Description

[Detailed description of the invention] There are two types of rimless glasses: those whose lenses are held using nylon, and those whose lenses are held using a thin metal wire. In the former type of glasses, the nylon thread has elasticity, so the lenses can be easily fitted and removed from the ring-shaped nylon thread frame. Since the thin metal wire of the latter type of glasses does not have elasticity, some methods have been devised to hold the lenses, but none of them have a simple structure and are easy to tighten.

The present invention was devised in order to eliminate the above-mentioned drawbacks of the conventional eyeglasses.

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

In the case shown in Figures 1, 2, 3, 4, and 5, a lens holding upper frame 3 having a protrusion 2 on the lower surface is fixed to the inner surface of the bridge 1 so that the upper edge of the grooved lens fits into it.
A plurality of holes 5 for inserting a thin wire 4 for tightening the lens are provided at the inner end of the frame, and a recess 6 with a triangular cross section is provided at the end surface of the outer end. A tightening body 8 has a screw hole 9 in its center and a protrusion 7 having a triangular cross section on its end face so as to fit into the recess 6. A hole 12 for screw insertion is provided in the center of the tightening body 8, and a hole 12 for screw insertion is provided in the lower part of the tightening body 8, which protrudes in the extension direction. A piece 10 is provided, a plurality of holes 11 for inserting the wire 4 are provided in the projecting piece 10 close to each other, a screw 13 is inserted into the hole 12 of the clamping body 8, and a screw hole 9 of the upper frame 3 for holding the lens is inserted. This is characterized in that the upper frame body and the clamping body are connected by screwing into the body.

Also, what is shown in Fig. 6 is the upper frame 3 for holding the lens.
A cylindrical body 14 is provided at the outer end of the cylindrical body 14, a screw hole 9' is provided in the center of the end, and the tightening body 8' is attached to the cylindrical body 14.
A hole 12' for screw insertion is provided in the center of this fastening body 8', and a protruding piece 10' is provided in the lower part in the extending direction, and a wire 4 can be inserted into this protruding piece. A plurality of common holes 11' are provided close to each other, a tightening body 8' is inserted into the cylindrical body 14, a screw 13' is inserted into the hole 12' formed in the center, and the screw of the upper frame 3 is tightened. This is characterized in that the upper frame for holding the lens and the clamping body are connected by screwing into the hole 9'.

In any embodiment of the present invention, the wire 4
The ends of the wire are inserted into the holes 5 at the inner end of the upper lens holding frame 4 in order and fixed, the wire is cut to a length suitable for tightening the lens, and the end is inserted into the tightening body. Insert the protruding pieces 10, 10' of the parts 8, 8' into the holes of the protruding pieces 10, 10' in order and fix them, and then insert the screws 1 into the holes of the clamping bodies 8, 8'.
3 and 13' are inserted into the screw holes 9 and 9' of the upper holding frame 3, and the wire 4 and the lens held by the upper frame 3 are tightened and fixed.

According to the present invention, when there is a large difference between the space surrounded by the upper lens holding frame 3 and the wire 4 and the size of the lens, fine adjustment is made by adjusting the threading depth of the holes 11 and 11' through which the wire is passed. This can be adjusted by tightening the screws, which has the excellent effect of allowing the lens to be reliably attached to the eyeglass frame. Further, since this fine adjustment can be done simply by turning the screw with a screwdriver, there is an advantage that it can be easily done not only by retailers but also by users.
