Patent ID: 7780583

Claim:
An exercise device comprising: an adjustably resistive pivoting flexure joint assembly comprising at least one airspring assembly having at least one elastomeric bellows intermediate portion with a closed lower plate portion and a closed upper plate portion, both said closed lower plate portion and said closed upper plate portion being mechanically clamped directly to respective ends of said at least one elastomeric bellows intermediate portion, a lever arm having one end thereof attached directly to the closed upper plate portion of the flexure joint assembly, wherein said at least one elastomeric bellows intermediate portion serves as means for deflecting said lever arm at a variable resistance from a rest position to about 90° of deflection and rotating said lever arm at 360° of rotation, means for attaching said closed lower plate portion to a working/anchoring member or surface wherein said closed lower plate portion is configured to remain rigid and not move when said elastomeric bellows intermediate portion, closed upper plate portion and lever arm move, a human interface member removably connected to said lever arm; wherein a combination of said human interface member, and said lever arm and said flexure joint assembly is configured to provide ergonomically resistive non-striking therapy for a desired body part; and said lever arm further comprising means for adjustably and selectively pressurizing the flexure joint assembly using hand pumping means for manually pumping air into said flexure joint assembly, said hand pumping means being integrated within said lever arm and connected to said human interface member, which facilitates said manual pumping of air; and wherein said flexure joint assembly when pressurized at a selected desired resistance is configured to maintain a stored energy level such that an applied force must be exerted by a person to displace said lever arm from a neutral position and said force must be maintained to resist said lever arm's movement back to said neutral position.
