Summary of the Invention

Problems to be Solved by the Invention

[0004] Patent Document 1 (the reference numerals are those of Patent Document 1) describes an ornament 25 (connected body ornament) in the form of a ring as a connected body ornament formed using a hollow rod member 2 (connecting part) (the reference numerals are the reference numerals of Patent Document 1). The ornament 25 (connected body ornament) is formed by connecting a hollow spherical decorative part 19 (hollow decorative part) having an opening 17 on one side (smaller diameter than the diameter of the flange 2b of the rod member 2) and an opening 18 on the other side (smaller diameter than the diameter of the flange 2b of the rod member 2) in such a manner that the flange 2b of the rod member 2 is inserted into the decorative part 19 (hollow decorative part).

[0005] The method for forming a jewelry item 25 (connected jewelry item) using rod members 2 (connecting parts) involves, for example, forming a group of rod members 3 (group of connecting parts) by passing the number of rod members 2 required to form a ring through a tension coil spring 6 (Figure 1 (a)), inserting one side of the flange portion 2b (protruding part) of one rod member 2 into the opening 17 on one side of the decorative member 19 with the lateral opening 16 opened to the width of the flange 2b, inserting the other side of the flange portion 2b (upper part of the flange) of the adjacent rod member 2 (connecting part) into the opening 18 on the other side of the decorative member 19, pressing down on the decorative member 19 to close the lateral opening 16, and connecting the rod members.

[0006] The technology described in Patent Document 1 has the drawbacks that, in order to close the horizontal opening 16 and make the decorative member 19 spherical, the closed horizontal opening 16 becomes a visible seam, resulting in poor aesthetics and a low-quality image, and there is a risk that the horizontal opening 16 may shift or open up.

[0007] In view of the aforementioned shortcomings of the prior art, the present invention aims to provide a connecting component for decorative items that makes it possible to connect seamless hollow decorative members, each having a hollow structure with openings on both sides, one by one. Furthermore, the objective is to provide a connected type of ornament (e.g., a ring, a bracelet) in which the seamless hollow decorative members are connected by the connecting parts for ornaments, and a tensile biasing member such as a tension coil spring is passed through the connecting parts for ornaments, thereby causing the ring, which is formed in a ring shape, to expand in diameter due to the biasing force. [Means for solving the problem]

[Modes for carrying out the invention]

[0011] The following describes embodiments that represent the best mode for carrying out the present invention. However, the present invention is not intended to be limited to these embodiments only. Furthermore, in describing the embodiments described later, the same reference numerals are used for the same components as in the embodiments described above, and redundant explanations are omitted. [Examples]

[0012] In Embodiment 1 of the present invention shown in Figures 1 to 4, the connecting part 1 has one side opening 3a on one side of the decorative part body 2 and the other side opening 3b on the other side of the decorative part body 2, and is a connecting part for a seamless hollow decorative part 4 in which the decorative part body 2 is a seamless hollow body, and has the following configuration.

[0013] The connecting component body 5 has a rod-shaped form with a through hole 9 that penetrates in the axial direction (a form with a through hole that penetrates from one side of the protruding portion 7a to the other side of the protruding portion 7b), A flange-shaped projection 7a is provided on one side of the main body 5 of this connecting component, with a helical portion 6a (for example, a screw) threaded onto it. The connecting component body 5 is provided with a flange-like projection on the other side, which has a spiral portion 6b (for example, a screw) threaded onto it, and the other side projection 7b is provided in a flange-like shape that protrudes outward from the main body of the connecting component. The diameter of the projection 7a on one side is larger than the diameter of the opening 3b on the other side. The diameter of the other side projection 7b is larger than the diameter of the opening 3a on the other side. When the spiral portion 6b of the other side projection 7b is placed against the opening 3a on one side and the connecting component body 5 or the seamless hollow decorative component 4 is rotated, the spiral portion 6b screws into the opening 3a on the one side and proceeds, so that the entire other side projection 7b enters the connecting component body 5. When the helical portion 6a of the protruding portion 7a on one side is placed against the opening 3b on the other side and the connecting component body 5 or the seamless hollow decorative component 4 is rotated, the helical portion 6a screws into the opening 3b on the other side and proceeds, so that the entire protruding portion 7a on one side enters the connecting component body 5. The connecting component is characterized in that the diameters of the one-sided protrusion 7a and the other-sided protrusion 7b, which are located inside the main body 5 of the connecting component, are larger than the diameter of the other-sided opening 3b and the diameter of the one-sided opening 3a, so that they come into contact with the inner wall of the one-sided opening 3a and the inner wall of the other-sided opening 3b, thereby forming a connecting configuration that prevents them from coming loose.

