Description

TECHNICAL FIELD AND BACKGROUND

The present invention relates, in general, to an apparatus for strengthening and rehabilitating the lower portion of the human body. More specifically, the present invention relates to a rehabilitation leg press apparatus, useable with a wheelchair, such that people that use and need wheelchairs can exercise and rehabilitate their lower bodies while remaining seated in a wheelchair with minimum risk.
The prior art discloses various apparatuses in which the wheelchair functions as a support seat for the exercise apparatus. The wheelchair is often static or stationary. In many cases, the wheelchair is fastened to pedal assemblies for a bicycle-type of exercise. Many prior exercise apparatuses make accommodations for a wheelchair in upper body exercise equipment, or include a wheelchair treadmill-type exercise apparatus, in which the wheelchair rolls on rollers when the operator pushes the large wheels of the wheelchair for upper body exercise. Some prior exercise apparatuses are provided for passive exercises for the lower body and dynamic upper body exercises, apparently since most wheelchair users have lower body handicaps or are paralyzed. None of the prior art devices includes the wheelchair as a moving part of the exercise apparatus.
Although many devices have been proposed for accommodating a patient in a wheelchair, none of these prior devices are particularly suited for use with bariatric rehabilitation patients who are regaining the ability to stand and walk, where the patient can stay in the wheelchair while exercising their legs, where the wheelchair is stabilized during exercise and prevented from tipping, especially tipping backward, where the patient can exercise in a manner that simulates and develops sit-to-stand motions and ability in patients, and where the patient can exercise so as to strengthen muscles and achieve a cardiovascular workout.
The apparatus and method of the present invention may comprise one or more features, which address one or more (or all) of the above-referenced problems and deficiencies in the prior art. Other objects, features and advantages of the present invention will be apparent from the accompanying drawings, and from the detailed description that follows below.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The present invention is an exercise apparatus for people who use wheelchairs or are wheelchair bound. The present invention is particularly suited for use with bariatric rehabilitation patients who are regaining the ability to walk. The patient can stay in the wheelchair while exercising their legs. The apparatus stabilizes the wheelchair during exercise and prevents the wheelchair from tipping, especially tipping backward. Also, the apparatus allows the therapist to monitor patient activity without manually assisting in the activity (line-of-sight supervision). The apparatus permits exercise that simulates and develops sit-to-stand motions, activity tolerance and sit-to-stand ability in patients. This type of exercise both strengthens muscles and provides a cardio-vascular workout.
In the present invention, a wheelchair exerciser assembly is provided which supports a person in a wheelchair while performing dynamic compound lower body exercises, especially leg press type or simulated sit-to-stand exercises. To achieve this function, the present invention includes structure to stabilize a wheelchair and to restrict the movement of the wheelchair to one direction or plane. Thus, the present invention includes a one-directional or single-plane slide-platform assembly to which the front wheels of a wheelchair are fixedly engaged. Although the terms “horizontal” and “vertical” may be used to describe the present apparatus, it is understood that the apparatus may be provided in any suitable configuration which performs the functions described herein. For example, the terms horizontal and vertical may describe the planes in which portions of the apparatus are disposed, but are not intended to limit the configuration of the apparatus to strictly horizontal and vertical configurations. The entire device may be provided at an angle so that the direction of back-and-forth motion is along an inclined plane.
Further, the present invention includes a pushing-platform that the patient pushes with his feet and resistive apparatus that provide resistive force against which the patient must push. The wheelchair exerciser is designed to accommodate a large variety of wheelchair sizes. The present invention is designed to be especially used in a physical therapy or physical rehabilitation setting.
FIG. 1 is a side view of an embodiment of the present leg press apparatus 10 with a wheelchair 12 positioned in an operative position in the apparatus 10. The apparatus 10 has a base structure (or support chassis or support structure) 16. The base structure 16 may be made of one-piece construction or multiple components as shown. The base structure 16 may be made of any suitable material, such as wood, plastic or metal or a combination of wood, plastic and/or metal. If the base structure 16 is provided with multiple components as shown, the components may be connected using any suitable means of connection, such as screws.
