Description

The present invention relates to an external shade that is installed on the outside (outdoor side) of an opening such as a glass door or glass window of a building for the purpose of shielding sunlight or blindfolding.

Generally, from the glass door of a building, especially in the summer, strong sunlight enters the room and disturbs the indoor air conditioning environment. Conventional curtains are installed inside the glass door (inside the room) to block out sunlight, but when closed, the room becomes a closed space and not only requires indoor lighting throughout the day, but also the scenery and sunlight are blocked, It was a pressed living space with no sense of openness.

Conventionally, a light-shielding screen is provided on the outdoor side of an opening such as a glass window, and the light-shielding screen is wound or unwound by a winder provided above the opening so that the opening is blocked or released by the light-shielding screen. There was an attached shade. (Patent Document 1)
