Description

[Technical Field]

[0001] The present invention relates to a hat interior material used for hats such as helmets and work caps, and to a hat equipped with a hat interior material. [Background technology]

[0002] Helmets, work caps, and other types of headwear are often used while fastened to the wearer's head. In particular, headwear such as helmets, which are designed to protect the head from falling or flying objects, must be fastened to the wearer's head due to their intended purpose of protecting the head.

[0003] Conventionally, as means for fastening a hat such as a helmet to the wearer's head, there have been known chin strap rear hangers that include a chin strap rear hanger main body with strap holes on the left and right for hanging the left and right chin straps of the hat, and two sliding or holding pieces that are tiltably provided on the chin strap rear hanger main body for attachment to the inside rear of the helmet, and hats equipped with such chin strap rear hangers (see, for example, Patent Document 1).Also known is an interior material for a hat in which an elastic band is interposed in part of a band main body made of a non-elastic resin molded body that constitutes a headband (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-88414 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-138039 Summary of the Invention [Problem to be solved by the invention]

[0005] When using a headgear such as a helmet during a disaster such as an earthquake or fire, or during evacuation, the headgear must be fastened to the wearer's head to protect the wearer's head. This fastening of the headgear must be done quickly and accurately during a disaster or evacuation. However, the headgears described in Patent Documents 1 and 2 require a complicated donning process, since the wearer must first put the headgear on and then adjust the length of the chin strap and then fasten the adjusted chin strap to secure the headgear to the wearer's head. This can be particularly burdensome for people who are not adept at delicate tasks with their fingers, such as young children, the elderly, and physically disabled people, as well as for the guardians and caregivers who help them put on the headgear. Therefore, the inventions described in Patent Documents 1 and 2 have the problem that it can be difficult to quickly and accurately protect the heads of victims and evacuate them during a disaster or evacuation.

[0006] The present invention has been made in consideration of the above problems, and aims to provide an interior material for a hat, and a hat, which can be quickly and accurately fixed to the head when in use without requiring delicate finger movements. [Means for solving the problem]

[0007] In order to achieve this object, the invention described in claim 1 is an interior material for a hat for fastening various hats to the head of a wearer, comprising: a top-side member that abuts at least the top of the head of the wearer wearing the hat; a peripheral protection member that is fastened around at least the periphery of the head of the wearer; and string parts that are connected to the peripheral protection member and fastened around at least the ears of the head, wherein the top-side member has a top-holding part that holds down the top of the head of the wearer and a plurality of extension pieces that extend from the top-holding part, and the peripheral protection member comprises a peripheral member made of one or more members that is attached in the circumferential direction of the head of the wearer, and a string part that extends above the peripheral member. and a joining piece portion extending in a band shape toward the wearer's head, a gap portion is formed adjacent to the surrounding member in the circumferential direction of the head, at least a portion of the string portion is formed from an elastic member and is arranged to be hung across the surrounding member through the gap portion, the extension piece portion of the surrounding protection member is attached to the top side member at its upper end side, when the hat is worn on the head of the wearer, the surrounding member of the surrounding protection member is fastened to the head of the wearer by the elastic force of the string portion, and when the hat is not worn on the head of the wearer, the tension of the string portion is in a looser state than when the hat is worn on the head of the wearer.

[0008] The invention described in claim 2 is characterized in that, in addition to the configuration described in claim 1, the string portion comprises a pair of ear straps that are attached to the ear portions of the head, and a chin strap that is connected to each of the ear straps and attached to the chin portion of the head, and the chin straps and / or the ear straps are formed from the elastic material.

[0009] The invention described in claim 3 is characterized in that, in addition to the configuration described in claim 2, a pair of chin straps are provided, each of which is connected to the left ear strap and the right ear strap, and the end of the left chin strap and the end of the right chin strap are each connected to an adjuster that connects the chin straps and adjusts the length of the chin straps, and by adjusting the length of the chin strap with each adjuster and connecting the adjusters, the pair of chin straps are connected and fixed to the chin part of the head.

[0010] The invention described in claim 4 is characterized in that, in addition to the configuration described in claim 1, the top-side member is a hammock for fastening the hat main body to the top of the head, and the hammock is pressed against the top of the head and fixed in place by the tension of the string portion.

