The structure of the storage portion according to the present invention will be described by comparing FIG. 2 with FIG. 9 of the conventional example. As shown in FIG. 9, in the conventional storage structure, the height of the lower case plate 41 ′ is substantially the same as the lower end of the front case plate 42. On the other hand, as is clear from FIG. 2, the height position of the lower case plate 41 is lower than the height position of the lower end (lower surface portion 423) of the front case plate 42 by the dimension H. By disposing the lower case plate 41 below the height position of the lower end of the front case plate 42, the housing side of the shutter curtain winding 32 </ b> A at the lower corner of the housing side of the housing portion of the shutter case 4. An installation space for the switch located obliquely below is formed. The opening / closing machine 33 is arranged in the installation space so that the substantially half of the height dimension of the opening / closing machine 33 is located below the lower end of the front case plate 42 (FIGS. 2, 6, and 7). ).

That is, by changing the height position of the conventional lower surface case plate 41 ′ downward, the opening / closing machine 33 is arranged outside the winding shaft 31 without changing the protruding dimension of the shutter case 4 (storage portion). Made it possible. Furthermore, since the conventional front case plate 42 shown in FIG. 9 can be used as it is as the front case plate 42, the front case plate 42 can be used in common with the conventional case case, and the shutter case can be seen from the outdoor side. The height of 4 looks the same as the conventional one.

By setting the height position of the lower case plate 41 to a position lower than the height position of the lower end (lower surface portion 423) of the front case plate 42 by the dimension H, the lower end of the front case plate 42 and the lower case plate 41 are placed. A space is formed between the tip of the inner lintel 410 and when the shutter is fully opened (of course when the shutter is fully closed), the seat plate 320A at the lower end of the shutter curtain 32 and a part of the slat 320 occupy the space. By blocking, the space cannot be seen from the outdoor side. More specifically, as shown in FIG. 2, when the shutter is fully opened, both longitudinal ends of the lowest slat 320 are located in the guide rail 2, and the lower half of the slat 320 is a front case plate. It extends below the lower surface portion 423 of 42. Further, a seat plate 320 </ b> A extending in the opening width direction is provided at the lower end of the slat 320. When the shutter is fully opened, the stopper 320B provided on the indoor side of the seat plate 320A is in contact with the inner lintel 410 formed at the front end of the lower case plate 41 from the lower side. The lower half of the lowermost slat 320 covers the entire width of the opening so as to cover the indoor side of the space formed between the lower end of the front case plate 42 and the inner lintel 410 at the tip of the lower case plate 41. It extends and closes the space.

In the mode shown in FIG. 2, when the shutter is fully opened, the seat plate 320 </ b> A and a part of the slat 320 at the lower end of the shutter curtain 32 are exposed below the lower surface of the front case plate 42. Further, since the front case plate 42 positioned further on the outdoor side with respect to the exposed seat plate 320A and the slats 320 is an eye-catching part, the appearance of the shutter curtain 4 is the same as the conventional one. When the shutter is fully closed, the appearance from the outdoor side consists of a front case plate 42 having the same configuration as the conventional one and a shutter curtain extending vertically from the lower side of the front case plate 42 to the floor surface. This is the same as the appearance of the shutter storage unit.

When maintenance of the opening / closing machine 33 is performed, the screw S1 is removed to remove the front case plate 42 from the bracket 30 and the upper case plate 40, and then the screw S2 is removed to attach the opening / closing machine 33 together with the mounting piece 37 to the shutter body 3. To remove from the storage. Compared to the maintenance of a conventional shaft built-in switch that requires the take-up shaft itself to be removed from the shutter body, it is less time-consuming.

In the embodiment described above, the guide rail base frame 1 extends further upward beyond the upper end of the guide rail 2 and has a height dimension over the entire height of the shutter device. You may comprise from a member different from a guide rail base frame. FIG. 8 is a view showing another embodiment of the present invention.

A shutter case provided with such a side cover 10 'is known and disclosed in, for example, Japanese Patent Laid-Open No. 8-326447.

A lower case plate 41 is provided between the base frames 1 ′ at positions above the upper ends of the upper portions of the left and right base frames 1 ′. An opening / closing machine 33 is mounted on the lower case plate 41. The opening / closing machine 33 may be supported by a member other than the lower case plate 41. Although the front case plate is not shown in FIG. 8, the height of the lower end of the front case plate is substantially the same as the height of the lower end of the side cover 10 ′. Therefore, the lower surface case plate 41 is disposed below the height position of the lower end of the front case plate, and is obliquely below the housing side of the shutter curtain winding at the lower corner of the housing side of the storage space of the shutter case. An opening / closing machine installation space is formed, and the opening / closing machine 33 is arranged in the installation space so that at least a part of the opening / closing machine is located below the lower end of the front case plate. An inner lintel is formed at the tip of the lower case plate 41, and when the shutter is fully opened, the lower end portion of the shutter curtain closes the space formed between the lower end of the front case plate and the inner lintel.

The present invention can be used for a storage part of a window shutter device.
