There is a known ornament having a decorative member containing a jewel or the like and a frame member, with the decorative member supported so as to be swingable relative to the frame member (hereinafter, ornaments with this structure may be referred to as swinging ornaments). In swinging ornaments, the frame member and the decorative member are each provided with an engagement part, and the decorative member can be swung by engaging the engagement parts of both. Conventionally, the engagement part of the frame member is, for example, an independent part made separately from the part that forms the main body of the frame member. The engagement part of the frame member is welded and fixed to a predetermined part of the main body of the frame member by a method such as brazing or laser heating.

However, when the engaging portion is fixed to the main body of the frame member by methods such as brazing or laser heating, distortion is likely to occur in the brazed or laser heated area. In this case, even if the engaging portion of the decorative member is engaged with the engaging portion of the frame member, there is little immediate problem in normal use of the ornament, but if the aforementioned distortion occurs, there is a possibility that the strength of the portion where the engaging member is fixed to the main body of the frame member will be reduced.

In contrast, the ornament of the present disclosure comprises a frame member which is a pressed product of a metal plate, and a decorative member supported on the frame member so as to be swingable. The frame member includes two first engaging parts each having a first through hole, and the decorative member includes two second engaging parts each having a second through hole. One first engaging part and one second engaging part are connected to each other so as to bring the inner surface of the first through hole into contact with the inner surface of the second through hole, and the other first engaging part and the other second engaging part are connected to each other so as to bring the inner surface of the first through hole into contact with the inner surface of the second through hole. Here, press working is a general term for a processing technique in which a metal plate is supplied between a pair of dies and a load is applied to the metal plate by the dies, thereby performing processing such as punching, bending, and drawing. In addition, a pressed product refers to an article obtained by press working.

The ornament of the present disclosure has the above structure, which prevents distortion caused by brazing or laser heating, and therefore improves the strength of the portion where the frame member supports the decorative member compared to conventional swinging ornaments. The first engagement portion of the frame member is a part of the frame member, which is a pressed product of a metal plate, and therefore the first engagement portion is prevented from falling off the frame member. In addition, because the strength of the portion where the frame member supports the decorative member so that it can swing is improved, it is believed that the swinging effect of the decorative member can be easily obtained even with long-term use.

In conventional swingable ornaments, frame members are often manufactured by casting using the lost wax method, and have not been manufactured by press processing until now. In the manufacturing method of ornaments disclosed herein, a frame member including an engagement portion of a swingable ornament is formed by press processing from a single metal plate. By forming the frame member of the ornament by press processing a single metal plate, the first engagement portion is formed as a part of the frame member, which is a press processed product of a single metal plate, and therefore, unlike conventional swingable ornaments, there is no need to attach the engagement portion to the main body of the frame member by brazing or laser heating. Therefore, compared to conventional manufacturing methods, the strength of the portion where the frame member supports the decorative member so that it can swing is improved.

The method of manufacturing a personal accessory of the present disclosure forms a blank by punching a metal plate. The blank includes a frame main body that constitutes a part of the frame member, and a first engagement portion that extends from the main body outer edge, which is the outer edge of the frame main body. The method of manufacturing a personal accessory of the present disclosure folds the blank so that the first engagement portion of the blank extends toward the rear side. By folding the first engagement portion toward the rear side, the strength of the portion where the frame main body and the first engagement portion are connected is likely to be improved compared to when this portion is fixed by conventional methods such as welding. Furthermore, since the attachment work of the engagement portion is not required, manufacturing is easier.

In conventional swinging ornaments manufactured by casting using the lost wax method, if the thickness of the desired ornament is too thin (for example, 0.5 mm or less), it is difficult to inject molten metal into every corner of the mold, making it difficult to manufacture a thin swinging ornament. In contrast, the manufacturing method for ornaments disclosed herein, which forms a frame member by press processing, makes it possible to form the frame member from a thin metal plate, making it possible to manufacture a swinging ornament that is thinner than conventional ornaments. Furthermore, the manufacturing method for ornaments disclosed herein makes it possible to reduce the weight of the swinging ornaments compared to when swinging ornaments of approximately the same design are manufactured using conventional manufacturing methods.

In addition, in the lost wax method, since molten metal is poured into a mold for casting, air bubbles are likely to be present in the base metal. In contrast, in the manufacturing method disclosed herein, the frame member is formed by pressing a metal plate, so the presence of air bubbles in the base metal of the frame member is suppressed. Therefore, in the swinging ornament obtained by the manufacturing method disclosed herein, the entire frame member including the first engagement portion is stronger than a swinging ornament manufactured by a conventional manufacturing method. In addition, since it is believed that work hardening occurs due to the press processing, it is believed that the strength of the ornament itself is higher than that of the frame member of a swinging ornament obtained by a conventional manufacturing method. Therefore, it is easy to obtain a swinging ornament that maintains its strength even when it is lightweight.

In a swinging ornament manufactured by a conventional manufacturing method, the decorative member suspended from the frame member swings in response to external vibration. However, there were cases where the duration of the swinging of the decorative member was variable. This is thought to be due to the following. As mentioned above, in a swinging ornament manufactured by a conventional manufacturing method, air bubbles are likely to be trapped in the engaging portion of the frame member, and the inner circumferential surface of the engaging portion of the frame is often rough. It is difficult to polish this inner circumferential surface. For this reason, the engaging portion of the decorative member may get caught on the engaging portion of the frame member due to this roughness. Also, as mentioned above, in a conventional manufacturing method, the engaging portion of the frame member is attached to the main body of the frame member by brazing or laser heating, and the attachment of the engaging portion requires skill. For this reason, depending on the worker, the accuracy of attaching the pair of engaging portions to the main body of the frame member may be low. Furthermore, the engaging portion of the frame member may be formed by cutting a linear metal material (metal wire) with a circular cross section to a predetermined length and bending it into a ring shape. In this case, the accuracy of the ring shape may be low.

In contrast, the manufacturing method of the disclosed ornamental product forms the frame member by pressing one metal plate. Therefore, it is possible to manufacture an ornamental product in which the frame member including the frame body and the first engagement part are integrally formed as different parts of one metal plate. The metal plate, which is the material of the ornamental product, is, for example, rolled, so that there are few air bubbles in the base metal as in the case of manufacturing by casting. Therefore, the occurrence of roughness on the inner circumferential surface of the first through hole of the first engagement part is suppressed. In addition, since punching is performed, the inner circumferential surface of the first through hole of the first engagement part is smoother than when manufactured by casting. As a result, it is easier to suppress the occurrence of catching between the second engagement part of the decorative member and the first engagement part of the frame member. Furthermore, since the first engagement part and the frame body of the frame member are continuously and integrally formed from one metal plate, the precision of the position, size, shape, etc. of the first engagement part is easier to improve compared to when manufacturing by a method of fixing parts to each other by welding, etc. Therefore, compared to swinging ornaments obtained by conventional manufacturing methods, the decorative member will swing with respect to the frame member with greater durability. In addition to the above, it is possible to make the thickness of the swinging ornament, including the first engagement portion of the frame member, thinner. In this case, it is possible to reduce the contact area between the second engagement portion of the decorative member and the first engagement portion of the frame member, and frictional resistance can be kept small. In this respect, too, the decorative member will swing with respect to the frame member with greater durability.