[0011] The invention described in claim 5 is a hat comprising a hat main body portion for protecting the head, which constitutes the hat, and an interior material for a hat described in any one of claims 1 to 4, which is arranged inside the hat main body portion. [Effects of the Invention]

[0012] According to the invention of claim 1, at least a portion of the strings constituting the hat interior material, which are fastened at least from the ears to the chin, are formed of an elastic material. Therefore, when the strings are placed around the ears and around the chin with the hat main body on the wearer's head, the strings are immediately secured around the ears and around the chin due to elastic deformation of the strings. Furthermore, since the strings are arranged to be stretched across the peripheral member of the peripheral protective member via a gap, when the strings are placed around the ears and around the chin, a downward tension acts on the strings, which draws the peripheral member closer in the gap, immediately securing the peripheral protective member to the wearer's head. Furthermore, the extension piece of the peripheral protective member is attached at its upper end to the crown-side member. When the hat is worn on the wearer's head, the peripheral member of the peripheral protective member is fastened to the wearer's head by the elastic force of the strings. When the hat is not worn on the wearer's head, the tension of the strings is looser than when the hat is worn on the wearer's head. Therefore, the hat interior material and the hat body main body can be quickly and easily fixed to the heads of a variety of wearers, including when the wearer puts the hat on themselves, and when a guardian or caregiver puts the hat on another wearer, including an infant, an elderly person, or a physically disabled person. The hat interior material can be quickly and easily fixed to the heads of a variety of wearers who use hats, not only in normal times but also in emergencies such as disasters. This allows the hat interior material to be quickly and accurately fixed to the head when in use, without requiring delicate finger manipulation.

[0013] According to the invention of claim 2, the chin strap and / or ear straps constituting the strings are made of an elastic material, so that when the strings are fastened around the ears to the chin during use, the strings are immediately fastened around the ears to the chin by the elastic deformation and tension of the strings, and the hat body is immediately fastened to the wearer's head. This allows the hat interior material to be reliably fastened to the head during use without requiring delicate finger manipulation.

[0014] According to the invention described in claim 3, a pair of chin straps are provided, each connected to a left ear strap and a right ear strap. This allows the chin straps to be separated into left and right halves, allowing the hat to be stored or transported without bulking up the straps. Furthermore, the ends of the left and right chin straps are connected to each other, respectively, and are provided with adjusters that connect the chin straps and adjust their lengths. By adjusting the length of the chin straps with the adjusters and connecting the adjusters, the pair of chin straps are connected and secured to the chin area of ​​the head, allowing the chin strap length to be freely adjusted to fit the wearer's head and worn on the head. Therefore, the hat interior material can be fitted to the wearer's head regardless of differences in head size. Furthermore, by adjusting the length of the chin straps with the adjusters in advance, the hat interior material can be fitted to the wearer's head more quickly and easily, not only in normal times but also in emergencies such as disasters. Furthermore, the hat interior material can be fitted to the heads of a variety of wearers, including when the wearer puts the hat on themselves, and when a guardian or caregiver puts the hat on another wearer, including an infant, the elderly, or the physically disabled, etc. This allows the hat interior material to be more securely fixed to the head when in use, without requiring delicate finger manipulation.

[0015] According to the invention of claim 4, the hammock for fastening the hat to the top of the head is pressed against the top of the head by the tension of the strings, thereby fixing the hat interior material to the top of the wearer's head. This allows the hat interior material to be reliably fixed to the wearer's head, including the top of the head, without requiring delicate finger manipulation during use.

[0016] According to the invention as set forth in claim 5, a hat can be provided that can be fastened to the head quickly and accurately without requiring delicate finger movements when in use. [Brief explanation of the drawings]

[0018] An embodiment of the present invention will now be described with reference to the drawings.

[0019] 1 to 17 show an embodiment of the present invention.

[0020] Helmet 1A as the "head" of this embodiment shown in FIG. 1 is a construction helmet, a helmet for various types of work, or a disaster prevention helmet, and is used to protect the wearer's head from impacts such as falling objects. The wearer here may be a person who puts on helmet 1A themselves, such as a healthy child or adult. The wearer here may also be a person who puts on helmet 1A with the assistance of a parent or caregiver, such as an infant, elderly person, or physically disabled person.

[0021] As shown in FIG. 1, this helmet 1A comprises a helmet shell 1 as a "hat main body" and an interior material 2 disposed inside this helmet shell 1 as a "hat interior material."

[0022] The helmet shell 1 is integrally molded from a highly rigid resin such as ABS, etc. The helmet shell 1 can be colored and opaque, colored and transparent, or colorless and transparent.

