"COUPLING MECHANISM OF THE EXTREMES OF UMBRELLA RODS" characterized in that the organ that collects or stores the ends of the rods is the handle of the umbrella, which has a flared housing where the ends of the rods can be received and is slidable longitudinally with respect to the stick at a pre-established distance, which provides said bell-shaped housing inasmuch as it suffices to leave the ends of the rods free, allowing the opening of the umbrella and, the final positions of said sliding are determined by firing stops.
