Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the case of using the above-mentioned wet towel for heat countermeasures, in the scorching sun, the effect fades along with the evaporation of the moisture impregnated in the towel in advance. Therefore, the effect is difficult to last, is limited, and is not suitable for long-term use.

[0006] Furthermore, the hat described in Patent Document 1 is intended to be worn inside a helmet, such as at a construction site. The cooling pack placed in the hammock portion provides a cooling effect for a certain period of time. However, helmets require a shell made of high-strength thermosetting resin or similar material to prevent impact, and therefore have poor ventilation. As a result, there is a problem in that it is difficult to expel the heat that accumulates on the head when used for a long time. In addition, a specially shaped cooling pack that fits the hammock portion is required.

[0007] Furthermore, the hat described in Patent Document 2 does not have a cooling pack inside the hat, and is also intended for use inside a helmet, so heat tends to accumulate at the top of the hat. Therefore, it cannot effectively cool the head and neck.

[0008] Thus, conventional technology had problems such as being unsuitable for prolonged use and causing discomfort due to stuffiness because it did not effectively release heat from the head.

[0009] In view of the above circumstances, the purpose of this invention is to provide a hat for heatstroke prevention that can cool the head and back of the neck for extended periods when going out or doing light work, thereby preventing heatstroke, while also suppressing stuffiness and providing excellent cooling sensation. [Means for solving the problem]

[0010] As a result of diligent research and development regarding the aforementioned problems, the inventor of this invention has devised the following groundbreaking hat for preventing heatstroke.

[0011] A first aspect of the present invention for solving the above problems is a hat for heatstroke prevention comprising a crown portion, a brim portion attached to the front end of the crown portion, and an extension portion extending from the rear end of the crown portion, wherein the hat has two lateral storage portions provided on each of the lateral sides of the crown portion for storing cooling packs, and a rear storage portion provided on the rear side or extension portion of the crown portion for storing cooling packs, and the crown portion, brim portion, extension portion, the two lateral storage portions and the rear storage portion are made of a breathable material that has breathability.

[0012] Here, the rear storage section may be provided from the rear side of the crown section to the extension section (spanning both the rear side of the crown section and the extension section).

[0013] According to this first embodiment, a hat for preventing heatstroke can be provided that can cool the head and the back of the neck, has excellent breathability, and is comfortable against the skin.

[0014] A second aspect of the present invention is a heatstroke prevention hat according to the first aspect, characterized in that the volume of the rear storage compartment is larger than the volume of the two side storage compartments.

[0015] This second embodiment can provide a heatstroke prevention hat that can cool the back of the neck for a longer period of time.

[0016] A third aspect of the present invention is a hat for preventing heatstroke according to the first or second aspect, characterized in that it has a string-like member, one end of which is connected to the end of one side of the crown portion, and the other end of which is connected to the end of the other side of the crown portion, and the string-like member is provided with an adjustment part that can adjust the length of the string-like member.

[0017] According to this third embodiment, it is possible to provide a hat for preventing heatstroke that can be securely fixed to the head.

[0018] A fourth aspect of the present invention is a hat for preventing heatstroke as described in the third aspect, characterized in that the two lateral storage sections and the rear storage section each have a quadrilateral shape in the planar direction, and at least one side of the quadrilateral has a storage opening that can be opened, and each storage opening is provided with a sealing member that can close a part of it.

[0019] According to this fourth embodiment, since each storage opening can be sealed, it is possible to prevent the cooling pack from falling out of the hat used to prevent heatstroke.

[0020] In the fifth aspect of the present invention, the breathable material is composed of mesh-like fibers, and the surface mesh size of the outer surfaces of the crown part, the two side accommodating parts, and the rear accommodating part is larger than the lining mesh size of the inner surface of the crown part, and it is in the heatstroke countermeasure hat according to the third aspect characterized by this.

[0021] According to such a fifth aspect, when the head and neck sweat or condensation forms inside the crown part, it can absorb the moisture, and it is possible to provide a heatstroke countermeasure hat that is dry and has a good texture.

[0022] In the sixth aspect of the present invention, the crown part, the flange part, the extended part, the two side accommodating parts, and the rear accommodating part are formed by sewing or adhering the same fabric, and it is in the heatstroke countermeasure hat according to the third aspect characterized by this.

