Description

本発明は、開閉によりリングサイズを調節しつつ指の外方より円滑かつ強固に装着でき、かつ取外しも容易な開閉指輪の止着固定構造とその指輪の製造方法に関する。   The present invention relates to a fastening and fixing structure for an opening and closing ring that can be smoothly and firmly attached to the outside of a finger while adjusting the ring size by opening and closing and that can be easily removed, and a method for manufacturing the ring.

従来、環状の指輪を二つに分割し、分割した半片同士を回動可能に軸着して開閉し、指の外方よりリングサイズを調整しつつ着脱するようにした開閉指輪が知られている。この種の指輪として、例えば、本件出願人は、特許文献１の指輪を出願している。   Conventionally, an open / close ring is known in which an annular ring is divided into two parts, and the divided halves are pivotally attached to each other so as to be opened and closed, and the ring size is adjusted from the outside of the finger to be attached and detached. Yes. As this type of ring, for example, the present applicant has applied for the ring of Patent Document 1.

同文献１の指輪は、一対のリング部材の基部の二又部と装入基部との間に金属薄板が介在され、軸着部で加締められて一対のリング部材が軸着部を介して回動自在に設けられている。金属薄板の一面には、膨出されて軸穴を有するアール面が形成され、この一対のアール面同士が当接されて金属薄板同士に負荷が与えられ、二又部と装入基部との圧接面に金属薄板の外縁部が圧接面から突出しない状態で圧接されている。   In the ring of the literature 1, a thin metal plate is interposed between a bifurcated portion of a base portion of a pair of ring members and a charging base portion, and the pair of ring members are interposed via the shaft-attached portions. It is provided rotatably. On one surface of the thin metal plate, a rounded surface having a shaft hole is formed, the pair of rounded surfaces are brought into contact with each other, a load is applied to the thin metal plate, and the bifurcated portion and the charging base portion The outer edge of the metal thin plate is pressed against the pressure contact surface without protruding from the pressure contact surface.

これによると、二又部と装入基部との間に介在させた金属薄板でリング部材同士に強い保持力を発揮させながら、金属薄板の外縁部の外部への突出を防止して装飾性を高めている。装着時には、アール面同士の当接により負荷を与えつつリング部材同士を開閉し、指の太さに合わせてサイズを調整しながらワンタッチで装着でき、装着後には、アール面同士の強い保持力によりリング部材同士の回転を防止して指からの脱落を確実に防止できるようになっている。金属薄板で所定のリングサイズを維持できるため、指が圧迫されることも防いでいる。   According to this, the metal thin plate interposed between the bifurcated portion and the charging base portion exerts a strong holding force between the ring members, while preventing the outer edge portion of the metal thin plate from protruding to the outside. It is increasing. At the time of wearing, the ring members can be opened and closed while applying load by contact between the rounded surfaces, and can be worn with one touch while adjusting the size according to the thickness of the finger. After wearing, due to the strong holding force between the rounded surfaces The ring members can be prevented from rotating to prevent the finger from falling off. Since a predetermined ring size can be maintained with a thin metal plate, the finger is also prevented from being pressed.

しかしながら、特許文献１の指輪においては、金属薄板の一面を膨出させたアール面同士を当接させて負荷を発生させているため、リング部材の開状態から閉状態までの装着動作の間で一定の強い力が発生し続けることになる。これにより、指への装着時には、この負荷に対してリング部材同士を大きい力で閉じる方向に回転する必要がある。そのため、装着作業が難しくなることがあり、指の太さに合わせたリング部材同士の回転の微調整も困難になる場合がある。一方、指から取外す際にも、一定の強い負荷に対して強い力でリング部材同士を広げる必要があり、片手では操作にくくなる場合もある。
この指輪では、一対の金属薄板に形成したバリ部同士の当接によって金属薄板に負荷を与えていることで、バリ部が消耗したときには、負荷の大きさが変わったり装着を維持するための負荷が不足して、リング部材が自然に緩んだり着脱作業が難しくなるおそれもある。 However, in the ring of Patent Document 1, since a load is generated by contacting the rounded surfaces of the metal thin plates that are bulged, during the mounting operation from the open state to the closed state of the ring member. A certain strong force will continue to be generated. Thereby, when mounting on a finger, it is necessary to rotate the ring members in a closing direction with a large force against the load. Therefore, the mounting operation may be difficult, and fine adjustment of the rotation of the ring members according to the thickness of the finger may be difficult. On the other hand, when removing from the finger, it is necessary to spread the ring members with a strong force against a certain strong load, and it may be difficult to operate with one hand.
In this ring, since the load is applied to the metal thin plate by contact between the burr portions formed on the pair of metal thin plates, when the burr portion is consumed, the load is changed or the load for maintaining the wearing is maintained. , There is a risk that the ring member will loosen naturally and it will be difficult to attach and detach.

