Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip earring.

[0002]

2. Description of the Related Art As a conventional earring, there is known a clip-type earring in which the elasticity of a leaf spring or a coil spring is used to pinch an earlobe. There is a drawback that the earlobe becomes painful when worn.

As a device for adjusting the pinching force to the earlobe, there is a device for adjusting the pinching force of a decorative body for pinching the earlobe according to the degree of frictional resistance of the rotating shaft. This is to tighten the pair of mounting legs from one decorative body and the part to be clamped from the other decorative body side to shaft, and to increase the contact friction resistance between the two when the earlobe is pinched. To do
The feature is that it does not need to give a large pinching force to the earlobe. However, this method also has a major drawback. If the opening and closing are repeated for a long period of time, the crimped mounting leg and the other clamped part will be worn out, making it useless at all.

[0004]

The present applicant has proposed a new earring in Japanese Patent Application No. 9-108119 in order to solve such a problem, and has been widely adopted. The present invention is directed to a further improvement of such a proposal, in which the performance as an earring and the workability in a manufacturing process are improved.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the present invention is to provide an abutting portion at one end of one decorative body and a pair of mounting legs at the other end. The other decorative body is formed with an abutment on one end of the other decorative body and a clamped portion sandwiched between the mounting legs at the other end, and the mounting leg and the clamped portion are rotated by a shaft. An earring that is pivotally attached to a shaft member, wherein a sliding member that is harder than the mounting leg portion and the clamped portion is fixed to at least one of the sides around the shaft member. is there.

[0006]

FIG. 6 is an exploded view of a conventional earring. Reference numeral 21 denotes a main decorative body, and reference numeral 22 denotes a sub decorative body. These are made of K-18 as a whole, and the main decorative body 21 is provided with a pair of mounting legs 23 and 24, and the auxiliary decorative body 22 side has the mounting legs 23 and 2.
4 are formed, and these are pin 26
Penetrates and crimps this portion to provide a pinching force when both are closed. Reference numerals 27 and 28 are pin holes. Such earrings can be attached to the earlobe without exerting a large pinching force due to friction between the earlobes. Part 25
Are worn or deformed by contact friction, so that the pinching force is lost after a short use.

FIG. 7 shows a proposal already proposed by the present applicant (Japanese Patent Application No. 9-1).
FIG. 08119 is an exploded view of the earring. In the figure,
Reference numerals 21 to 28 have the same contents as described above, and are omitted here. Now, in this proposal, between the mounting legs 23 and 24 and the clamped portion 25, a thickness of 0.1 mm, which is higher in hardness than both members.
It is caulked with a stainless steel washer 30 of 15 mm in between. Accordingly, when the opening and closing of the main decoration body 21 and the sub-decoration body 22 of the earring are performed, relatively soft members do not directly contact each other, that is, the mounting legs 23 and 24 and the clamped portion 25, These are no longer worn out early. However, since the washer 30 rotates around the pin 26, depending on how the washer 30 is used, the washer 30 may rotate eccentrically, and the initial durability may not be maintained. Further, since the washer 30 is extremely small, it requires careful attention when assembling the earring, and is not good in workability.

EXAMPLES The earrings of the present invention will be further described below with reference to examples. The earring of the present invention improves the above-mentioned drawbacks of the earrings. FIG. 1 is a perspective view of the earring of the present invention, FIG. 2 is a development view seen from the inside of the earring, and FIG. FIG. 4 is an enlarged cross-sectional view taken along the line AA in FIG. In the figure, reference numeral 1 denotes a main decorative body, 2 denotes a sub decorative body, and their overall shapes are substantially the same. In this example, both sides may be mounted with their sides facing the front side of the earlobe. It is shaped.
Both are made of K-18.

The main decorative body 1 is provided with a pair of mounting legs 3 and 4, and the sub-decorative body 2 is provided with a clamped portion 5 fitted between the mounting legs 3 and 4 in opposition thereto. Have been. Then, the pin 8 is inserted into the through holes 6 and 7 formed in these, and this portion is crimped. In this example, the pinched portion 5 surrounds the through hole 7 and is harder than each member (K-18). And a stainless steel sliding member 9 having a high thickness of 0.15 mm. Therefore, when the earring is axially attached to the main decorative body 1 and the auxiliary decorative body 2, a sliding member 9 having a higher hardness than these materials is fixed to at least one surface and axially mounted, and this portion is added. It is a tightened one. Note that reference numeral 1
Reference numeral 0 denotes an earlobe contact portion of the main decorative body 1 and the sub decorative body 2.

As described above, according to the present invention, when the main decoration 1 and the sub-decoration 2 are attached to each other, a hard sliding member is fixed to the attachment portion, and contact between soft objects is prevented. Surprisingly, wear and deformation were avoided by avoiding,
The earrings can be used for a long period of time. The means for fixing the sliding member 9 is not particularly limited, but is usually fixed by brazing or an adhesive.

In the earring of the present invention, an example is shown in which the attachment legs 3 and 4 are provided on the side of the main decorative body, and the clamped portion 5 is provided on the side of the sub-decorative body. Of course, a sliding member 9 may be provided on the mounting leg portions 3 and 4 side.
Needless to say, it is also possible to fix the
Also, the sliding members 9 may be fixed to both sides of the mounting leg portions 3 and 4 and the clamped portion 5.

As a modification of the present invention, as shown in FIG. 5, an annular concave portion 11 is formed on the surface of the to-be-clamped portion 5, and the sliding member 9 is fitted and fixed in the concave portion 11. Is also conceivable.

Here, a repetitive opening / closing test of the earring of the present invention shown in FIG. 1 and the conventional earring shown in FIG. 6 was performed. The test consisted of the main decoration 1 and the sub decoration 2 of the earring.
Was opened and closed at 180 degrees, and the number of repetitions was indicated by an index. As a result of the evaluation, when the number of repetitions of opening and closing (index) of the conventional earring is set to 100, in the case of FIG.
Is severely worn and has almost no pinching force on the earlobe. However, each of the earrings of the present invention is 200
Even if it was (index) or more, the pinching force on the earlobe was sufficiently maintained, and the mounting legs 3, 4 and the base pinching portion were hardly worn. Also, since the sliding member is fixed also during the assembly as the earring, it is not necessary to handle extremely small parts, and the assembling work is relatively easy. On the other hand, in the case of the earring in FIG.
The improvement in this respect was sufficient, but the washer was not fixed during the assembly as the earring, so that the assembling work took a lot of trouble.

[0014]

According to the present invention, a sliding member having a higher hardness than the mounting leg portion and the clamped portion of the earring is secured around the shaft, so that the clamping force on the earlobe is constant for a long time. , And the assembly work as earrings was relatively simple.
