Abstract
A foldable wagon has a frame with vertical members arranged at four corners of the frame. Each vertical member has an upper bracket, a lower bracket, and a sliding member slidingly disposed on the vertical member between the upper and lower brackets. The frame has first bottom members with inner ends pivotally connected together with a first bottom connecting member and outer ends operatively and pivotally connected to a respective sliding member. The frame has second bottom members with inner ends operatively and pivotally connected together with a second bottom connecting member and outer ends being operatively and pivotally connected to a respective lower bracket.

A foldable wagon comprising a frame, the frame adapted and configured to be moved between an expanded configuration and a folded configuration, the frame comprising vertical members arranged at four corners of the frame, each of the vertical members having an upper bracket on one end of the vertical member, a lower bracket on an opposite end of the vertical member, and a sliding member slidingly disposed on the vertical member between the upper and lower brackets, the frame further including first bottom members, each of the first bottom members having inner ends and opposite outer ends, the inner ends of the first bottom members being operatively and pivotally connected together with a first bottom connecting member, the outer ends of the first bottom members being operatively and pivotally connected to a respective sliding member, the frame further including second bottom members, each of the second bottom members having inner ends and opposite outer ends, the inner ends of the second bottom members being operatively and pivotally connected together with a second bottom connecting member, the outer ends of the second bottom members being operatively and pivotally connected to a respective lower bracket.
A wagon that is adjustable between an expanded configuration and a collapsed configuration, the wagon comprising:
- a frame, the frame having four sides, each side being formed by a pair of folding bar assemblies, the pair of folding bar assemblies of each side of the frame having opposite upper leg outer ends and opposite lower leg outer ends, the frame also having a vertically oriented pole at an intersection of the pair of folding bar assemblies of one side with the pair of folding bar assemblies of an adjacent transverse side, the upper leg outer end of each of the pair of folding bar assemblies being operatively connected to the vertically oriented pole, the lower leg outer end of each of the pair of folding bar assemblies being operatively slidingly connected to the vertically oriented pole, wherein when the wagon is in the expanded configuration, each of the lower leg outer ends of the pairs of folding bar assemblies has a first distance to each of the corresponding upper leg outer ends of the pairs of folding bar assemblies along the respective vertically oriented poles, wherein when the wagon is in the collapsed configuration, each of the lower leg outer ends of the pairs of folding bar assemblies has a second distance to each of the corresponding upper leg outer end of the pairs of folding bar assemblies along the respective vertically oriented poles, the second distance of each of the respective upper and lower legs outer ends is greater than the first distance of each of the respective upper and lower legs outer ends, the frame further comprising a collapsible bottom support assembly, the bottom support assembly comprising a central hub and four bars, the four bars are each operatively pivotally connected to the central hub and operatively pivotally connected to the bottom end portion of a respective one of the vertically oriented poles, the frame further comprising a collapsible upper support assembly, the upper support assembly comprising a central hub and four bars, the four bars are each operatively pivotally connected to the central hub and operatively pivotally and slidingly connected to a respective one of the vertically oriented poles.
A wagon that is adjustable between an expanded configuration and a collapsed configuration, the wagon comprising:
- a frame, the frame having four sides, each side being formed by a pair of folding bar assemblies, the pair of folding bar assemblies of each side of the frame having opposite upper leg outer ends and opposite lower leg outer ends, the frame also having a vertically oriented pole at an intersection of the pair of folding bar assemblies of one side with the pair of folding bar assemblies of an adjacent transverse side, the upper leg outer end of each of the pair of folding bar assemblies being operatively connected to the vertically oriented pole, the lower leg outer end of each of the pair of folding bar assemblies being operatively slidingly connected to the vertically oriented pole, the frame being configured and adapted such that as the wagon is altered from the wagon's expanded configuration to the wagon's collapsed configuration, the lower leg outer end of each of the pair of folding bar assembly slides downward relative to the corresponding upper leg outer end of the pairs of folding bar assemblies on the respective vertically oriented pole, and the pairs of folding bar assemblies increase in height and decrease in length, the frame being configured and adapted such that as the wagon is altered from the wagon's collapsed configuration to the wagon's expanded configuration the lower leg outer end of each of the pair of folding bar assembly slides upward relative to the corresponding upper leg outer end of the pairs of folding bar assemblies on the respective vertically oriented pole, and the pairs of folding bar assemblies decrease in height and increase in length;
- the frame further comprising a collapsible bottom support assembly, the bottom support assembly comprising a central hub and four bars, the four bars are each operatively pivotally connected to the central hub and operatively pivotally connected to the bottom end portion of a respective one of the vertically oriented poles, the frame further comprising a collapsible upper support assembly, the upper support assembly comprising a central hub and four bars, the four bars are each operatively pivotally connected to the central hub and operatively pivotally and slidingly connected to a respective one of the vertically oriented poles.
