Abstract:
1. A hands free toilet seat system for allowing a user to raise and lower a toilet seat in a sanitary and convenient manner comprising, in combination: a toilet bowl adapted to be supported on a recipient surface; said toilet bowl having an upper surface ( a toilet seat having an upper surface and a lower surface; said toilet seat further comprises a front ( a base plate positioned on the upper surface of said toilet bowl and adjacent to the rear ( an input shaft mounted on said rearward bearing assembly with a first gear disposed at an end of said input shaft, a second gear disposed at an opposite end of said input shaft, and an intermediate slip clutch mounted on said input shaft between the first and second gears for rotation there with about a first axis of rotation, wherein said intermediate slip clutch allows said toilet seat to remain lowered despite the force applied by said motor when the motor is activated while a user is on the toilet seat; an output shaft mounted on said forward bearing assembly; said output shaft extending through said cylindrical bore of said toilet seat from side to side; a third gear mounted on an end of said output shaft for rotation therewith about a second axis of rotation, said third gear further having a lifting arm coupled to said toilet seat for the raising and lowering of said toilet seat in response to the rotation of said third gear and said lifting arm; an intermediate shaft mounted on said central bearing assembly; a fourth gear mounted on said intermediate shaft for rotation therewith about a third axis of rotation, said fourth gear in direct driving contact with said second gear and said third gear; a drive assembly mounted on said base plate adjacent to said rearward bearing assembly; said drive assembly comprising a motor and a pinion directly coupled to said first gear, whereby activation of the motor drives the pinion which in turn rotates said first gear, said second gear, said fourth gear, and said third gear with said lifting arm to raise and lower said toilet seat; said drive assembly also including an activation subassembly which comprises a switch coupled to said motor to energize said motor for raising the toilet seat upon the activation of said switch; said drive assembly also including a logic subassembly which comprising a timer for lowering the toilet seat after a predetermined time following the energizing said motor through the activation of said switch.
