In the case of manufacturing a frame member in a conventional accessory such as that described in Patent Document 1, generally, a mold is formed from a master mold made of wax, and molten metal is poured into the mold for casting. A lost wax method is used. By using this lost-wax casting (hereinafter abbreviated as lost-wax casting), it is possible to integrally cast a three-dimensional shape with one mold, so that the frame main body and the left and right retaining ring portions can be separated. A frame member having a complicated shape can be stably manufactured.

On the other hand, when manufacturing a frame member using lost-wax casting, the original model must be manufactured with wax, and molten metal is poured into every corner of the space in the mold formed by melting the wax. Because of the need, it has been difficult to form sharp points or shapes on frame members, which are very small parts. For this reason, for example, when the frame member is manufactured by lost-wax casting, the left and right retaining ring portions provided on the frame member are, for example, the inner circumference of the retaining ring portion when viewed in a cross section orthogonal to the circumferential direction of the retaining ring portion. The part had a rounded shape.

However, if the inner peripheral portions of the left and right retaining ring portions are rounded, when the hanger member is oscillatably held by the left and right retaining ring portions of the frame member, the hanger member will swing slightly as described above. In some cases, troubles such as deterioration of the movement to move and even failure to produce small rocking motions may occur, and these troubles have been major causes of defective products.

In addition, in order to make the inner peripheral portions of the left and right retaining ring portions of the frame member have a sharp shape, first, round cans having a sharp inner peripheral portion are press-molded as the retaining ring portions with the frame main body. are separately manufactured, and then the two obtained round jump rings are fixed to predetermined positions of the frame main body by brazing.

However, when the round jump ring is fixed to the frame main body by brazing afterward as described above, a problem of strength may arise in the fixing portion between the round jump ring and the frame main body. In addition, since the jump ring and the frame main body are very small, fixing these members by brazing requires many years of experience and skill, and the work itself takes time and effort. I needed it. For this reason, there is a drawback that it tends to cause a decrease in productivity and an increase in production cost. In addition, since fixing by brazing is performed manually, product defects may occur due to misalignment of the fixing position of the round jump ring or bending of the fixed attitude of the round jump ring.

On the other hand, in the accessory of the present disclosure, the frame member is a pressed metal product ( press molded body). In the present disclosure, fine pressed products for accessories, in which the frame main body and the retaining ring are integrally formed, have become feasible for the first time as a result of repeated improvements in press working technology.

The hanger members suspended from the frame member as described above are composed of a pedestal portion for fixing the jewelry, and a pair of left and right annular rockers disposed on the left and right sides of the pedestal portion and engaged with a pair of retaining ring portions. and a dynamic ring portion. The hanger member is suspended swingably from the frame member by hooking the inner peripheral portions of the left and right swing ring portions to the inner peripheral portions of the holding ring portion.

In such an accessory according to the present disclosure, at least the frame main body portion and the left and right retaining ring portions of the frame member are provided in a single metal press work, so that the inner peripheral portions of the left and right retaining ring portions are It can be stably formed into a sharply pointed shape. Therefore, when the hanger member is suspended from the left and right holding ring portions of the frame member, the contact area between the holding ring portion and the swing ring portion of the hanger member can be reduced, and the holding ring portion and the swing ring portion can be separated from each other. can reduce the frictional resistance between As a result, it is possible to stably cause the hanger member to swing slightly (finely) with respect to the frame member. In addition, since there is no need to braze the frame main body and the retaining ring of the frame member, the production work of the frame member is not affected by many years of experience and skill level. It is possible to shorten the time, reduce production costs, stabilize quality, and reduce product defects.

In the accessory of the present disclosure, the retaining ring portion may have a tapered shape that tapers radially inward of the retaining ring portion when viewed in a cross section perpendicular to the circumferential direction of the retaining ring portion. . Further, the swing ring portion may have a tapered shape that tapers inward in the radial direction of the swing ring portion when viewed in a cross section orthogonal to the circumferential direction of the swing ring portion. This makes it possible to more stably cause the hanger member to swing slightly with respect to the frame member. Also, the small rocking motion of the hanger member can be continued for a longer period of time.

