TECHNICAL FIELD The present invention relates to a shutter device provided as a shutter on the outdoor side of a bay window.

[Prior Art] Approximately, a bay window of a type in which a completed product in which a window, a roof portion on the window, and the like are integrally assembled is fitted into an opening formed in a wall of a building and installed is popular.

When installing a shutter that is a shutter in this type of bay window,
The roof formed on the window of the bay window is equipped with a winding shaft around which a shutter curtain is wound, a switch for rotating the winding shaft forward and backward, and the like.

When the window surface is a three-sided window consisting of a front window and left and right side windows, the shutter curtains for the left and right side windows are respectively wound around the left and right ends of the winding shaft around which the shutter curtain for the front window is wound. Either one end of each take-up shaft should be coaxially connected (see Japanese Utility Model Laid-Open No. 61-141484), or each drive shaft that transmits the power of the opening / closing machine to each take-up shaft via a sprocket should be coaxially connected. To do
And so on. (See Japanese Utility Model Publication No. 61-141485).

However, as seen in Japanese Utility Model Publication No. 61-141484 and Japanese Utility Model Publication No. 61-141485, when all the winding shafts and the opening and closing machines for winding the shutter curtain on the roof of the bay window are built in, only the roof is abnormal. At the same time, the bay window cubicle that supports the weight of the roof must be thick and sturdy at the same time, so that the appearance of the bay window is significantly impaired.

Therefore, a winding shaft with a shutter curtain wound inside the bay bag of the bay window is built in, a winding drum and an opening / closing device for driving the winding drum forward and backward are built in, and a shutter wound around the winding shaft by the winding drum. A shutter device that winds up the curtain and closes the bay window has also been proposed.

[Problems to be Solved by the Present Invention] According to the ascending / closing shutter device configured as described above, since the weight of the shutter curtain that is constantly applied to the roof is transferred to the bag, the roof can have a lightweight structure. When the shutter device is used for a three-sided bay window in which the left and right side windows are in contact with the front window called bay window at an angle, for example, the winding shaft provided in the bag portion below the bay window and the winding drum provided in the bay window roof part When both shaft centers are arranged on one vertical surface and the shutter curtain unwound from the outdoor side of the winding shaft is also wound up on the outdoor side of the winding drum, the winding side of the shutter curtain of the winding shaft and winding drum Since both winding sides are outdoors, the adjacent winding shaft and winding drive of the front window and side window where the axes intersect at an angle. Unwinding side of the mu,
The distance between the one ends on the winding side becomes large, so that the guide rails that support both ends of the shutter curtain are attached, the upright thickness between the front window and the side windows becomes thicker, and the appearance of the bay window is impaired. There are drawbacks.

Further, in order to reduce the above-mentioned interval, means for arranging adjacent winding shafts and winding drums in different steps so that adjacent one ends are vertically overlapped, and a horizontal interval between adjacent one ends on the outdoor side is reduced. Although this means is possible for the lower take-up shaft, in the upper take-up drum, adjacent take-up drums at an angle are connected to each other by universal joints or gears, etc. However, since the means for changing the above-mentioned steps cannot be adopted, the weight of the roof portion can be reduced, but the thickness of the cube cannot be reduced.

The present invention has been made in view of the above circumstances in order to solve the conventional drawbacks, and an object of the present invention is to stand up between windows of exit windows provided in a shutter device that is pulled up and closed upward. The present invention intends to provide a shutter device capable of reducing the thickness of the window and refining the appearance of the bay window.

[Means for Solving the Problem] In order to solve the problem, the technical means adopted by the present invention are:
Winding shafts for each window with the shutter curtains for each window wound around the bottom bag formed under the bay window where the windows are in contact with each other at different angles. The adjacent outdoor side ends of the shaft are arranged close to each other at a horizontal interval, while the roof part formed above the bay window is wound up with a strip-shaped suspension member connected to the winding start end of each shutter curtain. A winding drum for each window is built in, the winding drums are connected to each other on the same plane, and the winding drum for each window with respect to the axial center position of the winding shaft for each window of the main bag portion. The axial center position of the winding drum is displaced to the outdoor side, the indoor side ends of the adjacent winding drums are arranged close to each other, and the shutter curtain for each window is provided to the outdoor side of each winding shaft via the strip-shaped suspension member. From each roll It is characterized in that as rolling up from the interior side of the lower drum.

[Advantageous Effects of the Invention] Therefore, according to the present invention, the winding shafts of the bag portion are arranged such that the adjacent winding shafts are arranged in different steps, so that one ends of the adjacent winding shafts on the outdoor side unwinding side are adjacent to each other. Of the winding drum on the roof is displaced to the outdoor side with respect to the axial center of the take-up shaft of the bag, and the indoor side is taken as the winding side. The winding side ends of the matching winding drums are also brought close to each other, and the guide rail interval between the adjacent shutter curtains that are vertically mounted is reduced. As a result, the vertical dimension of the doors that fit together can be reduced.
