  Hereinafter, various embodiments of the present invention will be described. Various characteristic items shown in the following embodiments can be combined with each other.

(First embodiment)
The shielding apparatus of 1st Embodiment of this invention is demonstrated using FIG. The shielding device of this embodiment includes two pleated fabrics (first and second shielding materials) 12 and 22 that are suspended from the head box 1 and can be folded in a zigzag shape in the vertical direction. The two pleated fabrics 12 and 22 are arranged side by side in the front-rear direction and are suspended from substantially the same position on the lower surface of the head box 1. The pleated fabrics 12 and 22 are separate fabrics that are not welded or bonded to each other and are separable from each other. Since the pleated fabric 12 has a larger pitch between the folds than the pleated fabric 22, the pleated fabric 12 is positioned between the pleated fabrics 12, 22 with the crease 9 positioned as shown in FIGS. An air layer S is formed on the surface to enhance heat insulation. Moreover, since the space | interval between the pleat fabrics 12 and 22 is very narrow (or in contact) in the position of the crease 9, the vertical convection between the pleat fabrics 12 and 22 is suppressed, and heat insulation is carried out. The nature is further enhanced. The length of the holding portion (pico) 7 that regulates the warp yarn of the pitch holding cord 6 and the lifting / lowering cord 5 is the distance between the warp yarn of the pitch holding cord 6 and the lifting / lowering cord 5 is folded two pleated fabrics 12 and 22. It is longer than the width of the state, and the two pleated fabrics 12, 22 can be folded smoothly.

  The bottom rail 3 is attached to the lower ends of the pleated fabrics 12 and 22. One end of a lifting / lowering cord 5 is attached to the bottom rail 3. The other end of the lifting / lowering cord 5 passes through the head box 1 and hangs down from a cord outlet 19 provided at one end of the head box 1. A code equalizer 8 is attached to the tips of the plurality of lifting cords 5 hanging from the cord outlet 19, and the plurality of lifting cords 5 can be operated collectively by grasping the code equalizer 8. A stopper (not shown) is provided in the vicinity of the cord outlet 19 or in the head box 1, and the bottom rail 3 can be held at a desired position by preventing the lifting cord 5 from moving when the lifting cord 5 is not operated. ing. In the present embodiment, the lifting / lowering cords 5 are provided at two locations in the width direction of the bottom rail 3, one of which is inside the room of the pleated fabrics 12 and 22 and the other is inside the room of the pleated fabrics 12 and 22. By being provided, when the bottom rail 3 is moved up and down, the bottom rail 3 does not tilt in the front-rear direction. The number of the lifting / lowering cords 5 is not particularly limited. For example, when the number of the lifting / lowering cords 5 is three, the central lifting / lowering cord 5 is arranged inside the room, and the lifting / lowering cords 5 at both ends are arranged outside the room. The arrangement can be reversed.

  A pitch holding cord 6 is provided at a position facing each lifting cord 5 across the pleated fabrics 12 and 22. The pitch holding cord 6 has one end attached to the head box 1 and the other end attached to the bottom rail 3. The pitch holding cord 6 is provided with a plurality of annular holding portions 7 at predetermined intervals. When the pleat fabrics 12 and 22 are inserted into the holding portions 7, a part of the holding portion 7 forms the lifting / lowering cord insertion portion 7 a on the lifting / lowering cord 5 side. When the lifting / lowering cord 5 is inserted through the lifting / lowering cord insertion portion 7 a, the maximum distance between the lifting / lowering cord 5 and the pitch holding cord 6 is regulated by the holding portion 7. The pleated fabrics 12 and 22 sandwiched between the lifting / lowering cord 5 and the pitch holding cord 6 are also restricted from separating in the front-rear direction. Therefore, in this embodiment, the raising / lowering cord 5 and the pitch holding cord 6 connected by the holding portion 7 function as “a separation suppressing unit” in the claims.

  As shown in FIGS. 1B to 1C, the holding portion 7 is inserted through the pleated fabrics 12 and 22 at the fold line 9 in the room outside direction. A pinhole is formed in the pleated fabrics 12 and 22 at the insertion portion of the holding portion 7. The pinhole may be formed in advance or may be formed when the holding portion 7 is inserted. In FIGS. 1B to 1C, since the height positions of the creases 9 of the pleated fabrics 12 and 22 are the same, there is a possibility that light leakage through the pinhole may occur. In order to suppress such light leakage, the height position of the crease 9 of the pleated fabrics 12 and 22 may be shifted.

Here, the dough part assembly process of the manufacturing method of the shielding apparatus of this embodiment is demonstrated.
First, the pleated fabrics 12 and 22 are produced by pleating the fabric for the pleated fabric 12 and the fabric for the pleated fabric 22.
Next, the holding portion 7 is inserted into the pleated fabrics 12 and 22 in a state where the pleated fabrics 12 and 22 are overlapped to form the lifting / lowering cord insertion portion 7a.
Next, the fabric part assembly is completed by inserting the lifting / lowering cord 5 or the dummy cord through the lifting / lowering cord insertion portion 7a.
Thereafter, the product can be lifted and lowered through a product assembly process in which the pleated fabrics 12 and 22 are suspended from the head box 1. When the dummy cord is inserted into the lifting / lowering cord insertion portion 7a in the fabric portion assembly, the lifting / lowering cord insertion portion 7a is lifted / lowered by joining the lifting / lowering cord 5 to the dummy cord and pulling out the dummy cord in the product assembly process. Insert cord 5 through.

  Thus, in this embodiment, since the pleated fabrics 12 and 22 are not welded or bonded, the user can freely select and order the fabric for the pleated fabric 12 and the fabric for the pleated fabric 22. It becomes easy to produce a product that suits your taste. In addition, the pleated fabric that has been welded or bonded has a high inventory risk, but according to the present embodiment, such a risk can be eliminated. Further, since the pleated fabrics 12 and 22 are integrated by inserting the lifting / lowering cord 5 through the lifting / lowering cord insertion portion 7a, if foreign matter such as insects enters between the pleated fabrics 12 and 22, the pleating fabric 12 and 22 is lifted / lowered. By pulling out the lifting / lowering cord 5 from the cord insertion portion 7a, the integrated state of the pleated fabrics 12 and 22 can be easily released. It is also possible to replace one of the pleated fabrics 12, 22 with another fabric later.
