issue).

However, with these systems, the opening/closing mechanism for raising and lowering the shutter curtain is fixed in the roof above the window frame, so the inspection hole is only provided in the ceiling panel of the bay window, making it difficult to perform maintenance on narrow roofs. Not only was it difficult to work inside the building, but it also had the disadvantage of requiring the ceiling to be dismantled in order to take out the switch.

[Problems to be Solved by the Invention] The present invention has been devised in view of the above-mentioned actual situation to eliminate the drawbacks of the conventional art, and its purpose is to solve the problem of a switchgear installed in a roof. By improving the mounting structure of
It is an object of the present invention to provide a shutter device that can be detachably attached to the upper frame of a bay window and can be easily maintained and inspected.

[Means for Solving the Problems] In order to solve the above problems, the technical means adopted by the present invention is to incorporate a shutter curtain wound around a winding shaft into a base portion formed on the lower side of a bay window. A winding drum for winding up a pair of strips connected to both left and right ends of the winding-side starting end of the shutter curtain, and an opening/closing machine for rotating the winding drum in forward and reverse directions are built into the roof formed above the bay window. In a shutter device comprising guide rails for guiding both left and right ends of the shutter curtain erected in left and right mullions that partition a bay window surface, a support seat for an opening/closing machine is formed on the upper surface of the upper frame of the bay window, and A mounting plate with a falling surface formed on the lower edge is attached to one side of the switch on the indoor side, and by fixing the mounting plate only to the mounting surface of the support seat, the switch can be detachably installed. It is characterized by the fact that it has been established.

[Operation of the Invention] Therefore, according to the present invention, the opening/closing machine can be taken out from inside the roof by simply releasing the fixation between the support seat and the mounting plate from the indoor surface of the roof, which simplifies maintenance and inspection. Work can be done extremely easily. [Example] The configuration of the present invention will be described in detail with respect to an example shown in the drawings. Fig. 1 is an overall perspective view of the bay window, Fig. 2 is a perspective view from the indoor side of another embodiment with the side surfaces at right angles, Fig. 3 is an inner perspective view of its lower part, and Fig. 4 is a cross section of the roof. It is a diagram. In the figure, 1 is a building opening, 2 is a bay window shutter installed in the opening 1, and the bay window shutter 2 is
A three-sided window frame 3 is formed consisting of a front face A and left and right sleeves B and C, and a roof part 4 is disposed on the upper part of the three-sided window frame 3.
At the bottom, a shutter curtain 5a for the front A and a shutter curtain 5 for the left and right sleeves are wound around a winding shaft 5.
Shutter curtains 5a, 5b,
Each winding shaft 7 for winding 5c is pivotally supported with the ends of each shaft positioned vertically, and the front panel 8 of the base bag portion 6 is detachable.

Further, a pair of belt-like bodies 9, 9, .
10... are attached to the strip 9, and a steel belt is used to connect the upper end of each shutter curtain to the winding sleeper shaft 5. The hoisting drum 10 is driven forward and backward by the opening/closing machine 11, and the shutter curtains 5a, 5b
, 5c are mullions 12, 12 erected on the upper surface of the base bag portion 6.
・It ascends and descends while being guided by guide rails 13.13 installed in parallel. In the shutter configured as described above, as shown in FIGS. 4 to 7, in the present invention, an opening/closing mechanism is installed on the upper frame 4a of the roof portion 4 in correspondence with the axial center position of the hoisting drums 10, 10. 11 is provided. As shown in FIG. 6, the support seat 14 is made of a metal plate, and the upper mounting flange 14b is folded up from the central horizontal base 14a, the mounting surface 14c is folded down, and the lower mounting flange 14d is bent. This is what I did. On the other hand, a mounting plate 15 is attached to one side of the switch 11 on the indoor side. As shown in FIG. 7, the mounting plate 15 is a bent metal plate, and has flanges 15b at both ends of a main portion 15a and a flange 15c at the lower side.
A further falling surface 15d is formed on the lower edge of the lower flange 15c.
The falling surface 15d is connected to the indoor mounting surface 14c of the support seat l4 using a screw 16 (also shown as a screw hole).
The main part 15a of the mounting plate 15 is attached to the switch 11 by screws 17 (also shown as screw holes). Reference numeral 18 denotes a bottom plate of the opening/closing machine 11 placed on the central platform 14a of the support seat 14, which supports the opening/closing machine 11 but does not have a fixing function.

Therefore, the switch 11 can be easily accessed through an inspection port (not shown) opened on the indoor side of the roof section 4.
Falling surface 15d of mounting plate 15 and mounting surface 1 of support seat 14
The entire mounting plate 15 can be taken out by simply disassociating the fixing screw 16 from the front surface of the mounting plate 4c.

It should be noted that the configurations of the support seat 14 and the mounting plate 15 are not limited to the above-mentioned embodiments, and may be any configuration that can be easily attached and detached from the indoor side.

[Effects of the Invention] In summary, the present invention includes a shutter curtain wound around a winding shaft built into a base portion formed on the lower side of the bay window, and a roof portion formed on the upper side of the bay window. A winding drum that winds up a pair of strips connected to both left and right ends of the winding-side starting end of the shutter curtain, and an opening/closing machine that rotates the winding drum in forward and reverse directions are built in. In a shutter device in which guide rails are installed to guide the left and right ends of the shutter curtain, a support seat for the opening/closing machine is formed on the upper surface of the upper frame of the bay window, and a lower edge is formed on one indoor side of the opening/closing machine. By attaching a mounting plate with a falling surface to the support seat and fixing the mounting plate only to the mounting surface of the support seat. Since the opening/closing machine is arranged in a removable manner, the mounting structure of the opening/closing machine on the roof is improved as intended, and installation in a narrow space is also easy to remove and install during subsequent maintenance.
