Claims (1)
れ、かつロープを巻き付けたリールと、このロー
プを引出す回転方向のみリールにフリクシヨンを
発生させるワンウエイクラツチ付のフリクシヨン
機構と、リールに直結されたドラムとこのドラム
に平行に取付けられた別のドラムとの間に取付け
た定トルクゼンマイとを設けると共に器具重量を
支えるのに前記フリクシヨンと定トルクゼンマイ
の戻し力とを利用してバランスさせることを特徴
とする照明器具等の昇降器。 A reel that is rotatably inserted through a shaft installed in the machine frame and around which a rope is wound, a friction mechanism with a one-way clutch that generates friction on the reel only in the direction of rotation in which the rope is pulled out, and a drum that is directly connected to the reel. A constant torque spring is installed between this drum and another drum installed parallel to the drum, and the weight of the device is balanced by using the friction and the return force of the constant torque spring. Elevators for lighting equipment, etc.
