Abstract:
1. A dumbbell caster assembly comprising a first omnidirectional wheel assembly, a second omnidirectional wheel assembly, a third omnidirectional wheel assembly, a fourth omnidirectional wheel assembly, and a grip comprising wherein the centers of the first and third wheel drums are mechanically coupled to the first end of the grip; the centers of the second and fourth wheel drums are mechanically coupled to the second end of the grip; the first and third omnidirectional wheel assemblies are separated from the second and fourth omnidirectional wheel assemblies by the grip; each wheel drum of each omnidirectional wheel assembly has an axis of rotation that is about and around the longitudinal axis of the grip; each sub-wheel of each omnidirectional wheel assembly has an axis of rotation that is orthogonal to the axis of rotation of the wheel drum of each omnidirectional wheel assembly; the first and third omnidirectional wheel assemblies are aligned such that each subwheel of the first omnidirectional wheel assembly is disposed between two subwheels of the third omnidirectional wheel assembly; and the second and fourth omnidirectional wheel assemblies are aligned such that each sub-wheel of the second omnidirectional wheel assembly is disposed between two sub-wheels of the fourth omnidirectional wheel assembly.
