Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter curtain for a building to be built on a building such as a house or a building.

[Problems to be Solved by the Prior Art and the Invention] In general, a shutter curtain for a building of this kind, for example, a curtain wound on a winding drum is opened and closed by being guided by guide rails formed on both sides of an opening. It has become differential. By the way, this shutter curtain needs to be formed to be curved because it is wound around a winding drum from a straight posture along a guide rail. Therefore, conventionally, the shutter curtains formed by bending a band-shaped plate material are used. Are interlocked to each other to form a shutter curtain that can be bent. However, in this case, since there is a play in the interlock connecting portion due to the gap, there is a problem that noise is generated when the air is blown when the door is opened or closed or when the door is closed.

Therefore, there have been attempts to eliminate the gap in the interlocking connection portion, but these methods have a problem that the structure of the interlocking connection portion becomes complicated, and are poor in reality.

Means for Solving the Problems In view of the above-mentioned circumstances, the present invention has been created with the object of providing a shutter curtain for buildings that can eliminate these drawbacks. A shutter curtain for a building that opens and closes a part, using the main curtain formed of a rigid hollow hollow and a sub-slat formed of an elastic material. When connecting in a series, these main and width slats are connected with each other by forming a fitting groove with an open side on the outdoor side on a surface facing the width slat adjacent to the main slat, and forming a sub-slat in the fitting groove. The leg sides are fitted and connected from the outdoor side.

According to the present invention, a low noise shutter can be obtained by eliminating the interlock connection while having the hollow type slat.

Example Next, an example of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a shutter curtain of a building shutter. The shutter curtain 1 is wound around a winding drum 2 built above an opening, and guide rails provided on the left and right of the opening. 3 and is configured to be differentially opened and closed.

The shutter curtain 1 includes a main slide 4 made of a rigid material such as a metal such as steel or aluminum or a synthetic resin material used for existing shutter curtains, and a spring steel or a synthetic resin. It is constructed by alternately connecting sub-slats 5 formed of an elastic material such as a material.

In other words, in this embodiment, the main slat 4 is a horror type having a parallelogram shape in a side view formed by an appropriate forming method such as die forming, roll forming or the like, that is, a hollow type, and the adjacent sub-slats are used. In the surface portions of the upper and lower side edges opposite to 5, a fitting groove portion 4a further opened on the outdoor side,
4b (for convenience, it is assumed that the shutter curtain 1 is moved in the vertical direction. The upper fitting groove is 4a, and the lower fitting groove is 4b.
Is formed), but the fitting groove portion is formed.
4a and 4b, the indoor side end (groove inner end) is substantially flush with the indoor side surface of the main slide 4, and the outdoor side end is shorter than the outdoor side surface of the main slide 4, within the thickness of the main slide 4. It is set to fit in. An engaging hole 4c is formed on the outer side of each of the fitting grooves 4a and 4b with an interval of the pitch A. The length of the engaging hole 4c in the left-right direction (the pitch A direction). Length) is set to B.

On the other hand, the sub-slat 5 is formed in a substantially U-shape in a state in which the sub-slat 5 is inclined upward toward the tip.
For a and 5b (for convenience, the shutter curtain 1 is moved in the vertical direction and numbered so that the upper leg side is 5a and the lower leg side is 5b), the tip is on the crotch side. In addition, an engagement piece 5c is formed so as to be received and protruded to the side opposite to both leg sides. The engagement piece 5c is set so that the pitch is substantially half (B / 2) the length of the engagement hole 4c.

When the lower leg side 5b of the sub-slat 5 is fitted into the upper fitting groove 4a of the main slide 4, the shutter curtain 1 is pushed in until the engaging piece 5c is engaged with the engaging hole 4c. The upper leg 5a of the sub-slat 5 is pushed into the lower fitting groove 4b in the same manner, and is fitted and locked to form a series. The auxiliary curtain 5 is elastically deformed and curved so that the shutter curtain 1 is 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 performed by setting the shutter curtain 1 to the guide rail 3.
The shutter curtain 1 is formed by moving the rigid slats together by a conventional interlock connection such that the rigid slats can be bent freely. Is not present,
As a result, at the time of opening / closing differential, when wind is received, etc., it is possible to avoid the generation of noise due to the collision of the slats, and to provide a quiet low-noise type 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.

