Section 30.

Next, in addition to the above-mentioned FIGS. 1 to 6 , the holding means will also be described with reference to FIGS. 7 to 11 . Fig. 7 is a front view showing the goggles of the embodiment. Fig. 8 is the A-A line sectional view of Fig. 7, which is the A-A line sectional view with the ventilation part closed. Fig. 9 is a perspective view showing the cut-off body of the goggles according to the embodiment along the line A-A with the ventilation part closed. Fig. 10 is the A-A line sectional view of Fig. 7, which is the A-A line sectional view with the air-permeable part opened. Fig. 11 is a perspective view showing the venting part of the truncated body after the goggles of the embodiment are cut along the line A-A.

As shown in Fig. 1 and Fig. 2, the holding means 40 is arranged on the outer peripheral portion 12 of the goggle lens 10, and when at least one air-permeable portion 30 can breathe, at least one air-permeable portion 30 can be engaged with the spectacle frame 20 , and used to maintain the localized elastic deformation of the mirror frame 20 .

As shown in FIG. 5 , the holding means 40 in the embodiment includes protrusions 41 . The protrusion 41 is protruded from the outer peripheral portion 12 of the goggle lens 10 toward the user's face in at least one of the air-permeable portions 30 .

Moreover, the protrusion 41 is arranged on the outer peripheral portion 12 of the goggle lens 10, and when at least one air-permeable portion 30 is able to breathe, it can be engaged with the frame 20 in at least one air-permeable portion 30, so as to keep a part of the frame 20 Sexual elastic deformation. If the engagement between the projection 41 and the frame 20 is released, the local elastic deformation of the frame 20 will be released, the gap 31 will be closed, and at least one ventilating portion 30 will return to be non-breathable.

Also, as shown in FIG. 5 , in the region where the air-permeable portion 30 is disposed at the rear end of the outer peripheral portion 12 of the goggle lens 10 , a shielding plate 42 is disposed that faces the protrusion 41 in the vertical direction. A gap corresponding to the thickness of the peripheral portion 22 of the mirror frame 20 shown in FIG. 6 is provided between the shielding plate 42 and the protrusion 41 .

As shown in Fig. 7, Fig. 8 and Fig. 9, when at least one air-permeable part 30 is closed and cannot breathe, in at least one air-permeable part 30, the peripheral part 22 of the frame 20 is clamped by the protrusion 41 and the covering plate 42 , and the airtightness of the air-permeable portion 30 in an air-tight state can be ensured.

Again, as shown in Fig. 10 and Fig. 11, when at least one air-permeable portion 30 is opened to allow ventilation, in at least one air-permeable portion 30, the peripheral portion 22 of the frame 20 is more positioned at the inside of the goggle lens 10 than the protrusions 41 side, and a gap 31 is formed between the goggle lens 10 and the frame 20 .

As described above with reference to FIGS. 1 to 11 , according to the goggles of the embodiment, the frame 20 is elastically deformable and keeps airtightly abutting against the outer peripheral portion 12 of the goggle lens 10 , at least one The air-permeable part 30 is arranged in the abutment region between the outer peripheral part 12 of the goggle lens 10 and the frame 20, and utilizes the local elastic deformation of the frame 20 to form a gap between the outer peripheral part 12 of the goggle lens 10 and the frame 20. The air-permeable gap 31 is thus able to breathe. When the local deformation is released, it returns to be unable to breathe. The retaining means 40 is arranged on the peripheral portion 12 of the goggle lens 10, and when at least one air-permeable portion 30 can When air-permeable, at least one air-permeable portion 30 can be engaged with the frame 20 to keep the local elastic deformation of the frame 20 .

Therefore, as long as a simple operation such as the operation of locally elastically deforming the spectacle frame 20 and the operation of releasing the local elastic deformation can be performed, it can be switched to: a ventilation state in which external air can be introduced into the inside of the goggles, and It prevents outside air from being introduced into the non-ventilated state or even the airtight state inside the goggles, and can be easily switched between the ventilated state and the non-ventilated state. In addition, the holding means 40 is used to hold the localized elastic deformation of the frame 20, thereby stably maintaining the ventilation state, making it comfortable to use in various environments and expanding its usage.

