宝石支持台において、宝石の支持部分を細くするほど宝石の存在感を強調することができ、宝石に多くの光を届けて宝石に多くの輝きを与えることができる。しかし、支持部分を細くするほど宝石の支持の安定性や強度の低下を招く。 In the gemstone support stand, the thinner the support part of the gemstone, the more the presence of the gemstone can be emphasized, and more light can be delivered to the gemstone to give the gemstone more brilliance. However, the thinner the support part, the lower the stability and strength of the gemstone support.

本発明の目的は、宝石を確実に支持固定し、デザイン性に優れ、宝石の輝きを損なわない構造の宝石支持台を提供することである。 An object of the present invention is to provide a gemstone support base having a structure that securely supports and fixes a gemstone, has excellent design, and does not impair the brilliance of the gemstone.

本発明の一態様は、宝石を支持する宝石支持台であって、中央に開口部を有する環状部と、環状部の開口部側の縁から開口部の中央に向けて突出し、縁に沿って互いに間隔を空けて配置された複数本の支持片と、環状部から上方に延出し、開口部の周囲に配置される複数本の第１押さえ爪と、を備え、開口部に配置される宝石の下方を複数本の支持片で支持し、宝石の外周を前記複数本の第１押さえ爪によって押さえる宝石支持台である。 One aspect of the present invention is a gemstone support base for supporting a gemstone, which has an annular portion having an opening in the center and an annular portion that protrudes from the opening-side edge of the annular portion toward the center of the opening and along the edge. A gemstone arranged in the opening, comprising a plurality of support pieces arranged at intervals from each other and a plurality of first holding claws extending upward from the annular portion and arranged around the opening. It is a jewel support base that supports the lower part of the jewel with a plurality of support pieces and presses the outer periphery of the jewel with the plurality of first pressing claws.

このような構成によれば、環状部の開口部に宝石を配置すると、開口部の縁から延出する複数本の支持片によって宝石が下方から支持される。すなわち、宝石の下方の支持を複数本の支持片によって行うため、宝石を環状部の縁の全体で支持する必要がない。これにより、開口部を広くできるため、宝石の上方のみならず、下方や側方からも十分な光を届けることができる。さらに、宝石の外周が複数本の第１押さえ爪によって押さえられるため、宝石は確実に固定される。 According to such a configuration, when the jewel is placed in the opening of the annular portion, the jewel is supported from below by a plurality of support pieces extending from the edge of the opening. That is, since the lower support of the gemstone is performed by a plurality of support pieces, it is not necessary to support the gemstone over the entire edge of the annular portion. As a result, the opening can be widened, so that sufficient light can be delivered not only from above the jewel but also from below and from the side. Further, since the outer circumference of the jewel is pressed by the plurality of first pressing claws, the jewel is securely fixed.

上記宝石支持台において、複数本の支持片のそれぞれは、斜め上方に延出するよう設けられることが好ましい。これにより、環状部の開口部に配置された宝石は、開口部内で浮いているように支持される。 In the jewel support base, it is preferable that each of the plurality of support pieces is provided so as to extend diagonally upward. As a result, the gemstone placed in the opening of the annular portion is supported so as to float in the opening.

上記宝石支持台において、複数本の第１押さえ爪は、開口部の周囲に互いに等間隔で配置されることが好ましい。これにより、複数本の第１押さえ爪によって宝石をバランス良く押さえることができる。 In the jewel support base, it is preferable that the plurality of first pressing claws are arranged around the opening at equal intervals. As a result, the jewel can be pressed in a well-balanced manner by the plurality of first pressing claws.

上記宝石支持台において、環状部を上方からみて、複数本の支持片のそれぞれの両側に第１押さえ爪が配置されることが好ましい。これにより、１つの支持片と、この支持片に対して両側に配置される２つの第１押さえ爪とによって宝石を上下３点で支持することができる。 In the jewel support base, it is preferable that the first pressing claws are arranged on both sides of each of the plurality of support pieces when the annular portion is viewed from above. Thereby, the jewel can be supported at three points above and below by one support piece and two first holding claws arranged on both sides of the support piece.

