ABSTRACT OF THE DISCLOSURE: A telescopic umbrella has a slider movable on a stick and has a canopy which supports forks to be opened and closed by the slider and which are provided in a star-shaped arrangement around a crown. The crown is fitted on the stick and around the slider. In each case a link parallelogram is actuated by a scissors lever drive for the control of the folding motion of peripheral canopy spokes. In order to enable the canopy supporting forks to be more stable in their middle region, which is sensitive to deformation or rupture, and in particular to make in more resistant to excessive strain by gusts of wind causing the canopy to turn inside out, a hinge, connecting the inner canopy strut to the control strut, in the open position of the umbrella canopy, lies adjacent to the diagonal of the link parallelogram and bears against the bottom edge of a supporting strut so that the link parallelogram appears as a flat triangular formation. This triangular formation has an obtuse outer angle (?), while the hinge of the link parallelogram, connecting the supporting strut to a short arm of the peripheral canopy spoke, adopts from above about the same distance from the diagonal as the hinge connecting the inner canopy strut to the control strut adopts from below.
