Patent ID: 8459667

Claim:
A handlebarless foot-propelled wheeled hobby and/or sport device, which has a wheel ( 1 ) disposed between two side-plates, the side-plates suspended on an axle (X) of the wheel ( 1 ); foot-boards ( 5 ) disposed below the axle (X) of the wheel ( 1 ), protruding outwards, coupled to the side-plates; wherein the side-plates project over the foot-boards ( 5 ), and extend in a direction parallel to the wheel thereby providing supporting surfaces (a) for each knee of a user of the device, said supporting surfaces configured to extend so as to transfer horizontal force to a substantial portion of an inner side of each said knee in a direction perpendicular to a traveling direction of the wheel when the user is accelerating the device by foot propulsion wherein at a predetermined distance (e) behind the wheel, with respect to the travelling direction, there is a structure ensuring stabilisation against tilting in the traveling direction; wherein the supporting surfaces are substantially flat and sized so as to act against the entire side of each knee, which surfaces are adapted to transfer the horizontal force to the inner side of each knee; wherein the structure includes a satellite wheel with a diameter substantially smaller than that of the wheel, said structure disposed behind the wheel with respect to the traveling direction and is coupled to at least one of the side-plates; wherein the satellite wheel is configured to allow the device to freely tilt in a direction perpendicular to the traveling direction.
