Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a spectacle frame,

The present invention is characterized in that a plate spring is integrally provided at the tip of a spectacle leg rotatably connected to the end of an eyeglass frame so that the eyeglass legs are folded or unfolded flexibly or flexibly and rapidly folded or unfolded, To a spectacle frame connecting structure of a spectacle frame.

Generally, the eyeglass frame is composed of an eyeglass frame to which a lens is coupled and an eyeglass frame foldably coupled to an end piece of the eyeglass frame. The eyeglass frame and the eyeglass frame are made of a synthetic resin material or a metal material.

The glasses legs are configured to be folded or unfolded through a hinge provided on the spectacle frame. When the spectacles are worn, the spectacle legs are stretched. When the glasses are stored, the spectacle legs are folded to reduce the volume.

The hinge includes a hinge member, which is welded to the eyepiece and the end piece of the spectacle frame, respectively, and a hinge screw that not only joins the hinge member but also allows the eyeglass leg to be folded.

However, when the hinge is used for a long period of time, the hinge screw is loosened when the glasses are used for a long time. Therefore, it is inconvenient to use the glasses because the legs are loosened. Also, in order to replace the glasses legs, There was this uncomfortable problem.

Further, since the hinge member is joined to the end piece of the spectacle frame and the spectacle frame by welding, there is a problem in that the structure is complicated, the fabrication of glasses is troublesome, and the defect is often caused by the breakage of the welded portion.

KR Patent No. 10-1237838

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an eyeglass frame which can be easily folded and folded, And which is easy to disassemble and assemble so that the folded state and the unfolded state can be firmly maintained.

In order to achieve the above object, the present invention provides an eyeglass frame which is formed on both sides of a general eyeglass frame provided with a lens and which is bent and extended rearwardly, the upper and lower ends of which are formed by bending inward, A hinge portion having a first rotating portion and a second rotating portion; A guide pin having both ends of a pin shape rotatably fitted to the first rotation part of the hinge part and having a body larger than both end parts of the pin shape; A rotary pin is formed so as to be upwardly and downwardly projected from the upper end of the tip portion so as to be rotatably fitted to the upper and lower second rotary portions of the hinge portion, the middle portion of the tip end is divided by a predetermined length along the axial direction, And the eyeglass leg having a double refraction portion at the tip end of the leaf spring to be elastically brought into close contact with the outer circumferential surface.

In the present invention, since the leaf spring integrally formed on the eyeglass leg moves along the guide pin and changes the direction and magnitude of the elastic force about one pole, the eyeglass legs are not folded or unfolded rapidly, It has the advantage that it is easy to disassemble and assemble because it has a simple structure so that it does not have a hinge screw and welded part.

9 is an exploded perspective view showing still another embodiment of the present invention.

As shown in Figs. 1 to 6, the present invention is formed in a region that is extended from both sides of a general eyeglass frame 1 to which a lens is fitted, and each of the upper and lower ends of the end portion is bent inward A hinge portion 10 having a first rotating portion a and a second rotating portion b formed symmetrically up and down, respectively; A guide pin 20 whose both ends of the pin are rotatably fitted to the first rotating portion a of the hinge portion 10 and whose outer diameter is larger than both end portions of the pin shape; A rotary pin 31 protruding upwardly or downwardly from the top and the bottom respectively so as to be rotatably fitted in the upper and lower second rotary parts b of the hinge part 10 is formed and the middle part of the tip end is divided by a predetermined length And the eyeglass leg 30 having the leaf spring 32 and the double refraction portion c formed at the tip end of the leaf spring 32 elastically brought into close contact with the outer circumferential surface of the guide pin 20, The basic features of the configuration.

Here, the tip portion of the eyeglass leg 30 is divided into an upper portion and a lower portion, each of which is refracted inward and then refracted backward so that a jaw portion formed by the refraction is caught by the end portion of the hinge portion 10, And a rotation pin (31) protrudes downward from the top end of the lower portion.

The leaf spring 32 is elastically deformable with an elastic force between the upper portion and the lower portion of the distal end of the eyeglass leg 30, and the distal end portion of the leaf spring 32 is bent to a certain width inward, the outer circumferential surface of the guide pin 20 is brought into surface contact with the outer circumferential surface (c), and the tip end thereof is curved.

On the other hand, the hinge part 10 is formed with a hole of the second rotation part b near the inner surface of the rear extension part of the eyeglass frame 1, and has a first rotation part a And the pins at both ends of the guide pin 20 are moved in the horizontal direction to the first rotation part a, And is rotatably fitted.

3, when the eyeglass leg 30 is unfolded, the jaw portion due to the refraction of the upper and lower tip portions is caught by the end portion of the hinge portion 10, And the tip end of the leaf spring 32 is brought into contact with the outer circumferential surface of the guide pin 20. At this time, the elastic force acting on the outer circumferential surface of the guide pin 20 exceeds the pole point, The tip end of the leaf spring 32 pushes the guide pin 20 so as to push the guide pin 20 in the first rotation part a ) Is firmly fixed.

When the eyeglass leg 30 is stretched and the eyeglass leg 30 is folded inward, a rotational force of at least a predetermined level is applied to the inside of the eyeglass leg 30 so that the tip of the plate spring 32 overcomes the reaction force And the eyeglass leg 30 is rotated in the inward direction and the front end of the leaf spring 32 is rotated in the inward direction, Of the guide pin (20) is in contact with the outer circumferential surface of the guide pin (20), the movement is suppressed by the abruptly increased frictional force, and the folded state is maintained.

That is to say, when the spectacle leg 30 is brought into surface contact with the opposite direction of the polar point so that the spectacle leg 30 is folded abruptly and the refraction portion c of the tip end of the leaf spring 32 comes into contact with the outer peripheral surface of the guide pin 20 The movement is suppressed by the abruptly increased frictional force and the folded state is maintained.

6, when the rotational force is exerted to the outer side of the eyeglass leg 30 in order to unfold the eyeglass leg 30, the elastic force of the eyeglass leg 30 expands suddenly, 30 of the eyeglass legs 30 are opened and the eyeglass legs 30 are held in the unfolded state.

7 and 8 illustrate another embodiment of the present invention in which the tip of the leaf spring 32 'of the eyeglass leg 30 is formed as a straight line without bending and the rear end of the eyeglass frame 1, A receiving groove (d) is provided in the extended portion.

9 shows another embodiment of the present invention in which the first rotating part a 'of the hinge part 10 to which the guide pin 20 is coupled is formed to open to the outside, .
