ABSTRACT:
A suspension umbrella has a crown connected to a holder by means of a ball joint. For arresting the ball joint in different positions the ball joint is equipped with an arresting body which is actuatable by means of a screw spindle arranged coaxially to the umbrella axis. A securing device includes a securing screw which is threaded into the crown through a bore in a sleeve in order to prevent relative movement between the crown and the sleeve or ball joint.
