A middle pillar is erected on the indoor side of the middle portion of the shutter plate in the left-right direction, and between the middle pillar and the high-strength slat, the middle pillar and the high-strength slat are removably engaged with each other and engaged. It is characterized in that a fixing member for fixing the high-strength slat to the middle pillar in the combined state is provided.

According to a second aspect of the present invention, there is provided a shutter frame provided at an opening of a building and having guide rails for supporting both side ends of the shutter plate so as to be able to move up and down, and winding the shutter plate provided above the shutter frame. A shutter box for accommodating the shutter plate, wherein the shutter plate is a high-strength slat in some of the plurality of slats located in the opening height direction middle region when closed, and a chamber at the left-right middle portion of the shutter plate. A middle pillar is erected on the inside, and between the middle pillar and the high-strength slat, the middle pillar and the high-strength slat are removably engaged with each other, and have a high strength against the middle pillar in the engaged state. A fixing member for fixing the slat is provided, and the fixing member is slidably engaged with the high-strength slat in the left-right direction, and can be fixed at an arbitrary position in the height direction of the center pillar. That.

The engagement fitting 120 is like a so-called lock, and as shown in FIG.
A bracket 121 attached to the shutter lower frame 17 by a back plate 122 and a screw 123 can be inserted and engaged.

The shutter 10 is configured such that the high-strength slats 11A can be appropriately fixed to the middle pillar 100 thus erected by a fixing member 200. As shown in FIGS. 3, 6 and 7, the fixing member 200 is formed by connecting a first slide plate 201 and a second slide plate 202 with a screw 203 as a fastening fixture via a spacer 204. .

The first slide plate 201 is engaged with the center pillar 100, and is slidably engaged with the engagement groove 106 in the groove 104 by being inserted into the groove 104 of the middle pillar 100 at one end. And a hook portion 201a which is an engaging portion to be engaged. The other end of the first slide plate 201 is connected to the second slide plate 202 so as to be fastened by screws 203.

The second slide plate 202 is slidably fitted in the back surface groove 11m of the high-strength slat 11A, and has a simple rectangular plate shape. Second slide plate 20
A dovetail-shaped slide engagement groove 11m is formed along the longitudinal direction (left-right direction) on the back surface (inside surface of the room) of the high-strength slat 11A to which 2 is engaged.

A notch (insertion opening) 11c for inserting the second slide plate 202 of the fixing member 200 is provided on the back surface of the high-strength slat 11A. The notch 11c is provided at a position that does not interfere with the center pillar 100.

The fixing member 200 can slide in the left-right direction by fitting the second slide plate 202 into the slide engagement groove 11m of the high-strength slat 11A of the shutter plate 12; Board 20
The one hook portion 201a can be engaged from the side groove 104 of the center pillar 100 to any corresponding position in the longitudinal direction (height direction) of the engaging groove 106. Also, the fixing member 200
Are the second slide plate 202 and the first slide plate 201
Of the first slide plate 201 with respect to the engagement groove 106 of the center pillar 100 by loosely connecting
The first slide plate 201 and the second slide plate 202 can be easily inserted by fastening the screw 203 with a tool (driver).
And the high strength slats 11A of the shutter plate 12 and the middle column 100 can be fixedly joined together.
In addition, the cushioning material 1 made of a soft resin is
07 is preferably provided.

Next, the operation of the shutter having the above configuration will be described. At the time of a strong wind such as a typhoon, first, the shutter plate 12 is rolled down from the shutter head 13 and closed.
The upper and lower engaging fittings 11 are provided on the indoor side of the shutter plate 12.
0, 120 are the upper frame 16 and the lower frame 1 of the shutter frame 14.
7 is engaged with the brackets 111 and 121 of the
Is established. Next, the second slide plate 202 of the fixing member 200 is fitted into the slide engagement groove 11m from the notch 11c on the back surface of the high-strength slat 11A, and the fixing member 200 is slid close to the center pillar 100.

Next, with the screw 203 of the fixing member 200 loosened, the hook portion 201a of the first slide plate 201 is
From the side groove 104 on the side surface of the center pillar 100 to the internal engagement groove 1
06. In this state, the screw 203 is tightened to strongly fasten the first slide plate 201 and the second slide plate 202. Thereby, as shown in FIGS. 6 and 7, the high-strength slats 11A can be fixed to the center pillar 100 via the fixing member 200, and the fluttering of the shutter 12 due to strong wind can be suppressed or prevented.

In this case, since the high-strength slats 11A are fixed to the center column 100 instead of the steel plate slats 11, the shutter 12 can be securely prevented while preventing excessive deformation.
It can suppress fluttering. In addition, since the fixing member 200 can be freely slid with respect to the high-strength slats 11A and the center pillar 100 at the beginning of mounting, regardless of the size of the shutter plate 12 and the height and position of the middle pillar 100. The shutter plate 12 can be securely fixed using the fixing member 200.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the present invention is not limited to the above embodiment, and various design changes and the like can be made without departing from the gist of the present invention. Is possible. For example, the sash 50
It is not limited to the pulling type, but may be a single pulling type or the like.
The shape of the fixing member 200 and the cross-sectional shape of the center pillar 100 can be arbitrarily changed. The fixing member 200 is the center pillar 100
May be engaged with any of the left and right side grooves 104, 104.

Alternatively, two fixing members 200 may be used to engage the fixing members 200 with the left and right side grooves 104, 104 of the center pillar 100, respectively. The number of middle pillars is not limited to one, and a plurality of pillars may be erected at appropriate intervals in the left-right direction. A plurality of fixing members may be used at appropriate intervals (intervals of high-strength slats) in the height direction of the center pillar. Further, in the above-described embodiment, the shutter is combined with the sash, but the shutter alone may not be combined with the sash. In this case, the shutter frame may include at least an upper frame and left and right vertical frames. If the shutter frame does not have a lower frame, the lower end of the middle pillar may be engaged and fixed to a bracket embedded in a concrete foundation or the like.
