Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a slat for a blind and a method for manufacturing the same.

(Prior art) Generally, in blinds, especially horizontal blinds, thin aluminum plates are used as slats.
This is used after being subjected to various coloring processes. However, with the spread of blinds in ordinary households and the rise in decorative requirements, there is a growing need for slats to be changed in color or patterned.

In order to meet these demands, proposals have been made to apply transfers to the slats or paste wallpaper, etc., but the former is impractical in terms of cost, while the latter is not practical. For example, as shown in FIG. 10, it is difficult to work with wallpapers 3 and 3 on the front and back surfaces of the slats 1, and it is also aesthetically undesirable because the slats, which are core materials, are exposed at both ends of the slats. There were many difficulties.

(Problems to be Solved) In view of the above-mentioned current situation, the present invention aims to provide a slat for blinds that is excellent in appearance, is advantageous in improving workability, and is inexpensive in terms of cost. This was done as a. Another object of the present invention is to provide a method that can effectively manufacture such slats with excellent aesthetic appearance.

(Means for Solving Problems) The gist of the present invention for achieving the above-mentioned object is to provide a slat formed by adhering a decorative sheet to a slat material (hereinafter referred to as core material) such as an aluminum plate so as to wrap it around it. This decorative sheet has a width dimension that is approximately twice as long as the core material, and the seam at the end in the width direction is located approximately in the center of one side of the core material. There are slats for the blinds.

In the above structure, the decorative sheet may be made of a bendable sheet material such as paper, synthetic resin, woven fabric, non-woven fabric, etc. as appropriate.

Further, the gist of the manufacturing method of the present invention provided for forming such a slat includes the step of pasting a core material approximately at the center of a decorative sheet having a width approximately twice that of the core material; a step of folding the parts of the decorative sheet that protrude from both sides of the width onto the back side of the core material;
This method of manufacturing a slat for a blind comprises the steps of cutting the overlapping portions of decorative sheets bent on the back side, and pasting the cut decorative sheet on the back side of a core material.

(Example of the invention) The present invention will be explained below based on the drawings.

In FIG. 1, 1 is a slat material (core material), and an existing aluminum slat material may be used as is, or another material may be used.
2 is a decorative sheet made of paper, which is used so as to wrap around the slat material in the width direction. Figures 2A and 2B show cross-sections of the slats, with Figure 2 showing the case where the ends are overlapped, and Figure 2 showing the case when the ends are butted. The width direction seam of the decorative sheet 2 may be of any of the types shown in FIG. FIG. 3 schematically shows the appearance of a blind with a diagonal stripe pattern using the slats of the present invention (see FIG. 7). In FIG. 3, 4 indicates a head box; 5 indicates a lower plate, and 6, 6, 6 indicates a lifting cable.

Figures 4 to 7 show examples of patterns given to the slats by the decorative sheet 2, in which diagonal stripes are formed by a series of square patterns at intervals of dimension b in Figure 4. The decorative sheet 2 shown in the figure is cut at a mark 7, and the slat material 1 is pasted approximately at the center of its width. An appropriate adhesive may be used for pasting, but an adhesive may be applied to the back surface of the decorative sheet 2 in advance. Note that the width dimension 2a of one unit of the decorative sheet 2 cut along the cutting line 7 is the width dimension c of the slat material 1.
It is approximately twice as long.

Then, as shown in FIGS. 5 to 7, the width end portions of the decorative sheet are successively folded back and adhered to the back side of the slat material to form a slat 8 having a surface pattern as shown in FIG. 7.

According to such a slat, since the core material does not appear on the surface except for the ends in the longitudinal direction,
In particular, it has an aesthetically pleasing appearance as a blind, which has come to be considered as one of the interior parts, and provides excellent utility as a new type of blind slat. In particular, by using a decorative sheet, it is possible to use not only limited aesthetic improvements such as coloring, as is the case with aluminum materials, but also the ability to adopt a wide variety of patterns.

FIGS. 8 and 9 show an example of an outline of the configuration of equipment for efficiently manufacturing the slats described above, and in the figures, the slat material is wound around a roller 101 with its longitudinal direction as the winding direction. Similarly, the decorative sheet is placed on roller 102.
is wrapped in. The width of the decorative sheet 2 is slightly longer than twice the width of the slat material 1.

The slat material 1 and the decorative sheet are unwound from these rollers 101 and 102 at the same speed and sent to the next process while being overlapped by guide rolls 103 and 104. The adhesive is continuously applied by the application device 105.

The slat material and the decorative sheet overlapped by the guide rollers 103 and 104 are bent by the forming rollers 106 and 107 so that the protruding portion in the width direction is bent with respect to the slat material 1 as shown in FIG. 9B. It will be done. These forming rollers 106, 10
In this example, 7 is formed as a pair of rollers that fit into each other in a concave and convex manner, but the roller pair is not limited to this.

The stacked body on which the forming rollers 106 and 107 have been formed is cut into a predetermined length by a cutter 108, and then cut into a slat 8 as shown in FIG. is formed. During this coating process, if it is difficult to achieve exact measurement consistency between the width dimension of the decorative sheet 2 and the width dimension of the slat material 1, the steps shown in FIGS. It may be added in the middle of the process shown in the figure. This addition step is a step in which the ends of the decorative sheets 2 are overlapped with each other and the overlapping portions are cut off using a cutter.
Generally, it is preferable that this step be arranged at the front stage of the adhesive application device 109.

According to the manufacturing method described above, it is possible to form the desired slat in a fully automated manner while unwinding the slat material and the decorative sheet one after another from the rollers, and the equipment itself is relatively simple. There is a benefit of having enough.

(Effects of the Invention) As described above, according to the present invention, the decorative properties of the slats for blinds are dramatically improved compared to conventional blind slats, and the benefits are extremely large. Since it can be done easily, its usefulness is great.
