Abstract

PROBLEM TO BE SOLVED: To provide a spectacle that supports a lens with spectacle parts other than a rim, that has no detent parts, and that does not require advanced technology in drilling a lens using a simple machine. Offer. SOLUTION: An uneven bush is provided on one side of a lens of a lens support component, the uneven portion being provided for preventing rotation of a lens fitted to the unevenness and preventing a lens crack due to direct contact between the lens support component and the lens. Is provided between the lens supporting part and the lens, a concave part for fitting the bush and a through hole for passing the lens set screw are provided in the lens, and the two parts and the lens are threaded or integrated with the lens supporting part. And fix it using a bar screw and a nut, washer or the like that fits it.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lens mounting structure for frameless glasses.

[0002]

[Problems to be solved by the invention]

 In conventional frameless spectacles, the parts for supporting the lens are brazed to the side of the lens along the outer shape of the lens to prevent the lens from rotating, or the parts for supporting the lens Parts that are integrated with parts are made using a press or a cast. However, brazing is difficult with final separation for integrated parts.

[0003] Also, in the processing of a lens hole at a general retail store, the tolerance of the distance from the lens edge to the hole is small, and a technique is required. A slight displacement of the hole may cause a lens crack or the lens may be broken. Since it becomes unusable and a new lens must be reworked, specialized high technology is required.

In addition, since the lens rotation stopping part requires a certain length, there is a restriction in design. In particular, when the same lens support component is used and a lens having a different shape is employed, design restrictions on the lens shape are large. An object of the present invention is to provide a method for fixing a lens in frameless eyeglasses that can solve the above problem.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention employs the following solutions. In spectacles in which the lens is supported by metal parts other than the rim, one of the irregularities is provided on the lens side of the lens supporting part (1), and the lens is prevented from rotating to fit into the irregularity and the lens is broken by the direct contact between the lens supporting part and the lens. A bush (3) having projections and depressions is provided between the lens support part (1) and the lens (4) to prevent the recess, and the lens (4) is used to pass the recess fitting the bush and the lens set screw. The through-hole is provided, and the two parts of the lens support part (1) and the bush (3) and the lens are passed through the screw (2) or the rod screw (7) integrated with the lens support part and the nut that fits it (6) Fix using a washer (5) or the like.

[0006]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. In FIGS. 1 to 6, the lens support component (1) is provided with either a concave or a convex on the lens side like AA in FIG. 5 and BB in FIG. 6.

[0007] The bush (3) is made of an elastic plastic material and has unevenness to be fitted into the unevenness of the lens support part on one side as shown in Figs. A through hole is provided for the set screw.

As shown in FIG. 9, the lens (4) is provided with a concave portion to be fitted to the bush and a through hole for passing the lens set screw.

As shown in FIGS. 5 and 6, the lens support component, the bush, and the lens are fixed using screws (2) and (7) and washers (5) and nuts (6) that match the screws.

[0010]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

Since the bush (3) also functions as a lens rotation preventing part, the lens rotation preventing part is not required, and the design restriction is reduced.

The same lens supporting part (1) can cope with any lens shape.

[0013] Since the bush (3) serves as a buffer between the lens and the lens support component, lens breakage is reduced.

At the time of processing a lens at a retail store, there is no lens rotation preventing part, so there is no need to finely adjust the distance from the lens end to the lens screw hole, and it is easy to use a simple machine without the need for advanced technology. Grooves and through holes can be machined.
