Patent attributes
An exercise wheel includes two wheel assemblies rotatably mounted to two ends of an axle. Each wheel assembly is rotatable about a longitudinal axis. A plurality of first grooves and a plurality of second grooves are defined in an outer periphery of each wheel assembly. Each second groove is located between two adjacent first grooves. A first roller is rotatably mounted in each first groove of each wheel assembly. Each first roller is rotatable relative to a corresponding wheel assembly about a first rotating axis. A second roller is rotatably mounted in each second groove of each wheel assembly. Each second roller is rotatable relative to a corresponding wheel assembly about a second rotating axis. The second rotating axis of each second roller is parallel to and spaced from the longitudinal axis and is at a non-parallel angle to the first rotating axis of an adjacent first roller.
