Abstract
Abstract A lavatory made of single molded plastic sheet with reinforcing on its underside is shaped to have a substantially flat counter portion, an upwardly rising back wall along the rear of the counter portion, a bowl rimmed by the counter portion, and a spout shaped fixture portion located between the back wall and the bowl. The fixture has a pair of spaced side walls rising up from the counter portion and extending forward from the back wall, a top side spanning between the side walls, and an underside which rises from the rear wall of the bowl in an arch to extend out over the bowl and join with the side walls and top to form the spout. A valve is mounted on the top side of the fixture portion.

Claim 1
Independent Claim
282 words
In an integral lavatory-fixture combination molded of a single plastic sheet with reinforcing along the under surface of the sheet, the lavatory portion having: a. a substantially flat counter portion; b. an upwardly rising back wall along the rear of said counter portion; and c. a bowl rimmed by and receding downward from the counter portion which has a rear wall region spaced forward of said back wall; the combination therewith of a hollow fixture portion located in the space between said back wall and bowl rear wall region, which fixture portion has: d. a pair of spaced side walls rising up from and integral with said counter portion, said side walls converging with said counter portion with large radius curves, said side walls also extending forward from and being integral with said back wall and converging therewith with large radius curves; e. a top side bridging between said side walls, forming a valve pedestal, and extending forward from said back wall which is an integral continuation of all said walls; f. an underside which is integral with and rises from said rear wall of said bowl in an arch that extends out over the bowl to overhang plastic sheet material forming said bowl rear wall region, and which joins with and is integral with each of said side walls to form, with said side walls and said top side, a hollow spout closed on its top, bottom and sides from the single sheet of molded plastic material that overhangs said bowl; g. an outlet pipe and nozzle mounted within said spout; and h. a mixing valve on said pedestal having a portion inside the fixture portion connected with said outlet pipe.
