[0096] A preferred first embodiment of the optometry frame of the present invention will be described in detail with reference to the drawings.
[0097] [Front frame]
[0098] figure 1 It is a figure explaining the structure of the front frame concerning the 1st Embodiment of the optometry frame of this invention, wherein (a) is its front view, (b) is (a) X-X direction cross-sectional view, (c) is its top view, (d) is its bottom view, (e) is its right side view. In addition, since the left view and the right view are symmetrical, illustration is omitted.
[0099] The front frame 1 of the optometry frame of the present invention is formed of resin or metal, and has left and right ring-shaped holding frames 11 holding unshown test lenses, nose bridges 101 connecting the left and right holding frames 11, and formed on the left and right sides. The stake head 102 at the end of the holding frame 11. In addition, temples (not shown) are foldably connected to the left and right ...

[0122] In the first embodiment described above, the rotating ring 31 is attached to the holding frame 11 through the fixing ring 21 so that the rotation angle position can be adjusted freely.
[0123] Figure 6 (a) and (b) are diagrams showing a second embodiment in which one rotating ring 32, 32' is mounted to the holding frames 12, 12' without the fixing ring 21, and are equivalent to ( c) A partial view of a partially enlarged cross-sectional view of part III.
[0124] Figure 6 The rotating ring 32 in the example of (a) has a ring-shaped main body 32b and a fitting part 321, wherein the ring-shaped main body 32b has a lens holding part 322 formed with a lens holding groove 322a for holding a test lens T, The fitting portion 321 is formed on the main body 32 b and is inserted into the through hole 12 a of the holding frame 12 . A concave portion 321 a having the same groove width as the thickness s of the holding frame 12 is formed on the fitting portion 321 . Moreover,...

[0128] Figure 7 It is a diagram showing a third embodiment in which another rotating ring 33 is attached to the holding frame 13 instead of the fixed ring 21 of the first embodiment, and is a part corresponding to a partially enlarged cross-sectional view of part III in FIG. 4( c ) diagram.
[0129] exist Figure 7 In the example, one rotating ring 31 uses the same rotating ring as the rotating ring 31 of the first embodiment, therefore, in Figure 7 The same reference numerals as those of the rotary ring 31 of the first embodiment are assigned to the same reference numerals, and detailed descriptions will be omitted in the following description. In addition, the basic configuration of the other rotating ring 33 is the same as that of the fixed ring 21 of the first embodiment, but differs in that it is not fixed to the holding frame 13 and can rotate freely.
[0130] On the ring-shaped main body 33b of the other rotating ring 33, the same as the fixed ring 21 of the first ...