上記宝石支持台において、第１押さえ爪には、宝石の外周部分が嵌め込まれる溝部が設けられることが好ましい。これにより、第１押さえ爪の溝部に宝石に外周部分が嵌め込まれ、確実に固定することができる。 In the jewel support base, it is preferable that the first pressing claw is provided with a groove into which the outer peripheral portion of the jewel is fitted. As a result, the outer peripheral portion is fitted into the jewel in the groove portion of the first pressing claw, and the jewel can be securely fixed.

上記宝石支持台において、環状部は、小宝石を配置する凹部を有していてもよい。これにより、環状部の開口部に配置される宝石を、凹部に配置される小宝石によって飾ることができる。 In the gem support, the annular portion may have a recess for arranging small gems. Thereby, the jewel arranged in the opening of the annular portion can be decorated with the small jewel arranged in the recess.

上記宝石支持台において、環状部を上方からみて、凹部における開口部とは反対側に設けられる第２押さえ爪を有し、第１押さえ爪と第２押さえ爪との間で、凹部に配置される小宝石の外周を押さえるようにしてもよい。これにより、宝石を押さえる第１押さえ爪を小宝石を押さえる爪として共用して、無駄なく宝石および小宝石を固定することができる。 The jewel support base has a second pressing claw provided on the side opposite to the opening in the recess when the annular portion is viewed from above, and is arranged in the recess between the first pressing claw and the second pressing claw. You may try to hold down the outer circumference of the small gem. As a result, the first holding claw that holds the jewel can be shared as the claw that holds the small jewel, and the jewel and the small jewel can be fixed without waste.

上記宝石支持台において、環状部は、複数の凹部および複数の第２押さえ爪を有していてもよい。これにより、宝石の周囲に複数の小宝石を配置することができる。 In the jewel support, the annular portion may have a plurality of recesses and a plurality of second pressing claws. This allows a plurality of small gems to be placed around the gem.

上記宝石支持台において、環状部を上方からみて、凹部の中央部分に孔が設けられることが好ましい。これにより、凹部に配置した小宝石の下方から十分な光を届けることができる。 In the gem support, it is preferable that a hole is provided in the central portion of the recess when the annular portion is viewed from above. As a result, sufficient light can be delivered from below the small gemstone placed in the recess.

本発明の一態様は、上記宝石支持台と、宝石支持台に配置された宝石と、を備える装飾具である。このような構成によれば、宝石を確実に固定しつつ、宝石の上方のみならず、下方や側方からも十分な光を届けることができる装飾具が実現する。 One aspect of the present invention is a decorative tool including the above-mentioned jewel support and a jewel arranged on the jewel support. According to such a configuration, a decorative tool capable of delivering sufficient light not only from above the jewel but also from below and from the side is realized while securely fixing the jewel.

本発明によれば、宝石を確実に支持固定し、デザイン性に優れ、宝石の輝きを損なわない構造の宝石支持台を提供することが可能となる。 According to the present invention, it is possible to provide a jewel support base having a structure that reliably supports and fixes a jewel, has excellent design, and does not impair the brilliance of the jewel.

In the present embodiment, for convenience of explanation, the side on which the jewel is placed is referred to as "upper". Gemstones also include imitation gemstones.

本実施形態に係る宝石支持台１は、中央に開口部１０ｈを有する環状部１０と、環状部１０の開口部１０ｈ側の縁から開口部１０ｈの中央に向けて突出する複数本の支持片２０と、環状部１０から上方に延出する第１押さえ爪３１と、を備える。 The jewel support stand 1 according to the present embodiment has an annular portion 10 having an opening 10h in the center, and a plurality of support pieces 20 projecting from the edge of the annular portion 10 on the opening 10h side toward the center of the opening 10h. And a first pressing claw 31 extending upward from the annular portion 10.

