Next, the operation and effect of the first embodiment configured as described above will be explained.

Now, the sash S of this example includes 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 of the window opening W.
On the indoor side of the outer window frame body S1, connecting edges 1M, 2H, 3J, and 3'J that protrude toward the indoor direction and are continuous in a rectangular shape are formed, and the inner window frame body S2 is a composite frame body in which a metal shoji sliding frame 4 and a heat-insulating base frame 8 are integrally fitted to the outer periphery of the shoji sliding frame 4, and screw receivers are provided on the outer periphery side of the shoji sliding frame 4. 5H and 6G are formed in a protruding shape, and grooves 9C and 10C are formed on the inner circumferential side of the base frame 8 to fit the screw receivers 5H and 6G of the shoji sliding frame 4, and the inner circumferential side of the base frame 8 Shoji sliding frame 4 on the peripheral side
The inner window frame body 4 is formed into a frame by contacting the outer circumferential side surface of the inner window frame body 4 through the screw receivers 5H and 6G, and the outer circumferential side surface of the base frame 8 of the inner window frame body 4 is abutting against the circumferential edge material of the window opening W. Connecting edges and connecting outdoor ends 1M, 2H, 3
The structure is such that it contacts J and 3'J in a superposed manner. Therefore, the inner window frame body S2 has sliding surfaces 9D, 10E, 11E, 1 formed on its outdoor peripheral edge.
Convex edges 9E, 10D, 11F, 1 with 1'E
Since it is possible to move inward and outward within the peripheral frame within the permissible range of sliding contact with the connecting edges 1M, 2H, 3J, and 3'J formed on the indoor side of the outer window frame body S1 via 1'F, the peripheral edge Frame or lintel 12, window sill 1
3 and the left and right vertical columns 14, 14', even if there is a variation in the expected width in the inner and outer directions, this can be easily absorbed and positioned, and the inner window frame body S2
By setting the convex edges 9E, 10D, 11F, and 11'F to the maximum allowable indoor position, the outer glass shoji 1
The soundproofing and heat insulation effects of the sash S can be improved by increasing the distance between the sash 6 and the inner glass shoji 18. 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, which has heat insulating properties, heat transfer between the two frame bodies S1 and S2 is cut off. The generation of condensed water inside can be significantly reduced. The inner window frame body S2 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 on the outer periphery of the shoji sliding frame 4, and is fitted inside the peripheral frame. Since the base frame 8 is installed, the space between the peripheral 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 chattering sound is prevented from being generated by acoustics, thereby eliminating discomfort, and when the inner glass shoji 18 is opened and closed, the opening and closing sound is not directly transmitted to the peripheral frame, so the opening and closing operation can be performed extremely quietly. In addition, the inner window frame body S2
The main body is a base frame 8 having heat insulation properties, and each frame 9, 10, 11, 11' of the base frame 8 is fitted into each frame 5, 6, 7, 7' of a metal shoji sliding frame 4. Each frame S2A, S2B, S2C, S of the complex is attached to the
Since they form 2D, they fit together well, and each of these frames S2A, S2B, S2C,
Since S2D is framed with the screw receivers 5H and 6G and housed with the outer peripheral side of the base frame 8 in contact with the inner peripheral side of the peripheral frame of the window opening W, the inner window frame body S2 and the peripheral frame are The inner window frame body S2 can be stably housed, and even though the base frame 8 having heat insulation properties is used as the main body, it can be framed firmly and a sturdy inner window frame body S2 can be obtained. Since the outer peripheral side of the shoji sliding frame 4 does not directly contact the peripheral material of the window opening W, even if dew condensation occurs on the outer peripheral side of the shoji sliding frame 4, the window opening peripheral material will not get wet. It has many features such as

Next, FIGS. 3 and 4 show a second embodiment of the present invention, and this embodiment includes an upper base member 9, a lower base member 10, and left and right parts of the base frame 8 of the first embodiment. Fitting grooves 19A, 20A, 21A, 21'A into which the interior material 22 is fitted are provided on the indoor side of the vertical base members 11, 11' (only the right side is shown in the plan view of FIG. 3).
The frame portions 19, 20, 21, 21' having
is constructed similarly to the first embodiment. Therefore, this frame portion 19, 20, 21, 21'
By providing this integrally, for example, even if the thickness t of the interior material 22 fluctuates, the variation in the thickness t can be absorbed extremely easily by adjusting the movement of the inner window frame body S2 in the inward and outward directions. At the same time, interior construction can be carried out extremely labor-savingly, and the same effects as in the first embodiment can be obtained.

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. , a rectangular continuous connecting edge is formed on the indoor side of the outer window frame body that protrudes toward the indoor direction, and the inner window frame body includes a metal shoji sliding frame and a base having heat insulation properties on its outer periphery. It is a composite frame body integrally fitted with a frame, in which screw receivers are formed in a protruding manner on the outer circumferential side of the shoji sliding frame, and grooves are formed on the inner circumferential side of the base frame. the screw receivers of the shoji sliding frame are fitted together, and the inner peripheral side surface of the base frame is brought into contact with the outer peripheral side surface of the shoji sliding frame to form a framework for the inner window frame body via the screw receivers, and, The outer peripheral side surface of the base frame of the inner window frame body is in contact with the window opening peripheral material, and the outdoor end is in contact with the connecting edge, so that the outer window frame body is connected to the inner window frame body. In addition to being connected through the base frame of the inner window frame body, which has heat insulating properties, the entire base frame of the inner window frame body is made insulated, thereby blocking heat conduction between both frames and preventing the generation of condensed water on the indoor side. can be significantly reduced. In addition, the inner window frame body is mainly composed of a base frame having heat insulating properties, and each frame of the base frame is attached to each frame of a metal shoji sliding frame in a fitting manner to form each frame of the composite body. The frames of these composites are framed together via screw receivers, and the outer peripheral side of the base frame is placed in contact with the inner peripheral side of the peripheral frame of the window opening W. Therefore, it is possible to obtain a sturdy inner window frame body in which the inner window frame body and the peripheral frame are stably housed, and also, the outer peripheral side of the shoji sliding frame can be used as the peripheral material of the window opening W. Since there is no direct contact, even if dew condensation occurs on the outer peripheral side of the shoji sliding frame, the window opening peripheral material will not get wet.
