A tool is provided that includes a plurality of links including at least three links movably interconnected to one another to form at least a portion of a wearable accessory, such as a bracelet. The plurality of links are articulatable so as to alternately assume a first configuration in which the plurality of links extend linearly, a second configuration in which the plurality of links are curved about an axis in a first direction and a third configuration in which the plurality of links are curved about the axis in a second direction, opposite the first direction. The plurality of links are configured to permit limited motion in a direction parallel to the axis prior to becoming structurally rigid. At least one link includes at least one tool function. A clasp and a receiver are also provided to facilitate the functionality and versatility of the resulting wearable accessory.

A wearable smart band and comprises a fixing band provided so as to be wearable on a joint of a user including a human, an animal, a machine, etc., a receptacle member formed on the fixing band so that a tool, a machine part, a device, and an information device is located, and having an upper part covered by a cover; a flexible band provided on one side of the fixing band, whereof the shape of the fixing band is transformed according to movement of the user's joint; and an inserting and drawing assembly having one end connected to the flexible band and the other end connected to the information device or the cover, wherein the information device or cover is drawn or inserted from or into the receptacle member by the transformation of the flexible band according to the movement of the user's joint.

The present invention relates to the field of chain straps, in particular to an easy-to-disassemble length-adjustable chain strap, including: several middle chain links, wherein one end of each middle chain link is inserted with a connecting needle with an end exposed to the outside of the middle chain link; and one part of each pulling component is fitted into each middle chain link, and the other part of the pulling component is rotatably inserted into one edge link I correspondingly. According to the present invention, the length of the chain strap can be easily and conveniently adjusted by hand without using any tools under normal conditions. The way of adjusting the length of the chain strap is: gently pulling the edge link I outward with fingers and then rotating the same at a small angle to directly disassemble two adjacent middle chain links.

A link component for a jewellery item includes a hollow body with substantially opposed, spaced side surfaces, one or more junction elements connecting the side surfaces, at least one connecting arm projecting outwardly from one side surface, and a through opening on the opposed side surface. The connecting arm of one link component is designed to be inserted into a corresponding through opening of an adjacent link component. At least one pin with a substantially polyhedral shape and dimensioned smaller than the overall dimensions of such connecting arm is provided on one of the side surfaces, and a corresponding connecting through hole having shape and dimensions substantially equal to those of the pin is on the opposed side surface. The pin of a link component is inserted into a corresponding connecting through hole of an adjacent link component, to prevent relative rotation around the axis of the pin.

A modular element for making jewellery items, trinkets, and the like, having a convex outer surface and a through hole arranged at the top of the outer surface, where a wire, chain, or support for making the jewellery item, trinket, and the like can be inserted through the through hole, a main axis of symmetry passing through the hole, including a concave inner surface intended to at least partially accommodate the outer surface of a second element adjacent to the first one, where the outer surface can be inscribed on a rotation surface whose generatrix is an arc of a conic section and whose axis of rotation coincides with the main axis of symmetry. Embodiments also include a jewelry item.

A wearable electronic device includes a conductive housing, which has a main body and at least a first pair of conductive lugs external to and mechanically coupled to the main body. The main body of the conductive housing forms at least part of an antenna structure that is adapted for at least one of generating or receiving the wireless radio frequency signal. The wearable electronic device further includes a non-conductive pin, which extends between the ends of the conductive lugs, and a use location attachment. The use location attachment includes a plurality of segments, where at least one of the segments, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, is nonconductive, and where other ones of the plurality of segments of the use location attachment are conductive.

A wearable smart band and comprises a fixing band provided so as to be wearable on a joint of a user including a human, an animal, a machine, etc; a receptacle member formed on the fixing band so that a tool, a machine part, a device, and an information device is located, and having an upper part covered by a cover; a flexible band provided on one side of the fixing band, whereof the shape of the fixing band is transformed according to movement of the user's joint; and an inserting and drawing assembly having one end connected to the flexible band and the other end connected to the information device or the cover, wherein the information device or cover is drawn or inserted from or into the receptacle member by the transformation of the flexible band according to the movement of the user's joint.

A jewelry assembly comprising interchangeable jewelry elements and a kit including the same are provided. The jewelry assembly comprises a main portion having two locking members disposed on opposing ends of the main portion and an interchangeable portion comprising two connection sites disposed on opposing ends of the interchangeable portion. The locking members and connection sites are configured such that the locking members may removably secured to the connection sites to form a wearable loop, such as a necklace or bracelet.

A jewelry chain having a plurality of links including a plurality of connecting links and one or a plurality of decorative links. Each decorative link comprises alphanumeric character having one or more outline members which becomes part of the chain by connection from at least one connecting link. The connecting link can easily pass through an open section of the outline member to allow rotation and sliding movement in at least two different directions so that the alphanumeric character can provide different appearances when the jewelry chain is worn.

One additional outline member or a portion of an open section of an outline member can include one or more gemstones provided upon a mounting structure therein. The chain can form or be incorporated in necklaces, bracelets or earrings.

A flexible band wearable electronic device includes a plurality of rigid links. The flexible band wearable electronic device also includes a number of pivot joints coupling the plurality of rigid links together. The flexible band wearable electronic device further includes a first electronic device on a first of the plurality of rigid links, and a second electronic device on a second of the plurality of rigid links. The flexible band wearable electronic device still further includes an electrical communication pathway between first electronic device and the second electronic device and through at least a portion of one of the number of pivot joints.
