A collapsible wagon comprises a frame, four wheels, a pliable liner, and a telescoping tow handle. The frame has four sides that are each formed by a respective scissor-bar assembly. The frame also has a vertically oriented telescoping pole assembly at the intersection of each pair of the scissor-bar assemblies. The frame is configured such that, as the wagon is altered from its expanded to its collapsed configuration, the scissor-bar assemblies and the telescoping pole assemblies increase in height and the scissor-bar assemblies decrease in width. Each of the four wheels is attached to a bottom end portion of a respective one of the telescoping pole assemblies. The pliable liner is connected to the frame and defines an open-top interior compartment of the wagon when the wagon is in its expanded configuration. The telescoping tow handle is adjustable between collapsed and expanded configurations. |

1. A method of collapsing a wagon, the wagon comprising a frame, a collapsible tow handle, and a pliable liner, the frame having four sides, each side being formed by a respective scissor-bar assembly, at least two of the scissor-bar assemblies each comprising two pairs of crossed-bars, the pairs of crossed-bars being connected to each other at a top-center portion and a bottom-center portion, the pliable liner defining an open-top interior compartment of the wagon when the wagon is in an expanded configuration, the frame also having a vertically oriented telescoping pole assembly at an intersection of each pair of the scissor-bar assemblies, the pliable liner being fixed to a top of each of the telescoping pole assemblies and comprising inverted pockets that receive the top-center portion of the at least two of the scissor-bar assemblies, the pliable liner also comprising four vertical corners that are attached to the telescoping pole assemblies beneath the tops of the telescoping pole assemblies, the method comprising:
adjusting the frame of the wagon from the expanded configuration to a collapsed configuration in a manner causing the scissor-bar assemblies and the telescoping pole assemblies to increase in height and the scissor-bar assemblies to decrease in width, the pliable liner being collapsed in the process. |
