Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind for a skylight that adjusts the lighting from the skylight by pulling out or folding a shade formed in the shape of a fold with cloth or the like along the skylight.

[0002]

2. Description of the Related Art In a skylight blind, a shade made of a piece of cloth such as cloth is supported by a plurality of suspension shafts at regular intervals, and both ends of each suspension shaft are guided by runners. Supported by.

A pulley is rotatably supported near both ends of the guide rail, and an endless wire is hung between the pulleys. The leading runner of the runner is connected to the wire, and one pulley is rotatably driven by a driving means such as a motor. Further, each suspension shaft is connected to an adjacent suspension shaft by a pitch cord.

With such a structure, when the pulley is rotationally driven in the shade drawing direction, the leading runner is drawn out, and along with this, the succeeding runners are sequentially drawn out at regular intervals, and the shade is guided along the guide rail. Be withdrawn.

When the pulley is driven to rotate in the shade folding direction, the leading runners are pulled back, and the respective runners are sequentially pushed back by the leading runners, and the shades are folded along the guide rails.

[0006]

In the above-mentioned skylight blind, it is necessary to move the leading runner from one end to the other end of the guide rail when opening and closing the shade. Therefore, it takes a long time to open and close the shade, which may be a problem when linked with other disaster prevention equipment in an emergency.

[0007] Further, if an attempt is made to increase the transfer speed of the leading runner to shorten the opening / closing time, it may cause various failures such as the runner not moving smoothly in the hanger rail and the shade being caught.

An object of the present invention is to provide a skylight blind which can shorten the opening and closing time of the shade without increasing the transfer speed of the suspension shaft supporting the shade.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a plurality of fixed suspension shafts which are immovable with respect to a window frame and are arranged at equal intervals. Each of the movable suspension shafts is movably disposed with respect to the window frame, and both ends of the shade are suspended and supported by the movable suspension shafts and a fixed suspension shaft adjacent to one of the movable suspension shafts. An opening / closing device is provided for moving the movable suspension shaft in a state in which the movable suspension shaft is equidistant from the fixed suspension shaft.

Further, the opening / closing device includes a wire connecting the movable suspension shafts at equal intervals, a winding shaft for winding or rewinding the wire and transferring the wire, and a motor for driving the winding shaft. Composed of.

[0011]

When the movable suspension shaft is moved by the opening / closing device by the distance between the fixed suspension shafts, the shade is opened / closed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a skylight blind has a plurality of fixed suspension shafts 2 and a movable suspension shaft 3 supported between a pair of guide rails 1 attached to a window frame of the skylight or the like. . The fixed suspension shaft 2 and the movable suspension shaft 3 are arranged alternately.

The fixed suspension shaft 2 is fixed to the guide rail 1 at equal intervals so as not to move. The movable suspension shaft 3 is movably supported by the hanger rail 1 via runners 4 provided at both ends thereof.

The fixed suspension shaft 2 and the movable suspension shaft 3 which are adjacent to each other respectively suspend and support both ends of the shade 5. Therefore,
A large number of independent shades 5 are suspended and supported between a fixed suspension shaft 2 and a movable suspension shaft 3 which are adjacent to each other.

Winding shafts 6 and 7 are rotatably supported by a window frame via brackets 8 near both ends of the guide rail 1, and the winding shafts 6 and 7 are rotationally driven by a motor (not shown). It

Two wires 9 are stretched in parallel between the winding shafts 6 and 7, and both ends of the wire 9 are wound on the winding shafts 6 and 7.
Is wrapped around. Then, by rotating one of the winding shafts 6 and 7 to wind the wire 9, the wire 9 is moved from the other winding shaft toward the one winding shaft.

The movable suspension shafts 3 are connected to the wires 9 at the same intervals as the fixed suspension shafts 2. Therefore, when the wire 9 is moved, the movable suspension shaft 3
Are moved at equal intervals.

Next, the operation of the skylight blind constructed as described above will be described. FIG. 2 shows the shade 5 closed. In this state, the movable suspension shaft 3 is in contact with the fixed suspension shaft 2 on the opposite side of the pair of fixed suspension shafts 2, and the movable suspension shaft 3 and the fixed suspension shaft 3 which are located apart from each other. A shade 5 is hung and supported between the shade 5.

When the winding shaft 6 is rotationally driven from this state and the wire 9 is moved in the direction of arrow A, the movable suspension shafts 3 are moved in the same direction at equal intervals. When the movable suspension shafts 3 are moved until they come into contact with the pair of fixed suspension shafts 2, the shade 5 is opened as shown in FIG.

If the winding shaft 7 is rotationally driven from this state and the wire 9 is moved in the direction of arrow B, the state shown in FIG. 2 is restored. As described above, in this skylight blind, when the shade 5 is opened and closed, each movable suspension shaft 3 may be moved by the distance between the fixed suspension shafts 2. Therefore,
The shade 5 without increasing the transfer speed of the wire 9
The time required to open and close can be shortened.

In the above embodiment, the winding shafts 6 and 7 are rotated by the motors, respectively.
One may be rotationally driven by a motor, and the other winding shaft may be biased in a direction in which the wire 9 is always tensioned by a biasing means such as a torsion coil spring.

The technical ideas other than the claims that can be understood from the above-described embodiments will be described below along with their effects. (1) A plurality of fixed suspension shafts are arranged immovably and at equal intervals with respect to a guide rail fixed to a window frame, and movable suspension shafts are respectively provided between the fixed suspension shafts. Movably arranged along each of the movable suspension shafts and the fixed suspension shafts adjacent to one of the movable suspension shafts and one of the movable suspension shafts. The suspension shaft was connected to a wire at an interval equal to that of the suspension shaft, and the wire was transferred by a winding shaft driven by a motor. The shade can be opened and closed by rotating the winding shaft and moving the wire by the distance between the fixed suspension shafts.

[0023]

As described above in detail, according to the present invention, it is possible to increase the transfer speed of the suspension shaft for supporting the shade,
It is possible to provide a skylight blind that can shorten the opening and closing time of the shade.
