发明名称 Electrical toy vehicle tracks
摘要 A track section for use with an electrically actuated toy vehicle and which can be joined end to end with other identical track sections to complete a vehicle track. The section includes at least one vehicle path and at least two electrically-conducting strips from which the vehicle obtains its electrical power. The strips extend from end to end of the section. The end of each strip is in a recess which tapers width-wise in a direction away from the end of the section. The recess is formed by an abutment wall adjacent to the end of the strip and a cam wall inclined to the longitudinal axis of the section. The cam wall is adapted to engage a corresponding cam wall on an adjacent section when the two sections are brought together so as to move the ends of the strips of the two sections into side-by-side engagement between respective abutment walls of the two sections. The section has a snap-fit retainer so that two sections can be releasably coupled together. The retainer includes a ledge having an open-end mouth for receiving a lug on an adjacent section. The lug enters and leaves the mouth along a path generally parallel to the cam surfaces.
