ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a jogging exerciser, and more particularly to such a jogging exerciser which enables the user to simulate the exercises of jogging, bicycle riding and skiing.
A variety of exercising machines have been developed for exercising the muscles of the legs, and have appeared on the market. These exercising machines include step exercisers, climbing exercisers, stationary bicycles, etc. However, these exercising apparatus are designed to simulate only one particular exercising action.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a jogging exerciser which enables the user to simulate the exercises of jogging, bicycle riding and skiing. According to one embodiment of the present invention, the jogging exerciser comprises a base having an upright, two handles connected to two friction wheels at opposite sides on the upright, a locating pin for fixing the handles to the upright to stop the handles from turning with the friction wheels, a crank revolvably supported on the upright, a driving wheel turned with the crank, a flywheel coupled to the driving wheel, and two parallel sliding bars slidably supported on a rack at the rear side of the base and having pivoted to both ends of the crank. Because the sliding bars are slidably supported on the rollers of the roller holders with respective front ends pivoted to the crank, the sliding bars are alternatively turned with the cranks and moved back and force when the user steps on the foot plate with the legs alternatively.
