Embodiments of the present invention will be described below based on the drawings. In the following description, the same members are given the same reference numerals, and the description of the members that have been described once will be omitted as appropriate.

(Earring post and earrings)
FIG. 1 is a front view illustrating a piercing post and a piercing according to this embodiment.
FIG. 2 is an exploded front view illustrating the pierced earring post and the pierced earring according to the present embodiment.
As shown in FIGS. 1 and 2, the earring 1 according to the present embodiment includes a holding frame 10 that holds a jewelry 100, and an earring post 20 that is attached to the holding frame 10. The 100 jewelry items include jewelry such as diamonds, as well as items decorated with glass, metal, and the like. The jewelry 100 and the holding frame 10 are examples of decorations.

Jewelry 100 is held in a holding frame 10 made of metal (gold, silver, platinum, etc.), for example. The holding frame 10 has a stone seat part 11 and a claw part 12 extending from the stone seat part 11. For example, a plurality of claw parts 12 are provided, and are arranged so as to grip the outer periphery of the jewelry 100 placed on the stone seat part 11. By bending the tip portion 12a of the claw portion 12 toward the edge of the jewelry 100, the jewelry 100 is pressed from above and fixed to the holding frame 10. Light enters the jewelry 100 through the gap provided between the claw parts 12, and the jewelry 100 can shine.

The pierced earring post 20 includes a post body 21 formed of a material harder than the holding frame 10 (hereinafter sometimes referred to as "high hardness material"), and a fitting part 30 provided at one end of the post body 21. Equipped with. The high hardness material forming the piercing post 20 may be, for example, a non-metallic material such as ceramic, or a metallic material (such as an alloy) having a higher hardness than the holding frame 10. By forming the earring post 20 from a highly hard material such as ceramic that does not easily cause allergies, it becomes possible for users with allergic predispositions such as metal allergies to use the earring 1.

The post body 21 is a cylindrical member that is inserted into a piercing hole when attaching the piercing 1 to an earlobe or the like. The diameter of the post body 21 is approximately 0.6 mm to approximately 1.0 mm (typically approximately 0.8 mm). Grooves 21a and 21b into which catches (not shown) are fitted are provided on the other end side of the post body 21. In this embodiment, two grooves 21a and 21b are provided at a predetermined interval, so that the attachment position of the catch can be adjusted depending on the thickness of the attachment site such as the earlobe. Note that the number of grooves 21a and 21b is not limited to two, and may be one or three or more.

The post body 21 is fitted into the stone seat part 11 of the holding frame 10 by the fitting part 30. The post body 21 is firmly attached to the holding frame 10 by being fitted by the fitting part 30.

The fitting part 30 has a fitting part body 31 extending to one end side of the post body 21. It is preferable that a protrusion 32 that protrudes outward (in the radial direction) is provided on the distal end side of the insertion part main body 31. The protruding portion 32 has a portion that slightly protrudes in the radial direction from the outer shape of the fitting portion main body 31. For example, the fitting part main body 31 has a cylindrical shape, and the protruding part 32 has a cylindrical shape having a diameter larger than the diameter of the fitting part main body 31.

The tip of the protrusion 32 may have a curved surface (convex on the tip side). Thereby, when fitting the fitting part 30 into the holding frame 10, it becomes easier to push the tip of the protruding part 32. Further, when the fitting part 30 is fitted into the holding frame 10, the protruding part 32 is inserted while pushing and expanding the pilot hole of the holding frame 10, and after the protruding part 32 passes through the pilot hole, the protruding part 32 is inserted into the holding frame 10. ” and can prevent the piercing post 20 from coming off.

Note that the shapes of the fitting portion main body 31 and the protruding portion 32 are not limited to the cylindrical shape. For example, the fitting portion main body 31 may have a prismatic shape or a tapered shape. Further, the protrusion 32 may have a conical shape or a pyramid shape with a pointed end, or a protrusion provided on the outer circumferential surface of the insertion part main body 31 (a protrusion in which a part of the circumferential direction is a protrusion), It may have a plurality of protrusions), or it may be a portion where the outer circumferential surface of the fitting portion main body 31 is roughened.

Further, it is preferable that the fitting portion 30 is formed integrally with the post body 21 from a high hardness material such as ceramic. For example, the post body 21 and the fitting portion 30 may be integrally formed by firing ceramics or the like. As a result, the post body 21 and the fitting portion 30 are configured as one component made of a high-hardness material, so that manufacturing costs and assembly costs of the components can be reduced.

