(First embodiment)
A first embodiment embodying the present invention will be described below with reference to FIGS. In the horizontal blind shown in FIGS. 1 and 2, a multi-stage slat 13 and a bottom rail 14 are suspended and supported from a head box 11 via a plurality of ladder cords 12.

  In the slats 13, elevating cords 15 are inserted in the vicinity of the positions where the ladder cords 12 are supported. The lifting cord 15 is attached to the head box 11 at one end, is hooked on a pulley 16 that passes through the slat 13 and is rotatably supported in the bottom rail 14, and the ladder cord 12 extends from the pulley 16. In the vicinity of the support position, the slats 13 are passed through the guide rollers 17 in the head box 11.

  The lifting / lowering cord 15 hung on the guide roller 17 is guided in the head box 11 to one end side of the head box 11 and is suspended from the head box 11 through the stopper device 18.

  An operation cord 20 is connected to lower ends of a plurality of lifting cords 15 suspended from the stopper device 18 via a cord equalizer (regulating means) 19. Then, by operating the operation cord 20 and pulling the lifting / lowering cord 15 from the stopper device 18, the bottom rail 14 is pulled up, and the lower slat 13 is sequentially stacked on the bottom rail 14 and pulled up.

  Further, if the lifting / lowering cord 15 is drawn into the head box 11 through the stopper device 18 based on the weight of the bottom rail 14, the bottom rail 14 is lowered and each slat 13 is supported by the ladder cord 12. Return.

The stopper device 18 has a known configuration that prevents the lifting / lowering cord 15 from being pulled in to prevent the bottom rail 14 from dropping its own weight when the operation cord 20 is released.
An operating rod 21 is suspended from one end of the head box 11. When the operation rod 21 is rotated, the angle adjustment shaft 22 is rotated through a gear box (not shown) in the head box 11, and the rotation of the angle adjustment shaft 22 causes the ladder cord support device 23 and the ladder cord 12 to move. Thus, each slat 13 is rotated in the same phase.

  A lower end portion of the operation cord 20 is supported by a cord holding device 24 provided on the bottom rail 14. As shown in FIG. 2, the cord holding device 24 includes a pair of support pieces 25 a and 25 b that are attached at the base end to the bottom rail 14 and extend forward from the bottom rail 14, that is, toward the indoor side. ing.

  A guide roller (first guide portion) 26 is rotatably supported between the tip portions of the support pieces 25a and 25b, and the operation code 20 is interposed between the guide roller 26 and the guide roller 26. A guide piece (second guide portion, restricting means) 27 is provided with an interval through which the can be inserted.

  A guide shaft 28 is provided at a position obliquely below the guide roller 26 between the guide roller 26 and the bottom rail 14. The operation cord 20 is guided downward from between the guide piece 27 and the guide roller 26 through the guide roller 26 and the guide shaft 28, and the end of the operation cord 20 is attached to the bottom rail 14. A first endless edge is generated in the operation cord 20 below the guide shaft 28.

  A pulley 29 is hung on the first endless edge of the operation cord 20, and a weight 30 is suspended from the pulley 29. Accordingly, the first endless edge of the operation cord 20 is always urged downward.

  In the cord holding device 24 configured as described above, when the bottom rail 14 is lowered to the lower limit as shown in FIG. 2, the pulley 29 is suspended in the vicinity of the guide shaft 28 so that the operation cord 20 is suspended. The length is set.

  When the operation cord 20 is pulled downward from this state and the lifting / lowering cord 15 is pulled out from the head box 11, the operation cord 20 is loosened in front of the guide roller 26 as shown in FIG. Then, as shown in FIG. 4, the pulley 29 is lowered by the weight of the weight 30, and the slack of the operation cord 20 in front of the guide roller 26 is absorbed.

  When the lifting / lowering cord 15 is further pulled out from the head box 11, as shown in FIG. 5, the code equalizer 19 comes into contact with the guide roller 26 and the pulley 29 is prevented from further descending.

If the lifting / lowering cord 15 is further pulled downward from this state, the length of the second endless edge of the lifting / lowering cord 15 that hangs downward from the cord equalizer 19 increases as shown in FIG.
The operation of the cord holding device 24 that performs the above operation will be described with reference to FIGS. FIG. 6 shows a state where the bottom rail 14 is lowered to the lower limit. Here, if the height of the product is H, the length of the lifting / lowering cord 15 is set to about 2H, the length of the operation cord 20 is set to about H, and the code equalizer 19 is located in the vicinity of the head box 11. Further, the pulley 29 is suspended near the bottom rail 14.

