  In the configurations described in Patent Documents 1 and 2, since it is not necessary to provide the lifting / lowering cord insertion hole in the slat, the problem of solar radiation leakage through this hole is solved. However, it has been found that with such a configuration, even if the slat is made to be in a fully closed state, the slat does not stand up sufficiently, and light leakage occurs between adjacent slats.

  The present invention has been made in view of such circumstances, and provides a horizontal blind having extremely excellent shielding properties.

  According to the present invention, an opening / closing cord hanging from the head box and a plurality of slats arranged side by side and supported by the opening / closing cord are provided, and the opening / closing cord includes a room inside and a room outside of the slat. Each of the slats and supporting the slats from inside and outside the room of the slats, the open / close cord includes warp yarns and a plurality of slat support portions arranged along the warp yarns, The slat support portion includes a flexible linear base extending from the warp and a linear hooking portion having higher rigidity than the linear base, and the linear base is more than both ends of the linear hooking portion. The slat support portion is provided on the slat so that the linear hook portion is disposed below the slat. Is engaged with the engaging portion, horizontal blinds are provided.

  The present inventors investigated the cause of light leakage between adjacent slats in the configurations described in Patent Documents 1 and 2, and in these configurations, a ladder cord in which a pair of warp yarns are connected by weft yarns. It was found that because the slats are used for supporting and tilting, the wefts interfere with the tilting and the slats do not rise sufficiently. Therefore, when intensive research was conducted to improve the rising of the slat, instead of using the ladder cord, the slat was supported substantially vertically by using the open / close cord having the slat support portion configured as described above to support the slat. It was found that it was possible to start up, and the present invention was completed.

  Hereinafter, various embodiments of the present invention will be described with reference to the drawings. The various embodiments described below can be combined with each other. In the second to third embodiments, differences from the first embodiment will be mainly described.

1. 1st Embodiment The horizontal blind 1 of 1st Embodiment of this invention is demonstrated using FIGS.
An opening / closing cord 5 is suspended from the lower surface 3 a of the head box 3, and a plurality of slats 9 arranged in the vertical direction are supported by the opening / closing cord 5. The opening / closing cord 5 includes a room-side opening / closing cord 5 a that hangs down inside the room of the slat 9 and a room-side opening / closing cord 5 b that hangs down outside the room of the slat 9. A bottom rail 7 is attached to the lower ends of the open / close cords 5a and 5b.
Each of the open / close cords 5a and 5b includes a warp 5c and a plurality of slat support portions 5d arranged along the warp 5c. The slat 9 is supported by the slat support 5d of the room inner opening / closing cord 5a and the slat support 5d of the room outer opening / closing cord 5b. In FIG. 1, ten slats 9 are supported, but the number of slats 9 is appropriately determined depending on the height of the blinds, the width of the slats 9, the interval between the slats 9 in each stage, and the like. In the present embodiment, the thickness and material of the slat 9 are not particularly limited.

  An elevating cord 13 is suspended from the lower surface 3 a of the head box 3, and one end of the elevating cord 13 is attached to the bottom rail 7. The lifting / lowering cord 13 in the center in the width direction of the head box 3 is suspended from the outside in the front-rear direction of the room inner opening / closing cord 5a adjacent to the room inner opening / closing cord 5a. Adjacent to the outdoor opening / closing cord 5b, it is suspended from the outside in the front-rear direction than the outdoor opening / closing cord 5b.

  Opening / closing cord 5p adjacent to the lifting / lowering cord 13 (in the opening / closing cord 5 in the center in the width direction of the head box 3, the opening / closing cord 5a is the opening / closing cord 5p, and in the opening / closing cord 5 at both ends in the width direction of the head box 3, The outdoor open / close cord 5b is the open / close cord 5p.) Has a connecting portion 5e through which the lifting / lowering cord 13 is slidably inserted in the vertical direction, and the lifting / lowering cord 13 is connected to the opening / closing cord 5p by the connecting portion 5e. Yes. The connecting portion 5e is, for example, a small ring called a pico. However, the connecting portion 5e does not necessarily have a ring shape, and may be any as long as the lifting / lowering cord 13 can be slidably connected to the opening / closing cord 5p. The position and pitch at which the connecting portion 5e is provided are not particularly limited as long as the lifting / lowering cord 13 can be appropriately connected to the opening / closing cord 5p, and the connecting portion 5e may be provided at a position corresponding to each slat 9. You may provide by skipping or multiple skipping. Further, the positional relationship between the connecting portion 5e and the slat 9 is not particularly limited, and the height position at which the connecting portion 5e is provided may be on either the upper side or the lower side of the slat 9, and is as high as the slat 9. Also good.

