  • Patent number: 5611093
    Abstract: A multi-lavatory system is preassembled to facilitate efficient installation with a minimum of connection points. The multi-lavatory system is connected to a single fluid supply line and a single drainage line. A fluid supply network conducts water from the single fluid supply line to a plurality of lavatory stations. Similarly, a drainage network conducts waste water from the plurality of lavatory stations to the single drainage line. Additionally, the multi-lavatory system includes a unitary lavatory subassembly having interconnected but spaced sink regions. Each sink region is disposed in one of the lavatory stations and is bounded at a frontal area by an upstanding contoured wall that creates an independent washing zone. This facilitates efficient production of the unitary lavatory subassembly and overall multi-lavatory system while providing each user of the system with a sense of privacy in their own independent washing zone.

  • Patent number: 4624020
    Abstract: To provide for positive sanitary separation of water spilling or overflowing from a washing sink unit (1), a cleaning sink unit (2) and a third water receiving unit (3), which may be formed as a sink unit or as a drain board, the second unit, located between the first and the third, is surrounded by a raised zone which merges with a forward region of a water retention rim (4) surrounding all the sink units, the raised region (5) terminating short of the rear edge region (19) of the sink unit, and leaving with the water retention rim (4) adjacent the rear edge region a gap (7). A drain and overflow opening (8) is located in the gap. Surfaces of the sink which may be essentially planar are pitched towards the overflow and drain opening, so that any water splashing or overflowing from any one of the three units or regions (1, 2, 3) will drain off into the overflow without flowing back into another one of the units or regions.