本発明は、上記の課題点を解決するために開発したものであり、その目的とするところは、装身具としての装飾性を損なうことなく、リングサイズを合わせながら指の外方から円滑に着脱でき、開閉操作時には軽い力で開閉して指の太さに合わせて微調整も可能になり、装着後には保持力を向上して装着状態を強固に維持できる開閉指輪の止着固定構造とその指輪の製造方法を提供することにある。   The present invention has been developed to solve the above-mentioned problems, and the object of the present invention is to allow smooth attachment / detachment from the outside of the finger while adjusting the ring size without impairing the decorativeness of the accessory. Opening and closing operation with a light force and fine adjustment according to the thickness of the finger is possible, and after installation, the holding and fixing structure of the opening and closing ring and its ring that can maintain the wearing state firmly by improving the holding power It is in providing the manufacturing method of.

上記目的を達成するため、請求項１に係る発明は、一対の半環状のリング部材の基部を軸着部を介して軸着して円形、楕円形又は角形の指輪本体を構成し、一方のリング部材の基部に形成した二又部の間に他方のリング部材の基部に形成した装入基部を装入し、かつ前記二又部と装入基部との間に一対の金属薄板をそれぞれ介在させて軸着部の軸着ピンを加締めて一対のリング部材を回動自在に設けた開閉指輪の製造方法であって、前記金属薄板に、前記軸着部の軸穴を形成する際に、軸着方向に変形膨出された状態の変形膨出面を形成し、前記一対の金属薄板の変形膨出面同士の膨出側の当接部位を当接させて金属薄板同士に負荷を与え、前記二又部と前記装入基部に設けられた圧接面に対して、前記金属薄板の外縁部が前記圧接面から突設しない状態で金属薄板を圧接させると共に、指輪本体を閉じた状態で軸着ピンを加締めることで、前記変形膨出面同士の当接部位の圧接力を高めて指輪本体の閉じた状態を維持できるようにした開閉指輪の製造方法である。
In order to achieve the above-mentioned object, the invention according to claim 1 is configured such that a base body of a pair of semi-annular ring members is pivotally attached via a pivotal attachment part to form a circular, elliptical, or rectangular ring body. A charging base formed at the base of the other ring member is inserted between the two forks formed at the base of the ring member, and a pair of thin metal plates are interposed between the two forks and the charging base. A method of manufacturing an opening and closing ring in which a pair of ring members are rotatably provided by caulking a shaft mounting pin of a shaft mounting portion, wherein the shaft hole of the shaft mounting portion is formed in the metal thin plate Forming a deformed bulge surface in a state of being deformed and bulged in the axial direction, applying a load to the metal thin plates by contacting the bulging side contact portions between the deformed bulge surfaces of the pair of metal thin plates, The outer edge of the thin metal plate protrudes from the pressure contact surface with respect to the pressure contact surface provided on the bifurcated portion and the charging base. In this state, the metal thin plate is brought into pressure contact, and the ring main body is closed, and the shaft attachment pin is crimped to increase the pressure contact force between the contact portions of the deformed bulging surfaces, thereby maintaining the closed state of the ring main body. This is a method for manufacturing an open / close ring .

請求項２に係る発明は、二又部と装入基部の各圧接面に摩擦面を設けた開閉指輪の製造方法である。
The invention according to claim 2 is a method of manufacturing an opening and closing ring in which a friction surface is provided on each pressure contact surface of the bifurcated portion and the charging base portion.

請求項１に係る発明によると、二又部と装入基部との間に一対の金属薄板を設けていることにより、金属薄板の外部への突出を防いで装身具としての装飾性を維持しつつ、この一対の金属薄板でリング部材同士の保持力を発生できることで、リングサイズを指の太さに合わせながら指の外方から円滑に着脱できる。軸着部に介在させた金属薄板に変形膨出面を設け、この変形膨出面同士の形状記憶状態の当接部位を介してリング部材同士を止着固定していることにより、装着後には、形状記憶状態の当接部位によりリング部材同士の回転方向に対する負荷が高まり、この強い負荷によって閉じた状態のリング部材による保持力を向上して、指への装着状態を強固に維持して緩んだり脱落したりすることを防止できる。一方、変形膨出面同士のフラット状態の当接面を介してリング部材同士を止着解除していることにより、開閉操作時には、リング部材同士の回転方向に対する負荷を小さくし、軟らかく軽い力でリング部材同士を開閉操作できる。このため、指への装着時には指の太さに合わせたリング部材同士の微調整も容易になって優れた装飾性を維持できる。指から取外す際にも負荷が小さくなることにより、軽い力でリング部材同士を広げることができ、片手で簡単に操作可能となる。   According to the first aspect of the present invention, by providing a pair of thin metal plates between the bifurcated portion and the charging base portion, the metal thin plates are prevented from projecting to the outside, and the decorativeness as an accessory is maintained. Since the pair of metal thin plates can generate a holding force between the ring members, the ring size can be smoothly detached from the outside of the finger while adjusting the ring size to the thickness of the finger. By providing a deformed bulge surface on the thin metal plate interposed in the shaft attachment part, and fixing the ring members to each other via the contact portion in the shape memory state between the deformed bulge surfaces, The load in the rotating direction of the ring members increases due to the contact portion in the memory state, and the holding force by the ring member in the closed state is improved by this strong load, and the attachment state to the finger is firmly maintained to loosen or drop off Can be prevented. On the other hand, since the ring members are fixed and released via the flat contact surfaces between the deformed bulging surfaces, the load on the rotation direction of the ring members is reduced during the opening and closing operation, and the ring is soft and light. The members can be opened and closed. For this reason, at the time of mounting on the finger, fine adjustment of the ring members according to the thickness of the finger is facilitated, and excellent decoration can be maintained. When the load is removed from the finger, the ring members can be spread with a light force and can be easily operated with one hand.

