Description

허리운동 기능을 갖는 사무용 의자{Office chair with waist exercise function}Office chair with waist exercise function

본 발명은 사무용 의자를 개량하여 사무를 보는 도중에 막간을 이용하여 좌대에 앉아 허리운동이 가능하도록 만든 사무용 의자에 관한 것인데 보다 구체적인 것은, 의자다리 중심부에 형성된 축대에 지지축을 착탈가능케 결합하여 회전축관을 설치하고 회전축관과 지지축 사이에 회전축관을 회전시키고 고정시키는 회전 제어장치를 형성하고 회전축관 외벽에 또 하나의 고정관체를 나란히 설치하여 회전의자용 승강축관을 접속시켜 사무용의자 좌대를 장치함에 따라 의자 좌대에 앉아 사무를 보는 도중에 시간을 할애하여 허리운동을 할 수 있게 하여 두가지 기능을 가지도록 구성한 것이다.The present invention relates to an office chair made to enable the waist movement while sitting on a pedestal while viewing office work by improving the office chair.More specifically, the support shaft is detachably coupled to the axle formed in the center of the chair leg to form a rotating shaft tube. After installing and forming a rotation control device that rotates and fixes the rotating shaft pipe between the rotating shaft pipe and the support shaft, another fixed pipe body is installed side by side on the outer wall of the rotating shaft pipe to connect the lifting shaft pipe for the rotating chair to install the office chair base. It is configured to have two functions by allowing you to do lower back exercises by spending time while sitting on the chair rest and doing office work.

종래에도 회전의자 받침대와 좌판을 연결하는 지지봉에 절곡부를 형성하고 좌판을 지지봉에서 회전이 자유롭게 구성하여 의자에 앉은 상태에서 발을 바닥에 접지하고 엉덩이를 돌려서 허리운동을 할 수 있게 만든 의자가 개발되어 있으나, 의자좌판이 언제나 회전될 수 있도록 되어 있어서 사무를 보는 중간에도 회동될 수 있기 사무용 의자로 적합지 못한 불편이 있었다.Conventionally, a chair was developed that formed a bent part on the support bar connecting the rotating chair base and the seat plate, and the seat plate was freely rotated on the support bar, so that while sitting on the chair, the feet were grounded on the floor and the hips were rotated to perform the waist movement. However, since the chair seat plate is designed to be able to rotate at any time, it is not suitable as an office chair because it can be rotated even during office work.

본 발명은 위와 같은 종래의 결점을 해소하기 위해 발명된 것이다.The present invention was invented to solve the above conventional drawbacks.

본 발명은 사무용 의자 다리 중심부에 형성된 축대에 지지축을 착탈가능케 결합하여 회전축관을 설치하고 회전축관과 지지축 사이에 회전제어장치를 하여 회전축관을 회전시키고 정지시킬 수 있게 한 회전제어장치와 회전축관 외면에 또 하나의 고정관체를 나란히 설치하여 회전의자용 승강축관을 접속시켜서 의자의 높낮이를 조정할 수 있게 한 장치를 통해 사무용 의자에서 허리운동을 할 수 있게 만든 것이다.The present invention is a rotation control device and a rotation shaft pipe that allows the rotation shaft tube to rotate and stop by installing a rotation shaft pipe by attaching a support shaft detachably to a shaft formed in the center of the office chair leg, and a rotation control device between the rotation shaft pipe and the support shaft. Another fixed tube body is installed side by side on the outer surface to connect the lifting shaft pipe for the rotating chair so that the height of the chair can be adjusted so that the back movement can be performed in the office chair.

