Exercise Rocking Chair

摘要

A rocking chair provides abdominal exercise by user actuation of pivotal armrest handles that are configured to provide a crunch type exercise motion. The arrangement of internal pivot frames is such that armrest handle actuation shifts the user's center of mass both vertically and longitudinally, which in turn initiates a natural rocking motion by gravity. The inertial dynamics of the resulting motion are inherently kinesthetically pleasurable. The resistance is provided by the user's own body weight with variation through differential leverage. Alternatively, the configuration of the armrest handles is such that a user may benefit from an isometric exercise by simply holding them stationary in a conventional armrest position.

主权项

1. In an exercise chair, the combination comprising
a lower rocker base with an arcuate floor contacting surface that rocks on a floor in a vertical longitudinal plane; an upper seat in which a user may sit facing in a forward longitudinal direction; a set of one or more transverse support frames whose lower portions pivotably connect to said rocker base about transverse axes and whose upper portions pivotably connect to said seat about transverse axes; a set of left hand and right hand user actuator handles whose end portions connect through an actuator frame that pivotably connects to said rocker base about a transverse axis; and an actuation linkage by which user movement of said handles causes said seat to move both vertically and horizontally with respect to said rocker base.
