Abstract

A folding dolly system, a base unit of a folding dolly system, and methods of forming and using a folding dolly system are presented. A folding dolly system comprises a plurality of interconnectable base units connected to form a substantially planar holding surface, each base unit comprising a first edge with a number of knuckles configured to form a joint, a second edge with a number of knuckles configured to form a joint, and a surface forming a portion of the holding surface.

First claim

What is claimed is:

1. A folding dolly system comprising:
a plurality of interconnectable base units connected to form a substantially planar holding surface, each base unit comprising a first edge with a number of knuckles configured to form a joint, a second edge with a second number of knuckles configured to form a joint, and a surface forming a portion of the holding surface, wherein the number of knuckles and the second number of knuckles of each base unit are connected to a bottom of the base unit such that the number of knuckles and the second number of knuckles are each positioned beneath the surface of the base unit and beneath the bottom of the base unit; and
a plurality of wheels connected to the plurality of interconnectable base units.

2. The folding dolly system of claim 1 , wherein the plurality of interconnectable base units is connected by a plurality of joints, and wherein each joint of the plurality of joints is formed by a number of connectors.

3. The folding dolly system of claim 2 , wherein the number of connectors comprises at least one of a number of shoulder bolts or a pin.

4. The folding dolly system of claim 2 , wherein the folding dolly system is configured to fold into a plurality of rows around an axis, the plurality of rows connected by the plurality of joints.

5. The folding dolly system of claim 4 , wherein the plurality of rows is configured to move relative to each other about the plurality of joints to move the folding dolly system between a stored position and a deployed position, wherein the folding dolly system forms the substantially planar holding surface in the deployed position, and wherein the plurality of rows comprises a plurality of surfaces wrapping around the axis in the stored position, wherein the plurality of surfaces is configured to join to form the substantially planar holding surface in the deployed position.

6. The folding dolly system of claim 1 , wherein each base unit is connected to at least one wheel of the plurality of wheels.

7. The folding dolly system of claim 6 , wherein each base unit has a same design including a location of a connection to a wheel of the plurality of wheels.

8. The folding dolly system of claim 1 , wherein the first edge and second edge of each base unit is configured to react against a respective first edge or second edge of an adjacent base unit to form the holding surface to be substantially planar.

9. The folding dolly system of claim 1 , wherein each base unit of the plurality of interconnectable base units comprises a third edge and a fourth edge, wherein each third edge and each fourth edge of a respective base unit are each substantially planar and substantially perpendicular to the surface of the respective base unit.

10. The folding dolly system of claim 1 further comprising:
a handle connected to at least one base unit of the plurality of interconnectable base units.

11. A method comprising:
sending a connector through a number of knuckles of a first edge of a base unit to form a joint of a folding dolly system comprising a plurality of interconnectable base units including the base unit, wherein the number of knuckles is connected to a bottom of the base unit such that the number of knuckles is positioned beneath a surface of the base unit and beneath the bottom of the base unit, wherein sending the connector through the number of knuckles joins the surface of the base unit to surfaces of remaining base units of the plurality of interconnectable base units to form the folding dolly system, wherein the folding dolly system comprises: a holding surface formed by a respective surface of each of the plurality of interconnectable base units, a plurality of joints connecting the plurality of interconnectable base units into a plurality of rows rotatably connected by the plurality of joints, and a plurality of wheels connected to the plurality of interconnectable base units, wherein the folding dolly system is configured to fold into the plurality of rows around an axis.

12. The method of claim 11 further comprising:
rolling the plurality of interconnectable base units about the axis to separate the holding surface into the plurality of rows.

13. The method of claim 11 further comprising:
unrolling the plurality of interconnectable base units to arrange the holding surface to be substantially planar.

14. The method of claim 13 further comprising:
placing the plurality of wheels of the folding dolly system in contact with a ground;
placing a cargo onto the holding surface; and
propelling the folding dolly system to transport the cargo.

15. The method of claim 11 further comprising:
sending a second connector through a number of knuckles of a first edge of a second base unit and a number of knuckles of a second edge of the base unit to form a second joint of the folding dolly system, wherein forming the second joint of the folding dolly system increases a surface area of the holding surface of the folding dolly system.

16. A base unit for a folding dolly system, the base unit comprising:
a first edge having a number of knuckles for forming a joint, wherein each of the number of knuckles is configured to receive a number of connectors, and wherein each of the number of knuckles is connected to a bottom of the base unit such that each of the number of knuckles is positioned beneath a surface of the base unit and beneath the bottom of the base unit;
a second edge having a second number of knuckles for forming a joint, wherein each of the second number of knuckles is configured to receive a number of connectors, and wherein each of the second number of knuckles is connected to a bottom of the base unit such that each of the second number of knuckles is positioned beneath a surface of the base unit and beneath the bottom of the base unit; and
the surface between the first edge and the second edge, the surface is substantially planar.

17. The base unit of claim 16 further comprising:
a wheel connected to a bottom of the base unit.

18. The base unit of claim 16 , wherein a remainder of the first edge is configured to react against a second base unit to provide a substantially planar holding surface of the folding dolly system, the second base unit forming the joint with the number of knuckles.

19. The base unit of claim 16 , wherein the number of knuckles of the first edge is configured to support a remainder of a second edge of a second base unit to provide a substantially planar holding surface of the folding dolly system.

20. The base unit of claim 16 , wherein a third edge and a fourth edge of the base unit are each substantially planar and substantially perpendicular to the surface.

21. A method comprising:
connecting a plurality of interconnectable base units to form a folding dolly system having a holding surface formed by a respective surface of each of the plurality of interconnectable base units, a plurality of joints connecting the plurality of interconnectable base units into a plurality of rows rotatably connected by the plurality of joints, and a plurality of wheels connected to the plurality of interconnectable base units, wherein the folding dolly system is configured to fold into the plurality of rows around an axis, wherein connecting the plurality of interconnectable base units comprises:
sending a number of connectors through knuckles of a first number of base units to form a first joint of the plurality of joints, the number of connectors comprising at least one of a number of sh
