Abstract:
1. A toilet overflow prevention device comprising: (a) an electromechanical actuation device; (b) said electromechanical actuation device being movable in the vertical dimension in response to an electronic signal; (c) said actuation device being rotatably fixed to a control rod associated with the fill valve of a conventional toilet filling system such that said control rod may be lifted up from a first normal operating position to a second inoperable position by the action of said actuation device; (d) a sensor; (e) an electronic link from said sensor to said electromechanical actuation device; (f) a logic means for converting reading signals generated by said sensor into control signals directed to said electromechanical actuation device according to a heuristic; (g) a latch mechanism; (h) said latch mechanism being shaped and tensioned so as to receive said control rod in said second inoperable position and retain said control rod in said second inoperable position until manually released; (i) said electromechanical activation device being a solenoid; (j) said latch mechanism comprising a spring-loaded pin positioned horizontally so as to engage with a hole in the rod of said solenoid when said solenoid is in a raised position; and (k) said spring-loaded pin being further positioned so as to be manually disengageable; whereby an imminent overflow in said toilet may be detected and averted by retaining the control rod in said second inoperable position and thereby forcing said fill valve into an off position regardless of water level.
