A jewelry link assembly and a method of assembling jewelry chain links are disclosed. The jewelry link assembly comprises a male member comprising a ball portion having two prongs at opposite ends. The jewelry link assembly comprises a female member having two wings. Each wing comprises a prong receiving section. The ball portion is received between the two wings such that the prongs are made to slide into the prong receiving sections provided at the two wings for interlocking the male and female members. The jewelry link assembly further comprises chain links connected at far ends of the male and female members for forming a two-piece design configuration of the chain links together with the male and female members. The chain links, and the male and female members, are connected alternatively and successively to form a jewelry link assembly.

A flexible jewelry cable includes a plurality of helical links. Each link has a body that extends helically about a central axis of the link. Each link includes a protrusion extending from an inner surface of the body at or near ends of the body. Each protrusion defines a through hole that is coaxially aligned with the body. The body defines a female recess on the inner surface of the body, each recess corresponding to one protrusion. The recesses are at or near the ends of the body. One recess of a first one of the links is configured to receive one protrusion of a second one of the links and align the hole of the received protrusion with the hole of one protrusion of the first link. The cable includes a string extending through the aligned holes of the protrusions of the links.

A wrist band for attaching a portable electronic device to a user includes articulating segments which may be releasably connected so as to provide the user the capability of sizing the wristband by adding or removing links as desired. A clasp is also disclosed for securing the wristband to a user. A manufacturing device and method are disclosed for machining complex surfaces on the segments and clasp.

A flexible device includes two opposite sides and a flexible functional element. Each side includes a movable element having a top portion. The flexible functional element includes a flexible functional screen and a support plate supporting the flexible functional screen. The support plate includes a plate body and fixing sheets extending from the plate body. The plate body separably abuts against the top portions of the movable elements, and the fixing sheets fix to the movable elements.

A wearable device is disclosed. The wearable device includes a first section and a second section with a latch there between. First grooves are provided in the first section and second grooves in the second section. At least one guide path is provided to the first grooves to enable guiding of a plurality of design members into or out of the first grooves and the second grooves. A locking pin allows locking the design members within the first grooves and the second grooves. At least one protruding member is provided adjacent to the first grooves or the second grooves to receive the latch and to releasably lock the first section to the second section when the wearable device is worn.

A band of the present disclosure includes: a spring bar including a shaft member and an operation portion; an outer piece including a first arm portion and a second arm portion; and a middle piece disposed between the first arm portion and the second arm portion. The first arm portion includes a first recessed portion provided along an axial direction of the shaft member, the second arm portion includes a first insertion hole provided along the axial direction, and the middle piece includes a second insertion hole provided along the axial direction, and a second recessed portion provided along the axial direction and in communication with the second insertion hole. The spring bar is inserted through the first recessed portion, the second insertion hole, the second recessed portion, and the first insertion hole. The operation portion is disposed protruding from an opening of the second recessed portion.

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 connector including a cylindrical member which has a stopper provided on an end and an opening provided in an outer circumferential surface while extending to the end along an axial direction, a slide member arranged in the cylindrical member, and an operation member attached to the slide member through the opening of the cylindrical member.

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.
