Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double louver window in which holders are rotatably attached to both sides of a window frame, and two louver pieces indoor and outdoor are attached to each pair of lateral holders.

[0002]

[Prior art]

 When closed, the double louver window has two indoor and outdoor louver pieces that are attached to each pair of holders in the lateral direction. By creating a heavy shielding surface and forming an air layer between them, it is originally excellent in heat insulation and sound insulation. In order to further improve the characteristics of this double louver window, double glazing may be used as the louver piece. The multi-layer glass has a high heat insulating property and a high sound insulating property by bonding two glass plates inside and outside with a spacer and forming a hollow part inside.

However, since the double glazing is expensive, heavy, and has a large thickness, it is also necessary to make a holder for supporting the large glazing large and sturdy. Therefore, the double louver window has a drawback that it is expensive. In addition, since the double glazing has a large thickness, steps may become noticeable in the upper and lower overlapping parts, and the spacer and end surface treatment of the double glazing may appear on the stepped surface, which may impair the appearance. . In addition, glass louver pieces have poor shape and color variations, which can limit the exterior design of a building.

[Problems to be solved by the device]

 The object of the present invention is to provide a double louver window which is inexpensive, lightweight, and has high heat insulation and sound insulation.

[0005]

[Means for Solving the Problems] A plurality of holders are rotatably supported in a window frame. Two louver pieces, one indoor and two outdoor, are attached to each pair of laterally opposed holders. One of the two louver pieces is a hollow material formed by extruding a resin material, and the other is a glass plate. The hollow material and the glass plate are attached in different steps in the indoor and outdoor directions.

[0006]

[Action]

 Double louver pieces open and close the window opening. Louver pieces made of resin hollow material reduce the weight of the double louver window without compromising the function of the window, improve the degree of freedom in color design, and reduce the cost. The glass louver pieces ensure sound insulation due to their weight and material density.

【Example】

 The figure shows a double louver window 1, in which a plurality of holders 3 are rotatably mounted on both sides of a window frame 2 by a horizontal shaft 4, and each pair of holders 3 (a, A set of louver pieces 5 (a, b) is attached between b). Of the pair of holders 3 (a, b), one holder 3a has a connecting portion 6, and indoor end portions of these connecting portions 6 are rotatably connected to the operation link 7. . The operation link 7 is vertically driven by a manual operation or a driving device, whereby the louver pieces 5 are simultaneously rotated about the horizontal shaft 4 and the double louver window 1 is opened and closed. When the window 1 is closed, the louver pieces 5 (a, b) partially overlap each other and close the opening of the window 1.

The pair of louver pieces 5 (a, b) are arranged in the indoor / outdoor direction, and the louver pieces 5 b on the indoor side are arranged one step higher than the louver pieces 5 a on the outdoor side. In this embodiment, the louver piece 5a on the outdoor side is a hollow material made of resin, has a hollow portion 8 over the entire flat surface, and is transparent. The louver piece 5a is formed by cutting a long polycarbonate resin material extruded and elongated for the louver piece. The molded product of the polycarbonate resin is hard and has sufficient strength and shape retention as the louver piece 5 even if it is hollow.

The cross-sectional shape of the louver piece 5a is designed for a movable louver piece, and a lower concave portion 10 having a protrusion 9 at the tip is formed on the inner side of the lower edge and a concave groove is formed on the outer side of the upper edge. 11 is formed. When the louver piece 5a is closed, the protrusions 9 and the recesses 11 are fitted to each other to prevent wind and rain from entering from the overlapping portion of the louver pieces 5a, 5a. When the operation link 7 is pushed upward in the double louver window 1, each louver piece 5 (a, b) rotates, and the upper edge of the louver piece 5 and the upper edge of the lower louver piece 5 are rotated. The outside is polymerized and the opening of the window 1 is closed.

Since each louver piece 5 (a, b) has a light-transmitting property, outside light can be sufficiently taken in even when the double louver window 1 is closed. In addition, since the outdoor louver piece 5a has the hollow portion 8 and the air layer is formed between the continuous outdoor louver piece 5a and the continuous indoor louver piece 5b, the heat insulating property is improved. The sound insulation is high. Further, since the louver piece 5a on the outdoor side is made of hollow resin, the opening / closing operation of the double louver window 1 is light.

The above is one embodiment, and the present invention is not limited to the illustrated specific configuration. The louver pieces 5 (a, b) arranged indoors and outdoors may have hollow louver pieces 5b made of resin. In this case, the weather resistance condition required for the resin forming the louver piece 5b on the indoor side is relaxed. Since the cross-sectional shape of the extruded resin material can be designed relatively freely, the cross-sectional shape of the resin louver piece 5 can be increased by forming the cross-sectional shape of the outer lower part into a curve that smoothly inclines toward the lower edge. The step between the outer surface of the louver piece 5 and the outer surface of the lower louver piece 5 is connected by a smooth curved surface so that the step can be made inconspicuous.

The holder 3 can also be an injection-molded article of ABS resin. ABS resin has high mechanical strength and good plating and coloring properties. In the case of an injection-molded product, a mounting groove having a shape matching the cross-sectional shape of the louver piece 5 can be simultaneously formed on the surface supporting the louver piece 5, and the end portion of the louver piece 5 can be formed in this groove. If they are fitted and attached via a sealing material or an adhesive that also serves as a seal, the attachment can be secured and the hollow portion 8 of the resin louver piece 5 can be isolated from the outside air. The hollow material molded for the louver piece 5 can be formed not only by extrusion molding but also by blow molding or injection molding, and the molding method is selected according to the shape of the target molded product and the characteristics of the resin. . Also, such a hollow material can be formed by bonding a front member and a back member by injection molding. However, extrusion molding or blow molding is a molding method in which the cross-sectional shape of the molding material is the same at any position, and a large number of louver pieces 5 having the same cross-sectional shape can be easily obtained at low cost.

It is preferable that the hollow portion 8 of the louver piece 5 is shielded from the outside air, and the opening may be shielded with a separate sealing material. However, when the louver piece 5 is mounted on the holder 3, it is shielded at the same time. With this structure, the process of forming the double louver window 1 can be shortened. Synthetic resins that can be used include polyurethane, vinyl chloride, vinylidene chloride, polystyrene, AS resin, ABS resin, methacrylic resin, polyethylene, EVA resin, polypropylene, fluororesin, polyamide, polyacetal, polyphenylene oxide, polycarbonate and fiber plastics. Is.

[Effect of device]

 The heat insulation and sound insulation of the double louver window are improved. The opening and closing operation of the double louver window is light. The double louver window can be constructed at low cost. The cross-sectional shape and coloring of the resin hollow louver pieces can be freely adjusted, and the appearance of the building can be improved.
