A condensed retractable traffic cone is a device designed to provide motorists with advance warning of disabled vehicles and/or work zone areas. The device has been designed to withstand reasonable winds through the use of two base supports, a lower portion, a retractable arm and a series of retractable vertical risers. The retractable vertical risers in combination with a retractable arm allow for the device to easily expand to height consistent with traffic engineering design standards when in operation and then compact when it is in storage. The two base supports are designed not only to provide the necessary structural stability but to also open and close about the retractable vertical risers thus providing for additional compactness. The vertical risers are designed with flexible hinges so that they may store flat and expand to a rectangular shape when the base supports are rotated to an open position, accomplished a by linkage connecting the lower vertical riser and the base supports.

What is claimed is: 1. A condensed retractable traffic cone, comprising: a lower portion comprised of a flat bottom section; a first and a second base support, each base support having a bottom with no top, two short sides and a long side, the short sides of the first base support foldable at a first position about the lower portion, and the short sides of the second base support foldable at a second position about the lower portion; a plurality of vertical risers comprised of at least two collapsible hollow vertical risers that fit within each other, each collapsible hollow vertical riser having a collapsed position and an expanded position; a lower riser of the at least two collapsible hollow vertical risers having a plurality of rotatable connections between the lower of the at least two collapsible hollow vertical risers and the first and the second base support; and an upper riser of the at least two collapsible hollow vertical risers being extendable from the lower riser of the at least two collapsible hollow vertical risers, wherein when the base supports are in an unfolded open position, the at least two collapsible hollow vertical risers are maintained in the expanded position due to a pulling force of the base supports on the lower riser of the at least two collapsible hollow vertical risers through the connections, and when the base supports are in a folded closed position, the at least two collapsible hollow vertical risers are maintained in the collapsed position due to a pushing force of the base supports on the at least two collapsible hollow vertical risers. 2. The condensed retractable traffic cone of claim 1, wherein the rotatable connections are ball and socket connections. 3. The condensed retractable traffic cone of claim 1, wherein the upper riser of the at least two collapsible hollow vertical risers has a handle affixed to its top. 4. The condensed retractable traffic cone of claim 1, wherein the at least two collapsible hollow vertical risers are designed with air-flow holes. 5. A condensed retractable traffic cone, comprising: a lower portion comprised of a flat bottom section; a first and a second base support, the first base support foldable at a first edge of the lower portion and the second base support foldable at a second edge of the lower portion, the second edge being opposite to the first edge; a plurality of vertical risers comprised of at least two vertical risers that fit within each other, a lower riser of the at least two vertical risers, and an upper riser of the at least two vertical risers being extendable from the lower riser of the at least two vertical risers, each of said plurality of vertical risers having a collapsed state and an expanded state, and creating a volume area defined by said plurality of vertical risers; a retractable arm contained within the volume area and attached at a lower end to a top surface of the lower portion and at an upper end to a top of the upper vertical riser, wherein the first and second base supports are foldable about the plurality of vertical risers and enclose the plurality of vertical risers when the plurality of vertical risers are unextended and in a collapsed state. 6. The condensed retractable traffic cone of claim 5, wherein the upper riser of the at least two vertical risers has a handle affixed to its top. 7. The condensed retractable traffic cone of claim 5, wherein the at least two vertical risers are designed with air-flow holes. 8. The condensed retractable traffic cone of claim 5, wherein the retractable arm is connected to the lower portion via a spring-shaped element.
