Abstract
A construction toy including a base portion having a grid defined thereon by a plurality of substantially vertical grooves for use in combination with accessory articles. The grooves defined on the grid are arranged to intersect one another at right angles, each pair of which defines a track section over which a suitable vehicle may travel. A plurality of building wall panels are provided for use by positioning in the grooves of the grid to maintain the panels in a generally vertical position to permit combining of the panels to define structures such as houses, trees, or other structures. A plurality of track sections may be connected to the base to provide a path of travel to and away from the base. A connecting device is provided on the end of each track section for connection between adjacent track sections or to the base to secure the assembly as a unitary layout. Each track section is reversible and includes on one side a generally flat surface for traversing by vehicles such as cars and trucks. A pair of tracks are provided on the other side of the track sections for use with vehicles having flanged wheels. Spaced tabs are provided along the tracks to strike the wheel flanges and produce a clicking sound as the vehicle rolls along the track.
