Abstract
Abstract A portable miniature waterfall formed of an appropriate water resistant plastic and having a solid base provided with an upwardly directed cavity for holding a liquid such as water. The waterfall includes a simulated rock formation mounted on and extending upwardly from the base. The rock formation is hollow and includes an internal water circulating pump connected by a hose to the upper end of the rock formation for a discharge of pumped water which in turn cascades down the rock formation for recirculation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
A portable miniature waterfall comprising a portable unitary base provided with a shallow liquid holding basin formed therein, a simulated rock formation carried within and extending upwardly from said basin, said simulated rock formation being of cast plastic or resin and having a plurality of simulated rock-surface levels to allow liquid to cascade over said rock-surface levels and being formed to cooperate with said basin to define an interior chamber, a pump positioned in said chamber to receive water from said basin, and a conduit connecting the pump with an elevated position in said rock formation for elevating liquid from the basin to a discharge opening in the rock formation from which the liquid may cascade back over said levels into the basin.
Claim 2
Dependent Claim
