Further advantages of the disclosure are apparent by reference to the detailed description when considered in conjunction with the figures, which are not to scale so as to more clearly show the details, wherein like reference numbers indicate like elements throughout the several views, and wherein:

FIGS. 1A and 1B are perspective views of an adjustable rehabilitation and exercise device according to the disclosure configured to have adjustably positionable patient engagement members.

FIGS. 2A-2G show a wheel system for adjustably positioning a patient engagement member.

DETAILED DESCRIPTION

With initial reference to FIGS. 1A-1B, there is shown an adjustable rehabilitation and exercise device 10 having patient engagement members, such as pedals 12 on opposite sides that are adjustably positionable relative to one another, but securely mounted according to the disclosure to provide a more secure mounting that avoids disconnection, wobbling and the like often experienced with prior devices.

The device 10 includes a rotary device such as a wheel 14 or flywheel or the like rotatably mounted such as by a hub to a frame 16 or other support. The pedal 12 is configured for interacting with a patient to be rehabilitated and may be configured for use with lower body extremities such as the feet, legs, or upper body extremities such as the hands, arms and the like.

The pedal 12 may be a conventional bicycle pedal of the type having a foot support rotatably mounted onto an axle with bearings. The axle has exposed end threads for engaging a mount on the wheel 14 to locate the pedal on the wheel 14.

The wheel 14 may be configured to have both pedals 12 on opposite sides of a single wheel. However, a preferred construction, as seen in FIGS. 1A and 1B shows a pair of the wheels 14 spaced apart from one another but interconnected to a flywheel or the like.

The rehabilitation and exercise device 10 of FIGS. 1A-1B may take the form as depicted of a traditional exercise/rehabilitation device which is more or less non-portable and remains in a fixed location, such as a rehabilitation clinic or medical practice.

Alternatively, the device 10 may be configured to be smaller and more portable unit so that it is able to be easily transported to different locations at which rehabilitation or treatment is to be provided, such as a plurality of patient's homes, alternative care facilities or the like.

With reference to FIGS. 2A-2G, there is shown a wheel system 20 having a patient engagement member, such as a pedal 22 adjustably mounted on a wheel 24 by an adjustable mount 26. The wheel system 20 advantageously enables patient engagement members, such as pedals, to be radially and angularly adjustable relative to one another on opposite sides of an exercise device, such as the device 10.

The pedal 22 may be a conventional pedal and includes a support rotatably mounted on an axle 22a. The axle 22a has exposed threads for being received by a corresponding threaded aperture of the mount 26

The wheel 24 (FIGS. 2E-2G) is a disk configured to include a plurality of spaced apart apertures 24a located on the circumference of the wheel 24. The wheel 24 may also include a hub or central mounting aperture 24b for mounting of the wheel 24 to the device 10, and apertures 24c for connection of the wheel 24. The wheel also includes a nose 24d.

The mount 26 includes an angular adjustment system 27 and a radial adjustment system 28. The angular adjustment system 27 includes a ring 27a, a lock pin 27b, an arm 27c, a hub 27d, a hub fastener 27e, and a hub retainer 27f. The wheel 24 connects to the hub 27d by use of fasteners 27g which pass through the apertures 24c of the wheel and into corresponding apertures on the hub 27d.

The hub 27d, hub fastener 27e and the hub retainer 27f pivotally connect the arm 27c to the wheel 24. The ring 27a seats over the nose 24d of the wheel 24 and attaches to the arm 27c as by fasteners 27h. The lock pin 27b extends through an aperture 27i of the ring 27a to align with one of the apertures 24a of the wheel 24 to lock the angular relation of the arm 27c to the wheel 24.

To adjust the angular relationship of the arm 27c, and hence the pedal 22, to the wheel 24, the pin 27b located on the ring 27a is withdrawn from the aperture 27i and the angle adjusted by rotating the arm 27b. Once the angle is adjusted, the pin 27b is re-inserted through the aperture 27i to enter a different one of the apertures 24a of the wheel 24a that corresponds to the adjusted angle. The number of the apertures 24a may be selected to provide a desired increment of adjustment.

The radial adjustment system 28 includes a rail 28a, walls 28b having adjustment apertures 28c, carriage 28d, receiver 28e, and locking pin 28f. The rail 28a mounts to the arm 27b as by fasteners. The walls 28b are spaced apart above and below the rail 28a. The carriage 28d is slidably disposed on the rail 28a, with the receiver 28e affixed thereto to receive the axel 22a of the pedal 22, or other patient engagement member. The locking pin 28f extends through the apertures 28c of the walls 28b to fix the location of the carriage 28d and the receiver. The receiver 28e includes an aperture 28g for passage of the locking pin 28f.

To adjust the radial relationship of the pedal 22, the carriage 28d is moved along the rail 28a. The locking pin 28f is extended through the aperture 28g of the receiver 28e and the apertures 28c of the walls 28b to lock the radial location of the carriage 28d, and hence the pedal 22.

The mount 26 is configured to stably locate a patient engagement member and eliminate wobble and the like associated with conventional devices. In addition, the mount 26 is also configured to advantageously enable substantially incremental adjustment of the position of the mount.

The angular adjustment system 27 adjusts the angular position of the pedal 22, or other patient engagement member, relative to the wheel 24. The radial adjustment system 28 adjusts the radial position of the patient engagement member, relative to the wheel 24.

In combination, the angular adjustment system 27 and the radial adjustment system 28 enable radial and angular adjustment of the position of the pedal 22. When this manner of adjustment is used for both of the pedals on opposite sides of the device 10, the patient engagement members may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.