なお、指輪本体が閉じた状態で変形膨出面同士の形状記憶状態を維持していることにより、指への装着状態におけるリング部材同士の保持力を向上して指への装着性を高め、リング部材同士が広がって指への止着が緩んで指先から抜け出たり、指輪本体が開閉方向に広がってリング部材の端部の間から指から外れることを防止できる。
In addition , by maintaining the shape memory state between the deformed bulging surfaces in a state where the ring body is closed, the holding force between the ring members in the mounting state on the finger is improved and the mounting property on the finger is improved. or it exits the fingertip spreads out between members loose fastening to the finger, that out of the finger from between the ends of the ring member ring body extends in the closing direction can be prevented.

さらには、金属薄板の変形膨出面同士を当接させて負荷を与え、二又部と装入基部との圧接面に金属薄板の外縁部が圧接面から突設しない状態で圧接させていることにより、一対のリング部材を円滑に開閉して容易に装着可能になり、金属薄板が外部に露出することがないため、装飾性や安全性にも優れている。
Furthermore , the deformed bulge surfaces of the metal thin plate are brought into contact with each other to give a load, and the outer edge portion of the metal thin plate is pressed against the pressure contact surface between the bifurcated portion and the charging base without protruding from the pressure contact surface. Thus, the pair of ring members can be opened and closed smoothly and can be easily mounted, and the metal thin plate is not exposed to the outside, so that the decorativeness and safety are excellent.

また、二又部、装入基部の各圧接面の摩擦面にリング部材を圧接させてこれらの間の摩擦抵抗を大きくできることから、二又部、装入基部のそれぞれに対してリング部材の回転を阻止できる。このため、リング部材同士の回転を防止して、リング部材の変形膨出面同士の形状記憶状態の当接部位による止着固定機能、又は変形防止面同士のフラット状態の当接部位による止着解除機能をそれぞれ高めることができる。
In addition , since the ring member can be pressed against the friction surface of each pressure contact surface of the bifurcated portion and the charging base portion to increase the frictional resistance between them, the rotation of the ring member with respect to the bifurcated portion and the charging base portion can be increased. Can be prevented. For this reason, the rotation of the ring members is prevented, and the fixation fixing function by the contact part in the shape memory state between the deformation bulge surfaces of the ring members, or the fixation release by the contact part in the flat state between the deformation prevention surfaces. Each function can be enhanced.

なお、指輪本体が開いた状態で変形膨出面同士のフラットな状態を維持していることにより、指輪本体を閉じた状態から開くときには、負荷を軽減してリング部材同士の止着を容易に解除できる。
In addition , by maintaining the flat state of the deformed bulge surfaces with the ring body open, when the ring body is opened from the closed state, the load is reduced and the ring members are easily released. it can.

請求項１に係る発明によると、変形膨出面を有する金属薄板をリング部材の二又部と装着基部との間にそれぞれ介在させ、指輪本体の閉じた状態で軸着部を軸着ピンで加締めて変形膨出面同士を形状記憶させた状態でリング部材同士を止着固定し、指輪本体の開いた状態で軸着部を軸着ピンで加締めて変形膨出部同士をフラットな状態でリング部材同士を止着解除していることによって組立てが簡単であり、指輪本体の開閉状態の加締めにより、金属薄板の変形膨出面を介してリング部材同士に異なる保持力を発揮させることができる。これにより、指輪本体の装着後には、形状記憶状態の当接部位によりリング部材同士の回転方向に対する負荷が高まり、この強い負荷によって閉じた状態のリング部材同士の保持力を向上して、指への装着状態を強固に維持して緩んだり脱落したりすることを防止できる。一方、開閉操作時には、リング部材同士の回転方向に対する負荷を小さくし、軟らかく軽い力でリング部材同士を開閉操作できる。また、金属薄板に対して、穴あけと同時にヒネリ工程で軸着方向に膨出変形加工を施すことができ、複雑な加工を経ることなく所定の形状の変形膨出面を容易に成形できる。

Assembling is easy because the ring members are released from each other, and by holding the ring body in the open / closed state, different holding forces can be exerted on the ring members via the deformed bulging surface of the thin metal plate. . As a result, after the ring main body is mounted, the load in the rotational direction between the ring members increases due to the contact portion in the shape memory state, and the holding force between the ring members in the closed state is improved by this strong load to the finger. It is possible to prevent loosening or falling off by firmly maintaining the mounting state of. On the other hand, at the time of opening / closing operation, the load with respect to the rotation direction of the ring members can be reduced, and the ring members can be opened / closed with a soft and light force. Further, the metal thin plate can be subjected to a bulging deformation process in the axial direction in the slack process at the same time as drilling, and a deformed bulging surface having a predetermined shape can be easily formed without complicated processing.

