The embodiment of FIG. 1 shows an example in which the present invention is applied to a so-called external sash. Figure 4
An example when the present invention is applied to an internal sash or a semi-internal sash is shown. This will be described below.

In this embodiment, the window frame WF is assembled in a rectangular shape by the upper frame 1, the lower frame 2, and the left and right vertical frames 3 as in the conventional window frame. Then, the shutter mounting frame SF is configured as a single frame body by connecting the upper frame 4a, the lower frame 4b, and the left and right side plates 4c in a rectangular shape, and the outdoor side end of the upper frame 4 of the shutter mounting frame. A cover body 5 is openably and closably attached to the portion to form a shutter storage space 6. A gap 7 is formed between the lower end portion of the cover body and the outdoor side end portion of the lower frame 4b and the upper frame of the window frame.

In addition, on the facing surfaces of the outdoor side end portions of both vertical frames 3,
A slat guide rail 30 extending from the lower end of the vertical frame to slightly above the gap 7 is formed, and a winding cylinder 57 around which the shutter 56 is wound is provided in the shutter housing space 6 with a reinforcing mounting member 4d and a bracket 59. It is supported by the side plate 4c through the motor, and the winding cylinder 57 is rotated by a motor (not shown) so that the slats 56a move up and down the outdoor surface of the window along the guide rails 30 to open and close the window. The same as the previous embodiment.

In this embodiment, the shutter mounting frame SF

When 8 is fixed to the locking piece 83, the spring restoring force of the locking piece urges it toward the outside, so that the outdoor side surface of the cover plate 8 is brought into contact with the airtight member and the shutter mounting frame SF is formed. The soundproofing effect and the heat insulating effect are secured between the indoors.

Further, the lid plate 8 can be easily removed by moving it in the direction opposite to that when it is mounted.
When minor repairs (repairs that can be done without removing them from the shutter device) are required for the shutter constituent member 56a, the motor, etc., the cover plate 8 can be easily removed from the indoor side for quick and easy repair. It can be carried out. Remove the cover body 5 from the outdoor side or open it,
When carrying out maintenance and repair, when the window is on the upper floor, there is a risk of falling accidents, but in the sash according to the present embodiment, maintenance and repair cannot be performed unless the cover body 5 is opened. Since it is sufficient to open or remove the cover body 5 only in a limited number of cases, a danger such as a fall accident can be prevented or reduced.

Also in this embodiment, the support shaft 58 of the winding drum 57 is used.
Is installed on the indoor side of the guide rail 30, so that the winding cylinder 57 can be stored above the upper frame 1, and the distance from the indoor end of the window frame WF to the guide rail 30 can be increased. Since it can be made as small as possible, the amount of projection of the shutter mounting frame SF from the outer wall W is small, and the appearance of the sash with a shutter is improved.

In FIG. 4, the support shaft 5 of the winding drum 57 is shown.
Although the reinforcing attachment member 4d for supporting 8 is fixed to the vertical frame 3, if the side plate 4c has sufficient strength, the side plate 4c may directly support the spindle 58 of the winding cylinder. In that case, the locking piece 83 can also be fixed to the indoor end of the side plate 4c.

As described above, in the state where the upper frame 4a, the lower frame 4b, and the side plates 4c form a rectangular frame, the shutter mounting frame SF is provided on the bottom of the lower frame 4b and the upper part of the upper frame 1 of the window frame.
