Abstract

본 발명은 상하방향으로 판서위치를 조정할 수 있는 승하강 칠판이며, 칠판의 각 부분중에서 사용자의 필요에 응하여 상하로 소정거리 만큼 승강시킬 수 있는 승강목적물에 승강균형수단을 연결시켜 이루어진 승하강 칠판에 관한 것으로서, 더욱 상세하게는, 일단이 핀축에 의하여 축지지되, 타단은 자유단으로서 선회가능하도록 된 회동부재에 있어, 이 회동부재의 자유단에는 부하측 로프부재를 통하여 승강가이드수단(30)의 슬라이더(31)에 연결하고, 상기 회동레버(45)의 중간부에는 상기 부하측의 승강목적물의 무게와 균등한 반력을 갖도록 반부하측운동전달수단(46)을 구성하여, 승강목적물의 상하이동에 따른 외력을 회동레버(44)에서 받아, 반부하측운동전달수단(46)에 전하도록 이루어진 승강균형수단을 구비한 것을 특징으로 하며 승강목적물의 직선운동을 회동레버(44)의 원운동으로 변환시킬 매우 유용한 발명이다.The present invention relates to an elevating and lowering chalkboard capable of adjusting the position of a board in a vertical direction and having an elevating and lowering balancing means connected to an elevating and lowering object which can be elevated up and down by a predetermined distance in accordance with the user's needs, And more particularly to a pivoting member whose one end is pivotally supported by a pin shaft and whose other end is pivotable as a free end. The free end of the pivoting member is connected to the free end of the lifting and guiding means 30 Side movement transmitting means 46 is formed at the middle portion of the pivotal lever 45 so as to have a reaction force equal to the weight of the object on the side of the load on the load side, And an elevating balancing means for receiving the external force from the pivoting lever (44) and transmitting it to the half load side motion transmitting means (46) Which is a very useful invention for converting the linear motion into the circular motion of the turning lever 44.
