Abstract
Abstract A foot pedal actuated attachment kit for urinal and commode flush valves features a closed hydraulic system interconnecting the valve element to be unseated and the foot pedal operator. The device is characterized by simplicity of construction and ease of installation on new or existing plumbing fixtures. The device offers the advantage of sanitation through lessening the spread of disease transmitted by the hands.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A foot-operated mechanism for actuating a toilet fixture flush valve having a stem which musT be tilted to release flushing water into the fixture, said mechanism comprising a cylinder piston unit on said valve including a reciprocating element adapted to engage and tilt said stem and a return spring for the reciprocating element, a foot pedal operated cylinder piston unit mounted near the floor and including a foot pedal extension for activating the piston of the second-named cylinder piston unit, a fluid conduit means interconnecting the first and second cylinder piston units, and a body of liquid within the cylinders of said units in opposing relation to the pistons therein so that movement of the piston in the second-named unit will cause a like movement of the piston in the first-named unit.
Claim 2
Dependent Claim
132 words
A foot-operated mechanism for actuating a toilet fixture flush valve having a stem which musT be tilted to release flushing water into the fixture, said mechanism comprising a cylinder piston unit on said valve including a reciprocating element adapted to engage and tilt said stem and a return spring for the reciprocating element, a foot pedal operated cylinder piston unit mounted near the floor and including a foot pedal extension for activating the piston of the second-named cylinder piston unit, a fluid conduit means interconnecting the first and second cylinder piston units, and a body of liquid within the cylinders of said units in opposing relation to the pistons therein so that movement of the piston in the second-named unit will cause a like movement of the piston in the first-named unit.
Claim 3
Dependent Claim
47 words
The structure as defined in claim 1, and a support for the second-named cylinder piston unit adapted to be mounted on a floor, a foot pedal pivoted to said support, and a linkage means interconnecting the foot pedal and the piston of the second-named cylinder piston unit.
Claim 4
Dependent Claim
33 words
The structure as defined in claim 1, and said fluid conduit means comprising a tube interconnecting said first named and second named cylinder piston units and having a fluidtight connection with each unit.
Claim 5
Dependent Claim
36 words
The structure as defined in claim 2, and said support comprising a boxlike housing substantially enclosing and concealing the second named cylinder piston unit and having an opening through which said foot pedal projects for use.
Claim 6
Dependent Claim
31 words
The structure as defined in claim 4, and a positive stop element on said foot pedal engageable with the floor to protect the foot pedal and associated linkage from excessive force.
Claim 7
Dependent Claim
58 words
The structure as defined in claim 1, and said first named cylinder piston unit including a cylinder body having a flange adapted to abut the end face of a tubular extension on the flush valve, and a coupling nut carried by said extension and engaging said flange and serving to firmly couple the same to said end face.
Claim 8
Dependent Claim
60 words
The structure as defined in claim 2, and said linkage means comprising a crank arm integral with said foot pedal and projecting laterally therefrom, the foot pedal pivot being offset from the axis of the piston of said second named unit, and a drive link pivotally interconnecting the rod of said piston and the crank arm of the foot pedal.
Claim 9
Dependent Claim
44 words
The structure as defined in claim 4, and the second named cylinder piston unit having a cylinder body including a flange, and means firmly attaching said flange to a wall of said boxlike housing so that the cylinder body is supported on said wall.
