A skate board has a platform, at least one supporting frame integrally formed on a bottom surface of the platform and extending parallel to a longitudinal direction of the platform, and a plurality of wheel trucks fixed with the supporting frame. At least one plurality of assembly holes is defined in the supporting frame and a center of each hole follows a curved bottom end face of the supporting frame. Each one of the wheel trucks includes a wheel axle disposed substantially perpendicular to the longitudinal direction of the platform and extending through one of the plurality of assembly holes. At least two wheels are rotatably mounted on each wheel axle, whereby the skate board is intended to support a user operating in a pitching way to advance the skate board on the ground, so as to simulate sea surfing on the dry land.

1. A pitching skate board apparatus comprising:a platform having front and rear end portions and an intermediate portion extending longitudinally therebetween, said platform being configured for supporting both feet of a user in a longitudinally spaced manner; at least one protrusive supporting frame protruding downward from a bottom surface of said intermediate portion of said platform and extending longitudinally between said front and rear end portions of said platform, said supporting frame having a bottom end face portion describing a continuous arcuate bulbous profile along an entire length thereof, said supporting frame having formed therein a plurality of first assembly holes arranged in equidistant manner relative to said bottom end face portion; and, a plurality of wheel trucks coupled to said supporting frame, each said wheel truck including at least one wheel axle engaging at least one said first assembly hole, and at least a pair of wheels coaxially disposed on said wheel axle, said wheel trucks being disposed sequentially along said arcuate bulbous profile; whereby said platform is displaceable in a rocking manner about a reference defined by said arcuate bulbous profile responsive to user actuation thereof.
