[First Embodiment]
(Overall structure of horizontal blind)
FIG. 1 is a perspective view showing a schematic configuration of a horizontal blind according to a first embodiment of the present invention. The horizontal blind shown in FIG. 1 includes a plurality of slats 4 via ladder cords 9L, 9R, and 9M suspended from support mechanisms 5 disposed on the left end side / right end side and the center side of the head box 1, respectively. The bottom rail 8 is suspended and supported at the lower ends of the ladder cords 9L, 9R, and 9M.

  Further, each of the support mechanisms 5 on the left and right ends is provided with elevator tapes 10L and 10R hanging from the head box 1 alongside the ladder cords 9L and 9R on the indoor side, respectively, and bottoms at the lower ends of the elevator tapes 10L and 10R. Rail 8 is attached. On the other hand, the support mechanism 5 on the center side has a lifting tape 10M suspended from the head box 1 alongside the ladder cord 9M on the outdoor side, and a bottom rail 8 is attached to the lower end of the lifting tape 10M. Each support mechanism 5 is inserted with a square rod-shaped drive shaft (not shown).

  In each support mechanism 5, a tilt drum equipped with a suspension member that supports the upper ends of the ladder cords 9L, 9R, 9M is rotatably supported (not shown), and the drive shaft is supported by the tilt drum. Are inserted so that they cannot rotate relative to each other. Therefore, when the drive shaft is rotated, the tilt drum is rotated, and the angles of the multi-stage slats 4 suspended and supported by the ladder cords 9L, 9R, and 9M are adjusted.

  Further, in each support mechanism 5, a take-up shaft on which the upper ends of the lifting tapes 10L, 10R, 10M for attaching the lower ends to the bottom rail 8 are attached so as to be able to take up or rewind is not rotatable relative to the tilt drum. (Not shown), and the drive shaft is inserted into the winding shaft so as not to be relatively rotatable.

  On the right end side of the head box 1, there is provided a substantially circular operation unit 21 having a concave and convex engaging groove inside so that the operation cord 20 can be hooked with high friction. The operation unit 21 is configured such that its central axis is rotatable by operation of the operation cord 20, and this central axis is connected to a gear mechanism 22 provided at the right end portion in the head box 1. The gear mechanism 22 is connected to the drive shaft, and is configured to transmit the rotation of the central axis of the operation unit 20 to the rotation of the drive shaft. The operation unit 20 may have any form as long as it can be transmitted to the rotation of the drive shaft. For example, the operation unit 20 may be configured by a pulley having the drive shaft as a central axis directly. Alternatively, the operation cord 20 may be configured to hang an endless ball chain or an endless string.

  Therefore, by rotating the central axis of the operation unit 21 by operating the operation cord 20, the rotation is transmitted to the drive shaft and supported by the ladder cords 9L, 9R, and 9M via the support mechanisms 5. The angle of the multi-stage slats 4 can be adjusted, and the lifting tapes 10L, 10R, and 10M attached to the bottom rail 8 at the lower ends thereof are inserted into the head box 1 through the support mechanisms 5. By pulling in and pulling out from the head box 1, the slat 4 can be raised and lowered by raising and lowering the bottom rail 8.

  A stopper device (not shown) can be provided for the drive shaft connected to the gear mechanism 22. This stopper device drives the lifting tape 10L, 10R, 10M to prevent the lifting / lowering tapes 10L, 10R, 10M from moving due to the weight of the bottom rail 8 or the slat 4 when the bottom rail 8 is lifted by operating the operation cord 20 and then released. It performs a known function of locking the rotation of the shaft.

  Here, with reference to FIG. 2, the slat-shaped structural example suspended from the support mechanism 5 of the center part side in the horizontal blind of this embodiment is demonstrated as a representative. In the example shown in FIG. 2 (a), the elevating tape 10M is suspended along the front-rear direction end of the slat 4, and the elevating tape 10M alternates with respect to the two wefts 9a, 9b intersecting between the ladder cords 9M. It is configured to be knitted and inserted. Further, in the example shown in FIG. 2 (b), a notch 4a is provided at the outdoor edge of each slat 4, and the slat 4 is inserted between two intersecting wefts 9a and 9b in the ladder cord 9M. The crossing part of 9a, 9b is engaged with the notch 4a, and the elevating tape 10M is configured to be inserted between the wefts 9a, 9b at the position of the notch 4a.

  Furthermore, instead of engaging with the notches 4a, an insertion hole may be provided in the vicinity of the front-rear direction end of each slat 4, and the lifting / lowering cord 10M may be inserted into the insertion hole and suspended. A ring-shaped guide member may be provided at a predetermined interval, and the elevating tape 10M may be inserted into the guide member. Therefore, the elevating tape 10M can bring the hanging from the support mechanism 5 close to the ladder cord 9M by various methods.

