In a vehicle, the combination comprising: an open-centered frame; an operator's seat mounted on said open-centered frame and disposed within the interior of said open-centered frame; a front drive axle mounted for rotation at the front of said open-centered frame which is adjustably mounted on said open-centered frame whereby the distance between said operator's seat and said drive means can be adjusted; a rear wheel castor pivotally mounted at the rear of said open-centered frame and having an axial extent which is less than the axial length of said front drive axle; a pair of ground engaging front drive wheels, one connected to each end of said front drive axle and disposed on the exterior of said open-centered frame; a ground engaging rear steering wheel connected to said rear wheel castor; drive means mounted on said front drive axle and disposed within the interior of said open-centered frame between said front drive wheels for rotating said front drive wheels; a pair of steering levers, one movably mounted on each side of said open-centered frame; and a pair of steering rods, each having one end connected to one of said steering levers and its other end connected to said rear wheel castor to turn said rear steering wheel in response to manual actuation of said steering levers.
Claim 7
Dependent Claim
297 words
In a vehicle, the combination comprising: an open-centered frame having a pair of longitudinal side members spaced from one another that extend from the front to the rear of the vehicle, and a pair of transverse members, one at the front and the other at the rear, which extend between the longitudinal side members to form therewith a wrap-around frame that forms a vehicle perimeter; an axle rotatably mounted toward the front of said open-centered frame with a pedal portion between said longitudinal side members and wheel receiving portions cantilevered outboard from said longitudinal side members; a front drive wheel rotatably mounted on each said wheel receiving portion; an operator's seat with cushion and back portions located toward the rear of said open-centered frame and between said longitudinal side members, with the cushion portion at an elevation beneath said longitudinal side members and the back portion rising above said longitudinal side members, whereby said seat is disposed within the open-centered frame; a support member interconnecting the rear of said back portion and said rear transverse frame member; a rear wheel castor carried by said support member that pivots about an upright axis; a rear steering wheel rotatably mounted by said rear wheel castor; a pair of steering control arms extending sideward from each side of said rear wheel castor; a pair of steering levers each pivoted at its midsection to one of said longitudinal side members with a handle portion rising above its associated side member that moves in a fore and aft direction and a lower arm portion beneath the point of pivot; and a pair of steering rods each connected between the lower arm portion of a steering lever and one of said steering control arms, said rods extending convergent rearward beneath said open-centered frame.
Claim 8
Dependent Claim
