Physical conditioning and therapeutic conditioning pivoting system

Abstract

A physical conditioning and therapeutic conditioning system that, when configured and incorporated into the construction of a chair, has a seat, a base configured to rest on a surface, and a seat-support mechanism which is configured to couple the seat to the base and enables the seat, when unlocked in one embodiment, to be pivoted in any direction while rocking in the seat and using one's own body weight for resistance. Ideally the seat-support mechanism permits universal motion in all directions above a vertical axis, including front to back inflection and side-to-side inflection of at least 40° , including 360° of rotation on a universal type joint. The universal type joint is a ball joint consisting of a bearing stud and socket enclosed in a case, with all parts made of steel. In one embodiment, the bearing stud is tapered and fits into a hydraulic post. A ball joint is used to allow free rotation in two planes at the same time. The universal ball joint when attached to the underside of a seat is surrounded by a metal caste collar, also attached to the underside of the seat, and with a locking system attached to the upper collar. Inserted into the upper collar, along with a lower collar attached to the arm support structure, surrounding the ball joint assembly is a hardened metal coiled spring, used ideally to stabilize, through compression, the seat in a horizontal position and allow for locking the seat in a horizontal position, when no force is applied or when not in use.