[0023] As shown in Figures 4 to 8, the helmet shell 1 is formed into a shape that covers the head by combining multiple flat plate-like portions formed into a polygonal shape. In this embodiment, each flat plate-like portion is formed into a triangular or hexagonal shape and has a different shape and area. For example, the front head protection member 3 that covers the wearer's forehead and the front end visor portion 4 are formed into a generally hexagonal or generally rectangular shape and have a relatively large area, the front side head protection members 5, 6, 7, and 8 are formed into a generally triangular shape and have a relatively large area, and the parietal protection members 9, 10, 11, 12, and 13 that protect the area around the top of the head are formed into a generally triangular shape and have a relatively small area. On the other hand, a vertex 14 is formed in an area where increased protection is desired, for example, in the area of ​​the parietal surrounded by the parietal protection members 9, 10, 11, 12, and 13. As shown in Figures 4 and 5, the helmet shell 1 is formed symmetrically.

[0024] As shown in Figures 3, 4, and 6, front mounting protrusions 17, 18 are provided to protrude from portions of the helmet body 1 that straddle the front head protection members 6, 8 and the temporal head protection members 15, 16 located directly below them. As shown in Figures 4, 5, and 7, rear mounting protrusions 21, 22 are provided to protrude from the rear temporal protection members 19, 20. As shown in Figure 8, the front mounting protrusions 17, 18 are generally rectangular in front view, and as shown in Figure 4, the upper surface is formed in a flat shape that slopes downward toward the front. On the other hand, as shown in Figures 4 and 8, the rear mounting protrusions 21, 22 are formed in a generally triangular pyramid shape in front view, and as shown in Figure 4, the upper surface is formed in a generally horizontal flat shape. As will be described later, when multiple identical helmets 1A are stacked, the lower part of the headband main body (described later) that forms the helmet wearing device 2a of the other helmet 1A stacked on top is placed on the front mounting protrusions 17, 18 and the rear temporal protection members 19, 20.

[0025] 5, fitted portions 23, 24, 25, and 26 are provided at four locations inside the helmet body 1. Four fitting pieces 35, 35, 35, and 35 (see FIG. 2, described later) provided on the helmet wearing device 2a are fitted into these fitted portions 23, 24, 25, and 26, respectively.

[0026] The number of mounting protrusions 17, 18, 21, 22 may be more or less than four as long as it is suitable for stacking a plurality of helmets 1A (see FIG. 17).

[0027] On the other hand, as shown in Figs. 9 and 11, the interior material 2 is made up of a helmet wearing device 2a and a string part 2b.

[0028] As shown in FIGS. 9, 10, and 11, the helmet wearing device 2 a includes a hammock 30 and a headband 31 .

[0029] The hammock 30 is made of a synthetic resin, such as polyethylene, that is flexible and rigid and does not easily stretch or lose rigidity even with repeated or long-term use. However, any material with similar properties may be used. The hammock 30 has a head support portion 33 that supports the top of the wearer's head, and four generally band-shaped extension pieces 34 extending from the head support portion 33. A fitting piece 35 is provided at the tip of each extension piece 34, protruding in the width direction of the extension piece 34. These four fitting pieces 35, 35, 35, 35 are fitted into fitting portions 23, 24, 25, 26 inside the helmet shell 1 shown in FIG. 5, respectively, thereby forming a state in which the helmet wearing device 2a is disposed inside the helmet shell 1 as shown in FIG. 2.

[0030] On the other hand, the headband 31 is made up of a belt-shaped headband main body 32 that continues in the circumferential direction of the head and gaps (described later) formed at two locations between the headband main body 32.

[0031] The headband main body 32 is made of the same material as the hammock 30. The headband main body 32 is made up of a front member 36 as a "surrounding member" disposed on the front side of the wearer's head, and a rear member 37 as a "surrounding member" disposed on the back side of the wearer's head.

[0032] Furthermore, the headband main body 32 is disposed so as to surround the periphery of the wearer's head when the helmet 1A is worn on the head. Specifically, as shown in Fig. 2, the front member 36 and the rear member 37 are continuous in a band shape so as to abut in the circumferential direction of the head when the helmet 1A is worn on the wearer's head, that is, from the wearer's forehead to both sides of the head, and from the back of the wearer's head to both sides of the head, respectively.

[0033] The lower portions of both end portions of the front member 36 are generally arc-shaped and convex downward (see Figures 11 and 15), while the lower portions of both end portions of the rear member 37 are generally linear (see Figures 11 and 15).

