Description

[Detailed Description of the Invention] The present invention relates to a simple structure of a bead on the epidermis that is heated and fused to the epidermis.

Beads on the skin are often used as reinforcement, accents, or decoration by interposing them in the seams of seats or bags.

In FIGS. 1 and 2 showing examples of conventional beaded skin, numerals 1, 1a, and 1b are the skin, 2 is wading made of, for example, a thin urethane foam material, and 3 is
1 is the back base fabric, which is shown with the outer skins 1, 1a, and 1b facing down for reference in relation to the fusion method described later. 4
The ball is shaped like a ball and is connected to a ball core 4a and a ball-shaped skin 4b.

In Fig. 1, a ball core 4 (commercially available) is interposed between one skin 1a and the other skin 1b, and sewn along the dotted line, and in Fig. 2, a ball core 4a is interposed between the skin 1 and the other skin 1b. This is a conventional example in which the ball core 4a is heated on both sides, for example by high frequency, and pressed and fused to form a ball core 4a with a ball-shaped skin 4b placed on top of the ball core 4b.

In the embodiment shown in Fig. 1, both ends are overlapped and sewn together, so the seam is thick, and the end is on the back base fabric 3 side, so when used as an outer layer, it feels like a foreign body and when used, it is raised. The finish is poor, and in FIG. 2, the protruding portions 4c of the bead skin 4b are exposed on both sides of the bead 4, which has an unfavorable appearance.

The present invention was devised in view of the drawbacks of the conventional examples, and aims to provide a beautiful beaded skin at a low cost with a simple structure.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, for reference, an example of the apparatus and manufacturing method for welding the beveled skin of the present invention will be briefly explained with reference to FIGS. 3 and 4. In the figure, the same parts as in the conventional example are given the same reference numerals.

In the figure, 7 is a high-frequency upper mold, and 8 is a high-frequency lower mold. On this high-frequency upper mold 8, there is a protrusion part 8b which is elongated by the length of the bead 4 and has a rectangular cross section, and on both sides above it, the bead 4 and Presser welding molds 9a and 9b having an L-shaped cross section and having approximately the same length are symmetrically mounted in elongated holes 11 by pins 12 so as to be movable up and down, and a spring 10 is elastically loaded between the lower part and the lower mold 8. has been
A gap 9c is formed between the presser welding molds 9a and 9b above the protrusion 8b.

Prior to fusion molding, the ball-shaped skin 4b is inserted into the gap 9c in a U-shape, the ball core 4a is inserted, and the skin 1 is waded with the back base fabric 3 facing up between it and the high-frequency upper mold 7. Install them in order.

Next, as shown in FIG. 4, when the high-frequency upper mold 7 is lowered downward, the presser welding molds 9a and 9b are also pushed downward to some extent, and the wrapped portions 4d on both sides of the beaded skin 4b are also pushed down from above. Therefore, as the height of the gap 9c becomes lower, the winding portion 4d winds up on both sides of the ball core 4a. High frequency upper mold 7
When the presser welding molds 9a, 9b are further lowered and the winding part 4d wraps up the ball core 4a as shown in FIG. , the bead 4, the outer skin 1, the wadding 2, and the back base fabric 3 are fused together. In this case, the outer skin 1, wading 2, and back base fabric 3 that are in contact with the upper part of the presser foot welding molds 9a and 9b are fused wider than the width of the upper ends of the presser foot welding molds 9a and 9b, so that both wrapping parts 4d is fused to the epidermis 1.

The first part of the epidermis ball 4 completed in this way
An example is shown in FIG.

Figure 6 shows the second embodiment, with an epidermis 1a and another epidermis 1b.
(If the fabrics are different, the colors may be different, or the fabric may be the same) are overlapped at the end, and the ball core 4a is wrapped around the ball core 4b in the same manner as described above, and the ball core 4 is wrapped. This is an example of fusion molding.

FIG. 7 shows a third embodiment, in which the beaded outer skin 4b is not used, and the end of the outer skin 1b is used instead to wrap around the ball core 4a, and the beaded outer skin 4 is fusion-molded.

The fourth embodiment shown in FIG. 8 does not use the ball core 4a shown in FIG. 5, but rolls up the ball-shaped skin 4b to form a roughly ball-shaped shape. Use this when you want a flat ball shape with no feel. The inner space may not come out as shown.

Fig. 9 shows an example in which the beaded skin 4b of Fig. 8 is widened and rolled up twice, or even tripled, and fused and molded against the skin 1 without the bead core 4a. It is used when there is little space and a certain degree of hardness is required.

The embodiment shown in FIG. 10 is the ball core 4a of the embodiment shown in FIG.
In this embodiment, the end portions may be doubled or tripled as described above.

FIG. 11 shows a case where, for example, vinyl leather or a hard knitted fabric is used for the ball core skin 4b shown in FIG. 5, and both ends of the ball core skin 4b are folded and rolled up.

This is because when the wrapped portion 4d in Fig. 3 is pressed from above and the skin material is harder than a fabric such as vinyl leather, both upper ends of 4d bend inward, resulting in the shape of the cross section shown in Fig. 11. Become.

Figure 12 shows a case in which a decorative stripe of vinyl leather is fused to the surface of the knitted skin (when a wide tape-like material with a ball core skin 4b is used and there is no ball core 4a), and both ends are the same as in Figure 11. It has a folded and rolled shape.

When the skin bead of the present invention as described above is adopted, the number of man-hours is reduced, so costs can be reduced, and it is possible to obtain a bead with a beautiful finish.
