Abstract

PROBLEM TO BE SOLVED: To solve the following problems with the conventional spectacles; since the recent spectacles use plastic lenses in many cases; the lenses are liable to be flawed when the spectacles are dropped; particularly the conventional lens protective spectacles involve boring of the lenses of the two-point spectacles (rimless spectacles) with holes and therefore pressure is exerted on the lenses since temples are twisted when using lens protectors, the lenses are liable to crack from the point of screw holes or the designs of the spectacle frames are many and diversified and the dealing therewith by the conventional techniques is not possible depending upon the designs of the spectacle frames. SOLUTION: The spectacles with the lens protectors are provided with the lens protectors 1, 11 and 15 originally disposed at the portions of the front frame of the spectacles rotationally movably around the portions of the front frame as fulcra or slidingly movably in cylindrical or recessed shapes in such a manner that the lens protectors retract on the surfaces of the lenses 2, 12 and 10 or emerge thereon. The lens protectors 11 and 15 are made semi- automatically movable or rotationally or slidingly movable by using elastic members 8 and 14 (springs).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The eyeglasses.

[0002]

2. Description of the Related Art The glasses disclosed in U.S. Pat.
The design of the glasses is limited in order to rotate the anti-rotation at the mounting part of the front frame, and since the thing of the present invention is provided with its own lens protector than the glasses, other various kinds of It can correspond to the glasses of the design, the thing of the present invention has a stable and durable frame because the part of the vine is not anti-rotated. The glasses of 61-55097 are made by bending the temple part of the glasses. ,
The length of the temple is too high.For example, the modern length of a temple that is bent at the hinge is usually the full width of the front frame.
It ’s about 2.3cm long and the modern shape is unnatural
is there. The foldable half spectacles disclosed in the publication 07-10329 are foldable, and are limited to special half spectacles in which the width of the front frame of the spectacles is half the height of half glasses.

[0003]

In the case of two-point glasses (without a frame), a hole is formed in the lens, so the hole in the lens is weak against pressure and the lens is easily broken. In order to twist the glasses, the lens is likely to be cracked due to pressure around the lens, and there are various designs of the glasses frame, and depending on the design of the glasses frame, there are many that cannot be dealt with by the conventional technology.

[0004]

According to the first aspect of the present invention, a lens protector is provided on the front frame of the glasses, and when the lens protector is provided on the surface of the lens, the lens protects the lens. When using the glasses, the lens protector is in the way, so the screw 5 is used as a fulcrum to rotate in the direction of arrow K and attach to the temple side so that the glasses can be used. Elastic material 8 was used so that it could be temporarily fixed on it. Alternatively, it was temporarily fixed by pressing with temporary fixing tool 7, and a spring, which is elastic material 8, was provided on the front frame so that the lens protector could be easily rotated. Was. According to the second aspect, a part of the lens protector 11 independently provided on the front frame portion of the eyeglasses is engaged with the cylindrical or concave portion of the yoke portion 16 and temple 17 and slides in the direction of arrow F. By providing it as possible, when the lens protector 11 is on the surface of the lens, it plays the role of protecting the lens,
Since the lens protector becomes an obstacle when using the glasses, the part of the lens protector 8 shown in FIG. 4 is pulled in the direction of arrow F and moved to the position of the lens protector 8b, so that the lens protector 11 is moved from above the lens 12. The glasses shown in FIG. 8 in which retractable glasses can be used are provided with a lens protector joined to a portion of the eyepiece with screws 26 so that the lens protector can be moved in the direction of SS. In the third embodiment, the lens protector 20a is provided on the lens surface with a fulcrum fulcrum screw 26a.
And movably joined in the direction of S · S ′.

[0005]

FIG. 1 is a perspective view of a lens protector according to a first embodiment of the present invention. Is provided on the surface of the lens (providing the protective equipment 1 at a height where the lens surface does not hit the lens surface when the glasses fall), and when the frame of the glasses falls on the lens side or falls on the floor, the lens 2 Since the lens protector 1 provided on the surface of the lens protects the lens 2 and when the glasses are used, the lens protector 1 becomes an obstacle, so that the lens protector 2 is rotated around the screw 5 fulcrum from the surface. The elastic material 8 was provided so as to fit in the temple part as shown in FIG.
The lens protector 15 is provided to move semi-automatically using the principle of (spring) and cam. By removing the screws 5 and 19, the lens protectors 1 and 15 can be made detachable.

According to the second aspect of the present invention, referring to FIGS. 4, 5, 6, and 7, a part of a lens protector 11 uniquely provided on a front frame portion of eyeglasses is formed by a cylindrical part of a yoro part 16 and a temple 17 part.・
By being provided so as to be movable in the direction of arrow FF 'by engaging in a concave shape, the lens protector 11 serves as a lens protector when it is on the surface of the lens 12, and the lens protector 11 when using the glasses. The lens protector 11 is slid in the direction of arrow F so that it can be moved to the temple 17 part. 14 spring is provided, one end of the elastic member 14 spring is fixed to the lens protector 11, one end of the other elastic member 14 spring is fixed to the yoke portion of the frame, and the grip 8 of the lens protector is pulled to pull the lens protector. Slide to the position 8b,
By using the spectacles by temporarily fixing the above-mentioned thing by providing a portion that is difficult to slide, and removing the thing temporarily fixed at the position of the lens protector 8b when the lens protector 11 is necessary,
Glasses provided with the lens protector 8b slidably movable to the lens protector 8 by the elasticity of a spring. In the third embodiment, the lens protector 20a is provided on the lens surface by joining the yoke with the screw 26, and the lens protector 20a is provided so as to be movable in the direction of S and S 'around the screw 26.

[0007]

According to the present invention, a lens protector uniquely provided on a portion of the front frame of the glasses which is in contact with the surface of the lens is provided so that the lens protector is rotated along the arrow K with the screw 5 as a fulcrum so that the lens protector can be pulled out or retracted. Therefore, when the lens protector is provided on the surface of the lens, when the glasses are dropped, the lens protector on the lens acts as a lens protection, and when using the glasses, the lens protector becomes an obstacle. ,
The lens protector is rotated along the arrow K with the screw 5 as a fulcrum and attached to the temple, so that the lens protector is provided to fit naturally in the temple of the frame. 14 makes it possible to move semi-automatically and smoothly.

[0008] There are various types of eyeglass frame designs, and there are many eyeglass frame designs that cannot be dealt with by conventional techniques. A lens protector uniquely provided on the front frame of the glasses can be provided on the center of the surface of the lens, thereby increasing the probability of protecting the lens. The lens protector may be provided detachably.
