Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a shutter constructed by foldably connecting a plurality of panel bodies in which two outer skins are filled with a hard foamed synthetic resin.

[Background Art] Shutters in which multiple panel bodies are folded and freely connected have been known, but conventional shutters have panel bodies made of a single piece of metal, which suffers from poor airtightness and heat insulation properties. It was hot. Particularly in recent years, shutters used in garages, factory openings, etc. are often required to have insulation properties, and conventional shutters have not been able to adequately meet this requirement. Therefore, the inventor thought of forming a panel body by filling the space between two outer skins with foamed synthetic resin, and connecting multiple panels with hinges to form a shutter. To connect the panel bodies with each other with a hinge, the hinge plate portion of the hinge is fixed to one side of the outer skin using a fixing tool, and the panel bodies are connected with the hinge. However, the sandwich structure of the panel body filled with foamed synthetic resin increases its weight, and when used as a shutter, it is difficult to sufficiently connect the panel bodies with each other using hinges. When large-sized shutters are used as shutters to open and close large openings in buildings, there is a problem in that the weight increases and the connection between the panel bodies using hinges is unstable.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to improve the insulation of the shutter by increasing the insulation of the panel body. Furthermore, even though the panel bodies are made with a sanderch structure to improve the insulation of the shutter, the hinges allow the panel bodies to be firmly connected to each other, and the panel bodies can also be reinforced, resulting in a strong shutter. The aim is to provide the structure of the shutter that is possible.

[Disclosure of the invention] The structure of the shutter of the invention is such that a plurality of panel bodies 4 filled with a hard foamed synthetic resin 3 between outer skins 1 and 2 of two metal plates can be folded vertically using hinges 8. A reinforcing strip 1 is attached near the vertical end of the back surface of the outer skin 1 on one side of the panel body 4.
2 along the entire length in the lateral direction, the hinge plate part 10 of the hinge 8 is brought into contact with the surface of the outer skin 1, and the fixing tool 11 inserted from the hinge plate part 10 is fixed to the strip plate 12 through the outer skin 1. By adopting such a configuration, the above-mentioned object of the present invention is achieved. That is, in the present invention, since the panel body 4 is made of a material in which the hard foamed synthetic resin 3 is filled between the two outer skins 1 and 2, the heat insulation properties of the shutter 9 can be improved.
In addition, since a reinforcing band plate 12 is provided near the vertical end of the back surface of the outer skin 1 on one side of the panel body 4, the panel body 4 can be reinforced by the band plate 12, and the hinge plate of the hinge 8 can be reinforced by the band plate 12. Since the part 10 was applied to the surface of the outer skin 1 and the fixing tool 11 inserted from the hinge plate part 10 was fixed to the band plate 12 via the outer skin 1,
Although it has a sandwich structure with a rigid foamed synthetic resin 3 filled inside to provide heat insulation, the hinge 8 is fixed to the strip 12 through the outer skin 1, and the hinge 8 makes the panel have a sandwich structure. The elements 4 are connected to each other, and the position of the reinforcing band plate 12 can be fixed by foaming and curing the hard foaming synthetic resin 3, and there is no need to take any measures to fix the reinforcing plate 12. The reinforcing plate extends over the entire horizontal length of the panel body 4, allowing the installation position of the hinge 8 to be set at any horizontal location, and the reinforcing plate extends along the entire horizontal length of the back surface of the outer skin 1. 12 is lined with lining, it is possible to avoid the reinforcing band plate 12 from lifting up on the outer skin 1 and causing a shadow of the band plate 12 to appear. It has become possible to avoid problems associated with attaching hinges 8 in a shutter made of a folded shutter using a panel body 4 in the form of a filled sanderch.

