Abstract
Abstract A game or sport facility in the form of an enclosed court which, because of its shape and arrangement, permits the playing by two persons of a vigorous and strenuous competitive racket and ball game or sport (adapted to the facility) within an area considerably smaller than has heretofore been possible. The enclosure for the court includes upstanding walls on all sides thereof wherein one wall, which is designated as the front wall of the facility, is adjoined by four obtusely angled, narrow, upstanding wall sections with two of the sections on each side thereof. These sections preclude rebounds of balls off of the aforementioned front wall which would be too difficult for a competitor to return against the wall in the limited playing area of the game facility.
