In general, rimless glasses are worn without a frame surrounding the lens with a pair of lenses fixedly arranged between the legs and the bridge. Such rimless glasses are lighter in weight than ute glasses and have a refined design. Recently, rimless glasses are more preferred than ute glasses.

Such a conventional rimless eyeglass has a fastening bolt perpendicular to the fastening hole and the transverse direction of the lens so that one side is pivotally coupled to the hinge portion of the glasses leg and the rear side of the lens side is press-contacted in front of the fixing frame having the fastening hole on the other side. Screwed in the direction and the side portion of the lens is in contact with the inside of the engaging portion protruding forward of the fixed frame.

In a similar manner, the other side of the lens is press-coupled by a fastening bolt to one front surface of the bridge.

However, in the conventional frameless glasses, the frame surrounding the lens does not exist, so it is fixed only by the bridge and the fixed frame. In such a structure, the optical fiber is fastened to both sides of the lens to couple the lens to the fixed frame and the bridge. If the puncturing position of the through hole into which the bolt is inserted is not correctly selected, a gap exists between the side of the lens and the inside of the locking portion, and thus there is a problem that the lens is not firmly coupled between the bridge and the fixing frame.

In addition, if there is a gap between the side of the lens and the engaging portion, if vibration or shock is applied to the frameless glasses during wearing, the lens may be distorted around the fastening bolts along the inside of the engaging portion. If this operation is repeated, there is a problem that the fastening between the fixing bolt and the nut is released.

Meanwhile, in the related art, an insertion hole having a diameter corresponding to the diameter of the fixing bolt is formed in the fixing frame so that the fixing bolt is coupled through the fixing frame. Accordingly, the drilling position of the through hole formed in the lens takes into account the curvature, frequency, and thickness of the lens. Instead, the side of the lens was drilled in a position where it could be pressed against the catch.

Accordingly, when the lens is a thick concave lens, the user's field of view is obscured by the bolts coupled to the through hole of the lens, and when the lens is a thin convex lens, the clamping force of the fixing bolt penetrating the lens is excessive. There was a problem that the lens is broken.

Therefore, in order to solve the above problems, the present invention is a fixed frame and the toothed washer formed in one-way serrated concavities and convexities on opposite surfaces, respectively, to fasten the fixing bolt while pressing the lens in the direction of the engaging portion and at the same time the lens side By arranging the torsion prevention device between the locking part and the locking part, one side of the lens can be tightly fastened to the locking part without any gap between the lens and the locking part, so that the lens is pushed backward by the vibration or shock applied to the frameless glasses during wearing. It is to provide a rimless lens fixing device of the rimless glasses that can prevent the twisting or twisting and further prevent the loosening of the fixing bolt and nut by coupling the lens to the fixed frame with a strong bonding force.

In addition, another object of the present invention is provided with a wedge-shaped washer to prevent the gap between the lens side and the engaging portion is pushed back by the impact or vibration when the lens is coupled to the fixed frame through the fastening means To provide an uneven lens fixing device for frameless glasses, in which a fixed frame and a washer are formed by mutual wedge coupling.

Furthermore, another object of the present invention is to form a long hole in the fixing frame so that the optician can accommodate a wide range of tolerances for the drilling position of the through hole when the through hole of the lens is manually drilled to penetrate the fixing bolt through the lens. Accordingly, to provide a rimless lens fixing device of a frameless glasses that can be tightly fastened to the locking portion without a gap between the side and the locking portion of the lens.

That is, as the long hole 16 is formed, when the lens is a highly concave lens, as shown in FIG. 1C, the drilling position of the through hole 3a is shifted to the outside of the lens 3 to set the fixing bolt 1. It is possible to prevent the user's field of view from being blocked in advance. Furthermore, when the lens is a magnifying glass (convex lens), as shown in FIG. 1D, the perforation position of the through hole 3a is relatively thicker than the outside of the thinner lens as shown in FIG. 1D. By moving to set to prevent the lens from being damaged by the fastening force of the fixing bolt.

As the long hole 16 is formed in the fixed frame 10 as described above, the optician takes the through hole 3a of the lens 3 in consideration of the thickness, the frequency, and the curvature of the lens. By applying a wider range, it is possible to meet the optimum conditions for fixing the lens to the fixed frame.

Accordingly, when the lens 3 is fixed to the fixing frame 17 by the fixing bolt 1 and the nut 4, the lens 3 moves toward the locking portion 13 without any gap between the side of the lens 3 and the locking portion 13. Strongly fastened to prevent the lens 3 from twisting and also to prevent the fixing bolt (1) and the nut (4) from being loosened.
