[0009] The following exemplary embodiments will be described in detail with reference to the drawings.
[0010] Figure 1 is a plan view of the head cooler 100 in a non-use state. Figure 2 is a bottom view of the head cooler 100 in a non-use state. Figure 3 is a cross-sectional view of the head cooler 100 along line III-III in Figure 1. Figure 4 is a schematic diagram showing the head cooler 100 in use.
[0011] The head cooling device 100 is used to cool the head 8 of a person. The head cooling device 100 is installed inside a protective helmet 90 that is worn on the head 8 of a person. Specifically, the head cooling device 100 cools the forehead 81, back of the head 82, top of the head 83, and sides of the head 84 of the person. The protective helmet 90 is, for example, a work helmet, motorcycle helmet, bicycle helmet, or climbing helmet.
[0012] The head cooler 100 comprises a first cooler body 1a and a second cooler body 1b for cooling the head 8, and a connector 7 for detachably connecting the second cooler body 1b to the first cooler body 1a. When the head cooler 100 is in use, the first cooler body 1a is positioned above and the second cooler body 1b is positioned below. The first cooler body 1a is placed on top of the second cooler body 1b. In other words, the second cooler body 1b is positioned on the head 8 side, and the first cooler body 1a is positioned on the opposite side of the head 8. As a result, the second cooler body 1b is in contact with the head 8, while the first cooler body 1a is not in contact with the head 8.
[0013] Hereinafter, each direction in the head cooling device 100 will be described as each direction in the state in which the head cooling device 100 is in use. For example, the upward direction in the head cooling device 100 coincides with the upward direction in the state in which the head cooling device 100 is in use.
[0014] The first cooling tool body 1a has flexibility. The first cooling tool body 1a is formed in a plate shape. In this example, the shape of the first cooling tool body 1a is circular with a plurality of cuts 6a formed therein, which will be described later. The first cooling tool body 1a is deformable between a plate-shaped first state and a curved second state. The curved shape of the second state can be cup-shaped, bowl-shaped, bell-shaped or spherical-crown-shaped. The first state is the state when the head cooling tool 100 is not in use, and the second state is the state when the head cooling tool 100 is in use. In the following description, unless otherwise specified, the first cooling tool body 1a in the first state will be described. In this example, the first cooling tool body 1a is formed in an overall circular shape. The first cooling tool body 1a has an outer peripheral edge 19a. The first cooling tool body 1a has a cold insulating agent 2a and an outer package 3a that houses the cold insulating agent 2a.
[0015] The cold insulating agent 2a is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The cold insulating agent 2a contains, for example, aliphatic hydrocarbons. The aliphatic hydrocarbons are, for example, paraffin or aliphatic saturated hydrocarbons. The cold insulating agent 2a may contain at least one of tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ) and octadecane (C 18 H 38 ). The cold insulating agent 2a may contain only one or only two of tetradecane, hexadecane and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, the cold insulating agent 2a may further contain a super absorbent polymer (SAP), water, aroma, graphite, organic substances or minerals, etc. The melting point of the cold insulating agent 2a is, for example, room temperature. The melting point of the cold insulating agent 2a is preferably 5°C or higher and 35°C or lower, and more preferably 15°C or higher and 35°C or lower. The cold insulating agent 2a absorbs the heat of the human body as sensible heat when in the solid and liquid phases. When the cold insulating agent 2a changes from the solid phase to the liquid phase, it absorbs the heat of the human body as latent heat, specifically, heat of fusion.
[0016] The outer package 3a is flexible. The outer package 3a is formed from one or a mixture of a plurality of resins such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).
[0017] The outer package 3a includes a plurality of accommodating portions 32a that individually accommodate the cold insulating agent 2a. The outer package 3a further includes a peripheral portion 31a that forms the outer peripheral edge 19a of the first cooling tool main body 1a and a partitioning portion 33a that partitions the internal space into the plurality of accommodating portions 32a. In FIG. 1, for the sake of convenience of explanation, dots are attached to the plurality of accommodating portions 32a. The same applies to FIG. 2 described later.
[0018] Each of the plurality of accommodating portions 32a is sealed. That is, the cold insulating agent 2a is individually accommodated for each accommodating portion 32a. In this example, each of the plurality of accommodating portions 32a has a substantially trapezoidal or substantially semi-circular planar shape. At substantially the center of the first cooling tool main body 1a, two substantially semi-circular accommodating portions 32a are arranged so as to be substantially circular. A plurality of substantially trapezoidal accommodating portions 32a are arranged radially around the two substantially semi-circular accommodating portions 32a. Specifically, three substantially trapezoidal accommodating portions 32a are arranged side by side in the radial direction to form a group of substantially trapezoidal accommodating portions 32a, and six groups of substantially trapezoidal accommodating portions 32a are arranged radially around the substantially semi-circular accommodating portions 32a.
