    Abstract: A portable impact-resistant athletic numerical indicator display produces highly visible numerals for observation by athletic participants and spectators. The display is provided with a series of shiftable component numeral panels which are connected to a selector lever by a coupling device including a stationary, slotted bar and yoke. The desired numeral to be displayed is presented behind a transparent face in the body by shifting the corresponding selector lever from a first position to a second position to compose the numeral to be displayed from the component panels. The display is conventionally used in contact sports such as football and is constructed to withstand impact with a player or the ground. The display is preferably mounted on a pole and is provided with a layer of padding to protect the playes from injury.
