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, among the shutters for buildings of this type, for example, a horizontal direction in which a winding drum mounted on one of the right and left sides of an opening is disposed vertically There is a so-called horizontal pulling shutter that opens and closes in the left and right direction guided by the guide rail.

By the way, the shutter curtain used for such a horizontal pulling shutter is similar to the case of a general vertical pulling shutter.
It is necessary to be formed so that it can be curved because it is wound around the winding drum from a straight posture along the guide rail,
Therefore, conventionally, a shutter curtain has been formed by interlocking slats formed by bending a band-shaped plate material with each other. However, in this one,
Because there is a gap in the interlock connection and there is play, there is no problem that noise is generated when opening or closing or when the wind is received at the time of closing.Because this play exists, the shutter When trying to open and close by holding the seat plate on the front end side of the curtain, there is a problem that the seat plate and the slant fall down and become inclined, so that the opening and closing operation is significantly impaired.

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 building shutter curtain capable of eliminating these drawbacks. A shutter curtain for a building, which is guided by a horizontal guide rail and opens and closes an opening in the left-right direction, the shutter curtain has a main slat formed of a rigid material and elasticity. In addition to using a sub-slat formed of a material, a fitting groove projecting toward the indoor side and opening on the outdoor side is formed at the left and right side edges of one of the adjacent slats, and these fittings are formed. It is characterized in that fitting sides projecting toward the indoor side from the left and right side edges of the other slat are inserted into the grooves and fitted in a series.

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, and the shutter curtain 1 is a winding drum 2 built on one side (left side in the embodiment) of an opening.
And is guided by horizontal guide rails 3 provided above and below the opening to open and close in the left-right direction.

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.

That is, in this embodiment, the left and right sides of the main slat 4 are formed in a substantially U-shape toward the indoor side, and the two legs are further bent back toward the outdoor side, and the hairpin having the outdoor side opened. Groove-shaped fitting grooves 4a and 4b (for convenience, the left one is distinguished as the left fitting groove 4a and the right one is distinguished as the right fitting groove 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 vertical direction (the length in the pitch A direction). Is set to B.

On the other hand, the sub-slat 5 is formed by bending an arrow-shaped approximately U-shape, and its fitting sides 5a, 5b (for convenience, the left side is the left side fitting side 5a, and the right side is the right side fitting. On the side 5b), an engagement piece 5c is formed so that the tip is on the crotch portion side and protrudes toward both fitting side opposing sides. The engagement piece 5c is set so that the pitch is substantially half (B / 2) the length of the engagement hole 4c.

The shutter curtain 1 is fitted into the left fitting groove 4a of the main slot 4 by pushing the right fitting side 5b of the sub-slot 5 until the engaging piece 5c engages with the engaging hole 4c. The left side fitting side 5a of the sub-slat 5 is similarly pushed into the groove 4b and fitted to form a series. The shutter curtain 1 formed in a series is thus formed. The subslat 5 is elastically deformed and curved so that it can 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 performed by setting the shutter curtain 1 to the guide rail 3.
The shutter curtain 1 is connected to each other by connecting the rigid shutters together like a conventional rigid lock by connecting them in a bendable manner by a conventional interlock connection. There is no gap in the part, and as a result, it is possible to reliably avoid the generation of noise due to the collision of the slats at the time of opening and closing operation or when receiving wind, etc. It can be a 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.

Further, in this case, since the shutter curtain 1 has no play at all, there is no trouble that the slatt or the seat plate falls down unlike the conventional one having the interlock connection portion, and as a result, the opening and closing operation can be remarkably improved. Therefore, it will be possible to open and close the layer Saga. In addition, since the connecting ends of the slats 4 and 5 are not exposed to the outside, it is not only preferable in appearance but also very advantageous in security and rust prevention. Moreover, as shown in FIGS. 4 and 5, the bending can be performed in both the normal winding mode and the reverse winding mode, so that it can be handled in the same manner as in the case of the interlocking type shutter curtain. And there is no problem.

Further, in this device, since the engaging piece 5c is fitted into the engaging hole 4c and the vertical displacement is restricted, the slats do not displace vertically as in the conventional interlock connection. There is also an advantage that it is not necessary to attach end fittings.

It should be noted that the present invention is not limited to the above embodiment, and the fitting groove and the fitting side project in the vertical direction as in the second embodiment shown in FIG. It may be. Further, the retaining means at the fitting portion is not limited to one in which the engagement piece is fitted and locked in the engagement hole,
General stopper means such as rivets may be employed. Further, as in the third embodiment shown in FIG. 7, the edge of the main slat 4 is further folded back to the indoor side to form a projection.
Here, the engagement piece 5c formed on the subslat 5 may be locked.

Further, the patterns may be as shown in FIG. 8 (where the solid line represents the main slit and the broken line represents the sub-slat). In other words, the main slat 4 has a substantially semi-arc-shaped slat surface (FIG. 8A), a main slat surface having a substantially corrugated plate shape (FIG. 8B), and a substantially zigzag slat surface. , The surface of which is provided with various patterns, such as those having a rough surface (FIG. 8C) and those having a substantially uneven slat surface (FIG. 8D). Side, and a combination of these various main and sub-slats, and further, a sub-slat 5 interposed between a plurality of (three in the drawing) connected mains 4 FIG. 8E), on the other hand, the main slats are connected between a plurality of sub slats 5 (FIG. 8F), and the width of each of the main and sub slats (in the direction between opposing guide rails). The width in the direction of the guide rail). Shall apply as it can be set to those toward the sub Suratsuto 5 is summer wider than the main Suratsuto 4 (FIG. 8 G) or the like, and it can adopt various things.

Further, as shown in the pattern diagram of FIG. 9, 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. 9 (A in FIG. 9) and those housed in the storage rail 8 from the guide rail 3 via the curved rail (FIG. 9B).

[Effects] In summary, since the present invention is configured as described above, the shutter curtain is composed of a main slide formed of a rigid material and a sub-slat formed of an elastic material. Can be connected in a series, eliminating the need for the interlocking joints that were required in the past.Therefore, there is no gap between adjacent slats, and when opening or closing, or when receiving wind, etc. It is possible to avoid the generation of unpleasant noise caused by the rubbing or collision of the slats, and it is possible to greatly reduce the noise and make it quieter. Since there are no gaps, it can greatly contribute to the improvement of fire prevention, smoke prevention and sound insulation.

Further, in this device, since there is no play between the slats as in the case where there is an interlock coupling portion, there is no fall of the seat plate or the slat, and the smooth opening and closing operation can be performed.

In addition, the connection of each of these slats is carried out by pushing the fitting side of the other slat into the fitting groove formed in one of the adjacent slats, so that the connection end is outside. Not to be exposed to the outside, and of course it is preferable in appearance, but it also has the advantage that it is very convenient for crime prevention and rust prevention, and it also supports both normal winding and reverse winding systems Since it can be bent, it can be handled in the same manner as in the case of an interlocking-type shutter curtain, and there is no problem.
