at night or in bad weather.

[0008] Therefore, the present invention has been made with a focus on the unresolved problems of such conventional technology, and aims to provide a storage bag that makes it easy to find the owner who is carrying it from a distance, such as at night or in bad weather. [Means for solving the problem]

[0009] [Invention 1] In order to achieve the above-mentioned objective, the storage bag of invention 1 comprises a storage section made of a material having light-transmitting and light-diffusing properties for storing items, and an illuminant provided inside the storage section so as to radiate light outward from the storage section.

[0010] With this configuration, when the light emitter emits light, the light is radiated outward from the storage section. Since the material of the storage section has light transmissive and light diffusive properties, the storage section emits light by diffusing the light.

[0011] [Invention 2] Furthermore, the storage bag of invention 2 is the storage bag of invention 1, wherein the material has a light transmittance of 30% or more and a light diffusion rate of 40% or more.

[0012] [Invention 3] Furthermore, the storage bag of invention 3 is the storage bag of invention 1, further comprising a switch for switching the light-emitting body between emitting and not emitting light, the switch being provided on the outside of the storage section.

[0013] With this configuration, the light emitter can be switched between emitting and not emitting light by operating the switch provided on the outside of the storage section.

[0014] Here, the switch includes, for example, a one-way switch that switches the light-emitting body only from non-emitting to emitting, a one-way switch that switches the light-emitting body only from emitting to non-emitting, or a two-way switch that switches the light-emitting body from either emitting or non-emitting to the other.

[0015] [Invention 4] Furthermore, the storage bag of invention 4 is equipped with a control means for controlling the emission and non-emission of the light-emitting element so as to produce an emission pattern that indicates specified information, in the storage bag of invention 1.

[0016] With this configuration, the control means controls the light emission and non-emission of the light emitters to produce a light emission pattern that indicates predetermined information.

[0017] Here, the predetermined light emission pattern includes, for example, a light emission pattern showing a Morse code, or a light emission pattern in which a plurality of storage bags are arranged in a predetermined arrangement (for example, in the shape of the letters SOS) and the storage bags flash in synchronization with each other. In the latter case, a synchronization means for synchronizing the light emission and non-emission of the light emitters of the other storage bags may be provided.

[0018] [Invention 5] Furthermore, the storage bag of invention 5 is a storage bag of any one of inventions 1 to 4, which is equipped with a float mechanism for floating on water.

[0019] With this configuration, even if the user is in a drowning situation, the storage bag will float on the water and emit light by diffusing it. Effect of the Invention

[0020] As explained above, the storage bag of Invention 1 makes it easier to find the carrier from a distance, at night or in bad weather, compared to conventional methods.

[0021] Furthermore, the storage bag of Invention 2 makes it easier to find the carrier from a distance, such as at night or in bad weather.

[0022] Furthermore, the storage bag of Invention 3 makes it easy to switch the light-emitting element between emitting and not emitting light. Furthermore, the storage bag of invention 4 makes it possible to transmit specified information.

[0023] Furthermore, the storage bag of Device 5 makes it easier to find the owner in case of drowning. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] First Embodiment A first embodiment of the present invention will be described below. Figures 1 to 3 are diagrams showing the present embodiment.

[0026] First, the configuration of this embodiment will be described. FIG. 1 is a perspective view of an emergency bag 100 as seen from the rear.

[0027] FIG. 2 is a cross-sectional view of the emergency bag 100 as viewed from the left side. 1, the emergency evacuation bag 100 is a backpack-type bag worn on the back, and is configured with a storage section 10 for storing items, a pair of shoulder belts 12 that are hung from the shoulders of a user, and a waist belt 14 that is worn around the user's waist. The user can wear the emergency evacuation bag 100 on the back by passing both shoulders through the shoulder belts 12 and fastening the waist belt 14.

[0028] The shoulder belt 12 is provided with an adjuster 12a for adjusting the length of the shoulder belt 12. The user can adjust the length of the shoulder belt 12 with the adjuster 12a so that it fits both shoulders.

[0029] A buckle 14a for fastening the waist belt 14 is provided at the tip of the waist belt 14. The user can wear the waist belt 14 around his / her waist by wrapping the waist belt 14 around his / her waist and fastening the waist belt 14 with the buckle 14a.

[0030] The storage section 10 is made of a fabric made of a material having light transmission and light diffusion properties. Examples of the fabric material that can be used include synthetic fibers such as nylon, polyester, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and acrylic that have light transmission properties, natural fibers such as cotton and hemp, and light-transmitting inorganic fibers such as glass fibers. Woven or nonwoven fabrics made of these fibers can be further coated with urethane resin, PVC, silicone resin, fluororesin, or the like to make them waterproof.

[0031] Even if fibers are not used, resin in the form of a flexible continuous sheet or film can be used as the fabric material.

[0032] Particularly preferred fabrics include oxford-woven nylon fibers, polyester fibers, etc., which have been treated with waterproof resin, tarpaulins, PVC sheets, etc.

