Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, as materials used for the annular part of a ring, materials other than metals have been studied. For example, studies on annular parts made of ceramics and plastics have been advanced. In a ring in which a decorative body is attached to an annular part made of ceramics or plastic, there has been room for studying the material of the fixing part for attaching the decorative body.

[0006] When forming an annular portion with ceramics, it is conceivable to apply ceramics as the material of the fixing portion. However, it is difficult to configure the fixing portion with ceramics. Even if the fixing portion could be configured with ceramics, it would be difficult to join the ceramic annular portion and the ceramic fixing portion. Further, when producing a plastic annular portion and a plastic fixing portion and joining the plastic annular portion and the plastic fixing portion, the strength may not be sufficient. The metal fixing portion has high strength, but the metal fixing portion cannot be fixed to the ceramic or plastic annular portion by brazing or the like.

[0007] An object of the present invention is to provide a frame capable of firmly fixing a metal fixing portion to an annular portion even if the annular portion is made of ceramics or plastic, and a ring including the frame.

Modes for Carrying Out the Invention

[0025] [Hollow Frame] The first aspect of the present invention is a hollow frame. The hollow frame according to the first aspect of the present invention is a frame that serves as a support for a decorative body. The hollow frame has a through hole penetrating the outer peripheral surface and the inner peripheral surface, and includes a ceramic or plastic annular portion, and a metal fixing portion having a shaft portion and a head portion and inserted into the through hole. The shaft portion protrudes from the outer peripheral surface, and the head portion protrudes from the inner peripheral surface. In one aspect, it is preferable that the annular part of the empty frame is made of ceramics. In one aspect, it is also preferable that the major axis of the head is larger than the major axis of the shaft part in the empty frame. In one aspect, it is also preferable that the empty frame includes an adhesive for bonding the annular part and the fixing part inside the through hole. In one aspect, it is also preferable that the fixing part of the empty frame is engraved.

[0026] <First Embodiment> Hereinafter, an embodiment which is a preferred example of the present invention will be described with reference to the drawings. The present invention is not limited to the content of the embodiment. In the drawings, there are parts shown enlarged or reduced for ease of explanation.

[0027] In FIGS. 1, 2, 3, and 4, an example of the empty frame according to the present embodiment is schematically shown. FIG. 1 is a schematic perspective view showing an example of the empty frame according to the present embodiment, FIG. 2 is a schematic front view showing an example of the empty frame according to the present embodiment, FIG. 3 is a schematic side view showing an example of the empty frame according to the present embodiment, and FIG. 4 is a schematic enlarged view showing a part where the fixing part is inserted into the through hole in an example of the empty frame according to the present embodiment. In FIGS. 1 to 4, a ring-shaped empty frame for a ring is shown as an example of the empty frame.

[0028] As shown in FIGS. 1 to 4, the empty frame 100 includes a ring 10 as an example of the annular part and a fixing pin 20 as an example of the fixing part. In the empty frame 100, the ring 10 is made of ceramics and has an annular shape. The ceramics that is the material constituting the ring 10 is not particularly limited. As the ceramics that is the material constituting the ring 10, for example, at least one selected from the group consisting of zirconia and alumina is used. For the material constituting the ring 10, it is preferable to use, for example, ceramics having a Mohs hardness of 8 or more and 10 or less and a Young's modulus of 120 GPa or more and 400 GPa or less.

[0029] When the ring 10 is cut along the width direction, the cross-sectional shape is formed such that both ends in the width direction are rounded on both the outer peripheral surface and the inner peripheral surface. The ring 10 is a member for fitting on a finger, and the inner diameter of the ring 10 is formed to be a size that can be attached to and detached from a finger. The ring 10 is provided with a through hole 13 that penetrates the outer peripheral surface 11 and the inner peripheral surface 12 of the ring 10, and the through hole 13 is formed to be a size into which a fixing pin 20 can be inserted. The major axis of the through hole 13 is not particularly limited as long as the fixing pin 20 can be inserted. Preferably, the major axis of the through hole 13 is formed in a range of, for example, 0.6 mm or more and 1.2 mm or less so that the fixing pin 20 can be inserted and the decorative body can be supported. In the empty frame 100, since the opening shape of the through hole 13 is formed in a shape close to a circle, the major axis of the through hole 13 is a dimension corresponding to the diameter of the through hole 13. In this specification, the major axis refers to the length of the longest part in the radial direction.

