[0006] Patent Document 1: Japanese Patent Publication No. 2021-514273 Summary of the Invention

[0007] The problem the invention aims to solve

[0008] In the chain-link type jewelry described in Patent Document 1, since the first through hole is located in a different position from the setting, the pin can be seen from the outside, which presents a decorative problem.

[0009] The problem to be solved by the present invention is to provide a link-connected jewelry piece in which the pins used to connect the links are not visible from the outside, thus having a high degree of decorative appeal.

[0010] Solution for solving the problem

[0011] The jewelry of the present invention, completed to solve the above-mentioned problems, is formed by connecting multiple links, each of which has: a ring-shaped body; a plurality of settings provided on the outer periphery of the body for mounting decorative elements; a first through hole provided in one of the plurality of settings and extending radially through the body; and an extension portion erected on the body in a manner spanning the central space of the body, having a second through hole at its front end. The jewelry includes a pin that passes through the first through hole of each link and the second through hole of the extension portion of an adjacent link inserted into the central space of the body of that link.

[0012] In addition to decorative elements made of natural minerals such as diamond, ruby, and sapphire, the decorative elements in this invention also include decorative elements derived from organisms such as pearl and coral, as well as artificially made decorative elements such as synthetic diamonds.

[0013] In this invention, the first through hole can also be provided in two inserts located in the space between the center of the main body. Alternatively, only one first through hole can be provided, and a non-through hole (non-through hole) can be provided on the inner periphery of the main body on the side opposite to the first through hole in the inner space of the ring between the main body. When two first through holes are provided, the pin passes through both the first through holes and the second through hole. When one first through hole and one non-through hole are provided, the pin passes through one first through hole and the second through hole, and its front end is inserted into the non-through hole.

[0014] In the jewelry of the present invention, based on the insertion of the extension of the adjacent chain link into the central space of each chain link, the positions of the first through hole provided in the setting and the second through hole of the adjacent chain link are aligned, and a pin is passed through these first through holes and second through holes, thereby connecting the adjacent chain links to each other. Decorative elements are mounted on each setting including the setting provided with the first through hole.

[0015] According to the present invention, by providing a first through hole in the mounting base, a pin passing through the first through hole can be hidden using decorative elements, thereby improving the decorative effect.

[0016] In the jewelry of the present invention, it is preferable that the inner diameter of the second through hole is larger than the outer diameter of the pin. This increases the freedom of movement of each link relative to adjacent links, or allows the jewelry to bend by using the joint between two adjacent links. Therefore, it can be appropriately used for chain-like jewelry such as bracelets and necklaces that require bending. Furthermore, when inserting the pin through the first and second through holes, the second through hole is hidden by the main body and therefore difficult to observe visually; however, by making the diameter of the second through hole larger than the diameter of the pin 3, the operation becomes easier.

[0017] Furthermore, it is preferable that, in each of the plurality of links, the mounts are arranged at equal intervals in the circumferential direction of the body. By arranging the links such that the circumferential position of the mounts is offset from each other by an amount of 1 / 2 interval between adjacent links, it is possible to prevent the mounts from colliding with each other between adjacent links, thereby increasing the vertical size of the decorative element mounted on the mount.

[0018] Preferably, when the inserts in each of the plurality of links are arranged at equal intervals in the circumferential direction of the body, the number of inserts is (4n+2) (n is a natural number), and the first through hole and the second through hole extend in directions 90° apart from each other. Thus, when a pin is passed through the first through hole and the second through hole, adjacent links are connected with the inserts offset from each other by 1 / 2 interval in the circumferential position, preventing the inserts from colliding with each other between adjacent links as described above.

[0019] The effects of the invention

[0020] According to the present invention, a link-connected jewelry can be obtained in which the pins used to connect the links are not visible from the outside, thus making it highly decorative. Attached Figure Description

[0031] use Figures 1-10 The embodiments of the jewelry ornaments of the present invention will be described.

[0032] (1) First implementation method

[0033] Figure 1 The left image shows the overall structure of the jewelry 1 according to the first embodiment, and the right image is an enlarged view of a part of the jewelry 1. The jewelry 1 is formed by alternately connecting the first link 10A and the second link 10B.

[0034] use Figure 2 (a) 3D diagram Figure 3 (a) Top view and Figure 4 The cross-sectional views (a-1) to (a-3) show the structure of the first link 10A. Here, Figure 4 (a-1), (a-2), and (a-3) are respectively... Figure 3 The sections A1-A1, A2-A2, and A3-A3 are shown in (a). Section A1-A1 is parallel to the plate surface of extension 14A, which will be described later. Section A2-A2 is perpendicular to section A1-A1. Section A3-A3 is the section obtained by rotating section A1-A1 to the right (clockwise) by (360 / 16)° = 22.5° from top view.

