이하, 상기 볼베어링과 탄성부재의 결합 및 작용을 살펴본다.Hereinafter, look at the coupling and action of the ball bearing and the elastic member.

상기와 같은 구성으로, 상기 볼베어링의 제 1베어링 회전판의 볼구름부(431)가 구 형상의 볼(440)을 지지하면서 볼구름부(431)의 맞은편 타단은 상기 회전부재의 몸체부(220) 내측 일단에 고정되고, 다수의 볼지지홀(422)에 구 형상의 볼(440)이 결합된 상기 리테이너(420)가 상기 제 1베어링 회전판의 볼구름부(431)에 결합된다.In the configuration as described above, while the ball cloud portion 431 of the first bearing rotating plate of the ball bearing supports the spherical ball 440, the other end opposite to the ball cloud portion 431 is the body portion 220 of the rotating member The retainer 420 is fixed to the inner one end, the ball 440 of the spherical shape is coupled to the plurality of ball support holes 422 is coupled to the ball cloud portion 431 of the first bearing rotating plate.

또한, 상기 제 2베어링 회전판(410)이 상기 리테이너의 고정부(423)에 끼워져 상기 구 형상의 볼(440)을 지지하고, 상기 탄성부재의 끝단(310)이 상기 제 2베어링 회전판(410)의 위에 안착하게 된다.In addition, the second bearing rotary plate 410 is fitted to the fixing portion 423 of the retainer to support the spherical ball 440, the end 310 of the elastic member is the second bearing rotary plate 410 Settled on top of

이 때, 상기 탄성부재(300)의 내경은 상기 리테이너의 고정부(423)에 끼워지게 되어 상기 탄성부재(300)의 편심을 방지하게 된다.At this time, the inner diameter of the elastic member 300 is fitted to the fixing portion 423 of the retainer to prevent the eccentricity of the elastic member 300.

이러한 힌지조립체의 작동과정을 살펴보면, 상기 회전부재(200)가 회전하여 고정부재(100)에 대해 축방향으로 이격되면 결과적으로 탄성부재(300)가 압축되고, 이에 따라 상기 회전부재(200)의 이동은 제한되며, 상기 회전부재(200)의 이동이 제한됨으로써 도어(도 1참조,20)는 서서히 닫히게 된다. Looking at the operation of the hinge assembly, when the rotating member 200 is rotated and spaced apart in the axial direction with respect to the fixing member 100, the elastic member 300 is consequently compressed, and accordingly of the rotating member 200 The movement is limited, the door (see Fig. 1, 20) is gradually closed by the movement of the rotating member 200 is limited.

상기 도어의 개폐작동에 따라 상기 힌지조립체의 회전부재(200)가 회전함으로써 상기 탄성부재(300)는 인장/압축되며, 이 과정에서 상기 탄성부재 끝단(310)의 비틀림에 의한 위치 이동으로 상기 회전부재(200)의 몸체부 내측과 맞닿은 탄성부재 끝단(310)의 마찰에 의해 마찰음이 발생하게 된다. As the rotating member 200 of the hinge assembly rotates according to the opening and closing operation of the door, the elastic member 300 is tensioned / compressed, and in this process, the elastic member 300 is rotated by the positional movement of the elastic member end 310 by twisting. The friction sound is generated by the friction of the elastic member end 310 in contact with the inner side of the body portion of the member 200.

이러한 마찰음은 상기 회전부재의 내측 일단과 탄성부재의 끝단 사이에 구비되는 상기 볼베어링을 삽입함으로써, 상기 탄성부재 끝단의 움직임은 상기 볼베어링의 제 2베어링 회전판에 전달되고 상기 리테이너의 볼지지부에 구성된 볼이 움직이게되어, 탄성부재의 끝단과 회전부재 내측 일단의 접촉부위에서의 직접적인 마찰을 방지하여 마찰소음을 제거할 수 있다.The friction sound is inserted into the ball bearing provided between the inner end of the rotating member and the end of the elastic member, the movement of the end of the elastic member is transmitted to the second bearing rotating plate of the ball bearing and the ball configured in the ball support portion of the retainer By moving, the friction noise can be removed by preventing direct friction at the contact portion between the end of the elastic member and the inner end of the rotating member.

상술한 바와 같이 본 발명에 의하면, 상기 회전부재의 몸체부 내측 일단과 상기 탄성부재 끝단 사이에 볼베어링을 구비함으로써, 상기 회전부재의 회전에 따른 탄성부재 끝단의 비틀림에 의한 위치 이동으로 상기 회전부재의 몸체부 내측과 맞닿은 탄성부재 끝단의 마찰에 의해 발생하는 마찰음을 제거할 수 있다.According to the present invention as described above, by providing a ball bearing between the inner end of the body portion of the rotating member and the end of the elastic member, by the positional movement of the end of the elastic member according to the rotation of the rotating member of the rotating member The friction sound generated by the friction of the end of the elastic member in contact with the inside of the body portion can be removed.