[0034] Gaps are formed at two locations between the front member 36 and the rear member 37. That is, as shown in Fig. 2, a left-head-side gap 38 is formed as a "gap" adjacent to the position of the wearer's left head between one end of the front member 36 and the other end of the rear member 37. Also, a right-head-side gap 39 is formed as a "gap" adjacent to the position of the wearer's right head between the other end of the front member 36 and one end of the rear member 37.

[0035] Front joining pieces 40, 40 and rear joining pieces 41, 41 are provided on one end and the other end of the front member 36, and on one end and the other end of the rear member 37, respectively. These joining pieces 40, 40, 41, 41 are rotatably connected to the respective extension pieces 34, 34, 34, 34 with screws (not shown). This allows the headband 31 to be continuous with a portion of the hammock 30. Note that instead of this embodiment, the headband 31 and the hammock 30 may be integrally formed, allowing the headband 31 to be continuous with a portion of the hammock 30.

[0036] Vertically elongated insertion holes 42, 42 and insertion holes 43, 43 are formed through both end portions of the front member 36 and both end portions of the rear member 37. Ear straps 46, 46 are inserted through the insertion holes 42, 42 and the insertion holes 43, 43.

[0037] 1, 9, 10, etc., the string portion 2b includes a pair of ear straps 46, 46 and a pair of chin straps 47, 47. The left ear strap 46 is inserted into the left insertion holes 42, 43, and the right ear strap 46 is inserted into the right insertion holes 42, 43, respectively, thereby connecting the front member 36 and the rear member 37 of the headband 31 on the left and right sides.

[0038] In this embodiment, the ear straps 46, 46 are formed of an elastic string-like member, such as a rubber string.

[0039] Each ear strap 46 is inserted through the insertion hole 42 of the front member 36 and then through the insertion hole 43 of the rear member 37. Both ends of the ear strap 46 are connected to the ear strap buckle 44. The ear strap 46 is generally circular and is attached to the wearer's ear. When worn, the ear strap 46 may or may not contact the wearer's ear. Alternatively, at least a portion of the ear strap 46 may be attached to the surface of the wearer's ear or may cover the ear. As a result, as shown in FIG. 11 , the ear straps 46 connect the ends of the front member 36 and the rear member 37 (one end of the front member 36 to the other end of the rear member 37, and the other end of the front member 36 to one end of the rear member 37).

[0040] On the other hand, the chin straps 47, 47 are formed in a strip shape from a highly rigid fiber such as polypropylene. The end of the chin strap 47 on the base end side is folded back and fixed with a rivet 54 to form a ring portion 55. The ear strap 46 is inserted into the inside of this ring portion 55, connecting the chin strap 47 and the ear strap 46.

[0041] An engaging member 49 and an engaged member 50 that constitute a chin strap buckle 48 serving as an "adjuster" are connected to the distal end of each of the chin straps 47, 47. As shown in Fig. 1, the chin strap buckle 48 has a string-passing portion 51 through which one of the chin straps 47 is inserted. The chin strap buckle 48 can adjust the length of the chin strap 47 by moving the position of the chin strap buckle 48 relative to the chin strap 47 at the string-passing portion 51.

[0042] It is sufficient that the string portion 2b as a whole has elasticity that allows elastic deformation and rigidity that allows the helmet 1A to be secured to the head. Therefore, contrary to this embodiment, the chin straps 47 may be made of an elastic material such as a rubber strap, and the ear straps 46 may be made of a highly rigid fiber. Also, both the ear straps 46 and the chin straps 47 may be made of an elastic material. Furthermore, the ear straps 46 and the chin straps 47 on one side, e.g., the right side, may be made of an elastic material, and the ear straps 46 and the chin straps 47 on the other side, e.g., the left side, may be made of a highly rigid fiber. Furthermore, the ear straps 46 and the chin straps 47 may be made partially of an elastic material and partially of a highly rigid fiber. Furthermore, the ear straps 46 and the chin straps 47 may be made of any other configuration that provides both elasticity and rigidity.

[0043] Furthermore, the "adjuster" in this embodiment may be any configuration that can fix the string portion 2b to the wearer's head by adjusting the length of one or both of the chin straps 47, 47. For example, instead of the chin strap buckle 48 in this embodiment, a cord stopper, a tape adjuster, a snap hook, a D-ring, an O-ring, etc. may be provided.

[0044] Next, a preparation procedure before use and a procedure for using the helmet 1A of this embodiment will be described.

[0045] First, the preparation procedure before use will be described.

