Collapsible wheel assembly
A wheel assembly and a method of using the wheel assembly are provided. The wheel assembly is attachable to various objects and capable of quickly and easily collapsing or folding to become more compact for more efficient and cost-effective transportation or shipping. It is then capable of being quickly and easily expanded.
1. A method of using a collapsible wheel assembly, the method comprising:
providing a collapsible wheel assembly including:
a base,
a plurality of wheels, and
a plurality of axles having opposite first and second ends, the second end of each of the axles is pivotally connected to the base, each of the axles having at least one of the wheels located thereon adjacent the respective first ends of the axles such that the wheels are respectively slideable along an associated one of the axles;
rotating the axles toward each other; and
sliding the wheels along the length of the axles until the wheels mechanically interfere with each other.
2. The method of claim 1 , wherein each of the axles are pivotally connected to a bracket on the base and moveable within a defined plane.
3. The method of claim 1 , wherein the base of the collapsible wheel assembly further comprises:
first and second ends; and
flanges located at the first and second ends.
4. The method of claim 3 , further comprising at least one slot sized to receive one of the axles defined in each of the flanges; and
the method further comprising the step of removing each of the axles from the respective slot prior to rotating the axles toward each other.
5. The method of claim 4 , wherein each of the slots comprise first and second sides, each side having a protrusion configured to interfere with an axle when the axle is seated in the slot.
6. The method of claim 1 , wherein the base is comprised of first and second faces, the axles being pivotally connected to the first face of the base; and
the method further comprises the step of connecting an object to the first face of the base.
7. A method of using a collapsible wheel assembly, the method comprising:
providing a collapsible wheel assembly having a collapsed state and an expanded state, the wheel assembly including:
a base having first and second faces,
a plurality of wheels, and
a plurality of axles having opposite first and second ends, the second end of each of the axles is pivotally connected to the second face of the base, each of the axles having at least one of the wheels located thereon adjacent the respective first ends of the axles such that the wheels are respectively slideable along an associated one of the axles;
the collapsible wheel assembly is collapsed by rotating the axles toward each other and sliding the wheels along the length of the axles until the wheels mechanically interfere with each other; and
the collapsible wheel assembly is expanded by rotating the axles away from each other and sliding the wheels along the length of the axles toward the first end of each axle.
8. The method of claim 7 , wherein each of the axles are pivotally connected to a bracket on the base and moveable within a defined plane.
9. The method of claim 7 , wherein the base of the collapsible wheel assembly further comprises:
first and second ends; and
flanges located at the first and second ends.
10. The method of claim 9 , further comprising at least one slot sized to receive one of the axles defined in each of the flanges; and
the method further comprising the step of removing each of the axles from the respective slot prior to rotating the axles toward each other.
11. The method of claim 10 , wherein each of the slots comprise first and second sides, each side having a protrusion configured to interfere with an axle when the axle is seated in the slot.
12. The method of claim 7 , wherein the method further comprises the step of connecting an object to the first face of the base.