[0019] The plurality of accommodating portions 32a are arranged corresponding to the forehead 81, occipital region 82, vertex 83, and temporal region 84 of the human body when the head cooling tool 100 is in use. Specifically, the substantially semi-circular accommodating portion 32a is arranged corresponding to the vertex 83 of the human body when the head cooling tool 100 is in use. The substantially trapezoidal accommodating portion 32a is arranged corresponding to the forehead 81, occipital region 82, and temporal region 84 of the human body when the head cooling tool 100 is in use.
[0020] The outer packaging 3a has a plurality of notches 6a formed on its outer peripheral edge 19a. The notches 6a extend radially inward from the outer peripheral edge 19a to the first cooler body 1a. The notches 6a have a width that increases from the inside of the first cooler body 1a toward the outer peripheral edge 19a in the direction in which the notches 6a extend. The notches 6a are generally formed in a wedge shape. Six notches 6a are formed at equal intervals along the outer peripheral edge 19a.
[0021] The outer packaging 3a includes a first part 35a corresponding to the top of the human head 83, and a second part 36a corresponding to the forehead 81, back of the head 82, and sides of the human head 84. The second part 36a includes a plurality of circumferentially divided segments 37a.
[0022] Specifically, the first part 35a is formed in a circular shape. The second part 36a is formed in a roughly annular shape surrounding the first part 35a. The outer edge of the first part 35a and the inner edge of the second part 36a coincide. The first part 35a and the second part 36a are continuous.
[0023] The notch 6a is formed in the second portion 36a. The notch 6a extends from the outer edge 19a to a predetermined position between the outer edge 19a and the outer edge of the first portion 35a. In this example, the notch 6a extends from the outer edge 19a to the outer edge of the first portion 35a. The second portion 36a is divided circumferentially into six parts by the notch 6a, forming six divided parts 37a. The six divided parts 37a extend radially.
[0024] The first part 35a has a roughly semicircular storage section 32a, and the divided body 37a has a roughly trapezoidal storage section 32a. More specifically, the inner of the three roughly trapezoidal storage sections 32a arranged radially spans both the first part 35a and the divided body 37a.
[0025] The outer packaging 3a is formed by overlapping and joining two sheets together. Specifically, the outer packaging 3a is formed by joining together a first sheet 41a and a second sheet 42a that are opposite each other in the thickness direction. The first sheet 41a is positioned above, and the second sheet 42a is positioned below.
[0026] The first sheet 41a has multiple recesses 411a formed on the side opposite to the second sheet 42a. The second sheet 42a is flat. The recesses 411a are closed by the second sheet 42a. The first sheet 41a and the second sheet 42a are joined to each other such that the recesses 411a are sealed by the second sheet 42a.
[0027] Specifically, the portion of the first sheet 41a excluding the recesses 411a, i.e., the outer edge of the first sheet 41a and the portion between adjacent recesses 411a, is joined to the second sheet 42a. The joining of the first sheet 41a and the second sheet 42a is achieved, for example, by heat welding. In Figure 3, the boundary of the joined portion in the outer packaging 3a is shown with a solid line, but in reality, the boundary of the joined portion does not need to be clearly visible.
[0028] The peripheral edge 31a is formed by joining the peripheral edge of the first sheet 41a and the peripheral edge of the second sheet 42a. The accommodating portion 32a is formed by the recess 411a and the second sheet 42a. The partition portion 33a is formed by joining the portion of the first sheet 41a between adjacent recesses 411a and the second sheet 42a.
[0029] The second cooling device body 1b includes a cooling agent 2b and an outer pack 3b that contains the cooling agent 2b. The components designated with the symbol "b" in the second cooling device body 1b correspond to the components designated with the symbol "a" in the first cooling device body 1a. Therefore, unless otherwise specified, the components of the second cooling device body 1b are the same as those of the first cooling device body 1a.
[0030] The second cooling device body 1b has the same shape as the first cooling device body 1a in plan view. The second cooling device body 1b is formed in a plate shape. The second cooling device body 1b is flexible. The second cooling device body 1b can be deformed between a first plate shape and a second curved shape. The first state is the state when the head cooling device 100 is not in use, and the second state is the state when the head cooling device 100 is in use.
[0031] The cooling agent 2b is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The cooling agent 2b contains, for example, an aliphatic hydrocarbon. The melting point of the cooling agent 2b is, for example, room temperature. Preferably, the melting point of the cooling agent 2b is 5°C or higher and 35°C or lower, and more preferably 15°C or higher and 35°C or lower. When the cooling agent 2b is in the solid and liquid phases, it absorbs the heat of the human body as sensible heat. When the cooling agent 2b changes from the solid phase to the liquid phase, it absorbs the heat of the human body as latent heat, more specifically as heat of fusion.
