The present invention relates to an exoskeleton interface apparatus that parallels human arm motion and is comprised of a serial assemblage of five powered linkages and joints based at a rigid support structure worn on the torso of the human subject. Such apparatus generates shoulder rotation using three orthogonal revolute joints mounted on serial linkages encompassing and intersecting at the anatomical glenohumeral joint. Elevation of the shoulder joint is articulated using a link member driven by a single revolute joint mounted in the torso structure. Passive adjustable linkages are used to match variation in anatomical forearm length, upper arm length, and scapula-to-glenohumeral radius. A plurality of integrated dc motor/harmonic drive transmission modules is co-located on adjoining linkages to power the joints. Force is exchanged with the human at the handgrip and elbow brace, and reacted to the torso structure via the base attachment. The present invention is applicable in particular to rehabilitation of the shoulder.

A multi-functional exercise apparatus for exercising arms, shoulders and trunk of a user. This exercise apparatus may include a stationary bicycle support platform and includes an upper body assembly which is movably engaged to and extended about the bicycle's seat mount. An arm-shoulder device is movably engaged to the upper body assembly. By providing such exercise apparatus, a user can move the upper body assembly with respect to the bicycle's seat mount to exercise the user's trunk while moving the arm-shoulder device to exercise the arms and shoulders. The user can independently or simultaneously rotate the bicycle's foot pedals with the user's legs to exercise the same for a more complete workout.

The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Elliptical cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical cross trainers often use excessive pedal articulation which can overwork the ankle to achieve a longer stride. The present invention is an improved elliptical exercise machine capable of extended exercise with less pedal articulation that is more ankle friendly. One end of a foot support member has a pedal which follows elliptical motion while the other end is guided by a non-aligned drive link to drive an alternator and flywheel. The resulting pedal motion is foot friendly. Handles are coordinated with the foot support members for arm exercise. Adjustment is provided for the elliptical path.

A chest press exercise machine has a self-aligning pivoting user support on a main frame and an exercise arm which is linked to the pivoting user support to translate movement of the exercise arm into movement of the user support. A user support pivot pivotally connects the user support to the main frame. A connecting link is movably associated with the user engagement device or exercise arm and at least one of the main frame, user support, or user support pivot. A user-activated positioning device controls positioning of the exercise arm in an exercise ready position at the start of an exercise. The user support pivot is positioned so that part of the combined weight of the user and user support is positioned on both sides of the gravitational centerline throughout the exercise movement and a portion of the combined weight passes through the centerline to redistribute the weight as the exercise arm is moved.

The rotatable push-up exercise device provides device for aiding a user in performing push-up type exercises. The device has a platform rotatably mounted on a base. The platform may selectively be held stationary or may be free to rotate when performing push-up exercises. The device includes a gripping bar mounted on the platform. The base is adapted to rest on a support surface, such as the floor. A pair of exercise devices are normally utilized together. In use the user grasps the gripping bar of each device with one hand and performs push-up exercises. Due to the rotation of the support surface with respect to the base, the user is forced to exercise the shoulders and other muscle groups in the user's body, in addition to the arm and chest muscles, in order to maintain a stable position.
