Abstract

PURPOSE:To eliminate interlock linkage and provide a shutter of low noise by turning up and bending one of connecting sides facing each other further to make an interlocked connecting side. 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 buildings installed 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 a building that can eliminate these shortcomings and points. A shutter curtain for a building that opens and closes a section, and the shutter curtain is made of main slats made of a rigid material and sub-slats made of an elastic material. By bending both side edges of the curtain surface toward the indoor side, and fixing these opposing bent sides together to form a connecting side for connecting them in a series,
The present invention is characterized in that at least one of the mutually opposing connecting sides is further folded back and bent to form an overlapping connecting side.

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

[Example] Next, an example 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 includes a main slat 4 made of a rigid material such as metal such as steel or aluminum, or synthetic resin used in existing shutter curtains, and an elastic material such as spring steel or synthetic resin. It is constructed by alternately connecting sub-slats 5 made of a material having .

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. The shutter curtains 1 are connected by appropriate fixing means such as 15, thereby forming a series of connected and fixed shutter curtains. The lever is curved so that the winding is wound onto the take-up drum 2, but in this embodiment, the connecting sides 4a and 4b on the main slat 4 side are bent inward. It is in a polymerized state.

In the embodiment of the present invention configured as described above, the opening and closing of the opening is achieved by raising and lowering the shutter curtain 1 guided by the guide rail 3, but the shutter curtain 1 is moved by a conventional interlock connection. Unlike the case where rigid slats are connected together in a bendable manner, there is no gap between the slats, and as a result, there is no noise caused by the slats colliding with each other during opening/closing operations or when exposed to wind. The occurrence of noise can be reliably avoided, and a quiet, low-noise building shutter can be obtained. 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.
The connection between the main and sub slats 4.5 is the main and sub slat 4.
．． It is only necessary to bend the connecting sides 4a, 4b, 5a, and 5b of the slats 4a, 4b, 5a, and 5b, which are formed by bending the side weaving parts of the 5 comrades facing each other toward the indoor side. Since the separated end and the connected end of 5 are not exposed outdoors, it is advantageous not only in terms of appearance but also in crime prevention and rust prevention.

In this case, the connecting sides 4a and 4b of the main slat 4 are folded back and overlapped, which is advantageous in terms of strength, so even if the main slat 4 is made thin, There is an advantage that sufficient strength can be ensured at the connecting portion, and the weight of the shutter curtain 1 can be reliably reduced.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but the point is that the shutter curtain is formed using rigid main slats and elastic sub-slats, and in that case, the main and sub-slats are To connect and fix the slats, bend the opposing side edges of each slat toward the indoor side.
The bent sides are integrally fixed and connected in a series, and at that time, at least one of the connecting sides facing each other may be folded back in an overlapping manner. As in the second embodiment shown in the figure, the connecting sides 6a and 6b of the main slat 6 may be bent outward, contrary to the first embodiment. The connection sides 8a and 8b on the side of the sub-slat 8 may be folded back and bent to form an overlapping shape, instead of on the side of the main slat 7 as in the third embodiment.Furthermore, as in the fourth embodiment shown in FIG. 9.10 connection sides 9a, 9b, 10a, 1
The ob may be folded back and bent to make it into a polymer shape, or it may be made into a polymerized form as shown in the fifth embodiment shown in FIG.
．． One of the connecting sides 11b and 12b of the 12 may be made into a polymerized state.

Furthermore, patterns such as those shown in FIG. 9 (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. 9A), the slat surface has a substantially corrugated plate shape (Fig. 9B), and the slat surface has a substantially zigzag shape. (Fig. 9C), slats with roughly uneven slats (Fig. 9D), 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 parts (9th
Figure E), conversely, a main slat is connected between a plurality of sub-slats 5 (Figure 9F), and a main slat.

The width of each secondary slat (width in the direction of the guide rails, not in the direction between opposing guide rails) can be set arbitrarily if necessary, and the secondary slats 5 are wider than the main slats 4. Various types can be adopted, such as the one with the shape (Fig. 9G).

Furthermore, as shown in the pattern diagram in FIG. 10, the storage of the shutter curtain is not limited to winding it in a spiral shape around the winding drum as in the first embodiment described above, but instead winding it in a spiral shape on the storage rail 13. It can be implemented in a variety of ways, such as one that is stored (FIG. 10A), and one that is stored on a horizontal storage rail 14 via a curved rail from the guide rail 3 (FIG. 10B).

[Operations and Effects] In summary, since the present invention is constructed as described above, the shutter curtain has connecting sides of the main slats made of a rigid material and an elastic material. By integrally connecting the connecting side of the secondary slat, the interlock joint that was previously required can be eliminated.
Therefore, there is no gap between adjacent slats, and it is possible to avoid unpleasant noises caused by the slats rubbing against each other or colliding with each other during opening/closing operations or when exposed to wind. This means that the noise can be significantly reduced, making it quieter. Furthermore, since there is no gap between adjacent slats, it can greatly contribute to improving fire prevention, smoke prevention, and sound insulation.

Furthermore, to connect the slats, it is only necessary to integrally fix the connecting sides that are bent toward the indoor side, which not only makes connection easy, but also allows the separated ends and connected ends of the slats to be connected outdoors. Since it is not exposed, it not only has a good appearance, but also has the advantage of being convenient for crime prevention and rust prevention.

Furthermore, since at least one of the connecting sides facing each other is folded back and overlapped, it is possible to make a connection with excellent strength, and as a result, the thickness of the slat can be reduced accordingly. Therefore, there is an advantage that the weight of the shutter curtain can be reduced.