The present invention will be explained in detail below with reference to Examples. The facing outer skins 1 and 2 are both metal plates, and the outer skins 1 and 2 are metal plates.
A panel body 4 is constructed by integrally filling the space with a hard foamed synthetic resin 3. A shutter 9 is constructed by vertically connecting a plurality of panel bodies 4 with hinges 8. A metal band plate 12 is provided along the entire length of the outer skin 1 in the lateral direction on the back side near the ends in the vertical direction. In order to connect the panel bodies 4 with the hinge 8, the fixing tool 11 inserted from the hinge plate part 10 is fixed to the strip plate 12 through the outer cover 1 while the hinge plate part 10 is in contact with the outer skin 1. be. By doing so, the hinge plate portion 10 is fixed to the band plate 12 via the outer skin 1, and strong fixation is possible. In the embodiment shown in FIG. 1, a fitting protrusion 5 is provided protruding from one of the opposing end surfaces of the panel elements 4 that are vertically adjacent to each other. A fitting recess 6 is provided. Here, at least one of the fitting protrusion 5 and the fitting recess 6 is provided with an elastic airtight material 7,
In the embodiment shown in the drawings, an airtight material 7 is provided in the fitting recess 6. In the embodiment shown in FIG.
One side of an airtight material 7 such as a gasket is fitted into the panel 8, and the abutting portion 26 of the other panel element 4 comes into elastic contact with the fin piece 27 of the airtight material 7 to maintain airtightness at the connection between the panel elements 4. It's becoming like that. In any of the above embodiments, rollers 13 are attached to both left and right ends of the panel body 4. In the embodiment shown in FIG. 6, a roller support portion 10a is provided on one hinge plate portion 10 of the hinge 8 located at the end in the lateral direction, and a roller 13 is rotatably supported on this roller support portion 10a. . Vertical rails 14 on both sides of the building opening
A horizontal rail 15 is connected from the upper end of the vertical rail 14 under the ceiling on the indoor side. In other words, the vertical rail 14 and the horizontal rail 15 constitute a substantially inverted L-shaped rail. The shutter 9 has each roller 13 fitted into the left and right rails so that it can run freely.When the shutter 9 is placed on the vertical rail 14, the opening of the building is closed, and when the shutter 9 is moved and placed on the horizontal rail 15, the opening of the building is closed. The openings in the building are now open. The shutter 9 is opened and closed by an opening and closing means 16. Figure 3 shows the opening/closing means 1.
An example of 6 is shown. In this example,
The lower end of a wire 18 wound around a pulley 17 is connected to the lowermost panel body 4, and the pulley 17 is rotated by a motor 21 to move the shutter 9 along the rail. In FIG. 3, reference numeral 19 denotes a coil spring wound around the shaft 20 of the pulley 17.
Reference numeral 9 applies a spring force to the shaft 20 in the direction of pulling up and opening the shutter 9;
It serves to reduce the force required to pull up the shutter 9 due to the rotation of the motor 21. In this embodiment, the opening/closing means 16 is composed of a pulley 17, a wire 18, a coil spring 19, a shaft 20, a motor 21, and the like. In FIG. 4, a rail body 22 is provided approximately parallel to the horizontal rail 15, and a traveling body 22 is mounted on the rail body 22 and is driven by a motor 24.
3, the traveling body 23 and the upper end of the shutter 9 are rotatably connected by a connecting body 29, and the shutter 9 is opened and closed as the traveling body 23 travels. Also in this embodiment, the coil spring 25 wound around the shaft 24 serves to reduce the pulling force when the shutter 9 is pulled up. When the shutter 9 is moved from the horizontal rail 15 to the vertical rail 14 to close the opening in the building, the fitting protrusion 5 and the fitting recess 6 fit together as shown in FIG. The airtight material 7 is compressed to ensure heat insulation and airtightness of the connection portion between the panel bodies 4. In the embodiment shown in FIG. 2, the contact portion 26 comes into elastic contact with the airtight material 7 to maintain heat insulation and airtightness. On the other hand, when opening an opening in a building, the shutter 9 is pulled up and moved from the vertical rail 14 to the horizontal rail 15. In this case, when moving from the vertical rail 14 to the horizontal rail 15 and from the horizontal rail 15 to the vertical rail 14, the panel bodies 4 are folded together at the hinges 8 and moved.

[Effects of the invention] As described above, in the present invention, a plurality of panel bodies filled with hard foamed synthetic resin between two outer skins are connected in a vertically foldable manner.
This can improve the insulation of the shutter, and since a reinforcing strip is placed vertically on the back side of the outer skin on one side of the panel body near the end, the strip can strengthen the panel body. As well as being able to
The hinge plate part of the hinge is placed on the surface of the outer skin, and the fixing tool inserted from the hinge plate part is fixed to the strip plate through the outer skin, resulting in a sandwich structure in which the inside is filled with hard foamed synthetic resin to provide insulation. Despite this, the hinges are fixed to the strips through the outer skin, and the hinges firmly connect the panel bodies of the sandwich structure, and the panel bodies are large and heavy. The panel bodies are firmly connected to each other, allowing for smooth opening and closing of the shutter even after long periods of time.Furthermore, the reinforcing strip can be fixed in its position using hard foamed synthetic resin, and the reinforcing strip can be fixed in place. There is no need to take measures for this, and since it extends over the entire length of the panel body in the lateral direction, the installation position of the hinge can be set at any point in the lateral direction, and the The entire length of the back side is lined with a reinforcing plate in the horizontal direction, which prevents the reinforcing strip from lifting up on the outer skin and causing a shadow of the strip. It is advantageous to use a panel body in the form of a filled sanderch and avoid the problems associated with mounting hinges in shutters in a folded configuration.
