Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 379 words
A portable device for use on a toilet to dispose of waste material when operated by an animal trained to use it, said device including: a bottom wall, a back wall, two side walls, and a front wall forming a receptacle adapted to fit on said toilet; a central opening for disposal of the waste material into the toilet, said central opening formed in the back and bottom walls of said receptacle; said bottom wall being sloped toward said central opening; two mounds located on said bottom wall on opposite sides of said central opening; a front opening formed in said front wall; a plank having a first end and a second end, said first end of said plank being attached to said bottom wall at said front opening and extending outwardly from said receptacle, a set of steps, said second end of said plank being attached by a hinge to said set of steps; whereby said set of steps, said plank, and said front opening allow said animal to enter said receptacle; a flushing system including a power source, a timer, first and second solenoids, first and second valves actuated by said first and second solenoids, a reservoir vessel, a perforated tube, and a non-perforated tube connecting said reservoir vessel to said perforated tube via said first valve; said perforated tube being located on the top inner side of said front, back and side walls, said reservoir vessel containing water for flushing waste material from said receptacle; said second valve being associated with said toilet to flush said toilet; said plank having a sensor triggered by said animals' weight to start said flushing system; whereby actuation of said sensor by said animal causes said timer at a preselected time t 1 to activate said first solenoid which opens said first valve which allows water from the reservoir vessel through said non-perforated tube to said perforated tube to flush said waste material from said side and bottom walls into said central opening and to deactivate said first solenoid at a preselected time t 2 ; said timer at a preselected time t 3 activates said second solenoid which opens said second valve to flush said toilet and to deactivate said second solenoid at a preselected time t 4 .
