Description

[Detailed Description of the Invention] The object of the present invention is to equip a shutter with an arbitrary pattern between the horizontal rods to give it a beautiful appearance, and to make it foldable so that the storage space in the attic can be made as small as possible. .

The details will be explained below with reference to the drawings. A pair of left and right inner and outer two-striped guide rails 5, 6 are provided, and the upper part of the two-striped guide rails 5, 6 is bent inward, and moves up and down along these two-striped guide rails 5, 6. A plurality of frames C are arranged at equal intervals so that each frame C is connected to a pair of left and right working rods A that are shaped like a letter when viewed from the side, and the upper inner ends of the left and right working rods A. A horizontal rod 7 that connects the upper shaft bearing holes 3 and the lower shaft bearing holes 4 at the lower outer ends, and the two-striped guide rails 5, 6 at the upper outer ends and lower inner ends of the left and right engineered rods A. It consists of upper and lower engaging rolls 1 and 2 that are pivotally supported so as to project sideways, and the lower engaging roll 2 located at the lower inner end of the upper and lower engaging rolls 1 and 2 is provided with a two-striped guide rail 5,
The engagement upper roll 1, which is engaged with the inner guide rail 5 of 6 and located at the upper outer end, engages with the outer guide rail 6 of the two-striped guide rails 5 and 6, and the upper and lower engagement rolls 1 engage with the outer guide rails 6 of the two-striped guide rails 5 and 6, and each frame body C located above and below The horizontal rods 7 are connected on both sides by connecting rods 8 having the same length as the engineered rods A, and an arbitrary pattern body B is provided between each horizontal rod 7. 10 is a coil spring, 11 is a suspension rope for the shutter, and 12 is a pulley. Incidentally, instead of the coil spring, a heavy spring or a manual spring may be used.

In the present invention, as described above, the lower engaging roll 2 pivotally supported on the engineered rod A engages with the inner guide rail 5, and the upper engaging roll 1 engages with the outer guide rail 6. In addition to being strong against force, the line of action of the working rod A is inclined, and the working rod A is located at the bent portion (R) above the double guide rails 5 and 6.
Since the opening and closing of the folding shutter can be made extremely smooth, the folding shutter can be opened and closed smoothly.

Furthermore, since the shutter according to the present invention is foldable, not only does it require a small storage space on the ceiling, but it is also convenient for transportation and storage. In addition, in the embodiment shown in the drawings, the horizontal rod 7 is
Since the pattern B is connected to the
It can be equipped directly.

Claims (1)

[Claims] 1. A pair of left and right inner and outer two-striped guide rails are provided, the upper part of the two-striped guide rails is bent inward, and a plurality of frames are arranged at equal intervals so as to move up and down along these two-striped guide rails, Each of these frames includes a pair of left and right engineered rods that are shaped like a letter when viewed from the side, and a horizontal rod that connects the upper shaft receiving holes at the upper inner ends and the lower shaft receiving holes at the lower outer ends of the left and right engineered rods, respectively. and upper and lower engaging rolls that are pivotally supported at the upper outer ends and lower inner ends of the left and right engineered rods so as to protrude toward the two-striped guide rail, and the lower inner end of the upper and lower engaging rolls. The lower engagement roll located at the upper and lower ends engages with the inner guide rail of the two-strip guide rail, and the upper engagement roll located at the upper outer end engages with the outer guide rail of the two-strip guide rail and is located above and below. A folding shutter in which the horizontal rods of each frame are connected on both sides by continuous rods of the same length as the engineered rods, and each horizontal rod is equipped with an arbitrary pattern.
