Patent ID: 8727950

Claim:
An armband exercise device for use while wearing a prosthesis for permitting exercise of an entire arm comprising: a four-sided sheet of leather of at least two plies or flexible and inelastic fabric having a first surface, a second surface, an upper edge, a lower edge, a first side edge and a second side edge wherein a length from the upper edge to the lower edge measured along a longitudinal axis is sized to be about equal to a length of a user's arm from shoulder to wrist; a first opening cut through the four-sided sheet, disposed and sized to accommodate an outer surface of an elbow joint when the device is wrapped around the user's arm; a second opening cut through the four-sided sheet, disposed and sized to accommodate an inner surface of an elbow joint to promote flexibility when the device is wrapped around the user's arm; a first strip of hook-and-loop fastener along the first side edge of the first surface and a second strip of hook-and-loop faster complementary to the first strip along the second side edge of the second surface with the first strip and the second strip interacting to hold the device in a wrapped position when the device is wrapped around the user's arm with the side edges overlapping; a plurality of cinching straps including hook-and-loop fastener, each strap extending from a fixed end attached to the four-sided sheet near the second side edge running perpendicular to the longitudinal axis of the four-sided sheet to a free end near the first side edge; a plurality of cinching rings, at least one per cinching strap, each ring attached to the device and disposed so that pulling the free end of each cinching strap through its respective cinching ring tightens the device when wrapped around the user's arm and the prosthesis with the hook-and-loop fastener on the cinching straps maintaining the device in a tightened state so that strength, inflexibility and tightness of the device reinforces connection with the prosthesis and prevents the prosthesis from being pulled off; and a plurality of attachment hardware attached to the device to enable pulling and lifting exercise as well as suspension and suspension training.
