Abstract:
PROBLEM TO BE SOLVED: To provide a motor-driven solar radiation control apparatus in which interference between an upper lifting body and a lower lifting body which are suspended and supported so as to be lifted/lowered from a head box along lifting/lowering trajectories overlapped with each other, can be blocked while enabling the upper lifting body and the lower lifting body to be lifted independently.SOLUTION: In a motor-driven solar radiation control apparatus, an upper lifting body and a lower lifting body for controlling the quantity of light from the outside of a window are suspended and supported so as to be lifted/lowered from a head box along lifting/lowering trajectories which are overlapped with each other. A motor for lifting/lowering and driving the upper lifting body and the lower lifting body independently is provided within the head box. The motor-driven solar radiation control apparatus comprises control means 22, 16, 24 for blocking the interference between the upper lifting body and the lower lifting body during operations for lifting/lowering the upper lifting body and the lower lifting body.
Abstract:
PROBLEM TO BE SOLVED: To provide a daylighting device for enabling independent lifting of an inner light shelf and a sunlight shielding device that are suspended and supported so as to be lifted along mutually overlapping lifting orbits and allowing easy installation of the inner light shelf and the sunlight shielding device.SOLUTION: A daylighting device has an inner light shelf that is arranged in an upper area of an indoor window surface and allows external light to enter a room by reflecting external light using at least one plate, and a sunlight shielding device capable of adjusting a daylighting amount by lifting sunlight shielding members suspended and supported below the inner light shelf. A winder 5 from which sunlight shielding members 8 are suspended and supported is installed in a head box 1 from which plates 3a to 3f are suspended and supported, the sunlight shielding members 8 are suspended and supported from cords 6, 7 hanging down from the winder 5 below the plates 3a to 3f, and the plates 3a to 3f have through holes to allow insertion of the cords 6, 7.
