Description
본 고안은 의자의 등판높이 조절장치에 관한 것으로, 더욱 구체적으로는 좌대에 고정된 등판받침대에 등판고정대를 상하로 승강시켜 등판높이를 조절할때 단계별로 조절하고자 하는 정지위치확인이 용이하고 등판조절과정에서 등판의 무게중심에 의해서 등판이 자연적으로 하강하는 것을 방지할수 있도록한 것이다.The present invention relates to a chair height adjustment device of the chair, and more specifically, it is easy to check the stop position to be adjusted step by step when adjusting the height of the back by lifting the back plate up and down on the backrest fixed to the seat. By the center of gravity of the back to prevent the back to fall naturally.
종래에도 등판받침대에 등판고정대를 결합하여 등판높이를 상하로 조절하되 등판받침대에 설치된 탄성걸림간이 등판고정대의 안내홈에 끼워져서 상기 탄성걸림간이 안내홈의 외측수직공간부에 있을때는 등판을 최상단 위치에서 최하단 위치까지 끌어내릴수 있게 안내시킨 다음 내측접속공간부에 내입된 상태에서 등판을 소정높이까지 들어올려 접속공간부의 다단걸림턱에 탄성걸림간의 걸림핀이 선택적으로 결합되면 등판이 하강위치로 내려가지 않도록한 고정수단으로 되어 있었다.Conventionally, the height of the back plate is adjusted up and down by combining the back plate holder with the back plate but the elastic locking bar installed in the back plate is inserted into the guide groove of the back plate, so that the top of the back plate is in the outer vertical space of the guide groove. The guide is pulled down to the lowest position at, and then the back plate is lifted to a predetermined height in the state of being in the inner connection space, and when the locking pins between the elastic catches are selectively coupled to the multi-stage locking jaws of the connection space, the back plate is lowered to the lowered position. It had a fixed means.
그러나 상기에서는 등판높이를 조절하는 정지위치 확인이 쉽지 않았으므로 정지위치를 맞추기 위해 여러번 등판을 최상단 높이로 들어올린다음 다시 최하단으로 하강시켜야 하는 번거로움이 있고 단계별 걸림턱에 탄성걸림간이 결합되면 등판이 하강위치로는 내려가지 않지만 위로는 쉽게 들어올려지므로 조절된 등판높이가 쉽게변동될 염려가 있을뿐만 아니라 등판이 최상단 위치에 놓였을때 등판의 무게중심에 의해 자연적으로 급격한 하강이 이루어지므로 안전사고의 발생염려도 있었다.However, in the above, it was not easy to check the stop position to adjust the height of the back plate, so it was troublesome to lift the back plate to the highest level several times to adjust the stop position and then lower it back to the bottom end. Although it does not go down to the lowered position, it is easily lifted up, so there is a possibility that the height of the adjusted back plate is easily changed, and when the back plate is placed at the top position, the descending naturally occurs sharply due to the center of gravity of the back plate. There was also concern.
본 고안은 이러한 문제점을 해결하기 위하여 등판받침대에 등판고정대를 결합하여 등판높이를 상하로 조절하되 등판받침대에 볼접속홈을 다단으로 형성하고 등판고정대 하부중앙의 돌출편 결합공에 스프링으로 탄성지지되게 볼을 끼워 상기 볼접속홈에 선택적으로 대응접속되게한 것이다.In order to solve this problem, the present invention is to adjust the height of the back plate up and down by combining the back support to the backrest, but the ball connection groove is formed in multiple stages on the backrest, and elastically supported by the springs in the protrusions of the lower part of the backrest. By inserting a ball to be selectively connected to the ball connection groove.

수직의 등판받침대(10) 일측벽에 걸림핀(12a)을 가진 탄성걸림간(12)이 설치되고 하단은 수평으로 절곡된 결착부(11)가 형성되어 좌대에 고정할수 있게되며 상기 등판받침대(10)에 등판고정대(20)를 결착판(20a)으로 결합하되 등판받침대(10)의 탄성걸림간(12)이 등판고정대(20)의 안내홈(21)에 끼워져서 등판고정대(20)를 상하로 승강시켜 등판높이를 조절하게 된다.An elastic hook 12 having a locking pin 12a is installed at one side of the vertical backrest 10 and a bottom 11 is formed with a fastening portion 11 that is bent horizontally so that the backrest can be fixed to the seat. 10) The backing fixture 20 is coupled to the binding plate 20a, but the elastic latching section 12 of the backing base 10 is fitted into the guide groove 21 of the backing bracket 20 so that the backing fixture 20 is mounted. The height of the board is adjusted by lifting up and down.
상기 안내홈(21)은 외측에 수직공간부(22)가 형성되고 내측은 접속공간부(23)에 경사각도의 걸림턱(23a)이 다단으로 형성되며 안내홈(21) 상측은 내향경사면(24)이 형성되어 탄성걸림간(12)을 접속공간부(23)로 내입시키고 하측은 외향경사면(25)이 형성되어 탄성걸림간(12)를 수직공간부(22)로 유도하게 된다.The guide groove 21 has a vertical space portion 22 is formed on the outside, the inner side is formed in the connecting space 23, the locking step 23a of the inclination angle in multiple stages, the upper side of the guide groove 21 is an inward inclined surface ( 24 is formed to incorporate the elastic interlocking space 12 into the connection space 23, the lower side is formed with an outward inclined surface 25 to guide the elastic interlocking space 12 to the vertical space 22.