[0032] The melting point of the coolant 2b of the second cooling device body 1b (hereinafter also referred to as "second coolant 2b") is different from the melting point of the coolant 2a of the first cooling device body 1a (hereinafter also referred to as "first coolant 2a"). Specifically, the melting point of the second coolant 2b is lower than that of the first coolant 2a. For example, the melting point of the second coolant 2b is 18°C, and the melting point of the first coolant 2a is 28°C. To make the melting point of the second coolant 2b lower than that of the first coolant 2a, for example, an aliphatic hydrocarbon having a lower melting point than the aliphatic hydrocarbon of the first coolant 2a can be used as the aliphatic hydrocarbon of the second coolant 2b. The means of making the melting point of the second coolant 2b lower than that of the first coolant 2a are not limited. For example, even when using aliphatic hydrocarbons with the same melting point, the melting point of the second coolant 2b can be made lower than that of the first coolant 2a by making the proportion of aliphatic hydrocarbons in the first coolant 2a different from the proportion of aliphatic hydrocarbons in the second coolant 2b.
[0033] The outer packaging 3b is flexible. The outer packaging 3b is formed from one or more resins, such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).
[0034] The outer pack 3b includes a plurality of storage compartments 32b for individually accommodating the coolant packs 2b. The outer pack 3b further includes a peripheral portion 31b that forms the outer peripheral edge 19b of the second cooling device body 1b, and a partition portion 33b that divides the internal space into a plurality of storage compartments 32b.
[0035] Each of the multiple storage compartments 32b is sealed. That is, the cooling packs 2b are individually housed in each storage compartment 32b. In this example, each of the multiple storage compartments 32b has a planar shape that is approximately trapezoidal or semicircular.
[0036] The multiple housing sections 32b contact the forehead 81, back of the head 82, crown 83, and sides of the head 84 of the human body when the head cooling device 100 is in use, thereby cooling the head 8. Specifically, the roughly semicircular housing section 32b is positioned to correspond to the crown 83 of the human body when the head cooling device 100 is in use. The roughly trapezoidal housing section 32b is positioned to correspond to the forehead 81, back of the head 82, and sides of the human body when the head cooling device 100 is in use.
[0037] The thickness t2 of the housing portion 32b of the second cooler body 1b is smaller than the thickness t1 of the housing portion 32a of the first cooler body 1a. The thickness t2 of the housing portion 32b refers to the maximum thickness of the housing portion 32b. The thickness t1 of the housing portion 32a refers to the maximum thickness of the housing portion 32a.
[0038] The outer packaging 3b has a plurality of notches 6b formed on its outer peripheral edge 19b. The notches 6b extend radially inward from the outer peripheral edge 19b to the second cooler body 1b. The notches 6b have a width that increases from the inside of the second cooler body 1b towards the outer peripheral edge 19b in the direction in which the notches 6b extend.
[0039] The outer packaging 3b includes a first part 35b corresponding to the top of the human head 83 and a second part 36b corresponding to the forehead 81, back of the head 82, and sides of the human head 84. The second part 36b includes a plurality of circumferentially divided segments 37b.
[0040] Specifically, the first part 35b cools the top of the head 83 of the human body. The first part 35b is formed in a circular shape. The second part 36b cools the forehead 81, back of the head 82, and sides of the human body 84. The second part 36b is formed in a roughly ring shape surrounding the first part 35b.
[0041] The notch 6b is formed in the second part 36b. The second part 36b is divided circumferentially into six parts by the notch 6b, forming six divided bodies 37b. The six divided bodies 37b extend radially.
[0042] The first part 35b has a roughly semicircular storage section 32b, and the divided body 37b has a roughly trapezoidal storage section 32b. More specifically, the inner of the three roughly trapezoidal storage sections 32b arranged radially spans both the first part 35b and the divided body 37b.
[0043] The first portion 35b of the second cooler body 1b overlaps with the first portion 35a of the first cooler body 1a. The second portion 36b of the second cooler body 1b overlaps with the second portion 36a of the first cooler body 1a. Specifically, each segment 37b of the second cooler body 1b overlaps with each segment 37a of the first cooler body 1a.
[0044] The outer packaging 3b is formed by overlapping and joining two sheets together. Specifically, the outer packaging 3b is formed by joining a first sheet 41b and a second sheet 42b that are opposite each other in the thickness direction. The first sheet 41b is positioned above, and the second sheet 42b is positioned below.
[0045] The first sheet 41b has multiple recesses 411b formed in the opposite direction from the second sheet 42b. The second sheet 42b has multiple recesses 421b formed in the opposite direction from the first sheet 41b. The recesses 411b and 421b are opposite each other. The recesses 411b and 421b are closed to each other. The first sheet 41b and the second sheet 42b are joined to each other such that the recesses 411b and 421b are sealed.
[0046] Specifically, the portion of the first sheet 41b excluding the recesses 411b, i.e., the portion of the first sheet 41b between the outer periphery and adjacent recesses 411b, is joined to the portion of the second sheet 42b excluding the recesses 421b, i.e., the portion of the second sheet 42b between the outer periphery and adjacent recesses 421b. More specifically, the outer periphery of the first sheet 41b and the outer periphery of the second sheet 42b are joined, and the portion of the first sheet 41b between adjacent recesses 411b and the portion of the second sheet 42b between adjacent recesses 421b are joined. The joining of the first sheet 41b and the second sheet 42b is achieved, for example, by heat welding.
