Toy car racetrack assembled from multiple paperboard blanks
First Claim
1. A kit for the construction of a toy racetrack for radio controlled cars, comprising:
- a) a plurality of first blanks having portions defining a curved roadway having an inner edge and an outer edge, and portions of each first blank defining radial slits which extend from the inner edge to the outer edge, the radial slits facilitating the bending of the first blank to form a curved, banked roadway section, the first blanks being joinable to form a continuous roadway for the travel of radio controlled toy cars thereon, wherein the first blanks are adapted to being erected on a support surface such that the roadway inner edge engages said support surface and the roadway outer edge is elevated above the support surface; and
b) a plurality of second blanks which are foldable to engage the outer edge of the first blanks and which are adapted to form a continuous barrier which extends above and is separate from the roadway for the retention of toy cars on the roadway, wherein each blank is formed of corrugated material having a first planar layer, a second planar layer, and an intermediate undulating layer attached between the first and second layers.

Abstract
Die-cut corrugated paperboard blanks define a closed looped oval race track. The blanks form a flat roadway surface which is supported on paperboard wedges at an angle to provide banked straightaways and curves for the travel thereon of radio controlled battery powered cars. A paperboard barrier formed of a plurality of folded corrugated blanks is engaged against the elevated edges of the roadway to prevent the escape of the cars from the race track. The blanks which form the banked curves of the roadway have a plurality of radial slit scores which facilitate the bending of the corrugated paperboard blanks to approximate a frustroconical shape.

3. A toy car racetrack assembly comprising:
-
a) at least one paperboard blank forming a closed looped roadway having an inner and an outer edge, the roadway defining a direction of travel, and forming a continuous path, the roadway having indicia aligned parallel to the direction of travel which delineate a plurality of lanes along the roadway, the roadway having curved portions, which are inclined from a horizontal plane, the inclined portions having elevated outer edges, wherein the inner edge of the inclined roadway engages a support surface and the outer edge is elevated above the support surface; b) at least one radio controlled toy car having bidirectional control and being battery powered and being remotely operable to drive on the roadway; and c) a barrier which extends vertically above the roadway and which is separate from the roadway, wherein the barrier prevents cars from leaving the roadway along the roadway outer edge. - View Dependent Claims (4)

5. A toy racetrack formed of paperboard for use with radio controlled toy cars comprising:
-
a) at least one paperboard blank folded to form a roadway surface adapted for use with controlled toy cars, wherein portions of the roadway surface are inclined to form a banked roadway having an inner edge and an outer edge, and wherein the banked portions have an inner edge which engages a support surface and an elevated roadway outer edge; and b) at least one paperboard barrier blank separate from and adjacent to the elevated roadway edge, the engaged blank extending above the roadway surface to form a barrier to prevent remotely operated toy cars from leaving the roadway surface over the elevated roadway edge. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
