Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pierce which comprises a main body pin having a decorative portion at one end and a peripheral groove at the other end, and a stopper detachably attached to the peripheral groove.

[0002]

2. Description of the Related Art In FIG. 4, a pierce 10 is composed of a main body pin 11 extending in an axis Z direction and a stopper 41. A decorative portion 21 for attaching the decoration 70 is provided at one end of the body pin 11, and a peripheral groove 31 is provided at the other end. Therefore, the body pin 1
1 is inserted into the hole 101 formed in the earlobe 100, and the pin insertion portion 42 of the stopper 41 is pushed from the other end to be fitted into the main body pin 11, and the spring portion 43 is fitted into the circumferential groove 31. To meet. That is, the earring 10 (11, 41)
Can be attached to 00.

The decoration 70 such as jewelry is attached to the mounting ring 60 (hole 61) fixed to the decorative portion 21 through the engaging portion 71. Some of the decorations 70 (71) can be attached to and detached from the mounting ring 60 (61). However, the mounting ring 60 (6
1) As for itself, a part 62 thereof is fixed to the lower surface of the decorative portion 21 by a processing method such as brazing, adhesion, welding, etc., and is not detachable from the decorative portion 21. In other words, in order to prevent the expensive decoration 70 from being dropped, the decoration 70 is firmly fixed integrally.

Here, the main body pin 11 including the decorative portion 21
Is manufactured by a processing method selected from casting, forging, rolling, turning, etc., in consideration of its material and cost. When the material is gold or silver, it is left as it is, and when it is copper alloy, stainless steel, or the like, it is plated with gold, palladium, nickel, chromium, or the like.

[0005]

By the way, the piercing 10
Everyone agrees that the structure and mounting method of the above can surely prevent the falling loss of the decoration as compared with the spring type or screw type earrings. However, it is also known that there is a risk of so-called metal allergy, because the method of mounting is the method of inserting the body into the human body (ear lobe 100). That is, there are always conflicting problems of enjoying decorative beauty and preventing metal allergies. Therefore, if this problem can be solved, it can be promised to further spread.

Conventionally, however, when public health has the first meaning, ceramics, titanium, etc. are selected and used as a material which is unlikely to cause metal allergy. However, since these inert materials have extremely poor workability and are difficult to manufacture, they are inevitably manufactured by turning.
Therefore, the pierce 10 (11, 21, 41) has a uniform shape as shown in FIG. Also, it is often difficult to allow the mounting ring 60 as shown in FIG. 4 to be fixed to the pierce 10 (21) made of such an inert material in a separate process such as bonding after the completion of cutting in terms of cost. . In addition, it is difficult to fix it by brazing.

On the other hand, from the decorative portion 21 to the mounting ring 60 (7
Since it is not possible to eliminate the fear that (0) will peel off, the target person who can purchase even at a high cost is afraid to drop the expensive decoration 70 attached via the mounting ring 60, and refrain from purchasing it. To do. Thus, the decoration of the pierce 10 made of an inert material capable of preventing metal allergy is limited to the small particles (80) that can be embedded and mounted in the mounting hole 22 formed in the decorative portion 21.

However, there is a strong desire for decorative beauty, and there is a strong desire to wear various decorations 70 and 80 without fear of metal allergy. Further, there is no limit to the demand, and it is a reality that there is a demand to wear the decorations 70 and 80 that are not in the form of hanging from the decoration portion 21 and that the pierce 10 cannot be seen from the outside. Furthermore, the interchangeability of the decorations 70 and 80 is also required.

An object of the present invention is to provide a pierced earring which does not cause metal allergy, can be easily fitted with various kinds of decorations, and is easy to handle.

[0010]

[Means for Solving the Problems] A material that does not cause metal allergies must be manufactured by turning and the decorative portion 21 is integrally formed with the main body pin 11. If the material does not come into direct contact with the human body (ear lobe 100), the metal is used. Focusing on specific technical matters such as allergy cannot occur, the present invention limits the material to titanium, titanium alloy or ceramic which is inactive to the human body, while eliminating the concern about metal allergy, and the main body pin 1
1. A mounting groove 25 that can be machined in series during turning of the decorative portion 21 and the decorative portion 21 is provided on the outer peripheral surface of the decorative portion 21, and the mounting groove 25 can be used to directly or indirectly attach or detach the decoration. is there.

That is, the present invention is a pierce comprising a main body pin having a decorative portion at one end and a peripheral groove at the other end, and a fastener detachably formed in the peripheral groove, the decorative portion including the decorative portion. The main body pin is made of titanium, a titanium alloy, or ceramics, and a mounting groove centered on the axis is integrally formed on the outer peripheral surface of the decorative portion.

