Abstract
Abstract A device for stimulating the circulation of blood in the feet and legs of a standing or seated person, which comprises a pair of treadles to receive the feet of a person when the calves of the legs are in substantially upright positions, such as in a normal standing or sitting position. The treadles are pivotally mounted and linked to drive means to impart a generally up and down oscillating movement thereto, whereby the movement is imparted to the feet in a manner so as to oscillate the feet about the ankle joints.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
A floor walker device for stimulating the circulation of blood in the feet and legs and alternately flexing and relaxing the leg muscles, comprising: A. a base member; B. a pair of spaced apart, generally U shaped brackets fixed to said base; C. a pair of foot treadles, the heel portion of each being fixed to a yoke member, pivotally connected within one of said U shaped brackets in the area of the ankle joint of a foot placed on said foot treadle; D. a motor mounted in said base; E. an eccentric driven from said motor; F. rocker bar means centrally, pivotally connected to a fixed bracket; G. a crank arm pivotally connecting between said eccentric and rocker bar means to sequentially rock the opposed ends of said rocker bar in up and down directions; H. engagement means between said opposed ends and the respective toe end portions of said foot treadles to transmit the up and down movement thereto, whereby said foot treadles are pivoted about said pivotal connections.
