Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a structure of a spectacle frame,

The present invention relates to an eyeglass frame which is equipped with an iron-core spring at the end of an eyeglass frame to support a rotation pin for rotatably connecting the eyeglass legs and to provide a flexible intermittent feeling when folding or unfolding the eyeglass legs, And a connection structure of an eyeglass frame and a pair of eyeglasses legs which are elastically supported by the spring so as not to require a separate fixing means for fixing the eyeglass legs.

In general, the spectacle frame is composed of a spectacle frame to which a lens is coupled and a spectacle frame foldably coupled to an end piece of the spectacle frame. The spectacle frame and the spectacle frame are made of a synthetic resin material or a thick 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 leg and the end piece of the spectacle frame, 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, the glasses are loosened and the use of the glasses is uncomfortable. 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.

At this time, the rotation pin 30 '' maintains a close contact state with one side of the through hole e '' of the front projection part of the eyeglass leg 2 '' 'due to the elastic force of the spring 20' Quot; is further rotated to move the eyeglass leg 2 '' outward beyond a predetermined angle, the front projection of the eyeglass leg 2 '' 'is moved inward as shown in FIG. 36, The eyelid is brought into close contact with the other side of the through hole e "so that the eyeglass leg is bent backward according to the face shape of the wearer.

Figs. 37 to 44 illustrate a tenth embodiment of the present invention, in which a protruding portion protrudes rearward at the distal end of the spectacle frame 1 '' ', and a concentric circular pivot pin 30 is inserted into the protruding portion, The eyeglass hinge portion 10 '" has an opening on the front end of the eyeglass leg 2' " for inserting a projection of the eyeglass hinge 10 '" And an opening groove 22 communicating with the operating space a " is formed on the outer side surface of the upper surface and the lower surface of the opening h, (40 '"); The upper and lower ends of the eyeglass leg hinge portion 40 '' are supported at the upper and lower ends thereof and the intermediate outer circumferential surface of which the diameter is smaller is spaced apart from the projecting portion through hole e '' 'of the eyeglass frame hinge portion 10' A projecting portion for projecting and protruding from the opening groove 22 is formed in the operating space a '' of the eyeglass leg hinge portion 40 '', Shaped spring 20 "which elastically contacts the projecting portion of the frame 10 '"

39, when the eyeglass leg 2 '' is coupled to the eyeglass frame 1 '', the tip end of the spring 20 '' is connected to the eyeglass frame 10 ' Quot ;, and the rotation pin 30 is in contact with the outer surface of the projecting portion of the projection hinge portion 10 '"of the eyeglass frame hinge portion 40'" ).

When the rotation pin 30 is inserted into the through hole e '' 'having a larger diameter than the rotation hole b' ', the eyeglass frame 10' '' due to the elastic force of the spring 20 ' Quot ;, the rotation pin 30 '' is brought into close contact with the outside of the through hole e '' having a small diameter. ).

On the other hand, when the eyeglass leg 2 '' is started to be folded, the spring 20 '' slides on the edge of the projection of the eyeglass frame hinge 10 '' as shown in FIG. 41 and the spring force of the spring 20 'gradually increases When the eyeglass leg 2 '' is completely folded, the tip end of the spring 20 '' is brought into horizontal contact with the entire projecting portion of the eyeglass frame hinge 10 '' 'as shown in FIG.

On the other hand, when the eyeglass foot 2 '' 'is further rotated to move outside the eyeglass leg 2' 'in a fully extended state, the spring 20 is elastically deformed as shown in FIG. 43, So that the legs of the glasses are bent backward according to the face shape of the eyes.
