Description

Technical Field

[0001] The present invention relates to an ornament that is capable of dangling.Background Art

[0002] Pendants (necklaces) and the like in which a gemstone such as a diamond is held with use of a mount portion, and in which the gemstone and the mount portion are arranged to minutely dangle have been known.

[0003] When the gemstone held with use of the mount portion minutely dangles, the gemstone looks more sparkling than in a stationary state. Thus, beauty of the gemstone is further emphasized.

[0004] For example, a double-ring mechanism in which two coupling portions each including two jump rings engaged with each other are provided on both sides so that a decorative element can dangle with use of a total of the four jump rings.

[0005] In such a double-ring mechanism that is employed in the pendant and the like in the related art, since the coupling portions are present respectively on the right and the left, the decorative member dangles about a single imaginary-rotation axis.Citation ListPatent Literature

[0006] Patent Literature 2 provides an accessory capable of improving the swinging sensitivity. In a use mode having such a relationship that a second decoration part component is positioned on the lower side of a first decoration component, the cross-sectional shape of the inner circumferential part of a connecting fitting and the inner circumferential part of a fitting to be connected which contact with each other is formed into an angular shape having linear ridges and respectively. When the cross sectional shape of the inner circumferential part of the connecting fitting and the inner circumferential part of the fitting is formed into the angular shape having the linear ridges respectively, such constitution can provide a substantially line contact state by the linear ridge lines. Consequently, a contact resistance of the contact part between the inner circumferential part of the connecting fitting and the inner circumferential part of the fitting is reduced and the second accessory component having a reflector swing more finely and subtly than the conventional one so as to improve the swinging sensitivity.

[FIG. 7] FIG. 7 is an explanatory view illustrating a distance between a post and point-link portions in the pierced earring according to the embodiment. [FIG. 8] FIG. 8 is an explanatory view of a necklace which does not form an embodiment of the present invention.

[0014] Below, a pierced earring according to an embodiment of an ornament of the present invention is described with reference to the drawings.

[0015] FIG. 1 is an overall exterior view of a pierced earring 1 according to the embodiment of the present invention.

[0016] FIG. 2 is an enlarged cross-sectional view of a part including a first jump ring 21, a second jump ring 23, and a decorative element 31 of the pierced earring 1 illustrated in FIG. 1.

[0017] As illustrated in FIG. 1, the pierced earring 1 includes a post 11 and a fixing portion 13. The fixing portion 13 is provided at one end of the post 11, and is fixed (fitted) to an earlobe.

[0018] One end of a distance adjustment member 17 is provided at another end of the post 11.

[0019] The first jump ring 21 is provided (fixed) to another end of the distance adjustment member 17.

[0020] A second jump ring 23 is engaged with the first jump ring 21 in a manner that allows the second jump ring 23 to dangle.

[0021] A cross-section of a distal end of the first jump ring 21 and a cross-section of a distal end of the second jump ring 23 are each formed in a tapered shape that protrudes at a distal angle of 60° to 90° to an inner side (center of circumference).

[0022] With this, an inner periphery of the first jump ring 21 and an inner periphery of the second jump ring 23 are linked in point contact to each other, which allows the second jump ring 23 to dangle about three axes that are orthogonal or substantially orthogonal to each other relative to point-link portions 41 of the point contact.

[0023] The decorative element 31 is fixed to the second jump ring 23. The decorative element 31 is an object that performs a decorative function, such as a gemstone.

[0024] FIG. 3 is an explanatory view illustrating how the second jump ring 23 of the pierced earring 1 according to the embodiment of the present invention dangles about a Z-axis.

[0025] FIG. 4 is an explanatory view illustrating how the second jump ring 23 of the pierced earring 1 according to the embodiment of the present invention dangles about an X-axis.

[0026] FIG. 5 is an explanatory view illustrating how the second jump ring 23 of the pierced earring 1 according to the embodiment of the present invention dangles about a Y-axis.

[0027] The first jump ring 21 and the second jump ring 23 are point-linked to each other at the point-link portions 41 at the distal ends of the inner peripheries of both the rings. Thus, as illustrated in FIG. 3 to FIG. 5, in conjunction with motions of a user with the fixing portion 13 of the pierced earring 1 fitted to his / her earlobe, the second jump ring 23 dangles about the Z-axis, the X-axis, and the Y-axis (three axes) that are orthogonal or substantially orthogonal to each other about the point-link portions 41 of the point contact. When the second jump ring 23 dangles simultaneously about the Z-axis, the X-axis, and the Y-axis (three axes), the second jump ring 23 can dangle in more diverse and unpredictable ways than those in a case where the second jump ring 23 dangles about one axis. With this, an aesthetic appearance to be exhibited by the dangling is more emphasized than that of the pendant having the double-ring mechanism described in "Background Art."

[0028] FIG. 6 is an explanatory view illustrating a distal angle α in the cross-sections of the first jump ring 21 and the second jump ring 23.

[0029] In this embodiment, an inner diameter of the first jump ring 21 and an inner diameter of the second jump ring 23 are each 0.80 mm to 1.50 mm.

[0030] Further, an outer diameter of the first jump ring 21 and an outer diameter of the second jump ring 23 are each 1.40 mm to 2.00 mm.

[0031] Still further, a width of the first jump ring 21 and a width of the second jump ring 23 are each 0.20 mm to 0.50 mm.

[0032] In such shapes of the first jump ring 21 and the second jump ring 23, the distal angle α in the cross-sections of the first jump ring 21 and the second jump ring 23 is set to 60° to 90°. With this, even when the second jump ring 23 dangles with the pierced earring 1 put on an ear, the second jump ring 23 does not hit against the inner periphery of the first jump ring 21 out of the point-link portions 41. As a result, the second jump ring 23 dangles over a long period of time.

