发明名称 Root ball display device
摘要 A root ball display device comprises a ball-supporting frame and a ball-positioning frame, which frames are joined at elevated junctions. The ball-supporting frame comprises at least three radially extending support members, each of which comprise a proximal support end and a distal support end. The distal support ends extend upwardly from the proximal support ends. The ball-positioning frame comprises at least three positioning members, each of which comprises an upwardly-extending vertex portion and laterally or peripherally adjacent periphery-forming end portions. The periphery-forming end portions are selectively joined to one another to form a common positioning periphery and the distal support ends are joined at the vertex portions for forming at least three ball positioning junctions. The ball-positioning junctions cooperate to position a root ball or similar other spherical body upon a display surface.
