Abstract
Abstract A collapsible, triangular frame is placed on the back side of an automobile to be used as a "disabled" sign when the automobile breaks down. The triangular frame is composed of a base member and two side members rotatably connected to two ends of the base member. A driving device operable by a control device is provided onto the base member to operate the two side members from a horizontal position to an erected position, and from the erected position to the horizontal position, as desired. The triangular frame is provided with signal lights which are turned on when the triangular frame is erected, and are turned off when it is collapsed to the horizontal position.