In the accessory of the present disclosure, the pressed frame member may have a pair of left and right support arm portions that connect the frame body portion and the retaining ring portion. For example, after the primary processed product of the frame member is produced by press molding, the support arm portion can be deformed when bending the primary processed product to form the retaining ring portion in a desired orientation (orientation). . As a result, the frame member can be stably manufactured without causing distortion in the retaining ring portion formed into a predetermined annular shape by press molding. Further, since the frame member is provided with the support arm portion, it is possible to make it difficult for the hanger member to come into contact with the frame body portion when the hanger member swings slightly. It is possible to prevent the small swinging motion of the hanger member from being hindered.

In the accessory of the present disclosure, the frame body has a frame-like shape with an open center when viewed from the front of the frame member, and the support arm extends from the frame body at right angles to the circumferential direction of the frame body. It may extend in the direction By suspending the hanger member from the left and right support arm portions of the frame member, a small swing motion of the hanger member can be stably generated.

In the accessory of the present disclosure, the support arm portion may be formed with a constant thickness from the frame body portion to the retaining ring portion. The length dimension from the frame body portion to the retaining ring portion in the supporting arm portion may be larger than the thickness dimension of the supporting arm portion and smaller than the inner diameter dimension of the retaining ring portion. The width dimension of the support arm portion may be larger than the length dimension of the support arm portion and smaller than the outer diameter dimension of the retaining ring portion. Moreover, the thickness dimension of the support arm portion may be 0.15 mm or more and 0.35 mm or less. The length dimension from the frame body portion to the retaining ring portion in the support arm portion may be 0.10 mm or more and 0.50 mm or less. The width dimension of the support arm portion may be 0.30 mm or more and 1.20 mm or less. By forming the support arm portions in this way, the frame member can be manufactured stably without causing distortion in the retaining ring portion. In addition, it is possible to make it difficult for the hanger member to come into contact with the frame main body when the hanger member swings slightly.

In the jewelry of the present disclosure, the support arm extends from the upper half of the inner periphery of the frame body. Further, in a front view of the frame member, the retaining ring portion has a lower end portion on which the swing ring portion is hooked, and an upper end portion arranged on the opposite side to the lower end portion. , the left and right retaining ring portions may be symmetrically arranged in an inclined direction with respect to the vertical direction so that the interval between the upper ends of the left and right retaining ring portions is narrower than the interval between the lower end portions of the left and right retaining ring portions. good. Thereby, even when the support arm portion is provided on the inner peripheral portion of the frame main body portion, it is possible to easily secure a large interval between the lower end portions on which the swing ring portion is hooked by the left and right holding ring portions. As a result, the hanger member can be easily formed to be large, and a larger jewel can be swung smaller with respect to the frame member.

The necklace 1 shown in FIGS. 1 and 2 includes a chain 5 that is a cord-like member and a pendant top 10 that is an accessory body.

The pendant top 10 has a hanger member 20 to which a diamond as a jewel 21 is fixed and held, and a frame member 30 to support the hanger member 20 in a suspended state.
The hanger member 20 includes a jewel 21, a pedestal portion 22 on which the jewel 21 is placed, four claw portions 23 projecting from the pedestal portion 22 and fixing the jewel 21, and left and right side edges of the pedestal portion 22. left and right extending portions 24 extending outward in the left-right direction from the portion (side end portion);

The frame member 30 includes a frame body portion 31 disposed so as to surround the jewel 21 fixed to the hanger member 20 in a front view of the pendant top (accessory body) 10 , and left and right arms extending rearward from the frame body portion 31 . and left and right retaining ring portions 33 arranged at the distal end portions of the support arm portion 32 . Further, the frame member 30 is provided with a chain connecting portion 34 to which the chain 5 is connected, and a connecting portion 35 capable of connecting and coupling another decorative body to the frame member 30 .

In the frame member 30 of this embodiment, the frame main body portion 31, the left and right support arm portions 32, the left and right retaining ring portions 33, the chain connecting portion 34, and the connecting portion 35 are integrally formed. That is, the frame member 30 of the present embodiment is a single pressed product formed by pressing a single plate material (metal plate) made of a precious metal such as gold, platinum, or silver. made of material.

