A retractable safety marker 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 retractable support element and a partially reflectorized casing made from a porous cloth or nylon type material. The retractable arms 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 support element thus providing for additional compactness.

1. A retractable safety marker comprising: two separate base supports that are rectangularly shaped, each base support having a bottom with no top, two long sides and one short side, the long sides of the base support containing a combination of a hole in its upper portion and a slot in its lower portion on the side adjacent to the open side of each base support, a retractable support element comprised of an upper portion which has a continuous indentation encircling its width, two retractable arms, a lower portion including a continuous indentation encircling the base of the two retractable arms and two upper and two lower protruding tabs at each side, the upper protruding tabs of the retractable support element being inserted into the holes of the upper portions of the base supports, thereby permanently attaching the two base supports to the retractable support element, a semi-rectangular shaped casing made of a porous material, with a rubber-band type element affixed within its upper and lower ends; the casing being fitted over the retractable support element; the upper and lower ends of the casing being inserted into the continuous indentations of the upper and lower portions of the retractable support element; wherein the compressive force of the rubber-band type elements of the upper and lower ends of the casing holds the casing affixed to the upper and lower portions of the retractable support element. 2. The retractable safety marker of claim 1, wherein the retractable support element is constructed by connecting the two retractable arms into pre-made holes in the upper and lower portions of the retractable support element by press-fit. 3. The retractable safety marker of claim 1, wherein the retractable support element is constructed by connecting threaded ends of the retractable arms into pre-made threaded holes in the upper and lower portions of the retractable support element. 4. The retractable safety marker of claim 1, wherein the casing attaches to the upper and lower portions of the retractable support element by use of VELCRO.RTM.. 5. The retractable safety marker of claim 2, wherein the casing attaches to the upper and lower portions of the retractable support element by use of VELCRO.RTM..
