Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the attached drawings.

Referring to Figures 1 to 7, the present invention is fastened by combining the spectacle frame (1) and the temple (2) and can function as an elastic hinge, allowing the assembly of the eyeglass frame (1) and the temple (2) with a simple operation. In order to facilitate replacement and to ensure that the temples (2) are firmly coupled to the glasses frame (1), they may be composed of a connecting portion (10), a fixing portion (20), and a supporting portion (30).

The connecting portion 10 is coupled to the side of the eyeglass frame 1 and can be rotatably coupled to the temple 2. When the connecting portion 10 is combined with the temple 2, it can easily support the temple 2. One side of the connection portion 10 may be bent at a predetermined angle, and the other side may be formed in a square shape. At this time, the other side of the connection part 10 is not limited to a square shape, but may be formed in a circular shape, a polygonal shape, or a shape in which a circular shape and a polygon are combined.

Additionally, the connection part 10 includes a connection bar 11 and a bracket 12.

One side of the connecting bar 11 may be coupled to the side of the eyeglass frame 1. For example, the connecting bar 11 may be formed in a bar or plate shape. The connecting bar 11 has a certain length and may have one side bent at a predetermined angle.

In this case, the connecting bar 11 may be coupled to the side of the eyeglasses frame 1 with one side bent at a predetermined angle, and the other side may be at a right angle to the eyeglasses frame 1.

The bracket 12 may be formed to protrude from the other side of the connecting bar 11. For example, the bracket 12 may be formed in a square shape. An insertion groove 121 may be formed on the inside of the bracket 12 so that the fixing part 20 can be inserted, and a coupling groove 122 may be formed on one side so that the support part 30 can be inserted.

Here, the insertion groove 121 is formed to penetrate the upper and lower surfaces of the bracket 12, and the coupling groove 122 is formed to penetrate inward from one side of the bracket 12 and communicate with the insertion groove 121. You can.

The fixing part 20 may be inserted into and fixed to the inside of the bracket 12. The fixing part 20 is formed in a shape corresponding to the insertion groove 121 of the bracket 12 and can be inserted into the insertion groove 121. At this time, the fixing part 20 may be coupled to the support part 30 when the support part 30 is inserted into the coupling groove 122 of the connection part 10 while being inserted into the insertion groove 121.

At this time, the fixing part 20 includes a fixing bar 21 and a fixing piece 22.

The fixing bar 21 may be formed in the shape of a pillar with a certain length. The fixing bar 21 may be formed to have a diameter smaller than the diameter of the insertion groove 121 of the bracket 12. The fixing bar 21 may be formed, for example, in the shape of a square pillar, but is not limited thereto, and may of course be formed in a triangular, circular, oval, polygonal, or combination of a circular and polygonal shape.

In this case, the fixing bar 21 is inserted into the insertion groove 121, and the support part 30 is coupled to the outside, so that each corner can be formed in a round shape so that it can rotate smoothly and stop at a specific angle.

The fixing pieces 22 may be formed at both ends of the fixing bar 21 to correspond to each other. The fixing piece 22 may be formed to have a diameter larger than the diameter of the fixing bar 21, and its shape may be formed to correspond to the insertion groove 121 of the connecting portion 10.

In addition, when the insertion groove 121 of the connecting portion 10 is formed in an angular shape such as a triangle, square, or polygon, the fixing piece 22 is inserted into the insertion groove 121 when formed in a corresponding shape and diameter. It can be fixed without rotating in the turned state.

Accordingly, the fixing part 20 functions as a hinge to be rotatably coupled to the support part 30 inserted into the coupling groove 122 of the bracket 12 while being inserted into the insertion groove 121 of the bracket 12. It is to carry out.

The support portion 30 is coupled to the temples 2, and the temples 2 can be rotatably coupled to the temples 1. The support part 30 maintains elasticity and can be rotatably coupled to the side of the connection part 10.

At this time, the support portion 30 includes a support piece 31, a locking protrusion 33, a curved portion 34, and a protrusion 35.

One side of the support piece 31 is inserted into the side of the connection portion 10 and can be rotatably coupled to the fixing portion 20. The temple of glasses 2 may be coupled to the other side of the support piece 31. One side of the support piece 31 is inserted into the side of the connection part 10 and then coupled to the outside of the fixing part 20 so that it can rotate based on the fixing part 20.

More specifically, the support pieces 31 are composed of a pair so that one side is spaced apart at a certain interval and corresponds to each other, and the other side may be coupled to each other in close contact. As one side of the pair of support pieces 31 is spaced apart from each other, a space 32 may be formed therebetween. Here, the separation space 32 may be formed by extending a certain length from one side of the support piece 31 to the other side, that is, in the longitudinal direction of the support piece 31.

Here, the elastic force is increased at the end of the separation space 32 in the direction in contact with the temple of glasses 2, and the separation space 32 is cut due to the accumulation of destruction fatigue due to repeated separation and restoration and an instantaneous external impact. The surface is widened and finished with a circular hole to prevent destruction.

In addition, the pair of support pieces 31 as described above can move flexibly so that one side of each can be opened relative to the other side and then restored to its original shape when the external force disappears. In addition, when the pair of support pieces 31 are inserted into the coupling groove 122 of the bracket 12 so that the fixing bar 21 is positioned in the space 32, the pair of support pieces 31 elastically support both sides of the fixing bar 21. can do.

At this time, the pair of support pieces 31 may be bent at a predetermined angle to form a locking protrusion 33. The locking protrusion 33 may be formed by bending one end of a pair of support pieces 31 so that each end approaches each other. When a pair of support pieces 31 support both sides of the fixing part 21, the binding force of the locking protrusion 33 can be further improved as the outer surface of the fixing bar 21 comes into contact with the inner surface. .

