Abstract

PURPOSE:To eliminate interlock connection and provide a shutter of little noise by forming an engagement groove part open on an adjacent slat side in one of side end parts, and engaging the other side end part with the engagement groove part and locking it for a serial connection. CONSTITUTION:Adjacent engagement groove parts 4a, 4b whose sub slat 5 side is open are formed integratedly at both the side ends of a main slat 4. The lower side end part of the sub slat 5 is pressed into the upper engagement groove part 4a of the main slat of the main slat 4, and the upper end part of the sub slat 5 is pressed into the lower engagement groove part 4b respectively until respective engagement pieces 5a are engaged with an engagement hole 4c for engagement, by which a serial of fixing connection is made so as to make no dropping-off. A shutter curtain 1 formed in serial is wound around a wiring 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 for a building that can eliminate these drawbacks. There is a shutter curtain for a building that opens and closes an opening, and the shutter curtain is made of a main slat made of a rigid material and a sub-slat made of an elastic material. At least one of the mutually opposing side edges of each of these slats is formed with a fitting groove that opens toward the adjacent slat, and the other side edge is fitted and locked into the fitting groove to form a continuous shape. It is characterized by being connected to.

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 fitting grooves 4a are provided at both side edges of the main slat 4 and are open on the side of the adjacent sub-slat 5.
, 4b are integrally formed, and this fitting groove 4a
The shutter curtain 1 is connected in a series by fitting and locking the side edges of the sub-slats 5 to the fitting grooves 4a and 4b, but the mechanism for preventing the sub-slats 5 from coming out from the fitting grooves 4a and 4b is as follows. , in this embodiment, is as follows. In other words, on the indoor sides of the fitting grooves 4a and 4b, the engagement holes 4c are bored with an interval of pinch A. ) is set to B.

On the other hand, engagement pieces 5a are formed by stamping on both side edges of the sub-slat 5. The pitch of the engagement pieces 5a is set to be approximately half (B/2) of the length of the engagement hole 4c.

The shutter curtain 1 then engages the lower edge of the sub-slat 5 with the upper fitting groove 4a of the main slats 1-4, and the upper edge of the sub-slat 1-5 with the lower fitting groove 4b, respectively. By pushing the piece 5a into the engagement hole 4c and fitting it, the shutter curtain 1 can be connected and fixed in a continuous manner in a state where it is prevented from coming out. The slat 5 is elastically deformed and curved to be wound around the winding drum 2.

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 l to be wound in a spiral shape.
The main and sub slats 4.5 can be connected by simply inserting the side edges of the sub slat 5 into the fitting grooves 4a and 4b of the main slat 4, so the connection is not easy.
The load applied to the sub-slats 5 when the shutter curtain 1 is fully closed is also in the direction of the face plate, so there is no unreasonable load on the bent part, as in the case where the connecting part of the main and sub-slats 4.5 is bent toward the indoor side. This is a preferable structure from a structural standpoint.

Furthermore, in this embodiment, each slat 4.
Since the connecting portions of the five members are not exposed to the outside, it is not only favorable in terms of appearance, but also has the advantage of being very convenient in terms of crime prevention and rust prevention. Moreover, as shown in Figure 4 Y and Z, this product can be bent to accommodate both forward and reverse winding methods, so it can be handled in the same way as an interlocking type shutter curtain. There will be no problem.

In addition, in this case, the engagement piece 5c is fitted into the engagement hole 4C to prevent lateral displacement, so that the slats do not shift from side to side unlike in conventional interlocking joints. There is also the advantage that there is no need to attach end fittings.

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, each slat is As a means for connecting the slats 1 in a manner that prevents them from coming off, at least one of the mutually opposing side edges of each slat 1 is formed with a fitting groove portion that opens toward the adjacent slat side, and the other side edge portion is formed in the fitting groove portion. Therefore, as in the second embodiment shown in FIG. It is also possible to form open fitting grooves 6a, 7a and to fit the upper edges of the adjacent slats 6.7 into these fitting grooves 6a, 7a, and by doing so, it is possible to improve the rain protection. That's convenient. Of course, the fitting groove portion may be formed only on the sub-slat side, completely contrary to the case of the first embodiment.

Further, in each of the above-mentioned embodiments, the thickness of the shutter curtain is determined by the thickness of the fitting groove, and has the advantage that it can be made thinner, and such a request can be immediately met. If the same thickness is required, as shown in the third and fourth embodiments shown in Figs. The slat thickness may be increased by extending the length of the slat, and this has the advantage that contact between the slats that overlap when being wound onto the winding drum 2 can be avoided as much as possible.

Further, in the fourth embodiment, a different method from the above-mentioned embodiments is adopted for the retaining means. In other words, in this device, fitting grooves 4a and 4b are formed in the main slat 4, while rib-shaped fitting portions 5b are formed on both side edges of the sub-slat 5. They are connected in a manner that prevents them from coming off by being slidably fitted in the fitting grooves 4a and 4b in the lateral direction, and of course this arrangement is also acceptable.

Furthermore, patterns such as those shown in FIG. 8 (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. 8A), the slat surface has a substantially corrugated plate shape (Fig. 8B), and the slat surface has a substantially zigzag shape. (Fig. 8C), slats with roughly uneven slats (Fig. 8D), 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 (8th
(Fig. E), conversely, the main slat is connected between a plurality of sub-slats 5 (Fig. 8 F), and the convergence 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 (
In addition, various types of fixing means such as rivets or other general-purpose fixing means can be used as the means for preventing the slats from being pulled out (FIG. 8H).

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

[Operations and Effects] In summary, since the present invention is constructed as described above, the shutter curtain has main slats made of a rigid material and sub-slats made of an elastic material. By using slats, these side edges can be integrally connected to each other, eliminating the interlocking joints that were required in the past.Therefore, there is no gap between adjacent slats, making it easier to open and close the slats and prevent wind. It is possible to avoid the generation of unpleasant noise caused by the slats rubbing against each other or colliding with each other when the slats are hit, etc., and the noise can be significantly reduced, making it quieter. Furthermore, since there are no gaps between adjacent slats, it greatly contributes to improved fire prevention, smoke prevention, and sound insulation.

can do.

Moreover, the slats can be connected by simply inserting the side edges of the adjacent slats into the fitting grooves opened on the adjacent slat sides, so the connection mechanism is simple and can be connected when the shutter curtain is fully opened. Since the load acting on the joint is naturally oriented toward the face plate, there is no need to apply an unreasonable load to the bent part, unlike when the connecting part is bent toward the indoor side, making this a preferable configuration from a structural standpoint. Become.