[0047] The peripheral edge 31b is formed by joining the peripheral edge of the first sheet 41b and the peripheral edge of the second sheet 42b. The accommodating portion 32b is formed by recesses 411b and 421b. The partition portion 33b is formed by joining the portion of the first sheet 41b between adjacent recesses 411b and the portion of the second sheet 42b between adjacent recesses 421b.
[0048] The connector 7 is positioned between the first cooler body 1a and the second cooler body 1b. Specifically, the connector 7 is positioned between the opposing surface of the first cooler body 1a that faces the second cooler body 1b and the opposing surface of the second cooler body 1b that faces the first cooler body 1a.
[0049] The connector 7 includes a first connecting portion 71 and a second connecting portion 72. The first connecting portion 71 is provided on the first cooler body 1a. The second connecting portion 72 is provided on the second cooler body 1b. The second connecting portion 72 is detachably connected to the first connecting portion 71. In Figure 3, the first connecting portion 71 and the second connecting portion 72 are depicted as thicker than they actually are to make them easier to distinguish.
[0050] The first connecting portion 71 and the second connecting portion 72 are magnets. The magnets are, for example, ferrite magnets, neodymium magnets, etc. The first connecting portion 71 and the second connecting portion 72 are round, but they may also be polygonal, and the shape of the first connecting portion 71 and the second connecting portion 72 is not limited.
[0051] The first connecting portion 71 is provided on the opposing surface of the first cooler body 1a facing the second cooler body 1b. Specifically, the first connecting portion 71 is covered by a cover sheet 43a and sandwiched between the second sheet 42a and the cover sheet 43a of the first cooler body 1a. The cover sheet 43a is joined to the second sheet 42a. The joining of the cover sheet 43a and the second sheet 42a is achieved, for example, by heat welding.
[0052] The second connecting portion 72 is provided on the opposing surface of the second cooler body 1b that faces the first cooler body 1a. Specifically, the second connecting portion 72 is covered by a cover sheet 43b and sandwiched between the first sheet 41b and the cover sheet 43b of the second cooler body 1b. The cover sheet 43b is joined to the first sheet 41b. The joining of the cover sheet 43b and the first sheet 41b is achieved, for example, by heat welding.
[0053] Figure 5 is a bottom view of the first cooler body 1a, showing the opposing surface of the first cooler body 1a facing the second cooler body 1b. The first connecting portion 71 is located in each of the multiple divided bodies 37a. Specifically, the first connecting portion 71 is located in each of the multiple housing portions 32a located in the divided bodies 37a.
[0054] Multiple first connecting portions 71 are arranged radially from the center of the first cooler body 1a. More specifically, three first connecting portions 71 are arranged radially to form a group of first connecting portions 71, and six groups of first connecting portions 71 are arranged radially from the center of the first cooler body 1a.
[0055] More specifically, the multiple first connecting parts 71 are arranged radially from the center of the first cooler body 1a. The magnetic poles of adjacent first connecting parts 71 in the radial direction are different. In other words, when viewed from the bottom surface of the first cooler body 1a, the first connecting parts 71 with north poles and the first connecting parts 71 with south poles are arranged alternately in the radial direction. Note that the magnetic poles on the front and back sides of the first connecting parts 71 are different.
[0056] Furthermore, the multiple first connecting portions 71 are arranged in a line in the circumferential direction of the first cooler body 1a. The magnetic poles of adjacent first connecting portions 71 in the circumferential direction are different. In other words, when viewed from the bottom surface of the first cooler body 1a, the first connecting portions 71 with north poles and the first connecting portions 71 with south poles are arranged alternately in the circumferential direction.
[0057] Figure 6 is a plan view of the second cooler body 1b, showing the opposing surface of the second cooler body 1b facing the first cooler body 1a. The second connecting portion 72 is located in each of the multiple divided bodies 37b. Specifically, the second connecting portion 72 is located in each of the multiple housing portions 32b located in the divided body 37b.
[0058] Multiple second connecting portions 72 are arranged radially from the center of the second cooler body 1b. Specifically, three second connecting portions 72 are arranged radially to form a group of second connecting portions 72, and six groups of second connecting portions 72 are arranged radially from the center of the second cooler body 1b.
[0059] More specifically, the multiple second connecting portions 72 are arranged radially from the center of the second cooler body 1b. The magnetic poles of adjacent second connecting portions 72 in the radial direction are different. In other words, when viewed from the plane of the second cooler body 1b, north-pole second connecting portions 72 and south-pole second connecting portions 72 are arranged alternately in the radial direction. Note that the magnetic poles on the front and back sides of the second connecting portions 72 are different.
[0060] Furthermore, multiple second connecting portions 72 are arranged in a line in the circumferential direction of the second cooler body 1b. The magnetic poles of adjacent second connecting portions 72 in the circumferential direction are different. In other words, when viewed from the bottom surface of the second cooler body 1b, north-pole second connecting portions 72 and south-pole second connecting portions 72 are arranged alternately in the circumferential direction.