The base structure may comprise a lower plate 16 a, a pair of lower beams 16 b on the lower plate 16 a, a pair of middle plates 16 c on the lower beams 16 b, a pair of upper beams 16 d, and a pair of upper plates or restrictor plates 16 e on the pair of upper beams 16 d. As detailed in FIG. 4, the lower plate 16 a may be connected with a cross beam 17, which is provided between the pair of lower beams 16 b.
The base structure 16 may be provided with a vertical support member 18 and may be stabilized with the aforementioned cross beam 17 and a corner support member 19. The support members 18 and 19 may be constructed in a manner similar to that of the base structure 16 described above. For example, the vertical support member 18 may be formed of plywood and attached to base structure 16 with screws and with a corner support member 19 formed of metal, plastic, PVC or the like. The corner support member 19 may also be attached with any suitable means for connection, such as screws. In the illustrated embodiment, the corner support member 19 is triangular in shape and comprises a horizontal piece, a vertical piece and an angled cross piece between the horizontal and vertical pieces, where the horizontal piece is attached to the base structure 16 and the vertical piece is attached to the vertical support member 18, and where the angled cross piece is integrated into a one-piece construction with the horizontal and vertical pieces.
Referring, for example, to FIG. 2, a press board 14 may be attached between the vertical support member 18 and the base structure 16. Specifically, the press board 14 may be provided at an angle A with respect to the vertical and attached at a top of the vertical support member 18 and to a top side of the lower plate 16 a. In operation, a patient places his or her feet against the press board 14. It has been found than the angle A should be less than about 45 degrees with respect to the vertical, preferably between about 15 degrees and about 30 degrees, and even more preferably between about 20 degrees and about 25 degrees. It has been found that by positioning of the press board 14 at the angle A within the ranges specified above, an optimal position is provided for the patient during exercise. The press board 14 may be provided such than angle A may be adjustable for individual preference.
The press board 14 may further comprise a foot support 20. The foot support 20 may also be adjustable in any direction on the press board 14 and may be adapted to receive the feet of the patient during exercise or individualized to meet the needs of a particular patient.
A means for resistance 26 may be attached at any suitable position on the apparatus 10. For example, in an example of a relatively simple type of construction, the means for resistance 26 may be attached to the press board 14 using stays, eyelets or loops 15. The stays, eyelets or loops 15 could be screwed into the press board 14 or attached using any suitable means. The stays, eyelets or loops 15 may be made of suitable material such as metal, wood, plastic or the like.
The means for resistance 26 may be made of any suitable material. For example, the means for resistance 26 may be one or more means of dynamic resistance, such as elastic bands or bungee cords. In the illustrated embodiment, three pair of bungee cords are used, one pair on each side. Multiple resistances could be achieved by providing elastic bands or bungee cords with different levels of elastic resistance and/or by providing multiple bands or cords which together achieve the desired resistance. In any event, the means for resistance 26 is provided between the wheelchair 10 and the press board 14. In operation, the wheelchair 10 is provided in a carriage 32 (to be described in greater detail below), and as the patient presses on the press board 14, the means for resistance 26 provides resistance to the legs of the patient as the carriage 32 moves with the wheelchair 10.
FIG. 2 is a side view of an embodiment of the present leg press apparatus 10 without the wheelchair 12. In addition to the features described above, FIG. 2 also shows wheel receptacles 34 provided in the carriage 32. Although an opening is shown in the illustrated embodiment, any suitable means for securing the wheelchair 10 may be provided. For example, the wheel receptacles 34 may be an opening in the carriage 32 (as shown), or the wheel receptacles 34 could be a wheel cup (not shown) provided in a shape specifically adapted to receive front wheels 13 of the wheelchair 10. The wheel cup could be made of any suitable material such as metal, plastic or wood.
Also, the carriage 32 comprises a pair of upper wheels 36 attached to the carriage 32 with mounting brackets 35. It is noted that one of the pair of upper wheels 36 is shown in FIG. 2. Both of the pair of upper wheels 36 are shown, for example, in FIGS. 3, 4 and 6. Although upper wheels 36 are shown, any suitable means of providing for the horizontal movement of the carriage 32 may be employed.
