Description

[Detailed description of the invention] The present invention relates to panel shutters installed at entrances and exits of buildings, windows, etc., and the curtain is made up of a number of panels vertically connected in a series and bendable. This relates to a device that is folded and stored in an upper shutter case.

Conventionally, a panel shutter is a curtain made by connecting a large number of panels vertically in a series so as to be bendable, and a panel shutter is placed at the upper end of an opening such as a building entrance or window to wind up the curtain. It consists of a winding shaft mounted inside the shutter case, and guide rails erected on both sides of the opening to guide the curtain up and down. Wind it into a roll on the shaft,
When closing the opening, the curtain is lowered by its own weight.

However, in the case where the curtain is wound into a roll on a winding shaft as described above, since the curtain is made up of a large number of panels connected in a flexible manner,
It is difficult to reduce the winding diameter of the curtain on the winding shaft. For this reason, the height and depth of the shutter case tend to increase.
There is a drawback that it is difficult or impossible to install the shutter in places where there is not enough space above the opening.

The present invention aims to eliminate the inconvenience in view of the above-mentioned conventional situation.When the shutter is opened, the raised curtain is immediately shifted from the vertical direction to the horizontal direction at the top of the opening. At the same time, the curtains can be bent and lined up one after another to be stored in a small space.In addition, by reducing the height and depth of the upper shutter case that stores the curtains, it can be used even in places where the space above the opening is narrow. The object of the present invention is to provide a panel shutter storage device in which the shutter can be easily installed.

The structure of the present invention will be explained with reference to one embodiment shown in FIGS. The bent portions formed on the upper and lower edges of the panel 2 form a continuous pattern in the vertical direction, and
They are releasably engaged in the direction of the arrow,
On the right side of the drawing, it also has excellent waterproof properties.

As shown in FIG. 2, each panel 2 is connected above the center of gravity on both sides via both ends of a connecting rod 3 in which two link members 3' are pivoted in a V-shape so as to be bendable. There is. Then, each node of each of the connecting rods 3, that is, the connecting points 4 with the panels 2 at both ends.
As clearly shown in FIGS. 3 and 4, guide rollers 6 and 7 are rotatably attached to the intermediate bending point 5, respectively. Reference numerals 8 and 8 denote guide rails, which are installed vertically on both sides of the opening of the building, and each guide rail 8, 8 has two guide paths at its front and rear parts. 9 and 10 are formed, so that the guide roller 6 at the connection point 4 is guided to the front guide path 9, and the guide roller 7 at the bending point 5 is guided to the rear guide path 10. Reference numeral 11 denotes an intermediate plate fixed inside the guide rail 8 to form guide paths 9 and 10.

On the other hand, a shutter case 12 for storing the curtain 1 is installed above the opening of the building, and within this shutter case 12, guide rails 8, 8
A storage support rail 13 is formed by bending the intermediate plate 11 at an upwardly extended position and horizontally connecting it to the rear. A winding mechanism 14 for raising and lowering the curtain 1 is provided inside the shutter case 12, and a wire 15 is attached to the panel 2 at the lower end of the curtain 1.
is adapted to be vertically wound up by a winding mechanism 14. Note that the winding mechanism 14 is driven by a motor (not shown).

In the panel shutter configured as described above, when the winding mechanism 14 is driven in the winding direction of the wire 15 to open the curtain 1 that closes the opening of the building, the curtain 1 is moved to the bottom panel 1.
raised from And guide rails 8, 8
At the upper end, the guide rollers 6 pivoted to the connection point 4 are guided to the curved part of the storage support rail 13 in the order they reach this point, so that each panel 2 of the curtain 1 has a direction of movement from vertical to horizontal. Depending on the configuration of the center of gravity, it becomes a suspended posture. At this time, the connecting rods 3 are naturally bent and the panels 2 are stored in a sequentially arranged state. Furthermore, the guide roller 7 pivoted at the bending point 5 disengages from the top of the guide path 10 of the guide rails 8, 8, so the connecting rod 3 lowers the bending point 5 according to the posture of the hanging panel 2. It is stored neatly.

To close an opening in a building, the winding mechanism 14 is released to allow free rotation, and the guide rollers 6 and 7 descend along the guide rail 8 due to the weight of the panel 2, allowing the curtain 1 to close the opening. Department will be closed.

In this way, the curtain 1 stored in the shutter case 12 immediately becomes suspended in the process of transitioning from the upper end of the guide rails 8, 8 to the storage support rail 13, which impedes the rising of subsequent panels from below. The shutter case 12 can be stored in a vertical position in a small space at the rear by the action of the connecting rod 3, so that the height and depth of the shutter case 12 can be reduced. Therefore, even if the depth of the upper part of the opening in the building is narrow, the shutter can be easily installed.

In short, the present invention uses a wire winding mechanism that vertically winds the wire attached to the lower part of the curtain, which is made up of a number of panels connected in a series in the vertical direction. In a panel shutter configured to be horizontally transported and stored in a horizontal direction, both sides of the above-mentioned large number of panels are connected at the upper part of the panel via a connecting rod in which two link members are connected in a bendable manner, and both ends of the connecting rod are connected. At the same time, a guide roller is pivotally attached to the connection point to the panel and an intermediate bending point, and a guide rail for guiding the curtain up and down is divided into two by an intermediate plate, and a guide roller at the connection point and a guide roller at the bending point are attached. Two guide paths are formed to respectively guide the guide rollers, and at the upper part of the guide rail, an intermediate plate is extended to form a storage support rail that moves the guide roller at the connection point from the vertical direction to the horizontal direction. When the shutter is opened, each panel of the raised curtain immediately suspends from the storage support rail at the top of the opening, and does not interfere with the raising of the following panel from below, and continues to move backwards due to the action of the connecting rod. Since the curtains are stored in a vertical position in a small space, the height and depth of the upper shutter case that stores the curtains can be reduced, making it easier to shutter even in places where the space above the opening of a building is narrow. It can be installed and has extremely useful practical effects.
