Description
本発明は、ファセット・カットされた宝石を保持する宝石保持具と、宝石保持具によって宝石が保持された装飾具に関するものである。 The present invention relates to a jewel holder for holding faceted cut jewels, and a decorative tool in which jewels are held by the jewel holder.
一般的な宝石保持具は複数の爪で宝石を固定しているが、宝石の面が複数の爪で隠れてしまうことによって輝きが減じてしまうという問題がある。これに対し、特許文献１に記載される宝石保持具は、ファセット・カットされた宝石のテーブル（天井部の平らな面）とクラウン（上部の側面）に当接する爪、パビリオン（下部の側面）に当接する当接部、及び、キューレット（下部の頂点）を支持する支持座を一体的に形成した構造を有している。この構造によって、複数の爪で固定するよりも宝石の面を露呈させつつ、宝石を確実に保持している。 A general jewel holder holds a jewel with a plurality of nails, but there is a problem that the brightness of the jewel is reduced by hiding the surface of the jewel with a plurality of nails. On the other hand, the jewel holder described in Patent Document 1 is a facet-cut jewel table (flat surface of the ceiling part) and a claw abutting against a crown (upper side face), a pavilion (lower side face). And a support seat that supports the curette (lower apex) are integrally formed. With this structure, the jewel is securely held while exposing the surface of the jewel rather than fixing with a plurality of claws.
ところが、上述した特許文献１に記載される宝石保持具では、宝石のクラウンに形成されたファセットに爪が当接しているため、クラウンのファセットの一部が爪によって隠れてしまう。宝石のクラウンに形成されるファセットは、宝石の上側に向かって放射状に光を反射させる面であることから、宝石の見た目にとってとりわけ重要であり、このファセットが爪で隠れてしまうと、見た目の輝きが減じてしまうという問題がある。 However, in the jewelry holder described in Patent Document 1 described above, since the claws are in contact with the facets formed on the crown of the gem, a part of the facets of the crown is hidden by the claws. The facets formed on the crown of the gem are particularly important for the gem's appearance because they reflect light radially towards the top of the gem, and if this facet is hidden by the nails, it looks bright There is a problem that decreases.
また、上述した特許文献１に記載される宝石保持具では、宝石のテーブルからクラウンにまたがって爪が当接していることから、クラウンのファセットとテーブル面とのなす角度に合わせて爪の２つの当接面を加工する必要がある。そのため、クラウンのファセットとテーブル面とのなす角度が宝石の種類ごとに異なる場合、同じ宝石保持具を流用することができなくなり、コストが高くなるという問題も生じる。 Moreover, in the jewelry holder described in Patent Document 1 described above, since the claws are in contact with the crown from the gem table, the two claws are adjusted in accordance with the angle between the facet of the crown and the table surface. It is necessary to process the contact surface. For this reason, when the angle formed between the facet of the crown and the table surface is different for each type of jewel, the same jewel holder cannot be used, resulting in a problem of increased cost.
本発明はかかる事情に鑑みてなされたものであり、その目的は、宝石の輝きを減じ難くすることができる宝石保持具と、そのような宝石保持具を備えた装飾具を提供することにある。 This invention is made | formed in view of this situation, The objective is to provide the jewelry holding tool which can make it hard to reduce the brightness of jewelry, and the ornament provided with such a jewelry holder. .

Moreover, FIG. 6 is sectional drawing in the AA line of a front view.
本実施形態に係る装飾具は、ファセットカットされた宝石１０と、この宝石１０を保持する宝石保持具２０とを有する。
宝石１０は、底面を共有する２つの錐体状の部分（クラウン１１、パビリオン１２）を備える。上側の錐体であるクラウン１１の側面と、下側の錐体であるパビリオン１２の側面には、それぞれ複数のファセット４，５が形成される。クラウン１１は、底面と平行な面によって頂点側を切り取られた形状になっており、その切断部分にファセットとしてのテーブル２が形成される。
ここで、クラウン１１は、本発明における上側部の一例である。
パビリオン１２は、本発明における下側部の一例である。
テーブル２は、本発明における天面の一例である。
The ornament according to the present embodiment includes a faceted jewel 10 and a jewel holder 20 that holds the jewel 10.
