Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pleated shade for a skylight.

[Prior art and its problems] Conventionally, pleated shade has a lifting cord that passes through the main fabric, and is also used as a fabric aligning device when opening and closing.

However, when opening and closing along the guide rail, especially at the curved part of a skylight found in sunrooms, the predetermined tension of the lifting cord moving through the fabric, that is, the tension corresponding to the opening/closing operation force, is applied to the curved part of the skylight. This causes a component of force that acts in the direction of the inner diameter of the cloth, causing the inconvenience of crushing the raw cloth. In addition, if the cord 62 is lengthened so as not to crush the raw cloth and the raw cloth 2 is adjusted to the open state as shown in FIG. 5a,
When the raw cloth 2 is closed, the cord 62 becomes slack as shown in FIG. 5b, and the cord 62 protrudes from the guide rail 1, causing an inconvenience in that the raw cloth 2 is not aligned. Therefore, there was a problem in that it was impossible to use a lifting cord or the like having a relatively large tension corresponding to the opening/closing operation force by penetrating the main body fabric.

On the other hand, if the movement of the cloth is not aligned, for example, when moving the cloth 2 from an open state to a closed state for a long period of time as shown in FIG. 6a,
The pleated part of the raw fabric may develop a habit in the open state, making it impossible to line up as shown in Figures 6b and c, or a similar situation may occur due to the deterioration of the pleats, which may eventually cause the fabric to become unable to open or close. The problem was that it could be possible.

Therefore, a method has been considered in which guide parts are attached to the ends of the pleats and guided in the rail grooves, but in this case, the folding margin becomes large and there is a problem that a sufficient open state cannot be obtained.

The present invention solves the above-mentioned problems and provides a pleated shade for a skylight in which raw cloth and a movable box are opened and closed by being guided by a guide rail having a horizontal part in a nearly horizontal state and a curved part in a curved state. To provide a pleated shade for a skylight that is automatically adjusted and maintains the alignment of raw fabric during opening and closing.

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the invention, the pleated shade for a skylight according to the present invention is characterized by the following structure. In other words, the cloth and the moving box are opened and closed by being guided by a guide rail that has a horizontal part that is almost horizontal along the slope of the roof and a curved part that is continuously curved downward toward the eaves side of the horizontal part. In the pleated shade for a skylight, an end cap is provided at an end of the movable box in a direction intersecting with the opening/closing direction,
providing a wire along the guide rail that passes through a through hole drilled in the raw cloth and the end cap and is slidable on the raw cloth and the end cap;
It is characterized in that both ends of the wire are supported by guide rails, and a spring is provided at one end or both ends of the wire to apply tension to the wire.

[Example] An example of the present invention shown in the drawings will be described in detail below. FIG. 1 is a partially cutaway plan view, FIG. 2 is a partially cutaway front view, and FIG. 3 is a partially cutaway right side view. Here, 1 is a guide rail, 2 is raw cloth, 21
3 is a moving box, 4 is a head box, 5 is an end frame, 6 is a wire, 7 is a wire spring, 8 is an end cap, and 81 is a through hole.

In this embodiment, the raw cloth 2 is guided by a guide rail 1 that has a horizontal part that is almost horizontal along the slope of the roof and a curved part that is continuously curved downward on the eaves side of the horizontal part. This invention relates to a pleated shade for a skylight in which a movable box 3 operates to open and close. The pleated shade for a skylight forms a frame body consisting of one head box 4, two guide rails 1, and one end frame 5, and has two guide rails 1 and guides in the frame body. A raw cloth 5 is arranged in a pleated manner between the movable box 3 and the head box 4.
The movable box 3 is moved to open and close the box. In this embodiment, guide plates 11 are attached to both ends of the moving box 3 in a direction intersecting the opening/closing direction.
The guide roller 12 arranged on the guide rail 1
Since the moving box 3 is guided by the rails 14 formed in the same direction, the movement of the moving box 3 is performed smoothly. Further, a magnet 91 is provided in the head box 4, and a magnet plate 92 is provided in the moving box 3, so that when the cloth 2 is closed, the adhesive force between the magnet 91 and the magnetic plate 92 prevents the cloth 2 from opening. Hold. When opening the cloth 2, it can be opened by applying a baton stick to the baton catch 31 and moving it.

The wire 6 is provided along the guide rail 1,
Moreover, it is supported at both ends of the guide rail 1.
That is, the wire 6 is provided along the guide rail 1 between the head box 4 and the end frame 5, as shown in FIG.

Further, the state in which the wire 6 is supported at both ends of the guide rail 1 is as follows. In this embodiment, the spring 7 is provided only on the head box 4 side to apply tension to the wire 6, and the spring 7 is not provided on the end frame 5 side, but the spring 7 is provided only on the end frame 5 side. Alternatively, it may be provided on both sides of the head box 4 and the end frame 5.

In this embodiment, the wire 6 is fixedly attached to the end frame 5 by screws 51 on the end frame 5 side. Also, Headbox 4
On the side, a spring 7 is stretched between an end cap 8 disposed at the end of the head box 4 and a wire bush 61. Here, as shown in FIGS. 1 and 3, the wire 6 is connected to the end cap 8.
Since the end bush 61 is fixed to the wire 6, the wire 6 is stretched along the guide rail 1 between the head box 4 and the end frame 5.

Since this embodiment is formed as described above,
The wire 6 passes through a through hole 21 made in the raw cloth 2 and a through hole 81 made in an end cap 8 provided at the end of the moving box 3. Therefore, when a baton rod is applied to the baton catch 31 of the movable box 3 and the baton is moved, the wire 6 slides through the through hole 21 bored in the cloth 2 and the through hole 81 of the end cap 8, and the movable box is moved to a desired position. 3 can be moved. In addition, since a spring is installed to apply tension to the wire 6, the wire 6 remains appropriately tensioned even when the raw cloth 2 is opened or closed, and the raw cloth 2 is not crushed or The cord does not become sagging, and the opening/closing operation can be performed satisfactorily.

Incidentally, FIG. 4 is a perspective view showing the relationship among the movable box 3, raw cloth 2, and end cap 8. A bar 32 is inserted into the recess of the moving box 3, and the raw cloth 2 is attached to one side of the bar 32 with double-sided tape. Further, the end cap 8 is fixed by inserting the leg portions 82 of the end cap 8 into both ends of the moving box 3 and the bar 32. Since the moving box 3 and the head box 4 have the same shape, the relationship among the head box 4, raw cloth 2, and end cap 8 is the same as when the moving box 3 is replaced with the head box 4.

[Effects of the invention] Since the present invention is constructed as described above, there is provided a pleat for a skylight in which raw cloth and a movable box are opened and closed by being guided by a guide rail having a horizontal part in a substantially horizontal state and a curved part in a curved state. In the shade, the amount of wire fed out is automatically adjusted, and the cloth alignment during opening and closing is maintained normally.
