Description

[Technical field]

[0001] The present invention relates to an expandable ring-shaped jewelry, in particular a bracelet, necklace or anklet. [Background technology]

[0002] When attaching a conventional bracelet to the wrist, the clasps attached to both ends of the chain-like body are placed behind the wrist, and the bracelet is attached and removed. Moreover, the bracelet must be removed with one hand, which is extremely inconvenient.

[0003] To solve this problem, a configuration disclosed in Japanese Patent No. 7329291 includes an expandable linear body and an ornamental body interposed between one end and the other end of the linear body, the linear body having a plurality of first hollow members each having two first openings, a plurality of second hollow members each having two second openings, and a linear elastic member, the first hollow members and the second hollow members are alternately arranged and connected to form a hollow member row, and each of the second hollow members is slidably inserted into the first openings of two of the first hollow members adjacent to each other on both sides in the hollow member row. the elastic member is inserted into each of the second openings of each of the second hollow members in the row of hollow members, and anti-slip portions are provided at both ends of the elastic member to prevent the elastic member from passing through the second hollow member, and at least one of the two anti-slip portions provided at both ends of the elastic member is an expandable ring-shaped ornament that is an expanded diameter portion of the elastic member.

[0004] However, the expandable ring-shaped ornament disclosed in the above publication includes a decorative body interposed between one end and the other end of the linear body, and the elastic member is inserted into each of the second openings of each of the second hollow members in the row of hollow members, and both ends of the elastic member are provided with anti-slip portions that prevent the elastic member from passing through the second hollow member, and at least one of the two anti-slip portions provided on both ends of the elastic member consists of an expanded portion of the elastic member, which makes it difficult to process the expanded portion of the elastic member and makes assembly work time-consuming, which is troublesome.

[0005] [Patent Document 1] Patent No. 7329291 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in consideration of the above-mentioned situation, and aims to provide an expandable ring-shaped ornament that is simple and aesthetically pleasing, without the need for an ornamental body interposed between one end of the linear body and the other end. [Means for solving the problem]

[0007] The expandable ring-shaped ornament proposed by this school is characterized in that multiple box-shaped decorative bodies, each with an opening at one end, are set side by side facing in one direction, a tubular connecting part having a stop frame at one end which engages with the side wall of the opening is inserted into the opening to engage the stop frame with the side wall of the opening, and a coil-shaped connecting spring is inserted inside the tubular connecting part, thereby connecting the multiple box-shaped decorative bodies to make them expandable and contractible.

[0008] Another feature of this invention is that the box-shaped decorative bodies, each with an opening facing in the one direction, have a spherical appearance overall with a seat formed on the back surface, and multiple box-shaped decorative bodies, each with a spherical appearance with a seat formed on the back surface, are connected via a tubular connecting part.

[0009] Furthermore, the box-shaped decorative bodies each have an opening inside facing the one direction, and overall have a spherical appearance with a seat formed on the back surface, and a decorative body is attached to the front of multiple box-shaped decorative bodies each having a spherical appearance with a seat formed on the back surface. Effect of the Invention

[0010] The present invention is constructed as described above, and can provide an expandable ring-shaped jewelry that is easy to manufacture, has a luxurious appearance, and is also aesthetically pleasing. [Brief description of the drawings]

[0011] [Figure 1] FIG. 2 is a schematic side view of the expandable ring-shaped jewelry of the present invention in a state before being expanded; [Diagram 2] FIG. 2 is a schematic front view of the expandable ring-shaped jewelry of the present invention before it is stretched. [Diagram 3] FIG. 2 is an enlarged perspective view of a main part of the expandable ring-shaped jewelry of the present invention in an expanded state. [Figure 4] FIG. 2 is a partially enlarged cross-sectional view of the expandable ring-shaped jewelry of the present invention in an expanded state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The expandable ring-shaped jewelry of the present invention will be described in detail below with reference to Figs. In Figures 1 to 4, the expandable ring-shaped ornament 11 of the present invention is configured by setting box-shaped decorative bodies 12, each with an opening 13 inside, side by side facing in one direction, and connecting the box-shaped decorative bodies 12 with tubular connecting portions 14, each of which has a stopper frame 15 on both ends that is inserted into the openings 13 of the box-shaped decorative bodies 12 and engages with the side walls of the openings 13. Furthermore, by inserting a coil-shaped connecting spring 16 into the inside of the tubular connecting portion 14, the multiple box-shaped decorative bodies 12 are connected together and made expandable and contractible via the coil-shaped connecting spring 16.

[0013] Furthermore, each of the box-shaped decorative bodies 12, which has an opening 13 formed inside facing in the aforementioned direction, has a spherical appearance overall with a seat 12a formed on the back surface (see Figure 4), and multiple box-shaped decorative bodies 12, each having a spherical appearance with a seat 12a formed on the back surface, are connected via tubular connecting parts 14. Of course, it goes without saying that the spherical appearance with seat portion 12a formed on the back does not only mean an appearance that is approximately spherical as a whole, but also includes an appearance in which the angular parts (edges) of the box-shaped decorative body 12 have been rounded off.

[0014] Furthermore, the box-shaped decorative body 12 with the opening 13 formed inside facing the one direction naturally has a spherical appearance with a seat 12a formed on the back surface, but it is preferable that a decorative ball 21 is attached to the front surface of the multiple box-shaped decorative bodies 12 having a spherical appearance with a seat 12a formed on the back surface. It goes without saying that the decorative ball 21 can be attached not only to the front surface of the box-shaped decorative body 12 but also to other places. The decorative beads 21 may be gemstones such as sapphire, tanzanite, diamond, pearl, ruby, garnet, emerald, tourmaline, cat's eye, black opal, etc., and of course may be other precious stones or colored glass.

[0015] Next, when assembling the expandable ring-shaped accessory 11 of the present invention, as shown in Figure 4, the box-shaped decorative bodies 12 with openings 13 at their ends are set side by side facing in one direction, and one end of the tubular connecting part 14 set in the box-shaped decorative body 12 is inserted through the opening of the next box-shaped decorative body 12. At this time, the retaining frame 15 at one end of the tubular connecting part 14 is still tubular, so it can be inserted without any difficulty. Next, the end of the tubular connecting part 14 is deformed so that the anti-pullout frame 15 portion engages with the side wall of the opening 13 of the next box-shaped decorative body 12, and the anti-pullout frame 15 of the tubular connecting part 14 engages with the box-shaped decorative body 12 to ensure a secure connection.

[0016] When almost all of the box-shaped decorative bodies 12 have been connected, a coil-shaped connecting spring 16 is inserted into the inside of the tubular connecting portion 14 and both ends are connected, so that the multiple box-shaped decorative bodies 12 are connected and held in an expandable and contractible manner via the coil-shaped connecting spring 16. [Industrial Applicability]

[0017] The present invention can be used as an expandable ring-shaped accessory, and is particularly suitable for use as a bracelet, necklace, or anklet. Furthermore, when attaching a conventional bracelet to the wrist, the clasps attached to both ends of the chain-like body are placed behind the wrist, and the bracelet, for example, must be removed with one hand, which is extremely inconvenient. The expandable ring-shaped jewelry of the present invention is easy to attach and remove, and can be suitably used as a bracelet, necklace, anklet, etc., and ring-shaped jewelry can be provided in a variety of designs.
