The inventive stand-up umbrella consists of a standing pole (1) and an umbrella structure consisting of roof ribs (3) which are linked to a stationary end crown (2) and which are supported by support ribs (5). Said support ribs are linked to the roof ribs (3) by their top end and to a running crown (4), which is displaceable on the standing pole (1), by their bottom end. A pneumatic or steel draw spring (6) is located between the end crown (2) or the top end area of the roof ribs (3) near the end crown (2) and the outer area of the support ribs (5), respectively. These draw springs (6) perform a reinforcing function when the umbrella is being opened and a braking, damping function when it is being closed.
