Description

  The present invention relates to a solar shading device that shields a light-shielding body such as a person or an exhibition product from sunlight.

  As a conventional solar shading device (balloon-shaped simple umbrella), a plastic film sheet is superimposed on at least the outer peripheral side of a circular plastic film sheet, and the outer peripheral part and inner peripheral part of these two plastic film sheets are heat-melted. To form an annular gas sealing portion, and a gas injection port that can be opened and closed is provided in the gas sealing portion to constitute an umbrella body, and both ends of the plastic film sheet forming a grip portion on the lower surface portion of the umbrella body The gas sealing part is filled with a gas lighter than air and inflated in an annular shape, and a thread is tied together to form an advertising balloon or a simple umbrella (for example, see Patent Document 1).

  As another conventional solar shading device, in an umbrella having a shading member in which a solar cell is formed, a shaft that supports the shading member, and an output terminal provided on the shaft or handle, the solar cell generates power. There is one that takes out the generated power from the output terminal through the shaft of the umbrella (see, for example, Patent Document 2).