[0030] The fixing pin 20 is a member for fixing the decorative body. The fixing pin 20 is inserted into the through hole 13 provided in the ring 10 so as to penetrate the outer peripheral surface and the inner peripheral surface of the ring 10. The fixing pin 20 is made of metal. Since the fixing pin 20 is made of metal, the fixing pin 20 has high strength. The fixing pin 20 may be made of, for example, pure gold or a metal made of an alloy containing gold. In this specification, pure gold is not limited to gold with a gold purity of 99.99% or more, but is a concept that includes gold with a gold purity of 99.00% or more. In this specification, an alloy containing gold refers to a concept that indicates an alloy with a gold purity of less than 99.00%. In the empty frame 100, as shown in FIG. 4, the fixing pin 20 is made of 18-karat gold. The fixing pin 20 can be produced, for example, by cold forging (so-called header processing) in which pressure is applied to a wire rod that is the material of the fixing pin 20 at room temperature. The fixing pin 20 can obtain a high-strength fixing pin 20, for example, by being produced by header processing.

[0031] As shown in FIG. 2, the fixing pin 20 inserted into the through hole 13 extends from the second end portion 20B to the first end portion 20A. The fixing pin 20 includes a shaft portion 21 on the first end portion 20A side and a head portion 22 having a major axis larger than the major axis of the shaft portion 21 on the second end portion 20B side. Since the major axis of the head portion 22 is larger than the major axis of the shaft portion 21, it is formed to have a size larger than the major axis of the through hole 13. The shaft portion 21 protrudes from the outer peripheral surface 11 through the inside of the through hole 13 from the inner peripheral surface 12 of the ring 10 and extends toward the first end portion 20A. The head portion 22 protrudes from the inner peripheral surface 12 and extends from the inner peripheral surface 12 toward the second end portion 20B. At least a part of the surface of the head portion 22 on the first end portion 20A side is in contact with the inner peripheral surface 12.

[0032] The length of the fixing pin 20 is not particularly limited as long as it is a dimension that penetrates the ring 10. The length of the fixing pin 20 is preferably formed, for example, in the range of 5 mm or more and 15 mm or less. The axial dimension of the shaft portion 21 is formed to be longer than the axial dimension of the head portion 22. Here, the length of the fixing pin 20 represents the entire length of the fixing pin 20 and refers to the axial length. The axial direction is the direction connecting the first end portion 20A and the second end portion 20B.

[0033] In the empty frame 100, the shape of the shaft portion 21 is cylindrical and has a substantially constant diameter over the entire axial direction. Since the shape of the shaft portion 21 is formed in a cylindrical shape, the major axis of the shaft portion 21 is a dimension corresponding to the diameter of the shaft portion 21. The diameter of the shaft portion 21 is formed to be slightly shorter than the major axis of the through hole 13 so as to be able to be inserted into the through hole 13, either in contact with the inner wall of the through hole 13 or not in contact with the inner wall of the through hole 13. The diameter of the shaft portion 21 may be formed, for example, in the range of 0.6 mm or more and 1.2 mm or less, and specifically, for example, in the range of 0.58 mm or more and 1.18 mm or less.

[0034] As shown in FIGS. 2 and 4, the planar shape of the head 22 viewed in plan from the second end portion 20B is a circular shape, and when the head 22 is viewed in a cut-along axial direction, it has an arc-shaped shape. In the head 22, the surface on the side of the second end portion 20B, which is the surface where the engraving is provided, presents a curved surface protruding toward the outer side in the axial direction (the direction toward the second end portion 20B), and the surface on the radial side of the head 22 has a rounded shape that gradually expands in the radial direction from the second end portion 20B toward the first end portion 20A. That is, the radial dimension of the head 22 is formed so as to have a portion that gradually increases from the second end portion 20B side toward the first end portion 20A side, and has a portion that becomes larger than the dimension of the major axis of the shaft portion 21. The radial direction is a direction orthogonal to the axial direction and is a direction along the major axis direction of the shaft portion and the head. The dimension of the major axis of the head 22 is not particularly limited. The major axis of the head 22 is preferably formed in the range of, for example, 1.0 mm or more and 2.0 mm or less. Here, the major axis of the head 22 refers to the dimension of the longest portion in the radial direction of the head 22. In the blank 100, the major axis of the head 22 is the longest around the first end portion 20A side of the head 22 and corresponds to the dimension around the first end portion 20A side of the head 22.

