Description

本発明はネックレスに関する。 The present invention relates to a necklace.

一般に、ネックレスは、宝石等の装飾物を備えた装飾体、装飾体に接続された紐状部材、および紐状部材の両端同士を連結させる止め具を備えている。紐状部材には、例えば、チェーン、ワイヤ、紐、糸等がある。止め具には、例えば、引き輪、カニカン、クラスプ等がある。利用者がネックレスを首に掛けた際には、装飾体は利用者の胸元に配置され、止め具は利用者の首の後ろ側に配置される。 Generally, a necklace is provided with a decorative body provided with a decorative article such as a jewelry, a string-like member connected to the decorative body, and a stopper for connecting both ends of the string-like member. The string-like member includes, for example, a chain, a wire, a string, a thread and the like. The fasteners include, for example, a pull ring, a crab can, a clasp, and the like. When the user puts the necklace on the neck, the decoration is placed on the user's chest and the stop is placed behind the user's neck.

このような一般のネックレスには次のような問題がある。すなわち、ネックレスを首に掛け、または首から外す際には、首の後ろ側の見えない位置で止め具を操作して紐状部材の両端同士を連結、または分離させる必要がある。そのため、ネックレスの掛け外しが難しいという問題がある。また、ネックレスを首に掛けている間、装飾があまり施されていない止め具がその自重により首の後ろ側から胸元の方へ移動してしまうことがある。そのため、ネックレスによる装飾効果が低下してしまうという問題がある。 Such common necklaces have the following problems. That is, when the necklace is put on or taken off from the neck, it is necessary to operate the fastener at an invisible position on the rear side of the neck to connect or separate both ends of the string member. Therefore, there is a problem that it is difficult to attach and detach the necklace. Also, while the necklace is hanging around the neck, the poorly decorated fastener may move from behind the neck to the chest due to its own weight. Therefore, there is a problem that the decoration effect by a necklace will fall.

下記の特許文献１および２には、装飾体に止め具としての機能（紐状部材の両端同士を連結させる機能）を持たせたネックレスがそれぞれ記載されている。特許文献１に記載されたネックレスは、装飾体が２つの装飾片に分割され、一方の装飾片には、押圧つまみを有する掛け金が設けられ、他方の装飾片には、導入部を有する止め金が設けられ、掛け金を止め金に係合することにより両装飾片が連結する構成を備えている。特許文献２に記載されたネックレスは、第１の部材および第２の部材からなる装飾用部材を有し、第１の部材が、一部が非連続となり得る環状部材であり、第２の部材が、側面に第１の部材を通し得る空洞を有しており、第１の部材の一部を第２の部材の空洞に通すことにより両部材が連結する構成を備えている。これらのネックレスによれば、上述した問題を解決することができると考えられる。 Patent Documents 1 and 2 below each disclose a necklace in which the decorative body has a function as a stopper (function to connect both ends of the string-like member). In the necklace described in Patent Document 1, the decorative body is divided into two decorative pieces, one decorative piece is provided with a latch having a pressing knob, and the other decorative piece is a clasp having an introduction portion. The two decorative pieces are connected by engaging the latch with the latch. The necklace described in Patent Document 2 has a decorative member consisting of a first member and a second member, and the first member is an annular member which may be partially discontinuous, and the second member Has a cavity through which the first member can pass, and has a configuration in which the two members are connected by passing a portion of the first member through the cavity of the second member. According to these necklaces, it is thought that the problem mentioned above can be solved.

しかしながら、上記特許文献１または２に記載されたネックレスには、装飾体に止め具としての機能を持たせつつ、装飾体を小さくし、かつ装飾体のデザイン性を高めることが困難であるという新たな問題がある。 However, in the necklace described in Patent Document 1 or 2, it is difficult to reduce the size of the decorative body and to enhance the design of the decorative body while giving the decorative body a function as a stopper. There is a problem.

