[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a helmet for protecting a head to which a mask is detachably mounted in various fields such as baseball, softball, ice hockey, and the like. Specifically, the inner surface of a protective shell made of synthetic resin that covers the upper part of the head The present invention relates to improvement of a helmet in which a cushioning material is attached.
[0002]
[Prior art]
Conventionally, in a catcher helmet that is an example of a helmet, the front wall portion of the synthetic resin protective shell that covers the top of the head, the front half portion of the upper wall portion, and the front half portions of the left and right side wall portions are on the head. And a plurality of ventilation holes are formed in the inner surface of the protective shell.

The front wall and the chin of the wearer are distributed and received.
[0004]
However, since the front wall portion of the protective shell, the front half portion of the upper wall portion, and the front half portions of the left and right side wall portions are formed in a partially spherical curved surface along the head, the ball hits the upper portion of the catcher mask. In this case, since the catcher mask moves upward along the curved surface of the protective shell, it is necessary to pull down the catcher mask each time, and the next operation tends to be delayed. In addition, when the ball hits the center or lower side of the catcher mask, the catcher mask moves downward along the curved surface of the protective shell, so that the impact force tends to concentrate on the wearer's jaw. .
[0005]
Furthermore, a gap corresponding to the thickness of the cushioning material is formed between the inner periphery of the vent hole of the catcher mask and the scalp of the wearer, but the cushioning material is somewhat compressed when the protective shell is worn. Therefore, the substantial height of the gap is shortened, and as a result, not only the ventilation performance is deteriorated, but also when the butt hits and a crack occurs in the periphery of the vent hole, the crack is close to the wearer's scalp. There is.
