즉, 일측의 곡면 캠(32)이 외력에 의해 편심된 분할틈(a)으로 이동되는 것을 방지하기 위해 회전구멍(b)에서 선단방향으로 난 분할틈(a)이 내측 쪽으로 편심 된 위치에 형성된다.That is, in order to prevent the curved cam 32 on one side from being moved to the eccentric division gap (a) by external force, the division gap (a) formed from the rotation hole (b) in the tip direction is formed at an eccentric position toward the inside. do.

또한, 안경테(1)는 후방으로 만곡되게 돌출되는 측부에 엔드피스(10)의 선단부가 삽입되는 체결홈(g)이 형성되고, 체결홈(g)의 안쪽에 돌기가 구비되며, 돌출된 측부 하부에 고정나사(11)가 삽입되는 구멍이 형성되어, 체결홈(g)에 삽입되는 엔드피스(10)가 체결구멍(e)을 관통하는 고정나사(11)에 의해 고정되게 된다.In addition, the eyeglass frame (1) is formed with a fastening groove (g) into which the front end of the end piece (10) is inserted on the side protruding to be curved to the rear, a protrusion is provided inside the fastening groove (g), and the protruding side A hole into which the fixing screw 11 is inserted is formed in the lower part, so that the end piece 10 inserted into the fastening groove g is fixed by the fixing screw 11 penetrating the fastening hole e.

한편, 안경테(1)가 메탈로 제조될 경우, 엔드피스(10)가 안경테(1)에 용접에 의해 결합되며, 이때 엔드피스(10)의 체결구멍(e)과 상기 체결구멍(e)을 관통하는 고정나사(11)는 필요치 않게 된다.On the other hand, when the eyeglass frame 1 is made of metal, the end piece 10 is coupled to the eyeglass frame 1 by welding, and at this time, the fastening hole e and the fastening hole e of the end piece 10 are The fixing screw 11 passing through is not required.

경첩부(20)는 안경 다리(2) 폭과 두께보다 큰 원통형으로 형성되어, 외주면 중간의 후방 내측 방향에 일정 각도 폭의 절개부가 내부의 회전부(c)와 연계 형성되며, 상면과 저면에 각기 관통구멍(d) 동심원상으로 확장된 수납홈(h,i)이 형성되고, 관통구멍(d)은 회전부(c)의 아래쪽 내부 폭이 윗쪽보다 작게 형성된다.The hinge portion 20 is formed in a cylindrical shape larger than the width and thickness of the spectacle leg 2, and an incision of a certain angular width in the rear inner direction in the middle of the outer circumferential surface is formed in connection with the inner rotating portion (c), respectively, on the upper and lower surfaces. The through hole (d) is formed concentrically extended receiving grooves (h, i), the through hole (d) is formed in the lower inner width of the rotating portion (c) than the upper side.

또한 경첩부(20)의 상부 수납홈(h)은 각이 진 홈으로 형성되고, 하부의 수납홈(i)은 원형의 홈으로 형성된다. In addition, the upper receiving groove (h) of the hinge portion 20 is formed into an angled groove, and the lower receiving groove (i) is formed into a circular groove.

회전축(30)은 외주면 대칭 부위에 한 쌍의 곡면 캠(32)이 형성되고, 하단 외부면 굵기가 작게 형성되어 단턱(j)이 구비되며, 상단에 경첩부(20)의 수납홈(h) 형태의 머리부가 형성되고, 나사홈에 체결되는 고정볼트(31)는 경첩부(20)의 하부 수납홈(i) 형태의 머리가 형성된다.The rotation shaft 30 has a pair of curved cams 32 formed at a symmetrical portion of the outer circumferential surface, the lower outer surface is formed with a small thickness so that a stepped jaw (j) is provided, and a receiving groove (h) of the hinge 20 at the top A head in the form of a head is formed, and the fixing bolt 31 fastened to the screw groove has a head in the form of a lower receiving groove (i) of the hinge part 20.

한편, 한 쌍이 대칭되게 형성되는 캠(32)은 회전구멍(b) 코너 부위의 곡률에 준하는 곡율로 형성함이 바람직하며, 캠(32)의 반대편 대칭되는 한 쌍은 원형의 완만한 곡면을 형성한다.On the other hand, the cam 32 in which a pair is symmetrically formed is preferably formed with a curvature equivalent to the curvature of the corner of the rotation hole (b), and the pair opposite to the cam 32 forms a circular smooth curved surface. do.

