Abstract
An umbrella includes a number of strut assemblies each having a beam and a spring rod pivotally coupled between a strut and a rib. The spring rod includes a middle portion slidably coupled to the beam. A pole is slidably secured to the beam and coupled to the middle portion of the spring rod. For example, the pole includes an aperture for receiving the middle portion of the spring rod and for allowing the middle portion of the spring rod to be loosely coupled to the beam and for preventing the spring rod from being bent or damaged by the beam.
