Description

The present invention relates to slats of multiple stages through the ladder cord from the headbox in the production how lateral blind for suspension support.

  In the horizontal blind, a ladder cord is supported by operating a ladder cord suspension device arranged in the head box with an operation device, with multiple slats supported by a plurality of ladder cords suspended from the head box. The slats can be rotated in the same phase via the.

  Also, a bottom rail is attached to the lower end of the ladder cord, and a lower end of an elevating cord hanging from the head box is attached to the bottom rail. And by raising / lowering a raising / lowering cord with the raising / lowering apparatus in a head box by operation of an operating device, a bottom rail can be raised / lowered and a slat can be raised / lowered.

  As one type of such a horizontal blind, there is one in which a plurality of lifting cords are suspended and supported in front and rear of a slat without being inserted into the slat so that the bottom rail can be lifted and lowered.

  By adopting such a configuration, it is not necessary to provide a lifting / lowering cord insertion hole in each slat, so that light leakage from the insertion hole does not occur. Further, since the lifting / lowering cord is not inserted into each slat, each slat can be rotated to a substantially vertical direction when the slat is fully closed, so that the light shielding property can be improved.

  Patent Document 1 discloses a ladder cord in which a weft at each stage is composed of two wefts intersecting at an intermediate portion. The crossing directions of the wefts at each stage are the same in all the wefts at each stage.

  In Patent Document 2, in a horizontal blind in which an elevating cord is not inserted into a slat, a slat is inserted between the wefts where the ladder cord intersects, and a locking recess of the slat is engaged with the intersecting portion of the weft, so that the slat against the ladder cord A horizontal blind is disclosed which prevents the longitudinal displacement of the horizontal blind.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the horizontal blind shown in FIGS. 1 and 2, a plurality of ladder cords 2 (three in FIG. 1) are suspended from the head box 1 at equal intervals, and the ladder cord 2 supports a plurality of slats 3. Has been.

  Above each ladder cord 2, a support member 4 is disposed in the head box 1, and a ladder cord suspension shaft 5 is rotatably supported by the support member 4, and the ladder cord suspension shaft 5 is supported on the ladder cord suspension shaft 5. The upper end of the ladder cord 2 is attached. When the ladder cord suspension shaft 5 is rotated, the slats 3 are rotated in the same phase via the ladder cord 2.

  A hexagonal bar-shaped angle adjusting shaft 6 is inserted into the ladder cord suspension shaft 5 so as not to be relatively rotatable, and one end of the angle adjusting shaft 6 is fitted to the output shaft of the operating device 7 provided at the right end of the head box 1. Are combined.

  A gear mechanism is disposed in the operating device 7, and an input shaft 8 of the gear mechanism protrudes obliquely downward from the head box 1 toward the indoor side. An operation rod 10 is suspended and supported at the tip of the input shaft 8 via a universal joint 9.

  With such a configuration, the angle adjustment shaft 6 is rotated via the operation device 7 by the rotation operation of the operation rod 10, and the ladder cord suspension shaft 5 is rotated integrally with the angle adjustment shaft 6.

  In the vicinity of the hanging position of the ladder cord 2, a plurality of lifting cords 11 are suspended from the head box 1. For example, when three lifting / lowering cords 11 are suspended, the lifting / lowering cords 11 suspended from both sides of the head box 1 are suspended along the warp of the ladder cord 2 on the outdoor side of the slat 3 and the head box. A lifting / lowering cord 11 that hangs down from an intermediate portion 1 is suspended along the warp of the ladder cord 2 on the indoor side of the slat 3.

  A bottom rail 12 is attached to lower ends of the ladder cord 2 and the lifting / lowering cord 11. And if the raising / lowering cord 11 is pulled up, the bottom rail 12 will be pulled up and the slat 3 will be pulled up.

  The upper end of the lifting / lowering cord 11 is guided into the head box 1 and is also guided to the right end side of the head box 1 in FIG. Then, a stopper device 13 provided in the head box 1 and the input shaft 8 of the operating device 7 are passed through the operating rod 10 and below the gripping portion attached to the lower end of the operating rod 10. Attached to the code equalizer 14.

  With such a configuration, when the cord equalizer 14 is pulled downward, the lifting cords 11 are pulled out from the head box 1 with the same length, and the bottom rail 12 is pulled up while maintaining the horizontal direction.

