Recreational vehicle toilet with foot pedal flush

Claim 2

Toilet apparatus with foot pedal flush comprising a housing, a toilet bowl mounted on said housing and having an outlet at its lower end and a closure member movable between positions opening and closing said outlet, and flush water supply means including a discharge nozzle operatively associated with said bowl for supplying flush water to the upper end of the bowl, the improvement comprising foot pedal apparatus mounted on said housing for movement in up and down directions, a closure member control lever and a flush water control lever both rotatably mounted to said housing, said closure member control lever coupled to said closure member for moving said closure member to said open position in response to rotation of said closure member control lever in a first direction, said flush water control lever coupled to said flush water supply means for opening said supply means to supply flush water to said bowl in response to rotation of said flush water control lever in said first direction, a pair of flexible control wires contained in conduits mounted to said housing for sliding movement therein with the proximal and distal ends of said wires extending from the ends of said conduits, the proximal ends of said wires being coupled to said foot pedal apparatus with the distal end of one of said wires connected to said closure member control lever through a first guide pin and the distal end of the other of said wires connected to said flush water control lever through a second guide pin for rotation of said control levers in said first direction upon tension applied to said wires in response to downward depression of said pedal apparatus, bias means for returning said closure member to the closed position and closing said flush water supply means upon release of said pedal apparatus by rotating said control levers in a second direction opposite to said first direction, said flexible control wires being solid element wires of sufficient stiffness whereby compression of said wires by manual raising of said foot pedal apparatus causes said control levers to rotate in a second direction in the event of a failure of said bias means.

Claim 3

Toilet apparatus according to claim 1 wherein said foot pedal apparatus comprises a pair of side-by-side foot pedal members, one of which is connected to said flush water control lever so that downward movement of said one pedal member results in rotation of the flush water control lever in said first direction causing supply of flush water to the bowl and the other pedal is connected to said closure member control lever so that downward movement of said other pedal member causes rotation of the closure member control lever in said first direction to move said closure member to said open position.

Claim 4

Toilet apparatus according to claim 2 wherein said foot pedal connected to said flush water control lever coacts with the pedal connected to the closure member control lever so that downward movement of the last mentioned pedal results in downward movement of the other pedal.

Claim 5

Toilet apparatus with foot pedal flush comprising a housing, a toilet bowl mounted on said housing and having an outlet at its lower end and a closure member movable between positions opening and closing said outlet, and flush water supply means including a discharge nozzle operatively associated with said bowl for supplying flush water to the upper end of the bowl, a closure member foot pedal pivotally mounted on said housing, a flush water foot pedal pivotally mounted on said housing, a closure member control lever and a flush water control lever both rotatably mounted to said housing about a common pivot, said closure member control lever being coupled to said closure member for moving said closure member to said open position in response to rotation of said closure member control lever in a first direction, said flush water control lever being coupled to said flush water supply means for operating said supply means to supply flush water to said bowl in response to rotation of said flush water control lever in said first direction, a pair of flexible control wires contained in conduits mounted to said housing for sliding movement therein with the proximal and distal ends of said wires extending from the ends of said conduits, the proximal ends of said wires being coupled to said foot pedals with the distal end of one of said wires being coupled to said closure member control lever through a first guide pin and the distal end of the other of said wires coupled to said flush water control lever through a second guide pin for rotation of said levers in said first direction upon tension applied to said wires in response to downward depression of said pedals, bias means for returning said closure member to the closed position and closing said flush water supply means upon release of said pedals by rotating said control levers in a second direction opposite to said first direction, said flexible control wires being solid element wires of sufficient stiffness whereby compression of said wires by manually raising said foot pedals causes said levers to rotate in said second direction in the event of failure of said bias means, said guide pins moving in an arcuate path formed by tracks in said housing in response to pulling by said wires, said arcuate path being eccentric about said pivot and said guide pins extending through slots formed in said closure member control lever and said flush water control lever along which slots said guide pins travel as said guide pins move through said arcuate path.

Claim 6

Toilet apparatus with foot pedal flush comprising a housing, a toilet bowl mounted on said housing and having an outlet at its lower end and a closure member movable between positions opening and closing said outlet, and flush water supply means including a discharge nozzle operatively associated with said bowl for supplying flush water to the upper end of the bowl, a closure member foot pedal pivotally mounted on said housing, a flush water foot pedal pivotally mounted on said housing, a closure member control lever and a flush water control lever both rotatably mounted to said housing about a common pivot, said closure member control lever being coupled to said closure member for moving said closure member to said open position in response to rotation of said closure member control lever in a first direction, said flush water control lever being coupled to said flush water supply means for operating said supply means to supply flush water to said bowl in response to rotation of said flush water control lever in said first direction, a pair of flexible control wires contained in conduits mounted to said housing for sliding movement therein with the proximal and distal ends of said wires extending from the ends of said conduits, the proximal ends of said wires being coupled to said foot pedals with the distal end of one of said wires being coupled to said closure member control lever through a first guide pin and the distal end of the other of said wires coupled to said flush water control lever through a second guide pin for rotation of said levers in said first direction upon tension applied to said wires in response to downward depression of said pedals, bias means for returning said closure member to the closed position and closing said flush water supply means upon release of said pedals by rotating said control levers in a second direction opposite to said first direction, said flexible control wires being solid element wires of sufficient stiffness whereby compression of said wires by manually raising said foot pedals causes said levers to rotate in said second direction in the event of failure of said bias means, said guide pins moving in an arcuate path formed by tracks in said housing in response to pulling by said wires, said arcuate path being eccentric about said pivot and said guide pins extending through slots formed in said closure member control lever and said flush water control lever along which slots said guide pins travel as said guide pins move through said arcuate path.