さらには、加工後の指輪本体の一対のリング部材の開閉操作を容易にしつつ、金属薄板の外部への露出を防ぐことで装飾性や安全性にも優れる。
Furthermore , it is excellent in decoration and safety by preventing the metal sheet from being exposed to the outside while facilitating the opening and closing operation of the pair of ring members of the ring body after processing.

請求項２に係る発明によると、二又部、装入基部の各圧接面に、梨地加工やローレット加工により摩擦面を容易に形成でき、これら摩擦面を介して、二又部、装入基部とリング部材との摩擦抵抗をそれぞれ大きくしてリング部材同士の回転を防止することができる。

The open / close ring (hereinafter referred to as a ring main body 1) has a pair of semi-annular ring members 2, 3, a metal thin plate 4, and a shaft attachment portion 5, and a base portion of the pair of ring members 2, 3 has the shaft attachment portion 5. As a result, the whole is formed into a circular shape, an elliptical shape, a rectangular shape, or the like. In the present embodiment, the ring body 1 is formed in a circular shape.

図５に示した一対のリング部材２、３は、金（１８Ｋ等）、プラチナ、シルバー等の貴金属素材により装飾的価値の高いデザインに形成される。図２（ａ）、図２（ｂ）に示すように、リング部材２、３の自由端部７、８側には装飾材９が設けられている。装飾材９は、例えば、ダイアモンド等の装飾性を有する宝石により形成され、自由端部７、８に形成された石座１０に嵌め込みや接着等の手段により取付けられる。   The pair of ring members 2 and 3 shown in FIG. 5 are formed in a design having a high decorative value by using a noble metal material such as gold (18K, etc.), platinum, or silver. As shown in FIGS. 2A and 2B, a decoration material 9 is provided on the free end portions 7 and 8 side of the ring members 2 and 3. The decoration material 9 is formed of, for example, a decorative gem such as diamond, and is attached to a stone base 10 formed on the free ends 7 and 8 by means such as fitting or adhesion.

図４、図５において、リング部材２の基部には、二又部１１又は装入基部１２がそれぞれ形成される。二又部１１は、一方のリング部材２の基部に二又状に設けられ、装入基部１２は、他方のリング部材３の基部に、二又部１１の間に装入可能な突状に形成される。   4 and 5, a bifurcated portion 11 or a charging base portion 12 is formed at the base portion of the ring member 2, respectively. The bifurcated portion 11 is provided in a bifurcated shape at the base portion of one ring member 2, and the charging base portion 12 is a protruding shape that can be inserted between the bifurcated portions 11 at the base portion of the other ring member 3. It is formed.

二又部１１に装入基部１２を装入するときには、これら二又部１１と装入基部１２との間に、一対の金属薄板４、４がそれぞれ介在される。さらに、各リング部材２、３の基部には、貫通孔からなる軸着部５が形成され、一対のリング部材２、３は、この軸着部５が軸着ピン１５により加締められていることで、軸着部５を介して回動自在に設けられている。   When the charging base 12 is inserted into the forked portion 11, a pair of thin metal plates 4, 4 are interposed between the forked portion 11 and the charging base 12, respectively. Further, a shaft attachment portion 5 formed of a through hole is formed at the base of each ring member 2, 3, and the pair of ring members 2, 3 is crimped by a shaft attachment pin 15. Thus, it is provided so as to be rotatable via the shaft attachment portion 5.

図３に示した金属薄板４は、例えば、ステンレスや鋼を材料として形成され、弾性、硬度及び耐磨耗性、加工容易性、耐食性などを考慮した上で、適正な材料により設けられる。図３（ａ）に示すように、金属薄板４は略六角形の外形からなり、図３（ｂ）、図３（ｃ）、図３（ｄ）において、軸着方向には変形膨出面２０が設けられ、この変形膨出面２０の中心には軸穴２１が穴あけ加工により形成される。図３（ａ）において、金属薄板４の外周には六角形の辺を成す外縁部２２と、この外縁部２２の間に多角形頂部２３が形成されている。   The metal thin plate 4 shown in FIG. 3 is formed of, for example, stainless steel or steel, and is provided with an appropriate material in consideration of elasticity, hardness, wear resistance, workability, corrosion resistance, and the like. As shown in FIG. 3A, the thin metal plate 4 has a substantially hexagonal outer shape. In FIGS. 3B, 3C, and 3D, the deformed bulging surface 20 is formed in the axial direction. A shaft hole 21 is formed in the center of the deformed bulging surface 20 by drilling. In FIG. 3A, an outer edge portion 22 having a hexagonal side is formed on the outer periphery of the thin metal plate 4, and a polygonal top portion 23 is formed between the outer edge portions 22.

図３の変形膨出面２０は、軸穴２１の穴あけ加工時にヒネリ工程を加えることにより、軸着方向に３次元的に変形膨出した状態になっている。これにより、図４、図５に示すように、異なる金属薄板４の変形膨出面２０、２０同士を当接させて外部より加締めによる力を加えたときに、開閉状態で変形膨出面２０同士の接触状態を変えることが可能になっている。   The deformed bulging surface 20 of FIG. 3 is in a state of three-dimensionally deforming and bulging in the axial direction by adding a knitting process when the shaft hole 21 is drilled. Accordingly, as shown in FIGS. 4 and 5, when the deformed bulging surfaces 20 and 20 of different thin metal plates 4 are brought into contact with each other and a force by caulking is applied from the outside, the deformed bulging surfaces 20 are opened and closed. It is possible to change the contact state.