  In such a horizontal blind, the pulley 16 provided on the bottom rail 14 operates as a moving pulley. Therefore, when the bottom rail 14 is pulled up by the lifting distance a, it is necessary to pull out the lifting / lowering cord 15 by a length of 2a.

  When the operation cord 20 is pulled downward from the state shown in FIG. 6 and the bottom rail 14 is pulled up, the pulley 29 descends. When the bottom rail 14 is pulled up at a height of H / 3, as shown in FIG. 7, the lifting / lowering cord 15 is pulled out by a length of 2H / 3, and the distance between the guide roller 26 and the pulley 29 is H / 2. Become. At this time, the code equalizer 19 is lowered to a position where it abuts on the guide roller 26. Further, when the floor surface F is in the vicinity of the lower limit position of the bottom rail 14, the operation cord 20 corresponding to the height of H / 6 from the pulley 29 hangs on the floor surface F.

  When the lifting / lowering cord 15 is further lowered from the state shown in FIG. 7 and the bottom rail 14 is pulled up from the lower limit position to the height of H / 2 as shown in FIG. 8, the pull-out length of the lifting / lowering cord 15 becomes H, and the pulley 29 is in a state of being suspended and supported at substantially the height of the floor surface F. In addition, the lifting / lowering cord 15 hangs in front of the guide roller 26, and the lower edge thereof is approximately 5H / 6 from the head box 11. Therefore, in this state, the operation cord 20 and the lifting / lowering cord 15 do not crawl on the floor surface F.

  When the bottom rail 14 is pulled up to the upper limit, as shown in FIG. 9, the pulling length of the lifting / lowering cord 15 becomes approximately 2H, and the pulley 29 is suspended and supported from the guide roller 26 at a height of H / 2. The distance between the lower end of the lifting / lowering cord 15 that is suspended and supported in front of the bottom rail 14 is about H. Therefore, even in this state, the operation cord 20 and the lifting / lowering cord 15 do not crawl on the floor surface F.

  When the lifting / lowering cord 15 is pulled into the head box 11 from the state where the bottom rail 14 is pulled up to the upper limit, the bottom rail 14 is lowered to the lower limit position shown in FIG. 6 through the state shown in FIGS.

In the horizontal blind slat lifting apparatus configured as described above, the following operational effects can be obtained.
(1) By pulling the lifting / lowering cord 15 from the head box 11 or pulling the lifting / lowering cord 15 into the head box 11, the bottom rail 14 can be raised and lowered to raise and lower the slat 13.
(2) Since the pulley 16 provided on the bottom rail 14 can be operated as a moving pulley, the operation force required for the lifting operation of the bottom rail 14 can be reduced.
(3) When the bottom rail 14 is pulled up to a height equal to or higher than H / 2 with respect to the product height H, the length of the operation cord 20 hanging from the guide roller 17 can be set to H / 2 or less. Therefore, even when the lower limit position of the bottom rail 14 is in the vicinity of the floor surface F, the operation cord 20 is prevented from getting on the floor surface F when the bottom rail 14 is pulled up to a height of H / 2 or higher. Can do.

FIG. 10 shows a second embodiment. In this embodiment, a cord holding device is provided on a pleated screen having an intermediate rail.

  In the pleated screen shown in FIG. 10, a head box 31 is fixed to a mounting surface 33 via a mounting bracket 32, and an upper screen 34 is suspended and supported from the head box 31.

  The upper screen 34 is provided with joining pieces 35 at both upper and lower edges of the fabric having a fold 36 in the middle in the vertical direction, and another joining piece 35 of the other fabric is joined to the joining piece 35 by means such as welding. Thus, it can be bent in a zigzag shape in the vertical direction.

  A first lifting / lowering cord (not shown) suspended from the head box 31 is inserted into the joining piece 35 of the upper screen 34, and the upper end of the first lifting / lowering cord is operated by the lifting / lowering cord in the head box 31. Supported by the apparatus, the lower end is attached to the intermediate rail 37. And by operating the 1st raising / lowering cord, the intermediate rail 37 can be raised / lowered and the upper screen 34 can be raised / lowered.