[0023] According to such a sixth aspect, since the same breathable material is used, when the coolant is accommodated, the degree of shrinkage of the two side accommodating parts and the rear accommodating part becomes the same as that of the crown part, and it is possible to provide a heatstroke countermeasure hat that suppresses deformation.

[Modes for carrying out the invention]

[0025] The embodiments of the heatstroke prevention hat according to the present invention will be described below with reference to the drawings. However, the present invention is not limited to the embodiments described below.

[0026] (Embodiment 1) Figure 1 shows the left side view of the heatstroke prevention hat 1 according to Embodiment 1. As shown in this figure, the heatstroke prevention hat 1 is formed by cutting a breathable fabric into a predetermined shape and sewing or bonding multiple pieces together to create the hat shape. An opening 101 is formed at the lower end of the crown portion 10 that covers the head. Here, for the sake of simplicity, the direction in which the user's face is facing when wearing the heatstroke prevention hat 1 is defined as forward, the direction to the side of the user is defined as lateral, and the direction to the back of the user's head is defined as rear.

[0027] A brim portion 11 is provided at the lower front end of the crown portion 10, projecting approximately horizontally to block sunlight. An extension portion 12 is also provided at the lower rear end of the crown portion 10, extending in the direction of the extension line downwards from the lower end of the opening 101. The surface of the brim portion 11 is made of a breathable material, and a core material is placed inside the brim portion 11 to maintain its shape through its strength. The shape of the brim portion 11 is not particularly limited, nor are the shape and material of the core material. Examples of core materials include those made of resin in a roughly crescent shape.

[0028] The heatstroke prevention hat 1 has a bag-shaped side storage section 141 on the side 14 and a bag-shaped rear storage section 151 on the rear side 15 or extension 12, allowing for the storage of cooling packs 2 in each section.

[0029] By placing the cooling packs 2 in the lateral storage compartments 141 and rear storage compartment 151, respectively, and wearing the heatstroke prevention hat 1, the user's head and the back of their neck can be cooled from both lateral sides 14, the rear side 15, or the extended portion 12. In other words, the blood flowing through the blood vessels near the skin surface can be cooled simultaneously at three locations: the user's head and the back of their neck (multi-point cooling structure). As a result, the circulation of blood flowing through the blood vessels prevents the brain temperature from rising, and furthermore, circulation throughout the entire body effectively lowers the core body temperature, providing a cooling sensation.

[0030] Furthermore, string-like members 31 are attached to the approximate center of both sides of the opening 101. Specifically, one end of the string-like member 31 is sewn to the end near the center of one side of the crown portion 10, and the other end is sewn to the end near the center of the other side of the crown portion 10.

[0031] Furthermore, an adjustment part 32 is attached to the string-like member 31, which allows the length of the string-like member 31 to be adjusted. The adjustment part 32 is not particularly limited as long as it can adjust the length of the string-like member 31. For example, a cord stopper with a built-in spring can be used as the adjustment part 32.

[0032] The user can adjust the length of the string-like member 31 by adjusting the attachment position of the adjustment part 32 on the string-like member 31. As a result, the heatstroke prevention hat 1 can be securely fixed to the user's head.

[0033] Here, with the cooling packs 2 stored in the side storage compartments 141 and rear storage compartments 151 respectively, the center of gravity of the heatstroke prevention hat 1 changes depending on the arrangement and shape of each cooling pack 2, making it prone to instability. However, the string-like member 31 and adjustment part 32 allow the heatstroke prevention hat 1 to be securely fixed to the user's head. As a result, the heatstroke prevention hat 1 remains stable without falling off, even with changes in the user's movements or in windy conditions. The string-like member 31 and adjustment part 32 are particularly effective in situations where it is difficult to react quickly to the heatstroke prevention hat 1 falling off, such as in a work environment or for children and the elderly with limited physical strength.

[0034] The coolant 2 is not particularly limited, but examples include those made by housing a superabsorbent polymer (water-retaining agent) and water in a resin package and welding the four sides together, or commercially available ones (50g to 100g). Such a coolant 2 can be cooled by freezing in a freezer. The size of the coolant 2 is also not particularly limited, as long as it can be accommodated in the side storage section 141 and the rear storage section 151, respectively.

