Abstract

An elongate platform comprising a length of paper tubing of arcuate cross section fitted into two longitudinal channels along the edges of a board. The platform is long enough to support two players, thereon without touching each other and is about nine inches wide. The height of the platform is substantially no greater than the radius of curvature of the arcuate tubing and may be considerably less than that radius. Cleats on the underside of board at each player station facilitate lifting the device. In an alternate embodiment the device is a solid body molded from a self skimming rigid urethane foam.

Claims

1. An adversary game device comprising an elongated platform that is unstable relative to its long axis and includes a substantially flat upper surface and an arcuate undersurface extending substantially from end-to-end of the device and of a radius such that its junction with the upper surface is substantially at the margins thereof, the length of the upper surface of said platform being such as to enable two contestants to stand thereon one at each end without physically contacting each other and attempt to dislodge each other by platformunbalancing movements, the width being not substantially greater than nine inches and the height of said upper platform surface being substantially no greater than the radius of said arcuate portion.

2. The game device of claim 1 which comprises a lower arcuate supporting shell that is a lengthwise section of relatively heavy paper tubing providing the undersurface of the platform and a flat upper platform surfaced, boardlike member providing the upper platform surface and having longitudinal channels adjacenT its margins, the edges of said shell being entrant of the channels and received and secured therein.

3. The game device of claim 2 in which there are manually engageable supporting cleats secured to the undersurface of the board-like member, one cleat underlying the station of each contestant.

4. The game device of claim 1 in which the height of the device is approximately the radius of said arcuate surface.

5. The game device of claim 1 in which the height of the device is less than the radius of said arcuate surface.