More specifically, as a switching means for switching between the ventilation state and the non-ventilation state, it is also conceivable to adopt, for example: providing air holes on the goggle lens 10 and providing a cover for opening and closing the air holes. However, if a cover for opening and closing the air hole is provided, not only the number of parts of the goggles will increase, but also a fixing means for fixing the cover in an open state and a closed state must be additionally provided, thereby causing the number of parts of the goggles to increase. for the increase.

In addition, the cover used to open and close the ventilation hole, for example, is in the state of protruding from the goggle body when it is opened. When the goggles are in use, the cover may collide with other items such as a protective helmet and the like and be damaged. Or something like an unexpected shutdown occurs, and it is considered that it cannot be stably switched into a ventilation state and a non-ventilation state.

According to the goggles of the embodiment, the gap 31 formed by the local elastic deformation of the frame 20 can be used to become air-permeable, and the local elastic deformation can be released to return to be non-breathable. Therefore, there is no need to use a cover. Not only can the number of parts be reduced, but also each part of the ventilating part 30 and the holding means 40 can be set so as not to protrude from the goggle body, so that damage and failure caused by collision with other components can be prevented, and Switching between the ventilation state and the non-ventilation state can be performed stably.

Especially as shown in Fig. 2, Fig. 10, Fig. 11, by making the local elastic deformation of the spectacle frame 20 which can make the air-permeable part 30 into the ventilating state deform toward the inner direction of the goggle lens 10, the The protrusion 41 used to form the holding means 40 is set so as not to protrude to the outside of the goggle lens 10. In use, it can prevent: the locally elastically deformed mirror frame 20, the protrusion 41 colliding with other components and causing damage, Or in the event that the ventilation state is unexpectedly switched to the non-ventilation state, switching between the ventilation state and the non-ventilation state can be performed more stably. In addition, since each part such as the air-permeable part 30 and the holding means 40 does not protrude to the outside, even when wearing a protective helmet, the gap 31 will not be blocked, and stable ventilation can be performed. .

1 to 11, according to the goggles of the embodiment, the holding means 40 includes a protrusion 41, and the protrusion 41 is formed on the outer peripheral portion 12 of the goggle lens 10, and is formed on at least one of the goggles. When the air-permeable part 30 is air-permeable, at least one air-permeable part 30 can be engaged with the spectacle frame 20 .

Therefore, as long as an external force is applied to the mirror frame 20 at the air-permeable part 30, and the peripheral portion 22 of the mirror frame 20 is hooked on the protrusion 41 or detached from the protrusion 41, the ventilation state and non-ventilation state can be performed. The switching of the ventilation state can be more simply switched to the ventilation state and the non-ventilation state. In addition, since the elastically deformable mirror frame 20 is hooked to the projection 41 to be in a ventilation state, even if vibration is applied from the outside, the state of the mirror frame 20 hooked to the projection 41 can be easily maintained, thereby stably Maintain a state of ventilation.

Also, as described with reference to FIGS. 1 to 11 , according to the goggles of the embodiment, at least one air-permeable portion 30 is provided at least one on each of the upper portion and the lower portion of the frame 20 . Therefore, the heated air inside the goggle lens 10 is discharged through the upper air-permeable part 30, and new air can be introduced into the inside of the goggle lens 10 through the lower part of the air-permeable part 30, which can prevent foreign matter from passing through. The air-permeable part 30 enters the interior, and can ventilate the lens in such a way as to prevent fogging of the lens.

1 to 11, according to the goggles of the embodiment, at least one air-permeable portion 30 is provided on the top of the frame 20, and the barrier wall portion 21 is the outer surface protruding from the top of the frame 20. , to prevent foreign matter from entering the at least one ventilating portion 30 from the direction of the user's face. Therefore, it is possible to prevent sweat from the forehead and the like from entering the inside of the goggle lens 10 , and it is possible to more reliably prevent lens fogging and the like from occurring.

The embodiments of the present invention have been described above with reference to the drawings ( FIGS. 1 to 11 ).
