ABSTRACT:
A wave generating device for waterbeds, including an undulation mechanism for producing a first wave motion on a mattress of a waterbed, with the first wave motion including a repetitive, upward force which is orthogonal to a bottom surface of the mattress. A vibration mechanism produces a second wave motion on the mattress of the waterbed, with the second wave motion including repetitive, lateral forces in substantially the same plane as the bottom surface of the mattress. There is a control mechanism for adjustably controlling the speed of both the undulation and, vibration mechanisms, along with a housing mechanism for containing them. Finally, there is a securing mechanism for attaching the housing mechanism to an underside surface of a mattress supporting platform in the waterbed, and wiring for electrically connecting the control mechanism to the housing mechanism.
