U-shaped float tube with stabilizing frame

Abstract

This invention is of a float tube or watercraft comprised of a generally U-shaped inflatable flotation chamber having two generally parallel and laterally disposed leg portions and a rearward portion. The leg portions are preferably formed integrally with the rearward portion. The invention further includes a seating device bridging the two leg portions of the flotation chamber. The invention also has a novel U-shaped stabilizing frame and means for connecting the stabilizing frame to the U-shaped flotation chamber. The U-shaped frame provides support to the opposing legs of the flotation chamber and prevents them from pinching in on the occupant. For additional support, a rigid rod, or tube, extends between the opposing legs of the frame. The means for connecting the stabilizing frame comprises preferably a plurality of channel segments, which are fixedly secured to the leg and rearward portions of the flotation chamber. Alternatively, a continuous channel may be used. In either case, the channel conforms to the U-shape of the flotation chamber and cooperatively and removably receives the U-shaped frame. Typically, the U-shaped stabilizing frame is retained in the channel segments, or continuous channel, generally inside the interior space of U-shaped flotation chamber and substantially in the same plane as the chamber's central axis though alternative placements are possible.