[0061] In the first and second connecting sections 72 that are connected to each other, the magnetic poles of the first connecting section 71 and the magnetic poles of the second connecting section 72 are different. That is, the north pole of the first connecting section 71 corresponds to the south pole of the second connecting section 72, and the south pole of the first connecting section 71 corresponds to the north pole of the second connecting section 72.
[0062] Figure 7 is a side view of the protective helmet 90 showing a partial cross-section of the protective helmet 90. The protective helmet 90 has a helmet body 91 and a fitting body 92 attached to the inside of the helmet body 91. The protective helmet 90 further has an impact absorbing member 93 and a chin strap 94. Note that the impact absorbing member 93 and the chin strap 94 may be omitted.
[0063] The helmet shell 91 is the outer shell of the protective helmet 90. The helmet shell 91 covers the head 8 and can withstand external impacts. The material of the helmet shell 91 is, for example, a resin such as ABS, PC, PE, or FRP.
[0064] The impact-absorbing member 93 is fixed to the inner surface of the helmet shell 91. The impact-absorbing member 93 absorbs external impacts. The material of the impact-absorbing member 93 is, for example, expanded polystyrene.
[0065] The mounting body 92 is fixed to the inner surface of the helmet shell 91. The mounting body 92 holds the protective helmet 90 on the head 8, improving the contact of the protective helmet 90 with the head 8 and mitigating impact. The material of the mounting body 92 is, for example, resin or fiber.
[0066] The wearer 92 includes a headband 92a, a loop cord 92b, and a hammock 92c. The headband 92a is wrapped around the head 8. The headband 92a can be adjusted to fit the size of the head 8. The loop cord 92b is positioned opposite the top of the head 83. The hammock 92c is stretched over the headband 92a and the loop cord 92b. The hammock 92c extends in the vertical direction. The wearer 92 includes multiple hammocks 92c. The multiple hammocks 92c are arranged at intervals around the head 8.
[0067] The chin strap 94 is attached to the headband 92a of the helmet body 92. The chin strap 94 prevents the protective helmet 90 from falling off the head 8. The material of the chin strap 94 is, for example, resin or fiber.
[0068] The protective helmet 90 has a gap between the helmet shell 91 and the attachment body 92. Specifically, the gap exists between the impact-absorbing member 93 and the attachment body 92. More specifically, the gap exists between the impact-absorbing member 93 and the loop strap 92b and hammock 92c of the attachment body 92.
[0069] Figure 8 is a cross-sectional view of a protective helmet 90 with a head cooling device 100 installed. The first cooling device body 1a is positioned between the helmet shell 91 and the body 92. Specifically, the first cooling device body 1a is inserted into the gap between the helmet shell 91 and the body 92. More specifically, the first cooling device body 1a is inserted into the gap between the impact absorbing member 93 and the loop strap 92b and hammock 92c of the body 92.
[0070] The second cooling device body 1b is superimposed on the first cooling device body 1a so as to sandwich the mounting body 92 together with the first cooling device body 1a, and is connected to the first cooling device body 1a by a connecting device 7.
[0071] Specifically, the first cooling device body 1a and the second cooling device body 1b hold at least the loop cord 92b of the loop cord 92b and the hammock 92c. More specifically, the first part 35a of the first cooling device body 1a and the first part 35b of the second cooling device body 1b hold the loop cord 92b. Each segment 37a of the first cooling device body 1a and each segment 37b of the second cooling device body 1b hold the hammock 92c, as will be described later.
[0072] Furthermore, each segment 37a of the first cooling device body 1a and each segment 37b of the second cooling device body 1b are connected by a connector 7 in the space between adjacent hammocks 92c around the head 8. More specifically, each housing section 32a of the segment 37a of the first cooling device body 1a and each housing section 32b of the segment 37b of the second cooling device body 1b are connected to each other by a connector 7.
[0073] Next, a method for installing the head cooling device 100 on the protective helmet 90 will be described. Figure 9 is a bottom view of the protective helmet 90 with the first cooling device body 1a installed. Figure 10 is a bottom view of the protective helmet 90 with the first cooling device body 1a and the second cooling device body 1b installed.
[0074] As shown in Figure 9, the first cooling device body 1a is folded and inserted into the gap between the helmet shell 91 (in this example, the impact absorbing member 93) and the mounting body 92 from the space between adjacent hammocks 92c in the circumferential direction, thereby positioning the first cooling device body 1a in the gap between the helmet shell 91 and the mounting body 92.
[0075] At this time, when viewed from the bottom surface of the protective helmet 90, the first portion 35a of the first cooling device body 1a is positioned to overlap the loop strap 92b. Also, the notch 6a of the first cooling device body 1a is positioned to overlap the hammock 92c, and the circumferential side edges of the divided body 37a of the first cooling device body 1a are positioned to overlap the hammock 92c. Furthermore, the first connecting portion 71 is positioned to overlap the space between adjacent hammocks 92c in the circumferential direction.
