Description

The present invention relates to a clip-type earring.

The present inventor has conventionally proposed a novel clip-type earring.
First, in Japanese Patent Laid-Open No. 10-276810 (see Patent Document 1), as shown in FIG. 11, a main decorative body 21 having a pair of mounting legs 22, 23, and a pair of mounting legs 22, 23, a sandwiching member 24 having a mounting base 25 formed between the mounting legs 25, 23, and a washer 26 interposed between the mounting legs 22, 23 and the mounting base 25, and these pins are penetrated by pins 27, and We proposed an earring that gives pinching force when both parts are closed by caulking the part.

In the above-mentioned earring with a washer-like plate material interposed, it can be attached to the earlobe without demonstrating such a large clamping force due to friction between the two, and contact with each other by repeatedly opening and closing the two. Although it is possible to prevent the mounting leg and the mounting base from being worn or deformed by contact friction to some extent, the problem that the clamping force tends to decrease during use still remains.

Therefore, in the utility model registration No. 3130993 (Patent Document 2), the present inventor has a pair of mounting legs 32 and 33 on one main decorative body 31 and the other sandwiching member 34 as shown in FIG. The mounting base 35 is formed, and at least two or more smooth metal plate members 36 are interposed between the pair of mounting legs 32 and 33 and the mounting base 35, and these are pivotally attached by pins 37. The earring is formed by caulking the shaft portion together with the metal plate material 36, and an earring in which a recess 38 having a larger area than the metal plate material 36 is formed on the plate surface of the mounting base 35.

Further, it has been found that there may be one smooth metal plate material 36 between the pair of mounting legs 32, 33 and the mounting base 35, and Utility Model Registration No. 3139659 (Patent Document 3) is also disclosed. is suggesting.

JP-A-10-276810 Utility Model Registration No. 3130993 Utility Model Registration No. 3139659

As described above, in Utility Model Registration No. 3130993 (Patent Document 2) and Utility Model Registration No. 3139659 (Patent Document 3), one or two sheets are provided between the pair of mounting legs and the mounting base. The earring is formed by interposing a plurality of smooth metal plate members and attaching the shaft portion together with the metal plate material, and the plate surface of the mounting base is larger than the metal plate material. A recess having an area is formed.
However, although there is a merit that the clamping force can be maintained for a very long time by using one or more smooth metal plate materials, there is a problem that the manufacturing is complicated and the cost is increased.

The earring according to the present invention improves the above-mentioned drawbacks of the conventional earring, and includes a pair of smooth circular metal plates interposed between a pair of mounting legs and a mounting base. While using the thing of the area accommodated in the outline of an attachment leg part, the said attachment base is formed in the width thinner than the diameter of the said circular metal plate material, and one main decoration body and the other clamping member, When the mounting leg portion and the mounting base portion respectively formed on each other rotate relatively, the load applied to the circular metal plate material is applied to the intersecting portion with the edge in the width direction of the mounting base portion, thereby obtaining a large clamping force. Is intended to provide earrings that can withstand long-term use.

That is, the earring according to the present invention forms a pair of mounting legs and a mounting base on one main decorative body and the other sandwiching member, and one piece between the pair of mounting legs and the mounting base. An earring comprising two smooth circular metal plates having elasticity, which are axially attached, and the shaft portion is caulked together with the circular metal plate, wherein the mounting base is a diameter of the circular metal plate When the mounting leg and the mounting base formed on one main decorative body and the other sandwiching member rotate relative to each other, the circular metal plate is attached to the mounting plate. A portion of the mounting base that intersects the widthwise edge of the mounting base is bent inward by a load applied to a contact portion with the base, and the flexible portion engages with the edge of the mounting base . It is characterized by this.

In earring of the present invention, the diameter of the smooth circular metal plate material to have a range of slightly larger dimensions than the contour of the pair of mounting legs of the pair of mounting legs from dimensioned to be received in the contour of the It is also characterized by that.

