(First embodiment)
A first embodiment of the present invention will be described below with reference to the drawings. In the vertical blind shown in FIG. 1, a large number of slats 2 are supported by suspension from a hanger rail 1, and each slat 2 is supported by suspension from a runner 3 movably supported in the hanger rail 1. The slat 2 is made of a cloth having a light shielding property, and constitutes first and second slat groups G1, G2.

  In the state where the slats 2 are pulled out, half of the slats 2 out of the total number of slats 2 that are pulled out in advance along the hanger rail 1 become the first slat group G1, and the remaining half of the slats 2 Becomes the second slat group G2.

  A tilt shaft 4 is inserted into each runner 3 so as to be relatively movable in the axial direction, and both ends of the tilt shaft 4 are rotatably supported by end caps 5 a and 5 b attached to both ends of the hanger rail 1. .

  As shown in FIGS. 2 and 3, each runner 3 is rotatably supported by a suspension shaft 6 that supports the slat 2 in a suspended manner, and a hook 7 is provided at the lower end of the suspension shaft 6. Yes. A slat hanger 14 that suspends and supports the slat 2 is hung on each hook 7.

  An operating rod (operating device) 9 is suspended and supported at one end of the hanger rail 1, and when the operating rod 9 is rotated, the tilt is made via a gear mechanism (not shown) disposed in the end cap 5a. The shaft 4 is rotated. As the tilt shaft 4 rotates, the suspension shaft 6 of each runner 3 is rotated so that the slats 2 supported by the runners 3 are rotated.

  The operation cord 10 suspended from the end cap 5a is disposed so as to be able to circulate in the hanger rail 1, and is attached to the leading runner of the runner 3 that is suspended most toward the end cap 5a. Each runner 3 is connected by a spacer 11, and the maximum separation distance of each runner 3 is set by the spacer 11.

  Accordingly, if the operation code 10 is operated to move the leading runner, the subsequent runners are sequentially drawn following the leading runner, or the subsequent runners are sequentially pushed back by the leading runner. By such an operation, the slats 2 suspended and supported by the runners 3 are pulled out along the hanger rail 1 or folded on the other end side of the hanger rail 1.

  A gear mechanism 8 that rotates the suspension shaft 6 with the rotation of the tilt shaft 4 is built in the runner 3. The gear mechanism 8 is constituted by a worm mechanism including a worm 12 rotatably supported by the runner 3 and a worm wheel 13 rotatably supported by the suspension shaft 6, and the worm 12 includes the tilt shaft. 4 is inserted. The worm 12 is rotated based on the rotation of the tilt shaft 4, and when the worm 12 is rotated, the worm wheel 13 is rotated. The gear ratio of the worm 12 and the worm wheel 13 of each runner 3 is the same.

  A coil spring (torque transmission device) 15 is disposed between the upper end of the suspension shaft 6 and the upper edge of the worm wheel 13. The rotation of the worm wheel 13 is always transmitted to the suspension shaft 6 through friction caused by the biasing force of the coil spring 15.

  Further, a stopper (not shown) for setting a rotation range is provided between the suspension shaft 6 and the runner 3, and the slat 2 rotates in a direction substantially along the hanger rail 1 as the suspension shaft 6 rotates. Then, further rotation of the suspension shaft 6 in the same direction is prevented. In a state where the rotation of the suspension shaft 6 is prevented, the worm wheel 13 is idled with respect to the suspension shaft 6.

  As shown in FIG. 4, the tilt shaft 4 includes a first shaft portion 16a and a second shaft portion 16b having different cross-sectional shapes on one end side and the other end side with the center as a boundary. As shown in FIG. 2, the first shaft portion 16 a on one end side is formed in a substantially flat plate shape in cross section, and is inserted through an insertion hole 17 formed in the worm 12.

  The insertion hole 17 is formed in a shape that allows the first shaft portion 16a to idle freely in the forward and reverse directions within a range of approximately 60 degrees (rotation delay device, idle rotation means). Specifically, the insertion hole 17 has a shape with a mountain-shaped protrusion at a position facing the inner peripheral surface of the circular hole, and the first shaft portion 16a is rotated in the reverse direction from the state where the first shaft portion 16a rotates together with the worm 12. When this occurs, the first shaft portion 16 a rotates about 60 degrees with respect to the worm 12.