The manufacturing method disclosed herein enables mass production and reduces the number of steps required for the finishing process, making it possible to reduce manufacturing costs compared to conventional manufacturing methods for swinging accessories.

Below, an example of a preferred embodiment of the ornament of the present disclosure will be described with reference to the drawings. Note that the ornament of the present disclosure is not limited to the embodiments described below, and various modifications are possible as long as it has substantially the same configuration as the ornament of the present disclosure and provides similar effects.

In this disclosure, "integral" means formed from one member, and does not include the concept of two members being joined together to form one unit.

In this disclosure, the term "ornament" includes gemstones (natural gemstones, synthetic gemstones, artificial gemstones, imitation gemstones, natural stones, etc.), and in particular, natural gemstones, synthetic gemstones, artificial gemstones, imitation gemstones, and natural stones are collectively referred to as gemstones. It is preferable that the ornament be selected from gemstones from the viewpoint of the aesthetic appearance of the accessory.

Natural gemstones include gemstones that occur in nature, such as diamonds, rubies, sapphires, and quartz. Natural gemstones also include treated gemstones, which have been enhanced, altered, or otherwise processed.
A synthetic gemstone is a gemstone that has the same or similar chemical properties, physical properties, and internal structure as a natural stone and is created artificially. Synthetic gemstones are also called man-made gemstones.
Although artificial gemstones do not exist in nature, they have certain chemical and physical properties and internal structure, and are created using substances different from natural gemstones, such as cubic zirconia (CZ) and yttrium-arsenic (YAG).
An imitation gemstone is a gemstone that has the same color, appearance, etc. as a natural gemstone, but has different chemical properties and physical structure; for example, it is made from glass, plastic, ceramics, etc. to imitate a natural gemstone.
Natural stones are stones that are produced in nature other than natural gemstones.

In this disclosure, "plate-like" refers to a plate-like shape. For example, it refers to a shape that has a generally uniform thickness overall.

In this disclosure, the term "approximately" when describing a shape is a concept that includes that shape and shapes close to that shape.

In the present disclosure, in order to explain the relative positional relationship of each part of the ornament, three orthogonal directions (X direction, Y direction, Z direction) are defined based on the ornament. The X direction includes two mutually opposite directions (X1 direction, X2 direction), the Y direction includes two mutually opposite directions (Y1 direction, Y2 direction), and the Z direction includes two mutually opposite directions (Z1 direction, Z2 direction).
The Z direction is set based on, for example, the vertical direction when the ornament of the present disclosure is in a position in which the frame member supports the decorative member so that the decorative member can swing. The Y direction is set based on, for example, the direction from the front side to the back side of the ornament of the present disclosure. The front side of the ornament refers to, for example, the side on which the front of the decorative body is placed, and even if the front of the decorative body is tilted upward, it refers to the side on which the front of the decorative body is placed. The X direction is set to a direction perpendicular to each of the Z direction and the Y direction.
In the following description, the upward direction of the ornament includes the Z1 direction shown in Figs. 1 to 3, and a direction closer to the Z1 direction than the intermediate direction of each direction. The downward direction of the ornament includes the Z2 direction shown in Figs. 1 to 3, and a direction closer to the Z2 direction than the intermediate direction of each direction. The rightward direction of the ornament includes the X1 direction shown in Figs. 1 to 3, and a direction closer to the X1 direction than the intermediate direction of each direction. The leftward direction of the ornament includes the X2 direction shown in Figs. 1 to 3, and a direction closer to the X2 direction than the intermediate direction of each direction. The forward direction of the ornament includes the Y2 direction shown in Figs. 2 and 3, and a direction closer to the Y2 direction than the intermediate direction of each direction. The rearward direction of the ornament includes the Y1 direction shown in Figs. 2 and 3, and a direction closer to the Y1 direction than the intermediate direction of each direction.

First Embodiment
Fig. 1 to Fig. 3 are diagrams showing an example of an ornament according to this embodiment. The necklace 1 shown in Fig. 1 to Fig. 3 is an example of an ornament. Fig. 1 shows a front view of the necklace 1, Fig. 2 shows a perspective view of the necklace 1 as seen from the front side, and Fig. 3 shows a perspective view of the necklace 1 as seen from the back side. The necklace 1 comprises a chain 3, which is an example of a string-like member, and a pendant top 2 (an example of an ornament body), and the pendant top 2 is suspended from the chain 3. Figs. 1 to 3 focus on the pendant top 2, which is the main part, for illustration.

The pendant top 2 comprises a frame member 10, which is a pressed product of a metal plate, and a decorative member 20 supported so as to be swingable relative to the frame member 10. The decorative member 20 comprises a jewel 21, which is an example of a decorative object, and a base member 22 that holds the jewel 21 in place. The base member 22 has four claws 221, which hold the jewel 21 in place.

The frame member 10 has two first engagement parts 13 each having a first through hole 131 formed therein. The two first engagement parts 13 are arranged side by side in the left-right direction on the rear side of the frame member 10. The base member 22 has two second engagement parts 23 each having a second through hole 231 formed therein. The two second engagement parts 23 are arranged in relative positions (i.e., positions in a left-right relationship when viewed from the front side of the jewel 21) sandwiching the jewel 21. One first engagement part 13 and one second engagement part 23 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 are in contact with each other. The other first engagement part 13 and the other second engagement part 23 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 are in contact with each other. When the two first engagement parts 13 and the two second engagement parts 23 are engaged and connected to each other, the base member 22 that holds the jewel 21 in place is suspended so as to be swingable relative to the frame member 10.

As shown in Figs. 1 to 3, the frame member 10 has a frame body 11. The two first engagement parts 13 each extend from the body outer edge part 110, which is the outer edge part of the frame body 11 (the side end face at the outer edge of the pressed metal plate), to the rear side.

