Sail-propelled land vehicle

A vehicle comprising:

• a carrying board structure of a generally flat elongated configuration having an upper face and a lower face, and two lateral edges symmetrical with respect to a longitudinal symmetry plane;
• two longitudinally spaced axle supporting means elastically hingedly mounted on said lower face of said board structure;
• travelling means having low frictional contact surfaces for displacement of the vehicle on loose or firm surfaces;
• a pair of axles, each having two opposite ends and adapted for being mounted within one of said axle supporting means so as to extend substantially perpendicularly to said longitudinal symmetry plane, and to have said opposite ends of each axle symmetrical with respect to said longitudinal symmetry plane and extending beyond said lateral edges of said board structure;
• a sail-carrying mast structure comprising sail control means and equipped with a hinged mast-supporting means;
• mounting means on said upper face of said board structure for removably receiving said mast supporting means, said mounting means being arranged at the vicinity of one of said axle supporting means mounted on said lower face of said board structure;
• said travelling means being mounted by pairs at said opposite ends of said axles, the distance between two paired travelling means being greater than the maximum width of said board structure between said lateral edges;
• said axle supporting means comprise an axle supporting body and a base member;
• said base member having a substantially flat upper surface and a lower surface which has a cross-section the configuration of an inverted wide open V having flat inner wing surfaces;
• means being provided for rigidly attaching said base member by said upper face thereof onto said lower face of said board structure;
• said axle supporting body being formed with a transversal recess for receiving an axle and being connectable to said base member by a pivot member having one end mounted within said body and having its other end loosely received within a bore formed in said lower surface of said base member, and by a connecting screw screwed within a tapped bore formed within said lower surface of said base member;
• said screw passing through at least one resilient damping member interposed between said body and said base member;
• said screw and said pivot member each extending substantially perpendicular to the flat inner wing surfaces of said V-shaped lower surface of said base member;
• means being provided for holding a tubular axle within said recess and for preventing same from displacement in a direction perpendicular to said longitudinals symmetry plane of said board structure.
