Abstract
A fixture for supporting a pole in a gymnasium floor comprises a frame on which a pair of hinged lid members are supported. The hinged lid members are each formed with a flat rectangular piece and a piece comprising a semicircular recess and are slidable along tracks so that while the upper surface of the semicircular recessed pieces are flush with the floor the rectangular pieces hang vertically beneath the floor and while the rectangular pieces are flush with the floor the semicircular recessed pieces hang vertically beneath the floor. The semicircular pieces cooperate to define an opening through which the pole can be received and the rectangular pieces cooperative to cover the opening. With this arrangement, no part of the fitting protrudes from the floor so as to pose a hazard.
