<p>A track in the form of a running track for model electric cars, comprised segments in which there is provided at each end, in a substantially central position, at least one flat tongue (9) divided axially into two parts, in order to form two toothed members (9a, 9b) projecting lengthwise from such ends and capable of adapting flexibly in a transverse sense, and a prismatic cavity (8) with a lateral profile matching that of such tongue (9), there being furthermore provided a flat tongue (11) having a cam or step (11b) and a cavity of matching profile (12a) located within a box-shaped body (12) forming a line of contact between each pair of segments in the form of a broken line diagonally inclined in such a way as to improve the rigidity of the joint and prevent deformation in the vertical sense of the said segments relative to such line of contact. <IMAGE></p> |