[0046] A wearer using this helmet 1A first puts the helmet 1A on his / her head. In this state, the wearer slides the chin strap 47, with one end of the chin strap 47 inserted into the string guide portion 51 of the chin strap buckle 48. The wearer then adjusts the position of the chin strap buckle 48 so that the string portion 2b is long enough to be secured from the wearer's ears to the chin. In this way, when the wearer puts the helmet shell 1 of the helmet 1A on his / her head and puts the string portion 2b from the ears to the chin, the helmet shell 1 is secured to the wearer's head by the string portion 2b, thereby creating a state in advance.

[0047] In addition, if the wearer is someone who is putting the helmet 1A on their head with the assistance of another person, the assistant may place the helmet 1A on the wearer's head and adjust the position of the chin strap buckle 48, thereby preliminarily creating a state in which the helmet cap body 1 is fixed to the wearer's head.

[0048] Next, the procedure for use will be described.

[0049] As an example of use, consider a case where a wearer uses helmet 1A, the length of which has been adjusted in the preparation procedure, during a disaster or disaster evacuation.

[0050] First, the wearer puts the helmet 1A, with the engaging member 49 of the chin strap buckle 48 engaged with the engaged member 50, on his / her head with the forehead protection member 3 and the visor 4 of the helmet shell 1 facing forward. Then, with the top of his / her head in contact with the hammock 30, the wearer inserts his / her ears into the approximately triangular spaces (see Figure 11) formed by both ear straps 46, 46 of the helmet 1A.

[0051] In this state, when the wearer pulls the chin strap 47 downward (in the direction of arrow P in FIGS. 11, 12, and 13) with their fingers, a force pulling the ear straps 46, 46 connected to the chin strap 47 downward acts on them. As a result, tension acts on the ends of the front member 36 and the rear member 37 of the headband 31 (between one end of the front member 36 and the other end of the rear member 37, and between the other end of the front member 36 and one end of the rear member 37) in the directions indicated by arrows Q1 and Q2 in FIGS. 11 and 13. The tension in the ear straps 46 draws the front member 36 and the rear member 37 closer to each other. As a result, the front member 36 and the rear member 37 change from the spaced-apart state shown in FIGS. 11 and 12 to the close-together state shown in FIGS. 13 and 14. Specifically, the width of the wide right-side head gap 39 (and the left-side head gap 38 shown in FIG. 2) between the front member 36 and the rear member 37, as shown by the solid line in FIG. 11, is narrowed to the right-side head gap 39a (and the left-side head gap 38) as shown by the two-dot chain line in FIG. 11. Although not shown, the width of the left-side head gap 38 is also narrowed at this time. Then, the headband 31 is fastened and fixed in the circumferential direction of the head from the forehead of the wearer, passing through both sides, to the back of the head. Furthermore, the hammock 30 is pressed against the top of the wearer's head and fixed. In this state, the ear straps 46, 46 are pulled downward by the wearer's fingers and elastically deformed, becoming stretched downward as shown by the two-dot chain line in FIG. 11.

[0052] The wearer then places the pulled-down chin strap 47 around his chin. When the wearer then releases his fingers from the chin strap 47, an upward restoring force acts on the ear straps 46, 46 that have been stretched downward. As a result, the ear straps 46, 46 of the string portion 2b and the chin strap 47 are pulled upward.

[0053] In this way, the string 2b passes from one ear to the chin of the wearer's head, and is fixed from the other ear to the chin.

[0054] In addition, if the wearer is someone who is assisting another person in putting the helmet 1A on their head, the assistant may place the helmet 1A on the wearer's head, stretch the chin strap 47 downward, and then place it around the chin, thereby securing the strap portion 2b from the wearer's ears to the chin.

[0055] Even when the string portions 2b are fixed from the wearer's ears to the chin, the elastic force of the ear strings 46, 46 continues to act on the hammock 30 and the headband 31. This action presses the hammock 30 against the top of the wearer's head. This action also causes the right-side head gap 39 formed between the front member 36 and the rear member 37 of the headband 31 to remain narrow, as shown by the right-side head gap 39a indicated by the two-dot chain line in FIG. 11 . The headband 31 then remains fastened around the wearer's head. The interior material 2 is then fixed to the wearer's head, and the helmet shell 1 of the helmet 1A is also fixed to the wearer's head.

[0056] As a result, when the wearer puts the helmet body 1 on his / her head and places the string parts 2b from around the ears to around the chin, the helmet body 1 can be quickly and accurately fixed to the head. This allows the wearer to quickly and accurately wear the helmet 1A. Moreover, when wearing the helmet 1A, the helmet 1A can be fixed to the head without connecting the chin straps 47, 47 of the string parts 2b together or adjusting the length of the chin strap 47.

