PCT No. PCT/DK95/00388 Sec. 371 Date May 19, 1997 Sec. 102(e) Date May 19, 1997 PCT Filed Sep. 28, 1995 PCT Pub. No. WO96/09869 PCT Pub. Date Apr. 4, 1996A stacking block system includes a plurality of blocks, each having a top face and a plurality of side walls extending downwardly from the top face. At least one coupling knob extends upwardly from the top face and has a substantially spherical upper part and a substantially cylindrical lower part. A tubular coupler or flange extends downwardly from the top face and beyond the side walls is complementary to the coupling knob, enabling coupling of two blocks. The tubular flange guides the coupling knob to enable coupling of two blocks, even when the blocks are tilted with respect to each other. |
