Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
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.
Claim 2
Dependent Claim
131 words
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.
Claim 3
Dependent Claim
51 words
An ice skate as claimed in claim 1, wherein the top portion of said runner includes a longitudinally extending horizontal web portion fixedly secured to said runner to form a generally unitary portion thereof, each of said halves including recesses receiving an associated portion of said web in a tight-fit fashion.
Claim 4
Dependent Claim
46 words
An ice skate as claimed in claim 1, wherein said runner is provided with a plurality of holes extending transversely of the thickness of the runner and receiving plastic lugs in a tight-fit fashion, each of said lugs being unitary with one of said two halves.
Claim 5
Dependent Claim
38 words
An ice skate as claimed in claim 1, wherein said one of said halves is a unitary part including both of said flange portions and a substantial portion of the supporting column sections of the respective flange portion.
Claim 6
Dependent Claim
109 words
An ice skate as claimed in claim 1, wherein said column section of said one half is cut-out at one side thereof near the lower end of same to produce openings in one side of each of the associated column portions at the lower end thereof, said opening being each adapted to receive a correspondingly shaped section of the other half, to produce a joinder between said two halves, said joinder being a part of said joint, whereby a portion of said joint associated with the column portion diverts from said generally longitudinal direction of the remaining portions of the joint, to follow a locus coincident with said joinder.
