Abstract

Abstract A floor-mounted anchor unit for toilets comprising---in association with an upstanding sewer pipe riser set before placement of the floor---a horizontal annular toilet attachment flange on the floor adjacent and in register with such riser, a horizontal annular sub-flange surrounding the riser in spaced relation below the toilet attachment flange and engaged beneath a portion of the floor, and a plurality of vertical, circumferentially spaced screws connected in holding relation between said flanges radially outwardly of the riser; characterized by the toilet attachment flange being initially detached, and means including said screws temporarily assembled with the riser and supporting the sub-flange in position on said riser preparatory to placement of the floor thereabout and over the sub-flange, said means being removable at least in part and with the screws to then permit said connection of said screws between the toilet attachment flange and the sub-flange.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 158 words
In a floor-mounted anchor unit, for a toilet, which includes, in association with a floor, an annular, floor-supported, toilet attachment flange, there being a vertical sewer pipe riser disposed coaxially of the toilet attachment flange and extending upwardly therebelow, an annular, floor-engaging sub-flange concentrically surrounding the riser in spaced relation below the toilet attachment flange, and a plurality of vertical, circumferentially spaced screws connected in holding relation between the toilet attachment flange and sub-flange radially outwardly of the riser; the improvement characterized by the sub-flange including a cup-like shroud fixed on and depending from said sub-flange, and the shroud having a circular bottom opening through which the riser extends in matching frictional relation whereby the shroud positionally supports the sub-flange from the riser upon initial placement of such sub-flange on said riser, and the shroud being of a diameter such that said shroud encompasses, in protecting relation, lower end portions of the screws which project below the sub-flange.
Claim 2
Dependent Claim 158 words
In a floor-mounted anchor unit, for a toilet, which includes, in association with a floor, an annular, floor-supported, toilet attachment flange, there being a vertical sewer pipe riser disposed coaxially of the toilet attachment flange and extending upwardly therebelow, an annular, floor-engaging sub-flange concentrically surrounding the riser in spaced relation below the toilet attachment flange, and a plurality of vertical, circumferentially spaced screws connected in holding relation between the toilet attachment flange and sub-flange radially outwardly of the riser; the improvement characterized by the sub-flange including a cup-like shroud fixed on and depending from said sub-flange, and the shroud having a circular bottom opening through which the riser extends in matching frictional relation whereby the shroud positionally supports the sub-flange from the riser upon initial placement of such sub-flange on said riser, and the shroud being of a diameter such that said shroud encompasses, in protecting relation, lower end portions of the screws which project below the sub-flange.
Claim 3
Dependent Claim 99 words
In a floor-mounted anchor unit, as in claim 1, the further improvement characterized by the inclusion, in the unit after initial placement of the sub-flange and prior to connection of the screws between the toilet attachment flange and the sub-flange, of a removable collar upstanding from the sub-flange in spaced surrounding relation to the riser, and a removable top plate on the collar in closing relation to the upper end of said riser, the screws being connected between the top plate and sub-flange and extending in the space between the riser and said collar and protected by the latter.
