Bridge drain for showers
A bridge drain for a shower floor consists of two or more bridge support drains supporting cantilevers joined at their distal ends by a bridge deck supporting an overlying drain grate optionally accommodating tiles. The box of a linear drain is replace by a drainage surface floor below the surface of the shower floor, bounded by built up areas of the shower floor and any walls, and drained by the point drains provided by the bridge support drains. Advantages include provision of drainage to the very edge of shower entrances, increased flexibility of installation through only having to install point drains instead of box drain troughs, and increased flexibility of provision of an infinite variety of polygonal perimeter drains to ensure thorough drainage from the shower floor.
1 . A bridge drain fitting comprising:
two or more support point drains installed each in a hole in the drain surface floor in a lower cavity in the shower installation bounded by vertical barriers to water flow comprised by walls and built up portions of the shower floor the upper surfaces of said shower floor being sloped to drain to the lower drain surface floor and egress by gravity via the support point drains to the drainage system.
supporting cantilevers fitted to the top of said supports.
a bridge deck to support a grate of equal height to adjacent built up portions of the shower floor attached to the distal ends of two adjacent cantilevers.
2 . A water diverter fitting as claimed in claim 1 wherein the deck portion may be adjusted in length to accommodate a variety of bridge spans between the two point drains.
3 . A derivative water diverter fitting as claimed in claim 1 wherein said a single support supports a single grate to an equal height of the adjacent built up portions of the shower floor by cutting to length of a pipe connecting the drain and the grate.
