Abstract
Description
Technical Field
[0001] The present invention relates to an interior material and a folding hood used for a head protector such as a disaster prevention hood, which is configured to be in a deployed state that can be worn on the human head during use and in a folded state that is folded when not in use.
Background Art
[0002] Conventionally, when a disaster victim such as in an earthquake or a fire takes shelter, a head protector such as a disaster prevention hood is known to cover the head and protect the head of the wearer (hereinafter referred to as the "wearer". The same applies in this specification) from falling objects, flying objects, etc.
[0003] As such a head protector, for example, the disaster prevention headscarf described in Patent Document 1 can be considered. This disaster prevention headscarf 1 is formed of a long fibrous body having a bent portion 2a that is folded in half at the central portion. With such a configuration, it can be stored in a flat and non-bulky shape by folding it during normal times, and during a disaster, it can be deployed and worn by the wearer on the head for protecting the head. The disaster prevention headscarf 1 has a head protection portion 2e that includes the bent portion 2a and at least protects the head.
[0004] This disaster prevention headscarf described in Patent Document 1, due to its simple configuration, is used not only by adults but also by many infants and children, and is widely used in nurseries, kindergartens, elementary schools, etc.

Summary of the Invention
Problems to be Solved by the Invention
[0006] Here, the disaster prevention hood described in Patent Document 1 has a head protection portion made of soft fibers. Therefore, this disaster prevention hood can protect the wearer's head from relatively small or soft flying objects. However, the disaster prevention hood described in Patent Document 1 has the problem that it is difficult to protect the wearer's head, especially the top of the head, from the impact of collisions with large or hard flying objects, or from being impaled by falling protrusions. Even if a hard protective member were attached to the top of the head of the disaster prevention hood described in Patent Document 1, if a large or heavy flying object or protrusion collides with the protective member, the protective member will hit the head, causing impact or injury to the head.
[0007] This invention has been made in view of the above problems, and aims to provide an interior material for a head protection device and a foldable hood that can mitigate the impact to the head caused by flying objects, falling objects, or collisions with protruding objects. [Means for solving the problem]
[0008] To achieve the above objective, the invention described in claim 1 is an interior material for a head protector that can change shape between an unfolded state in which a covering portion that covers at least the head of the wearer forms a three-dimensional shape and a folded state in which the covering portion becomes flat, wherein the covering portion is attached to the wearer's head in the unfolded state, and is characterized by comprising: a crown protection portion made of a rigid material and located at least on the top of the wearer's head and provided on the upper side of the head; a peripheral protection portion made of a rigid material and pivotably supported by a shaft portion relative to the crown protection portion, and changing its position relative to the crown protection portion by the rotation of the shaft portion in the unfolded state and the folded state; and an upper protection portion provided so as to cover at least a part of the upper side of the crown protection portion, and formed in a three-dimensional shape from a softer material than the crown protection portion to mitigate external impacts applied to the top of the wearer's head.
[0009] The invention described in claim 2 is characterized in that, in addition to the configuration described in claim 1, the upper protective portion is formed to cover the upper part of at least a portion of the shaft portion that pivotally supports the peripheral protective portion relative to the crown protective portion.
[0010] The invention described in claim 3 is characterized in that, in addition to the configuration described in claim 1, the upper protective portion is formed to be thicker than the crown protective portion.
[0011] The invention described in claim 4 is characterized in that, in addition to the configuration described in claim 1, the upper protective portion is integrally formed from foamed resin.
[0012] The invention described in claim 5 is characterized in that, in addition to the configuration described in claim 1, a fitting portion is provided on the upper surface of the crown protection portion, while a fitting portion that fits into the fitting portion is provided on the lower surface of the upper protection portion.
[0013] The invention described in claim 6 is characterized in that, in addition to the configuration described in claim 1, a lower protective portion is provided below the crown protective portion.
[0014] The invention described in claim 7 is a foldable hood characterized by being provided with the interior material for a head protector described in any one of claims 1 to 6. [Effects of the Invention]
[0015] According to the invention described in claim 1, by providing a hard crown protection portion located at least on the top of the wearer's head and provided on the upper side of the head, it is possible to prevent the wearer's head from being struck by falling objects or being impaled by protrusions. Furthermore, by providing a hard peripheral protection portion, it is possible to prevent the wearer's head from being struck by falling objects or being impaled by protrusions around the top of the wearer's head. In addition, by changing the position of the peripheral protection portion relative to the crown protection portion by rotating the shaft portion, the shape of the interior material for the head protection portion can be freely changed between an unfolded state and a folded state. Furthermore, an upper protection portion, which is provided so as to cover at least a part of the upper side of the crown protection portion and is formed in a three-dimensional shape from a softer material than the crown protection portion, can mitigate the impact on the wearer's head even if a large flying object or heavy falling object collides with the wearer's head or a protrusion falls. This makes it possible to provide a disaster prevention hood that can mitigate the impact on the head caused by flying objects, falling objects, or impacts from protrusions.
[0016] According to the invention described in claim 2, the upper protective portion is formed to cover the upper part of at least a portion of the shaft portion that pivotally supports the peripheral protective portion relative to the crown protective portion, thereby preventing flying objects, falling objects, or protrusions from colliding with the shaft portion and enhancing safety.
[0017] According to the invention described in claim 3, the upper protective portion is formed to be thicker than the top protective portion, thereby reliably mitigating the impact on the head caused by flying objects, falling objects, or protrusions.
[0018] According to the invention described in claim 4, the upper protective portion is integrally formed from foamed resin, thereby reliably mitigating the impact on the head caused by flying objects, falling objects, or protrusions.
[0019] According to the invention described in claim 5, a fitting portion is provided on the upper surface of the top protection portion, while a fitting portion that fits into the fitting portion is provided on the lower surface of the upper protection portion. By fitting the fitting portion of the upper protection portion into the fitting portion of the top protection portion, it is possible to prevent the upper protection portion from shifting or coming off relative to the top protection portion. As a result, impacts on the head caused by collisions with flying objects, falling objects, or protruding objects can always be reliably alleviated, and reliability is improved.
[0020] According to the invention described in claim 6, since a lower protection portion is provided below the top protection portion, impacts on the head caused by collisions with flying objects, falling objects, or protruding objects can be more reliably alleviated.
[0021] According to the invention described in claim 7, the foldable apron provided with the interior material for a head protector according to any one of claims 1 to 6 can prevent the wearer's head from being impacted by falling objects or penetrated by protruding objects in the deployed state, and the covering portion can protect the entire head of the wearer from flying objects and heat. Also, in the folded state, the covering portion can be used as a cushioned mat. And at the evacuation site during a disaster or the like, by folding the head protector and using it as a mat, the wearer can continue to sit comfortably regardless of the hardness or unevenness of the floor surface. As a result, it is possible to alleviate impacts on the head caused by collisions with flying objects, falling objects, or protruding objects, and a disaster prevention apron that can make the sitting posture of the wearer after evacuation comfortable can be realized.

