Abstract
A floating track device for releasable attachment to a drive mechanism of an existing vehicle for supporting, floating, moving and steering the vehicle on a traveling surface includes an endless belt member to weight support the vehicle on the traveling surface. The endless belt member includes a belt endless inner layer spaced from a belt endless outer layer so as to define a plurality of inner and outer surface sections there along. The inner and cuter surface sections form generally elongated floating members positioned adjacent relative to each other and forming housings in which buoyant bodies are disposed. Each outer surface section forms an external corrugation of the endless belt member for traction. Each inner surface section includes an internal corrugation for releasable driving engagement with the vehicle drive mechanism. Holding rods, separating two adjacent floating members, hold and secure the complementary inner and outer surface sections to each other.
