【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 1, reference numeral 1 indicates a part of a sun visor as a hat body. An air cooling type cooling mechanism 2 is provided inside the front portion 1a which is the front portion of the sun visor 1 corresponding to the forehead portion of the head portion. As shown in FIG. 3, the cooling mechanism 2 is composed of heat radiation blocks 20 connected to each other. The cooling block 20 has a cylindrical connecting projection 20a at one end and a connecting recess 20b at the other end with which the projection 20a is rotatably engaged. On one surface of the cooling block 20, vertically extending air circulation portions 20c and cooling fins 20d are alternately formed, and the back surface side of the fins serves as a contact portion 20e that contacts the forehead portion. ..

The individual cooling blocks 20 are rotatably connected to each other, and then fixed to the front portion 1 a by using a stopper 21 (see FIG. 1). It goes without saying that the blocks are connected so that they do not shift in the vertical direction. Further, when the contact portion 20e of the cooling block 20 is formed to have a relatively rough surface or an uneven surface, the contact portion and the forehead do not come into close contact with each other, and discomfort is reduced.

The cooling block 20 is formed, for example, by cutting an aluminum or its alloy drawn out into a predetermined length. As a material for this cooling block, a synthetic resin having good heat conduction may be selected, and in this case, if it is a flexible material, it does not become a block and continues to a predetermined length. Is also good. Further, although the example shown in FIG. 1 shows the cooling mechanism 2 having a length in contact with the forehead part, the cooling mechanism 2 may be formed in a length in contact with the entire circumference of the head.

Next, referring to FIG. 2, another example of the air-cooling type cooling mechanism 2 will be described. The cooling mechanism 2 comprises a cooling plate 22 formed by bending a thin aluminum plate into a corrugated cross section. As shown in FIGS. 4 and 6 (b), the cooling plate 22 is attached to the sun visor 1 with one surface 22a abutting on the upright portion 1a. The cooling plate 22 bent into a square waveform is provided with an air circulating portion 22b extending in the vertical direction and a contact portion 22c contacting the forehead portion Z.

As shown in FIG. 6, a skin 23 such as a cloth may be attached to the contact portion 22c for avoiding direct contact with the forehead portion Z and enhancing texture. The skin 23 is preferably made of a material as thin as possible so as not to reduce the cooling effect.

As shown in FIG. 13, the cooling plate 22 is provided with a groove 22d for increasing the cooling effect and for promoting the diffusion of the cooling water in the water cooling type cooling mechanism described later. A cooling plate 22A shown in FIG. 13 (a) has parallel grooves 22d formed therein, and a cooling plate 22B shown in FIG. 13 (c) has mesh grooves 22d formed therein. The cooling plate 22 is formed with grooves when it is pressed into a corrugated shape, or is bent into a corrugated shape after forming the grooves. Although the groove 22d shown in FIG. 13B is formed on one surface of the cooling plate, the groove 22d may be formed on both surfaces.

The cooling plate 22 may have a sectional shape as shown in FIG. 10, which is formed by bending a plate material having good heat conduction. In the examples shown in (a), (b), and (e), the surface that contacts the forehead part Z is not selected, but in the examples shown in (c) and (d), the arc surface side is the contact part. There is less stickiness due to sweating. Further, the cooling plate may be used alone, but for example, a plurality of cooling plates shown in (a) and (b) of the same drawing may be stacked, and ones shown in (a) and (d) may be stacked. May be stacked on top of each other. It goes without saying that no matter which cross-sectional shape shown in FIG. 10 is selected, a bent shape that does not pinch the hair is selected. Further, regardless of the cross-sectional shape, a groove 22d (see FIG. 13) for diffusing water or sweat may be formed on one side or both sides. Whichever cross-sectional shape is selected, the air circulation portion is formed so as to extend in the vertical direction, but in order to reduce the circulation resistance of the air in the air circulation portion, the side from the forehead portion You may incline so that it may incline backwards toward the head. That is, the air circulation portion provided along the up-down direction also includes an inclined form.

In the cooling plate 22 shown in FIG. 4, the cloth 23 may be formed of an aluminum plate and the surface 22a may serve as a contact portion to increase the heat radiation area. Such a structure for increasing the heat dissipation surface can also be applied to each cooling plate shown in FIG.