That is, when the pair of support pieces 31 support both sides of the fixing bar 21, they are easily separated from the fixing bar 21 by being caught by the locking protrusion 33. It can be prevented.

Additionally, a curved portion 34 may be formed on one side of the support piece 31 in a shape corresponding to the outside of the fixing portion 20.

The curved portion 34 may be formed by being drawn inward from one side of the support piece 31. The curved portion 34 may be formed in a shape corresponding to the outer surface of the fixing bar 21 of the fixing portion 20. When the support pieces 31 are composed of a pair, the curved portions 34 may be formed to correspond to each other on one side of each support piece 31.

More specifically, the curved portion 34 is a first curved portion 341 that is curved and extended toward the inside of the support piece 31, and a curved surface formed by extending parallel to the temples 2 from the first curved portion 311 ( 342) and a second curved portion 343 extending from the curved surface 342 in one direction of the support piece 31.

Additionally, the first curved portion 341 and the second curved portion 343 may be formed to correspond to each other on both sides of the curved surface 342. For example, the first curved portion 341 and the second curved portion 343 may have a specific curvature and be formed in a round shape. Here, the curved surface 342 is illustrated as extending parallel to the temples 2, but is not limited thereto.

Here, when the pair of support pieces 31 support both sides of the fixing part 20, both sides of the fixing bar 21 located on the space 32 are supported by the pair of support pieces 31, respectively. It is inserted into the curved part 34, and the side surface of the fixing bar 21 is in contact with the curved surface 342, and the corner portion is in contact with each of the first curved part 341 and the second curved part 332, so that the supporting force is Let this improve.

Additionally, a protrusion 35 may be formed on the other side of the support piece 31 to improve the strength of the support piece 31.

The protrusion 35 may be formed to protrude from the other side of the support piece 31. The protrusion 35 may have a certain curvature and a round shape. For example, the protrusion 35 may be formed to have the same curvature as the locking protrusion 33.

The protrusions 35 may be formed in plural numbers at regular intervals on the other side of the support piece 31.

In particular, when the protrusion 35 is formed on the other side of the support piece 31, it is formed to protrude at a position corresponding to the curved portion 34 of the support piece 31, and is arranged at regular intervals based on that position. It can be provided in as many as possible.

As these protrusions 35 are formed to correspond to the other sides of each of the pair of support pieces 31, a curved portion 34 is formed to reduce the strength that is reduced due to a reduction in the thickness or width of the support pieces 31. It can be reinforced.

In addition, when the pair of support pieces 31 are coupled to the fixed bar 21 or rotated based on the fixed bar 21, one side of the pair of support pieces 31 is damaged in the process of opening and closing. Durability can be improved to prevent this.

Accordingly, in the process of inserting the fixing part 20 into the insertion groove 121 of the bracket 12, the support part (20) is positioned in the space 32 between the pair of support pieces 31. When 30) is inserted into the coupling groove 122 of the bracket 12, both sides of the fixing bar 21 are inserted from the pair of support pieces 31 into each curved portion 34, so that the support portion 30 is made to be coupled to the outside of the fixing part 20.

In this case, since the pair of support pieces 31 elastically support both sides of the fixed bar 21, they can rotate around the fixed bar 21.

In particular, when the support part 30 rotates around the fixing part 20 by an external force, the contact between the side of the fixing bar 21 and the curved surface 342 is released, and the first curved part 341 is separated from the curved part 34. ) and the edge portion of the fixing bar 21 located in each of the second curved portions 343 may slide along the surfaces of the first curved portion 341, the curved surface 342, and the second curved portion 343, respectively.

In addition, while the edge of the fixing bar 21 passes through the curved surface 342, the pair of support pieces 31 are each spread outward and the elasticity is maximized. Then, the accumulated elasticity is reversed, causing the elastic restoring force to shrink. As it works, rotation can continue automatically and naturally.

At this time, while the pair of support pieces 31 rotate around the fixing bar 21, both sides of the fixing bar 21 are again inserted into each of the pair of support pieces 31 as curved portions 34, When the side surface of the fixing bar 21 comes into contact with the curved surface 342, the rotation can be stopped.

Therefore, in the process of rotating relative to the fixing part 20, the support part 30 is stopped at each point when both sides of the fixing bar 21 are inserted and contacted with each curved part 34 of the support piece 31. (30) stops rotating at each specific angle, so that step-by-step rotation can be easily performed.

Here, the fixing bar 21 of the fixing part 20 is formed in a polygonal shape, so that as the angled surface increases, the rotation angle of the support part 30 can become more diverse.

The coupling structure of the temples as described above combines the support part 30 with the connection part 10 in a state where the connection part 1 is coupled to the side of the eyeglass frame 1 in order to couple the eyeglass frame 1 and the temple 2. By doing so, the temples 2 can be easily rotated through the support portion 30.

In particular, when unfolding the folded temples 2 to wear glasses, the rotation angle of the temples 2 can be easily adjusted regardless of the size of the user's head, thereby providing the user with a more convenient wearing experience.

In addition, the combination structure of the spectacle frame (1) and the temple (2) is simplified to the connection part (10), the fixing part (20), and the support part (30), so that the frame (1) and the temple (2) can be assembled with a simple operation. It is possible to facilitate replacement and maintain a more solid connection between the spectacle frame (1) and the temple (2) so that it is not easily separated even when the temple (2) is repeatedly folded.

An eyeglass frame to which the above-mentioned eyeglass temple coupling structure is applied is provided as shown in Figures 9 and 10.

At this time, the structure of the spectacle frame is not limited to the illustration and description as an example, and any spectacle frame to which the hinge structure coupling structure is applied can be used.
