본 고안은 괘지구의 괘탈장치가 있는 책상판 지주봉 속으로 괘지요홈이 일정한 간격으로 환설되어 있는 좌대의 고정봉을 삽설하여 책상판이 상하 이동함에 따라 지주봉의 괘지구가 좌대의 고정봉의 괘지요홈에서 차례로 괘탈자재되게 하여 책상판의 높이를 혼자힘으로도 신속하고 간편하게 조절할수 있게한 책상판의 높이 조절장치에 관한것이다.The present invention inserts the fixed rod of the seat where the recess is recessed at regular intervals into the desk plate holding rod of the ruler, and as the desk plate moves up and down, the ruler of the support rod moves from the anchorage of the fixed rod to the seat. It is related with the height adjustment device of the desk plate which in turn can be quickly and easily adjusted even by a single power by allowing it to be demagnetized.

종래에도 그와같은 책상판을 상하 이동자재시켜 그 높이를 조절할수 있게한 책상다리가 여러가지로 연구 고안된바 있고 특히 본 출원인이 연구개발하여 출원(83-3867)호 중에 있는 책상다리 높이 조절장치도 좌대에 지지각과 책상판의 지주봉으로 분리되어 책상판의 지주봉 속에 좌대의 지지각이 삽설된 채 지주봉에 있는 괘탈장치의 괘지볼이 지지각의 괘지공에 순차적으로 괘탈자재되어지면서 책상판의 높이가 조정되어지도록 하였으나 이와 같은 구성으로 결합되어지는 책상다리는 책상판의 높이를 상하 조절할시에 책상판의 지주봉을 따라 상하이동하는 괘지볼이 이 동중에 다단으로 천공되어 있는 지지각의 괘지공 속에 항시 삽탈 되어지도록 괘지볼과 괘지공을 일치시키는 가공 및 조립이 용이하지 못하여 이의 생산능률이 저조하였고 조립후에도 불량품의 발생이 다대하여 제조단가를 높이는 결함이 있었다.In the past, the desk legs that can adjust the height by moving such a desk plate up and down has been researched and devised in various ways. In particular, the desk leg height adjusting device, which has been researched and developed by the applicant (83-3867), is also provided on the seat. The height of the desk board is adjusted by separating the support angle and the support bar of the desk plate, and the support ball of the jacking device of the support bar is inserted into the support hole of the support angle sequentially while the support angle of the seat is inserted in the support bar of the desk plate. However, the desk legs that are combined in such a configuration will always be inserted into the hanging balls of the support angles, which are drilled in multiple stages along the holding rods of the desk plates when the height of the desk plate is adjusted up and down. It is not easy to process and assemble the ball to match the ball, so its production efficiency is low. For all defective in the defect was caused to increase the manufacturing cost.

본 고안은 상기한 바와같은 결점을 시정하기 위하여 하단에 좌대가 있고 내부가 중공부로된 지지각의 내부 중앙에 높이 조절용 괘지요홈이 일정한 간격으로 다단으로 요설된 고정봉을 입설하고 책상판이 있는 지주봉에는 작동관의 압압작동에 따라 벌어지고 오무라지는 괘지구를 스프링으로 탄착 고정시켜 이의 괘지구가 좌대의고정봉에 관삽된 상태에서 괘지요홈에 차례로 괘탈되어지게 하므로서 지주봉으로 하여금 고정봉의 괘지홈 위치에 따라 책상판의 높이를 임의로 조정할수 있게한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.In order to correct the defects described above, the present invention has a pedestal at the bottom and a fixed rod in which the height adjustment ruler grooves are arranged in multiple stages at regular intervals in the inner center of the support angle of the hollow portion, and the props are provided with a desk plate. The rod is opened according to the pressing operation of the operating tube, and the crater is fixed with a spring, so that the hanging rod is inserted into the hanging groove in turn while being inserted into the fixed rod of the seat. The height of the desk plate can be arbitrarily adjusted according to the position of the hanging groove, which will be described in detail based on the accompanying drawings.

The insertion bar was evacuated and its hanging part (9) collapsed. The through-hole (8) of the hanging fitting (11) was fixedly arranged at regular intervals to arrange the hanging groove (14) around the outer wall. 15) is inserted into the bottom of the structure is fixed to the bottom of the support angle (4) vertically.