On the other end side of the post main body 21 (the side opposite to the side where the fitting part 30 is provided) from the fitting part 30, an enlarged diameter part 40 that expands outward from the fitting part 30 is provided. The expanded diameter portion 40 has a larger diameter than the insertion portion main body 31. When the fitting body 31 has a cylindrical shape, for example, the diameter of the fitting body 31 is approximately equal to that of the post body 21, and the maximum outer diameter of the protrusion 32 is slightly larger than the diameter of the fitting body 31. The expanded diameter portion 40 has a larger diameter than the protruding portion 32 of the insertion portion 30. Thereby, when the fitting part 30 of the post body 21 is fitted into the holding frame 10, it does not penetrate up to the enlarged diameter part 40. The enlarged diameter portion 40 comes into contact with the bottom surface of the stone seat portion 11 and acts as a stopper, making it easier to determine the pushing position when the pierced earring post 20 is inserted into the holding frame 10. Thereby, it is possible to prevent damage to the stone seat portion 11 due to forcible fitting of the pierced earring post 20 into the holding frame 10 and failure of attachment due to insufficient fitting.

As an example of the specific sizes of each part, the diameter of the post main body 21 is about 0.8 mm, the diameter of the insertion part main body 31 is about 0.8 mm, the diameter of the protruding part 32 is about 0.9 mm, and the diameter of the enlarged diameter part 40. is approximately 1.5 mm. These sizes are not limited to the above.

In this embodiment, since the post body 21 is formed of a high-hardness material that is harder than the holding frame 10, it is possible to attach the post body 21 to the holding frame 10 without deforming or damaging the post body 21. Yes, no brazing work is required. This makes it possible to easily attach the post body 21 to the holding frame 10 even if the worker does not have a skilled brazing technique.

Further, according to the present embodiment, the post body 21 is attached to the holding frame 10 by fitting the fitting portion 30 provided on one end side of the post body 21 into the holding frame 10, so that the post body 21 is formed. As the hard material, various materials (such as ceramics) that cannot be fixed by brazing or adhesives can be used. In particular, in this embodiment, it is possible to form the post body 21 using a material that does not easily cause allergies, such as ceramic, as a high-activity material, so that even users with allergic predispositions such as metal allergies can use the earrings 1. It becomes possible to do so.

Next, a method for attaching the earring post 20 will be explained.
FIG. 3 is an enlarged cross-sectional view (Part 1) illustrating a method of attaching a piercing post.
FIG. 4 is an enlarged cross-sectional view (part 2) illustrating a method of attaching the piercing post.
As shown in FIG. 3, the stone seat portion 11 of the holding frame 10 is provided with a pilot hole 10h. The diameter of the pilot hole 10h before the piercing post 20 is attached is made smaller than the diameter of the protrusion 32 of the insertion part 30. For example, when the diameter of the protrusion 32 is about 0.9 mm, the diameter of the lower hole 10h is about 0.5 mm to 0.6 mm.

The fitting portion 30 provided at one end of the post body 21 is pushed into the prepared hole 10h from the outside of the holding frame 10 (below the stone seat portion 11). As a result, the fitting part 30 is fitted into the holding frame 10 while the protruding part 32 pushes and expands the lower hole 10h.

Then, as shown in FIG. 4, the enlarged diameter portion 40 is pushed in to a position where it comes into contact with the back surface of the stone seat portion 11. When the enlarged diameter portion 40 comes into contact with the back surface of the stone seat portion 11, it functions as a stopper for the insertion of the post body 21, and further pushing is prevented. When the fitting part 30 is fitted into the pilot hole 10h, the edge of the pilot hole 10h is slightly raised in the insertion direction. After the protrusion 32 passes through the lower hole 10h, a part of this raised portion 10b is slightly returned by elastic deformation, and this portion 10b is caught on the protrusion 32. Therefore, the stone seat part 11 is inserted between the protruding part 32 and the enlarged diameter part 40, and the pierced earring post 20 is securely fixed to the holding frame 10 and will not come off.

With the earring post 20 connected to the holding frame 10, the jewelry 100 is placed on the stone seat part 11, and the jewelry 100 is fixed by bending the tip part 12a of the claw part 12. With this, the earring 1 is completed.

FIG. 5 is an enlarged cross-sectional view illustrating the recessed portion of the piercing post according to the present embodiment. FIG. 5A shows an end view of the protrusion 32, and FIG. 5B shows a schematic cross-sectional view of the insertion part 30 in which the recess 35 is provided.
FIG. 6 is a diagram illustrating the positional relationship between the recess and the jewelry. FIG. 6A shows a schematic cross-sectional view of the fitting part 30 provided with the recess 35, and FIG. 6B shows a schematic cross-sectional view illustrating the positional relationship between the recess 35 and the tip portion 101 of the jewelry 100.

