Description

[Detailed Description of the Invention] The present invention relates to a blind that is attached to the inside of a satsuri room.

In recent years, solar heat reflective fabric and solar heat absorbing fabric have been used for roll blinds to reflect solar heat in the summer and prevent it from entering the room, and to prevent it from entering the room in the winter. Blinds have been proposed that reduce the cooling load in summer and the heating load in winter by absorbing solar heat and introducing the solar heat indoors.

In this way, various mechanisms have been proposed to achieve an energy saving effect by incorporating a roll blind inside a double sash, but a single blind can achieve an energy saving effect throughout the summer and winter. In many cases, it is not possible to achieve this, and if an attempt is made to achieve an energy saving effect throughout the year, the mechanism becomes complicated and large, making it inconvenient for practical use.

The present invention aims to eliminate various drawbacks of conventional blinds and provide a blind that can achieve energy saving effects throughout the year with an extremely simple and inexpensive mechanism.

The blind according to the present invention is a blind installed on the inside of a window room, and includes a mounting part to which a take-up roll of a roll blind is attached to the upper and lower parts or the left and right parts of the inner side of the window room, and an outdoor side of the mounting part. A locking part for locking the tip of the raw fabric of the roll blind is provided on the indoor side, and a solar heat-absorbing raw fabric with a surface that absorbs solar heat is provided on one of the mounting parts on the outdoor side. Install the roll blind take-up roll,
Further, the present invention is characterized in that a take-up roll of a roll blind is attached to the other of the above-mentioned attachment parts, and the winding roll of the roll blind is provided with a solar heat-reflecting fabric whose outdoor side surface is a reflective surface.

The blinds of this invention can be installed on the indoor side of a pair of windows fitted with translucent plates, between the inner and outer windows of a double sash consisting of two sets of inner and outer windows, or between two sets of inner and outer windows in one window frame. Between the inner and outer shoji of double sash with attached shoji,
It is also installed between the inner and outer transparent plates of a double sash made by fitting two sets of inner and outer transparent plates to one window or one shoji.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment in which the blind of the present invention is built into a double sash.

Figures 1 to 3 show an example of a blind built into a double sash according to the present invention. In the figures, 1 is the main body of the double sash, 2 is the upper frame of the double sash, and 3 is the lower part. In the frame, 4 and 5 indicate the inner windows, and 6 and 7 indicate the outer windows.

In the illustrated embodiment, the inner and outer windows are shown as vertical windows, but these may be double-sided windows with ventilation windows above and below them, or may be of any other form. .

Attachment parts 8 and 9 for attaching the take-up roll of the roll blind to the upper and lower parts of the double sash, respectively, and the ends of the raw cloth of the roll blind are secured to the outdoor and indoor sides of the attachment parts. The locking parts 10a, 10b and 11
a and 11b are provided. In the illustrated embodiment, these attachment parts 8 and 9 as well as the locking part 1
0a, 10b and 11a, 11b are respectively attached to the upper frame 2 and lower frame 3 of the double sash.
Separate upper and lower support frames are installed below or above the upper and lower frames at intervals, and the above-mentioned mounting portion and locking portion are attached to these support frames,
A slight gap may be provided above and below the roll blind inside the double sash. in this way,
By creating a gap above and below the roll blind, when you want to exhaust the warm air inside the double sash outside or bring it into the room as described below, it will not be blocked by the raw fabric of the roll blind. allows air to move freely.

Therefore, the take-up roll 13 of the roll blind provided with the solar heat-absorbing fabric 12 is attached to one of the above-mentioned attachment parts 8 and 9, for example, the upper attachment part 8, and the other attachment part, for example, the upper attachment part 8, is attached. Attached to 9 is a take-up roll 15 of a roll blind provided with a solar reflective fabric 14 having a reflective surface on the outdoor side. Note that the solar heat absorption surface can be formed by coloring it black or the like, and the reflection surface can be formed by aluminum vapor deposition or by coloring it white. It would be even better if the indoor side had a color or pattern suitable for indoors. In the figure, reference numerals 16 and 17 refer to operating sections 18 provided at the ends of the raw cloths 12 and 14, respectively.
and 19 represent the operating units 16 and 1, respectively.
The hook-shaped member attached to 7 is shown.

Next, the mode of use of the blind built into the above-mentioned double sash will be explained.

FIG. 1 shows the mode of use in summer. In this case, in the illustrated example, the raw cloth 14 is pulled out from the winding roll 15 of the roll blind provided with the solar heat reflective raw cloth 14 located on the lower side, using the operation unit 17, and the hook at the tip of the raw cloth 14 is pulled out. The shaped member 19 is locked to the upper locking portion 10b. As a result, the solar heat reflective fabric 14 is stretched inside the double sash, thereby preventing solar heat from directly entering the room.

In this case, as shown by the broken line in FIG. 2, the raw cloth 12 is pulled out from the winding cylinder 13 of the roll blind provided with the solar heat-absorbing raw cloth 12 located on the upper side, and the tip of the raw cloth 12 is pulled out as shown by the broken line in FIG. If the hook-shaped member 18 is locked to the lower locking portion 11a, triple air layers are formed within the double sash, increasing the heat insulation effect. In this case, as shown in FIG. 2, if the exterior windows 6 and 7 are opened and ventilation openings are provided at the top and bottom, the solar heat will not be completely reflected by the reflective fabric 14, and the heat will not be completely reflected. Even if the air inside is warm, the warm air is released outside, further increasing the insulation effect. As mentioned above, if a slight gap is provided between the top and bottom of the roll blind and the upper and lower frames of the double sash, this movement of air will be made easier.

Figure 3 shows how it is used in winter. In this case, the raw cloth 12 is pulled out from the take-up roll 13 of the roll blind provided with the solar heat-absorbing raw cloth 12 located on the upper side using the operation unit 16, and the hook-shaped member 18 at the tip thereof is Locking part 11
Lock it to b. As a result, the solar heat-absorbing fabric 12 is stretched inside the double sash, absorbing solar heat and warming the air within the double sash, providing a heating effect. However, at that time,
By opening the inner windows 4 and 5 and providing ventilation openings at the top and bottom, warm air can be taken into the room. In this case as well, if a slight gap is provided between the top and bottom of the roll blind and the upper and lower frames of the double sash, air movement will be made easier.

In addition, at night when solar heat cannot be taken in, as shown by the broken line in FIG.
4 and locking the hook-shaped member 19 at the tip to the upper locking part 10a, a triple air layer is formed within the sash, increasing the heat insulation effect and achieving a heat retention effect in the room. .

As mentioned above, according to the present invention, winding rolls are attached to the upper and lower sides of the indoor side of the sash, so that the fabric that reflects solar heat and the fabric that absorbs solar heat can be changed by a simple operation on the outer surface of the sash. In addition, an air layer can be formed between the raw blind fabrics throughout the summer and winter, resulting in energy saving effects due to the reflection and absorption of solar heat as well as energy saving effects due to the heat insulation effect.

In this example, the winding rolls are arranged above and below the inside of the satsui room to pull out the fabric in the vertical direction. Good too.

In addition, solar heat reflective and absorbent raw cloth 12,
14 can be made of a material that allows light to pass through by 20 to 40%, and during the day, one piece of solar heat reflective or absorbent raw cloth 12 and 14 can be used, and at night, it can be doubled. good.
