Rib assembly capable of being telescopically packed for outdoor umbrella and outdoor umbrella

Abstract

A rib assembly for an outdoor umbrella is capable of being telescopically packed. The rib assembly includes a longer rib and a shorter rib. When the rib assembly needs to be disassembled for packing, the longer rib or/and the shorter rib is able to be superimposed and retracted along a length direction. A locking mechanism is disposed on the longer rib or/and the shorter rib. When the rib assembly needs to be extended completely, the longer rib or/and the shorter rib are locked by the locking mechanism.