[0012]

According to the present invention having such a structure, the mounting groove can be formed in series when the main body pin and the decorative portion are processed by turning, for example, a round bar made of titanium, titanium alloy or ceramic. Therefore, as compared with the conventional example in which the mounting ring is fixed to the decorative portion by a separate process, for example, by adhesion after finishing the machining, the mounting groove in which the decoration can be mounted can be formed at low cost. When using it, the main body pin and the decorative part are made of an inert material, which eliminates the worry of metal allergies. Moreover, by using the mounting groove, various kinds of decorations whose size and shape are not restricted can be easily attached.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the pierced earring 10 has a body pin 11 including a decorative portion 21 made of titanium, a titanium alloy, or a ceramic, and has an axis Z on the outer peripheral surface of the decorative portion 21.
The mounting groove 25 centering on the above is integrally configured so that conflicting matters of enjoying the beauty of decoration and preventing metal allergy can be solved at once. That is, while eliminating the worry of metal allergies, various types of decoration 70, 80
Is formed so that it can be mounted.

In FIG. 1, the body pin 11 including the decorative portion 21 is a round bar material of 6Al4V (6 aluminum, 4 vanadium) titanium alloy, which is the most inactive to the human body among the existing materials in this embodiment. It is processed and formed by turning. The circumferential groove 31 is also formed simultaneously. Further, the decoration portion 21 is provided with a mounting hole 22 so that the same decoration 80 as in the conventional example (FIG. 5) can be enjoyed.

Here, the mounting groove 25 is formed while the decorative portion 21 is being turned. Therefore, it is continuously provided on the outer peripheral surface of the decorative portion 21 around the axis Z. This mounting groove 25
Has a width w of 0.5 mm and a depth d of 0.3 mm. Also, the mounting groove itself is provided with two mounting grooves 25, 26 so as to induce a certain aesthetic feeling. Of course, this mounting groove 26, instead of the mounting groove 25,
Or the decoration 70 together with the mounting groove 25
It can be used for mounting.

The stopper 41 (pin insertion portion 42, spring portion 43) is also made of the same material as the main body pin 11 provided with the circumferential groove 31. Regarding the function, the conventional example (Figs. 4 and 5)
The description is omitted because it is the same as the case.

Here, in order to mount the decoration 70 using the mounting groove 25 (26), it is desirable to indirectly mount by using the locking member 50 as shown in FIG. Since these locking members 50 do not come into direct contact with the human body (ear lobe 100, face and neck muscles), they can be manufactured from various materials that can be easily processed (for example, copper alloy).
Therefore, it is understood that the locking member 50 can be manufactured at a very low cost as compared with the case where the mounting ring 60 of the conventional example (FIG. 4) is fixed to the decorative portion 21 by adhesion or the like.

The locking member 50 shown in FIG. 2A is a snap type in which a plurality of locking projections 53 are provided inside a snap ring 52 which can be expanded and contracted by elastic deformation. Therefore, when the opening is pushed into the decorative portion 21, that is, the mounting groove 25 (26) from the radial direction, each locking projection 53 is attached to the mounting groove 25.
(26) is fitted and locked. Also, snap ring 52
By using the mounting hole 51 provided under the, various kinds of decorations 70 can be surely attached.
That is, if the decoration 70 is attached to the attachment hole 51 in advance, the attachment can be easily attached only by engaging the locking member 50 with the mounting grooves 25 and 26.

The locking member 50 shown in FIG. 2 (B) is of a wire spring type, and one end thereof is a ring (mounting hole 51).
Further, the locking member 50 shown in FIG. 2C is composed of a movable locking piece 55 and a fixed locking piece 54 which can be opened and closed centering around the pin 56.

Further, as shown in FIG. 3, if the locking member 50 has a spring portion 59 similar to that of the stopper 41 (43) and is formed so as to be fitted to the decorative portion 21, Even the large decoration 80 can be attached so as to cover the pierce 10 (21) itself on the axis Z, instead of the conventional uniform hanging manner.

[0021]

According to the present invention, the main body pin including the decorative portion is made of titanium, titanium alloy or ceramic, and the mounting groove centering on the axis is integrally formed on the outer peripheral surface of the decorative portion. Therefore, the following excellent effects can be achieved.

Since it is formed of titanium, titanium alloy or ceramic, it is possible to eliminate the worry of metal allergy. Since the decoration groove is formed in the decoration part, various kinds of decorations can be surely installed without fear of falling, so the decorative beauty can be significantly expanded by adopting large, expensive, specially designed jewelry. . Since the mounting groove can be processed simultaneously during turning of the decorative part, the processing cost can be significantly reduced compared to the conventional example in which the mounting ring is fixed to the processed decorative part by adhesion or the like. It can eliminate the conventional peeling and falling problem of the ring. If the mounting groove is used, it is possible to mount even a large-sized decoration that covers the decorative portion. If the decoration is indirectly attached to the decorative portion by using the detachable locking member in the mounting groove, various decorations can be enjoyed by a simple operation. By simply providing the mounting groove in the decorative portion, the main body pin including the decorative portion, the peripheral groove, and the fastener are the same as in the conventional structure, so that various kinds of decorations can be attached and detached while maintaining easy handling.
