Description

  The present invention relates to a pleated curtain substrate in which a plurality of folds are formed as a folding curtain.

The conventional pleated curtain substrate has a monotonous appearance with no change because only creases are formed at predetermined intervals.
A pleated curtain using such a pleated curtain substrate gives an impression as a building material that is mainly used for physical properties such as light-shielding properties and eye-shielding properties rather than indoor decorations. Demand was limited.

A pleated curtain substrate is known in which crease intervals are random in order to enhance the decorativeness of the pleated curtain substrate (for example, Patent Document 1).
However, in the pleated curtain base with a random crease interval, according to this, a difference in height is generated in the crease due to the random interval between the creases, and the appearance is changed compared to conventional products, It is difficult to say that the degree of change in appearance due to the difference in height is monotonous and can provide a special three-dimensional effect.

Japanese Patent Laid-Open No. 10-77773

  Accordingly, an object of the present invention is to provide a novel pleated curtain having a high added value as an indoor ornament by generating a decorative pattern three-dimensionally on a pleated curtain base.

  In the pleated curtain base according to the present invention, (a) a plurality of main creases 13 are formed in parallel at a predetermined interval, and (b) adjacent main creases 13 and 13 are folded in opposite directions. 11 and a valley crease 12. (C) A crossing 15 is made to cross the main crease 13; (D) A main crease 13 to which the cut 15 is crossed is bordered by the cut 15 The first feature is that it is divided into a mountain fold line 13 (18) and a valley fold line 18 (13) whose bending directions are reversed.

  In addition to the first feature, the second feature of the pleated curtain base according to the present invention continues from the end portion 16 of the cut 15 in the length direction of the main fold line (18) inverted from the cut 15 as a boundary. It is in the point where the minor crease 17 is attached.

  A third feature of the pleated curtain base according to the present invention is that, in addition to any of the first and second features, the pleated curtain base 10 is made of a fiber, and the folds (13, 17, 18) The fiber is in a form that is different from the fiber in the portion 14 other than the fold.

  According to the present invention, in the pleated curtain substrate, the subfolds 17 having irregular intervals are attached to the main folds 13 that are regularly provided at predetermined intervals, so that a three-dimensional structure can be obtained even in a certain amount of calmness. It has a beautiful aesthetic.

  Further, in the pleated curtain base, when a part of the main fold 13 is protruded or recessed into the sub fold 17 by the cut line 15, a gap 19 is generated between the main fold 13 and the sub fold 17, and the gap 19 The light like the sun leaks through, and the radiant pattern appears and you can enjoy the elegant lighting.

  Further, the main fold line 13, the sub-fold line 17, or the cut line 15 is formed by irradiating the pleated curtain substrate 10 with a laser beam, and the fibers in the fold lines (13, 17, and 18) are formed in the fibers other than the fold line 14. The pleated curtain substrate can be changed by a high degree of freedom without complicated work of partially cutting and pleating the pleated curtain substrate with a pleating machine as in the prior art. It can be produced efficiently.

  As described above, the pleated curtain base of the present invention has both functionality and decoration, and can be obtained efficiently. Therefore, the present invention is very advantageous in expanding its application.

FIG. 1 is a perspective view of an elevating / closing pleated curtain using a pleated curtain substrate 10 according to the present invention, and a part of the pleated curtain pleat curtain is shown enlarged in a circle.
The upper end of the pleated curtain base 10 is fixed to the head box 50, and the bottom rail 51 is attached to the lower end thereof.
Plural main folds 13 (11, 12, 11, 12, 11, 12,...) Are repeatedly set on the pleated curtain base body 10 at predetermined intervals in the vertical direction. It has become.
In the vicinity of an intermediate portion between adjacent main folds 11 (13) and main folds 12 (13) at both left and right ends of the pleated curtain base 10, a lifting cord insertion hole 53 through which the lifting cord 52 is inserted is formed.
The lifting cord insertion holes 53 at the left and right ends of the pleated curtain base 10 are inserted with the lifting cords 52 that are suspended from the left and right ends of the head box 50 so as to be lifted.
The lifting / lowering cord 52 is folded back to the other end facing the left and right by the bottom rail 51, and is again inserted into the left and right ends of the pleated curtain base 10, and the terminal is fixed to the head rail 50.
The lifting / lowering cord 52 is pulled into the head box 50, guided in the longitudinal direction of the head box 50, pulled out from one end of the head box 50 through a cord stopper 55 provided in the head box 50, and the operation unit 54. It is connected to.

