Abstract
A treadmill device includes two treadmills disposed above a base and each having a tread supported around a platform and each has one end rotatably supported on the base with a shaft which may be driven by a motor. An arm has a middle portion pivotally supported on the base and has two ends located below and coupled to the treadmills, for elevating one of the treadmills when the other treadmill is lowered, such that the two treadmills may be operated as a stepping exerciser. A latch may be used to lock the treadmills together.
Claims34
A treadmill apparatus comprising:
- a base including a first end, and including a second end having a shaft provided thereon,
- a pair of treadmills disposed above said base, and each including a platform having a roller provided on a first end thereof and attached to said shaft, and each including a tread supported around said platform,
- means for driving said shaft to actuate said treads,
- an arm including a middle portion pivotally supported on said base with a pivot axle, and including two ends located below said treadmills respectively, and
- means for coupling said ends of said arm to said treadmills to elevate a first of said treadmills when a second of said treadmills is lowered, and to elevate said second treadmill when said first treadmill is lowered.
An exercise apparatus comprising:
- a base;
- a first treadmill assembly operatively coupled with the base and supported in pivotal relation with the base;
- a second treadmill assembly operatively coupled with the base and supported in pivotal relation with the base;
- a reciprocating coupling assembly interconnected between the first treadmill assembly and the second treadmill assembly, the reciprocating coupling assembly constraining the first treadmill assembly and the second treadmill assembly to move in opposite directions when reciprocating;
- a shaft operatively supported by the base;
- the first treadmill assembly pivotally supported at the shaft;
- and
- the second treadmill assembly pivotally supported at the shaft.
An exercise apparatus comprising:
- a base;
- a first treadmill assembly in pivotal relation with the base;
- a second treadmill assembly in pivotal relation with the base;
- a coupling device pivotally coupled with the base, the coupling device further coupled with the first treadmill assembly and the second treadmill assembly;
- a shaft operatively supported by the base;
- the first treadmill assembly pivotally supported at the shaft;
- and
- the second treadmill assembly pivotally supported at the shaft, whereby the coupling device is adapted to elevate the first treadmill assembly when the second treadmill assembly is depressed, and to elevate the second treadmill assembly when the first treadmill assembly is depressed.
