An umbrella frame includes a hub, a center pole coupled to the hub for supporting the hub, and a plurality of ribs disposable into the hub. The ribs serve to extend, stretch or support the cover. The hub has a corresponding plurality of pairs of bores defined therein. One of the bores of each pair is used for deploying the ribs in a configuration to support the cover and the other for storing the ribs. One of the bores of the pair is inclined relative to a horizontal plane defined by the hub, and the other is vertical to a horizontal plane. Each rib has an end disposable into the hub and a spring lock to selectively lock into the hub. The pair of bores coact with the spring lock to selectively lock the rib in the bores in both the deployment and storage configurations.