As shown in FIG. 1, the outer edge 110 of the frame body 11 includes a concave portion that is curved concavely in the Z1 direction when viewed from a direction parallel to the Y1 direction from the front side to the rear side, and a convex portion that is curved in the same direction (Z1 direction) as the concave portion when viewed from a direction parallel to the Y1 direction. The concave portion and the convex portion face each other. When viewed from the front side of the frame body 11, it has an inverted V shape with a curved portion.

As shown in FIG. 3, at least a part of the body end 113, which is the end of the frame body 11 (the end including the body outer edge 110), is warped toward the rear side. In the example of FIG. 3, the body end 113 of the frame body 11 is warped toward the rear side at the above-mentioned concave and convex parts of the body outer edge 110. When viewed from the rear side, the part of the frame body 11 that is inside the body outer edge 110 (the part inside the range surrounded by the body outer edge 110) is recessed toward the front side.

The two first engagement parts 13 extend from the outer edge 110 of the main body at the end 113 of the main body that is curved toward the rear side. As shown in Figs. 1 to 3, the two first engagement parts 13 extend from spaced apart locations in the concave portion of the outer edge 110 of the main body, sandwiching the innermost part of the concave portion. Here, the innermost part of the concave portion refers to the most concave part of the concave shape.

As shown in Figs. 1 to 3, the frame member 10 has two rear frame portions 12 extending from the main body outer edge 110 to the rear side. The two rear frame portions 12 extend to the rear side from a part of the main body outer edge 110 at the main body end 113 that is curved toward the rear side. In the example of Fig. 3, the two rear frame portions 12 extend from spaced apart locations on the convex portion of the main body outer edge 110, spaced apart from each other across the apex of the convex portion. The apex of the convex portion refers to the most convex part of the convex shape.

The rear frame portion 12 is provided in a shape that follows the frame body 11 from the top of the frame body 11 to the periphery of the vertical center. The rear frame portion 12 has an upper frame 121 that extends from the outer edge portion 110 of the frame body 11 near the top to the rear side, a lower frame 122 that extends from the vertical center of the frame body 11 to the rear side, and an intermediate frame 123 that is provided between the rear end portions of the upper frame 121 and the lower frame 122. The rear frame portion 12 is approximately rectangular in shape, with the vertical dimension longer than the front-rear dimension, and forms an opening 124 in the area surrounded by the upper frame 121, the lower frame 122, the intermediate frame 123, and the frame body 11. In the example of Figures 2 and 3, the opening 124 penetrates in the left-right direction and has an approximately rectangular shape that is long in the vertical direction. The chain 3 is inserted into this opening 124.

The two rear frame parts 12 extending toward the rear side have a joint part where they are joined to each other at a location away from the outer edge part 110 of the main body of the frame main body 11. For example, the upper frame 121 of one rear frame part 12 and the upper frame 121 of the other rear frame part 12 are joined by a joint part not shown. At the joint part, the two rear frame parts 12 are joined to each other by a method such as welding (e.g., brazing or laser heating). The joint part joining one upper frame 121 to the other upper frame 121 may be provided at one or more locations on the frame main body 11. Also, the joint part may be provided intermittently or continuously.

The cross-section of the lower periphery of the first engagement portion 13 of the frame body 11 cut in a plane perpendicular to the up-down direction has a generally V-shape that widens from the front side to the rear and has a curved portion. The frame body 11 has a similar cross-sectional shape from the bottom to the top. On the other hand, the cross-section of the upper frame 121 and lower frame 122 of the rear frame portion 12 cut in a plane perpendicular to the front-to-rear direction has a generally rectangular shape. The cross-section of the middle frame 123 cut in a plane perpendicular to the up-to-down direction also has a generally rectangular shape.

The thickness of one side of the approximately V-shaped frame body 11 (the distance between the opposing faces in the front-to-rear direction of the V-shaped frame body 11) and the thickness in the left-right direction of the rear frame part 12 (the distance between the opposing faces in the left-to-right direction of the rear frame part 12) are set, for example, in the range of 0.3 mm to 0.4 mm. The thickness of the rear frame part 12, for example, when measured at the lower frame 122, may be 0.2 mm or more, or 0.25 mm or more. This thickness may also be 0.5 mm or less, 0.4 mm or less, or 0.35 mm or less. In the present disclosure, the thickness of the frame member 10 is not particularly limited, and may be set to a thickness suitable for the purpose depending on the design, strength, etc. of the accessory.

The first engagement portion 13 is formed integrally and continuously from the same metal plate as the frame body 11. Here, "formed integrally and continuously" means that the first engagement portion 13 is formed by continuously connecting one and the same metal plate without being divided by the interposition of a different material. As shown in FIG. 3, for example, the first engagement portion 13 has a first ring portion 132 surrounding the first through hole 131 and a first intermediate portion 133 extending from the main body outer edge portion 110 of the frame body 11 to the back side. The first intermediate portion 133 is interposed between the ring outer edge portion 134, which is the outer edge portion of the first ring portion 132, and the main body outer edge portion 110. That is, the first engagement portion 13 has the first intermediate portion 133 extending from the main body outer edge portion 110 to the back side and the first ring portion 132 extending from the first intermediate portion 133 to the back side, and the frame body 11 and the first ring portion 132 are arranged at positions separated from each other. Here, the frame body 11 and the first ring portion 132 being disposed at a distance from each other means that the frame body 11 and the first ring portion 132 are not in contact with each other, and there is a distance between the first ring portion 132 and the frame body 11. In the example of FIG. 3, the first engagement portion 13 is disposed at a position lower than the lower frame 122 and in an area inside the lower frame 122. The first engagement portion 13 extends from the front side to the back side of the pendant top 2 and has a shape bent from the end of the main body. By providing the first intermediate portion 133, for example, when forming the frame member 10, the first engagement portion 13 can be easily bent toward the back side. As a result, the shape of the first ring portion 132 is easily suppressed from being distorted in the bending process described below, and the advantage of being able to stably maintain the shape of the first ring portion 132 is obtained.

Here, the width of the first engagement portion 13 is defined as the width in a direction perpendicular to the thickness direction of the metal plate forming the first engagement portion 13, and the width in a direction perpendicular to the direction in which the first engagement portion 13 extends from the main body outer edge portion 110. In this case, as shown in FIG. 3, the width of the first engagement portion 13 at the first intermediate portion 133 is smaller than the width at the first ring portion 132. In the example of FIG. 3, the first intermediate portion 133 is formed in a substantially rectangular shape. The vertical dimension of the first intermediate portion 133 is shorter than the outer diameter of the first ring portion 132. The first intermediate portion 133 is provided in a shape in which the center position of the first intermediate portion 133 is located on a virtual line that is the shortest distance from the center of the first ring portion 132 to the frame main body 11.

