Claim 0:
1. A folding frame comprising:
a handle portion comprising a first upper rack member interconnected to a first lateral aspect of the handle portion, wherein the first upper rack member is intermeshed with a first pinion;
the handle portion further comprising a second upper rack member interconnected to a second lateral aspect of the handle portion, wherein the second upper rack member is intermeshed with a second pinion;
a wheelbase comprising a first lower rack member interconnected to a first lateral side of the wheelbase, wherein the first lower rack member is intermeshed with the first pinion angularly offset from the first upper rack member;
the wheelbase further comprising a second lower rack member interconnected to a second lateral side of the wheelbase, wherein the second lower rack member is intermeshed with the second pinion angularly offset from the second upper rack member;
a first housing statically interconnected to the first pinion wherein the first pinion is configured to rotate in relation to the first housing, and wherein the first upper rack member and the first lower rack member are configured to move longitudinally in relation to the first housing;
a second housing statically interconnected to the second pinion wherein the second pinion is configured to rotate in relation to the second housing, and wherein the second upper rack member and the second lower rack member are configured to move longitudinally in relation to the second housing;
a plurality of wheels interconnected with the wheelbase configured to allow the rolling of the folding frame along a surface when the folding frame is in an unfolded configuration;
wherein the extension of one of the handle portion and the wheelbase away from the pinions, results in the movement of both the handle portion and the wheelbase in opposing directions away from the first pinion, thus resulting in extension of the folding frame into the unfolded configuration, and
wherein the movement of one of the handle portion and the wheelbase toward the pinions, further results in the movement of both the handle portion and the wheelbase in opposing directions toward the first pinion, thus resulting in the collapsing of the folding frame into a folded configuration.