  The slat support portion 5d includes a flexible linear base portion 5d1 extending from the warp yarn 5c and a linear hook portion 5d2 having higher rigidity than the linear base portion 5d1. The linear base 5d1 is connected to the linear hook 5d2 at the approximate center in the longitudinal direction of the linear hook 5d2. As a method of making the rigidity of the linear hook portion 5d2 higher than that of the linear base portion 5d1, a method of making the diameter of the linear hook portion 5d2 larger than that of the linear base portion 5d1, or a material of the linear hook portion 5d2 can be used. There is a method of making it more rigid than the linear base portion 5d1. For example, the linear base portion 5d1 can be formed of a flexible fiber, and the linear hook portion 5d2 can be formed of a fiber having higher rigidity (harder) than the linear base portion 5d1.

  The slat 9 includes an engaging portion including a closed through-hole 9c at a position adjacent to each of the room inner edge 9a and the room outer edge 9b. As shown in FIG. 4, by inserting the end portion 5d3 of the linear hook portion 5d2 into the closed through hole 9c from the upper side of the slat 9, and placing the linear hook portion 5d2 on the lower side of the slat 9. Then, the linear hook 5d2 is engaged with the slat 9. In order to facilitate passage of the closed through hole 9c through the linear hook portion 5d2, the diameter of the closed through hole 9c is equal to or greater than the sum of the diameter of the linear hook portion 5d2 and the diameter of the linear base portion 5d1. Is slightly larger. Further, in the state in which the linear hooking portion 5d2 is engaged with the slat 9, the linear hooking portion 5d2 and the linear base portion 5d1 block the closed through hole 9c and prevent light leakage from the closed through hole 9c. If the closed through-hole 9c is too larger than the sum of the diameter of the linear hook 5d2 and the diameter of the linear base 5d1, light leakage increases, which is not preferable. Therefore, the diameter of the closed through-hole 9c is preferably 0.8 to 2 times, more preferably 1 to 1.5 times the sum of the diameter of the linear hook portion 5d2 and the diameter of the linear base portion 5d1. In addition, when the closed through-hole 9c is not circular, the diameter of a circle having an area equal to the area of the closed through-hole 9c is defined as “the diameter of the closed through-hole 9c”.

  Further, as shown in FIG. 4, (the length L from the connecting portion 5d4 of the linear base portion 5d1 and the linear hook portion 5d2 to the end portion 5d3 of the linear hook portion 5d2) / (of the linear base portion 5d1). The length S) is preferably less than 1, more preferably 0.8, 0.6 or 0.4. This is because if the value of L / S is too large, workability when the closed through-hole 9c is passed through the linear hooking portion 5d2 is deteriorated.

  As shown in FIG. 5, in the present embodiment, the lifting / lowering cord 13 is guided by a lifting / lowering cord guide portion (eg, pulley) 19 provided in the head box 3 and wound around the winding drum 21. Yes. With such a configuration, by rotating the winding drum 21, the bottom rail 7 can be raised and lowered by changing the length of the lifting cord between the head box 3 and the bottom rail 7. The winding drum 21 can be rotated by rotating the drive shaft 22. The method of rotating the drive shaft 22 is not particularly limited, and is driven by attaching an operation cord to a pulley supported so as not to rotate relative to the drive shaft 22 and pulling the operation cord to rotate the pulley. The shaft 22 may be rotated, or the drive shaft 22 may be rotated using an electric motor. In the present invention, the lifting means of the bottom rail 7 is not limited to the winding drum type lifting means as shown in FIG. 5, and the lifting code 13 inserted into the head box 3 through the lifting code guide portion 19 is used. It may be a so-called direct pulling type lifting means that pulls out from another position of the head box 3 and lifts and lowers the bottom rail 7 by changing the pulling amount.

  As shown in FIG. 5 (a), the end of the opening / closing cords 5 a, 5 b on the head box 1 side of the warp 5 c is attached to a suspension ring (not shown) rotated by the drive shaft 22. The suspension ring rotates within a predetermined movable range, and by this rotation, the warp 5c of the opening / closing cord 5b is pulled in the direction of arrow X, and the warp 5c of the opening / closing cord 5a is lowered in the direction of arrow Y. When the height difference P between the slat support portion 5d of 5b and the slat support portion 5d of the opening / closing cord 5a is equal to or greater than the width in the front-rear direction of the slat 9, the slat 9 is tilted as shown in FIG. Stands up vertically.

  In the so-called ladder cord type horizontal blind that supports the slats with a weft arranged between a pair of warp yarns, it is difficult to raise the slats substantially vertically due to the presence of the wefts. A light leak occurred. In this embodiment, since the slat 9 is supported by using the opening / closing cord 5 having the slat support portion 5d without using the ladder cord, the weft does not interfere with the rise of the slat. The slats 9 can be raised substantially vertically, and the shielding performance can be improved.