例えば、ネックレスの装飾体のデザインとして、径寸法がおよそ３〜４ｍｍ以下の小さい宝石等の装飾物を、この装飾物よりも僅かに大きい径寸法を有する台座の正面中央に留めるといったデザインを採用した場合、装飾体の全体的な大きさが非常に小さくなる。このような非常に小さな装飾体を２つ装飾片に分割し、一方の装飾片に特許文献１に記載されたような掛け金を設け、他方の装飾片に特許文献１に記載されたような止め金を設けると、装飾体のデザイン性が低下してしまう。具体的には、掛け金や止め金が台座から径方向外側にはみ出し、装飾体を正面から見た場合に、掛け金や止め金の一部が露出してしまい、その結果、装飾体のデザインが崩れてしまう。また、掛け金や止め金が台座からはみ出さないように、これらを小さくした場合には、押圧つまみを押して掛け金を止め金から外す操作が困難になってしまう。 For example, as a design of the decoration of the necklace, a design is adopted in which a small jewelry or other small jewelry with a diameter of approximately 3 to 4 mm is fixed at the front center of a pedestal having a diameter slightly larger than the decoration. If so, the overall size of the decor is very small. Such a very small decorative body is divided into two decorative pieces, and one decorative piece is provided with a latch as described in Patent Document 1 and the other decorative piece is as described in Patent Document 1 The provision of gold reduces the design of the decorative body. Specifically, when the latch and the lock protrude radially outward from the base and the decoration is viewed from the front, a part of the latch and the lock is exposed, and as a result, the design of the decoration is broken. It will In addition, when these are made smaller so that the latch and the lock do not protrude from the pedestal, the operation of pressing the pressing knob to remove the latch from the lock becomes difficult.

また、ネックレスの装飾体のデザインとして上述したようなデザインを採用した場合、そのようなデザインを維持しつつ、特許文献２に記載されているように装飾体を第１の部材と第２の部材とに分割し、第１の部材をその一部が非連続となり得る環状の形状とし、第２の部材をその側面に第１の部材を通し得る空洞を有する形状とすることは困難である。 In addition, when the design as described above is adopted as the design of the decoration of the necklace, while maintaining such a design, the decoration is a first member and a second member as described in Patent Document 2. It is difficult to divide the first member into an annular shape, a part of which may be discontinuous, and to form the second member into a cavity having a side through which the first member can pass.

本発明は例えば上述したような問題に鑑みなされたものであり、本発明の課題は、装飾体に止め具としての機能を持たせつつ、装飾体を小さくすることができ、かつ装飾体のデザイン性を高めることができるネックレスを提供することにある。 The present invention has been made in view of, for example, the problems as described above, and it is an object of the present invention to make a decorative body smaller while providing the decorative body with a function as a stopper, and to design the decorative body It is in providing the necklace which can raise sex.

また、図１０に示すように、筒状部材２２の周壁部の径方向の厚さｄ３は例えばおよそ０．５〜２ｍｍである。また、筒状部材２２の内径ｄ４は、石座１２の後端側部分の直径ｄ１（図７参照）と略等しい。厳密には、筒状部材２２の内径ｄ４は、石座１２の後端部分の直径ｄ１よりも、石座１２の後端側部分を筒状部材２２の内側に挿抜可能に嵌め合わせることができる程度に極僅かに大きい値に設定されている。また、筒状部材２２の外径ｄ５は、筒状部材２２の内径ｄ４に筒状部材２２の周壁部の厚さｄ３の２倍の値を加えた値となる。例えば、筒状部材２２の内径ｄ４が３．８ｍｍであり、筒状部材２２の周壁部の厚さｄ３が０．６ｍｍである場合、筒状部材２２の外径ｄ５は５ｍｍとなる。 Also, as shown in FIG. 10, the radial thickness d3 of the peripheral wall portion of the cylindrical member 22 is, for example, about 0.5 to 2 mm. Further, the inner diameter d4 of the cylindrical member 22 is substantially equal to the diameter d1 (see FIG. 7) of the rear end side portion of the stone seat 12. Strictly speaking, the inner diameter d4 of the cylindrical member 22 can be fitted so as to be insertable into and removable from the rear end side portion of the stone seat 12 inside the cylindrical member 22 than the diameter d1 of the rear end portion of the stone seat 12 The value is set to a slightly larger value. The outer diameter d5 of the cylindrical member 22 is a value obtained by adding a value twice the thickness d3 of the peripheral wall of the cylindrical member 22 to the inner diameter d4 of the cylindrical member 22. For example, when the inner diameter d4 of the cylindrical member 22 is 3.8 mm and the thickness d3 of the peripheral wall of the cylindrical member 22 is 0.6 mm, the outer diameter d5 of the cylindrical member 22 is 5 mm.