이와 같이 구성되는 본 발명은 먼저 경첩부(20)의 회전부(c)에 엔드피스(10)의 말단부를 삽입시키고, 회전축(30)을 관통구멍(d) 상부에서 삽입시켜 엔드피스(10)의 회전구멍(b)을 관통한 상태에서 관통구멍(d) 하부를 통해 고정볼트(31)를 회전축(30)의 나사홈에 체결하면, 회전축(30)의 머리가 상부 수납홈(h)에 삽입되고 고정볼트(31)의 머리가 하부 수납홈(i)에 기밀하게 삽입된다.The present invention configured as described above first inserts the distal end of the end piece 10 into the rotating part (c) of the hinge part 20, and inserts the rotation shaft 30 from the top of the through hole (d) When the fixing bolt 31 is fastened to the screw groove of the rotating shaft 30 through the lower part of the through hole d while penetrating the rotating hole b, the head of the rotating shaft 30 is inserted into the upper receiving groove h. And the head of the fixing bolt 31 is airtightly inserted into the lower receiving groove (i).

이러한 본 발명은 안경다리(2) 선단의 경첩부(20)가 회전축(30)과 함께 엔드피스(10)의 회전구멍(b)을 중심으로 회전하게 되어, 안경다리(2)가 완전히 펼쳐졌을 때, 도 7에 도시된 바와 같이, 회전축(30)의 대칭 캠(32)이 엔드피스(10) 회전구멍(b)의 내측 코너부에 삽입되어 캠(32)의 미는 힘이 축 방향으로 작용함으로 말미암아 저항력이 극대화 되고, 그로 인해 안경다리(2)가 외측으로 벌어지는 것이 억제되게 된다.In the present invention, the hinge portion 20 of the front end of the temples 2 rotates about the rotation hole b of the end piece 10 together with the rotation shaft 30, so that the temples 2 may be completely unfolded. 7, the symmetric cam 32 of the rotation shaft 30 is inserted into the inner corner of the rotation hole b of the end piece 10 so that the pushing force of the cam 32 acts in the axial direction. As a result, the resistance is maximized, and thereby the temple 2 is suppressed from spreading outward.

또한, 이러한 상태에서 도 8에 도시된 바와 같이, 안경테(1) 안쪽 방향으로 안경 다리(2)에 일정 이상의 힘을 가하면, 회전축(30)의 캠(32)이 마찰 저항을 이기고 엔드피스(10) 회전구멍(b)의 코너에서 벗어나 이동하게 되며, 이때 엔드피스(10)는 분할틈(a)이 벌어지며 캠(32)에 반발하는 힘이 증가하도록 하다가 캠(32)이 상사점을 넘으면 벌어졌던 분할틈(a)이 탄발력에 의해 캠(32)을 미는 힘으로 작용하게 되어, 안경 다리(2)가 저절로 접히도록 한다.In addition, as shown in FIG. 8 in this state, when a certain or more force is applied to the spectacle leg 2 in the inner direction of the spectacle frame 1, the cam 32 of the rotation shaft 30 overcomes the frictional resistance and the end piece 10 ) It moves away from the corner of the rotation hole (b), and at this time, the end piece 10 has a split gap (a) open and the force repelled against the cam 32 increases, and when the cam 32 exceeds the top dead center The split gap (a) that has been opened acts as a force to push the cam 32 by the elastic force, so that the spectacle leg 2 is automatically folded.

또한, 안경 다리(2)가 안경테(1) 쪽으로 완전히 접히면, 도 9에 도시되는 바와 같이, 회전축(30)의 캠(32)이 엔드피스(10) 회전구멍(b)의 내측 코너에 삽입되어 캠(32)의 미는 힘이 다시 축 방향으로 작용함으로 말미암아 저항력이 극대화 되고, 그로 인해 안경다리(2)가 안쪽으로 이동하는 것을 억제하게 된다.In addition, when the glasses leg 2 is completely folded toward the eyeglass frame 1, as shown in FIG. 9, the cam 32 of the rotation shaft 30 is inserted into the inner corner of the rotation hole b of the end piece 10. As a result, the pushing force of the cam 32 acts in the axial direction again, thereby maximizing the resistance force, thereby suppressing the temple 2 from moving inward.

이러한 본 발명은 안경 다리(2)를 접거나 펼칠 때 함께 회전하는 회전축(30)의 캠(32)과 탄력적으로 벌어지거나 복원되는 엔드피스(10) 사이에 반발력 또는 복원력이 작용하여, 저항구간과 자유 낙하구간이 생기므로 단속감을 느끼게 해주고, 완전히 접힌 상태 또는 펼친 상태가 잔류 탄성에 의해 안정된 상태를 유지하도록 한다.In the present invention, a repulsive force or a restoring force acts between the cam 32 of the rotation shaft 30 that rotates together when the spectacle leg 2 is folded or unfolded and the end piece 10 that is elastically opened or restored, and the resistance section and Since there is a free fall section, it makes a sense of intermittent feeling, and the fully folded or unfolded state maintains a stable state by residual elasticity.
