<p>The invention provides a mechanical lever buckle that comprises a buckle base plate, a buckle prong and a belt loop element having a belt guiding means allowing to guide a belt in a belt guiding direction. The lever buckle further comprises a lever element. The buckle base plate comprises an elongated slit operated in the plate with a direction of the elongation slit corresponding to the belt guiding direction, having a first width that allows to pass through at least a portion of the buckle prong and to slide the buckle prong in belt guiding direction of the slit. The lever element com¬ prises an elongated guiding opening having a second width that allows to pass through at least a portion of the buckle prong and to slide the buckle prong in a first length direction of the guiding opening. The lever element is attached to the buckle base plate at a first of its extremities around a first rotation axis that has a direction passing through the buckle base plate, such that it may rotate around the first rotation axis while during rotation the elongated guiding opening intersects at all time the slit and such that during rotation the buckle prong slides along the slit and the elongated guiding opening. The belt loop element is movably fixed to the buckle base plate and comprises a belt loop tooth that allows to block any belt loop element's movement relative to the buckle base plate. The lever element comprises a lever blocking means that interacts with counter part lever fixing means of the buckle base plate to block the lever element at a determined angle of rotation, and a lever tooth that is integral with the lever element. The lever tooth interacts with the belt loop tooth when the lever element is rotated to the determined angle of rotation to block the any belt loop element's movement.</p> |
