US 5,073,995 A · Universal toilet tank water saving device

Abstract

A water saving device for a flush tank includes a floating body, a guide track on which the floating body is slidably mounted by a bracket, and a clip mounted to the guide track for snap fitting around a standpipe of the tank. The guide track is positioned so that the body is substantially directly above a flush valve of the tank, so that upon flushing the body will contact and forcibly close the flush valve to save water. The weight of the body is adjustable, as the body has an inner chamber for holding ballast and an inlet sealed by a removable plug. The guide track has breakoff segments at its bottom portion so that the track can be adapted to virtually any size tank. In another embodiment of the water saving device, the guide track is replaced by a small diameter tube through which the chain linking the flush valve and the flush lever attached to a flush handle is threaded. The body has a large tube attached to it which slidably fits over the standpipe.

Dependent claims

In a flush tank containing water and having an outlet valve with a normally closed valve cover to maintain a normal water level, a handle for opening the valve cover to release water from the tank, a vertical standpipe with a lower end adjacent the valve cover and an upper end at least at a normal water level, wherein the valve cover closes in response to a decrease in water level to a minimum, the improvement comprising:

a floating body;
an elongate guide track having a T-shaped section, the T-shaped section being defined by a stem and a cross member;
means for fixedly attaching an upper end of the guide track to the standpipe;
and
means for slidably attaching the floating body around the cross member of the T-shaped section of the guide track,
wherein the guide track is disposes with its lower end adjacent the valve cover such that the body is positioned over the valve cover, whereby, in response to release of water, the body slides down the guide track and contacts the valve cover to thereby close the valve cover at an intermediate water level between the water level minimum and the normal water level.
