실험대의 높이조절 장치{HEIGHT REGULATER OF EXPERIMENTATION STAND}Height adjustment device of experiment bench {HEIGHT REGULATER OF EXPERIMENTATION STAND}

본 발명은 실험대의 높이조절 장치에 관한 것으로, 더욱 상세하게는 웜이 형성된 손잡이의 회전에 의해 웜휠을 회전시켜 실험대의 높이를 조절함으로써 중량물인 실험대의 높이를 기어의 회전에 의해 조절할 수 있고 높이조절장치가 실험대 다리의 중앙에 형성되어 높이조절장치의 오염 및 부식을 방지할 수 있는 실험대의 높이조절장치에 관한 것이다.The present invention relates to an apparatus for adjusting the height of the bench, and more particularly, by adjusting the height of the bench by adjusting the height of the bench by rotating the worm wheel by the rotation of the handle on which the worm is formed, the height of the bench may be adjusted by the rotation of the gear. The apparatus is formed in the center of the bench legs and relates to the height adjusting device of the bench that can prevent contamination and corrosion of the height adjusting device.

일반적으로 가구에는 수평을 조절하기 위한 수평조절장치 및 상기 수평조절장치의 길이를 연장하여 책상이나 걸상의 높이를 조절하는 높이조절장치가 사용되고 있다.In general, the furniture is used a level adjusting device for adjusting the level and the height adjusting device for adjusting the height of the desk or the stool by extending the length of the horizontal adjusting device.

이러한 높이조절장치는 다양하게 제공되고 있어 성장속도가 빠른 학생들의 체형에 맞게 책상이나 걸상을 사용할 수 있도록 하여 성장기 학생들의 자세를 올바르게 잡아주어 척추가 휘어지거나 성장속도가 저하되는 것을 방지한다.These height adjustment devices are provided in a variety of ways to use the desk or stool to fit the body shape of the fast growing students to correctly hold the posture of the growing students to prevent the spine bent or the growth rate is reduced.

상기와 같은 가구 등에 사용되는 종래의 전형적인 높이조절 장치의 일 예가 도 1에 도시되어 있다.An example of a conventional height adjustment device of the related art used for such furniture and the like is shown in FIG. 1.

도 1에서 부재번호 1은 다리, 2는 조절공, 3은 조절봉, 4는 회전판을 각각 가리킨다.In Figure 1, the member number 1 is a leg, 2 is a control hole, 3 is a control rod, 4 indicates a rotating plate.

이에 도시된 바와 같이 종래의 높이조절장치는 가구의 다리(1)에 형성된 조절공(2)에 회전에 의해 삽입 및 인출되도록 나선이 형성된 조절봉(3)을 상측에 형성하고 하측에는 상기 조절봉(3)을 회전할 수 있도록 회전판(4)을 하측에 형성하였다.As shown in the conventional height adjusting device is formed on the upper side of the adjustment rod (3) is formed spirally so that the insertion and withdrawal by rotation in the adjustment hole (2) formed in the leg (1) of the furniture on the upper side and the adjustment rod on the lower side The rotating plate 4 was formed in the lower side so that (3) could be rotated.

그러나 상기와 같은 높이조절장치는 학교에서 사용하는 개인용 책상이나 걸상과 같이 가벼운 가구의 경우에는 회전판을 회전시키기가 용이하여 높이조절을 쉽게 할 수 있었으나 여러명이 사용하는 실험대나 중량물의 가구의 높이를 조절하기 위해서는 가구의 하중에 의해 회전판의 회전이 쉽지 않아 가구를 들어야 하는 문제점이 있었다.However, the height adjustment device as described above is easy to rotate the rotating plate in the case of light furniture, such as a personal desk or stool used in school, but the height can be easily adjusted, but the height of the furniture of the experiment table or heavy objects used by many people In order to rotate the rotating plate by the load of the furniture is not easy to have a problem to lift the furniture.

