Abstract: Thermoplastic multiple channel tubing, which includes at least a pair of channels separated by a partition, is bent into a desired shape or configuration by softening the tubing and then bending it into the desired shape or configuration. The tubing is pegged and clamped so as to maintain the shape of the clamped portion of the tubing, as well as the shape of the partition and its proper orientation with respect to the rest of the tubing, during the bending operation.
Abstract: A connector assembly is adapted to connect an outlet of a whirlpool system to air and water supply channels. Because the connector assembly is removably mounted to the air and water supply channels between the ends thereof, the air and water supply channels can be made from a continuous piece of tubing.
Abstract: A gasket assembly is provided for coupling the drainage outlet openings of a bathtub and of a plastic liner installed within the bathtub for renovating the latter. The gasket assembly includes a hollow cylindrical body inserted in the space between the bottom wall of the plastic liner and the bottom wall of the bathtub, and having flanges at its upper and lower ends for making sealed connections with the drainage outlet opening of the bathtub and the overlying outlet opening of the plastic liner. The gasket body is made of elastomeric material and has an accordion-pleated side wall so that it is stretchable and compressible and therefore adaptable to bathtub installations of differing sizes. One-way valve means are also provided on the gasket body for draining out water which may accumulate in the space between the plastic liner bottom wall and the bottom wall of the bathtub.
Abstract: A whirlpool system has a pair of channels which connect sources of water and air to a plurality of outlets in a water receptacle. Each of the channels is formed in a continuous piece of tubing which is connected to the outlets by a plurality of connector assemblies removably mounted to the tubing between the ends thereof. If the tubing is made from a thermoplastic material, the tubing may be inserted into a hot liquid bath and, after the thermoplastic material becomes sufficiently soft, bent into a desired shape or configuration.
Abstract: A combination liner assembly for bathtub, walls and ceiling is provided for renovating a worn or outmoded bathtub installed in a wall recess. The assembly includes a plastic bathtub-shaped liner having a tub portion sized to be seated in the tub cavity of the bathtub with the bottom surface of the tub portion resting upon the bottom surface of the original tub cavity and said bottom surface supporting the weight of the liner as well as the water and the bather therein. The bathtub liner is connected to the waste and overflow drains of the original bathtub and has an outwardly projecting peripheral flange around the top edge thereof which overlies the marginal ledges of the bathtub. Sealing membranes provide water-tight seals between the peripheral flange of the bathtub liner and the walls of the wall recess. The assembly also includes a matching wall liner which covers the walls of the recess above the bathtub liner. The wall liner may be topped by a dome, which rests on an outwardly-extending flange.