In the present disclosure, at least the frame main body portion 31, the left and right support arm portions 32, and the left and right retaining ring portions 33 of the frame member 30 need only be integrally formed, and the chain connecting portion 34 and the connecting portion 35 may be fixed to the frame main body 31 by, for example, brazing (welding) using a laser or the like.

The frame main body 31 has an annular or doughnut-like shape when the pendant top 10 is viewed from the front (FIG. 1). The frame body 31 surrounds the pedestal 22 of the hanger member 20 and the jewels (diamonds) 21 from the outside, and is spaced outward from the pedestal 22 and the jewels 21 . Therefore, a gap is formed between the frame body portion 31 and the pedestal portion 22 and the jewel 21 . In the present disclosure, if the frame main body 31 surrounds the pedestal 22 and the jewel 21 of the hanger member 20 from the outside and is spaced outward from the pedestal 22 and the jewel 21, for example, It may be formed in a frame shape other than an annular shape such as a rectangular frame shape.

The frame body portion 31 of this embodiment is formed with a constant thickness dimension. For example, in this embodiment, the thickness of the frame main body 31 is set to 0.15 mm or more and 0.35 mm or less. Further, the frame main body portion 31 has a substantially U-shaped or substantially J-shaped cross section perpendicular to the circumferential direction of the frame main body portion 31 along the entire circumference of the frame main body portion 31 . That is, in the frame main body 31, the center portion in the radial direction of the frame main body 31 is arranged on the frontmost side, and when the frame main body 31 is viewed from the rear side (not shown), the concave groove is formed. forming a circle. Further, in this embodiment, the inner peripheral portion 31a of the frame main body portion 31 is arranged on the front side of the outer peripheral portion 31b of the frame main body portion 31. As shown in FIG.

The left and right support arm portions 32 extend from the inner peripheral portion 31a of the annular frame main body portion 31 toward the direction (rearward) perpendicular to the circumferential direction of the frame main body portion 31. The frame body portion 31 and the retaining ring portion 33 are connected. By providing the left and right support arm portions 32 in this manner, the frame member 30 of the present embodiment can be stably manufactured using press working including shearing.

In this case, as will be described later, the support arm portion 32 is in a state immediately after the frame member 30 is manufactured by press working including shearing (see FIG. 3), from the frame main body portion 31 in the front-rear direction (in other words, It extends in a direction perpendicular to the thickness direction of the frame main body portion 31), and is further deformed (bent) after press working, so that the direction along the front-rear direction from the direction perpendicular to the front-rear direction. It is formed by being bent into

In this embodiment, the support arm portion 32 is formed with a constant thickness dimension from the frame body portion 31 to the retaining ring portion 33 . The thickness dimension of the support arm portion 32 is the same as the thickness dimension of the frame body portion 31 . Specifically, the thickness dimension of the support arm portion 32 is set to 0.15 mm or more and 0.35 mm or less. Since the thickness dimension of the support arm portion 32 is 0.15 mm or more, the appropriate strength of the support arm portion 32 can be stably ensured. Since the thickness dimension of the support arm portion 32 is 0.35 mm or less, the support arm portion 32 can be stably deformed in the deforming process after the press working described above. Also, the weight of the frame member 30 can be reduced.

The length dimension of the support arm portion 32 from the frame main body portion 31 to the retaining ring portion 33 is set larger than the thickness dimension of the supporting arm portion 32 and smaller than the inner diameter dimension Ri of the retaining ring portion 33. . Specifically, the length dimension of the support arm portion 32 is set to 0.10 mm or more and 0.50 mm or less.

Since the length dimension of the support arm portion 32 is 0.10 mm or more, only the support arm portion 32 can be stably deformed in the above-described deformation processing after press working. It is possible to prevent the annular shape of the retaining ring portion 33 from being distorted. Further, when the hanger member 20 swings with respect to the frame member 30 in the pendant top 10, the support arm portion 32 appropriately separates the frame main body portion 31 and the retaining ring portion 33, so that the hanger member 20 is It is possible to make it difficult for the swing ring portion 25 to contact (collide) with the frame main body portion 31, thereby making it easier to maintain the swinging motion of the hanger member 20 for a long time.