このような変形膨出面２０の形状により、指輪本体１を閉じた状態で二又部１１をリング部材２、３の外部から強い力で叩いて加締めるようにすれば、図４（ａ）において、指輪本体１が閉じた状態で変形膨出面２０同士の形状記憶状態を維持し、これら変形膨出面２０同士の形状記憶状態の当接部位２７を介してリング部材２、３同士を止着固定することが可能となる。   With the shape of the deformed bulging surface 20, when the ring body 1 is closed and the forked portion 11 is squeezed with a strong force from the outside of the ring members 2 and 3, as shown in FIG. The shape memory state between the deformation bulge surfaces 20 is maintained in a state where the ring body 1 is closed, and the ring members 2 and 3 are fixedly fixed to each other through the contact portion 27 of the shape memory state between the deformation bulge surfaces 20. It becomes possible to do.

また、指輪本体１を開いた状態で二又部１１をリング部材２、３の外部から弱い力で叩いて加締めるようにすれば、図４（ｂ）において、指輪本体１が開いた状態で変形膨出面２０同士のフラットな状態の当接を維持し、これら変形膨出面２０同士のフラットな状態の当接面２８を介して、リング部材２、３同士を止着解除することが可能となる。   Further, when the ring body 1 is opened and the bifurcated portion 11 is squeezed with a weak force from the outside of the ring members 2 and 3, the ring body 1 is opened in FIG. 4 (b). It is possible to maintain the flat contact between the deformed bulge surfaces 20 and to release and fix the ring members 2 and 3 through the flat contact surface 28 between the deformed bulge surfaces 20. Become.

このようにして、図４に示すように、一対の金属薄板４、４は、変形膨出面２０、２０同士が当接されて負荷が与えられた状態で、二又部１１と装入基部１２とに設けられた圧接面２５、２６に配置される。
図５（ｂ）において、金属薄板４の外端部までの長さＬは、二又部１１と装入基部１２の幅距離Ｗよりも小さく形成されている。これにより、金属薄板４を圧接面２５、２６に配置したときには、この金属薄板４の外縁部２２が圧接面２５、２６よりも突出することがなく、この状態で金属薄板４の多角形頂部２３を圧接面２５、２６に圧接させたり、食い込ませた状態に設けることが可能になる。 In this way, as shown in FIG. 4, the pair of metal thin plates 4, 4 is in a state where the deformed bulging surfaces 20, 20 are in contact with each other and a load is applied, and the bifurcated portion 11 and the charging base 12. Are disposed on the pressure contact surfaces 25 and 26 provided on the surface.
In FIG. 5B, the length L to the outer end portion of the thin metal plate 4 is formed to be smaller than the width distance W between the bifurcated portion 11 and the charging base portion 12. Thereby, when the metal thin plate 4 is disposed on the pressure contact surfaces 25 and 26, the outer edge portion 22 of the metal thin plate 4 does not protrude beyond the pressure contact surfaces 25 and 26, and in this state, the polygonal top portion 23 of the metal thin plate 4 is provided. Can be provided in pressure contact with the pressure contact surfaces 25 and 26 or in a state of being bitten.

図６に示すように、二又部１１、装入基部１２の圧接面２５、２６には、それぞれ摩擦面３０、３１が設けられる。図６（ａ）において、摩擦面３０、３１は、梨地処理により機械的或は化学的に表面を荒らした状態に設けられ、これにより、処理前のフラット状の面に比較して金属薄板４との摩擦抵抗を大きくできる。
図６（ｂ）に示すように、摩擦面３０、３１は、ローレット状の凹凸面状に加工されて設けられていてもよく、この場合にも、図６（ａ）の場合と同様に、金属薄板４との摩擦抵抗を大きくできる。さらに、摩擦面は、これら以外の態様であってもよく、例えばドット状に設けられていてもよい。
これらの摩擦面３０、３１を加工する場合、表面粗さなどを変えることにより、金属薄板４との摩擦抵抗の大きさを適宜調節できる。 As shown in FIG. 6, friction surfaces 30 and 31 are provided on the pressure contact surfaces 25 and 26 of the bifurcated portion 11 and the charging base portion 12, respectively. In FIG. 6 (a), the friction surfaces 30 and 31 are provided in a state where the surface is mechanically or chemically roughened by a satin treatment, whereby the metal thin plate 4 is compared with a flat surface before the treatment. The frictional resistance can be increased.
As shown in FIG. 6 (b), the friction surfaces 30, 31 may be provided by being processed into a knurled uneven surface, and in this case as well, as in FIG. 6 (a), The frictional resistance with the metal thin plate 4 can be increased. Further, the friction surface may be in a mode other than these, and may be provided in a dot shape, for example.
When processing these friction surfaces 30 and 31, the magnitude of the frictional resistance with the metal thin plate 4 can be appropriately adjusted by changing the surface roughness and the like.

