发明名称 Portable folding game ramp
摘要 A play enhancing game ramp for use in a game wherein opposing players exchange an elastic projectile between each player over a barrier on a playing surface. the preferred ramp for tennis use is employed in sets of three adjacent ramps which each includes a portable base frame, a pair of connected planar ramp sections hinged together and movable between a folded configuration and an unfolded configuration in which the ramp sections form a single ramp lying in a path extending from the predetermined height toward the playing surface, and strut supports connected between the pair of ramp sections and the portable base frame for causing said pair of ramp sections to counterbalance one another. Each of the pair of ramp sections has a top surface which reflects the trajectory of an incident projectile so that it passes over the barrier. The ramp (in alternate embodiments) can also be employed to enhance the play of other games such as badminton and ping pong.
