Claim 7

said right and said left upstanding wall including in series an integrally connected forward wall, side wall and rear wall, respectively; e. said left and said right base hingedly mounted to said center portion base left and right side, respectively, and f. whereby upon folding of said wheelbarrow, successively said fork with wheel is adapted to fold underneath said base, said handle-leg assemblies next to each side of said folded fork and, thereafter, said forward center section, said rearward center section, said left and said right base downward from said center base, said left and right portion upstanding walls against said down folded left and right base so that said left portion telescopes into said right portion and a substantially rectangularly shaped box is formed.

Claim 8

said right and said left upstanding wall including in series an integrally connected forward wall, side wall and rear wall, respectively; e. said left and said right base hingedly mounted to said center portion base left and right side, respectively, and f. whereby upon folding of said wheelbarrow, successively said fork with wheel is adapted to fold underneath said base, said handle-leg assemblies next to each side of said folded fork and, thereafter, said forward center section, said rearward center section, said left and said right base downward from said center base, said left and right portion upstanding walls against said down folded left and right base so that said left portion telescopes into said right portion and a substantially rectangularly shaped box is formed.

Claim 9

A foldable wheelbarrow comprising: a. a horizontally disposed base member; b. a fork, carrying a rotationally mounted barrow support wheel, pivotally mounted to said base about a transverse horizontal axis; c. a pair of foldable handle-leg assemblies pivotally mounted to said base about laterally spaced vertical axes; d. a segmented carrying means comprising a right, a left and a center portion;

Claim 10

A foldable wheelbarrow comprising: a. a horizontally disposed base member; b. a fork, carrying a rotationally mounted barrow support wheel, pivotally mounted to said base about a transverse horizontal axis; c. a pair of foldable handle-leg assemblies pivotally mounted to said base about laterally spaced vertical axes; d. a segmented carrying means comprising a right, a left and a center portion;

Claim 11

A foldable wheelbarrow as claimed in claim 4 wherein about a horizontally extended axis: a. said fork member having a pair of ends; b. journal axle means mounted at said ends, and c. a wheel carried by said journal means for rotation and support of said wheelbarrow.

Claim 12

A foldable wheelbarrow as claimed in claim 5 wherein each said handle-leg assembly comprises: a. a container support linkage mounted for pivoting about respective one of said vertical axes at one end and having an intermediate first pivot means and a second pivot at said container support linkage other end; b. a handle linkage having handle means at one end, a third intermediate pivot means and connected pivotally to said second pivot means of said container support linkage at its other end; c. a first and a second leg support linkage connected to one another end by a fourth pivot means and said first leg support linkage other end pivotally connected tO said container support linkage second pivot means and said second leg support other end pivotally connected to said handle linkage third pivot means, whereby upon folding of said handle-leg assembly said first, second, third and fourth pivot means pivot about horizontal axes and said second and fourth pivot means move away from one another.

Claim 13

A foldable wheelbarrow as claimed in claim 6 wherein said right and said left handle linkage and said right and said left upstanding rear wall are respectively provided with holding means for positioning and engaging said right handle linkage means with said right upstanding rear wall and said left handle means with said left upstanding rear wall at a predetermined fixed location so that said right and left handle means are spread at proper position from one another.

Claim 14

A foldable wheelbarrow as claimed in claim 7 wherein said right forward and right rear upstanding wall and wherein said left forward and left rear upstanding wall have substantially vertical edges which are complementing with said center base forward center section and said rear center section vertical edges respectively, and wherein said complementing edges are provided with flange means for achieving a multi-surface abutting and closing relationship.
