Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to goggles used for skiing, driving a motorcycle, etc.

(Prior Art) Conventional goggles usually have only a dustproof lens without a diopter correction function attached to the frame.

(Problems to be Solved by the Invention) Therefore, when a person who requires diopter correction wears goggles, it is necessary to use contact lenses or glasses for diopter correction.

When a contact lens is used together, there is a problem in that the contact lens moves on the eyeball or falls off the eyeball in situations where tears are likely to occur, such as during strenuous exercise. In addition, when glasses are used together, there is a lack of safety in the event of a strong blow to the face, and fogging and dirt that obstruct vision occur not only on the inside of the dustproof lenses but also on both the front and back of the glasses lenses. There was a problem that it took a lot of time to remove the dirt.

(Means for solving the problem) The present invention was proposed to solve the above problem, and its gist is to attach a dustproof lens to a frame made of an elastic material and to adjust the diopter. A pair of lenses for correction are interconnected and integrated via a spacer so as to match the interpupillary distance of the user, and the integrated pair of lenses for diopter correction and the spacer are attached around it. A transparent and highly flexible film having folds or bends is attached to the frame at a slight distance from the inside of the dustproof lens, and the frame, the dustproof lens, and the diopter correction The goggles are characterized in that a sealed space is limited by a pair of lenses, a spacer, and a film.

(Function) Since the present invention has the above-mentioned configuration, by wearing these goggles, even people who require diopter correction can see objects clearly through the diopter correction lens without using contact lenses or glasses. Can be done.

In addition, even if you get hit on the face while wearing these goggles, the highly flexible film will easily bend at its folds or bends, so even if the dust-proof lenses are damaged, the diopter can be corrected. The pair of lenses and spacer will not be damaged.

Even if the film is bent, the pair of lenses for diopter correction and the spacer are integrated with each other, so they move as one, and therefore, the pair of lenses for diopter correction move as one. The spacing will not change and these optical axes will not shift.

(Example) An example of the present invention will be specifically described with reference to the drawings. In the drawing, 1 is a frame made of an elastic material such as rubber, and an elastic material 2 such as urethane foam is pasted on the inner surface of the frame 1.
By placing a band 3 made of rubber or the like connected to both ends of the head over the back of the head, the elastic material 2 is worn so as to be in close contact with the face. 4 is a dustproof lens,
After inserting the outer peripheral edge into a groove 5 cut in the frame 1, the frame 1 is attached to the frame 1 by engaging the clips 6 which are fixed at the top and bottom of the central part of the frame 1. A plurality of ventilation holes 8 are provided on the top and side surfaces of the frame 1 to ventilate the space inside the goggles. Reference numeral 9 denotes a pair of lenses for correcting diopter made of plastic or the like, which are connected to each other via a spacer 10 so as to match the interpupillary distance of the user. The lens 9 and spacer 10 are attached to the frame 1 at a predetermined distance inside the dust-proof lens 4 via a transparent, highly flexible, non-breathable film 11 made of vinyl, nylon, or the like. . This film 11
has folds or bent parts, and its inner periphery surrounds a pair of diopter correction lenses 9 and a spacer 10,
Further, the outer peripheral edges thereof are respectively bonded to the frame 1 using an adhesive. Thus, a sealed space 12 is formed between the dustproof lens 4 and the diopter correction lens 9 by the frame 1, the dustproof lens 4, the pair of diopter correction lenses 9, the spacer 10, and the film 11.

When wearing these goggles, objects can be clearly seen through the diopter correction lens 9, so there is no need to use contact lenses or glasses as in the past. Since a sealed space 12 is formed between the dustproof lens 4 and the diopter correction lens 9, the inner surface of the diopter correction lens 9 will not freeze even in extremely cold conditions, and the inside and outside temperatures will be reduced. Based on the increase in the difference, clouding occurring on the inner surface of the diopter correction lens 9 can be suppressed. Furthermore, the inner surface of the dust-proof lens 4 and the outer surface of the diopter correction lens 9 facing the sealed space 12 are free from fogging and dirt, so the outer surface of the dust-proof lens 4 and the outer surface of the diopter correction lens 9 are prevented from becoming cloudy or dirty. It is sufficient to remove the cloudiness and dirt generated on the inner surface of the lens 9, and therefore, the fogging and dirt can be easily removed.

Furthermore, the pair of lenses 9 for diopter correction are interconnected and integrated via a spacer 10 so as to match the interpupillary distance of the user, and the integrated pair of lenses 9 and spacer 10 are Since it is supported through a transparent and highly flexible film 11 that has folds or bends attached to its periphery, the visibility is not restricted by the film 11, and even if the goggles Film 1 that is highly flexible even if you hit your face while wearing it
1 easily bends at its folds or bends,
The pair of diopter correction lenses 9 and the spacer 10 are not damaged, and therefore, facial injuries can be suppressed and safety can be improved. Furthermore, even if the film 11 is bent, the pair of diopter correction lenses 9 and the spacer 1
Since the 0 moves as one, the distance between the pair of diopter correction lenses 9 does not change and the optical axis thereof does not shift, so visibility of things will not be deteriorated.

(Effect of the invention) In the goggles of the invention, a pair of lenses for diopter correction are arranged inside the dust-proof lens with a slight distance between them. You can see things clearly, so there is no need to use contact lenses or glasses as in the past.

Furthermore, a pair of lenses for diopter correction are connected and integrated via a spacer so as to match the interpupillary distance of the user, and these integrated lenses for diopter correction and the spacer are attached around them. Because it is attached to the frame via a transparent and highly flexible film with folds or bends, the film does not restrict your vision, and even if you hit your face hard while wearing goggles. Since the highly flexible film bends easily at its folds or bends, the pair of lenses and spacer for diopter correction will not be damaged, and even if the film is bent, the pair of lenses and spacer for diopter correction will not be damaged. Since the lens and spacer move together, there is no change in the distance between the pair of lenses for diopter correction and no deviation of the optical axis.

Furthermore, since the closed space is limited by the frame, dustproof lens, pair of lenses for diopter correction, spacer, and film, it is possible to suppress the occurrence of fogging and icing that impede visibility, and also prevent fogging and dirt from occurring. However, it can be easily removed.