Next, the water cooling type cooling mechanism will be described. This cooling mechanism aims to improve the cooling effect by supplying water to the cooling block or cooling plate of the cooling mechanism already described and utilizing the heat of vaporization of water. 5 and 6 (a), a water supply unit 24 is arranged between the cooling plate 22 having a rectangular corrugated cross-sectional structure and the upright portion 1a. The water supply unit 24 includes a water supply tank 24a for storing water and a water retention member 24b stored in the tank for holding water. The water supply tank 24 a is, for example, a flexible container made of synthetic resin and is arranged adjacent to the cooling plate 22. In this case, the water supply tank 24a and the cooling plate 22 are formed with communication windows 24aa, 22d facing each other as shown in FIG. The water supply tank 24a and the cooling plate 22 are integrated with each other, and the water retained in the water retaining member 24b moves to the surface of the cooling plate 22 through the communication windows 24aa and 22d. The water that has moved to the surface of the cooling plate 22 is vaporized by the flow of air that flows through the air circulation unit 22b.

As shown in FIG. 6, the water supply tank 24a and the cooling plate 22 are connected to the sun visor 1 by engaging the lower clip 1b and the upper clip 1c formed on the upright portion 1a with the air circulation portion 22b. It is detachably attached. Although the illustrated clip is formed integrally with the sun visor 1, an example in which the clip is attached may be another type of member such as a magic tape (trade name) as a mounting member for the cooling mechanism. Further, the cooling mechanism does not necessarily have to be detachable, and may be fixedly attached to the cap body.

The water supply tank 24 a shown in FIGS. 6 and 8 has a side wall 24 ab between the cooling plate 22 and the side wall 24 ab, and supplies water to the air circulation unit 22 b through a communication window 24 aa formed in the side wall 24 ab. However, as shown in FIG. 11, the side wall 24ab may be eliminated and the one side surface 24ba of the water retaining member 24b may be directly exposed to the air circulation portion 22b. However, it should be noted that if the exposed surface of the one side surface 24ba is too large, the amount of water evaporated from the relevant portion will increase.

A groove 22d as shown in FIG. 13 is formed on the surface of the cooling plate 22 so that the water stored in the water retaining member 24b can be diffused better on the wall surface of the air circulation portion 22b. Further, as shown in FIG. 9, the water retained in the water retaining member 24b is in contact with one side surface 24ba of the water retaining member 24b so that the water can be easily attached to the inner surface of the air communicating portion 24b. It is also possible to provide a member 25 that exhibits a capillarity like an applied cloth.

As shown in FIGS. 11 and 12, a water supply port 24a c is formed in the upper part of the water supply tank 24a. The water supply port 24ac is closed by caps 24ad and 24ae after water supply. As shown in FIG. 9 and FIG. 11, when a structure in which a part of the water retaining member 24b faces the air circulation portion 22b is adopted, water can be supplied from the air circulation portion 22b, so the water supply port and the cap are It is not necessary to provide it in particular.

The water retention member 24b is filled in the water supply tank 24a, and is composed of a member that exerts a water retention capacity by a capillary phenomenon even if it is not compressed and expanded like a fiber made of natural fibers or synthetic fibers. When the water supply tank 24a is made flexible, it can be sucked into the tank by a pump action if it is placed in water or in a water flow and then compressed and restored.

The water supply unit 24 in the illustrated embodiment is provided with a water supply tank 14a for storing water, but without providing a tank, for example, a cooling plate having a sectional structure shown in FIGS. 10 (a) and 10 (b). It is also possible to superimpose each other and hold the water retention member between each other to form a water supply part. Further, in FIGS. 9 and 11, the water retaining member may be introduced into the air circulation portion 22b which is open so as to face the water retaining member 24b.

In FIGS. 5 and 6 (a), reference numeral 23 indicates a cloth attached to the contact portion 22c. Instead of the cloth 23, short fibers may be planted to improve texture and avoid stickiness of the forehead.

