Description
제1도는 본 고안의 단면도.1 is a cross-sectional view of the present invention.
제2도는 본 고안의 사용상태도이다.2 is a state diagram used in the present invention.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 고정관 1a : 합성수지제 안내관1: fixed tube 1a: synthetic resin guide tube
2 : 나사봉 3 : 용접부2: screw rod 3: welded portion
4 : 승강관 5 : 너트4: lifting pipe 5: nut
6 : 의자다리 7 : 좌대6: chair leg 7: base
8 : 제자리 회전대8: swivel in place
본 고안은 의자의 좌대 높이를 조절하는 조절장치에 관한 것으로 의자 다리의 중심부에 설치되는 고정관과 좌대의 제자리 회전대 사이에 승강관을 설치하여 수동으로 이를 승강 조정케 하므로서 의자 높이를 편리하게 조정할 수 있도록한 것이다.The present invention relates to a control device for adjusting the height of the seat of the chair to install the lifting pipe between the fixed tube installed in the center of the chair leg and the seat swivel in place so that the chair height can be conveniently adjusted It is.
종래에도 고정관과 의자 좌대 사이에 승강조절장치를 가설하여 의자의 높이를 조절케한 것이 다수종 개발되어 있으나 이를 고정관과 승강조정관 사이에 클러치를 장치하여 의자 좌대에서 사람이 내리고 의자 좌대를 회전시켜서 승강관을 회전시켜야 하므로 좁은 사무실에서 사용할때 조정작업이 매우 번거로운 결점이 있었다.Conventionally, many types have been developed in which a height adjustment device is installed between a fixed pipe and a chair seat to adjust the height of a chair. However, a clutch is installed between the fixed pipe and a lift adjuster so that a person falls from the chair seat and rotates the chair seat. Because the steel pipe had to be rotated, the adjustment was very cumbersome when used in a narrow office.
본 고안은 위와같은 종래의 결저을 시정하기 위하여 승강관 자체를 손으로 회전시켜 간단히 높이 조정이 가능케한 것인데 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is to enable a simple height adjustment by rotating the lifting tube itself by hand to correct the conventional bottom as described above in detail based on the accompanying drawings as follows.
의자다리(6)의 중심부에 설치되는 고정관(1)의 내부에 바닥에서 수직으로 나사봉(2)을 설치하고 입구측에 합성수지제 안내관(1a)을 삽입시키고 의자좌대(7) 저면에 장치된 제자리 회전대(8)에서 아래로 설치되는 승강관(4) 하단에 너트(5)를 부착하여 승강관이 합성수지제 안내관(1a)의 중심공을 통해 고정관 속의 나사봉(2)에 나사결합 되게한 구조이다.Install the screw rod (2) from the bottom vertically in the fixed tube (1) installed in the center of the chair leg (6), insert the synthetic resin guide tube (1a) on the inlet side and the device on the bottom of the chair seat (7) The nut (5) is attached to the lower part of the elevating pipe (4) installed downward from the in position rotating table (8) so that the elevating pipe is screwed into the screw rod (2) in the fixed pipe through the center hole of the synthetic guide pipe (1a). It is a structure.
이와같이 된 본 고안의 의자좌대의 제자리 회전대(8)에 상단이 접속된 승강관(4)이 의자다리(6) 중심부에 고정된 고정관(1)의 안내관(1a)으로 삽입되어 하단부의 너트(5)가 고정관속의 나사봉(2)에 나사결합되어 유지되므로 의자의 높이를 조정할 필요가 있을때 승강관(4)을 손으로 잡고 회전시켜서 좌대의 높이를 원하는 높이에 유지시킬수 있고 승강관(4)의 상단이 제자리 회전대(8)에 접속되어 있어서 좌대를 회전시키지 않고 의자좌대의 높이를 조절할 수 있는 이점이 있으며 반대로 의자에 앉아서 회전의자를 돌릴때는 승강관(4)의 회전되지 않게 되므로 일단 조정된 의자 높이가 사용중에 임의로 변경될 염려가 없는 이점이 있고 승강관체는 합성수지제 안내관(1a)에 상반부가 피복되고 하단의 너트(4)가 나사봉에 나착되므로 승강관의 요동도 방지되는 이점이 있어 실용적인 의자를 얻는 것이다.The elevating pipe 4 connected with the upper end to the seat 8 of the chair seat of the present invention thus formed is inserted into the guide tube 1a of the fixed pipe 1 fixed to the center of the chair leg 6 so that the nut of the lower end ( 5) is screwed to the screw rod (2) of the fixed tube, so when it is necessary to adjust the height of the chair can hold the elevating pipe (4) by hand to maintain the height of the seat to the desired height and the elevating pipe (4 ) Is the upper end of the seat is connected to the swivel table (8) has the advantage of adjusting the height of the chair seat without rotating the seat, on the contrary, when the chair is rotated, the lifting tube (4) is not rotated once adjusted There is an advantage that the chair height is not changed arbitrarily during use, and the elevating pipe body is coated on the upper half of the synthetic resin guide pipe (1a) and the nut (4) of the lower part is screwed on the screw rod, which prevents the fluctuation of the elevating pipe. This will have to get a practical chair.