環状部１０は、開口部１０ｈに宝石Ｓ１を配置した状態で宝石Ｓ１を支持する石座となる部分である。環状部１０には凹部１５が設けられていてもよい。本実施形態では、上からみて環状部１０の周方向に複数の凹部１５が等間隔で設けられる。凹部１５には小宝石Ｓ２が配置され、中央の開口部１０ｈに配置される宝石Ｓ１の周りを飾ることができる。 The annular portion 10 is a portion that serves as a stone seat that supports the jewel S1 in a state where the jewel S1 is arranged in the opening 10h. The annular portion 10 may be provided with a recess 15. In the present embodiment, a plurality of recesses 15 are provided at equal intervals in the circumferential direction of the annular portion 10 when viewed from above. A small jewel S2 is arranged in the recess 15, and the jewel S1 arranged in the central opening 10h can be decorated.

環状部１０の開口部１０ｈに宝石Ｓ１を配置すると、環状部１０の開口部１０ｈ側の縁から突出する複数の支持片２０によって宝石Ｓ１の下方が支持される。宝石支持台１では、宝石Ｓ１の下方の支持を複数本の支持片２０によって行うため、宝石Ｓ１を環状部１０の開口部１０ｈ側の縁の全体で支持する必要がない。これにより、宝石Ｓ１の下方を支持する部材の面積を狭くして、その分、開口部１０ｈの面積を広くすることができる。開口部１０ｈを広くできることで、宝石Ｓ１の下方から十分な光を宝石Ｓ１へ届けることができる。また、隣り合う支持片２０の間からも光が届くため、宝石Ｓ１の側方にも十分な光を届けることができる。 When the jewel S1 is arranged in the opening 10h of the annular portion 10, the lower portion of the jewel S1 is supported by a plurality of support pieces 20 protruding from the edge of the annular portion 10 on the opening 10h side. In the jewel support base 1, since the lower support of the jewel S1 is performed by a plurality of support pieces 20, it is not necessary to support the jewel S1 by the entire edge of the annular portion 10 on the opening 10h side. As a result, the area of the member supporting the lower part of the jewel S1 can be narrowed, and the area of the opening 10h can be increased accordingly. By making the opening 10h wider, sufficient light can be delivered to the jewel S1 from below the jewel S1. Further, since the light reaches between the adjacent support pieces 20, sufficient light can be delivered to the side of the jewel S1.

本実施形態では、環状部１０に４つの支持片２０が設けられる。４つの支持片２０は、上からみて９０度間隔で配置される。これにより、宝石Ｓ１の下方を４箇所の支持片２０で支える。支持片２０の数が少ないほど開口部１０ｈの面積を広くできるが、支持強度は低下する。一方、支持片２０の数が多くなると支持強度は高まるが、開口部１０ｈの面積が狭くなる。したがって、支持片２０の数は、３つ以上８つ以下程度が好ましい。 In the present embodiment, the annular portion 10 is provided with four support pieces 20. The four support pieces 20 are arranged at intervals of 90 degrees when viewed from above. As a result, the lower part of the jewel S1 is supported by the four support pieces 20. As the number of support pieces 20 decreases, the area of the opening 10h can be increased, but the support strength decreases. On the other hand, as the number of support pieces 20 increases, the support strength increases, but the area of the opening 10h becomes narrower. Therefore, the number of support pieces 20 is preferably about 3 or more and 8 or less.

複数本の支持片２０のそれぞれは、環状部１０の開口部１０ｈ側の縁から斜め上方に延出するように設けられることが好ましい。これにより、複数本の支持片２０で宝石Ｓ１の下方を支持すると、開口部１０ｈ内で宝石Ｓ１が浮いているように支持される。 It is preferable that each of the plurality of support pieces 20 is provided so as to extend obliquely upward from the edge of the annular portion 10 on the opening 10h side. As a result, when the lower part of the jewel S1 is supported by the plurality of support pieces 20, the jewel S1 is supported so as to float in the opening 10h.

