Description

[Detailed Description of the Invention] The present invention relates to a temple inclination angle measuring device for eyeglasses.

Since the glasses are arranged so that the lenses are almost perpendicular to the line of sight, the angle (shown as α in FIG. 1) between the center line of the temple and the perpendicular to the front surface.
This angle (hereinafter referred to as the temple inclination angle) is normally set at several to ten-odd degrees, but if the brazing position of each part is shifted, the desired temple inclination angle cannot be obtained, and in this case, it may be inappropriate for the eyes. glasses.
Conventionally, the temple inclination angle was measured visually to select good or defective products, but the front rim itself is curved along the lens curve, and both rims are connected at an angle. The temple has a complex curved surface that is curved, so visual measurement of the temple inclination angle lacks accuracy.

In view of the above points, the present invention provides an apparatus that can easily and accurately measure the temple inclination angle by simply setting both limbs on a holding stand and aligning the axis of the temple with the reference part.

Embodiments of the present invention will be described below based on the drawings.

A first rotating rod 2, which is T-shaped in side view, and a second rotating rod 3, which is arrow-shaped in side view, are each rotatably supported on a base 1 having a horizontal surface. They are rotatably connected by a link 4. A pair of holding rods 5a and 5b serving as a glasses holding stand 5 are provided on the upper part of the first rotary rod 2,
One holding rod 5a is fixed, the other holding rod 5b
is attached with a screw 6 so that it can move along the hole 2a in the upper part of the rotating rod 2, as shown in FIG.
The plane formed by the rotating rods 2 and 3 is substantially orthogonal to the rotating plane of the rotating rods 2 and 3. Further, fixed to the pivot portions of the base 1 and the second rotary rod 3 is a display portion 7 carved with an angle.

Next, to explain the method of measuring the temple inclination angle, first, both the left and right rims 8a, 8b of the glasses are placed on the above-mentioned both holding rods 5a, 5b, and the center part of both rims 8a, 8b is Hold the rod 5
Fix it to a, 5b. At this time, it is necessary to fix both rims perpendicularly to the rotating surfaces of the rotating rods 2 and 3, but each rim 8a and
If the central portion of the rim 8b is supported, the rim and the holding rod come into point or line contact, so even if the rim is curved, the rim can be easily set. Next, the rotating rods 2 and 3 and the link 4 are rotated to align the axis of the temple 8c with the reference portion 11. This reference part 11 serves as a reference for angle measurement, and in order to make it easier to align the axis of the temple 8c, it is optimal to have an inverted T-shaped reference member 12 marked with the perpendicular line 11 of the base 1. You may use a ruler or use an angle other than a perpendicular line.
When both the rims 8a and 8b of the glasses are fixed to the glasses holder 5 in this way and the temples 8c are aligned with the reference part 11, the temple inclination angle α is adjusted based on the second rotating rod 3 as shown in FIG. It can be expressed by the angle formed with the perpendicular line of the table 1, and this angle is read from the lower end of the rotary rod 3 and the display section 7 to select good and defective products.

In the above embodiment, the display unit 7 is provided on the second rotating rod 3 and the pivot portion of the base 1, but the display is displayed using the first rotating rod 2 that moves parallel to the second rotating rod 3. It is also possible to read the display section 7, and as shown in FIG.
may be fixed, and the rotating rod 2 may be pivotally supported on this display section 7.

As described above, the temple inclination angle measuring device for glasses according to the present invention includes at least one rotary rod that is rotatably supported with respect to the base, and that is provided on the rotary rod and that connects both the left and right rims of the glasses to the rotary rod. The glasses holder is equipped with a glasses holder that is held approximately perpendicular to the rotating surface, a reference part that aligns the axis of the temples of the glasses, and a display part that displays the rotation angle of the rotating rod. The temple inclination angle can be accurately measured by an extremely simple operation of holding both limbs in place and aligning the temple with the reference part in this state.
