[Modes for carrying out the invention]

[0009] In the protective device according to the first embodiment of the present invention, light-emitting body storage bags are attached to both sides of the back portion, and a strip-shaped light-emitting body, which is made up of multiple connected light sources, is placed inside the light-emitting body storage bags so that the strip-shaped light-emitting body can move inside the light-emitting body storage bags. According to this embodiment, the strip-shaped light-emitting elements are positioned on both sides of the back, preventing damage to the strip-shaped light-emitting elements from obstacles during work and ensuring visibility due to less contamination from dust and other particles. Furthermore, according to this embodiment, the strip-shaped light-emitting elements are placed inside the light-emitting element storage bag, allowing them to move within the bag without affecting the wearer's bending movements, and preventing any load from being placed on the strip-shaped light-emitting elements by the wearer's bending movements.

[0010] A second embodiment of the present invention is a protective device according to the first embodiment, wherein a cord for a strip-shaped light-emitting element extends from the lower end of the light-emitting element storage bag, and the longitudinal length of the light-emitting element storage bag is made longer than the longitudinal length of the strip-shaped light-emitting element, thereby allowing the strip-shaped light-emitting element to move in the longitudinal direction of the light-emitting element storage bag. According to this embodiment, the strip-shaped light-emitting element can also move in the longitudinal direction of the light-emitting element storage bag, and furthermore, it does not affect the wearer's movements such as bending over, nor does the wearer's movements such as bending over put any load on the strip-shaped light-emitting element.

[0011] A third embodiment of the present invention is a protective device according to the first embodiment, wherein the light-emitting element storage bag is made of mesh material. According to this embodiment, by forming the light-emitting body storage bag from a mesh material, it can be made highly flexible and its visibility can be enhanced by the light scattering effect. [Examples]

[0012] The following describes a protective device according to one embodiment of the present invention. Figure 1 is a photograph of the protective gear according to this embodiment taken from the rear at an angle to the wearer, Figure 2 is a photograph of the protective gear taken from the rear to the wearer, Figure 3 is a photograph of the protective gear taken from the front to the wearer, Figure 4 is a photograph of the protective gear taken from the side to the wearer, Figure 5 is a photograph showing the main part of the protective gear, Figure 6 is a photograph from the rear showing the protective gear in use in darkness, and Figure 7 is a photograph from the rear showing the protective gear in use in darkness.

[0013] The protective gear according to this embodiment comprises a back portion 11 that protects the wearer's back, a pair of shoulder portions 12 that are continuous with the upper part of the back portion 11 and protect the wearer's shoulders, a collar portion 13 that is continuous with the upper part of the back portion 11 and protects the back of the wearer's neck, a pair of front portions 14 that are continuous with the pair of shoulder portions 12 and hang down toward the wearer's chest, a shoulder belt 15 that connects each of the front portions 14 to the back portion 11, a chest belt 16 that connects the pair of front portions 14, and a waist belt 17 that connects both sides of the lower part of the back portion 11. The back portion 11, shoulder portion 12, and collar portion 13 are equipped with multiple rod-shaped cushioning materials 18 running horizontally.

[0014] The back portion 11, shoulder portion 12, and collar portion 13 each have a two-layer structure, and the rod-shaped cushioning material 18 is placed between the two layers. The space between adjacent rod-shaped cushioning materials 18 is recessed, and by arranging multiple rod-shaped cushioning materials 18 in the horizontal direction, it can form a curved shape that conforms to the wearer's body and can change shape to follow the wearer's movements, such as bending over. The length of the rod-shaped cushioning material 18 in the longitudinal direction is shorter than the lateral width of the back portion 11, the lateral width of the shoulder portion 12, or the lateral width of the collar portion 13. For example, an inclined surface is formed between an end of the rod-shaped cushioning material 18 and a side end of the back portion 11.