  A lower screen 38 is suspended and supported from the intermediate rail 37. The lower screen 38 is formed of the same material as that of the upper screen 34, for example, with a material having a higher light shielding property than the upper screen 34.

  A second lifting / lowering cord 39 is suspended and supported from the head box 31 at a position different from the hanging position of the first lifting / lowering cord, and the second lifting / lowering cord 39 is inserted into the joining piece 35 of the upper screen 34, It is inserted through the intermediate rail 37 and through the joining piece 40 of the lower screen 38. The bottom rail 41 is suspended and supported at the lower end of the second lifting / lowering cord 39.

  A pair of pulleys 42 a and 42 b are rotatably supported at the rear portion in the intermediate rail 37 at the insertion position of the second lifting / lowering cord 39. The second lifting / lowering cord 39 is inserted into the intermediate rail 37 while being sandwiched between the pulleys 42a and 42b.

  A first pitch holding cord 43 is suspended from the head box 31 behind the upper screen 34, and a second pitch holding cord 44 is suspended from the intermediate rail 37 behind the lower screen 38. Yes.

  When the intermediate rail 37 is lowered and the upper screen 34 is stretched, the folds 36 of the upper screen 34 are held at equal intervals by the first pitch holding cord 43. When the bottom rail 41 is lowered and the lower screen 38 is extended, the folds 36 of the lower screen 38 are held at equal intervals by the second pitch holding cord 44.

  The second lifting / lowering cord 39 is guided to one side in the head box 31 and is suspended downward from one end of the head box 31 via a stopper device (not shown). An operation cord 46 is connected to the lower end portion of the second lifting / lowering cord 39 via a cord equalizer 45.

  The operation cord 46 is hooked on a guide roller 47 provided at the tip of the intermediate rail 37, and the end of the operation cord 46 is attached to the intermediate rail 37. A pulley 48 is mounted on the operation cord 46 between the guide roller 47 and the intermediate rail 37, and a weight 49 is suspended and supported on the pulley 48.

  In the pleated screen as described above, the intermediate screen 37 can be lifted and lowered by operating the first lifting / lowering cord, and the upper screen 34 can be stretched and folded. When the second lifting / lowering cord 39 is pulled out from the head box 31, the bottom rail 41 can be pulled up and the lower screen 38 can be folded upward. The bottom rail 41 pushes up the intermediate rail 37 together with the lower screen 38 to fold the upper screen 34. You can also Further, when the second lifting / lowering cord 39 is pulled into the head box 31, the bottom rail 41 is lowered and the lower screen 38 can be extended.

  During the raising / lowering operation of the bottom rail 41, the second raising / lowering cord 39 and the operation cord 46 are formed with two endless edges between the head box 31 and the intermediate rail 37 by the guide roller 47 and the pulley 48. Therefore, the length of the operation cord 46 and the second lifting / lowering cord 39 hanging from the intermediate rail 37 can be shortened.

Therefore, even if the product height is increased and the pull-out length of the second lifting / lowering cord 39 is increased, the operation cord 46 and the second lifting / lowering cord 39 can be prevented from being caught on the floor surface.
11 and 12 show a pleated screen provided with a pulley that operates as a moving pulley on the bottom rail so as to reduce the operating force required for the lifting and lowering operation of the screen.

  In this pleated screen, a screen 51 similar to the upper screen 34 or the lower screen 38 of the pleated screen shown in FIG. 10 is suspended from a head box 52 and a bottom rail 53 is attached to the lower end of the screen 51.

  As shown in FIG. 11, a plurality of lifting cords 54 for lifting and lowering the screen 51 are attached to the head box 52 at one end, penetrate the joint piece 55 of the screen 51 and the bottom rail 53. It is hung on the pulleys 56a and 56b, and again passes through the joining piece 55 and is guided into the head box 52.

  The lifting / lowering cord 54 guided into the head box 52 is guided to one end of the head box 52 and supported by being suspended from the head box 52 via a stopper device (not shown). An operation cord 58 is suspended and supported through an equalizer 57.

