Abstract
Toilet flapper valves with multiple volume flush capability which can be quickly and easily installed to replace existing flapper valves in old or new toilets to give such toilets the capability of providing selectable amounts of flushing water.
Description

This invention relates to toilet flapper valves which can be installed as adaptor kits into existing toilets or installed as new equipment into new toilets to make such toilets capable of delivering a partial tank amount of water, or a full tank amount of water upon flushing activation.
Currently a number of types of dual water quantity toilet flushing devices are available, but only as new toilet installations with completely new internal mechanisms or by performing a complete rebuild of the internal mechanisms in an existing type of standard or regular toilet either of which can be expensive to the average homeowner. It is obvious that a simple and easy to install and operate mechanism is needed at a low cost to provide the necessary incentives to aid in conserving our limited supply of urban water.
It is a main object of this invention to provide several types of toilet flapper valves which are simple and easy to install and operate and provide a choice of at least two different volumes of water upon flushing a toilet in which these flapper valves are installed.
It is another object of this invention to provide several types of selectable water volume flapper valves which are adjustable as to water volume delivered and can be easily substituted for parts in existing toilets.
It is an additional object of this invention to provide several types of selectable flushing water volume flapper valves which can be easily installed as new equipment in new toilets.
The preferred embodiment of this Flushette invention is a two section flapper valve assembly, made of a flexible, resilient material, with the lower section (herein referred to as a flapper valve discharge tube riser) being tall and hollow and approximately half the height of the maximum amount of water in the toilet tank, with the said lower section pivoting or bending about a point on a clamp-on bracket attached onto a regular type overflow tube in a currently regular type toilet and acting as a flapper valve on a regular type discharge tube seat, and with an upper section consisting of a currently standard type flapper valve, sealing on the top of the flapper valve discharge tube riser lower section, with upper section arms attached to and pivoting or bending near the pivot point of the lower section arms, with either the upper flapper valve section being operated alone for a partial water volume flush or both the upper and lower flapper valve sections being operated together for a full water volume flush and with a counter balance float on the opposite end of the tall, hollow, flapper valve arms or with weight added to the front of the flapper valve discharge tube riser section to assist the flapper valve discharge tube riser section to seal firmly on its seat. An added, optional, feature is having the flapper valve discharge tube riser lower section, made to expand or contract, especially in its vertical dimension, to alter the proportion of water flushed in the partial and full flush operations, plus having the counter balance float also made to expand and contract to alter the downward pressure of the flapper valve discharge tube riser section on its seat on the top of the discharge tube.
Claims (6)
1. A dual flush flapper valve apparatus comprising; a lower hollow segment having an upper open top and an open bottom, said open bottom adapted to seal a valve seat of a known toilet discharge tube, an upper segment engaged with said open top of said lower segment, a clamp on pivot bracket adapted to receive and be clamped onto a standpipe of a known toilet discharge outlet, said upper segment being pivotally attached to said bracket to allow swinging movement of said upper and lower segments between a sealing and a non-sealing disposition with respect to said toilet discharge tube, said upper segment having an open top forming a valve seat adapted to receive a conventional flapper valve in sealing engagement therewith, an adjustable float cantilevered to said bracket on a side opposite to said upper and lower segments, said adjustable float comprising a lower portion adjustably attached to an upper portion, said bracket having pivot points thereon to accept pivot arms of a conventional flapper valve.
2. A dual flush toilet flapper valve as in claim 1 , having a pocket into which can be placed weights to help hold the flapper valve segments on the toilet discharge tube.
3. A dual flush flapper valve apparatus comprising:
a riser segment comprising a lower hollow segment having an upper open top and an open bottom, said open bottom adapted to seal a valve seat of a known toilet discharge tube and an upper segment engaged with said open top of said lower segment, said upper segment having an open top forming a valve seat adapted to receive a conventional flapper valve in sealing engagement therewith,
a clamp on pivot bracket adapted to receive and be clamped unto a standpipe of a known toilet discharge outlet, said upper segment being pivotally attached to said bracket to allow swinging movement of said upper and lower segments between a sealing and-non-sealing disposition with respect to said toilet discharge tube, said bracket having pivot points to accept pivot arms of said conventional flapper valve, and
an adjustable float cantilevered to said bracket on a side opposite to said upper and lower segments, said adjustable float comprising a lower portion adjustably attached to an upper portion.
4. A dual flush toilet flapper valve as in claim 3, having a pocket into which can be placed weights to help hold the flapper valve segments on the toilet discharge tube.
5. A dual flush toilet discharge valve apparatus as in claim 3, having an adjustable float cantilevered to said bracket on a side opposite to said riser segment, said adjustable float comprising a lower portion adjustably attached to an upper portion.
6. A dual flush toilet discharge valve apparatus as in claim 3, having a pocket into which can be placed weights to help hold the valve segments on the toilet discharge tube.