  Similarly, with respect to the elevating tapes 10L and 10R, the hanging from the support mechanism 5 can be brought close to the ladder cords 9L and 9R by various methods.

  By the way, when the elevating tape 10M and the ladder cord 9M led out from the support mechanism 5 at a predetermined interval in the vicinity of the head box 1 are guided near the slat 4 so as to hang down, the elevating tape 10M and the ladder cord 9M are provided. A reciprocal force related to the drooping occurs. In this state, the edge of the lifting tape 10M makes point contact with the wefts 9a and 9b and the ring-shaped guide member. For this reason, the wefts 9a and 9b and the ring-shaped guide member are damaged by the edge of the elevating tape 10M, and the durability thereof is lowered.

  Therefore, in the horizontal blind according to the present embodiment, as shown in FIG. 1, among the multi-stage slats 4 suspended and supported via the ladder cord 9M, the lifting tape 10M suspended from the head box 1 is connected to the ladder cord 9M. A first guide member 30 is provided for a predetermined slat 4 guided in the vicinity of the first guide member 30. The first guide member 30 is provided on the slat 4 in which the elevating cord 10M suspended from the head box 1 is first guided near the ladder cord 9M. In FIG. 1, the example which provides the 1st guide member 30 in the uppermost slat 4 is shown. Hereinafter, with reference to FIG. 3 thru | or FIG. 5, the structure of the 1st guide member 30 of one Example and its effect | action and effect are demonstrated.

(First guide member)
FIG. 3 is a perspective view showing a schematic configuration of the first guide member 30 according to the embodiment of the present invention. 4A and 4B are a side view and a plan view illustrating a schematic configuration of the first guide member 30 according to the embodiment. And FIG. 5 is a top view explaining the effect | action and effect of the 1st guide member 30 of one Example.

  The first guide member 30 of the present embodiment is configured to be attachable from the bottom surface side of the slat 4 and is formed of a synthetic resin material. As shown in FIG. 3, the first guide member 30 has a substantially U-shaped main body portion 35 bent according to the curved surface shape of the slat 4. In order to allow the first guide member 30 to be attached from the bottom surface side of the slat 4, upright walls 36 that come into contact with the front and rear edges of the slat 4 are provided at four locations. In addition, a locking piece 31 protrudes inward of the main body 35 on each standing wall 36, so that the slat 4 can be elastically deformed and the first guide member 30 can be attached from the bottom surface side of the slat 4. It has become.

  Further, the first guide member 30 is provided with a notch 32. For example, when the slat 4 is provided with a notch 4a (see FIG. 2B), an insertion hole (instead of the notch 4a ( When the notch 32 is provided, the first guide member 30 is attached from the bottom surface side of the slat 4. Therefore, when the slat 4 is not provided with the notch 4a or the insertion hole, and the lifting tape 10M is configured to be inserted between the wefts 9a and 9b or the ring-shaped guide member, the notch 32 is unnecessary. is there. However, the provision of the notch 32 is effective in that the first guide member 30 having the same shape can be applied in common regardless of the presence or absence of the notch of the slat 4 or the insertion hole.

  In addition, a recess 34 is provided in the approximate center of the main body 35 of the first guide member 30. For example, when the slat 4 is inserted between the weft yarns 9a and 9b, the concave portion 34 presses the weft yarns 9a and 9b so as not to be damaged. Therefore, the first guide member 30 can be attached from the bottom surface side of the slat 4 after the slat 4 is supported by the wefts 9a and 9b of the ladder cord 9M.

  By the way, as described above, when the elevating tape 10M and the ladder cord 9M led out from the support mechanism 5 in the vicinity of the head mechanism 1 are guided near the slat 4 so as to hang down, the edge of the elevating tape 10M is obtained. Since the durability of the weft yarns 9a and 9b and the ring-shaped guide member may be reduced depending on the portion, the first guide member 30 is provided with the first guide member 30 from the front-rear direction end of the slat 4 in order to improve the durability. A pair of projecting pieces 33 projecting is formed.

  As shown in FIG. 4A, each of the pair of projecting pieces 33 is configured as a pair of plate-like pieces extending in a substantially vertical direction and substantially parallel to the slat 4, and also when the slat 4 is rotated. The edges of the lifting tape 10M are always in contact with the inner surfaces of the pair of protruding pieces 33.

  And as shown in FIG.4 (b), the width d between a pair of protrusion pieces 33 is formed so that it may become narrower than the tape width W of the raising / lowering tape 10M.