  Of the lifting / lowering cord 54, a portion positioned between one end attached to the head box 52 and the bottom rail 53 is denoted by p1, and a portion guided to the head box 52 from the bottom rail 53 is denoted by p2. A pitch holding cord 59 is suspended from the head box 52 in the vicinity of the lifting cord p1.

  The pitch holding cord 59 is provided with annular support cords 60 at equal intervals, and the lifting cord p1 is inserted into the support cord 60 in a state where the support cords 60 are positioned below the joining pieces 55 every other stage. Yes.

  Accordingly, when the bottom rail 53 is lowered and the screen 51 is pulled down, every other joining piece 55 is supported by the support cord 60, and the folds 61 of the screen 51 are held at substantially equal intervals, as shown in FIG. It is like that.

  In the pleated screen configured as described above, when the operation cord 58 is pulled downward and the lifting / lowering cord 54 is pulled out from the head box 52, the bottom rail 53 is pulled up and the screen 51 is pulled up.

When the lifting / lowering cord 54 is pulled into the head box 52, the bottom rail 53 is lowered and the screen 51 is pulled down.
At this time, since the lifting / lowering cord 54 is hooked on the pulleys 56a and 56b of the bottom rail 53, the pulleys 56a and 56b act as moving pulleys, so that it is possible to reduce the operating force during such lifting and lowering operations. it can.

  During the raising / lowering operation of the bottom rail 53, the lifting / lowering cord p1 does not move in the vertical direction, and the lifting / lowering cord p2 moves in the vertical direction. Since the lifting / lowering cord p <b> 1 is inserted through the support cord 60 of the pitch holding cord 59, no friction is generated between the lifting / lowering cord p <b> 1 and the supporting cord 60.

  If the lifting / lowering cord p <b> 2 is inserted into the support cord 60, the lifting / lowering cord p <b> 2 moves in the up / down direction when the bottom rail 53 is lifted / lowered. In particular, when the bottom rail 53 is lowered, the lifting / lowering cord p2 moves downward, so that the friction between the support cord 60 that supports the joining piece 55 and the lifting / lowering cord p2 increases, and the bottom rail 53 becomes difficult to lower. Alternatively, the lifting / lowering cord p2 may be caught by the support cord 60 and cannot be lowered.

  In order to solve such a problem, it is necessary to increase the weight of the bottom rail 53. However, if the bottom rail 53 is increased, an operation force required for a lifting operation of the bottom rail 53 is increased.

Therefore, by inserting the lifting / lowering cord p1 through the support cord 60, the above-described problems can be solved.
In FIG. 13 and FIG. 14, the end of the lifting / lowering cord 54 suspended from the head box 52 is attached to the head box 52, and a pulley 62 is hung on the endless edge of the lifting / lowering cord 54. The lifting / lowering cord 54 can be pulled out from the head box 52 by pulling the pulley 62 downward via the operation cord 63, and the lifting / lowering cord 54 is pulled into the head box 52 by moving the pulley 62 upward. It is possible. Other configurations are the same as the configurations shown in FIGS. 12 and 13.

  With such a configuration, the pulling operation of the lifting / lowering cord 54 from the head box 52 can be performed via the pulley 62 acting as a moving pulley. Further, since the lifting / lowering cord p <b> 1 does not move in the vertical direction during the lifting / lowering operation of the screen 51, no friction is generated between the lifting / lowering cord p <b> 1 and the support cord 60. Since the lifting / lowering cord 54 is pulled out via the pulley 62, the lifting / lowering cord 54 having a length twice as long as the moving distance of the pulley 62 can be pulled out. Therefore, by placing the pulley 62 in the vicinity of the head box 52 with the bottom rail 53 lowered to the lower limit, it is possible to shorten the length of the lifting / lowering cord 54.

You may implement the said embodiment in the following aspects.
In the first embodiment, when pulling the lifting / lowering cord 15 downward, if the operation cord 20 is automatically guided from the guide roller 26 to the bottom rail 14 and the guide roller 26 by its own weight, the pulley 29 and The weight 30 may be omitted.
In the first embodiment, the length of the operation cord 20 guided between the guide roller 26 and the bottom rail 14 may be set by means other than the cord equalizer 19. As the means, a knot may be provided in the operation code, or movement of the operation code with respect to the support pieces 25a and 24b may be prevented by an adsorption means such as a magnet.
