Description

Technical Field

[0001] The invention relates to a clip-on structure for decorative items. Background Art

[0002] The inventor has previously proposed novel clip-on earrings.

[0003] First, in Japanese Patent Laid-Open No. 10-276810 (refer to Patent Document 1), a clip-on earring is proposed. Fig. 9 As shown, the clip-on earrings have a main decorative body 21 and a clamping component 24, wherein the main decorative body 21 has a pair of mounting legs 22, 23, and the clamping component 24 is formed with a mounting base 25 accommodated between the pair of mounting legs 22, 23, and a gasket 26 is clamped between the mounting legs 22, 23 and the mounting base 25. On this basis, a pin 27 is used to penetrate these components and the portion is tightened, so that a clamping force is applied when the main decorative body 21 and the clamping component 24 are closed.

[0004] Regarding the above-mentioned clip-on earrings with a gasket-like plate, they can be worn on the earlobe without exerting such a large clamping force by virtue of the friction between the main decorative body 21 and the clamping part 24, and can also to some extent prevent the mounting legs and mounting bases that are in contact with each other from being worn or deformed due to contact friction due to repeated opening and closing of the two. However, there is still the problem that the clamping force is easily reduced during use.

[0005] Therefore, the inventors proposed the following clip-on earrings in Japanese Utility Model Registration No. 3130993 (Patent Document 2): Fig.10 As shown, the clip-on earring has a pair of mounting legs 32, 33 formed on a main decorative body 31 on one side, and a mounting base 35 formed on a clamping component 34 on the other side, and at least two or more smooth metal plates 36 are clamped between the above-mentioned pair of mounting legs 32, 33 and the mounting base 35. The clip-on earring is formed by axially mounting these components using pins 37 and by chiseling the axially mounted portion and the above-mentioned metal plate 36 together, wherein a recess 38 having an area larger than that of the above-mentioned metal plate 36 is formed on the plate surface of the above-mentioned mounting base 35.

[0006] The present inventors have found that the smooth metal plate 36 provided between the pair of mounting legs 32 and 33 and the mounting base 35 may be a single piece, and have proposed Japanese Utility Model Registration No. 3139659 (Patent Document 3).

[0007] In the Japanese Utility Model Registration Gazette No. 3130993 (Patent Document 2) and the Japanese Utility Model Registration Gazette No. 3139659 (Patent Document 3), the earrings have one or more smooth metal plates sandwiched between the pair of mounting legs and the mounting base, the earrings are formed by axially mounting these parts and by fastening the axially mounted parts and the metal plates together, wherein a recessed portion having an area larger than that of the metal plates is formed on the plate surface of the mounting base.

[0008] However, although there is an advantage in that the clamping force can be maintained for an extremely long time by using one or more smooth metal plates, there is a problem in that the manufacturing is complicated and the cost increases.

[0009] Therefore, the inventor proposed the following clip-on earrings in Japanese Patent Gazette No. 4592116 (refer to Patent Document 4): the clip-on earrings have a pair of mounting legs formed on a main decorative body on one side, a mounting base formed on a clamping component on the other side, and one or more elastic and smooth metal plates are installed between the above-mentioned pair of mounting legs and the mounting base, the clip-on earrings are formed by axially mounting these components and then fastening the axially mounted parts and the above-mentioned metal plates together, wherein the above-mentioned mounting base is formed to have a width thinner than the diameter of the above-mentioned metal plate, and when the mounting legs of the main decorative body formed on one side and the mounting base of the clamping component formed on the other side rotate relative to each other, the intersection portion of the above-mentioned metal plate that intersects with the end edge in the width direction of the above-mentioned mounting base is bent inward due to the load applied to the abutting portion of the metal plate that abuts against the above-mentioned mounting base, and the bent portion is engaged with the above-mentioned end edge of the above-mentioned mounting base.

[0015] Patent Document 4: Japanese Patent No. 4592116 Summary of the invention

[0016] Problems to be solved by the invention

[0017] However, in the invention of Japanese Patent No. 4592116 (Patent Document 4), since the mounting base is formed to be narrower than the diameter of the metal plate, the metal plate may protrude from the mounting base to impair the appearance or may injure fingers during operation.

[0018] Therefore, the present inventors continued diligent research and found a mounting base having a cutout (convex type) during the process, and then tried to assemble a metal plate and verified its effect.

[0019] As a result, it was found that an effect of maintaining a clamping force equal to or greater than that of the invention of Japanese Patent No. 4592116 (Patent Document 4) for an extremely long period of time can be obtained.

