DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter slat constituting a shutter door used for opening and closing an opening of a building.

[0002]

2. Description of the Related Art The basic structure of a shutter is that a shutter door is formed by connecting a large number of shutter slats (hereinafter sometimes simply referred to as "slats") in a freely bendable manner. The uppermost slat is fixed to a take-up shaft, and the take-up shaft is electrically or manually rotated forward and reverse to wind up and down the shutter door around the take-up shaft. From the basic configuration of this shutter, when the shutter door is wound on the winding shaft, a gap is formed between the overlapping slats. If the gap is large, the shutter door is correspondingly moved. The winding diameter when winding is increased. In order to reduce the diameter of the shutter door during winding, the width of the slats is reduced to reduce the gap between overlapping slats. Since the number of parts is increased, there is a gap newly generated by the increased connection part, and as a result, the winding diameter of the shutter door at the time of winding cannot be reduced too much. In addition to this, if the number of connecting portions of the slats constituting the shutter door increases, the cost increases, and for these reasons, the width of the slats cannot be reduced too much. As a result, the winding diameter of the shutter door at the time of storage becomes large, so that the storage case protrudes greatly outside the building, thereby damaging the appearance of the building.

[0003] On the other hand, in houses in cold regions, etc., it is required to improve the heat insulation of the building. Since the heat insulation of the window is lower than that of the wall, the heat insulation of the window is low. Improvement is required. In particular, there is a need for improved heat insulation at night when the outside air temperature decreases. For this purpose, a shutter or a curtain is used outside the window to enhance the heat insulation. However, conventional shutters have fire protection,
Since many of them are used for security purposes, their constituent members are made of steel plates, stainless steel plates, aluminum plates, etc., and their heat insulating properties are low. Further, the constituent member of the slat is the above-described metal sheet material, and the inner side surface is exposed to the indoor side, and the interior property when viewed from the indoor side is not taken into account, giving a tasteless taste. Was.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned disadvantages of the conventional shutter door, the present invention has a high heat insulating property, and when the shutter door is wound around a winding shaft, the winding diameter is reduced. An object of the present invention is to provide a shutter slat capable of reducing the size of a storage case.

[0005]

According to the present invention, a connecting member is provided at both ends in the width direction of a strip in a longitudinal direction, and a large number of sheets can be freely bent via the connecting portion. A pair of slats for shutters for forming a shutter door by connecting to a pair of slats having a connecting portion provided only at one end in the width direction, such that the connecting portions are outside each other. Then, an elastic material is stuck to at least the inner surface, and the pair of slat single plates are integrally joined.

[0006]

According to the present invention, a pair of slat veneers are arranged in the width direction, and an elastic material is attached to at least the inner surface thereof.
Since the slats are formed by integrally combining the pair of slat veneers, when the shutter door connecting the slats is wound around the winding shaft, one slat is formed.
While being bent at the center in the width direction, the inner elastic material is brought into good contact with the inner peripheral slat veneer and wound around the winding shaft. Therefore, when the number of the connecting portions of the slats is kept the same and the number of the slats is doubled, the state becomes almost the same, and when the shutter door is wound on the winding shaft, they overlap. The gap created between the slats is reduced. As a result, the winding diameter of the shutter door with respect to the winding shaft can be reduced, and the size of the storage case is reduced, so that the storage case does not protrude from the building.

[0007]

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to examples. FIGS. 1 and 2 show a shutter door D
FIG. 3 is a side view of the slat S in a connected state, and FIG. 4 is a perspective view of the slat S. As shown in FIGS. 3 and 4, the slat veneer 1 constituting the slat S is a slightly bent thin plate-shaped member, and the connecting portion 2 is provided only at one end in the width direction. Are provided in the longitudinal direction. The connecting portion 2 is provided at one end of the slat veneer 1 in the width direction, and is provided on the inner surface thereof and has a U-shaped cross section opened at one end in the width direction. Is provided with an engaging portion 2a to reduce the width of the opening. The slat S is formed by arranging a pair of slat veneers 1 side by side with a predetermined gap 3 so that the connecting portions 2 are on the outside of each other.
And a pair of slat veneers 1 are integrally joined. The inner peripheral surface 4a of the elastic member 4 is a curved surface slightly curved in the same direction as the slat veneer 1 integrally attached to the back side. Therefore, as the slat S to which the pair of slat single plates 1 are connected, the connecting portions 2 are provided at both ends in the width direction, and the slat S can be bent in the gap 3 at the center in the width direction. The slat veneer 1 is made of a metal plate such as an aluminum plate or a steel plate, or a resin plate.