また、図１２において筒状部材２２の右側の周壁部には留め穴２４が形成されている。留め穴２４は、石座１２が筒状部材２２の内側に挿入された際に、第１の装飾片１１のチェーン接続部１４の基部１４Ｂを通すことにより石座１２を筒状部材２２の内側から外れないようにするための穴である。留め穴２４は、筒状部材２２の周壁部を貫通しており、筒状部材２２の周方向に所定の長さ伸長している。また、留め穴２４の上端部２４Ａの位置は、第１の装飾片１１と第２の装飾片２１との連結が完了した状態（図３に示す状態）における第１の装飾片１１のチェーン接続部１４の基部１４Ｂの位置と一致するように設定されている。 Further, in FIG. 12, a retaining hole 24 is formed in the peripheral wall on the right side of the cylindrical member 22. The fastening hole 24 passes through the base 14 B of the chain connection portion 14 of the first decorative piece 11 when the stone seat 12 is inserted into the inside of the tubular member 22, so that the stone seat 12 can be inserted into the inside of the tubular member 22. It is a hole to keep it from coming off. The fastening hole 24 penetrates the peripheral wall portion of the cylindrical member 22 and extends in the circumferential direction of the cylindrical member 22 by a predetermined length.

It is set to coincide with the position of the base 14B of the portion 14.

また、図１０において筒状部材２２の右側の周壁部には切り欠き２５が形成されている。具体的には、切り欠き２５は、図１１に示すように、筒状部材２２の周壁部において筒状部材２２の前端側の端面から留め穴２４の下端部２４Ｂに至る部分に形成されている。切り欠き２５は、第１の装飾片１１のチェーン接続部１４の基部１４Ｂを留め穴２４内に対して挿抜するための通路として機能する。 Further, in FIG. 10, a notch 25 is formed in the peripheral wall portion on the right side of the cylindrical member 22. Specifically, as shown in FIG. 11, the notch 25 is formed in the peripheral wall portion of the cylindrical member 22 from the end face on the front end side of the cylindrical member 22 to the lower end 24 B of the fastening hole 24. . The notch 25 functions as a passage for inserting and removing the base 14 B of the chain connection portion 14 of the first decorative piece 11 into the fastening hole 24.

また、図１０において筒状部材２２の左上側部分にはチェーン接続部２３が設けられている。チェーン接続部２３は、筒状部材２２の外周面の左上側部分から筒状部材２２の径方向外側へ突出している。チェーン接続部２３は具体的には環であり、第１の装飾片１１のチェーン接続部１４の環１４Ａと同じ形状を有している。チェーン接続部２３は筒状部材２２の外周面に直接固定されている。 Further, in FIG. 10, a chain connection portion 23 is provided on the upper left side portion of the cylindrical member 22. The chain connection portion 23 protrudes outward in the radial direction of the cylindrical member 22 from the upper left side portion of the outer peripheral surface of the cylindrical member 22. The chain connection portion 23 is specifically a ring, and has the same shape as the ring 14 A of the chain connection portion 14 of the first decorative piece 11. The chain connection portion 23 is directly fixed to the outer peripheral surface of the cylindrical member 22.