[0076] Subsequently, as shown in Figure 10, the second connecting portion 72 is positioned toward the first connecting portion 71, and the second cooling device body 1b is placed on top of the first cooling device body 1a so as to sandwich the mounting body 92 between the first cooling device body 1a and the second cooling device body 1b. The second connecting portion 72 is then connected to the first connecting portion 71, and the second cooling device body 1b is connected to the first cooling device body 1a.
[0077] At this time, when viewed from the bottom surface of the protective helmet 90, the first portion 35b of the second cooling device body 1b is positioned to overlap the loop strap 92b. Also, the notch 6b of the second cooling device body 1b is positioned to overlap the hammock 92c, and the circumferential side edge of the divided body 37b of the second cooling device body 1b is positioned to overlap the hammock 92c. The second connecting portion 72 is positioned to overlap the space between adjacent hammocks 92c in the circumferential direction.
[0078] In other words, when viewed from the bottom surface of the protective helmet 90, the first portion 35b of the second cooling device body 1b overlaps with the first portion 35a of the first cooling device body 1a. Also, each segment 37b of the second cooling device body 1b overlaps with each segment 37a of the first cooling device body 1a. Furthermore, the second connecting portion 72 overlaps with the first connecting portion 71.
[0079] As a result, the first part 35a of the first cooling device body 1a and the first part 35b of the second cooling device body 1b hold the loop string 92b, and each segment 37a of the first cooling device body 1a and each segment 37b of the second cooling device body 1b hold the hammock 92c. The second connecting part 72 is connected to the first connecting part 71. Therefore, the head cooling device 100 can be attached to the wearer 92.
[0080] According to the aforementioned head cooling device 100, the first cooling device body 1a and the second cooling device body 1b are stacked on top of each other so as to sandwich the wearer 92, and the connecting device 7 connects the first cooling device body 1a and the second cooling device body 1b. As a result, the head cooling device 100 is attached to the wearer 92 while sandwiching it. Therefore, the head cooling device 100 can be stably installed inside the protective helmet 90.
[0081] Furthermore, since the first cooling device body 1a is positioned between the helmet shell 91 and the wearer 92, the first cooling device body 1a can cool the air present in the gap between the helmet shell 91 and the wearer 92. As a result, the first cooling device body 1a can indirectly cool the head 8.
[0082] Furthermore, since the second cooling device body 1b is positioned on the opposite side of the body 92 from the first cooling device body 1a, the second cooling device body 1b can come into contact with the head 8. As a result, the second cooling device body 1b can directly cool the head 8.
[0083] Furthermore, since the first cooling device body 1a is positioned between the helmet shell 91 and the wearer 92, the first cooling device body 1a can be placed in the dead space between the helmet shell 91 and the wearer 92, and the cooling effect can be improved without substantially increasing the thickness of the head cooling device 100 when the head cooling device 100 is installed on the protective helmet 90.
[0084] Furthermore, since the connector 7 is positioned between the first cooling device body 1a and the second cooling device body 1b, the connector 7 is less likely to be exposed to the outside. As a result, when the head cooling device 100 is installed on a protective helmet 90, hair is less likely to get tangled in the connector 7.
[0085] Furthermore, since the connector 7 includes a first connecting portion 71 provided on the first cooler body 1a and a second connecting portion 72 provided on the second cooler body 1b, the connector 7 can be integrally held by the first cooler body 1a and the second cooler body 1b. As a result, when separating the first cooler body 1a and the second cooler body 1b from each other, the connector 7 does not separate from the first cooler body 1a and the second cooler body 1b, making management easier.
[0086] Furthermore, since the first connecting portion 71 and the second connecting portion 72 are magnets, they are attracted to each other by magnetic force, making it easy to attach and detach the first cooling device body 1a and the second cooling device body 1b.
[0087] Specifically, the first cooling device body 1a and the second cooling device body 1b can be connected without having to press them in opposite directions. More specifically, since the first cooling device body 1a is positioned between the helmet shell 91 and the wearing body 92, it is difficult to press the first cooling device body 1a toward the second cooling device body 1b. However, since the first connecting part 71 and the second connecting part 72 are magnets, the first cooling device body 1a and the second cooling device body 1b can be connected simply by bringing the second cooling device body 1b closer to the first cooling device body 1a, without having to press the first cooling device body 1a toward the second cooling device body 1b.
[0088] Furthermore, since the first connecting portion 71 and the second connecting portion 72 are magnets, when the head cooling device 100 is installed on the protective helmet 90, hair is less likely to get tangled in the first connecting portion 71 and the second connecting portion 72 compared to when the first connecting portion 71 and the second connecting portion 72 are hook-and-loop fasteners.
[0089] Furthermore, since the first connecting portion 71 and the second connecting portion 72 are magnets, when the head cooling device 100 is installed on the protective helmet 90, the magnetic field of the magnets promotes blood flow in the head 8. Specifically, the magnetic field of the magnets acts on the cells, nervous system, blood flow system, etc. of the head 8, and can regulate the biomagnetic field and bioelectric current.
