Abstract:
1. A skate blade assembly comprising: a skate blade member; a support for the skate blade member for attachment of the skate blade member to a skate boot; a resistance heating member extending along a surface of the skate blade member for applying heat to the skate blade member; a battery power source carried on the support for supplying current to the resistance heating member; the resistance heating member comprising an elongate electrically conductive straight wire of constant cross-section along which the current from the battery power source is conducted; the straight wire having a cylindrical layer of electrically insulating material surrounding an outside peripheral surface of the wire, the wire extending in a substantially straight path along the surface of the skate blade member and the wire being against the surface so that one side of the cylindrical layer is held in direct contact with the surface to transfer heat thereto; wherein the skate blade member includes a metal skate blade with an over-molding of plastics material applied on at least one side surface of the blade so as to form a raised band of the plastics material along the side surface of the blade with an outer surface of the plastics material spaced outwardly from the side surface of the blade, wherein the plastics material includes a groove extending from an open mouth of the groove at the outer surface of the plastics material to a base of the groove at the side surface of the blade and wherein the resistance heating member is received in the groove; wherein the over-molding of plastics material extends along both sides of the metal skate blade with the plastics material forming on each side of the metal skate blade a respective groove with a base of the groove at the side surface of the metal skate blade and wherein a portion of the resistance heating member is received in each groove; and wherein the wire is compressed into the groove by a deformable strip of a resilient material.