이러한 구성에서 본 고안은 상기 등판받침대(10)의 탄성걸림간(12) 하부에 볼접속홈(13)을 다단으로 형성하고 등판고정대(20) 하부 중앙의 돌출편(26)에 형성된 결합홈(27)에 스프링(28a)으로 탄성지지되게 볼(28)을 끼워 상기 볼접속홈(13)에 선택적으로 대응접속되게한 것이다.The present invention in such a configuration is formed in the lower end of the resilient latch 12 of the backrest 10, the ball connecting groove 13 in multiple stages and the engaging groove formed in the protrusion 26 of the lower center of the back plate fixing 20 ( The ball 28 is inserted into the spring 28a so that the ball 28 is elastically supported to the ball connecting groove 13.
이때, 상기 탄성걸림간(12)이 안내홈(21)의 내측접속공간부(23)에 형성된 다단걸림턱(23a)에 결합되는 시점과 볼접속홈(13)에 볼(28)이 접속되는 시점은 동일하게 이루어지도록 한다.At this time, the ball 28 is connected to the ball connecting groove 13 and the point of time when the elastic engaging space 12 is coupled to the multi-stage locking jaw (23a) formed in the inner connection space 23 of the guide groove 21. The point of view is the same.
도면중 미설명부호 29는 등판고정대 안내벽, 29'는 밀착지지편, 30은 고정볼트이다.In the drawings, reference numeral 29 denotes a guide wall for climbing the stator, 29 'is a close supporting piece, and 30 is a fixing bolt.
이와같이된 본 고안은 등판받침대(10)의 결착부(11)를 좌대에 고정시키고 등판받침대(10)에 결합되어 상하로 승강작동되게한 등판고정대(20)에 등판을 고정시켜 등판높이를 상하로 조절하게 된다.The present invention thus secures the binding portion 11 of the backrest 10 to the seat and is coupled to the backrest 10 to secure the backrest to the backrest 20 to be moved up and down the backrest height up and down Will be adjusted.
즉, 도 2에서와 같이 등판받침대(10)의 탄성걸림간(12)이 등판고정대(20)의 안내홈(21) 내측에 있는 접속공간부(23)에 위치하여 탄성걸림간(12)의 걸림핀(12a)이 접속공간부(23)의 다단걸림턱(23a)에 결합되면 등판이 하강되지 않고 고정된 상태를 유지하게 된다.That is, as shown in FIG. 2, the elastic engaging section 12 of the backrest base 10 is located in the connection space 23 inside the guide groove 21 of the backrest fixing plate 20, When the engaging pin 12a is coupled to the multi-stage catching jaw 23a of the connection space 23, the back plate is not lowered and remains fixed.
그리고 도 4에서와 같이 등판높이를 높이기 위해 위로들어 올리면 걸림핀(12a)이 경사각도의 걸림턱(23a)을 미끄러지듯이 빠져서 그 하부쪽의 걸림턱(23a)에 결합이 가능하게 되고 계속해서 등판을 최상단 높이로 들어올리면 도 4에서와 같이 탄성걸림간(12)이 내측의 접속공간부(23)를 벗어나서 외향경사면(25)에 위치하게 되므로 이러한 상태에서 등판을 밑으로 내리게 되면 탄성걸림간(12)이 외측수직공간부(22)에 놓여지게 되며 등판이 최하단 위치에 놓일때는 탄성걸림간(12)이 안내홈(21)의 내향경사면(24)에 위치하여 접속공간부(23)로 안내하므로 등판을 들어올리는 방법으로 높이를 조절하게 되는 것이다.And when lifted up to increase the height of the back plate, as shown in Figure 4, the locking pin 12a slips off the locking jaw (23a) of the inclination angle, it is possible to be coupled to the locking jaw (23a) of the lower side and continues the back When lifted to the uppermost height, as shown in Figure 4, the elastic engaging interval 12 is located on the outward inclined surface 25 outside the inner connection space 23, so in such a state to lower the back plate in this state, the elastic engaging interval ( 12) is placed in the outer vertical space portion 22, and when the back plate is placed at the lowermost position, the elastic catching portion 12 is located on the inward inclined surface 24 of the guide groove 21 to guide to the connection space portion 23. So you will adjust the height by lifting the back.
이때 본 고안에서는 상기 탄성걸림간(12)의 걸림핀(12a)이 접속공간부(23)의 걸림턱(23a)에 결합되는 시점과 등판받침대(10)의 볼접속홈(13)에 등판고정대(20)의 볼(28)이 접속되는 시점이 일치하므로 다단의 볼접속홈(13)을 보고 쉽게 단계별로 조절하고자 하는 정지위치 확인이 용이하고 그리고 등판을 최상단위치에서 최하단으로 내려보낼때에도 볼(28)에 의해서 등판이 급격하게 하강되는 것을 방지하게 된다.At this time, in the present invention, the locking pin 12a of the elastic latching portion 12 is coupled to the locking projection 23a of the connection space 23 and the backrest fixing rod 13 in the ball connecting groove 13 of the backrest 10. As the ball 28 of the 20 is connected to the same point of view, it is easy to check the stop position to easily adjust step by step by seeing the multi-stage ball connection groove 13 and even when the back plate is lowered from the top position to the bottom end ( 28) it is possible to prevent the back plate from falling sharply.
또한, 등판높이를 조절한 상태에서 등판이 쉽게 들어올려지지 않으므로 등판높이가 쉽게 변동되는 것을 방지하게 된다.In addition, since the back plate is not easily lifted in the state in which the back plate height is adjusted, the height of the back plate is prevented from being easily changed.
이와같이 본 고안은 등판높이를 조절할때 단계별로 조절하고자 하는 정지위치확인이 용이하므로 간편하고 정확하게 할수있고 등판조절과정에서 등판이 무게중심에 의해 급격하게 하강하는 것을 막고 등판조절상태가 쉽게 변동될 염려가 없는 이점이 있는 것이다.As such, the present design makes it easy to check the stop position to be adjusted step by step when adjusting the height of the back plate, so it can be done easily and accurately. There is an advantage.
