  • Patent number: 5640984
    Abstract: A garden umbrella employing an upper canopy extending from the top of the umbrella pole to the middle of long canopy ribs, and a lower outer canopy extending in a ring around the outer part of the umbrella and having long sleeves sewn across the canopy in a radial pattern for receiving a canopy rib in each sleeve. The canopy ribs are pivotally connected to a runner notch, while the other ends of the canopy ribs are received in the canopy sleeves. Stretcher ribs are pivotally connected between each canopy rib and a top ribholder secured at the top of the umbrella pole. The rib and runner notch configuration, together with the outer canopy, permit very easy opening and closing of the umbrella by movement of the runner notch between its upper, open umbrella position and its lower, closed umbrella position. The lower canopy comprises panels sewn together along the bottom of each rib such that a wind vent space is formed with the upper canopy which extends to the top of each rib.
