Abstract: A semi-automatic umbrella includes a telescopic central shaft, a handle, and a runner slidable along the shaft. A first pull cord is placed in a tensed state when the shaft is extended, which causes an upward biased movement of an actuating member to thrust a spring-biased runner-retaining member to disengage from the shaft once the first pull cord is released. A tension spring body coupled to a second pull cord is stretchable to acquire an urging force. The stretched tension spring body enables an upward movement of the runner for spreading the umbrella. Once the urging force is released, a downward movement of the runner causes collapse of the umbrella and disengagement of a spring-biased shaft-retaining member from the shaft, thereby permitting folding of the shaft and closing the umbrella.