The jewel 10 includes two cone-shaped portions (crown 11 and pavilion 12) sharing the bottom surface. A plurality of facets 4 and 5 are formed on the side surface of the crown 11 that is the upper cone and the side surface of the pavilion 12 that is the lower cone. The crown 11 has a shape in which the apex side is cut off by a plane parallel to the bottom surface, and a table 2 as a facet is formed at the cut portion.
Here, the crown 11 is an example of an upper portion in the present invention.
The pavilion 12 is an example of the lower side part in this invention.
The table 2 is an example of the top surface in the present invention.
宝石保持具２０は、パビリオン１２の尖った頂点部分であるキューレット６を支持する台座部２１と、クラウン１１のテーブル２に当接する上側爪部２２と、パビリオン１２の側面に形成されたファセット５に当接する下側爪部２３とを有する。
台座部２１は、本発明における台座部の一例である。
上側爪部２２は、本発明における上側爪部の一例である。
下側爪部２３は、本発明における下側爪部の一例である。
The jewel holder 20 includes a pedestal portion 21 that supports the curette 6, which is a pointed apex portion of the pavilion 12, an upper claw portion 22 that contacts the table 2 of the crown 11, and a facet 5 formed on the side surface of the pavilion 12. And a lower claw portion 23 that comes into contact with.
The pedestal portion 21 is an example of a pedestal portion in the present invention.
The upper claw part 22 is an example of the upper claw part in the present invention.
The lower claw part 23 is an example of a lower claw part in the present invention.
台座部２１は、お椀型の形状に形成されており、その椀形状の内側には湾曲面２６が設けられている。湾曲面２６は、パビリオン１２の頂点に近い部分を囲むようにして凹状に湾曲する。湾曲面２６の外縁を形成する台座部２１の縁部は、湾曲面２６の底部を宝石１０のテーブル２側から透視する方向より見た場合、ほぼ円形のリング状に形成される（図４）。また、台座部２１の縁部は、湾曲面２６の底部（最も底の部分）に対して、リング形状の略全周にわたって高さが均一になるように形成される（図１、図２）。 The pedestal portion 21 is formed in a bowl shape, and a curved surface 26 is provided inside the bowl shape. The curved surface 26 is curved in a concave shape so as to surround a portion close to the apex of the pavilion 12. The edge portion of the pedestal portion 21 that forms the outer edge of the curved surface 26 is formed in a substantially circular ring shape when the bottom portion of the curved surface 26 is viewed from the table 2 side of the jewel 10 (FIG. 4). . Further, the edge of the pedestal 21 is formed so as to have a uniform height over substantially the entire circumference of the ring shape with respect to the bottom (the bottommost part) of the curved surface 26 (FIGS. 1 and 2). .
台座部２１は、湾曲面２６の底部から離間するにつれて厚みを増すように形成される（図６）。すなわち、湾曲面２６における台座部２１の厚さは底部において最も薄く、底部から縁部に向かって徐々に厚みが増す。具体的には、例えば底部における厚みが０．９ｍｍ程度、縁部における厚みが１．１ｍｍ程度であり、その中間部分の厚みは底部から縁部に向かって連続的に増える。 The pedestal 21 is formed so as to increase in thickness as the distance from the bottom of the curved surface 26 increases (FIG. 6). That is, the thickness of the pedestal 21 on the curved surface 26 is the thinnest at the bottom, and the thickness gradually increases from the bottom toward the edge. Specifically, for example, the thickness at the bottom is about 0.9 mm and the thickness at the edge is about 1.1 mm, and the thickness of the intermediate portion continuously increases from the bottom toward the edge.