  In this embodiment, the linear base 5d1 is made of a flexible wire, and the relative angle of the linear base 5d1 to the warp 5c and the relative angle of the linear base 5d1 to the linear hook 5d2 Since it also changes easily, the slats 9 can be smoothly raised substantially vertically. Specifically, in the example of FIGS. 5A to 5B, the relative angle of the linear base portion 5d1 with respect to the linear hook portion 5d2 in the outdoor opening / closing cord 5b is as shown in FIG. 5A. The angle changes from about 90 degrees to about 0 degrees in the state of FIG. 5 (b), and the relative angle β of the linear base portion 5d1 with respect to the warp 5c in the room inner side opening / closing cord 5a is about about in the state of FIG. By changing from 30 degrees to about 120 degrees in the state of FIG. 5B, the slats 9 can rise smoothly.

This embodiment can also be implemented in the following aspects.
In the above embodiment, the two linear base portions 5d1 are connected to the linear hook portion 5d2, but the number of the linear base portions 5d1 may be one.
In the above embodiment, the linear hooking portion 5d2 is connected to the tip of the linear base portion 5d1 and the slat support portion 5d has a T shape. The linear hooking portion 5d2 may be connected to the linear base portion 5d1 at a position close to 5c to form a cross shape (or an X shape).
In the above embodiment, the same number of the closed through-holes 9c inside the room and the closed through-holes 9c outside the room are provided at the same position in the width direction of the slat 9, but the closed through-holes 9c inside the room and the room The position of the outer closed through hole 9c may be shifted in the width direction of the slat 9, and the number of the closed through holes 9c inside the room and the closed through holes 9c outside the room may not be the same.

2. Second Embodiment Next, a horizontal blind according to a second embodiment of the present invention will be described with reference to FIG.
The horizontal blind according to the present embodiment is similar to the first embodiment. In the first embodiment, the linear base 5d1 is formed on the linear hook 5d2 at the approximate center in the longitudinal direction of the linear hook 5d2. In contrast, in the present embodiment, as shown in FIG. 6, the linear base 5d1 is connected to the linear hook at a position shifted from the longitudinal center of the linear hook 5d2. Has been.
In this embodiment, when passing the closed through hole 9c through the linear hooking portion 5d2, the closed through hole 9c is inserted from the end 5d31 side far from the connecting portion 5d4, and then the connecting portion 5d4. By inserting the end portion 5d32 closer to the end into the closed through hole 9c, the entire linear hook portion 5d2 is disposed below the slat 9. If the closed through-hole 9c is passed through the linear hook portion 5d2 in this manner, (the length L to the end portion 5d32 of the linear hook portion 5d2) / (the length S of the linear base portion 5d1). Since the value of is not different from that of the first embodiment, the workability when the closed through-hole 9c is passed through the linear hooking portion 5d2 is not deteriorated. Further, the linear hooking portion 5d2 is less likely to come out of the closed through-hole 9c by the distance from the connecting portion 5d4 to the far end 5d31, and the linear hooking portion 5d2 is more than the first embodiment. Can receive large loads. Therefore, according to the present embodiment, the load resistance of the linear hook portion 5d2 can be increased without deteriorating the workability when the closed through-hole 9c is passed through the linear hook portion 5d2.

3. Third Embodiment Next, a horizontal blind according to a third embodiment of the present invention will be described with reference to FIGS.
The horizontal blind according to the present embodiment is similar to the first embodiment. In the first embodiment, the engaging portion is a closed through hole 9c, whereas in the present embodiment, the engaging portion 9d is a through-hole. It consists of a hole 9d1 and a notch 9d2 extending from the through hole 9d1 to the edge of the slat 9. The notch 9d2 includes a slit portion 9d21 having a width that prevents the slat support portion 5d from coming out of the through hole 9c, and a tapered portion 9d22 having a width that widens from the slit portion 9d21 toward the edge of the slat 9.

  In the first embodiment, the linear hooking portion 5d2 is engaged with the slat 9 by passing the closed through hole 9c through the linear hooking portion 5d2. However, in the present embodiment, the same method is applied. In addition to being able to be combined, the linear base portion 5d1 is slid in the direction of the arrow Z in FIG. 8 to be arranged in the through hole 9d1 via the taper portion 9d22 and the slit portion 9d21. The hanging portion 5d2 can be engaged with the slat 9. By guiding the linear base portion 5d1 to the slit portion 9d21 by the tapered portion 9d22, the linear base portion 5d1 can be easily inserted into the slit portion 9d21. According to such a method, it is easy to engage the linear hooking portion 5d2 with the slat 9, and the workability is excellent. In the first embodiment, as the length L / length S shown in FIG. 4 increases, it becomes more difficult to engage the linear hooking portion 5d2 with the slat 9. Since the length of the hook portion 5d2 does not affect the workability, there is an advantage that the linear hook portion 5d2 can be designed freely.

  The diameter of the linear hooking portion 5d2 is preferably at least one times the diameter of the through hole 9d1 from the viewpoint of closing the through hole 9d1 and reducing light leakage.
