ABSTRACT:
A suspended personnel carrier includes an elevated cylindrical track from which a carrier is suspended for translation by a bearing assembly. The bearing assembly includes orthogonal rollers which ride along the cylindrical track. The carrier is propelled along the track through a fan drive system including a propeller and a motor. The frame of the carrier is divided into front and rear portions connected by a hinge. A crossed parallelogram linkage suspension connects the front and rear portions, such that turning of the front portion by manual manipulation of a handlebar assembly effects a mirror image movement of the rear portion. The drive motor and propeller are coupled to the frame of a carrier by a slip rail assembly, and to the bearing assembly by a shock absorbing telescoping linkage, such that drive force is first transmitted to the bearing assembly, rather than the frame. This arrangement causes the bearing assembly to pull the carrier, rather than the carrier pushing the bearing assembly, resulting in smoother, more controlled ride around the track.
