Exercise wheel

摘要

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.

1. An exercise wheel comprising:
an axle including two ends spaced from each other along a longitudinal axis of the axle and an intermediate section between the two ends; two wheel assemblies respectively and rotatably mounted to the two ends of the axle, with each of the two wheel assemblies rotatable about the longitudinal axis, with each of the two wheel assemblies including an outer periphery surrounding the longitudinal axis, with a plurality of first grooves defined in the outer periphery of each of the two wheel assemblies and spaced from each other in a circumferential direction about the longitudinal axis, with the intermediate section of the axle located between the two wheel assemblies, with a plurality of second grooves defined in the outer periphery of each of the two wheel assemblies, and with each of the plurality of second grooves located between two adjacent first grooves; a plurality of first rollers respectively and rotatably mounted in the plurality of first grooves of each of the two wheel assemblies, with each of the plurality of first rollers rotatable relative to a corresponding one of the two wheel assemblies about a first rotating axis; and a plurality of second rollers respectively and rotatably mounted in the plurality of second grooves of each of the two wheel assemblies, with each of the plurality of second rollers rotatable relative to a corresponding one of the two wheel assemblies about a second rotating axis, and with the second rotating axis of each of the plurality of second rollers being parallel to and spaced from the longitudinal axis and being at a non-parallel angle to the first rotating axis of one of the plurality of first rollers adjacent thereto.
