  • Patent number: 5826835
    Abstract: A toy vehicle switch track comprising a junction element having an incoming track and a plurality of outgoing tracks, a pivotable switching mechanism, an activator bar, and a guide slot. The pivotable switching mechanism is positioned at an intersection between the incoming track and the outgoing track, and guides a toy vehicle from the incoming track to one of the outgoing tracks. The activator bar has first and second ends and passes through the junction element from a first junction element edge to a second junction element edge. The activator bar engages a portion of the pivotable switching mechanism wherein the activator bar is used to alternately position the pivotable switching mechanism between the plurality of outgoing tracks. The first end and the second end each comprise a handle. The opposing handles provide an alternating resistive force against the first junction element edge and the second junction element edge to prevent over-travel of the pivotable switching element.

  • Patent number: 5454513
    Abstract: A toy track section comprises a body having an upper face, a pair of spaced, parallel rail members formed in the upper face, and a plurality of spaced discontinuities formed in at least one of the rail members, and preferably both. The rails and discontinuities are of a size and shape to permit wheels of a toy train to roll and be guided by the rail members while causing a repeating "clacking" sound to be emitted by the wheels rolling on the rail members, in a manner reminiscent of a full-sized, moving train.
