ABSTRACT:
A coupling device for a hat-like umbrella frame consisting of a coupling member and a rib stretcher. A visor rib comprising an outer segment with a smaller diameter than the inner segment thereof is pivotably connected to a main rib and a respective rib stretcher. The coupling member is substantially U-shaped with an opening at one end thereof. The coupling member is disposed between the rib stretcher and the visor rib for allowing the visor rib to pass through. The outer segment of the visor rib is freely slidable within the opening of the coupling member. The inner segment of the visor rib is unable to pass through the opening member so that a sliding movement between the visor rib and the coupling member will be stopped. When opening the umbrella, the visor rib is movable outwardly and downwardly until the inner segment of the visor rib is stopped by the coupling member to become substantially horizontal and the main rib is stopped to further move outwardly and upwardly due to the connection between the visor rib and the main rib.
