Abstract

A caster assembly having a top cap configured to engage with a structure, a caster leg configured to pivotally engage with the top cap, such that the caster leg selectively pivots about a pivot axis, and a pair of sinusoidal wheels configured to be rotationally engaged with the caster leg, the sinusoidal wheels being configured to rotate about a wheel rotational axis and swivel with the caster leg as a required when the structure is moved. An angled member of the caster leg may be configured to engage with the sinusoidal wheels such that the wheel rotational axis is not intersected by the pivot axis. An offset angle formed between the angled member and a vertical member of the caster leg, when used in conjunction with the disclosed sinusoidal wheels, is configured to ease structure movement by minimizing resistances exerted on the sinusoidal wheels during rolling and caster leg pivoting.
