Abstract
An ice skate of the "plastic" type is produced by separately molding two halves of the upper portion of the skate, by subsequently introducing between the two halves a steel runner and by welding the two halves together to form a unitary plastic upper portion of the skate. The advance over prior art of "plastic" skates is in avoiding internal stress of the plastic section of the skate due to internal stress developed in known "plastic" skates due to the shrinkage of the plastic material. The molds for producing the two halves are considerably less expensive than those required in the production of known, single-piece plastic skates. One of the "halves" of the plastic upper portion comprises at least one generally complete supporting column section provided with a flange for securing the skate to a skating boot.
Claims5
An ice skate of the type having a plastic, generally unitary upper portion including a base section and two flange portions for securing the skate to a boot, and a metallic runner embedded in a lower section of said upper portion with a lower section of said runner protruding downwardly along said base section wherein said plastic, generally unitary upper portion comprises two uneven halves, said runner being located between the base sections of said two halves, said two halves being fixedly secured to each other along a joint extending generally longitudinally with respect to said runner, wherein one of said halves is an integral part including at least one complete flange portion and a substantial portion of a supporting column section associated with said at least one complete flange portion.