[0057] Furthermore, the wearer can freely adjust the length of the chin strap 47 by sliding the chin strap 47 inserted through the string hole 51 of the chin strap buckle 48 while the string 2b is still attached to the wearer's head. Adjusting the length of the chin strap 47 allows the wearer to freely adjust the tension of the string 2b attached to the wearer's head. By adjusting the tension of the string 2b, the wearer can freely adjust the width of the right head-side gap 39 and the left head-side gap 38, and the pressing force of the hammock 30 on the top of the head. This allows the wearer to easily adjust the fastening state of the helmet 1A while the helmet 1A remains on the head.

[0058] On the other hand, when removing the helmet 1A from the head, the wearer pulls the chin strap 47 downward with his / her fingers, elastically deforming the ear straps 46 downward, and removes the chin strap 47 of the string portion 2b from the wearer's chin and the ear straps 46 from the wearer's ears. This releases the tension applied to the entire string portion 2b.

[0059] As the tension on the string 2b is released, the front and rear members 36 and 37 move in directions that separate the ends of the front and rear members 36 and 37 due to their respective elasticity (i.e., in the directions indicated by arrows Q3 and Q4 in FIG. 15). The tension that draws the front and rear members 36 and 37 of the headband 31 closer together weakens, and the narrow right-side head gap 39a (see FIGS. 15 and 11) between the front and rear members 36 and 37 widens to a wider right-side head gap 39 (see FIG. 11). Although not shown in FIG. 11 and other figures, the left-side head gap 38 also widens at this time. Furthermore, the pressure that presses the hammock 30 against the top of the wearer's head also weakens.

[0060] The tension on the head by the strings 2b, the fastening force on the head by the headband 31, and the pressing force on the head by the hammock 30 are all weakened, allowing the wearer to remove the helmet 1A from the head.

[0061] It is also possible to release the engagement of the chin strap buckle 48 of the helmet 1A and remove the helmet 1A from the wearer's head.

[0062] Furthermore, if the wearer is one who is putting the helmet 1A on their head with the assistance of another person, the assistant may release the string portion 2b from the wearer's head to remove the helmet 1A.

[0063] The headband main body 32 is formed from a material that is resistant to stretching and loss of rigidity even with repeated or long-term use, so the helmet 1A can be firmly fixed to the head even with repeated or long-term use.

[0064] Furthermore, the length of the chin strap 47 can be adjusted in advance by sliding the chin strap 47 in the string guide portion 51 of the chin strap buckle 48. Therefore, the helmet 1A can be formed in advance, prior to use, with the string portion 2b fitted to the wearer's head, and further with the headband 31 and hammock 30 fitted to the wearer's head. Therefore, the wearer can easily put on and take off the helmet 1A when in use.

[0065] The wearer can quickly and accurately fasten the helmet 1A to his / her head not only in normal times but also in emergencies such as earthquakes, fires, and various conflicts that require immediate fastening.

[0066] Furthermore, even if the wearer is an infant, elderly person, or physically disabled person who needs assistance from a guardian or caregiver to put on helmet 1A, the guardian or caregiver can prepare helmet 1A to fit the wearer's head in advance, and then quickly and accurately fit helmet 1A onto the wearer's head. This enables people who need assistance to smoothly and quickly take action to protect themselves from disasters and evacuate.

[0067] Next, when a plurality of helmets 1A are stacked for storage or distribution, the lower ends of the front member 36 and the rear member 37 are placed on the flat portions formed on the upper surfaces of the front mounting protrusion 18 and the rear mounting protrusion 22 of the helmet shell 1 of the lower helmet 1A, respectively, as shown in Fig. 16. Similarly, although not shown in Fig. 16, the lower ends of the front member 36 and the rear member 37 are also placed on the upper surfaces of the front mounting protrusion 17 and the rear mounting protrusion 21, respectively.

