ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a motorized exercise bicycle for the physically impaired or disabled.
DESCRIPTION OF THE PRIOR ART
The infirm, the elderly, those who have recently suffered debilitating injuries or diseases and similar physically disabled people often attempt a minimal amount of exercise during rehabilitation or to maintain minimum muscle strength or conditioning. However, conventional exercises such as walking, biking, jogging or swimming are typically too strenuous for a person with such physical disabilities, especially for those who have suffered a stroke or a similar serious medical emergency.
The present invention provides a motorized exercise bicycle in which a pedal assembly can be selectively rotated with a motor to exercise a user's legs resting thereon. Furthermore, the motor reciprocates a pair of handle bars to lightly work the arms and upper body.
Various exercise devices exist in the prior art. For example, U.S. Pat. No. 5,501,648 issued to Grigoriev relates to an exercise device including a front wheel and a reciprocating handle bar assembly attached to a frame. A clutch and a mechanical advantage device are utilized to drive the front wheel of the bicycle in response to the reciprocative displacement of the handle bar assembly.
U.S. Pat. No. 5,346,445 issued to Chang relates to an arm lever for an exercise bicycle including a pivot portion pivotably mounted on a front end of a bicycle frame and a bottom end connected to the end of a crank arm.
U.S. Pat. No. 5,149,312 issued to Croft et al relates to a quick release apparatus for a link member for an exercise bicycle.
U.S. Pat. No. 5,035,417 issued to Ross relates to an exercise bicycle including reciprocating arms which are interlinked with a flywheel such that movement of the arms causes rotation of the flywheel.
U.S. Pat. No. 4,981,294 issued to Dalebout et al relates to an exercise bicycle including a wheel having a plurality of fan blades to provide air resistance when the wheel is rotated. In addition, the hub of the wheel is circumferentially encompassed with a strap that may be tightened to increase the rotational resistance applied to the wheel.
Although various exercise bicycles and mechanisms therefor exist in the prior art, none include an electric motor for automatically driving a pedal assembly and reciprocating handle bars.
SUMMARY OF THE INVENTION
The present invention relates to a motorized exercise bicycle. The device comprises a frame having a fan blade type wheel mounted thereon. Interlinked with the wheel is a pedal assembly whereby rotation of the pedal results in rotation of the wheel. The bicycle also includes reciprocating handle bars which are likewise operably interlinked with the motor and are simultaneously reciprocated with rotation of the wheel. It is therefore an object of the present invention to provide an exercise bicycle having an electric motor assembly for automatically rotating a pedal assembly.
It is another object of the present invention to provide an exercise bicycle having automatically reciprocating handle bars.
