본 고안은 빈 의자로 좌대밑으로 설치된 승광관을 회전시키면 의자높이가 상하로 조정되고 사람이 좌대에 앉아서 좌대를 회전시키면 승광관이 회전하여도 높이 조정이 되지 않도록된 통상의 회전 의자의 높이 조절정치에 사용되는 접리장치의 개량에 관한 것이다.The present invention is to adjust the height of the conventional rotating chair so that the height of the chair is adjusted up and down when the chair is rotated up and down and the seat is seated on the seat and the height is not adjusted even if the elevator is rotated. It relates to the improvement of the folding device used for stationary.

즉 종래의 회전의자 승강장치는 승강작동관 하단에 접촉부가 있는 고정자를 장치하고 나사봉 외면에 너트를 나착하여 너트 하면으로 접촉홈을 만들어 승강작동관이 코일스프링에 의거 위로 탄발되게한 다음 코일스프링 하단과 너트사이에 드러스트 베어링을 장치하여 빈 의자로 승강작동관을 회전시키면 너트가 회전하여 의자높이가 조정되고 사람이 의자에 앉아서 승강작동관을 회전시키면 승광작동관의 하단이 너트와 이간되어 공회전되도록 하므로서 의자 높이가 조정되지 않도록 된 것이여서 구조가 복잡하고 승강조정장치에 속하는 너트와 접속홈 사이가 쉽게 마모되어서 수명이 오래가지 못하는 결점이 있었다.That is, the conventional rotary chair lifting device is equipped with a stator with a contact portion at the bottom of the elevating operation pipe, and a nut is attached to the outer surface of the screw rod to make a contact groove with the lower surface of the nut so that the elevating operation pipe is lifted up based on the coil spring, and then the lower of the coil spring. The thrust bearing is rotated to an empty chair by installing a thrust bearing between the nut and the nut. The nut rotates to adjust the height of the chair. When a person sits on the chair and rotates the elevating actuator, the lower part of the elevating actuator is separated from the nut and idle. As a result, the height of the chair is not adjusted so that the structure is complicated, and the nut and the connecting groove belonging to the elevating adjusting device are easily worn and have a long service life.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 안출한 것으로 이를 보다 상세히 설명하면 다음과 같다.The present invention has been devised to correct the above-described drawbacks, which will be described in more detail as follows.

의자 접지각(10)의 중심부에 고정되는 고정관(1)의 중심부에 나사봉(3)을 수직으로 설치하여 하단을 용접하고 고정관(1)의 개방부에 안내관(2)을 끼워 승강작동관(4)을 투입시켜 나사봉(3)에 나삽된 너트(7)와 승강작동관 사이에 코일스프링(6)을 장치하고 스프링 하단과 너트사이에 드러스트 베어링(8)을 장치하는 공지의 의자높이 조절장치에 있어서, 너트(7)의 하단부 둘레에 6각 축소부(7a)를 형성시키고 승강작동관의 하단의 6각 축소부(4a)를 형성시키며 승강작동관의 상측 단턱(4b)과 코일스프링(6)사이에 붓싱(5)을 내장하여서 코일스프링 조정길이를 짧게한 구조이다.Vertically install the screw rod (3) in the center of the fixed tube (1) fixed to the center of the chair ground angle (10) to weld the lower end and the guide tube (2) in the opening of the fixed tube (1) (4) A well-known chair in which a coil spring (6) is provided between the nut (7) screwed into the screw rod (3) and the elevating operating pipe, and a thrust bearing (8) is provided between the lower end of the spring and the nut. In the height adjusting device, a hexagonal reduction portion 7a is formed around the lower end of the nut 7, a hexagonal reduction portion 4a at the lower end of the elevating operation pipe is formed, and the upper stepped portion 4b of the elevating operation pipe is formed. The bushing 5 is embedded between the coil springs 6 to shorten the coil spring adjustment length.

이와같이된 본 고안은 빈 의자상태에서 승강작동관(4)을 회전시키면 스프링(6)의 탄력으로 너트(7)의 6각 축소부(7a)와 승강작동관의 하각6단 축소부(4a)가 서로 접속되어 하나로 되기 때문에 승강작동관(4)은 회전시키면 너트(7)가 회전하므로 높이가 조정되고 의자에 사람이 앉아 무게가 가해지면 코일 스프링(6)이 수축되면서 승강작동관(4)이 하강하여 6각 축소부(4a)가 너트(7)의 6각 축소부(7a)에서 이간 되기 때문에 승강작동관(4)을 회전하게되면 너트(7)가 돌지 않도록 되므로 높이 조정이 이루어지지 않아 사람이 의자에 앉아서 회전의자를 돌릴때는 높이 조정이 되지 않지만 빈 의자로 승강작동관을 돌리면 높이조정이 달성되는 효과를 얻을수 있고 승강작동관(4)의 상측 단턱(40)내부에는 붓싱(5)이 들어가서 그 길이만큼 코일스프링(6)의 길이를 짧게 할 수 있게 되는 이점이 있고 이로인해 작동관(4)에 요입홈을 만들지 않아도 되는 장점을 얻을수 있어서 부속이 적게들고 고장의 염려가 적은 실용적인 의자높이 조절장치를 얻게 되는 것이다.When the elevating operation tube 4 is rotated in the empty chair state, the present invention has the hexagonal reduction portion 7a of the nut 7 and the lower six-stage reduction portion 4a of the elevating operation tube. Are connected to each other, so that the elevating operating pipe (4) is rotated, the nut (7) is rotated, so that the height is adjusted, and when a person sits on the chair and the weight is applied, the coil spring (6) is contracted while the lifting operating pipe (4) Since the descending hexagonal reduction portion 4a is separated from the hexagonal reduction portion 7a of the nut 7, the height adjustment is not performed because the nut 7 does not rotate when the lifting operation pipe 4 is rotated. Therefore, when a person sits in a chair and turns the swivel chair, the height is not adjusted. However, when the elevator tube is turned to an empty chair, the height adjustment can be achieved, and the inside of the upper step 40 of the elevator tube 4 is bushing (5). ) To shorten the length of the coil spring 6 by that length. This is an advantage of being able and you'll have a working tube obtained in the benefits that (4) the need to create the required iphom less fear of failure holding less practical accessory seat height adjustment.
