Abstract: Radially disposed ribs for supporting the canopy of an umbrella are pivotally connected by a crown mounted on the outer end of a rod. A sleeve is in external sliding relationship with the rod. Struts are pivotally connected to the sleeve, each strut being associated with one of the ribs for splaying the ribs and collapsing them inwardly. A support tube is connected by a coaxial shaft to the rod, and the sleeve is telescopically received in the support tube. The shaft is threaded and rotated by motor, opposing ends of the threaded shaft being supported for rotation in first and second journals fixed within the support tube and the rod, respectively. A threaded nut fixedly connected to the sleeve is engaged with the threaded shaft for moving the sleeve along the rod between extended and retracted positions.

Abstract: A winch for opening and closing an umbrella includes a winch drum mounted within an elongate support tube of the umbrella, to rotate about a longitudinal axis thereof. A threaded shaft is coaxial and rotationally fast with the drum. A line is fixed at one end to the drum and at other end to a sleeve, to which struts are pivotally connected, each strut being associated with a canopy-supporting rib. A travelling nut is engaged with the threaded shaft and blocked for rotation relative to the tube. A guide is fixed to the nut for guiding the line onto the drum, and a motor is also enclosed in the support tube and drivingly connected to the winch drum.
