본 고안은 의자에 사람이 앉아 등판을 임의의 각도로 조절가능하게 사용할 수 있는 각도 조절장치에 관한 것으로, 특히 작동레버로 손쉽게 작동하여 등판의 임의의 각도로 조절가능토록 할수 있게 한 의자 등판의 각도 조절장치에 관한 것이다.The present invention relates to an angle adjuster that allows a person to sit on a chair and adjust the backrest to an arbitrary angle. In particular, the angle of the backrest of a chair made to be easily adjusted to an arbitrary angle of the backplate by easily operating with an operating lever. It relates to a control device.
일반적인 의자 등판의 각도 조절장치는 조절 각도가 대체로 등판이 90°내에서 3단계로 한정되어 있고 제한된 각도에 있는 등판을 다시 조절할때에는 등판을 좌판 앞쪽으로 당긴 다음 뒤쪽으로 밀어서 다시 좌판 앞쪽으로 당겨서 제한된 각도에 맞추어 사용하므로 등판을 임의의 각도로 선택할 수 없는 결함 때문에 등판이 뒤로 기울어져도 제한된 각도로 인하여 임의의 각도로 조절할 수 없으므로 안락한 휴식을 취할 수 없어 많은 불편이 뒤따랐다.In general, the angle adjuster of the chair's back is generally limited to three levels within 90 ° of the adjustment angle.When adjusting the back at a limited angle, the back can be pulled toward the front of the seat and then pushed backwards to the front of the seat. Due to the defect that can not be selected at any angle, even if the back is inclined backwards can not be adjusted to any angle due to the limited angle, it was unable to take a comfortable rest, followed by a lot of inconvenience.
본 고안은 이와 같은 결점을 시정하기 위하여 고안한 것으로 등판이180°내에서 임의의 위치에 각도를 선택할 수 있으며, 등판을 좌판 앞쪽으로 당긴 다음 다시 각도를 조절하는 번거로움이 없도록 한 것으로서, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was devised to correct such defects, and the back plate can select an angle at any position within 180 °, and there is no hassle of pulling the back plate to the front of the seat and then adjusting the angle again. When described in detail with reference to the drawings as follows.
의자(1)의 등판(3)과 좌판(3')의 연결부위에 각도 조절기(2)를 부착 형성함에 있어서, 좌판(3')의 양측 모서리에 위치되는 좌판 지지봉(7")과 일체로 형성된 기어박스(7)를 착설하여 기어박스(7) 측면 가운데부의 좌우측판을 연결봉(6")이 통과할 수 있도록 구멍을 내어 연결봉(6")을 관통시키고, 좌판(3')의 반대쪽 모서리에 설치된 동일한 기어박스(7)와 상기 연결봉(6")을 서로 연결하고, 등판지지봉(4')과 기어박스(7)의 측면단부를 관통하여 결합된 축에는 고정홈(7')을 형성하며, 기어박스(7)의 내부에는 회전기어(4)가 회전하여 각도를 조절할수 있게 설치된 등판지지봉(4')과 걸림턱(4")을 형성하여 판스프링(8)을 고정홈(7')과 걸림턱(4")에 탄성을 갖도록 끼우고 고정기어(5)가 코일스프링(9)에 의해 항상 회전기어(4)와 교합되게 하되 고정기어(5)가 레버(6)에 형성된 지지돌기(6')에 의해 착탈되도록 하여서 된 것이다.In attaching and forming the angle adjuster 2 to the connection portion of the back plate 3 and the seat plate 3 'of the chair 1, it is integral with the seat plate support rod 7 "located at both edges of the seat plate 3'. Forming the gear box (7) to make a hole through the connecting rod (6 ") through the connecting rod (6") through the left and right plates in the center of the side of the gearbox (7), the opposite edge of the seat plate (3 ') The same gear box (7) and the connecting rod (6 ") installed in the connection to each other, and through the side end of the back support rod (4 ') and the gear box (7) to form a fixed groove (7') The inside of the gear box 7 is formed with a back support rod 4 'and a locking jaw 4 "installed to rotate the rotary gear 4 to adjust the angle, thereby fixing the leaf spring 8 to the fixing groove 7 ') And the locking jaw (4 ") to be elastic and the fixed gear (5) is always engaged with the rotary gear (4) by the coil spring (9), but the fixed gear (5) is formed on the lever (6)Will ensure that the hayeoseo detachable by the support projections (6 ').
