(First embodiment)
As shown in FIGS. 1 and 2, a plurality of carriers 12 are arranged in a head rail 10 fixed to a window frame or the like (not shown) by a bracket 11 so as to be slidable in the longitudinal direction. The louver 14 is suspended from the hook via the hook 13.

  An end cap 18 having a pair of insertion holes 18a through which the opening / closing cord 16 is inserted is provided at one end of the head rail 10, and the opening / closing cord 16 is rotated at the other end of the head rail 10. A control box 20 having a roller 20a therein is provided.

  Among the plurality of carriers 12, the carrier at the end (left end in FIG. 1) is a master carrier 12A, and the opening / closing cord 16 that is arranged endlessly in the head rail 10 is arranged on the master carrier 12A. Both ends are connected.

  That is, one end of the opening / closing cord 16 is connected to the master carrier 12A in the head rail 10, and the other end of the opening / closing cord 16 is connected to the head rail 10 as shown in FIG. It is led out from one insertion hole 18a of the end cap 18 at one end and turned downward, wound around a guide part 34 described later, and turned again in the horizontal direction through the other insertion hole 18a of the end cap 18. It is introduced into the head rail 10. After being introduced into the head rail 10, the other end of the opening / closing cord 16 is inserted through an insertion hole (not shown) of the master carrier 12A and one insertion hole 12a of each carrier 12 shown in FIG. Then, it is turned downward by the roller 20a at the other end of the head rail 10, and as shown in FIG. 2C, it hangs down from the head rail 10, is folded back, and is introduced into the head rail 10 again. . The other end portion of the opening / closing cord 16 introduced into the head rail 10 is horizontally turned by the roller 20a and is inserted through the other insertion hole 12b of each carrier 12 as shown in FIG. 2 (b). To the master carrier 12A.

  A portion of the opening / closing cord 16 that hangs from the other end of the head rail 10 constitutes an opening / closing operation portion 16a, and the movement of the carrier 12 and the louver 14 can be externally operated by operating the opening / closing operation portion 16a. .

  A cover 18b covering the entire surface of the end cap 18 is attached to the side end portion of the end cap 18. The cover 18b covers the pair of insertion holes 18a and the opening / closing cord 16 led out from the pair of insertion holes 18a.

  One end of the head rail 10 is provided with an adjusting means 30 for adjusting the length of the opening / closing operation part 16a. The adjusting means 30 has a rectangular parallelepiped guide case 31 supported downwardly from the end cap 18 and, as shown in FIG. 2, a guide groove 32 extending in the vertical direction on one side surface of the guide case 31. In the middle of the guide groove 32 in the vertical direction, a plurality of locking portions 32a having a narrow groove width (three places in the example in the figure) are provided.

  A guide portion 34 is accommodated in the guide case 31 so as to be movable in the vertical direction. The guide portion 34 has a substantially columnar shape, and is slidably fitted in the guide groove 32 and slidable within the guide case 31. A winding portion 34b having a diameter larger than that of the portion 34a and winding the opening / closing cord 16 about a half turn; and a knob button-like adjustment operation portion 34d outside the guide case 31 and having a diameter larger than that of the sliding portion. And comprising.

  The axial dimension of the sliding part 34a is slightly larger than the width of the locking part 32a, and thereby the movement of the guide part 34 is restricted by coming into contact with the locking part 32a. It is possible to move over the locking portion 32a by applying force.

  The adjustment operation portion 34d has a larger shaft diameter than the width of the guide groove 32, and thus the adjustment operation portion 34d is prevented from entering the guide case 31 through the guide groove 32. In addition, although the guide part 34 was made into an integral component, it is not restricted to this, For example, the adjustment operation part 34d and another site | part may be comprised by another component.

