Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a shutter used for opening and closing openings in buildings.

Conventional technology Conventionally, shutters used in buildings were made of iron plates,
Create long parts by bending metal plates of an appropriate width, such as stainless steel plates or aluminum plates, and use each bent part to join multiple long parts to form a door. In addition to blocking wind and rain, it was designed to be able to handle bending when rolled up for opening and closing.

Problems to be solved Shutters manufactured by bending the metal described above have uneven surfaces at the joints between the plates.
The overall surface of the shutter is not smooth. For this reason, it is difficult to draw advertisements, notices, etc. on the surface of shutters in shops, etc., and the finish is not smooth, so the advertising effect cannot be fully demonstrated. Moreover, since it has a high thermal conductivity, heat loss is large and dew condensation occurs on the surface, which is undesirable.

Solution After various studies, the present inventor developed a shutter that can be rolled up, has a smooth surface, and has good heat insulation properties by applying fiber-reinforced cement or cement calcium silicate board members. .

The present invention consists of (a) a long plate member having the same cross-sectional shape, having a recess on one side of the upper and lower sides and a convex portion corresponding to the recess on the other side; A plate member made of fiber-reinforced cement or cement calcium silicate, having a groove connecting the hollow part and the outside, and at least one hollow part having an elliptical cross section; (b) having two heads and connecting between the heads; (c) A shutter consisting of connectors connected by thin sheets, in which multiple plate members are connected by inserting the connectors into the hollow parts of the plate members.

One embodiment of the present invention will be described using FIGS. 1 and 2. 1 and 2 show cross-sectional views of the main parts of the present invention. The connections between the plate members 5, 5 are shown, and the lower connectors are omitted. The lengths of the top and bottom in the drawings may be arbitrary, and do not indicate a relationship with the length in the width direction.

The plate member 5 is made of fiber-reinforced cement or cement calcium silicate and is elongated and has the same cross section. Manufactured by extrusion molding by mixing reinforcing short fibers with a length of 2 cm or less. It is also possible to insert long fibers or cloth-like materials during extrusion.

Organic fibers, inorganic fibers, etc. are used as reinforcing fibers.

Since the plate member 5 is obtained as a long piece by extrusion molding, it can be cut into a desired length for use.

The hollow parts 1 and 2 communicate with the outside through grooves 3 and 4, respectively, which are narrower than the hollow parts.

The hollow part 1 has an elliptical shape in the vertical direction, and the head 6 of the connector 9 inserted into the hollow part can move up and down.

The hollow portion 2 may have a size that allows the head 7 of the connector 9 to be inserted therein, but the head 7 may be movable up and down like the hollow portion 1. Further, the head 7 and a portion of the thin sheet 8 may be closely fixed and integrated with the plate member 5. Furthermore, the hollow portion 1 and the hollow portion 2 may be configured in the opposite manner. In short, when winding up the shutter, the space between the plate members 5, 5 is widened, and the flexible connector 9 described later is
It is sufficient that the entire shutter is bent by bending and winding is possible.

A convex portion 10 is provided on the upper side of the plate member 5, and a concave portion corresponding to the convex portion 10 is provided on the lower side. When the shutter is lowered and the space between the plate members 5 and 5 is eliminated, they fit together, and the plate members 5 fit neatly up and down, making the shutter surface smooth as if it were made of one plate. can.

The connector 9 has two heads connected by a thin sheet, and is made of synthetic resin, aluminum, stainless steel, or steel. This connector connects the two plate members 5,5. Connector 9
Since the heads are connected by a thin sheet, no drafts can pass between the plate members.

Since the connector 9 needs to be bent in order to wind up the shutter, it is preferably made of synthetic resin; if it is made of other materials, the thickness of the thin sheet 8 connecting the heads 6 and 7 will need to be considerably thinner.

A plurality of plate members 5 cut into lengths required for the shutter are made continuous by inserting the heads 6, 7 of the connectors 9 into the hollow parts 1, 2 to form a shutter surface.

When the head 7, the thin sheet 8, and the plate member 5 are tightly integrated, they can be made continuous by simply inserting the head 6 into the hollow portion 1.

Effects In the present invention, the hollow part of the plate member has an elliptical cross section so that the head of the connector can be moved up and down, and the connector is made of a thin sheet so that it can be bent, making it possible to wind up the shutter. .

Since we have provided corresponding uneven parts on the top and bottom of the plate members, when the shutter is lowered and used, the weight of the plate members eliminates the gap between the plate members, and the uneven parts fix the relative positions of adjacent plate members. The surfaces of the plate members match, making it appear as if the shutter is made of a single plate, and there are no large irregularities on the connecting surfaces like in conventional metal shutters.

Therefore, a smooth surface is obtained as a whole of the shutter, making it suitable for use as a single canvas for paintings and advertisements to beautify the town.

Since the connector 9 connects the heads with a thin sheet, when the plate members are connected using this, drafts between the plate members are not passed, and the plate members can be used as an outer wall.

Since the material of the plate member 5 is calcium silicate, the thermal conductivity is low and heat loss can be reduced. It also prevents rust from forming.

Furthermore, the shutter of the present invention does not have large irregularities as a whole like metal shutters, and it is possible to manufacture a product with a smooth surface that is so smooth that you can only feel the irregularities when you touch it with your finger. It can be used not only for indoor purposes, but also for indoor partitions.
