Abstract:
A device for fastening a shell intended for holding a boot on a snowboard, said shell having on its lower surface, a circular orifice for receiving said device for fastening the shell to the snowboard, characterized in that said device comprises a first component (1) fastened to the snowboard and having portions engaging portions of a second component (2) fixed in terms of rotation to said first component, at the same time leaving said second component free to move in the direction perpendicular to the snowboard over a defined distance, said second component having, on its lower surface, a toothing (21) corresponding to a toothing of said shell, said device also comprising a third component (3) arranged under said first component, and held fixedly thereby in the perpendicular direction, but able to rotate over a defined angle, said third component having, on its periphery, ramp-shaped segmental protuberances (31) in the direction perpendicular to the snowboard, said protuberances engaging corresponding ramps (25) on one side of said second component in such a way that a rotation of the third component (3) over a defined angle causes said second component to be moved downwardly against the shell, while at the same time holding said shell in a defined position relative to the snowboard.
