Description

DETAILED DESCRIPTION OF THE INVENTION The present invention seeks to provide an energy-saving blind that can be operated to reflect solar heat in the summer and absorb solar heat in the winter, and a window equipped with the same. The present invention will be described in detail below with reference to the embodiment shown in Figure 1. Figure 1 is a sectional view showing an embodiment of the present invention.
In the figure, 1 indicates a wall of a building, and 2I indicates a blind according to the present invention. The blind according to the present invention has a double sash made of an outer window 3 and an inner window 4 fitted with a transparent plate such as glass. The winding drum 5 of the roll blind is placed at the upper part inside the gap.
Attach the front and back rIiJ with solar heat reflective rIf
A sheet 8 having U6 and solar heat absorption properties 7 (see FIG. 2) is suspended downward from the winding drum 5, passed around a vertically movable roll 9, and folded upward, and further,
It goes around a fixed roll 10 provided on the upper part of the outer gM between the inner and outer type of the fI double sash and is folded downward and suspended. In the figure, 11 indicates a T-bottom par attached to the lower end of the sheet.

In the illustrated example, the vertically moving roll 9#'i, the roll F acting as a weight, and the roll blind's sea)8'(r) are tensioned by their own weight.
For example, instead of a weight, this may be a roll pulled downward by a spring.

Furthermore, there are openings 12 for ventilation above and below the outer and inner windows. 15.14.15 will be provided. Further, in order to turn the winding drum 5 +vl+, for example, a lifting cord type rolling machine side (not shown) is provided. Note that 16 in the figure indicates a sliding door provided inside the blind.

The above blind is a roller blind with winding drum 5
Seat 8 of the roller blind
It is possible to direct the solar heat reflecting property 6 towards the outside 911 iff, or to direct the solar heat absorbing property 7 towards the outside of the tube.

For example, in the illustrated L-shaped arrangement, in summer,
When the sheet 8 of the four-wheel blind is lowered by operating the lift cord, the roller blind will be in the state shown in FIG. 3 due to the action of the rolls 9. In this state, the outer surface of the sheet becomes reflective l116 and reflects solar heat.At this time,
If you open the upper and lower openings 12 and 13f of the outer room 3, from K,
The warm air inside the satsushi can be released to the outside,
It can effectively prevent the borrowing of solar heat indoors.
Further, in winter, by lowering the bottom par 11 through the pulley 9 and fixing it at the lowest part of the sash, the roll blind becomes the state shown in FIG. 4. In this state (in which the outer surface of the sheet has an absorbency of 7 and a thick
absorb heat. At this time, the upper and lower openings 14 of the inner chamber 4.
By opening 15'i, it becomes possible to take the warm air inside the satsushi into the room. In addition, when opening the pull blind, the sheet 8 must be wound up using the winding drum 5, as shown in FIGS. 3 and 4. Open as shown by the line.

The embodiments described in detail above are based on the blind of the first invention of the present invention! An example of use in the second invention, Kei equipped with blinds, was shown. However, the blind of the present IHIK1 invention may be simply attached to the window's interior III'K, or may be used between the inside and outside of a double sash having openings only at the top and bottom of the interior.

As mentioned above, in the blind K4° according to the present invention, by operating the roll blind roller provided in the double sash, the front side of the sheet can be turned with the back side facing outward, and for example, in summer By turning the solar heat reflecting tendency of the sheet outward, it effectively prevents solar heat from entering the room, and in winter, by turning the solar heat absorbing tendency of the sheet outward, it absorbs solar heat. By introducing warm air into the room,
A heating effect can be obtained. Although drawings are omitted, the present invention describes a blind installed between the inner and outer windows of a double sash consisting of an outer window and an inner window fitted with a transparent plate such as glass. Alternatively, the blind of the present invention may be replaced with a heat insulating wall such as glass wool.Also, even if the blind of the present invention is attached to the inside window surface of a single-layer sash fitted with a transparent plate such as glass, double or triple air can be used in the window. Since it forms a layer, it has a single-light function and is also excellent in heat retention.