In the earring of the present invention, the smooth circular metal plate is characterized in that its thickness is in the range of 0.1 to 0.25 mm.

The earring according to the present invention is characterized in that crossing lines in which the edge in the width direction of the mounting base crosses the outline of the circular metal plate material are arranged on both sides in the width direction of the mounting base.

As described above, in the present invention, a pair of mounting legs and a mounting base are formed on one main decorative body and the other clamping member, and one sheet is provided between the pair of mounting legs and the mounting base. Alternatively, two smooth circular metal plates having elasticity are interposed, and the mounting base is formed to have a width narrower than the diameter of the circular metal plate, and one main decorative body and the other sandwiching member are respectively provided. When the formed mounting leg portion and the mounting base portion rotate relatively, a load applied to the circular metal plate material is applied to a crossing portion with an end edge in the width direction of the mounting base portion.
By doing so, it is possible to achieve a remarkable effect that the clamping force is significantly improved and the clamping force is maintained for an extremely long period of time, and the clamping force that has been a weak point of this type of product. It has succeeded in fundamentally resolving the problems related to the sustainability.

Earring in this invention, the tab clamping force is increased dramatically as compared with the conventional to the ear, yet the function of the clamping force is to be held in the long-term constant, according to the circular metal plate elastic circular metal plate circular metal plate load acts on the intersection of the widthwise edge of the mounting base portion is due to the Tawamuko act delicately, be obtained such remarkable effects It is thought that it has become possible.
Further, also considered that the friction caused by the plate surface of the circular metal plate is engaged in contact with the linear at the intersection between the width direction of the end edge of the mounting base may be interfering with improvement of clamping force It is done.
By the way, in the conventional earring with a simple washer interposed, when the opening and closing operation was repeated several tens to hundreds of times, the clamping force was reduced. There was no decrease in the pinching force, and the pinching force itself was much better than the conventional washer-type earrings.

It is the schematic which shows another prior art example of an earring.

Hereinafter, embodiments of the earring of the present invention will be described in more detail with reference to the drawings.

In the embodiment shown in FIG. 1 to FIG. 6, 1 is a main decoration body, 2 is a sub-decoration body as an earlobe clamping part, and its overall shape is substantially the same arc shape, and in the assembled state it is a ring shape In this example, a jewel 13 made of diamond or the like is attached to the front side. Of course, both may be worn with either side facing the front of the earlobe. Moreover, the cross-sectional shape is a so-called Koumaru with a substantially arc shape. As materials, gold (K-18, etc.), platinum, silver, etc. can be used.
A pair of mounting leg portions 3 and 4 are integrally provided in the connecting portion of the main decorative body 1, and the fitting portion is fitted between the mounting leg portions 3 and 4 in the connecting portion of the sub-decorating body 2 so as to be opposed thereto. The base 5 is integrally formed.

Then, the pin 8 is inserted into the through holes 6 and 7 opened in these, and this portion is caulked, but at this time, the thickness 0 between the mounting legs 3 and 4 and the mounting base 5 is reduced. 0.1 to 0.25 mm, preferably 0.15 mm thick stainless steel or the like, which is crimped via one or two elastic circular metal plates 9 having elasticity .
The reason why the thickness of the smooth circular metal plate 9 is in the range of 0.1 to 0.25 mm is that the elasticity cannot be used when the thickness is 0.1 mm or less. Further, when the thickness is 0.25 mm or more, the elasticity of the circular metal plate 9 itself is lost.
The number of the circular metal plate material 9 may be one or two, but even if there are two, there is no problem in economical efficiency and workability of assembly, and the number of the circular metal plates 9 should be two in consideration of the persistence of the clamping force. Is desirable.
Reference numerals 10 and 11 denote ear pads formed on the end surfaces of the main decorative body 1 and the auxiliary decorative body 2.

