Abstract: A retractable cylindrical safety marker is provided. The retractable cylindrical safety marker includes a base, having a middle section defining an upper planar surface and two opposing edges; a first end section rotatably attached at an end to one of the opposing edges; and a second end section rotatably attached at an end to the other of the opposing edges, and a vertical riser, having a lower riser having a lower end attached to the first end section and the second end section, the lower riser having a slot extending along its interior surface in the longitudinal direction; and at least one upper riser concentrically positioned within the lower riser, the upper riser having a tab positioned on an outer surface thereof, the tab being mateable with the slot and configured to permit the tab to translate along the slot.

Abstract: 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.

Abstract: A triangular retractable safety marker is a device designed to provide motorists and motorcyclists 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 and two sets of lower, middle and upper risers. The risers allow for the device to easily expand to height consistent with traffic engineering design standards for triangles when in operation and then compact when it is in storage. The two base supports in are designed not only to provide the necessary structural stability but to also open and close about the retractable risers thus providing for additional compactness. The upper part of the lower portion along with the two sets of lower, middle and upper risers have reflective decals affixed to them to correspond with standard triangle design.

Abstract: An enhanced 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, several retractable horizontal stabilizers that fit through slots on the base supports and a series of retractable vertical risers. The retractable vertical risers 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 in combination with the retractable horizontal stabilizers 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.