The opening / closing operation of the pleat curtain is performed by first pulling the operating portion 54 and pulling the lifting / lowering cord 52 hanging from the head box 50 into the head box 50.
The bottom rail 51 rises as the elevating cords 52a and 52b hanging from the head box 50 become shorter, are folded up sequentially from the lower side of the pleated curtain base 10, and are successively adjacent main folds 11 (13 ) And the main fold line 12 (13) is decreased, and as the opening angle θ is decreased, the vertically and vertically adjacent lifting / lowering cord insertion holes 53 and 53 are aligned on the vertical line, and are lifted / lowered. The cord 52 can be pulled up smoothly.
In order to stop the bottom rail 51 in the ascending process at a desired height, the stopper 55 is fastened and the elevating cord 52 is gripped.
At that time, in the portion where the upper opening angle θ is large, the lifting / lowering cord 52 is in pressure contact with the insertion hole 53 and is subjected to strong frictional resistance from the insertion hole 53, so the main fold line 11 (13) and the main fold line 12. The space between (13) is maintained in a closed state, and the space between the lower main fold line 11 (13) and the main fold line 12 (13) is maintained in a folded open state.
Thus, the pleated curtain base 10 is left open to an arbitrary height.
If only one lifting / lowering cord 53a (53b) among the left / right lifting / lowering cords (53a, 53b) is operated, only one side of the pleated curtain base 10 is opened / closed.

The pleated curtain base 10 has (a) a plurality of main folds 13 formed in parallel at a predetermined interval, and (b) the bending directions of adjacent main folds 13 and 13 are opposite to each other. The main crease 11 constitutes a main mountain crease 11 projecting relative to the other main crease, and the other main crease constitutes a main valley crease 12 recessed relative to one main crease, (c The main mountain crease 11 and the main valley crease 12 continue alternately. (D) A flat plate portion 14a between one main fold line 13a adjacent to an arbitrary main fold line 13 and an arbitrary main fold line 13, and the other main fold line 13b adjacent to the arbitrary main fold line 13 and an arbitrary main fold line 13; Two adjacent flat plate portions 14a and 14b with a flat plate portion 14b between them are provided with a cut 15 that continues across the arbitrary main fold 13, and (e) the two adjacent flat plate portions 14a and 14b 14b is provided with sub-folds 17 and 17 extending in the length direction of the main fold line 13 through the end portions 16 and 16 of the cut line 15; and (f) the cut line 15 of the arbitrary main fold line 13 is formed. One side as a boundary is a reverse fold 18 that is folded back in the opposite direction to the other side, and (g)
The bending directions of the subfolds 17 and the reverse folds 18 are opposite to each other, and the bending directions of the arbitrary folds 13 and the subfolds 17 are the same.
The distances from the end portions 16 and 16 of the cuts 15 and 15 through which the subfolds 17 of the two adjacent flat plate portions 14a and 14b pass to the reverse fold line 18 (arbitrary main fold line 13) may be equal.

In the portion of the pleated curtain substrate shown in FIG. 1 surrounded by a circle A, (h) two flat plate portions 14a and 14b adjacent to each other at an arbitrary main fold line 13 are crossed to the arbitrary main fold line 13. A plurality of continuous cuts are made, and (i) subfolds 17 are continuous between two adjacent cuts 15a and 15b in the multiple cuts.
The secondary fold 17 is parallel to the main fold 13, and when the main fold forms the main valley fold 12, a mountain fold projecting between the main mountain fold 11 and the main mountain fold 11 is formed. Thus, when the main fold line 13 forms a main mountain fold line, a valley crease having a recessed ridge line is formed.

In the portion of the pleated curtain substrate shown in FIG. 1 surrounded by a circle B, the subfold line 17 continues to the edge 22 of the pleated curtain substrate.
The secondary fold 17 is parallel to the main fold 13, and when the main fold forms the main valley fold 12, a mountain fold projecting between the main mountain fold 11 and the main mountain fold 11 is formed. Thus, when the main fold line 13 forms a main mountain fold line, a valley crease having a recessed ridge line is formed.

