Abstract: A playing surface suitable for handball, racquetball and similar games is presented by a composite panel having two structural and functional components comprising a base sandwich panel member for imparting strength and rigidity to the panel construction and a relatively thin, finish panel member having the requisite surface hardness. Each member is composed of prefabricated sections joined during assembly by spline and slot connections, the lines of joinder of the finish panel sections being substantially out of alignment with the joint lines of the base panel sections to increase the strength of the composite panel. The panel construction forms a self-supporting wall and thus may be employed exclusively in the construction of playing courts, or use in conjunction with conventional walls, ceilings and floors as desired.
