Benefits of technology

"The present invention is an umbrella device that has a canopy that can block sun and rain while also producing air flow when rotated. The canopy is made up of triangular shaped blades that are attached to a hub and extend radially from the hub. The blades have a support rod that provides support and creates space between them to allow airflow. The airflow creates a cooling breeze and helps to remove hot air from underneath the canopy. The invention also has a reversible motor that can be used to create a hot air flow from underneath the canopy."

Problems solved by technology

When modified to encompass weight-reducing designs these devices are prone to buckling when strained by wind.
The controlled folding up of the cover material and of the rod produces strain that has been shown to be technically difficult with umbrella devices of large surface areas, and poses the danger of damage to the thin cover material of low flexural strength in the contact points between the cover and the ribs.

Embodiment Construction

[0020]Reference may be made throughout this specification to “one embodiment,”“an embodiment,”“embodiments,”“an aspect,” or “aspects” meaning that a particular described feature, structure, or characteristic may be included in at least one embodiment of the present invention. Thus, usage of such phrases may refer to more than just one embodiment or aspect. In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments or aspects. Furthermore, reference to a single item may mean a single item or a plurality of items, just as reference to a plurality of items may mean a single item. Moreover, use of the term “and” when incorporated into a list is intended to imply that all the elements of the list, a single item of the list, or any combination of items in the list has been contemplated.

[0021]Referring now to FIG. 1, the present invention comprises an umbrella device 102 comprised of a base 108, a tripod support ass...

Abstract

A motorized umbrella fan whereby a motor drives the rotation of an umbrella assembly, which is comprised of an umbrella skeleton and a canopy, stretched over the skeleton. The canopy functions as a sunshade and plurality of fan blades each of triangular shape radially extending from a hub. A leading edge of each of the plurality of blades has a unshaped portion that is attached to a trailing edge of a preceding blade in a manner that creates vertical spacing between the leading edge and trailing edge of adjacent blades. This creates a slope within each fan blade and a channel between adjacent blades through which air flows. The air flow pushes stale hot air from underneath the canopy, providing a cooling breeze.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Application No. 61 / 035,259 titled “Motorized Umbrella Fan” filed on Mar. 10, 2008 having attorney docket number 60315.0005USP1 and U.S. Provisional Application No. 60 / 978,574 titled “Motorized Umbrella Fan” filed on Oct. 9, 2007, having attorney docket number 60315.0002USP1, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The instant invention relates to umbrellas and outdoor canopies in combination with fans. Particularly, the present invention relates to outdoor umbrellas and outdoor canopies that also function as fans to provide a cooling air flow to individuals sitting setting beneath the umbrella while also providing relief from the sun and rain. More particularly, the present invention relates to an umbrella that has a canopy consisting of cloth blades that are rotated about a shaft producing a cooling air flow. More particularly, the presen...
