Patent number: 6082383Abstract: An operating mechanism for "patio type" umbrellas uses an actuator sleeve in order to open and close the canopy. The sleeve is in connection an inner rod on the inside of the main shaft that in turn is used to open and close the ribs that support the canopy of the umbrella. Movement of the actuator sleeve upward will move the inner rod upward as well as pull the ribs downward so as to close the canopy. Movement of the actuator sleeve downward will pull the ribs away from the central shaft and hence open the canopy. Because of the short length of the ribs combined with the weight of the canopy itself, it is believed that this makes such large patio type umbrellas easier to open and close using this sleeve actuator mechanism.Type: GrantFiled: July 28, 1998Date of Patent: July 4, 2000Inventor: Robert Joe Wilson
