摘要
The three-dimensional folding object, e.g. a dice cube, can be folded down into a two-dimensional object. It may have a power store, by which it automatically unfolds, or may be able to be restored to three-dimensional form by pulling accord, and/or manually. Traction force (5) may be applied at specific points (7) in the side surfaces (1, 3, 3a) or on the edges of the object.
