ABSTRACT:
A multi-purpose automatically rewindable sun-shade devised to have a quite long resilient curtain which is wound around a winding tubular shaft when it is not in use. The curtain may be pulled out to a needed length for use and rewound automatically on the winding shaft by twisted coil springs. The sun-shade comprises an elongated winding tubular shaft for winding a long curtain thereon, two immovable rods adapted to extend in the interior of the winding shaft, two coil springs fitting around the immovable rods in the winding shaft to generate tension when twisted. The tension force rotates the winding shaft to rewind the curtain after use. The shade has two sleeves assembled around the winding shaft and forming a central through hole for a square end of each of the immovable rods to pass through to engage a central square hole in each of two shaft caps assembled with the two sleeves so that the sleeves and the winding shaft can rotate together between the two shaft caps. An elongated semi-circular plate is assembled with the two shaft caps to cover and protect the winding shaft and the curtain wound thereon.