[Embodiments for Carrying Out the Invention]
[0023] Hereinafter, embodiments of this invention will be described with reference to the drawings.
[0024] [Embodiments of the Invention] FIGS. 1 to 13 show embodiments of this invention.
[0025] [Overall Configuration] First, briefly explaining the configuration, the disaster prevention bandana 10A as the "head protector" of this embodiment shown in FIGS. 1 and 2 is a disaster prevention bandana for children and is formed in a size suitable for children such as kindergarten children and schoolchildren to wear on their heads. However, the disaster prevention bandana 10A may be formed in a size suitable for an average adult to wear on their head.
[0026] [Unfolded state and folded state] As shown in Figures 1 and 2, the disaster prevention hood 10A of this embodiment can be formed into an unfolded state (hereinafter simply referred to as "unfolded state") that covers at least the head 101 of the wearer 100, as schematically shown in Figure 10. On the other hand, the disaster prevention hood 10A can change shape to a folded state (hereinafter simply referred to as "folded state," not shown) that is smaller than the unfolded state. In the folded state, the disaster prevention hood 10A can take the shape of a flat, roughly rectangular plate in plan view, for example. As will be described later, the disaster prevention hood 10A in the folded state can be used as a cushion for the wearer 100 to place on the floor or chair to sit on.
[0027] The disaster prevention hood 10A of this embodiment, as shown in Figures 1 and 2, includes an interior material 11 and a covering part 12, which are "interior materials for head protection equipment".
[0028] [Interior materials] Figures 1 and 2 show the interior material of this embodiment. The interior material 11 of this embodiment comprises an interior material main body 1, a head circumference fastening part 2, and a chin strap 3.
[0029] [Interior material main body] The main body 1 of the interior material in this embodiment includes the helmet shell 4 shown in Figure 2, and further includes impact mitigation parts 15, 16, an upper protective part 7, a lower protective part 8, and a crown contact part 9 shown in Figure 2.
[0030] [helmet shell] The helmet body 4 in this embodiment protects the top of the head and the surrounding area of the wearer 100 of the disaster prevention hood 10A, and is formed in a roughly plate-like shape from a rigid material. As shown in Figure 3, the helmet body 4 comprises a helmet body portion 5 and protectors 6, 6.
[0031] The helmet body 5 is formed from a highly rigid material, such as a resin like polypropylene, into a roughly rectangular, plate-like shape when viewed from above.
[0032] The helmet body 5 comprises a crown protection body 18 located approximately in the center in the width direction, and a pair of peripheral protection body 19, 19 located symmetrically on either side of the crown protection body 18. Thin-walled hinges 17, 17, acting as "shafts," are provided between the crown protection body 18 and the peripheral protection body 19, 19.
[0033] The crown protection main body 18, the thin-walled hinges 17,17, and the peripheral protection main body 19,19 are integrally molded into a roughly rectangular, plate-like shape in plan view. The bottom view side of the crown protection main body 18 and the peripheral protection main body 19,19 of the helmet body 5 is formed with a large thickness and high rigidity, while the thin-walled hinge 17 is formed with a small thickness and easily bendable.
[0034] The crown protection body 18 of the helmet body 5, together with the upper protection body 7 and the lower protection body 8, constitutes the crown protection body 13, which will be described later.
[0035] The peripheral protective body parts 19, 19 of the helmet body 5, together with the protectors 6, 6, constitute the peripheral protective body parts 14, 14 described later. The peripheral protective body parts 19, 19 are provided with numerous convex reinforcing parts (not shown) in the vertical and horizontal directions. These reinforcing parts increase the rigidity of the helmet body 5. Furthermore, by forming the above reinforcing parts only on a part of the helmet body 5, the weight of the helmet body 5 can be reduced.
[0036] The protector 6 is formed in a roughly rectangular shape in plan view from a highly rigid material, such as a highly rigid resin like polycarbonate. The protector 6 is attached to the main body 5 of the helmet shell 4 on the plan view side.
[0037] As shown in Figures 4 and 5, the protector 6 is provided with numerous reinforcing parts (not shown) that are raised in a convex shape, running vertically and horizontally. Similar to the reinforcing parts on the helmet body 5, the provision of reinforcing parts on a part of the protector 6 increases the rigidity of the protector 6 and also reduces the weight of the protector 6.
[0038] [Parietal protection part] As shown in Figures 4 and 5, the helmet shell 4 is equipped with a crown protection section 13. The crown protection section 13 comprises a roughly band-shaped crown protection main body 18 formed by the approximate center of the helmet shell main body 5, an upper protection section 7, and a lower protection section 8.
[0039] The crown protection body portion 18 is made up of a part of the helmet body portion 5. The crown protection body portion 18 has multiple protrusions 18a and multiple recesses 18b that serve as "fitting portions" formed along its longitudinal direction, providing both high rigidity and lightweight design.
[0040] The crown protection body 18 is formed in a roughly plate-like shape with a length approximately equal to the diameter of the wearer's head 101. However, the length of the crown protection body 18 may be longer or shorter than the diameter of the wearer's head 101, as long as it can protect the area near the crown of the wearer's head. Furthermore, the width and thickness of the crown protection body 18 may be of any size as long as sufficient rigidity to protect the area near the crown of the wearer's head is ensured.
[0041] Near the front end (the side facing the wearer 100's face when worn; left side in Figure 5) and near the back end (right side in Figure 5) of the crown protection main body 18, roughly gourd-shaped screw insertion holes 20a and 20b, having a large diameter and a small diameter, are formed through the main body 18. Mounting screws 21a and 21b are installed in these screw insertion holes 20a and 20b. As shown in Figures 3 and 5, the crown protection part 13 and the covering part 12 are fixed together by the mounting screws 21a and 21b. By forming the screw insertion holes 20a and 20b in a roughly gourd shape, the wearer 100 can easily attach and detach the mounting screws 21a and 21b, and consequently attach and detach the crown protection part 13 and the covering part 12.
[0042] As shown in Figure 8, in this embodiment, the length L2 of the portion of the crown protection main body 18 that protrudes to the rear side of the peripheral protection portion 14 is longer than the length L1 of the portion that protrudes to the front side of the peripheral protection portion 14. Therefore, when the wearer 100 puts on the disaster prevention hood 10A, the wearer's face can be exposed from the front. However, the position of the peripheral protection portions 14, 14 relative to the crown protection main body 18 may be any position as long as the safety of the wearer's head 101 and good visibility are ensured when the wearer 100 is wearing the disaster prevention hood 10A.
[0043] The head protection portion 13 is positioned so that when the disaster prevention hood 10A is attached to the wearer's head 101, its longitudinal direction is along the front-to-back direction of the wearer's head 101, including the top of the wearer's head (the uppermost part of the wearer's head 101; for example, in Figure 10, this refers to the part facing the lower protection portion 8 and its vicinity; the same applies hereinafter in this specification). This makes it possible to protect a wide area, including the top of the wearer's head, from the impact of falling objects and penetration by protrusions.
[0044] The crown protection portion 13 may have any shape and be positioned in any location, as long as it can protect a wide area including the crown of the wearer's 100 head.