Further, since the length dimension of the support arm portion 32 is 0.50 mm or less, it is possible to prevent the position of the hanger member 20 from falling too far behind the frame member 30 . Thereby, the jewel 21 fixed to the hanger member 20 can be made large and easy to see from the front side of the pendant top 10.例文帳に追加Moreover, when the user wears the necklace 1, it is possible to prevent the hanger member 20 from coming into contact with the chest of the user. Note that the length dimension of the support arm portion 32 means that the support arm portion 32 supports from the end on the side where the support arm portion 32 connects to the frame main body portion 31 to the end on the side where the support arm portion 32 connects to the retaining ring portion 33 . It refers to the dimension of the shortest line segment along the arm portion 32 .

The width dimension of the support arm portion 32 is set larger than the length dimension of the support arm portion 32 and smaller than the outer diameter dimension Re of the retaining ring portion 33 . In the present disclosure, the width dimension of the support arm portion 32 refers to the dimension of the support arm portion 32 in the direction orthogonal to the thickness direction and the length direction. Specifically, the width dimension of the support arm portion 32 is set to 0.30 mm or more and 1.20 mm or less. By setting the width dimension of the support arm portion 32 to 0.30 mm or more, the appropriate strength of the support arm portion 32 can be stably ensured. Since the width dimension of the support arm portion 32 is 1.20 mm or less, the support arm portion 32 can be stably deformed in the above-described deformation processing after the press working. Also, the weight of the frame member 30 can be reduced.

In a front view of the frame member 30 from the front side ( FIG. 1 ), the left and right support arm portions 32 are arranged in the upper half portion (upper half portion) of the frame main body portion 31 . More specifically, for example, when the jewel 21 is placed in the center of the analog watch and the upward direction from the jewel 21 is the 12 o'clock direction, the right support arm portion 32 is positioned on the frame main body 31 in the 1 o'clock to 3 o'clock direction. The left support arm portion 32 is arranged within the range of the 9 o'clock to 11 o'clock direction of the frame body portion 31 . As a result, even if the left and right support arm portions 32 are provided on the inner peripheral portion 31a of the frame main body portion 31 so as to be manufactured by press working, when the hanger member 20 is suspended from the left and right retaining ring portions 33, , the jewel 21 fixed to the hanger member 20 can be stably arranged in the central portion of the ring-shaped frame body portion 31 when the pendant top 10 is viewed from the front.

The left and right retaining ring portions 33 are integrally provided at the distal end portion of the support arm portion 32 . Each retaining ring portion 33 is formed in an annular or ring shape. At the center of the retaining ring portion 33, a circular central portion is provided so that the swinging ring portion 25 of the hanger member 20 can be hooked on the inner peripheral portion of the retaining ring portion 33 along the left-right direction or substantially the left-right direction. An opening 33a is provided. In this case, the inner diameter Ri of the retaining ring portion 33 (that is, the diameter of the central opening 33a) is set to 0.40 mm or more and 1.00 mm or less. The outer diameter Re of the retaining ring portion 33 is set to 1.00 mm or more and 1.80 mm or less (see FIG. 3).

Each of the left and right holding ring portions 33 is provided with a slit 33b into which the swing ring portion 25 can be inserted before the holding ring portions 33 are connected (see FIG. 3). The holding ring portion 33 having such a slit 33b is plastically deformed by pressing the holding ring portion 33 so that the slit 33b disappears after a part of the rocking ring portion 25 is inserted inside the holding ring portion 33. As a result, the holding ring portion 33 is formed into a continuous ring shape capable of holding the rocking ring portion 25 so as not to come off from the holding ring portion 33 .

In each of the left and right retaining ring portions 33, the shape of the cross section orthogonal to the circumferential direction of the retaining ring portion 33 is, as shown in FIG. It has a tapered shape that tapers towards the edge. Such a tapered shape of the inner peripheral edge of the retaining ring portion 33 can be stably obtained by forming the retaining ring portion 33 by press working. Furthermore, by forming by press working, the strength of the retaining ring portion 33 can be increased compared to the conventional case of forming by lost wax casting, for example. In this embodiment, the maximum value of the thickness dimension (the dimension in the direction perpendicular to the circumferential direction and the radial direction) of the retaining ring portion 33 is preferably 0.15 mm or more and 0.35 mm or less. As a result, the retaining ring portion 33 can ensure adequate strength, stably support the hanger member 20 , and reduce the weight of the frame member 30 .

