HOISTING DEVICE FOR SHADING MATERIAL OF SOLAR SHADING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lifting code winding device for winding a lifting code on a tapered winding shaft by which the lifting code is wound off the winding shaft smoothly while winding it on the winding shaft without overlapping. SOLUTION: In a hoisting device for a shading material of a solar shading device, the winding shaft 3 whose diameter varies to a taper is rotatably supported by a supporting member 2. The shading material is lifted or lowered by winding the lifting code 13 on a large diameter side of the winding shaft 3 while allowing the code to move sequentially to its small diameter side, or by winding the lifting code 13 off the winding shaft 3. The winding shaft 3 is provided with a tilt regulating means 15 for automatically increasing or decreasing a tilt of the taper according to the increase or decrease in a wound amount of the lifting code 13.