도면중 미설명부호 17은 작동키이다.In the drawing, reference numeral 17 denotes an operation key.

이와같이된 본 고안은 좌대(22)의 지지각(4)중앙에 입설된 고정봉(15)이 내관 (3)의 지착공(13)에 수직으로 고정되어 있는 괘착구(11)의 관통공(8)속으로 삽입 통과되고 작동봉(15)은 스프링(12)에 탄동되어 이의 대피홈(6)에 괘착구(11)의 돌연부 (7)가 대피되어 내측으로 오무리고 있어서 괘착구(11)의 괘지돌연부(9)로 하여금 고정봉(15)의 괘지요홈(14)에 꽉물리어진채 괘지되어지게 하므로서 도면 제3도의(a)에 도시한 바와같이 괘착구(11) 및 지주봉(2)과 일체로 되어 있는 책상판(1)은 고정봉 (15)과 지지각(4)와 일체로 되어 있는 좌대(22)에서 상하 좌우로요 동됨이 없이 설정시켜 놓은 지지각(4)높이에서 완강하게 지지되어지게 된다.The present invention as described above is a through-hole (11) of the fastener (11) is fixed to the anchoring hole (13) of the inner tube (3) is installed in the center of the support angle (4) of the seat (22) ( 8) inserted into the operation rod 15 is pushed into the spring (12) and the evacuation portion (7) of the fastener 11 is evacuated to the evacuation groove (6) thereof and squeezed inward so that the fastener (11) As shown in (a) of FIG. 3, the hanging fasteners 11 and the struts are caused by the hanging protrusions 9 of Fig. 3 being gripped by the hanging grooves 14 of the fixing rod 15. The desk plate (1), which is integrated with the rod (2), has the height of the support angle (4) that is set up and down without swinging up and down from the base (22) integral with the fixed rod (15) and the support angle (4). Will be firmly supported by.

따라서 책상판(1)의 높이를 상하로 이동 조정코자 할때에는 작동키(17)를 위로올려 지렛대의 요령으로 작동관(5)의 상부를 눌러 내리면은 작동관(5)하단의 스프링 (12)은 평연부(3')에 의하여 지주봉(2)에 고정되어 있는 내관(3)의 저면에서 눌러내리어지는 작동관(5)에 압축되고 내관(3)저면의 치착공(13)에 입설되어 있는 괘착구 (11)의 돌연부(7)는 방사상의 절결부(10)에 의하여 탄성이 부여되어 있어서 하향 이동하는 작동관(5)의 (대피실(6)에서 빠지는 순간에 자체의 탄성복귀력에 의하여 외향으로 벌어지면서 관통공(8)상부의 괘지돌연부(9)로 하여금 도면 제3도의(b)에 도시한 바와같이 고정봉(15)의 괘지요홈(14)에서 발탈되어 이의 괘지요홈(14)을 해지하게 된다.Therefore, when you want to move the height of the desk plate (1) up and down, push the operation key (17) up and push down the upper part of the operating tube (5) by the trick of the lever spring (12) at the bottom of the operating tube (5) Compressed to the working tube (5) pressed down from the bottom of the inner tube (3) fixed to the holding rod (2) by the plain edge (3 ') and installed in the dent hole (13) of the bottom of the inner tube (3) The elastic part 7 of the fastening part 11 has elasticity by the radial cutout part 10, and has its elastic return force at the moment of falling out of the evacuation chamber 6 of the operation pipe 5 which moves downward. As shown in (b) of FIG. 3, the rubbing portion 9 of the upper part of the through hole 8 is displaced out of the hanging groove 14 of the fixing rod 15 while being opened outward. The recess groove 14 is terminated.

