That is, in the window blind, a large number of runners 12 are movably supported by a pair of guide rails 11, and a large number of support frames 1 for supporting a shade 13 described later are provided between the runners 12 of both guide rails 11.
4 are supported.

Each of the support frames 14 has a first support member 15 in the form of a rectangular cylinder, the ends of which are supported by the runner 12.
The first support member 15 is composed of a pair of second support members 17 that are fixed to both side surfaces of the first support member 15 with screws 16.

As shown in FIG. 3, the second supporting member 1
7, a supporting piece 18 is formed which can be brought into contact with the side surface of the first supporting member 15, and a hanging cylinder 19 having an opening 20 in a part of the cylinder is formed below the supporting piece 18. Has been formed. Then, in each of the support frames 14, the pair of suspension cylinders 19 of the second support member 17 are fixed to the first support member 15 so that the openings 20 thereof face each other.

As shown in FIG. 2, the second support member 1
The support piece 18 of No. 7 is formed to have the same length as the first support member 15 arranged between the guide rails 11, and the suspension cylinder 19 of the second support member 17 is formed to be longer than the support piece 18. And is extended to a position below the guide rail 11.

A hook 30 having an inverted T-shaped cross section is formed in the lower portion of the first support member 15, and the hook 30 is provided on one side of the support piece 18 of the second support member 17. A hooking piece 31 whose tip extends obliquely downward so as to be hooked is formed. Then, when attaching the second support member 17 to the first support member 15, by engaging the latching piece 31 with the latching portion 30, the mounting holes of both the supporting members 15 and 17 are aligned, The second support member 17 can be easily attached to the first support member 15 by screwing the screw 16 into the attachment hole.

As shown in FIG. 1, a shade 13 is suspended and supported between adjacent suspension cylinders 19 of adjacent support frames 14. That is, as shown in FIG. 3, in the shade 13, both ends of a cloth or the like are folded back to form a bag portion 21, and the bag portion 21 is inserted into the suspending tube 19 and is then inserted into the bag portion 21. A round bar-shaped shade retainer 22 is inserted.

The diameter of the shade presser 22 is formed to be larger than the opening width of the opening 20 of the hanging cylinder 19 to prevent the shade from coming off the opening 20, so that the shades 13 are adjacent to each other in the supporting frame 14. It is hung and supported in a fold shape between the adjoining hanging cylinders 19. The shade 13 is suspended and supported over the entire length of the suspension cylinder 19 so as to hide the guide rail 11 from the view from below.

Further, in the support frame 14 supported by the leading runner 12a, the shade 13 is suspended and supported from the suspension cylinder 19 in the front in the runner pull-out direction, and the suspension cylinder 19 that does not suspend and support the shade 13 is the same. It is configured to be covered by the shade 13.

The support frames 14 are connected by pitch cords 23, and the pitch cords 23 set the maximum distance between the support frames 14 so that the shade 13 between the support frames 14 is maintained in a fold shape. .

A drive shaft 25 rotatably driven by a motor 24 is rotatably supported on one side between the guide rails 11, and both ends of the drive shaft 25, that is, the drive shaft 25 in each guide rail 11. The sprocket 26 is fixed.

A chain 27 is attached to each sprocket 26.
And a chain 27 of the chain guide 28 is integrally formed on the upper and lower parts of the guide rail 11.
It is movably supported along a and 28b. And
The leading runner 12a is attached to the end of the chain 27 supported by the lower chain guide 28a via a mounting member 29.

Therefore, the sprocket 26 is rotated and the chain 2 supported by the lower chain guide 28a is rotated.
When 7 is moved, the leading runner 12a is moved along with the movement of the chain 27.

In the skylight blind constructed as described above, the motor 24 is actuated to operate the sprocket 26.
When the chain 27 supported by the lower chain guide 28a is moved in the direction of arrow A in FIG. 1, the leading runner 12a is moved as the chain 27 moves.

Then, the support frame 14 supported by the leading runner 12a is moved along the guide rails 11, and the subsequent support frames 14 connected via the pitch cords 23 are sequentially pulled out at regular intervals. As a result, the shade 20 that is suspended and supported in a fold shape between the support frames 14 is pulled out between the guide rails 11.

On the other hand, when the chain 27 supported by the lower chain guide 28a is moved in the direction of arrow B in FIG.
Leading runner 12a as the chain 27 moves
Will be moved.

Then, the support frame 14 supported by the leading runner 12a is moved along the guide rails 11, and the subsequent support frames 14 are sequentially pushed back by the support frame 14. As a result, the shade 13 is folded in the same direction.

As described above, in this window blind,
It is possible to pull out and fold the shade 13 by pushing out or pulling back the chain 27 hooked on the sprocket 26 along the lower chain guide 28a of the guide rail 11 and moving the leading runner 12a. Therefore, as a drive mechanism, a chain 27 longer than the maximum movement distance of the shade 13 may be mounted on the sprocket 26, and the leading runner 12a may be connected to the end of the chain. It can be constructed very easily as compared with a configuration in which the leading runner is connected to the wire in a stretched state.

Further, one shade 13 is hung and supported between the adjacent support frames 14, each shade 13 is configured to form one fold, and supports the end portion of each shade 13. The second support member 17 is attached to the first support member 15 with screws 16.

Therefore, when some shades 13 are damaged or soiled, the second support member 17 supporting the shades 13 is removed from the first support member 15 and the shade retainer 22 is pulled out. Same shade 13
After the replacement, the second support member 17 may be attached to the first support member 15 again.

Therefore, when a part of the shade 13 is damaged or soiled, its replacement work can be performed very easily.