Further, in a front view of the frame member 30 (FIG. 1), the left and right holding ring portions 33 have a lower end portion 33c on which the swing ring portion 25 is hooked and an upper end portion 33d arranged on the opposite side of the lower end portion 33c. have In this case, the pair of left and right retaining ring portions 33 have a horizontal spacing between the upper ends 33d of the left and right retaining ring portions 33 that is larger than a horizontal spacing between the lower ends 33c of the left and right retaining ring portions 33. It is symmetrically arranged in a direction inclined with respect to the vertical direction so as to be narrow. In this case, it is preferable that the left and right retaining ring portions 33 are arranged at an angle of 20° or more with respect to the vertical direction, as shown in FIG. 1, for example.

As a result, even if the left and right support arm portions 32 are provided on the inner peripheral portion 31a of the frame body portion 31 in order to press the frame member 30, the distance between the lower end portions 33c of the left and right retaining ring portions 33 is increased. The hanger member 20 can be easily secured, and the hanger member 20 can be easily formed large (particularly, it can be easily formed large in the left-right direction). Therefore, it is possible to fix larger jewels 21 to the hanger member 20 with respect to the size of the frame member 30 . Therefore, the larger jewel 21 can be oscillated slightly with respect to the frame member 30 to make it shine beautifully.

The connecting portion 35 of the frame member 30 is provided at the lower end portion of the frame body portion 31 and is formed to protrude downward in an arc shape. By providing the connecting portion 35, various decorations such as a pendant top different from the pendant top 10 of the present embodiment, accessories, or a key holder with a logo mark can be placed under the frame member 30. It is possible to attach the body. As a result, it becomes possible to increase the variation of products and to use them for products in collaboration with other companies.

In the hanger member 20 of this embodiment, four claw portions 23 protrude outward from the outer peripheral edge portion of the base portion 22 in order to fix the jewel 21 thereon. Before the jewel 21 is placed on the pedestal 22, each claw 23 protrudes straight from the pedestal 22 as shown in FIG. In addition, after the jewel 21 is set on the pedestal 22 , each claw 23 is pressed toward the jewel 21 and plastically deformed into a bent shape, so that the jewel 21 is held by the pedestal 22 and the claw 23 . can be fixed.

The left and right extending portions 24 of the hanger member 20 are connecting portions that connect the pedestal portion 22 and the left and right swing ring portions 25 . The left and right extending portions 24 extend outward in the left-right direction from the base portion 22 and have symmetrical shapes. Such left and right extending portions 24 can change the length dimension between the pedestal portion 22 and the swing ring portion 25 according to the design of the pendant top 10 or the like. Also, in this embodiment, the hanger member 20 can be formed without providing the left and right extending portions 24 .

The left and right rocking ring portions 25 are integrally provided at the distal end portion of the extending portion 24 . Each rocking ring portion 25 is formed in an annular or ring shape, and a circular central opening 25a is provided at the center thereof. Further, each rocking ring portion 25 is supported by the extending portion 24 in a horizontal or substantially parallel orientation.

The left and right rocking ring portions 25 are hooked and held by the inner peripheral portions of the left and right holding ring portions 33 of the frame member 30 . In other words, the left and right rocking ring portions 25 and the left and right retaining ring portions 33 are engaged with each other by penetrating through the opposing central openings 25a and 33a and bringing the inner peripheral portions into contact with each other. .

In each of the left and right rocking ring portions 25, the shape of the cross section orthogonal to the circumferential direction of the rocking ring portion 25 is such that the tip portion on the inner peripheral side of the rocking ring portion 25 is pointed as shown in FIG. It has a tapered shape that tapers toward the inner peripheral edge. In addition, in this embodiment, the cross-sectional shape of the retaining ring portion 33 also has a tapered shape that gradually tapers toward its inner peripheral edge, as described above (see FIG. 4).

