BRIEF DESCRIPTION OF A PRESENTLY PREFERRED AND VARIOUS ALTERNATIVE EMBODIMENTS OF THE INVENTION
Prior to proceeding to the more detailed description of the present invention it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.
Reference is now made, more particularly, to FIGS. 1-3.
A foldable portable stadium chair, generally designated 10, is provided. Such foldable portable stadium chair 10 folds between a collapsed position for carrying and an open position for seating. Such foldable portable stadium chair 10 includes an adjustable base member 12 engageable with and securable to a bleacher bench 14, such adjustable base member 12 being manufactured from a first predetermined material and having a first predetermined size and a first predetermined shape. It is presently preferred that such adjustable base member 12 is releasably securable to bleacher benches measuring between about 10′′ to 14′′ inches in width. It is further presently preferred that such adjustable base member 12 includes at least one first locking mechanism 16 for use in securing such adjustable base member 12 to a bleacher bench 14. It is also presently preferred that such adjustable base member is telescoping.
A chair frame 18 is coupled to such adjustable base member 12 and has at least a portion thereof movable towards and away from such adjustable base member 12.