環状部１０に設けられる複数本の第１押さえ爪３１は、開口部１０ｈに配置された宝石Ｓ１の外周を押さえる。宝石支持台１では、開口部１０ｈに配置された宝石Ｓ１の下方を複数本の支持片２０で支え、宝石Ｓ１の外周を複数本の第１押さえ爪３１で押さえることで、宝石Ｓ１を確実に固定することができる。 The plurality of first pressing claws 31 provided on the annular portion 10 press the outer circumference of the jewel S1 arranged in the opening 10h. In the jewel support base 1, the lower part of the jewel S1 arranged in the opening 10h is supported by a plurality of support pieces 20, and the outer circumference of the jewel S1 is pressed by a plurality of first pressing claws 31 to ensure that the jewel S1 is pressed. Can be fixed.

複数本の第１押さえ爪３１は、開口部１０ｈの周囲に互いに等間隔で配置されることが好ましい。これにより、複数本の第１押さえ爪３１によって宝石Ｓ１をバランス良く押さえることができる。本実施形態では、４つの支持片２０のそれぞれの両側に第１押さえ爪３１が配置される。すなわち、４つの支持片２０のそれぞれに２つの第１押さえ爪３１が１つずつ両側に配置されることで合計８つの第１押さえ爪３１が設けられる。８つの第１押さえ爪３１は、上からみて等間隔（４５度の間隔）で配置される。これにより、宝石Ｓ１の確実な固定とともに、デザイン的な安定感を得ることができる。 It is preferable that the plurality of first pressing claws 31 are arranged around the opening 10h at equal intervals. As a result, the jewel S1 can be pressed in a well-balanced manner by the plurality of first pressing claws 31. In the present embodiment, the first pressing claws 31 are arranged on both sides of each of the four support pieces 20. That is, a total of eight first pressing claws 31 are provided by arranging two first pressing claws 31 on both sides of each of the four support pieces 20. The eight first pressing claws 31 are arranged at equal intervals (intervals of 45 degrees) when viewed from above. As a result, the jewel S1 can be securely fixed and a sense of stability in design can be obtained.

第１押さえ爪３１には、開口部１０ｈに配置された宝石Ｓ１の外周部分が嵌め込まれる溝部３１ａを備える。例えば、宝石Ｓ１がブリリアントカットされたダイヤモンドの場合、ガードル部分に合わせて溝部３１ａが形成される。これにより、第１押さえ爪３１の溝部３１ａがガードル部分に嵌まり、確実に宝石Ｓ１の外周を押さえて固定することができる。 The first pressing claw 31 is provided with a groove portion 31a into which the outer peripheral portion of the jewel S1 arranged in the opening 10h is fitted. For example, when the jewel S1 is a brilliant-cut diamond, a groove 31a is formed in accordance with the girdle portion. As a result, the groove portion 31a of the first pressing claw 31 fits into the girdle portion, and the outer circumference of the jewel S1 can be reliably pressed and fixed.

環状部１０に凹部１５が設けられている場合、環状部１０を上方からみて、凹部１５における開口部１０ｈとは反対側に第２押さえ爪３２が設けられる。第２押さえ爪３２は環状部１０の外周側に立設され、環状部１０の内周側に立設される第１押さえ爪３１との間で小宝石Ｓ２を押さえる役目を果たす。 When the annular portion 10 is provided with the recess 15, the second pressing claw 32 is provided on the side of the recess 15 opposite to the opening 10h when the annular portion 10 is viewed from above. The second pressing claw 32 is erected on the outer peripheral side of the annular portion 10 and serves to press the small jewel S2 between the second pressing claw 32 and the first pressing claw 31 erected on the inner peripheral side of the annular portion 10.

