[0002]

2. Description of the Related Art As a sheet-shaped member as described above,
A banner, which is one of advertising media such as slogans such as commercial advertisement, election and traffic safety, is known. Usually, these banners are hung and installed along the wall from the roof of a building such as a department store, a supermarket, or a government office.

However, the conventional curtain has a structure in which the upper and lower ends are simply tensioned in the vertical direction so that it is stretched. There was something that came off.

Therefore, in order to prevent such a situation, in order to increase the strength as a whole, there has been proposed a method of fixing the hanging curtain by using a rigid frame such as a frame.

[0005]

However, in the method of fixing the curtain using such a rigid frame,
There was a problem that it took a lot of time to assemble and the frame was visible from the outside, and it did not look good.

Therefore, the present invention provides a hanging curtain, that is, a sheet-like member tensioning device, which can improve the installation strength without using the rigid frame as described above and has a good appearance.

[0007]

These objects are achieved by the present invention described in (1) to (5) below. (1) A sheet-like member in which at least two sides are polygonal shapes that are parallel to each other, and the two sides are two edges fixed to a wire that extends substantially over the entire length thereof, and The sheet-shaped member has a length substantially equal to the length of the edge portion and is arranged parallel to each other along a wall of a building or the like with a distance substantially equal to the distance between the two edge portions. Two long guide rail members are provided, the guide rail member has a first guide groove and a second guide groove extending along the guide rail member, and the first guide groove has:
A long tension member that fits the edge portion of the sheet-shaped member so as not to come off and that fits the guide rail member in a tension state is fitted in the second guide groove. The sheet-shaped member tensioning device is characterized in that the sheet-shaped member tensioning device is provided with a tension means for applying tension to the long tension member. (2) The sheet-shaped member tensioning device according to (1), wherein the guide rail member is configured by combining a plurality of short unit members each having a predetermined length. (3) The sheet-shaped member tensioning device according to (1) or (2), wherein the guide rail member has a plurality of the first guide grooves. (4) The sheet-shaped member tensioning device according to any one of (1) to (3), wherein the long tension member is a rod-shaped member. (5) The sheet-shaped member tensioning device according to any one of (1) to (4), wherein the tension means is a turnbuckle.

[0008]

In the sheet-shaped member tensioning device of the present invention, the sheet-shaped member is fixed to the wall of a building or the like by using a long tension member such as a tension rod or a tension wire. That is, since the rigidity (rigidity) is apparently obtained by applying tension to the long tension member, the sheet-like member can be securely fixed with a slim structure, and it is almost inconspicuous and looks good. .