이와 같이 된 본 발명은 사무용 의자다리(1) 중심부에 형성된 축대(1a)에 지지축(2) 하단부(2a)를 결합하고 지지축(2) 외면에 베어링(B)(B')을 끼우고 회전축관(3)을 끼워 제자리 회전되게 하고 회전제어장치를 구비한 다음 회전축관(3) 외면에 회전축관과 나란하게 부착시킨 고정관체(4)를 형성하여 회전 의자용 승강축관(5)를 결합시켰기 때문에 의자다리 지지축과 좌대의 승강축관이 일정간격으로 어긋나게 두개의 축을 가지는 의자가 구성되고 회전축관 주벽에 안내관(3a)이 형성되어 수용실(3b)에서 주벽으로 구멍(3c)이 형성되고 구멍입구에 구멍 직경보다 확장되는 안내홈(3d)이 구멍 직경을 관통하는 방향으로만 형성되어 수용실(3b)에 장치된 작동간(11)의 안내돌편(11b)이 안내홈(3d)에 삽입되거나 안내홈 입구에 걸쳐지도록 조정하는 방법에 의하여 선단돌출부(11a)가 구멍(3c)을 통해 지지축의 고정홈(2b)에 삽입되거나 이간되는 조정이 가능케 되므로 회전축관(3)이 지지축(2)에서 회전되거나 고정되도록 회전동작을 제어할 수 있는 회전 제어가 가능하게 되고 작동간(11)의 선단 안내돌편이 안내홈에 삽입된 상태에서는 코일스프링(10)의 압력을 받으므로 스스로 탈출할 수 없게 된다.In the present invention as described above, the support shaft (2) lower end (2a) is coupled to the shaft (1a) formed in the center of the office chair leg (1), and the bearing (B) (B') is inserted on the outer surface of the support shaft (2). The rotating shaft pipe (3) is inserted to rotate in place, and a rotation control device is provided, and then a fixed pipe (4) attached in parallel with the rotating shaft pipe (4) is formed on the outer surface of the rotating shaft pipe (3) to combine the lifting shaft pipe (5) for a rotating chair. Because of this, a chair having two axes is formed so that the support shaft of the chair leg and the lifting shaft pipe of the base are shifted at regular intervals, and a guide pipe (3a) is formed on the main wall of the rotary shaft pipe, and a hole (3c) is formed from the accommodation chamber (3b) to the main wall. The guide groove (3d) is formed only in the direction penetrating the hole diameter at the hole entrance, so that the guide stone piece (11b) of the operating section (11) installed in the accommodation chamber (3b) is the guide groove (3d) The rotation shaft pipe (3) can be adjusted to be inserted into or separated from the fixing groove (2b) of the support shaft through the hole (3c) through the method of adjusting to be inserted into the guide groove inlet. (2) Rotation control that can control the rotation operation so that it is rotated or fixed is possible, and in the state where the tip guide stone piece of the operation section 11 is inserted into the guide groove, it is self-escaping because it receives the pressure of the coil spring 10. It becomes impossible to do.

따라서 회전축관이 지지축관에서 고정된 상태에서는 의자좌대(6)를 회전시킬 수 없게 되므로 사무용 의자로 사용할 수 있고, 좌대에 앉아서 허리를 회전시키는 허리운동을 하고자 할 때는 지지축(2)과 회전축관(3)을 연결하는 회전제어장치를 해제시키고 좌대의 높이를 조정하여 두발을 지면에 붙이고 회전축관이 지지축에서 회전하게 되면 좌대가 지지축을 중심으로 회전하므로 좌대에 앉아서 허리를 회전시킬 수 있게 되어 허리운동기로 사용할 수 있게 되는바 두가지 용도로 구분하여 사용할 수 있는 이점이 있다.Therefore, when the rotation shaft tube is fixed in the support shaft tube, the chair rest 6 cannot be rotated, so it can be used as an office chair. When you want to perform a waist motion to rotate the waist while sitting on the base, the support shaft 2 and the rotation shaft tube (3) Release the rotation control device that connects the base, adjust the height of the base, attach your feet to the ground, and when the rotation shaft tube rotates on the support shaft, the base rotates around the support axis, so you can sit on the base and rotate your waist. Since it can be used as a waist exercise machine, it has the advantage of being able to use it for two purposes.

또, 회전의자 좌대 높이가 맞지 않으면 승강작동레버(7)를 작동시켜서 승강축관(5) 작동돌기(5c)를 작동시켜 좌대높이를 높이거나 낮출 수 있으므로 체격에 알맞은 좌대높이를 유지할 수 있다.In addition, if the height of the seat of the rotating chair does not match, the height of the seat can be increased or lowered by operating the lifting shaft pipe 5 and the operating protrusion 5c by operating the lifting operation lever 7, so that the height of the seat suitable for the physique can be maintained.

그러므로 본 발명은 사무용 의자를 사용하는 도중에 회전제어장치의 작동간(11)을 조작하여 허리운동용이 가능한 의자로 변환시켜 허리운동을 하고 다시 복원시켜서 사무용 회전의자로 전환시킬 수 있기 때문에 두가지 용도에 편리하게 사용할 수 있는 이점을 얻게 된다.Therefore, the present invention is convenient for two uses because it can be converted into a chair capable of waist movement by manipulating the operating interval 11 of the rotation control device while using the office chair, and converting it to a rotating office chair by restoring it. You will get the advantage that you can use it.

또, 본 발명은 고정관체(4)를 부착한 회전축관(3)을 부품으로 만들어 의자에 조립할 수 있으므로 일반의자에 본발명을 적용시켜 허리운동이 가능한 사무용 회전의자로 만들수 도 있어 활용이 편리한 이점이 있다.In addition, the present invention can be assembled into a chair by making the rotating shaft tube 3 attached to the fixed tube 4 as a part, so it is possible to apply the present invention to a general chair and make it an office rotating chair capable of lower back movement. There is this.
