Description

[0001] The present invention relates to a multipurpose external shading device having an external shading device,

More particularly, the present invention relates to a sun shade device, which is integrated with a window and can be changed into a form of a horizontal light shelf according to a general blind shape and an occupant's demand or an altitude of the sun, The present invention relates to a multipurpose variable outer shade device capable of saving energy and securing a viewpoint.

In the windows of the building, curtains or blinds are installed in the room, or the shade is installed to block or shield the sunlight coming into the room. However, if a curtain or a blind is lowered to cover the sunlight, the outside can not be seen through the window, so that the view may be obstructed and the sunlight entering the room may be blocked.

In addition, the conventional blind is usually located in the opening of the room in the lateral direction or the longitudinal direction of the window frame and is configured to be adjustable by occupants, or it is in the form of a louver having a wide slat on the outside.

Although the technique of converting the direct sunlight into the diffused light by introducing the main beam into the room by controlling the slats of the blinds is effective, the problem of obstructing the view of the windows still occurs as the wide slat angle changes.

Accordingly, there have been various studies for securing the view right when the blind is lowered. Among them, in Publication No. 1991-0000329, a folding blind is introduced and the lower end of the folded blind moves upward, . However, since the blinds in the folded state are always located only on the upper side, there is a problem that the sunlight can not be adjusted to the altitude or the illuminance that changes with time and season.

In addition, in the case of an external awning device, it is attached to a building and used as a concept separated from a window, which is difficult to mass-produce, has a high unit price, and has a disadvantage that a separate frame is required to install the louver.
