DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to sanitary fixtures such as commodes, toilets, water closets, bidets, sinks, wash basins, urinals and drinking water fountains and more particularly such fixtures made from interconnecting shells that include at least an inner shell and an outer shell and wherein the inner shell is supported providing structural integrity for the fixture. Fixtures of the present invention can be constructed from a number of interconnecting shell sections which themselves can be formed from any suitable material such as a plastics material, or various combinations or sub-combinations of a plastics material, ceramic or metal.
BACKGROUND OF INVENTION
Monolithic heavy-walled sanitary fixtures are well known in the art. Garnett in U.S. Pat. No. 3,843,977 issued Oct. 29, 1974 when disclosing his sanitary fixtures constructed from a plurality of plastic "shell" sections, discusses in some detail the inherent difficulties when constructing and designing sanitary fixtures made from ceramic materials, and the advantages gained therefore by producing a similar fixture constructed from a plurality of interconnected plastic shell sections.
The fixture as disclosed by Garnett employs an inner bowl or basin which is connected to a water trap. A two part rim member is used for discharging rinse water into the bowl or basin. The rim member is also connected to a base, wall or skirt element which exteriorly surrounds and obstructs the underside of the basin and water trap from view.
The various above described relatively thin-walled shell sections are interconnected providing an inner shell and an outer shell spaced apart so as to provide an internal cavity. When the fixture is inverted, this internal cavity is open at the top readily permitting pouring in a settable filler.
In order to structurally permanently interconnect the various shell sections, and in order to support same, Garnett teaches one to charge the internal cavity with a core material, such as water curing concretes and cements, or structural foam materials.
Because the internal cavity of the fixture must be filled for structural integrity and support, the "shell" fixture as disclosed by Garnett, given the inclusion of core material, and notwithstanding one of his intended objects, still remains undesirably heavy. Further, since the core material is required for structural integrity and support, its presence inhibits or restricts one's ability or freedom to create novel design or appearance features and include them in the area of the base or skirt section of the fixture.
Neither the Garnett type of "shell" fixture, nor the well known ceramic fixtures, are capable of having their external appearance features changed after assembly or fabrication. Additionally, while the colour of an existing sanitary fixture may be changed by painting, this is not normally regarded as practical or suitable by decorators, and when redecorating, it is not uncommon for one to replace the entire fixture with one displaying a new colour or new overall design, or both.
In German Patent Specification DE-A-23 43 615 which was laid open for inspection on Mar. 13, 1975, the plastic toilet bowl fixture therein disclosed comprises a metal frame, which is horseshoe shaped, and which is attached to a floor. A plastic pedestal part, at its lower end is supported by the sidewalls of the frame, and at its upper end, receives a plastic bowl section. The pedestal and bowl are interconnected under tension by means of a leaf spring extending across the frame and a screw and an adjustment nut arrangement that connects the bowl to the leaf spring. As disclosed, the greatest mechanical stress imparted to the fixture is experienced when the front or leading edge of the bowl is subjected to heavy loading. In order to prevent large stresses between the pedestal and bowl at this point, provision for relative motion or shifting between the pedestal and the bowl at their point of contact is disclosed, and is considered necessary in order for the neighbouring zones to take up
