DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous shutter device for a bay window to be installed at an opening of a building such as a house or a building.

[0002]

2. Description of the Related Art In general,
A bay window may be provided at the opening of a building such as a house.
In some cases, a shutter device is incorporated in each of the front window and the side window of such a bay window and connected to each other. In such a case, each shutter device is provided with a driving means for performing opening and closing operations, but in this case, the shutter case cannot be large and a large number of parts are required. There is a problem that becomes.

[0003] In order to enable simultaneous opening and closing of other shutter curtains by one opening / closing drive means, as shown in Japanese Utility Model Laid-Open Publication No. 61-189988, a winding shaft for winding each shutter curtain is connected to a universal joint or the like. Some are linked and connected via a power transmission mechanism such as a bevel gear. However, in such a case, when the winding shaft is arranged indoors from the position of the curtain surface of the shutter curtain, it is necessary to take care that adjacent shutter curtains do not interfere with each other. However, there is a problem that the window has a substantially narrow opening width. For this reason, in the prior art, the winding shaft is disposed so as to be located on the outdoor side of the curtain surface position, and this is used as an eave portion, so that the curtain width can be as wide as possible. However, there are users who dislike buildings with conditions that cannot be built because of restrictions such as those where the eaves protrude greatly from the curtain surface, and those who do not like designs with such eaves that protrude greatly, and users who can be purchased However, there is a problem that the power transmission between the winding shafts becomes more difficult as the bending angle between the adjacent shutter devices becomes smaller.

Therefore, as disclosed in Japanese Utility Model Laid-Open Publication No. 61-185894, it is proposed that the lowermost material of the shutter curtain is connected via a connecting member so that the power transmission of the winding shafts is not required. However, even in this case, no consideration has been given to a point relating to interference between adjacent shutter curtains, and prompt improvement of this point is strongly demanded.

Can be made as small as possible, the substantial opening width of the bay window can be widened, and the feeling of opening is excellent.

[0013]

In summary, since the present invention is configured as described above, a plurality of shutter devices continuously connected to the bay window are integrally connected with the lowermost seat plate via a connecting member, and Since one of the shutter devices is configured as a drive-type winding wheel and the other shutter device is configured as a balance-type winding wheel, the shutter curtain of the drive-type shutter device is opened and closed by a driving unit. Accordingly, the shutter curtain of the balance type shutter device is also opened and closed in connection with this. Further, when the winding wheel of each shutter device is disposed indoors with respect to the curtain surface of the fed shutter curtain, the winding wheels of the drive type shutter device and the balance type shutter device are arranged such that the winding wheel from the curtain surface does not work. By arranging the offset amounts to be different from each other, the winding wheel and the shutter curtain can be prevented from interfering with each other. As a result, it is necessary to project the storage portion of the winding wheel from the curtain surface. It is possible to reduce the size.
