Exercise device with treadles
View Patent ↗An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.
1. An exercise apparatus comprising:
a right treadle assembly having a deck and an endless tread belt that runs over the deck to provide a right moving tread surface, the right treadle assembly being pivotable about a pivot axis;
a left treadle assembly having a deck and an endless tread belt that runs over the deck to provide a left moving tread surface, the left treadle assembly being pivotable about the pivot axis;
an interconnection assembly positioned primarily below and operably connecting the right and left treadle assemblies so that pivotal movement of either of the right and left treadle assemblies in a first direction causes pivotal movement of the other of the right and left treadle assemblies in a second direction that is opposite the first direction; and
a resistance element positioned primarily below the right and left treadle assemblies and coupled to the interconnection assembly to resist pivotal motion of the first and second treadle assemblies, and the resistance element including a torsion spring element coupled to the interconnection assembly to provide torsion resistance to movement of the interconnection assembly.
2. The exercise apparatus of claim 1 wherein the right and left treadle assemblies are pivotable about a pivot axle that is aligned with the pivot axis.
3. An exercise apparatus comprising: a right treadle assembly having a deck and an endless tread belt that runs over the deck to provide a right moving tread surface, the right treadle assembly being pivotable about a pivot axis; a left treadle assembly having a deck and an endless tread belt that runs over the deck to provide a left moving tread surface, the left treadle assembly being pivotable about the pivot axis; an interconnection assembly that includes a rocker having right and left arms that are coupled to the respective right and left treadle assemblies so that pivotal movement of either of first and second treadle assemblies in a first direction causes pivotal movement of the other of the first and second treadle assemblies in a second direction that is opposite the first direction; and a torsion spring resistance element positioned primarily below the first and second treadle assemblies and coupled to the interconnection assembly to resist pivotal motion of the first and second treadle assemblies.
4. An exercise apparatus comprising: a right treadle assembly having a deck and an endless tread belt that runs over the deck to provide a right moving tread surface, the right treadle assembly being pivotable about a pivot axis; a left treadle assembly having a deck and an endless tread belt that runs over the deck to provide a left moving tread surface, the left treadle assembly being pivotable about the pivot axis; an interconnection assembly that includes a rocker having right and left arms that are coupled to the respective right and left treadle assemblies so that pivotal movement of either of first and second treadle assemblies in a first direction causes pivotal movement of the other of the first and second treadle assemblies in a second direction that is opposite the first direction; and leaf spring resistance elements positioned primarily below the first and second treadle assemblies and coupled to the interconnection assembly to resist pivotal motion of the first and second treadle assemblies.
5. The exercise apparatus of claim 1 wherein the right and left spring elements include leaf spring elements to provide resistance to movement of respective right and left arms of the rocker.
6. The exercise apparatus of claim 1 wherein the right and left spring elements include coil spring elements to provide resistance to movement of respective right and left arms of the rocker.