図３（ｂ）に示した金属薄板４の穴あけ加工（ヒネリ工程）加工前の板厚Ｔは、０．０８〜０．２７ｍｍの範囲の寸法であるとよく、より好ましくは、０．１４〜０．２６ｍｍの範囲であるとよい。この理由として、板厚Ｔが０．０８ｍｍ未満、及び０．２７ｍｍを超えると、それぞれ金属薄板４に十分な弾性力が得られなくなるためである。   The plate thickness T of the thin metal plate 4 shown in FIG. 3 (b) before drilling (sinking process) is preferably in the range of 0.08 to 0.27 mm, more preferably 0.14 to It is good in the range of 0.26 mm. This is because, if the plate thickness T is less than 0.08 mm and exceeds 0.27 mm, a sufficient elastic force cannot be obtained for the metal thin plate 4 respectively.

なお、金属薄板４は、六角形以外の形状であってもよく、例えば、四角形、菱形又は丸形などの各種形状に設けることもできる。この場合にも、穴あけ時のヒネリ工程により、軸着方向に変形膨出面２０を形成可能となる。
また、自由端部７、８側の装飾材９は、任意の大きさや数に設定したり、或は装飾材９を省略することもでき、これらにより所望の装飾性を有する指輪本体を設けることができる。 The thin metal plate 4 may have a shape other than a hexagon, and may be provided in various shapes such as a quadrangle, a rhombus, or a round shape. Also in this case, the deformed bulging surface 20 can be formed in the axial direction by the piercing process at the time of drilling.
Further, the decoration material 9 on the free ends 7 and 8 side can be set to an arbitrary size or number, or the decoration material 9 can be omitted, thereby providing a ring body having a desired decoration property. Can do.

次いで、上述した止着固定構造を有する開閉指輪の製造方法を述べる。
図１、図２の指輪本体１を製造する際には、図４、図５に示すように、一方のリング部材２の二又部１１の間に他方のリング部材３の装入基部１２を装入し、これら一対のリング部材２、３の基部を、軸着部５を介して軸着して指輪本体を構成する。
この場合、軸穴２１のヒネリ加工により変形膨出面２０を形成した一対の金属薄板４、４を、二又部１１と装入基部１２との間の圧接面２５、２６における摩擦面３０、３１にそれぞれ介在させた後に、指輪本体１の加締めをおこなう。 Next, a method for manufacturing an opening and closing ring having the above-described fastening and fixing structure will be described.
When the ring body 1 shown in FIGS. 1 and 2 is manufactured, as shown in FIGS. 4 and 5, the charging base portion 12 of the other ring member 3 is interposed between the bifurcated portions 11 of the one ring member 2. The base of the pair of ring members 2 and 3 is axially attached via the axial attachment portion 5 to constitute a ring body.
In this case, the pair of metal thin plates 4, 4 having the deformed bulging surface 20 formed by the knitting process of the shaft hole 21 are connected to the friction surfaces 30, 31 at the pressure contact surfaces 25, 26 between the bifurcated portion 11 and the charging base portion 12. The ring body 1 is caulked after being interposed in each.

この加締め時には、図４（ａ）において、指輪本体１の閉じた状態で適宜の工具により強い力で叩いて軸着部５を軸着ピン１５で加締めることで、変形膨出面２０同士を形状記憶させてその当接部位２７を当接させてリング部材２、３同士を止着固定でき、その結果、指輪本体１の閉じた状態を維持可能となる。
また、図４（ｂ）において、指輪本体１の開いた状態で適宜の工具により弱い力で叩いて軸着部５を軸着ピン１５で加締めることで、変形膨出面２０同士をフラット状態でその当接面２８を当接させてリング部材２、３同士を止着解除でき、その結果、指輪本体１を開くときにリング部材同士を容易に回動可能となる。 At the time of this caulking, in FIG. 4 (a), the ring body 1 is closed with an appropriate tool and is struck with a strong force to caulk the shaft attachment portion 5 with the shaft attachment pin 15 so that the deformed bulging surfaces 20 are aligned. The ring members 2 and 3 can be fastened and fixed by making the shape memory and the contact part 27 contact, and as a result, the closed state of the ring main body 1 can be maintained.
Further, in FIG. 4B, the deformed bulging surfaces 20 can be flattened by striking the shaft attaching portion 5 with the shaft attaching pin 15 by hitting with a weak force with an appropriate tool while the ring body 1 is open. The ring members 2 and 3 can be fixed and released by bringing the contact surface 28 into contact with each other. As a result, the ring members can be easily rotated when the ring body 1 is opened.

このように、一対の金属薄板４、４の変形膨出面２０同士を当接させて金属薄板４同士に負荷を与え、二又部１１と装入基部１２との圧接面２５、２６に金属薄板４の外縁部２２が、圧接面２５、２６から突設しない状態で圧接させている。そして、金属薄板４の外縁部２２を含む全面が、摩擦面３０、３１に圧接した状態となる。   In this way, the deformation bulge surfaces 20 of the pair of metal thin plates 4 and 4 are brought into contact with each other to apply a load to the metal thin plates 4, and the metal thin plates are applied to the pressure contact surfaces 25 and 26 between the bifurcated portion 11 and the charging base 12. The four outer edge portions 22 are in pressure contact with each other without protruding from the pressure contact surfaces 25 and 26. Then, the entire surface including the outer edge portion 22 of the metal thin plate 4 is brought into pressure contact with the friction surfaces 30 and 31.

