Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIGS. 2 and 3, reference numeral 1 denotes a frame of a building. The frame 1 has an opening 2 for a window. A window sash 3 is attached to the opening 2, and a shutter 4 is provided outside the sash 3 (outdoor side). As the sash 3, a sliding type having sashes 5 a and 5 b that slide open and close in the left-right direction is employed.

The shutter 4 has a shutter frame 6 attached outside the frame 1 so as to surround the periphery of the opening 2.
And a shutter box 7 attached to the upper portion of the shutter frame 6 as described later. In particular, as the shutter 4 of the present embodiment, the shutter frame 6
The sash 3 and the sash frame of the sash 3 are integrally formed.

That is, the shutter frame 6 has the opening 2
A vertical frame 8 fixed to the frame 1 on both sides, and a lower frame 9 joined between lower ends of the vertical frames 8 and fixed to the frame 1 below the opening 2
The vertical frame 8 and the lower frame 9 also serve as the vertical and lower frames of the sash frame. Also, an upper frame (upper frame of a sash frame) 10 fixed to the frame 1 above the opening 2 is located slightly below the upper end of the vertical frame 8 between the upper portions of the vertical frames 8. It is joined by. The shutter box 7 is not placed on the upper part of the upper frame 10. As the vertical frame 8, the lower frame 9, and the upper frame 10, those having a hollow structure (hollow structure) having heat insulation and rigidity are employed.

The shutter box 7 is formed in a horizontally long box shape. The inside of the shutter box 7 is used to wind a shutter plate 11 which is formed by connecting a metal plate (slat) horizontally and elongated in a longitudinal direction. Winding drum 12 is provided. An end plate (end slat) 13 for leading the shutter plate 11 is provided at the tip of the shutter plate 11.
The vertical frame 8 is provided with a guide groove 14 for guiding the end plate portion 13 and both side portions of the shutter plate 11 in the vertical direction. The end plate portion 13 is provided with a stopper portion 15 and the like that comes into contact with the upper frame 10 to stop the end plate portion 13 at the open position when the shutter plate 11 is wound and released.

The shutter box 7 is made of a rigid metal frame 16 as shown in FIGS. 1 to 4, and the outer surface of the frame 16 except for the rear and lower surfaces is made of a synthetic resin cover 17. Covered with.
The shutter box 7 has a rear portion locked to the frame 1 above the vertical frame 8 of the shutter frame 6 via a bracket 18, and lower portions on both sides are placed on an upper end portion of the vertical frame 8. It can be attached by.

0 is provided, and one hook portion 22 for locking the locking hole 21 provided on the rear portion of the shutter box 7 is provided by punching. Also, the bracket 18
The lower end of the tongue is bent so that it can be easily inserted into the hollow portion 23 of the vertical frame 8, and the lower end portion has a tongue-shaped insertion piece 24 inserted into the hollow portion 23.
And a flange 25 that is in contact with the upper end of the vertical frame 8. Thereby, when the bracket 18 is fixed to the frame 1, the positioning of the bracket 18 can be easily performed.

At the lower part on both sides of the shutter box 7, there are provided legs 26 mounted on the upper end of the vertical frame 8. Specifically, the leg portions 26 are provided on both side portions (side frame portions) of the frame 16 of the shutter box 7.
Is formed by bending the lower end portion into an L-shaped cross section.

On both sides of the shutter box 7,
A shutter plate guide 35 made of resin is provided to guide both sides of the shutter plate 11 to be hoisted down (see FIG. 2). As shown in FIG. 7, the shutter plate guide 35 has a guide roller 36 that regulates the position of the shutter plate 11 in the front-rear direction, and a side guide portion 37 that regulates the position of the shutter plate 11 in the left-right direction. ing. The shutter plate guide 35 locks the locking groove 38 provided in the side guide portion 37 with locking pieces (not shown) provided on both side surfaces of the shutter box 7, and screws the front surface of the shutter box 7 with screws. It is fixed.

According to the shutter plate guide 35, when the shutter plate 11 is wound, the winding position does not shift back and forth and right and left, and when the shutter plate 11 is unwound, it is smoothly guided to the guide groove 14 of the shutter frame 6. It becomes possible. Therefore, the winding and unwinding operation of the shutter plate 11 can be performed smoothly despite the structure in which the shutter box 7 and the shutter frame 6 are separated.

In mounting the shutter 4 configured as described above, first, the shutter frame 6 assembled by the upper frame 10, the lower frame 9 and the left and right vertical frames 8 is fixed to a predetermined position of the frame 1 with screws or the like. Next, the insertion piece 24 of the bracket 18 is inserted into the upper end of each vertical frame 8 to position the bracket 18, and then the bracket 18 is fixed to the outer surface of the frame 1 with screws 19.

Next, the rear portion of the shutter box 7 is locked to the hook portion 22 of the bracket 18 via the locking hole 21 and the leg portions 26 on both lower sides of the shutter box 7 are provided.
Is mounted on the upper end of the vertical frame 8 to attach the shutter box 7. The shutter box 7
After the mounting, the extension piece 27 extending to the rear upper edge of the frame 16 of the shutter box 7 is fixed to the frame 1 with screws or the like, as shown in FIG. Is preferred.

According to the shutter 4, a shutter box 7 for winding and storing the shutter plate 11 and a shutter frame 6 for guiding the shutter plate 11 are provided.
The shutter frame 6 including at least the left and right vertical frames 8 is fixed to the frame 1 of the building, and the bracket 18 for locking the rear part of the shutter box 7 is fixed to the frame 1 above the shutter frame 6. Is fixed to the bracket 18 and the lower portions on both sides of the shutter box 7 are placed on the upper end of the vertical frame 8, so that the shutter box 7 can be easily and stably mounted, and the workability is improved. Improvement can be achieved. In this case, only one hook portion 22 is provided on the bracket 18, and the locking hole 21 at the rear of the shutter box 7 may be hooked on a total of two hook portions 22 of the left and right brackets 18. Installation work can be done easily even in high places.

FIGS. 5 and 6 show another embodiment of the present invention, and the same parts as those in the above embodiment are denoted by the same reference numerals. In the shutter 4 of the present embodiment, the shutter frame 6 and the sash frame 28 of the sash 3 are provided.
And are configured separately. The sash frame 28 is assembled in a rectangular shape by an upper frame 29, a lower frame 30 and left and right vertical frames 31, and attached to the opening 2 of the frame 1.

The shutter frame 6 is connected to the sash frame 28
There are left and right vertical frames 8 and a lower frame 9 fixed to the outer surface of the skeleton 1 so as to surround the periphery of the frame 1. A ceiling blind plate 32 is attached between the upper portions of the vertical frames 8 of the shutter frame 6 so as to be located slightly below the upper end of the vertical frame 8 and above the upper frame 29. . Reference numeral 15 denotes a stopper provided on the end plate 13, which is a shutter plate 11.