[0090] Furthermore, since the first connecting portion 71 is positioned on each of the multiple divided parts 37a of the second portion 36a of the first cooling device body 1a, all the divided parts 37a of the second portion 36a of the first cooling device body 1a can be connected to the second cooling device body 1b, and the first cooling device body 1a and the second cooling device body 1b can be firmly connected. Accordingly, the head cooling device 100 can be stably installed inside the protective helmet 90.
[0091] Furthermore, since the first connecting portion 71 is positioned corresponding to each of the multiple housing portions 32a arranged on the divided body 37a, all of the housing portions 32a of the divided body 37a of the first cooling device body 1a can be connected to the second cooling device body 1b, and the first cooling device body 1a and the second cooling device body 1b can be firmly connected. Accordingly, the head cooling device 100 can be stably installed inside the protective helmet 90.
[0092] Furthermore, since the second connecting portion 72 is positioned on each of the multiple divided parts 37b of the second portion 36b of the second cooling device body 1b, all of the divided parts 37b of the second portion 36b of the second cooling device body 1b can be connected to the first cooling device body 1a, and the first cooling device body 1a and the second cooling device body 1b can be firmly connected. Therefore, the head cooling device 100 can be stably installed inside the protective helmet 90.
[0093] Furthermore, since the second connecting portion 72 is positioned corresponding to each of the multiple housing portions 32b arranged in the divided body 37b, all of the housing portions 32b of the divided body 37b of the second cooling device body 1b can be connected to the first cooling device body 1a, and the first cooling device body 1a and the second cooling device body 1b can be firmly connected. Therefore, the head cooling device 100 can be stably installed inside the protective helmet 90.
[0094] Furthermore, the magnetic poles of adjacent second connecting parts 72 in the radial direction (radial direction) of the second cooling device body 1b are different. As a result, the magnetic forces of adjacent second connecting parts 72 in the radial direction attract each other, allowing the magnetic force to extend over a wide area. In other words, since the second cooling device body 1b is in contact with the head 8, the magnetic force of the second connecting parts 72 extends over a wide area, further promoting blood flow to the head 8. Specifically, the magnetic force of the second connecting parts 72 is emitted from the head 8 side of the second cooling device body 1b, allowing the magnetic force to extend to the head 8. For example, the strength of one magnet is 2000 gauss, which further promotes blood flow to the head 8.
[0095] Furthermore, the magnetic poles of adjacent second connecting portions 72 in the circumferential direction of the second cooling device body 1b are different. As a result, the magnetic forces of adjacent second connecting portions 72 in the circumferential direction attract each other, allowing the magnetic force to extend over a wide area. In other words, since the second cooling device body 1b is in contact with the head 8, the magnetic force of the second connecting portions 72 extends over a wide area, further promoting blood flow to the head 8.
[0096] Furthermore, the thickness t2 of the housing section 32b of the second cooling device body 1b is smaller than the thickness t1 of the housing section 32a of the first cooling device body 1a. This reduces the thickness t2 of the housing section 32b of the second cooling device body 1b, making the head cooling device 100 effectively thinner when installed in the protective helmet 90. On the other hand, increasing the thickness t1 of the housing section 32a of the first cooling device body 1a increases the volume of the housing section 32a of the first cooling device body 1a, thereby increasing the volume of the cooling agent 2a stored in the housing section 32a. Consequently, the cooling effect of the air present in the gap between the helmet shell 91 and the wearer 92 can be improved. In this case, since the first cooling device body 1a is placed in the dead space between the helmet shell 91 and the wearer 92, increasing the thickness t1 of the housing section 32a of the first cooling device body 1a does not increase the effective thickness of the head cooling device 100 when installed in the protective helmet 90. In this way, the effective thickness of the head cooling device 100 when in use can be reduced while improving the cooling performance of the head cooling device 100.
[0097] Furthermore, since the melting point of the coolant 2a in the first cooler body 1a is different from the melting point of the coolant 2b in the second cooler body 1b, the first cooler body 1a and the second cooler body 1b can be adapted to the desired application.
[0098] More specifically, since the melting point of the coolant 2b in the second cooler body 1b is lower than the melting point of the coolant 2a in the first cooler body 1a, the cooler can be used with the solid-phase coolant 2a of the first cooler body 1a and the liquid-phase coolant 2b of the second cooler body 1b coexisting.
[0099] In this case, the presence of the liquid phase of the cooling agent 2b enhances the cushioning properties of the second cooling device body 1b. In other words, since the second cooling device body 1b is in contact with the head 8, the highly cushioned liquid phase cooling agent 2b improves the comfort of the head cooling device 100 during use.
[0100] On the other hand, when the coolant 2b is in the liquid phase and the coolant 2a is in the solid phase, the first cooling device body 1a is placed between the helmet shell 91 and the body 92, so the air present in the gap between the helmet shell 91 and the body 92 can be quickly cooled using the solid-phase coolant 2a, which has high thermal conductivity.
