DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. As shown in FIG. 1, bottom weights 2 are suspended and supported at the lower ends of the slats 1 of the vertical blind, and the bottom weights 2 are connected by bottom cords 3.

As shown in FIG. 2, the bottom weight 2
Is composed of a weight plate 4 around which the lower end of the slat 1 is wound, and a frame 5 into which the weight plate 4 is fitted.

The weight plate 4 is formed of a metal plate such as zinc die cast or a plate of high specific gravity resin, and a slit 6 is formed on the upper part thereof except for both ends in the left-right direction.
It is composed of a first weight plate 4a above the slit 6 and a second weight plate 4b below the slit 6.
The vertical width of the first weight plate 4a is sufficiently smaller than the vertical width of the second weight plate 4b, for example, 10 mm.

The first weight plate 4a and the second weight plate 4b are connected to each other via connecting portions 7 left on both sides of the slit 6, and the connecting portions 7 are located at the same height on both front and back surfaces. As shown in FIG. 3, a groove 8 having a V-shaped cross section is formed. Then, the first weight plate 4a can be folded from the second weight plate 4b along the concave line 8.

The frame 5 is made of synthetic resin in a shape of a square frame having an opening at the bottom, and a slit 9 is formed on the upper side thereof so that the slat 1 can be inserted therethrough. A support groove 10 is formed inside the side of the frame 5 over the entire length of the side, and the weight plate 4 can be inserted between the support grooves 10.

Bottom weight 2 constructed as described above
For assembling, first, the lower end of the slat 1 is inserted into the slit 9 of the frame 5, and then inserted into the slit 6 of the weight plate 4. Then, the lower end of the slat 1 is aligned with the edge of the first weight plate 4a, and the double-sided tape 11 is attached to the side surface of the first weight plate 4a.

Then, the slat 1 is wound around the weight plate 4 once, and in that state, the weight plate 4 is inserted into the support groove 10 from below the frame 5. Then, as shown in FIG. 4, the weight plate 4 and the frame 5 are suspended and supported by the lower end portion of the slat 1, and the bottom weight 2 is configured. In this state, the weight plate 4 is covered with the slats 1.

When the length is to be packed with the bottom weight 2 as described above, the weight plate 4 is removed from the frame 5, and the first weight plate 4a is separated from the second weight plate 4b by folding at the recess 8 portion. Then, the first weight plate 4a is inserted between the support grooves 10 in a state where the first weight plate 4a is rotated 180 degrees in the winding direction of the slat 1, and then the second weight plate 4b is inserted into the support groove 10. Insert it in between.

Then, as shown in FIG. 5, the weight plate 4 and the frame 5 are suspended and supported on the lower end portion of the slat 1, and the lower end portion of the slat 1 corresponds to the first weight plate 4a by a half circumference as compared with FIG. It will be in a state of being wound a lot.

Therefore, the slat 1 has the first weight plate 4
The length is packed by about 10 mm, which corresponds to the vertical width of a. Also,
When lengthening is performed from the state shown in FIG. 4, the weight plate 4 is similarly removed from the frame 5, and the first weight plate 4a is separated from the second weight plate 4b by folding at the recess 8 portion. Then, the first weight plate 4a is inserted between the support grooves 10 in a state where the first weight plate 4a is rotated 180 degrees in the direction in which the slat 1 is rewound, and then the second weight plate 4b is inserted into the support groove 10. Insert it in between.

Then, as shown in FIG. 6, the weight plate 4 and the frame 5 are suspended and supported by the lower end portion of the slat 1, and the lower end portion of the slat 1 corresponds to a half circumference from the first weight plate 4a as compared with FIG. It will be rewound.

Therefore, the slat 1 includes the first weight plate 4
The length is extended by about 10 mm, which corresponds to the vertical width of a. As described above, in the bottom weight 2, when the slats 1 set to have the same length in advance are to be lengthened or lengthened, the first weight plate 4a is folded and cut off to remove the first weight. By winding the slat 1 around the plate 4a or unwinding the slat 1 from the first weight plate 4a, the length of the slat 1 can be lengthened or lengthened in units of 10 mm.

Therefore, it is extremely easy to lengthen and lengthen each slat 1 with the same length. Further, since the weight plate 4 is covered with the slats 1, it is aesthetically preferable.

Further, the first weight plate 4a and the second weight plate 4b are separated when performing the length packing or the length extension, but the first weight plate 4a and the second weight plate 4a are separated from each other. 4b may be separated from the beginning.

If the width of the first weight plate 4a is reduced, the length packing and length extension can be adjusted more finely. Further, although the lower end of the slat 1 is adhered to the first weight plate 4a with the double-sided tape in the above-mentioned embodiment, it may be adhered with an adhesive material. Further, other joining means may be used.
