Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a baseball helmet with improved safety, durability and a feeling of wearing a hat.

[0002]

[Prior art]

 Conventionally, various types of baseball helmets are known, but there are batter helmets and catcher helmets in baseball helmets.If you explain about batter helmets, it consists of a cap body and interior materials. The cap body is provided with an eaves, an ear flap, an ear hole, and a ventilation hole. The conventional cap has a hemispherical shape, and the eaves have a rounded shape when viewed from the front and the top. In addition, the line connecting from the side of the eaves to the ear flap is generally connected at an acute angle at the temple part, and the shape of the ear hole is a perfect circle or an elliptical shape close to a perfect circle. As for the interior material, it is common that the interior material has almost the same shape as the cap body and is adhered to the inside of the cap body in a state of being in close contact.

[0003]

[Problems to be solved by the device]

 In conventional helmets for batters, the shape of the cap body is close to the shape of a hemisphere, so it is difficult to feel the depth of fogging, and therefore the feeling of wearing a hat is poor. Moreover, since the cap body and the interior material are adhered in close contact with each other, it cannot be said that the cap body has sufficient impact resistance when subjected to a strong impact.

Further, the line from the side of the eaves to the ear flap is connected at an acute angle at the temple, so it is weak against impact, and the ball hits the ear flap, or Helmet falls off the batter's head and hits the ground. Often, the impact dropped on the head caused a crack from the temple part. Furthermore, since the shape of the ear hole provided on the ear flap is a perfect circle or an elliptical shape close to a perfect circle, when the ball hits the ear hole, the ball blocks the ear hole and the impact on the ear is great. In the worst case, it could cause eardrum damage. On the other hand, in terms of breathability, the conventional baseball helmet has only five small-diameter vent holes in the vicinity of the crown, which is not sufficient. The present invention has been devised to solve the above-mentioned drawbacks of the conventional technology, and provides a helmet that is rich in impact resistance, durability, safety, and has a comfortable feeling of wearing a hat. The purpose is to do.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the baseball helmet of the present invention makes the rising angle of the temporal curve of the cap close to vertical, and the temporal curved surface and the forehead curved surface form the crown curved surface and the ridge line. -Shaped ribs are formed, and a space is provided between the substantially hemispherical-shaped interior material and the back surface of the ridge-shaped ribs of the cap body. The line is formed by a smooth curved line, the ear hole formed in the ear flap has a substantially oval shape, and the vent hole is formed in the top surface of the cap body. The ventilation hole formed inside the groove formed in the interior material mounted inside is connected to the ventilation hole formed in the cap body.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 3, the cap body 1 injection-molded from polycarbonate resin has a rise in the temporal curved surface B and the frontal curved surface C as compared with the conventional baseball helmet shown in FIG. The angles are formed so as to be nearly vertical, and each curved surface is formed with a crowned curved surface A and a rib 3 having a ridge line shape. The rib 3 may represent a clear ridgeline or may be a gentle ridgeline.

As shown in FIGS. 1 and 2, the eaves side portion 8 is linearly configured as compared with the conventional eaves shown in FIG. 6, and the eaves 2 itself is relatively flat as compared with the conventional eaves. Is formed into. Although not shown, it is preferable that the back surface of the eaves 2 is embossed so as to have the effect of preventing reflection and preventing slippage.

Further, as shown in FIG. 7, in the conventional baseball helmet, the line continuing from the eaves side portion 8 to the ear flap 5 was connected at an acute angle at the temple portion 7, so that stress concentrates on the acute angle portion. However, the helmet of the present invention has a drawback that cracks tend to occur from the temple part 7, but as shown in FIG. 1, the line from the eaves side part 8 to the ear flaps 5 has a smooth curve in the temple part 7. It has a shape that disperses the response. Although not shown, it is possible to further reinforce by making the temple 7 and its vicinity thicker.

As shown in FIG. 7, the ear hole 4 formed in the ear flap 5 of the conventional baseball helmet is formed in a perfect circle or an elliptical shape close to a perfect circle. In the helmet of the present invention, as shown in FIG. 1, the ear hole 4 formed in the ear flap 5 is formed in an oval shape having a horizontal major axis. Further, an ear pad 12 is provided around the outer edge of the ear flap 5.

As shown in FIGS. 1, 2, and 3, the top curved surface A of the baseball helmet of the present invention is provided with an arbitrary number of relatively large rectangular or circular ventilation holes 6a. . As shown in FIG. 4, these vent holes 6a are formed so as to correspond in number and shape to the vent holes 6b formed inside the groove 10 formed in the interior material 9. The interior material 9 is made of a material such as polystyrene foam that is lightweight and has appropriate elasticity, and is integrally molded. A head band 11 made of a soft material such as sponge is provided around the opening and worn. You may improve the feeling of hat. Further, as shown in FIGS. 5 and 6, the outer shape of the interior material 9 is substantially hemispherical, and when the interior material 9 is mounted inside the cap body 1, a space portion D is formed on the back surface of the ridge line-shaped rib 3. Is formed to occur.

[0011]

[Effect of device]

 With the above-described structure, when the baseball helmet of the present invention is worn, the cap body 1 has the ridge-shaped ribs 3 and the space D is formed between the interior body 9 and the back surface thereof. As shown in FIG. 6, the impact from the outside is effectively dispersed, the impact resistance is improved, and even if the cap body 1 is destroyed due to a strong impact on the rib 3 portion, the above-mentioned space is not provided. Has the effect of cushioning the impact. The side surface B and the front surface C of the cap body 1 are formed such that the rising angles thereof are nearly vertical, so that the depth of fogging can be felt. The eaves lateral portion 8 is formed more linearly than the conventional one, and the eaves 2 itself is also formed relatively flat, so that a wide field of view is ensured and the eaves lateral portion is provided when standing in the batter box. It is difficult for part 8 to enter the field of view.

Further, in the temple part 7 of the hat body 1, since the line continuing from the eaves side part 8 to the ear flap 5 is formed by a smooth curve, when the ear flap 5 is impacted, The stress is not concentrated on the temple part 7, and the effect of preventing the occurrence of cracks is exerted. Furthermore, by forming the vicinity of the temple portion 7 to be thick, it is possible to further prevent the generation of cracks. Since the ear flaps 5 formed in the ear flaps 5 have a substantially oval shape, even if the baseball ball hits the ear holes at all angles and at all speeds, all the ear holes 4 are always closed. Since it is formed so as to allow air to escape without being lost, it has the effect of reducing the burden on the ears.

Further, a plurality of relatively large vent holes 6a are formed in the crown top surface A of the cap body 1, and the interior material 9 mounted inside the cap body 1 includes the cap body A plurality of vent holes 6b connected to one vent hole 6a are provided, and the vent holes 6b are connected by a groove 10 provided inside the interior material 9 that contacts the human head. Therefore, the outside air entering from the ventilation hole 6a formed in the cap body 1 is guided to the inside through the ventilation hole 6b of the interior material 9 connected to the ventilation hole 6a, and passes through the groove provided inside. Spread throughout. Further, the hot air accumulated inside the helmet is guided to the ventilation holes 6b, 6a through the groove 10 and is effectively exhausted, so that the inside of the helmet is kept comfortable.