[0033] These materials preferably contain dyes or pigments to give them colors that stand out from a distance, such as yellow, orange, or red.

[0034] The range of light transmittance as an index of light transmittance is preferably 30% or more in the visible light region, more preferably 50% or more. If it is less than 30%, the light's reach becomes short, making it difficult to see from a distance at night, which is not preferable.

[0035] The range of light diffusion rate as an index of light diffusion is 40% or more when measured by the diffuse reflected light intensity described later. If it is less than 30%, it is not preferable because visibility during the day decreases.

[0036] The waterproofness of the storage section 10 is preferably such that it has a high water pressure resistance, and more preferably a water pressure resistance of 2000 mm or more, so that the emergency bag 100 will not be submerged in the event of a flood.

[0037] Next, an embodiment of the material of the storage section 10 will be described. [First embodiment] In the first example, a PVC waterproof nylon cloth (orange color) was used as the material of the storage section 10, and the light transmittance and light diffusion rate of the material were measured by the following method.

[0038] The light transmittance is measured by placing a surface-emitting white LED behind the fabric and measuring the intensity of the light transmitted through the fabric with a visible light sensor. The transmitted light intensity without the fabric is set to 100, and the ratio of the transmitted light intensity through the fabric is calculated as a percentage.

[0039] The light diffusion rate is measured by placing a black cloth in front of the visible light sensor, placing a fabric between the black cloth and the light sensor, irradiating the fabric with white LED light from a diagonal angle from the front at a specified angle of incidence (e.g. 45°), and measuring the diffuse reflected light intensity with the visible light sensor.Then, the diffuse reflected light intensity when a white board is placed instead of the fabric is set to 100, and the ratio of the diffuse reflected light intensity of the fabric to this is calculated in %.

[0040] As a result, the light transmittance of the fabric was 50% and the light diffusion rate was 55%. [Second embodiment] In the second example, a polyester fabric (yellow) that was polyurethane waterproofed was used as the fabric of the storage section 10, and the light transmittance and light diffusion rate of the fabric were measured by the above-mentioned method.

[0041] As a result, the light transmittance of the fabric was 60% and the light diffusion rate was 65%. An illuminant 16 is provided on the inner bottom of the storage section 10. A switch 18 for switching the illuminant 16 between emitting and not emitting light is provided below the illuminant 16. A user can switch the illuminant 16 between emitting and not emitting light by operating the switch 18.

[0042] The type of light emitter 16 is not particularly limited, but a low-power LED that can be powered by a dry cell is preferable, and the color of the light emitter 16 is preferably white to yellow or red, which is less likely to be scattered or absorbed by the atmosphere or dust.

[0043] The light emitter 16 is preferably an LED with low directivity, and also preferably has light diffusing properties and low directivity due to a diffusion plate, optical waveguide, optical fiber, or the like.

[0044] The switch 18 is provided with a control unit (not shown) that controls whether the light emitter 16 emits light or not.

[0045] The control unit is made up of an MPU (Micro-Processing Unit) or the like, and controls the light emitter 16 so that the light emitter 16 emits light continuously in response to the operation of the switch 18 .

[0046] The control unit controls the light emitter 16 so that the light emitter 16 blinks in response to the operation of the switch 18. In a first operation mode, the user can manually blink the light emitter 16 by operating the switch 18. In a second operation mode, the blinking of the light emitter 16 is controlled to be a pre-programmed light emission pattern. As the light emission pattern, for example, Morse code or any digital signal information can be transmitted by visible light communication. By providing such a function, it can be used as a means for transmitting more information in an emergency. The type of information that can be transmitted is not particularly limited, but examples include the presence or absence of injuries, the number of people seeking rescue, their ages, and genders, and it is also possible to pre-register personal information such as a My Number that can identify an individual in the control unit as a light emission pattern. In a third operation mode, the control unit is connected to the control unit of another emergency evacuation bag 100 by wireless communication or the like, and the light emitters 16 of those emergency evacuation bags 100 are controlled to blink in synchronization with each other.

[0047] A float 20 is provided inside the storage section 10. The float 20 is provided with an air valve 22 for introducing air into the float 20. The air valve 22 is provided so as to penetrate the storage section 10 and protrude to the outside from the front of the storage section 10. As the float 20, it is more preferable to adopt a float that provides buoyancy such that the emergency evacuation bag 100 remains above the water surface even if an evacuee is swept away during a flood, so that rescuers do not lose track of the bag's location, and so that the emergency evacuation bag 100 continues to emit light even at night.

[0048] The float 20 preferably has a hollow structure that can be filled with foam or air, and the type of resin is not particularly limited, but relatively soft materials such as urethane, polyvinyl chloride, polyethylene, ethylene-vinyl acetate copolymer (EVA), and polyethylene are preferred.

[0049] In this embodiment, for example, a white LED can be used as the light emitter 16, a push button switch can be used as the switch 18, and a hollow polyethylene float can be used as the float 20.

[0050] Next, the operation of this embodiment will be described. FIG. 3 is a diagram for explaining how to use the emergency bag 100. As shown in FIG.

