Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to flip-up glasses in which another frame is attached to a front portion of the glasses, and the frame can be flipped up as needed.

[0002]

[Prior art]

 The flip-up glasses are glasses configured so that another frame attached to the front of the front frame can be opened and closed up and down. This type of glasses is well known in the art, and for example, a format in which sunglasses are attached to myopia glasses and used as a flip-up type, or reading glasses are used as a flip-up type is often used. That is, it is an eyeglass frame having a double front frame structure, and the front (front) frame is openable.

FIG. 17 shows an example of a conventional apparatus for flipping up spectacles that has been used as a flip-up apparatus. As is clear from the figure, the spectacles can be flipped up by a flip-up frame (a) and a front frame (b) of the spectacles with a vine attached, and a concave joint (c) and a convex joint ( D) is attached and connected via pin (e).

FIG. 18 is an enlarged cross-sectional view of the joint portion. The convex joint portion (d) is fitted into the concave joint portion (c) and is fixed to the opening bottom surface (f) of the concave joint portion (c). The leaf spring (G) is in contact with the butting surface (H) of the convex joint (D) while applying a spring force. Therefore, when the flip-up frame (a) is flipped up, the leaf spring (g) is deformed and pushed to the bottom side, and when it comes into contact with the upper surface (i) of the convex joint (d), the original spring is restored. Restore to shape. Needless to say, a predetermined spring force acts even when the frame comes into contact with the upper surface, so that the flip-up frame (a) does not close naturally and maintains a state of being flipped up.

[0005] By the way, the flip-up frame that is flipped up is attached via the above-mentioned joint, and cannot be removed as needed. For example, in the case of glasses in which reading glasses are flip-up type, when driving a car or walking on a road, the reading glasses are unnecessary, and the conventional flip-up glasses must always be lifted and opened. Therefore, the flip-up frame is protruding to the front, and not only is the glasses heavy, but also the center of gravity moves further forward, causing a positional shift of the glasses.

[0006]

[Problems to be solved by the invention]

 As described above, the conventional flip-up glasses have the above-described problems. The problem that the present invention seeks to solve is this problem, in which the flip-up frame is provided not only so that it can be flipped up, but also can be easily flipped up if necessary.

[0007]

[Means for solving the problem]

 The flip-up glasses of the present invention have a structure that not only allows the flip-up frame to be flipped up, but also functions as a front-hanging frame that can be removed from the glasses. The flip-up frame is then fitted with a fixture on the back, which is attached to the front frame of the glasses. Moreover, it can be attached to and detached from the front frame, and can be removed if the flip-up frame is not required.

By the way, there are various specific structures for mounting the flip-up frame to the front frame. (1) A fixing tool having a fitting groove formed in the front frame is provided, and the ends of the arms extending to both sides of the mounting tool are provided. The arm is fitted in the fitting groove and the arm is prevented from rotating. (2) A hole is formed in the bridge, bar, or the like of the front frame, and the lower ends of the legs provided on the fixture can be fitted and attached to the hole. (3) The fixture may be provided with a clamping portion, and the bridge may be fitted to the clamping portion. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0028]

[Effect of the invention]

 The flip-up glasses of the present invention not only allow the flip-up frame attached to the front frame to be easily flipped up and closed, but also remove the flip-up frame from the front frame. For example, when a sunglass is used as a flip-up frame for myopic glasses and the sunglasses are not needed for a long time, they can be removed without flipping. Therefore, the glasses become lighter as a whole, and especially the glasses in the flipped-up state shift the center of gravity, causing the glasses to shift.However, in the present invention, there is no such a shift in the glasses and the fatigue is further reduced. .
