[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash window provided in a building, and more particularly to a sash window having rails such as a sliding window and a sliding window.

[0002]

2. Description of the Related Art In recent years, in order to form a comfortable living space and reduce energy used for cooling and heating to save energy, heat insulation performance of outer walls and fittings has been emphasized. For this reason, as a sash window constituting a window of a building, a heat insulating sash having heat insulating performance is increasingly used.

As such a heat insulating sash, the present applicant disposes a heat insulating material on the sliding window on the inner side of the inner rail in the lower frame of the window frame to conduct heat to the indoor exposed surface of the lower frame. An application for a sash window in which dew condensation is prevented has already been filed (Japanese Patent Laid-Open No. 10-8830).

[0004]

By the way, as for the heat insulating performance required for the heat insulating sash, higher performance is required for further promotion of energy saving.
Sash windows with higher heat insulation performance than conventional sash windows have been required. In particular, when dew condensation occurs, dew condensation adheres to the surface of the lower frame of the sash window and remains, so that the heat insulating performance and the dew-proofing performance of the sash window are improved. Is most important, and therefore, it has been required to further improve the heat insulation performance and dew-proof performance of the lower frame.

[0005] It is an object of the present invention to provide a sash window capable of improving the heat insulating performance and dew-proofing performance of the lower frame.

And a heat insulating member.

In such a sash window, at least the lower frame is provided with a double heat insulating line arranged in the indoor and outdoor directions of the first and second heat insulating members. Insulation performance can be improved compared to a sash window, thereby improving dew-proof performance.

In this case, it is preferable that an outer rail is formed on the outdoor member of the lower frame, and an inner rail is formed on the intermediate member. According to such a configuration, when the inner and outer rails are formed like a sliding window, the first heat insulating member is disposed between the inner and outer rails, and the second heat insulating member is provided on the indoor side of the inner rail.
A heat insulating member can be arranged. Thereby, since the inner rail portion is insulated from the outdoor member, the heat insulating performance and dew-proofing performance of the inner rail portion can be improved, and the heat insulating performance and dew-proofing performance of the entire sash window can be improved as compared with the conventional case. .

The upper frame includes a non-ferrous metal indoor member, an intermediate member, and an outdoor member; a first heat insulating member connecting the outdoor member and the intermediate member; and a second heat insulating member connecting the intermediate member and the indoor member.

[0011] It is preferable that the exposed surface of the window frame exposed to the indoor side when the shoji is closed is covered with a heat insulating cover. If the exposed surface of the window frame is covered with a heat insulating cover, dew condensation on the window frame can be suppressed, and the heat insulating performance of the window frame can be further improved. In particular, when the inner rail is formed on the intermediate member of the lower frame, a part of the intermediate member is exposed to the outside of the room. Dew condensation on the member can be suppressed, and the heat insulation performance of the window frame can be further improved.

Further, it is preferable that the upper surface of each heat insulating member of the lower frame is covered with a cover material. According to such a configuration, the heat insulating member is covered with the cover material and is not exposed, so that the design can be improved. In addition, even when the heat insulating members are provided on the upper frame and the vertical frame, it is preferable to cover the inner surfaces of the openings of the heat insulating members, that is, the surfaces exposed to the indoor side, with a cover material having heat insulating properties.

[0013] Further, in the shoji, it is preferable that each frame is constituted by an outdoor member made of non-ferrous metal and an indoor member made of a heat insulating member made of resin. By using a shoji having an indoor member made of a heat insulating member, the heat insulating performance and dew-proofing performance of the shoji can be improved. Therefore, by forming the sash window in combination with the window frame having excellent heat insulation performance and dew-proof performance, the heat insulation performance and dew-proof performance of the sash window can be further improved.
