Abstract
Umbrella shaft for a hanging umbrella, having a shaft part (20,26) and a rope drive (22), which connects a slide (16) and a crown (8) of the umbrella, the slide and the shaft part being coupled axially to one another when the umbrella is open. In order to improve the operability, the rope drive is designed as a rope winch (22) which can be connected to the slide (16), the rope (28) running essentially coaxially with the axis of the umbrella shaft.
