Abstract
Abstract A trackway for toy vehicles which includes a plurality of elongated track sections placeable end-to-end and having upper surfaces defining a roadbed for the toy vehicles along the top of the trackway. The track sections have complementary engageable latch-release components on the ends thereof for connecting the track sections end-to-end and holding the track sections against separation, automatically in response to longitudinal pushing type abutment of the track sections against each other. In the disclosed embodiment, the latch-release mechanism includes a flexible portion formed integrally with each track section.

Claim 1
Independent Claim
209 words
A trackway for toy vehicles including a plurality of elongated track sections, each section having two end faces, an upper surface defining a roadbed for said toy vehicles along the top of said trackway, and complementary engageable connection means for releasably maintaining the track sections in abutment with one another, said connection means comprising: a generally vertical, flexible, longitudinally extending tab protruding from the end face of said track section and positioned on one side of said track section, said tab including a depression on one side thereof and outwardly of said end face; detent means on the opposite side of said track section inwardly of said end face for engaging and flexing the flexible tab outwardly and seating within said depression of an adjacent track section automatically in response to longitudinal movement of said track section and abutment of said end faces to secure the track sections against inadvertent longitudinal separation; a recess formed in the end face of the track section adjacent one side thereof; and a complementary longitudinally extending tab protruding from the end face of said track section for insertion into the recess of an adjacent track section to prevent the adjacent track sections from being canted relative to one another about a transverse axis.
