ABSTRACT:
A wave generator for waterbeds comprises a paddle unit adapted for positioning on the horizontal mattress supporting surface of the bed frame between an edge of the mattress and a side panel of the frame and has a paddle extending to overlie the upfacing surface of the mattress. A pivoted arm supports the paddle and is reciprocated by an electric motor through pitman-like linkages to oscillate from a raised horizontal position to a downwardly inclined position whereby the paddle rhythmically depresses and releases the mattress creating waves in the surface thereof radiating from the paddle. A control box having an on/off switch, a speed control for the motor and a timer for the switch is interposed along wiring from the motor. The length of wiring between the motor and control box being sufficient to locate the control box for easy access by a user reclining on the mattress when the paddle unit is in operative position.
