ABSTRACT:
An automatic umbrella includes: a central shaft having a lower tube and an upper tube telescopically engageable with each other, a rib assembly pivotally connected to the central shaft having a lower runner slidably held on the central shaft, an opening spring retained in the central shaft, a control device installed within the grip of the central shaft without protruding any acute portion of the control device for safety purpose, and a drag device including a rod and a rope connected to each other to be retained between a lower portion of the lower tube and the lower runner slidably held on the central shaft, whereby upon actuation of the control device, the upper tube will be extended above the lower tube by the opening spring and the rib assembly may also be upwardly outwardly extended as dragged by the rope and the rod of the drag device for opening the umbrella, with the upper tube slidably telescopically engageable with the lower tube without forming any joint at the coupling location where the upper and lower tubes are slidably coupled, thereby thinning the upper and lower tubes for a lightening umbrella.
