Abstract

PROBLEM TO BE SOLVED: To obtain dustproof spectacles which allow the use of a dustproof section in an open state in spite of the degradation in the stability of the dustproof section. SOLUTION: When temples 4 are opened in using the housed dustproof spectacles, the dustproof section 2 held bent inward by means of detaining parts 2a for loosely enclosing the temples 4 can be opened to the original state. Even if the stability of the dustproof section 2 is degraded by resting the spectacles in the folded state for a long period of time, the dustproof section 2 is pulled back by the detaining parts 2a and is restored to the usable state by the detaining parts 2a when the temples 4 are opened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to dustproof glasses for protecting eyes from dust, splashes, wind pressure, and the like.

[0002]

2. Description of the Related Art A conventional dustproof spectacle of this type includes a surrounding spectacle section located in front of an eye, a flexible dustproof section attached to the spectacle section, and a rubber band attached to a head. In many cases.

[0003] When wearing the dust-proof glasses, the band is stretched while the spectacles section is pressed against the face and fitted to the head.

[0004]

However, in this conventional dustproof spectacle, the band is stretched while pressing the spectacle portion against the face as described above, and the band is fitted to the head, so that there is a problem that the wearing is not easy. Dust-proof glasses are often worn at the same time as the head protection helmet.If you put on the helmet before putting on the helmet, the dust-proof glasses may come into contact with the helmet and shift. Ear straps are in the way, so if you do not take off your helmet, you will not be able to remove the dust-proof glasses.

Conversely, when the helmet is worn first,
Like fumbling a helmet larger than the head,
The band of dust-proof glasses must be brought to the back of the head and hanged, which is troublesome. In addition, when the dust-proof glasses become unnecessary after insertion, it is common to pull the glasses part forward of the helmet and shift it, and fix it near the front of the helmet by the contraction force of the band. However, there is a risk that the eyeglass part slips toward the top part due to some beat, which is both an obstacle and a danger.

In order to prevent this displacement, a method is also known in which a pair of right and left fixing brackets for an eyeglass band are attached to a helmet to fix the band. In this case, the brackets protrude outward from the helmet. Because it is in a form, for example, when passing through a narrow passage at the site during construction work, there is a risk that the bracket may be caught and it is dangerous, and the cost and weight of the bracket are added to the helmet Become.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a vine-type dust-proof glasses that can be easily mounted.

[0008]

According to the present invention, there is provided a dustproof spectacle for protecting an eye by being attached to a face, wherein the spectacle is made of a transparent material located in front of the eye. And a dustproof part attached to the periphery of the eyeglass part and made of a flexible material, and an ear hook part attached to the eyeglass part, and a part of the ear hook part is locked to the dustproof part. For providing a locking portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiment. FIG. 1 is a perspective view of the dust-proof glasses according to the present embodiment as viewed from the front. The dustproof glasses are bilaterally symmetrical, and are provided with spectacles 1 made of a transparent synthetic resin positioned in front of the wearer's eyes, and a dustproof part made of a synthetic resin having flexibility for protecting the eyes from dust and the like. 2, an ear-hook mounting portion 3, and a vine-shaped ear-hook portion 4 used for ordinary eyeglasses for mounting the dust-proof glasses on the face.

The dust-proof part 2 is joined to the periphery of the spectacle part 1. The dust-proof part 2 is made of a goggle-type member having more flexibility than the spectacle part 1. Protect eyes. Further, on the left and right side surfaces of the spectacles portion 1, ear hook mounting portions 3 made of synthetic resin and having the same strength as the spectacles portion 1 are provided integrally with the spectacles portion 1.

Further, the base portions 4a of the vine-shaped ear hook portions 4 are mounted on the left and right ear hook mounting portions 3 via shafts 5 so as to be rotatable within a certain angle range. The base 4a is provided with a guide portion 4b having a U-shaped cross section for guiding along the edge of the ear hook portion 4. The ear hook portion 4 further includes a cylindrical portion 4d connected to a base portion 4a via a hinge portion 4c.
And an earpiece 4e that can be fitted to the cylindrical part 4d. The cylindrical portion 4d is hinged to the base 4a.
The earpiece 4e is made to be freely foldable inward, and the earpiece 4e is made expandable and contractible in the front-rear direction by fitting into the cylindrical part 4d.

On the side surface of the dustproof portion 2, a band-like locking portion 2a for loosely locking the cylindrical portion 4d is provided.
A restricting portion 2b composed of a pair of protrusions for restricting the movement of the cylindrical portion 4d with some margin is formed behind the side surface of the cylindrical portion 4d, and the cylindrical portion 4d is inserted between the protrusions. Also, small holes 4f are provided at the ends of the earpieces 4e, respectively, so that strings or the like for hanging from the neck when dustproof glasses are removed can be attached.

The spectacles 1 are provided with a coating for preventing fogging, for example, and a ventilation hole 6 through which air flows but does not pass dust, splashes, etc., is appropriately formed below the dustproof portion 2. . The dustproof part 2 is preferably made of a transparent material so that the surroundings can be seen to some extent.

When using the dustproof spectacles, the user can easily wear the dustproof spectacles by using the ear hooks 4 irrespective of whether a helmet is worn or not. When the length of the ear hook portion 4 is adjusted and the ear hook portion 4 is hooked on the ear, the dustproof portion 2 is closely attached to the periphery of the eye, and the wearer's eye can be protected from wind pressure, dust, splash, and the like.

In this case, the base 4
a is rotatably mounted in a certain angle range, can be finely adjusted according to the shape of the wearer's head, and can adapt the dustproof part 2 to anyone's face. However, excessive rotation is regulated by the regulation part 2b of the dustproof part 2, and the guide part 4b can prevent the base part 4a from expanding with respect to the ear hook part 3.

When the dust-proof glasses are stored in a pocket or the like, as shown in the perspective view of FIG.
e is pushed into the cylindrical portion 4d to make the ear hook portion 4 the minimum length, and then folded inward by the hinge portion 4c. Since the dustproof portion 2 is made of a flexible material, the edges of the dustproof portion 2 are also bent inward as the ear hooks 4 are bent inward.

On the other hand, when the dust-proof glasses are taken out of a pocket or the like and worn, the earpiece 4e is pulled out from the cylindrical part 4d, and when the earhook part 4 is opened, the locking part 2a for loosely wrapping the earhook part 4 is opened. The dustproof part 2 that has been bent inward can be opened to its original state, and the dustproof part 2 can be in close contact with the face. Even if the resilience of the dust-proof portion 2 is reduced due to being left in the folded state for a long time, the locking portion 2a
The dustproof part 2 is pulled back by the locking part 2a when the ear hook part 4 is opened, and is restored to a usable state.

The ear hook 4 may be directly attached to the spectacles 1. In addition, the fact that the ear hook portion 4 is extendable and contractable and the presence of the restricting portion 2b are not essential problems of the present invention, and do not have to have such a function.

[0019]

As described above, in the dustproof glasses according to the present invention, even if the resilience of the dustproof portion is reduced by folding, the ear hook portion is expanded, so that the dustproof portion can be used through the locking portion. Can be restored.
