The layers 22, 23, 24 are made of the same type of elastically deformable foam material such as sponge or urethane, and can be bonded together well.

The inner and outer layers 22 and 23 each have a fine mesh so as to be easily deformed, and the inner layer has a fine mesh so that it can be bonded well to the flange 11. Further, since the outer layer 23 has fine mesh and is easily deformed, it feels good when touching the face.

The middle layer 24 is made coarse so that it does not easily deform. When the goggles 1 are worn, the inner and outer layers 22 and 23 are greatly deformed and become thinner, but the middle layer 24 is not deformed much.
Therefore, the foam pad 21 hits the face while maintaining its thickness and elasticity to a certain extent,
Therefore, the frame 3 does not feel like it is in direct contact with the face, and the goggles 1 have good contact with the face, and if the intermediate layer 24 is made of an open-cell foam material, the intermediate layer 24 will not deform much. Ventilation of the interior space 12 can also take place via the intermediate layer 24 .

Although the layers 22, 23, and 24 are shown to have approximately the same thickness, they may have different thicknesses.

Attach the connector 35 to the side insertion portion 33.

By the way, the side protection part 28 is used as an air outflow part and covers the exhaust port 18 from the outside.
It is constructed by integrally forming the guide portion 43, which mainly constitutes the side protection portion 28, the trapezoidal spacing portion 44, and the side insertion portion 33.

The guide portion 43 has a slightly curved shape toward the front, and its front end and upper and lower ends protruding rearward and diagonally inward are in contact with the side frame portion 6.

The spacing holding parts 44 are arranged in parallel on the inner surface of the guide part 43 at equal intervals in the vertical direction, projecting inwardly, and
It comes into contact with the outer surface of the lens holding part 9 of the side frame part 6, and
The protruding portion 45 protruding outward from the lens holding portion 9 comes into contact with the rear end, thereby preventing the protector 26 from shifting.

The spacer 44 cooperates with the upper and lower ends of the guide 43 to ensure a predetermined space between the guide 43 and the lens holder 9 of the side frame 6.

Air that communicates with the upper and lower exhaust ports 18 of the side frame section 6 is provided between the upper and lower ends of the guide section 43 and the interval retaining sections 44 adjacent to each end, and between the adjacent interval retaining sections 44. The rear end of the air outflow path 46 is an air outflow port 47 that opens rearward.

Further, the side insertion portion 33 projects from the guide portion 43 together with the spacing portion 44 .

According to the embodiment configured as described above, when the goggles 1 are worn and skiing or motocross competition, as shown in FIG. The outside airflow that has flowed to the rear side is further guided to the rear side by the guide portion 43 of the side protection portion 28.

At this time, since the pressure of the outside airflow is lower than the pressure of the internal space 12, the outside airflow causes the internal space 12 to
The air inside is sucked out rearward from the air outlet 47 via the exhaust port 18 and the air outlet path 46.

As a result of this air suction, as shown in FIG.
The outside air is sucked in from the lens 3, the internal space 12 is well ventilated, and the hot air generated from the face is well discharged, so that the lens 2 does not become foggy.

Further, the side protection part 28 covers the exhaust port 18 on the outside, and the outside airflow is not introduced into the side protection part 28, but the outside airflow is guided outside by the guide part 43. Furthermore, since the air outlet 47 that communicates with the exhaust port 18 has a rear opening shape, it is difficult for snow, mud, etc. to clog the inside of the guide part 43, the exhaust port 18, the air outlet 47, etc., and the internal space is reduced. 1
The exhaust function of the air in No. 2 is less likely to be inhibited.

Further, since the air intake port 13 is formed to penetrate in a substantially vertical direction and is covered from the outside with the foam sheet 14, the air intake port 13 will not be clogged with snow, mud, or the like.

(Effects of the Invention) As described in detail above, according to the present invention, the internal space of the goggles can be well ventilated, the lenses will not fog up, and the part for discharging the air from the internal space can be effectively ventilated. It is difficult for snow, mud, etc. to become clogged, and the function of discharging the air from the internal space is less likely to be inhibited.

Furthermore, since the protector is placed along the entire circumference of the frame, when the goggles are worn and ski competitions occur, the protector will absorb the impact when the goggles collide with an obstacle such as a pole. , the frame will not undergo local deformation,
Therefore, damage to the lenses is prevented, and deviation of the goggle wearing position is also prevented. Furthermore, even a large impact is supported by the protector in advance and is absorbed by the elastic frame while being dispersed throughout the protector, so it is safe without being strongly transmitted to the wearer's body. Furthermore, by making the side protection part of the protector into an air outflow part and the guide part forming an air outflow port there, the protector not only has the function of protecting the frame but also has the function of discharging the air from the internal space. , even though the protector is effective and the goggles are equipped with the above two functions,
The overall structure can be simplified and the appearance can also be improved.

The present invention has the above advantages and is of great practical benefit.
