Abstract

A folding cart is disclosed which has a forward section, a main section, and a rear section, along with forward and rear end rails and left and right side rails. The forward and rear portions of the left and right side rails fold to a coplanar position with the main portion of each respective side rail, while the forward and rear end rails fold down to a position coplanar with the forward section and rear section, respectively. The forward and rear sections may then be rotated to a position over the main section. The forward and rear sections each have mounted to their bottom surfaces a dual wheel assembly, each dual wheel assembly having a pair of wheels which may be folded to a position parallel to their respective forward or rear section. The forward dual wheel assembly is mounted to the front section of the folding cart a rotating pivot, while the rear dual wheel assembly is mounted directly to the rear section. Finally, a folding handle is provided which is attached to the forward dual wheel assembly. The handle, when folded, extends from the midpoint of the forward dual wheel assembly over the folded wheels to the rear of the folded cart and clasps to the rear of the folded cart.

Claims4

Dependent claims

A folding cart comprising:

a. a forward bed frame further comprising a left member, a right member, a forward member, a rear member, and a forward bed floor;
b. a middle bed frame further comprising a left member, a right member, a forward member, a rear member, and a main bed floor;
c. a rear bed frame further comprising a left member, a right member, a forward member, a rear member, and a rear bed floor;
d. a forward dual wheel assembly attached to the bottom of said forward bed frame by means for pivoting said forward dual wheel assembly with respect to said forward bed frame, further comprising a left wheel and a right wheel, with each of said wheels being rotatably connected at its transverse axle to said means for pivoting said forward dual wheel assembly by means for folding said wheels from a position substantially parallel with said lower frame to a position perpendicular to the plane of said lower frame;
e. a rear dual wheel assembly attached to the bottom of said rear bed frame, further comprising a dual wheel assembly further comprising a left wheel and a right wheel, with each of said wheels being rotatably connected at its transverse axle to said rear bed frame by means for folding said wheels from a position substantially parallel with said lower frame to a position perpendicular to the plane of said lower frame;
and
f. a folding handle attached to the forward surface of said forward dual wheel assembly;
wherein said rear member of said forward bed frame is rotatively attached to said forward member of said main bed frame by hinge means and wherein said forward member of said rear bed frame is rotatively attached to said rear member of said main bed frame by hinge means.
