Things have happened. The present invention aims to solve the above problems. [Structure] A spectacle frame 1 is divided into a left frame 2 and a right frame 3 at a central portion thereof.
1. The upper-side bridging part 5 and the middle-side bridging part 12 are formed to extend in the right frame 3. Further, the connecting member 8 is fitted to the upper side connecting portions 4 and 5, the adjusting screw tube 15 is screwed into the intermediate side connecting portions 11 and 12, and the adjusting screw tube 15 is turned to rotate the intermediate side connecting portions 11 and 12.
And adjust the interval between the upper side crossovers 4 and 5 to adjust
0 and 10 are screwed from the long hole 9 of the connecting member 8 into the screw holes 6 and 7 of the upper side crossing portions 4 and 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spectacle frame capable of adjusting a pupil distance, in which a distance between crossovers of spectacles can be adjusted to match a pupil distance of a spectacle user.

[0002]

[Prior art]

 At present, there is no spectacle frame capable of adjusting the distance between the crossing portions of the spectacles so as to match the pupillary distance of the spectacle user.

[0003]

[Problems to be solved by the device]

 As the number of elderly people increases, the number of people who use reading glasses has increased. Recently, reading glasses with bifocal functions have been widely used, but cumulative multifocal lenses and bifocal lenses are used for this type of reading glasses, which is different from the conventional single focus lens. If you do not adjust it correctly, it will be difficult to correct your eyesight. The present invention aims to solve the above problems.

[0004]

[Means for solving the problem]

 In order to solve the above-mentioned problems, in this invention, the spectacle frame is divided into left and right parts at the central part, the crossover parts are formed to extend on the upper sides of both frames, and a pipe-shaped connecting material is provided at both crossover parts. Fit. In addition, the crossovers are formed to extend in the middle sides of both frames, and opposite crosswise male screws are provided on both crossovers. Further, the male screw is fitted with an adjusting screw cylinder in which female screws suitable for the male screw are formed on the left and right. After turning the adjusting screw tube to adjust the interval of the transition part on the middle side of the frame, fix the adjustment state by screwing the connection part of the upper side of the frame and the connecting material to optimize the interval of the transition part of the eyeglass frame. Adjust to a proper state.

[0005]

[Operation] Since the connecting material was fitted in the transition part on the upper side of the frame, and the adjustment screw tube was screwed into the transition part on the middle side of the frame, if the adjustment screw tube is turned, the transition part of the middle side of the frame will move in the width direction. It expands and contracts, and the crossover of the upper side of the frame also expands and contracts in the width direction. Therefore, by screwing both ends of the connecting part on the upper edge of the frame, the adjustment state of the connecting part is fixed, the distance between the centers (focal points) of the left and right lenses fitted in the eyeglass frame is adjusted, and the pupil The distance can be adjusted.

【Example】

 Next, an embodiment of the present invention will be described. The spectacle frame 1 is made of a metal such as titanium, and cut from the center of the frame to be divided into a left frame 2 and a right frame 3. An upper side crossover portion 4 is provided extending to the right side of the left side frame 2, and an upper side crossover portion 5 is provided to extend to the left side of the right side frame 3 (see FIGS. 1 and 1). (See Figure 2). As shown in the drawing, the upper side crossing portions 4 and 5 are rod-shaped with a pentagonal cross section or a quadrangular cross section, and screw holes 6 and 7 are provided in the central portions thereof. A connecting member 8 is fitted between both ends of the upper side connecting portions 4 and 5. The connecting material 8 is made by cutting a metal pipe having an inner diameter corresponding to the cross-sectional shape of the upper side crossing portions 4 and 5 into an appropriate width. As shown in FIG. 4 and FIG. Long holes 9, 9 are provided in the lateral direction. The long holes 9 and 9 of the connecting member 8 correspond to the screw holes 6 and 7 of the upper side connecting portions 4 and 5, and the machine screw 10 is provided from the long holes 9 and 9 of the connecting member 8 to the screw holes of the upper side connecting portions 4 and 5. If they are screwed into 6 and 7, they will be tightly screwed together. Further, a middle side crossing portion 11 as shown in FIG. 6 is provided extending to the right side of the left side frame 2, and a middle side crossing portion 12 is also extended to the left side of the right side frame 3. It is provided. Male screws 13 and 14 in opposite directions are formed on the middle-side connecting portions 11 and 12, respectively, and an adjusting screw cylinder 15 is screwed onto the male screws 13 and 14. The adjusting screw cylinder 15 has a cylindrical shape whose surface is knurled, a through hole 16 is provided inside, and the middle side connecting portions 11 and 12 are provided on the left and right sides of the through hole 16. The female screws 17 and 18 in the opposite directions are formed so as to match the male screws 13 and 14 of FIG. Reference numerals 19 and 19 in the drawing denote spectacle lenses fitted to the spectacle frame 1.

If the female screws 17 and 18 of the adjusting screw cylinder 15 are screwed into the male screws 13 and 14 of the intermediate connecting parts 11 and 12, respectively, and the adjusting screw cylinder 15 is turned, the intermediate connecting parts 11 and 12 are turned. The space between them expands and contracts in the width direction, and at the same time, the interval between the upper side crossing portions 4 and 5 also expands and contracts in the width direction. Next, the elongated holes 9 and 9 of the connecting member 8 are positioned in the screw holes 6 and 7 of the upper side crossing portions 4 and 5 so that the elongated holes 9 and 9 come to the back surface side of the eyeglass frame 1, and the elongated holes 9 and 9 are screwed to the screw holes 6 and 6. 7 is screwed into the machine screw 10 so that the adjustment state of the crossover portion is maintained. FIG. 8 shows a state in which the distance between the upper and middle sides is slightly narrowed.

[0008]

[Effect of device]

 In the spectacle frame 1 of the present invention, by rotating the adjusting screw cylinder 15, the interval between the upper and middle sides can be adjusted, so that there is an effect that it can be adjusted to match the pupillary distance of the spectacle user. Further, there is an effect that by simply turning the adjusting screw cylinder 15, the distance between both the upper and middle sides can be adjusted at the same time. Furthermore, if the upper side crossing portions 4 and 5 and the connecting material 8 are coupled with the machine screw 10, there is an effect that the adjusted state of the upper and middle side crossing portions of the spectacle frame 1 is maintained. Furthermore, since the transition portion is provided in two steps, the upper side and the middle side, the adjustment state is accurately fixed and can be maintained for a long period of time. Since the machine screw 10 comes to the back surface (inner side) of the spectacle frame 1, it also has an inconspicuous effect.