[0015] In the present embodiment, a reflective material 19 is provided on the back portion 11 at a convex portion formed by the rod-shaped cushioning material 18. Luminous body storage bags 21 are attached to both sides of the back portion 11. It is preferable that the belt-shaped luminous body 22 extends not only to the back portion 11 together with the luminous body storage bag 21 but also to a part of the shoulder portion 12. However, as shown in Fig. 3, it is preferable that the luminous body storage bag 21 or the belt-shaped luminous body 22 does not extend to a position invisible from the front surface, that is, a position beyond the top of the shoulder portion 12. That is, by extending the belt-shaped luminous body 22 to a part of the shoulder portion 12, light can be emitted in a wide range to improve visibility, and it is preferable that the belt-shaped luminous body 22 does not enter the wearer's field of view.

[0016] Fig. 5(a) is part A shown in Fig. 4, and Fig. 5(b) is part B shown in Fig. 4. As shown in Fig. 5, the belt-shaped luminous body 22 is disposed inside the luminous body storage bag 21. The luminous body storage bag 21 is formed of a mesh material. The belt-shaped luminous body 22 is formed by connecting a plurality of light-emitting sources 22a and covering the light-emitting sources 22a with a flexible material. Here, as the flexible material, for example, silicon or polyester can be used. By using silicon or polyester, sufficient durability is provided even in an alkaline environment, for example, in tunnel construction. As shown in Fig. 5(a), the belt-shaped luminous body 22 is disposed inside the luminous body storage bag 21, and the longitudinal length of the luminous body storage bag 21 is made longer than the longitudinal length of the belt-shaped luminous body 22, whereby the belt-shaped luminous body 22 can move inside the luminous body storage bag 21. As shown in Fig. 5(b), a cord 22b of the belt-shaped luminous body 22 extends from the lower end of the luminous body storage bag 21. A storage pocket is provided at a lower portion of a wearer-side surface of the back portion 11, and a battery is stored in the storage pocket. The cord 22b is connected to the battery. Furthermore, the lower end of the light-emitting body storage bag 21 is narrowed to prevent the strip-shaped light-emitting body 22 from coming out of the lower end of the light-emitting body storage bag 21. The strip-shaped light-emitting body 22 may be partially fixed to the light-emitting body storage bag 21, and it is preferable that this partially fixed portion has a material or structure that allows the strip-shaped light-emitting body 22 to be displaced relative to the light-emitting body storage bag 21. With such a fixed portion, the light-emitting body storage bag 21 can support the strip-shaped light-emitting body 22, and the strip-shaped light-emitting body 22 can be supported in an appropriate position relative to the light-emitting body storage bag 21.

[0017] As shown in Figures 6 and 7, the strip-shaped light-emitting element 22 is illuminated or flashes in the dark. Because the light-emitting element storage bag 21 is made of mesh material, there is a scattering effect, and further reflection from the inclined surface formed from the end of the rod-shaped cushioning material 18 to the side end of the back portion 11 provides high visibility.

[0018] As described above, according to this embodiment, since the strip-shaped light-emitting elements 22 are located on both sides of the back portion 11, damage to the strip-shaped light-emitting elements 22 by obstacles during work can be prevented, and visibility can be ensured because there is less dirt from dust and other particles. Furthermore, according to this embodiment, by arranging the strip-shaped light-emitting element 22 inside the light-emitting element storage bag 21 and allowing the strip-shaped light-emitting element 22 to move inside the light-emitting element storage bag 21, it does not affect the wearer's movements such as bending over, and no load is placed on the strip-shaped light-emitting element 22 by the wearer's movements such as bending over. Furthermore, according to this embodiment, since the strip-shaped light-emitting element 22 can also move in the longitudinal direction of the light-emitting element storage bag 21, it does not affect the wearer's bending movements, nor does the bending movements of the wearer put any load on the strip-shaped light-emitting element 22. Furthermore, according to this embodiment, since the strip-shaped light-emitting body 22 is formed by covering the light source 22a with a flexible material, it does not affect the wearer's bending movements, and no load is placed on the strip-shaped light-emitting body 22 by the wearer's bending movements. Furthermore, according to this embodiment, by forming the light-emitting body storage bag 21 from a mesh material, it can be made highly flexible and its visibility can be enhanced by the light scattering effect.
