A carrying device uses a folding structural frame covered by a shell. The frame is configured with two rigid members, which are joined together by two pivotable joints. A two-part base piece attaches to the frame and creates a structural bottom for the bag, with the base supporting articles placed inside of the bag. The frame and base create support that enables the bag to stand upright on a flat surface. The shell is made from a soft, flexible fabric material. The assembly is capable of folding to a substantially flat position, with the frame members moving relative to one another around the pivotable joints, and the base folding in half and becoming substantially co-planar with the frame. A strap attaches to the device in multiple configurations, allowing the device to be carried in different ways.

1. A carrying device, comprising an assembly of: a first frame member and a second frame member, each said frame member quadrilaterally shaped, with the two said frame members pivotably joined together at approximately a midpoint of each of their vertical sections;a flexible shell that surrounds said assembly, said shell including at least one access opening, said flexible shell including pleats on at least one bottom edge of said shell, with a majority of said pleats unfolding and creating slack material to allow said shell to fold with said frame members when said frame members are folded to a substantially flat position;a two-piece base formed from a right base and a left base, with said right and left bases pivotably joined together along one joined edge of each, said right and left bases pivotably joined to said lower horizontal sections of said first and second frame members;said edges joining said right base and left base together including interlocking ridges, said ridges formed by at least three pairs of tabs. 2. The device of claim 1, in which said right base and said left base include diagonal structural ribs. 3. The device of claim 1, in which said frame members pivot and said right base and said left base fold along said joined edge such the device can fold to a substantially flat position. 4. The device of claim 1, in which said frame members are positioned inside said flexible shell. 5. The device of claim 1, in which said shell includes at least one cutout to form a carrying handle, with a top edge of said cutout spanned by a horizontal frame member. 6. The device of claim 1 in which horizontal sections of each said frame member form a rigid opening to the device's interior cavity. 7. The device of claim 1, in which said shell is removable from said first and second frame members. 8. A carrying device, comprising: a first frame member and a second frame member, each said frame member each said frame member quadrilaterally shaped, with the two said frame members pivotably joined together at approximately a midpoint of each of their vertical sections;a flexible shell that envelopes said assembly, said shell including an access opening, first and second loops, each said loop located at a bottom corner of said shell, and a plurality of guides located inside said shell;said flexible shell including pleats on at least one bottom edge of said shell, with a majority of said pleats unfolding and creating slack material to allow said shell to fold with said frame members when said frame members are folded to a substantially flat position;a strap with a first attachment mechanism on one strap end and a second attachment mechanism on said strap's opposing end;a two-piece base formed from a right base and a left base, with said right and left bases pivotably joined together along one joined edge of each, said right and left bases pivotably joined to said lower horizontal sections of said first and second frame members;said edges joining said right base and left base together including interlocking ridges, said ridges formed by at least three pairs of tabs. 9. The device of claim 8, in which said frame members pivot and said right base and said left base fold along their joined edge such the device can fold to a substantially flat position. 10. The device of claim 8, in which said first attachment mechanism attaches to said first loop, said second attachment mechanism attaches to said second loop, and a midpoint of said strap is foldably fastened to a carrying handle on said device, to form two backpack straps. 11. The device of claim 8, in which said strap passes through each said guide, and first and second attachment mechanisms are then attached to each other to form a shoulder strap. 12. The device of claim 8, in which said strap passes through each said guide, first and second attachment mechanisms are then attached to each other to form tote-style straps. 13. A carrying device, comprising an assembly of: a first frame member and a second frame member, each said frame member quadrilaterally shaped, with the two said frame members pivotably joined together at approximately a midpoint of each of their vertical sections;a flexible shell that surrounds said assembly, said shell including at least one access opening, said flexible shell including pleats on at least one bottom edge of said shell, with a majority of said pleats unfolding and creating slack material to allow said shell to fold with said frame members when said frame members are folded to a substantially flat position;a rigid one-piece base pivotably joined on one edge to a lower horizontal section of said first frame member, with an opposing edge that removably engages a lower horizontal edge of said second frame member. 14. The device of claim 13, in which said rigid one-piece base further includes a live hinge spanning the midsection of said one-piece-base, allowing said one-piece base to fold lengthwise.
