Disclosed herein is a large umbrella configured to solve several existing deficiencies. The umbrella is configured for ease of operation, requiring very little effort for operation. This is achieved, in part, by use of a specially designed actuator arm used in conjunction with at least one pulley and counterbalanced weight system. Moreover, the umbrella canopy and framework is configured to allow the entire canopy to be lowered while remaining fully extended, so as to form a cover for a table into which its center pole is situated. Additionally, the umbrella canopy can be constructed with an extendible skirt. When unfurled, the skirt can extend the canopy cover so as to form an enclosure that fully surrounds the table, table legs, and chairs, for example.

An umbrella hub is provided that comprises an inner portion, an outer periphery, a lower portion and an upper portion. A plurality of vertical grooves is disposed in the outer periphery and is configured to receive umbrella ribs or struts. A plurality of grooves extends transverse to the vertical grooves. A retention member is disposed in each of the transverse grooves. A first configuration of the hub permits deflection of the retention member such that a transverse pin coupled with the umbrella ribs or struts can be inserted into the transverse groove in which the retention member is disposed. A second configuration of the hub prevents deflection of the retention member such that inadvertent withdrawal of the pin from the transverse groove in which the retention member is disposed is prevented.
