Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foldable paper blind.

A paper blind has already been proposed in which pleat-like folds are formed on a screen made of paper at regular intervals in the lateral direction, thereby making it possible to fold the screen vertically. However, in conventional blinds of this type, the paper screen has been pleated so as to be perpendicular to the paper feeding direction of the paper roll. Therefore, the horizontal length of the blind, that is, the width, is necessarily limited by the width of the paper that makes up the screen. The only way to obtain the desired width is to seam the sheets of paper together.In this case, the screen of the blind has a seam that runs perpendicular to the folds, that is, in the vertical direction, and when applied to a wide window frame. In such a case, the seams would appear and spoil the aesthetic appearance of the blind.

Therefore, the present invention has been devised to eliminate the above-mentioned defects of the prior art, and will be described below with reference to the drawings.

In the figure, 1 shows the entire paper blind, 2 and 8 are frames attached to both the upper and lower ends of the blind 1, 4 is a pitch control belt for adjusting the opening of the blind 1 uniformly, and 5 is an operating string. .

The screen 6 of this blind 1 consists of a plurality of screen pieces 6a that are continuously joined in the vertical direction, and each screen piece 6a is made of Japanese paper, paperboard, etc.
It is made of synthetic paper or other paper having appropriate rigidity, and its folds 7 are provided parallel to the paper feeding direction of the paper winding row/'L'.

That is, the folds 7 of each screen piece 6a have an appropriate width of l.
The blind 1 is provided parallel to the paper feeding direction of the paper roll μ of the same paper, therefore, the lateral length of the blind 1, that is, the width is independent of the restriction on the paper width of the paper. Furthermore, it has a required length m that is longer than the paper width in a seamless state.

On the other hand, since the vertical direction of the blind 1 is formed by vertically joining a plurality of screen pieces 6a, its length, that is, the length, is influenced by the total length 40 of the vertical direction of each screen piece 6a. , and has the required length n determined thereby.

The vertical seaming of each screen piece 6a is as follows:
As shown in an enlarged view in FIG. 2(a), the folded pieces 8a and 9a located at the lowermost and uppermost ends of each screen piece 6a and 6a are overlapped. If necessary, apply adhesive or the like to the polymerized surface to make the seam firm.

However, various forms can be considered for such vertical seaming. For example, as shown in FIG. Fold pieces 8a and 8'l) and 9b and 9a
When applying adhesive to make the joints vertical and rigid, as in (g) above, in this example, in order to make the joint part open well, apply adhesive to the entire overlapped surface. Rather than applying adhesive, it is applied only to the top and bottom overlap areas, conveniently indicated by points 10 and 11 in the figure.

Moreover, in the same figure (C), in the form shown in the above (a),
An example is shown in which a plate-like piece 12 of a metal material such as aluminum, plastic, wood, or other material is interposed between the overlapping surfaces and joined together.

In addition, the same figure (α) shows a cross section H made of plastic etc.
Using the clamping force of the shaped joint member 18, the folded pleats 8 at the bottom and top ends of each screen piece 6a, 6a are folded.
An example in which each of a and 9a are joined is shown. Adhesive may also be used if necessary.

Furthermore, the same figures (e) and (f) are modified examples of the above-mentioned ((1-), and both have a joint member 14 having a U-shaped cross section.
This shows an example of splicing using the clamping force of . The difference between the examples in (e) and (f) is that each screen piece 6a is in the joint portion.

It is in the bending direction of fold 7 of fold 6a.

In the above embodiments, an example was shown in which the blind was formed from a plurality of screen pieces assembled together, but if the length of the entire blind was shorter than the length of the paper forming the screen pieces. is naturally formed by only one screen piece.

As described in detail above, in the paper blind of the present invention, the screen piece 6a is formed of paper with folded p folds parallel to the paper feeding direction of the paper roll, and one of the screen pieces 6a is
Since the screen 6 is formed by a number of screen pieces a or a plurality of screen pieces 6a that are successively joined as required in the vertical direction, the length of the blind in the vertical direction,
That is, not only the length but also the lateral length, that is, the width, can be any desired length without being restricted by the paper width. Therefore, even by using existing machinery and equipment as is, it is possible to provide a wide paper plind with no horizontal seams, a desired width, and a beautiful appearance.

Of course, there will be seams in the vertical direction of the blind, but since the seams are horizontal, there is a certain sense of rhythm and stability, which makes it look even more beautiful.
However, the desired result is that the blind itself has an appropriate stiffness at the seam and its resistance to lateral pressure is improved.

Furthermore, by preparing various types of null pieces having different lengths in the vertical direction, it is possible to obtain a finely detailed blind with a desired length by combining them in any desired manner.
