Buckle i.e. butterfly buckle, for connecting flexible sections of e.g. watch strap, has control rod device constituted of detent adjusting spring to control movement of sliding element, and safety pin arranged parallel to axis of strap/belt

摘要

The buckle has a length adjusting device (55) including a sliding element i.e. slide (72), that slides along a direction parallel to an axis of a strap or a belt to adjust the length of the strap or the belt. A safety pin (76) cooperates with a perforation in a section of the strap or the belt, and is arranged parallel to the axis of the strap or the belt. A control rod device is constituted of a detent adjusting spring (58) to control the movement of the sliding element. The control rod device comprises two elastic arms that interact with corresponding notched surfaces of an opening.