本実施形態では、環状部１０に８つの凹部１５が等間隔に設けられ、凹部１５のそれぞれに対応して第２押さえ爪３２が設けられる。環状部１０の上からみると、８つの第２押さえ爪３２は、８つの第１押さえ爪３１と周方向に半ピッチずれた位置となる。これにより、凹部１５に小宝石Ｓ２を配置した状態で、１つの小宝石Ｓ２を２つの第１押さえ爪３１と１つの第２押さえ爪３２との３点で押さえることができる。 In the present embodiment, eight recesses 15 are provided in the annular portion 10 at equal intervals, and a second pressing claw 32 is provided corresponding to each of the recesses 15. When viewed from above the annular portion 10, the eight second pressing claws 32 are positioned at positions offset by half a pitch in the circumferential direction from the eight first pressing claws 31. As a result, with the small jewel S2 arranged in the recess 15, one small jewel S2 can be pressed by three points, the two first pressing claws 31 and the one second pressing claw 32.

第１押さえ爪３１は、例えば図１、図３（ｂ）に示すように、凹部１５に配置された小宝石Ｓ２の外周部分が嵌め込まれる溝部３１ｂを備える。凹部１５に配置された小宝石Ｓ２の外周部分は、その凹部１５に面して設けられた２つの第１押さえ爪３１の溝部３１ｂに嵌め込まれる。例えば、小宝石Ｓ２がブリリアントカットされたダイヤモンドの場合、ガードル部分に合わせて溝部３１ｂが形成される。第１押さえ爪３１は、宝石Ｓ１の押さえとともに小宝石Ｓ２の押さえとしても用いられることから、第１押さえ爪３１の共用によって無駄なく宝石Ｓ１および小宝石Ｓ２を固定することができる。 As shown in FIGS. 1 and 3B, for example, the first pressing claw 31 includes a groove portion 31b into which the outer peripheral portion of the small jewel S2 arranged in the recess 15 is fitted. The outer peripheral portion of the small jewel S2 arranged in the recess 15 is fitted into the groove 31b of the two first pressing claws 31 provided facing the recess 15. For example, when the small gem S2 is a brilliant-cut diamond, a groove 31b is formed in accordance with the girdle portion. Since the first pressing claw 31 is used as a pressing of the small jewel S2 together with the pressing of the jewel S1, the jewel S1 and the small jewel S2 can be fixed without waste by sharing the first pressing claw 31.

また、凹部１５の中央部分には孔１５ｈが設けられる。これにより、凹部１５に配置した小宝石Ｓ２の下方から小宝石Ｓ２へ十分な光を届けることができる。 Further, a hole 15h is provided in the central portion of the recess 15. As a result, sufficient light can be delivered to the small jewel S2 from below the small jewel S2 arranged in the recess 15.

本実施形態に係る宝石支持台１に宝石Ｓ１および小宝石Ｓ２が配置されることで、装飾具１００が構成される（図４参照）。宝石支持台１を用いた装飾具１００では、宝石Ｓ１の下方の支持を複数本の支持片２０で行うため、宝石Ｓ１の下方や側方から十分な光を宝石Ｓ１に届けることができる。また、支持片２０および第１押さえ爪３１によって宝石Ｓ１を確実に固定でき、第１押さえ爪３１および第２押さえ爪３２によって小宝石Ｓ２を確実に固定しつつ、宝石Ｓ１および小宝石Ｓ２の上方のみならず、下方や側方から十分な光を届けることができる装飾具１００が実現する。 The ornament 100 is configured by arranging the jewel S1 and the small jewel S2 on the jewel support 1 according to the present embodiment (see FIG. 4). In the ornament 100 using the jewel support base 1, since the lower support of the jewel S1 is supported by the plurality of support pieces 20, sufficient light can be delivered to the jewel S1 from below or from the side of the jewel S1. Further, the jewel S1 can be securely fixed by the support piece 20 and the first pressing claw 31, and the small jewel S2 is securely fixed by the first pressing claw 31 and the second pressing claw 32, while being above the jewel S1 and the small jewel S2. Not only that, a decorative tool 100 capable of delivering sufficient light from below or from the side is realized.

