Patent ID: 8020887

Claim:
A ski or snowboard comprising a gliding board body having a length extending in a longitudinal direction, a depth, a width, and a middle portion by reference to the width, said gliding board body being multi-layered and comprising: at least one strength-imparting top belt; at least one strength-imparting bottom belt; at least one core disposed in between the at least one strength-imparting top belt and the at least one strength-imparting bottom belt; at least one top layer forming a top face; at least one running surface facing forming a bottom face; at least one slot provided in the middle portion, said at least one slot having a depth extending from the top face of the gliding board body toward the at least one running surface facing so that the at least one slot divides at least (i) the at least one strength-imparting to belt, (ii) the at least one strength-imparting bottom belt and (iii) the at least one core into a first section defining a first gliding board slat positioned to the left of the at least one slot and a second section defining a second gliding board slat positioned to the right of the at least one slot, said at least one slot having a slot length extending essentially parallel to the longitudinal direction, said at least one slot causing a cross sectional weakening and reducing stiffness of the gliding board body transversely to the longitudinal direction; and at least one geometry-influencing mechanism comprising a plate-type force-transmitting element extending more than 50% of the length of the gliding board body and supported longitudinally in at least part portions on the top face of the gliding board body to transmit load, the plate-type force-transmitting element overlapping the at least one slot in the longitudinal direction and bridging the at least one slot transversely to the slot length, said at least one geometry-influencing mechanism producing a variable cross-sectional shape or contour of the gliding board body, the variable cross-sectional shape or contour being variable manually or as a function of load; wherein the first gliding board slat lies essentially parallel to the longitudinal direction of the gliding board body; wherein the second gliding board slat lies essentially parallel to the longitudinal direction of the gliding board body; and wherein the plate-type force-transmitting element has a high torsional or twisting stiffness so that when one of the first gliding board slat and the second gliding board slat is affected by loads, a height offset in a direction perpendicular to the at least one running surface facing is inhibited or prevented within a portion of said one of the first gliding board slat and the second gliding board slat lying parallel to a portion of the at least one slot overlapping with the plate-type force-transmitting element.