따라서, 가구를 일정높이로 들어올려 회전판을 회전시켜야 함으로써 노약자나 어린이는 혼자서 사용할 수 없었다.Therefore, the elderly and children could not be used alone by lifting the furniture to a certain height to rotate the rotating plate.

또한, 상기 높이조절장치가 다리의 하측에 형성되어 청소나 습기에 의한 오염이나 부식에 의해 조절장치가 회전되지 않는 문제점이 있었다.In addition, the height adjustment device is formed on the lower side of the leg has a problem that the adjustment device is not rotated due to contamination or corrosion by cleaning or moisture.

한편, 상기 상부기둥(10)의 하단에는 하부기둥(20)에서 상부기둥(10)이 승하강 할 때 상부기둥(10)과 하부기둥(20)이 일정간격 이격되어 승하강되도록 상부기둥(10)과 하부기둥(20) 사이에 완충편(16)을 개재시킨다.On the other hand, when the upper column 10 is lowered from the lower column 20 at the lower end of the upper column 10, the upper column 10 and the lower column 20 to move up and down at a predetermined interval apart from the upper column 10 ) And a buffer piece 16 between the lower pillar 20.

상기와 같은 완충편(16)은 상부기둥(10) 하단에 형성된 고정돌기(14)가 삽입되어 고정될 수 있는 고정홈(15)을 형성하여 상부기둥(10)의 하단 외측면을 감싸도 록 형성한다.The buffer piece 16 as described above forms a fixing groove 15 through which the fixing protrusion 14 formed at the lower end of the upper pillar 10 can be fixed to surround the lower outer surface of the upper pillar 10. Form.

상기와 같이 구성된 본 발명의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.

먼저, 상부기둥(10)을 하부기둥(10)의 내측에 승하강 되도록 삽입하되 상기 상부기둥(10)에 형성된 높이조절공(13)이 높이조절부(30)의 높이조절돌기(33)에 상입되도록 조립한다.First, the upper column 10 is inserted so as to be raised and lowered on the inner side of the lower column 10, but the height adjusting hole 13 formed in the upper column 10 to the height adjusting projection 33 of the height adjusting unit 30. Assemble to be loaded.

상기와 같은 상부기둥(10)의 고정판(12)에는 실험대 및 가구의 상판(11)을 고정한다.Fixing plate 12 of the upper column 10 as described above to fix the top plate 11 of the experiment table and furniture.

이러한 상태에서 손잡이(36)를 회전시키면 손잡이(36) 단부에 형성된 웜(36)이 회전하면서 상기 웜(36)에 치합되어 있는 웜휠(32)이 회전한다.When the handle 36 is rotated in this state, the worm wheel 32 engaged with the worm 36 rotates while the worm 36 formed at the end of the handle 36 rotates.

이렇게 회전되는 웜휠(32)은 회전축(35)을 회전시켜 상기 회전축(35)에 고정된 높이조절판(34)을 연동시켜 회전하게 된다.The worm wheel 32 rotated in this way rotates the rotating shaft 35 to rotate by interlocking the height adjusting plate 34 fixed to the rotating shaft 35.

이와 같이 회전되는 상기 높이조절판(34)의 높이조절돌기(33)가 높이조절돌기(13)에 삽입된 상태에서 회전하면서 상부기둥(10)을 승하강 시킨다.The height adjusting protrusion 33 of the height adjusting plate 34 rotated as described above is moved up and down while rotating in the state inserted into the height adjusting protrusion 13.

이와 같이 손잡이(37)의 회전방향에 따라 승하강되는 상부기둥(10)에 의해 실험대의 상판이나 가구의 상판의 높이를 조절할 수 있으며 웜(36)과 웜휠(32)의 기어비에 의해 적은 힘으로 상판의 높이를 조절할 수 있다.As such, the height of the upper plate of the bench or the furniture can be adjusted by the upper column 10 which is lowered and lowered according to the rotational direction of the handle 37, and the gear ratio of the worm 36 and the worm wheel 32 is reduced by little force. The height of the top board can be adjusted.
