DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating sash, and can be used, for example, for a louver window or a fitting window having heat insulating performance.

[0002]

2. Description of the Related Art Conventionally, upper, lower, left and right frame members forming a window frame are formed of a metal indoor member such as aluminum disposed on the indoor side, a metal outdoor member disposed on the outdoor side, and these indoor members. 2. Description of the Related Art A heat insulating sash including a heat insulating member made of synthetic resin such as urethane for connecting an outer member in a longitudinal direction is known.

In such a heat insulating sash, for example, in a louver window, it is necessary to provide a link mechanism and a handle for opening and closing the louver blade near a room near a window frame constituting the louver window. For this reason, the louver blades are arranged closer to the outside of the window frame, that is, outside the heat insulating member of each frame.

[0004]

However, if the louver blades are provided on the outdoor side of the heat insulating member, there are portions of the outdoor members of each frame that are exposed to the indoor space. Similarly, other than the louver window, for example, in a fitting window, depending on the position of the glass, even if it is an outdoor member, a portion exposed to the indoor space may be generated. Such a portion has a low heat due to heat transfer from another portion exposed to the outside air, but also touches the warm air in the room, so that the surface is condensed. For this reason, the condensed water generated by the condensation is exposed to the indoor side, especially in the upper frame which is easily noticeable,
Introspection is spoiled. In addition, there is also a problem that such dew water drops to the indoor side.

An object of the present invention is to provide a heat insulating sash capable of improving the interior appearance even when dew water is generated and preventing the dew water from dropping.

[0006]

The heat insulating sash of the present invention comprises:
The upper frame forming the window frame, the lower frame and the left and right vertical frames are configured to include an indoor member arranged on the indoor side and an outdoor member arranged on the outdoor side and a heat insulating member connecting these indoor and outdoor members, A face material that covers the opening of the window frame is a heat insulating sash arranged outside the heat insulating member of each frame, and is exposed to the indoor space of an outdoor member constituting at least an upper frame of each frame. Almost the entire area in the longitudinal direction of the indoor surface is covered with a heat-insulating cover member, and between the upper frame and the cover member.
An upper frame space formed along the longitudinal direction of the upper frame;
Formed along the longitudinal direction of the vertical frame, communicating with the upper frame space
The condensed water generated in the upper frame space with the vertical frame space
A drainage channel for drainage is formed in the space outside the room . In the present invention, the indoor surface exposed to the indoor space of the outdoor member constituting the upper frame is covered with a heat-insulating cover member, so that the indoor surface is hardly dew-condensed, and even when dew is formed. In addition, by being covered with the cover member, the dew condensation water is not exposed to the indoor side. In addition, it is possible to prevent the dew water from dripping to the indoor side. At this time, since the cover member has a heat insulating property, the cover member itself does not condense.

[0007] Further, since the drainage channel is formed , the condensed water on the exposed indoor surface flows into the vertical frame space through the upper frame space, and then flows down the vertical frame space to form the window frame from the lower side. It is reliably discharged to the outside of the room. Thereby, the accumulation of the dew condensation water in the window frame is suppressed.

[0008] In the heat insulating sash of the present invention,
The indoor surface exposed to the indoor space of the outdoor member constituting the vertical frame may be covered by a cover member having a heat insulating property different from the cover member covering the upper frame. In such a case, not only the upper frame but also the dew condensation water in the vertical frame is hidden, so that the introspection is further improved. At this time, the indoor surface of the outdoor member of the vertical frame is
A gap is provided between the outer member and the bar member.
A drain hole is drilled in the section to connect the gap with the vertical frame space.
It is preferably passed through. In this case, the vertical framed room
If condensation forms on the inner surface, remove the condensation from the gap.
Water can be drained to the outside through the vertical frame space.

The heat-insulating sash of the present invention can be used for various windows such as a fitting window, but is particularly preferably applied to a louver window having a plurality of louver blades.