（係止機構）
また、装飾体２は、筒状部材２２の内側に挿入された石座１２を筒状部材２２に係止することにより石座１２の筒状部材２２に対する移動を規制する係止機構３１を備えている。係止機構３１は、第１の装飾片１１のチェーン接続部１４の基部１４Ｂと筒状部材２２の切り欠き２５とが互いに対応しない位置に石座１２が止まるように石座１２を係止する機能、および第１の装飾片１１のチェーン接続部１４の基部１４Ｂと筒状部材２２の切り欠き２５とが互いに対応する位置に石座１２が止まるように石座１２を係止する機能を有している。 (Locking mechanism)
Further, the decorative body 2 is provided with a locking mechanism 31 for restricting the movement of the stone seat 12 relative to the cylindrical member 22 by locking the stone seat 12 inserted inside the cylindrical member 22 to the cylindrical member 22. ing. The locking mechanism 31 locks the stone seat 12 so that the stone seat 12 stops at a position where the base 14B of the chain connection portion 14 of the first decorative piece 11 and the notch 25 of the cylindrical member 22 do not correspond to each other. Has a function and a function to lock the stone seat 12 so that the stone seat 12 is stopped at a position where the base 14B of the chain connection portion 14 of the first decorative piece 11 and the notch 25 of the cylindrical member 22 correspond to each other doing.

係止機構３１は、図５に示すように、第１の装飾片１１の石座１２内に形成された収容穴３２、凸状係止部３３、ばね３４および栓３５、並びに第２の装飾片２１の筒状部材２２に形成された２つの凹状係止部（第１の凹状係止部３６および第２の凹状係止部３７）を備えている。 The locking mechanism 31 is, as shown in FIG. 5, a receiving hole 32 formed in the stone seat 12 of the first decorative piece 11, a convex locking portion 33, a spring 34 and a plug 35, and a second decoration Two concave locking portions (a first concave locking portion 36 and a second concave locking portion 37) formed on the cylindrical member 22 of the piece 21 are provided.

図８または図９に示すように、収容穴３２は、石座１２の後端側部分に形成され、石座１２の軸線と直交する方向に伸長しており、石座１２を貫通している。また、本実施形態の収容穴３２は、石座１２を正面から見た場合に、石座１２の中央を基準として、チェーン接続部１４が設けられている部分の反対側に形成されている。具体的には、収容穴３２は、図８において石座１２の下側部分に形成されている。 As shown in FIG. 8 or FIG. 9, the accommodation hole 32 is formed in the rear end side portion of the stone seat 12, extends in a direction orthogonal to the axis of the stone seat 12, and penetrates the stone seat 12. . Moreover, the accommodation hole 32 of this embodiment is formed in the other side of the part in which the chain connection part 14 is provided on the basis of the center of the stone seat 12, when the stone seat 12 is seen from the front. Specifically, the accommodation hole 32 is formed in the lower portion of the stone seat 12 in FIG.

凸状係止部３３は例えば金属または樹脂製の球体である。ばね３４は例えばつる巻きばねである。栓３５は金属または樹脂により形成されている。凸状係止部３３およびばね３４は収容穴３２内に収容されている。 The convex locking portion 33 is, for example, a sphere made of metal or resin. The spring 34 is, for example, a helical spring. The plug 35 is formed of metal or resin. The convex locking portion 33 and the spring 34 are housed in the housing hole 32.