[0045] For example, the crown protection body 18 of the crown protection part 13 may be formed in a roughly columnar shape with thickness in the vertical direction, rather than being roughly plate-shaped. Also, the crown protection part 13 may be provided in a position along the left-right direction of the head 101 including the crown of the wearer 100, or it may be provided in a diagonal direction of the head 101 including the crown of the head. Furthermore, the crown protection part 13 may be provided in a position only in the front direction including the crown of the wearer 100, only in the back direction, only in the left direction, only in the right direction, etc. Also, the plan view shape of the crown protection body 18 may be any shape, such as an ellipse, a hexagon, or an octagon in plan view.
[0046] [Lower protection part] As shown in Figures 1 and 10, the lower protective portion 8 is attached to the bottom view side (the lower side when the wearer 100 is wearing it) of the crown protective main body 18. The lower protective portion 8 is made of a softer material than the crown protective main body 18, such as expanded polystyrene. However, it is desirable that the lower protective portion 8 has enough rigidity to suppress deformation and fracture of the crown protective main body 18 when it is struck by a falling object or protrusion, while also mitigating the impact on the wearer 100's head 101. For example, it is desirable that the rigidity of the lower protective portion 8 be lower than that of the crown protective main body 18, but higher than that of the covering portion 12.
[0047] Furthermore, the material of the lower protective part 8 is not limited to the expanded polystyrene mentioned above, but may be other foamed resins. Moreover, the lower protective part 8 is not limited to foamed resin, but may be formed from any polymer foam.
[0048] As shown in Figure 7, the lower protective portion 8 is roughly columnar in shape with thickness in the vertical direction, but is shorter in length than the crown protective main body portion 18 and has the same width as the crown protective main body portion 18. The lower protective portion 8 comes into contact with the crown of the wearer 100 and the vicinity of the crown of the wearer 100 when the wearer 100 is wearing it. The position and size of the lower protective portion 8 can be any position and size that can mitigate the impact on the crown of the wearer 100 when the crown protective portion 13 is subjected to an external impact.
[0049] The lower protective portion 8 may be attached to the crown protective body portion 18 in any manner. For example, one of the crown protective body portion 18 and the lower protective portion 8 may be provided with an engaging projection and the other with a recessed part that is engaged, or the crown protective body portion 18 and the lower protective portion 8 may be fixed together by adhesive, screws, or the like.
[0050] [Upper protective section] As shown in Figures 4 to 6, the helmet shell 4 is equipped with an upper protective section 7. The upper protective section 7 is attached to the top of the head protection section 13 in a plan view (the upper side when the wearer 100 is wearing it). The upper protective section 7 is made of a softer material than the main top protection section 18, such as expanded polystyrene. However, it is desirable that the upper protective section 7, like the lower protective section 8, has enough rigidity to suppress deformation and breakage of the main top protection section 18 when falling objects or protrusions collide with the top protection section 13, while mitigating the impact on the wearer 100's head 101. For example, it is desirable that the rigidity of the upper protective section 7 be lower than that of the main top protection section 18, but higher than that of the covering section 12.
[0051] Furthermore, the material of the upper protective part 7 is not limited to expanded polystyrene, but may be other foamed resins. Other foamed resins include, for example, polyurethane (PUR), polystyrene (PS), and polyolefins (mainly polyethylene (PE) and polypropylene (PP)). In addition, phenolic resin (PF), polyvinyl chloride (PVC), urea resin (UF), silicone (SI), polyimide (PI), melamine resin (MF), etc., may also be foamed to take advantage of their respective properties. Moreover, the upper protective part 7 is not limited to foamed resin, but may be formed from any polymer foam.
[0052] As shown in Figures 4, 5, and 6(a), (b), and (c), the upper protective portion 7 is formed in the shape of a rectangular parallelepiped with a length extending from one end to the other end of the crown protective main body portion 18.
[0053] The upper protective portion 7 may have any shape and be positioned in any location, as long as it covers at least a part of the main body portion 18 of the crown protective portion 13.
[0054] For example, the upper protective portion 7 is not limited to a length extending from one end to the other end of the crown protection main body 18, but may be any length in the longitudinal direction of the crown protection main body 18, such as only the longitudinal center of the crown protection main body 18, only one end in the longitudinal direction, only the longitudinal other end, or one end and the other end in the longitudinal direction. Furthermore, the upper protective portion 7 is not limited to a rectangular parallelepiped shape, but may be any three-dimensional shape as long as its longitudinal cross-sectional shape is semicircular, semielliptical, or a polygon cut in half.
[0055] The upper protective portion 7 is formed with a width W that covers the upper sides of both thin-walled hinges 17, 17 that pivotally support the peripheral protective portions 19, 19 relative to the top protective body portion 18. However, the upper protective portion 7 is not formed with a width W that covers the entire upper surface of both thin-walled hinges 17, 17, but rather with a width that covers at least a portion of the upper surface of the thin-walled hinges 17, 17. For example, the upper protective portion 7 may be formed with a width that covers the upper surface of one of the thin-walled hinges 17, 17, or it may be formed with a width and shape that covers a portion of the upper surface of one of the thin-walled hinges 17.
[0056] As shown in Figure 6(a), the upper protective portion 7 has a flat upper surface. As shown in Figure 6(b), the upper protective portion 7 has three fitting protrusions 71 on one end and three fitting protrusions 71 on the other end of the lower surface, which fit into the recesses 18b of the crown protection body portion 18. These three fitting protrusions 71 are of the same length, have approximately the same width as the recesses 18b formed along the longitudinal direction of the crown protection body portion 18, and are arranged at approximately the same interval as the arrangement interval of the protrusions 18a of the crown protection body portion 18. The upper protective portion 7 is positioned on the crown protection body portion 18 by fitting each of the three fitting protrusions 71 into the recesses 18b of the crown protection body portion 18. However, the number, shape, and arrangement position of the fitting protrusions 71 are not particularly limited, as long as they fit into the recesses 18b of the crown protection body portion 18.
[0057] As shown in Figures 6(b) and (c), wedge-shaped projections 72 are formed on both sides in the width direction of three fitting projections 71 on one end and the other end of the lower surface of the upper protective part 7. These wedge-shaped projections 72 are formed along the entire length in the longitudinal direction of the upper protective part 7. The width of the opposing inner surfaces of these wedge-shaped projections 72 is approximately the same as the width of the crown protection main body 18, so that each wedge-shaped projection 72 fits into the longitudinal side surface of the crown protection main body 18, and when the disaster prevention hood 10A is deployed, the tips of the wedge-shaped projections 72 bite into the space between the crown protection main body 18 and the peripheral protection main body parts 19, 19. However, the wedge-shaped projection 72 does not have to be formed along the entire length of the upper protective portion 7. If the width of the opposing inner surfaces of the wedge-shaped projection 72 is approximately the same as the width of the crown protective main body portion 18, the wedge-shaped projection 72 may be formed only partially along the length of the upper protective portion 7.
