Umbrella frame

摘要

An umbrella frame comprises a plurality of main ribs attached to a slidable moving plate assembly by a plurality of support ribs. A plurality of stabilizing ribs are secured to the support ribs. The stabilizing ribs are further secured to a stationary plate assembly in a manner which permits the main ribs to open by gravity thus resulting in an umbrella frame whose relaxed state is open. An upper plate assembly is secured to the umbrella frame pole by an energy absorbing and dissipating means to stabilize the umbrella in windy conditions.
