Abstract
Abstract A vehicle frame is provided and includes opposite side support wheels journalled from the frame. Each of the support wheels has a pair of first and second drive wheels journalled from the frame operatively associated therewith. Each pair of first and second drive wheels is drivingly interconnected by means of an endless drive member trained thereabout and one of the drive wheels of each pair is drivingly connected to the corresponding support wheel of the frame. A pair of elongated levers are provided and the levers are disposed on opposite sides of the frame and extend generally transversely thereof. The outer ends of the levers are anchored to the corresponding endless drive members for orbiting therewith about the corresponding pair of first and second drive wheels and the inner ends of the levers are provided with hand grips for engagement by the hands of a person seated along the longitudinal center line of the vehicle. In this manner, the levers may be utilized in the manner of oars in order to propel the vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A wheeled vehicle with oar-type drive assembly, said vehicle including a main frame, a plurality of support wheels journalled from said frame, first drive wheel means drivingly connected to one of said support wheels and journalled from said frame for rotation about a first axis, a second drive wheel means journaled from said frame for rotation about a second axis spaced from and generally paralleling said first axis, an endless drive member trained over said drive wheel means, an elongated lever, means universally anchoring one end of said lever to said drive member for orbiting therewith about said drive wheels, and means universally anchoring a mid portion of said lever relative to said frame, the other end of said lever including hand grip means.
Claim 2
Dependent Claim
124 words
A wheeled vehicle with oar-type drive assembly, said vehicle including a main frame, a plurality of support wheels journalled from said frame, first drive wheel means drivingly connected to one of said support wheels and journalled from said frame for rotation about a first axis, a second drive wheel means journaled from said frame for rotation about a second axis spaced from and generally paralleling said first axis, an endless drive member trained over said drive wheel means, an elongated lever, means universally anchoring one end of said lever to said drive member for orbiting therewith about said drive wheels, and means universally anchoring a mid portion of said lever relative to said frame, the other end of said lever including hand grip means.
Claim 3
Dependent Claim
21 words
The combination of claim 1 wherein said drive wheel means are journalled from said frame for rotation about generally horizontal axes.
Claim 4
Dependent Claim
132 words
The combination of claim 1 wherein said vehicle includes a pair of opposite side support wheels, said first drive wheel means including a pair of first drive wheels drivingly connected to said opposite side support wheels, said second drive wheel means including a pair of second drive wheels associated with said pair of first drive wheels, a pair of endless drive members trained over each pair of first and second drive wheels, and a pair of opposite side levers having one pair of ends anchored to corresponding endless drive members and mid portions of said levers universally anchored relative to said frame, the other pair of ends of said levers being disposed adjacent the longitudinal centerline of said vehicle and manually engageable in the hands of a person seated along said centerline.
Claim 5
Dependent Claim
80 words
