A support frame for a cart canopy and a method of supporting a cart canopy are shown. The support frame may have a pivotable support bar and a foundation bar. The foundation bar may be connected to the support bar so as to allow the support bar to pivot from the foundation bar. The foundation bar may have a first end and a second end, wherein the first end has a first curved portion to which a first end of the pivotable support bar may be attached. The first end of the foundation bar may have a first step portion positioned proximate to the first curved portion, and the first step portion may be oriented to raise the elevation of the first end.
