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.