  In the portion of the pleated curtain substrate shown in FIG. 1 surrounded by a circle C, when the sub-fold 17 intersects the main fold 13 and the main fold forms the main valley fold 12, the main mountain fold 11 and the main mountain A triangular pyramid mountain crease projecting between the valleys between the crease 11 and the main crease 13 is formed. When the main crease 13 forms a main crease, a triangular pyramid valley crease having a recessed ridge line is formed. .

  As shown by these portions A, B, and C, the number of cuts 15 intersecting an arbitrary main fold line 13 may be an odd number (including one) or an even number, and the length of the cut 15 or an arbitrary number. By changing the angle α formed by the main fold line 13 and the sub-fold line 17, the unevenness 20 and 21 having different shapes and heights can give a three-dimensional feeling to the pleated curtain base 10 to enhance the decorativeness.

  The cut line 15 is not necessarily required to be a straight line orthogonal to the main fold line 13, and may be a curved line like a cut line 15 surrounded by a circle D of the pleated curtain base shown in FIG. 1. . In this case, the distances from the end portions 16 and 16 of the cuts 15 and 15 through which the sub-folds 17 of the two adjacent flat plate portions 14a and 14b pass are made equal to the reverse fold line 18 (arbitrary main fold line 13).

When forming the reverse fold line 18 in which the bending direction of the main fold line 13 is reversed in the cut line 15, the cut line 15 is opened to form a gap 19 and light leakage occurs.
Therefore, the decorativeness of the pleated curtain substrate 10 can be further enhanced by interspersing the cuts 15 in a pattern and changing the shapes of the recesses 20 and the projections 21 formed in the cuts 15.

A constant opening angle θ is maintained between the adjacent flat plate portions 14 a and 14 b of the pleated curtain substrate 10, and the opening angle θ is also maintained between the sub-fold 17 or the reverse fold and the flat plate portion 14.
Therefore, in the process of opening and closing the pleated curtain substrate 10, the irregularities 20 and 21 formed at the cut 15 are not lost.

For the pleated curtain substrate, paper, plastic multilayer film, synthetic leather, artificial leather, nonwoven fabric, woven fabric, knitted fabric and the like are used.
When using artificial leather, non-woven fabric, woven fabric, or knitted fabric, the pleated curtain substrate may be composed of thermoplastic synthetic fibers such as nylon, vinylon, polypropylene fiber, polyester fiber, and acrylic fiber.

The cut 15 may be formed using a laser beam cutter such as a CO ₂ laser irradiation device (G-100 manufactured by Coherent) after the main fold 13 is formed.
However, when the laser beam cutter is used in such a manner, the laser beam is irradiated on the portion to be the fold (13, 17, 18), and at the same time, the laser beam is irradiated to make the cut 15. You can also
Of course, the main fold line 13 can be attached by folding the pleated curtain substrate at a predetermined interval and heating and setting.

  When a laser beam cutter is applied to the pleated curtain substrate 10 that becomes a thermoplastic synthetic fiber, the fibers in the main fold line 13, the sub fold line 17, the reverse fold line 18, and the cut line 15 are transformed into a different form from the fiber in the flat plate part 14, The folds (13, 17, 18) can be attached without folding, and the fiber 15 is convenient because the fibers are fused and prevented from breaking.

  As in the portion surrounded by the circle D of the pleated curtain base shown in FIG. 1, the subfolds 17 and the reverse folds 18 are provided with cuts that intersect like the optional main folds 13, and the subfolds 17 and the reverse folds are reversed. Further unevenness 23 can be added to the recess 20 or the protrusion 21 generated along the fold line 18.

As shown in FIG. 1, the pleated curtain base 10 is used with the main fold line 13 oriented in the horizontal direction, the main fold line 13 used in the vertical direction, and also used in the oblique direction. You can also
Further, the pleated curtain substrate 10 can be used by being hung at the window, or by being incorporated between the glass plates of a double-glazed glass window in which the glass plates are double incorporated.