図８において、収容穴３２の直径は、その一端部（下側端部）を除き、凸状係止部３３およびばね３４のいずれの直径よりも大きい値に設定されている。一方、収容穴３２の一端部の直径は、凸状係止部３３の直径よりも僅かに小さい値に設定されている。装飾体２の製造時に、収容穴３２の他端部（右側端部）から、収容穴３２内へ凸状係止部３３およびばね３４が順次挿入され、その後、収容穴３２の他端部に栓３５が挿入され、固定される。収容穴３２の他端部に栓３５が固定された状態では、ばね３４は栓３５と凸状係止部３３との間で弾性変形して縮小し、凸状係止部３３を収容穴３２の一端部に向けて押している。収容穴３２の一端部の直径は凸状係止部３３の直径よりも小さいので凸状係止部３３は収容穴３２の一端部から収容穴３２の外へ脱落することはない。しかしながら、収容穴３２の一端部の直径と凸状係止部３３の直径との差は僅かなので、凸状係止部３３の一部が収容穴３２の一端部から外へ突出している。 In FIG. 8, the diameter of the accommodation hole 32 is set to a value larger than any of the diameters of the convex locking portion 33 and the spring 34 except for one end (lower end) thereof. On the other hand, the diameter of one end of the accommodation hole 32 is set to a value slightly smaller than the diameter of the convex locking portion 33. At the time of manufacturing the decorative body 2, the convex locking portion 33 and the spring 34 are sequentially inserted into the accommodation hole 32 from the other end (right end) of the accommodation hole 32, and then to the other end of the accommodation hole 32. The plug 35 is inserted and fixed. In a state where the plug 35 is fixed to the other end of the accommodation hole 32, the spring 34 is elastically deformed and contracted between the plug 35 and the convex engagement part 33, and the convex engagement part 33 is accommodated in the accommodation hole 32. Pushing towards one end of the. Since the diameter of one end of the housing hole 32 is smaller than the diameter of the convex locking portion 33, the convex locking portion 33 does not drop out of the housing hole 32 from the one end of the housing hole 32. However, since the difference between the diameter of one end of the housing hole 32 and the diameter of the convex locking portion 33 is small, a part of the convex locking portion 33 protrudes from one end of the housing hole 32 to the outside.

凸状係止部３３において収容穴３２の一端部から外へ突出した部分に、この突出方向に対して逆向きの外力が加わると、ばね３４が弾性変形してさらに縮小し、凸状係止部３３が収容穴３２内に入り込み、凸状係止部３３の全体が収容穴３２内に埋没した状態となる。一方、当該外力が加わらなくなると、ばね３４の付勢力により凸状係止部３３の一部が再び収容穴３２の一端部から収容穴３２の外へ突出する。 When an external force reverse to the projecting direction is applied to a portion of the convex locking portion 33 which protrudes outward from one end of the accommodation hole 32, the spring 34 is elastically deformed and further reduced, and the convex locking is performed. The portion 33 enters the accommodation hole 32, and the entire convex locking portion 33 is buried in the accommodation hole 32. On the other hand, when the external force is not applied, a part of the convex locking portion 33 again protrudes from the one end of the accommodation hole 32 to the outside of the accommodation hole 32 by the biasing force of the spring 34.

また、図１２または図１３に示すように、第１の凹状係止部３６および第２の凹状係止部３７は筒状部材２２の周壁部の内周面にそれぞれ形成されている。第１の凹状係止部３６は、筒状部材２２の周壁部の内周面において、第１の装飾片１１のチェーン接続部１４の基部１４Ｂが留め穴２４の上端部２４Ａに位置しているときに収容穴３２の一端部と対向する位置に形成されている。本実施形態では、第１の凹状係止部３６は、筒状部材２２の周壁部の内周面における左下側部分に形成されている。また、第２の凹状係止部３７は、筒状部材２２の周壁部の内周面において、第１の装飾片１１のチェーン接続部１４の基部１４Ｂが留め穴２４の下端部２４Ｂに位置しているときに収容穴３２の一端部と対向する位置に形成されている。本実施形態では、第２の凹状係止部３７は、筒状部材２２の周壁部の内周面における左上側部分に形成されている。第１の凹状係止部３６および第２の凹状係止部３７はそれぞれ、凸状係止部３３において収容穴３２の一端部から突出した部分が嵌合するように丸く窪んだ形状を有している。 Further, as shown in FIG. 12 or FIG. 13, the first concave locking portion 36 and the second concave locking portion 37 are respectively formed on the inner peripheral surface of the peripheral wall portion of the cylindrical member 22. The base 14 B of the chain connection portion 14 of the first decorative piece 11 is positioned at the upper end 24 A of the fastening hole 24 on the inner peripheral surface of the peripheral wall of the cylindrical member 22 in the first concave locking portion 36. It is formed at a position opposite to one end of the accommodation hole 32. In the present embodiment, the first concave locking portion 36 is formed on the lower left side portion of the inner peripheral surface of the peripheral wall portion of the cylindrical member 22. Further, the base 14 B of the chain connection portion 14 of the first decorative piece 11 is positioned at the lower end portion 24 B of the fastening hole 24 on the inner peripheral surface of the peripheral wall portion of the cylindrical member 22. It is formed in the position which opposes the one end part of the accommodation hole 32 when. In the present embodiment, the second concave locking portion 37 is formed on the upper left side portion of the inner peripheral surface of the peripheral wall portion of the cylindrical member 22. Each of the first concave locking portion 36 and the second concave locking portion 37 has a concaved shape so that the portion protruding from the one end of the accommodation hole 32 in the convex locking portion 33 is fitted. ing.

