Abstract

PURPOSE:To outwardly see materials having 8 different tone by integrally forming projections spirally on the peripheral surface of linear base material, winding wire rods having the different tone from the base material on spiral recessed parts between the spiral projections and press-contacting these. CONSTITUTION:The projections 11 are integrally formed spirally at specified pitches on the peripheral surface of the base material 10 and the materials 13 having the different tone from the base material 10 are wound on the spiral recessed parts 12 between the spiral projections 11 and drawn, wire drawn and press-contacted. Accordingly, in the material for the personal ornaments with such constitution, external appearance of the materials having the different tone can be seen outwardly even if it is not cut and the materials having the different tone can be also seen on the end face and cut face and it has coloring and the material itself is excellent in ornamentation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a material for jewelry, and more particularly, to an improvement in a material for jewelry having a plurality of different hues.

(Prior Art) Conventionally, one of the materials for accessories that has a plurality of different colors consists of a hollow outer cylinder 1 and a core material 2 inserted and fixed in the outer cylinder 1, as shown in FIG. -1( Prior art documents and (7)
(No. 166512) (Problem to be Solved by the Invention) By the way, in the material for accessories listed in F, the outer appearance of the core material 2 is similar to that of the end surface 3.
It can only be seen on the cut surface 4, and if you dare to see it, you have to cut the outer cylinder l. Therefore, as a material for jewelry, it lacks color and lacks decorative properties. In addition, it is not possible to express different hues without cutting the outer cylinder 1, so adding it is necessary. Otherwise, scrap will occur. Therefore, the yield of materials is poor (and it takes time to collect scraps).

Therefore, the present invention provides a material for accessories that has a variety of colors in which the appearance of the material in different colors can be seen on the outer peripheral surface, and can also be seen on the end surface and cut surface, and the material itself has excellent decorative properties. This is what we are trying to provide.

(Means for Solving the Problems) In order to solve the above problems, the material for accessories of the present invention has a spiral protrusion integrally formed on the outer peripheral surface of a linear base material,
At least one wire made of a material of a different color from the base material described in item 1iir is wound and pressure-welded in the spiral recess between the spiral protrusions.

In the material for accessories of the present invention configured as shown in L, the appearance of materials of different colors can be seen on the outer peripheral surface without cutting, and of course, it can also be seen on the end and cut surfaces. It comes in a variety of colors, and the material itself has excellent decorative properties. Therefore, it is possible to express a colored pattern even by bending the material without applying various types of ink, making it possible to easily create jewelry, and to avoid producing scraps. As a result, the yield of materials is the same, and the collection of scrap is reduced (it takes less time).

(Example) Examples of the material for accessories of the present invention will be described with reference to FIG. 1. Diameter: 8 mm, K18 (Au75%).

A protrusion 11 having a height of 2 mrn and a width of 2 mrn is formed on the outer peripheral surface of a base material 10 made of
is integrally formed in a spiral shape with a pitch of 4 mm, and the four spiral parts 12 between the spiral protrusions 11 are provided with the base month 1 of IIf.
0 and a different color a material, e.g. P -P d ll
A wire rod 13 having a rectangular cross section of 2 mm on each side is wound, drawn, and drawn, and is in contact with jl.

FIG. 2 (Another embodiment of the jewelry material shown is 8I
Six protrusions 11 each having a height of 2 mm and a width of 2 mm are formed on the outer peripheral surface of a base material 10 made of 11nl of PtPd1.09o.
mm L niche is integrally formed in a spiral shape, and in the spiral recess 12 between the spiral protrusions 11, two types of materials with different hues from the face-engraving base material IO, for example, K 1.8 (A
u 75%-Ag12.5%-01 mouth 2. A wire rod 14 with a rectangular cross section of 2 mm on each side and made of white gold (75% Au-3.5% Cu-3.5% Zn, 5%
-N i 1.6.5. %) with a rectangular cross section of 2 mm on each side are wound in a row, and a draw ink 1. The wire has been drawn and pressure welded. 1. With the jewelry materials of each of the embodiments constructed as described above, the appearance of materials of different colors can be formed on the outer peripheral surface without cutting, and of course, as shown in FIG. 3 and FIG. Different colors of the material can be seen on the cut surface, and the material itself has excellent decorative properties. Therefore, color patterns can be easily created by simply bending the material (11) without applying various types of cutting and/or cutting, and it is possible to easily create jewelry without creating scraps. The yield of materials is improved, the amount of scrap collected is reduced, and the effort required is reduced accordingly.

In addition, the examples described above are cases in which one wire rod 13 is wound around the four spiral parts 12 on the outer periphery of the base material 0, and cases in which two wire rods 14 and 15 are wound around the outer circumference, but the invention is not limited to this. , three trees may be surrounded. Furthermore, the number of spiral recesses 12 is not limited to one, but two may be formed, and one or more wire rods may be wound and pressure-welded around each recess 12.

In this way, a material with excellent layer decoration properties is obtained.

(Effects of the Invention) As described in Section 2 below, the material for accessories of the present invention has excellent decorative properties, as materials of different colors can be seen on the outer circumferential surface, and can also be seen on the end and cut surfaces. It is possible to express color patterns by bending without performing various cutting operations, and it is possible to easily create accessories, and it is possible to prevent scraps from being generated.
Improved material yield and less scrap collection.
So, it doesn't take that much time.
