Abstract: A mechanical lever buckle having a buckle base plate, a lever element, a buckle prong and a belt loop element having a belt guiding element for guiding a belt in a belt guiding direction is disclosed. The buckle base plate includes an elongated slit oriented in the belt guiding direction. The lever element includes an elongated guiding opening that allows passage of at least a portion of the buckle prong. The lever element is attached to the buckle base plate at a first rotation axis, such that during rotation the elongated guiding opening intersects at all time with the elongated slit and the buckle prong slides along the slit and the elongated guiding opening. The lever element includes a lever tooth that interacts with a belt loop tooth when the lever element is rotated to the determined angle of rotation to block a belt loop element's movement.

Abstract: An adjustment system for a fine and precise adjustment of the size of a strap, such as watch strap, or belt with a part the by rotation creates a rectilinear motion of an adjustment pin that moves two parts of a strap/belt relatively to each other to adjust the length of said strap/belt. The adjustment system also comprises a locking system to block the strap in its adjusted position.

Abstract: The invention provides a mechanical lever buckle (400) that comprises a buckle base plate (402), a buckle prong (30) and a belt loop element (404) having a belt guiding means allowing to guide a belt in a belt guiding direction. The lever buckle (400) further comprises a lever element (406). The buckle base plate (402) comprises an elongated slit (412) with a direction corresponding to the belt guiding direction that allows to slide the buckle prong (30) in belt guiding direction of the slit (412). The lever element (406) comprises an elongated guiding opening (64) that allows to slide the buckle prong (30) in a first length direction of the guiding opening (64). The lever element (406) is attached to the buckle base plate (402) at a first of its extremities around a first rotation axis (61), such that during rotation of the lever element (406) the buckle prong (30) slides along the slit (412) and the elongated guiding opening (64).

Abstract: The cufflink comprises at least an end containing a movable part, a shaft and a wing attached to said shaft, wherein the shaft comprises releasing means cooperating with said moving part to allow displacement of said moving part in a protruding position, and the position of said wing being adjustable with respect to said shaft to allow a variation of the length of said shaft.

Abstract: A buckle mechanism (1), for releasably and adjustably connecting an attachment member (3) to a tongue member (5), comprises a fixed buckle member (2) connected to or adapted for being connected to the attachment member (3). A movable element (4) that is adapted to be connected to the tongue member (5) is slidably mounted inside the fixed buckle member (2) between a first stable position and a second stable position for varying a distance along a pulling direction between said tongue member (5) and said attachment member (3). This mechanism further comprises a manually-operable lever system (6, 6?) for moving the movable element (4) between its first and second stable position.

Abstract: Cufflink comprising an elongated central part (1), adapted for being inserted in a cuff-hole, a first end part (2) extending from a first extremity of said central part (1) in a direction transverse to the longitudinal axis of said central part (1), and a second end part (3) extending from a second extremity of said central part (1) in a direction transverse to the longitudinal axis of said central part (1).
