Abstract

<P>PROBLEM TO BE SOLVED: To provide a decoration such as an emblem or the like having rich stereoscopic feeling. <P>SOLUTION: A method for manufacturing a bulged decoration comprises the steps of forming a bulged structure 20 having a large-sized bulged part 18 made of a synthetic resin sheet, separating the bulged part 18 of the large- sized structure 20 into a plurality of small-sized bulged parts 4 by hot pressing, and thereby manufacturing the bulged decoration. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a swollen decorative body such as an emblem or a sticker. 2. Description of the Related Art Clothing and hats have been enhanced in design by attaching, for example, patches. There is a three-dimensional thing with a bulge as this kind of emblem. [0003] However, the conventional product has a problem that the bulge is not so large and the three-dimensional appearance is poor. Further, each bulge is formed by air injection or the like. Manufacturing efficiency was not good either. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a decorative body such as an emblem with a rich three-dimensional effect easily. According to the present invention, a swelling structure having a large swelling portion made of a synthetic resin sheet is formed, and a plurality of swelling portions of the large swelling structure are formed by hot pressing. A swelling decorative body is manufactured so as to be separated into small swelling portions. According to the above-mentioned manufacturing method, a large number of swelling decorative bodies can be obtained from a large swelling structure by one-step hot pressing, so that the manufacturing efficiency is excellent. In addition, when a large bulge is separated into a plurality of small bulges by hot press processing, air is pushed into each of the small bulges, so that the bulge is large and excellent in three-dimensional design. A swelling decorative body is obtained. FIG. 1 is a perspective view of a decorative body 1 including a cutaway section. Reference numeral 2 denotes a substrate made of cloth or the like, and on its upper surface, an English character pattern pattern 3 made of a PVC sheet
Is fixed, and a surface material 5 made of a transparent urethane sheet has an upward bulging shape on the pattern 3 so that a space (small bulging portion) 4 is formed between the surface material 5 and the pattern 3.
The periphery is fixedly attached to the periphery of the pattern 3 so as to have As the surface material 5, a material having a fine uneven pattern 7 formed on the surface is used, and the surface is diffusely reflected to shine. Hereinafter, a method of manufacturing the decorative body 1 will be described with reference to the drawings. [First Step] As shown in FIG. 2, a surface of an insulating plate 1 is placed on a mold base 13 serving as one electrode.
4, a metal frame 16 provided with an opening 12 is provided. The urethane sheet 15 and the vinyl chloride sheet 11 are placed on the opening 12 in an overlapping state. A double-sided tape 17 is adhered on the third surface of the mold, which is the bottom of the opening 12, and the urethane sheet 15 is disposed in the opening 12 so as to be bent downward in the opening 12 by being adhered to the double-sided tape 17. Then, both peripheral edges of each of the sheets 15 and 11 positioned in a state of being overlapped on the upper edge of the opening 12 of the metal frame 16 are pressed by a pressing mold 19 which is the other electrode, and high-frequency dielectric heating is performed. As a result, a sheet body (bulging structure) 20 having an air layer (large bulging portion) 18 as shown in FIG. 3 is obtained. [0010] As shown in FIG.
A cloth body 21 for forming is placed, the sheet body 20 obtained in the first step is placed on the upper part thereof, and pressed from above by a pressing and cutting mold 22 serving as the other electrode,
Performs high-frequency dielectric heating (hot pressing). As shown in FIG. 5, the pressing and cutting die 22 has a cutting part 23 having cutting teeth 24 on the outside and a holding part 25 on the inside, as shown in FIG. 5.
First, each of the sheets 11 and 15 is cut so that the cutting blade 24 leaves a pattern portion by lowering the mold 22 to a predetermined position shown in FIG. Then, at that position, the holding portion 25
1. High-frequency dielectric heating is performed in a state where the peripheral edge of the sheet 15 and further the cloth body 21 are overlapped and held down, and they are integrally fixed. As a result, as shown in FIG.
The decorative body 1 having the space 4 between the and the pattern 3 is obtained. In particular, since the space 4 is formed in the first step so that the urethane sheet 15 is curved downward in the opening 12 by sticking to the double-sided tape 17, the bulge is large. Is three-dimensional and has excellent design. The decorative body 1 is used with the surface of the substrate 2 attached to clothes or the like.
Can be directly implemented as clothes or the like. According to the present invention, a decorative body such as an emblem or a sticker having a large swelling and excellent three-dimensionality can be easily manufactured.