The first ring portion 132 has a circular ring shape (one example of a shape having an arc-shaped curved portion) that allows the second engagement portion 23 of the decorative member 20 to be inserted into the central first through hole 131. The two first ring portions 132 are arranged on the left and right sides of the frame member 10 with their first through holes 131 facing each other.

As shown in FIG. 1, an imaginary plane V is defined in the frame member 10. The imaginary plane V is parallel to the direction from the front side to the rear side (Y1 direction), and is a plane that passes through the concave portion of the main body outer edge portion 110 of the frame main body 11 when viewed from the front side. As shown in FIG. 1 to FIG. 3, the frame member 10 has a shape that is plane-symmetrical with respect to this imaginary plane V.

The two first engagement portions 13 each extend in a direction parallel to the imaginary plane V (including parallel and nearly parallel states). The two first through holes 131 formed in the two first engagement portions 13 are positioned so as to overlap each other when viewed from a direction perpendicular to the imaginary plane V (X1 direction, X2 direction).

The base member 22 includes a base body 220 to which the jewel 21 (an example of an ornament) is fixed, and two second engagement parts 23 arranged on either side of the base body 220. The two second engagement parts 23 are arranged on both sides of the jewel 21 so as to be in relative positions. Each second engagement part 23 includes a second ring part 232 surrounding the second through hole 231, and a plate-shaped second intermediate part 233 extending from the base body 220. The second intermediate part 233 is interposed between the second ring part 232 and the base body 220. A circular opening is provided in the center of the base body 220, and the jewel 21 is fixed and held to the base member 22 with the culet part of the jewel 21 protruding from the opening of the base body 220.

The second intermediate portion 233 is a connecting portion that connects the base body portion 220 and the second ring portion 232. The two second intermediate portions 233 have symmetrical shapes and extend outward from the base body portion 220. In one example, the second intermediate portion 233, the base body portion 220, and the second ring portion 232 are continuously and integrally formed. The second intermediate portion 233 extends from the base body portion 220 and is arranged at an incline with respect to the front surface of the jewel 21. The second ring portion 232 is also inclined in the same manner as the inclination of the second intermediate portion 233. This inclination angle is an angle at which the base body portion 220 is inclined with respect to the front surface of the jewel 21, and may be in the range of more than 0° and not more than 90° with respect to the surface of the base body portion 220 on which the claw portion 221 is provided. The inclination angle may be, for example, 5° or more, or 10° or more. It may also be 60° or less, or 45° or less. The base member 22 can be modified according to the purpose, such as the connection length of the second intermediate portion 233 and the presence or absence of an inclined portion. For example, it is also possible to form the base main body portion 220 and the second ring portion 232 integrally without providing the second intermediate portion 233 in the base member 22, and to form the second ring portion 232 extending directly from the base main body portion 220.

The plate-like second intermediate portion 233 may be twisted, for example. The decorative member 20 can swing even without twisting the second intermediate portion 233, but the aesthetics of the accessory may be improved by providing an appropriate twist to the second ring portion 232. The second intermediate portion 233 may be twisted in its entirety or in part. By providing an appropriate twist to the second intermediate portion 233, the table surface of the jewel 21 can be tilted diagonally upward when the base member 22 holding the jewel 21 in a fixed position is suspended. In this case, the inclination angle of the table surface of the jewel 21 can be set to, for example, 5° to 45° (or 10° to 20°), thereby further improving the aesthetics of the accessory.

Next, an example of a preferred embodiment of the method for manufacturing a personal accessory according to the present disclosure will be described using the method for manufacturing the necklace 1 shown in FIG. 1 and other figures. FIG. 4 is a flow chart for explaining an example of the method for manufacturing a personal accessory according to this embodiment.

In the manufacturing method of the ornament according to this embodiment, the frame member 10 in particular is formed by press processing. Specifically, as shown in FIG. 4, the manufacturing method of the necklace 1 includes a step of preparing a metal plate (metal plate preparation step: ST10), a step of forming the frame member 10 by press processing (frame member formation step: ST20), a step of forming an insertion part in the first engagement part 13 of the frame member 10 (insertion part formation step: ST30), a step of preparing the decorative member 20 (decorative member preparation step: ST40), and a step of connecting the second engagement part 23 of the decorative member 20 to the first engagement part 13 of the frame member 10 (connection step: ST50).

(Metal plate preparation process: ST10)
The process of preparing a metal plate is a process of preparing a plate-shaped metal material to be processed according to the desired ornament. In this process, for example, a metal plate that has been rolled or the like is prepared. The shape of the metal plate is not limited to a flat metal plate cut in advance, and also includes a coil-shaped metal plate. For example, from the viewpoint of processability, the metal plate preferably has a substantially rectangular cross-sectional shape in the thickness direction. The thickness of the metal plate may be 0.2 mm or more, 0.5 mm or less, 0.4 mm or less, or 0.35 mm or less. The material (metal type) of the metal plate is not particularly limited, and may be any metal material, such as a metal selected from the group consisting of silver, gold, platinum, copper, and iron, an alloy of these metals (e.g., an alloy mainly made of gold and containing at least one of silver and copper), and an alloy mainly made of these metals and containing other metals (e.g., an alloy mainly made of gold and containing palladium, etc., an alloy mainly made of copper and containing zinc, etc.). The metal plate to be prepared may be made of a desired metal material depending on the type of ornament to be manufactured. In this disclosure, the term "main" component refers to the component with the highest content among the alloys composed of two or more metal elements.

(Frame member forming process: ST20)
The process of forming the frame member 10 further includes a step of forming a blank material (blank material forming step: ST21), a step of processing the first through hole 131 of the first engagement portion 13 (first through hole processing step: ST22), a step of folding the blank material (folding step: ST23), and a step of joining the two rear side frame portions 12 folded by the folding step (joining step: ST24).

(Blank material forming process: ST21)
The blank forming process is a process for forming a blank by punching (shearing) one metal plate. In this process, in order to obtain a blank having a desired shape, the prepared metal plate is fed into a die and the metal plate is punched out by generating a shear phenomenon.

The blank material forming process may be a single-stage process to obtain a blank material of the desired shape. For example, when punching a metal plate, the outer shape and fine details may be punched out. Alternatively, the cutting process may be a multi-stage process to obtain a blank material of the desired shape. For example, the blank material forming process may be a multi-stage process to obtain a blank material of the desired shape after punching out the outer shape, and then punching out the fine details such as the first through hole 131.

