Abstract
Abstract Vertical and horizontal bars are joined to make upstanding substantially square grids arranged to form a cruciform structure with open ends, facing pairs of grids of the structure being the same distance apart. Spanning members longer than the distance between facing grids are provided to extend through facing rectangular openings of the grids, the spanning members having transverse cleats near their ends securing the spanning members in position. The spanning members may be placed in a wide variety of positions to provide varied play possibilities. Fabric sheets with peripheral ties are provided to selectively close off or cover portions of the structure.
