In another aspect, an adjustable rehabilitation and exercise device includes a rotary member rotatable on a hub and having a plurality of elongated and spaced apart elongated mount receivers defined thereon, the mount receivers each comprising an elongated track located on the rotary member and a row of pegs located on the rotary member along the length of the track; 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, the mount comprising a slide member configured to slidingly engage the track 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 track; and a patient engagement member connectable to the mount and movable with the mount.

BRIEF DESCRIPTION OF THE DRAWINGS

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-2C 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 central 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. For example, 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-2C, there is shown a wheel system 20 configured to have a patient engagement member, such as a pedal adjustably mounted on a wheel 24 by an adjustable mount 26. It will be appreciated that the patient engagement member may be configured to engage a hand or foot or other member of a patient as may be desired for rehabilitation. The pedal may be a conventional pedal and includes a support rotatably mounted on an axle having exposed threads for being received by a corresponding threaded aperture of the mount 26. It will be appreciated that a pair of the wheels 24 may be utilized or, alternatively, a single one of the wheels 24 with a mount and pedal on each side.

The wheel 24 is a disk configured to include a plurality of spaced apart elongated elevated tracks 24a formed on the wheel 24 to receive the mount 26. The tracks 24a include a U-shaped interior channel 24b, and a plurality of uniformly spaced raised pegs 24c along both sides of the length of the bridges 24a. The tracks 24a may be open at each end to facilitate installation and removal of the mount 26.

The wheel 24 also includes a hub or central mounting aperture 24d for rotatably mounting of the wheel 24, such as to the device 10. Material of the wheel 24 may be removed to provide openings 24e to provide aesthetics and for reducing the weight and the cost of the wheel 24.

The mount 26 includes a slide member 26a configured to slidingly engage the track 24a. The slide member 26a preferably wraps around portions of the track 24a and includes an outward facing receiver 26b to which a patient engagement member, such as a pedal, may be connected. The mount 26 also includes a tower 26c having a pair of spaced apart hollow cylindrical legs 26d. A spring-loaded plunger 26e having a handle 26f is mounted to a central portion of the tower 26c.

The mount 26 is shown locked or secured in FIG. 2B, with the legs 26d seated onto the pegs 24c at a radial location on the wheel 24 relative to the central mounting aperture 24d which serves to locate the hub to define a rotational axis. As shown in FIG. 2B, the spring-loaded plunger 26e applies force to the channel 24b to seat the legs 26d on the pegs 24c and otherwise securely locate the mount 26 onto the track 24a.

FIG. 2C shows the plunger 26e released, as by pulling upward on the handle 26f The tower 26c may then be lifted to move the slide member 26a and position it so the legs 26d are seated on a pair of the pegs 24c corresponding to a different radial location. Once the mount 26 is relocated with the legs 26d seated onto a different pair of the pegs 24c at a desired position, the handle 26f is released to reapply the plunger 26e and securely locate the mount 26 at the new radial location on the wheel 24.

The mount 26 is configured to stably locate a pedal or other 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 mount 26 cooperates with the track 24a to adjustably position the mount 26, and hence the pedal, relative to the hub on which the wheel 24 rotates. Further, the availability of a plurality of tracks 24a enables a user to select which track 24a for installation of the mount 26. Thus, in combination, the mount 26 and the tracks 24a enable radial and angular adjustment of the position of the pedal or other patient engagement member. When this manner of adjustment is used for both of the pedals on opposite sides of the device 10, it will be appreciated that the pedals, or other patient engagement members, may each be adjustably positioned radially relative to the hub on which the wheels rotate, and angularly relative to one another.

The foregoing description of preferred embodiments for this disclosure has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the disclosure and its practical application, and to thereby enable one of ordinary skill in the art to utilize the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the disclosure.
