[Problems to be solved by the invention]

However, the above-mentioned conventional belt-shaped sheet shutter has the following problems. B) Due to the form of the fixture, it was decided to attach the shaft and the belt-shaped sheet at the same time. That is, when attaching or replacing the belt-shaped sheet, the shaft holding portion is sandwiched by the shaft, and the worker holds the fixing tool with one hand while holding the belt-shaped sheet with the other one hand and tightening with bolts and nuts. There was a problem that it was difficult to carry out the hanging work, it took time and labor, and the workability was extremely poor. (B) Also, in the fixture with the strip-shaped sheet attached, the shaft holding part rotates while slidingly contacting the shaft when the strip-shaped sheets are pushed and separated, so that the resistance is large and the gluing part of the strip-shaped sheet is severely damaged. There was a problem that durability becomes poor.

This invention has been made in view of the above problems, and it is extremely easy and efficient to hang up a seat fixture to which a belt-shaped sheet is attached, and further, durability is maintained even if damage to the belt-shaped sheet is reduced. It is a technical subject to provide a strip-shaped sheet shutter.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a pair of seat mounting portions having substantially the same width as the strip-shaped sheet to be mounted on the upper end portion of the strip-shaped sheet, and protruding outward from the central portion of the non-seat mounting surface of the seat mounting portion. A seat attachment consisting of the balanced protrusion,
A support body that is attached to the upper part of the entrance and exit of a building or the like and is arranged and supported by inserting the seat fixture therein, and an opening for inserting a belt-shaped sheet across the width direction of the entrance and exit is formed on the lower surface of the support. A belt-shaped sheet shutter is provided in which both sides of the lower surface portion forming the opening are formed with support portions for supporting the balance protrusion from below and allowing the seat fixture to swing.

[Action]

According to this invention, a plurality of belt-shaped sheets prepared can be preliminarily attached to the seat attachment portion of the seat attachment, respectively.
By inserting the strip-shaped sheet into the opening and the balance protrusion on the support, the support attached to the upper part of the entrance and exit can support the sheet attachment to which the strip-shaped sheet is attached. By sequentially inserting the sheet fixtures into the support and suspending them while alternately arranging the overlaps of the ends of the adjacent sheet attachment parts, the sheet attachments can be performed by pressing the belt-like sheets when moving in and out of the belt-like sheet shutter. While the tool is supported by the support portion of the support body, the tool freely swings to allow passage.