As a result, the swing ring portion 25 can be hooked on the inner peripheral portion of the holding ring portion 33 compared to the case where the cross section of the holding ring portion 33 and/or the swing ring portion 25 perpendicular to the circumferential direction is circular. When held, the contact area of the contact portion where the holding ring portion 33 and the swing ring portion 25 contact each other can be reduced. In particular, when the inner peripheral portion of the retaining ring portion 33 and the inner peripheral portion of the oscillating ring portion 25 are both formed to have sharp edge shapes as in this embodiment, the retaining ring portion 33 and the oscillating ring may be separated from each other. Since the portions 25 are in contact with each other at one point, the contact area can be made extremely small.

As a result, the support of the swing ring portion 25 by the retaining ring portion 33 is likely to become unstable, so that the hanger member 20 can be easily swung with respect to the frame member 30 . Furthermore, since the frictional resistance of the swinging ring portion 25 against the retaining ring portion 33 can be reduced, the hanger member 20 can be swung more finely, and the swinging motion of the hanger member 20 can be continued for a longer period of time. can.

In addition, the sharp tapered shape of the inner peripheral portions of the holding ring portion 33 and the swing ring portion 25 as described above is obtained by forming the holding ring portion 33 and the swing ring portion 25 by press working. can be stably obtained. Furthermore, by forming by press working, the strength of the retaining ring portion 33 and the swing ring portion 25 is increased compared to the case of forming by lost wax casting as in the related art. As a result, the inner peripheral edges of the retaining ring portion 33 and the swinging ring portion 25 can be formed thinner, so that the effect of making the hanger member 20 easier to swing and the effect of continuing the swinging action for a long time can be further enhanced. can.

In the hanger member 20 of this embodiment, when the left and right rocking ring portions 25 are hooked on the left and right holding ring portions 33, the central openings 25a provided in the left and right rocking ring portions 25 face in the front-rear direction. is held by the frame member 30. The hanger member 20 is formed so that the table surface of the jewel (diamond) 21 fixed to the hanger member 20 faces obliquely upward when the hanger member 20 is held by the frame member 30 (see FIG. 2). It is

Next, a method for manufacturing the pendant top 10 of the embodiment described above will be described.

The manufacturing method for manufacturing the pendant top 10 includes:
(i) a first press working step of producing a primary processed product 30a of the frame member 30 shown in FIG. 3 by press working a metal plate;
(ii) a bending step of bending the primary processed product 30a produced in the first pressing step so that the support arm portion 32 extends rearward from the frame main body portion 31;
(iii) a second press working step of producing the hanger member 20 shown in FIG. 5 by press working a thin flat metal plate;
(iv) a stone setting step of setting and fixing the jewel 21 to the pedestal portion 22 of the hanger member 20 produced in the second press working step;
(v) an assembling step of assembling the hanger member 20 to the frame member 30 to manufacture the pendant top 10;

The first press working step (i) includes a preparation step (A) for preparing a metal plate, a shearing step (B) for mechanically shearing (punching) the metal plate, the metal plate and A deformation step (C) of mechanically performing at least one of bending, drawing, and compression on at least one of the blank members punched from the metal plate. In the first press working step, the order of performing the shearing step (B) and the deforming step (C) is not limited, and either the shearing process or the deforming process may be performed first, and the shearing process and the deforming process may be performed first. can be alternated. In addition, performing shearing (or deforming) on at least one of the metal plate and the blank member formed from the metal plate means shearing (or deforming) the metal plate, forming from the metal plate At least one shearing (or deforming) of the shearing (or deforming) of the blank member and the shearing (or deforming) of both the metal plate and the blank member formed from the metal plate is performed. means that

In the preparation step (A), a thin flat metal plate is prepared as a work material. Although the thickness of the prepared metal plate is not particularly limited, it is preferably 0.2 mm or more, particularly 0.25 mm or more, in order to ensure appropriate strength in the frame member 30 produced by press working. In order to reduce the weight and cost of the frame member 30, the thickness of the metal plate is preferably 0.8 mm or less, particularly 0.5 mm or more.