[0033] FIG. 7 is an explanatory view illustrating a distance between the post 11 and the point-link portions 41 in the pierced earring 1 according to this embodiment.

[0034] In the above-described sizes of the first jump ring 21 and the second jump ring 23, a distance between a position at which the earlobe is subjected to the fixation with use of the fixing portion 13 and the point-link portions 41 is set to 4 mm or more. With this, the second jump ring 23 can avoid hitting against the ear while dangling.

[0035] As described above, in the pierced earring 1, the cross-section of the first jump ring 21 and the cross-section of the second jump ring 23 are each formed in the tapered shape that protrudes at the distal angle of 60° to 90° to the inner side (center of circumference). With this, the inner periphery of the first jump ring 21 and the inner periphery of the second jump ring 23 are linked to each other at a point, that is, at the point-link portions 41. Thus, the second jump ring 23 and the decorative element 31 dangle about the Z-axis, the X-axis, and the Y-axis (three axes) relative to the point-link portions 41. This allows a dangling pattern to be more diversified than that of the pendant having the double-ring mechanism described in "Background Art."

[0036] Further, in the pierced earring 1, a simple dangling mechanism of can be obtained by engaging the first jump ring 21 and the second jump ring 23 with each other.

[0037] Still further, in the pierced earring 1, as described above, the first jump ring 21 and the second jump ring 23 are sized such that the second jump ring 23 can dangle over a long period of time without hitting against the inner periphery of the first jump ring 21 out of the point-link portions 41.

[0038] The link portions of a first curved portion of the first jump ring 21 and a second curved portion of the second jump ring 23 each have the substantially fan-like tapered shape that protrudes at the distal angle of 60° to 90° to the inner side in cross-section. With this, even when the first jump ring 21 and the second jump ring 23 relatively widely dangle, their inner peripheral portions do not come into contact with each other. This allows the first jump ring 21 and the second jump ring 23 to dangle over a long period of time.

[0039] In other words, if the distal angle of any one of the inner peripheral portions is more than 90°, the inner peripheral portions are liable to come into contact with each other by the dangling.

[0040] In addition, the first jump ring 21 and the second jump ring 23 come below the earlobe of the user. With this, the first jump ring and the second jump ring can avoid being suppressed from dangling by coming into contact with the earlobe.

[0041] Yet further, in the pierced earring 1, the distance between the position at which the earlobe is subjected to the fixation with use of the fixing portion 13 and the point-link portions 41 is set to 4 mm or more. With this, the second jump ring 23 can avoid hitting against the ear while dangling.

[0042] Note that, the present invention is not limited to the examples described above in the embodiment of the present invention or to its application examples but is defined by the claims.

[0043] For example, the ornament of the present invention need not necessarily be the pierced earring, and may be a non-pierced earring.

[0044] Further, the distal angle of each of the first jump ring 21 and the second jump ring 23 is not limited in particular as long as this distal angle falls within the range of 60° to 90°.

[0045] Yet further, the distal angle of the inner periphery of the second jump ring 23 may be set to be lower than the distal angle of the inner periphery of the first jump ring 21. Such a setting allows the second jump ring 23 to further widely dangle while strength of the first jump ring 21 is maintained.

[0046] Yet further, the inner diameter of the second jump ring 23 may be set to be smaller than the inner diameter of the first jump ring 21. Such a setting allows the decorative element 31 to be further eye-catching while a dangling function is maintained.

[0047] The present invention need not necessarily be applied to a non-pierced earring as in the exemplary case of the above-described embodiment of the present invention.

[0048] FIG. 8 is an explanatory view of a necklace which does not form an embodiment of the present invention.

[0049] As illustrated in FIG. 8, a necklace 101 includes a string-like member 105 to which the first jump ring 21 described with reference to FIG. 2 is fixed. The second jump ring 23 is engaged with the first jump ring 21 with the first jump ring 21 in the manner that allows the second jump ring 23 to dangle.

[0050] The cross-section of the distal end of the first jump ring 21 and the cross-section of the distal end of the second jump ring 23 are each formed in the fan-like tapered shape that protrudes at the distal angle of 60° to 90° to the inner side (center of circumference) in cross-section.

[0051] With this, the inner periphery of the first jump ring 21 and the inner periphery of the second jump ring 23 are linked in point contact to each other. This allows the second jump ring 23 to dangle about the three axes that are orthogonal or substantially orthogonal to each other relative to the point-link portions 41 in the point contact.

[0052] The decorative element 31 is fixed to the second jump ring 23. The decorative element 31 is an object that performs the decorative function, such as a gemstone.

[0053] As illustrated in FIG. 8, also in the necklace 101, the cross-section of the first jump ring 21 and the cross-section of the second jump ring 23 are each formed in the tapered shape that protrudes at the distal angle of 60° to 90° to the inner side (center of circumference). With this, the inner periphery of the first jump ring 21 and the inner periphery of the second jump ring 23 are linked to each other at a point, that is, at the point-link portions 41. Thus, the second jump ring 23 and the decorative element 31 dangle about the Z-axis, the X-axis, and the Y-axis (three axes) relative to the point-link portions 41. This allows a dangling pattern to be more diversified than that of the pendant having the double-ring mechanism described in "Background Art."

[0054] Further, in the necklace 101, a simple dangling mechanism can be obtained by engaging the first jump ring 21 and the second jump ring 23 with each other.Reference Signs List