[0035] The first link 10A has an annular body 11, eight inserts 12 provided on the outer periphery of the body 11, and an extension 14A erected on the body 11.

[0036] Eight mounting bases 12 are arranged at equal intervals of 45°. Each mounting base 12 has four prongs: an upper prong 121 at the top, a lower prong 122 at the bottom, and two side prongs 123 on both sides. Decorative elements 18 are secured by these four prongs. The decorative elements 18 can be made of natural minerals such as diamond, ruby, and sapphire; derived from organisms such as pearl and coral; or artificially made elements such as synthetic diamonds. Furthermore, each side prong 123 is shared by two adjacent mounting bases 12. Therefore, the first link 10A has eight components of side prongs 123.

[0037] Two of the eight mounting bases 12, separated by a central space 111 in the main body 11, are provided with a first through hole 13 that radially penetrates the main body 11 and has a circular cross-section. The first through hole 13 extends parallel to the A3-A3 cross-section. Alternatively, one of the two first through holes 13 may be replaced with a non-through hole that forms its bottom midway from the inside of the main body 11 toward the outer periphery.

[0038] A pin retaining tube 131, formed by a tubular component, is provided in the central space 111 of the main body 11 and communicates with the first through hole 13.

[0039] The extension 14A is formed by a plate-shaped member erected on the main body 11 in a manner that spans the central space 111 of the main body 11. The plate surface of the extension 14A is parallel to the A1-A1 section and offset by 22.5° relative to the direction of extension of the first through hole 13 (see reference). Figure 3 (a) Furthermore, a second through hole 15A with a circular cross-section is provided in the extension 14A, which is perpendicular to the plate surface (parallel to section A2-A2). Therefore, the direction in which the second through hole 15A extends is offset from the direction in which the first through hole 13 extends in the first link 10A by (90-22.5)° = 67.5°. Additionally, a notch 16A is provided in the lower part of the plate surface of the extension 14A (the part near the main body 11).

[0040] use Figure 2 (b) 3D diagram Figure 3 (b) Top view and Figure 4 The cross-sectional views (b-1) to (b-3) show the structure of the second link 10B. Here, Figure 4 (b-1), (b-2), and (b-3) are respectively... Figure 3 The sections B1-B1, B2-B2, and B3-B3 are shown in (b). As described later, sections B1-B1, B2-B2, and B3-B3 are parallel to sections A1-A1, A2-A2, and A3-A3, respectively, when the first link 10A and the second link 10B are connected.

[0041] The second link 10B has a body 11, eight inserts 12, and an extension 14B. The structure of the body 11 and the inserts 12 is the same as that of the first link 10A.

[0042] The extension 14B is formed by a plate-shaped member erected on the main body 11, spanning a central space 111. It has a notch 16B at its lower part, similar to the extension 14A of the first link 10A. The plate surface of the extension 14B is parallel to the B2-B2 section and extends in the same direction as the first through hole 13. A second through hole 15B with a circular cross-section is provided in the extension 14B. This second through hole 15B extends in a direction inclined at 22.5° relative to the direction parallel to the B3-B3 section and perpendicular to the plate surface. The direction of extension of the second through hole 15B in the second link 10B is offset by (90-22.5)° = 67.5° from the direction of extension of the first through hole 13.

[0043] Both the first link 10A and the second link 10B are made of metal. To enhance the decorative effect of the jewelry 1, precious metals such as silver and platinum are preferred.

[0044] The jewelry ornament 1 of the first embodiment also has a pin 17. The pin 17 is a cylindrical member with an outer diameter approximately equal to the inner diameter of the first through hole 13. The inner diameters of the second through holes 15A and 15B are larger than the outer diameter of the pin 17.

[0045] As described below, the jewelry 1 of the first embodiment is assembled by connecting the first link 10A and the second link 10B with pins 17.

