Abstract
A rocking road emergency warning sign which is simple of construction and practical of use comprises a main body, a base, a top cover and a warning sign in which said main body is a spiral-shaped body formed by a resilient thin metal plate, said spiral-shaped body can be uncoiled into a triangular cone shape, the top portion of which has holes for attaching the warning sign. In addition, reflective papers or paints can be applied to both sides of the thin metal plate for intensifying the warning effect when the main body is swaying in the wind. The base is a substantially flat plate having a magnet on its bottom for sticking onto the metal part of the car. Also, clipping device are available at the cover to latch the top cover with the base together for carrying and storing.
 
Claims
What is claimed is:

1. A car mounted or free standing rocking road emergency warning sign comprising a main body, a base and a top cover therefore said main body being a resilient thin metal ribbon wrapped with elastic polystyrene, so as to form an I-shaped in cross-section spiral-shaped body, said spiral-shaped body being normally coiled from top to bottom into a disk shape, and when the coiling pressure is released, said main body uncoils and bounces upward to form a cone shape that is triangular in cross-section; means for securing a lower portion of the uncoiled main body to said base, said base and said top cover covering said main body when said body is coiled, a bottom surface of said base having a magnet therein for attaching said sign to a metal part of a car, the top cover having a clipping device for locking the top cover to the base for carrying and storage.



Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an road emergency warning sign, particularly to a rocking emergency road sign that is handy to carry along and easy to store away.

2. Description of the Prior Art

There are many types of road emergency warning sign available nowadays. These emergency warning signs are generally classified into two categories: one of these is the cone-shaped body with orange reflective color, as shown in FIG. 5. The other one is the triangular-shaped road emergency warning sign, as shown in FIG. 6. Both of these two types of emergency warning road signs have their drawbacks: they are not easy to be carried around, hard to be stored away, poor visibility and the triangular-shaped body is breakable. These drawbacks are caused by the poor design of the physical shape. The cone-shaped warning sign is substantially sturdy as compare to the triangular sign, but it is also bulky and it cannot be disassembled for storage, as is shown in FIG. 5. The triangular road warning sign as shown in FIG. 6 is more fragile because of its edge connection. These two kinds of road warning signs are of the fixed shape and fixed height design, they are impractical to be used in bad weather and poor visibility situation.
