DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a synthetic resin window frame having a plurality of openings, such as a synthetic resin bay window or a synthetic resin continuous window.

[0002]

2. Description of the Related Art A synthetic resin window has a synthetic resin window frame having a plurality of openings by connecting left and right vertical frames, an upper frame, a lower frame, and a plurality of screens. Glass and shoji are attached to each opening of the window frame. The same applies to synthetic resin windows.

[0003]

As described above, a synthetic resin window frame having a plurality of openings has a long upper frame and a lower frame.
The upper frame and the lower frame are connected to the buns, but the vertical frame, the upper frame,
Since the lower frame and cubicle are made of synthetic resin and have low rigidity, the vertical frame, upper frame, lower frame, and cubicle have been enlarged in the direction of finding in order to improve the strength of the entire window frame. The size of the opening in the finding direction is smaller than the size of the frame in the finding direction, resulting in poor lighting.

Particularly, in the case of a bay window made of synthetic resin, the vertical frame is directly attached to the building frame, but the upper frame and the lower frame are not directly mounted to the building frame, so that the strength of the entire window frame is increased. And it is necessary to increase the size of each frame in the finding direction, so that the above-mentioned problem becomes remarkable.

Accordingly, an object of the present invention is to provide a synthetic resin window frame capable of solving the above-mentioned problems.

[0006]

According to a first aspect of the present invention, an upper frame, a lower frame, and left and right vertical frames made of a synthetic resin are formed in a rectangular frame, and an aluminum frame is formed between the upper frame and the lower frame outside. Are connected to each other to form a plurality of openings, and an indoor vertical member made of synthetic resin is attached to the indoor side surface of the square, and the upper surface of the indoor vertical member is brought into contact with the upper frame room, and the indoor vertical member A window frame made of synthetic resin, wherein the lower surface of the material is in contact with the lower frame chamber.

According to a second aspect of the present invention, the upper and lower frames made of the synthetic resin according to the first aspect of the invention have a shape having an indoor-side inwardly projecting portion on the indoor side of a flat surface facing the expected direction. The connecting metal fittings are fixed to the upper and lower parts of the cubicle, and this connecting metal fitting is fixed to the flat surface of the upper frame and the lower frame, and the cubic is connected to the flat surface of the upper frame and the lower frame. This is a synthetic resin window frame in which the attached synthetic resin indoor vertical member is in contact with the indoor inward projections of the upper frame and the lower frame.

[0008]

According to the first aspect of the present invention, the strength of the window frame is enhanced by the aluminum cubic, so that the size of the synthetic resin upper frame, lower frame, and vertical frame in the direction of finding is reduced. The strength of the frame can be increased.

As a result, the size of the plurality of openings in the synthetic resin window frame in the direction of finding is increased, and the daylighting property is improved.

In addition, since the indoor side vertical member made of synthetic resin is attached to the side surface of the aluminum cubic room, the indoor side surface of the window frame is entirely made of synthetic resin. Does not occur.

According to the second aspect of the present invention, the aluminum cubic is connected to the flat surface closer to the outside of the room than the indoor-side inward projections of the synthetic resin upper and lower frames by the connecting metal fitting. The aluminum cubicle can be firmly connected to the upper and lower frames made of synthetic resin, and the dew condensation water generated on the indoor side of the aluminum cubicle flows down to the flat surface and flows into the room by the indoor inward projection. Can be prevented.
