Abstract:
A sliding apparatus comprising:an elongated board extending along a central axis from a first end to a second end, said elongated board having flexion and torsion characteristics and including a top surface, a bottom surface, and a pair of side edges extending in a direction substantially parallel to said central axis,said elongated board including an elongated ridge extending along a central portion of the top surface and including a side shoulder extending along each side of the top surface, said elongated ridge and said side shoulders forming two recessed channels in the top surface, each of said channels extending substantially parallel to the central axis adjacent to one of said side edges,at least one pair of rigid stiffening elements for changing the flexion or torsion characteristics of said elongated board, each of said stiffening elements extending along a longitudinal axis and being removably fastenable to said elongated board in one of said channels;fastening means for securely and releasably fastening said at least one pair of stiffening elements at respective first locations in said recessed channels along the length of said elongated board, whereby said stiffening elements are not substantially moveable with respect to the top surface of the elongated board when fastened by said fastening means; andmeans for adjusting the locations of said stiffening elements in said channels within predefined ranges with respect to said first locations.
