Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rubber ring for personal use and a method for manufacturing the same, and is used as, for example, a bracelet.

(Prior Art) Conventionally, this type of rubber ring has only been provided in a single color.

(Problems to be Solved by the Invention) Single-colored rubber rings are difficult to meet various decorative needs. The variety of decorations is solely due to the ingenuity of the user, such as simply wearing multiple rubber rings of different colors at the same time, or twisting the rubber rings together at the same time, and there has not been much variation.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is characterized in that a number of rubber collar rings are embedded in a see-through rubber outer ring. In addition, it is possible to use a combination of different colored parts divided into several parts in the circumferential direction,
They do not have to be integrally connected by themselves, although they are embedded in the outer ring.

Further, a plurality of color rings may be buried in parallel or twisted together.

Furthermore, the present invention vulcanizes and molds an outer ring base made of rubber in which the annular holding groove of the collar ring opens on the outer surface, inserts the collar ring into the annular holding groove of the outer ring base, and then inserts the collar ring into the annular holding groove of the outer ring base. Another feature is that a collar ring cover part is extended and integrated into the exposed part of the collar ring by molding an unvulcanized rubber material.

(Function) The outer ring embeds and holds a number of colored rings in any suitable state, such as in an independent state or in a combined state, and is buried in an appropriate state to create its own decorative appearance that is transparent as a whole. The transparent appearance of the coloring works together to create a unique decorative effect. This unique decorativeness can be varied in various ways depending on how the color ring is embedded in the outer ring. This change can also be achieved by coloring or changing the surface shape of the outer ring to the extent that it does not impede internal visibility.

In addition, when molding involves embedding a collar ring, the outer ring base in which the annular holding groove of the collar ring opens on the outer surface is vulcanized and molded in advance, and the collar ring is inserted into the groove to create an appropriate state. The collar ring can be securely held in the desired burial position.By molding an unvulcanized rubber material to extend and integrate the collar ring cover part into the exposed part of the collar ring of the outer ring base, the outer ring The base body and the color ring cover realize an outer ring without a boundary surface in which a color ring in an appropriate state is embedded in a predetermined position.

(Embodiment) In an embodiment of the present invention shown in FIGS. 1 and 2, one silicone rubber collar ring 1 is embedded in a transparent silicone rubber outer ring 2. Both the collar ring 1 and the outer ring 2 have circular cross sections, and the collar ring 1 is embedded in the center of the outer ring 2. The color ring 1 is equally divided into four parts around the circumference, and the ring parts 1a, lb, lc, and 1d of different colors are assembled in the length direction to form one color ring 1.

Since the collar ring 1 and the outer ring 2 are made of the same material, they expand, contract, and deform as if they were a single piece. In particular, since each ring 1.2 is made of silicone rubber, it has the advantage of having a good surface gloss and not causing any rash or sagging even when it comes in contact with human skin. It is also highly elastic, heat resistant, and durable.

Further, the color ring 1 may be made by combining different colors on the inner circumferential side and the outer circumferential side, or on both the left and right sides.

FIGS. 3 and 4 show one method for making the parts shown in FIGS. 1 and 2 M-shaped. First, as shown in FIG.
Vulcanization molding is performed. Next, the mold 3 on the groove 2a side is removed, and the collar ring 1 is fitted into the opened groove 2a. The groove 2a is formed to be slightly larger than the half of the perfect circular cross section, so that the collar ring 1 can be held in a true -NR manner.
1 is the different-colored ring portions 1a, lb, and IC11dfc arranged in the length direction, so that they will not fall off even if they are not connected to each other.

With the collar ring fitted into the groove 2a, the final mold 5 is fitted to the mold 4, and an unvulcanized material is placed in the cavity 6 formed between the mold 5 and the outer ring base 2C with the collar ring 1 attached. A silicone rubber material 7 is injected and molded, and the rubber material 7 is integrated with the outer ring base 2C without any boundary surface, and is used as a collar ring cover part 2d extending over the collar ring exposed part of the outer ring base 2C. As shown in FIGS. 1 and 2, one collar ring 1 forms an outer ring 2 embedded in the center.

To obtain the color ring 1, which is a combination of different color ring portions 1a, 1b, and IC21d, as shown in FIG. By cutting them and using them in various combinations, you can eliminate the problem of parts being too long or too short.

In another embodiment shown in FIGS. 6 and 7, two silicone rubber collar rings 1 are embedded in both edges of a transparent silicone rubber outer ring 22 with an oval cross section. . In the case of this embodiment, the decorativeness increases as the number of buried color rings 1 increases, and the number of decorative aspects that can be obtained by different combinations of the color parts of the color rings 1 increases. This shows one method for manufacturing the products shown in FIGS. 6 and 7. First, as seen in FIG.
, 22b, and mold 23.2.
Vulcanization molding according to 4.25. Next, grooves 22a, 22
Remove the molds 23 and 24 facing a and open the tI22a
, 22a to fit the color ring I. After that, the final molding mold 26.27 is fitted to the mold 25, and an unvulcanized silicone rubber material is filled into the cavity 28.29 formed between the mold 26.27 and the outer ring base 22c with the collar ring 1 attached. 30 is injected and molded, and the rubber material 30 is integrated with the outer ring base 22c without any boundary surface, and is extended to the collar ring exposed portions on both sides of the outer ring base 22c.
2d, and as shown in FIGS. 6 and 7, an outer ring 22 is formed in which two collar rings 1 are embedded in both sides.

(Effects of the Invention) According to the present invention, the outer ring can embed and hold a number of colored rings in any suitable state, that is, in an independent state or in a twisted state, and can have its own decorative appearance that is transparent throughout. In addition, since the one-view appearance of the coloring embedded in an appropriate state has a complex effect, unique decorative properties can be obtained in a wide variety of ways.

In addition, in the molding process that involves embedding the collar of the outer ring, the outer ring base in which the annular holding groove of the collar is open to the outside is vulcanized and molded in advance, the collar is inserted into the groove, and the collar is placed in an appropriate state. The ring can be firmly held in the desired burial position, and the collar ring cover part is extended and integrated with the collar ring exposed part of the outer ring base by molding an unvulcanized rubber material. The ring cover part realizes an outer ring with a color ring embedded in an appropriate state at a predetermined position and without a boundary surface and which does not spoil the appearance.
