Abstract
A toy building set comprising a number of transmission elements in the form of a plurality of shafts and a plurality of toothed wheels, and a number of supporting elements for embedding of said transmission elements; and wherein the shafts have shaft extremities that are provided with splines in the form of a number of grooves spaced equally apart for mounting of one or more toothed wheels; and said toothed wheels having a central opening for receiving the spline of the shaft; and wherein the central opening on the toothed wheels is configured with one or more protruding flanges that engage with one or more of the grooves on the spline of the shaft with a view to ensuring that a toothed wheel mounted on a shaft is unable to rotate relative to the shaft; and wherein the toothed wheels are provided with a number of teeth that corresponds to or is equal to an entire multiple of the number of grooves on the spline of the shaft which makes it very easy to correctly mount the toothed wheels on the associated shafts.
