The task set is determined by the Protection claim 1 reproduced teaching solved.

With such a design of the two interacting coupling members, the one with its two remains against one another folded hook inserted through the elongated hole of the outer part Hook part after folding back the two hooks outwards both in relation to pivoting movements and in relation to one another other shifts relative to the eyelet part reliable anchored.

Refinements of the innovation relate to further advantageous details of the design of the hook ax.

In the drawing, the innovation is illustrated for example; show it:

^ ₁₁ · Λ

The two cubes shown in FIGS. 1 and 2, the farton blanks of which can be seen in the associated FIGS are, according to the embodiment, components a ring-shaped closed chain of dice consisting of eight connected cubes, which in a known manner become one different overall shape and in particular can be joined together to form two cube bodies with different outer surfaces are. During the cube 1 with three other subsequent (not shown) cubes via an adhesive flap 3 is connected, the cube 2 is connected there with a further three cubes (not shown) via an adhesive tab 4 firmly connected. So that all eight cubes after a certain folding which is not an object of the present novelty It has to be shipped in a space-saving manner Proven to be expedient, the two sets of four cubes each at both ends are detachable via a coupling connection to be connected to one another, as can be seen in particular from FIGS. The one described in more detail below Coupling connection is so simple that it can be easily assembled by anyone at the point of re-unfolding the cube can be.

The one coupling member forming an eyelet 5 is made from a simple cover flap which, in its central area, has an elongated hole 7 running parallel to its base edge 6 on v / eist. When the cube 1 is unfolded, the eyelet is located 5 at the bottom of the cube 1 next to another simple cover flap 8.

The associated coupling member of the square 2 consists of an additional tab S, the Jurch in your smock area recesses 10 engaging from both sides are two opposite one another outer hook 11 forms. At their one compared to the length L of the elongated hole 7 a somewhat smaller mutual 1 spaced roots runs transversely to each

It is also preferred if the outer linden trees of the essentially rectangular hooks 11 are rounded at their corners 14 located toward the circular edge.

SO The coupling together of the two coupling members formed by the sleeve part 5 and the additional tab 9 can be achieved when the loirfei 2 is completely unfolded and the?. _; Dice 1 done. All that is required is that the
