Folding wagon

1. A folding wagon comprising:

• a. a folding frame having a stowed position and an open position;
  
  wherein the folding frame comprises a pair of front and rear vertical support, a front upper horizontal support extending between the pair of front vertical supports, a rear horizontal support extending between the pair of rear vertical supports, and a pair of lower horizontal support, namely a front lower horizontal support extending between the pair of front vertical supports, and a rear lower horizontal support extending between the pair of rear vertical supports;
  
  wherein the folding frame further comprises a pair of front supplemental links and a pair of rear supplemental links, wherein the pair of front supplemental links are pivotally connected to diagonal folding members, wherein the pair of rear supplemental links are pivotally connected to diagonal folding members, wherein the pair of front supplemental links are pivotally connected to the pair of front vertical support, wherein the pair of rear supplemental links are pivotally connected to the pair of rear vertical supports, wherein the diagonal folding members form a first leaning connection against the pair of front vertical supports, and wherein the diagonal folding members form a second leaning connection against the pair of rear vertical supports;
  
  b. a fabric bed having rigid bottom panels, wherein the fabric bed has a front fabric wall, a rear fabric wall, and a pair of substantially parallel sidewalls;
  
  c. a plurality of flatbed supports forming a central flatbed support joint in the middle of the wagon, wherein the central flatbed support joint folds upward when the folding frame is being configured into stowed position, wherein the plurality of flatbed supports are pivotally connected to the pair of front vertical supports and the pair of rear vertical supports; and
  
  d. wheels attached to the folding frame,wherein the diagonal folding members form a pair of diagonal folding member apparatus, each diagonal folding member apparatus forming a left and right side wagon wall respectively, wherein each wagon wall comprises four diagonal folding members, namely a first diagonal folding member, a second diagonal folding member, a third diagonal folding member, a fourth diagonal folding member, wherein the first diagonal folding member and the second diagonal folding member are connected to the third diagonal folding member and a fourth diagonal folding member at an upper major pivot and a lower major pivot, wherein the lower major pivot is a pivot connection between the first diagonal folding member and the fourth diagonal folding member, wherein the diagonal folding members connect to a front leaning bar which leans against the pair of front vertical supports to forms a front leaning connection against the pair of front vertical supports, wherein the diagonal folding members connect to a rear leaning bar which leans against the pair of rear vertical supports to form a rear leaning connection against the pair of rear vertical supports.
