본 고안은 회전의자의 다리 중심에 설치하여 사용하는 회전의자의 높이조정장치에 관한 것으로서 회전의자의 높이를 보다 간단하고 쉽게 조정할 수 있게하고, 조정된 의자높이를 변동없이 조정해놓은 상태를 유지할 수 있게 한 것이다.The present invention relates to a height adjusting device of a swivel chair installed and used in the center of the leg of the swivel chair, so that the height of the swivel chair can be adjusted more simply and easily, and to maintain the adjusted chair height without change. It is.
종래의 회전의자는 바퀴가 부착된 다리 상부 중심에 지지관체를 고정하여 이곳에 좌판 저면에 고정된 승강지주봉을 삽설하여 승강지주봉에 형성된 홈에 고정보울트를 고정토록 구성되어 있어 의자의 높이를 조정할려면 좌판 지주봉에 체결된 고정보울트를 풀고 의자높이를 조정한 후 다시 고정보울트로 승강지주봉을 고정되게하여 의자의 높이를 조정되게 하였으나 이는 의자의 높이 조정작업을 하기가 불편할 뿐 아니라 조정된 높이는 의자 사용중에 좌판을 고정시켜 놓은 보울트의 끝부분이 망가지면서 좌판이 아래로 내려앉는 경우가 빈번하게 발생되어 다시 높이를 조정해야 되는 결점이 있었다.Conventional swivel chair is fixed to the support body in the upper center of the leg attached to the wheel to insert a lifting rod fixed on the bottom of the seat plate here is configured to fix a high information bolt in the groove formed on the lifting base rod to increase the height of the chair To adjust the height of the chair, loosen the high information bolt fastened to the seat holding rod and adjust the height of the chair, and then adjust the height of the chair by fixing the lifting base pole with the high information bolt, which makes it difficult to adjust the height of the chair. The height of the seat was fixed frequently while the end of the bolt that fixed the seat plate was broken while the chair was in use.
본 고안은 위와같은 종래의 결점을 해결하기 위해 작동레버를 위로 잡아당기면 좌판이 고정된 좌판 지주관을 회동축에 잡아주든 철구가 밖으로 튀어나오게 하여 좌판 지주관과 회동축의 잠금을 해지시켜 좌판 지주관을 상, 하로 승강 조정할 수 있게 하고 조정이 끝난후 작동레버를 아래로 내리면 철구가 좌판 지주관과 회동축공을 잡아줄 수 있게 구성하여 회전의자의 높이 조정작업을 간단하고 쉽게 할 수 있게 한 것으로써 첨부도면에 의거 보다 구체적으로 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention pulls up the operating lever, and the steel plate protrudes out of the seat plate holding the seat plate fixed to the pivot shaft, and then releases the lock on the seat pillar and the pivot shaft. The main body can be adjusted up and down, and when the adjustment lever is lowered after the adjustment is completed, the steel ball can hold the seat plate and the pivot shaft to make the adjustment of the height of the swivel chair simple and easy. According to the accompanying drawings in more detail as follows.
회전의자의 다리 중심에 삽설 고정되는 지지관체(1)의 내면부 중심의 받침부(15)에 상면부로 일정간격의 환홈(3a)이 형성된 회동축(3)을 수직으로 고정시키고 회동축 상부에는 두개의 철구안내공(6a)(6b)이 양측으로 형성된 승강관(6)을 삽설하여 상단부에 이탈 빙지륜(19)을 끼워 지지시키고 철구 안내공(6a)(6b)과 환홈(3a) 사이에 철구(7)를 접어 넣고 승강관 둘레에 좌판 지주관(2)의 하단에 받침구(9)를 삽입하며 받침구 내측에 주름관(4)을 삽입하여 누름관 하단에 고정된 개폐구(5)를 코일 스프링(8)에 장진되게 하고 개폐구(5)의 내측주벽에 철구직경의 절반보다 낮은 대피홈(5a)을 형성시키며 누름관 상단부에 레버(16)의 작동부와 접촉되게 한 구조이다.The pivot shaft 3, which has an annular groove 3a at regular intervals, is vertically fixed to the base 15 of the inner surface portion of the support tube 1 that is inserted and fixed to the center of the leg of the swivel chair. Inserting the elevating pipe (6) formed with two steel ball guide holes (6a) (6b) on both sides to support the release ice ring (19) at the upper end and between the steel ball guide holes (6a) (6b) and the ring groove (3a) Opening and closing the iron ball (7) in the lower end of the seat plate holding pipe (2) around the elevating pipe (9) and inserting the corrugated pipe (4) inside the support hole fixed to the bottom of the pressing pipe (5) To the coil spring (8) and to form the evacuation groove (5a) of less than half of the steel ball diameter on the inner circumferential wall of the opening and closing hole (5) and to contact the operating part of the lever 16 in the upper end of the press tube.
