Patent ID: 8262431

Claim:
A traveling toy system comprising: a lower track member; an upper track member disposed above the lower track member with an interval therebetween and having a bottom surface facing the lower track member and a top surface facing the bottom surface in the thickness direction thereof; a self-driven towing vehicle provided with a driving source and running by itself on the lower track member; and a towed object connected magnetically or mechanically to the self-driven towing vehicle and towed by the self-driven towing vehicle to run on the top surface of the upper track member, the upper track member made of a light permeable material and including light permeable regions arranged continuously or at intervals along a running direction of the towed object; the self-driven towing vehicle including a light emitting means for emitting light recognizable through the light permeable regions as viewed from the top surface of the upper track member; the light permeable regions each formed of a through-hole passing through the upper track member in the thickness direction; and the light emitting means emitting flashing light, driven by a driving circuit that causes the light emitting means to emit light while the self-driven towing vehicle and the towed object are disconnected, and mounted on the self-driven towing vehicle at a position that allows for visual confirmation that the light emitting means does not emit light while the self-driven towing vehicle and the towed object are connected.