上述した指輪本体１を手指に装着する場合には、図２（ａ）に示すように、一対のリング部材２、３を軸着部５を中心に相互に回転させて指輪本体１を開いた状態にし、指の外側又は先方側から所望の装着位置に配置させて、図２（ｂ）に示すように、リング部材２、３を閉じる方向に回転させるようにする。これにより、爪にネイルアートを施している場合や、関節が太い場合にも、指の外側から容易に指輪本体１を着脱できる。   When the ring main body 1 described above is attached to a finger, as shown in FIG. 2A, the ring main body 1 is opened by rotating the pair of ring members 2 and 3 around the shaft attachment portion 5. Then, the ring members 2 and 3 are rotated in the closing direction as shown in FIG. 2 (b). Thereby, when the nail art is given to the nail or when the joint is thick, the ring body 1 can be easily detached from the outside of the finger.

その際、図４、図５に示すように、一対のリング部材２、３を、軸着部５を中心に回転しながら、図１の指輪本体を拡縮してリングサイズを調節し、指の太さにフィットさせた状態で装着できる。図４の変形膨出面２０同士の当接部位２７の形状記憶による保持力により、リング部材２、３同士の過度な回転を防止して指への圧迫を防止する。そのため、優れた装着性を維持しつつ各種の径の指輪として使用でき、使用者の十指の何れの指への装着も可能になる。   At that time, as shown in FIGS. 4 and 5, while rotating the pair of ring members 2 and 3 around the shaft mounting portion 5, the ring body of FIG. Can be installed in a thickness-fitted state. The holding force by the shape memory of the contact portion 27 between the deformed bulging surfaces 20 in FIG. 4 prevents excessive rotation of the ring members 2 and 3 and prevents pressure on the finger. Therefore, it can be used as a ring of various diameters while maintaining excellent wearability, and can be worn on any of the ten fingers of the user.

図１、図２において、リング部材２、３同士を回転させることにより、自由端部７、８同士を重ね合わせた状態でリングサイズを調節できるため、指を包囲した状態を維持して装飾性を高め、指からの抜け出しも防止する。   1 and 2, by rotating the ring members 2 and 3, the ring size can be adjusted while the free ends 7 and 8 are overlapped with each other. And prevents slipping out of the finger.

図３、図４に示すように、装着後には、変形膨出面２０同士の当接部位２７が形状記憶状態で当接していることで、この形状記憶による復元力によりこれら変形膨出面２０同士が強固に当接してリング部材２、３同士の回転方向に強い負荷が働く。これによって、強固な止着固定状態を発揮し、指輪本体１を開状態から閉状態まで回転させたときにも、変形膨出面２０同士の当接部位２７の形状が形状記憶に基づいて元の状態に戻ることでリング部材２、３の保持力が向上する。   As shown in FIG. 3 and FIG. 4, after the mounting, the contact portions 27 of the deformation bulge surfaces 20 are in contact with each other in the shape memory state. A strong load is exerted in the rotational direction between the ring members 2 and 3 by firmly contacting. Thereby, even when the firm fastening state is exhibited and the ring body 1 is rotated from the open state to the closed state, the shape of the contact portion 27 between the deformed bulging surfaces 20 is based on the shape memory. By returning to the state, the holding force of the ring members 2 and 3 is improved.

上記の場合、二又部１１、装入基部１２の各圧接面２５、２６に摩擦面３０、３１を設け、この摩擦面３０、３１にリング部材２、３を圧接させているため、これらの摩擦抵抗を大きくできる。これにより、圧接面２５、２６に対するリング部材２、３の回動を阻止でき、前述した変形膨出面２０同士の形状記憶状態の当接部位２７を介してリング部材２、３同士を止着固定する場合、変形膨出面２０同士のフラット状態の当接面２８を介してリング部材２、３同士を止着解除する場合の何れにおいても、当接部位２７同士や当接面２８同士の相対的な回転やずれを防止し、リング部材２、３による前記機能性を高めることができる。   In the above case, the friction surfaces 30 and 31 are provided on the pressure contact surfaces 25 and 26 of the bifurcated portion 11 and the charging base 12, and the ring members 2 and 3 are pressed against the friction surfaces 30 and 31, respectively. The frictional resistance can be increased. Thereby, rotation of the ring members 2 and 3 with respect to the pressure contact surfaces 25 and 26 can be prevented, and the ring members 2 and 3 are fixedly fixed to each other via the contact portion 27 in the shape memory state between the deformed bulging surfaces 20 described above. In the case where the ring members 2 and 3 are fixed to each other via the contact surfaces 28 in the flat state between the deformed bulging surfaces 20, the contact portions 27 and the contact surfaces 28 are relative to each other. Therefore, the functionality by the ring members 2 and 3 can be improved.

