Description
제1도는 본고안의 종단면도.1 is a longitudinal cross-sectional view of the present article.
제2도는 종래것의 종단면도.2 is a longitudinal sectional view of the conventional one.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 지주관 2 : 나사봉1: holding pipe 2: screw rod
3 : 안내관 4 : 수직관3: guide tube 4: vertical tube
7 : 암나사선 8 : 방지판7: female thread 8: preventing plate
본 고안은 회전의자의 좌판 저면에 연결한 수직관을 다리 중앙에 수직으로 연결한 지관내에서 나사선에 따라 회전되며 승강되도록하여 좌판의 높이를 조절하는 회전의자의 좌판 높이 조절 장치에 관한 것이다.The present invention relates to a seat plate height adjusting device of a swivel chair that adjusts the height of the seat plate to be elevated and rotated according to the screw thread in the branch pipe connected vertically to the center of the leg vertically connected to the bottom plate of the swivel chair.
종래 높이 조절 장치로는 제2도에 나타난 바와같이 의자 다리 중앙에 입설시키는 지주관(101)내에 나사봉(102)을 수직으로 연결하고 상기 지주관(101)의 상단측 내경에 끼워지는 합성수지제의 안내관(103)을 삽착하고, 좌판 저면에 수직으로 연결시킨 수직관(104)의 하단에 너트(105)를 용접시켜 상기 안내관(103)의 내경으로 수직관(104)을 끼워 너트(105)를 나사봉(102)에 나사 결합시켜 너트(105)와 나사봉(102)의 나사선에 따라 수직관(104)이 회전되며 승강되도록 한 것이므로 나사봉(102)에 결합 되어 좌판의 회전과 승강 작동을 부여하게 되는 너트(105) 그 나사선이 너트(105)의 두께정도 밖에 안되어 나사봉(102)과의 결합 면적이 나사선으로 3-4개 정도의 피치 정도밖에 안되어 하중이 무거운 사람이 좌판에 앉을때 그 지탱하는 힘이 약하여 더욱이 좌판에 앉을때 얌전히 앉지 않을 경우에는 너트(105)의 나사선이 파손되어 결국 의자 전체를 못쓰게 되며, 또한 수직관(104)이 안내관(103)위로 빠지게 되는 이탈 방지 수단도 마련되어 있지 않으므로 너트(105)가 나사봉(102)을 이탈하게 되는 등의 결점이 있는 것이다.As a conventional height adjusting device, as shown in FIG. 2, a synthetic resin is inserted into the upper end side of the support pipe 101 by vertically connecting the screw rods 102 in the support pipe 101 to be placed in the center of the chair leg. Guide tube 103 is inserted, and the nut 105 is welded to the lower end of the vertical tube 104 vertically connected to the bottom surface of the seat plate, and the vertical tube 104 is inserted into the inner diameter of the guide tube 103. 105 is screwed to the threaded rod 102 so that the vertical pipe 104 is rotated and lifted in accordance with the threads of the nut 105 and the threaded rod 102 so that it is coupled to the threaded rod 102 to rotate the seat plate. The nut 105 to give the lifting operation is only about the thickness of the nut 105, the engagement area with the threaded rod 102 is only about 3-4 pitches with the screw thread, and the heavy load When sitting on the floor, the supporting force is weak, and when sitting on the seat, If not sitting, the screw thread of the nut 105 is broken and eventually the entire chair is not used, and since the vertical tube 104 is not provided with a separation preventing means for falling out of the guide tube 103, the nut 105 is a screw rod ( There is a flaw, such as a departure from 102).
따라서 본 고안은 상기와 같은 종래의 결점을 시정하여 의자를 반영구적으로 사용할 수 있도록 상기의 나사봉(102)가 결합되는 암나사선을 수직관(104)내경에 길게 형성시켜 나사선의 파손을 방지하도록 구성하여서된 것으로서, 이하 도면에 따라 상세히 설명하면 다음과 같다.Therefore, the present invention is configured to prevent the breakage of the screw thread by forming a female screw thread to which the screw rod 102 is coupled to the inner diameter of the vertical pipe 104 so that the chair can be used semi-permanently by correcting the above conventional defects. As will be described in detail below with reference to the drawings.
지주관(1)의 내경 하단에 나사봉(2)을 수직으로 연결하고, 지주관(1)의 상단 내경에 안내관(3)을 삽착하여 수직관(4)을 상기 나사봉(2)의 나사선에 따라 회전되며 승상되도록 상기 안내관(3)의 내경을 통하여 지주관(1)내부로 끼워 상기의 지주관(1)은 의자의 다리(5)중앙에 수직으로 연결하고 상기 수직관(4)은 좌판(6)의 저면에 연결시켜 좌판(6)의 회전수단과 높이 조절 수단을 겸하도록 한 것에 있어서, 상기의 수직관(4) 내경에 상기의 나사봉(2)이 끼워지는 암나사선(7)을 길게 형성하고, 수직관(4) 하단에 이탈 방지용 방지판(8)을 용접시켜 구성하여서된 것이다.The screw rod 2 is vertically connected to the lower end of the inner diameter of the support pipe 1, and the guide tube 3 is inserted into the upper inner diameter of the support pipe 1 so that the vertical pipe 4 is connected to the screw rod 2. The support pipe 1 is inserted into the support pipe 1 through the inner diameter of the guide tube 3 so that the support pipe 1 is vertically connected to the center of the leg 5 of the chair so as to be rotated according to the screw line and ascended. ) Is connected to the bottom of the seat plate 6 so as to serve as a rotation means and a height adjusting means of the seat plate 6, the female screw thread that the screw rod (2) is fitted to the inner diameter of the vertical pipe (4) (7) is elongated, and it is comprised by welding the preventive prevention plate 8 for separation | separation to the lower end of the vertical pipe 4, and is comprised.
이상과 같이된 본고안은 수직관(4)내경에 암나사선(7)을 길게 형성하였기때문에 종래 제2도에서 보는 것처럼 너트(105)의 암나선 보타는 나사봉(2)과의 결합면적이되는 피치의 수가 많아 그 지지력이 크므로 하중이 무거운 사람이 좌판(6)에 난폭하게 앉는다 하더라도 나사선이 파손되지 않게 되어 의자를 반영구적으로 사용하게되며, 또한 수직관(4) 하단에 방지판(8)이 부착되어 있어 방지판(8)이 안내관(3)에 걸리게 되므로 수직관(4)이 이탈되지 않는 작용효과를 나타내는 것이다.As described above, the female screw line 7 is formed long in the inner diameter of the vertical tube 4, so that the female screw thread of the nut 105 has a coupling area with the screw rod 2 as shown in FIG. Since the number of pitches is large and the supporting force is large, even if a person with a heavy load sits violently on the seat plate 6, the screw thread will not be broken and thus the chair will be used semi-permanently. ) Is attached to the prevention plate 8 is caught by the guide tube (3), so that the vertical tube (4) has an effect that does not escape.