[0046] exist Figure 5In the diagram, the A2-A2 section of the first link 10A and the B2-B2 section of the second link 10B are used to represent the state where the second link 10B is connected above the first link 10A. These A2-A2 and B2-B2 sections are identical when the first link 10A and the second link 10B are connected. During the connection operation, firstly, the extension 14A of the first link 10A is inserted into the space 111 of the body 11 of the second link 10B, and the plate surface of the extension 14A is perpendicular to the plate surface of the extension 14B of the second link 10B, so that the front end of the extension 14A of the first link 10A is embedded in the notch 16B of the second link 10B. In this state, the two first through holes 13 of the second link 10B are aligned with the second through hole 15A of the first link 10A, and the pin 17 is passed through the two first through holes 13, the pin retaining tube 131 communicating with them, and the second through hole 15A. Alternatively, if one first through hole and one non-through hole are used instead of two first through holes 13, the tip of the pin 17 is inserted into the non-through hole through the second through hole 15A from the first through hole. After the pin 17 is passed through each through hole, decorative elements 18 are fixed to the two inserts 12 of the second link 10B, where the first through holes 13 are provided, so that the pin 17 will not come out of the through holes, and the first link 10A and the second link 10B are connected. Decorative elements 18 are also fixed to the other six inserts 12 of the second link 10B.

[0047] exist Figure 6 and Figure 7 In the middle, the A3-A3 section of the first link 10A and the B3-B3 section of the second link 10B are used ( Figure 6 ), and the A1-A1 section of the first link 10A and the B1-B1 section of the second link 10B ( Figure 7This indicates that the first link 10A is connected above the second link 10B. Sections A3-A3 and B3-B3, as well as sections A1-A1 and B1-B1, become identical when the first link 10A and the second link 10B are connected. During the connection operation, the extension 14B of the second link 10B is inserted into the space 111 of the body 11 of the first link 10A, with the plate surface of the extension 14B perpendicular to the plate surface of the extension 14A of the first link 10A, and the front end of the extension 14B of the second link 10B is embedded in the notch 16A of the first link 10A. Furthermore, the two first through holes 13 of the first link 10A are aligned with the second through hole 15B of the second link 10B, and a pin 17 is inserted through the two first through holes 13, the two pin retaining tubes 131, and the second through hole 15B. Subsequently, decorative elements 18 are fixed to the two inserts 12 of the first link 10A, which has a first through hole 13, thereby connecting the first link 10A and the second link 10B. Decorative elements 18 are also fixed to the other six inserts 12 of the first link 10A.

[0048] By repeatedly performing the aforementioned operation of connecting the second link 10B above the first link 10A and connecting the first link 10A above the second link 10B, a jewelry ornament 1 of the first embodiment in which multiple first links 10A and second links 10B are alternately connected is obtained.

[0049] According to the jewelry 1 of the first embodiment, by providing the first through holes 13 of the first link 10A and the second link 10B respectively in the setting, the pin 17 passing through the first through hole 13 can be hidden by the decorative element 18. As a result, the decorativeness of the jewelry 1 can be improved.

[0050] In the first embodiment of the jewelry 1, since the inner diameter of the second through holes 15A and 15B is larger than the outer diameter of the pin 17, a gap is created between the edges of the second through holes 15A and 15B and the side of the pin 17. This gap increases the degree of freedom for the jewelry 1 to bend by moving the links relatively up and down (in the direction in which the multiple first links 10A and second links 10B are arranged) or by using the first links 10A and second links 10B as joints when the first links 10A and second links 10B are connected by the pin 17. Therefore, the jewelry 1 of the first embodiment can be appropriately used as a chain-like jewelry such as a bracelet or necklace that requires bending. Furthermore, while the second through holes 15A and 15B are hidden by the main body 11 and difficult to observe visually when the pin 17 is being inserted, the operation becomes easier by making the diameter of the second through holes 15A and 15B larger than the diameter of the pin 17.

[0051] In the jewelry 1 of the first embodiment, in each of the first links 10A and the second links 10B, the setting 12 is arranged at equal intervals in the circumferential direction, and between adjacent first links 10A and second links 10B, the circumferential position of the setting 12 is offset by half of the interval (see reference). Figure 3 (a) and (b)). Thus, even if the mounting base 12 is increased in the vertical direction, the mounting base 12 will not collide with each other between adjacent first link 10A and second link 10B, thereby increasing the size of the decorative element 18 mounted on the mounting base 12.

[0052] (2) Second Implementation

[0053] use Figures 8-10 The jewelry according to the second embodiment will be described. In the second embodiment, only one type of link 10C is used. The link 10C has a main body 11, six settings 12, and an extension 14C. The main body 11 is the same as the main body in the first embodiment. The six settings 12 are equally spaced around the circumference of the main body 11, and two of them, separated by a central space 111 of the main body 11, are provided with the same first through hole 13 and pin retainer tube 131 as in the above embodiment. The extension 14C, like the extension 14A in the above embodiment, is formed by a plate-shaped member erected on the main body 11 such that it spans the central space 111 of the main body 11, and a second through hole 15C is provided perpendicular to the plate surface, and a notch 16C is provided at the lower part of the plate surface. The first through hole 13 and the second through hole 15C extend in directions that are 90° apart from each other.

