Abstract

PURPOSE:To eliminate interlock connection and provide a shutter of little noise by bending side end parts each other to indoor side, and fixing integratedly the bent sides with each other for a serial connection. CONSTITUTION:At both side end parts facing each other of both of main and sub slats 4, 5, connecting sides 4a, 4b, 5a, 5b are bent and formed respectively to indoor side. The facing connecting sides 4a, 5b and 4b, 5a are connected with each other by an appropriate fixing means such as rivet 10, by which a shutter curtain 1 connected and fixed in serial is formed. Thus, the shutter curtain 1 formed in serial is wound around a winding drum 2 by elastically- deforming the sub slat 5 for curving.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a shutter curtain for use in buildings such as houses and buildings.

[Prior art and problems to be solved by the invention] Generally,
This type of shutter curtain for buildings is wound around a winding drum, for example, and is opened and closed while being guided by guide rails formed on both sides of the opening.

By the way, this shutter curtain needs to be formed so that it can be curved because it is wound from a straight position along a guide rail to a winding drum. They were interlocked together to form a bendable shutter curtain. However, in this case, since there is inevitably a gap and play in the interlock joint, there is a problem that noise is generated when opening/closing or when exposed to wind during closing.

Therefore, attempts have been made to eliminate the gap in the interlock joint, but these methods have the problem of complicating the structure of the interlock joint, and are therefore impractical.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a shutter curtain for buildings that can eliminate these drawbacks. A shutter curtain for a building that opens and closes, and the shutter curtain has main slats made of a rigid material and sub-slats made of an elastic material. It is characterized in that the opposing side edges are bent toward the indoor side, and the bent sides are integrally fixed and connected in a series.

With this configuration, the present invention eliminates the interlock coupling and makes it possible to obtain a low-noise shutter.

[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a shutter curtain for a building shutter, and the shutter curtain 1 is wound around a winding drum 2 installed above an opening, and is wound around a guide rail 3 provided on the left and right sides of the opening. It is configured to open and close up and down when guided.

The shutter curtain 1 has main slats 1 to 4 made of a rigid material such as a metal such as steel or aluminum, or a synthetic resin material used in existing shutter curtains, and a material such as spring steel or synthetic resin material. It is constructed by alternately connecting sub-slats 5 made of a material with elasticity.

In other words, in this embodiment, the main and sub-surface slats are 4.5
Connecting sides 4a, 4b, 5a, 5b are respectively bent toward the indoor side on opposite side edges of the , and these opposing connecting sides 4a, 5b and 4b, 5a are connected with rivets. 10 or the like, thereby forming a series of connected and fixed shutter curtains 1. The series of shutter curtains 1 is formed by elastically deforming the sub-slats 5. It is wound around the winding drum 2 by being curved.

In the embodiment of the present invention configured as described above, the opening and closing of the opening is accomplished by raising and lowering the shutter curtain 1 guided by the guide rail 3. However, the shutter curtain 1 is Unlike when rigid slats are bendably connected by interlocking, there is no gap between the slats, and as a result, the slats do not collide with each other during opening/closing operations or when exposed to wind. It is possible to reliably avoid the generation of noise due to contact, and it is possible to obtain a quiet, low-noise building shutter. Furthermore, since there is no gap between the connecting parts of the slats, it has the advantage of being excellent in fire prevention, smoke prevention, and sound insulation.

Moreover, in this case, when winding on the winding drum 2,
Since the elastic and flexible sub-slats 5 are curved instead of the rigid main slats 4, winding can be carried out in a spiral shape without any problem, similar to the conventional interlock connection.

In this way, the elastic deformation of the sub-slats 5 allows the shutter curtain 1 to be wound in a spiral shape.
Main and sub slats 4.5 are connected together, main and sub slats 1-
4.5 It is only necessary to bend the connecting sides 4a, 4b, 5a, and 5b, which are formed by bending the side edges of the comrades facing each other toward the indoor side, so the connection is not only easy, but also easy. ,
Since the separated ends and connected ends of the slats 4 or 5 are not exposed outdoors, this is of course favorable in terms of appearance;
It has the advantage of being convenient for crime prevention and rust prevention.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the point is that a shutter curtain is formed using rigid main slats and elastic sub-slats, and in that case, adjacent slats The slats may be connected and fixed by bending the opposing side edges of each slat toward the indoor side and fixing the bent sides together to connect them in a series. As in the second embodiment shown in Figure 5,
Bent connection sides 6a, 6 formed on the main and sub-slats 6.7
It would be even more preferable to make b, 7a, and 7b slanted so that the indoor side faces upward, so that the rain can be shut off easily.

Furthermore, patterns such as those shown in FIG. 6 (where solid lines represent main slats and broken lines represent sub-slats) may also be used. In other words, the slat surface of the main slat 4 has a substantially semicircular arc shape (Fig. 6A), the slat surface has a substantially corrugated plate shape (Fig. 6B), and the slat surface has a substantially zigzag shape. (Fig. 6C), slats with roughly uneven slats (Fig. 6D), and slats with various patterns on the slat surface. The one on the side,
A combination of these various main and sub slats, or even a plurality of 4 main slats (three in the drawing)
A sub-slat 5 is interposed between the connected ones (sixth
Figure E), conversely, the main slat is connected between multiple sub-slats 5 (Fig. 6 F), and the width of each main and sub-slat (not in the direction between the opposing guide rails). The width in the guide rail direction) can be set arbitrarily if necessary, and the secondary slat 5 is wider than the main slat 4 (
Various types can be adopted, such as Fig. 6G).

Furthermore, as shown in the pattern diagram of FIG. 7, the storage of the shutter curtain is not limited to winding the shutter curtain in a spiral shape around the winding drum as in the first embodiment described above, but instead using the spiral storage rail 8. Something that can be stored (Figure 7A),
It can be implemented in a variety of ways, such as one that is stored in a horizontal storage rail 9 via a curved rail from the guide rail 3 (FIG. 7B).

[Operations and Effects] In summary, since the present invention is constructed as described above, the shutter curtain has main slats made of a rigid plate material and sub-slats made of an elastic plate material. By integrally connecting the slats with the slats, it is possible to eliminate the interlock joints that were previously required, and there is no gap between adjacent slats. It is possible to avoid the generation of unpleasant noise caused by rubbing or collision between the two, and it is possible to significantly reduce the noise and make it quiet. Furthermore, since there is no gap between adjacent slash sheets, it can greatly contribute to improving fire prevention, smoke prevention, and sound insulation.

Moreover, to connect the slats, it is only necessary to integrally fix the bent sides, which are formed by bending the opposing side edges toward the indoor side. And since the connecting end is not exposed outdoors,
Not only is it desirable in terms of appearance, but it also has the advantage of being extremely convenient in terms of crime prevention and rust prevention.