[0058] As shown in Figure 6(b), a flat contact recess 73 is formed on the lower surface of the upper protective portion 7 between the three fitting protrusions 71 on one end and the other end and the wedge-shaped protrusions 72 on both sides. This contact recess 73 contacts the upper surface of the crown protective portion 13 when the three fitting protrusions 71 are fitted into the recess 18b of the crown protective body portion 18.
[0059] To fix the upper protective part 7 to the upper side of the crown protection main body 18, as shown in Figure 5, one side of the double-sided adhesive tape 74 is adhered to the upper surface of the crown protection main body 18, and the contact recess 73 of the upper protective part 7 is adhered to the other side of the double-sided adhesive tape 74. By forming the lower surface of the upper protective part 7 in this way, one end and the other end in the longitudinal direction of the upper protective part 7 are positioned by the three fitting protrusions 71, the width direction of the upper protective part 7 is fixed by the wedge-shaped protrusions 72, and the contact recess 73 of the upper protective part 7 is fixed to the upper side of the crown protection part 13 by the double-sided adhesive tape 74.
[0060] The upper surface of the upper protective part 7 is provided with chamfered portions 75, where the four corners of the four sides of the rectangular parallelepiped are chamfered. The upper protective part 7 is integrally molded from a foamed resin such as expanded polystyrene, and includes a fitting projection 71, a wedge-shaped projection 72, a contact recess 73, and chamfered portions 75.
[0061] [Surrounding Area Protection Department] As shown in Figure 8, the helmet shell 4 is equipped with a pair of peripheral protection parts 14, 14. Each peripheral protection part 14, 14 comprises a peripheral protection main body 19, 19 and protectors 6, 6.
[0062] As shown in Figure 5, the peripheral protection body portion 19 of each peripheral protection portion 14 consists of a part of the helmet body portion 5.
[0063] Each peripheral protective body portion 19 is formed in a roughly rectangular shape in plan view, with both lower ends chamfered.
[0064] As shown in Figure 8, the protector 6 has substantially the same shape as the peripheral protection main body 19, and as shown in Figures 8 and 9, it is attached to the helmet body 5 on the plan view side of the helmet body 4.
[0065] As shown in Figure 7, the top protective body portion 18 of the protector 6 forms a hinge protection portion 25. As shown in Figure 7, the hinge protection portion 25 protrudes above the thin-walled hinge 17, preventing flying objects or protrusions from the outside from colliding with the thin-walled hinge 17.
[0066] As shown in Figure 8, the peripheral protection body 19 and the protector 6 are joined by inserting screws 22c, 22c. The peripheral protection part 14 and the headband 34, which will be described later as a "fastening part", are joined by inserting screws 27a, 27b as shown in Figures 8 to 10. The ends of the shock-absorbing parts 15, 16 shown in Figure 10 are fixed to the peripheral protection part 14 by screws 31, 31.
[0067] In the actual disaster prevention hood 10A, as shown in Figures 1 and 2, the headband 34 and the peripheral protection part 14 are joined together with screws 27a and 27b, as well as the crown contact part 9, which will be described later.
[0068] The peripheral protection section 14 comes into contact with or is close to the side of the wearer's head when the wearer 100 puts on the disaster prevention hood 10A, and functions to protect the side of the wearer's head and the area around it from falling or flying objects from the outside.
[0069] [Thin-walled hinge] As shown in Figure 7, a thin-walled hinge 17 is provided between the crown protection main body 18 and the peripheral protection main body 19. As shown in Figure 7, the thin-walled hinge 17 is formed to be thinner than both the crown protection main body 18 and the peripheral protection main body 19. The peripheral protection portion 14, including the peripheral protection main body 19, rotates along the longitudinal direction of the crown protection main body 18 at the thin-walled hinge 17. Each peripheral protection portion 14 is formed to be rotatable relative to the crown protection main body 18, depending on the change in shape of the disaster prevention hood 10A between the unfolded and folded states.
[0070] [Parietal contact part] As shown in Figures 1 and 2, a substantially rectangular head contact portion 9 is provided on the bottom side of the pair of peripheral protection portions 14, 14 in this embodiment. This head contact portion 9 is made of an elastic and flexible material, such as a double raschel fabric, and has screw insertion holes (not shown) at its four corners. Screws 27a and 27b are inserted into these screw insertion holes (not shown), and the head contact portion 9 is fixed to the peripheral protection portion 14 and the headband 34 by the screws 27a and 27b.
[0071] The crown contact portion 9 contacts the crown of the wearer 100's head or the area around the crown when the wearer 100 puts on the disaster prevention hood 10A. When the wearer 100 puts on the disaster prevention hood 10A, the crown contact portion 9 is sandwiched between the crown side of the wearer 100's head 101 and the lower protective portion 8 of the crown protection portion 13. At this time, the crown contact portion 9 is in close contact with a large area of the crown side of the wearer 100's head 101. The flexibility of the crown contact portion 9 provides the wearer 100 with a good fit and mitigates strong impacts applied to the wearer 100's head 101 from collisions with falling or flying objects. Furthermore, the frictional force exerted by the close contact between the crown contact portion 9 and the large area of the head 101 allows the wearer 100 to wear the disaster prevention hood 10A in a stable state with little displacement or wobbling.
[0072] [Impact mitigation section] As shown in Figures 2 and 10, horizontally elongated insertion holes 28a, 29a, 28b, and 29b are provided at corresponding positions on the front and back sides of the peripheral protection body 19 and the protector 6 that constitute the peripheral protection section 14. As shown in Figures 2 and 10, the shock-absorbing section 15 is inserted through the insertion holes 28a and 28b, and the shock-absorbing section 16 is inserted through the insertion holes 29a and 29b.
[0073] The shock-absorbing sections 15 and 16 are formed in a strip shape from a material that has flexibility and rigidity, such as synthetic fibers like polypropylene. Both ends of the shock-absorbing section 15 are fixed to the peripheral protective section 14 by screws 31, 31, and both ends of the shock-absorbing section 16 are fixed to the peripheral protective section 14 by screws 32, 32.
[0074] With this configuration, as shown in Figure 10, the pair of impact-absorbing sections 15 and 16 are arranged at both longitudinal ends of the crown protection section 13, spanning across the crown protection section 13. Furthermore, the impact-absorbing sections 15 and 16 are arranged to connect a pair of opposing peripheral protection sections 14 and 14 via the crown protection section 13.
[0075] The impact-absorbing sections 15 and 16 are connected to the peripheral protection section 14 at a position where they do not come into contact with the head 101 of the wearer 100 wearing the disaster prevention hood 10A. In this embodiment, the impact-absorbing sections 15 and 16 are connected to the lower front end (left side in Figure 10) and the rear end (right side in Figure 10).
[0076] The lengths of the impact-absorbing sections 15 and 16 connected to the peripheral protection section 14 are such that they are long enough to prevent the deployment of the peripheral protection section 14 at a position where the lower protection section 8 does not come into contact with the wearer's head 101. In other words, the impact-absorbing sections 15 and 16 maintain a state in which the lower protection section 8 does not come into contact with the top of the wearer's head when the peripheral protection sections 14 and 14 are tensed during deployment.
