Patent attributes
A self-supporting rigid cylindrical treadwheel includes a plurality of identically-shaped platforms each having a curved surface. A first end of one platform is configured to be connectable to a second end of an adjacent platform in a repeatable manner where the plurality of platforms are configured to form a singular and continuous cylindrical structure. The treadwheel includes a plurality of identically-shaped elongated curved connectors. A connector extension of one connector is configured to be connectable to a connector recess of an adjacent connector in a repeatable manner where the plurality of connectors are configured to form a first and second singular and continuous ring. The first ring is configured to be attached to a right side of the cylindrical structure and the second ring is configured to be attached to a left side of the cylindrical structure.
