  • Patent number: 5933882
    Abstract: A flush toilet for a recreational vehicle has a flush mechanism including a lever that can be either depressed to cause a full flush of the toilet, or raised to rinse the bowl only. The lever operates a linkage that is designed so that, even after a partial failure of the linkage, the linkage can still be operated to introduce water into the bowl.

  • Patent number: 5906011
    Abstract: A flush toilet for a recreational vehicle has a flush mechanism including a pair of foot pedals, one for opening the bowl outlet closure of the toilet, and the other for opening the flush water valve. Depression of the first foot pedal also depresses the water valve foot pedal, though that pedal can also be operated separately. An actuating cable for the water valve extends through the arm of the bowl closure foot pedal so that, if the water valve foot pedal breaks or is damaged, the water valve can still be opened for rinsing the bowl.

  • Patent number: 5815852
    Abstract: A flush toilet, for example, for use in a recreational vehicle comprises two main plastic mouldings, one of which includes the toilet bowl and the other of which forms a "shell" or outer housing in which the bowl is supported so that the bowl outlet is located in an internal space defined by the shell. In accordance with the invention, the toilet is provided with a flushing mechanism that includes a bowl rinse nozzle adjacent the rim of the bowl and an internal rinse nozzle for rinsing the walls of the internal space and flushing mechanism within the outer shell. This reduces the risk of odours developing from contamination of the shell and also means that the shell is relatively clean inside in the event that servicing of the toilet is required.
