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 coiled spring plate is resiliently wound around a spool member which is rotatably mounted within the hollow housing. One end of the coiled spring plate passes through each of the blades and connects to a plate member that is capable of being biasingly retained over the hollow housing by the coiled spring plate when the plurality of blades is folded into the hollow housing in an accordion-like fashion. A brake is mounted in the hollow housing for engaging the spool member and preventing the same from rotating. A method for shielding the sun which includes grasping the plate member, after the brake has been released from engagement with the spool 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; and subsequently imposing the brake against the spool member to prevent the same from rotating and to maintain the extension of the desired length of plural blades away from the hollow housing.
