Further, as another method for connecting two screens, in Patent Document 2, a connecting member is disposed between two screens, and a part of the connecting member is bonded to one screen. A method for adhering a part of the screen to the other screen is disclosed.

Japanese Utility Model Publication No. 64-2987 Japanese Patent Laid-Open No. 9-21281

  In the methods of Patent Documents 1 and 2, it is essential to previously connect the creases facing each other between the two screens by means such as welding or adhesion, but this step is complicated and leads to an increase in manufacturing cost.

  The present invention has been made in view of such circumstances, and provides a pleated screen that is easy to manufacture and has a substantially diamond-shaped cross section.

According to the present invention, the first and second screens which are suspended from the head box directly or via another member and can be folded in a zigzag shape in the vertical direction, and disposed below the first and second screens. A bottom rail, a lifting cord that is suspended from the head box to support the bottom rail and is operated from the head box side to raise and lower the bottom rail, and a plurality of annular holding portions at predetermined intervals A pitch holding cord having
The lifting / lowering cord or an integrated cord made up of a separately provided cord is inserted into the first holding portion that penetrates the first screen and the second holding portion that penetrates the second screen. Or (2) inserted into the first cord stopper provided on the first screen, the second cord stopper provided on the second screen, and the holding portion,
Thus, a pleated screen is provided in which the first screen and the second screen are integrally held in a substantially diamond shape in cross section.

  The present inventors have intensively studied to obtain a pleated screen having a rhombus cross section without performing a connecting process of two pleated screens as in Patent Documents 1 and 2, and simply performing 2 without performing the connecting process. I arranged the screens side by side. However, the state of the fold is slightly different for each screen, and even when two screens manufactured in the same process are used, the height positions of the folds of the front and rear screens do not completely match. A new problem has arisen in that the shape formed by a single screen does not have a diamond shape in cross section. In addition, there is a problem that the two screens spread back and forth (that is, a gap is left between the two screens). Therefore, in order to deal with these new problems, a configuration in which the first screen and the second screen are integrally held by the integrated cord and the pitch holding cord as described in (1) or (2) above is adopted. The heights of the folds of the front and rear screens are substantially the same, and the spread of the front and rear of the two screens is also suppressed. As a result, the cross-sectional shape formed by the two front and rear screens becomes a substantially rhombus, and the present invention is completed. I reached.

  The point of the present invention is that the first screen and the second screen are integrally held by the integrated cord and the pitch holding cord, thereby making it possible to easily manufacture a screen having a substantially rhombic cross section. In the point. According to the present invention, it has become possible to reduce the manufacturing cost of a pleated screen having a screen having a substantially rhombic cross section.

The rail 3 includes a lifting cord 5 that is suspended from the head box 1 to support the bottom rail 3 and is operated from the head box 1 side to raise and lower the bottom rail 3. .

  Each of the first and second screens 2a and 2b (hereinafter also referred to as “screen 2”) is formed by folding one piece of fabric in a zigzag shape and arranged side by side in the front-rear direction. In the present embodiment, the first and second screens 2a and 2b are not connected to each other, but may be connected, for example, at a part attached to the bottom rail 3, or may be connected at other parts. Good. Furthermore, for example, prepare a zigzag-shaped dough equivalent to about twice the product height, fold the middle part in the vertical direction, and place the dough side by side in the front-rear direction. The bottom rail may be attached. In this case, one of the fabrics divided into two by the bottom rail 3 is the first screen 2a, and the other is the second screen 2b.

  As shown in FIG. 3, a winding shaft 4 is rotatably supported in the head box 1 based on an operation of an operating device (not shown). The upper end of the lifting / lowering cord 5 is attached to the winding shaft 4 and can be wound or rewound on the winding shaft 4 by operation of the operating device. When the lifting / lowering cord 5 is wound around the winding shaft 4, the bottom rail 3 is pulled up and the screen 2 is folded upward. When the lifting / lowering cord 5 is unwound from the winding shaft 4, the bottom rail 3 is The screen 2 is lowered and stretched downward. The lifting / lowering cord 5 is disposed between the first and second screens 2a and 2b.

  The pleated screen 10 of the present embodiment includes first and second pitch holding cords 6 a and 6 b having an upper end attached to the head box 1 and a lower end attached to the bottom rail 3. The first pitch holding cord 6a has a plurality of annular first holding portions 7a at predetermined intervals, and the front surface side of the first screen 2a (that is, the front and rear cords 5 with the first screen 2a interposed therebetween) The second pitch holding cord 6b is arranged on the opposite side of the direction, and has a plurality of annular second holding portions 7b at predetermined intervals, and the outer surface side of the second screen 2b (that is, the second screen 2b). And a second pitch holding cord 6b disposed on the opposite side of the lifting cord 5 with respect to the lifting / lowering cord 5 (hereinafter, the first and second pitch holding cords are also referred to as “pitch holding cord 6”). The first and second holding portions 7a and 7b (hereinafter also referred to as “holding portion 7”) penetrate the first and second screens 2a and 2b, respectively, and the lifting / lowering cord 5 has the first and second holding portions. It is configured to be inserted through the portions 7a and 7b. Instead of providing the first and second pitch holding cords 6a and 6b, one end is attached to the head box 1 on the outer surface side of the first screen 2a and is provided in the bottom rail 3, for example (for example, FIG. A single pitch holding cord 6 that is routed to the second screen 2b side through the guide 17 having the same configuration as the guide 17 of FIG. 13 and the other end is attached to the head box 1 on the outer surface side of the second screen 2b. May be provided.

  The pitch holding cord 6 is set to a length that is substantially tensioned when the lifting / lowering cord 5 is rewound from the winding shaft 4 and the bottom rail 3 is lowered to the lower limit.

  The pitch holding cord 6 is a cord formed by knitting yarn with a knitting machine, and a yarn is knitted to form the holding portion 7 in the cord. And the thread | yarn is exposed cyclically | annularly for every fixed space | interval, and the holding | maintenance part 7 is formed. The length of the holding portion 7 is formed so that the diameter of the lifting / lowering cord 5 is added to the folding width of the screen 2.

  The holding portion 7 penetrates the screen 2 through a slit (insertion hole) 8 provided in a fold 9 that is convex toward the outer surface side of the screen 2 (that is, in a direction away from the lifting / lowering cord 5). The slit 8 is a narrow slit that can be inserted through the holding portion 7 formed of a thin thread. And each holding | maintenance part 7 is penetrated by the slit 8, is exposed to the other side of the screen 2, and the raising / lowering cord 5 is penetrated by the holding | maintenance part 7 exposed to the other side. Since the holding part 7 penetrates the screen 2 through such a narrow slit 8, light leakage from the penetration part is suppressed to a minimum, and a high light shielding property is maintained. In the plan view of FIG. 2, for convenience of illustration, the slit 8 is expressed by being slightly recessed from the crease 9, but it is not necessary to have such a shape, and actually, for example, the slit 8 and the crease 9 are used. Are collinear (that is, the slit 8 is not recessed from the crease 9).

  As shown in FIG. 4, as a method for inserting the lifting / lowering cord 5 through the holding portion 7, the first and second pitch holding cords 6a and 6b are passed through the slits 8 of the first and second screens 2a and 2b.