[0035] As shown in FIGS. 1, 2, and 4, the surface of the fixing pin 20 is engraved, and engravings are provided on the side surface of the shaft portion 21 and the top of the head 22, respectively. In the fixing pin 20, the name of the noble metal ingot is engraved on the top of the head 22, and the name of the manufacturer is engraved on the side surface of the shaft portion 21. The engraving is not limited to this, and the desired engraving can be performed. The engraving may be provided only on the side surface of the shaft portion 21 or only on the top of the head 22. The engraving can be formed on the surface of the fixing pin 20, for example, by performing laser processing.

[0036] A preferred manufacturing method of the empty frame 100 includes, as an example, the following manufacturing method. First, a ceramic ring 10 having a target shape is manufactured so as to include a through hole 13 penetrating from the outer peripheral surface 11 to the inner peripheral surface 12. The ceramic ring 10 having the through hole 13 can be obtained, for example, by providing a hole penetrating the ring 10 in a ceramic precursor for obtaining the ring 10 and then firing the ceramic precursor. In addition, after manufacturing the ceramic ring 10 having the target shape, the through hole 13 can also be provided. Separately, a metal fixing pin 20 having a shaft portion 21 with a major diameter that can be inserted into the through hole 13 and a head portion 22 having a major diameter larger than the major diameter of the shaft portion 21 is manufactured by header processing or the like. Then, the empty frame 100 is obtained by inserting the fixing pin 20 from the inner peripheral surface 12 side into the through hole 13 of the ceramic ring 10 so that the shaft portion 21 protrudes from the outer peripheral surface 11 and the head portion 22 contacts the inner peripheral surface 12.

[0037] In the empty frame 100, in order to more firmly fix the fixing pin 20 to the ring 10, an adhesive for bonding the ring 10 and the fixing pin 20 is used inside the through hole 13. The adhesive is not particularly limited as long as it can bond the ring 10 and the fixing pin 20, and known adhesives can be applied. Examples of the adhesive include two-component curable adhesives, and specifically, two-component curable epoxy adhesives and the like. The two-component curable epoxy adhesive is not particularly limited. For example, the main agent may be an epoxy resin and the curing agent may be a polythiol compound. If there is no concern about the influence on the decorative body, other adhesives (for example, thermosetting adhesives and ultraviolet curable adhesives) can also be used in addition to the two-component curable epoxy adhesive.

[0038] (Operational Effects of the First Embodiment) According to this embodiment, the following operational effects can be achieved. (1) Even if the ring 10 is made of ceramics, a through hole 13 is provided in the ring 10, and a fixing pin 20 made of a metal different from that of the ring 10 is inserted into the through hole 13, so that the fixing pin 20 can be firmly fixed to the ring 10. (2) The fixing pin 20 has a shaft portion 21 and a head portion 22, and the major axis of the head portion 22 is larger than the major axis dimension of the shaft portion 21, so that the major axis of the head portion 22 is larger than the major axis of the through hole 13. Therefore, even when the fixing pin 20 is inserted into the through hole 13 of the ring 10, the fixing pin 20 can be firmly fixed, and the fixing pin 20 can be prevented from falling off the ring 10. (3) In the cross-sectional shape of the head portion 22 of the fixing pin 20 in the axial direction, the side surface of the head portion 22 is curved outward, and has an arc shape in which the axial dimension gradually increases. By this, even when a finger is inserted into the ring 10 as an annular portion, the feeling of discomfort is suppressed from being generated. (4) By applying an engraving to the fixing pin 20, various information such as the material information of the fixing pin 20, the manufacturer information of the blank 100, and the brand information of the blank 100 can be specified. For example, it becomes possible to enhance the commercial value of the blank and the ring using the blank. (5) Since the blank 100 has an adhesive applied inside the through hole 13 for adhering the ring 10 and the fixing pin 20, the fixing pin 20 can be fixed more firmly.

