Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind slat manufacturing method and a blind slat.

[0002]

2. Description of the Related Art As a conventional blind slat,
An aluminum alloy material is used as a raw material, which is colored. We have made changes by increasing the number of colors and coloring.

[0003]

However, the conventional slats described above are not satisfactory in terms of design, texture, and high quality. Therefore, a method has been proposed in which a bag is made of cloth, paper, non-woven fabric, etc., and an aluminum alloy slat material is inserted into the bag as a core material. It is a big obstacle to popularization. The present invention is intended to solve such a problem.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above problems by integrating a sheet material with a slat core material formed by stretching a metal plate material that has been slit. That is, in the method for manufacturing a blind slat of the present invention, a plurality of slits (slits and slits) are provided in a metal plate at predetermined intervals in the longitudinal direction thereof, and these slits form a space. As described above, the slat core is formed by stretching the plate material in the longitudinal direction, and the slat is configured by integrating the sheet material with the slat core. Further, the blind slat of the present invention covers both sides of a long slat core material in which space portions formed by extending the slit portion in the longitudinal direction are provided at predetermined intervals in the longitudinal direction, and the slat core material. Sheet material integrated with this,
Composed of.

[0005]

[Function] Since the slat is formed by integrating the sheet material with the metal slat core material, it is possible to secure the necessary performance as the slat material, such as shape, shape retention and strength, and use various sheet materials. As a result, the design aspect can be improved. Further, a sheet material having waterproofness and moisture resistance can be used. Since the slat core material is formed by stretching a metal plate material, it is possible to use less material than the conventional material to form a slat having the same size as the conventional slat. Therefore, the weight of the slats is reduced.

EXAMPLE FIG. 1 shows a plate material 12 before being used as a slat core material 10 (see FIG. 2). The plate member 12 is long and has a thickness of 0.1 to 10.
A 0.2 mm steel plate material is used. The plate member 12 is provided with a plurality of slits 14 (cutting portions) at predetermined intervals in the longitudinal direction. The slits 14 are provided orthogonal to the long side 16 of the plate material 12, and the adjacent slits 14
A short notch 18 (cutting portion) is provided in parallel with the slit 14 from the ends of the two long sides 16 of the plate material 12. As shown in FIG. 2, the plate member 12 is stretched in the longitudinal direction so that the slits 14 and the notches 18 provided therein form the spaces 19 and 20, respectively.
The slat core material 10 is used. At this time, the plate member 12 is stretched 4 to 5 times until its width becomes about 15 mm to 50 mm which is the slat width. By stretching
Although the width of the plate member 12 is reduced, the thickness of the plate member 12 hardly changes because the length is increased by reducing the width. As shown in FIG. 3, the slat core material 10 has a gentle arcuate cross section. Next, as shown in FIG. 4, the slat core material 10 is covered with a sheet material 21 such as vinyl chloride or polyester film and heat-sealed. Thereby, the slats 22 are formed. FIG. 5 shows a sectional view of the slat 22. As shown in the figure, the slat 22 has both sides and ends of the slat core 10 covered with sheets 21, and the sheet material 21 covering both sides of the slat core 10 enters the space portion 19. The surfaces of these sheet materials 21 facing each other are fused. As a result, as shown in FIG. 6, a concavo-convex pattern conforming to the shapes of the space portions 19 and 20 is obtained. The sheet material 21 may have a thickness that does not break during normal use. Since the entire surface of the slat core material 10 is covered with the sheet material 21, it is possible to prevent the steel sheet material from rusting. Even if you use a steel plate material with the same thickness as a conventional aluminum alloy slat material, it is stretched and used, so the amount of material used is 1 /
4 to 1/5 is enough. As a result, even if the specific gravity of the steel sheet material is high, the weight of the slat material can be reduced.

Next, a second embodiment shown in FIGS. 7 and 8 will be described. FIG. 7 shows the plate material 12. Plate 12 is first
Like the embodiment, a long steel plate material having a thickness of 0.1 to 0.2 mm is used.

The slit 14 is provided from a position slightly inside the end of the long side 16 of the plate 12 to a position slightly beyond half of the short side 24. The slits 14 that are adjacent to each other are provided in the directions of the long sides 16 facing each other. That is, the slits 14 are provided so that the ends of the slits 14 adjacent to each other near the center in the direction of the short side 24 are slightly overlapped with each other at a predetermined interval in the longitudinal direction. A short cut 18 is provided at the same position in the longitudinal direction as the slit 14 and from the end of the long side 16 facing the slit 14. As shown in FIG. 8, the plate member 12 has a width of 4 to 4 in the longitudinal direction of the plate member 12 until the width of the plate member 12 becomes the slat width so that the space portions 19 and 20 are formed in the slits 14 and the notches 18. The slat core material 10 is stretched 5 times to obtain the slat core material 10. At this time, the thickness of the plate material 12 hardly changes. As shown in FIG. 8, a slat 22 is formed by covering the slat core material 10 with a sheet material 21 such as vinyl chloride or polyester film and heat-sealing the sheet material. This is plate 1
