A telescopic umbrella is provided; the umbrella has a telescoping umbrella stick, with a runner sliding thereon with stretchers running from the slide; at the outer ends of the stretchers are dome ribs, above each of which is located an auxiliary link running approximately parallel therewith, one end of each auxiliary link being hinged to a dome rib while the other end is hinged to a strut; the strut running, when the umbrella is in an open configuration, obliquely upwards from the stretcher towards the umbrella stick, and a control link running from each stretcher approximately parallel with an inner dome rib part, the outer end of the control link serving to control the folding motion of the outer dome rib part in dependence on the movement of the umbrella runner. |