In this embodiment, as shown in FIGS. 5 and 6, the area of the smooth circular metal plate 9 is formed so as to be accommodated within the outline of the pair of mounting legs 3 and 4. . On the other hand, the mounting base 5 is formed with a width narrower than the diameter of the circular metal plate 9.
And when the attachment leg parts 3 and 4 and the attachment base part 5 which were each formed in one main decoration body 1 and the other clamping member 2 rotate relatively, the load concerning the said circular metal plate material 9 is applied. The mounting base portion 5 is adapted to be applied to the intersection with the end edge 12 in the width direction.
In the example of FIG. 7, the diameter of the smooth circular metal plate 9 has a size range that is slightly larger than the outline of the pair of mounting legs 3 and 4. Further, in the example of FIG. 8, only the inner peripheral side of the ring-shaped earring has a size slightly larger than the outline of the pair of mounting legs 3, 4, and the outer peripheral side of the ring-shaped earring is the pair of mounting legs. The dimensions are almost the same as the contours of the portions 3 and 4.
In addition, it is desirable to arrange the crossing line where the edge 12 in the width direction of the mounting base 5 crosses the outline of the circular metal plate 9 on both sides of the mounting base 5 in the width direction.
Further, the edge 12 in the width direction of the mounting base 5 is formed in an arc shape having substantially the same curvature as the sub-decorative body 2 having an arc shape. Therefore, the intersecting line crossing the outline of the circular metal plate 9 is also rubbed in an arc shape, and the intersecting line formed in the arc shape also contributes to the persistence of the clamping force. It is done.

As shown in FIG. 9, the distal end portion of the mounting base 5 is formed in a so-called taper shape in the width direction of the mounting legs 3 and 4.
The load and according to the tapered portion of the distal end portion of the mounting base 5, the inner surface of the mounting leg portions 3 and 4, the intersection between the widthwise edges 12 of the mounting base 5 to the circular metal plate 9 It is considered that the pinching force is held constant for a long period of time due to the preferentially applied load.

In FIG. 10, the distal end portion of the mounting base 5 is formed in a so-called taper shape toward the inner back direction of the mounting legs 3 and 4.
Also in this example, as in the case of FIG. 9, the load applied to the tapered portion of the tip portion of the mounting base 5 and the width of the mounting base 5 on the circular metal plate 9 on the inner surfaces of the mounting legs 3 and 4. It is considered that the load applied mainly to the intersection with the edge 12 in the direction is combined, and the clamping force is kept constant for a long time.

Earring in this embodiment, clamping force to the tab ear increases dramatically as compared with the conventional, yet the function of the clamping force is to be held in the long-term constant, tightening the shaft portion when, circular metal plate 9 due to engagement at the intersection of the width direction of the end edge 12 of the mounting base 5 in a circular metal plate 9, Nde one or two circular metal plate 9 Gatawa It is considered that the elasticity of the film has been subtly acted to achieve such a remarkable effect.
Further, it is conceivable that friction between the edge 12 in the width direction forming the arc shape of the mounting base 5 and the plate surface of the circular metal plate 9 affects the improvement of the clamping force.

By the way, in the conventional earrings simply having a washer interposed, when the opening / closing operation was repeated several tens to hundreds of times, the clamping force was reduced, whereas in the earrings in this embodiment, the opening / closing operation was performed several hundreds of times. However, no decrease in the pinching force was observed, and the pinching force itself was far superior to the conventional washer-type earrings.

In the present invention, as described above, the mounting base is formed with a width narrower than the diameter of the circular metal plate, and the mounting leg and the mounting base formed on one main decorative body and the other sandwiching member, respectively. When the two are relatively rotated, a load applied to the circular metal plate material is applied to an intersecting portion with an end edge in the width direction of the attachment base portion.
Therefore, not only when using the arc-shaped pinching member as shown in the figure, it is also applicable to other designs, earrings using pinching members provided with pins for piercing, etc. Nor.
