Abstract
A carrier body assembly for forming part or all of a shower floor includes a rigid carrier body having a bearing surface for sanitary surface material such as tile and a sealing membrane that overlies the top or bottom surface of the carrier body but is attached to only a portion of the top or bottom surface. The unattached portion of the membrane is folded away from the carrier body to enable trimming of the carrier body to fit without damaging the membrane. After installation of the carrier body the membrane overlies the adjacent shower structure to form a watertight, water-impermeable connection between the carrier body and the adjacent shower structure.
Claims24
A carrier body assembly for supporting a sanitary surface material, the carrier body assembly comprising:
- a rigid carrier body and a sealing membrane, the carrier body and the sealing membrane being transportable as a unit;
- the carrier body comprising an upper surface, a lower surface, and a drain opening extending through the carrier body from the upper surface to the lower surface;
- one of the said upper and lower surfaces comprising an inner surface portion, an outer surface portion surrounding the inner surface portion, and a peripheral edge defining the outer perimeter of the said one surface, the drain opening disposed in the inner surface portion of the said one surface;
- and
- the sealing membrane comprising an inner portion and a flexible pliant outer portion surrounding the inner portion, the inner portion being disposed on an outer side of the carrier body assembly and the outer portion having an exposed outer edge surrounding the outer portion, the inner portion permanently affixed to and covering said inner surface portion of the one surface of the carrier body, at least a portion of the outer portion of the sealing membrane not permanently affixed to the carrier body and foldable away from the carrier body along a non-predetermined fold line to and from a substantially flat condition along the fold line 90 degrees or more while maintaining the integrity of the sealing membrane, the outer portion overlappable with the outer surface portion of the one surface of the carrier body and extendable from said peripheral edge of the one surface beyond said peripheral edge and away from the other of the said upper and lower surfaces of the carrier body,
- whereby the carrier body assembly may be transported from a remote location to a job site and at least a portion of the outer portion of the sealing membrane can be folded away from the carrier body at the job site to enable trimming of the carrier body without damaging the sealing membrane and can be folded towards the carrier body to overlap and extend beyond the carrier body after trimming.
A transportable carrier body assembly for use in forming a shower foundation at a job site, the carrier body assembly comprising:
- a rigid carrier body and a sealing membrane attached to the carrier body, the carrier body and the sealing membrane being transportable as a unit;
- the carrier body comprising opposite first and second surfaces on opposite sides of the carrier body, a drain opening extending through the carrier body from the first surface to the second surface, the first surface comprising an outer peripheral edge that surrounds the first surface;
- the first surface comprising an inner surface portion and an outer surface portion surrounding the inner surface portion, the outer surface portion extending from the inner surface portion to the outer peripheral edge;
- and
- the sealing membrane comprising an inner membrane portion and an outer membrane portion surrounding the inner membrane portion, the inner membrane portion being disposed on an outer side of the carrier body assembly, the inner membrane portion covering and permanently fixed to the inner surface portion, the outer membrane portion extendable from the peripheral edge of the first surface outwardly beyond the peripheral edge and away from the second surface, and the outer membrane portion overlappable with the outer surface portion to cover the outer surface portion, at least a portion of the outer portion of the sealing membrane being foldable away from the carrier body at least 90 degrees while maintaining the integrity of the sealing membrane,
- whereby the carrier body assembly may be transported from a remote location to the job site and at least a portion of the outer membrane portion can be folded away from the outer surface portion at the job site to enable trimming of the outer surface portion without damaging the sealing membrane.