  The stopper device 13 has a function of preventing the lifting / lowering cord 11 from moving due to the weight of the bottom rail 12 and the slat 3 after the lifting / lowering cord 11 is pulled out, and preventing the bottom rail 12 and the slat 3 from dropping their own weight. . Therefore, the bottom rail 12 and the slat 3 are held in a state where they are pulled up to a desired height.

  Further, when the lifting / lowering cord 11 is pulled out from the state in which the bottom rail 12 and the slat 3 are prevented from dropping their weight, the operation of the stopper device 13 is released, and the bottom rail 12 and the slat 3 are allowed to drop by their own weight. It has become. Accordingly, the bottom rail 12 and the slat 3 can be lowered to the lower limit position.

  Next, the structure of the ladder cord 2 and the raising / lowering cord 11 which support the said slat 3 is demonstrated.

  As shown in FIG. 3, the ladder cord 2 includes a pair of warp yarns 15a and 15b and a weft yarn that forms a plurality of steps between the warp yarns 15a and 15b. The wefts at each stage are composed of two wefts 16a and 16b (a set of wefts) for supporting the slat 3.

  Each weft thread 16a, 16b is formed at a position spaced apart from the warp threads 15a, 15b in the vertical direction so that an intersecting portion 17 intersecting each other is formed at the intermediate portion. That is, in one warp (first warp) 15a, the weft 16a is attached below the weft 16b, and in the other warp (second warp) 15b, the weft 16b is attached below the weft 16a.

  Further, in the crossing portion 17, in FIG. 3, the state in which the weft 16a is positioned on the near side and the state in which the weft 16b is positioned on the near side are alternately positioned one by one.

  The warp yarns 15a and 15b are braided cords formed by a knitting machine for forming the ladder cord 2, and the weft yarns 16a and 16b are formed by yarns reciprocating between the warp yarns 15a and 15b while being knitted into the warp yarns 15a and 15b. Is done.

  And as shown in FIG. 6, the said raising / lowering cord 11 is penetrated by the triangular raising / lowering cord insertion space A1 formed between one warp 15a, weft 16a, 16b, and the cross | intersection part 17, The said slat 3 The other warp thread 15b is inserted into the slat insertion space A2 formed between the weft threads 16a and 16b and the intersecting portion 17.

  The slat 3 is formed with a notch 18 at one edge in the width direction, and the notch 18 is engaged with the intersecting portion 17 or the weft threads 16a and 16b in the longitudinal direction of the slat 3 with respect to the ladder cord 2. Deviation can be prevented.

  As shown in FIG. 4, the lifting / lowering cords 11 are alternately inserted into the respective stages, that is, the sets of wefts 16a and 16b from the left and right directions. More specifically, the lifting / lowering cord 11 is inserted from the direction in which the upper weft 16a of the wefts 16a and 16b forming the lifting / lowering cord insertion space A1 is located at the intersection 17.

  In FIG. 4, in the uppermost weft yarns 16a and 16b, the weft yarn 16b is positioned on the near side at the intersection 17, so that the lifting cord 11 is inserted into the lifting cord insertion space A1 from the near side.

  Next, in the weft yarns 16a and 16b one level below, the weft yarn 16b is positioned on the rear side at the intersection 17, so that the lifting cord 11 is inserted into the lifting cord insertion space A1 from the rear side.

  In this manner, the lifting / lowering cords 11 are alternately inserted into the lifting / lowering cord insertion spaces A1 of the respective stages in the left-right direction in FIG.

  The reason why the lifting / lowering cord 11 is inserted as described above is that when the two wefts 16a and 16b of each step of the ladder cord 2 are formed so as to obliquely intersect in the vertical direction along a substantially vertical plane, both wefts 16a , 16b is opened in the left-right direction.

  When the lifting / lowering cord 11 is to be inserted into the lifting / lowering cord insertion space A1 between the weft threads 16a and 16b, when the lifting / lowering cord 11 is inserted into the upper / lowering cord insertion space A1 from right to left, for example, the lower lifting / lowering cord is inserted. This is because when the insertion space A1 is inserted from left to right, the assembly workability is good.

  Further, as shown in FIG. 5, if the crossing state of the wefts 16a and 16b is the same at the crossing portion 17 of the wefts 16a and 16b at each stage, the direction in which the lifting and lowering cord 11 can be easily inserted into the lifting and lowering cord insertion space A1 at each stage. Are in the same direction. However, if the lifting / lowering cord 11 is manually inserted into the lifting / lowering cord insertion space A1 of the wefts 16a and 16b at each stage from the same direction, the insertion operation becomes complicated.

