摘要 An apparatus for playing a racquet and ball game in a confined space. The apparatus comprises a foldable or demountable frame (2) supporting walls (3) and a roof (4) of woven plastics mesh. The structure (1) is supported on a playing surface divided into opposed playing zones (17, 18) by a pair of spaced parallel nets (12, 12). The upper portions (10a) of the end walls (10) are inclined inwardly at 45 DEG relative to respective upright end walls (10). The support surface, the wall surface and the roof surface all form playing surfaces for the game and the space between the nets (12, 12) is a dead ball space.
