Abstract: A wearable physiological signal detecting device includes a device main body and a telescopic structure. The device main body has a strap which surrounds to form a wearable space. The telescopic structure is disposed in the strap and has first surfaces and second surfaces. Each of the first surfaces faces the corresponding second surface. Each of the first surfaces and the corresponding second surface continuously move close and contact each other to assume a first state. The strap can be forced so that each of the first surfaces and the corresponding second surface move away from each other and have an angle to assume a second state. The size of the wearable space when the first surface and the corresponding second surface assume the second state is greater than the size of the wearable space when the first surface and the corresponding second surface assume the first state.

Abstract: The jewelry item comprises an elastic element, which extends along an extension direction of the item through the entire length of the item, and a plurality of ornamental elements, which are threaded one after the other on the elastic element so as to be slidable relative to the elastic element and are non-releasably connected in twos to one another. Each ornamental element comprises a hollow body having a pair of longitudinally opposite first faces, namely a right-hand face and a left-hand face, respectively, and a pair of radially opposite second faces, namely an inner face and an outer face, respectively. The right-hand face of each ornamental element has a through opening communicating with an inner cavity of the ornamental element.

Abstract: Disclosed herein is a low profile expandable ring structure comprising a plurality of coupled blocks that each have a certain degree of translational movement with respect to each other. Each block has one or more downward curved loops or tubes protruding on the front side of the block which are inserted into openings on an adjacent block. A tensioned spring, passed through an internal channel of the coupled blocks, maintains the ring structure in a closed appearance but allows for expansion of the expandable ring structure through the translational movement of the blocks. The low-profile nature allows the expandable ring structure to be comfortable for the wearer.

Abstract: A band comprised of a plurality of link members connected to each other to be able to pivot by pivot shafts, in the band, at least one of the plurality of link members has a sheet member and a wrapped member around which the sheet member is wrapped, the wrapped member has a side part facing an adjoining link member, and at least one end part of the sheet member is arranged between a top end part and bottom end part of the side part in the thickness direction.

Abstract: The invention provides a flexible ring structure made of loosely-linked prisms, which together define an interior channel. A tensioned spring runs through the length of the channel. The ring, which gives the appearance of a solid and rigid circular structure, can be compressed so as to conform to the cross-section of the finger or hand, and springs back to a circular shape when released. The invention makes it possible to wear an Eternity Ring or a bracelet of smaller diameter than could otherwise be put on the wrist.

Abstract: An ornamental rod-like body includes a strap-shaped ornamental body 1 for ornamental purposes includes a multiple granular ornamental bodies 2 selected from the group consisting of jewel, artificial jewel 2A, bead, noble-metal ball, and metal ball; a connecting member 3 configured to arrange the granular ornamental bodies in a plurality of rows and connect them to each other; and an adhesion member having a adhesive layer 4 made of hot-melt adhesive configured to be adhered to a backside of the connecting member. The strap-shaped ornamental body is adhered and secured via the adhesion member in a state where granular ornamental bodies are wound and exposed radially outward of the adhesion member.

Abstract: A flexible piece of jewelry, such as a charm bracelet or necklace, that utilizes non-continuous chain links that constitute the continuous chain of the piece of jewelry. This link design allows more non-continuous links to be added to the bracelet as the child grows and the need for a larger piece of jewelry evolves and minimizes damage to the piece of jewelry caused by the addition of additional charms or links.

Abstract: A 13 mm transitional modular Italian charm link capable of connecting to smaller 9mm charm links and/or other 13 mm charm links in various combinations. Charm links connect to one another using a spring loaded hook and post combination with the hook element emanating from the charm face to maintain the continuity of the bracelet but the hook elements of existing charm links do not properly mate with charm links of a different size. The present invention provides a charm link that may be configured in any of three configurations having a transitional hook and/or transitional post to accommodate charm links of a smaller width.

Abstract: Starting with an article of the so-called “gas pipe” type which is formed from two concatenated spiral components (1, 3) and is deformed into a noncircular configuration, the article is cut lengthwise (7) to cut the turns of the two components, which remain connected without relative movements.
