BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter curtain for an architectural shutter to be installed at an opening of a building.

[0002]

2. Description of the Related Art
The shutter curtain of this type of architectural shutter is formed by interlocking a plurality of slats in a rotatable manner in a series. For this reason, when the shutter curtain is wound and accommodated in the winding drum, the interlock connection portions of the respective slats are not allowed to rub against each other to generate an unpleasant noise, and there is a disadvantage that a smooth opening and closing operation is hindered. Was. Therefore, an integrated shutter curtain has been proposed in which a plurality of reinforcing ribs substantially parallel to the axial direction of the winding drum are formed at appropriate intervals on a single thin sheet material having flexibility. . However, in this case, the ribs may be stretched and deformed by their own weight, resulting in inferior durability.
Since the laminated shutter curtains (ribs and the surface of the shutter curtain) rub against each other, unpleasant noise still occurs and quiet opening / closing operation cannot be performed. In addition, durability of the shutter curtain deteriorates due to friction between the shutter curtains. It was connected.

SUMMARY OF THE INVENTION The present invention has been made in order to provide a shutter curtain for an architectural shutter capable of eliminating these disadvantages in view of the above-mentioned circumstances. In a building shutter in which a shutter curtain that can be wound and housed in a winding drum is formed of a single sheet material having flexibility, the shutter curtain is substantially parallel to the axial direction of the winding drum. While forming a plurality of ribs at appropriate intervals, the rib projecting surface of the shutter curtain covers the projecting ribs,
In addition, a reinforcing member for restricting elongation deformation of the rib across both sides of the rib is mounted. According to the present invention, the durability of the one-piece shutter curtain is significantly improved, and the opening and closing operation can be performed extremely quietly.

[0004]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of an architectural shutter. The shutter curtain 1 is provided in an open position, which is wound and housed on a winding drum 3 in a shutter case 2, and stands upright on both left and right sides of an opening. The shutter curtain 1 of the present invention can be wound on a flexible single sheet metal sheet material. A plurality of reinforcing ribs 1a substantially parallel to the axial direction of the drum 3 are arranged side by side at predetermined intervals. That is, the front surface has a plurality of concave grooves 1b which become wider toward the bottom of the groove, while the back surface has a plurality of ridges 1c which become wider toward the front end.

Reference numeral 5 denotes a resin-made reinforcing member mounted on the plurality of ribs 1a so as to be externally fitted thereto.
Is formed to have a substantially U-shaped cross section so as to cover the entire outer surface of the rib 1c. However, both ends of the reinforcing member 5 opposed to each other are sandwiched between upper and lower sides of the base end (narrow portion) of the rib 1a. Are integrally formed. In other words, the reinforcing member 5 is interposed between the laminations when the shutter curtain is wound up to prevent the shutter curtains 1 from rubbing each other, and to restrict the deformation in the extending direction by sandwiching the rib 1a from above and below. I'm sorry. Reference numeral 5b denotes a protruding piece projecting from the inner bottom of the reinforcing member 5 so as to restrict the deformation of the reinforcing member 5,
Reference numeral 5c denotes an extension that protrudes from both left and right ends of the shutter curtain 1 to prevent the shutter curtain 1 from swaying.

On the other hand, reference numeral 6 denotes an auxiliary member which is fitted into the concave groove 1b. The auxiliary member 6 makes the surface of the shutter curtain 1 substantially flat so as to ensure a good appearance. It is provided to eliminate the inconvenience of accumulation of dust and water.

Incidentally, as the reinforcing member 5, various members having different strengths, shapes, and the like can be adopted.
For example, as in the second embodiment shown in FIG. 5, a double structure of the aggregate 7 mounted on the inside and the cover body 8 mounted on the outside is formed. A filler 10 into which a filler 9 for prevention is injected, and an aggregate 10 integrally having a pair of U-shaped portions 10a respectively fitted to adjacent ribs 1a as in the third embodiment shown in FIG. A structure having a double structure with a cover body 11 covering the aggregate 10 and forming an air space S between the two U-shaped portions 10a. Further, as in the fourth embodiment shown in FIG. And a pair of U-shaped portions 12a each of which is fitted externally to the hollow portion 12a.
It is possible to employ a material in which a filler 13 for preventing crushing deformation is injected into b.

