DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an embodiment of a pleat curtain for right operation embodying the present invention. An upper screen 2 is suspended and supported from the head box 1, and an intermediate rail 3 is attached to the lower end of the upper screen 2.
[0014]
A lower screen 4 is suspended and supported from the intermediate rail 3, and a bottom rail 5 is attached to the lower end of the lower screen 4.
The bottom rail 5 is suspended and supported by a plurality of first elevating cords 6 suspended from the head box 1, and an upper end portion of the first elevating cord 6 is rotatably supported in the head box 1. It is wound around the winding pipes 7a and 7b.
[0015]
A drive shaft 8 is fitted into the center of the winding pipes 7a and 7b, and the drive shaft 8 is rotationally driven by operating an operation chain 9 suspended from the right end of the head box 1.
[0016]
Accordingly, the winding pipes 7a and 7b are rotated through the drive shaft 8 by the operation of the operation chain 9, and the first lifting / lowering cord 6 is spirally wound around the winding pipes 7a and 7b or unwound. The bottom rail 5 is raised and lowered.
[0017]
A speed adjusting device 10 and a stopper unit 11 are attached to the left end of the drive shaft 8. The speed adjusting device 10 suppresses the rotational speed of the drive shaft 8 to a predetermined value or less and sets the lifting speed of the bottom rail 5 to a predetermined value or less. In addition, when the bottom rail 5 and the intermediate rail 3 are lowered together with the intermediate rail 3 supported on the bottom rail 5, the lowering speed is controlled so as to be less than a predetermined value.
[0018]
The stopper unit 11 prevents the bottom rail 5 from dropping its own weight. When the intermediate rail 3 is supported on the bottom rail 5, the stopper unit 11 prevents the own weight from dropping based on the weight of the bottom rail 5 and the intermediate rail 3. To work.
[0019]
The intermediate rail 3 is suspended and supported at one end of a second lifting / lowering cord 12 suspended from the head box 1, and the other end of the second lifting / lowering cord 12 passes through a cord stopper 13 in the head box 1. The operation cord 15 is suspended from the right end of the head box 1 and connected via a cord equalizer 14.
[0020]
When the operation cord 15 is operated to pull out the second lifting / lowering cord 12 from the head box 1, the intermediate rail 3 is pulled up, and the second lifting / lowering cord 12 is moved to the head box 1 using the weight of the intermediate rail 3. If it is pulled in, the intermediate rail 3 descends.
[0021]
The cord stopper 13 prevents the weight of the intermediate rail 3 from dropping when the operation cord 15 is not operated.
Next, detailed configurations of the winding pipes 7a and 7b and the second lifting / lowering cord 12 for guiding the first lifting / lowering cord 6 will be described.
[0022]
In the head box 1, support members 16 are disposed at the suspended positions of the first and second lifting / lowering cords 6 and 12, respectively. As shown in FIG. 3, guide holes 17 a and 17 b through which the first and second elevating cords 6 and 12 can be inserted are formed on the bottom surface of each support member 16. 17 b is exposed on the lower surface of the head box 1.
[0023]
On the bottom surface of each support member 16, pulleys 18a and 18b are rotatably supported on the left and right sides of the guide holes 17a and 17b. As shown in FIG. 2, in the support member 16 that supports the winding pipe 7a, the second lifting / lowering cord 12 is guided to the cord stopper 13 through the guide hole 17a and the pulley 18a.
[0024]
A bearing portion 19 is formed on the upper portion of the support member 16, and the end portion of the winding pipe 7 a is rotatably supported by the bearing portion 19. The first lifting / lowering cord 6 is wound around the winding pipes 7a and 7b from below the head box 1 through the guide hole 17b and the pulleys 18a and 18b.
[0025]
The winding pipe 7b and the support member 16 that supports the winding pipe 7b are arranged symmetrically with respect to the winding pipe 7a and the support member 16 that supports the winding pipe 7a.
[0026]
In FIG. 4, the second lifting / lowering cord 12 is suspended from the left end of the head box 1 so that only the lifting / lowering operation of the intermediate rail 3 is performed on the left end side of the head box 1.
[0027]
In such a configuration, as shown in FIG. 5, in the support member 16 that supports the winding pipe 7a, the second elevating cord 12 is disposed on the left end side of the head box 1 via the pulley 18b. The speed adjusting device 10 and the stopper unit 11 are disposed on the right end side of the head box 1.
[0028]
Accordingly, a pleated curtain is formed by using the common parts for the left operation of the raising / lowering operation of the intermediate rail 3.
Now, in the pleated curtain configured as described above, if the operation chain 9 is operated, the first lifting / lowering cord 6 is wound around the winding pipes 7a and 7b or unwound from the winding pipes 7a and 7b. Thus, the bottom rail 5 is raised and lowered.
[0029]
Therefore, the lower screen 4 is expanded and contracted based on the raising and lowering of the bottom rail 5. Further, if the bottom rail 5 is lifted to the position where the intermediate rail 3 is suspended and then the bottom rail 5 is further lifted, the intermediate rail 3 is lifted by the bottom rail 5 and the upper screen 2 is folded toward the head box 1. Is included.
[0030]
Further, when the bottom rail 5 is lowered while the intermediate rail 3 is supported on the bottom rail 5, the intermediate rail 3 is lowered while being supported on the bottom rail 5, and the upper screen 2 is extended downward.
[0031]
Further, when the operation cord 15 is operated and the second lifting / lowering cord 12 is pulled out from the head box 1, the intermediate rail 3 is pulled up and the upper screen 2 is folded upward, based on the weight of the intermediate rail 3. If the second lifting / lowering cord 12 is pulled into the head box 1, the intermediate rail 3 is lowered and the upper screen 2 is extended downward.
[0032]
In the pleated curtain configured as described above, the following operational effects can be obtained.
(1) While supporting the winding pipes 7a and 7b for winding the first lifting / lowering cord 6 rotatably on the support member 16, the second lifting / lowering cord 12 is corded from the outside of the head box 1 by the support member 16. Guide toward the stopper 13 is possible. Therefore, since the first and second lifting cords 6 and 12 can be guided by the common support member 16, the number of parts can be reduced.
(2) Since the guide holes 17a and 17b for inserting the first and second elevating cords 6 and 12 are independently formed on the bottom surface of the support member 16, the first and second elevating cords are provided. 6 and 12 can be prevented from being entangled.
(3) By using common parts, a pleated curtain for the right operation or only the lifting operation of the intermediate rail 3 for the left operation can be configured.
[0033]
The above embodiment can be modified as follows.
The second lifting / lowering cord 12 may be wound around the winding pipes 7 a and 7 b and the first lifting / lowering cord 6 may be pulled out from the end of the head box 1.
The operation chain 9 may be provided at the right end of the head box 1. In this case, when a common operation device is used, the operation direction of the operation chain 9 is opposite to the screen elevation direction.
A single pulley may be provided directly above the guide holes 17a and 17b of the support member 16 so that the second lifting / lowering cord 12 can be guided in either the left or right direction using the pulley.
[0034]
【The invention's effect】
As described above in detail, the present invention can provide a shielding material lifting / lowering device for a solar radiation shielding device that can reduce the number of components.
