Description

[Technical field]

[0001] The present invention relates to a method for manufacturing a pierced earring and an ear accessory. [Background technology]

[0002] Conventionally, known types of earrings include those in which the post and back are separate (see, for example, Patent Document 1) and those in the shape of a hoop in which the post is connected to the main body of the earring via a hinge (see, for example, Patent Document 2).

[0003] FIG. 3 is a plan view showing a schematic configuration of a conventional hinged hoop earring.

[0004] The hinged hoop earring 91 includes an earring body 92, a post 93, a hinge 94, and a catch 95. The earring body 92 has a shape in which a part of a ring shape is cut out. The hinge 94 is attached to one end of the cutout of the earring body 92, and the catch 95 is attached to the other end of the cutout. One end of the post 93 is attached to the hinge 94 so as to be rotatable around the axis of the hinge 94. The upper surface of the catch 95 is provided with a groove (not shown) that extends in the left-right direction in FIG. 3 and into which the vicinity of the other end of the post 93 can be fitted. The width of the entrance of the groove provided in the catch 95 is set to be larger than the width of the post 93, and when the vicinity of the other end of the post 93 is fitted into the groove of the catch 95 or when the post 93 is removed from the groove of the catch 95, the post 93 passes through the entrance of the groove while pushing apart the opposing wall of the catch 95. When the vicinity of the other end of post 93 is fitted into the groove of catch 95 (as shown in Figure 3), the vicinity of the other end of post 93 is locked to catch 95, and the piercing body 92 and post 93 form a hoop.

[0005] When in use, the other end of post 93 is pushed up in the direction of the arrow in the figure to remove it from the groove of catch 95, post 93 is inserted into the piercing hole in the earlobe, and then the vicinity of the other end of post 93 is again fitted into the groove of catch 95, thereby allowing hinged hoop earring 91 to be attached to the ear.

[0006] [Patent Document 1] JP 2020-092900 A [Patent Document 2] Registered Utility Model No. 3152978 Summary of the Invention [Problem to be solved by the invention]

[0007] As described above, when the hinged hoop earring 91 shown in Fig. 3 is used, when the post 93 is fitted into the groove of the catch 95, or when the post 93 and the catch 95 are released from each other, the groove of the catch 95 is pushed open by the post 93. When the number of times of use is small, the groove of the catch 95 is pushed open and then returns to its original state. However, as the number of times the post 93 is engaged and released from the catch 95 increases, the gap between the grooves of the catch 95 gradually increases, and the holding force of the post 93 when it is engaged with the catch 95 decreases.

[0008] Therefore, an object of the present invention is to provide a method for manufacturing piercings and ear accessories in which the retention force of the post by the catch is prevented from decreasing even when the post and catch are repeatedly engaged and disengaged. [Means for solving the problem]

[0009] The piercing according to the present invention comprises a piercing body having a shape with a part of the ring cut out, a post rotatably connected to one end of the piercing body via a hinge, and a catch provided at the other end of the piercing body and having a groove into which a part of the post can be fitted, Beryllium Copper or Phosphor Bronze It consists of:

[0010] The method for manufacturing the above-mentioned pierced earrings according to the present invention comprises the steps of: Beryllium Copper or Phosphor Bronzeand using a mold to mold the earring body and catch; melting any of stainless steel, titanium, beryllium copper, phosphor bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950, and platinum 999 and using a mold to mold the post; and attaching the post to the earring body via a shaft. Effect of the Invention

[0011] According to the present invention, it is possible to provide a method for manufacturing a piercing or an ear accessory in which the retention force of the post by the catch is prevented from decreasing even when the post and catch are repeatedly engaged and disengaged. [Brief description of the drawings]

[0012] [Figure 1] FIG. 1 is a plan view showing a schematic configuration of a pierce according to an embodiment; [Diagram 2] Cross-sectional view taken along line II-II in Figure 1. [Diagram 3] FIG. 1 is a plan view showing a schematic configuration of a conventional hinged hoop earring. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] FIG. 1 is a plan view showing a schematic configuration of a pierce according to an embodiment, and FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG.

[0014] The earring 1 is a hinged hoop earring comprising an earring body 2, a post 3, and a catch 5. The earring body 2 has a ring shape with a portion cut out. One end of the post 3 is rotatably connected to one end of the cutout of the earring body 2 via a hinge 4. A catch 95 is provided at the other end of the cutout of the earring body 2.