台座部２１の底部の略中央には、宝石１０のパビリオン１２のキューレット６が嵌入する嵌入孔２７が形成される（図６）。図５，図６の例において、嵌入孔２７は、台座部２１の内側の湾曲面２６から外側の面に向かって貫通している。なお、嵌入孔２７は、キューレット６を台座部２１の底部において支持できるものであればよいので、キューレット６を嵌入するのに十分に深さを確保できる場合は、台座部２１の外側の面に貫通しない凹状の形態でもよい。 An insertion hole 27 into which the curette 6 of the pavilion 12 of the jewel 10 is inserted is formed in the approximate center of the bottom of the pedestal 21 (FIG. 6). 5 and 6, the insertion hole 27 penetrates from the inner curved surface 26 of the pedestal portion 21 toward the outer surface. In addition, since the insertion hole 27 should just be what can support the curette 6 in the bottom part of the base part 21, when sufficient depth can be ensured in order to insert the curette 6, the outer side of the base part 21 is sufficient. A concave shape that does not penetrate the surface may be used.
図８は、嵌入孔２７の一例を示す図である。図８（Ａ）は湾曲面２６の側から見た図であり、図８（Ｂ）は断面図である。
嵌入孔２７は、例えば図８において示すように、キューレット６の稜線と嵌合する複数の溝２７１を有する。キューレット６の近傍には、複数のファセット５が形成されており、これらのファセット５の境界をなす複数の稜線が頂点から放射状に延びている（図５）。嵌入孔２７に形成された複数の溝２７１は、これらの稜線と嵌合する。
FIG. 8 is a diagram illustrating an example of the insertion hole 27. 8A is a view seen from the curved surface 26 side, and FIG. 8B is a cross-sectional view.
For example, as shown in FIG. 8, the fitting hole 27 has a plurality of grooves 271 that fit into the ridgeline of the curette 6. A plurality of facets 5 are formed in the vicinity of the curette 6, and a plurality of ridge lines forming boundaries of these facets 5 extend radially from the apexes (FIG. 5). The plurality of grooves 271 formed in the insertion hole 27 are fitted with these ridge lines.
また、嵌入孔２７は、湾曲面２６から深くなるにつれて径が小さくなるように形成される。キューレット６と接する嵌入孔２７の内壁は、中心に向かってテーパー状に傾いている。 Further, the insertion hole 27 is formed so that the diameter decreases as the depth increases from the curved surface 26. The inner wall of the insertion hole 27 in contact with the curette 6 is inclined in a tapered shape toward the center.
上側爪部２２は、テーブル２の中央部から縁部へ向かって線状若しくは帯状に延びた領域に当接する。上側爪部２２の上述した当接部分は、テーブル２の面内に含まれており、クラウン１１のファセット４には及んでいない。また図１の例において、上側爪部２２は、テーブル２との当接部分に近いほど厚み（図１における左右方向の厚み、すなわち、テーブル２の面と平行な方向における厚み）が薄くなる刃状の形状を有する。 The upper claw portion 22 abuts on a region extending in a linear shape or a strip shape from the center portion of the table 2 toward the edge portion. The above-described contact portion of the upper claw portion 22 is included in the surface of the table 2 and does not reach the facet 4 of the crown 11. In the example of FIG. 1, the upper claw portion 22 is a blade whose thickness ( thickness in the left-right direction in FIG. 1, that is, thickness in a direction parallel to the surface of the table 2) becomes thinner as it comes closer to the contact portion with the table 2 . It has a shape.
下側爪部２３は、パビリオン１２の側面に形成される１つ若しくは複数のファセット５に当接しており、その当接部分はパビリオン１２の側面の範囲内に含まれる。すなわち、下側爪部２３の当接部分は、クラウン１１とパビリオン１２との境界をなす帯状領域（ガードル３）や、クラウン１１の側面まで及んでいない。 The lower claw portion 23 is in contact with one or a plurality of facets 5 formed on the side surface of the pavilion 12, and the contact portion is included in the range of the side surface of the pavilion 12. That is, the contact portion of the lower claw portion 23 does not extend to the belt-like region (girdle 3) that forms the boundary between the crown 11 and the pavilion 12 or the side surface of the crown 11.
