ABSTRACT:
A constructional toy having a plurality of nodal elements and a plurality of co-operating rod elements with each nodal element being substantially spherical and having a plurality of channels formed on its peripheral surface, including a first channel encircling said nodal element so as to pass through the poles thereof. At least four other channels are spaced about the peripheral surface so as to be intercepted by said first channel adjacent the poles of the nodal element, the lips of each said channel having inwardly projecting beads thereon. The rod element has a shank with a connecting portion at each end with a cross-section of a shape which can be "push-fitted" into a co-operating channel and held so that the longitudinal axis of the rod element is in substantial alignment with the geometrical center of the nodal element.
