An adjustable rehabilitation and exercise device, including a rotary member rotatably mounted on a hub; a mount having a ring located adjacent to the rotary member with a lock selectively engageable with the rotary member to lock the ring at an angular position relative to the rotary member, and an arm connected to the ring and extending radially relative to the rotary member and having a movable carriage associated therewith to move radially relative to the rotary member and lockable to position the carriage at a radial position relative to the rotary member; and a patient engagement member connected to the mount and movable with the carriage.

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.

A multi-axis adjustable exercise machine which is pivotable about both a pitch axis and a roll axis with respect to a base for allowing an exerciser to perform a wide range of exercises on a pitched or rolled exercise machine. The multi-axis adjustable exercise machine generally includes an exercise machine which is adjustable with respect to a base. The exercise machine may be pivoted about a roll axis to adjust the roll angle of the exercise machine or may be pivoted about a pitch axis to adjust the pitch angle of the exercise machine. One or more actuators may be connected between the base and the exercise machine to effectuate the pivoting of the exercise machine about either or both axes with respect to the base.

Various systems, processes, and techniques may be used to achieve a wheelchair-accessible exercise system. In particular implementations, a wheelchair-accessible exercise system may allow a user to perform strength and cardiovascular exercises without having to reposition his/her wheelchair. For example, a user may perform seven different exercises without moving his/her chair, or possibly even the trunk of their body. Thus, the exercise system may provide a comprehensive workout without requiring repositioning of the wheelchair, which can be quite cumbersome to those that are mobility challenged. Moreover, the exercise system may be adjustable and safe.

A resistance mechanism for an exercising device is provided. The resistance mechanism comprises a housing configured to engage the exercise device. The housing is configured to translate a resistance from a resistance generator to the exercise device. The resistance mechanism also comprises a resistance adjustment mechanism configured to adjust a level of resistance provided by the resistance mechanism. Adjustment in a first direction increases a provided resistance, and adjustment in a second direction decreases the provided resistance. The resistance generator comprises a flywheel coupled to an indexing wedge. The resistance mechanism is configured to, when the adjustment mechanism adjusts in the first direction, push against the indexing wedge in a linear direction towards and against a brake arm, causing the brake arm to engage the flywheel, thereby increasing the level of resistance provided by the resistance mechanism to the outdoor exercise device.