  However, in this embodiment, since the position in the left-right direction of the intersecting portion 17 of the weft yarns 16a, 16b of each step of the ladder cord 2 is changed for each step, the direction in which the lifting / lowering cord 11 can be easily inserted into the lifting / lowering cord insertion space A1 The wefts 16a and 16b at each stage are alternately switched in the left-right direction.

  Therefore, when the lifting / lowering cord 11 is inserted between the wefts 16a and 16b, it can be alternately inserted in the left-right direction between the wefts 16a and 16b at each stage. Therefore, it is easy to insert the lifting / lowering cord 11 into the ladder cord 2.

  Further, when the lifting / lowering cord 11 is inserted into the lifting / lowering cord insertion space A1 formed by the uppermost wefts 16a and 16b shown in FIG. 4 from the opposite side, that is, from the rear side in FIG. As a result, it moves to the slat insertion space A2 on the warp yarn 15b side. Then, when the slat 3 is inserted as shown in FIG. 6, the lifting / lowering cord 11 slips between the wefts 16 a and 16 b at the crossing portion 17 and directly contacts the notch 18 of the slat 3.

  Therefore, since the lifting / lowering cord 11 and the edge of the slat 3 are rubbed with each other during the lifting / lowering operation of the slat, the lifting / lowering cord 11 is easily worn.

  Therefore, when the lifting / lowering cord 11 is inserted from the left / right direction of the ladder cord 2 as described above, the lifting / lowering cord 11 is blocked by the crossing portion 17 even if the lifting / lowering cord 11 moves to the slat insertion space A2. It becomes possible to prevent rubbing with the edge.

  Further, since the positions of the respective weft threads 16a and 16b in the horizontal direction of the blind are reversed at the intersecting portions 17 of the weft threads 16a and 16b at each stage, as shown in FIG. When alternately inserted from the direction, it is possible to prevent the lifting / lowering cord 11 from passing through at the intersections 17 of the respective stages.

  On the other hand, in FIG. 4, when the direction in which the lifting / lowering cord 11 is easily inserted is opposite to the lifting / lowering cord insertion space A1 of the wefts 16a and 16b in each stage, the opposite direction to each lifting / lowering cord insertion space A1. May be inserted alternately. In this case, although it will be in the state which permits passage of the raising / lowering cord 11 in the intersection part 17 of each step | level, the insertion operation | work to the ladder cord 2 of the raising / lowering cord 11 becomes easy.

  Next, the operation of the ladder cord 2 configured as described above will be described.

  7 to 13 show a procedure for assembling the slat 3 and the lifting / lowering cord 11 through the ladder cord 2 shown in FIG.

  As shown in FIG. 7, a jig 19 is used to insert a slat between the intersecting portion 17 of the weft threads 16a and 16b of the ladder cord 2 and one warp thread 15b. The jig 19 has a large number of operation shafts 20 that can be inserted between the wefts 16 a and 16 b at each stage, and is formed with insertion holes 21 through which the slats 3 are inserted.

  Then, while holding one warp 15b of the ladder cord 2 with the holding device 22, as shown in FIG. 8, the operation shaft 20 is inserted between the wefts 16a and 16b.

  Next, as shown in FIG. 9, the jig 19 is moved to the warp yarn 15 a side, the intersecting portion 17 is moved to the warp yarn 15 a side by the operation shaft 20, and the interval between the intersecting portion 17 and the warp yarn 15 b is greater than the width of the slat 3. The slat insertion space A2 is formed as follows.

  Next, as shown in FIG. 10, when the slat 3 is inserted into the insertion hole 21 of the jig 19, the slat 3 is inserted into the slat insertion space A2.

  Next, the jig 19 is removed from the ladder cord 2, and as shown in FIGS. 11 and 12, the lifting cord 11 is alternately inserted into the lifting cord insertion space A1 from the left and right directions and is strained. Then, as shown in FIG. 13, the lifting / lowering cord 11 is held between the wefts 16a and 16b of each stage in the vicinity of the warp 15a.

  In this way, the slat 3 and the lifting / lowering cord 11 are inserted into the ladder cord 2, and the upper ends of the warp threads 15a, 15b of the ladder cord 2 are attached to the ladder cord suspension shaft 5 in the head box 1 and the warps 15a, The lower end of 15b is attached to the bottom rail 12. In addition, the lower end of the lifting / lowering cord 11 is attached to the bottom rail 12, and the upper end portion is connected to the cord equalizer 14 through the stopper device 13 and the operation rod 10 in the head box 1.
