In the illustrated embodiment, the communication hole 260 has a circular cross-section and a cylindrical shape with a height in the vertical direction.

The communication hole 260 may be opened or closed by the opening and closing member 400. When the opening and closing member 400 is rotated to close the communication hole 260, communication between the ventilation depression 210 and the receiving space 120 is blocked. When the opening and closing member 400 is rotated to open the communication hole 260, the ventilation depression 210 and the receiving space 120 may be in communication. A detailed description of this will be provided later.

A plurality of communication holes 260 may be formed. The plurality of communication holes 260 may be spaced apart from each other and communicate with the ventilation depression 210 and the receiving space 120, respectively, at different positions.

The cover member 300 partially covers the ventilation portion 200 and is coupled to the ventilation portion 200. That is, in a state in which the cover member 300 is moved to the front side, the cover member 300 covers the front side portion of the ventilation portion 200. In a state in which the cover member 300 is moved to the rear side, the cover member 300 covers the rear portion of the ventilation portion 200.

To this end, the cover member 300 may be formed to have an area smaller than the area of the ventilation portion 200, specifically, the area of the ventilation depression 210.

The cover member 300 is coupled to the opening and closing member 400. As will be described later, the opening and closing member 400 is rotatably coupled to the rotation support portion 230 of the ventilation portion 200 and can be rotated around the rotation support portion 230.

Hereinafter, the operation process of the cover member 300 and the opening and closing member 400 provided in the head protection equipment 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. 12 and 13.

Referring to FIG. 12, the cover member 300 and the opening and closing member 400 are moved to open the communication hole 260. In this state, the communication hole 260 communicates with the accommodation space 120 and the ventilation depression 210. At this time, the front side of the ventilation depression 210 is exposed by the movement of the cover member 300 and communicates with the outside.

Accordingly, in the state shown, the inside of the accommodation space 120 may leak out.

The movement process of the cover member 300 and the opening and closing member 400 to form the above state will be described in detail as follows.

first. The cover member 300 movably coupled to the ventilation portion 200 is moved to one side, to the rear side in the illustrated embodiment. The movement of the cover member 300 may be guided by the combination of the frame coupling portion 330 and the guide rib 250.

As the cover member 300 moves toward the rear, the opening and closing member 400 movably coupled to the cover member 300 moves. At this time, the engaging protrusion 420 of the opening and closing member 400 is movably received in the engaging space 323, and the engaging protrusion 420 includes the first extension portion 321 and the first extension portion 321 surrounding the engaging space 323. 2 It moves along the extension direction of the extension part 322.

The opening and closing member 400 is rotatably coupled to the ventilation portion 200 by the rotating shaft portion 430. Accordingly, one side of the opening and closing member 400, the front side in the illustrated embodiment, is restricted by the combination of the rotation shaft portion 430 and the rotation support portion 230.

As described above, the first extension part 321 and the second extension part 322 extend obliquely toward the lower rear side. Accordingly, as the cover member 300 moves toward the rear, the engaging protrusion 420 inserted into the engaging space 323 moves obliquely toward the upper front side. That is, the opening and closing member 400 rotates upward around the rotation shaft portion 430.

As a result, in the illustrated embodiment, as the cover member 300 moves to the rear side, the opening and closing member 400 may rotate counterclockwise to open the communication hole 260.

Referring to FIG. 13, the cover member 300 and the opening/closing member 400 are moved to close the communication hole 260. In this state, the communication hole 260 is closed by the opening and closing member 400 to block communication between the accommodation space 120 and the ventilation depression 210. At this time, the rear side of the ventilation depression 210 is exposed by the movement of the cover member 300.

That is, the front side of the ventilation depression 210 is covered by the cover member 300, and communication between the ventilation depression 210 and the outside is blocked. Accordingly, the inside air of the receiving space 120 does not leak out to the outside, and the outside air also does not flow into the receiving space 120.

first. The cover member 300 movably coupled to the ventilation portion 200 is moved to the other side, in the illustrated embodiment, to the front side. The movement of the cover member 300 may be guided by the combination of the frame coupling portion 330 and the guide rib 250.

As the cover member 300 moves toward the front, the opening and closing member 400 movably coupled to the cover member 300 moves. At this time, the engaging protrusion 420 of the opening and closing member 400 is movably received in the engaging space 323, and the engaging protrusion 420 includes the first extension portion 321 and the first extension portion 321 surrounding the engaging space 323. 2 It moves along the extension direction of the extension part 322.

As described above, the first extension part 321 and the second extension part 322 extend obliquely toward the lower rear side. Accordingly, as the cover member 300 moves toward the front, the engaging protrusion 420 inserted into the engaging space 323 moves obliquely toward the rear lower side. That is, the opening and closing member 400 rotates downward around the rotation shaft 430.

As a result, in the illustrated embodiment, as the cover member 300 moves toward the front, the opening and closing member 400 may rotate clockwise to close the communication hole 260.

At this time, the opening and closing boss part 450 provided in the opening and closing member 400 is inserted into the communication hole 260, and the outer circumference of the communication hole 260 is surrounded by the opening and closing depression 440 to seal the communication hole 260. As described above, can be performed more reliably.

The head protection equipment 10 according to the embodiment of the present invention described above includes a ventilation portion 200 communicating with the receiving space 120 and the outside. The ventilation portion 200 is provided with an opening and closing member 400 that is rotatable and configured to open or close the communication hole 260. The opening and closing member 400 is movably coupled to the cover member 300. The cover member 300 covers the ventilation unit 200 and the opening and closing member 400 accommodated in the ventilation unit 200 and is coupled to the ventilation unit 200.

Accordingly, the opening and closing member 400 can be rotated simply by moving the cover member 300 to open or close the communication hole 260. In one embodiment, the cover member 300 is moved in the same direction as another member for communication provided in the head protection equipment 10 and may be configured to allow or block communication between the receiving space 120 and the outside. .

Therefore, with a simple operation, the receiving space 120 and the outside can communicate and the inside of the receiving space 120 can leak out to the outside. In addition, the cover member 300 is operated in the same direction as the other members for the introduction of external air to allow or block communication between the receiving space 120 and the outside, thereby preventing confusion for the wearer.

Meanwhile, the cover member 300 covers the ventilation unit 200 and the opening and closing member 400 coupled to the ventilation unit 200, and is coupled to the ventilation unit 200. The side where the cover member 300 is exposed to the outside is formed to have a shape similar to the outer surface 110 of the external frame 100. Accordingly, the area where the ventilation portion 200, the cover member 300, and the opening/closing member 400 protrude to the outside of the external frame 100 can be minimized.

Accordingly, the air resistance generated by the provision of the ventilation portion 200, the cover member 300, and the opening and closing member 400 can be minimized, and degradation of driving performance can also be minimized. Furthermore, the outside of the head protection equipment 10 can be formed to be uniform as a whole, resulting in an attractive appearance.

Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention can add or change components within the scope of the same spirit. , deletion, addition, etc., other embodiments can be easily proposed, but this will also be said to be within the scope of the present invention.
