The armor 7 and the arm 8 are connected via an armor part 9 provided on the armor 7, and FIG. 4 shows a state where the armor 7 and the arm 8 are connected. I have. The armor 7 has a linear shape and is provided at one end with a hole for screwing the lens 2 to the lens 2. The central portion 7a of the armor 7 extends in the rear direction of the lens 2, and after bending the other end portion downward, is again folded in the direction of the lens 2 to form a folded portion 7b. It is formed on the portion 7c.

On the other hand, an armor part 9 for connecting between the armor 7 and the arm 8 is formed as shown in FIGS. That is, a pair of upper and lower flange portions 10 and 10 are integrally connected by a connecting portion 11 including a prism portion 11a and a cylindrical portion 11b. A central hole 12 passing through the upper and lower flange portions 10 and 10 and the connecting portion 11 It is provided at the center of the parts 10, 10.
The height of the prism 11a is substantially the same as the thickness of the linear armor 7, and the column 11b is
And the thickness is substantially the same. Therefore, armor part 9
The armor 7 and the arm 8 can be located between the two flange portions 10 and 10.

Next, assembling of the above will be described. First, the central portion 7a of the linear armor 7 having a hole for fixing the screw 4 to the lens 2 at one end is positioned on the prism 11a of the armor part 9. Therefore, the central part 7 of the armor 7
“a” comes into surface contact with one side of the prism 11a. Then, the folded back end is positioned below the flange 10 on the side where the column 11b is located, and then the upright 7c.

As described above, the central part 7 a of the armor 7 is positioned with respect to one side of the prism 11 a of the armor part 9. When the armor part 9 is rotated, an acting force is generated so as to return to the initial state, that is, the state of line contact or surface contact with one side. .

Next, the armor part 9 and the arm 8 are connected, and the end of the arm 8 is fixed to the cylindrical part 11b in a tightly wound state by using the column part 11b of the armor part 9. in this case,
The position of the arm 8 is positioned inside the folded portion 7b of the armor 7, that is, on the user side, and the arm 8 is fastened and fixed. As a result, the arm 8 is integrated with the armor part 9, and is rotatable about the center hole 12 of the armor part 9, that is, the upright portion 7 c of the armor 7.

Since the thickness of the arm 8 and the height of the cylindrical portion 11b of the armor part 9 are substantially the same, the central portion 7 of the arm 8 and the armor 7
There is no risk of rubbing with a.

Therefore, by assembling as described above, FIG.
As shown in FIG. 0 and FIG. 11, the arm 8 is rotatable with respect to the armor part 9, and the armor 7 is in contact with the central part 7 a pressed against one side of the prism 11 a of the armor part 9.
And the arm 8 whose end is fixed to the column 11b of the armor part 9.
And are connected.

When the arm 8 is rotated in the direction of arrow E in FIG. 10 to make it as shown in FIG. 11, the armor part 9 has one side of the prism 11a with respect to the center 7a of the armor 7. Deviates from line contact or surface contact. Then, a force (in the direction of arrow F) for returning to the original state is generated due to the disengagement, and this acts as a spring property other than the spring property of the arm 8 itself. In addition, this spring property can be adjusted by adjusting the pressing state at the time of contact between the central portion 7a of the armor 7 and one side of the prism 11a of the armor part 9, and the size of the contact portion.

The maximum rotation of the arm 8 is determined by contacting the folded portion 7b of the armor 7, and the arm 8 does not climb over the corner of the prism 11a at this contact. Thereby, when the arm 8 is released, the initial state,
That is, the central portion 7a of the armor 7 is
It returns to a state of line contact or surface contact with one side of “a”.

As described above, the hole provided at one end of the armor 7 connected to the arm 8 via the armor part 9 is aligned with the hole provided at the outer portion of the lens 2 and screwed. 2 can be fixed. Therefore, by fixing to the outer portions of the pair of lenses 2 and 2 whose inner portions are connected by the bridge 3, respectively, in addition to the resiliency of the arm 8, the armor 7, the armor parts 9 and the arm 8 The eyeglasses can be made to have a spring property even at the connecting portion of.

FIGS. 8 and 9 show another example of the armor part 9.
