Abstract: A control device is applied to a base of an umbrella stem. A buckle sits in the base whose upper portion sets a controlling device controlled by the buckle and whose lower portion radially disposes a spool disk. The peripheral wall of the spool disk having ratchets defined thereon is embraced by a spool groove. Two ends of a spiral spring are respectively fixed to the base and the spool disk to generate an elastic force driving the spool disk's rotation. A shift block positioned under the base of the controlling device has a continuous torsion to contact the spool disk and clasp the ratchets. A disk cord provides one end fixed on the spool disk and wound around the spool groove and the other end penetrating the controlling device and the base to join an upper accommodation of the umbrella.

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. When the umbrella tie band is not unfastened and the pushbutton is incidentally triggered, the lower runner spring which has a greater elastic force than a control ring spring will prevent the clip leg from reaching the position of the latch element, and the umbrella will not be extended or retracted immediately. Thus the umbrella can be prevented from extending by incidental triggering of the pushbutton.
