Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to frameless glasses that hold a lens without a rim.

[0002]

[Prior art]

 FIG. 5 is a specific example showing conventional general borderless glasses. Both lenses (a) and (b) are screwed together by the connecting member (b), and the outsides of the lenses (a) and (b) are attached with screws (c) and (c). I have. A crane (d) is attached to this yoke (c) via a joint so that it can be folded, and a nose pad (not shown) is attached to the inside of the lens (a) at the tip of a leg extending from the connecting member (b). E) is provided.

By the way, the two lenses (a) and (a) are screwed by a connecting member (b), and the lens (c) is screwed to the outside of the lens. When connecting and fixing to b), the structure must not rotate around the screw. The frameless frame adopts a structure in which the rotation of the lens is prevented by providing a contact piece (f) for contacting the outer periphery of the lens on the connecting member and the yoke (c). FIG. 5 (b) is an enlarged view in which the screw (g) is screwed to the lens. If the hole position of the lens (b) into which the screw (g) is inserted is not accurate, the contact piece (f) is It cannot be positioned against the outside.

[0004] That is, if the position of the screw hole is closer to the outside of the lens, a gap is formed in the hitting piece (f), and the yoke (c) is backlashed. C) cannot be installed. When a customer purchases eyeglasses, it is a retail store that decides which lens (a) suits their eyesight and processes the screw holes, but it is not easy to correctly process the screw holes.

By the way, the connecting member (b) and the yoke (c) are manufactured by forging a metal material and brazing it to another piece, so that it is a part exclusively for frameless glasses. In other words, there is no versatility, and by changing the form of the glasses, the connecting member and the lip can be changed. Each time a forging die must be manufactured, the cost is very high for small lots.

[0006]

[Problems to be solved by the invention]

 As described above, the conventional frameless glasses have the above-described problem. The problem to be solved by the present invention is this problem, and there is a connecting member that can be used even when the lens shape changes, and a frameless eyeglass having a royal part integrally formed with a crane on the outside of the lens. provide.

[0007]

[Means for solving the problem]

 In the frameless glasses according to the present invention, the two lenses are connected by a connecting member, and a royal part is attached to the outside of the lens. A crane extends from the royal part. In other words, the vine is integrated with the yoro, and there are no hinges or other joints between them. The vine is made of a material with excellent spring properties, and when the glasses are removed, the vine is greatly curved inward. When wearing glasses, the crane extends and a predetermined pressing force acts on the side of the face.

[0008] The above-mentioned yoroi part is screwed to the lens, and for that purpose, it has a hole through which a screw is inserted, and also forms a claw that comes into contact with the outer periphery of the lens. Then, the royal part and the vine are cut from a plate material having excellent spring properties, and the claws are formed by bending. Similarly, the connecting member is manufactured by cutting a plate material, and the claws are formed by bending. At the same time, the leg to which the nose pad is attached may be integrally formed. Here, since the claws can be bent according to the lens outer peripheral shape, there is versatility that can be used even if the lens changes. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

【Example】

 FIG. 1 is an embodiment showing the frameless glasses according to the present invention. 1 denotes a lens, 2 denotes a connecting member, and 3 denotes a crane. Both lenses 1 and 1 are connected by a connecting member 2. Mounted via. As is clear from the figure, the crane 3 is continuously integrated with the flap portion 4 and does not have a hinge as in the related art.

[0010] Therefore, the crane 3 is made of a material having excellent spring properties, for example, beta-titanium or the like. When wearing glasses, the vines 3, 3 are pushed outward and opened straight and extend straight, and the prescribed pressing force accompanying the spring force (elastic force) acts on the side of the face, causing the glasses to be displaced. No stability. At the same time as the glasses are removed, the vines 3 and 3 behave as if they were folded, and curve further inward when housed in the case.

FIG. 2 shows the crane 3, which is manufactured by cutting a plate material, and a modern 5 is inserted at the tip. Although the specific method of cutting is not limited, a plurality of sheets can be overlapped and wire cut. Also, it can be manufactured easily and efficiently by laser processing. At the end of the crane 3, a flap part 4 is formed, and the crane 3 and the flap part 4 are continuously integrated. A hole through which a screw is inserted is provided in the cover portion 4 and has two small claws 6 and 6. By laser processing, fine processing such as the above-mentioned nails becomes possible.

FIG. 3 shows a case in which the crooked portion 4 of the crane 3 is attached to the outside of the lens. The lip portion 4 is attached to the lens 1 by screwing. For this purpose, a through hole is provided in the lens 1 and a screw 6 is inserted. A nut is screwed into the screw portion on the back side of the lens and tightened. ing. Further, leaves 7, 7 are integrally formed as a kind of accessory pattern on the yoke portion 4 shown in the figure, and the leaves 7, 7 are in contact with the lens surface. Such an accessory pattern integrated with the yoke part 4 can also be easily formed by laser processing.

The claws 8 provided on the yoro part 4 are bent vertically and are in contact with the lens outer periphery 9. The claws 8, 8 are located at substantially equal distances around the screw 6, and are fixed to the lens 1 at three points so that the yoro part 4 is fixed to the lens 1 without rattling. The claws 8, 8 are bent after cutting the plate material in the state of FIG. 2, and the size of the claws 8, 8 is determined by the outer peripheral shape of the lens 1 and the position of the hole through which the screw 6 is inserted.

FIG. 4 shows a connecting member 2 for connecting the two lenses 1 and 1. The connecting member 2 shown in the figure is a cut-out state of the plate material, and holes 10 are provided on both sides for inserting screws 6, 6, and two claws 11, 11 are formed on both sides. Have been. The claws 11, 11... Are cut by laser processing and bent vertically to come into contact with the outer periphery 9 of the lens. Molded.

The cut connecting member 2 is formed with legs 12, 12, and has a substantially U-shaped clamping portion 13, 13 at the tip of the legs 12, 12. The nose pad is attached. Of course, the legs 12, 12 are appropriately bent so that the nose pad can hit the nose to support the front of the glasses.

As described above, in the frameless eyeglasses of the present invention, the connecting member for connecting the two lenses and the yoke portion attached to the outside of the lens are manufactured by cutting the plate material, and the claw hitting the outer periphery of the lens. Since it is bent, the following effects can be obtained.

[0017]

【The invention's effect】

 In the frameless glasses according to the present invention, the connecting member for connecting the two lenses is manufactured by cutting a plate material, and the claw corresponding to the outer periphery of the lens is formed by bending. In other words, there is no brazing point, and the cost is greatly reduced by manufacturing by cutting and bending. In addition, since the claws are bent according to the shape of the lens outer periphery, they can be brought into contact with the outer periphery of the lens without any gap. That is, unlike a lens forged by a metal mold, the present invention can be applied to lenses of all shapes.

[0018] On the other hand, the yoke portion is continuously integrated with the vine and cut, and there is no brazing portion. The production is simplified because there is no joint for folding the vine. Further, a claw corresponding to the outer periphery of the lens is formed in the yoke portion, and the claw can be formed by bending in accordance with the outer shape of the lens, so that it can be applied to any lens.
