Abstract

PROBLEM TO BE SOLVED: To enable la measuring frame to accurately and rapidly measure the arm length of spectacles with various sizes of frame width by an arm length measuring frame for frames of various sizes with a feeding wheel and to utilize measured results for adjusting a drawing of spectacles. SOLUTION: The feed screw 3 of the measuring frame 1 with graduation for frames of various sizes is provided with a moving part 4 for various kinds of frame width. An arm sending device part 12 attached to a hinge 7 of the moving part 4 is provided with the feeding wheel having a lacking part and the feeding part 14. A measuring arm 8 with an irregular surface 10 and the measuring graduation 11 is attached thereto to surely measure arm length. Further the measuring frame 1 with graduation is made to be linear and a fixed nose pad 6 and the hinge base 7 are set at zero positions and accurate measurement from a nose 21 till an ear 20 is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the measurement of arm lengths of various large and small frames.

[0002]

2. Description of the Related Art Conventionally, since eyeglasses are adjusted by face matching and technology, there is no arm length measuring device for various frame widths of eyeglasses, and it is inaccurate to adjust eyeglass drawing.

[0003]

Since the conventional eyeglass adjustment has been performed using a long-standing technique, there are many technical differences between individuals, and there has been a problem that it is difficult to adjust the arm length with a different eyeglass frame width.

In the present invention, the width of the measurement frame can be freely changed, the measurement can be easily performed by a feeder, and when the angle of the measurement arm hits the ear, the movement stops and the measured value can be understood. The purpose is to provide accurate arm length measurement with a graduated measurement arm and a straight graduation measurement frame with a fixed nose pad and hinge at zero position from the nose to the ear. And

[0005]

In order to achieve the above object, various frame widths can be set for the scaled measuring frame width of the present invention via a feed screw and a moving portion. The arm length can be measured.

The moving arm hinge provided on the frame scale plate is attached to the hinge of the measuring arm feeder, and the feeder is provided with a feed wheel having a defective portion and a feeder, so that the movement and stopping of the measuring arm is effective. Can be done.

[0007] An uneven surface is provided on the measuring arm,
It is preferable to attach a measuring arm scale so that the measuring arm can move smoothly and the measuring arm length can be immediately known.

Further, it is preferable that the measurement value of the arm length from the nose to the ear be obtained by setting the fixed nose pad and the hinge base to the 0 position by using a linear scaled measurement frame.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, bearings 3 'are provided at the center and both ends of the measuring frame 1 with the scale for large and small frames, and feed screws 3 are separately provided. A moving portion 4 with a mark 5 is attached to the feed screw 3, and a measuring frame 2 for large and small frames is provided at both ends of the measuring screw 1 with a scale for large and small frames at both ends of the back feed screw 3 for moving the moving portion 4.

In the embodiment shown in FIG. 2 and FIG. 3, an arm feeder unit 12 is provided on both hinges 7 of the moving unit 4. The measuring arm 8 feeder is a feeder with a V-shaped feed unit 14 and a defective portion 15. 13
The two wheels 18 on the upper side of the arm feeder unit 12 are attached to move the measuring arm 8 smoothly, and when the measuring arm ear angle 9 hits the ear 20, the defect 15
, The movement is stopped, and at the same time, the fixed arm length measurement is completed with the fixing screw 17.

In the embodiment shown in FIGS. 2 and 3, the uneven surface 10 is provided on a part of the measuring arm 8 so that the feed wheel 13 can move smoothly. Also, a measurement arm scale 11 is provided on the measurement arm 8 to quickly measure the arm length.

The fixed nose pad 6 and the hinge base 7 of the measuring frame 1 with the scale are set to the 0 position, the arm length from the nose 21 to the ear 20 of the wearer is measured, and the time can be shortened because the arm scale 11 can be immediately recognized. Can be helpful.

[0013]

Since the present invention is configured as described above, the following effects can be obtained.

The width of the arm can be changed with one arm length measuring frame for the large and small frames with a feeder, and the arm length measurement of various measuring frame widths can be performed accurately and in a short time.

Then, when the movement of the measuring arm and the angle of the ear of the measuring arm hit the ear with the feed knob of the feeder wheel provided with the feeding portion and the defective portion, the arm stops at the defective portion, so that the accurate arm length can be measured. .

In addition, since the measurement arm is provided with an uneven surface to facilitate movement, and the accurate arm length can be immediately known from the measurement arm scale, the eyeglass frame arm length drawing in millimeter units can be adjusted.

The arm length from the nose to the ear can be easily measured with the measuring arm scale by setting the fixed nose pad and the hinge base of the measuring frame with the scale at the 0 position.
