Abstract: An automatic close umbrella is disclosed. As the umbrella is to be folded, the user only needs to press an elastic control device on a handle by one finger so that a tenon is released from a buckle and thus the buckle unit of the lower rib collector is separated with the lower sub-bar. Furthermore, the lower rib collector descends due to the elasticity of the upper rib collector and lower rib collector so as to impact the hook device of the sub-bar. Thereby, two sub-bars are separated and the hook device of each sub-bar will release. Therefore, each multi-sectional bar is telescopic automatically. Furthermore, as the ribs are folded, the canopy will be closed. Thus, as the user enters into a room or a car, the user may close the umbrella easily by only one hand.

Abstract: A control mechanism for folding jump umbrellas includes a composite control ring, a lower runner having a step opening at one end for housing a lower runner spring and a sleeve and a square opening engageable with a latch stub of a pushbutton. When the pushbutton is depressed, the square opening will be separated from the latch stub to allow the umbrella frame extending under the force of an extension spring. To retract the umbrella, depress a clip leg to move a latch element away from the harness of an elastic latch strip, the umbrella may be retracted by a retracting spring.
