This disclosure relates to the field of rehabilitation devices. More particularly, this disclosure relates to adjustable rehabilitation devices having improved connection and adjustability of patient engagement members.
Improvement is desired in the construction of adjustable rehabilitation and exercise devices. Adjustable rehabilitation and exercise devices having pedals on opposite sides and adjustably positionable relative to one another have been proposed. However, such designs require improvement due to the fact that the pedals tend to not remain securely mounted and detach, wobble and the like. In addition, it is desirable to provide for an adjustable rehabilitation or exercise device that is capable of providing both powered motion or user initiated motion without the need for separate devices.
Accordingly, in one aspect, the disclosure provides an adjustable rehabilitation and exercise device having patient engagement members on opposite sides of a rotary member. The patient engagement members are adjustably positionable radially and angularly.
The disclosure provides adjustable rehabilitation and exercise devices.
In one aspect, an adjustable rehabilitation and exercise device includes 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.
In another aspect, an adjustable rehabilitation and exercise device includes a rotary member rotatably mountable about a hub and having a plurality of spaced apart and elongated first mount supports defined on a first side thereof and a plurality of spaced apart and elongated second mount supports defined on an opposite second side thereof; a first mount adjustably positioned on one of the first mount supports; a first patient engagement member attached to the first mount; 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 positionable relative to one another on the rotary member to enable adjustable positioning of the first and second patient engagement members radially relative to the hub and angularly relative to one another.
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:

The wheel 24 is a disk configured to include a plurality of spaced apart elongated slots 24a that extend through the thickness of the wheel 24. The slots 24a include a plurality of uniformly spaced teeth or cogs 24b along both sides of the length of the slots 24a. Raised ribs 24c are located on opposite sides of a rear surface of the slots 24a for cooperating with 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 is I-shaped and includes a front plate 26a and a rear plate 26b connected by a center portion 26c. The axle 22a connects to a receiver 26e of the front plate 26a. A spring 26e is located on the rear plate 26b to urge a pin 26f toward the front plate 26a. The pin 26f extends between the spring 26e and the front plate 26a, with a tip of the pin 26f extending through an aperture 26g of the front plate 26a. The pin 26f has an enlarged head 26h that rests against the spring 26e and seats in the cogs 24b of the slot 24 to lock the position of the mount 26 relative to the slot 24.
The mount 26 is configured to stably locate the pedal 22 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 26. The pin 26f and the spring 26e cooperate with the slot 24a to provide a lock for the mount 26 to lock the position of the mount 26 relative to the slot 24a. By a user pressing on the tip of the pin 26f, which thus serves in the manner of a push button, the pressure of the spring may be overcome to disengage the head of the pin 26f from the cogs 24b and enable the mount 26 to be moved relative to the slot 24b. In this manner, the location of the mount 26 may be incrementally adjusted along the slot 24.
Accordingly, it will be appreciated that the mount 26 cooperates with the slot 24a to adjustably position the mount 26, and hence the pedal 22, relative to the wheel 24. Further, the availability of a plurality of slots 24a enables a user to select which slot 24a for installation of the mount. Thus, in combination, the mount 26 and the slots 24a enable radial and angular adjustment of the position of the pedal 22. When this manner of adjustment is used for both of the pedals 22 on opposite sides of the device 10, it will be appreciated that the pedals 22, or other 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.