  A drive gear mechanism (not shown) is built in the control box 20 at the other end of the head rail 10, and the drive gear mechanism is connected to a rotary rod 26 that is rotatably supported in the head rail 10. ing. The rotating rod 26 extends in the longitudinal direction of the rail in the head rail 10 and passes through each carrier 12 while meshing with a rotation transmission mechanism 12 c built in each carrier 12. An operating rod 28 is connected to the drive gear mechanism, and the operating rod 28 is suspended from the head rail 10. When the operation rod 28 is operated to transmit the rotation from the drive gear mechanism to the rotation rod 26, the hook 13 is rotated through the rotation transmission mechanism 12c of each carrier 12, and the louver 14 can be rotated. ing. Accordingly, the louver 14 is rotated in a state substantially parallel to the longitudinal direction of the rail of the head rail 10 as shown in FIG. 5 to close the louver 14, or the louver 14 is moved to the head rail 10 as shown in FIG. The louver 14 can be opened by rotating it in a state orthogonal to the rail longitudinal direction.

  In the vertical blind constructed as described above, the adjustment operation portion 34d is guided from the state in which the guide portion 34 is at the upper end position of the guide groove 32 as shown in FIGS. When operated so as to move downward along the groove 32a, the sliding portion 34a slides downward in the guide groove 32, and the opening / closing cord 16 wound around the winding portion 34b is replaced by the guide portion 34. Is pulled out from one end of the head rail 10 through a pair of insertion holes 18a of the end cap 18 and separated. The drawn opening / closing cord 16 is accommodated in the guide case 31 and is not exposed to the outside. When the sliding portion 34a of the guide portion 34 moves to the position of the locking portion 32a, the sliding portion 34a is locked to the locking portion 32a, but the adjusting operation portion resists the resistance force received from the locking portion 32a. When the slider 34d is further moved downward, the sliding portion 34a can get over the locking portion 32a. As shown in FIGS. 3, 4, and 5 (b), the sliding portion 34a is maximized and the guide groove 32 is moved. It is possible to slide to the lower end position.

  Thus, when the opening / closing cord 16 wound around the winding portion 34b is separated from the one end portion of the head rail 10, the opening / closing operation portion 16a hanging from the other end portion side of the head rail 10 is formed. The opening / closing cord 16 is pulled into the head rail 10 to shorten the length of the opening / closing operation portion 16a.

  The adjustment operation part 34d does not necessarily have to slide to the lower end of the guide groove 32. When the sliding part 34a gets over the locking part 32a at a desired position, the adjustment operation part 34d is operated downward or upward. By stopping the movement, the guide portion 34 can be locked to the desired locking portion 32a and its movement can be restricted. Accordingly, the length of the opening / closing cord 16 constituting the opening / closing operation portion 16a drawn into the head rail 10 can be changed depending on the position of the locking portion 32a for locking the guide portion 34, and the opening / closing operation portion 16a. Can be easily adjusted to a desired length suitable as an operation unit.

  The above operation of the guide unit 34 is performed once in order to set the opening / closing operation unit 16a to a desired length at the time of initial setting of the vertical blind, and thereafter, unless there is a special request for changing the desired length, the guide unit 34 is operated. Although the position of the part 34 can be used as fixed, it is also conceivable to operate the guide part 34 every time the opening / closing operation part 16a is operated. In the former case, it is preferable that the locking force by the locking portion 32a is greater than the force acting on the opening / closing cord 16 during the opening / closing operation of the vertical blind. In the latter case, when the louver 14 of the vertical blind is not operated, the guide portion 34 is operated so that the length of the opening / closing operation portion 16a is shortened. Prevent things, people and animals from getting caught. Further, when the louver 14 is operated, the adjustment operation unit 34d is operated to move upward along the guide groove 32, or the opening / closing operation unit 16a is directly pulled downward. Then, the sliding portion 34a gets over the locking portion 32a, and slides the sliding portion 34a up to the upper end position of the guide groove 32 as shown in FIGS. 1, 2A, and 5A. Can be made. When the opening / closing cord 16 wound on the winding portion 34b approaches the one end portion of the head rail 10, the opening / closing cord constituting the opening / closing operation portion 16a hanging from the other end side of the head rail 10 is thus obtained. As shown in FIGS. 1 and 2 (c), 16 is pulled out from the head rail 10 to increase its length. This makes it easy to operate.

  In this way, by moving the adjustment operation part 34d in the vertical direction, the length of the opening / closing operation part 16a can be adjusted to an arbitrary length, so that the adjustment work can be easily performed. Alternatively, it is easy to use when operating the vertical blind louver, and when the louver is not operated, the length of the safe opening / closing operation section 16a can be obtained.
