Abstract:
PCT No. PCT/DK91/00374 Sec. 371 Date Jun. 4, 1993 Sec. 102(e) Date Jun. 4, 1993 PCT Filed Dec. 3, 1991 PCT Pub. No. WO92/10261 PCT Pub. Date Jun. 25, 1992.A cardan joint is provided for transmitting rotation between first and second parts of a toy building set. A first rotating part consists of a shaft having a coupler head at one end in the form of flaps which project radially outwardly with respect to the shaft axis and which form spherical segments of a cardan ball. A second rotating part includes a cavity into which the coupling head of the first part fits. Carrier pins extend radially inwardly into the cavity to mesh between and be displaced along the flaps so that the coupler head with the flap may be tiltable about at least one pin.