[0035] The breathable material constituting the crown portion 10, brim portion 11, extension portion 12, two lateral storage portions 141, and rear storage portion 151 is not particularly limited as long as it is breathable. An example of a breathable material is a three-layer double raschel mesh fabric. Double raschel mesh has a structure in which the outer layer is a coarse mesh, the inner layer is a relatively fine mesh, and the middle layer is woven in a honeycomb pattern with connecting threads on a raschel knitting machine. The fabric itself is several millimeters thick and has a high porosity, resulting in high cushioning, excellent breathability, and water absorption. The material of the double raschel mesh is not particularly limited, but examples include mainly polyester, nylon, polyurethane, and composites thereof.

[0036] By constructing the entire heatstroke prevention hat 1 with such a breathable material, heat from the head can be easily released to the outside, and it becomes less prone to stuffiness. In addition, the cushioning provides a close fit to the head. Furthermore, two lateral storage compartments 141 and a rear storage compartment 151 are provided on the outside of the crown 10, so that the cooling pack 2 does not come into direct contact with the skin of the head or neck. As a result, it is possible to prevent the head and neck from becoming too cold.

[0037] Furthermore, the mesh size of the inner surface of the crown portion 10 is smaller than that of the outer surface. As a result, the inside of the crown portion 10 that comes into contact with the head and skin has higher water absorption due to capillary action. On the other hand, the mesh size of the outer surface of the crown portion 10 is larger than that of the inner surface. As a result, moisture absorbed from the inside of the crown portion 10 evaporates more easily from the outer surface of the crown portion 10.

[0038] In this way, moisture on the inner surface (head) of the crown portion 10 can smoothly move to the outer surface of the crown portion 10, so that the skin-contacting side of the inner surface of the crown portion 10 can maintain a dry and comfortable feel.

[0039] Furthermore, the entire heatstroke prevention hat 1 is made of a highly flexible mesh fabric and has a brim 11 with a core material, making it easy to fold around the brim 11, resulting in a lightweight and compact design that is excellent in terms of storage and portability. In addition, the extended portion 12 also has the effect of blocking direct sunlight from reaching the back of the head and the back of the neck in the scorching sun, thus enhancing the feeling of coolness.

[0040] Figure 2 is a schematic front view of the heatstroke prevention hat 1 according to this embodiment. As shown in this figure, a left-side storage section 141a and a right-side storage section 141b are provided on the left and right side surfaces 14 of the crown section 10, respectively. After the string-like member 31 is brought into contact with the user's lower jaw, the position of the adjustment part 32 attached to the string-like member 31 is adjusted. As a result, the heatstroke prevention hat 1 can be securely fixed to the head by changing the length of the string-like member 31.

[0041] Figure 3 is a schematic view from the rear showing the configuration of the heatstroke prevention hat 1 shown in Figure 1. As shown in this figure, a rear storage section 151 is provided extending from the rear side surface 15 to the extended section 12.

[0042] Figure 4 is a schematic diagram showing the structure of the heatstroke prevention hat 1 in Figure 3, viewed from the opening 101 side of the crown portion 10. The crown portion 10 is the part that the user wears on their head. The inner surface 103 of the crown portion 10 is made of a breathable material with a finer mesh size than the outer surface 102. Examples of breathable materials include the three-layer double raschel mesh lining mentioned above.

[0043] Figure 5 shows an example of a mesh dimension configuration for a breathable fabric. The outer surface of the crown portion 10 shown in Figure 1 is the mesh 102 fabric shown in Figure 5(a). The part that comes into contact with the head, shown in Figure 4, corresponds to the mesh 103 fabric in Figure 5(b). The mesh dimension M1 of the mesh 102 on the outer surface in Figure 5(a) is larger than the mesh dimension M2 shown in Figure 5(b) (M1 > M2).