[0015] As shown in Fig. 2, the catch 5 has a groove 6 into which a portion of the post 3 near the other end can be fitted. The width of the entrance portion of the groove 6 is set smaller than the width of the post 3. Therefore, as shown in Fig. 2, when the post 3 is fitted into the groove of the catch 5, the post 3 is held and locked between the opposing walls 7a and 7b of the catch 5.

[0016] When using the earrings, the tip of the post 3 is pushed upward in Figs. 1 and 2 to remove the post 3 from the groove 6 of the catch 5, and the post 3 is inserted into the piercing hole of the earlobe, and then the post 3 is fitted into the groove 6 of the catch 5 again, so that the earrings 1 can be attached to the ear. In the process of removing the post 3 from the groove 6 of the catch 5 and in the process of fitting the post 3 into the groove 6 of the catch 5, when the post 3 passes through the entrance part of the groove 6 (part narrower than the width of the post 3), the opposing walls 7a and 7b of the catch 5 are pushed outward by the post 3. Conventionally, the catch part has been formed using a general metal material for earrings, such as brass or iron. In this case, there was a problem that the width of the groove 6 gradually widens when the post 3 is repeatedly fitted and released, and the holding force of the post 3 when it is fitted into the catch 5 is easily reduced.

[0017] In this embodiment, among the pierced earring body 2, the post 3, and the catch 5, at least the catch 5 is made of any one of the following metal materials: stainless steel, titanium, beryllium copper, phosphor bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950, and platinum 999. Beryllium copper is an alloy in which 0.5 to 3% beryllium is added to copper, but it may also be an alloy containing other metals such as nickel and cobalt. Phosphor bronze is an alloy containing copper, tin, and phosphorus. Silver 925 and silver 950 are precious metals with silver purities of 92.5% and 95.0%, respectively, and contain copper, nickel, cobalt, aluminum, and the like as metals other than silver. Silver 1000 is silver with a purity of 100%. 10K, 14K, and 18K are precious metals with gold purity of 10 / 24, 14 / 24, and 18 / 24, respectively, and contain other metals such as silver, copper, palladium, nickel, and zinc. White gold and pink gold are yellow gold with different colors depending on the content of metals other than gold. Platinum 850, Platinum 900, Platinum 950, and Platinum 999 are precious metals with platinum purity of 85.00%, 90.00%, 95.00%, and 99.95%, respectively, and contain other metals such as silver, palladium, nickel, and ruthenium.

[0018] Stainless steel, titanium, beryllium copper, phosphorus bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950 and platinum 999 are all hard and have high strength. Therefore, by forming the catch 5 of the earring 1 with any of these metal materials, even if the post 3 is repeatedly engaged and disengaged, the groove 6 of the catch 5 can be suppressed from widening, and the holding force of the post 3 in the state in which the post 3 is engaged with the catch 5 can be maintained for a longer period of time. In addition, since the above-mentioned metal materials have high strength, the holding force of the post 3 can be secured even if the walls 7a and 7b of the catch 5 are thinned or the catch 5 is made small. Therefore, the design of the earring 1 can be improved by thinning the walls 7a and 7b of the catch 5 and / or by making the catch 5 small.

[0019] Both the piercing body 2 and the catch 5 may be integrally formed from the same metal material. Here, integral formation means that the piercing body 2 and the catch 5 are not made as separate parts and are formed seamlessly by casting or the like. In the conventional hinge-type hoop piercing as shown in FIG. 3, the catch part and the piercing body are generally formed as separate parts and joined by welding or the like. In contrast, when the piercing body 2 and the catch 5 are integrally formed from the same metal material, the process of attaching the catch to the piercing body by welding is not required, so that the manufacturing cost can be reduced. In addition, by continuously forming the piercing body 2 and the catch 5 by integral molding, a sense of unity between the piercing body 2 and the catch 5 is created compared to the case of connecting by welding as shown in FIG. 3, so that the design can be improved. As a method of integrally forming the piercing body 2 and the catch 5 from the same metal material, for example, casting can be adopted.

