Abstract
A low profile wheel assembly suitable for use in dollies, decks or any other platform designed for moving freight or other heavy items. It includes a wheel, a carriage on which the wheel bracket is mounted for rotation about a first axis. The wheel carriage unit fits inside an outer housing unit of this wheel assembly and by means of low friction between the wheel carriage unit and the outer housing unit enabling the wheels carriage unit to rotate concentrically while inside the outer housing unit at a different axis than the first. In this manner and at the same time that the wheel is rolling on a surface, it can change directions of where it is rolling to.
Claims12
A swivel wheel assembly, comprising:
- an outer housing;
- a carriage wheel assembly rotatably received in and rotating relative to the outer housing about an axis, the carriage wheel assembly including a carriage and a wheel rotatably mounted within and rotating relative to the carriage about an axis different from the axis that the carriage wheel assembly rotates about, the wheel including a longitudinal length and a diameter, and the longitudinal length of the wheel is greater than the diameter of the wheel, maximizing weight distribution on the wheel and minimizing marking or damaging a contacting surface,
- wherein the outer housing includes an outer lip and the carriage includes an outer lip that overlaps the outer lip of the outer housing to block debris from entering between the carriage wheel assembly and the outer housing and impeding rotation and allowing smooth sliding on surfaces that the wheel will be difficult to roll on.
A swivel wheel assembly, comprising:
- an outer housing;
- a carriage wheel assembly rotatably received in and rotating relative to the outer housing about an axis, the carriage wheel assembly including a carriage and a wheel rotatably mounted within and rotating relative to the carriage about an axis different from the axis that the carriage wheel assembly rotates about, the wheel including a longitudinal length and a diameter, and the longitudinal length of the wheel is greater than the diameter of the wheel, maximizing weight distribution on the wheel and minimizing marking or damaging a contacting surface,
- wherein the carriage wheel assembly includes a hole and the outer housing includes one or more projections that is rotatably received in the hole to allow the carriage wheel assembly to be rotatably received in and rotating relative to the outer housing,
- the one or more projections include a plurality of flexible tabs that are both lockingly engaged within and rotatably received within the hole to allow the carriage wheel assembly to be rotatably received in and rotating relative to the outer housing.
A swivel wheel assembly, comprising:
- an outer housing;
- a carriage wheel assembly rotatably received in and rotating relative to the outer housing about an axis, the carriage wheel assembly including a carriage and a wheel rotatably mounted within and rotating relative to the carriage about an axis different from the axis that the carriage wheel assembly rotates about, the wheel including a longitudinal length and a diameter, and the longitudinal length of the wheel is greater than the diameter of the wheel, maximizing weight distribution on the wheel and minimizing marking or damaging a contacting surface,
- wherein the carriage includes an outer tapered lip to block debris from entering between the carriage wheel assembly and the outer housing and impeding rotation and allowing smooth sliding on surfaces that the wheel will be difficult to roll on.