（装飾片の連結・分離）
図１４は、ネックレス１において、第１の装飾片１１と第２の装飾片２１とを連結させる方法を示している。 (Connection and separation of decorative pieces)
FIG. 14 shows a method of connecting the first decorative piece 11 and the second decorative piece 21 in the necklace 1.

ネックレス１を首に掛ける際には、第１の装飾片１１と第２の装飾片２１とを連結させる。これにより、チェーン３の両端同士が連結される。第１の装飾片１１と第２の装飾片２１とを連結させる方法は次の通りである。 When hanging the necklace 1 on the neck, the first decorative piece 11 and the second decorative piece 21 are connected. Thereby, both ends of the chain 3 are connected. The method of connecting the first decorative piece 11 and the second decorative piece 21 is as follows.

まず、利用者は、図１４（１）に示すように、第１の装飾片１１の石座１２と第２の装飾片２１の筒状部材２２とを両者の軸線が一致するように前後に位置させる。次に、利用者は、石座１２に固定されたチェーン接続部１４の基部１４Ｂと筒状部材２２に形成された切り欠き２５とが互いに対応する位置となるように、石座１２または筒状部材２２の周方向の位置を調節する。次に、利用者は、チェーン接続部１４の基部１４Ｂを切り欠き２５に通しつつ、石座１２の後端側部分を筒状部材２２の内側に挿入する。 First, as shown in FIG. 14 (1), the user moves the stone seat 12 of the first decorative piece 11 and the cylindrical member 22 of the second decorative piece 21 back and forth so that the axes of the two coincide. Position. Next, the user places the stone seat 12 or the tubular shape so that the base 14B of the chain connection portion 14 fixed to the stone seat 12 and the notches 25 formed in the tubular member 22 correspond to each other. The circumferential position of the member 22 is adjusted. Next, the user inserts the rear end side portion of the stone seat 12 into the inside of the cylindrical member 22 while passing the base 14 B of the chain connection portion 14 through the notch 25.

