An umbrella frame includes an upper shaft part 2 and a lower shaft part 1, the two parts being connected by a tilting joint to enable the upper part to tilt with respect to the lower, a runner 4 sliding on the lower shaft part 1, for spreading a cover on the umbrella frame into its unfurled configuration when slid upwardly, and an actuator connected to the upper shaft part 2 and passing down the shaft, through or past the runner 4 when in its upper position with the umbrella open, to an operating location on the lower shaft part 1, the actuator being accessible at its lower end to allow an operator to tilt the upper shaft part 2. The upper cranked end of the rod 6 extends out through a slot 20 in the lower shaft part 1 and the body of the rod 6 extends axially downwards inside the lower shaft part 1 to an operating location where the lower end of the rod 6 is likewise bent outwards to extend through a second slot 21 in the lower shaft so as to be accessible to an operator who can apply force directly. To make the tilting operation still more convenient, a lever mechanism is provided in the form of sleeve 14 surrounding the shaft, having an internal recess in the form of a helical screw 15 into which the lower end of the rod 6 engages. Rotating the sleeve 14 will tilt the upper shaft part 2 of the umbrella frame.