上側爪部２２とテーブル２との当接部分が線状若しくは帯状に延びる方向と、パビリオン１２の錐体形状の中心軸から下側爪部２３の当接部分へ向かう方向とは、ほぼ平行である。 The direction in which the contact portion between the upper claw portion 22 and the table 2 extends linearly or in a strip shape is substantially parallel to the direction from the central axis of the cone shape of the pavilion 12 toward the contact portion of the lower claw portion 23. is there.
上述した台座部２１、上側爪部２２及び下側爪部２３は、貴金属等の材料によって一体形成されており、上側爪部２２と下側爪部２３とをつなぐ部分２４は、クラウン１１のファセット４から適度な距離を空けて離隔する形状に形成される。図６の例では、上側爪部２２の当接部分と下側爪部２３の当接部分との間のつなぎ部分２４が、クラウン１１の側面を避けるようにしてアーチ状に曲がっている。 The pedestal portion 21, the upper claw portion 22, and the lower claw portion 23 described above are integrally formed of a material such as a noble metal, and the portion 24 that connects the upper claw portion 22 and the lower claw portion 23 is a facet of the crown 11. It is formed in a shape that is separated from 4 by an appropriate distance. In the example of FIG. 6, the connecting portion 24 between the contact portion of the upper claw portion 22 and the contact portion of the lower claw portion 23 is bent in an arch shape so as to avoid the side surface of the crown 11.
また、宝石保持具２０は、図示しないチェーンや紐、リングなどを貫通させて装飾具全体を吊り下げることができるようにするための環状部２５を有する。この環状部２５も、上述した台座部２１、上側爪部２２、下側爪部２３と一体形成される。 Moreover, the jewelry holder 20 has an annular portion 25 for allowing a chain, a string, a ring, and the like (not shown) to pass therethrough so that the entire ornament can be suspended. The annular portion 25 is also integrally formed with the pedestal portion 21, the upper claw portion 22, and the lower claw portion 23 described above.
以上のような構成を有する宝石保持具２０によれば、テーブル２に当接する上側爪部２２とパビリオン１２のファセット５に当接する下側爪部２３とをつなぐ部分２４がクラウン１１のファセット４から適度な距離を隔てて離隔しており、クラウン１１の前面が爪によって隠れない構造となっている。そのため、宝石１０の上側のクラウン１１に形成されるファセット４の反射光を十分に周囲へ放射させることができ、宝石１０の輝きを減じ難くすることができる。 According to the jewelry holder 20 having the above-described configuration, the portion 24 that connects the upper claw portion 22 that abuts the table 2 and the lower claw portion 23 that abuts the facet 5 of the pavilion 12 from the facet 4 of the crown 11. It is separated by an appropriate distance and has a structure in which the front surface of the crown 11 is not hidden by the claws. Therefore, the reflected light of the facet 4 formed on the crown 11 on the upper side of the jewel 10 can be sufficiently emitted to the surroundings, and the shine of the jewel 10 can be hardly reduced.
また、上述した宝石保持具２０によれば、宝石１０の上側に形成される平らなテーブル２を上側爪部２２によって押え、宝石１０の下側のキューレット６を台座部２１によって支持することにより、宝石１０の錐体形状の中心軸と平行な垂直方向において宝石１０を強固に挟み込むことができる。また、宝石１０のパビリオン１２のファセット５を下側爪部２３によって押えることによって、宝石１０の水平方向への動きを効果的に抑制することができ、宝石１０を確実に保持できる。 Further, according to the above-described jewel holder 20, the flat table 2 formed on the upper side of the jewel 10 is pressed by the upper claw portion 22, and the curette 6 on the lower side of the jewel 10 is supported by the pedestal portion 21. The jewel 10 can be firmly sandwiched in the vertical direction parallel to the central axis of the cone shape of the jewel 10. Further, by pressing the facet 5 of the pavilion 12 of the jewel 10 with the lower claw portion 23, the movement of the jewel 10 in the horizontal direction can be effectively suppressed, and the jewel 10 can be reliably held.