[0039] [Ring] The second aspect of the present invention is a ring. The ring according to the second aspect of the present invention includes a decorative body and a blank according to the first aspect, and the decorative body is fixed by the fixing portion. In one aspect, it is preferable that the decorative body has a non-through hole portion, and the shaft portion of the fixing portion is inserted into the hole portion. In one aspect, it is also preferable that the decorative body is fixed to the fixing portion via an adhesive. In one aspect, it is preferable that the decorative body is gemstones. In one aspect, it is also preferable that the gemstones of the ring are pearls. In one aspect, it is also preferable that the decorative body of the ring is made of plastic or rubber.

[0040] <Second Embodiment> Hereinafter, an embodiment which is a preferred example of the present invention will be described with reference to the drawings. The present invention is not limited to the content of the embodiment. In the drawings, there are parts shown enlarged or reduced for ease of explanation. In the following description, the parts related to the differences from the first embodiment will be mainly described, and the same reference numerals will be given to the same configurations as those in the first embodiment, and the redundant explanations will be omitted or simplified.

[0041] Examples of the ring according to the present embodiment are schematically shown in FIGS. 5, 6, and 7. FIG. 5 is a schematic perspective view showing an example of the ring according to the present embodiment, FIG. 6 is a schematic front view showing an example of the ring according to the present embodiment, and FIG. 7 is a schematic plan view showing an example of the ring according to the present embodiment.

[0042] As shown in FIGS. 5, 6, and 7, the ring 300 includes an empty frame 100 and a decorative body 30. The empty frame 100 is the empty frame 100 described in the first embodiment. In the ring 300, a spherical pearl is used for the decorative body 30. Note that any imitation pearl including natural pearls, cultured pearls, and plastic-made pearls can be used as the pearl. As shown in FIG. 7, the decorative body 30 is selected to have a maximum dimension in the radial direction larger than the dimension in the width direction of the ring 10 and is attached to the empty frame 100. That is, the ring 300 includes a pearl having a pearl diameter larger than the width dimension of the ring 10. The ring 300 is used by inserting a finger into the ring 10, and usually, when a finger is inserted into the ring 10, the decorative body 30 is used so as to face the back of the hand.

[0043] As shown in FIGS. 6 and 7, the ornament 30 has a non-penetrating hole 31 near the center in the radial direction of the ornament 30. In the ring 300, the ornament 30 is supported by the empty frame 100 by inserting and fixing the shaft portion 21 of the fixing pin 20 into the hole 31. The inner diameter of the hole 31 only needs to allow the insertion of the shaft portion 21, and for example, it can be in the range of 0.6 mm or more and 1.2 mm or less. From the viewpoint that the ornament 30 can be firmly supported by the empty frame 100, the depth of the hole 31 is, for example, a dimension such that the length of the shaft portion 21 reaches a range of 20% or more and 90% or less with respect to the size of the entire ornament 30, and may also be a dimension that reaches a range of 50% or more and 90% or less, and preferably a dimension that reaches a range of 70% or more and 85% or less. In the ring 300, since the ornament 30 is a spherical pearl, the depth of the hole 31 is preferably formed to be, for example, about two-thirds of the pearl diameter. The hole 31 can be formed by a known hole drilling device.

[0044] In the ring 300, an adhesive is applied between the hole 31 of the ornament 30 and the shaft portion 21 of the fixing pin 20, and the ornament 30 and the fixing pin 20 are fixed via the adhesive. Since the ornament 30 is fixed to the empty frame 100 by the adhesive, it is possible to prevent the ornament 30 from falling off the empty frame 100. The adhesive is not particularly limited, and a known adhesive can be applied. Examples of the adhesive include two-component curable adhesives, and specifically, two-component curable epoxy adhesives and the like. In the ring 300, since a pearl is applied to the ornament 30, from the viewpoint of having little possibility of affecting the pearl, the adhesive is preferably a two-component curable epoxy adhesive. The two-component curable epoxy adhesive is not particularly limited, and for example, the main agent may be an epoxy resin and the curing agent may be a polythiol compound. In addition, when the ornament 30 is other than a pearl and the adhesive has a low possibility of affecting the ornament 30, other adhesives (for example, thermosetting adhesives and ultraviolet curable adhesives) can also be used in addition to the two-component curable epoxy adhesive.