図８は、装飾具を下からみた斜視図である。
本実施形態に係る宝石支持台１を用いた装飾具１００では、中央に宝石Ｓ１が配置され、その周囲に８つの小宝石Ｓ２が配置されたデザインを有する。上からみると、宝石Ｓ１および小宝石Ｓ２は８つの第１押さえ爪３１および８つの第２押さえ爪３２によってバランスよく固定される。 FIG. 7 is a plan view of the ornament.
FIG. 8 is a perspective view of the ornament as viewed from below.
The ornament 100 using the jewel support 1 according to the present embodiment has a design in which the jewel S1 is arranged in the center and eight small jewels S2 are arranged around the jewel S1. Seen from above, the jewel S1 and the small jewel S2 are fixed in a well-balanced manner by the eight first pressing claws 31 and the eight second pressing claws 32.

また、装飾具１００を下からみると、開口部１０ｈに配置された宝石Ｓ１は４つの支持片２０によって支持されるため、開口部１０ｈの中央のみならず、各支持片２０の間からも光が宝石Ｓ１へ届くようになる。小宝石Ｓ２には、凹部１５の孔１５ｈから光が届く。これにより、宝石Ｓ１および小宝石Ｓ２の支持部材による光の遮りを必要以上に生じさせず、宝石Ｓ１および小宝石Ｓ２の上方のみならず下方や側方からも十分な光を届けて宝石Ｓ１および小宝石Ｓ２の輝きを得られるようになる。 Further, when the ornament 100 is viewed from below, since the jewel S1 arranged in the opening 10h is supported by the four support pieces 20, light is emitted not only from the center of the opening 10h but also from between the support pieces 20. Will reach the jewel S1. Light reaches the small jewel S2 from the hole 15h of the recess 15. As a result, the support members of the jewel S1 and the small jewel S2 do not block the light more than necessary, and sufficient light is delivered not only from above the jewel S1 and the small jewel S2 but also from the lower side and the side of the jewel S1 and the small jewel S2. You will be able to obtain the brilliance of the small jewel S2.

（比較例）
図９は、比較例に係る宝石支持台を例示する斜視図である。
比較例に係る宝石支持台１Ｂは、中央に開口部１０ｈを有する環状部１０Ｂと、環状部１０Ｂから上方に延出し、開口部１０ｈの周囲に配置される複数本の第１押さえ爪３１Ｂと、環状部１０Ｂに設けられる複数の凹部１５Ｂと、環状部１０Ｂを上方からみて、凹部１５における開口部１０ｈとは反対側に設けられる第２押さえ爪３２Ｂと、を備える。宝石支持台１Ｂでは、開口部１０ｈに宝石Ｓ１を配置すると、宝石Ｓ１の下方を環状部１０の開口部１０ｈ側の縁の全体で支持する構成となっている。すなわち、宝石支持台１Ｂでは、本実施形態に係る宝石支持台１のような支持片２０は設けられていない。 (Comparison example)
FIG. 9 is a perspective view illustrating a jewel support stand according to a comparative example.
The jewel support base 1B according to the comparative example includes an annular portion 10B having an opening 10h in the center, a plurality of first pressing claws 31B extending upward from the annular portion 10B and arranged around the opening 10h. A plurality of recesses 15B provided in the annular portion 10B and a second pressing claw 32B provided on the side opposite to the opening 10h in the recess 15 when the annular portion 10B is viewed from above are provided. In the jewel support base 1B, when the jewel S1 is arranged in the opening 10h, the lower part of the jewel S1 is supported by the entire edge of the annular portion 10 on the opening 10h side. That is, the jewel support 1B is not provided with the support piece 20 like the jewel support 1 according to the present embodiment.

比較例に係る宝石支持台１Ｂでは、環状部１０Ｂの開口部１０ｈ側の縁の全体で宝石Ｓ１を支持するため、本実施形態に係る宝石支持台１と比べて開口部１０ｈの面積が狭くなる。これにより、比較例に係る宝石支持台１Ｂでは、本実施形態に係る宝石支持台１よりも宝石Ｓ１の下方や側方からの光の取り込み量が少なくなる。 In the jewel support 1B according to the comparative example, since the jewel S1 is supported by the entire edge of the annular portion 10B on the opening 10h side, the area of the opening 10h is smaller than that of the jewel support 1 according to the present embodiment. ..
