However, the present invention is not limited to this, and may be in the left-right direction, or may be configured to open and close from below.

For example, an opening / closing body housing is provided with the lower edge of the opening as one side edge, and an opening / closing body such as a shutter curtain is wound and housed in the opening / closing body housing located below the opening. The present invention is also applicable to an opening / closing device that closes an opening by ascending, that is, a so-called rising / closing type opening / closing device. In the case of this configuration, the position of the switch is on the skeleton side (indoor side) of the opening / closing body storage section and on the closing direction side of the opening / closing body. It is arranged at the inner corner, which is the joint.

Further, the opening / closing body housing portion may be arranged with the right edge or the left edge of the opening as one side edge.
That is, the present invention can also be applied to an opening / closing device that opens and closes when an opening / closing body such as a shutter curtain moves in the left and right lateral direction, that is, a horizontal pulling type opening / closing device such as a so-called horizontal pulling shutter device.
In this case, the position of the switchgear is on the skeleton side (indoor side) of the opening / closing body storage section and on the closing direction side of the opening / closing body, and is, for example, a joint portion between the back plate and the side plate of the opening / closing body storage section. Inside corner,

Although the example in which the shutter case 3 is formed in a substantially rectangular box shape by the plate-like members of the bottom plate 9 and the side plate 11 has been described, the opening / closing body storage unit 3 includes an opening / closing body 19 such as a shutter curtain. It may be a space portion that can be stored in a winding state and a winding state, for example, a structure in which a space formed in a part of a wall surface of a building is formed as a storage portion, that is, a winding state in a space portion If the opening / closing body 19 can be housed so as to cover the opening / closing body 19, a hollow portion or a concave portion of the building frame, or a structure in which a lid-like covering member is combined with these spaces may be used. Even in the case of such a structure, as described in the above-described embodiment, the same effect can be obtained by arranging the position of the switch and the position of the open / close body to be wound. .

Further, in the above-described embodiment, the shape of the shutter case 3 as the opening / closing body storage section has a substantially rectangular box shape in cross section. However, the shape of this shutter case (opening / closing body storage section) is arbitrary. Yes, it may be formed in a polygonal shape, a substantially polygonal shape, or the like, and may be configured in any other shape as long as an inner corner is formed at least on the skeleton side (indoor side). Preferably, an inner corner is formed on the opening direction side (shutter curtain) 19 of the opening / closing body (shutter curtain) 19, such as a portion directly above the sash upper frame, which is one side edge of the opening of the building (frame).

Furthermore, in the above-described embodiment, an example was described in which the external shape of the switch 35 was substantially hexagonal prism-shaped. However, the external shape of the switch 35 is not limited to this, and the external shape of the switch 35 may be a substantially square column shape. The shutter case 3 may have a polygonal columnar shape, or any other shape as long as it does not interfere with the shutter curtain (opening / closing body) 19 or the like in the shutter case 3.

Regarding the arrangement of the switch 35 in the shutter case 3, the switch 35 is
Although it has been described as an example in which it is substantially in close contact with the plates 7 and 9 along the inner corner 23 of the base plate 9 and the bottom plate 9, the contact is not necessarily required to be in close contact with each of the plates 7 and 9. A configuration may be adopted in which a gap for the line is provided and arranged slightly obliquely, or a configuration in which a predetermined gap is provided with respect to any of the plate surfaces (the back plate 7 or the bottom plate 9).

Further, in the above-described embodiment, the winding shaft 29 for winding the opening / closing body such as the shutter curtain 19 is provided.
However, both ends are supported via a bearing in the shutter case 3, and the axis as a winding center does not move in the shutter case 3. In the case of a structure in which the axis of 29 does not move,
As described above, the angle θ is generated by the movement trajectory lines G1 and G2 (see FIG. 5) in the state of the minimum winding diameter Ds and the state of the maximum winding diameter Dm. An angle is generated in the introduction to the guide rail 17, but the winding center is moved so as to minimize the angle θ, that is, the winding shaft 29.

As described above, in the structure of the electric wind-up type opening / closing device according to the present invention, the position of the opening / closing device is located at the inner corner at the junction between the back surface and the bottom surface in the opening / closing body housing. Since it is arranged outside the maximum winding diameter of the opening / closing body, the space efficiency in the opening / closing body storage section can be improved, and the opening / closing body storage section can be used more effectively, and the size of the opening / closing body storage section can be reduced.

Then, the top surface,
Positions of the rear, bottom, and front surfaces, positions of the switches arranged in the opening / closing body storage section, positions of these sections and the opening / closing body in a wound state, and guide rails for guiding the opening / closing of the opening / closing body. The opening and closing position of the opening / closing body can be efficiently arranged, so that the dead space in the opening / closing body storage section can be reduced, and the outer shape of the opening / closing body storage section for storing the opening / closing body and the switchgear can be downsized. That is, each dimension, such as the depth dimension of the opening / closing body storage section, can be reduced.

Further, since the winding direction of the opening / closing body is set to the interior side with the inner winding, the projecting direction of the opening / closing body housing portion with respect to the guide rail is the indoor side direction. This makes it possible to reduce the projecting length of the opening / closing body housing from the outer wall with respect to the building outer wall such as the frame.

Further, according to the above arrangement,
Since the position of the inlet that guides the opening / closing body to the guide rail relative to the position where the opening / closing body is wound is configured so as to take into account the height of the switch, the position of the opening is determined from the position of the maximum winding diameter of the opening / closing body. The angle between the moving path line connecting the opening and the moving path line connecting the inlet from the position of the minimum winding diameter becomes shallower, so that the movement of the opening / closing body to the inlet becomes smooth.

Further, according to the configuration in which the winding direction of the opening / closing member is set to the outer winding, the center of the winding shaft is located on the outdoor side of the outer wall of the building such as the frame. The positional relationship of the movement trajectories of the opening and closing body is arranged closer to the indoor side (the skeleton side) than the outer wall. Therefore, the exposed portion can be only the front portion constituting the opening / closing body storage portion, and can be configured in a shape along the maximum winding diameter of the stored opening / closing body, and in consideration of good-looking space saving. It can be configured in a different shape.

Thus, the size of the opening / closing body storage section is reduced, and the arrangement state of the window section or the like in the building opening can be made compact. The function of the retractable opening / closing device can be added to the window portion without providing a structure with a feeling of oppression, and the appearance of the skeleton, for example, the appearance of the building can be improved.

Further, by setting the position of the switchgear arranged in the opening / closing body storage section on the bottom surface in the storage section, the position of the switchgear can be easily reached from the opening side of the building.
The effect of facilitating maintenance work can be obtained. In particular, by adopting a structure in which the front surface and the guide rail are detachable, it is possible to easily perform operations such as taking in and out of the switchgear into and out of the opening / closing body storage section.