Alternatively, the blank material forming process may obtain a blank material of the desired shape by, for example, shearing and deformation. In this case, a blank material of the desired shape may be obtained in a single process. For example, when punching a metal plate, the outer shape and details may be punched out, and the cross-sectional shape of at least one of the frame main body 11 and the rear frame part 12 may be formed into the desired shape. A blank material of the desired shape may also be obtained in a multi-stage process. For example, after punching out the outer shape, details such as the first through hole 131 may be punched out, and then the cross-sectional shape of at least one of the frame main body 11 and the rear frame part 12 may be formed into the desired shape in a multi-stage process. In this disclosure, drawing and bending are collectively referred to as deformation.

(First through hole processing step: ST22)
FIG. 5 is a cross-sectional view showing an example of the shape of the inner surface of the first through hole 131. As shown in FIG.
In the first through hole processing step, at least a part of the inner surface 136 of the first through hole 131 is inclined so that the diameter of the first through hole 131 becomes smaller as it moves inward from the opening 135 of the first through hole 131. The processing of the first through hole 131 may be performed, for example, by cutting the inner surface of the first through hole 131 with a rotary blade, or by press processing using a mold. The first through hole 131 of the first engagement part 13 that passes through the first through hole 131 has a cross-sectional shape perpendicular to the circumferential direction that is approximately trapezoidal in the area on the inner circumferential surface side, tapering toward the inner circumferential surface. By making it into such a shape, the swinging of the second ring part 232 of the decorative member 20 that contacts the inner circumferential surface side is more likely to be sustained. The cross-sectional shape perpendicular to the circumferential direction of the first ring part 132 is not limited to this, and various cross-sectional shapes can be adopted. The first through hole processing step (ST22) may be performed in parallel with the blank piece forming step (ST21) described above in the same press working step.

(Folding process: ST23)
The bending process is a process of obtaining a frame member 10 formed into a desired shape by bending the blank obtained through the first through hole processing process (ST22). This process is performed, for example, by press processing using a mold. The frame member 10 has a three-dimensional shape. In this process, the blank is folded so that the two first engagement parts 13 and the two rear frame parts 12 of the blank are extended toward the rear side. That is, in the folding process, at least a part of the main body end part 113, the two first engagement parts 13, and the two rear frame parts 12 are folded toward the rear side together with respect to the blank so that at least a part of the main body end part 113 (the end part including the main body outer edge part 110) of the frame main body 11 is warped toward the rear side. The main body end part 113 folded together with the first engagement part 13 and the rear frame part 12 in the folding process includes at least a part adjacent to the first engagement part 13 and a part adjacent to the rear frame part 12.

By bending, the rear frame portion 12 becomes the side wall of the frame member 10. The frame member 10 has a three-dimensional shape with a space surrounded by the frame main body 11 and the rear frame portion 12. When the necklace 1 is viewed from the front, the rear frame portion 12 becomes difficult to see. Similarly, when the necklace 1 is viewed from the front, the first engagement portion 13 also becomes difficult to see.

After bending, the bending angle between the frame body 11 and the rear frame portion 12, and the bending angle between the frame body 11 and the first engagement portion 13 (first intermediate portion 133) should be approximately 90° (for example, 80° to 100°, preferably 85° to 95°). From the viewpoint of aesthetics, this bending angle is preferably an obtuse angle of approximately 90°. In this disclosure, the bending angle is the angle from the frame body 11, and represents the outer angle in the bending direction of the rear frame portion 12 and the first engagement portion 13 (first intermediate portion 133). The order in which the rear frame portion 12 and the first engagement portion 13 are bent is not limited, and they may be bent simultaneously, or one of the portions may be bent first. The bending may be performed in multiple stages or in one stage.

The blank forming process (ST21) and the folding process (ST23) may be performed in separate dies, or may be performed in the same die. These processes may be performed by progressive press working, or by single press working using a foot press.

(Joining process: ST24)
In the joining step, the two rear frame portions 12 bent toward the rear side in the bending step (ST23) are joined at least at one location (e.g., a location away from the main body outer edge portion 110). This joining of metals is performed by, for example, brazing, welding, or the like.

Note that if any of the steps in the frame member forming process ST20 are unnecessary due to the shape of the desired frame member, that step may be omitted.

(Insertion part forming process: ST30)
The insertion portion forming step forms an insertion portion in a part of a member (first ring portion 132) surrounding the first through hole 131 in each first engagement portion 13 of the frame member 10 formed in the frame member forming step (ST20). For example, the insertion portion forming step may form the insertion portion in a part of the first ring portion 132 by a method such as heating with a laser, cutting with a rotary blade or the like, or cutting with a tool such as scissors.

(Decorative member preparation process: ST40)
The decorative member preparation process is a process for preparing the decorative member 20 to be attached to the frame member 10, and further includes a process for forming the base member 22 (base member formation process: ST41) and a process for fixing and holding the jewel 21 on the base member 22 (fixing and holding the decorative body: ST42).

(Base member forming process: ST41)
The base member forming process is a process for obtaining the base member 22 from a metal plate. When the base member 22 is formed by press working, a predetermined metal plate is prepared in this process. The metal plate may be made of the same material as the metal plate prepared for producing the frame member 10, or may be made of a different material. Then, the base member 22 is formed by performing a predetermined press working process (shearing, bending, drawing, etc.) on the metal plate.

The base member 22 is integrally formed with the base main body 220, two second engagement parts 23 (second ring part 232, second intermediate part 233), and four claw parts 221. Specifically, a blank for the base member is first obtained by shearing a metal plate. The blank for the base member is provided with the base main body 220 having four radially extending claw parts 221 at approximately equal intervals and a substantially circular opening in the center. The blank for the base member is also provided with a substantially rectangular second intermediate part 233 that is disposed on either side of the base main body 220 and extends from between the two claw parts 221 in a direction away from each other, and a second ring part 232 that is formed in a ring shape and has a second through hole 231 in the center and extends from the tip of the second intermediate part 233. Next, in the base member forming process, the base main body 220 is drawn into a dish-shaped shape that allows the placement of the jewel 21. In addition, the second intermediate portion 233 is twisted in a direction inclined toward the front side. Through these processes, the base member 22 is obtained. The base member 22 may be produced by progressive press processing, or may be produced by a single press process using a foot press (foot-operated press). The base member 22 may be produced by casting other than press processing. From the viewpoint of production costs, etc., it is preferable to produce the base member 22 by press processing.

Depending on the desired base member 22, the base member 22 to be formed may be a base member 22 having a second engaging portion 23 without a second intermediate portion 233, or a base member 22 having a second intermediate portion 233 without a twisted portion. When obtaining a base member 22 without a second intermediate portion 233 and a base member 22 without a twisted portion, the step of twisting the second intermediate portion 233 is omitted.