In the embodiment of the present invention configured as described above, a one-piece shutter curtain 1 having flexibility is provided.
Is opened and closed based on the forward and reverse rotations of the winding drum 3, but the reinforcing members 5 are mounted on the plurality of reinforcing ribs 1a formed on the shutter curtain 1 in an outer fitting manner. Therefore, even if the self-weight of the provisional shutter curtain 1 acts, the elongation deformation of the rib 1a is surely restricted. As a result, it is possible to provide excellent durability even though the shutter curtain 1 is a one-piece shutter curtain capable of performing a quiet and smooth opening and closing operation.

Moreover, since the reinforcing member 5 is formed so as to cover the entire rib 1a, the reinforcing member 5 is interposed between the shutter curtains 1 to be laminated during the winding and accommodating, thereby preventing the shutter curtains 1 from rubbing each other. Therefore, it is possible to eliminate the occurrence of uncomfortable sound due to the rubbing of the shutter curtains 1 to enable the shutter to be opened and closed quietly, and to further improve the durability by preventing the wear and damage of the shutter curtain 1. it can.

Further, since the reinforcing member 5 is mounted in an external fitting form, it is excellent in assemblability, and has a different coefficient of thermal expansion as in the case where the reinforcing member 5 is bonded or welded. There is no fear that deformation such as distortion and wrinkles will occur based on
Therefore, a good appearance can be maintained over a long period of time.

Extending portions 5c projecting from the left and right ends of the shutter curtain 1 are provided at the left and right ends of the reinforcing member 5.
Is formed so as to prevent the shutter curtain 1 from oscillating, so that the number of parts can be reduced and the structure can be simplified as compared with the case where a dedicated anti-sway member is provided.

When the aggregate 7 is formed as a separate member as in the second embodiment, the strength of the reinforcing member 5 can be set freely based on the selection of the material of the aggregate 7, so that Can provide various shutter curtains 1 having different strengths.

Further, in the case of mounting over a plurality of adjacent ribs 1a as in the third and fourth embodiments, the number of parts and the number of assembling steps are reduced, which contributes to cost reduction. If possible, a heat insulating layer can be formed by the air layer S and the filler 13 so that the shutter curtain 1 can be provided with a heat insulating function.

The present invention is, of course, not limited to the above-described embodiment. For example, as in the fifth embodiment shown in FIG. 8, the projecting base ends of the ribs 1a are brought into contact with each other. Needless to say, the shutter curtain 1 can be implemented. In this case, there is an advantage that the surface of the shutter curtain 1 can be flattened without attaching any special auxiliary member, and the inconvenience that dust and water accumulate in the rib 1a can be eliminated.

[0015]

In summary, since the present invention is constructed as described above, a plurality of ribs substantially parallel to the axial direction of the winding drum are arranged on a single sheet of flexible thin sheet material. The rib protruding surface is provided with a reinforcing member for restricting the rib from extending and deforming on both sides of the rib. Therefore, it is possible to reliably eliminate the problem that the ribs are stretched and deformed due to the weight of the shutter curtain, and as a result, while being formed in a single sheet in order to perform a quiet and smooth opening and closing operation, It can also have excellent durability.

In addition, when the shutter curtain is wound and housed, the reinforcing members are interposed between the laminated shutter curtains, so that it is possible to avoid friction between the shutter curtains. As a result, it is not possible to quietly open and close the shutter without generating any unpleasant noise, but it is also possible to prevent wear and damage of the shutter curtain due to rubbing, thereby further improving the durability.
