发明名称 Ice skate
摘要 An ice skate having a metal blade with the upper edge thereof embedded in the lower portion of the body of the skate which is made of plastic material. Plastic material integral with the body of the skate extends through longitudinally directed through-holes in the upper edge of the blade. There are at least three through-holes, including a centrally disposed centering through-hole which is entirely filled with plastic material integral with the material of the skate body. The other through-holes, located respectively forwardly and rearwardly of the centering through-holes, are only partially filled with plastic material integral with the body of the skate, the ends of the other through-holes which lie nearer the central through-hole being empty whereby to allow longitudinal shifting of the molded plastic body of the skate as it cools and hardens after having been injection-molded about the upper edge of the skate blade. The minimum dimensions of the spaces within said forward and rear through-holes are determined by the shrinkage of the plastic material, and by the distance of said additional through-holes from the centrally located, centering through-hole.
