Claim 3

A folding cart according to claim 1 in which said means for preventing contact between said material and said wheels comprises brace means for preventing said frame members from being folded toward each other.

Claim 4

A folding cart according to claim 1 in which said means for preventing contact between said material and said wheels comprises collapsible brace means for preventing said frame members from being folded toward each other.

Claim 5

A folding cart according to claim 3 in which said collapsible brace means comprises a first element pivotally secured at one end to said first frame member and rotatable about an axis substantially parallel to the wheel axis and a second element pivotally secured at one end to said second frame member and rotatable about an axis substantially parallel to said wheel axis, said first and second elements being hinged together at an intermediate location between said frame members, and one of said first and second elements extending beyond the location at which said elements are hinged together and being adapted to contact, with its opposite end, the frame member to which the other of said first and second elements is pivoted, the length of said one of said first and second elements being such that said opposite end contacts the last-mentioned frame member only when said elements are moved slightly beyond their parallel condition in the unfolding direction.

Claim 6

A folding cart according to claim 1 in which said second frame member comprises means extending behind said rear wall in a direction perpendicular to said axis from the upper edge of said rear wall substantially to the location of said axis, said means of the second frame member being spaced laterally inwardly from the side walls.

Claim 7

A folding cart according to claim 5 in which said means for preventing contact between said material and said wheels comprises collapsible brace means for preventing said frame members from being folded toward each other, said collapsible brace means extending from said longitudinally extending means of the first frame member to the means of the second frame member which extends behind the rear wall of the scoop-shaped body, and said collapsible brace means being substantially between said wheels and said flexible sheet material when said body is in its opened condition.

Claim 8

A cart comprising: a scoop-shaped body of flexible sheet material, said body having an open front, a bottom wall, a rear wall, and side walls extending upwardly from the bottom wall; a pair of wheels rotatable on an axis located adjacent the intersection of said rear wall and said bottom wall; and frame means comprising a substantially rigid frame member extending substantially from the front edge of said bottom wall to said axis; said frame member comprising at least two rigid members extending longitudinally from the front edge of said bottom wall substantially to the location of said axis, and providing support for said bottom wall from the front edge to the rear of said bottom wall, said longitudinally extending means being spaced from each other and laterally inwardly from said side walls, in which each of said rigid members comprises a section extending laterally along the front edge of said bottom wall, and having a substantially rigid clamping member extending along said front edge from one side wall to the other forward of said section of each rigid member, said front edge of said bottom wall being clamped between said clamping member and said laterally extending sections.

Claim 9

A cart comprising: a scoop-shaped body of flexible sheet material, said body having an open front, a bottom wall, a rear wall, and side walls extending upwardly from the bottom wall; a pair of wheels rotatable on an axis located adjacent the intersection of said rear wall and said bottom wall; and frame means comprising a substantially rigid frame member extending substantially from the front edge of said bottom wall to said axis; said frame member comprising at least two rigid members extending longitudinally from the front edge of said bottom wall substantially to the location of said axis, and providing support for said bottom wall from the front edge to the rear of said bottom wall, said longitudinally extending means being spaced from each other and laterally inwardly from said side walls, in which each of said rigid members comprises a section extending laterally along the front edge of said bottom wall, and having a substantially rigid clamping member extending along said front edge from one side wall to the other forward of said section of each rigid member, said front edge of said bottom wall being clamped between said clamping member and said laterally extending sections.

Claim 10

A folding cart comprising: a scoop-shaped body of flexible sheet material, said body, when in an opened condition, having an open front, a bottom wall, a rear wall, and side walls extending upwardly from the bottom wall; frame means comprising a first substantially rigid frame member extending substantially from the front edge of said bottom wall to a pivot axis adjacent the intersection of said bottom and rear walls, and a second substantially rigid frame member extending substantially from said pivot axis at least to the upper edge of said rear wall; said first and second frame members being pivotally connected together at the location of said pivot axis, whereby the upper edge of said rear wall can be brought into close proximity to the front edge of said bottom wall; and said first frame member comprising means extending longitudinally from the front edge of said bottom wall substantially to the location of said pivot axis, and providing support for said bottom wall from the front edge to the rear of said bottom wall, said longitudinally extending means being spaced laterally inwardly from said side walls, and said second frame member comprising means extending behind said rear wall in a direction perpendicular to said pivot axis, from the upper edge of said rear wall substantially to the location of said pivot axis, said means of the second frame member being spaced laterally inwardly from the side walls and providing support for said rear wall; and a pair of wheels rotatably mounted on said frame means adjacent the intersection of said bottom and rear walls, said wheels being rotatable on an axis parallel to the pivot axis of said frame.

Claim 11

A folding cart comprising: a scoop-shaped body of flexible sheet material, said body, when in an opened condition, having an open front, a bottom wall, a rear wall, and side walls extending upwardly from the bottom wall; frame means comprising a first substantially rigid frame member extending substantially from the front edge of said bottom wall to a pivot axis adjacent the intersection of said bottom and rear walls, and a second substantially rigid frame member extending substantially from said pivot axis at least to the upper edge of said rear wall; said first and second frame members being pivotally connected together at the location of said pivot axis, whereby the upper edge of said rear wall can be brought into close proximity to the front edge of said bottom wall; and said first frame member comprising means extending longitudinally from the front edge of said bottom wall substantially to the location of said pivot axis, and providing support for said bottom wall from the front edge to the rear of said bottom wall, said longitudinally extending means being spaced laterally inwardly from said side walls, and said second frame member comprising means extending behind said rear wall in a direction perpendicular to said pivot axis, from the upper edge of said rear wall substantially to the location of said pivot axis, said means of the second frame member being spaced laterally inwardly from the side walls and providing support for said rear wall; and a pair of wheels rotatably mounted on said frame means adjacent the intersection of said bottom and rear walls, said wheels being rotatable on an axis parallel to the pivot axis of said frame.

Claim 12

A folding cart according to claim 8 in which said second frame member comprises at least two rigid members extending behind said rear wall in a direction perpendicular to said pivot axis, said rigid members extending at least from the upper edge of the rear wall substantially to the location of said axis, and being laterally spaced from each other and being spaced laterally inward from said side walls.
