Description

[Detailed description of the invention] A grooved lens is fitted into the upper frame of eyeglasses, and each end of a nylon thread or thin metal wire is inserted into two holes provided in the inner and outer side pieces of the upper frame. Eyeglasses are well known in the art, in which the lens is held by the upper frame and the nylon thread or thin metal wire.

Among these conventionally known eyeglasses, those using nylon threads are easy to fit into the frame because the nylon threads expand and contract to some extent, but when the temperature is high, the nylon threads stretch and the lenses tend to come off.

Also, if you use a metal wire, if the metal wire is slightly short, I think it will fit from this point, but if you try to force the lens to fit, the edge of the lens groove will chip, so insert the metal wire at the edge of the upper frame. The length must be adjusted at the insertion section, and when replacing the lens, the same adjustment must be done at the insertion section, which is inconvenient.

Furthermore, since the ends of both the nylon thread and the metal wire are simply passed through two holes, there is a possibility that the thread or metal wire may be pulled and loosened at the insertion portion, and the lens may come off.

The present invention aims to provide a type of eyeglasses in which the lenses are tightened with nylon threads, metal wires, etc., in which the lenses can be easily attached and the lenses can be held securely. .

The present invention will be described with reference to an illustrated embodiment.

In glasses in which a lens with grooves around the circumference is fitted to the upper frame of the glasses, and synthetic fiber threads or thin metal wires are fitted and tightened into the grooves on the side and lower surfaces to hold the lenses, synthetic fiber threads or thin metal wires are used. Insert one end of 1 into the short cylindrical body 2, crush this cylindrical body to fix it, or provide a bulge in the part that protrudes from the short cylindrical body 2 to prevent it from coming off. Fix the synthetic fiber thread or thin metal wire 1 so that it does not come off, and attach the upper frame 3.
A horizontal hole 4 with a convex cross section for fitting the short cylinder 2 is provided at the end of the inner side piece of the holder, and a mounting piece 5 for fixing the other end of the synthetic fiber thread or thin metal wire 1 has a synthetic fiber thread or Two holes 6 and 7 are provided for the insertion of thin metal wires, a screw insertion hole 8 is provided on the outside, and the mounting piece 5 for the thread, metal wire, etc. Recessed part 9 that seems to fit
A cylinder body 10 provided with a female thread is buried in this recess so as to communicate with the screw insertion hole 8 provided in the mounting piece 5, or a screw is provided on the outside of the cylinder body 10 and screwed into the cylinder body 10. The short cylindrical body 2 is fitted into the horizontal hole 4 of the inner side piece of the upper frame 3 by inserting a synthetic fiber thread or thin metal wire 1 from the outside, and the other end of this thread or metal wire is attached to the mounting piece 5. Insert it through the inner hole 6, then insert it into the adjacent hole 7 and take it out, adjust its length to an appropriate length to surround the lens, and fit this thread or thin metal wire into the groove of the lens to surround it. , the mounting piece 5 is fitted into the recess 9 at the lower end of the outer side piece of the upper frame 3, this is tightened with a screw 11, and the lens is fixed by tightening with this thread, wire, etc. be.

According to the present invention, one end of the synthetic fiber thread or thin metal wire that is fitted into the groove of the lens and tightens and fixes the lens is fixed to the short cylinder 2 so as not to come off. Attach it by fitting it into the horizontal hole 4 of the side piece, insert the other end into the two holes 6 and 7 of the mounting piece 5 in sequence, fit the lens into the groove of the upper frame 3, and insert the synthetic fiber thread or thin metal wire into the groove of the lens. , fit the mounting piece 5 into the recess 9 provided on the lower end surface of the outer side piece of the upper frame, screw the screw 11 into the screw hole of the cylinder 10 embedded in the recess, and then insert the mounting piece 5 into the recess of the upper frame. 9, and the lens is tightened and fixed using a synthetic fiber thread or thin metal wire 1 whose end is inserted through the hole in the mounting piece 5, so the two holes 6,
The synthetic fiber thread or metal wire exposed over 7 is pressed against the bottom surface of the recess 9 and the mounting piece 5 and does not come out of the hole, and as described above, one end of the synthetic fiber thread or metal wire is fixed to the short cylinder 2, and this Since the short cylindrical body is fitted into the horizontal hole in the inner side piece of the upper frame, the lens is always held securely without loosening of either the synthetic fiber thread or the metal wire. Further, even if the synthetic fiber thread or metal wire has a length slightly longer than a predetermined length, the lens can be properly tightened and fixed by adjusting the screwing amount of the screw 11 of the mounting piece.
