An adjustable rehabilitation and exercise device, including a rotary member rotatable on a hub and having a plurality of elongated and spaced apart elongated mount receivers defined thereon; a mount selectively and movably positionable on a selected one of the mount receivers of the rotary member to select an angular location of the mount, the mount including a sliding member movably positionable along the selected mount receiver to a selected radial location along the selected mount receiver to select a radial location of the mount relative to the hub; and a patient engagement member connectable to the mount and movable with the mount.

An adjustable rehabilitation and exercise device, including a first rotary member rotatably mountable about a first hub and having a plurality of spaced apart and elongated first mount supports defined thereon; a first mount adjustably positioned on one of the first mount supports; a first patient engagement member attached to the first mount, a second rotary member rotatably mountable about a second hub the opposite the first rotary member, the second rotary member having a plurality of spaced apart and elongated second mount supports defined thereon; a second mount adjustably positioned on one of the second mount supports; and a second patient engagement member attached to the second mount. The first and second mounts are adjustably positionable on the first and second rotary members to enable adjustable positioning of the first and second patient engagement members radially relative to the first and second hubs of the rotary members and angularly relative to one another.

An adjustable rehabilitation and exercise device, including a rotary member having a plurality of elongated and spaced apart elongated open-ended slots defined thereon; a mount selectively and movably positionable on a selected one of the slots of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the selected slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The mount has a slide member configured to slidingly engage the slot and a movable plunger located on the slide member, wherein the plunger is movable to engage the slot so as to lock the position of the mount along the slot; and a patient engagement member connectable to the mount and movable with the mount.

An adjustable rehabilitation and exercise device, including a rotary member rotatable about a hub and having an elongated slot defined thereon extending radially relative to the hub, the slot including a plurality of spaced apart and opposed fingers along the length of the slots, with a plurality of gaps defined between the fingers of each side of the slot; and a mount selectively and movably positionable on a selected location on the slot of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The sliding member is configured to slidingly engage the slot, the slide member having at least one spring loaded lock configured to engage one of the gaps to lock the position of the sliding member, and a key operable by a user to disengage the lock from the gap to enable the sliding member to be moved to another location along the slot. A patient engagement member is connectable to the mount and movable with the mount.

A rehabilitation and exercise device having patient engagement members on opposite sides of a rotary member. The device includes a motor connected to the rotary member by a clutch linked to the motor. The motor is configured to desirably rotate the rotary member so that the device may serve to move the feet/legs or other extremities of a patient through a range of motion, but do not require any application of muscle force by the patient. The clutch is also operable to disconnect the motor so that the only force applied to rotary member is the muscle force of the patient. The clutch is also advantageously operable to provide continuous passive motion and enable powered movement of a desired and adjustable amount provided by the motor, yet enable desired participation by the patient in application of muscle force.

An elliptical climbing exercise apparatus includes a base frame, a swing unit including a pair of swing arms, a pedal unit including a pair of pedal shafts respectively pivotally connected to the swing arms, a damping unit including a rotating wheel with a spindle, a guiding unit including a pair of cranks respectively affixed to the two opposite ends of the spindle, a pair of rockers respectively pivotally connected to the cranks and a pair of links respectively pivotally connected to the rocker. Cooperation between the base frame, the swing unit, the pedal unit, the resistance unit and the guiding unit is used to achieve a training of the leg muscles.

An exercise apparatus may provide a novel linkage assembly suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right rocker links may be rotatably mounted on a frame rotatable about a first axis. Left and right rocker linkages may be mounted on the frame rotatable about a second axis. Left and right force receiving members may be movably connected between respective rocker links and rocker linkages in such a manner that the force receiving members move through paths of motion which are fixed, adjustable or variable.

An elliptical exercise device has a frame supporting guide links and foot support links. A cam system has a vertical control cam portion. Vertical control followers are pivotally connected to a vertical follower support. Mechanical vertical control couplings couple the foot support links to the vertical control followers. A foot receiving area of each foot support link moves in a generally elliptical path when the cam portion rotates about the cam axis.

A drive mechanism for an elliptically-driven device includes a drive arm with a foot platform pivot assembly; a crank arm; a foot platform assembly pivotally coupled to the drive arm via the foot platform pivot assembly; a foot platform angle adjustment mechanism operably coupling the foot platform assembly to the crank arm so as to impart a foot platform angle of the foot platform assembly relative to the drive arm that varies during a stroke of the foot platform assembly.

An exercise apparatus comprising: a foot support, a user interface that includes a visual display, the foot support being movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to a selection device that enables the user to select any one of the plurality of arc segments, one or more detectors adapted to detect one or more of force, energy or power exerted by the user over time on the foot support or distance or velocity of travel of the foot support or resistance assembly during the course of the user's performance of all or a portion of an exercise cycle, the visual display displaying a visually recognizable format of one or more of the force, energy, power, distance, time or velocity.
