Document Type and Number:
Japanese Patent JP2608280
Kind Code:
B2
Abstract:
A track system for toy vehicles contains straight and curved track pieces at the end of which are reference points that coincide with symmetry points of a track grid having a track module, M, which is a multiple of a building module, m, of a base plate for mounting the track pieces. The length of the straight track pieces which are disposed either parallel to or diagonally with respect to the track grid are a multiple of or 2ROOT 2 times a multiple of the track module, M. The curved track pieces are composed of a longer arcuate segment and a shorter straight segment. The center of the arcuate segment is deplaced with respect to the center of an arc, whose center is a symmetry point of the track grid and whose two radii define an angular range of the curved track piece. The center of the arcuate segment is defined by the intersection of an angle bisector of the tangents (T) of the reference points on the ends of the curved track piece and one of the two radii.
