Abstract

본 발명은 높이 조절이 가능한 흑판의 와이어 장력 조절장치에 관한 것으로, 특히 강의실등의 전방벽면에 고정되는 한쌍의 안내기둥(10)과 ; 이 안내 기둥(10)의 안내로 상하 승강되는 흑판(20)과 ; 이 흑판(20)과 와이어(31)로 연결되어 흑판(20)과 균형을 이루도록 하는 평형추(30)와 ; 상기 안내기둥(10)에 설치되어 와이어(31)의 절곡 이동을 안내하는 풀리(40)와 ; 이 풀리(40)가 회전 자유롭게 축설치되는 지지판(51)을 안내기둥(10)으로부터 위치 이동시켜 와이어(31)의 장력을 조절토록 하는 길이 가변수단(50)이 구비되어, 설치시에도 적합한 장력을 신속하고 정확하게 조절할 수 있을 뿐만 아니라, 사용중 발생하기 쉬운 와이어의 이완 및 풀리의 유격 형성시에도 다시 적절한 상태로 와이어의 장력을 조절할 수가 있어 최적의상태로 흑판의 높이조절이 이루어지도록 하는 등의 매우 유용한 발명인 것이다.The present invention relates to a wire tension control device of the height adjustable black board, in particular a pair of guide pillars (10) fixed to the front wall surface, such as lecture room; Black board 20 which is moved up and down by the guide of the guide pillar (10); A counterweight 30 connected to the blackboard 20 and a wire 31 so as to be in balance with the blackboard 20; A pulley 40 installed at the guide pillar 10 to guide the bending movement of the wire 31; The pulley 40 is provided with a length varying means 50 for adjusting the tension of the wire 31 by moving the support plate 51 on which the shaft is rotatably mounted from the guide pillar 10, and is suitable for installation. Can be adjusted quickly and accurately, and the tension of the wire can be adjusted to the proper state again even when the wire is loosened and the gap of the pulley is formed easily, so that the height of the board can be adjusted optimally. It is a useful invention.
