Integrally formed water and space saving lavatory-toilet fixture

摘要

This integrally formed water and space saving lavatory-toilet fixture enables hand washing with potable water from an existing toilet, recycles effluent completely, and provides sanitary, seamless, one-piece, full perimeter tank closure. A flexible hose re-directs supply away from the overflow through an interior fixture cavity and top cast opening toward a basin, that drains back into the reservoir as effluent; supplementing the required volume of water to complete one flush cycle. A cast sidewall basin opening is formed allowing potential drainage to flow through an internal hollow cavity directly into the tank reservoir below. The integrally formed fixture also includes a sloped front wall allowing additional hand washing space, vertically aligned space saving side and rear walls, and, an integrally formed perimeter rim conforming to the shape of the toilet tank edging below, providing hygienic, continuous tank containment and secure, detachable mounting.

主权项

1. An integrally formed water and space saving lavatory fixture for use in combination with a gravity flow toilet, said toilet having a bowl and a flush tank, said flush tank having integrally cast front, back, bottom and side walls, together forming a reservoir, a flush mechanism controlling a bottom reservoir outlet valve, said outlet integrally formed as a unit with an overflow pipe assembly, said valve and said assembly independently in flow communication with said bowl, a reservoir water supply pipe, and a float actuated valve having an supply inlet port in flow communication with a basin hose connected thereto, said hose allowing fluid conduit passage there through from said port through said fixture by providing potable water flow from said supply to said fixture, said float valve opening in response to said mechanism opening said reservoir valve, said supply providing potable water to said reservoir and said port until said float valve closes when a predetermined volume of water is re-established in said reservoir, and, said tank walls defining a perimeter top edge rim providing support whereon the improvement is mounted above said tank and comprises:
An integrally formed shell, basin, and rim closure, said rim closure having a bottom perimeter portion aligning with said tank edge providing secure, detachable, direct, continuous and sanitary mounting of said rim closure on said tank edge, said rim closure projects over said top edge rim and overlaps said front and said side walls of said tank thereby extending below said top edge rim, said shell having back, side and lower front section walls straight and vertically aligned with said tank walls, a forwardly sloped upper section front wall, angularly oriented to said vertical lower front shell wall, said upper front wall projecting both upward and outward beyond the front tank wall whereby additional space to perform hand washing is created, altogether increasing the usable interior hand wash area of said fixture, and, top side, flat shell surfaces having an integrally cast opening therein, said basin including front, back and side walls including and overflow opening integrally cast in said basin sidewall allowing overflow water to drain from said basin through said opening into said reservoir below, a sloped bottom having a drain opening and drain pipe mounted therein for draining effluent from said basin through said drain opening and said pipe into said reservoir supplementing said volume necessary to establish said predetermined volume, said basin sidewalls opposing said shell sidewalls, together forming hollow interior cavities in the space located between said walls permitting fluid conduit passage there through from said side overflow and said top cast opening through said cavity into said reservoir, said cavity and said top cast opening together providing conduit passage enabling said basin filler hose connected to said port to pass through said cavity and said top cast opening for supplying synchronized, continuous potable water flow there through from the discharge end of said hose into said basin when said float valve is open.
