Description

[Detailed explanation of the invention] Conventional flip-up glasses have a complicated flip-up mechanism, and each time the flip-up glasses are flipped up or down, the glasses vibrate, causing the joint screws in the lens frame to loosen or the hinges to loosen. There were some drawbacks such as the screws coming loose.

In order to eliminate such drawbacks, the present invention is designed to allow the secondary glasses, which correspond to flip-up glasses, to be rotated quietly.
Moreover, it is designed to be able to rotate over 180 degrees.

In the present invention, a plurality of short cylinders 3 are fitted tightly into an elastic cylinder 1 having a crack 2 in the axial direction so that the crack 2 is narrowed, and the fitted short cylinders 3 are used as glasses 4 and secondary glasses 5. This relates to eyeglasses with secondary glasses that can be tilted up and down, which are fixed to the upper edge or across the lens frame so that the secondary glasses can be lifted up and down, and when there are three cylinders 3 fitted into an elastic cylinder 1. As shown in FIG. 2, the cylinders 3, 3 at both ends are fixed to the upper edges of the left and right lens frames of the glasses, the middle cylinder 3 is fixed to the cross section 6 of the secondary glasses 5, and there are five cylinders 3. In this case, as shown in Fig. 3, the cylinders 3, 3 at both ends are fixed to the upper edge of the lens frame of the glasses 4, and the inner cylinders 3, 3 are fixed to the upper edge of the lens frame of the secondary glasses 5. 5 can be rotated by a minimum of 180 degrees with respect to the glasses 4.

As described above, according to the present invention, the short cylinders 3 at both ends of the short cylinder 3, which is tightly fitted into the elastic cylinder 1 having the crack 2 so that the crack is narrowed, are fixed to the upper edge of the lens frame of the eyeglasses. Then, fix the central short cylinder 3 to the cross section 6 of the secondary glasses 5, or fix the left and right cylinders 3, 3 to the upper edges of the left and right lens frames of the glasses 4, or fix the middle left and right short cylinders 3, 3 to the upper edges of the left and right lens frames of the glasses 4. Since they are fixed to the upper edges of the left and right lens frames of the secondary glasses 5, the secondary glasses 5 can be rotated and tilted up or down at any angle. Furthermore, since the secondary eyeglasses 5 are not flip-up type like conventional eyeglasses, the secondary eyeglasses can be quietly rotated to a predetermined angle. Since the rotation is quiet in this way, there is no vibration caused to the joint threads of the glasses or the hinge threads during rotation, which eliminates the drawbacks of conventional flip-up glasses, such as screws loosening or falling out. I was able to eliminate it. Also, after the rotation of the secondary glasses 5, each short cylinder 3
Due to the elasticity of the elastic cylinder 1, the secondary eyeglasses can be held securely and kept in a predetermined position.

Moreover, if the secondary glasses are rotated 180 degrees and held directly above the glasses 4, the secondary glasses will not rotate even when the user wears the glasses and exercises, and the secondary glasses can be kept in the raised position for a long time.

Incidentally, the cracks in the elastic cylinder 1 are provided in a straight line as shown in FIG. 4, or in a wave shape as shown in FIG.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; Fig. 1 is a plan view of glasses using three short cylinders, Fig. 2 is a front view when the secondary glasses are rotated by 90 degrees, and Fig. 3 is a diagram showing the short cylinders. A plan view when the secondary glasses are rotated 180 degrees using 5 glasses, Figure 4 is a perspective view of an elastic cylinder with a linear crack, Figure 5 is a perspective view of a short cylinder, and Figure 6 is a wavy crack. It is a partial perspective view of an elastic cylinder provided with. 1... Elastic cylinder, 2... Crack, 3... Short cylinder, 4... Glasses, 5... Secondary glasses, 6... Crossing.
