Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shutter device provided as a rain door on the outdoor side of a bay window.

[Prior Art] Recently, bay windows of the type that are installed by fitting a finished product in which the window and the roof above the window are integrally assembled into an opening formed in the wall of a building have become popular. ing.

When installing a shutter that serves as a rain door on this type of bay window, a winding shaft around which the shutter curtain is wrapped or a winding shaft 1 to
It is designed to have all the opening/closing devices that rotate it in forward and reverse directions built-in.

In the case of a three-sided bay window consisting of a front window and left and right side windows, the shutter curtains for the left and right side windows are wrapped around the left and right ends of the winding shaft, which is wrapped with the shutter curtain for the front window. Either one end of each winding shaft is connected coaxially (see Utility Model Application Publication No. 1484/1984), or each winding shaft is connected to each winding shaft through the sprocket 1 to transmit the power of the opening/closing machine. They are connected coaxially (see Japanese Utility Model Application Publication No. 141485/1985).

However, Utility Model Application No. 61-141484 and Utility Model Application No. 61
- As seen in Publication No. 141485, when all the winding reshafts and opening/closing machines for winding the shutter curtain are built into the roof of a bay window, only the roof becomes abnormally large and at the same time The bay window mullions that support the weight of the roof had to be made thicker and stronger, which had the disadvantage that the appearance of the bay window was significantly impaired.

Therefore, a winding shaft on which the shutter curtain is wrapped is built into the bottom part of the bay window, and a winding drum and an opening/closing machine for moving it forward and backward are built into the roof. A shutter device was proposed that closed a bay window by rolling up the shutter curtain that had been tested in the past.

[Problems to be Solved by the Invention] According to the rising closing type shutter device having the above configuration, the weight of the shutter curtain that is always applied to the roof is transferred to the Ikebukuro part, so the roof can be made into a lightweight structure. For example, when the device is used in a three-sided bay window where the left and right side windows are in contact with the front window at an angle, called a pay window, the winding shaft installed in the Ikebukuro section below the bay window and the winding drum installed in the roof of the bay window have both axes centered on the same axis. If the shutter curtain is placed on the front surface and unwound from the outdoor side of the winding shaft and is also rolled up on the outdoor side of the winding drum, both the unwinding side and the winding side of the shutter curtain of the winding shaft and winding drum are Because it is on the outside, the distance between the adjacent winding shafts, the unwinding side of the winding drum, and the winding side ends of the front window and side window where the axes intersect at an angle becomes large, thus supporting both ends of the shutter curtain. The problem is that the thickness of the mullion between the front window and the side window to which the guide rail is attached becomes thicker, spoiling the appearance of the bay window. In order to reduce the above-mentioned distance, there is a method of arranging the adjacent winding shafts and winding drums at different heights and wrapping their adjacent ends vertically, and reducing the horizontal distance between the adjacent ends on the outdoor side. This means is possible for the lower winding reshaft 1, but in the upper winding drum, adjacent winding drums at an angle are connected to each other by universal joins 1 or gears, etc., and are rolled up and lowered as one unit. Because of this, it was not possible to adopt the above-mentioned means of making the height different, and there was a problem in that even though the weight of the roof was reduced, the thickness of the mullions could not be reduced.

The present invention was devised to overcome the above-mentioned problems, and the present invention reduces the thickness of the mullion between the windows of a bay window equipped with a shutter device that pulls upward and closes it, thereby improving the appearance of the bay window. The aim is to provide a shutter device that can be refined.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a structure in which a shutter curtain for each window is wrapped around the Ikebukuro portion formed on the lower side of a bay window where a plurality of windows touch each other at an angle. The window winding reshaft 1 is arranged vertically at different levels, and the horizontal distances between adjacent outdoor ends of the winding shafts for each window are close to each other, and the roof part formed above the bay window Then, the mutually connected winding drums for each window are placed on the same plane, and the axial center position of the winding drum for each window is adjusted relative to the axial center position of the winding shaft for each window in the base bag section. Displaced outward and arrange the indoor ends of adjacent winding drums close to each other,
The shutter device is characterized in that the shutter curtain for each window is unwound from the outdoor side of each winding shaft and rolled up from the indoor side of each winding drum.

[Function] By arranging the adjacent winding shafts at different levels, the horizontal distance between the one ends of the adjacent winding shafts on the outdoor unwinding side is brought closer, and the winding shaft of the base bag part is arranged at different levels. The axial center of the winding drum in the Ikebukuro section was shifted to the outdoor side compared to the axial center position of the winding shaft in the Ikebukuro section, and the indoor side was set as the winding side, so the ends of the winding side of the adjacent winding drums were also brought closer to each other. , the distance between the guide rails of adjacent shutter curtains attached to the mullions is reduced, and as a result, it becomes possible to reduce the dimensions of the mullions of adjacent windows.

[Example] The present invention will be described in detail below based on an illustrated example.

In the figure, 5 1 is a bay window consisting of a front window 2 and side windows 3 and 3 on both sides, and the bay window 1 of the embodiment is a three-sided pay window in which side windows 3 and 3 on both sides intersect at an obtuse angle with respect to the front window 2. It is shown. 4 is a roof portion of the bay window 1, and 5 is a pocket portion formed at the bottom of the bay window 1.

The Ikebukuro section 5 has a winding shaft 7 on which a shutter curtain 6 for the front window 2 is wound so as to be unwound from the outdoor side, and a winding shaft 7 on which the shutter curtain 8 for the side windows 3 on both sides is wound so as to be unwound from the outside side. It has a built-in winding shaft 9,
The winding shaft 7 of the shutter curtain 6 for the above-mentioned window and the winding shaft 7 of the shutter curtain 8 for the side window are arranged vertically at different levels, and as shown in FIG. The horizontal distance between the ends of the shafts 7 and 9 on the outdoor side is made close to each other.

On the roof 4 of the bay window 1, there is a shutter for the front window 6.
, a hoisting tram 11 that lifts and closes the shutter curtains 6 and 8 by winding up each pair of band-like hanging strips 10 connected to both left and right ends of each starting end of the side window shutter curtain 8 is pivoted. The driving shaft 12 of the front window shutter curtain 6 and the sliding shaft 13 of the side window shutter curtain 8
The front window sliding shaft 12 and both side sliding shafts 13 and 13 diagonally intersecting with this are connected by a universal joint 14, and are attached to the front window quick-acting shaft 12. The front window drive shaft 12 and the side window drive shaft 13sl3 are integrally driven forward and backward by the opening/closing machine 15.

Here, the roof portion 4 is positioned relative to the axis position of the winding reshafts 7 and 9 for the front window and side windows, respectively, around which the shutter curtains 6 and 8 for the front windows and side windows built in the Ikebukuro portion 5 are wound. Winding drum 1 for front windows and side windows built into
The axial center position of the driving shafts 12 and 13 of No. 1 is displaced forward to the outdoor side, and the outdoor cutting line of each winding shaft 7 and 9 of the base bag portion 5 and the indoor cutting line of the winding drum 11 of the roof portion 4 are The shutter curtains 6 and 8 for the front window and the side window are placed on the winding shaft 7 of the Ikebukuro section 5 so that they are approximately in one vertical plane.
