Abstract: An umbrella comprising an umbrella shaft (1) and an umbrella frame situated on the umbrella shaft (1), the frame comprising a spider that is formed by umbrella ribs and supports a canopy, and spreader struts that are pivoted on the umbrella ribs and on a slider (2) that is supported so as to be longitudinally displaceable on the umbrella shaft (1) between a closed position and an open position of the umbrella frame. The slider (2) has at least two locking elements (3), each provided for engagement in a lock seat (4) associated with the umbrella shaft in the particular end position of the slider (2), and a handle (5) that is axially displaceable between two end positions is provided on the slider (2). The handle is forcibly entrained from one end position to the other when the slider is actuated, and the locking element (3) that is engaged is shifted to an unlocked state and the other locking element (3) is shifted to a locked state that allows engagement in the other lock seat (4).