The material (denomination) of the prepared metal plate is not particularly limited. As the material of the metal plate, for example, a metal selected from the group consisting of silver, gold, platinum, copper, and iron, an alloy of these metals (for example, an alloy containing at least one of silver and copper mainly composed of gold), and alloys containing these metals as the main component and other metals (for example, alloys containing gold as the main component and containing palladium or the like, alloys comprising copper as the main component and containing zinc, etc.), etc. may be employed. .

In the shearing step (B), the metal plate is sheared (for example, punched) to form a thin plate blank member. In this shearing step (B), the blank member may be formed by one shearing process, or the blank member may be formed by multiple shearing processes.

In the deformation step (C), the metal plate and/or the blank member punched from the metal plate is deformed (for example, drawn) so that the cross section orthogonal to the circumferential direction is substantially U-shaped or substantially U-shaped. At least a frame body portion 31 having a J shape is formed. In this deformation step (C), only one deformation process may be performed, or a plurality of deformation processes may be sequentially performed.

Here, an example of a method of manufacturing the primary processed product 30a of the frame member 30 shown in FIG. 3 from the prepared metal plate in the first press working step (i) will be briefly described. In addition, in the present disclosure, the method of manufacturing the primary processed product 30a is not limited to this.

First, the shape of the frame body portion 31 is formed in the metal plate by performing deformation processing (for example, drawing) on the metal plate. Subsequently, the metal plate on which the frame main body 31 is formed is sheared multiple times, so that left and right support arm portions 32 and left and right holding arms 32 as shown in FIG. The shape of the ring portion 33 is formed, and the shapes of the chain connecting portion 34 and the connecting portion 35 are formed outside the frame body portion 31 . After that, the metal plate on which the shape of each part is formed is subjected to shearing (for example, punching), and further, deformation processing is performed to bend the chain connecting portion 34, thereby producing the primary processed product 30a shown in FIG. do.

Next, the bending process (ii) is performed on the primary processed product 30a of FIG. In this bending process, a bending process is performed to bend the support arm portion 32 of the primary product 30a backward with respect to the frame main body portion 31 . Thus, the frame member 30 of this embodiment is produced. At this time, since the length dimension of the support arm portion 32 is larger than the thickness dimension of the support arm portion 32, the support arm portion 32 can be bent without distorting the retaining ring portion 33 when the support arm portion 32 is bent. The portion 32 can be smoothly bent backward. In addition, in the frame member 30 produced by this bending process, the left and right holding ring portions 33 are provided with slits 33b through which the rocking ring portion 25 of the hanger member 20 is inserted. Further, the above-described deformation processing for bending the chain connecting portion 34 may be performed in this bending process instead of the first press working process.

On the other hand, apart from the first pressing step (i), the second pressing step (iii) is performed to produce the hanger member 20 . The second press working step includes at least one of a preparation step of preparing a metal plate, a shearing step of shearing (punching) the metal plate, and a blank member punched from the metal plate. , and a deformation step of performing at least one of bending, drawing, and compressing. Also in this second press working step, the order of performing shearing and deforming is not limited, and either shearing or deforming may be performed first, and shearing and deforming may be performed alternately. may

For example, in the second press working step, the metal plate is deformed (for example, drawn) so that the contour of the pedestal portion 22, the shape of the claw portion 23, and the right and left extending portions 24 are formed on the metal plate. The shape forms the contours of the left and right oscillating ring portions 25 . Subsequently, by shearing the metal plate on which the frame body portion 31 is formed, the shape of the pedestal portion 22 and the left and right rocking ring portions 25 is formed in the metal plate. Thereafter, shearing (for example, punching) is performed on the metal plate in which the shapes of the pedestal portion 22, the claw portion 23, the left and right extending portions 24, and the left and right rocking ring portions 25 are formed, thereby obtaining the shape shown in FIG. The hanger member 20 shown is made.

After the second press working process is completed, the stone setting process (iv) is performed to set and fix the jewel 21 on the pedestal portion 22 of the hanger member 20 . In this stone fixing step, first, the jewel 21 is set on the pedestal portion 22 of the hanger member 20, and then the claw portion 23 of the hanger member 20 is pressed to cause plastic deformation, thereby fixing the jewel 21 to the pedestal portion 22. hold. Thus, the hanger member 20 to which the jewel 21 is fixed is produced.