[0054] In the jewelry of the second embodiment, the links 10C are connected to each other as follows. First, the extension 14C of one link 10C is inserted into the space 111 of the body 11 of the adjacent link 10C, and the front end of the extension 14C is embedded in the notch 16C of the adjacent link 10C. In this state, the pin 17 is passed through the first through hole 13, the pin retaining tube 131, and the second through hole 15C. Then, by fixing decorative elements 18 to the two settings 12 provided with the first through hole 13, the pin 17 will not come out of the through holes, and the two links 10C are connected. Decorative elements 18 are also fixed to the other four settings 12 of each link 10C. By repeating the above operation, multiple links 10C are connected to obtain the jewelry of the second embodiment.

[0055] According to the jewelry of the second embodiment, by connecting the links 10C, each with six sets 12 arranged at equal intervals, with their orientation changing by 90° in the circumferential direction each time, the sets 12 are arranged circumferentially offset by half the interval between adjacent links 10C, thereby preventing the sets 12 from colliding with each other between adjacent links 10C. Furthermore, by connecting the links 10C with their orientation changing by 90° in the circumferential direction each time, the first through hole 13 extends in the same direction as the second through hole 15C of the adjacent link 10C, allowing the pin 17 to be easily passed through these through holes. Moreover, the jewelry of the second embodiment achieves the same effect as the jewelry of the first embodiment 1.

[0056] (3) Variations

[0057] The present invention is not limited to the above-described embodiments and can be modified in various ways.

[0058] For example, the number of settings on each link is set to 8 or 6 in the two embodiments described above, but it is not limited to these examples; at least two are sufficient. In order to achieve the same effect as the jewelry of the second embodiment by connecting links with the same structure by changing their orientation by 90° each time in the circumferential direction, the number of settings on each link can be set to 10 or 14, or (4n+2) (where n is a natural number).

[0059] In the above embodiment, the setting 12 is arranged at equal intervals around the circumference of the main body 11, but the setting can also be arranged at non-equal intervals. For example, the setting 12 may not be provided in the area that is in direct contact with the skin when a person wears jewelry or in the area that is not visually visible from the outside.

[0060] In the above embodiment, a pin retaining tube 131 communicating with the first through hole 13 is provided in the space 111 in the center of the main body 11, but the pin retaining tube 131 may be omitted.

[0061] In the above embodiment, the extension 14A of the first link 10A and the extension 14B of the second link 10B are connected with their plate surfaces perpendicular to each other, but the orientation of the extensions is not limited to this. For example, if only the second link 10B in the above embodiment is used, and the plate surfaces of the extensions 14B of adjacent second links 10B are intersected at (90°-22.5°) = 67.5° (here, "45°" is half of the period of the mounting base 12 in the main body 11), then the extension directions of the first through hole 13 and the second through hole 15B of the adjacent second link 10B are consistent, and the second links 10B can be connected to each other using the pin 17. In addition, in this case, the notch 16B of the second link 10B is formed to match the direction in which the plate surfaces of the extensions 14B intersect each other, and is inclined at 22.5° from the direction perpendicular to the plate surface.

[0062] In the above embodiment, notches 16A-16C are provided at the lower part of the plate surface of the extensions 14A-14C. However, for example, if the thickness of the main body is sufficiently thick compared to the diameter of the second through hole, or if the upper end of the extension does not reach the lower end of the extension of the adjacent link when the links are connected to each other, the notches may be omitted.

[0063] In addition, the shape of the extension is not limited to plate-like; it can also be cylindrical or prismatic, etc.

[0064] In the above embodiment, a mounting base 12 with claws is used, but the structure of the mounting base is not limited to this. For example, a structure in which decorative elements are fixed in a through hole or a non-through hole provided on the outer periphery of the main body can also be used. When the mounting base 12 is a structure that fixes the decorative element to the through hole, one of the through holes or two opposite each other across the space 111 can be used as the first through hole, i.e., the through hole through which the pin 17 passes. In this case, by pre-fixing the pin to the decorative element, the operation of passing the pin through the first through hole and the second through hole and the operation of fixing the decorative element to the mounting base can be performed simultaneously.

[0065] In the above embodiment, the inner diameter of the second through holes 15A-15C is made larger than the outer diameter of the pin 17 to create a gap between the edge of the second through holes 15A-15C and the side of the pin 17. However, if it is desired to securely fix adjacent links to each other, the inner diameter of the second through holes 15A-15C and the outer diameter of the pin 17 can be made to be approximately the same diameter (within the range that allows the pin 17 to pass through the second through holes 15A-15C).
