Claim 7

A portable toy train track comprising a plurality of interlocking portable track sections each of said portable track sections being of unitary molded lightweight frame construction, said frame being shaped to form a pair of parallel spaced longitudinal wheel bearing rails of channel cross sections and crossties spaced at longitudinal intervals to interconnect the rails for parallel spacing thereof, and vertical support of said rails, with end located crossties being of channel cross section, with ends of said track section being provided with integrally molded flanges extending longitudinally of the track section and provided with laterally extending segments, said flanges extending longitudinally for a distance sufficient to seat partially in rail channels with the lateral segments seated adjacent lateral channel walls in end located crossties of adjoining track sections to interlock adjoining track sections and bring their wheel bearing rail ends into proximity alignment to form the toy train track, and with ends of said rail sections provided with alignment lips and recesses shaped to receive said lips, said lips and recesses being located to prevent casual release of assembled molded track section.

Claim 8

The portable toy train track as claimed in claim 4 wherein said flanges are located below ends of wheel bearing rails and extend downwardly to provide continuous ground support below rail joints between adjoining track sections.

Claim 9

The portable toy train track as claimed in claim 5 wherein said Rails are channel shaped with open ends sized to receive the lips with sufficient capture to prevent casual release of assembled track sections.

Claim 10

The portable toy train track as claimed in claim 6 wherein the flanges in the track sections are of channel cross section having channels in alignment with the rail channels.

Claim 11

The portable toy train track as claimed in claim 4 wherein said track sections are provided with supporting edges interconnecting crossties and extending laterally from rail channels to enhance track section vertical support and structural rigidity.

Claim 12

A portable toy train track comprising a plurality of interlocking portable track sections each of said portable track sections being of unitary molded lightweight frame construction, said frame being shaped to form a pair of parallel spaced longitudinal wheel bearing channel-shaped rails with open ends and crossties spaced at longitudinal intervals to interconnect the rails for parallel spacing thereof, and vertical support of said rails, with end located crossties being of channel cross section, with ends of said track sections being provided with integrally molded T-shaped flanges of channel cross section with the crossbar on each T-shaped flange forming a laterally extending segment, said flanges extending longitudinally for a distance sufficient to seat the crossbars adjacent lateral channel walls in end located crossties of adjoining track sections and bring their wheel bearing rail ends into proximity alignment to form the toy train track, with the wall being chamfered upwardly and away from the bottom of the adjacent crosstie wall, and with selected ends of said rails being provided with alignment lips and with the open ends of the rails shaped to form recesses to receive said lips, said lips and recesses being located to prevent casual release of assembled molded track sections.

Claim 13

A portable toy train track comprising a plurality of interlocking portable track sections each of said portable track sections being of unitary molded lightweight frame construction, said frame being shaped to form a pair of parallel spaced longitudinal wheel bearing channel-shaped rails with open ends and crossties spaced at longitudinal intervals to interconnect the rails for parallel spacing thereof, and vertical support of said rails, with end located crossties being of channel cross section, with ends of said track sections being provided with integrally molded T-shaped flanges of channel cross section with the crossbar on each T-shaped flange forming a laterally extending segment, said flanges extending longitudinally for a distance sufficient to seat the crossbars adjacent lateral channel walls in end located crossties of adjoining track sections and bring their wheel bearing rail ends into proximity alignment to form the toy train track, with the wall being chamfered upwardly and away from the bottom of the adjacent crosstie wall, and with selected ends of said rails being provided with alignment lips and with the open ends of the rails shaped to form recesses to receive said lips, said lips and recesses being located to prevent casual release of assembled molded track sections.
