Abstract
Abstract A rectangular umbrella has its supporting pole positioned at the middle of the back edge so as not to obstruct the space under the umbrella. A vertical sheet of fabric hangs from the back edge and portions of the side edges of the umbrella. This partial enclosure is completed by a removable front panel having a transparent upper portion and attachment means for connection with the umbrella and forward side edges of said vertical back fabric. The umbrella pole may be mounted on a stadium bench for sports spectators, on a boat seat for fishermen or duck hunters, or thrust into the ground for bird and big game hunters.
