The failure of toilet flappers to properly seal toilet tanks wastes a tremendous amount of water, often going undetected indefinitely. Water conservation is a critical global obligation. This invention controls the water supply to a toilet via an interconnect from the flush handle to a mechanical style water supply timer thereby preventing toilet systems from wasting water during an adverse system state.
Invention is a toilet water supply control system which integrates a mechanical style water supply timer at the point of water supply entry in a toilet tank with an actuation interconnect from the toilet flush handle to the mechanical style water supply timer. The timer is actuated by flushing the toilet thereby causing opening of the water supply valve for only the time requisite to fill the tank once. The timer will shunt the water supply upon attaining the time requisite to fill the tank regardless of system state thereby preventing supply water run-on normally associated with a system defect whether a system defect occurs during the flush/fill cycle or during any infinite time thereafter.
Invention is a toilet water supply control system which prevents failing toilet components from wasting water by controlling the water supply via a mechanical style timer, which upon flushing the toilet, only allows water to flow into the tank for the time requisite to fill the tank. Invention prevents wasting of water whether toilet system fails during the flush/fill cycle or during any infinite time thereafter. Only the action of flushing the toilet allows the mechanical style water supply timer to open the water supply valve for the time requisite to fill the tank.
Invention is made by integrating a mechanical style water supply timer into a conventional load control device in a toilet. A crank handle is attached to the mechanical style water supply timer and interconnected to the toilet flush assembly. The toilet flush assembly is custom made to provide for multiple interconnects while providing for a maximum operating force not exceeding five pounds force (22.2 Newtons) by utilizing offsetting counterweight.
Invention is made by installing a riser from the toilet water supply inlet to the inlet on a mechanical style water supply timer. Another riser extends from the outlet of the mechanical style water supply timer to the inlet of the conventional load control device in a toilet.
The crank handle is fabricated from a 3.275″ long piece of 0.3125″×0.0938″ extruded aluminum. It has two 0.0469″ radius mounting holes spaced 1.25″ apart beginning 0.1″ on center from the first end. It has three 0.025″ radius interconnect holes at 0.5″ spacing along the centerline beginning 0.5″ from the second end. It is attached to the mechanical style water supply timer and interconnected to the toilet flush assembly by a 0.25″ wide stainless steel chain.
The flush assembly consists of a flush handle, a flush arm, a flush assembly threaded sleeve, and a flush assembly nut.
The flush handle is 1.375″×3.0175″ overall, manufactured from cast aluminum, polished to a high sheen, and features a counterweight cavity accessible from the back. Mass is added to the counterweight cavity as necessary to calibrate the magnitude of force requisite to flush the toilet while concurrently activating the timer based on the force requisite to perform the sum of the operations which has been demonstrated to vary among different timers.
The flush arm is manufactured from a 11.5404 inches long piece of 0.3125″×0.0938″ extruded aluminum with 0.0625″ radius interconnect holes through the wide face thereof spaced 0.6250″ apart along the centerline commencing 0.6508″ inches from the terminus and concluding at the tenth hole.
The flush assembly threaded sleeve is manufactured from injection molded polyvinylchloride.
The flush assembly nut is manufactured from injection molded polyvinylchloride.
The flush assembly subassembly is made by pressing the flush handle under force a distance of 0.75″ into the flush arm, thence sliding the flush assembly threaded sleeve along the flush arm to the flush handle, and finally bending the flush arm ninety degrees at a point 9.5716 inches from the end thereof.
The final assembly of the flush assembly occurs at time of installation in a toilet tank by inserting the flush assembly subassembly through the industry standard hole in the tank wall, aligning the flush assembly threaded sleeve with the industry standard hole in the tank wall, sliding the flush assembly nut along the flush arm and securing the flush assembly nut to the flush assembly threaded sleeve.
Invention is used by flushing the toilet. Actuation of the toilet flush handle trips an interconnect to a mechanical style water supply timer which opens the water supply valve for only the time requisite to fill the tank. Upon passage of time requisite to fill the tank, the water supply closes and will not open again until a user subsequently actuates the flush handle. User is unaware of invention's presence and function under normal operating conditions.
If an adverse system state including but not limited to failure of the flapper to properly seal the tank arises during the flush/fill process, the system will prohibit supply water run-on by closing the water supply valve upon passage of time requisite to fill the tank regardless of whether any water was retained in the tank. A user will identify the system defect the next time they attempt to flush the toilet because when they activate the flush handle, the toilet will not flush, but water will again begin to flow into the toilet tank because of the interconnect from the flush handle to the water supply timer. This allows the water to enter the tank to allow the toilet to be flushed and informs the user to repair the system.
If an adverse system state arises during any infinite time after the flush/fill process has completed, the system will be protected from wasting water because only the actuation of the flush handle will allow supply water to enter the system. A user will identify the system defect the next time they attempt to flush the toilet because when they activate the flush handle, the toilet will not flush but water will begin to flow into the toilet tank because of the interconnect from the flush handle to the water supply timer. This allows the water to enter the tank to allow the toilet to be flushed and informs the user to repair the system.
