[Problem that the invention seeks to solve]

In this prior art, a partition wall 4A is interposed between the upper split seat 1 and the lower split seat 3, so that the upper split seat 1 and the lower split seat 3 do not directly contact each other, and a notch exists.
Then, in order to fit the entire circumference of the lens into the lens fitting groove, the upper split seat 1, the lower split seat 3, and the partition wall 4A have notches 1A, 3A, and 4G that match the lens fitting groove 2D.
When joining the glasses frame 2 and the eyepiece 4, the surface of the notch 4G of the partition wall 4A, the notch 1A of the upper split seat 1, and the cutout 3 of the lower split seat 3 are formed.
It must match side A. When fixing the upper split seat 1 and the partition wall 4A, the notches 1A, 4
G and fixing the lower split seat 3 to the partition wall 4A requires two face-to-face operations, one for the face-to-face alignment of the cutouts 4G and 3A, and the two-time face-to-face alignment work is complicated and troublesome. Therefore, if the face-to-face alignment work is not performed accurately, a step will occur in these notches 1A, 3A, and 4G, and an unnecessary and relatively large load will be applied to the end of the lens, which may cause damage to the lens. There is a point.

The present invention was made to solve the problems of the prior art.

[Means for solving problems]

Means for solving the above problems will be explained below using FIG. 1 corresponding to the embodiment. In this invention, an upper split seat 1 and a lower split seat 3 are formed in the cut portions 2A at both ends of the eyeglass frame 2, and the partition wall 4A of the eyepiece 4 is clamped between the upper split seat 1 and the lower split seat 3, thereby forming the eyeglass frame. 2 and 4, a protrusion 11 is formed on the inside of the lower surface 1D of the upper split seat 1, and a protrusion 31 is formed on the inside of the upper surface 3B of the lower split seat 3. Part 11, 3
1 in contact with each other.

[Effect]

With this configuration, face matching is required only when fixing the lower split seat 3 to the partition wall 4A, and there is no notch in the spectacle frame 2.
The entire circumference of the lens is held in the lens fitting groove of the spectacle frame 2.

〔Example〕

FIG. 1 is a diagram showing an embodiment of the present invention.
In FIG. 1, 11 and 31 are protrusions. The protrusion 11 is provided to protrude inside the lower surface 1D of the upper split seat 1. A notch 11A that coincides with the notch 1A of the upper split seat 1 is formed on the inner side surface of the protrusion 11. The protrusion 11 is formed by forming the upper split seat 1 with a thickness that includes the protrusion 11, and cutting off the outside thereof to form the lower surface 1D of the upper split seat 1. The protrusion 31 is provided to protrude inside the upper surface 3B of the lower split seat 3. A notch 31A that matches the notch 3A of the lower split seat 3 is formed on the inner side surface of the protrusion 31. The protrusion 31 is formed by forming the lower split seat 3 with a thickness that includes the protrusion 31, and cutting off the outside thereof to form the upper surface 3B of the lower split seat 3. The width of the partition wall 4A of the spacer 4 is shorter than the width of the upper wall 4B and the upper wall 4D, and the space 4 at the tip of the partition wall 4A
1, protrusions 11 and 31 are arranged.

The glasses frame 2 and the frame 4 are connected as follows. Open the space between the upper split seat 1 and the lower split seat 3,
Insert Wisdom 4 and move the upper split seat 1 to the upper split seat storage chamber 4C.
At the same time, the lower split seat 3 is stored in the lower split seat storage chamber 4E, and the partition wall 4A is sandwiched between the upper split seat 1 and the lower split seat 3. At this time, the projections 11 and 31 are in contact with each other. Next, the lower split seat 3 is opened, and the screw 5 is inserted through the through hole 4F and screwed into the screw hole 1C, thereby fixing the upper split seat 1 and the slot 4. In this process, since there is no notch in the partition wall 4A that coincides with the lens fitting groove 2D, there is no need to perform surface alignment work on the notch 11A. Next, with the lower split seat 3 open, insert a lens (not shown) into the lens fitting groove 2D, the notch 1A,
3A, 11A, and 31A, then close the lower split seat 3, insert the screw 6 into the hole 3C, and insert the notch 3 of the protrusion 31 into the notch 11A of the protrusion 11.
While aligning the surfaces of the screws 1A, screw them into the screw holes 5A of the screws 5 to fix the lower split seat 3 to the slot 4. Due to this fixation, the protrusions 11 and 31 come into contact with each other, and the lens fitting groove of the spectacle frame 2 including the lens fitting groove 2D is continuous without creating a step through the notch 11A or the like.

Even if the partition wall 4A is interposed between the upper split seat 1 and the lower split seat 3 of the glasses frame 2, the glasses frame 2 is continuous via the projections 11 and 31. Therefore, in the combination of the glasses frame 2 and the wisdom 4,
Since the face-to-face alignment work only needs to be done once, the glasses frame 2 can be easily connected to the eyepiece 4. Moreover, since the coupling is simple, the protrusions 11 and 31 can be accurately aligned, so that no step is created and the lens fitting grooves of the spectacle frame 2, including the lens fitting groove 2D, are continuous. Therefore, since the entire circumference of the lens can be held in the lens fitting groove of the spectacle frame 2, damage to the lens can be prevented.

In the above embodiment, the glasses frame 2 and the eyepiece 4 are connected by screws 5 and 6, but the screws are not limited to this, and any screws may be used as long as they can be connected detachably. .

〔Effect of the invention〕

As explained above, the present invention forms an upper split seat and a lower split seat in the cut portions at both ends of an eyeglass frame, and clamps the partition wall between the upper split seat and the lower split seat to attach the glasses. In the joint structure of the glasses frame and the eyeglasses that connect the frame and the eyepiece, a protrusion is formed on the inner side of the lower surface of the upper split seat, a protrusion is formed on the inner side of the upper surface of the lower split seat, and the protrusions are brought into contact with each other. This is how it was done. Therefore, when joining the eyeglass frame and the lens, only one face-to-face meeting is required, and the eyeglass frame is continuous without a cutout, and the entire circumference of the lens can be held in the lens fitting groove of the eyeglass frame. Therefore, according to the present invention, it is possible to easily connect the eyeglass frame to the eyepiece, and to prevent damage to the lenses.