Now, the operation of the embodiment configured as described above will be described. First, in the case of the air cooling type cooling mechanism 2, when the sun visor 1 is covered, the contact portion 20e of the cooling block 20 (see FIG. 3) and the contact portion 22c of the cooling plate 22 come into contact with the forehead portion Z (see FIG. 2). To do. When you first wear the sun visor, you will feel “cool” due to the coldness of the cooling plate, but over time, the contact part absorbs the heat of the forehead part and its temperature rises. When moving around with the sun visor covered, air circulates through the air circulation portions 20c (see FIG. 3) and 22b (see FIG. 2) to cool the contact portions. Even when stationary, if there is wind, the air circulates in the air circulation section and cools the contact section. Therefore, even when wearing the hat, the forehead part Z maintains a "cool" feel due to the cooled contact part. Experimental results on this point will be described later.

Next, when the water cooling type cooling mechanism is provided, the water stored in the water retaining member 24b is vaporized in the cooling plate 22 and the air circulation portion of the cooling block 20, and the contact portion is cooled by the heat of vaporization. The heat of the forehead part Z is dissipated more efficiently. When moving over the sun visor 1, the amount of air circulation in the air circulation portion increases, and the heat dissipation effect further increases. The results of this experiment will also be described later.

FIG. 14 shows a commercially available sun visor without a cooling mechanism (hereinafter referred to as “sun visor A”), an air-cooled type (hereinafter referred to as “dry type”) and a water example type (hereinafter referred to as “sun visor A”) in the same product as this sun visor. The figure shows the temperature change of the forehead temperature detected for each minute when each cooling mechanism (referred to as "wet type") is provided. For temperature detection, a digital display type industrial temperature measuring instrument was used. The sun visor A was covered with the sweat removal part of the sun visor A overlaid on the temperature sensor attached to the forehead Z (see FIG. 2). The sun visor equipped with a dry type cooling mechanism (see Fig. 2) and the sun visor equipped with a wet type cooling mechanism (see Fig. 6 (a)) consist of the contact of the cooling plate 22 on the temperature sensor attached to the forehead. The portion 22c was overlapped and covered.

In FIG. 14, time is plotted on the horizontal axis and temperature is plotted on the vertical axis. At time t0, the sun visor is worn while sitting in a chair (resting state) indoors, and at t1, the breeze by the fan is taken as the head. It refers to the time when the fan starts to hit from the front, t2 refers to the time when the fan is switched to strong wind, t3 refers to the time when the fan blows air off, and t4 refers to the time when you start walking indoors. The room temperature during the experiment was 23 degrees Celsius (the same applies below), and the surface temperature of the forehead with the sun visor attached was 31 degrees. The alternate long and short dash line shows the temperature change on the forehead surface when the sun visor A is covered, and the solid line is provided with a dry type cooling mechanism including a cooling plate with the cloth 23 removed from the cooling plate having a cross-sectional shape as shown in FIG. Temperature change of the forehead surface (cooling plate) when covered with a sun visor, and the broken line represents the forehead when covered with a sun visor equipped with a wet type cooling mechanism as shown in FIGS. 6 (a) and 8 ( It shows the temperature change of the cooling plate). As the cooling plate, an aluminum plate having a thickness of 0.3 mm was bent and used.

As can be seen from the alternate long and short dash line in FIG. 14, the temperature of the forehead Z starts to rise about 3 minutes after t0 when the sun visor A is covered, and after 7 minutes, the temperature of about 32 degrees. Keep the degree and move on. When the strength of the fan was changed to strong wind (t2), it decreased to about 30 degrees after about 5 minutes. About 6 minutes after turning off the fan (t3), the temperature of the forehead rose to the original 32 degrees. This temperature hardly changed even after starting walking at t4. As can be seen from the alternate long and short dash line in FIG. 14, in the sun visor A that does not have a cooling mechanism, the temperature of the forehead slightly decreases while the strong wind from the fan is being applied, but a slight breeze or movement of the air to the extent of walking. Shows that the temperature cannot be lowered.

The temperature change of the dry type sun visor with a cooling mechanism shown by the solid line drops sharply to about 26 degrees close to room temperature immediately after mounting due to the temperature of the cooling plate itself, but it is 2 minutes, 5 minutes, 7 minutes. As the temperature rises, the temperature gradually rises, and after about 10 minutes, the temperature becomes equal to the temperature of the forehead (cooling plate) and the temperature shifts. When a slight wind from the fan was applied to the forehead at t1, the temperature dropped to about 26 degrees in about 5 minutes, and I was able to experience a considerable coolness. When the fan was switched to strong wind at t2, the temperature dropped to about 25 degrees after about 2 minutes. When the fan was stopped at t3, the temperature began to rise after 1 minute and reached about 31 degrees, which was the same as the stationary state, about 10 minutes after the stop.