石座１２の後端側部分が筒状部材２２の内側へ挿入され、石座１２の鍔部１７の後端面が筒状部材２２の前端面に接触すると、図１４（２）に示すように、チェーン接続部１４の基部１４Ｂが切り欠き２５を通り抜け、筒状部材２２に形成された留め穴２４内に入る。このとき、図１４（３）および（４）に示すように、チェーン接続部１４の基部１４Ｂは、切り欠き２５と対応する位置、具体的には、留め穴２４の下端部２４Ｂに位置する。その結果、石座１２に形成された収容穴３２の一端部が、筒状部材２２に形成された第２の凹状係止部３７と対向する。したがって、凸状係止部３３の一部が第２の凹状係止部３７内に入り、両者が係合する。この係合により、石座１２が筒状部材２２に係止され、石座１２の筒状部材２２に対する移動が規制される。具体的には、筒状部材２２の内側に挿入された石座１２が筒状部材２２から滑り落ちることが防止される。もっとも、凸状係止部３３と第２の凹状係止部３７との係合による係止力は、石座１２がその自重により筒状部材２２から勝手に滑り落ちることを防止できる程度の弱い係止力である。利用者は石座１２に手で力を加えることにより、石座１２を筒状部材２２に対して容易に移動させることができる。 When the rear end side portion of the stone seat 12 is inserted into the inside of the cylindrical member 22 and the rear end face of the flange portion 17 of the stone seat 12 contacts the front end face of the cylindrical member 22, as shown in FIG. The base portion 14B of the chain connection portion 14 passes through the notch 25 and enters the retaining hole 24 formed in the cylindrical member 22. At this time, as shown in FIGS. 14 (3) and (4), the base 14B of the chain connection portion 14 is located at a position corresponding to the notch 25, specifically, the lower end 24B of the fastening hole 24. As a result, one end portion of the accommodation hole 32 formed in the stone seat 12 faces the second concave locking portion 37 formed in the cylindrical member 22. Therefore, a part of the convex locking portion 33 enters the second concave locking portion 37, and both are engaged. By this engagement, the stone seat 12 is locked to the cylindrical member 22 and the movement of the stone seat 12 relative to the cylindrical member 22 is restricted. Specifically, the stone seat 12 inserted inside the cylindrical member 22 is prevented from sliding off the cylindrical member 22. However, the locking force due to the engagement between the convex locking portion 33 and the second concave locking portion 37 is a weak engagement that can prevent the stone seat 12 from sliding off the tubular member 22 by its own weight. It is a stopping power. The user can easily move the stone seat 12 relative to the tubular member 22 by manually applying a force to the stone seat 12.

次に、利用者は、筒状部材２２の内側に挿入された石座１２を筒状部材２２に対して、所定方向（図１４（３）中の反時計回り方向）に回転させる。これにより、凸状係止部３３が第２の凹状係止部３７の縁に押されて収容穴３２内に没入し、チェーン接続部１４の基部１４Ｂが留め穴２４内を反時計回り方向に移動する。そして、チェーン接続部１４の基部１４Ｂは、切り欠き２５と対応しない位置、具体的には、留め穴２４の上端部２４Ａに到達する。その結果、チェーン接続部１４の基部１４Ｂが留め穴２４内において前後方向（筒状部材２２の軸方向）に略移動不能な状態となり、それゆえ、石座１２が筒状部材２２に対して前後方向に略移動不能な状態となる。したがって、石座１２が筒状部材２２の内側から外れなくなり、図３および図４に示すように、第１の装飾片１１と第２の装飾片２１とが互いに連結される。 Next, the user rotates the stone seat 12 inserted inside the cylindrical member 22 with respect to the cylindrical member 22 in a predetermined direction (counterclockwise direction in FIG. 14 (3)). As a result, the convex locking portion 33 is pushed by the edge of the second concave locking portion 37 and is sunk into the accommodation hole 32, and the base 14B of the chain connection portion 14 in the locking hole 24 in the counterclockwise direction. Moving. Then, the base 14 B of the chain connection portion 14 reaches a position not corresponding to the notch 25, specifically, the upper end 24 A of the fastening hole 24. As a result, the base portion 14B of the chain connection portion 14 is substantially immovable in the holding hole 24 in the front-rear direction (the axial direction of the cylindrical member 22). It becomes almost impossible to move in the direction. Therefore, the stone seat 12 does not come off from the inside of the cylindrical member 22, and as shown in FIGS. 3 and 4, the first decorative piece 11 and the second decorative piece 21 are connected to each other.

