ADJUSTABLE LINK Russian patent published in 2016 - IPC A44C5/02 A44C5/14 A44C5/24 

FIELD: manufacturing technology; personal usage items.

SUBSTANCE: invention relates to an adjustable link for a bracelet or a wrist joint. Adjustable link (1) for a bracelet contains first half (2) and second half (3) of the link, which are movable in the longitudinal direction due to interaction of guides and additional guides and are fixed due to interaction of stopers and additional stoppers. First half (2) of the link comprises a longitudinal pin with fasteners (24) having radial return elastic facilities displacing between the folded and the unfolded positions. Second half (3) of the link comprises longitudinal channel (33) for that pin to pass only in one of those folded and unfolded positions, next to channel (33). Additional fasteners are made with the possibility of interaction in at least one fixing position with the said fasteners (24) in the other of the said folded and unfolded positions. Fasteners (24) and additional fasteners together determine at least two of those separated in the longitudinal direction fixing positions. Connecting and fixing element is made in the form of tubular element (28) forming return elastic facilities able to take various positions between the compressed position and the free, extended position. In the compressed position under the action of applied compressive force or during a relative movement between second half (3) of the link and first half (2) of the link, when element (28) is compressed due to additional bearing surface of second half (3) of the link, element (28) is retained inside boundary surface (27). Also proposed are a clasp, a watch, a bracelet, which include the said adjustable links.

EFFECT: provided is the possibility to exclude special tools when using the adjustable mechanism, which remains concealed, ease of control, excluded loss of a bracelet.