(Decorative body fixing and holding process: ST42)
The step of fixing and holding the ornamental body is a step of placing the gemstone 21 on the base body 220 of the obtained base member 22 and fixing and holding it. Fig. 7 is a diagram showing an example of the base member 22 before the gemstone 21 is fixed. Fig. 8 is a diagram showing an example of the ornamental member 20 in which the gemstone 21 is fixed to the base member 22. In the example of Fig. 8, the gemstone 21 is a faceted gemstone. The gemstone 21 is placed on the base body 220 with the culet protruding from a substantially circular opening provided in the base body 220. Next, the four claws 221 are inclined toward the front side of the gemstone 21 to fix and hold it.

(Linking step: ST50)
The connecting step is a step of connecting the second engaging portion 23 of the decorative member 20 and the first engaging portion 13 of the frame member 10. Specifically, the second engaging portion 23 of one of the decorative member 20 and the first engaging portion 13 of one of the frame members 10 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 come into contact with each other. In addition, the other second engaging portion 23 of the decorative member 20 and the other first engaging portion 13 of the frame member 10 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 come into contact with each other. The connecting step is an example of an attachment step of attaching the second engaging portion 23 of the decorative member 20 to the first engaging portion 13 of the frame member 10.

Specifically, the connecting step (ST50) includes an insertion step (ST51) in which the second ring portion 232 of the second engaging portion 23 is inserted into the first through hole 131 from the insertion portion of the two first engaging portions 13 formed in the insertion portion forming step (ST30), and an insertion portion blocking step (ST52) in which the insertion portions of the two first engaging portions 13 are blocked after the insertion step (ST51). In the insertion step (ST51), the annular second ring portion 232 is inserted into the insertion portion formed in the first engaging portion 13, and the inner peripheral edges of the first ring portion 132 and the second ring portion 232 are brought into contact with each other in a direction in which the circumferential direction of the first ring portion 132 intersects with the circumferential direction of the second ring portion 232. Then, in the insertion portion blocking step (ST52), both ends of the insertion portion of the first ring portion 132 are butted against each other and pressed so that the gap is reduced, and the first ring portion 132 is plastically deformed into an annular shape. This allows the left and right annular second ring portions 232 to be connected and engaged with the left and right first ring portions 132, respectively. After the first ring portions 132 are plastically deformed as described above, the butted ends of the first ring portions 132 can be joined together by brazing, laser heating, or the like, if necessary.

(Other processes)
The above manufacturing method may include other steps (e.g., a finishing step). The finishing step is a step in which the obtained frame member 10 and base member 22 are finished by performing various processes such as polishing. In the finishing step, after the polishing process, a plating process (e.g., plating with a platinum group metal such as rhodium) may be performed as necessary. In addition, a string-like member insertion step is performed in which a chain 3, which is an example of a string-like member, is inserted into the top of the frame member 10, thereby obtaining a necklace 1, which is an ornament from which a pendant top 2 is suspended.

Through the above steps, the necklace 1 according to this embodiment is obtained, in which the decorative member 20 including the jewel 21 is suspended from the frame member 10 and supported so that it can swing.

(Summary of the first embodiment)
As described above, the necklace 1 according to this embodiment has the following features, for example.

The necklace 1 according to this embodiment has a frame member 10, which is a pressed product of a metal plate, and a decorative member 20 supported so as to be swingable relative to the frame member 10. The frame member 10 includes two first engagement parts 13 each having a first through hole 131 formed therein, and the decorative member 20 includes two second engagement parts 23 each having a second through hole 231 formed therein. One first through hole 131 and one second through hole 231 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 are in contact with each other, and the other first engagement part 13 and the other second engagement part 23 are connected to each other so that the inner surface of the first through hole 131 and the inner surface of the second through hole 231 are in contact with each other.
With this configuration, the two first engagement portions 13 are part of the frame member 10, which is a pressed product of a single metal plate, and are not fixed to the main body of the frame member 10 by a method such as brazing, thereby increasing the strength of the portion of the frame member 10 that supports the decorative member 20 in a swingable manner.

In the necklace 1 according to this embodiment, the frame member 10 includes a frame body 11, and a front side and a back side are defined with respect to the frame body 11. The two first engagement parts 13 extend from a main body outer edge part 110, which is the outer edge part of the frame body 11, to the back side.
According to this configuration, the two first engagement portions 13 each extend toward the rear side of the frame body 11, so that when the necklace 1 is viewed from the front side, the two first engagement portions 13 can be hidden on the rear side of the frame body 11, improving the aesthetic appearance.

The necklace 1 according to this embodiment has a frame member 10 and a decorative member 20 supported by the frame member 10 so as to be capable of swinging.
The frame member 10 includes a frame main body 11 and two first engagement parts 13 each having a first through hole 131 formed therein, and the decorative member 20 includes two second engagement parts 23 each having a second through hole 231 formed therein. Each first engagement part 13 is connected to a corresponding one of the second engagement parts 23 by contacting the inner surface of the first through hole 131 with the inner surface of the second through hole 231, and each first engagement part 13 has a first ring part 132 surrounding the first through hole 131 and a first intermediate part 133 extending from the first ring part 132. The frame main body 11 and the first ring part 132 are disposed at positions spaced apart from each other and are connected by the first intermediate part 133, and at least a part of the frame main body 11, the first intermediate part 133, and the first ring part 132 are continuously and integrally formed from the same metal plate.
With this configuration, the two first engagement portions 13 are part of the frame member 10, which is a pressed product of a single metal plate, and are not fixed to the main body of the frame member 10 by a method such as brazing, thereby increasing the strength of the portion of the frame member 10 that supports the decorative member 20 in a swingable manner.

In the necklace 1 according to this embodiment, at least a part of the main body end 113, which is the end (the end including the main body outer edge 110) of the frame main body 11, is curved toward the rear side. The two first engagement parts 13 extend toward the rear side from the main body outer edge 110 of the main body end 113 curved toward the rear side.
According to this configuration, the first engagement portion 13 extends from the outer edge 110 of the main body end 113 warped toward the rear side to the rear side, so that when the necklace 1 is viewed from the front side, it is possible to hide the step between the first engagement portion 13 and the outer edge 110 of the main body, improving the aesthetics. In addition, since at least a part of the main body end 113 is warped toward the rear side, the shape of the frame member 10 can be given a sense of volume and three-dimensionality, which also improves the aesthetics. Furthermore, since at least a part of the main body end 113 is warped toward the rear side, the strength of the frame main body 11 can be increased even if the thickness of the pressed metal plate is thin.

