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 and a connection structure of a pair of eyeglasses frames, which can simplify the connection structure of the eyeglass legs elastically and foldably connected to the end of the eyeglass frame to reduce the production cost while improving productivity.

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.

In addition, since the hinge member is joined to the end piece of the spectacle frame and the spectacle frame by welding, there is a problem that the manufacture of the spectacles is troublesome and the defect is often caused by the breakage of the welding site.

It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a spectacle frame which can easily attach and detach a spectacle leg to a spectacle frame without having a welded portion on the spectacle frame and the spectacle frame, and without using a separate hinge screw, The present invention provides a connection structure of an eyeglass frame and a pair of eyeglasses frames, which is easy to assemble, and which allows the operation and folding motion of the eyeglass legs to be interrupted by elasticity,

In order to achieve the above object, according to the present invention, hooks are projected on an upper portion and a lower portion with a predetermined gap in the middle of an end plate end extending rearward from both sides of the spectacle frame, A hinge part protruding from the hinge part; A front end of the eyeglass leg being formed rearwardly of the receiving groove and having upper and lower hooks formed on the upper and lower sides of the receiving groove so that the upper and lower hooks of the hinge are fitted into the upper and lower hooks; And a plate spring in which a rear end portion is inserted and fixed in the eyeglass leg distal end receiving groove and whose distal end portion is sandwiched between the hooks of the hinge portion.

The present invention is advantageous in that the plate spring is slightly pushed inwardly and the hooks of the end plate are inserted into the hooks of the end portions of the eyeglass legs, so that the assembly is simple and the construction is simple, and the productivity is high and the manufacturing cost is low.

13 is an exploded perspective view of an embodiment in which the hooking protrusion of the hinge portion of the present invention is formed in a circular cross-sectional shape.

1 to 7, a hinge part is formed at an end of an end plate 10 bent and extended from both sides of the eyeglass frame 1, and a spectacle leg 30 having a leaf spring 20, The tip end portion is rotatably coupled to the hinge portion and the leaf spring 20 is resiliently attached to the hinge portion of the end plate 10 as a basic feature of the technical construction.

The hinge portion of the end plate 10 has a hook 11 protruded rearward at upper and lower portions with a predetermined gap in the middle of the end of the end plate 10, The bosses 12 serving as bearings are fitted to the projections of the upper and lower hooks 11 by projecting the projections downward at the ends of the upper and lower hooks 11.

The front end of the eyeglass leg 30 is formed to be relatively thicker than the rear end so that the front end opening of the receiving groove a is rearwardly formed to a predetermined depth and the screw hole b communicating with the rear inner side of the receiving groove a, And a guide groove c is formed between both the cornering jaws 31 so that the inside and the front of the guide groove are opened. And the upper and lower hooks 11 of the end plate 10 are fixed to the fixing screws 32 inserted into the screw holes b after the rear end of the leaf spring 20 is inserted into the receiving groove a, And the leading end portion of the leaf spring 20 is elastically bent between the guide grooves c and is positioned between the upper and lower hooks 11 of the hinge portion.

The hooking jaw 31 protrudes from the inner side of the eyeglass leg 30 in front of the opened receiving groove a and a jaw protruding from a mouth of the receiving groove a to a predetermined space, And a curved recess (e) is formed on the inner surface of the eyeglass leg (20) inside the frame so that the projections of the hook (11) are formed between the edges And a part of the outer circumferential surface of the projection or bush 12 is inserted into the groove e.

The plate spring 20 is bent slightly at its tip end and is formed with a bent portion at its rear end and a screw hole b is formed at the rear end thereof so that the rear end thereof is inserted into the receiving groove a of the spectacle foot 30, the fixing screw 32 is fastened.

Here, the bent portion is formed in the middle of the leaf spring 20, so that the biasing force of the leaf spring 20 is maximized.

The upper and lower hooks 11 of the hinge portion of the end plate 10 having the bush 12 inserted therein are inserted into the inner side hooking jaws 31 of the eyeglass legs 30 to suppress the forward, The distal end portion of the leaf spring 20 elastically urges the inner surface of the distal end portion of the hinge portion so that the eyeglass leg 30 is not separated and can be rotationally moved about the bush 12 inserted in the upper and lower grooves e, The elastic force is changed according to the rotation angle of the eyeglass legs 30. When the eyeglass legs 30 are rotated by a predetermined angle or more, the upper and lower hooks 11 are opened, State.

Here, the receiving groove (a) of the eyeglass leg 30 has an inclined supporting surface (d) for supporting the bottom end of the rear end of the leaf spring (20) at the inner rear end, The inner wall of the receiving groove (a) to which the outer surface of the receiving groove (a) 20 is contacted is expanded toward the front side.

The eyeglass leg 30 receiving groove a is formed to have a wider width on the distal end side so that the elastic force of the leaf spring 20 that is levitated between the upper and lower hooks 11 of the hinge portion of the end plate 10 is maximized.

As shown in Figs. 8, 9, 12 and 13, the hinge portion is provided with a flange 13 protruding inwardly between the ends of the upper and lower hooks 11, So that the tip end of the elastic member 20 can be elastically supported on the upper surface of the flange 13.

10 to 12, the leaf spring 20 is formed in a slightly bent and straight shape at its tip end, and a screw hole b is formed at a rear end thereof, The fixing screw 32 is fastened to the screw hole b after being inserted into the receiving groove a and the bent end of the leaf spring 20 is buried between the upper and lower hooks 11 of the hinge portion, Can be mounted on the upper surface of the flange 13.

13, the hook 11 of the hinge portion is formed in a shape having a circular cross section so that the protrusion of the hook 11 is sandwiched between the rim of the hooking jaw 31, A part of the outer peripheral surface of the projection may be inserted into the groove (e).
