Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seat plate of a shutter curtain used for a building opening consisting of a circular arc-shaped wall surface.

[Problems to be solved by the prior art and the invention] The shutter curtain of conventional shutter devices has a linear seat plate, but in recent years the number of buildings with circular or even arc-shaped walls has been increasing. When a conventional standard shutter device is installed in a building, when looking up at the lintel from below with the shutter curtain rolled up, there is a gap between the building and the seat board, which is not aesthetically pleasing. Therefore, in order to solve this problem, a shutter with a shape that conforms to the arcuate wall surface is required, but if it is formed and manufactured in a shape that follows the building, it will be structurally difficult and expensive.

[Means for solving the problem] The present invention was devised in order to eliminate this problem in view of the above-mentioned circumstances. In an architectural shutter in which the shutter curtain is raised and lowered, the seat plate provided at the lower edge of the lowermost slat of the shutter curtain is formed into an arc shape that conforms to the arc-shaped wall surface. To provide a simple and inexpensive shutter that does not impair the appearance of the shutter when it is used.

[Example] Next, an example of the seat plate structure of a shutter curtain according to the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a shutter curtain, which is made up of a number of continuous slats, and its ends are fitted into guide rails 4, 4, which are vertically installed on the left and right sides of the entrance/exit opening 3 of the building 2, which consists of an arcuate wall surface. It is wound up on a winding shaft 6 in a case 5 attached to the upper part of the case 5 via a bracket so that it can be opened and closed. At the lower edge of the lower end slat 1a of the shutter curtain 1, an arcuate seat plate 1b is provided to match the shape of the building, for example, if the building has an arcuate wall surface.

The lintel 7 at the bottom of the case 5 is formed in the same arc shape as the seat plate 1b, so that when the shutter curtain 1 is raised and opened and placed in the case 5, the seat plate 1b is attached to the lintel 7. They overlap and cover each other.

The seat plate 1b is, as shown in FIG.
One end side is extended, and this extended part is folded back to form an arc shape, and the folded end edge is bent at a right angle.
The lowermost slat 1a is applied to this bent piece 1c and welded, or the seat plate 1b is formed by forming a plate into an arc shape as shown in FIG. 6, and the lowermost slat 1a is placed on this seat plate 1b. The flat portion provided on the lower edge may be integrally provided in an appropriate state such as by welding.

[Operations and Effects] As is clear from the above-mentioned configuration, the present invention provides a seat plate 1b shaped into an arc shape, for example, which is adapted to the shape of an arc-shaped wall building, at the lower edge of the lowermost slat 1a of the shutter curtain 1. Accordingly, when the shutter curtain 1 is wound around the winding shaft 6 in the case 5 and the opening 3 is opened, the seat plate 1b is formed into an arc shape and overlaps the lintel 7 provided at the bottom of the case. This is designed to cover the gap between the stored shutter curtain 1 and the building, and even when viewed from the opening 3, the gap is closed, so the exterior beauty is not impaired, and it is also desirable from a design perspective. shape, and conventional standard shutter curtains can be used.

The present invention is applied to an architectural shutter in which the shutter curtain is raised and lowered up and down along guide rails erected on the left and right sides of an opening provided in an arcuate wall surface as described above. The seat plate structure of the shutter curtain is formed into an arc shape that conforms to the arc-shaped wall surface, and the shutter curtain has an opening provided in the arc-shaped wall surface. Since a linear shutter curtain is used, it can be rolled up smoothly as before, and there are no structural difficulties. In addition, since the seat plate has the same arc shape as the arc-shaped wall surface and is provided at the lower edge of the lower end slat, when the shutter curtain is rolled up, when viewed from below, it looks like it matches the shape of the arc-shaped wall surface, so it does not spoil the appearance. There is no. It also has the advantage of being simple and inexpensive.