上述した宝石保持具２０によれば、椀形状の台座部２１における湾曲面２６の厚さが底部から縁部に向かって厚みを増すように形成されている。これにより、台座部２１の縁部に十分な厚みを持たせて所望の構造強度を保つことができるとともに、湾曲面２６の底の厚さをやや薄くして使用材料（貴金属等）の量を削減することができる。また、台座部２１の縁部から底部に向かって連続的に厚みが薄くなっていることから、上側爪部２２による垂直方向の押圧によって宝石１０のキューレット６が嵌入孔２７へ押し込まれた場合に、底面の領域で弾性的な変形が生じ易くなり、宝石１０の保持の緩みを効果的に抑制することができる。 According to the jewel holder 20 described above, the thickness of the curved surface 26 of the bowl-shaped pedestal portion 21 is formed so as to increase from the bottom toward the edge. Accordingly, the edge of the pedestal portion 21 can have a sufficient thickness to maintain a desired structural strength, and the thickness of the bottom of the curved surface 26 can be slightly reduced to reduce the amount of material (noble metal, etc.) used. Can be reduced. In addition, since the thickness continuously decreases from the edge of the pedestal portion 21 toward the bottom, the curette 6 of the jewel 10 is pushed into the insertion hole 27 by the vertical pressing by the upper claw portion 22. In addition, elastic deformation is likely to occur in the region of the bottom surface, and the loose holding of the jewel 10 can be effectively suppressed.
更に、上述した宝石保持具２０によれば、椀状の台座部２１の湾曲面２６によってパビリオン１２の頂点に近い部分が囲まれていることにより、宝石１０の下側（パビリオン１２）の部分に物が直接当たり難くなる。そのため、この部分に物体が衝突等することによって台座部２１の嵌入孔２７から宝石１０のキューレット６が外れてしまうことを効果的に防止できる。 Furthermore, according to the jewel holder 20 described above, a portion close to the apex of the pavilion 12 is surrounded by the curved surface 26 of the bowl-shaped pedestal portion 21, so that the lower portion of the jewel 10 (pavilion 12) Things are hard to hit directly. Therefore, it is possible to effectively prevent the curette 6 of the jewel 10 from being detached from the insertion hole 27 of the pedestal portion 21 due to an object colliding with this portion.
また、上述した宝石保持具２０によれば、台座部２１の湾曲面２６がパビリオン１２のファセット５から離間しているため、外光が湾曲面２６とパビリオン１２の間に回り込み易くなり、湾曲面２６で反射した光によってパビリオン１２のファセット５を輝かせることができる。 Further, according to the jewelry holder 20 described above, since the curved surface 26 of the pedestal portion 21 is separated from the facet 5 of the pavilion 12, external light can easily flow between the curved surface 26 and the pavilion 12, and the curved surface. The facet 5 of the pavilion 12 can be shined by the light reflected at 26.
加えて、上述した宝石保持具２０によれば、キューレット６の近傍に形成されたファセット５の境界の稜線と嵌合する溝２７１が嵌入孔２７の内面に形成されているため、嵌入孔２７に嵌入した状態でキューレット６が回転することを防ぐことができる。これにより、宝石１０が物体に触れても回転し難くなるので、上側爪部２２や下側爪部２３の当接部のずれによる宝石１０の脱落を生じ難くすることができる。 In addition, according to the jewel holder 20 described above, since the groove 271 that fits the ridgeline at the boundary of the facet 5 formed in the vicinity of the curette 6 is formed on the inner surface of the fitting hole 27, the fitting hole 27. It is possible to prevent the curette 6 from rotating in the state of being inserted into the. Thereby, since it becomes difficult to rotate even if the jewel 10 touches an object, it is possible to make it difficult for the jewel 10 to fall off due to the displacement of the contact portions of the upper claw portion 22 and the lower claw portion 23.
また、上述した宝石保持具２０によれば、嵌入孔２７の内面がキューレット６に合わせてテーパー状に形成されており、キューレット６の稜線と溝２７１とを十分な長さで嵌合させることができるので、宝石１０をより回転し難くすることができる。 Moreover, according to the jewelry holder 20 described above, the inner surface of the insertion hole 27 is formed in a tapered shape in accordance with the curette 6, and the ridge line of the curette 6 and the groove 271 are fitted with a sufficient length.
