Description

[Detailed Description of the Invention] The present invention relates to a blind built into a double sash having a roll blind built into the double sash having an inner window and an outer window.

Recently, in the blinds built into such double sashes, solar heat reflective fabric and solar heat absorbing fabric have been used as raw fabric for roll blinds, and in summer, solar heat is reflected and transferred indoors. The blind built into the double sash is designed to reduce the cooling load in the summer and the heating load in the winter by preventing the intrusion of sunlight and absorbing solar heat in the winter and bringing it into the room. Proposed.

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.

In addition, in the blinds built into double sashes as mentioned above, the temperature inside the double sash increases, so the warm air inside the double sashes is released outdoors in the summer, and the temperature inside the double sashes increases. , it is preferable to let this air into the room, but if the raw fabric of the roll blind is stretched inside the double sash, this raw fabric will block the movement of air inside the double sash. , sufficient energy saving effect cannot be obtained. The present invention eliminates the disadvantages of the blinds built into double sashes as described above, achieves both solar heat reflection and absorption effects with a single blind, and facilitates the movement of air within the double sash. Therefore, it is an object of the present invention to provide a blind built into a double sash, which has a simple structure and is inexpensive, which exhibits and obtains an energy-saving effect. In this specification, "built into a double sash" refers to when it is built into a window opening between two sets of inner and outer windows, and when it is built into a window opening between two sets of inner and outer windows, the two sets of inner and outer windows are transparent in one set of windows or shoji. This refers to the case where the plates are installed in the space between the inner and outer translucent plates when they are fitted together.

The blind with a built-in double sash according to the present invention is a blind with a built-in double sash that has a roll blind built into the inside of the double sash with an outer window and an inner window, each having a solar heat reflective property with a length equal to the dimensions of the window. A raw roll blind fabric is formed by integrally connecting the raw fabric part, the solar heat absorbing raw fabric part, and the light transmitting part, and the edges of the solar heat absorbing raw fabric part and the solar heat reflective raw fabric part are connected together. It is characterized by the provision of ventilation holes near the section to allow air to pass through.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. FIG. 1 shows an embodiment of a blind with a built-in double sash according to the present invention.
1 is a blind with a built-in double sash, 2 and 3 are its outer windows, and 4 and 5 are its inner windows. In the illustrated example, the outer windows 2 and 3 and the inner windows 4 and 5 are shown as vertical windows, but if it is possible to form ventilation openings on the top and bottom, they can be double-sided windows on the left and right. or may have other structures.

Reference numeral 6 denotes an upper winding roll of the roll blind, which is attached to the sash upper frame 8 with a bracket (not shown). Similarly, 7 is a lower take-up roll and is attached to the sash lower frame 9 with a bracket (not shown). 11 indicates a raw roll blind cloth.

The roll blind raw cloth 11 is formed by integrally connecting a solar heat-reflecting raw cloth part, a solar heat-absorbing raw cloth part, and a light-transmitting part. A vent hole is formed near the edge of the raw fabric portion to allow air to pass through. Examples of such raw roll blind cloth 11 are shown in FIGS. 2, 3, and 4.

FIG. 2 shows a light-transmitting part made of a transparent material between a solar heat-reflecting raw cloth part 12 whose surface is formed as a solar heat-reflecting surface and a solar heat-absorbing raw cloth part 13 whose surface is formed as a solar heat-absorbing surface. 14 are provided and connected together, and ventilation holes 15 through which air passes are provided near the respective ends of the reflective raw cloth portion 12 and the absorbent raw cloth portion 13. When installed inside a double sash, it can be installed with the reflective or absorbing surface facing outdoors. Further, the lengths of the reflective raw cloth portion 12, the absorbent raw cloth portion 13, and the light-transmitting portion 14 are each equal to the distance between the upper and lower winding rolls.

Note that the reflective surface can be obtained by vapor deposition of aluminum or colored white, and the absorbing surface can be obtained by colored black.

In FIG. 3, instead of providing the light-transmissive portion 14 made of a transparent material as shown in FIG. 2, raw cloth portions 12 and 13 are connected by tape 14', and a light-transmitting gap is formed between them. Fig. 4 shows a mesh part 14'' arranged in place of the light-transmissive part 14 made of a transparent material shown in Fig. 2 and connected together. 1
2 and 13 are each formed shorter than the interval between the upper and lower take-up rolls. Also, Figures 3 and 4
In the case shown in the figure, the raw cloth portions 12, 1 are located far from the tape 14' or the mesh portion 14''.
A ventilation hole 15 for air circulation is formed in 3, and a part of the tape 14' or the mesh part 14'' also serves as a ventilation hole for the raw cloth parts 12 and 13 in the use state.
The 14 side edges of 2 and 13 are preferably reinforced with reinforcing edges 12' and 13'. Next, the function of the blind built into the above-mentioned double sash will be explained.

In the summer, raw cloth for roll blinds11
is wound around the lower take-up roll 7, and the solar heat-reflecting raw cloth portion 12 is placed in a stretched state within the double sash. In this case, the outer windows 2 and 3 are opened to form upper and lower air circulation openings, and the inner windows 4 and 5 are closed. In this case, the air outside the window enters from below the sash as shown by arrow A in the figure.
As it passes through to the top, the warm air inside the satsushi is expelled to the outside, and as shown by arrow B in the figure, the air between the roll blind and the inner window that has been warmed by the roll blind is also transferred to the air provided in the raw fabric of the roll blind. moving through the circulation vents;
As shown by arrow A, the warmed air is expelled to the outside of the sash through the ventilation holes, so the temperature inside the sash decreases and cooling energy can be saved in the summer.

In addition, in winter, the raw cloth 11 of the roll blind is wound around the upper winding roll 6,
The solar heat absorbing raw cloth portion 13 is positioned within the double sash. In this case, the inner windows 4 and 5 are opened to form upper and lower air circulation openings, and the outer windows 2 and 3 are
Keep it closed. Therefore, contrary to the above, when used, the heated indoor air will not escape to the outside, and the roll blind built into the satsui will absorb solar heat, and the heated air inside the satsui will be effectively brought into the room. This allows you to save on heating energy in the winter.

In addition, in addition to the solar heat-absorbing raw fabric part and the solar heat-reflecting raw fabric part, the light-transmitting part is provided because the upper and lower take-up rolls of the roll blind of this invention are always fixed to the upper and lower frames of the satsui. Therefore, when the roll blind is opened to let in appropriate light, by using the light-transmitting part on the window surface, the roll blind can be used in the same state as when the roll blind is opened.

As mentioned above, the present invention has ventilation holes for air ventilation near the edges of the raw fabric of the roll blind, so compared to conventional roll blinds, when built into a double sash, the structure is The double air layer created by the air can be constantly pushed out or brought into the room, providing extremely energy-saving blinds. Since the light-transmitting part is integrated, it can be used throughout the year.
Roller blinds can be used and can be provided at low cost.

Furthermore, since the blind built into the double sash according to the present invention does not require a complicated mechanism and can be constructed using a well-known mechanism, it is easy to operate with fewer breakdowns and has a great effect in use. It is.
