However, in the above conventional example 1), the spring elasticity is utilized and the opening / closing operation is sharp and easy to use. On the other hand, the force is always applied in the direction in which the spring material is sandwiched. Had the disadvantage of becoming painful.

Further, in the conventional example 2), since the material of the earring itself is soft, the engaging portion is distorted and the movement is not smooth, the caulking force is too strong, and the earpiece is loose and immediately opens. It was either easy to fall off.

The conventional example 3) has become the mainstream in recent years. For example, the intervention of a stainless steel hard packing (washer) leads to smooth movement, and a method of fitting with a certain grip force. Is the same as the above method 2) and cannot be relieved. In addition, as in the case 2), if it is moved several times, the caulking portion becomes loose immediately and cannot be used reliably.

The ring-shaped earring of the present invention is intended to eliminate the above-mentioned drawbacks of the conventional example, and is intended to provide a ring-shaped earring that does not hurt even when used for a long time and does not easily come off the earlobe. .

That is, in the ring-shaped earring of the present invention, a pair of arc-shaped members are opposed to each other, and a connecting portion of one arc-shaped member is provided with a bearing portion, and a connecting portion of the other arc-shaped member is provided with a rotating portion and connected. coupled with the shaft, a ring-shaped earrings which enables opening and closing the other end of the arc-shaped member, by extending the pre-Symbol rotation unit to form an engaging portion provided with a protrusion at the tip, also of the rotating portion side along the periphery of the connecting shaft to form a tubular coupling guide, said bearing portion a recess for accommodating the engaging portion toward the inside, the inner back fixed length is at the portion of the front Symbol recess The U-shaped hard packing is interposed between the engaging portion and the recess, and the U-shaped hard packing has mounting holes corresponding to the connection guide and the protrusion. By providing the hard packing on both sides of the engaging portion The Rukoto the inner and outer walls of the engaging portions of the front Symbol recess is engaged through the rigid packing, to restrict the rotation of the pair of arcuate members, that it has prevented from falling out of the ear lobe earrings It is a feature.

Since the ring-shaped earring according to the present invention is configured as described above, there is almost no force in the direction in which the earlobe is sandwiched between the sandwiched body when worn, so that even if the ring-shaped earring is used for a long time, there is no pain.

In addition, the earlobe is not easily detached and can be easily attached to and detached from the earlobe.

Further, the structure is simple and the manufacturing is easy, and the adjustment of the force for pinching the earlobe and the retightening when loosened can be easily performed. Of course, it is possible to provide a ring-shaped earring that is easy to lower because of its simple structure.

Hereinafter, embodiments of the ring-shaped earring of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view showing an embodiment of a ring-shaped earring according to the present invention, FIG. 2 is a cross-sectional view of a main portion showing a state before a connecting portion is caulked, and FIG. 3 is a view showing a state after the caulking operation. FIG. 4 is a side view showing the assembled state, and FIG. 5 is a side view showing a state in which a pair of arcuate members are opened.

As shown in FIG. 1 to FIG. 3, in a pair of opposing arc-shaped members 1, 2, a bearing portion 3 is rotated at a connecting portion of one arc-shaped member 1, and a rotating portion is rotated at a connecting portion of the other arc-shaped member 2. A portion 4 is provided, and both are rotatably connected by a connecting shaft 5. The other ends of the arc-shaped members 1 and 2 can be opened and closed.

The rotating portion 4 is extended to form an engaging portion 6, while the bearing portion 3 is provided with a concave portion 7 for accommodating the engaging portion 6 inward. That is, the engaging portion 6 is housed in the concave portion 7 of the bearing portion 3, and the connecting shaft 5 is inserted into the shaft holes of both the bearing portion 3 and the rotating portion 4 and the both ends thereof are caulked to form a pair of circles. The arc-shaped members 1 and 2 are assembled.
In the figure, reference numeral 8 denotes a U-shaped hard packing interposed between the engaging portion 6 and the concave portion 7, and the inner wall of the concave portion 7 and the outer wall of the engaging portion 6 are engaged via the hard packing 8. By combining, the rotation of the pair of arcuate members 1 and 2 is restricted, and the earring is prevented from falling off the earlobe.