[0014] The detachment-preventing connection configuration is such that the back wall surface of one side projection 7a forms a contact surface 8a, and this contact surface 8a contacts the inner wall of the other side opening 3b, thereby forming the detachment-preventing connection configuration.

[0015] The helical portions 6a and 6b should preferably be threaded, and the tip should be a small-diameter gripping portion or designed to function as a gripping portion. The pitch of the helical portions 6a and 6b should be at least 1 pitch and within 1.5 pitches, preferably 1.5 pitches and within 2 pitches, but it may also be greater than that. In this embodiment, the helical portions 6a and 6b are M1.7 male threads.

[0016] The diameter of the valley bottom formed by the spiral valley bottom portions of the spiral sections 6a and 6b is the same as or smaller than the diameter of the protruding portion 7a on one side and the protruding portion 7b on the other side, while the diameter of the peak formed by the spiral peak portions of the spiral sections 6a and 6b is larger than the diameter of the protruding portion 7a on one side and the protruding portion 7b on the other side.

[0017] The seamless hollow decorative part 4 and the connecting part body 5 are generally made of precious metals such as gold, platinum, silver, and titanium, but other materials such as plastic may also be used.

[0018] The groove width tH of the spiral portion 6a of the protruding portion 7a on one side and the spiral portion 6b of the protruding portion 7b on the other side are wider than the thickness of the rim of the opening 3b on the other side and the rim of the opening 3a on one side of the seamless hollow decorative part 4 (the rim is thinner than the groove width tH). Forms in which the rim is thinner than the valley width tH include, for example, forms in which the rim slopes from the outside to the inside or from the inside to the outside, and in such forms, forms in which a portion of the thickness of the rim is thinner than the valley width tH are also included in the technical scope.

[0019] <Formation of linked ornamental item 11> In Figures 2, 3, and 4, Multiple connecting parts 1, Multiple seamless hollow decorative parts 4, It has a tensile biasing member 10 (for example, a tension coil spring, a rubber string), In this configuration, a tension biasing member 10 is passed through the through-hole 9 of the connecting component 1 and from one side opening 3a to the other side opening 3b of the seamless hollow decorative component 4. Multiple connecting components 1 and multiple seamless hollow decorative components 4 are alternately set on the tension biasing member 10, and the connecting components 1 are connected in a way that prevents them from coming loose from the seamless hollow decorative components 4, forming a connected type of ornament 11 in the shape of a ring (for example, a ring or bracelet).

[0020] The seamless hollow decorative component 4 can have a variety of shapes and forms (polygons, ellipsoids, cones, cylinders), and forms with ornaments such as gemstones (e.g., diamonds, rubies, pearls, etc.) are also included within the technical scope. While precious metals such as gold, platinum, silver, and titanium are common materials for the seamless hollow decorative component 4, the technical scope also includes a variety of other materials such as other metals (e.g., stainless steel, medical-grade stainless steel), plastic components, wooden components, plated components, and painted components. Furthermore, the shape and form of the seamless hollow decorative parts 4 that make up one connected ornament 11 may not be of the same type, but may be of different shapes and forms used in the connected ornament 11.

[0021] <Formation of linked ornamental item 11> The formation of the linked ornament 11 is as follows: (1) One tension biasing member 10 is set in one connecting part 1 (in which case the tension biasing member 10 is passed through the through hole 9 of the connecting part 1), Next, the seamless hollow decorative part 4 is set on the tension biasing member 10 (in a configuration where the tension biasing member 10 is passed from the opening of the seamless hollow decorative part 4 to the opposite opening), The spiral portion 6b of the other-side projection 7b is placed against the opening 3a on one side, and the connecting component body 5 or the seamless hollow decorative component 4 is rotated to screw the spiral portion 6b into the opening 3a on the one side, thereby creating a detachment-preventing connection form in which the other-side projection 7b has passed through the opening 3a on the one side, that is, the entire projection 7b is inside the connecting component body 5 (see Figure 2). Set the next connecting component 1 onto the tension biasing member 10, The helical portion 6a of the one-sided projection 7a of the connecting part 1 is placed against the other-sided opening 3b, and the connecting part body 5 or the seamless hollow decorative part 4 is rotated to screw the helical portion 6a into the other-sided opening 3b, thereby creating a detachment-preventing connection form in which the one-sided projection 7a has passed through the other-sided opening 3b, that is, the entire projection is inside the connecting part body 5. The above operations are performed one by one, alternating between setting the required number of connecting parts 1 and the required number of seamless hollow decorative parts 4. Finally, both ends of the tension biasing member 10 are connected (connecting portion), and the connecting portion is placed inside the seamless hollow decorative part 4 to form a ring-shaped connected ornament 11. (2) Alternatively, the required number of connecting parts 1 and the required number of seamless hollow decorative parts 4 may be set alternately on a single tension biasing member 10, and the connecting operation and connecting process described in (1) above may be performed.

