DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to detachable auxiliary sunglasses, and more particularly to detachable auxiliary sunglasses which are attached to the outside of ordinary glasses for correcting vision.

[0002]

2. Description of the Related Art Removable auxiliary sunglasses that are externally attached to ordinary glasses for correcting myopia and hyperopia are much cheaper than prescription sunglasses, so they can be used not only for outdoor activities such as fishing and driving. It is also widely used for daily life.

As shown in FIG. 1, the detachable auxiliary sunglasses are provided with an elastic bar-shaped pinching arm 2 on the back surface of the sunglass plate body 1, and the outer edge of the lens portion of the eyeglass frame to be worn by the pinching arm 2. 2 and a washing clip-like holding clip 4 urged by a coil spring 19 is attached to the bridge portion 3 at the center of the sunglass plate body 1 as shown in FIG. There is a type in which a lens portion of the eyeglass frame is held from behind by a holding arm 5 extending from the holding clip 4.

[0004]

Auxiliary sunglasses of the type shown in FIG. 1 have the advantage of being inexpensive to manufacture because of their simple structure, but because of their structure they cannot be flipped up. There is a disadvantage that it is difficult to temporarily stop using the auxiliary sunglasses when entering a dark place such as indoors or in a tunnel. In addition, there is a disadvantage that it takes time and effort to slide the holding arm 2 behind the lens of the eyeglass frame.

On the other hand, the one shown in FIG. 2 is fixed to the spectacle frame by the scissors-like holding clip 4, so that it can be easily attached to and detached from the spectacle frame. It has the advantage that it can be temporarily stopped when entering a dark place such as indoors or in a tunnel, but has many parts and costs However, there was a drawback that it took. In addition, since a part of the clip 4 protrudes in a conspicuous place above the bridge 3 in the center of the sunglass plate body 1, it is undeniable that a sense of incongruity occurs in appearance, and the appearance is refreshing as shown in FIG. I couldn't give that impression.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional detachable auxiliary sunglasses. The number of parts is small, it can be manufactured at low cost, and it can be easily attached to and detached from eyeglass frames. Another object of the present invention is to provide smart and easy-to-use detachable auxiliary sunglasses that do not give a sense of incongruity in appearance.

[0007]

The width of the bridge portion 9 of the spectacle frame 8 to be mounted is slightly shorter than the width of the bridge portion 9. The lower portion is inserted into the bridge portion 9 so that the bridge portion 9 is elastically mounted in the front-back direction. The bridge portion 3 at the center of the sunglass plate main body 1 is pivotally supported on the upper portion of the fixing block 7 made of a soft synthetic resin having the slit 10 sandwiched therebetween, and the sunglass plate main body 1 can be raised and lowered with respect to the eyeglass frame 8. By doing so, the above problem is to be solved.

[0008]

FIG. 3 is a perspective view of one embodiment of the detachable auxiliary sunglasses according to the present invention, and FIG. 4 is a perspective view of the same separately showing each part.

In FIG. 1, reference numeral 1 denotes a sunglass plate main body, and a pair of left and right sunglass plates 6 corresponding to both right and left eyes are connected by a bridge portion 3 provided at the center. The sunglass plate 6 is made of a translucent plastic plate or a plastic plate on which a metal film is deposited.

On the other hand, a fixing block 7 made of a soft synthetic resin has a width slightly smaller than the width of the bridge portion 9 of the glasses frame 8 to which the detachable auxiliary sunglasses are to be worn. The lower part is inserted into the bridge part 9 of the glasses frame 8, and the bridge part 9 is
Is formed to elastically hold the slit.

On the upper front surface of the fixing block 9, there is formed a slit 11 into which the bridge portion 3 of the sunglass plate body 1 is inserted and elastically clamped. In this embodiment, the fixing block 7 is made of an elastomer having a Shore D hardness of 50 to 90.

In this embodiment, the bridge portion 3 of the sunglass plate body 1 is inserted into the slit 11 on the upper front surface of the fixing block 7 as shown in FIG. In the state of being pinched, the lower slit 10 of the fixing block 7 is inserted into the bridge 9 of the spectacle frame 8, elastically pinched, and attached to the spectacle frame 8. In this state, the sunglass plate body 1 is supported by the fixing block 7 so as to be able to move up and down around the bridge 3 so that the sunglass plate body 1 can be flipped up as required.

Next, another embodiment of the auxiliary sunglasses according to the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a sunglass plate main body. In this embodiment, unlike the embodiment shown in FIGS. 3 and 4, the sunglass plate main body 1 is integrally formed of a single plastic plate, the center of which is constricted, and a bridge is provided. Part 3

On the other hand, reference numeral 7 denotes a fixing block made of a soft synthetic resin, and a lower portion thereof is formed with a slit 10 which is inserted into the bridge portion 9 of the eyeglass frame 8 and elastically sandwiches the same. The fixing block 7 is made of an elastomer having a Shore D hardness of 50 to 90.

The upper end of the bearing projection 1 has a narrow width.
2 are formed integrally with each other, and a long hole 13 is formed in the bearing projection piece 12 in the lateral direction (the same direction as the slit 10).
Are formed.

On the other hand, the bridge portion 3 of the sunglass plate body 1
The main body fixing piece 14 having a substantially U-shape and having the support arms 16 and 16 formed on both sides of the base 15 facing each other is attached to the base 1.
5 is fixed by inserting a fixing projection 17 provided in the through-hole 20 provided in the bridge portion 3.

The support arm 16 of the body fixing piece 4
The sunglass plate main body 1 is pivotally supported on the fixing block 7 by a pin 18 inserted into the elongated hole 13 so that the sunglass plate body 1 can be raised and lowered.

In this embodiment, similarly to the embodiment shown in FIGS. 3 and 4, the slit 10 of the fixing block 7 is formed.
Is inserted into the bridge portion 9 of the spectacle frame 8, and is elastically clamped from the front-rear direction, thereby mounting the spectacle frame 8. When the auxiliary sunglasses are detached from the spectacle frame 8, it is sufficient to apply a slight force to separate the fixing slit 10 from the spectacle frame 8. Further, since the sunglass plate body 1 is pivotally supported by the fixing block 7 so as to be able to move up and down, the user can easily flip the sunglass plate body 1 upward as needed while wearing the eyeglass frame 8, and temporarily You can stop using sunglasses.

[0019]

As described above, the detachable auxiliary sunglasses according to the present invention sandwich the eyeglass frame 8 by the elasticity of the fixing block 7, so that the detachable auxiliary sunglasses can be easily attached and detached, the number of parts is small, and the appearance is improved. It is very refreshing and can be worn easily without giving any discomfort to the surroundings. In addition, since it can be easily flipped upward as needed, it is suitable for wearing such as driving during which the brightness suddenly changes, and is very practical.
