Abstract

Compactible wagons are provided having at least two operational configurations. The compactible wagon has a first unfolded configuration where the first and second set of wheels are spaced apart by a horizontal platform and at least a second compacted configuration where the horizontal platform is folded into a vertical configuration and the first and second set of wheels are disposed next to each other. The compactible wagon can have one or more additional configurations, including extended configuration where one or more additional sections are positioned to extend the surface area of the horizontal platform of the wagon. Many different rigid and flexible sidewalls may be used with the wagon.

First claim

The invention claimed is:

1. A compactible wagon comprising:
a platform having first and second ends and upper and lower surfaces and defining a platform width, a platform length and a longitudinal axis at either end of which are disposed the first and second ends of the platform, and where the platform is further comprised of at least two pivotably interconnected independent sections, at least one section being disposed proximal the first end and at least one section being disposed proximal the second end;
at least two sets of wheels, each of the at least two sets of wheels being disposed below the lower surface of the platform, at least one set being disposed on a bottom surface of each of at least the two independent sections proximal the first and second ends, and each set of wheels comprising at least one wheel;
wherein the independent sections of the platform are pivotable about a horizontal axis arranged perpendicular to the longitudinal axis between an unfolded position and a folded position, where in the unfolded position all of the independent sections form a platform having a horizontally planar configuration, and wherein in a folded position the independent sections are disposed vertically adjacent one another and concomitantly the at least two sets of wheels remain located below the folded platform and are drawn closer together such that at least one set of wheels partially overlaps the other set of wheels along a single axis, and wherein in the horizontally planar configuration the platform of the compactible wagon is substantially flat.

2. The compactible wagon of claim 1 , wherein the independent sections of the platform are pivotably interconnected at the midpoint of the platform length.

3. The compactible wagon of claim 1 , wherein the two sets of wheels overlap when the platform is disposed in the folded position.

4. The compactible wagon of claim 1 , wherein at least one set of wheels is rotatable about a vertical axis perpendicular to the longitudinal axis of the platform.

5. The compactible wagon of claim 4 , further comprising a handle interconnected to the at least one set of wheels that is rotatable about the vertical axis.

6. The compactible wagon of claim 1 , further comprising a least a third and a fourth independent section, wherein the at least third independent section is pivotably interconnected with the first end of the platform and the at least fourth independent section is pivotably interconnected with the second end such that the platform length is extended on the first and second end the length of each of the at least third and fourth independent sections.

7. The compactible wagon of claim 6 , further comprising at least one support element disposed at the first and second ends of the platform such that the third and fourth independent sections are supported in a horizontal plane that is the same as the horizontal plane of the platform and are prevented from rotating beyond the horizontal plane of the platform.

8. The compactible wagon of claim 6 , wherein the third and fourth independent sections are configurable to pivot to a vertical position such that they rotate about a horizontal axis that is perpendicular to the longitudinal axis of the platform.

9. The compactible wagon of claim 6 , further comprising at least two support brackets rotatably connected to the sides of the platform and configured to connect to each of the third and fourth independent sections such the support brackets provide a rigid support element for each of the third and fourth independent sections while in the vertical position.

10. The compactible wagon of claim 9 , wherein each of the at least two support brackets are disconnectable from the each of the third and fourth independent sections and secured in line with the horizontal plane of the platform.

11. The compactible wagon of claim 1 , further comprising at least two sidewalls rotatably connected to the platform and configured to span longitudinally along the length of the platform and wherein the at least two side walls can be rotated to a vertical position to form a partially enclosed volume above the platform, the sidewalls being further configured to fold such that in a compacted position no dimension of each of the sidewalls is greater than the width of the platform.

12. A compactible wagon comprising:
a platform having first and second ends and upper and lower surfaces and defining a platform width, a platform length and a longitudinal axis at either end of which are disposed the first and second ends of the platform, and where the platform is further comprised of at least two pivotably interconnected independent sections, at least one section being disposed proximal the first end and at least one section being disposed proximal the second end;
at least two sets of wheels, each of the at least two sets of wheels being disposed below the lower surface of the platform, at least one set being disposed on a bottom surface of each of at least the two independent sections proximal the first and second ends, and each set of wheels comprising at least one wheel;
wherein the independent sections of the platform are pivotable about a horizontal axis arranged perpendicular to the longitudinal axis between an unfolded position and a folded position, where in the unfolded position all of the independent sections form a platform having a horizontally planar configuration, and wherein in a folded position the independent sections are disposed vertically adjacent one another and concomitantly the at least two sets of wheels remain located below the folded platform and are drawn closer together such that at least one set of wheels partially overlaps the other set of wheels when viewed from the side, and wherein in the horizontally planar configuration the platform of the compactible wagon is substantially flat; and
a least a third and a fourth independent section, wherein the at least third independent section is pivotably interconnected with the first end of the platform and the at least fourth independent section is pivotably interconnected with the second end such that the platform length is extended on the first and second end the length of each of the at least third and fourth independent sections.