[0044] In other words, the heatstroke prevention hat 1 is constructed such that the mesh size of the fabric closest to the user's skin (the breathable material on the inside of the crown 10) is smaller than the mesh size of the breathable material on the outside of the crown 10. As a result, sweat on the skin surface is absorbed into the breathable material on the inside of the crown 10 by capillary action. Subsequently, the moisture (sweat) inside the breathable material on the inside of the crown 10 moves toward the outer surface of the crown. Then, it evaporates on the outer surface of the crown, where the mesh size is larger. Due to this action, the contact surface between the inner surface of the crown 10 and the skin remains dry and comfortable.

[0045] Figure 6 is a schematic left side view showing the configuration of the heatstroke prevention hat 1 shown in Figure 1. This shows the case when the user wears the heatstroke prevention hat 1 such that the front side surface 13 of the heatstroke prevention hat 1 is positioned above the rear side surface 15. The contact area of ​​the rear storage section 151 with the rear lower part 16 is wider than when worn as in Figure 1, making it easier to feel cool. Even in this case, the heatstroke prevention hat 1 can be stably fixed to the head by the string-like member 31 and the adjustment part 32.

[0046] Figure 7 is an external view of the compartment for the cooling pack 2 of the heatstroke prevention hat 1 shown in Figure 1. This figure shows one side compartment 141 as an example. The other side compartment 141 and the rear compartment 151 are similar. The side compartment 141 is formed, for example, by sewing the same breathable material to the crown 10. The seams 143 of the side compartment 141 can be sewn with thread 144 using a zigzag stitch with an overlock sewing machine while using bias tape or the like to prevent fraying. By leaving at least one side of the quadrilateral side compartment 141 as an opening 142 that is not sewn, it is possible to insert and remove the cooling pack 2 into the side compartment 141. The shape of the corners of the quadrilateral side compartment 141 may include rounded or cut corners.

[0047] Furthermore, because the breathable crown portion 10 and the side storage portion 141 are made of the same material, their degrees of shrinkage are consistent. As a result, it is possible to prevent the overall shape deformation of the heatstroke prevention hat 1 depending on whether or not the cooling pack 2 is present. Note that the sewing method is not limited to this.

[0048] Furthermore, by using different colors for the crown portion 10 and the side storage portion 141, even though they are made of the same breathable material, the design of the heatstroke prevention hat 1 can be improved.

[0049] Furthermore, since the two lateral storage compartments 141 and the rear storage compartment 151 are provided on the outside of the crown portion, if the temperature of the coolant 2 changes to near room temperature and the cooling effect is reduced, it is possible to easily replace it with another coolant that has a cooling effect.

[0050] By providing a sealing member 4, such as a hook-and-loop fastener, on the contact surface between the crown portion 10 and the side storage portion 141, a portion of the storage opening 142 can be closed. As a result, the ice pack 2 can be prevented from falling out. Here, the same effect can be obtained if the sealing member 4 is a hook-and-loop fastener, slide fastener, button, snap fastener, etc. It goes without saying that the storage opening 142 of the side storage portion 141 may be on the side as well as the top.

[0051] Figure 8 is a schematic cross-sectional view of the heatstroke prevention hat 1 with the cooling packs 2 stored in the side storage compartments 141 and rear storage compartment 151. Figure 8(a) is a schematic cross-sectional view of the side storage compartment 141 in the A-A section of Figure 7. On the other hand, Figure 8(b) is a schematic cross-sectional view of the rear storage compartment 151 in the B-B section of Figure 3.

[0052] In Figure 8(a), the width of the lateral storage section 141 is 5a and the height is H1, while in Figure 8(b), the width of the lateral storage section 151 is 5b and the height is H2, with H2 being larger than H1. In other words, the volume of the rear storage section 151 is larger than that of the lateral storage section 141. For example, the lateral storage section 141 can accommodate one ice pack 2, while the rear storage section 151 can accommodate two ice packs (2a, 2b). As a result, the ice packs 2 in the rear storage section 151 enable long-term cooling of the back of the head and the back of the neck near the carotid artery, where heatstroke prevention is most effective.

[0053] (Other embodiments) Although the above explanation assumes that coolants are placed in all coolant compartments, the effects of this invention can be achieved even if only parts of the coolant compartments are used, depending on the situation.

[0054] Furthermore, this invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, numerical values, form, number, and placement of each element in the embodiments described above are arbitrary as long as they can achieve the effects of this invention, and are not particularly limited.