  Therefore, for example, as shown in FIG. 5, when the lifting tape 10M is inserted at the position of the notch 32 between the weft yarns 9a and 9b connected between the pair of ladder cords 9M, the lifting tape 10M is elastically shaped into a substantially U-shape. Deform. That is, when the elevating tape 10M and the ladder cord 9M led out from the support mechanism 5 at a predetermined interval in the vicinity of the head box 1 are guided by the first guide member 30 so as to hang down, as shown by the arrows in the figure. Although there is a reciprocal force related to the droop that occurs between the lifting tape 10M and the ladder cord 9M, the lifting tape 10M and the weft yarns 9a, 9b of the ladder cord 9M are in point contact when there is no first guide member 30. On the other hand, when the first guide member 30 is provided, the lifting tape 10M and the weft yarns 9a, 9b of the ladder cord 9M come into surface contact.

  As a result, the first guide member 30 applies the pressing force against the weft threads 9a and 9b of the ladder cord 9M by the edge of the lifting tape 10M due to the reciprocal force related to the droop that occurs between the lifting tape 10M and the ladder cord 9M. It can be relaxed and its friction can be reduced, thereby improving its durability.

  Even if a reciprocal force related to the droop that occurs between the elevating tape 10M and the ladder cord 9M is generated, the pair of protruding pieces 33 of the first guide member 30 receives the reciprocal force once. There is also an action of relieving the pressing force of the ladder cord 9M against the wefts 9a, 9b by the edge of 10M. For this reason, even when the elevating tape 10M is constituted by a string-like elevating cord, the pressing force of the ladder cord 9M against the wefts 9a, 9b is relaxed, and the durability is improved as compared with the case where the first guide member 30 is not provided. Can be made.

(Second guide member)
Although the example in which the first guide member 30 has the pair of protruding pieces 33 has been described so far, even if a reciprocal force related to the droop that occurs between the lifting tape 10M and the ladder cord 9M is generated, Since the pair of projecting pieces 33 of the guide member 30 once receive the reciprocal force, the pressing force against the ring-shaped guide member 13 by the edge of the elevating tape 10M is also reduced. For this reason, for example, as shown in FIGS. 6A and 6B, when the horizontal blind is configured by using the second guide member 30a and / or the second guide member 30b having one protruding piece 33 In addition, there is an effect of improving the durability of the ladder cord against the weft. For example, as shown in FIG. 1, when a plurality of lifting tapes 10R, 10L are bent from the head box 1 toward the center side from the left and right ends, respectively, and bent so as to be close to the ladder cords 9R, 9L. In addition, a second guide member 30a and a second guide member 30b are provided for each slat 4 guided in proximity to the ladder cords 9R and 9L. At this time, each of the second guide members 30a and 30b having one projecting piece 32 is arranged according to the bending direction of each of the lifting tapes 10R and 10L and is guided in the approaching direction (this book) In the case of an example, it guides to the center side from the right-and-left both ends of the said slat 4.).

  In this way, by providing the second guide members 30a and 30b, it is possible to improve the durability of the ladder cord with respect to the weft of the ladder cord by the lifting tape or the like.

[Second Embodiment]

  In this embodiment, as shown in FIG. 8, the lifting tapes 10 </ b> L and 11 </ b> R are headed along the indoor side edge in the front-rear direction of the slat 4 from the uppermost slat 4 to the predetermined slat 4 positioned below. After being suspended from the box 1, the slat 4 is suspended via a notch 4 a (or an insertion hole) provided at the indoor side edge in the front-rear direction and attached to the bottom rail 8. Further, as shown in FIGS. 8 and 9, the lifting tape 10 </ b> M is arranged along the outdoor edge of the slat 4 in the front-rear direction from the uppermost slat 4 to the predetermined slat 4 positioned below. After being hung from the bottom, the ring-shaped guide member 13 provided on the ladder cord 9M hung along the outdoor edge of the slat 4 in the front-rear direction is inserted and hung and attached to the bottom rail 8. Yes. The ring-shaped guide member 13 is provided on a ladder cord 9M that hangs down along the outdoor edge at a predetermined interval corresponding to the position of each slat 4, and has a sufficiently low frictional resistance against the movement of the elevating tape 10M. Made of material.

  Also in this embodiment, among the multi-stage slats 4 suspended and supported via the ladder cord 9M, the lifting tape 10M suspended from the head box 1 is guided in the vicinity of the ladder cord 9M. A first guide member 30 is provided for the slat 4. Further, as shown in FIG. 8, the second guide members 30a and 30b can be installed at a plurality of locations in the vertical direction of each of the elevating tapes 10R and 10L.

  In this way, the first guide member 30 can be installed at a position other than the uppermost slat 4, and further, the first guide member 30 is also inserted into the ring-shaped guide member 13 and suspended. By providing the guide member 30, the pressing force against the ring-shaped guide member 13 of the ladder cord 9M by the edge of the lifting tape 10M due to the reciprocal force related to the droop that occurs between the lifting tape 10M and the ladder cord 9M is provided.
