  However, in the case of a small decorative body or a flat decorative body, it is difficult to make a hole with a sufficient depth, and it is difficult to securely fix the pin portion to the decorative body.

  In recent years, the pin portion or the like may be replaced with a metal pierced earring such as brass, and a titanium alloy or ceramic pin portion that is less likely to cause a metal allergic reaction may be used. However, since these materials are difficult to process materials, there is also a problem that it is difficult to engrave a screw at the tip of the pin portion. Furthermore, since titanium alloy and ceramics are difficult to press and weld, the attachment to the decorative body is limited.

  An object of the present invention is to provide a pierced earring that can solve the above-described problems and can securely fix a pin portion made of a material that is difficult to cause metal allergic reaction to a small decorative body or a flat decorative body. There is.

  The pierced earring according to the present invention for achieving the above object is provided with a decorative body and a head portion having an adhesive surface for the decorative body at the tip, and is a pin part that is difficult to process and is a material that is unlikely to cause a metal allergic reaction. And having a hole in the center, a cover or cone-shaped cover that can be inserted through the pin and covers the head, and a stopper that is inserted through the pin, and on the back surface of the decorative body In a state where the adhesive surface of the head is in contact, an adhesive is filled in a gap between the cover portion inserted into the hole portion and the back surface of the decorative body, and the pin portion is It is fixed to the decorative body.

  The pierced earring according to the present invention can be easily fixed to a decorative body even if it is a difficult-to-process pin part by fixing the pin part to the decorative body in a state where the cover portion is filled with an adhesive. it can. In particular, it is possible to firmly fix the pin portion for a decorative body having a flat portion.

It is a disassembled perspective view of the earring of an Example. It is sectional drawing of a piercing. It is explanatory drawing of the use state of a piercing.

The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is an exploded perspective view of a pierce 1 according to the embodiment, and FIG. 2 is a cross-sectional view showing a state in which a pin portion 3 is fixed to a decorative body 2. The pierced ear 1 includes a decorative body 2, a pin portion 3, a cover portion 4, and a stopper portion 5.

  Various materials and shapes made of jewels, resins, and metals can be used for the decorative body 2, but a flat surface is preferably formed on the back surface. In the embodiment, the decorative body 2 is, for example, a flat heart shape having a flat portion 2a on the back surface, and the material is made of resin, metal or the like.

  A pin portion 3 is bonded to the flat surface portion 2a, and a tip portion of the pin portion 3 is provided with a disk-shaped head portion 3a like a nail, for example. The surface of the head 3 a is a flat adhesive surface 3 b for increasing the contact area with the flat portion 2 a of the decorative body 2.

  The cover portion 4 has a bowl shape having an arcuate surface, and a hole 4a that can be inserted into the pin portion 3 is provided at the center. And the internal diameter of this hole 4a and the diameter of the pin part 3 are substantially corresponded. In addition, the cover part 4 can also employ | adopt cone shape other than a bowl shape.

  The cover portion 4 is inserted through the pin portion 3 and covers the head portion 3a from the outside in a state where the pin portion 3 is in contact with the decorative body 2. In addition, the volume of the recess inside the cover portion 4 is set to a size that can accommodate an amount of the adhesive B necessary to firmly fix the decorative body 2 and the pin portion 3.

  The stopper portion 5 can be inserted into the pin portion 3 and can be locked to the pin portion 3 in order to prevent the piercing 1 from falling off the earlobe. For example, the stopper portion 5 includes a spring. When the stopper portion 5 is pushed from the outside, the spring is loosened and can move along the pin portion 3. When the release portion is released, the spring returns and can be locked to the pin portion 3.

  Thus, the stopper portion 5 can be inserted into the pin portion 3 and can be locked at an arbitrary position of the pin portion 3 according to the thickness of the earlobe, for example.

  As the material of the pin part 3, the cover part 4, and the stopper part 5, it is preferable to use a material that is difficult to process but is molded from a titanium alloy or ceramics that is difficult to cause a metal allergic reaction. The cover portion 4 and the stopper portion 5 need not be stronger than the pin portion 3 and can be made of resin.

  At the time of assembly, the adhesive surface 3b of the head 3a of the pin portion 3 is brought into contact with the flat surface portion 2a of the decorative body 2, and the cover portion 4 is inserted into the pin portion 3 through the hole 4a. For example, an acrylic resin-based instantaneous adhesive B is accommodated inside the cover part 4 and the cover part 4 is pushed along the pin part 3 so as to cover the periphery of the head 3a.

  In this way, the adhesive B is filled in the gap between the cover portion 4 and the surface of the decorative body 2 in a state where the adhesive surface of the head 3 a is in contact with the decorative body 2. At this time, since the inside of the cover portion 4 is formed as a bowl-shaped depression, the adhesive B can be easily held, and also serves as a mold for the adhesive B during curing.

  In this way, the adhesive B is filled in the space between the decorative body 2 and the cover portion 4, and the periphery of the head 3 a at the tip of the pin portion 3 is fixed to the decorative body 2 by curing of the adhesive B. Is done. In addition, the adhesive B enters between the flat surface portion 2a of the decorative body 2 and the bonding surface 3b of the head portion 3a due to the surface tension, and bonding is also performed between the flat surface portion 2a and the bonding surface 3b.

  At the time of bonding, the amount of the adhesive B is often stored in the recess of the cover part 4, and it is preferable to wipe off the adhesive B that has been pushed out from the gap between the cover part 4 and the pin part 3, Even if the adhesive B is cured, no voids are generated in the interior, and the adhesion becomes stronger.

  In particular, the decorative body 2 also has a flat surface portion 2a and a bonding surface 3b of the head portion 3a, so that the head portion 3a can be sufficiently adhered to the decorative body 2, and the pin portion 3 is attached to the decorative body 2. On the other hand, it is fixed in a wide area, and the mounting strength can be greatly improved.

  When the adhesive B is cured, even if a force against the pin portion 3 is applied to the decorative body 2, the head 3a is fixed to the decorative body 2 including the periphery by the adhesive B. There is little possibility of peeling from the decorative body 2.

  Further, even after the adhesive B is cured, the cured adhesive B is covered with the cover portion 4 and does not come into contact with air or sunlight. Accordingly, the cured adhesive B is hardly deteriorated, and the adhesive effect of the adhesive B can be maintained for a long time.

  When using this earring 1, as shown in FIG. 3, the pin portion 3 is inserted into the hole formed in the earlobe E from the front surface of the earlobe E, the decorative body 2 is positioned on the front side of the earlobe E, and the earlobe E By inserting the stopper portion 5 into the pin portion 3 protruding to the rear side of the pin and locking it at an arbitrary position, the earlobe E is clamped with an appropriate force, and the earring 1 does not fall off from the earlobe E. .

  During use, the decorative body 2 comes into contact with the earlobe E through the cover portion 4, so that a gap is formed between the decorative body 2 and the earlobe E, and there is no inconvenience that the decorative body 2 directly touches the earlobe E. Also gets better.

  Thus, the piercing according to the present invention is a material that is difficult to cause metal allergic reaction by fixing the pin portion 3 to the decorative body 2 in a state where the adhesive B is filled in the cover portion 4. Even the pin part 3 which is a property can be easily fixed to the decorative body 2. In particular, for the decorative body 2 having the flat surface portion 2a, the pin portion 3 can be firmly fixed.
