A wheeled attachment system for efficiently attaching to a spine board to allow the spine board to be easily maneuvered over various surfaces (e.g. flat surfaces, stairs, etc.). The wheeled attachment system generally includes a front support, a pair of wheel assemblies extending from opposing sides of the front support, a pair of side supports extending from the front support adjacent the pair of wheel assemblies and at least one strap extending from the pair of side supports. The side supports and the front support define a cavity adapted to receive an end of a spine board, wherein the strap is adapted to secure the pair of wheel assemblies about the spine board. A pair of extension members interconnect the pair of wheel assemblies with the front support so that a center rotational axis of the pair of wheel assemblies is vertically offset with the front support.

I claim: 1. A wheeled attachment system, comprising: a front support; a pair of wheel assemblies extending from opposing sides of said front support; a pair of extension members interconnecting said pair of wheel assemblies with said front support so that a center rotational axis of said pair of wheel assemblies is vertically offset with said front support; a pair of side supports laterally extending from said front support; wherein said pair of side supports and said front support define a cavity adapted to securely receive an end of a spine board; and at least one strap extending from said pair of side supports, wherein said at least one strap is adapted to secure said pair of wheel assemblies about said spine board. 2. The wheeled attachment system of claim 1, wherein said pair of wheel assemblies extend inwardly from said pair of extension members. 3. The wheeled attachment system of claim 2, wherein said pair of wheel assemblies are positioned underneath said front support. 4. The wheeled attachment system of claim 1, wherein said pair of wheel assemblies extend outwardly from said pair of extension members. 5. The wheeled attachment system of claim 1, wherein said pair of extension members are comprised of a U-shaped cross-sectional configuration. 6. The wheeled attachment system of claim 1, including a footrest assembly extending from said front support. 7. The wheeled attachment system of claim 6, wherein said footrest assembly includes a retaining portion comprised of a sideways V-shaped configuration. 8. The wheeled attachment system of claim 7, wherein said footrest assembly includes a riser extending angularly upward from a lower part of said retaining portion. 9. The wheeled attachment system of claim 1, wherein said pair of extension members each include an upper connecting element to connect to said front support and a lower connecting element to connect to said pair of wheel assemblies. 10. The wheeled attachment system of claim 9, wherein said upper connecting element and said lower connecting element extend in a similar direction from a respective said extension member. 11. The wheeled attachment system of claim 9, wherein said upper connecting element and said lower connecting element extend in an opposite direction from a respective said extension member. 12. The wheeled attachment system of claim 1, wherein said pair of side supports are movably attached to said front support. 13. The wheeled attachment system of claim 1, including a footrest assembly extending from said front support, wherein said footrest assembly includes a handlebar. 14. The wheeled attachment system of claim 1, including a footrest assembly slidably connected to said front support. 15. The wheeled attachment system of claim 1, wherein said pair of wheel assemblies are comprised of tri-wheeled assemblies. 16. A wheeled attachment system, comprising: a front support; a footrest assembly extending from said front support; wherein said footrest assembly includes a handlebar; a pair of tri-wheeled assemblies extending from opposing ends of said front support; a pair of extension members interconnecting said pair of tri-wheeled assemblies with said front support so that a center rotational axis of said pair of tri-wheeled assemblies is vertically offset with said front support; a pair of side supports laterally extending from said front support; wherein said pair of side supports and said front support define a cavity adapted to securely receive an end of a spine board; and at least one strap extending from said pair of side supports, wherein said at least one strap is adapted to secure said pair of wheel assemblies about said spine board. 17. The wheeled attachment system of claim 16, wherein said pair of tri-wheeled assemblies extend inwardly from said pair of extension members. 18. The wheeled attachment system of claim 17, wherein said pair of tri-wheeled assemblies are positioned underneath said front support. 19. The wheeled attachment system of claim 16, wherein said pair of tri-wheeled assemblies extend outwardly from said pair of extension members. 20. A wheeled attachment system, comprising: a spine board; a front support; a footrest assembly extending from said front support; wherein said footrest assembly includes a handlebar; wherein said footrest assembly includes a retaining portion comprised of a sideways V-shaped configuration; wherein said footrest assembly includes a riser extending angularly upward from a lower part of said retaining portion; a pair of tri-wheeled assemblies extending from opposing sides of said front support; a pair of extension members interconnecting said pair of tri-wheeled assemblies with said front support so that a center rotational axis of said pair of tri-wheeled assemblies is vertically offset with said front support; a pair of side supports laterally extending from said front support; wherein said pair of side supports are movably attached to said front support; wherein said pair of side supports and said front support define a cavity adapted to securely receive an end of said spine board; and at least one strap extending from said pair of side supports, wherein said at least one strap is adapted to secure said pair of wheel assemblies about said spine board; wherein said pair of extension members each include an upper connecting element to connect to said front support and a lower connecting element to connect to said pair of wheel assemblies.
