PCT No. PCT/EP91/01605 Sec. 371 Date Feb. 22, 1993 Sec. 102(e) Date Feb. 22, 1993 PCT Filed Aug. 24, 1991 PCT Pub. No. WO92/03195 PCT Pub. Date Mar. 5, 1992.A three-dimensional puzzle, which consists of several mutually connected puzzle elements which result in a regular tetrahedron in the assembled state. A number of identical tetrahedron-shaped puzzle elements and a number of mutually identical puzzle elements of different sizes are provided which all have the shape of a closed spatial frame. In this case, the development is such that the inner sides of the legs of the frame-shaped elements are identical to the outer sides of the frame legs of each of the next-smaller elements or to the surfaces of the smallest tetrahedron-shaped elements. All elements are in each case connected with one another along one of their edges, specifically such that they can be folded and can be pulled apart a distance at least on one end. In this case, the elements are arranged such that they form a number of chains which have different lengths, are each placed against one another with their largest element and consist of puzzle elements which all have different sizes. |
