ABSTRACT:
An improved four-section umbrella framework is provided. The framework includes an attachable flexible frame member having a small slot in the main frame member of the umbrella framework. A connector is positioned inside the main frame member such that the latch ring of the connector protrudes through the small slot on the main frame member and provides for the simple attachment of a hook formed at the end of a flexible frame member to form a secure and practical hook joint.
