Abstract: An umbrella frame is described having dome ribs, each including an inner section, a telescopic middle section, and an outer section hingedly connected to the middle section for movement between a position colinear with the middle section and a position with the outer section folded over the middle section. A geats is slidable on the inner section, and a stretcher member is hinged to the main runner as well as to the geats. A second geats member is slidable on the inner section and is connected to the end of the middle dome rib section. An auxiliary runner is slidable on the stick between the main runner and the crown. A strut member is hinged to the auxiliary runner and to the stretcher member, and a control link is hinged to the stretcher member, a short distance from the hinge of the first geats, and at the other end the control link member is pivotally connected to an inner extension of the outer dome rib section.

Abstract: 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.
