  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The vertical blind of the present invention has a head rail 10 that is fixed to a window frame, a wall surface, or the like by a bracket (not shown), and is slidable in the head rail 10 in the longitudinal direction as shown in FIG. A plurality of carriers 12 are arranged, and a louver 14 is suspended from each carrier 12 via a hook 13 as shown in FIG.

  Each carrier 12 is connected to and adjacent to the adjacent carrier 12 by a spacer member so that the predetermined interval is the maximum interval. The carrier at the end (left end in FIG. 1) among the plurality of carriers 12 is a master carrier 12A, and the opening / closing cord distributed endlessly in the head rail 10 to the master carrier 12A. 16 are connected.

  A part of the opening / closing cord 16 is suspended from one cord guide 18 provided at both ends of the head rail 10 to constitute an operation portion 16a that can be operated externally. Further, one end 16b of the opening / closing cord 16 is inserted into the insertion hole 12c formed in each carrier 12 in the head rail 10, and is locked to the connection hole 12f of the master carrier 12A. The other end 16c of the opening / closing cord 16 is inserted through the insertion hole 12d formed in each carrier 12 in the head rail 10 and through the insertion hole 12e of the master carrier 12A. It is folded and locked in the communication hole 12g of the master carrier 12A.

  As shown in FIGS. 4 to 8, the cord guides 18 provided at both ends of the head rail 10 are used to turn the opening / closing cord 16 and to turn the opening / closing cord 16 from the head rail 10. And a derivation unit 18b. The turning portion 18a forms a substantially semicircular guide path in the horizontal plane so that the opening / closing cord 16 can be folded back, and the lead-out portion 18b allows the opening / closing cord 16 to hang from the head rail 10. Before and after the head rail 10, a pair of arc-shaped guide paths are formed on a vertical plane that leads from the inside of the head rail 10 to the lower portion of the head rail 10. The end portion side of the turning portion 18a is open, and this open portion is connected to the lead-out portion 18b, so that this portion allows the opening / closing cord 16 to pass between the turning portion 18a and the lead-out portion 18b. A freely communicating portion 18c is configured.

  Preferably, a cover 19 is detachably attached to the end of the code guide 18. Locking claws 19a protrude from the upper corners of the cover 19, and fitting protrusions 19b and 19b protrude from the lower corners, respectively. On the code guide 18 side, a locking hole 18h is provided at a position corresponding to the locking claw 19a, and a fitting hole 18i is provided at a position corresponding to the fitting protrusion 19b.

  The turning portion 18a and the lead-out portion 18b are connected to each other by the communication portion 18c described above, and the opening / closing cord 16 distributed by the turning portion 18a is further connected to the lead-out portion 18b via the communication portion 18c. It can be pulled out of the rail. The cover 19 may be removed when the opening / closing code 16 is pulled out from the cord guide 18.

  In the example shown in FIGS. 4 to 8, the communication portion 18c can be opened and the opening / closing cord 16 can be pulled out even when the cover 19 is attached. Instead, as shown in FIGS. 17 to 19, the communication portion 18 c may be completely closed with the cover 19 attached. For this reason, in the example of FIGS. 17 to 19, the portion 18 j located below the turning portion 18 a and between the pair of guide paths of the lead-out portion 18 b protrudes in the direction of the cover 19, and the cover 19 is removed. In this state, the communication part 18c is completely closed. By configuring in this way, it is possible to prevent the opening / closing cord 16 from moving to the communicating portion 18c and moving in the wrong direction during normal times when the cover 19 is attached.

  Or, optionally, the cover 19 may not be provided at all, and the turning part 18a, the lead-out part 18b, and the communication part 18c may be exposed.

  The code guide 18 incorporates a drive gear mechanism 22 (see FIG. 9). The drive gear mechanism 22 is coupled to a rotating rod 23 that is rotatably supported in the head rail 10. The rotating rod 23 extends in the longitudinal direction of the rail in the head rail 10, and passes through each carrier 12 while engaging with a rotation transmission mechanism built in each carrier 12. An operation rod 20 can be detachably connected to the drive gear mechanism 22. When the operating rod 20 is connected to the drive gear mechanism 22, it is suspended from the code guide 18. When the operation rod 20 is operated to transmit the rotation from the drive gear mechanism 22 to the rotation rod 23, the hook 13 rotates via the rotation transmission mechanism of each carrier 12, and the louver 14 can be rotated. ing.

  In the example shown in FIG. 1 and FIG. 9, the opening / closing cord 16 is led out from the lead-out portion 18 b of the cord guide 18 at the right end portion of the head rail 10 in the figure and is suspended from the right end portion of the head rail 10 for operation. The turning part 18a of the cord guide 18 which comprises the part 16a and is located in the left end part in the figure of the head rail 10 is turned, accommodated in the left end part of the head rail 10, and turned up at the left end part. Further, the operating rod 20 is connected to the drive gear mechanism 22 of the cord guide 18 at the right end of the head rail 10 in the drawing so as to match the position of the operating portion 16a.

  The operation of the vertical blind constructed as described above will be described. As shown in FIG. 9, when one of the operation portions 16a 16a1 (see FIG. 1) is pulled down from the state in which the louver 14 is unfolded, one end 16b of the opening / closing cord 16 shows the master carrier 12A in the drawing as shown in FIG. Pulling rightward, the master carrier 12A moves rightward in the figure. Then, since the master carrier 12A sequentially pushes out the other carriers 12 in the same direction, the louver 14 moves, and as shown in FIGS. 1 and 11, toward the right end portion of the head rail 10 in the drawing. It is in a folded state.

