发明名称 Collapsible safety sign
摘要 A safety sign is provided which includes a collapsible tripod base that removably supports a hollow tube therein. The hollow tube stores a foldable fabric sign therein which includes pockets at the upper, left and right corners thereof and defines a mast for the sign. The sign is supported on the base by a vertical support rod and includes a horizontal cross member. The horizontal cross member is twistable independently of the base and mast wherein this free-floating arrangement facilitates assembly of the sign while also permitting the sign to twist during windy conditions and allow the wind to spill around the sign in order to prevent the sign from toppling over.
