Abstract
A foldable umbrella includes an elongate handle, a ferrule fixed on an upper end thereof, a runner sleeved slidably on the handle. Each of a plurality of rib assemblies includes elongated first, second and third ribs. The first rib has a first proximate end connected pivotally to the ferrule, a first distal end, a first pivot and a longitudinal slide slot. The second rib has second proximate and second distal ends, and a second pivot disposed adjacent to the second proximate end. The second pivot is connected pivotally to the first distal end of the first rib. The third rib has third proximate and third distal ends, and a third pivot connected pivotally to the second distal end of the second rib. A stretcher has a fourth proximate end connected pivotally to the runner, and a fourth distal end connected pivotally to the first pivot of the first rib. A first connecting member has a proximate end connected pivotally to the stretcher, a distal end connected pivotally to the second proximate end of the second rib, and a transverse projection extending through the slide slot of the first rib to connect pivotally with one end of a second connecting member.
