DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a large number of guide supports 2 are movably supported between a pair of guide rails 1a and 1b disposed in parallel on both sides of the skylight.

In the guide rails 1a and 1b, an endless chain 3 is movably disposed as a cord-like member.
The chain 3 is mounted on a drive gear 18 rotatably supported at one end of the guide rails 1a and 1b. On one of the guide rails 1a and 1b, an induction unit 4 having a built-in motor is disposed.
The chain 3 moves within 1b.

The leading guide support 2a of the plurality of guide supports 2 has guide rails 1a and 1a at both ends.
It is locked to the chain 3 within b. Therefore, when the chain 3 moves in the guide rails 1a and 1b, the guide support 2a moves together with the chain 3.

The guide supports 2 and 2a are connected to adjacent guide supports by a pitch code 5, respectively. The pitch codes 5 are set to the same length. Accordingly, when the leading guide support 2a moves in the direction of arrow A in FIG. 2, the subsequent guide supports 2 move in the same direction at equal intervals. When the guide support 2a moves in the direction of arrow B, each subsequent guide support 2 is sequentially pushed back in the same direction by the guide support 2a.

A screen 6 is suspended from each of the guide supports 2, 2a. Each screen 6
A weight bar 7 is suspended and supported at the lower end. As shown in FIG. 1, an opening / closing unit 8 is disposed above the guidance unit 4. The opening / closing unit 8 has a built-in motor inside a winding drum 10 rotatably supported between support frames 9, and operates the winding drum 1 by operating the motor.
0 is rotated.

A base end of a drive wire 11 is wound around the winding drum 10, and a distal end of the drive wire 11 is connected to a pulley 12 provided at the other end of each of the guide rails 1a and 1b. It is connected to a weight bar 7 suspended and supported from the leading guidance support 2a via the guidance support 2. Therefore, the leading end of the drive wire 11 is guided obliquely from the guide support 2a to the weight bar 7 suspended and supported from the guide support 2a adjacent to the leading guide support 2a.

The weight drive bars 7 suspended from the guide supports 2 other than the leading guide support 2a have branch drive wires 1 branched from the drive wires 11, respectively.
3 is connected, and the base end of the branch drive wire 13 passes through the guide support 2 located immediately after the guide support 2 on which the weight bar 7 is suspended and supported, and is connected via a wire joint 14 to the drive wire. 11 is connected.

The lengths and connection positions of the drive wires 11 and the branch drive wires 13 are adjusted so that the screens 6 hang down at equal intervals so as to be evenly tensioned.

Weights 17 are attached to the distal ends of the drive wires 11 and the branch drive wires 13 in the vicinity of the respective weight bars 7, and the weights 17 drive between the respective weight bars 7 and the guide support 2. The wire 11 and the branch drive wire 13 are tensioned.

A limit switch 15 is provided on a side surface of the guide unit 4 on the guide support 2a side, and a pressing member 16 is attached to the guide support 2a at a position facing the limit switch 15. Guidance support 2
The maximum movement range of a is detected based on the number of rotations of the motor in the guidance unit 4 and the guidance support 2a is automatically stopped. When an error occurs in the detection of the number, the pressing member 1
When 6 presses the limit switch 15, the operation of the motor is stopped, and the further movement of the guide support 2a in the same direction is stopped.

Next, the operation of the skylight blind constructed as described above will be described. When the leading guidance support 2a is moved in the direction of arrow A by operating the guidance unit 4 to move the chain 3, the subsequent guidance support 2 follows at regular intervals. And guidance unit 2
When the pressing member 16a presses the limit switch 15, the movement of the guide support 2a is stopped, and the guide supports 2a and 2 are pulled out at equal intervals as shown in FIG.

In this state, since each screen 6 is vertically suspended from each of the guiding supports 2a and 2, the light is transmitted from right above the skylight and blocked from oblique directions. Become.

In this state, when the opening / closing unit 8 is operated to wind the drive wire 11 around the winding drum 10, each weight bar 7 is connected to the subsequent guide support 2 by the drive wire 11 and each branch drive wire 13. Lifted diagonally upward.

Then, as shown in FIG. 3, when each weight bar 7 is lifted to the vicinity of the succeeding guide support 2, the external light from the skylight is substantially blocked by the screen 6.

When the leading guide support 2a is moved in the direction of arrow B from the state shown in FIG. 1, the subsequent guide supports 2 are sequentially pushed back, and as shown in FIG. , 1b.

In this state, the blinds are opened, and outside light can be introduced from the skylight into the room. With the skylight blind configured as described above, the following operational effects can be obtained. (A) Since the screen 6 hanging from the guiding supports 2 and 2a can be pulled out and folded along the guide rails 1a and 1b, the blind can be completely opened by folding the screen 6. (B) With the screen 6 pulled out, the opening / closing unit 8 is operated to drive the drive wire 11 and the branch drive wire 13.
, Each weight bar 7 moves between the lower end of the screen 6 hanging from the guide supports 2 and 2a and the subsequent guide support 2. Accordingly, the screen 6 is in a state between a state in which the screen 6 is suspended vertically as shown in FIG. 1 and a state in which the screen 6 is suspended and supported between the guiding supports 2 and 2a as shown in FIG. Can be arbitrarily adjusted. As a result, the amount of light collected from the skylight can be arbitrarily adjusted. (C) Since the weight 17 is attached to the drive wire 11 and the branch drive wire 13 near each weight bar 7, the drive wire 11 and the branch drive wire 1 are attached.
3 is always nervous. Therefore, even when the screen 6 is folded as shown in FIG. 4, it is possible to prevent the drive wire 11 and the branch drive wire 13 from being sluggish due to slackness. (D) Weight bars 7 other than the first weight bar 7
The distal end of the branch drive wire 13 is connected, and the base end of the branch drive wire 13 passes through the guide support 2 immediately after when each guide support 2 is located at the interval set by the pitch code 5. 11 is connected.
Therefore, even if the number of screens 6 increases, only the drive wire 11 and one branch drive wire 13 are guided on each guide support 2, and by the action of the weight 17, It is possible to reduce the frequency of occurrence of unnecessary interference, snagging, and the like of the wires 11, 13 during the operation of pulling out and folding the screen 6.

It should be noted that a belt may be used instead of the chain 3, and a leading guide support may be attached to the belt.