[0020] Therefore, the clamping structure of the ornament of the present invention is intended to provide the following clamping structure of the ornament: the above-mentioned mounting base is formed with a groove or a cutout on its outer periphery, and when the mounting leg of the main decorative body formed on one side and the mounting base of the auxiliary decorative body (clamping component) formed on the other side rotate relative to each other, the above-mentioned metal sheet is bent inward toward the groove or the cutout of the above-mentioned mounting base, and the bent part is engaged with the end edge of the above-mentioned groove or the cutout of the above-mentioned mounting base. Therefore, the load applied to the above-mentioned metal sheet acts on the intersection part with the end edge of the groove or the cutout of the above-mentioned mounting base to obtain a larger clamping force, which can withstand long-term use.

[0021] Means for solving problems

[0022] That is, the clip-on structure of the ornament of the present invention is an earring composed of a main decorative body on one side and a sub-decorative body (clamp-on component) on the other side, a pair of mounting legs are formed at the end of the main decorative body, a mounting base clamped between the pair of mounting legs is formed at the end of the sub-decorative body (clamp-on component), and one or more elastic metal plates are clamped between the pair of mounting legs and the mounting base, the earring is formed by axially mounting these parts and fastening the axially mounted part and the metal plate together, and is characterized in that the mounting base is formed with a groove or cutout on its outer periphery, and when the mounting leg of the main decorative body formed on one side and the mounting base of the sub-decorative body (clamp-on component) formed on the other side rotate relative to each other, the metal plate is bent inward toward the groove or cutout of the mounting base, and the bent part engages with the end edge of the groove or cutout of the mounting base.

[0023] In the decorative article clip structure of the present invention, the thickness of the metal plate is in the range of 0.1 mm to 0.3 mm.

[0024] In the clip-on structure of the decorative article of the present invention, it is characterized in that the groove or cutout formed on the outer periphery of the attachment base has a U-shape or a V-shape in cross section.

[0025] Effects of the Invention

[0026] As described above, in the present invention, the mounting base is formed with a groove or a cutout on its outer periphery. When the mounting leg of the main decorative body formed on one side and the mounting base of the auxiliary decorative body (clamping component) formed on the other side rotate relative to each other, the metal sheet is bent inward toward the groove or the cutout of the mounting base, and the bent portion engages with the end edge of the groove or the cutout of the mounting base.

[0027] As a result, unexpectedly, a significant effect can be achieved in that the clamping force is higher than that of the invention of the above-mentioned Patent Document 4 and the clamping force can be maintained for an extremely long time, successfully solving the problem related to the duration of the clamping force, which is the weakness of this product, fundamentally.

[0028] In the experiment, when a prototype was used in which a U-shaped cross-section cut with a depth of 1 / 3 of its diameter was formed on the outer periphery of the mounting base and three metal plates with a thickness of 0.15 mm were arranged on both sides of the mounting base, the holding force was sufficient to withstand full use even after 5,000 opening and closing operations.

[0029] In the prior art of Patent Document 4, since the metal plate exceeds the width of the mounting base, the position of the shaft pin is deviated from the center position of the mounting base, and the mounting operation is very troublesome. However, this problem is solved in the present invention.

[0030] The clamping force of the ornament of the present invention on the earlobe is dramatically improved compared with the prior art, and the clamping force can be kept constant for a long time. As for this function, it can be imagined that the load applied to the metal plate acts on the intersection with the end edge of the groove or cutout of the mounting base, causing the metal plate to bend, thereby directly causing the elasticity of the metal plate to play a role, making it possible to achieve such a significant effect.

[0031] In addition, it is also conceivable that the friction generated by the contact and engagement between the plate surface of the metal plate and the intersection of the end edges of the groove or the notch of the mounting base may affect the improvement of the clamping force.

[0032] In addition, if the existing earrings with only gaskets are repeatedly opened and closed dozens to hundreds of times, the clamping force will be reduced. In contrast, even if the earrings of the present invention are opened and closed more than thousands of times, there is no reduction in the clamping force at all, and the clamping force itself is far superior to the existing gasket-type earrings.

[0043] Hereinafter, embodiments of the clip-on structure of a decorative article according to the present invention will be described in detail with reference to the accompanying drawings.

[0044] When the clip-on structure of the ornament of the present invention is applied to clip-on earrings Figures 1 to 6In the embodiment shown, 1 is the main decorative body, and 2 is the auxiliary decorative body as an earlobe clip-on component, and the overall shape thereof is roughly the same arc shape, and is ring-shaped in the assembled state. In addition, in this example, gemstones such as diamonds are not installed on the front surface side, but gemstones can be installed freely, and of course, both can be installed with either side facing the surface side of the earlobe. In addition, although the cross-sectional shape is also roughly a rectangular cross-section, a cross-section with an arc is not excluded. In addition, as raw materials, gold (K-18, etc.), platinum, silver, etc. can be used.