チェーン接続部１４の基部１４Ｂが留め穴２４の上端部２４Ａに到達したとき、図５に示すように、石座１２に形成された収容穴３２の一端部が、筒状部材２２に形成された第１の凹状係止部３６と対向する。したがって、凸状係止部３３の一部が第１の凹状係止部３６内に入り、両者が係合する。この係合により、石座１２が筒状部材２２に係止され、石座１２の筒状部材２２に対する移動が規制される。具体的には、装飾体２に加わる振動等により、石座１２が筒状部材２２に対して上記所定方向とは逆の方向（時計回り方向）に勝手に回転することが防止される。もっとも、凸状係止部３３と第１の凹状係止部３６との係合による係止力は、装飾体に加わった振動等により石座１２が筒状部材２２に対して勝手に回転することを防止できる程度の弱い係止力である。利用者は石座１２に手で力を加えることにより、石座１２を筒状部材２２に対して時計回り方向に容易に回転させることができる。 When the base portion 14B of the chain connection portion 14 reaches the upper end portion 24A of the fastening hole 24, one end portion of the accommodation hole 32 formed in the stone seat 12 is formed in the cylindrical member 22 as shown in FIG. It faces the first concave locking portion 36. Therefore, a part of the convex locking portion 33 enters the first concave locking portion 36, and both are engaged. By this engagement, the stone seat 12 is locked to the cylindrical member 22 and the movement of the stone seat 12 relative to the cylindrical member 22 is restricted. Specifically, the vibration or the like applied to the decorative body 2 prevents the stone seat 12 from freely rotating in the direction (clockwise direction) opposite to the predetermined direction with respect to the cylindrical member 22. However, the locking force due to the engagement between the convex locking portion 33 and the first concave locking portion 36 causes the stone seat 12 to rotate freely with respect to the cylindrical member 22 due to the vibration or the like applied to the decoration. It is a weak locking force that can prevent that. The user can easily rotate the stone seat 12 clockwise with respect to the tubular member 22 by manually applying a force to the stone seat 12.

ネックレス１を首から外す際には、第１の装飾片１１と第２の装飾片２１とを分離させる。これにより、チェーン３の両端が分離する。第１の装飾片１１と第２の装飾片２１とを分離させる方法は次の通りである。 When removing the necklace 1 from the neck, the first decorative piece 11 and the second decorative piece 21 are separated. Thereby, both ends of the chain 3 are separated. The method for separating the first decorative piece 11 and the second decorative piece 21 is as follows.

まず、利用者は、筒状部材２２の内側にある石座１２を筒状部材２２に対して上記所定方向とは逆の方向（時計回り方向）に回転させる。これにより、凸状係止部３３が第１の凹状係止部３６の縁に押されて収容穴３２内に没入し、チェーン接続部１４の基部１４Ｂが留め穴２４内を時計回り方向に移動する。そして、チェーン接続部１４の基部１４Ｂは、切り欠き２５と対応する位置、具体的には、留め穴２４の下端部２４Ｂに到達する。その結果、チェーン接続部１４の基部１４Ｂが切り欠き２５を介して留め穴２４から出ることが可能になり、石座１２が筒状部材２２に対して前後方向に移動できるようになる。次に、利用者は、石座１２を筒状部材２２から外し、第１の装飾片１１と第２の装飾片２１とを分離させる。 First, the user rotates the stone seat 12 inside the cylindrical member 22 with respect to the cylindrical member 22 in the direction (clockwise direction) opposite to the predetermined direction. As a result, the convex locking portion 33 is pushed by the edge of the first concave locking portion 36 and sinks into the housing hole 32, and the base 14B of the chain connection portion 14 moves in the locking hole 24 in the clockwise direction. Do. Then, the base 14 B of the chain connection portion 14 reaches a position corresponding to the notch 25, specifically, the lower end 24 B of the fastening hole 24. As a result, the base 14 B of the chain connection portion 14 can exit from the holding hole 24 through the notch 25, and the stone seat 12 can move in the front-rear direction with respect to the cylindrical member 22. Next, the user removes the stone seat 12 from the cylindrical member 22 and separates the first decorative piece 11 and the second decorative piece 21.
