Cantilever Drain Top.

Abstract

The present invention is directed to methods of installation and use of drain and drain concealment structures. The preferred embodiment involves a method of installing and using a mortar drain base, threaded invertible membrane clamp, threaded flanged pipe, and drain cover when installed in a handmade mortared shower bed, or using a threaded pan drain base, threaded flanged pipe, and drain cover when installed on a prefabricated shower pan. The drain body may be connected to the shower bed or shower pan by any suitable means, such as but not by way of limitation by being integrally molded therewith during the manufacture of the pan, by connection post-manufacture, or in situ in the field. The cover, which is defined by a peripheral edge supported by horizontal cantilevered posts, is adapted to lie in registry with, and thereby cover, the drain aperture perforating the threaded flanged pipe. In this way, water is permitted to exit the shower or bath without the drain aperture being visible. Interchangeable drain covers may be used to effect aesthetic or functional objectives.

AI Technical Summary

Benefits of technology

The patent is about a way to prevent water from leaking through the floor of a shower made from mortar and tiles. It suggests using a special membrane that is secured with a clamp. The clamp is attached to the shower bed and a flanged pipe is inserted into the clamp to allow water to flow. The clamp has a cover to prevent water from leaking out. This invention helps to keep the shower floor dry and helps to maintain the quality of the tiled shower.

Problems solved by technology

Breda's design is particularly unsuitable for prefabricated shower pans, said design requiring a custom recess to be formed into the shower pan, both in diameter and depth.

Cook's utility is severely limited in application, requiring both specialized drain pans and providing no adjustability for the final height of the mortar bed and flooring comprising a mortared shower drain bed.