이와같이 구성된 본 고안의 작용효과를 설명하며 다음과 같다.The following describes the effects of the present invention configured as described above.
좌판(3')의 양측 모서리에 위치된 좌판지지봉(7")이 기어박스(7) 내측 하단에 고정설치 되어 의자의 이용시 좌판(3')의 균형을 잡아주며, 좌판(3')의 양측 모서리 뒤쪽에 대향되게 설치된 기어박스(7) 측면의 중앙부분일측에 구멍을 내어 연결봉(6")으로 기어박스(7) 안쪽에 내장된 고정기어(5)에 관통 형성되어 상기 연결봉(6")일측에 설치된 레버(6)를 조절하여 등판(3)이 180°내에서 임의의 위치에 각도를 이룰수 있고 기어박스(7)내부에 형성된 회전기어(4)는 레버(6)에 의해 회전하여 각도를 조절할 때 등판지지봉(4')이 회전기어가 회전한만큼 각도를 변화시키어 이용자가 이용하기에 편하게 하도록 된 것으로, 제 4 도에 표시한 바와 같이 등판(3)이 고정되어 있는 상태에서 뒤로 제칠 경우 레버(6)를 밑으로 밀면 레버(6)의 단부에 형성된 지지돌기(6')가 고정기어(5)를 레버(6)의 선단쪽으로 밀어주게 되어 고정기어(5)와 회전기어(4)의 교합상태가 풀려 등판(3)을 임의의 각도로 위로 제칠 수 있고, 이때 고정홈(7')과 걸림턱(4")에 고정 설치된 판스프링(8)의 탄력에 의해 등판(3)이 필요없이 뒤로 제처지는 것을 방지하게 되고 들판(3)의 임의의 각도로 제처진 다음 이를 고정시키려면 밑으로 눌렀던 레버(6)를 위로 올리면 지지돌기(6')가 고정기어(5)에서 이탈되면서 코일스프링(9)이 고정기어(5)를 회전기어(4)쪽으로 밀어주게 되어 양 기어(5)(4)의 이가 맞물려져 등판(3)이 고정되는 것이다.The seat plate support rod 7 "located at both edges of the seat plate 3 'is fixed to the inner bottom of the gearbox 7 to balance the seat plate 3' when the chair is used, and both sides of the seat plate 3 '. A hole is formed at one side of the center portion of the side of the gearbox 7 opposite to the rear corner, and is formed through the fixed rod 5 built into the gearbox 7 with a connecting rod 6 ", thereby connecting the connecting rod 6". By adjusting the lever 6 installed on one side, the back plate 3 can be angled at any position within 180 °, and the rotary gear 4 formed inside the gearbox 7 is rotated by the lever 6 to be angled. When the back support bar 4 'is adjusted to change the angle as the rotary gear rotates to make it easier for the user to adjust, as shown in FIG. 4, when the back plate 3 is fixed in the fixed state, When the lever 6 is pushed downward, the support protrusion 6 'formed at the end of the lever 6 is fixed gear 5 ) Is pushed toward the tip of the lever 6 so that the mating state of the fixed gear 5 and the rotary gear 4 is released, and the back plate 3 can be squeezed up at an arbitrary angle, and the fixing groove 7 'and The elasticity of the leaf spring 8 secured to the catching jaw 4 "prevents the back plate 3 from being unnecessarily swept backwards, and is cut down at any angle of the field 3 and then downwards to fix it. When the lever 6 pushed up, the support protrusion 6 'is released from the fixed gear 5, and the coil spring 9 pushes the fixed gear 5 toward the rotary gear 4 so that both gears 5 The tooth of (4) is meshed and the back plate 3 is fixed.
이상과 같이 본 고안은 간단한 구조와 간편한 작동에 의해 본 고안의 목적하는바 등판을 희망하는 각도로 손쉽게 조절 사용할 수 있어 특히 노약자로로 사용하기에 간편한 것이다.As described above, the present invention can be easily adjusted and used at a desired angle of the back bar of the present invention by a simple structure and easy operation.
