Abstract: An umbrella member includes a slide slidably mounted about a tubular support shaft. The shaft includes a collar thereon, with the collar including plural pairs of canopy ribs pivotally mounted to the collar, with each of the canopy ribs including a slide housing slidably mounted to the ribs, with each slide housing including support ribs mounted to the slide housing and to the slide. The canopy ribs include a canopy member secured thereto, wherein the slide is arranged in cooperation with the slide housings to reverse the arcuate orientation of the canopy ribs to effect reversal of orientation of the canopy ribs from a downward to an upward position permitting ease of access of the umbrella structure within a limited environment, such as an automotive vehicle.