After the frame member 30 and the hanger member 20 are produced, the assembly step (v) is performed to assemble the hanger member 20 to the frame member 30 . In this assembly process, the left and right rocking ring portions 25 of the hanger member 20 are inserted into the left and right retaining ring portions 33 through the slits 33b provided in the retaining ring portions 33 of the frame member 30, thereby allowing the left and right rocking portions 25 to swing. The moving ring portion 25 is hooked on the left and right holding ring portions 33 . As a result, the hanger member 20 is swingably suspended and held by the left and right holding ring portions 33 of the frame member 30 . After the hanger member 20 is hung on the left and right retaining ring portions 33, the retaining ring portions 33 are plastically deformed by pressing them so that the slits 33b disappear, thereby forming the retaining ring portions 33 into a ring shape.

The pendant top 10 of this embodiment is manufactured by performing the above steps. By passing the chain 5 through the chain connecting portion 34 of the pendant top 10, the necklace 1 in which the pendant top 10 is suspended from the chain 5 as shown in FIG. 1 is manufactured.

According to the necklace 1 and the pendant top 10 of this embodiment, the frame member 30 and the hanger member 20 are each formed of a single pressed product produced by pressing a single metal plate. there is Since the frame member 30 is formed of a press-worked product in this way, it takes less time to manufacture the frame member 30 and the pendant top 10 than the conventional frame member formed by lost-wax casting, for example. can be shortened, and the manufacturing cost of the frame member 30 can be reduced. Specifically, by producing the frame member 30 using press work as in the present embodiment, the production time of the frame member 30 can be reduced to 1/3 or less compared to the conventional case using lost wax casting. Also, the production cost of the frame member 30 can be reduced to 1/5 or less compared to the conventional case using lost wax casting.

In addition, since the frame member 30 is manufactured using press working as in the present embodiment, the frame member 30 can be mechanically manufactured without being easily affected by experience, skill, and the like. . As a result, it is possible to reduce the cost and time required for the training of producers, thereby further reducing the manufacturing cost. Furthermore, since the manufacturing of the pendant top 10 is less likely to be affected by the experience and skill of the workers, the occurrence of defective pendant tops 10 can be reduced. Moreover, the stability of the quality of the pendant top 10 can be ensured. Specifically, when a plurality of pendant tops 10 having the same structure are manufactured, the hanger member 20 is slightly swung with respect to the frame member 30 at the same speed and width in any of the pendant tops 10. Therefore, it is possible to easily achieve homogenization of the swinging motion (the way of swinging) of the hanger member 20, which has been difficult in the past.

Furthermore, by producing the frame member 30 using press work as in the present embodiment, the strength of the frame member 30 can be increased compared to the conventional case of using lost wax casting. It becomes possible to form the frame member 30 thinly. For example, even if the frame member 30 is thinly formed to have a thickness of 0.50 mm or less, or even a thickness of 0.35 mm or less, the frame member 30 can be stably formed into a desired shape. In addition, it is possible to stably secure an appropriate strength that can withstand use of the pendant top 10 . Furthermore, by forming the frame member 30 thin, it is possible to reduce the weight of the frame member 30 (for example, a weight reduction of about 50%), and the amount of raw metal used can be reduced, so that further cost reduction is possible. .

Moreover, by using press working, it is possible to mass-produce pendant tops 10 having the same structure, and to respond quickly to large demands. In addition, by using press working, the outer surface of the frame member 30 can be finely finished compared to the case of using lost wax casting, so that the appearance quality of the pendant top 10 can be further improved. Furthermore, when the frame member 30 is plated, the plated surface can be formed cleanly.

That is, according to the necklace 1 and the pendant top 10 of the present embodiment, in which the frame member 30 and the hanger member 20 are each formed of a single press-worked product, a product manufactured using lost wax casting or a frame Shorter manufacturing time, lower manufacturing costs, more stable quality, lighter weight, less defective products, and higher quality compared to products manufactured by fixing the retaining ring to the main body by brazing.
