DUAL FLUSH MECHANISM FOR WALL-MOUNTED TOILET TANKS

Claims

Dual-flush mechanism for toilet tanks, configured to offer two flush volumes via a manual actuation structured in two variants. In the first, two articulated levers share an adjustable shaft integrated into the front cover. One lever is quarter-circle shaped and features a curved groove to guide a flexible cable that connects to the valve. The other lever, with a break and a pin at its inner end, slides within the groove of the first lever, defining a shorter stroke for partial flushing. In the second variant, two independent buttons protrude from the cover, each associated with an internal articulated piece that converges on a rigid connecting bar, facilitating connection to the valve. One button has a shorter stroke, ensuring a partial flush, while the other allows for a full flush.In both versions, a pulley mounted on an adjustable bracket attached to the lid ensures the vertical guidance of a cable or rope, preventing deviations and guaranteeing the correct closure of the valve. This provides a robust and adaptable structural system that optimizes water consumption and reduces losses due to faulty seals.