Also, FIG. 2 shows a pair of tracks 30 adapted to receive and secure a pair of lower wheels 38 (as detailed in FIGS. 3 and 4). Although a pair of tracks 30 are shown, any suitable means of receiving and securing the lower wheels 38 may be used. The tracks 30 may be made of any suitable material such as metal, wood or plastic.
FIG. 3 is a front view of an embodiment of the present leg press apparatus 10 with a wheelchair 12 positioned in an operative position in the apparatus 10. In addition to the features shown in FIGS. 1 and 2, FIG. 3 also shows that the carriage 32 comprises a pair of lower wheels 38 attached to the carriage 32 with mounting brackets 37.
FIG. 4 is a front view of an embodiment of the present leg press apparatus 10 without the wheelchair 10 including all the features shown in FIGS. 1-3.
FIG. 5 is a partial top view of a wheelchair 12 positioned in a carriage 32 of the leg press apparatus 10 in an embodiment of the present leg press apparatus 10. As noted above, the means for resistance 26 may be attached at any suitable position on the apparatus 10 and elastic bands or bungee cords may be used as the means for resistance 26. As detailed in FIG. 5, for example, a first end of a first band or cord may be attached to a first loop, the first band or cord may be wrapped around a first side of the frame of the wheelchair 10, and a second end of the first band or cord may be attached to the same first loop. Then, a first end of a second band or cord may be attached to a second loop, the second band or cord may be wrapped around a second side of the frame of the wheelchair 10, and a second end of the second band or cord may be attached to the same second loop. Also, a means for static resistance, such as a fastening strap, stay tether, steel rod or bar 40 made of woven nylon, rope, metal or any other suitable material, can be attached between the wheelchair 10 and the carriage 32. Although any suitable means for static resistance may be used, as shown in FIG. 5, a first end of the strap or tether 40 can be attached to a first stay, eyelet or loop 33 on one side of the carriage 32, the strap or tether 40 can be looped through the frame of the wheelchair 10 and a second end of the strap or tether 40 can be attached to a second stay, eyelet or loop 33 on another side of the carriage 32. Optionally, a rigid retaining bar may be used instead of the strap or tether 40.
FIG. 6 is a partial side view of the carriage 32 of the leg press apparatus 10 in an embodiment of the present leg press apparatus 10. FIG. 6 details the pair of upper wheels 36 adapted to roll against a bottom side of the pair of upper plates or restrictor plates 16 e. Since the pair of upper wheels 36 are adapted to roll against the bottom side of the pair of upper plates or restrictor plates 16 e, the carriage 32 is restricted from vertical movement within the apparatus 10. As noted above, the entire apparatus 10 may be disposed at an angle, and it is understood that the restrictor plates 16 e would still function to prevent improper or undesired disengagement of the wheelchair 12 from the apparatus 10. Since the wheelchair 10 is attached to the carriage 32 with a means for static resistance, such as fastening strap, stay tether, steel rod or bar 40 (see, for example, FIG. 5), the wheelchair 10, in operation, is restricted by the pair of upper plates or restrictor plates 16 e and is thus prevented from tipping over or rising off the surface formed by lower plate 16 a during operation. This provides stability to the patient and permits the patient to engage in a full range of motion and increased force during exercise thus improving the exercise for the patient.
FIG. 7 is a side view of the entire apparatus 10 may be provided at an angle so that the lower plate 16 a is disposed at an incline and so that the wheelchair 12 rolls back and forth in a direction that is not horizontal. For example, the apparatus 10 may be disposed at any angle between 0 and 45 degrees. As the angle increases, the patient would need to increase the force required to complete a repetition. As such, the leg press apparatus may be adapted to incorporate the force of gravity into the exercise. Shown is a control button 50 to drop the apparatus 10 to a level position.
In one embodiment of the present invention, an apparatus for rehabilitation of a patient, such as a bariatric patient, sitting in a wheelchair 12, is provided.