  When the louver 14 is deployed from the state shown in FIG. 11, when the other 16a2 (see FIG. 1) of the operation portion 16a is pulled down, the other end 16c of the opening / closing cord 16 causes the master carrier 12A to move to the left in FIG. The master carrier 12A moves to the left in the figure. Then, since the master carrier 12A sequentially pulls the other carriers 12 through the spacer member in the same direction, the louver 14 moves and is in a developed state as shown in FIG.

  Next, when it is desired that the position of the operation portion 16a and the operation rod 20 be set to the left end portion instead of the right end portion in the figure of the head rail 10, first, the cover 19 of the code guide 18 at the left end portion in the figure is first attached. With the cover 19 attached or removed (if necessary, the cover 19 of the cord guide 18 at the right end is also removed) and pulled out by the turned portion 18a of the opening / closing cord 16. As a result, the opening / closing cord 16 that is partially suspended from the right end in FIG. 12 passes through the insertion hole 12d of each carrier 12 and the insertion hole 12e of the master carrier 12A, and the cord guide at the left end in FIG. As shown in FIG. 6, it is led out to 18 through the communication part 18c to the lead-out part 18b and led out from the code guide 18 to become the operation part 16a. On the other hand, in the cord guide 18 at the right end in FIG. 12, as shown in FIG. 5, the opening / closing cord 16 is guided and accommodated to the turning portion 18a via the communication portion 18c. Thereafter, a cover 19 is attached to the code guide 18. Further, the operation rod 20 connected to the drive gear mechanism 22 of the cord guide 18 at the right end in FIG. 12 is removed and reconnected to the drive gear mechanism 22 of the code guide 18 at the left end in FIG. The portion 16a and the operation rod 20 can be moved from the right end portion in FIG. 12 of the head rail 10 to the left end portion, and the operation position can be switched between right and left.

  When the louver 14 is folded by operating the operating portion 16a moved to the left end portion of the head rail 10 in FIG. 12, when one 16a1 (see FIG. 2) of the operating portion 16a is pulled down, one end 16b of the opening / closing cord 16 is moved. The master carrier 12A is pulled to the right in FIGS. 2 and 13, and the master carrier 12A moves to the right in the drawing. Then, since the master carrier 12A sequentially pushes out the other carriers 12 in the same direction, the louver 14 moves to the right as shown in FIG. 13, and the head rail 10 moves toward the right end in FIG. It will be folded.

  Thus, even if the left and right positions of the operation unit 16a are switched, the folding direction of the louver 14 is the same.

  On the other hand, when the folded louver 14 is expanded, the other 16a2 (see FIG. 2) of the operation unit 16a is pulled down. Thereby, the other end 16c of the opening / closing cord 16 pulls the master carrier 12A leftward in FIGS. 2 and 13, and the master carrier 12A moves leftward in the figure. Then, since the master carrier 12A sequentially pulls the other carriers 12 in the same direction, the louver 14 moves and becomes in a developed state as shown in FIG.

  As described above, in the example shown in FIGS. 2 and 12 to 13, only the position of the operation unit can be changed without changing the convolution direction. Since this change can be performed while the head rail 10 is fixed, the operation is simple and can be easily performed.

  On the other hand, in order to change the folding direction of the louver 14 without changing the position of the operation unit, the entire vertical blind as shown in FIGS. 3 and 14 is moved from the state shown in FIGS. 2 and 12 to 13 to the left and right. It can be performed by reversing and fixing it to a window frame, a wall surface or the like with a bracket not shown. As a result, the operation portion 16a and the operation rod 20 move to the right end portion of the head rail 10 in the figure, and the master carrier 12A is positioned at the right end portion of the carrier 12 row.

  In this way, when the entire vertical blind is reversed and fixed, when the louver 14 is folded, one side 16a1 (see FIG. 3) of the operation unit 16a is pulled down. Thereby, the one end 16b of the opening / closing cord 16 pulls the master carrier 12A leftward in FIGS. 3 and 15, and the master carrier 12A moves leftward in the figure. Then, since the master carrier 12A sequentially pushes the other carriers 12 in the same direction, the louver 14 moves and is folded to the left end side in the drawing of the head rail 10 as shown in FIG. It becomes a state. In this way, the convolution direction can be changed.

  When unfolding the louver 14 from the folded state as shown in FIG. 16, the other 16a2 (see FIG. 3) of the operation portion 16a is pulled down. As a result, the other end 16c of the opening / closing cord 16 pulls the master carrier 12A rightward in FIGS. 3 and 15, and the master carrier 12A moves rightward in the figure. Then, since the master carrier 12A sequentially pulls the other carriers 12 in the same direction, the louver 14 moves in the right direction in the figure, and is in a developed state as shown in FIG.

  As described above, the opening / closing cord 16 routed in the head rail 10 can be pulled out from both the left and right ends of the head rail 10, and the operating portion 16 a is configured by the drawn opening / closing cord 16. Thus, the position of the operation unit can be changed only by changing the drawing side of the opening / closing cord 16. Thus, the position of the operation unit can be easily changed. Moreover, the folding direction of the louver 14 can be changed by reversing the head rail 10 left and right. Therefore, the installation direction of the louver 14 or the position of the operation unit 16a can be easily changed without disassembling or reassembling the parts at the installation site or in the existing setting state. it can.

  In addition, the cord guides 18 having the same shape including the turning portions 18a and the lead-out portions 18b for guiding the folding and derivation of the opening / closing cords 16 are provided at both ends of the head rail 10, so that the opening / closing cords 16 are smoothly arranged. While being rotated, the components at both ends of the head rail 10 can be shared.

  Further, since the drive gear mechanism 22 is built in the code guide 18 and the drive gear mechanism 22 and the operation rod 20 are detachable, the position of the operation rod 20 is also changed in accordance with the change in the position of the operation portion 16a. can do.
