Description

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

The present invention relates to a spectacle frame for detachably connecting an eyeglass leg to an end portion of a divided spectacle frame, in which a spectacle frame divided by a hinge piece to which the spectacle leg is connected is connected simply and firmly, And a connection structure of the eyeglass leg.

In general, the frame made of aluminum can not be welded, and even if it is welded, the thickness of the welded part becomes apparently thick, resulting in defects. When the thread groove is formed in aluminum, the thread portion is broken due to the nature of the soft material There is a problem that coupling is not performed.

In order to solve such a problem, as shown in Figs. 1 to 4, the eyeglass frame connecting structure of the prior art eyeglass frame according to the present invention is constructed such that both ends of the eyeglass frame 1 to which the eyeglasses legs are connected are vertically- Is formed to be relatively thin, and the receiving groove (b) is formed relatively deeply in the upper inner surface in the fixing groove (a), and the fixing groove An eyeglass frame end piece 50 formed with a fastening hole c passing through the receiving groove b and fastening the fastening screw 51 to the fastening hole; A lower end portion is inserted into the receiving groove b of the end piece 50 and a screw hole in which a fixing screw 51 is screwed is formed at a lower end portion and a hook is formed at an upper end portion thereof, A hinge piece 60 made of stainless steel; An elastic member 70 in which a hole is formed in an upper plate and a lower plate which are folded and bent in a middle so as to be doubly fitted on the hinge piece 60 and in which the middle of the upper plate is folded multiple times and a protrusion d is formed laterally Respectively.

Here, an operation hole (e) is formed at the distal end portion so that the hinge piece (60) is inserted in the distal end of the eyeglass leg (2), and the rotation pin (41) fitted to the hook of the hinge piece (60) And the rear end of the operating hole e is bent outwardly by a predetermined width and then bent backward to extend rearward.

The hinge piece 60 is inserted into the receiving groove b of the spectacle frame 1 and is fixed to the lower end piece through the fastening hole c of the lower end piece in a state in which the upper and lower end pieces 50 are in close contact with each other. When the screw 51 is inserted and screwed into the screw hole at the lower end of the hinge piece 60, the upper and lower end pieces 50 are tightly adhered to each other. When the lower plate of the elastic member 70 is inserted into the hinge piece 60 The lower plate of the elastic member 70 is inserted into the fixing groove a so that the movement is restricted.

After the upper plate of the elastic member 70 is inserted into the upper end of the hinge piece 60 and then the operation hole e of the connecting part 40 of the eyeglass leg 2 is inserted into the hinge piece 60 protruded above the upper plate, When the rotation pin 41 is hooked on the hook of the piece 60, the eyeglass leg 2 can be rotated about the rotation pin 41. [

In the present invention, when the eyeglass leg 2 is rotated, the elastic force of the interlocking protrusion 42 protruding from both sides of the rotation pin 41 increases rapidly when the elastic member 70 passes the protrusion d of the upper plate The direction of the elastic force acting on the intermittent projection 42 of the eyeglass leg 2 changes as the projection d passes through the projection d so that the folded or unfolded The elastic force acts on the folded or unfolded portion of the eyeglass leg 2 when it passes through the projecting portion d so as to maintain the folded state or the unfolded state of the eyeglass leg 2

The hinge piece 60 is opened toward the front and formed with a groove having a curved shape to form a hook for allowing the rotation pin 41 of the connection part 40 of the eyeglass leg 2 to be hooked.

However, in the conventional eyeglass frame connecting structure of the conventional eyeglass frames, a fastening hole is formed in the bottom surface of the lower part of the divided eyeglass frame to penetrate the receiving groove, and the fastening screw is inserted into the fastening hole, So that the joining structure is too complicated, the disassembly and assembly are troublesome, the productivity is low, and the manufacturing cost is high.

SUMMARY OF THE INVENTION The object of the present invention is to solve the problems described above, and it is an object of the present invention to provide an eyeglass frame which is easy to assemble and disassemble, And to provide a connection structure of a spectacle frame and a pair of eyeglasses bridges.

In order to achieve the above object, the present invention provides a spectacle frame comprising: a spectacle frame on which spectacle lenses are mounted, the spectacle frame having upper and lower end portions and upper and lower engaging portions, An elastic member is fitted to a hinge piece protruding rearward of the eyeglass frame and a tip end of the eyeglass legs elastically adhered to the elastic member is pivoted to the rear end of the hinge piece Which are connected to each other.

In the present invention, since the hinge part is coupled to the spectacle frame divided into two, and the upper and lower ends of the frame are firmly coupled, the structure is simple, so that the assembly and disassembly are easy, and productivity and cost are reduced.
