The present invention relates to a rimless glasses to be worn as a visual correction and decorative equipment, in particular, when the lens fastening position of the rimless glasses is proposed by a fixed structure for easy correction of the process of processing fasteners usually made by manual work Easily corrected the error in Essence to reduce the unnecessary loss of the lens to take advantage of economic benefits.

Glasses are worn before the eyes to correct the eyesight or to protect the eyes, and are divided into two types of corrective glasses and protective glasses according to the purpose of use.

In other words, correcting eye vision is called corrective glasses, and the eye is prevented from wind, foreign objects, chemicals, etc. in addition to obstacles from outer space such as ultraviolet rays, infrared rays, strong visible rays and radiation. It is called protective goggles.

Orthodontic glasses include myopia, primitive, astigmatism, and presbyopia. Protective glasses are commonly used for sunglasses, and special ones are dust-proof, underwater, windproof, and snow-proof with a barrier around the lens.

Such glasses are manufactured by combining the lenses divided into two sides together by the frames, the glasses legs, the nose rings, and the like, and glasses of various sizes and shapes have been released and used.

In particular, as glasses have a unique design and shape are released in order to produce a distinctive production in recent years, it is possible to select and wear glasses suitable for individual tastes.

In addition, in recent years, rimless glasses with esthetic glasses and aesthetic elements added to meet the tastes of various consumers are widely used. Such rimless glasses have a pair of lenses having an appropriate curvature according to the degree of lens. The separate bridge is connected to each other, and the opposite ends of the bridge connecting portion of each lens is completed by folding the eyeglasses with a hook so as to be hooked to the user's ear.

That is, as shown in FIGS. 1 and 2, the lens 100 and the bridge 101, the lens 100 and the eyeglass leg 102 are coupled by separate fasteners, respectively, which fasteners A bolt 103 that penetrates one end or both ends of the bridge and the lens at the same time; A part of the lens 100 is inserted into the lens from the inner surface of the lens 100 and the soft plastic through which the bolt penetrates to close the gap between the lens and the bolt with a cushion to prevent the lens from moving and loosening the screw. Sleeve washer 104; The nut 105 is fastened to the bolt protruding through the sleeve washer and serves to squeeze the lens and the frame vertically.

Such rimless glasses typically have the bolt 103, the nut 105, and the sleeve washer in the state in which the fastening hole 106 is formed through the two sides of the lens 100 while the lens is processed. It is completed by firmly fastening the bridge 101 and the glasses leg 102 using the 104.

However, there is a problem that the lens for the frameless glasses as described above may not be fastened to a uniform and accurate position due to irrationality in the processing process of the fastening hole.

In this case, when the fastening hole is formed at the wrong position, the assembly of the lens is impossible, and even if the case is formed at the wrong position, the angle of the lens is severely distorted or tilted even by a very minute difference. This will happen.

Therefore, the rimless glasses assembled as a result of fastening holes in the wrong position are often classified as defective products during the manufacturing process, and the lens must be discarded. Since the customer claims are generated from the customer, the loss of reliability is caused, as well as the enormous loss of property in the process of exchanging or refunding defective items.

In particular, when a fastening hole is formed at a minutely wrong position as described above, the fastening hole cannot be reworked to another position, that is, an accurate position, and thus the lens must be discarded as it is. In case of economic loss is considerable.

The present invention is to solve the problems as described above, when the lens of the rimless glasses due to the incorrectly processed fastening hole is inclined or inclined by the eccentric side in the expanded process of the fastening hole in the eccentric direction A frameless lens for inserting a fixed bushing into the fastening hole to correct the center of the fastening hole and reusing the lens while forming the best wearing condition according to the shape or shape of the user's face. It is an object of the present invention to provide a position correction method and a fixture for position correction.

The present invention for achieving the above object, to form an upper flange, the lower side of the flange to form an insertion portion, the fixing bushing to form an eccentric side portion of the form extending to one side of the insertion portion, The assembly hole of the vertical through-hole formed in the fixed bushing is to be formed by moving the center according to the amount of protrusion of the eccentric side portion, the fixed bushing having the eccentric side portion is provided with at least two or more types of protrusions of the eccentric side portion different from each other The fixed bushing may be selectively used according to the amount of eccentric machining of the fastening hole of the lens, and when the eccentric molding is performed due to the incorrect processing of the fastening hole of the lens, the fastening hole of the lens may be moved in the eccentric direction. Forming an extension machining portion, and inserting the insertion portion of the fixing bushing in the eccentric direction into a fastening hole having the extension machining portion The lip, is formed by configuring the eccentricity of the lens to be corrected.

According to the present invention, if an incorrect assembly or inclination of a lens occurs due to an incorrectly processed fastening hole, the center of the lens fastening hole is correctly corrected by a fixed bushing, so that the correcting and fastening operation of the lens can be easily reused. It can be very economical, it is possible to finely adjust the assembly position of the lens to maintain the optimal wearing state according to the shape or shape of the user's face of the wearer can provide a more reasonable effective form of rimless glasses.