  Moreover, as shown in FIG. 3, the 2nd axial part 16b is provided with the concave corresponding to the mountain-shaped protrusion of the insertion hole 17 on the outer peripheral surface of the round shaft. Then, the second shaft portion 16b inserted through the insertion hole 17 is always meshed with the projection of the insertion hole 17 so that the worm 12 is rotated integrally with the second shaft portion 16b.

  With such a configuration, the runner 3 positioned on the second shaft portion 16 b of the tilt shaft 4 rotates the slat 2 by rotating the worm 12 with the rotation of the tilt shaft 4. Is reversed, the runner 3 positioned on the first shaft portion 16a starts the rotation of the worm 12 after the tilt shaft 4 has rotated approximately 60 degrees.

  Next, the operation of the vertical blind configured as described above will be described. When the operation code 10 is operated and the leading runner 3 is pulled out along the hanger rail 1, the subsequent runners 3 are sequentially pulled out at a predetermined interval. Then, after the top runner 3 is pulled out to one end of the hanger rail 1, when the operating rod 9 is operated to rotate each slat 2 in a direction along the hanger rail 1, as shown in FIG. Become.

  At this time, the slat 2 supported by suspension from the runner 3 positioned on the first shaft portion 16a becomes the first slat group G1, and the slat 2 supported by suspension from the runner 3 positioned on the second shaft portion 16b. Becomes the second slat group G2.

  FIGS. 5A to 5J show the slats of the first and second slat groups G1 and G2 until the slat 2 rotated to the fully closed state is rotated by approximately 180 degrees to be the fully closed state again. 2 shows the transition of the rotation angle.

  When the operating rod 9 is operated to rotate the slat 2 from the fully closed state of the slat 2 shown in FIG. 5 (a), the second slat group G2 is immediately rotated, but FIG. 6 (a) ( As shown in b), the first shaft portion 16a of the tilt shaft 4 rotates about 60 degrees with respect to the worm 12 of the runner 3 of the first slat group G1. For this reason, as shown in FIG.5 (b), the 1st slat group G1 is not rotated until the 2nd slat group G2 is rotated 60 degree | times.

  When the operating rod 9 is further operated in the same direction, the worm 12 is rotated together with the first shaft portion 16a as shown in FIG. 6C, and the first shaft 16a is rotated as shown in FIGS. One slat group G1 rotates with a delay of 60 degrees from the second slat group G2.

  When the second slat group G2 is rotated to a direction substantially along the hanger rail 1, further rotation of the second slat group G2 is prevented, and only the first slat group G1 rotates in the same direction. Then, as shown in FIG. 5 (e), the first and second slat groups G1, G2 are rotated to the fully closed state.

  Further, when the operating rod 9 is turned in the reverse direction from the state shown in FIG. 5 (e), the second slat group G2 is immediately turned, as shown in FIGS. 7 (a) and 7 (b). The first shaft portion 16a of the tilt shaft 4 rotates about 60 degrees with respect to the worm 12 of the runner 3 of the first slat group G1. For this reason, as shown in FIG.5 (f), the 1st slat group G1 is not rotated until the 2nd slat group G2 is rotated 60 degree | times.

  Then, when the operating rod 9 is further operated in the same direction, the worm 12 is rotated together with the first shaft portion 16a as shown in FIG. 5 (g), and the first shaft portion 16a is rotated as shown in FIGS. One slat group G1 rotates with a delay of 60 degrees from the second slat group G2.

  When the second slat group G2 is rotated to a direction substantially along the hanger rail 1, further rotation of the second slat group G2 is prevented, and only the first slat group G1 rotates in the same direction. Then, as shown in FIG. 5 (j), the first and second slat groups G1, G2 are rotated to the fully closed state.