[0077] [Head circumference fastening part] As shown in Figures 1, 2, and 7, a pair of peripheral protection parts 14, 14 are connected to a head circumference fastening part 2. This head circumference fastening part 2 comprises a headband 34 as a "fastening part" and a lateral fastening cord 50.
[0078] [Headband] As shown in Figures 1 and 2, the headband 34 comprises a right-side member 35 located on the right side when viewed from the front, and a left-side member 36 located on the left side when viewed from the front. The right-side member 35 and the left-side member 36 are made of a synthetic resin, such as polyethylene or polypropylene, that has flexibility and rigidity and is resistant to stretching and loss of rigidity even with repeated or long-term use. However, they may be made of any material that has similar properties.
[0079] As shown in Figures 1 and 2, the left-side member 36 is provided with a strip-shaped temporal contact portion 37. When in use, this temporal contact portion 37 has its longitudinal direction substantially aligned with the horizontal direction and contacts the right temporal side of the head.
[0080] The side contact portion 37 has a front connecting piece 38 and a rear connecting piece 39 protruding upward. At the upper ends of the front connecting piece 38 and the rear connecting piece 39, there are roughly gourd-shaped upper retaining holes 40 and 41, which are formed by connecting a large diameter portion and a small diameter portion. Screws 27a and 27b are inserted into the upper retaining holes 40 and 41.
[0081] Furthermore, a downward connecting piece 42 is provided projecting downward from the side contact portion 37. A roughly gourd-shaped lower retaining hole 43, which connects a large diameter portion and a small diameter portion, is formed at the lower end of the lower connecting piece 42. A hollow screw 44, shown in Figures 1 and 2, is fitted into the lower retaining hole 43 (this hollow screw 44 will be described later).
[0082] As shown in Figures 1 and 2, the lower edge from the lower joining piece 42 to approximately the center of the temporal contact portion 37 forms an upwardly curved portion 45. The curved portion 45 is located above the insertion position of the hollow screw 44 and is formed at the position where the upper part of the base of the wearer's auricle 100 (see Figure 10) is positioned when the headband is worn. The effects of providing the curved portion 45 will be described later (see [(2) Effects based on the shape of the headband]).
[0083] Furthermore, as shown in Figures 3, 4, and 8, a narrowed section 46 is formed in the temporal contact portion 37 at the joints with the front joining piece 38, the rear joining piece 39, and the lower joining piece 42, where the width in the vertical direction is narrowed. The effects of providing this narrowed section 46 will be described later (see [(2) Effects based on the shape of the headband]).
[0084] On the outer side of the temporal contact portion 37, arch-shaped cord insertion portions 47a, 47b, 47c, 47d, 47e, and 47f are erected, opening in the front-to-back direction from the front side (left side as shown in Figures 3 and 6) to the rear side (right side as shown in Figures 4 and 7). In addition, a rear cord insertion hole 48 is formed at the rear end of the temporal contact portion 37. The lateral fastening cord 50, which will be described later, is inserted through these cord insertion portions 47a, 47b, 47c, 47d, 47e, and 47f, and the rear cord insertion hole 48.
[0085] An opening 49 for inserting a lower strap is formed at the lower end of the lower connecting piece 42. The chin strap 3, which will be described later, is inserted through these lower strap insertion holes 49.
[0086] The right-side member 35 also has a front joining piece 38, a rear joining piece 39, and a lower joining piece 42 protruding from it, similar to the left-side member 36. Upper holding holes 40 and 41 are formed in the front joining piece 38 and the rear joining piece 39, and a lower holding hole 43 is formed in the lower joining piece 42. In addition, the right-side member 35 also has string insertion parts 47a, 47b, 47c, 47d, 47e, and 47f erected on it, with a rear string insertion hole 48 and a lower string insertion hole 49 formed therein.
[0087] [Side fastening cord] As shown in Figures 1 and 2, the temporal contact portion 37 of the right-side member 35 and the temporal contact portion 37 of the left-side member 36 are connected by a lateral fastening cord 50. This lateral fastening cord 50 is formed in a strip shape from a highly rigid material, such as synthetic fibers like polypropylene.
[0088] As shown in Figure 1, a buckle 51 that allows for adjustment of the length of the lateral fastening cord 50 is attached to one end of the lateral fastening cord 50. The lateral fastening cord 50 is inserted through the cord insertion parts 47a, 47b, 47c, 47d, 47e and the rear cord insertion hole 48 of the right-side member 35, and through the cord insertion parts 47a, 47b, 47c, 47d, 47e and the rear cord insertion hole 48 of the left-side member 36, surrounding the forehead, temples, and back of the head of the wearer 100 when worn. The other end of the lateral fastening cord 50 is inserted through the buckle 51. By adjusting the length of the lateral fastening cord 50 with the buckle 51, the lateral fastening cord 50 is fastened to the wearer 100's head 101, and the fastening to the wearer 100's head 101 is also loosened.
[0089] [Chin strap] As shown in Figures 1 and 2, the chin strap 3 is fitted into the lower strap insertion hole 49 of the lower joining piece 42 of the right member 35 and the left member 36, respectively. The chin strap 3 is also formed in a strip shape from a highly rigid material, similar to the lateral fastening strap 50, such as a synthetic fiber like polypropylene.
[0090] The upper end of the chin strap 3 is inserted through the lower strap insertion hole 49 of the lower connecting piece 42 of the headband 34, folded back, and secured with a screw 53. The lower end of the chin strap 3 is folded back and secured with a screw 54.
[0091] A whistle 55 is attached to the lower end of the chin strap 3 on one side (the left side in Figure 1, and the right side in Figure 2). This whistle 55 can be used by the wearer 100 to alert those around them to danger or the wearer 100's presence when the wearer 100 is involved in an emergency or needs to call for help.
[0092] As shown in Figure 1, a connecting member 56 is provided in the middle of each chin strap 3,3. This connecting member 56 is formed in a substantially disc shape, with an engaging recess on one side (left side in Figure 1) and an engaging projection on the other side (right side in Figure 1). The chin straps 3,3 are connected by the engagement of this engaging projection and the engaging recess. Each connecting member 56 is designed to allow the chin strap 3 to slide from the upper end to the lower end and to be fixed at a desired portion on the chin strap 3.
[0093] Furthermore, the connecting member 56 does not need to be provided separately for each chin strap 3,3. A pair of chin straps 3,3 may be inserted through a single connecting member 56, which can function as a movable cord stopper on each chin strap 3,3. Alternatively, fastening members such as hook-and-loop fasteners may be directly provided on the chin straps 3,3, allowing them to be directly connected at a desired position. In addition, the connecting member 56 may be provided with connecting members other than the engaging recess and engaging protrusion, such as hook-and-loop fasteners, hooks, or clips.
