A band piece including a first piece which has a connection recess recessed in a piece connection direction and a connection projection projecting in the piece connection direction, a second piece which is arranged on one surface of the first piece while corresponding to the connection projection of the first piece, and an engaging portion which engages the first piece with the second piece.

A watch strap and a smart watch includes: a plurality of strap blocks arranged consecutively in one direction; and a plurality of hinge coupling units pivotably coupled to both sides of the plurality of strap blocks to integrally connect the plurality of strap blocks to each other. An all-solid-state battery having electrode terminal units on both sides thereof is embedded in at least one of the plurality of strap blocks. At least one of the plurality of hinge coupling units is electrically connected to one of the electrode terminal units.

Disclosed is a jewelry module in which each core module is formed by connecting each other in jewelry produced by processing precious metals. The jewelry module has a rotation bed having an axis of rotation formed so as to be centered on the joining axis of each core module. Additionally, an angle of rotation with a reduced distance away from the rotational movement of each core module by the presence of said axis of rotation is provided, and a connection bracket is centered on the axis of rotation, which grasps the rotation bed and enables one core module to be connected with the other core module.

A band for a wearable device includes first and second band links. The first band link includes one or more magnetic pins and the second band link includes one or more magnets and one or more apertures. In a first position, the first and second band links mechanically and magnetically couple by the magnet pulling the magnetic pin into the aperture. In a second position, the first and second band links mechanically and magnetically decouple by the magnetic pin being forced from the aperture. In this way, the band links may be easily and quickly coupled to and/or decoupled from each other.

A watch type terminal includes a main body, and a strap connected to the main body. In the watch type terminal, the strap includes one or more modules each having a specific function, and one or more partition straps having the one or more modules respectively received thereat. In the strap, the module and the partition strap are electrically connected to each other.

The present invention(s) seeks to protect Applicant's link, link chain and methods of making, transforming and using such. The link, for use in series to form a multi-positionable link chain includes a through hole and a first and a second diagonal channel on a top and a bottom side running in opposite directions. Generally, the geometry of the links, and specifically, material removed from and/or sharpened edges of the through hole, the diagonal channels and/or corner portions of the modified rectangular solid links, is such to allow for relative rotation and/or multiple points of connection of adjacent links. The link chains of the present invention(s) are flexible in the length, width and height dimensions to allow adaptable transformation in a plurality of stable configurations. And they can include a clasp for ornamental and/or decorative use.

An interlocking bead-plug system in which the beads are rubber or silicone and can be plugged together to create a chain. Each bead may have a female end with a hole and a male end with a protruding plug on opposing ends. The plug may be circular, elevated, and rubber. The hole can be stretched so that a second interlocking bead can fit through. The plug of the interlocking bead fits securely into the hole of the originating bead, creating the chain of beads.

A band for a wearable device includes first and second band links. The first band link includes one or more magnetic pins and the second band link includes one or more magnets and one or more apertures. In a first position, the first and second band links mechanically and magnetically couple by the magnet pulling the magnetic pin into the aperture. In a second position, the first and second band links mechanically and magnetically decouple by the magnetic pin being forced from the aperture. In this way, the band links may be easily and quickly coupled to and/or decoupled from each other.

The disclosure herein relates to methods used to facilitate the assembly of chain-links. In particular, the disclosure relates to using a coupling mechanism comprising at least one coupling pin and at least one coupling socket to form a chain element in various ornamental and decorative forms. Accordingly, the coupling socket of a chain-link element is configured to accommodate a pin-head associated with the coupling pin in a pin-bed associated with the coupling socket. Furthermore, the coupling mechanism comprising a locking mechanism configured to fasten the pin-head into its associated pin-bed. Thus, the disclosed coupling mechanism provides an alternative to using soldering technique in the chain making field, enabling to assemble chain-link elements, especially of jewelry chains, which are typically made of precious metals, mainly gold and silver.

Systems and methods for aligning an accessory with a mesh carpet to provide an improved transition between the components. Various embodiments include the use of one or more alignment points or features on a portion of the mesh carpet to be aligned with an accessory. The alignment features may identify one or more high points on the coil structures comprising the mesh carpet at the portion of the mesh carpet to be aligned with an accessory. Once identified, the alignment features may be used to guide the alignment of the accessory with the mesh carpet.
