- the slat 3 should just be inserted in the space between the crossing part 42 and the warp 5b so that the said notch part 3a (illustration omitted in FIG. 16) may oppose the crossing part 42 of the weft 41a and the weft 41d. .
- three wefts 6a, 6b, 51 may be provided in each stage.
- the weft thread 51 is spirally entangled with the weft thread 6b between about 2/3 from the warp thread 5b to the warp thread 5a.
- the said raising / lowering cord 11 (13) is inserted between the part where the weft 6b and the weft 51 are not entangled (the warp 5a side).
- the slat 3 has a weft on the warp yarn 5b side (front side) with respect to the intersecting portion of the weft yarns 6a and 6b and the intersecting portion of the weft yarns 6a and 51. It is inserted between 6a and 6b.
- the lifting cord 12 and the slat 4 are commonly used so that the weft threads 6a and 6b do not intersect in plan view at the sixth stage of the hanging portion of the lifting cord 12. Even when the fully-enclosed rotation is performed, the lifting / lowering cord 12 and the warp 5b push up the upper edge of the slat 4 in a direction in which the rising degree increases, so that the lifting / lowering cord 12 does not exist. Shielding is improved.
- the lifting cords 11 and 13 are arranged so that the wefts 6a and 6b do not intersect in plan view at the sixth level or lower of the hanging portions of the lifting cords 11 and 13, respectively.
- the slats 3 (4) may be inserted into a common space, and even during this fully fully closed rotation, the lifting and lowering cords 11 and 13 are interposed between the slats 3 and 4 and the warp 5a, so that the shielding property can be obtained. improves.
- the lifting cords 11 to 13 are embodied as horizontal blinds that are wound around the lifting and lowering winding shafts 14a to 14c by the driving force of the motor.
- the present invention is not limited to this.
- the cord equalizer 61 may be embodied as a horizontal blind of the type in which the elevating cords 11 to 13 are moved upward by pulling the cord equalizer 61 by hand.
- both the notch stages in which the elevating cords 11 to 13 are not inserted between the weft threads 6a and 6b and the notches 4a and 4b are provided at the front edge and the rear edge of the slat 4 are the uppermost
- the number of stages provided with both notch stages may be appropriately changed to other stages depending on the width of the ladder cord and the width in the front-rear direction of the lift outlet 1b.
- both notched steps may be provided from the uppermost stage to the fourth stage or from the uppermost stage to the seventh stage.
