发明名称 Ball rebound apparatus
摘要 A recreational ball rebound wall having a plurality of rigid, portable panels. The panels are supported in a vertical position by a pair of spaced apart support tracks. The panels are supported on the tracks by rollers whereby the panels are horizontally slidable in an abutting relationship. Alignment studs in the abutting edges of each of the panels and rods extending horizontally through the panels are provided for securing the panels in abutting relationship. Wedges are selectively inserted between at least one of the panels and the tracks to position the panels to form a flat, planar surface when the panels are in abutting relationship.
