ABSTRACT:
An umbrella frame having a pair of mounting rings and frame members which are pivotally connected to each other and to the mounting rings. A frame member having an elongated rod with a notch. A joint assembly is attached to the elongated rod and includes laterally opposed connector halves which mate to form a sleeve over the elongated rod. The sleeve has an inner boss which fits within the notch in the elongated rod when the connector halves are mated over the elongated rod. A collar slides around the mated connector halves to clamp the connector halves together over the elongated rod and to retain the inner boss within the notch in the elongated rod. Strut frame members have an end joint assembly at each end. Rib frame members have an end joint assembly at their inner ends and midpoint joint assemblies at rib midpoints. A mounting ring having a mounting base with a ring of spaced and vertically extending teeth. The frame members are received between the teeth. The teeth radially retain the frame members within the mounting base by engaging the frame member pivot lugs. A mounting cap has radially extending spaced teeth which fit between the teeth of the mounting base to retain the frame members within the mounting base. A lower mounting ring slides along the umbrella shaft to form an umbrella runner.
