Abstract: A sliding partition enclosure system for a modified portable commode cabana with a private urinal cabana, providing simultaneous dual use. A commode cabana's internal compartment includes a commode and waste containment chamber disposed below. An external shell including: a roof, three wall panels, a front panel with latching door and a floor panel with external parallel tracks, a urinal affixed upon the external shell, a drainage system connecting the externally mounted urinal to the enclosed waste containment chamber. A sliding partition unit when extended, provides the private urinal cabana enclosure, including: two horizontally side panels on external parallel tracks of the commode cabana, a front panel with latching door, a roof, and a floor panel hinged to the commode cabana's floor that folds down, stabilizing the sliding partition enclosure when in use. The floor folds up and the partition slides closed when not in use for portability.

Abstract: The disclosure herein provides a two-wheel bicycle system wherein a pair of long levers are arranged on the cross-beam of the frame, to provide the fulcrum for the motion of the levers. The tops of the levers comprise handles perpendicular to such levers, with linkages to a circular and rotatable crank, which rotates in a plane parallel to the ground about a column commonly found in the steering mechanism for such a bicycle. The bottom ends of the levers connect to linking members to connect such levers to the pedals commonly found in such a bicycle. Such linking members are provided so that they are disconnected and then rotatable to be mounted on the diagonal frame piece of the bicycle, when the bicycle is used with hand-operated steering and foot-operated power. Before disconnection, only upper body energy is used to control both steering and powering the bicycle.