[0068] By placing the lower ends of the front member 36 and rear member 37 of the upper helmet 1A on the flat shapes provided on the upper surfaces of the front mounting protrusions 17, 18 and rear mounting protrusions 21, 22 of the lower helmet 1A, the mounting positions of each helmet 1A are fixed when multiple helmets 1A are stacked, preventing the stacked helmets 1A from shifting position. That is, as shown in Figure 17, both ends of the front member 36, which are convex downward, are placed on the upper surface of the front mounting protrusion 18 (and the front mounting protrusion 17 not shown in Figure 17), which is inclined downward toward the front, and further, the lower part of the end of the approximately straight rear member 37 is placed in contact with the upper surface of the rear mounting protrusion 22 (and the rear mounting protrusion 21 not shown in Figure 17), which is formed on a substantially horizontal surface.As a result, a strong frictional force acts at the abutment position between the front mounting protrusions 17, 18 and the front member 36, and at the abutment position between the rear mounting protrusions 21, 22 and the rear member 37, and it is possible to prevent the loading position of the helmet 1A stacked on top of another helmet 1A from shifting in the front-to-back direction (left-to-right direction in Figures 16 and 17). This makes it less likely that a helmet 1A stacked on top of another helmet 1A will wobble or collapse, even if many helmets 1A are stacked on top of each other.

[0069] Furthermore, when the helmets 1A are stacked, the width of the right head side gap 39 and the left head side gap 38 is widened (see Figure 17), so the size in the stacking direction when stacked, as shown by arrow T in Figure 16, can be reduced, thereby reducing bulkiness.

[0070] When stacking helmets 1A, the engagement of chin strap buckle 48 can be released. This further reduces the size of the helmets 1A in the stacking direction when stacked, as indicated by arrow T in Figure 16, and also reduces bulkiness.

[0071] As described above, in this embodiment, the ear straps 46, which are at least a part of the strings 2b that constitute the interior material 2 and that fasten from at least around the ears to the chin, are made of an elastic material, so that when the ear straps 46 and chin strap 47 of the strings 2b are placed around the wearer's ears and around the chin with the helmet body 1 placed on the wearer's head, the strings 2b are immediately fastened from around the ears to the chin by elastic deformation of the ear straps 46 of the strings 2b. Also, by adjusting the length of the chin strap 47 with the chin strap buckle 48 and adjusting the length of the strings 2b in advance to a length that can be fastened around the wearer's head, in an emergency such as a disaster or evacuation, the strings 2b can be immediately fastened to the wearer's head without having to make fine adjustments or settings to the strings 2b and chin strap buckle 48. Furthermore, because the strings 2b are arranged to be stretched between the front member 36 and the rear member 37 of the headband 31 via the left head-side gap 38 and the right head-side gap 39, when the strings 2b are placed around the wearer's ears and around the chin, a tension is applied to the strings 2b that pulls them downward, and this tension draws the front member 36 and the rear member 37 closer to each other at the left head-side gap 38 and the right head-side gap 39, immediately securing the headband 31 to the wearer's head. Furthermore, the helmet body 1 is immediately secured to the wearer's head. Therefore, the interior material 2 and the helmet body 1 can be quickly and easily secured to the heads of a variety of wearers, including when the wearer puts on the helmet 1A themselves and when a guardian or caregiver puts the helmet 1A on another wearer, including an infant, an elderly person, or a physically disabled person. Furthermore, the interior material 2 can be quickly and easily fixed to the head of a variety of wearers of the helmet 1A not only in normal times but also in emergencies such as disasters. This allows the interior material 2 to be quickly and accurately fixed to the head during use without requiring delicate fingertip manipulation.

[0072] In this embodiment, the ear straps 46, 46 that make up the string portion 2b are made of an elastic material, so that when the ear straps 46 and chin strap 47 of the string portion 2b are fastened around the wearer's ears to the chin during use, the elastic deformation and tension of the ear straps 46 immediately fasten the string portion 2b around the wearer's ears to the chin, and the helmet body 1 is immediately fastened to the wearer's head. This allows the interior material 2 to be securely fastened to the head during use without the need for delicate finger manipulation.

[0073] In this embodiment, the ear straps 46 and chin strap 47 that make up the strap portion 2b are provided as a pair, and each chin strap 47, 47 is connected to the left ear strap 46 and the right ear strap 46, respectively. This allows the chin straps 47, 47 to be separated into left and right parts, allowing the helmet 1A to be stored or transported without increasing the bulk of the strap portion 2b. Furthermore, chin strap buckles 48 are provided at the ends of the left and right chin straps 47, 47, respectively, to connect the chin straps 47, 47 and adjust the lengths of the chin straps 47, 47. By adjusting the lengths of the chin straps 47, 47 with the chin strap buckles 48 and connecting the chin strap buckles 48, the pair of chin straps 47, 47 are connected and secured to the chin area of ​​the head, allowing the length of the chin straps 47, 47 to be freely adjusted to fit the wearer's head and worn on the head. Therefore, the interior material 2 can be fitted to the wearer's head regardless of differences in head size. If the length of the chin strap 47 is adjusted in advance using the chin strap buckle 48, the interior material 2 can be fitted to the wearer's head more quickly and easily, not only in normal times but also in emergencies such as disasters. Furthermore, the interior material 2 can be fitted to the heads of a variety of wearers, including when the wearer puts on the helmet 1A themselves and when a guardian or caregiver puts the helmet 1A on another wearer, including an infant, the elderly, or the physically disabled. This allows the interior material 2 to be fixed to the head more reliably during use, without the need for delicate finger manipulation.

