Abstract:
1. An extension device configured to form an elongated, articulated, horizontally rotatable interconnection between a forward, prime mover section of a wheeled vehicle and a rear, load-carrying section of the wheeled vehicle, said device facilitating extension of the length of the vehicle and comprising: an elongated rigid frame having a horizontal longitudinal axis about which said forward and rear vehicle sections can rotate relative to each other and extending between a front end connector that matingly engages with the forward, prime mover wheeled vehicle section and a back end connector that matingly engages with the rear, load-carrying wheeled vehicle section, the elongated rigid frame holding the front and back end connectors in fixed, spaced relationship relative to each other; wherein at least one of said connectors is a pivot connector that enables a rotatable connection about said horizontal longitudinal axis, the extension device being configured to and having sufficient strength to maintain the forward and the rear vehicle sections in longitudinally spaced apart relationship relative to each other, thus extending the length of the vehicle as compared to a non-extended configuration, while permitting the forward and the rear vehicle sections to pivot relative to each other about the horizontal longitudinal axis when the extension device is installed therebetween.