The plurality of slats S described above are connected to each other along a width direction through a connecting member 5 having a U-shaped cross section to form a shutter door D. That is, the slats S to be connected are arranged in parallel, and the connecting portions 2 facing each other are connected.
When the connecting member 5 is inserted from the end of the connecting portion 2, the engaging portions 2a of the connecting portion 2 and the connecting member 5 are engaged with each other, and the slats S are bent and connected to each other. You. Of the slats S constituting the shutter door D, only the uppermost slat S 'has a structure partially different from that of the other slats S'. That is, since the slat S 'is fixed to the winding shaft 6, the widthwise end of one slat veneer 1' constituting the slat S 'is formed in a hollow shape and closed. A plurality of insertion holes 8 for fixing bolts 7 are provided in the hollow portion along the longitudinal direction. And
When the slat S ′ is fixed to the winding shaft 6 by a fixing bolt 7 and the winding shaft 6 is rotated forward or backward by electric or manual operation, the shutter door D is wound around the winding shaft 6 or wound. It is returned.

When the shutter door D, to which a number of the slats S are connected, is wound around the winding shaft 6, as shown in FIGS. 1 and 2, a gap at the center of the slat S in the width direction is provided. 3 and the inner elastic member 4 is brought into close contact with the outer peripheral surface of the winding shaft 6 or the surface of the slat veneer 1 on the inner peripheral side, and is wound around the winding shaft 6. Can be For this reason, when the number of connecting portions of the slats S is kept the same and the number of the slats themselves is doubled, the state becomes almost the same, and the shutter door D is wound around the winding shaft 6. In addition, there is almost no gap between the overlapping slats S. Therefore, the diameter of the shutter door D wound around the winding shaft 6 can be reduced, and the size of the storage case can be reduced. Further, since the elastic member 4 is attached to the inner surface of the slat S, the heat insulating property as the shutter door D increases, and the inner surface of the slat veneer 1 is not exposed to the indoor side. The interior quality you see increases.

In the above embodiment, the elastic members 4 are attached only to the inner surfaces of the pair of slat veneers 1, and the pair of slat veneers 1 are integrally connected. When an elastic material is attached to both side surfaces of the plate 1, its heat insulating property is further enhanced. Further, the shapes of the pair of slat single plates 1 are not necessarily required to be the same shape, and may be different from each other. Furthermore, a single slat veneer having no connecting portion at both ends in the width direction is disposed between two slat veneers having a connecting portion at one end in the width direction, and these three slats are provided. When a single plate is arranged in parallel, an elastic material is stuck on at least the inner surface thereof, and integrally combined to form a slat, one slat has a structure that bends at two places, and the slat is bent. Adhesion is further improved.

[0011]

According to the present invention, a shutter slat according to the present invention comprises:
A pair of slat veneers provided with a connecting portion only at one end in the width direction are arranged such that the connecting portions are on the outside of each other, and an elastic material is attached to at least an inner surface thereof, Since a pair of slat single plates are integrally connected, forming the shutter door by connecting a large number of slats produces the following effects. (1) Without increasing the number of connecting portions as the shutter door, the number of bendable portions is doubled, and the elastic material attached to the inner surface of the slat has good adhesion, so that the shutter door is wound. The winding diameter at the time of taking can be reduced. As a result,
The storage case of the shutter door can be reduced in size, so that the storage case does not protrude from the building like a conventional shutter door. (2) Since the elastic material is adhered to the inner surface of each slat constituting the shutter door, the heat insulation as the shutter door is enhanced. (3) Since the elastic material is attached to the inner surface of the pair of slat veneers constituting the slat, the inner surface of the slat veneer is not exposed, and the interior property as viewed from the indoor side is enhanced.
