ABSTRACT:
An umbrella suitable for mounting over a surface which allows selective venting of air trapped within the covered area is disclosed. The umbrella includes a vertical support structure (12) which comprises a rod (16) having a first end (20) and a further end (18). The further end (18) is conventionally mounted such that the longitudinal axis of the vertical support structure (12) extends substantially perpendicular to the covered surface. A canopy member (14) is carried by the first end of the vertical support structure and defines an opening (22) such that air currents flow through the opening (22) in an upwardly direction and heat may be readily dissipated from beneath the canopy (14). Also provided are mounting means (24) for holding the canopy member (14) at a preselected height while keeping the opening (22) as free from obstructions as is possible to allow fluid communication between the spaces above and below the canopy (14). A cover unit (44), which serves to prevent precipitation, particulate matter and the like from entering the covered area through the opening (22), is positioned at a preselected height above the opening (22). Also provided are means for adjustment (36) which support the cover unit (44) and allow adjustment of the vertical distance between the cover unit (44) and the canopy (14), thus permitting a controlled flow of air currents through the opening (22).
