ABSTRACT:
A collapsible sun shade having plural pleated blades consecutively joined in series to form a serrated shape with an upper blade mounted within a hollow housing and a lower blade secured to a plate member. A constant force spring plate is resiliently wound around a spring spool member and further engaged to an output spool, both of which spools being rotatably mounted within a hollow handle secured to the hollow housing. One end of a cord is connected to the output spool and the other end passes from the handle and into the housing and through each of the blades and connects to a plate member that is capable of being biasingly retained over the hollow housing by the constant force spring plate when the plurality of blades are folded into the hollow housing in an accordion-like fashion. A method for shielding the sun which includes grasping the plate member and pulling the plate member away from the hollow housing until a desired length of plural blades has been presented for sun shielding purposes.
