Description

  The present invention relates to a ventilation aid for a hat that takes in outside air inside the crown portion of the hat, improves the ventilation inside the crown portion, and prevents the cap user's head from becoming stuffy.

  There are currently hats devised to take outside air inside the crown, improve the ventilation inside the crown, and eliminate the stuffiness.

In the conventional hat, the lower edge part inside the crown part, which is constituted by a sweat band or the like, is in close contact with the user's forehead, temporal region, and occipital region, so it is difficult for outside air to enter the inside of the crown part. As a result, the head was stuffy and the user felt uncomfortable.
In order to improve the ventilation inside the crown part, there are hats that are made of mesh-like material to form the crown part, but the part covering the forehead part of the crown part loses its shape as seen from the front. For the purpose of not having it, and for the purpose of making the embroidery etc. look beautiful, the hat is made of a reinforced material from the back. However, there were many hats with poor ventilation in the forehead.
The forehead had an important role of sweating at high temperatures, lowering the temperature of the forehead with the heat of vaporization generated when the sweat evaporated, and thus adjusting the temperature of the entire head. However, when a hat is used, in the forehead where the hair is not growing, the close contact with the lower edge of the hat is high, so ventilation is poor and sweat does not easily evaporate. There wasn't.
Even if it is a sun visor where most of the head is not covered with the crown part, since the sweat removing band etc. formed on the lower edge of the sun visor adheres to the user's forehead part, there is no air circulation in the forehead part, I felt uncomfortable.
In addition, since the heel part of the cap is formed slightly obliquely downward, the air from the front often escapes to the upper side of the heel part, and as a result, the air around the forehead part located at the lower back of the heel part Distribution was not good. In order to avoid this problem, a hat may be put on with the buttock on the rear side even though the buttock is required on the front side for light shielding. For this reason, a hat with good ventilation at the forehead has been desired.
In addition, securing a route that guides the exhaust from the inside to the outside of the crown part affects whether or not the outside air can be efficiently sent to the inside of the crown part, but a hat that does not secure a sufficient exhaust route. There were many.

In the type of Patent Document 1, a ventilation hole is provided on the inner side of the hat, and the outside air entering from the ventilation hole has an effect of improving the air circulation inside the hat (except for the forehead).
However, since this vent has no opening at the position where it comes into contact with the user's forehead, the forehead is in close contact with the vent itself instead of being in close contact with the cap, and air taken in from the outside is in the forehead. There is a drawback that it is not possible to directly hit the part, and the temperature adjustment of the forehead part by the heat of vaporization cannot be expected.
In addition, when the heel moves forward with the movement of the user, a vigorous air flow occurs on the upper side of the heel due to the structure where the tip extends downward, and there is not much air flow on the lower side of the heel. Does not occur. In the type of the above-mentioned Patent Document 1, the air intake is configured to be opened downward in addition to the bottom of the tub where there is little air flow, and the intake is open downward. There is a drawback that the outside air cannot be efficiently fed into the inside of the crown portion.
The same reference also introduces a hat that has a convex part on the inner forehead of the hat's forehead and creates a space between the forehead and the hat. However, there is a drawback in that it is not structured to reliably hold the space that is an intake port for outside air.
Also in this type, the air intake is open to the bottom, further down, and does not protrude outside, so active air can be taken into the hat. Couldn't hope.
Further, no particular consideration is given to the route for guiding air from the inside to the outside of the crown portion.

Moreover, in the type of patent document 2, although the ventilation part as an opening part for taking in external air is formed by the ventilation band which has air permeability between the inner side of a crown part, and the perspiration | capture-removal band, The air intake is located at the farthest bottom of the tub and is open downwards, so it is not open toward the direction of air flow. I couldn't get into the typical hat.
Furthermore, there has been a drawback that stuffiness at the forehead where the sweat removing band directly contacts the forehead is not eliminated.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the cap ventilation aid 1 includes a main body 2 having a main body body 2DB and a plurality of main body frame portions 2G that are formed integrally with the main body body 2DB and come into contact with the forehead portion. Prepare.
Since the main body frame portions 2G are separated from each other, an opening or an open space (cavity) is formed in the main body 2.
When the main body 2 is set on the forehead portion with the opening portion facing the forehead portion, the forehead cavity 22 is formed by the main body frame portion 2G, the main body trunk portion 2DB, and the forehead portion.
The main body body 2DB is in contact with the back side of the front part of the crown portion of the cap, and is preferably curved as shown in FIG. 1, but the shape is not particularly limited.

As shown in FIG. 2, the procedure for using the cap ventilation aid 1 of the present invention is such that the front portion 2D of the main body is placed downward and the side of the main body attachment portion 2G is applied to the forehead. When 1 is inserted between the cap and the forehead, the main body 2 and the forehead portion form a forehead cavity 22, a main body front opening 2DD, and a main body rear opening 2EE. When the main body front portion 2D is set to a position not Shimawa enters the inside of the crown portion, the outside air that has been taken, et al or body before opening 2DD, after contact with the forehead forehead cavity 22, heating of the forehead, the sweat It is discharged from the main body rear opening 2EE located in the main body rear portion 2E together with the air in the forehead cavity 22 that has become high temperature and high humidity.