さらに、金属薄板４の多角形頂部２３が、点接触により圧接面２５、２６に圧接し、加締めによってこの接触部分には大きい押圧力が生じている。このとき、金属薄板４の硬度が貴金属製のリング部材２、３よりも大きいことから、多角形頂部２３が圧接面２５、２６を塑性変形させながら食い込む。そのため、金属薄板４と圧接面２５、２６との滑りを一層防止し、金属薄板４と、二又部１１、装入基部１２との相対的な回動を阻止する。
これらのことから、リング部材２、３同士の間の回動阻止力が飛躍的に向上して所定の当接状態を強く保持できる。 Further, the polygonal top portion 23 of the thin metal plate 4 is brought into pressure contact with the pressure contact surfaces 25 and 26 by point contact, and a large pressing force is generated at the contact portion by caulking. At this time, since the hardness of the metal thin plate 4 is larger than that of the ring members 2 and 3 made of noble metal, the polygonal top portion 23 bites in while the pressure contact surfaces 25 and 26 are plastically deformed. Therefore, the sliding of the metal thin plate 4 and the pressure contact surfaces 25 and 26 is further prevented, and the relative rotation of the metal thin plate 4 with the bifurcated portion 11 and the charging base portion 12 is prevented.
For these reasons, the rotation prevention force between the ring members 2 and 3 is greatly improved, and the predetermined contact state can be strongly maintained.

これによって、指輪本体１を装着したり指から取外す際、一対のリング部材２、３同士を回転させるときには、変形膨出面２０同士のフラット状態の当接面２８を介して、軟らかく軽い力で図２（ａ）や図２（ｂ）の状態まで回転でき、簡単に指に着脱可能となる。   As a result, when the ring body 1 is mounted or removed from the finger, the pair of ring members 2 and 3 are rotated with a soft and light force through the flat contact surface 28 between the deformed bulging surfaces 20. It can be rotated to the state of 2 (a) and FIG. 2 (b) and can be easily attached to and detached from the finger.

一方、指輪本体１を指に装着した後は、前記のように変形膨出面２０同士の形状記憶状態の当接部位を介してリング部材２、３同士の回転を防止し、指輪本体１の強固な装着状態を保持できる。これによって、指輪本体１が、自然の力や外部からの不用意な力でみだりに回転することがなく、指から自然に緩んだり脱落したりすることを防止できる。指輪本体１には、常時閉鎖する方向の力が働くことがないため、指を締付けることがなく、長時間装着した場合にも、指に痛みが生じたり違和感を生じることがないため、自然な装着感を維持できる。   On the other hand, after the ring main body 1 is attached to the finger, the ring members 2 and 3 are prevented from rotating with each other through the contact portions in the shape memory state between the deformed bulging surfaces 20 as described above, and the ring main body 1 is strengthened. Can maintain the proper wearing state. Thus, the ring body 1 can be prevented from being loosened or dropped off naturally from the finger without being rotated with natural force or careless external force. Since the ring body 1 does not always have a force in the closing direction, the finger is not tightened, and even when the finger is worn for a long time, the finger does not hurt or feel uncomfortable. A feeling of wearing can be maintained.

二又部１１と装入基部１２との圧接面２５、２６に、この圧接面２５、２６から金属薄板４の外縁部２２が突出しない状態で食い込ませていることにより、金属薄板４が外部に露出することがなく、装飾的価値を低下させることがない。このように円形で外部に突起物のない形状に加えて、装飾材９を設けていることでより優れた装飾性を発揮する。また、指輪本体１を楕円形や角形に設けた場合には、円形とは異なる特有の装飾性を発揮可能になる。   Since the outer edge 22 of the metal thin plate 4 does not protrude from the pressure contact surfaces 25, 26 to the pressure contact surfaces 25, 26 of the forked portion 11 and the charging base 12, the metal thin plate 4 is exposed to the outside. It is not exposed and does not degrade the decorative value. Thus, in addition to the shape which is circular and has no protrusions on the outside, the decorative material 9 is provided, so that more excellent decorative properties are exhibited. Moreover, when the ring main body 1 is provided in an elliptical shape or a rectangular shape, it is possible to exhibit a unique decorative property different from a circular shape.

さらに、装飾性を高めるためにリング部材２、３を表面研磨することもでき、この場合、金属薄板４まで研磨が及ぶことがないため金属薄板４が傷付くことがなく、金属薄板４による保持力の低下を防ぎ、表面に傷が生じて手指を傷付けるおそれもない。   Further, the ring members 2 and 3 can be surface-polished in order to enhance the decorativeness. In this case, the metal thin plate 4 is not damaged because the metal thin plate 4 is not polished, and the metal thin plate 4 is held. It prevents the loss of force and there is no risk of scratching the surface and damaging the fingers.

なお、図示しないが、一対のリング部材２、３同士を回転させて自由端部７、８同士を重ね合わせて環状にし、この指輪本体１にチェーンを通すようにすれば、ペンダントとしても使用できる。   Although not shown, if the pair of ring members 2 and 3 are rotated so that the free ends 7 and 8 are overlapped to form a ring and the chain is passed through the ring main body 1, it can be used as a pendant. .