When I started walking inside the room at t4, the temperature began to drop around 1 minute, and reached about 27 degrees in about 8 minutes from the start of walking. It can be seen from the solid line in Fig. 14 that the sun visor equipped with the air-cooled cooling mechanism has a "feeling of chill" immediately after mounting in the stationary state, but after about 10 minutes, the temperature of the forehead becomes the same. As a result, the continuous cooling effect cannot be expected. However, it is shown that the temperature of the contact portion 22c of the cooling plate 22, that is, the forehead is reduced to about 27 degrees when the air flow occurs in the air circulation portion 22b (see FIG. 2) due to a light wind or walking. It means that you can experience a considerable "coolness".

Next, a sun visor provided with a wet type cooling mechanism will be described. In this case, a cooling plate having a cross-sectional shape as shown in FIG. 10 (e) is used as the cooling plate, and absorbent cotton is filled between this plate and the sun visor front part 1a so that the tap water is not contained in it. It was In the case of the wet type, as shown by the broken line, the temperature dropped sharply to about 24 degrees immediately after mounting, but increased to about 30 degrees after about 11 minutes elapsed. The reason why the wet type calms down at a temperature lower than that of the dry type (solid line) is that the phenomenon of temperature decrease due to the heat of vaporization of water occurs even in a stationary state.

When a slight wind of the fan was applied at t1, the temperature of the cooling plate (forehead) dropped to slightly less than 26 degrees after 6 minutes. When the fan was switched to strong wind at t2, the temperature dropped to less than 25 degrees Celsius and I felt a considerable "cool feeling." When fan blowing was stopped at t3, the temperature rose to 29 degrees after about 10 minutes, and then changed to this state. In this case, the change in temperature was much more gradual than that of the dry type.

When I started walking at t4, the heat of vaporization increased due to the flow of air through the air circulation portion 22b, and after about 7 minutes, the temperature of the cooling plate decreased to about 26 degrees. When comparing the difference in temperature change between the wet type and the sun visor A, there is a temperature difference of 2 to 6 degrees, but this temperature difference was felt as being quite cool. In addition, when comparing the wet type and the dry type, there is no large temperature difference between the sun visor A and air blown by a fan, walking, or air flowing through the air circulation part. There was only a similar difference. However, in hot weather where the difference between the ambient temperature and the surface temperature of the forehead (cooling plate) appears significantly, it is considered that the structural difference between the dry type and the wet type appears significantly.

In the case of the water type, the injected tap water was about 30 cc, but it remained sufficiently moist even after about 1 hour required for the experiment. In a room at a room temperature of 23 ° C., it remained moist even after 5 hours, and it took about 12 hours to completely dry it. It is not common to continue sports or work for 5 hours without a break, and it is quite possible to supply water during the breaks. Therefore, the water-type water supply tank 24b is sufficient if it has a capacity of storing approximately 25 to 30 cc of water.

Next, referring to FIG. 15, a dry type used alone with the cooling block 20 shown in FIG. 3 and a cotton block are brought into contact with the surface of the cooling block 20 opposite to the contact surface 20c, and tap water is applied thereto. The experimental results using the wet type impregnated with are explained. As a water-type cooling mechanism, a plurality of aluminum cooling blocks 20 each having a length of 30 mm, a width of 20 mm, and a thickness of 10 mm, which are drawn and cut, are connected to each other in such a length as to cover the forehead and the temporal region. .. An absorbent cotton block having a thickness of 8 mm was used as the water retaining member. At t0 when the sun visor was attached, the room temperature was 23 degrees, and the temperature of the forehead (contact portion 22c of the cooling block) was 31 degrees.

In FIG. 15, the solid line shows the temperature change of the dry type cooling mechanism, and the broken line shows the temperature change of the wet type cooling mechanism.

