In many areas of the world, large umbrellas are used in conjunction with tables for the purpose of providing shade to those dining or drinking at the table. These table umbrellas usually include several legs that support the table a desired distance above the earth and in proximity to the chair surrounding the table. A large pole extends from the legs upwardly above the table so as to support an umbrella thereabove. In certain circumstances, the umbrella can be fixed or foldable. The umbrella effectively provides shade to those dining at the table so as to enhance the comfort of such persons at the table.
It is often the common problem in warm areas that the umbrella does not provide a sufficient cooling effect to those persons at the table. Although shade is important in enhancing one's comfort while dining and/or drinking, elevated ambient temperatures can also create a discomfort. Additionally, if there is no breeze, insects can often provide discomfort to persons at the table. Many existing table umbrella apparatus ineffectively provide a full range of services and environmental effects to those at the table.
Various items have been employed in the past with outdoor patio activities. In particular, electric fans have been used as a source of air for those sitting outside. Electric fans commonly use an electric motor with fan blades attached to the shaft of the rotor of the motor such that the electric motor is positioned central to the fan blades. Unfortunately, when the electric fan is used outside, it does not provide a great deal of protection from the sun nor a full range of comfort to those sitting at tables.
In the past, various patents have issued relating to fan assemblies and environmental control apparatus associated with table umbrellas. For example, U.S. Patent Publication No. 2002/0096203, published on Jul. 25, 2002 to Cohen et al., describes a fan assembly for a table umbrella. A motor assembly is connected to the pole that supports the table umbrella. A rather complicated arrangement of drive rings allows the umbrella to rotate relative to the table by the action of the motor.
U.S. Patent Publication No. 2002/0121296, published on Sep. 5, 2002 to R. B. Copple, describes an integrated electric fan and patio umbrella. The device uses an electric fan mounted as integral part of a patio umbrella. The umbrella fabric is open at the top so as to expose the fan to direct air from above. The umbrella can be raised and lowered around the fan blades without the need to hinge the blades up or down.
U.S. Patent Publication No. 2003/0168091, published on Sep. 11, 2003 also to Cohen et al., describes another type of fan assembly for a table umbrella. The fans are located on the underside of the table umbrella. The fans are driven by a shaft which extends through the table umbrella. As a result, the fans provide an airflow downwardly onto patrons sitting at the table below the umbrella.
