Abstract

PURPOSE: A join structure of a plastic rimless glasses lens and temples are provided to drastically improve the durability by increasing the ability of fixing with only one assembly. CONSTITUTION: A join structure of a plastic rimless glasses lens and temples includes a bolt and a fixing nut(5). The bolt is provided with a lens pushing unit(3a), wherein the width of the lens pushing unit(3a) becomes narrow as the portion of the lens pushing unit(3a) goes to the point contacting to the lens. And, the bolt and the fixing nut(5) are connected through the connecting hole(7a).

Description

The join structure of plastic rimless glasses lens and bow on a pair of spectacles}

The present invention relates to a structure of a coupler that directly inserts a hole in the plastic lens in order to couple the house (bent) to the plastic frameless glasses.

The rimless glasses are fixed by a pair of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of lenses attached to one side of each lens, with the fixed frame surrounding the pair of lenses removed. It is much lighter because it can be made and worn freely according to the face shape of the face, and it is much lighter because only the lens is worn. to be.

However, normal rimless glasses cannot be used for a long time due to the unstable connection between the glasses legs and the lens, or the whole or part of the glasses can easily be distorted. In addition to the problem of causing eye fatigue and at the same time deteriorating vision, there was also a problem of lowering the assembly productivity of the rimless glasses.

The above problems are caused by the failure to puncture the pair of lenses in the exact symmetrical position of the rimless eyeglass lens, or by using ordinary bolts and nuts for assembling the rimless eyeglasses and glasses legs. This is because bolts and nuts are not long enough to loosen the bolts and nuts so that the fixing force is reduced.

Therefore, the development of the coupling bolt and nut dedicated to the rimless glasses to maintain the complete bonding force for a long time in assembling the glasses legs and the house (bent) in the rimless glasses lenses are urgently required.

In the present invention, in order to solve the above problems, the coupling bolt (3) can be fastened to the plastic frameless glasses most suitable,

When assembling the lens and the bent part, the lens press part 3a is made at the part where the lens 7 and the coupling bolt 3 come into contact with each other. The invention was conceived with the technical object of the present invention in constructing the bolt 3 and the nut 5-the lens 7 so as to be in close contact and exhibit excellent fixing force.

1 is a perspective view and a partially enlarged view of the present invention, Figure 2 is a coupling plan view of the present invention, Figure 3 is an exploded and bonded plan view of the coupling portion of the present invention, Figure 4 is a coupling state of the bolt and nut of the present invention When showing the cross-sectional view of the present invention in detail as follows.

Referring to the process of assembling the plastic rimless glasses of the present invention and the leg portion of the invention with reference to Figures 1 and 2, for example,

A pair of plastic spectacle lenses 7 is used to drill a coupling hole 7a so as to be symmetrical at both same positions. At this time, the length of the coupling bolt 3 is determined according to the diameter of the coupling hole 7a.

Then, after joining the welding bolt (bent portion, the intermediate connecting portion of the spectacle lens and the spectacles) (1) to the central portion of the coupling bolt (3), and constitutes the spectacles (9). In the drawings of the present invention is represented as an illustrative example of a leg with a hinge (9a) configured.

Finally, a pair of spectacle lenses (3)-a cast iron (bending part) (1)-a hinge (9a)-a pair of spectacles (6a) and a pair of spectacle lenses with a coupling hole (7a) are fitted. ) Is passed through the coupling hole 7a and tightly tightened with the nut 5 to complete the assembly process.

Of course, if there is no problem in the coupling, the order of coupling can be changed and applied.

As shown in Figure 2, 3, the coupling bolt (3) of the present invention has a different form from the general bolt, by making the lens pressing portion (3a) protruding in an annular shape inside the bolt head, the coupling bolt (3)-The spectacle lens 7-When the nut 5 is engaged, the sharp and narrow lens pressing portion 3a is embedded in the spectacle lens 7 so as to have a complete fixing force and to sufficiently prevent the warping phenomenon. It becomes possible. The lens pressing portion 3a is configured to sharply protrude from the portion in contact with the lens 7, so that the cut surface is almost close to a triangle.

The protruding lens pressing portion 3a is fixed to the lens 7 to achieve perfect coupling, wherein the material of the lens pressing portion 3a is the same metal as that of the general bolt and the lens 7 is a plastic lens. As the plastic has elasticity and the support force is strong even when a force is applied to a specific part, such a combination is possible.

In general, plastic lenses are light and hardly broken, so they are suitable for active athletes, and plastic eyeglass lenses that are functionally used for various sports are continuously appearing one after another.

In addition, the plastic coupling bolt 3 of the frameless glasses of the present invention can be used by modifying the lens pressing portion (3a) in various forms. For example, the shape of the circular pressing portion may be oval, triangle, square, pentagon,... You can also use it.

As described above, through the plastic frameless eyeglass lens household (bent portion) coupler of the present invention,

Compared to the existing Ute glasses, it is lighter and has no eyeglass frames, so the field of view is wider.

It is possible to solve the fact that the assembly bolt is distorted due to the high binding force and the lens focus is deformed, which can not be used for a long time. It is said that the invention has a great effect such that the fixing ability is increased by one more assembly, and the durability is greatly improved, the safety is improved, and the assembly productivity is improved.
