2. Description of the Related Art In recent years, a composite type sash window frame having a resin frame on an exposed portion on the indoor side of a window frame made of a metal frame such as an aluminum sash has been used to cover the exposed portion on the indoor side of a metal frame with a resin frame. A composite sash, which is a composite type and houses a pair of sliding sliding doors, is being used. This is to improve the heat insulation of the sash window by covering the indoor side of the metal frame or the metal frame with a resin whose thermal conductivity is extremely lower than that of metal, and to prevent dew condensation on the indoor side. It is intended to improve the design by eliminating the visual coldness of the metal frame and the metal frame and by making it integral with the interior decoration.

[0003]

However, in the composite type sash window, the resin frame is attached to the entire surface of the exposed portion on the indoor side with respect to the metal frame. , The resin frame is attached to the exposed indoor side of the metal frame with the shoji closed, and in this state the outdoor side frame located on the back of the indoor side frame cannot be seen from the indoor side. The resin frame was not attached for the reason. However, when even a part of the shoji screen is opened, the metal surface of the outdoor shoji frame located at the back of the indoor shoji frame will show through the glass of the internal shoji screen. The appearance as a window sash was extremely bad.
In addition, even though the outdoor side wooden frame is located behind the indoor side wooden frame, the thermal conductivity of the metal frame is partially high, and the heat insulation of the sash window is also partially reduced. Then, there was a problem in the function as a composite sash.

On the other hand, the resin frame of the shoji in the composite sash is weak against secular change or shock from the outside as compared with the metal frame such as the aluminum sash and may be discolored or damaged. Came early and, for that reason,
Compared to metal frames such as aluminum, resin frames may need to be replaced earlier, and when the interior decoration is changed in order to make the resin frames integrated with the interior decoration, At the same time, it may be necessary to replace the resin frame according to the interior decoration. However, conventionally, when the resin frame is replaced, there is a problem that workability is extremely poor due to the complicated mounting structure of the resin frame.

The present invention has been made in view of the above-mentioned conventional problems, and in a composite type sash for improving heat insulation as a composite type window frame to sufficiently prevent dew condensation, originally, it is an indoor side sash. A resin cover is also attached to the outdoor side fence which is located at the back of the fence and is not exposed to the indoor side, improving the heat insulation of the entire shoji frame and, if necessary, from the metal cover frame of the resin cover. It is an object of the present invention to provide a combined frame structure of a composite sash that can be easily removed and replaced.

[0006]

In order to achieve the above object, the present invention according to claim 1 is such that the indoor side exposed portion of the metal frame is covered with a resin frame in a composite window frame mounted in the window opening. In a composite sash that accommodates a pair of sliding sliding doors of a composite type, a resin cover can be slidably removed by a fitting mechanism on the indoor side surface of the fitting frame that constitutes the metal vertical frame of the above-mentioned external sliding door. A fixing member composed of a block body having a door stop piece on the upper end side is detachably attached to the upper end of the above-mentioned fitting frame, and the main body of the block body is attached to the hollow part of the main body of the fitting frame. It is characterized in that the block body is fitted and fixed to the fitting frame, and the resin cover can be fixed to the fitting frame by a pressing piece provided on an indoor side portion.
