Abstract

PURPOSE:To extremely readily obtain a three-dimensional decorative flower made of rubber providing petal having funnel-shaped opening by superposing plural, circular and thin pieces made of rubber capable of freely expanding and contracting, applying a radial pressing part to the pierces and detaching the radial pressing part. CONSTITUTION:For example, plural rubber thin pieces 1 having 0.5mm thickness and having 12 curved edges on the periphery and having attaching holes bored in the center are superposed. A pressurizing body A having projection part and radially arranged in proper intervals from the center is pressed to the rubber thin pieces so as to fit position of the center of the pressurizing body A with position of the center of the rubber thin piece 1 and pressurizing part 2 extending to periphery is formed in superposed rubber thin pieces 1. Then pressurizing part 2 is detached while leaving central part of the rubber thin pieces 1 and petal 4 having funnel opening 3 is provided to afford the decorative flower mode of rubber.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a three-dimensional decorative rubber flower, which allows petals with funnel-shaped openings to be formed very easily.

[Prior Art] Traditionally, decorative flowers used to decorate swim caps and the like are made by overlapping multiple synthetic resin molded sheets each having a plurality of petals separated radially from the center, and then applying adhesive, heat-sealing, or Using high-frequency waves, etc., superimposed synthetic resin molded sheets are glued together at the center, and a plurality of radially separated petals are raised to give a three-dimensional effect.

[Problem to be Solved by the Invention] However, in the method for manufacturing a decorative flower according to the above-mentioned prior art, a sheet made of synthetic resin such as vinyl chloride is made into a flower shape having a plurality of petals separated radially from the center. The synthetic resin molded sheets are overlapped to form a medium 8
Because it is manufactured by adhering parts by heat-sealing, etc., when molding a flower-shaped synthetic resin sheet, a special method is used that can be separated radially from the center in order to mold multiple petals. It requires a mold, which is costly, and in order to give it a three-dimensional effect, multiple flower-shaped synthetic resin sheets must be stacked and glued in the center, and then each petal needs to stand up, making it time-consuming to manufacture. Furthermore, there is a problem in that the raised petals return to a flat state over time and lose their three-dimensional appearance.

The present invention eliminates the drawbacks of the above-mentioned prior art,
Simply overlap multiple circular elastic rubber strips, create radial crimped parts, and then separate the crimped parts.
The present invention provides a method for manufacturing a rubber decorative flower in which a decorative flower having three-dimensional petals is formed.

[Means for Solving the Problems] To summarize the present invention, it relates to a method for producing a decorative flower made of rubber that can extremely easily form a decorative flower having three-dimensional petals. After stacking a plurality of sheets of (1), a pressing body (A) having projections arranged radially at appropriate intervals from the center is placed between the center of the pressing body (A) and the center of the rubber thin piece (1). A radial crimp part (2) extending to the outer periphery is formed on the rubber flake (1) to be polymerized by pressing the rubber flake (1) so that the position of the rubber flake (1) matches. ) is characterized in that a large number of petals (4) having funnel-shaped openings (3) are provided by cutting them apart.

[Function] The present invention has the above-mentioned configuration, in which a plurality of circular elastic rubber flakes (1) are stacked one on top of the other, and then protrusions are arranged radially from the center at appropriate intervals. The press-contact body (A) is connected to the center of the press-contact body (A) and the rubber thin piece (1).
When pressed so that the center of the body matches the center of the body, the body (
Crimping portions (2) are formed at radial portions of the rubber thin piece (1) that are in contact with the projections of A). When the crimp part (2) is formed, the protrusion of the press-fitting body (A) is press-fitted into the rubber thin piece (1), so that the rubber thin piece (1) is stretched by the amount that the protrusion is press-fitted. In addition, frictional heat is generated due to press-fitting of the protrusion of the pressure-welding body (A), and by appropriately heating the protrusion in advance, the pressure-bonding part of the polymerized rubber flake (1) (
2) becomes a fused state.

Next, when each crimping part (2) provided radially is cut off leaving the central part of the rubber flake (1), the rubber flakes (1) that overlap above and below are separated into a plurality of pieces while being connected at the cut-off part. The rubber flakes (4) are formed as described above.
In 1), since the crimp part (2) is provided in a state where the protrusion of the crimp body (A) is stretched by the amount that is pressed in, each petal (4) is The polymerized rubber flakes (1) constituting each curve outwardly, and the petals (4) have funnel-shaped openings (3);
A decorative flower with a three-dimensional effect is formed overall.

[Example] Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows a circular rubber flake (1),
An elastic natural or synthetic rubber material with a thickness of about 0.5 mm is used, and in this example, in order to give a more decorative effect, 12 curved edges are placed at equal intervals around the outer circumference of the circle. A mounting hole is drilled in the center for mounting on the object to be decorated.

Next, as shown in Figure 2, two rubber thin pieces (1) of different colors are attached.
After stacking the sheets, place them in a cylindrical shape on the bottom 6 points from the center of the bottom.
A pressure contact body (A) having protrusions arranged radially at intervals of 0° (indicated by dots in the upper part of FIG. 2) is placed so that the center of the pressure contact body (A) and the center of the rubber thin piece (1) are aligned. By applying appropriate pressure to suitably polymerized rubber thin pieces (1) and applying heat as necessary, they are placed at six locations at 60° intervals as shown in Figure 3. A radial crimp portion (2) is formed.

Next, as shown in Fig. 4, when the crimped part (2) is cut off leaving the central part of the rubber thin piece (1), a decorative rubber flower with six petals (4) and a funnel-shaped opening (3) is formed. form.

To separate the crimp part (2), make the protrusion of the crimp body (A) into a convex shape with an acute tip, and press the protrusion into the rubber flake (1) that overlaps when the protrusion is press-fitted with pressure greater than the window. The separation may be performed by creating a cut.

Moreover, if the decorative rubber flowers of different sizes produced by the method of the present invention are stacked concentrically, the decorative effect will be further enhanced.

[Effects of invention According to the present invention having the above configuration, the following effects are achieved.

By stacking multiple simple circular rubber thin pieces (1) to form a crimped part (2) and cutting the crimped part (2) leaving the center, a funnel-shaped opening (3) can be created naturally. The petal (4) having the structure is formed, and as in the prior art,
In order to give a three-dimensional effect, several flower-shaped synthetic resin sheets are overlapped and glued together in the center, which eliminates the need for each petal to stand up, and furthermore, the upturned petals become flat due to use over time. This eliminates the inconvenience of losing the three-dimensional effect, and it becomes possible to extremely easily produce decorative flowers that have a three-dimensional effect for a long period of time.