That is, the inner wall of the concave portion 7 and the outer wall of the engaging portion 6 are engaged via the hard packing 8, and the concave portion 7 is elastic when the rotation of the pair of arcuate members 1 and 2 is restricted. The engaging portion 6 is sandwiched by holding. Therefore, it is possible to reliably prevent the ear ornament from falling off the earlobe, and the movement of the rotating unit 4 when opening and closing between the closed position in FIG. 4 and the open position in FIG. 5 is extremely smooth. It will be something.
The engaging portion 6 is tapered toward the tip, and the concave portion 7 is engaged with the concave portion 7 at the wide portion to restrict the rotation of the pair of arcuate members 1 and 2. The elastic force for sandwiching the engaging portion 6 by 7 can be utilized to the maximum.

Since the cylindrical connection guide 10 is formed along the periphery of the connection shaft 5 on the side surface of the rotating portion 4 and the protrusion 11 is formed at the tip of the engaging portion 6, the U-shaped hard packing 8 is preliminarily formed in the above. By providing attachment holes corresponding to the connection guides 10 and the protrusions 11, the hard packing 8 can be attached to both sides of the engaging portion 6 with one touch only by fitting the connection guides 10 and the protrusions 11 into the attachment holes. And is securely held so that it does not come off during use.

As shown in the figure, a slit 9 having a predetermined length is further formed in the recess 7 at the inner back. By doing so, the elastic force acting on the bearing portion 3 due to the presence of the concave portion 7 for accommodating the rotating portion 4 can be increased by the action of the slit 9. Therefore, since the concave portion 7 of the bearing portion 3 has an elastic force to increase the operational effect when the engaging portion 6 is sandwiched, the fall of the earring from the earlobe can be reliably prevented, and the rotating portion 4 The movement will be very smooth.

The cylindrical connection guide 10 formed along the periphery of the connection shaft 5 in the rotating portion 4 is fitted into the concave groove 12 provided inside the bearing portion 3 to assemble both the connection guide 10 and the concave groove 12. As a result, the pair of arc-shaped members 1 and 2 are connected at the engaging portion between the connecting guide 10 and the recessed groove 12, and the load on the connecting shaft 5 is greatly reduced, so that it can be used for a long time. There is no problem.

Furthermore, in the caulking portion of the connecting shaft 5, the concave portions 13 are provided on both outer surfaces of the bearing portion 3, and the caulking portions at both ends of the connecting shaft 5 are stored in the concave portion 13, so that the caulking portion is It is shaped like a nail head and can be securely prevented from coming off, and the engagement pressure between the bearing portion 3 and the rotating portion 4 can be maintained for a long time. Of course, it is also possible to improve the smoothness without any problem by grinding the caulked portion so as to be the same plane as the outer surface of the bearing portion 3.
The caulking of the connecting shaft 5 in this case is not forcibly tightening, but is caulking for maintaining a constant gap between the bearing portion 3 and the rotating portion 4 in the connecting shaft 5 portion as shown in FIGS. Therefore, the hard packing 8 is not necessarily required, and the presence or absence of the hard packing 8 can be properly used depending on the product.

In the figure, 14 is a protrusion provided at one open end of the pair of arcuate members 1 and 2, and 15 is a recess provided corresponding thereto. By sandwiching an earlobe between them, the ring of the present invention is provided. It functions to more reliably prevent the ring earrings from falling off the earlobe.

Since the earring of the present invention is configured as described above, if it is a ring-shaped earring, a pierced pin may protrude from one open end of the pair of arcuate members 1 and 2, It does not have to be protruding.