[0094] [Covered part] As shown in Figures 1 and 2, the disaster prevention hood 10A of this embodiment includes a covering portion 12. The covering portion 12 covers almost the entire upper, both sides and back of the top protection portion 13, and extends downward from the top protection portion 13. As a result, the covering portion 12 covers the wearer's head 101, neck, and shoulders. The covering portion 12 may cover any portion below the wearer's head 101.
[0095] As shown in Figures 1 and 3, the covering portion 12 is formed by joining one end (upper side) and one side (rear side) of a roughly rectangular right member 57 and a roughly rectangular left member 58 with multiple screws, for example, three screws 59a, 59b, and 59c. This reduces the sewing process and simplifies manufacturing. One or more of the screws 59a, 59b, and 59c may also be equipped with a function for attaching a cloth name card (not shown) to easily identify the wearer 100 of the disaster prevention hood 10A from the outside. The one end (upper side) and one side (rear side) of the right member 57 and the left member 58 may be joined in any manner other than by the screws 59a, 59b, and 59c shown in Figure 1. For example, the one end (upper side) and one side (rear side) of the right member 57 and the left member 58 may be sewn together.
[0096] A pair of chin strap insertion parts 61, 61 are provided on the front side of the back surface of the covering part 12. The chin strap insertion parts 61, 61 are formed in an annular shape by fastening both ends of a strip-shaped member to the covering part 12 with mounting screws 65. The chin straps 3, 3 are inserted through the annular portions of the chin strap insertion parts 61, 61.
[0097] The covering portion 12 is softer and more cushioned than the crown protection portion 13, and is made of a roughly rectangular piece of fabric that is flame-retardant or has been treated to be flame-retardant (for example, flame-retardant polyester, or cotton or polyester treated with aluminum vapor deposition).
[0098] As shown in Figure 2, the front portion 12c of the covering part 12 has foamed resin sealed between two roughly rectangular pieces of fabric made of flame-retardant material or treated with flame-retardant processing.
[0099] These flame-retardant materials or flame-retardant treated fabrics include, for example, flame-retardant polyester, or cotton or polyester treated with aluminum vapor deposition. Foamed resin includes, for example, foamed polyester. By enclosing foamed resin in the covering part 12, impact resistance against falling objects can be enhanced.
[0100] On the other hand, as shown in Figure 2, the rear portion 12d of the covering part 12 is made of a roughly rectangular piece of flame-retardant material or flame-retardant treated fabric, but does not contain any foamed resin or the like. This prevents the wearer 100 from experiencing discomfort, such as feeling a stiff object on the back of their head, when wearing the disaster prevention hood 10A.
[0101] By forming the front portion 12c and rear portion 12d of the covering part 12 as described above, it is possible to enhance impact resistance to the top and sides of the head, etc., where the wearer 100 must maintain high protection against falling objects, while also obtaining a good fit.
[0102] The covering portion 12 is configured so that the upper portion 12a and the lower portion 12b can be folded to form a roughly rectangular mat. Specifically, for example, after joining the right member 57 and the left member 58 to form a flat shape, the boundary between the upper portion 12a and the lower portion 12b of the right member 57 shown in Figure 1 is valley-folded, and the upper portion 12a and the lower portion 12b of the left member 58 are mountain-folded to form the disaster prevention hood 10A as a roughly rectangular mat.
[0103] [Usage status] First, the case in which this embodiment of the disaster prevention hood 10A is used to protect the head 101 of the wearer 100 will be described below in (1) to (4).
[0104] [(1) Formation of the deployed state and attachment to the head] The wearer 100 expands the covering portion 12 of the folded disaster prevention hood 10A in the vertical direction. Specifically, the upper portion 12a and lower portion 12b of the right-side member 57, which is folded in a valley fold, and the upper portion 12a and lower portion 12b of the left-side member 58, which is folded in a mountain fold, so that both the right-side member 57 and the left-side member 58 are exposed and flat. Furthermore, the wearer 100 expands the right-side member 57 and the left-side member 58 of the covering portion 12 in the horizontal direction (see Figures 1 and 2). At this time, the headband 34 and the top of the head contact portion 9 also expand to the left and right along with the covering portion 12. As a result, the disaster prevention hood 10A is in the expanded state shown in Figures 1 and 2.
[0105] In this state, as shown in Figure 11, the wearer 100 puts the disaster prevention hood 10A on their head 101. At this time, the headbands 34, 34 curve in the direction indicated by arrow D in Figure 11 to form a three-dimensional shape that conforms to the circumference of the head 101. The wearer 100 then connects the engaging recesses and engaging protrusions of the connecting members 56, 56 of the pair of chin straps 3, 3. Furthermore, the connecting members 56, 56 are pulled up towards the upper end. This fastens the chin straps 3, 3 to the wearer 100's chin. The temporal contact portion 37 of the headband 34 of the disaster prevention hood 10A is then fixed from the wearer 100's forehead through the temporal region to the back of the head. In addition, the lateral fastening straps 50 are fastened and fixed from the wearer 100's forehead through the outside of the temporal contact portion 37 to the back of the wearer's head. Furthermore, the crown contact portion 9 of the disaster prevention hood 10A undergoes elastic deformation. Then, the crown contact portion 9 changes from a flat state, as shown by the dashed line at the bottom of Figure 11, to a curved state, as shown by the dashed line at the top, that conforms to the head 101. In this state, the crown contact portion 9 is fixed in contact with and secured to a wide area of the crown of the wearer's 100 head and its vicinity.
[0106] This ensures that the disaster prevention hood 10A is firmly fixed to the wearer's head 101 in a way that prevents it from shifting position or falling off. The head protection main body 18 is provided spaced apart and facing each other from the top of the wearer's head 101 in the front-to-back direction, and the peripheral protection parts 14 are provided around the top of the head. The head protection main body 18 and the peripheral protection parts 14 work together to mitigate the impact when falling objects hit the top of the head and its surrounding areas, and to prevent penetration of the head 101 when protruding objects hit it.
[0107] As shown in Figure 11, gaps 62 are formed on both sides of the main head protection body 18. However, the size of the gaps 62 (the distance from the wearer's head 101 to the inside of the peripheral protection part 14) is greater than or equal to the thickness 63 of the peripheral protection part 14. Therefore, even if a protrusion collides with and penetrates the gap 62, it is possible to prevent that protrusion from reaching the wearer's head 101.
[0108] [(2) The effect of the headband shape on the wearer] As shown in Figures 8 and 9, a narrowed portion 46 is formed in the part of the headband 34 where the temporal contact portion 37 connects to the front connecting piece 38, the rear connecting piece 39, and the lower connecting piece 42.
[0109] Normally, the portion of the headband 34 where the temporal contact portion 37 connects to the front connecting piece 38, the rear connecting piece 39, and the lower connecting piece 42 is wider and more rigid, making it difficult to bend the headband 34 even when force is applied to this portion. However, the narrow portion 46 of the headband 34 in this embodiment is narrower and less rigid than other parts of the headband 34, making it easier to bend when force is applied. Therefore, when the disaster prevention hood 10A is attached to the head 101 of the wearer 100, the portion of the headband 34 where the temporal contact portion 37 connects to the front connecting piece 38, the rear connecting piece 39, and the lower connecting piece 42 can be easily bent into a three-dimensional shape that substantially conforms to the three-dimensional shape of the wearer 100's head 101. As a result, the headband 34 can form a disaster prevention hood 10A that provides the wearer 100 with a good fit.
