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 is working. 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 made with the object of providing a shutter curtain for buildings that can eliminate these drawbacks. What is claimed is: 1. A shutter curtain for a building that opens and closes, wherein the shutter curtain comprises a main slit formed of a rigid material and a sub-slat formed of an elastic material. On both sides, fitting grooves protruding toward the indoor side and opening on the outdoor side are formed, and fitting sides formed by projecting toward the indoor side on both sides of the sub-slat are fitted into these fitting grooves. The connecting portion is connected in a series, and the distal end edge of the fitting portion is further bent outward in an expanded shape.

And, according to the present invention, with this configuration, it is possible to prevent the seat plate and the slant from falling down while being a horizontal pulling shutter,
In addition, the interlock connection is eliminated, so that a low-noise shutter can be obtained.

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. It is configured to be vertically opened and closed by being guided by 3.

The shutter curtain 1 includes a main slat 4 formed of a rigid material such as a metal material such as steel or aluminum or a synthetic resin material used for an existing shutter curtain, 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 formed in a substantially U-shape in such a manner as to be inclined upward toward the tip by an appropriate forming method such as molding or roll forming, and both legs are further outwardly formed. The hairpin groove-shaped fitting grooves 4a and 4b are folded back toward (for convenience, the upper fitting groove is used to move the shutter curtain 1 in the vertical direction).
4a, and the lower fitting groove is numbered 4b). 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 length in the pitch A direction). Is set to B. Further, the front end edges of the fitting grooves 4a and 4b are formed with a bent portion 4d which is bent in an expanded shape.

On the other hand, the sub-slat 5 is formed in a substantially U-shape in such a manner as to be inclined upward toward the tip of the arrowhead, and its legs 5a and 5b (for convenience, the shutter curtain 1 is moved in the vertical direction) The upper leg side is 5a, the lower leg side is 5b
The engagement side 5c is stamped and formed so that the tip is on the crotch side and protrudes toward both leg side opposing sides. The engagement side 5c has a pitch
The length is set to be approximately half (B / 2) of the length of 4c.

The shutter curtain 1 pushes the lower fitting side 5b of the sub-slat 5 into the upper fitting groove 4a of the main slit 4 until the engaging side 5c engages with the engaging hole 4c. The upper curtain side 5a of the sub-slat 5 is similarly pushed into the fitting groove 4b and fitted to form a series. The shutter curtain thus formed in a series is formed. Reference numeral 1 denotes a configuration in which the sub-slat 5 is wound around the winding drum 2 by being elastically deformed and curved.

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 the opening / closing operation or when the wind is received, it is possible to reliably avoid the generation of noise due to the collision of the slats, and it is possible to provide a quiet low-noise building shutter. Further, since there is no gap between the connecting portions of the slats, there is an advantage that the fire prevention, the smoke prevention and the sound insulation are excellent.

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.

In addition, when the sub-slat 5 is curved, the sub-slat 5 is curved with the fitting sides 5a and 5b on both sides fitted and supported by the main-slot 4 side. The leading edge of each fitting groove 4a, 4b has an expanded bent portion 4d.
The sub-slat 5 is gently curved so as to be guided and supported by the expanding bent portion 4d so as to draw a large arc from the fitting sides 5a and 5b. Accordingly, the elastic deformation of the sub-slat 5 can be reasonably performed, and the problem of bending beyond the elastic limit can be reliably avoided.

Further, in this case, since the connecting end portions of the respective slats 4 and 5 are not exposed to the outside, it is preferable not only in appearance but also in security and rust prevention. In addition, since the connecting side to be bent is inclined upward toward the tip, there is an advantage that the rain is improved. In addition, as shown in FIGS. 4 and 5, since bending can be performed in both forward and reverse winding systems, the same handling as in the case of an interlocking-type shutter curtain can be achieved. You can do it,
There is no problem.

Also, in this device, since the engagement piece 5c is engaged with the engagement hole 4c and the displacement in the left and right direction is regulated, the sludges are prevented from shifting left and right as in the conventional interlock connection. There is also an advantage that there is no need to attach end fittings.

The present invention is, of course, not limited to the embodiment described above, and the fitting groove and the fitting side project in the vertical direction as in the second embodiment shown in FIG. That is fine. Furthermore, the retaining means at the fitting part is
The engaging piece is not limited to the one in which the engaging piece is fitted into the engaging hole, and a general stopping means such as a rivet may be employed.

Incidentally, in each of the above embodiments, the width of each of the main and sub-slats (the width in the guide rail direction, not in the direction between the opposing guide rails) can be arbitrarily set as necessary. It is needless to say that may be wider than the main slat.

Further, the present invention uses a rigid main slide and an elastic sub-slat, and folds both side edges of each of these slats toward one side of the curtain surface, and fits these bent sides together. Any structure may be used as long as they are connected so that adjacent slats are connected. Therefore, a pattern diagram shown in FIG. 7 (where a solid line represents a main slat and a dashed line represents a subslat) can be used. It may be something. That is, the main slat 4 has a substantially Σ shape (FIG. 7A), the main slat 4 has a substantially semicircular shape (FIG. 7B), and the main slat 4 has a substantially wavy slat surface. One having a plate shape (Fig. 7C), one having a substantially zigzag-shaped slat surface (Fig. 7D), one having a substantially uneven slat surface of the main slat 4. (FIG. 7E), etc., those having various patterns applied to the slat surface, those having these patterns applied to the sub-slat 5 side, and those combining these various main and sub-slats, or A plurality of main slats 4 (three in the drawing) are connected to each other with a sub-slat 5 interposed therebetween (FIG. 7F). With the connection (Fig. 7G), the sub-slot 5 is connected to the main Remote that longer (Fig. 7 H) or the like, and it can adopt various things.

Further, as shown in the pattern diagram of FIG. 8, 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. , And the guide rail 3 can be applied to a horizontal storage rail 8 via a curved rail (FIG. 8B).

[Effects] In summary, since the present invention is configured as described above, the shutter curtain is made of a material having elasticity and each side of the main slat formed of a rigid material. Each side of the formed sub-slats is alternately and integrally connected, eliminating the need for the interlocking joints required in the past.Therefore, there is no gap between the adjacent main and sub-slats, and opening and closing There is no unpleasant noise caused by rubbing or abutment between the slats when operating or receiving wind, etc.
It can be quiet.

Moreover, since the connection of the main and sub-slats is performed by pushing the fitting side of the sub-slat side into the fitting portion formed on the main slide side, the connection end is not exposed to the outside. Of course, it is preferable in terms of appearance, but it has the advantage that it is very convenient for crime prevention and rust prevention. The same handling as in the case of the lock-type shutter curtain can be performed, and there is no problem.

In addition, when the sub-slat is curved, the sub-slat is curved with the fitting sides on both sides fitted and supported on the main-slat side. Since it is in the expanded shape, the sub-slats are guided and supported by the expanded portion, and gently curve so as to draw a large arc from the fitting side. As a result, the elastic deformation of the sub-slat can be reasonably performed, and the problem of bending beyond the elastic limit can be reliably avoided.
