DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baseball helmet (hereinafter abbreviated as "helmet") improved to quickly evaporate sweat to dry the inside of the helmet and keep the head comfortable.

[0002]

2. Description of the Related Art Conventionally, a baseball helmet includes a batter's helmet and a catcher's helmet. If the catcher's helmet is described as an example, it is necessary for the batter to protect his head from a swinging bat. A helmet body having strength and provided with ventilation holes for ensuring ventilation, and a substantially air-permeable interior material adhered to substantially the entire inner surface of the helmet body; In general, an impact buffer liner is attached to an arbitrary portion inside the helmet body in order to reduce an impact generated on the head when the vehicle hits the helmet.

[0003] The interior material will be described in more detail. A woven fabric obtained by using an arbitrary synthetic fiber such as a polyester fiber as a material and knitting it into a knit or mesh shape is used. The woven fabric is a woven fabric woven with fibers of a general shape having a circular cross section, and the number of woven fabrics per volume is set so as not to block the ventilation from the ventilation holes provided in the helmet body. Less
A large gap or many gaps are provided to ensure air permeability.

[0004]

By the way, when a player wears a helmet and plays baseball, the temperature inside the helmet rises to a high temperature and sweats from the head. In particular, the catcher wears the helmet much longer than the batter and has a greater amount of exercise than the other positions, so the inside of the helmet tends to become hot and sweat more easily from the head.

However, a conventional baseball helmet,
Especially for helmets for catchers, although the temperature inside the helmet can be lowered by ventilation from the ventilation holes, if a large amount of sweat is sweated from the head, the sweat will cool down as it adheres to or penetrates the interior material, There is a problem that a sticky feel or a heavy and cold feel remains, which makes the person feel uncomfortable or sick.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and has been improved so that sweat quickly evaporates to dry the inside of the helmet and keep the head comfortable. It is intended to provide a helmet for use.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and the invention of claim 1 is a baseball helmet in which an interior material is adhered inside a helmet body. The base material helmet is characterized in that the interior material is a woven fabric woven with a fiber having a constant cross-sectional shape composed of a small-diameter core and three or more protrusions formed on the outer periphery thereof. .

According to a second aspect of the present invention, there is provided a baseball helmet having an interior material adhered inside a helmet body,
The interior material is formed by bonding a sponge to a fabric woven from fibers having a constant cross-sectional shape, which is composed of a small-diameter core and three or more protrusions formed on the outer periphery thereof. A baseball helmet characterized by being adhered to a baseball helmet.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a baseball helmet 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA, FIG. 3 is a bottom view showing the same baseball helmet 1, FIG. FIG. 2 is a cross-sectional view of a fiber constituting a fabric used as an interior material of the baseball helmet 1. FIGS. 5 and 6 are cross-sectional views of fibers constituting a fabric used as an interior material of a baseball helmet of another embodiment.

As shown in FIGS. 1 to 3, the baseball helmet 1 has a strength necessary for protecting a head from a bat swung by a batter, and a ventilation hole 3 for securing ventilation. The helmet body 2 provided and the interior material 4 having high air permeability are adhered to substantially the entire inner surface of the helmet body 2, and further, an impact generated on the head when the bat collides with the helmet body 2 is provided. In order to relieve the impact, a shock-absorbing liner 5 is adhered to the inside of the helmet body 2 at the portions corresponding to the frontal, lateral and occipital regions.

In this embodiment, the helmet body 2 is made of polycarbonate resin, ABS resin, AES resin,
Alternatively, an injection molded article of a thermoplastic resin having excellent impact resistance, such as an alloy resin thereof, can be used. As the impact buffer liner 5, a thermoformed product obtained by laminating a urethane sheet, a urethane sponge, and a urethane sheet in a mold, closing the mold, and heating and compressing the same can be used. And, as the interior material 4, a woven fabric composed of a small-diameter core and three or more protrusions formed on the outer periphery thereof and having a constant cross-sectional shape can be used.

The woven fabric woven from the fibers having such a cross-sectional shape has a capillary action which sucks up moisture by a groove between the tangs and guides the water to the surface of the woven fabric, and has a circular cross-section. The surface area is larger than that of a fiber having a general shape, so that the moisture can be quickly evaporated. Therefore, even if sweat sweats from the head and sweat adheres to or penetrates the interior material, the sweat can quickly evaporate and the inside of the helmet can be dried, and the head can always be kept comfortable with a smooth feel. It becomes a baseball helmet.

The woven fabric used for the interior material 4 has a groove having a capillary action and is woven with fibers having a larger surface area than fibers of a general shape having a circular cross section. As shown in FIG. 4, for example, as shown in FIG. 4, a “UFO (unconfirmed flying object)” composed of a small-diameter core 6 and four protrusions 7 formed on the outer periphery thereof is formed. A woven fabric woven with fibers 8 having a uniform cross-sectional shape (for example, “Coolmax” (trade name, manufactured by DuPont) —a woven fabric obtained by knitting polyester fibers having the above-described cross-sectional shape into a knitted fabric— 5)
As shown in FIG. 5, a woven fabric woven with fibers 8 having a constant cross-sectional shape such as a "star", comprising a small-diameter core 6 and five protrusions 7 formed on the outer periphery thereof, As shown in FIG. 6, a woven fabric woven with fibers 8 having a constant cross-sectional shape such as a “propeller”, which is composed of a small-diameter core 6 and three protrusions 7 formed on the outer periphery thereof, It can be a woven fabric woven with fibers of various shapes.

A fiber having a constant cross-sectional shape composed of a small-diameter core and one or two protrusions formed on the outer periphery thereof has a general cross-sectional shape of a circular fiber. In comparison, the surface area is not so large, and the water cannot be evaporated quickly, which is not preferable.

The interior material 4 is not shown, but
A structure in which a sponge made of a soft material such as a plastic foam is attached to a woven fabric woven with fibers having a constant cross-sectional shape composed of a small-diameter core and three or more protrusions formed on the outer periphery thereof. Alternatively, the sponge side may be attached to the helmet body 2. In this case, it is possible to provide a baseball helmet that quickly evaporates sweat, dries the inside of the helmet, keeps the head comfortable, and provides cushioning.

The interior material 4 is adhered to substantially the entire inner surface of the helmet body 2 in the above embodiment.
Partial implementation is also possible, such as using the interior material 4 near an arbitrary portion on the inner surface of the helmet body 2, for example, near the top of the head with a large amount of sweat, and using a conventional interior material for other portions.

[0017]

As described above, the baseball helmet according to the present invention is a baseball helmet in which an interior material is adhered to the inside of the helmet main body. Since it is a baseball helmet characterized by being a woven fabric woven with fibers having a constant cross-sectional shape composed of more than one protruding protrusion, the sweat is quickly evaporated and the inside of the helmet is dried,
The head can be kept comfortable.

Further, in a baseball helmet in which an interior material is adhered to the inside of the helmet body, the interior material is a fixed core composed of a small-diameter center core and three or more protruding protrusions formed on the outer periphery thereof. A baseball helmet characterized by a sponge stuck to a woven fabric woven with fibers having a cross-sectional shape, and the sponge side is stuck to the helmet body, allowing sweat to evaporate quickly and drying the inside of the helmet This makes it possible to keep the head comfortable and provide cushioning.