[0020] The post 3 may be formed from the same metal material as the piercing body 2 and the catch 5, or may be formed from a different metal material than the piercing body 2 and the catch 5. If the post 3 is formed from the same metal material as the piercing body 2 and the catch 5, the strength of the post 3 is improved, so that even if the post 3 is repeatedly engaged and disengaged, deformation of the post 3 can be suppressed, improving the durability of the piercing 1. Furthermore, if the piercing body 2, the catch 5, and the post 3 are formed from the same metal material, the texture of the piercing 1 can be unified.

[0021] In addition, post 3 can be formed from any of the following metal materials: stainless steel, titanium, beryllium copper, phosphor bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950, and platinum 999.

[0022] Beryllium copper is more preferable as the metal material used for the earrings 1. All of the above-mentioned metal materials are excellent in strength, but the parts formed of titanium cannot be plated, so the earrings 1 cannot be given a metallic luster. Stainless steel can be plated, but the plating layer is easily peeled off. Beryllium copper is particularly strong, can be provided with a plating layer on the outermost surface, and has good durability, making it a more preferable material for the earrings 1, which is an ornament.

[0023] The material of the plating layer provided on the outermost surface of the earring 1 is not particularly limited, but gold, silver, copper, platinum, rhodium, chromium, tin, tin-cobalt alloy, zinc, nickel, etc. can be used.

[0024] In the earring 1 according to this embodiment, when a part of the post 3 is fitted into the groove 6 of the catch 5, the outer surface of the earring body 2 and the outer surface of the post 3 are connected by a continuous curved surface, forming a ring shape consisting of a continuous curve around almost the entire circumference of the earring 1. By smoothly connecting the vicinity of the connection part between the earring body 2 and the post 3 with a continuous curved surface, a sense of unity between the post 3 and the earring body 2 is created, resulting in excellent design.

[0025] The earrings 1 according to the present embodiment can be manufactured by melting a metal material consisting of any one of stainless steel, titanium, beryllium copper, phosphor bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950, and platinum 999, molding the melted metal material using a mold to form the earring body 2, the catch 5, and the post 3, and attaching the post 3 to the earring body 2 via a shaft body. If necessary, a step of polishing the parts after the casting may be provided. In addition, when a plating layer is provided on the outermost surface, a step of plating treatment by a known method may be provided on the parts after the casting or the surface of the earrings 1 after assembly.

[0026] The manufacturing method according to the present embodiment can also be applied to the manufacture of ear accessories other than pierced earrings, such as earrings and ear cuffs. That is, ear accessories can be manufactured by melting a metal material made of any of stainless steel, titanium, beryllium copper, phosphor bronze, silver 925, silver 950, silver 1000, 10K gold, 14K gold, 18K gold, 10K white gold, 14K white gold, 18K white gold, 10K pink gold, 14K pink gold, 18K pink gold, platinum 850, platinum 900, platinum 950, and platinum 999, and molding the molten metal material using a mold to form a part or the whole of the ear accessory. When manufacturing an ear accessory made of multiple parts such as earrings, a process of assembling the parts is performed after a process of casting the parts. Similarly, a process of polishing the parts after casting may be provided as necessary. A process of plating the surface of the parts after casting or the surface of the pierced earrings 1 after assembly may be provided by a known method. Earrings and ear cuffs have a retaining part that holds the earlobe when worn on the ear. When earrings, ear cuffs, and other ear accessories are cast from any of the above-mentioned metal materials, the deformation of the retaining part is suppressed even when used repeatedly, and the retaining force of the retaining part can be maintained, thereby improving the durability of the ear accessory. The entire ear accessory such as earrings or ear cuffs may be cast from any of the above-mentioned metal materials, or a part of the ear accessory including the retaining part for holding the earlobe may be cast from any of the above-mentioned metal materials.

[0027] In this embodiment, an approximately circular earring has been described as an example, however, the shape of the earring is not limited to a circle, and may be a polygon such as a triangle, a square, a pentagon, or a hexagon, or an oval, a spindle, or any other shape, and may have a shape in which a part of any shape is connected to a ring-shaped part that is worn in the ear.

[0028] Furthermore, the catch may have any shape as long as it can hold a part of the post by pinching it therebetween, and is not limited to the specific example shown in FIGS.

[0029] Also, the catch and hinge may be cast as separate parts from the piercing body, as in the conventional example shown in FIG. 3, and then attached to the piercing body by welding or the like. [Industrial Applicability]

[0030] The present invention can be used for ear accessories such as pierced earrings. [Explanation of symbols]
