Abstract:

A noise-making device which is particularly adapted to be utilized in conjunction with a skateboard or similar wheeled vehicle. The device comprises a ring-shaped component having one or two cylindrical projections extending from the outer peripheral edge thereof in a direction parallel to the axis of the ring. The other side of the ring is fastened to the end wall of a rotatable wheel, such as a skateboard wheel. The other component of the device comprises a somewhat rectangular, flat piece of metal having a pair of rounded edges and a hole in the center. This component is fastened to the wheel support device so that an edge of the metal piece is adjacent the end surface of the wheel. As the wheel rotates, the projections from the rotating component intercept the stationary plate to flex same, thereby creating sound.