In the necklace 1 according to this embodiment, the outer edge 110 of the frame body 11 includes a concave portion that is curved concavely when viewed in a direction parallel to the Y1 direction from the front side to the back side. The end 113 of the frame body 11 is curved toward the back side in the concave portion. The two first engagement portions 13 are spaced apart in the concave portion, and extend from spaced apart positions sandwiching the innermost part of the concave portion.
With this configuration, it is possible to position the decorative member 20 inside the recessed portion of the main body outer edge 110. In addition, since the main body end 113 of the frame main body 11 is curved toward the rear side in the recessed portion, the strength of the frame main body 11 can be increased even if it has an inverted V-shape.

In the necklace 1 of this embodiment, an imaginary plane V is defined that is parallel to the Y1 direction from the front side to the back side and passes through the concave portion, and in the frame member 10, at least the concave portion of the main body outer edge portion 110 and the two first engagement portions 13 have shapes that are plane-symmetrical with respect to the imaginary plane V.
With this configuration, the strength of the frame body 11 can be maintained while improving the aesthetic appearance.

In the necklace 1 according to this embodiment, the two first engagement parts 13 each extend parallel to the imaginary plane V. The two first through holes 131 formed in the two first engagement parts 13 are positioned so as to overlap each other when viewed from a direction perpendicular to the imaginary plane V (the X1 direction and the X2 direction).
With this configuration, the decorative member 20 can be stably swung around an imaginary swing axis that extends in a direction perpendicular to the imaginary plane V and passes through the two first through holes 131 .

In the necklace 1 according to this embodiment, the frame member 10 includes two rear frame parts 12 extending from the outer edge 110 of the frame body 11 to the rear side. The outer edge 110 of the frame body 11 includes a convex part that is curved in the same direction as the concave part when viewed from a direction parallel to the Y1 direction from the front side to the rear side. The end 113 of the frame body 11 is warped toward the rear side at the convex part. The two rear frame parts 12 extend from separate locations in the convex part, sandwiching the apex of the convex part. The two rear frame parts 12 are joined to each other at at least one location of the frame body 11 (e.g., a location away from the outer edge 110 of the frame body).
According to this configuration, the rear frame portion 12 extends from the main body outer edge portion 110 of the main body end portion 113 curved toward the rear side to the rear side, so that when the necklace 1 is viewed from the front side, it is possible to hide the step between the rear frame portion 12 and the main body outer edge portion 110, improving the aesthetics. In addition, since the main body end portion 113 is curved toward the rear side in the convex portion, the strength of the frame main body 11 can be increased even if the thickness of the pressed metal plate is thin. Furthermore, since the two rear frame portions 12 extending from the positions separated by the apex of the convex portion are joined to each other at at least one position of the main body outer edge portion 110, the strength of the frame member 10 can be further increased.

In the necklace 1 according to this embodiment, the first engagement portion 13 includes a first ring portion 132 surrounding the first through hole 131 and a first intermediate portion 133 extending from the main body outer edge portion 110 of the frame main body 11. The first intermediate portion 133 is interposed between a ring outer edge portion 134, which is the outer edge portion of the first ring portion 132, and the main body outer edge portion 110. When the width of the first engagement portion 13 is defined as the width in a direction perpendicular to the thickness direction of the metal plate forming the first engagement portion 13 and the width in a direction perpendicular to the direction in which the first engagement portion 13 extends from the main body outer edge portion 110, the width of the first engagement portion 13 at the first intermediate portion 133 is smaller than the width at the first ring portion 132.
With this configuration, even if the size of the first ring portion 132 is large due to the large size of the first through hole 131, the width of the first intermediate portion 133 is smaller than the width of the first ring portion 132, making it easier to bend the blank material so that the first intermediate portion 133 extends toward the back side of the frame main body 11.

The manufacturing method of the necklace 1 according to this embodiment includes a frame member forming process (ST20) in which a frame member 10 including two first engagement portions 13, each having a first through hole 131 formed therein, is formed by pressing a single metal plate, and a connecting process (ST50) in which one second engagement portion 23 of a decorative member 20 including two second engagement portions 23, each having a second through hole 231 formed therein, is connected to one first engagement portion 13 of the frame member 10 so that the inner surfaces of the first through holes 131 and the second through holes 231 come into contact, and the other second engagement portion 23 of the decorative member 20 is connected to the other first engagement portion 13 of the frame member 10 so that the inner surfaces of the first through holes and the second through holes come into contact.
With this configuration, the two first engagement portions 13 are formed as part of the frame member 10, which is a pressed product of a single metal plate, so that the strength of the portion of the frame member 10 that supports the decorative member 20 in a swingable manner can be increased compared to when the parts of the engagement portions are fixed to the main body of the frame member 10 by a method such as soldering.

In the manufacturing method of the necklace 1 according to this embodiment, the frame member forming process (ST20) includes a blank material forming process (ST21) in which a metal plate is punched to form a blank material having two first engagement portions 13 extending from the main body outer edge portion 110 of the frame main body 11 of the frame member 10, and a folding process (ST23) in which the blank material is folded so that the two first engagement portions 13 of the blank material extend toward the back side relative to the frame main body 11.
With this configuration, two first engagement portions 13 extending toward the rear side are formed by the bending process (ST23), thereby increasing the strength of the portion of the frame member 10 that supports the decorative member 20 in a swingable manner compared to when the parts of the engagement portions are fixed to the opposite side of the frame main body 11 by a method such as soldering.

In the manufacturing method of the necklace 1 according to this embodiment, the bending process (ST24) includes bending the main body end 113, which is the end of the frame main body 11 including the main body outer edge portion 110, including the portion adjacent to the first engagement portion 13, and the two first engagement portions 13 together toward the rear side so that at least a portion of the main body end 113 is warped toward the rear side.
According to this configuration, the main body end 113 including the portion adjacent to the first engaging portion 13 and the first engaging portion 13 are bent toward the rear side together in the folding step (ST24). This makes it difficult for a step to occur at the folding point between the main body end 113 adjacent to the first engaging portion 13 and the first engaging portion 13. Therefore, it is possible to suppress a decrease in strength of the folding point and to improve the aesthetic appearance.

In the manufacturing method of the necklace 1 according to this embodiment, the frame member forming process (ST20) includes a first through hole processing process (ST22) prior to the bending process (ST23), in which at least a portion of the inner surface 136 of the first through hole 131 is processed to be inclined so that the diameter of the first through hole 131 becomes smaller as it moves inward from the opening 135 (FIG. 5) of the first through hole 131.
According to this configuration, since machining can be performed on a flat, plate-shaped blank material, the inner surface of the first through hole 131 can be machined with high precision.

