ABSTRACT:
A covering frame for supporting a canopy above a ground surface includes a plurality of legs adapted to extend uprightly from the ground surface, and a canopy support frame mounted on top of the legs. The canopy support frame includes at least one pair of parallel support rods having lower ends mounted on the legs and upper ends, an upper horizontal bar interconnecting the upper ends of the support rods, a lower horizontal bar parallel to the upper horizontal bar and interconnecting the lower ends of the support rods, and a supplementary canopy support member extending transversely between the support rods. The supplementary canopy support member includes a seat having two opposite mounting ends, and a pair of connecting wires having outer ends connected respectively to the support rods and inner ends mounted adjustably and respectively on the mounting ends of the seat. The seat is operable to result in lengthening and shortening of a distance between the outer ends of the connecting wires, thereby permitting adjustment of the distance between the outer ends of the connecting wires to be equal to a distance between the support rods.