[0045] (Function and Effect of the Second Embodiment) According to this embodiment, since the ring 300 includes the hollow frame 100, the same operational effects as those of (1) to (5) in the first embodiment can be achieved. Furthermore, according to this embodiment, the following operational effects can be achieved. (6) In the ring 300, since the hollow frame 100 in which the metal fixing pin 20 is inserted into the through hole 13 of the ceramic ring 10 is used, the decorative body 30 is firmly supported by the hollow frame 100. (7) In the ring 300, since the decorative body 30 is fixed to the hollow frame 100 via an adhesive, the decorative body 30 is more firmly supported by the hollow frame 100.

[0046] [Modifications of the Embodiment] As described above, the hollow frame according to the first embodiment and the ring according to the second embodiment have been described with reference to the drawings. However, the present invention is not limited to the foregoing embodiments, and modifications or improvements within the scope that can achieve the object of the present invention are included in the present invention.

[0047] For example, in the foregoing first and second embodiments, an example in which the ring 10 of the hollow frame 100 is made of ceramics has been described. However, the present invention is not limited to this, and it may be made of plastic.

[0048] For example, in the foregoing first and second embodiments, an example in which the fixing pin 20 included in the hollow frame 100 is made of 18K gold has been described. However, the present invention is not limited to this, and for example, it may be made of other metals such as 10K, 14K, 22K, and 24K (pure gold) gold or alloys containing gold, stainless steel, or brass.

[0049] For example, in the hollow frame 100 described in the foregoing first and second embodiments, when the ring 10 is cut along the width direction, the cross-sectional shape has been exemplified as a shape rounded near both ends in the width direction on both the outer peripheral surface and the inner peripheral surface. However, the present invention is not limited to this, and any known shape may be used.

[0050] For example, in the aforementioned first and second embodiments, the shape of the shaft portion 21 of the fixing pin 20 is cylindrical, the planar shape of the head portion 22 is circular, and the cross-sectional shape has an arc shape. However, the present invention is not limited thereto, and various shapes may be used. For example, the shape of the shaft portion 21 of the fixing pin 20 may have a polygonal prism, the planar shape of the head portion 22 may have a rectangle or a polygon, and the cross-sectional shape may have a rectangle. The head portion 22 preferably has a shape that does not cause a sense of discomfort even when a finger is inserted into the ring 10.

[0051] For example, in the aforementioned first and second embodiments, an example in which one fixing pin 20 is inserted into one through-hole 13 provided in the ring 10 has been described. However, the present invention is not limited thereto, and the empty frame 100 may include a ring 10 provided with a plurality of through-holes 13 and a plurality of fixing pins 20. In this case, the ring 10 may be provided with two or more through-holes 13, and the fixing pin 20 may be inserted into each of the plurality of through-holes 13. When the fixing pin 20 is inserted into each of the plurality of through-holes 13, a ring in which a plurality of decorative bodies 30 are fixed to the empty frame 100 can also be configured by inserting the shaft portion 21 of each fixing pin 20 into the hole portion 31 of the decorative body 30. Further, in the ring 300, when there are a plurality of decorative bodies 30, the plurality of decorative bodies 30 may be the same type of decorative body or different types of decorative bodies.

[0052] For example, in the aforementioned first and second embodiments, an example in which the fixing pin 20 includes one shaft portion 21 and the decorative body 30 is fixed to the empty frame 100 by inserting the shaft portion 21 into the hole portion 31 of the decorative body 30 has been described. However, the present invention is not limited thereto, and the shaft portion 21 of the fixing pin 20 may be branched to form a plurality of claw portions, and the decorative body 30 may be fixed by locking with the claw portions. Further, as described above, when an empty frame in which the fixing pin 20 is inserted into each of the plurality of through-holes 13 is configured, since there are a plurality of fixing pins 20, the plurality of fixing pins 20 may be formed in the shape of claw portions, and the decorative body 30 may be fixed by locking with the claw portions.

[0053] For example, in the aforementioned second embodiment, a spherical pearl was used as the ornament 30. However, the shape of the pearl is not limited to spherical, and various shapes can be adopted. Further, in the second embodiment, a pearl was cited as an example of the ornament 30, but it is not limited thereto.