[0110] Furthermore, the lower edge of the headband 34, from the lower connecting piece 42 to approximately the center of the temporal contact portion 37, forms an upwardly curved portion 45.
[0111] Here, when the hollow screw 44 inserted into the headband 34 is positioned near the wearer's ear canal 103 (see Figure 11), the upper part of the base of the wearer's auricle 100 (see Figure 11) is positioned at the curved portion 45. The curved shape of the curved portion 45 then fits the curved shape of the upper part of the base of the auricle 102. In other words, the part of the headband 34 from the lower connecting piece 42 to the temporal contact portion 37 does not come into contact with the wearer's earlobe, so the wearer does not feel any pain from the headband 34 coming into contact with their earlobe.
[0112] Furthermore, the headband 34 should contact the wearer 100's head 101 at the lowest possible position to provide the wearer 100 with a sense of stability. As shown in Figure 7, the headband 34 in this embodiment has a curved portion 45. Therefore, compared to the case where there is no curved portion 45 and the lower edges of the temporal contact portion 37 and the lower connecting piece portion 42 are formed in a nearly straight line, the temporal contact portion 37 and the lower connecting piece portion 42 can contact the wearer 100's head 101 at a relatively low position on the side. This makes it easier to get the feeling that the headband 34 is worn deeply, and the wearer 100 can obtain a good fit.
[0113] Furthermore, the temporal contact portion 37 and the lower connecting piece 42 of the right-side member 35 and the left-side member 36 may be configured in any shape as long as they provide a good fit to the wearer 100.
[0114] [(3) The effect of the crown protection and impact-absorbing parts against falling objects, flying objects, protrusions, etc.] Consider a scenario during a disaster where a wearer 100 is wearing a disaster prevention hood 10A, and a falling or flying object flies in from outside the disaster prevention hood 10A and collides with the hood 10A.
[0115] Figure 12(a) schematically shows the state in which a falling object collides with a conventional interior material, and (b) schematically shows the state in which a falling object collides with an interior material according to an embodiment of this invention.
[0116] As shown in Figure 12(a), when a falling object 111 hits the conventional interior material 110, a strong impact force F1 is applied mainly downwards. Due to this impact force F1, the lower protective part 108 of the crown protection part 113 comes into contact with the wearer's head 100, and the crown protection main body 118 and the lower protective part 108 bend significantly so as to become convex downwards. As a result, the strong impact of the weight of the falling object suddenly hitting the wearer's head 101 causes significant damage to the head 101.
[0117] In this embodiment, as shown in Figure 12(b), a strong impact force F1 is applied to the interior material 11 mainly downwards by the impact of the falling object 111. However, this impact force F1 is absorbed and dispersed by the elastic deformation of the upper protective part 7. As a result, the strong impact force F1 is mitigated, and damage to the head 101 can be reduced.
[0118] Next, consider the case where, during a disaster, a wearer 100 is wearing a disaster prevention hood 10A when a pointed object flies in from outside the disaster prevention hood 10A and collides with it.
[0119] Figure 13(a) schematically shows a state in which a protrusion collides with a conventional interior material, and (b) schematically shows a state in which a protrusion collides with an interior material according to an embodiment of this invention.
[0120] As shown in Figure 13(a), when a protrusion 112 collides with the conventional interior material 110, a strong piercing force F2 is applied, mainly downwards. This piercing force F2 could potentially destroy the main head protection body 118 and the lower protection body 108, causing damage to the head 101.
[0121] In this embodiment, as shown in Figure 13(b), a strong piercing force F2 is applied downward to the interior material 11 by the impact of the protrusion 112, but this piercing force F2 is received and absorbed by the upper protective part 7. As a result, the protrusion 112 is prevented from penetrating, and damage to the head 101 is reduced.
[0122] Furthermore, in this embodiment, the upper protective portion 7 is formed to cover the upper side of the thin-walled hinges 17, 17 that pivotally support the peripheral protective portions 14, 14 relative to the top protective portion 13. This prevents flying objects, falling objects, and protrusions from colliding with the thin-walled hinges 17, 17, thereby preventing the thin-walled hinges 17, 17 from being damaged.
[0123] Furthermore, due to the configuration and operation of the lower protective section 8 and impact mitigation sections 15 and 16 as described above, even if the weight of falling objects or protrusions or the impact of flying objects collide with the disaster prevention hood 10A from the outside, the impact of the collision is mitigated at the contact section 64 (see Figure 11) between the lower protective section 8 of the disaster prevention hood 10A and the wearer's head 101 (with the crown contact section 9 in between).
[0124] As a result, the wearer's head 101 is protected from the impact of falling objects, flying objects, etc. by the lower protective part 8 and impact absorbing parts 15, 16 of the top protective part 13 of the disaster prevention hood 10A.
[0125] In this disaster prevention hood 10A, a head contact portion 9, as shown in Figures 1 and 2, is interposed between the lower protective portion 8 and the wearer's head 101. The elasticity of this head contact portion 9 also helps to mitigate the impact of collisions with falling or flying objects.
[0126] [(4) Formation of a folded state and use as a mat] Next, we will explain the case where the disaster prevention hood 10A worn by wearer 100 is used as a mat.
[0127] The wearer 100 pulls down the connecting members 56, 56 towards the lower ends of the chin straps 3, 3 and removes the disaster prevention hood 10A from their head. Next, the wearer 100 narrows and folds the right member 57 and the left member 58 of the covering part 12 of the disaster prevention hood 10A in the left-right direction. This makes the covering part 12 and the interior material 11 flat. Next, the wearer 100 folds the covering part 12 of the disaster prevention hood 10A in the up-down direction. Specifically, the boundary between the upper part 12a and the lower part 12b (see Figure 1) of the right member 57 of the covering part 12 is valley-folded, and the boundary between the upper part 12a and the lower part 12b (see Figure 1) of the left member 58 is mountain-folded. As a result, the disaster prevention hood 10A is folded into a flattened state that is roughly rectangular in plan view. In this state, the disaster prevention hood 10A functions as a comfortable seating surface due to the cushioning of the covering portion 12. That is, the wearer 100 can place the disaster prevention hood 10A on the floor or other surface at the evacuation site and sit comfortably.
[0128] For example, if the user of the Disaster Prevention Hood 10A is a child, such as an elementary school student, and they carry it folded in their school bag, the Disaster Prevention Hood 10A can be made more convenient for the user by folding it in this way and making the folded size approximately the same as a notebook or textbook used at school (for example, close to A4 size).
[0129] Furthermore, in this embodiment of the disaster prevention hood 10A, when the wearer 100 uses it while sitting, for example, by placing the folded lower portion 12b of the covering part 12 under their buttocks, they can obtain a comfortable seating experience with high elasticity. However, the wearer 100 can also sit on the folded upper portion 12a of the covering part 12.