[0045] The main decorative body 1 has a pair of mounting legs 3 and 4 integrally formed at the connection portion thereof, and the sub-decoration body 2 has a mounting base 5 fitted between the mounting legs 3 and 4 integrally formed at the opposite connection portion thereof.

[0046] In addition, the axle pin 8 is inserted into the through holes 6 and 7 opened on the main decorative body 1 and the sub-decorative body 2, and the parts are tightened. At this time, one or more smooth metal plates 9 with elasticity and a thickness of 0.1mm to 0.3mm (preferably 0.15mm) made of stainless steel or the like are interposed between the mounting legs 3 and 4 and the mounting base 5 for tightening.

[0047] The reason why the thickness of the smooth metal plate 9 is in the range of 0.1 mm to 0.3 mm is that if it is less than 0.1 mm, the elasticity of the metal plate 9 cannot be exerted. If it is more than 0.3 mm, the elasticity of the metal plate 9 itself disappears.

[0048] The metal plate 9 may be one or two or more. Even when two or more are used, there is no problem in terms of economy and assembly workability. In consideration of the continuity of the clamping force, two or more are preferred.

[0049] In addition, reference numerals 10 and 11 are ear portions formed on the end surfaces of the main decorative body 1 and the sub-decorative body 2 .

[0050] In this embodiment, if Figure 3 (a), (b) to Figure 6 As shown, a groove or cutout 5a with a V-shaped cross-section is formed on the outer periphery of the above-mentioned mounting base 5. When the mounting legs 3, 4 of the main decorative body 1 formed on one side and the mounting base 5 of the auxiliary decorative body 2 formed on the other side rotate relative to each other, the above-mentioned metal plate 9 bends inward toward the groove or cutout 5a of the above-mentioned mounting base 5, and the bent portion engages with the end edge of the above-mentioned groove or cutout 5a of the above-mentioned mounting base 5.

[0051] That is, when the mounting legs 3 and 4 of the main decorative body 1 formed on one side and the mounting base 5 of the auxiliary decorative body 2 formed on the other side rotate relative to each other, the load applied to the above-mentioned metal sheet 9 acts on the intersection portion that intersects with the end edge of the above-mentioned groove or cutout 5a of the above-mentioned mounting base 5.

[0052] Figure 7 and Figure 8 Another embodiment of the present invention is shown, in which a groove or notch 5b with a U-shaped cross section is formed on the outer periphery of the mounting base 5. In addition, in the case of the groove or notch 5b with a U-shaped cross section, the same effect as the groove or notch 5a with a V-shaped cross section can be obtained.

[0053] The clamping force of the clip-on earrings of this embodiment on the earlobe is dramatically improved compared with the prior art, and the clamping force is kept constant for a long time. It can be imagined that this function is because when the axially mounted part is tightened, one or more pieces of metal plate 9 are bent and engaged at the intersection of the end edge of the groove or cutout 5a of the above-mentioned mounting base 5 that extends roughly radially from the axial pin 8, thereby causing the elasticity of the metal plate 9 to effectively play a role, making it possible to achieve such a significant effect.

[0054] In addition, it is also conceivable that the friction between the edge of the groove or the notch 5 a of the mounting base 5 and the plate surface of the metal plate 9 may affect the improvement of the clamping force.

[0055] In addition, if the existing earrings with only gaskets are repeatedly opened and closed dozens to hundreds of times, it will be found that the clamping force is reduced. In contrast, even if the earrings of this embodiment are opened and closed more than thousands of times, there is almost no reduction in the clamping force, and the clamping force itself is far superior to the existing gasket-type earrings.

[0056] Industrial Applicability

[0057] As described above, the present invention forms a groove or a cutout on the outer periphery of the above-mentioned mounting base. When the mounting leg of the main decorative body formed on one side and the mounting base of the auxiliary decorative body formed on the other side rotate relative to each other, the load applied to the above-mentioned metal sheet acts on the intersection portion that intersects with the end edge of the groove or the cutout of the above-mentioned mounting base.

[0058] Therefore, the present invention is applicable not only to the case of using an arc-shaped decorative body as shown in the figure, but also to earrings of other designs or provided with ear-piercing pins.

[0059] Furthermore, as long as the main purpose of the present invention is not changed, it can be applied not only to earrings but also to various decorative items that require opening and closing operations, such as rings and bracelets.
