Claim 1

A non-motorized cart for carrying a rider along a surface, said rider supplying propelling energy for the cart, comprising: a frame including first and second spaced coplanar longitudinally extended members; a front pair and a rear pair of supporting frame members, each pair extending in opposite transverse directions from respective ends of said longitudinally extended members, being curved on an outer transverse portion thereof, and extending downwardly to lower ends; and a front crossbar affixed to the lower ends of said front pair of supporting frame members, said front crossbar extending in said transverse direction and being parallel to the plane of said longitudinally extended members said crossbar including a central, upwardly extending pivot bracket; a seat mounted on said longitudinally extended members; propelling means comprising first and second propelling levers pivotally connected to said first and second longitudinally extended members, each of said propelling levers having an upwardly extending arm and a downwardly extending arm; a rear axle rotatably mounted at the lower ends of said rear pair of supporting frame members, said rear axle having first and second crank portions extending in diametrically opposite directions from the axis of rotation of said rear axle; first and second connecting rods connecting the downwardly extending arms of said first and second propelling levers to the first and second crank portions of said rear axle respectively; and a pair of rear wheels adpated for contacting said surface, one of said rear wheels being mounted at each end of said rear axle; and steering means comprising a pair of brackets, each of said brackets being pivotably connected to a respective end of said front crossbar for rotation about an axis perpendicular to the plane of said longitudinally extended members; steering rod means having ends thereof attached to said brackets; a pair of front wheels adapted for contacting said surface, one of said front wheels being rotatably mounted on each of said brackets; and a lever attached to said steering rod means and pivotally connected to said front crossbar pivot bracket, said lever being provided with pedal means interposed between said front wheels at a height above said surface which is greater than the radius of said front wheels and less than their diameter for displacing the wheels of said cart through a limited angle by rotating said lever about said pivot.
