Patent ID: 7416208

Claim:
A gliding board, comprising: a gliding surface that terminates in at least one raised end, said end being an elevated zone when said gliding board is flat such that said end extends a distance from a low point where said gliding surface begins to elevate and extends to a highest point, of said elevated zone, said end having a peripheral zone and a central zone, the peripheral zone extending from sides of said end toward the central zone of said end, the peripheral zone having a thickness which is less than a thickness of the central zone of said end and being connected to the central zone by a discontinuity that forms an inflexion surface continuously extending throughout a length of said discontinuity in said end to form a smooth arc between said sides of said end, an upper face of the central zone extending to an intermediate point along a center longitudinal axis of said end that is positioned between the low point and the highest point and is closer to the highest point than the low point; and a pair of metal edges adjacent said gliding surface, each of said edges terminating at a point within said end, a width of said peripheral zone being at least 5 mm at a location adjacent said termination point, wherein (i) an upper face of the peripheral zone is substantially parallel to the gliding surface, (ii) a width of the peripheral zone, measured from a nearest point along the side of said end, increases from a value of zero level with a beginning of said peripheral zone to a maximum value at said highest point of said end, (iii) a vertex of said arc extends to a highest point of said inflexion surface along said end at a point substantially along the center longitudinal axis of said end, (iv) said upper face of the central zone is substantially parallel to the gliding surface within said end, and (v) a continuous protective cover extends along said central zone, said discontinuity, and said peripheral zone throughout said end.
