DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating shrinkable shroud in which a metal frame is covered with a resin frame to cover an exposed portion of a metal frame inside a composite window frame mounted on a window opening. The present invention relates to a composite sash sump frame structure for preventing dew condensation by improving the structure.

[0002]

2. Description of the Related Art In recent years, an indoor exposed portion of a metal frame is covered with a resin frame in a composite type sash window frame provided with a resin frame on an indoor exposed portion of a window frame made of a metal frame such as an aluminum sash. Composite sashes containing a pair of sliding sashes are being used. This is because the indoor side of a metal frame or metal frame is covered with a resin whose thermal conductivity is extremely low compared to metal, thereby improving the heat insulation of the sash window and suppressing dew condensation on the indoor side. It aims to improve the design by eliminating the visual coldness of metal frames and metal frames, and by integrating it with interior decoration.

[0003]

However, in the composite type sash window, a resin frame is attached to the entire surface of the exposed portion on the indoor side of the metal frame. When the shoji is closed, a resin frame is attached to the exposed portion of the metal frame indoor side. In this state, the outdoor side frame located behind the indoor side frame cannot be seen from the indoor side. The resin frame was not attached for the reason. However, when a part of the shoji is opened, the metal surface of the outdoor summit that is located behind the indoor summit will be exposed through the inner shoji glass. The appearance of the window sash was extremely bad.
In addition, even if the outdoor summit frame is located behind the indoor summit frame, the thermal conductivity of the partial metal frame is high, and the heat insulation of the sash window is partially reduced. As a result, there was a problem with the function as a composite sash.

On the other hand, the resin frame of the shoji screen in the composite sash is more vulnerable to aging or external impact than the metal frame such as an aluminum sash, and may be discolored or damaged. Came early, and for that,
Resin frames may need to be replaced earlier than metal frames such as aluminum, and when the interior decoration is changed to give the resin frame an integral part of the interior decoration, At the same time, the resin frame may need to be replaced according to the interior decoration. However, conventionally, when the resin frame is replaced, there has been a problem that workability is extremely poor due to the complicated mounting structure of the resin frame.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. In a composite type sash for improving heat insulation and sufficiently preventing dew condensation as a composite type window frame, an indoor side sash is required. A resin cover is also attached to the outdoor sumi frame, which is located behind the joint frame and is not exposed to the indoor side, to improve the heat insulation of the entire shoji frame and, if necessary, remove the resin cover from the metal sum frame. It is an object of the present invention to provide a composite frame structure of a composite sash which can facilitate the removal and replacement of the frame.

Since the present invention has the above configuration, the shoji screen 10
Is partially opened, the indoor side surface of the outdoor summing frame 50 located behind the indoor side summing frame 11d is
However, since the resin cover 60 is attached to the indoor side surface, no metal surface is exposed to the indoor side.
The appearance as a composite window sash can be significantly improved.

To remove the resin cover 60 from the summing frame 50, first remove the upper end block 70 and the lower end block 80 attached to the upper and lower ends of the summing frame 50, and slide the resin cover 60 to remove the aluminum. The resin frame, which is a new new resin vertical frame, is removed from the summing frame 50, which is a sliding frame.

The configuration of the composite sash according to the present embodiment has been described above. As described above, the resin cover 60, the upper end block 70, and the lower end block 80 are basically attached to the summing frame 50 by a fitting structure and a locking structure. Therefore, if these resin frames need to be replaced due to aging or damage due to impact,
Without opening the aluminum frame, the upper block 70 and the lower block 80 are removed from the upper and lower ends of the sump frame 50 which is an aluminum vertical frame, and the resin cover 60 is slid from the sump frame 50 to remove the resin cover 60. Removal and replacement are possible.

The embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the matters described in the above embodiment, and can be changed and improved based on the description in the claims. For example, the resin cover 6
