An ice skateboard comprising an elongated platform having secured to the front and rear portions of the underside conventional skateboard trucks, with transverse axles supported by a structure facilitating slight controllable swinging movement of the axle in response to the shifting of weight on the platform, wherein each of the front and rear axles rotatably supports at opposed ends thereof elongated skate blade mounting units in a manner to be parallel to the center line of the platform, and each of the mounting units bearing a skate blade protruding in a direction away from the platform, the exposed edge of each blade having a front to rear contour of slightly convex curvature and a transverse contour of markedly concave curvature providing closely spaced ice gripping edges, and the mounting units for said blades being so fashioned as to provide a cant to the blades of at least 5°, thereby convergently orientating the mounted blades. The cant can be either fixed or variable, with variations being provided by an insert in the mounting unit facilitating its rotation on a front to rear axis, and an adjustable linkage connecting an upwardly protruding member on the mounting unit with a portion of the truck structure. When such adjustable linkage is aligned with the truck axis adjusted cant remains constant during use, whereas if such linkage is disposed angularly with respect to the truck axis the preset cant will be varied by the shifting of weight on the platform.

In an ice skateboard comprising an elongated platform having secured to front and rear portions of an underside skateboard trucks, with transverse axles supported by a structure facilitating slight controllable swinging movement of the axle in response to the shifting of weight on the platform, wherein each of the front and rear axles rotatably supports at opposed ends thereof elongated skate blade mounting units in a manner to be parallel to the center line of the platform, and each of the mounting units bearing a skate blade protruding in a direction away from the platform, the exposed edge of each blade having a front to rear contour of slightly convex curvature and a transverse contour of markedly concave curvature providing closely spaced ice gripping edges, the improvement that comprises incorporating in the blade mounting units structural features imparting to the blades a cant of at least 5°to thereby convergently orient the exposed edges of the mounted blades, wherein the structural features of said blade mounting units provide for rotation of said mounting units, both with respect to the truck axles, and with respect to the longitudinal dimensions of said mounting units, and upwardly protruding elements at the top of said mounting units in alignment of the truck axles are joined by adjustable linkages to spaced portions of said trucks, and longitudinal adjustment of said linkages providing controlled rotation of said mounting units with respect to their longitudinal dimensions to thereby controllably vary the cant angles of said blades.
