Title:
INFLATABLE, RETRACTABLE LIGHT DIFFUSION, SHADING AND THERMAL INSULATION SYSTEM
Document Type and Number:
Japanese Patent JP2017223959
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a system and method for controlling light shading and thermal insulation in a light transmissive structure.SOLUTION: An array of adjacently-positioned, inflatable first tubes is provided, each of the first tubes being inflatable to abut on an inflated adjacent first tube. Each of an array of inflatable second tubes 2 is nested within, and inflatable independent of one of the first tubes. Each of the second tubes is connected to one of the first tubes such that when not inflated, each of the second tubes is flattened within one of the first tubes. When inflated, each of the second tubes abuts on an inflated adjacent second tube via the first tubes. The first tubes are preferably clear, while the second tubes are made of a reflective material.SELECTED DRAWING: Figure 6