It is preferable that a recess 35 into which the pointed end portion 101 of the jewelry 100 is fitted is provided on the distal end side of the fitting portion 30 . The recess 35 may be conical or hemispherical. In this embodiment, a hemispherical recess 35 is provided. As shown in FIG. 5A, the recess 35 is provided at the center of the distal end surface of the protrusion 32. As shown in FIG. The recess 35 is provided in a hemispherical shape. As shown in FIG. 5B, when viewed in cross section, the recess 35 is provided in a semicircular shape in the lower half. As an example, the diameter of the recess 35 when viewed from the tip side of the protrusion 32 is about 0.2 mm.

As shown in FIGS. 6A and 6B, when the jewelry 100 is placed in the holding frame 10 (see FIG. 1), the tip of the jewelry 100 is fitted into the recess 35. For example, when the jewelry 100 is a brilliant-cut gemstone, the angle θ (see FIG. 6B) of the culet portion, which is the tip portion 101, is approximately 98.5 degrees. On the other hand, when the recess 35 is hemispherical (semicircular in cross section), the angle formed by the line connecting the left and right edges P1, P2 of the recess 35 and the center P3 of the bottom of the recess 35 is It becomes 90 degrees.

Therefore, when the 98.5 degree pointed end portion 101 is fitted into the recess 35, before the leading edge 101p of the pointed end portion 101 comes into contact with the center P3 of the bottom of the recessed portion 35, the jewelry 100 is inserted into the edges P1, P2 of the recessed portion 35. It will come into contact with. This relationship is the same regardless of the diameter of the recess 35 as long as the recess 35 has a hemispherical shape (semicircular in cross section). Therefore, in the brilliant cut jewelry 100, the leading edge 101p of the culet comes into contact with the edges P1 and P2 of the recess 35 before hitting the bottom of the recess 35, without affecting the leading edge 101p of the culet. This means that 100 pieces of jewelry can be supported.

Further, by providing the recess 35, the mounting height of the jewelry 100 can be made lower than when the recess 35 is not provided. Thereby, the height of the holding frame 10 can be suppressed, and the material consumption of the holding frame 10 can be suppressed.

Next, another method of attaching the piercing post according to this embodiment will be explained.
7 to 9 are enlarged cross-sectional views illustrating other methods of attaching the piercing post.
First, as shown in FIG. 7A, a pilot hole 10h is formed in the holding frame 10, and the fitting portion 30 provided at one end of the post body 21 is pushed into the pilot hole 10h. As a result, the fitting part 30 is fitted into the holding frame 10 while the protruding part 32 pushes and expands the lower hole 10h.

Then, as shown in FIG. 7B, the enlarged diameter portion 40 is pushed into the position where it comes into contact with the back surface of the stone seat portion 11. When the enlarged diameter portion 40 comes into contact with the back surface of the stone seat portion 11, it functions as a stopper for the insertion of the post body 21, and further pushing is prevented. When the fitting part 30 is fitted into the pilot hole 10h, the edge of the pilot hole 10h is slightly raised in the insertion direction. This raised portion 10b is a portion where a portion of the edge of the lower hole 10h is turned up and deformed in the insertion direction by insertion of the insertion portion 30 (projection portion 32).

Next, as shown in FIG. 8, a presser 200 is applied from above the holding frame 10 toward the inside. The presser 200 has a protrusion 210 and a recess 220 provided inside the protrusion 210. The presser 200 is a bead-shaped tool made of a harder material than the holding frame 10. The recess 220 is slightly larger than the outer shape of the protrusion 32 of the insertion part 30.

Next, as shown in FIG. 9A, the presser 200 is placed over the protrusion 32 and pressed against the inside of the holding frame 10 from above. At this time, the recess 220 is placed over the protrusion 32, so that the protrusion 32 and the presser 200 do not interfere, and the protrusion 210 of the presser 200 is placed in the raised portion 10b around the protrusion 32. They come into contact with each other. By pressing the presser 200 in this state, the portion 10b is held between the enlarged diameter portion 40 and the convex portion 210 and crushed by the pressing force from the presser 200.

The crushed portion 10b is pushed into the lower side of the protrusion 32 (the constricted portion 31a provided closer to the rear end of the post body 21 than the protrusion 32). Thereafter, as shown in FIG. 9B, the presser 200 is removed. As a result, the portion 10b pushed into the constricted portion 31a becomes a hook to prevent it from coming off, and the fitted earring post 20 is firmly connected to the holding frame 10.

As explained above, according to the present embodiment, the pierced earring post 20 that does not require brazing work for attaching to the holding frame 10, the pierced earring 1 provided with such a pierced post 20, and the pierced earring on the holding frame 10 are provided. A method for attaching the post 20 can be provided.