[0051] As for the method of using the emergency evacuation bag 100, as shown in FIG. 3(a), when evacuating to a shelter, the bag can use light to indicate the urgency of the evacuation and the direction in which the evacuees should head to other evacuees and to those who have not yet evacuated but are about to head to the shelter, thereby encouraging a quick and efficient evacuation and also allowing evacuation guides to easily find and direct evacuees even in the darkness of night.

[0052] In addition, as shown in Figure 3(b), rescuers and searchers can easily find evacuees and victims who are left behind on roofs or in isolated places during a flood, even when searching in bad weather or at night.

[0053] Furthermore, as shown in FIG. 3(c), by arranging multiple emergency evacuation bags 100 in a predetermined arrangement (for example, in the shape of the letters SOS), the emergency evacuation bags 100 can be made to flash in sync, making it easier for rescuers or searchers to find evacuees or victims even when searching in bad weather or at night.

[0054] Next, the effects of this embodiment will be described. In this embodiment, the emergency evacuation bag 100 comprises a storage section 10 made of a material having optical transparency and optical diffusion properties for storing items, and an illuminant 16 provided inside the storage section 10 so as to radiate light toward the outside of the storage section 10.

[0055] This makes it easier to find evacuees far away at night or in bad weather, compared to the past. In addition, the emergency evacuation bag 100 can be worn by a shoulder strap or the like during emergency evacuation in the event of a disaster, making the location of the evacuees easily visible from the surroundings, facilitating group evacuation and guidance by guides, and also making the location of the evacuees known regardless of day or night while waiting for rescue at the evacuation destination, which can lead to early rescue.

[0056] Furthermore, in this embodiment, the material of the storage section 10 has a light transmittance of 30% or more and a light diffusion rate of 40% or more. This will make it easier to find evacuees who are far away, such as at night or in bad weather.

[0057] Furthermore, in this embodiment, the emergency bag 100 includes a control unit that controls the light emitters 16 to emit light or not to emit light so as to produce a light emission pattern that indicates predetermined information. This makes it possible to transmit predetermined information.

[0058] Furthermore, in this embodiment, the emergency bag 100 includes a float 20 for making it float on water. This makes it easier to find evacuees who are in water danger.

[0059] Second Embodiment Next, a second embodiment of the present invention will be described. Fig. 4 is a diagram showing this embodiment. Below, only the parts that are different from the first embodiment will be described, and the explanation of the overlapping parts will be omitted.

[0060] First, the configuration of this embodiment will be described. FIG. 4 is a cross-sectional view of the emergency bag 100 as viewed from the left side.

[0061] 4, the emergency bag 100 is configured to have a storage section 10, a shoulder belt 12, a waist belt 14, a light emitter 16, a switch 18, and a float 20. For example, a white LED can be used as the light emitter 16, a slide switch can be used as the switch 18, and a float made of foamed EVA resin can be used as the float 20.

[0062] A hollow donut-shaped float 20 is provided vertically on the rear side inside the storage section 10. The hollow portion of the float 20 opens toward the front side of the storage section 10, and a light emitter 16 is provided in the hollow portion.

[0063] The switch 18 is provided so as to penetrate the storage section 10 and extend to the outside from the rear surface of the storage section 10. The switch 18 is attached to the shoulder belt 12.

[0064] Next, the effects of this embodiment will be described. In this embodiment, the switch 18 is provided on the outside of the storage section 10 .

[0065] This makes it easy to switch the light emitter 16 between emitting and not emitting light. [Modifications] In the first and second embodiments, the storage section 10 may have a multi-layer structure. For example, the storage section 10 may be composed of an inner bag and an outer bag. This allows the storage section 10 to have light transmittance, light diffusion, waterproofness, and visibility due to a conspicuous color. In this case, for example, a colored material having light transmittance and light scattering properties may be used for the inner bag, and a colorless transparent waterproof film having light transmittance but no light scattering properties may be used for the outer bag. Also, for example, a white material having light transmittance and light scattering properties may be used for the inner bag, and a colored waterproof transparent sheet may be used for the outer bag.

[0066] Preferred materials for the inner bag include woven fiber fabrics such as polyester, polypropylene, and cotton, nonwoven fabric, and Japanese paper, while preferred materials for the outer bag include PVC sheet, film, nylon and polyester waterproofed with polyurethane, PVC, silicone resin, etc.

[0067] Furthermore, when the storage section 10 has a multi-layer structure, it can be used by simply stacking the pieces, or by integrating them together by lamination or the like.

[0068] In the first and second embodiments and their modifications, a light reflector (for example, retroreflective tape) may be provided on a portion of the surface of the storage section 10.

[0069] Moreover, the above-mentioned first and second embodiments and the modifications thereof can be applied to each other.

[0070] In the above first and second embodiments and their modifications, the present invention is applied to an emergency bag, but it is not limited to this and can be applied to other cases without departing from the spirit of the present invention. For example, it can be applied to a backpack, a bag, a suitcase, or other storage bags, or storage bags for purposes other than emergencies. [Explanation of symbols]
