In addition, in the figure, 16 is an outer glass shoji installed in a sliding manner on the outer window frame S1, 17 is a screen door, and 1
8 is an inner glass shoji installed in the inner window frame body S2 in a sliding manner.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the sash S in this example consists of an outer window frame body S1 made of metal, which is attached to the outdoor surface of the peripheral frame of the window opening W, and an inner window frame body S2, which is fitted inside the peripheral frame. On the indoor side of the outer window frame S1, adjustment edges 1M, 2H, which protrude toward the indoor direction and are continuous in a rectangular shape, are provided.
3J and 3'J, and the inner window frame body S2 is formed into a composite frame body in which a metal shoji sliding frame 4 and a base frame 8 having heat insulation properties are integrally fitted around the outer periphery of the metal shoji sliding frame 4. At the same time, the outdoor side periphery of the window frame body S2 has adjustment edges 1M, 2H, 3 by protruding a part of the base frame 8.
J and 3'J, and the inner window frame body S2 is provided so as to be movable in the inward and outward directions according to the expected width of the peripheral frame. 19, 20, 21, 21' are formed and are provided continuously with the base frame 8 having heat insulating properties, and the frame frame 19, 20, 21, 21' is configured to abut against the interior material 22. . Therefore, the inner window frame body S2 has a sliding surface 9 formed on its outdoor peripheral edge.
Convex edge 9E with D, 10E, 11E, 11'E,
Outer window frame body S1 via 10D, 11F, 11'F
Adjustment edges 1M, 2H, 3J, formed on the indoor side of
Since it is possible to move inward and outward within the peripheral frame within the permissible range of sliding contact with 3'J, the peripheral frame, that is, the lintel 12, window sill 13, and left and right vertical columns 14, 1
Even if there is a variation in the expected width of the window frame 4' in the inner and outer directions, this can be easily absorbed and positioned.
The outer glass shoji 16 and the inner glass shoji 18 are moved to the maximum allowable indoor position of D, 11F, and 11'F.
The soundproofing and heat insulating effects of the sash S can be improved by increasing the distance between the two. In addition, since the outer window frame body S1 and the inner window frame body S2 are connected via the base frame 8 of the inner window frame body S2 having heat insulating properties, both frame bodies S
By blocking the heat transfer between 1 and S2, the generation of condensed water on the indoor side can be significantly reduced. In addition, the inner window frame S
2 is formed into a composite frame body in which a base frame 8 made of, for example, synthetic resin having heat insulating properties and elasticity is fitted around the outer periphery of the shoji sliding frame 4, and the base frame 8 is fitted inside the peripheral frame, so that the periphery The space between the frame and the shoji sliding frame 4 is shielded by the base frame 8, and the transmission of sound is significantly reduced, improving the soundproofing effect. The occurrence of this can be prevented and discomfort can be eliminated. In addition, since the inner window frame body S2 is attached via the base frame 8, its attachment strength is increased, and when the inner glass shoji 18 is opened and closed, the opening and closing sound is not transmitted directly to the peripheral frame, so the opening and closing operation can be performed extremely quietly. obtain.
In particular, since the inner window frame body S2 can be adjusted to move indoors and outdoors, the frame frames 19, 20, 21, which have fitting grooves 19A, 20A, 21A, 21A' into which the interior material 22 fits and abuts. 21' can be provided integrally, so that variations in the thickness of the interior material 22 can be dealt with, for example. In addition, since the heat-insulating base frame 8 and the heat-insulating frame frames 19, 20, 21, and 21' are provided continuously, the indoor edge of the inner window frame body and the contact surface of the window opening peripheral frame are completely covered. No condensation,
In addition, the frame frames 19, 20, 21, and 21' are not cold to the touch, making it more comfortable to live in.

The present invention is a double sash comprising a metal outer window frame body attached to the outdoor surface of a peripheral frame of a window opening, and an inner window frame body fitted inside the peripheral frame. , an adjustment edge protruding toward the indoor direction and continuous in a rectangular shape is formed on the indoor side of the outer window frame body, and the inner window frame body has a metal shoji sliding frame and a base having heat insulation properties on its outer periphery. A composite frame is formed by integrally fitting the inner window frame, and the outdoor periphery of the inner window frame has a part of the base frame protruding and overlaps with the adjustment edge, and the inner window frame The body is provided so as to be movable in the inward and outward directions according to the expected width of the peripheral frame, and a frame frame is formed of a heat insulating member on the indoor side of the inner window frame body and is continuous with the base frame having heat insulating properties. In addition, by configuring the frame to abut against the interior material, even if the expected width of the peripheral frame of the window opening, that is, the lintel, window nozzle, and left and right vertical pillars changes, the inner window The frame body can be moved and adjusted in the inward and outward directions to absorb and position it extremely easily.
In addition, the outer window frame body and the inner window frame body are connected through the base frame of the inner window frame body, which has heat insulating properties, and the entire base frame of the inner window frame body is made of a heat insulating member, so both frames It is possible to significantly reduce condensation on the indoor side by cutting off heat conduction between the windows, and since the inner window frame body can be moved and adjusted indoors and outdoors, it is possible to fit the interior material into the picture frame that abuts it. By providing this, it is possible to cope with variations in the thickness of the interior material, and since the insulating base frame and the insulating frame frame are provided continuously, the indoor edge of the inner window frame body and the window There is no condensation at all on the abutting surface of the peripheral frame of the opening, and the frame frame does not feel cold to the touch, making it possible to improve livability.
