Description

[Detailed description of the invention]

[0001]

[Technology to which the invention belongs]

 The present invention relates to an improvement of a headwear, particularly a hat or a helmet having a function of cooling a head.

[0002]

[Prior art]

 Conventional hats or helmets are intended to protect the head from falling or falling objects or to protect the head from direct sunlight. Several improvements have been proposed for helmets worn by people engaged in various tasks under the scorching sun for the purpose of cooling the heads of workers. For example, a helmet equipped with an electric fan to cool the worker's head, a thermoelectric cooling device using semiconductors, Japanese Patent Publication No. 61-231205, Japanese Patent Publication No. 64-20310, Japanese Patent Publication No. For example, there is a structure in which the cooling medium described in US Pat. No. -11004 is filled in the inside of the cap and the head is directly contacted with the cooling medium to cool the head.

[0003]

[Problems to be solved by the invention]

 However, the helmet in the conventional technology has a very complicated structure, generating noise, generating vibration, and the weight of the device is so heavy that the burden on the neck and shoulders is too great. Due to the contact, there are problems such as the occurrence of head damage due to excessive cooling and the high manufacturing cost, and further, this kind of complicated structure is unnecessary when working at room temperature. .

[0004]

[Means for solving the problem]

 Therefore, in the present invention, as shown in Fig. 1, a detachable hammock is attached to a hat or a helmet, an air layer is provided between the hat and the head, and a refrigerant is disposed in the air layer. The above problem is solved by providing a cooling hat characterized by maintaining a comfortable temperature on the face, frontal region, parietal region, and occipital region due to convection of cold air generated by the cooling convection. Here, the hat means all that is worn on the head, and the hammock means all that has a structure that creates an air layer between the hat and the head.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the invention will be described based on examples with reference to the drawings. FIG. 1 is a central sectional view of an A type cooling hat, FIG. 2 is a bottom view thereof, FIG. 3 is a central sectional view of a B type cooling hat, FIG. 4 is a bottom view thereof, and FIG. FIG. 6 is a cross-sectional view of the refrigerant package, and FIG. 6 is a cross-sectional view of the refrigerant mounting device.

FIG. 1 shows that an air layer (3) is provided between a hat or a helmet (1) and a head by attaching a detachable hammock (2) to the hat or a helmet (1). A device (6) for mounting a refrigerant body is provided on the hammock (2), and a refrigerant body (4) is mounted. The refrigerant (4) is provided with a hygroscopic material (8). As a result, the air in the air layer (3) is cooled, convection occurs, and the cool air drops, so that the entire head can be maintained at a comfortable temperature.

[0007] The heat insulating material (7) is attached for the purpose of preventing cool air in the air layer (3) from dissipating from the surface of the hat or helmet (1). As a result, the cool air in the air layer is maintained for a longer time.

[0008] By processing or covering the hammock (2), the refrigerant mounting device (6) and the headband (9) with a material having a high thermal conductivity, the cool air in the air layer (3) can be quickly removed. It can be transmitted to the whole head uniformly.

The water droplets that have condensed on the refrigerant (4) are absorbed by the hygroscopic material (8). When this moisture evaporates, it takes away the heat of vaporization from the surroundings, so the effect of keeping the cool air in the air layer longer can be expected.

[0010] By securing a gap between the hat or helmet (1) and the headband (9), the cool air drops and the cooling effect spreads to the face, frontal region, crown, left and right side head, and occipital region. You can let me do it.

FIG. 3 shows a cooling hat having a structure in which a hat or helmet (1) and a headband (9) are brought into close contact with each other so that cold air is sealed in the hat and the cooling effect of the head is maintained for a longer time. is there.

[0012] By attaching a hammock (2) equipped with the device according to claim 1, 2, 3, 4, 5, 6, 7, 8 to a variety of ready-made hats or helmets, all the hats or helmets are provided. Can be easily modified into a cooling hat.

FIG. 5 shows an example of a package of a refrigerant body which can be attached and detached with one touch. As shown in the figure, a concave groove is provided on the entire periphery of the side surface of the package. Since the cooling medium (4) is liquid at room temperature and is housed in a bag of soft synthetic resin, it can be easily attached to and detached from the package. As shown in the figure, the hygroscopic material (8) is first charged into the package, and then a soft synthetic resin bag containing the refrigerant (4) is charged, and the bag is cooled and solidified in a refrigerator or freezer. Just before using the helmet or the helmet (1), attach this package to the refrigerant mounting device (6) for use. After being used for a certain period of time, the refrigerant liquefies and loses its effectiveness. Therefore, it is removed with one touch from the refrigerant mounting device, re-entered in a refrigerator or freezer, frozen and solidified, and used repeatedly.

[0014] The refrigerant (4) may be liquefied at room temperature, or may utilize an endothermic reaction when one kind of an inorganic compound or a mixture of two kinds of solid powders is dissolved in water. . In such a case, the compound and water are sealed in a bag of soft synthetic resin separated and stored by a partition wall, and the partition wall is broken immediately before use, loaded into a package shown in Fig. 5, and mounted on a refrigerant mounting device for use. I do. After use, it is in a liquid state and can be frozen and reused in a refrigerator or freezer.

FIG. 6 shows an example of the coolant mounting device. As shown in the figure, a convex ring is provided on the entire periphery of the refrigerant mounting device (6), and when the refrigerant package (5) is attached, both concaves and convexes are fitted to prevent the falling off. It is.

[0016]

[Effect of the invention]

 As described above, in the present invention, a cooling medium such as water, which can be obtained at low cost and can be used repeatedly, is disposed in an air layer formed by a hat or a helmet and a hammock, and this air layer is cooled and generated. Since the entire head can be uniformly cooled to a comfortable temperature by the convection of air, an inexpensive cooling hat can be provided. Also, by processing or covering the hammock, the refrigerant mounting device, the headband, etc. with a soft and elastically deformable high thermal conductivity material, the cool air of the refrigerant can be quickly dispersed and the head can be cooled uniformly. Can be done. In addition, by setting the weight of the cooling medium to, for example, about 120 g, pressure is not applied to the neck, shoulders, etc., so that it can be used safely and comfortably without fatigue for a long time. In addition, heat dissipation is prevented by installing heat insulating material on the inner surface of the hat or helmet, so that limited heat can be used effectively. In addition, this heat insulating material can also play a role in preventing impact in the event of a crash. In addition, since the head is not in direct contact with the cooling medium, the head can be used comfortably without the risk of head injury due to excessive cooling. Another characteristic of this cooling hat is that it can provide an ideal cooling hat that is completely the same as a normal hat or helmet when working or working at room temperature unless a refrigerant package is installed. It is.