[0074] In this embodiment, the hammock 30 for fastening the helmet shell 1 to the top of the head is pressed against the top of the head by the tension of the strings 2b and fixed, thereby fixing the interior material 2 to the top of the wearer's head. This allows the interior material 2 to be reliably fixed to the wearer's head, including the top of the head, without requiring delicate finger manipulation during use.

[0075] In this embodiment, a helmet 1A can be provided that can be quickly and accurately fixed to the head during use without requiring delicate finger manipulation.

[0076] In this embodiment, the headband main body 32 includes two "surrounding members," a front member 36 and a rear member 37, and the string 2b is arranged to be stretched between the front member 36 and the rear member 37 of the headband 31 via a left-head-side gap 38 and a right-head-side gap 39, which serve as "gaps." Alternatively, the "surrounding members" may be formed from a single continuous member with only one gap, and the string 2b may be stretched between the "surrounding members" via this gap. In this embodiment, the left-head-side gap 38 and the right-head-side gap 39 are formed at positions on both sides of the wearer's head, but this is not limiting. The "surrounding members" may be arranged at both sides of the wearer's head, and "gaps" may be formed at the front or rear of the head, and the string 2b may be stretched between the "surrounding members" via this "gap." Furthermore, the "surrounding member" may be formed of three or more members arranged at least around the wearer's head, or three or more "gap portions" may be formed, with the string portion 2b being hung on the "surrounding member" through these "gap portions."

[0077] Furthermore, in this embodiment, the helmet is configured with a helmet shell 1 formed into a shape that covers the head by combining multiple polygons, but this is not limited to this, and the same effect as this embodiment can also be obtained with a helmet having a helmet shell as a "hat main body" of other configurations.

[0078] Specifically, for example, the present invention can be applied to a folding helmet that has multiple plates formed from a material that maintains its shape in a flat state, and that can change shape (between when in use and when not in use) between a state in which these plates are approximately flat when folded (hereinafter referred to as the "flat state") and a state in which these plates are unfolded into a three-dimensional shape that can accommodate the head inside and be worn on the head (hereinafter referred to as the "unfolded state").

[0079] A folding helmet to which the present invention is applied can be provided, for example, by providing a hat body as a "hat main body" made of multiple plate materials connected by hinges and capable of being transformed between a flat state and an unfolded state, with an interior material 2 as a "hat interior material" similar to that of this embodiment or a configuration similar to that of the interior material 2, thereby providing a helmet that can be quickly and accurately fixed to the head in the same way as helmet 1A of this embodiment.

[0080] Furthermore, for example, a helmet body as a "hat main body" that has a plurality of circular or bowl-shaped plate materials and that can be folded or some plate materials are placed inside other plate materials to form a flattened state and assembled three-dimensionally into an unfolded state can be provided with an interior material 2 as a "hat interior material" similar to this embodiment or a configuration similar to the interior material 2, thereby providing a helmet that can be quickly and accurately fixed to the head in the same way as helmet 1A of this embodiment.

[0081] In addition, a helmet having an approximately hemispherical or similar shape, serving as a "hat main body" for various uses such as disaster prevention, construction, sports, mountain climbing, riding, police, firefighting, and combat, can be provided with an interior material 2 or a similar configuration as the interior material 2 as a "hat interior material" similar to that of this embodiment, thereby providing a helmet that can be quickly and accurately fixed to the head in the same way as helmet 1A of this embodiment.

[0082] In addition, in this embodiment, various types of hats other than helmets, such as sports caps, work caps, hats, farm work hats, straw hats, and other types of hats serving as the "hat main body," can be provided with interior material 2 as the "hat interior material" similar to that of this embodiment, or a configuration similar to that of interior material 2, thereby providing a hat that can quickly and accurately protect the head from direct sunlight and dust, similar to helmet 1A of this embodiment.

[0083] The above-described embodiments are merely examples of the present invention, and it goes without saying that the present invention is not limited to the above-described embodiments. [Explanation of symbols]
