Further, if the first lifting / lowering cord 10 is pulled into the head box 1 based on the weight of the intermediate rail 3, the intermediate rail 3 is lowered and returned to the state supported by the ladder cord 8 from the upper slat 9. .

  The stopper 11 prevents the weight of the intermediate rail 3 from dropping when the first operation cord 13 is not operated. Further, the length of the first lifting / lowering cord 10 is set so that when the intermediate rail 3 is lowered to the lowest limit, the cord equalizer 12 rises to a position where it abuts against the stopper 11.

  In the slat 9, a second elevating cord 14 for elevating the pleat curtain 4 is inserted in parallel with the first elevating cord 10 inserted in both side portions of the slat 9. One end of the second lifting / lowering cord 14 is inserted through the intermediate rail 3 and the curtain fabric 15 of the pleated curtain 4 and connected to the bottom rail 16.

The other end of the second lifting / lowering cord 14 is attached to the winding pipe 6 in the head box 1.
A curtain elevating shaft 17 is inserted into the winding pipe 6, and a slat angle adjusting shaft 18 is inserted into the ladder cord support device 7. One end of the curtain lifting / lowering shaft 17 and the slat angle adjusting shaft 18 is connected to a gear box 19 provided at one end of the head box 1.

  A pulley 20 is rotatably supported at one end of the gear box 19, and a second operation cord 21 hung on the pulley 20 is suspended downward from one end of the head box 1. The curtain elevating shaft 17 and the slat angle adjusting shaft 18 are rotated through the gear box 19 by the operation of the second operation cord 21.

  When the curtain lifting / lowering shaft 17 is rotated, the second lifting / lowering cord 14 is wound or unwound on the winding pipe 6, and the bottom rail 16 is lifted / lowered. The dough 15 is raised and lowered.

  When the slat angle adjusting shaft 18 is rotated, each slat 9 is rotated in the same phase via the ladder cord support device 7 and the ladder cord 8. Further, when each slat 9 is rotated to a substantially vertical direction, the slat angle adjusting shaft 18 is idle with respect to the ladder cord support device 7 so that each slat 9 is not further rotated in the same direction. .

  The gear box 19 has a speed reducing function for decelerating the rotation of the pulley 20 and transmitting it to the curtain elevating shaft 17 and the slat angle adjusting shaft 18, and a function for preventing the intermediate rail 3 and the slat 9 from falling by its own weight. .

  As shown in FIG. 3, the curtain elevating shaft 17 is attached to a plate-like fabric retainer 22, and the fabric retainer 22 is detachably attached to the intermediate rail 3. The lower end of the first lifting / lowering cord 10 is attached to the center of the intermediate rail 3 in the front-rear direction (left-right direction in FIG. 3), and the intermediate rail 3 is balanced by the first lifting / lowering cord 10 in a substantially horizontal direction. It is supported by suspension.

  A lower end portion of the ladder cord 8 is attached to an attachment member 23 having the same shape as the fabric presser 22, and the attachment member 23 is detachably attached to the intermediate rail 3. The length of the ladder cord 8 is such that a slack (maintenance means) 8a occurs in the warp of the ladder cord 8 between the lowermost slat 9 and the intermediate rail 3 in a state where the intermediate rail 3 is lowered to the lowest limit. Is set.

  As shown in FIG. 2, a pitch holding cord 24 for maintaining the folds of the curtain fabric 15 at equal intervals is connected to the back side of the curtain fabric 15 of the pleated curtain 4. The pitch holding cord 24 is connected to the folded portion of the curtain fabric 15 every two steps at equal intervals, and has an upper end connected to the fabric presser 22 and a lower end connected to the bottom rail 16.

  As shown in FIG. 3, the mounting position of the pitch holding cord 24 with respect to the fabric presser 22 is the rear side of the fabric presser 22, and the hanging position of the curtain fabric 15 is the front side of the fabric presser 22. The mounting position of the pitch holding cord 24 and the hanging position of the curtain fabric 15 are located at an equal distance from the center of the intermediate rail 3 in the front-rear direction.

  Accordingly, when the curtain fabric 15 is lowered to the lower limit and the pitch holding cord 24 is tensioned, a load is applied to the front and rear portions of the fabric retainer 22, and the intermediate rail 3 is maintained in the horizontal direction. Yes.

  The support member 5 has a lower limit detection that prevents unwinding of the second lifting / lowering cord 14 from the winding pipe 6 when the looseness of the second lifting / lowering cord 14 is detected below the winding pipe 6. A device 25 is provided.

