Abstract:
1. A moving platform system, comprising: A) a base assembly anchored to a supporting surface; B) elongated structural means having first and second ends, said first ends being mounted to said base assembly: C) a bifurcated arms assembly mounted to said second ends, said bifurcated arms assembly including first and second arms extending outwardly with distal arm ends with each including bearing means; D) a cross bar assembly with first, second, third and fourth legs, each having distal leg ends, and said first and second legs being coaxially aligned, with their respective distal legs being rotably mounted to said bearing means thereby permitting said cross bar assembly to partially rotate about a longitudinal axis defined by said coaxially aligned first and second legs; E) platform means pivotally mounted to said distal leg ends of said third and fourth legs thereby permitting said platform means to partially rotate about a transversal axis defined by said coaxially aligned third and fourth legs and said transversal axis dividing said platform in first and second portions; F) means for imparting two periodic reciprocating movements with different frequency to two different offcentered points located on said first portion on said platform means thereby providing a periodic continuous movement to said platform means wherein said means for imparting at least two periodic reciprocating movements includes at least two wheels with linking arms having first and second ends pivotally mounted to said wheels and said platform means and electric motor means to provide rotational movement to said wheels wherein the speed of said linking arms can be independently varied by changing the position of the pivoting connection to said wheels; and G) adjustable counterweight means mounted to said platform at predetermined positions.