With the vertical blind constructed as described above, the following operational effects can be obtained.
(1) By rotating the operating rod 9, the first slat group G1 and the second slat group G2 can be rotated in parallel, and the slats 2 of the first slat group G1, The slats 2 of the second slat group G2 can be rotated at different angles.
(2) When the first and second slat groups G1 are rotated from the fully closed state, the first slat group G1 can be rotated with a delay from the second slat group G2. Therefore, as shown in FIG. 8, the second slat group G2 can be rotated while maintaining the first slat group G1 in the fully closed state. Can incorporate light. Moreover, since external light can be taken in without transferring the 2nd slat group G2, indoor space S2 obstruct | occluded from the visual field from the outdoor can be expanded, and these operation can be performed easily. .
(3) As shown in FIG. 9, when the second slat group G2 is rotated to the fully closed state, the first slat group G1 is not yet rotated to the fully closed state. External light can be introduced only from the part. Moreover, since external light can be taken in without transferring the 1st slat group G1, indoor space S3 obstruct | occluded from the visual field from the outdoor can be expanded.
(Second embodiment)
10 and 11 show a second embodiment. This embodiment is a double-opening type vertical blind in which first and second slat groups G1 and G2 are folded at both ends of the hanger rail 1.

  The tilt shaft 4 is divided into a first shaft portion 18 a and a second shaft portion 18 b and is connected via a delay mechanism 19. The runner 3 that supports the second slat group G2 in a suspended manner is supported by the first shaft portion 18a, and the runner 3 that supports the first slat group G1 in a suspended manner is movable on the second shaft portion 18b. It is supported by.

The first shaft portion 18a and the second shaft portion 18b are the same as ordinary vertical blinds that do not cause idle rotation with respect to the worms of the runners 3.
As shown in FIG. 11A, the delay mechanism 19 has connecting members 21a and 21b fitted into the ends of the first shaft portion 18a and the second shaft portion 18b in the case 20. An engaging protrusion 22 is formed at the tip of the connecting member 21a, and the engaging protrusion 22 is inserted into an engaging recess 23 formed at the tip of the connecting member 21b. The engagement protrusion 22 and the engagement recess 23 are relatively rotatable within a range of approximately 60 degrees.

  With this configuration, as in the first embodiment, when the first shaft portion 18a is rotated by operating the operating rod, the second shaft portion 18b rotates until the first shaft portion 18a rotates 60 degrees. Instead, after the first shaft portion 18a is rotated 60 degrees, the first shaft portion 18a and the second shaft portion 18b are rotated together.

Therefore, when the operating rod is operated from the state in which the first and second slat groups G1 and G2 are pulled out and rotated to the fully closed state, the first slat group G1 rotates 60 degrees behind the second slat group G2. Moved. By such an operation, the same effect as the first embodiment can be obtained.
(Third embodiment)
12 and 13 show a third embodiment. The tilt shaft 4 of this embodiment has the same cross-sectional shape over its entire length, and its cross-sectional shape is a flat plate shape as shown in FIG.

  As shown in FIG. 13A, the insertion hole 24a of the worm 12 of the runner 3 that supports the first slat group G1 in a suspended manner has a shape that allows the tilt shaft 4 to relatively rotate within a range of approximately 60 degrees. .

  Further, the insertion hole 24b of the worm 12 of the runner 3 that supports the second slat group G2 in a suspended manner has a shape that makes the tilt shaft 4 relatively unrotatable as shown in FIG. Other configurations are the same as those in the first embodiment.

  With such a configuration, the tilt shaft 4 is rotated by the operation of the operating rod from the state in which the first and second slat groups G1 and G2 pulled out along the hanger rail are rotated to the fully closed state. When the second slat group G1 and G2 are rotated, the first slat group G1 is rotated with a delay of 60 degrees with respect to the second slat group G2.

  Therefore, this embodiment can obtain the same effects as those of the first embodiment. Further, the first slat group G1 can be rotated by being delayed by 60 degrees with respect to the second slat group G2 at any position on the tilt axis 4.

You may implement the said embodiment in the following aspects.
-In 1st embodiment, the 1st axial part 16a and the 2nd axial part 16b are arbitrary, such as 1: 2 or 1: 3 other than the length which bisects the full length of the tilt axis | shaft 4. It may be the length of the ratio.
