Articulated unit vehicle
First Claim
1. An elongated vehicle adapted to be propelled along an engaging surface and capable of climbing over obstacles on said engaging surface, including:
- a plurality of individual wheeled units, including front and rear units, each unit having supports for two laterally extending, longitudinally spaced axles which have wheels mounted on the ends of the axles,each unit, except for the front an rear units of the vehicle, having two axles, both of which are shared with adjacent units, the front and rear units each having two axles but sharing only one axle with an adjacent unit,each unit having a body mounted on its axles which body is rotatable relative to each of the axles,each body including side members which are held in spaced relationship to each other by a top member, said axle supports being formed in said side members, said side members of the bodies of adjacent units intermeshing and overlapping to permit the axle supports of adjacent units to be aligned to receive the shared axles,stop means formed on the bodies independently of the top members and positioend to engage one another to limit rotation of adjacent units relative to one another about their shared axles to prevent one unit from folding back over an adjacent unit, andmeans to drive at least some of said wheels to propel said vehicle along the engaging surface.

Abstract
An elongated vehicle adapted to be propelled along an engaging surface and capable of climbing over obstacles on the engaging surface. The vehicle has a plurality of wheeled units including front and rear units with each unit having two axles and wheels mounted on the ends of the axles. Each unit, except for the front and rear units, shares its two axles with adjacent units. The front and rear units each share only one axle with an adjacent unit. Each unit has a body mounted on the axles and the body is rotatable relative to each of the axles. Each body includes side members to maintain the axles spaced apart longitudinally. The side members of the bodies of adjacent units intermesh and overlap at their shared axles to allow adjacent units to rotate vertically relative to each other. The side members include stop surfaces to limit rotation of adjacent units relative to one another about their shared axles. A drive mechanism is provided to drive the wheels.
