Instead of a blind, a slat 31 having a key-breaking cross section is provided in the hollow layer of the double window. It is a thing. However, even in this case, a better heat insulating effect could not be obtained because the metal material was used as the slats.

Therefore, as shown in FIG. 4, it has been proposed to combine the recesses of two U-shaped slats 41 to form a shield, and to enclose a heat insulating material 42 in the hollow to shield the heat. ing. However, since these two metal slats are fixedly joined to each other by a heat insulating material, when there is a temperature difference between them, the lengthwise expansion and contraction of the slats is different, and the warpage of the shield due to heat It had a drawback that it was deformed due to

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a new double window having a shielding effect which has not been heretofore known. is there.

A double window comprising a plurality of shields arranged in a vertical or vertical direction and an opening / closing mechanism for rotating the shields, wherein each shield has a horizontal or vertical length. The two slats each having a length capable of substantially covering the whole and having a substantially U-shaped cross section have U-shaped recesses facing each other without being directly joined through a spacer. The respective shields are connected to the opening / closing mechanism with their ends supported by the supporting member, and each adjacent shield has a U-shaped key portion at its adjacent portion. It is specially arranged so that they are engaged with each other. There is provided a double glazing having the shielding effect of the.

The present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of an essential part showing an example of a double window of the present invention, in which two transparent plate-like bodies 2 face each other with an intermediate layer 9 interposed therebetween. A plurality of shields 11 having shielding performance are provided in the intermediate layer 9, and the shield 11 has U-shaped recesses of the two slats 1 and 1 having a U-shaped cross section facing each other. The slats 1 and 1 are opposed to each other with a spacer 4 interposed therebetween so as not to contact each other.

Further, FIG. 2 shows one end of the shield of the present invention.
FIG. 2A is an enlarged view of a main part showing an example, FIG. 2A shows an example before formation of a shield by slats, and FIG. 2B shows an example after formation. The shield 11 has a support member 3 for rotating the shield 11 at one or both ends thereof.
The shield member 11 is opened and closed by interlocking the support member 3 with an opening / closing mechanism body (not shown) provided in the window frame or the like. A spacer 4 is interposed between the two slats forming the shield 11.
Is fixed to only one of the two slats 1.

Further, the support member 3 is sandwiched between the two slats 1 and a clearance δ is provided between the inner bottom surface of the slat scissor receiving portion 13 of the support member 3 and the end surface of the slat 1. However, the slat 1 is free with respect to the support member 3 in the length direction, and is slidable with respect to expansion and contraction of the slat 1 due to heat.

Here, the shielding body in the present invention is not particularly limited in the arrangement direction as long as it is arranged over substantially the entire surface of the window, but each shielding body having the same specifications can be used. It is preferable to arrange the U-shaped key portions 14 in the horizontal direction or the vertical direction so that the U-shaped key portions 14 can be easily engaged with each other in the adjacent portions of the adjacent shields when closed.

The slat according to the present invention is preferably made of a metal material having good thermal conductivity so that there is no large difference in temperature between the front and back surfaces. It is particularly preferred that The blade structure of this slat has a substantially U-shaped cross section, and the length of this slat has a length that can substantially cover the entire horizontal or vertical length of the window. In consideration of expansion and contraction in the length direction of the slat due to heat, it is preferable that the length is slightly shorter than the length connecting both ends of the window in the horizontal direction or the vertical direction. Further, the slat 1 having a U-shaped cross section may be preliminarily bent into a gentle curved shape in consideration of bending due to its own weight.

Further, in the present invention, the spacers are not particularly limited whether they are provided over the entire length of the slat, are provided so as to be scattered at some places, or are provided at both ends of the slat. Although it is not a matter of course, when the two slats are supported by the supporting member by sandwiching both ends or one end so as to straddle these two slats, in view of the fact that these shapes are stable, the spacers are slats. Are preferably provided at both ends of. As described above, when two spacers are provided in the present invention, each spacer is fixed to only one slat, and in this case, the two spacers may be fixed to the same slat. However, the two spacers may be fixed to separate slats and are not particularly limited, but it is preferable that the two spacers are fixed to separate slats in view of the balance between the two. Furthermore, the slat and spacer that are not fixed are not particularly limited whether they are in contact with each other or not, but it is preferable that they are in contact with each other in order to obtain a shield having a stable shape.

Further, the spacer in the present invention is not limited in its material and the like as long as it has rigidity enough to keep the space between the two slats, but it prevents heat conduction between the two slats. Therefore, it is preferable to use a heat insulating material such as a synthetic resin or an inorganic material, particularly a hard rubber,
It is preferable to use a synthetic resin foam, a heat insulating fiber, or the like.

In this way, the two slats are free with respect to the spacers that are not fixed with respect to the lengthwise direction thereof, and also to the supporting member that has a clearance up to the bottom of the scissor receiving portion. Even if there is a discrepancy in the degree of expansion and contraction due to the temperature difference between the two slats, the shielding itself does not warp without restraining the mutual expansion.

The surface of the slat may be coated with a film having a heat insulating property for changing the thermal emissivity of the shield. For example, the surface of the slat may be coated with an organic paint or the like to obtain a desired heat. By setting the emissivity, the heat insulating effect of the shield can be enhanced. Further, the surface treatment of the slat is not particularly limited to painting as long as the thermal emissivity is changed in order to enhance the heat insulating effect, and the thermal emissivity can be changed by, for example, mirror finishing the slat surface. In this way, by combining these, the heat insulation performance of the shield can be freely set, and the shield can be provided in the middle layer of the double window as a shield of a desired color that is harmonized indoors or outdoors in terms of design. it can.

Further, as the transparent plate used in the present invention, a glass plate such as a single plate glass, a laminated glass, a multi-layer glass and a tempered glass, a synthetic resin plate, or a laminated plate obtained by combining these is used. Be done. As a synthetic resin,
For example, so-called organic transparent resin materials such as polycarbonates, polystyrenes, polymethylmethacrylates, etc. can be used, and at least two or more laminated materials can also be used. Further, these transparent plate-like bodies may have heat ray absorbing performance or heat ray reflecting performance, and may be covered with a desired functional film. In this way, it is possible to obtain a double window having better heat insulation performance by combining with the heat emissivity of the shield that is appropriately determined.
