Abstract (en)
An element (1-4) for composing a track of the fall type for run of marbles, which comprises a guide member (2) for the insertion of marbles, intended to be placed beneath the arrival of a preceding track element or at the upper start point of a track, an exit guide member (1) for the marbles, intended to be placed at a level lower than the level of the insertion guide member (2) and generally over the start end of a subsequent track element, and a track section (4) extending in the form of a pair of rails from said insertion guide member (2) to said exit guide member (1), by following at least in part a helicoidal trajectory: Preferably, the track section (4) which follows at least in part a helicoidal trajectory has at its beginning a rectilinear section (4") for approach to the helicoidal portion (4') of the track section (4). The entire track element (1-4) may be embodied in a single piece of plastics formed in plane configuration and it may be rendered three-dimensional by insertion of spacers (7). <IMAGE>