The temperature change of the dry type sun visor with a cooling mechanism shown by the solid line drops sharply to about 24 degrees near room temperature immediately after mounting due to the temperature of the cooling plate itself, but after about 8 minutes, the forehead (cooling plate The temperature shifts to about 30 degrees, which is slightly lower than the temperature in). When a slight wind from a fan was applied to the forehead at t1, the temperature dropped to about 27 degrees in about 6 minutes. When the fan was switched to strong wind at t2, the temperature dropped to about 26 degrees after about 2 minutes had elapsed. When the fan was stopped at t3, the temperature began to rise after about 1 minute, and about 12 minutes after the stop, the temperature reached about 30 degrees, which was the same as at rest.

When I started walking inside the room at t4, the temperature started to drop around 1 minute, and reached about 29 degrees 2 minutes after starting walking.

In the case of the wet type, as shown by the broken line, the temperature sharply dropped to about 21 degrees below room temperature immediately after mounting, but increased to about 29 degrees about 15 minutes after mounting (see t1). The reason why the wet type calms down at a temperature lower than that of the dry type (solid line) is that the phenomenon of temperature decrease due to the heat of vaporization of water occurs even in a stationary state.

When a slight air flow of a fan was applied at t1, the temperature of the cooling plate (forehead) gradually decreased, and it decreased to 25 degrees after 7 minutes. At t2, when the wind of the fan was switched to strong wind, the temperature dropped to about 24 degrees and I felt a considerable “cool feeling”. When the blow of air by the fan was stopped at t3, the temperature rose to 29 degrees after about 18 minutes, and then changed to this state.

When I started walking at t4, the generation of heat of vaporization increased due to the air flowing through the air circulation portion 22b, and the temperature of 29 degrees fell to about 28 degrees after about 2 minutes. When comparing the difference in temperature change between the wet type and the dry type, a temperature difference of 1 to 2 degrees occurred. The difference between the case where the cooling block 20 is used and the case where the cooling plate 22 is used is that the former has a gradual rise and fall when air flow occurs and changes due to the large heat capacity, and the latter. Is that the smaller the heat capacity, the faster the rise and fall.

Next, referring to FIG. 16, the results of experiments outdoors will be described. In this experiment, a commercially available sun visor A having no cooling mechanism and a sun visor equipped with an air cooling type cooling mechanism including a cooling plate 22 formed by bending an aluminum plate as shown in FIG. It was carried out in an environment where the weather was fine and cloudy with occasional breeze. The sun visor was installed at time t0, running started at t1 and stopped at t2.

In FIG. 16, the alternate long and short dash line shows the temperature change of the sun visor A, which was 26 degrees lower by 2 degrees from the forehead temperature about 5 minutes after mounting. On the other hand, in the case of the air-cooling type cooling mechanism shown by the solid line, it stabilized at a temperature of 22 degrees in about 4 minutes after mounting the sun visor. When the running was started at t1, the circulation of air in the air circulation portion 22b was promoted, and the temperature started to decrease after 1 minute and decreased to 18 degrees after about 2 minutes. It is considered that a large temperature drop was realized because the amount of air that cooled the cooling plate increased during running. The temperature of 18 degrees is about 8 degrees higher than that of the sun visor A, and it was recognized that the presence of the outdoor cooling mechanism has a significant meaning.

When the running was stopped at t2, the temperature gradually increased as the flow rate of the air decreased, and after 8 minutes, the temperature became stable at 22 ° C., which was the same as before the start of running. From the results of this outdoor experiment, it was found that even in a stationary state, if there was a slight breeze, there was a temperature drop of about 4 degrees compared to the case without a cooling mechanism, and walking caused that much air to the air flow section 22b. Since the inflow of air increases, a temperature drop of 4 degrees or more can be expected.

In the illustrated embodiment, the sun visor is used as the hat main body, but if a structure that does not hinder the air circulation of the air circulation portions 20c and 22b is adopted, the work having a portion that covers the top of the head is performed. Of course, the present invention can be applied to a hat, a helmet and the like.

Further, as shown by reference numeral 1b in FIG. 1, ventilation holes may be provided in the front standing portion 1a of the hat body, and air may be introduced into the air circulation portion through the holes 1b. It goes without saying that the ventilation hole 1b may be provided not only in the full-width portion but also in the portion corresponding to the full-width portion to the temporal region.