This lower limit detection device 25 is a known device including a ratchet mechanism that operates to prevent the winding pipe 6 from rotating when the slack of the second lifting / lowering cord 14 is detected.
And, when the second lifting / lowering cord 14 is further rewound from the state where the bottom rail 16 is lowered to the lowest limit, that is, the state where the pitch holding cord 24 is tensioned, the second lifting / lowering cord 14 is slackened. The lower limit detection device 25 operates to detect this slack and prevent the winding pipe 6 from rotating further.

In addition, when the lower limit detection apparatus 25 operates, it sets so that the 2nd raising / lowering cord 14 may be left to wind around the winding pipe 6 for 2 to 3 rounds.
Next, the operation of the solar radiation shielding device configured as described above will be described. When the first operating cord 13 is operated to pull out the first lifting / lowering cord 10 from the stopper 11, the intermediate rail 3 is pulled up and each slat 9 is pulled up. When the first lifting / lowering cord 10 is pulled into the head box 1 from the stopper 11, the intermediate rail 3 is lowered and each slat 9 is lowered.

  When the code equalizer 12 abuts against the stopper 11 during the lowering operation of the slat 9, further lowering of the intermediate rail 3 is prevented, and the intermediate rail 3 is lowered to the lowest position.

At this time, as shown in FIG. 3, the ladder cord 8 between the lowermost slat 9 and the intermediate rail 3 is in a state in which a slack 8a is generated.
When the second operation cord 21 is operated, the slat 9 is rotated, the bottom rail 16 is raised and lowered, and the pleated curtain 4 suspended from the intermediate rail 3 is raised and lowered.

  When the second lifting / lowering cord 14 is further rewound from the winding pipe 6 from the state where the bottom rail 16 is lowered until the pitch holding cord 24 is tensioned, the second lifting / lowering cord 14 is slackened.

Then, the lower limit detection device 25 is operated, the rotation of the winding pipe 6 is prevented, and the further rewinding of the second lifting / lowering cord 14 is prevented.
At this time, since the second lifting / lowering cord 14 is wound around the winding pipe 6 by two to three turns, the subsequent lifting operation of the bottom rail 16 can be performed smoothly.

  Even if the angle of the slat 9 is adjusted from the state in which the intermediate rail 3 is lowered to the lowest limit, and the slat 9 is rotated in the vertical direction, the tension of the ladder cord 8 is reduced by the slack 8a of the ladder cord 8. Is not communicated to. Therefore, as shown in FIG. 4, the intermediate rail 3 is always maintained in the horizontal direction.

In the solar shading device configured as described above, the following operational effects can be obtained.
(1) When the angle of the slat 9 of the horizontal blind 2 is adjusted, the intermediate rail 3 is not rotated. Therefore, the intermediate rail 3 can always be maintained in the horizontal direction.
(2) Since the intermediate rail 3 can always be maintained in the horizontal direction, exposure of the lower surface of the intermediate rail 3 to the indoor side can be prevented. Therefore, since the attachment part of the curtain raising / lowering shaft 17 is not exposed, aesthetics can be improved.
(3) Since the intermediate rail 3 can always be maintained in the horizontal direction, exposure of the lower surface of the intermediate rail 3 to the indoor side can be prevented. Therefore, since the cloth presser 22 for attaching the curtain lifting shaft 17 to the intermediate rail 3 is not exposed to the indoor side, the aesthetic appearance can be improved.
(4) The lower limit position of the intermediate rail 3 can be set by bringing the cord equalizer 12 into contact with the stopper 11. Therefore, the length of the slack 8a portion of the ladder cord 8 can be adjusted by adjusting the attachment position of the cord equalizer 12 with respect to the first lifting cord 10.
(5) By detecting the slack of the second lifting / lowering cord 14 by the lower limit detecting device 25, it is detected that the bottom rail 16 has been lowered to the lowest limit, and the second lifting / lowering cord 14 is further rewound. Can be prevented.
(6) When the bottom rail 16 is lowered to the lowest limit, the load acts on both sides of the fabric retainer 22 in the front-rear direction, so that the intermediate rail 3 can be stably held in the horizontal direction.
(7) Since the lower end of the ladder cord 8 is attached to the attachment member 23 and the attachment member 23 is attached to the intermediate rail 3, the length of the slack 8a is adjusted by removing the attachment member 23 from the intermediate rail 3. In addition, the ladder cord 8 can be easily attached to the intermediate rail 3.

You may implement the said embodiment in the following aspects.
The lower end of the ladder cord 8 may be directly connected to the intermediate rail 3.
