Patent ID: 8398100

Claim:
A skateboard apparatus, comprising: a truck assembly positioned between a first truck member and a second truck member for supporting a board structure, wherein said truck assembly comprises: a suspension assembly positioned through said board structure, wherein said suspension assembly comprises a suspension spring disposed within a housing that bulges above an upper surface of said board structure, for creating a rocking motion along a length of said board structure; a pivot element pivotally connected to said suspension assembly for enabling said suspension spring of said suspension assembly to create said rocking motion along said length of said board structure about a longitudinal axis of said board structure; a collapsible tubular member threadedly connected to said pivot element, wherein said collapsible tubular member is mounted on a third truck member; a compression spring externally and coaxially mounted around said collapsible tubular member, wherein said compression spring alternately expands and compresses for extending and retracting said collapsible tubular member; and a tension spring coaxially extending through said collapsible tubular member, wherein said tension spring, in communication with said compression spring, telescopically extends and retracts said collapsible tubular member for creating an upward motion and a downward motion respectively, of said board structure; whereby said skateboard apparatus propels forward via said first truck member, said second truck member, and said third truck member on receiving weight of a user standing on said upper surface of said board structure, and creates a surf-like motion on a ground surface by synchronization of said upward motion and said downward motion of said board structure with said rocking motion of said board structure performed by said suspension assembly.
