  • Patent number: 4584946
    Abstract: A folding table especially adapted for use with a central pole supporting it, as under a beach umbrella, has a central hub with provision for detachably mounting at any desired level on a pole and a radial array of spokes pivotally mounted on the hub and supporting as a table surface, a disk of flexible material. In use position the spokes are radially deployed and rest against an annular flange of the hub, where a nut on a threaded coaxial portion of the hub holds them. The hub can be mounted so that the spokes fold upward for storage, or the hub can be inverted so that the spokes fold downward for storage. In folded position the table can easily be carried separate from or with a pole. The table surface or disk of flexible material can be easily removed and replaced with the spokes in folded position.