이와같이 구성된 본 고안은 손잡이(17)를 잡고 작동레버(16)를 위로 잡아 당기면 작동레버의 내측 작동부가 누름관(4)을 아래로 눌러 이누름관의 가압에 의해 누름관이 하향하면서 동시에 개폐구(5)과 승강관(6) 외면에서 약간 하강하기 때문에 대피홈(5a)으로 회동축(3)의 환홈(3a)과 승강관(6)의 철구 안내공(6a)(6b) 사이에 들어있는 철구(7)가 개폐구의 하강 압력으로 외향하여 대피홈(5a) 쪽으로 이동하기 때문에 지주관(2)과 회동축(3) 사이에 결착이 해재되고 좌판 지주관(2)을 아래로 이동시킬 수 있도록 되기 때문에 좌판 높이를 조정할 수 있어 좌판을 조정하고저 하는 높이에 적당하게 맞춘후 손으로 잡고 있든 작동레버(16)를 놓으면 코일스프링(8)의 탄력에 의해 개폐구가 위로 상승되어 철구(7)를 출입공(6a)으로 강제로 밀어넣은 후 출입공을 봉쇄시켜 주고 철구(7)가 회동축(3)의 환홈(3a)과 지주관의 승강관(6) 안내공(6a)(6b)에 철구가 협지되어 좌판 지주관이 회동축(3)에 고정되므로 회전의자의 높이조정 작업을 간단하고 쉽게 할 수 있는 이점을 얻을 수가 있고 좌판 지주관(2)과 회동축(3)의 고정상태가 견고해 의자 사용중에 좌판이 밑으로 내려앉을 우려가 없으며 승강 지주관(2)을 코일스프링(11)으로 밑에서 받쳐주는 형태로 구성되어 있어 의자 높이 조정작업을 보다 부드러운 상태에서 할 수 있게 한 것이다.The present invention configured as described above, by holding the handle 17 and pulling up the operating lever 16, the inner operating part of the operating lever presses down on the presser tube 4, and the presser tube is downward by pressurizing the presser tube. 5) and the lower part of the elevating pipe (6), so that the evacuation groove (5a) is located between the annular groove (3a) of the rotating shaft (3) and the steel ball guide hole (6a) (6b) of the elevating pipe (6) Since the iron ball 7 moves outwardly toward the evacuation groove 5a by the downward pressure of the opening and closing port, the binding between the support pipe 2 and the pivot shaft 3 is released and the seat plate support pipe 2 can be moved downward. The height of the seat can be adjusted so that the seat can be adjusted accordingly and adjusted to the height to be lowered, and then the lever (16) can be released by the elasticity of the coil spring (8). To force the entry into the entry hole (6a) and block the entry hole The steel ball 7 is rotated because the steel ball is clamped in the annular groove 3a of the pivot shaft 3 and the elevating pipe 6 of the support pipe 6 and the guide hole 6a, 6b so that the seat plate support pipe is fixed to the pivot shaft 3. The advantage of simple and easy adjustment of the height of the chair can be obtained, and the seat plate holding pipe (2) and the rotating shaft (3) are firmly fixed so that the seat plate can not be lowered while the chair is in use. (2) is configured to support the coil spring (11) from the bottom to enable the chair height adjustment work in a more smooth state.
