Description

[Detailed Description of the Invention] The present invention relates to an improvement of an eyeglass lens support device in which a metal frame and a lens are provided with grooves, respectively, and a string-like connecting material is disposed between both grooves.

As the above-mentioned connecting materials, various string-like materials made of polymer compounds with consideration given to the cross-sectional shape have been proposed.
Among these, many were weak and prone to detachment at the supporting portion.

The present invention was devised for the purpose of eliminating the above-mentioned drawbacks, and its configuration is explained with reference to the drawings. Figure 1 is a back view of glasses equipped with the lens support device of the present invention, and Figure 2 is an enlarged view of the main part of Figure 1. 3 and 4 are a front view and an end view of the connecting material, and FIG. 5 is a diagram showing an aspect of the present invention before the connecting material, metal frame, and lens are engaged with each other.

In the drawings, 1 is an eyeglass fitting lens, 2 is a concave groove provided on the outside of the lens, 3 is a concave groove provided on the outside of the lens, 4 is a concave groove provided inside the upper frame, and 5 is a stainless steel wire rope or the like inside the main body. A string-like tie material made of a polymer compound is shown in which a metal wire 6 is enclosed and a longitudinal protrusion 7 is attached to the outside.

Reference numeral 8 denotes a thin wire that supports the lower half of the lens, and both ends of the wire are inserted and locked into mounting holes 9 drilled near both ends of the upper frame 3.

The string-like connecting material 5 constituting the main part of the spectacle lens support device of the present invention is constructed by engaging the main body portion with the groove 1 of the upper frame 3 and the protrusion 7 portion with the groove 2 of the lens 1. This is to ensure the contact between the frame 3 and the lens 1, and since a metal wire 6 is enclosed in the main body, there is no risk of melting and collapsing when fitting, and the operation can be performed easily and accurately. After fitting, the metal wire serves as the core, so even if it is exposed to heat, it will not deform and escape from the groove 4, and the main body has a strong structure as described above. As a result, the protrusion 7 portion is also reinforced, and the locking with the concave groove 2 of the lens is strong.

There are no limitations on the material, specifications, etc. of the metal wire 6, but especially the third
When using stainless steel wire rope as shown in the figure,
It is most suitable as a core wire because it has a strong structure, has no risk of deterioration, and has good adhesion to the polymer compound that envelops it.
