Wave generating apparatus for waterbeds

A wave generating device for waterbeds, comprising:

• a liquid filled mattress resting on a frame;
• a bottom surface on the mattress;
• a mattress supporting platform;
• an underside surface on the mattress supporting platform;
• a housing having top, bottom, and side walls, the housing being securely fastened to the underside surface;
• an undulation means for producing a first wave motion on a mattress of the waterbed, further comprising:
• an electric motor stationed within the housing;
• an output shaft on the electric motor;
• an eccentric camming member connected to the output shaft;
• an outer edge on the camming member;
• a guide wheel in rolling contact with the outer edge;
• a first rod mechanism attached at one end to the guide wheel;
• and
• a first convex shaped agitation pad attached to another end of the first rod mechanism, the first agitation pad in intimate abutment with the underside of the mattress;
• and
• the first agitation pad producing a repetitive, upward force orthogonal to the bottom surface of the mattress;
• a vibration means for producing a second wave motion on the mattress of the waterbed, further comprising:
• a vibration producing mechanism secured to the bottom wall of the housing;
• a second rod mechanism attached at one end to the vibration producing mechanism;
• and
• a second convex shaped agitation pad attached to another end of the second rod mechanism, the second agitation pad in intimate abutment with the underside of the mattress;
• and
• the second agitation pad producing a repetitive, lateral force which is substantially parallel the bottom surface of the mattress;
• a control panel for adjustably controlling the frequency of the undulation means and the vibration means, including a pair of control knobs each having a plurality of settings;
• and
• electrical wiring which connects the control panel to the housing.