In addition, in the case of winding on the winding drum 2, not the rigid main slide 4 but the elastic and flexible auxiliary slide 5 is curved. Similarly, it can be spirally wound without any problem.

Furthermore, since the main slat 4 is hollow, it is particularly excellent not only in heat insulation and sound insulation but also in fire prevention and smoke prevention, which is convenient. Further, in order to improve these performances, it is more preferable that the hollow portion is filled with an appropriate filler such as glass wool, rock wool, or a foamed resin material. In this case, the fitting grooves 4a and 4b fit within the thickness of the hollow type slot, so that the appearance is not impaired, and the leg sides 5a and 5b of the sub-slot 5 are connected to the length direction of the slit (shutter curtain). Instead of the width direction).
Since the assembly space is not required twice as long as the slat length, the assembly space in the factory can be small, and the legs 5a, 5b
Is small, and the assembling property is improved.

In the first embodiment, each of the slats 4,
Since the connection ends of the five members are not exposed to the outdoors, they are not only preferable in appearance but also very advantageous in crime prevention and rust prevention. Moreover, in this one, the fourth
As shown in Figures Y and Z, bending can be performed for both forward winding and reverse winding systems, so the same handling as in the case of an interlocking-type shutter curtain can be performed, which poses a problem. There is no. Further, since the connection side to be bent is inclined upward toward the tip, there is an advantage that the rain is improved.

Further, in this device, since the engagement side 5c is engaged with the engagement hole 4c and the displacement in the left and right direction is restricted, the slats do not shift left and right as in the conventional interlocking connection. There is also an advantage that there is no need to attach end fittings.

Note that the present invention is not limited to the above embodiment,
In short, it is sufficient that a rigid main slide and an elastic sub-slat are used, and at least one of these slots is constituted by a hollow type slit.
Therefore, the pattern diagram shown in FIG. 6 (where the solid line represents the main slit and the broken line represents the subslat) may be used. That is, the main slat 4 has a hollow shape with a substantially rhombus shape (FIG. 6A), the main slat 4 has a hollow shape with a substantially elliptical shape (or an oval shape) (FIG. 6B), and the main slat 4 has a hollow shape. The hollow parts are various shapes, such as a rectangular hollow type (FIG. 6C), a hollow main type 4 with continuous arcs (FIG. 6D), and these patterns are further formed. The sub-slat 5 was interposed between the sub-slot 5 side, the combination of these various main and sub-slats, and the plural (two in the drawing) connected main slats 4. (FIG. 6E), on the other hand, a main sled 4 connected between a plurality of sub-slats 5 connected together (FIG. 6E).
Various types can be adopted, such as the one shown in FIG.

Further, as shown in the pattern diagram of FIG. 7, the storage of the shutter curtain is not limited to the one wound spirally around the winding drum as in the first embodiment described above. 7 (A in FIG. 7) and those housed in a horizontal storage rail 8 from the guide rail 3 via a curved rail (FIG. 7B).

[Effects] In summary, since the present invention is configured as described above, the shutter curtain is composed of a main hollow formed in a rigid hollow shape and a sub-slot formed of an elastic material. Since it is constituted by using the slat, the interlock connecting part which is conventionally required can be eliminated. Therefore, there is no gap between adjacent slats, and it is possible to avoid generation of unpleasant noise caused by rubbing or contact between slats when opening and closing differential or when receiving wind. It is possible to significantly reduce noise and make it quieter. Further, since there is no gap between adjacent slats, it is possible to contribute to improvement of fire prevention, smoke prevention and sound insulation.

In addition, since the main slat is hollow, not only heat insulation and sound insulation but also fire and smoke prevention are particularly excellent, which is convenient.

In addition, the fitting groove can be accommodated within the thickness of the hollow type slit, so that the appearance is not impaired.In addition, the sub-slat can be inserted by inserting the leg side from inside and outside, so that the assembly space at the factory is small. And the sliding amount of the leg side is small, so that the assemblability is improved.
