Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eyeglass frame having a structure in which approximately the upper half of an eyeglass lens is supported by an upper rim and approximately the lower half of an eyeglass lens is supported by a nylon thread.

[0002]

[Prior art]

 Conventionally, in this type of spectacle frame, a nylon thread is engaged with a groove formed on the outer peripheral surface of the spectacle lens, and both ends thereof are respectively connected to the ends of the upper rim. Further, the upper rim is slightly wider than the outer shape of the spectacle lens before the spectacle lens is attached, and is biased inward by attaching both ends of the nylon thread to engage with the outer peripheral surface of the spectacle lens.

[0003]

[Problems to be solved by the device]

 Since the conventional spectacle frame has such a structure, if the nylon thread is broken, the upper rim is opened to its original state, which causes a problem that the spectacle lens falls.

In view of the above problems, it is an object of the present invention to provide an eyeglass frame in which the eyeglass lens does not drop even if the nylon thread that holds the lower side of the eyeglass lens is cut.

[0005]

[Means for Solving the Problems]

 The spectacle frame according to the present invention is characterized by having an upper rim that engages with the outer peripheral surface of the approximately upper half of the spectacle lens, and a pin that is attached to this upper rim and whose tip is embedded in the spectacle lens.

[0006]

【Example】

 The present invention will be described below with reference to illustrated embodiments. 1 to 5 show a first embodiment of the present invention.

The spectacle frame has upper rims 13 and 14 that engage with outer peripheral surfaces of substantially upper halves of the pair of spectacle lenses 11 and 12, respectively. The upper rims 13 and 14 are connected by a bridge 15 and a wading 16 located above the bridge 15. Pads 18 are attached to the inner lower ends of the upper rims 13 and 14 by pad feet 17. A temple (not shown) is connected to the outside of the upper rims 13 and 14 via the end piece 21.

As shown by the solid line in FIG. 2, in the manufacturing process, both end portions 13a and 13b of the upper rim 13 are bent inward as compared with the shape when the spectacle lens 11 is attached. That is, the distance between both ends 13a and 13b of the upper rim 13 is shorter than the distance between the corresponding portions of the spectacle lens 11 before the spectacle lens 11 is attached. Therefore, in the state where the spectacle lens 11 is attached, the upper rim 13 spreads outward as shown by the broken line and has a spring force for sandwiching the spectacle lens 11. Similarly, the other upper rim 14 also has a spring force for sandwiching the spectacle lens 12.

Pins 22 made of synthetic resin or metal are attached near both ends of the upper rims 13, 14. These pins 22 are screws, the tips of which are screwed into the spectacle lenses 11 and 12 from the outer peripheral surface and extend substantially parallel to the surfaces of the spectacle lenses 11 and 12. The pins 22 do not necessarily have to be screws, and may be columnar members that are simply embedded in the spectacle lenses 11 and 12. Further, only one pin 22 may be provided for one eyeglass lens.

As shown in FIGS. 3 and 4, the substantially lower half of the spectacle lens 11 is held by a first holding thread, that is, a nylon thread 23. A groove 24 is formed on the outer peripheral surface of the spectacle lens 11 over the entire circumference thereof, and the nylon thread 23 is engaged with the groove 24. The ends of the nylon thread 23 are fixed to both ends of the upper rim 13. That is, holes 25 and 26 are formed at both ends of the upper rim 13, and the nylon thread 24 extends from the groove 24 side through the hole 25 to the surface side of the upper rim 13 and further through the hole 26. It extends to the back surface of the upper rim 13 and engages with the groove 24. Similarly, a nylon thread that holds substantially the lower half of the spectacle lens 12 is also fixed to the other upper rim 14.

As shown in FIG. 5, a groove 27 is formed on the inner peripheral surface of the upper rim 13, and a second holding member is provided in a space formed by the groove 24 of the spectacle lens 11 and the groove 27 of the upper rim 13. A thread, that is, a nylon thread 28 is provided. The nylon thread 28 engages with the grooves 24 and 27, and thereby the spectacle lens 11 is fixed to the upper rim 13.

Since the present embodiment has the above-mentioned configuration, even if the nylon thread 23 is broken, the spectacle lenses 11 and 12 are connected to the upper rims 13 and 14 by the pins 22. Never fall out of. Further, since the upper rims 13 and 14 sandwich the spectacle lenses 11 and 12 by the spring back, the rims of the spectacle lenses 11 and 12 from the upper rims 13 and 14 are prevented from falling off double.

FIG. 6 shows another embodiment of the present invention. In this embodiment, a ridge 29 that engages with the groove 24 of the spectacle lens 11 is formed on the inner peripheral surface of the upper rim 13, and the spectacle lens 11 is separated from the upper rim 13 by the action of the ridge 13 b and the groove 24. Is prevented.

[0014]

[Effect of device]

 As described above, according to the present invention, even if the nylon thread that holds the lower side of the spectacle lens is broken, the spectacle lens does not come off from the upper rim, and the drop of the spectacle lens can be prevented.