[0101] In this way, by having a solid-phase coolant 2a with high cooling performance and a liquid-phase coolant 2b with excellent cushioning properties coexist, it is possible to achieve both cooling performance and cushioning.
[0102] Alternatively, the melting point of the coolant 2b in the second cooler body 1b may be higher than the melting point of the coolant 2a in the first cooler body 1a. In other words, the cooler can be used with the liquid-phase coolant 2a in the first cooler body 1a and the solid-phase coolant 2b in the second cooler body 1b coexisting.
[0103] In this case, the liquid phase of the cooling agent 2a improves the flexibility of the first cooling device body 1a, making it easier to fold the first cooling device body 1a and insert it between the helmet shell 91 and the mounting body 92.
[0104] On the other hand, if the coolant 2a is in the liquid phase and the coolant 2b is in the solid phase, the head 8 can be quickly cooled using the solid coolant 2b, which has high thermal conductivity. In other words, since the second cooling device body 1b is in contact with the head 8, the heat from the head 8 can be quickly absorbed by the solid coolant 2b, which has high thermal conductivity.
[0105] In this way, the coexistence of a highly flexible liquid-phase coolant 2a and a highly cooling-performance solid-phase coolant 2b makes it possible to achieve both flexibility and cooling performance.

[0107] The connector 7 is positioned between the first cooler body 1a and the second cooler body 1b, but the connector 7 may also be positioned on surfaces other than the opposing surfaces of the first cooler body 1a and the second cooler body 1b. For example, if the connector 7 is a band, the connector 7 is wrapped around the outer surfaces other than the opposing surfaces of the first cooler body 1a and the second cooler body 1b to connect the first cooler body 1a and the second cooler body 1b.
[0108] The connector 7 includes a first connecting portion 71 and a second connecting portion 72, but may be a single integrated component.

[0114] The thickness t2 of the housing portion 32b of the second cooler body 1b is smaller than the thickness t1 of the housing portion 32a of the first cooler body 1a, but the thickness t2 may be larger than the thickness t1, or the thickness t2 may be the same as the thickness t1.
[0115] The magnetic poles of adjacent first connecting portions 71 in the radial direction of the first cooler body 1a are different, and the magnetic poles of adjacent second connecting portions 72 in the radial direction of the second cooler body 1b are different, but the magnetic poles of adjacent first connecting portions 71 in the radial direction of the first cooler body 1a are the same, and the magnetic poles of adjacent second connecting portions 72 in the radial direction of the second cooler body 1b are the same.
[0116] The magnetic poles of adjacent first connecting portions 71 in the circumferential direction of the first cooler body 1a are different, and the magnetic poles of adjacent second connecting portions 72 in the circumferential direction of the second cooler body 1b are different, but the magnetic poles of adjacent first connecting portions 71 in the circumferential direction of the first cooler body 1a are the same, and the magnetic poles of adjacent second connecting portions 72 in the circumferential direction of the second cooler body 1b are the same.
[0117] The melting point of the coolant 2a in the first cooling device body 1a is different from, but may be the same as, the melting point of the coolant 2b in the second cooling device body 1b.
[0118] In the first cooling device body 1a, the second sheet 42a does not have to be flat, and may have multiple recesses formed in the opposite direction from the first sheet 41a. In this case, the partition portion 33a may be formed by joining the portion of the first sheet 41a between adjacent recesses 411a and the portion of the second sheet 42a between adjacent recesses.
[0119] In the second cooling device body 1b, the first sheet 41b and the second sheet 42b each have recesses 411b and 421b, respectively, but either the first sheet 41b or the second sheet 42b may be flat.
[0120] The shapes of the first cooler body 1a and the second cooler body 1b are not limited. The shapes of the first cooler body 1a and the second cooler body 1b may be polygons such as rectangles. The shapes, number, and arrangement of the housing sections 32a and 32b are not limited.

[0130] This configuration makes it easy to attach and detach the first cooling device body 1a and the second cooling device body 1b. Also, when the head cooling device 100 is installed on the protective helmet 90, hair is less likely to get tangled in the first connecting part 71 and the second connecting part 72 compared to using hook-and-loop fasteners.
[0131] (Aspect 5) In the head cooling device 100 described in any one of Embodiments 1 to 4, The first cooling device body 1a comprises a cooling agent 2a and an outer pack 3a that contains the cooling agent 2a.

The second portion 36a includes a plurality of divided bodies 37a that are divided in the circumferential direction, The first connecting portion 71 is located on each of the plurality of divided bodies 37a.
[0132] With this configuration, the first cooling device body 1a and the second cooling device body 1b can be firmly connected, and the head cooling device 100 can be stably installed inside the protective helmet 90.
[0133] (Aspect 6) In the head cooling device 100 described in any one of Embodiments 1 to 5, The second cooling device body 1b comprises a cooling agent 2b and an outer pack 3b that houses the cooling agent 2b.