[0022] The connection operation between connecting part 1 and seamless hollow decorative part 4 can be performed manually without the use of any jigs.

[0024] In Embodiment 2 of the present invention shown in Figures 5 to 7, the connecting part 20 is a connecting part for decorative items that connects the seamless hollow decorative parts 4, and has the following configuration.

[0025] A connecting part 20 that connects hollow decorative parts, having one side opening 3a on one side of the decorative part body 2 and the other side opening 3b on the other side of the decorative part body 2, wherein the decorative part body 2 is a hollow body, A connecting component body 22 having a rod-shaped form and a through hole 27 that penetrates axially, A one-sided protruding portion 25a is provided on one side of the connecting component body 22, protruding outward from the connecting component body 22, with its back wall surface acting as a contact surface 23a, and a one-sided biasing movable claw 26a is made biasable and movable in approximately the vertical direction Ld if the axial direction of the connecting component body 22 is considered to be the horizontal direction, The connecting component body 22 has a connecting component body body 22 on the other side, which has a connecting component body body 22 with a connecting component body body 22 that protrudes outward and has its back wall surface as a contact surface 23b, and a connecting component body body 22 has a connecting component body body 26b that is biased and movable in a substantially vertical direction Ld if the axial direction of the connecting component body body 22 is the horizontal direction, The biasing movable claw 26a on one side is designed to move inward (approximately in the vertical direction Ld) when pushed into the other side opening 3b, and to move outward and return to its original position after passing through the other side opening 3b. The other-side biasing movable claw 26b is configured to move inward (moves approximately in the vertical direction Ld) when pushed into the one-side opening 3a, and to move outward with biasing force once it has passed through the one-side opening 3a, and to return to its original position. The connection is characterized in that the contact surface 23a of the biasing movable claw 26a on one side, which is inside the connecting component body 22, contacts the inner wall surface of the other side opening 3b, and the contact surface 23b of the biasing movable claw 26b on the other side, which is inside the connecting component body 22, contacts the inner wall surface of the one side opening 3a, thereby forming a disconnection-preventing connection configuration that prevents disconnection.

[0026] The biasing movable part of the biasing movable claw 26a on one side, other than the base, is separated by separation parts 27a and 27b formed on the connecting part body 22. In this configuration, all or part of the biasing movable portion of the other biasing movable claw 26b, excluding its base, is separated by separation portions 27a and 27b formed on the connecting component body 22. With this configuration, the biasing movable claw 26a on one side and the biasing movable claw 26b on the other side are long, making them easier to move with a weak pushing force in the vertical direction Ld, and allowing them to pass through the edges of the openings 3a on one side and 3b on the other side without deformation, or with only slight deformation.

[0027] In this embodiment, the biasing movable claws are provided in two locations on one side and two locations on the other side, but the number and arrangement of the biasing movable claws may be one or two or more.

[0028] <Formation of linked ornamental item 30> (1) Set one of the connecting parts 20 onto one of the tension biasing members 10 (in a form in which the tension biasing member 10 is passed through the through hole 9 of the connecting part 20), Next, one of the seamless hollow decorative parts 4 is set onto the tension biasing member 10 (in a configuration where the tension biasing member 10 is passed from the opening of the seamless hollow decorative part 4 to the opposite opening), The other-side biasing movable claw 26b is brought into contact with the one-side opening 3a and the connecting component body 22 or the seamless hollow decorative component 4 is pushed (including the operation of pushing both), causing the other-side biasing movable claw 26b to enter the one-side opening 3a, and creating a disconnection-preventing connection form in which the other-side biasing movable claw 26b has passed through the one-side opening 3a, that is, in a state in which the entire claw is inside the connecting component body 22 (see Figure 6). Set one of the following connecting parts 20 onto one of the tension biasing members 10. Next, one of the seamless hollow decorative parts 4 is set onto the tension biasing member 10. The biasing movable claw 26a on one side is brought into contact with the opening 3b on the other side and the connecting component body 22 or the seamless hollow decorative component 4 is pushed (including the operation of pushing both) to move the biasing movable claw 26a on one side into the opening 3b on the other side, thereby creating a disconnection-preventing connection form in which the biasing movable claw 26a on one side has passed through the opening 3b on the other side, that is, in a state in which the entire claw is inside the connecting component body 22. The above operations are performed one by one, alternating between setting the required number of connecting parts 2 and the required number of seamless hollow decorative parts 4. Finally, both ends of the tension biasing member 10 are connected (connecting portion), and the connecting portion is placed inside the seamless hollow decorative part 4 to form a ring-shaped connected ornament 30.
