Rotator cuff therapeutic exercise apparatus
First Claim
1. A therapeutic exercise apparatus, comprising:
- a frame;
at least one weight supported on said frame for movement along a working stroke from a rest position against gravitational force to a displaced position;
an actuator mechanism mounted on said frame and adapted to be gripped and rotated by a hand of a user, said actuator mechanism being positioned in either a first or second operating configurations for permitting a corresponding rotational working motion of the one of the user'"'"'s arm whose hand grips said mechanism;
means coupled to said frame and interconnecting said actuator mechanism and said weight for transmitting rotational motion of the arm of the user to said weight to move said weight along its working stroke;
said motion transmitting means including a two-piece cam assembly with replaceable cams for permitting progressive comparative resistance exercising tailored to particular exercises;
said cam assembly including a rotatable member mounted in said frame and having a central axis and a peripheral portion, a first elongated flexible motion transmitting member interconnected at one end to said actuator mechanism and attached at the other end to a location on said peripheral portion of said rotatable member such that as said rotatable member is rotated in one or the other of clockwise and counterclockwise directions by rotation of said actuator mechanism said first flexible motion transmitting member adjacent said other end thereof will wrap about or unwrap from said peripheral portion of said rotatable member, a second elongated flexible motion transmitting member interconnected at one end to said weight, extending to said rotatable member and attached at the other end to the periphery of said rotatable member, and a contour cam member having an eccentrically-configured peripheral portion and being removably mountable on said rotatable member at said one side thereof and disposed about said central axis thereof such that as said rotatable member is rotated in one or the other of clockwise and counterclockwise directions by rotation of said actuator mechanism said second flexible motion transmitting member adjacent said other end thereof will wrap about or unwrap from said peripheral portion of said cam member.

Abstract
A rotator cuff therapeutic exercise apparatus is provided which includes a stack of weights supported on a frame for movement along a working stroke from a rest position against gravitational force to a displaced position and an actuator mechanism on the frame adapted to be gripped and rotated by a hand of a user to move the weights along the working stroke. The actuator mechanism is positionable in either first or second configurations for permitting a corresponding rotational working motion of the one of the user'"'"'s arms whose hand grips the actuator mechanism. For transmitting the rotational motion of the user'"'"'s arm to move the weights, a ratchet-type mechanism is provided which is connected to the actuator mechanism and allows internal and external rotation of the arm and for accomplishing positive and negative work therewith. A two-piece cam assembly with replacable cams is provided which is connected between the weights and the ratchet mechanism for permitting progressive (comparative) resistance exercising tailored to particular exercises.
