WIND INVERTIBLE UMBRELLA RIB LINKAGE SYSTEM

摘要

WIND INVERTIBLE UMBRELLA RIB LINKAGE SYSTEM A wind invertible umbrella with a topless rib linkage system. The rib linkage includes a flexor that is flexible in response to a wind gust directed against the underside of the umbrella's cover which is of sufficient force to invert the rib linkage into a nonuseful or inside out position without causing sufficient rib linkage damage to prevent reversing of the linkage back into a pre-wind gust position. The flexor also is flexible in response to a manual force applied to the rib linkage in a direction opposite to the wind gust force that is of sufficient magnitude to reverse the rib linkage from its non-useful position back into a useful umbrella position without causing sufficient damage to the linkage to prevent further opening and closing, i.e., further use, of the umbrella. Preferably the flexor is connected to the umbrella's runner, and the manual reversing force is applied to the runner for moving the runner down the centerpost toward the umbrella closed position when reversing the inverted rib linkage back into its pre-wind gust position.