[0130] Furthermore, when the wearer 100 uses the folded disaster prevention hood 10A by placing it on a chair, a comfortable sitting position can be obtained by placing the lower part 12b of the covering portion 12 under the buttocks and using the upper part 12a as a backrest. However, the wearer 100 can also sit on the folded upper part 12a of the covering portion 12 and use the folded lower part 12b as a backrest.
[0131] [Effects and Effects] As described above, in this embodiment, by providing a hard crown protection part 13 located at least on the top of the wearer's head and provided on the upper side of the head 101, it is possible to prevent the top of the wearer's head from being hit by an impact from a falling object or being pierced by a protrusion.
[0132] Furthermore, by providing a rigid peripheral protection section 14, it is possible to prevent the wearer 100 from being struck by falling objects or impaled by protrusions around the top of their head. In addition, by changing the position of the peripheral protection section 14 relative to the top of the head protection section 13 by rotating the thin hinge 17, the shape of the interior material 11 can be freely changed between an unfolded state and a folded state. Moreover, the upper protection section 7, which is provided to cover at least a portion of the upper side of the top of the head protection section 13 and is formed in a three-dimensional shape from a softer material than the top of the head protection section 13, can mitigate the impact on the wearer 100's head 101 even if a large flying object or heavy falling object 111 or a protrusion 112 falls. This makes it possible to provide a head protection device that can mitigate the impact on the head 101 caused by collisions with flying objects, falling objects 111 or protrusions 112.
[0133] In this embodiment, the upper protective portion 7 is formed to cover at least a portion of the upper side of the thin hinges 17, 17 that pivotally support the peripheral protective portions 14, 14 relative to the crown protective portion 13. This prevents flying objects, falling objects 111, and protrusions 112 from colliding with the thin hinges 17, 17, thereby enhancing safety.
[0134] In this embodiment, the upper protective portion 7 is formed to be thicker than the top protective portion 13, thereby reliably mitigating the impact on the head 101 caused by flying or falling objects 111 or protrusions 112.
[0135] In this embodiment, the upper protective portion 7 is integrally formed from foamed resin, thereby reliably mitigating the impact on the head 101 caused by flying objects, falling objects 111, or protrusions 112.
[0136] In this embodiment, a recess 18b is provided on the upper surface of the crown protection body 18 of the crown protection part 13, while a fitting projection 71 that fits into the recess 18b is provided on the lower surface of the upper protection part 7. As a result, the fitting projection 71 of the upper protection part 7 fits into the recess 18b of the crown protection body 18 of the crown protection part 13, preventing the upper protection part 7 from shifting position or becoming detached from the crown protection part 13. This ensures that impacts to the head 101 caused by flying or falling objects 111 or protrusions 112 are always reliably mitigated, improving reliability.
[0137] In this embodiment, the lower protective part 8 is provided below the top protective part 13, which further reliably mitigates the impact on the head 101 caused by flying objects, falling objects 111, or protrusions 112.
[0138] In this embodiment, the upper protective portion 7 has chamfered portions 75 formed on all four sides of its rectangular parallelepiped-shaped upper surface, thereby preventing damage to the covering portion 12 that covers at least the head 101 of the wearer 100 from the upper surface of the upper protective portion 7.
[0139] In this embodiment, the foldable hood, equipped with an interior material 11, protects the wearer's 100 head from impacts by falling objects 111 and penetration by protrusions 112 when unfolded, while the covering portion 12 protects the wearer's entire head from flying objects and heat. Furthermore, the covering portion 12 can be used as a cushioning mat when folded. In the event of a disaster evacuation, the wearer 100 can fold the head protection device and use it as a mat, allowing them to sit comfortably regardless of the hardness or unevenness of the floor surface. This reduces the impact on the head 101 from collisions with flying objects, falling objects 111, and protrusions 112, and provides a head protection device that allows the wearer 100 to sit comfortably after evacuation.
[0140] [others] In the above embodiment, the impact-absorbing parts 15 and 16 of the interior material 11 are provided in pairs on the front side (left side in Figure 10) and the back side (right side in Figure 10) of the crown protection part 13, but the embodiment is not limited to this. That is, the impact-absorbing parts 15 and 16 can be any configuration that can suppress or mitigate the impact of the lower protection part 8 colliding with the crown of the wearer 100 due to the force applied by falling objects, protrusions, or flying objects causing the peripheral protection parts 14, 14 of the disaster prevention hood 10A to deploy too far.
[0141] For example, in the above embodiment, the interior material 11 may be configured such that only one of the impact-absorbing parts 15 or 16 is provided. Alternatively, in addition to the impact-absorbing parts 15 and 16, further impact-absorbing parts may be provided, so that one disaster prevention hood 10A is provided with three or more impact-absorbing parts. Furthermore, at least one of the impact-absorbing parts 15 or 16 may be provided closer to the center (closer to the top of the wearer's head 100) rather than at the end of the top of the head protection part 13.
[0142] Furthermore, in the above embodiment, the impact-absorbing portions 15 and 16 of the interior material 11 are configured to span the lower side of the crown protection portion 13 and connect the peripheral protection portions 14 and 14. Alternatively, the impact-absorbing portions 15 and 16 of the interior material 11 may be configured to span the upper side of the crown protection portion 13 and connect the peripheral protection portions 14 and 14.
[0143] Furthermore, the interior material 11 in the above embodiment may have a configuration other than one in which the impact-absorbing parts 15 and 16 connect a pair of peripheral protection parts 14 and 14. For example, at least one of the impact-absorbing parts 15 and 16 may be connected to the crown protection part 13, thereby preventing the peripheral protection parts 14 and 14 from opening beyond a predetermined angle relative to the crown protection part 13.
[0144] In the above embodiment, the head contact portion 9 is configured to be sandwiched between the lower protective portion 8 of the head protection portion 13 and the head 101 of the wearer 100 when the disaster prevention hood 10A is worn, but the invention is not limited to this configuration. For example, the disaster prevention hood 10A can be configured such that the head contact portion 9 contacts the head 101 of the wearer 100, but the lower protective portion 8 of the head protection portion 13 does not contact the head contact portion 9 (i.e., a gap is formed between the lower protective portion 8 and the head contact portion 9 at the position of the contact portion 64 in Figure 11). By configuring it in this way, the impact of falling or flying objects on the head 101 of the wearer 100 can be further reduced. Furthermore, in the disaster prevention hood 10A of this embodiment, the head contact portion 9 can be omitted to simplify the configuration and prevent bulkiness when folded.
[0145] In the above embodiment, the head protection device is a disaster prevention hood 10A, but it is not limited to this, and may also be a fire hood, a gas hood, a dust hood, a helmet shell for various uses such as construction, sports, riding, police, or firefighting.
[0146] It goes without saying that the above embodiments are illustrative examples of the present invention and do not mean that the present invention is limited to the above embodiments. [Explanation of Symbols]