그러나 이때의 괘착구(11)의 괘지돌연부(9)는 고정봉(15)의 괘지요홈(14)에서 해지되기는 하였으나 괘지정도가 극히 미미하게 되도록 하여 책상판(1)이 자중에 의하여 저절로 하강되어지지 않도록하되 책상판(1)에 약간의 외력만 가하며 상하 이동할수 있도록 하였으므로 이때에는 혼자힘으로도 책상판(1)을 들어 올린다든지 눌러내리더라도 괘착구(11)의 괘지돌연부(9)가 고정봉(15)의 괘지요홈(14)에서 용이하게 탈리되어 지므로 그 높이를 자유자재로 조절할수 있는 것이다.However, at this time, the rubbing portion 9 of the hanging fitting 11 is released from the hanging groove 14 of the fixing rod 15, but the hanging degree is made to be extremely small so that the desk plate 1 lowers itself by its own weight. Although it is not possible to apply a slight external force to the desk plate (1) so that it can move up and down, at this time, even if raised or pressed down the desk plate (1) by the force alone, the ruled paper projection (9) of the ruler (11) is fixed Since it is easily detached from the hanging groove 14 of the rod 15, the height can be adjusted freely.

그리고 책상판(1)의 높이 조정이 끝났을때에는 작동키(17)를 아래로 내려 지렛대의 요령으로 작동관(5)을 위로 올리게되면 작동관(5)은 압축되어 있는 스프링(12)의 복귀 탄발력에 의하여 상향으로 탄동되어지면서 이의 대피실(6)속으로 괘착구(11)의 돌연부(7)가 대피되어지게 하고 대피실(6)에 삽입 대피되어진 돌연부(7)는 대피실 (6)내벽에 의하여 내측으로 오무라들면서 이의 괘지 돌연부(9)로 하여금 고정봉(15)을 물게하여 이의 괘지요홈(14)에 완강하게 괘지되어지게 한다.When the height adjustment of the desk plate 1 is finished, when the operating key 17 is lowered and the operating tube 5 is raised by the trick of the lever, the operating tube 5 returns the resilience force of the compressed spring 12. By being pushed upward by the evacuation part 7 into the evacuation chamber 6, the rupture part 7 of the fastener 11 is evacuated and the rupture part 7 inserted into the evacuation room 6 is evacuated (6). As the inner wall is pressed into the inner wall, the ruled portion of the lug 9 causes the fixed rod 15 to bite so as to be rigidly squeezed by the ruled groove 14.

따라서 이때의 고정봉(15)은 괘착구(11)의 괘지돌연부(9)에 완강하게 괘지되어 있기 때문에 책상판(1)이 저절로 눌러내린다거나 요동되지 않는다.Therefore, the fixed rod 15 at this time is firmly hung on the ruled protrusions 9 of the ruled fittings 11, so that the desk plate 1 is not pressed down or rocked by itself.

이와같이된 본 고안은 지주봉(2)의 내관(3)속에 작동관(5)과 괘착구(11)를 장착하고 이 괘착구(11)속에 지지각(4)의 고정봉(15)을 괘탈자재토록 삽설하여 책상판 (1)의 높이를 조절할수 있게 하였으므로 책상판(1)의 높이를 간편하고 신속하게 조정할수 있으며 작동키(17)를 제외한 모든 구조가 지주봉(2)과 지지각(4)속으로 은폐되어 책상 외관이 미려할뿐 아니라 볼트나 너트등에 그 부품이 표출되지 않아 이들 부품이 분실될 우려가 전혀 없으며 대피실(6)에 삽탈되는 괘착구(11)의 완벽한 괘착력에 의하여 책상판(1)이 지지각(4)에서 요동되거나 저절로 눌러내릴 우려가 없는 매우 유용한 고안이다.According to the present invention, the operating tube 5 and the fitting 11 are mounted in the inner tube 3 of the holding rod 2, and the fixing rod 15 of the support angle 4 is swung in the fitting 11. Since the height of the desk plate (1) can be adjusted by inserting materials, it is possible to adjust the height of the desk plate (1) easily and quickly, and all structures except the operation key (17) are supported by the support rod (2) and the support angle (4). The interior of the desk is not only beautiful because it is concealed inside, and the parts are not displayed on the bolts or nuts, so there is no fear that these parts will be lost, and the desk plate can be completely removed by the perfect grip of the fitting 11 inserted into the evacuation room 6. (1) is a very useful design without the risk of oscillating or spontaneously declining at the support angle (4).
