摘要

A footrest which is adapted to be used by a person for exercise, enjoyment and relaxation. The footrest included an arcuate upper surface for contact by the feet of the user and motion enabling means for allowing the user to move the footrest virtually omnidirectionally. The footrest incorporates a mechanism to ground the unit if excessive force is applied to it exceeding a preselected amount. The grounding mechanism includes preloaded compressed springs which allow one element of the footrest to inhibit the motion enabling means upon application of a preselected force or a given displacement.
