ABSTRACT:
This toy track is adjustable in its vertical contour, and holds itself in the vertical contour to which it is adjusted. The track is made up of numerous short sections. Each track section carries connectors that fixedly but releasably lock that section to an adjacent section, at a vertical angle selectable arbitrarily by the user of the toy.
The connectors have mating pin-and-slot combinations for coupling adjacent track sections so that adjacent sections can rotate vertically with respect to one another. In addition the connectors have mating protuberance-and-groove combinations for locking the adjacent sections in particular vertical-rotation positions--that is, at the arbitrarily user-selectable angles.
The connectors are secured at opposite sides (laterally, relative to vehicle motion along the track) of each track section, and the connectors extend longitudinally beyond that track section to engage like connectors of the adjacent section. The connectors are upstanding from the roadbed sections and form sides for the adjustable track. Ninety degree turns and turnaround gates for use with the adjustable track are also provided.
