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.

Claims

1. In a system of folding table having a portion with means for engaging a pole of the type used substantially upright in supporting beach umbrellas, the improvement comprising:

the means for engaging a pole including a hub with a bore for receiving a pole, a plurality of spokes with inner and outer ends, means for attaching each inner end to the hub pivotally from a first position with the spokes radial to the bore to a second position with the spokes upward substantially parallel with the bore, a flexible-material member supported by the plurality of spokes and forming a disc shaped table-like surface with the plurality of spokes in said first position, means for releasibly affixing the plurality of spokes in said first position and means for releasibly affixing the plurality of spokes in said second position, the means for releasibly affixing the plurality of spokes in said first position comprising a threaded portion on the hub, a radial flange on the hub adjacent the threaded portion, a nut proportioned for screwing onto the threaded portion on the hub and clamping the plurality of spokes between the nut and the radial flange and means for resisting radial forces on the disc shaped table-like surface, including the flexible material member having an inner perimeter and said inner perimeter being clamped by the nut when the nut clamps the plurality of spokes, means for stabilizing the plurality of spokes when affixed in said first position comprising the flange having structure defining a plurality of radial grooves therein in position for receiving a portion of said plurality of spokes when clamped, means for stabilizing the plurality of spokes when affixed in said second position, comprising the hub having therein structure defining a plurality of notches parallel with the bore in position for receiving a portion of said plurality of spokes when in said second position, said flexible material member supported by the plurality of spokes including the plurality of spokes being within respective tunnels in the flexible-material member, and said flexible-material member being in the shape of a disk with a closed margin around the outer periphery guarding the outer ends of the spokes.

2. In a system as recited in claim 1, means including a threaded tubular lower end on the hub for storing the nut on the hub when the folding table is removed from the pole.

3. In a system as recited in claim 1, the means for engaging a pole further comprising the threaded portion having structure defining a plurality of slots therein leaving tongue-like portions between the slots, the nut having proportions such that when the nut is tightened on the threaded portion the tongue-like portions will deflect into the bore for gripping a pole as the nut accomplishes said clamping of the plurality of spokes.
