  • Patent number: 5560050
    Abstract: A combined toilet and waste holding tank is provided for mounting within a portable toilet cabana having side walls, a rear wall, and a front wall with a door and a floor. The tank extends along the rear wall and between the side walls and occupies roughly the rear half of the cabana floor space. The toilet includes a ring-like structure having a rear portion opening directly into the tank through a cover panel upon the upper surface of the tank, and also having a forward extending, bowl-like portion which is integral with and extends forwardly of the front wall of the tank. The cabana has a rear-to-front extending central axis which approximately bisects the cabana. The toilet structure is located substantially on one side of the cabana axis, so that it is closer to one side wall of the cabana and the toilet is acutely angled relative to the cabana axis.

  • Patent number: 5500962
    Abstract: An outdoor toilet cabana is formed of pair of side walls whose opposite vertical edges are bent to form angled corner sections having their free edge portions bent into vertical strip-like flanges that extend in approximately the same plane towards the opposite, corresponding flanges of the opposite wall. A rear wall has side edge strip-like portions that are aligned in approximately the same plane as the flanges of the side wall. Extruded strips are formed with oppositely opening channels to receive the adjacent side wall flanges and rear wall edge portions. These channels are deeper than the portions of the flanges and rear wall strips received therein so that they can accommodate variations in wall dimensions while still providing a rigid cabana of pre-determincd size. A doorway is formed between the flanges on the forward side of the side walls. A substantially continuous extruded doorway edge strip extends along the jambs and the header of the doorway.

  • Patent number: 5500960
    Abstract: A flushing system is provided for an outdoor portable toilet of the type having a cabana containing a waste material storage tank upon which a toilet structure is positioned for the deposit of toilet waste material into the tank by gravity. A separate fresh water tank is removably positioned outside the cabana against its rear wall and is connected, through a pipe, to a control valve, which, in turn, is connected to a flushing mechanism and a pump which conveys liquid to the flushing mechanism when actuated. In addition, a waste tank pipe extends into the waste tank and a filter through which waste liquid may be drawn from the waste tank to the valve and then pumped to the flushing mechanism. The valve may be set to draw liquid either from the fresh water tank or the liquid from the waste water holding tank or, alternatively, from neither tank, so that the unit may be operated without flushing.