Second Embodiment
FIG. 9 is a diagram showing an example of a frame member 10A of an ornament according to the second embodiment, showing a perspective view seen from the back side. The second embodiment is a modified example of the first embodiment. The ornament according to the second embodiment is provided with a restricting portion 137 in the first engagement portion 13. Apart from the provision of this restricting portion 137, it has the same structure as the necklace 1 described in the first embodiment. In order to explain the main parts, the ornament according to the second embodiment will be explained using the frame member 10A shown in FIG. 9. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals and explanations will be omitted, and components different from those in the first embodiment will be explained.

In the accessory according to this embodiment, the restricting portion 137 provided on the first engaging portion 13 restricts the swing range of the second engaging portion 23 by not allowing it to pass through the second through hole 231 of the connected second engaging portion 23. For example, as shown in FIG. 9, the restricting portion 137 extends from the ring outer edge portion 134 of the first ring portion 132.

If the base member 22, which holds the jewel 21 in place in the range from the rear side to the upper side of the first ring portion 132, swings too much, the jewel 21 may get caught between the frame member 10 and the second ring portion 232 when it reaches the highest point on the rear side of the first ring portion 132. If such a catch occurs, it is considered that the durability of the swinging of the base member 22 will decrease. By providing the restricting portion 137 on the first engagement portion 13, even if the base member 22 swings significantly in the range from the rear side to the upper side, the restricting portion 137 does not pass through the second through hole 231, and the swinging range of the second ring portion 232 is limited. This makes it easier to avoid the above-mentioned catch, and effectively suppresses the decrease in the durability of the swinging of the base member 22.

The restricting portion 137 is preferably provided in a range from the rear side of the first ring portion 132 to the upper side, up to the first intermediate portion 133. In the frame member 10A shown in FIG. 9, the restricting portion 137 is provided on the upper side of the first ring portion 132. The restricting portion 137 extends toward the top side of the frame member 10, and has a rounded arc shape at the tip. The shape of the restricting portion 137 is not limited to this, and the position and shape of the restricting portion 137 are not particularly limited as long as it is possible to prevent the base member 22 from swinging too much and the second ring portion 232 from getting caught between the frame member 10 and the first ring portion 132. The restricting portion 137 can also be provided in a structure that extends from the frame member 10 toward the first ring portion 132. In this case, the number of places where bending processing is performed increases, so in terms of the deterioration of the function and accuracy of the restricting portion 137, it is preferable to have a structure that extends from the ring outer edge portion 134 of the first ring portion 132.

The manufacturing method of the accessory according to the second embodiment is generally the same as the manufacturing method of the necklace 1 according to the first embodiment, except that the first engagement part 13 is provided with a restricting part 137. Even when the first engagement part 13 is provided with a restricting part 137, the first engagement part 13 is bent by folding the blank material so that the first engagement part 13 extends toward the rear side of the frame body 11.

Third Embodiment
FIG. 10 is a diagram showing an example of a frame member 10B of an ornament according to the third embodiment, showing a perspective view seen from the back side. The third embodiment is a modified example of the first embodiment. In the ornament according to the third embodiment, the first intermediate portion 133 of the first engagement portion 13 extends in a direction inclined downward from the main body outer edge portion 110 of the frame main body 11, and otherwise has the same structure as the necklace 1 described in the first embodiment. In addition, the ornament according to the third embodiment will be described using the frame member 10B shown in FIG. 10 in order to explain the main parts. Hereinafter, the same components as those in the first embodiment will be given the same reference numerals and explanations will be omitted, and components different from these embodiments will be described.

In the third embodiment, the first intermediate portion 133 of the first engagement portion 13 extends in a direction tilted downward from the main body outer edge portion 110 of the frame main body 11. Therefore, even if the decorative member 20 swings significantly from the rear upward, the first intermediate portion 133 extending at an angle downward will collide with the second engagement portion 23 (second ring portion 232) before the second engagement portion 23 of the decorative member 20 swings significantly from the rear upward toward the front. This makes it possible to prevent the second engagement portion 23 of the decorative member 20 from swinging significantly from the rear upward toward the front, making it less likely that the above-mentioned snagging will occur.

The manufacturing method of the accessory according to the third embodiment is generally the same as the manufacturing method of the necklace 1 according to the first embodiment, except that the extension direction of the first intermediate portion 133 relative to the frame body 11 is different. Even though the extension direction of the body end portion 113 relative to the frame body 11 is different from that of the first embodiment, the bending process of the first engagement portion 13 is performed by bending the frame member 10B so that the first engagement portion 13 extends toward the rear side of the frame body 11.

(Other Modifications)
The number of rear frame parts 12 provided on the outside of the frame main body 11 is not limited to two, and may be, for example, three or four. The number of rear frame parts may be determined according to the shape of the target frame member. The shape of the frame main body when viewed from the front is not limited to an inverted V shape, and may be a rhombus, a circle, an oval, an oblong, a horseshoe, a teardrop, or the like, which may be determined according to the shape of the target frame member. In addition, the position of the first engagement part extending from the frame main body may be determined according to the shape of the target frame member. In addition, it is also possible to attach an ornament such as a jewel to the frame main body of the frame member.

In the above embodiment, an example of a necklace 1 having a pendant top 2 and a chain 3 has been described as an example of a personal accessory. In addition to this, the personal accessory of the present disclosure may be other personal accessories such as pierced earrings, earrings, brooches, necktie clips, etc., so long as the accessory supports a decorative member so that it can swing relative to a frame member. Of these, either a necklace or earrings is preferable. In this disclosure, a necklace is a general term for neck accessories including pendants, and earrings is a general term for ear accessories including earrings and pierced earrings.

In the above embodiment, the first ring portion 132 of the frame member 10 and the second ring portion 232 of the decorative member 20 have an overall ring shape. In addition, the ornament of the present disclosure may be formed so that when the first ring portion of the frame member and the second ring portion of the decorative member are connected, the portion where these ring portions contact each other has an arc-shaped (ring-shaped) shape, and the other portion has a non-arc-shaped shape. In addition, the above-mentioned ornament is described as a case where one base member is suspended from one frame member. In addition, the ornament of the present disclosure may be an ornament in which two or more base members are suspended from a frame member. The decorative member may be a member that is supported to be swingable on the frame member for decoration, and is not limited to a form in which a decorative body such as a jewel is fixed to a base member. For example, two second engagement portions may be integrally formed on the main body of the decorative member formed of the desired material such as metal.

Although an example of a preferred embodiment of the present disclosure has been described above, the ornament and the manufacturing method thereof of the present disclosure are not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible within the scope of the spirit of the present disclosure.
