Toilet flapper valve with adjustable mounts and assembly
An improved toilet flapper valve is used to cover and seal a main flush valve orifice, which flapper valve comprises a pair of rotatable legs and leg clips having two-way adjustment capabilities and which serve to function as mounting arms. The two-way adjustment of the rotatable leg clips allows for use of the same flapper valve with a variety of makes and models of flush valves, and flush valves having pegs that may be spaced apart so as to adjust for pegs that may have different diameters or that may be separated from one another by different distances depending on the flush valve used in the toilet. The flapper valve of the present invention also includes a variably-adjustable air outlet capability.
1. A toilet flapper valve comprising:
a flapper body comprising a generally circular forward portion and a pair of leg clip mounting structures disposed rearwardly of the generally circular forward portion, the leg clip mounting structures further comprising a rearward flat and a generally frustoconical retainer; and
a pair of leg clips each comprising a mounting leg comprising a forward facing flat having an aperture, the aperture being sized sufficiently to accommodate the frustoconical retainer to secure the leg clip mounting structures of the flapper body and a clip portion, the clip portion comprising a first clip member and a second clip member, the first and second leg clips attachable to the leg clip mounting structures and wherein the leg clips are rotatable about the frustoconical retainer from a first position in which the clip portions are relatively closer to one another to a second position wherein the clip portions are relatively farther apart.
2. The toilet flapper valve of claim 1 wherein the generally frustoconical retainer further comprises a peripheral groove that is disposed immediately adjacent the rearward flat of the leg clip mounting structure.
3. The toilet flapper valve of claim 1 wherein the leg clip mounting structures further comprise a plurality of support ribs extending forwardly from the leg clip mounting structures.
4. The toilet flapper valve of claim 1 wherein the frustoconical retainer is resiliently compressed so as to permit the frustoconical retainer to be inserted through the aperture in the leg clip up to a peripheral groove adjacent the rearward flat of the leg clip mounting structure.
5. The toilet flapper valve of claim 1 wherein the flapper body further comprises a cone disposed below the flapper body and a rotating vent band disposed below the flapper body and about the cone.
6. The toilet flapper valve of claim 1 wherein the flapper body further comprises a rubber material having a chemical resistant chlorazone additive.
