Abstract
Abstract A skate has a blade curved throughout its length to define a convex running edge. A pair of wall members have lower edges that are connected to the blade throughout its length, such wall members extending upwardly from the blade while diverging from each other. Horizontal flanges extend from upper edges of the wall members for securing to a boot sole to form a triangular structure therewith at least at front and rear portions of the skate and preferably the entire length thereof. The blade and said wall member define rounded end surfaces at the front and rear ends of the skate. Also disclosed is a combination skate and boot in which a molded plastic body forms a unitary structure defining a boot portion and a support portion. The support portion is triangular and projects downwardly from the boot portion while tapering inwardly to the socket in which the blade is mounted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
144 words
A skate comprising a. a blade curved throughout its length in a longitudinal plane to define a convex running edge, b. a pair of wall members having lower edges connected to said blade throughout its length, c. said wall members extending upwardly from said blade while diverging from each other, and d. horizontal flanges extending from upper edges of said wall members for securing to a boot sole to form in cross-section a triangular structure therewith at least at front and rear portions of the skate, e. wherein said wall members have upturned, vertically extending, lower edge portions abutting side portions of the blade with inturned, horizontally extending edges abutting an upper surface of the blade, said upturned portions and inturned edges, copperating to form an elongated socket having a curvature corresponding to that of said blade, said blade being secured within said socket.
Claim 2
Dependent Claim
144 words
A skate comprising a. a blade curved throughout its length in a longitudinal plane to define a convex running edge, b. a pair of wall members having lower edges connected to said blade throughout its length, c. said wall members extending upwardly from said blade while diverging from each other, and d. horizontal flanges extending from upper edges of said wall members for securing to a boot sole to form in cross-section a triangular structure therewith at least at front and rear portions of the skate, e. wherein said wall members have upturned, vertically extending, lower edge portions abutting side portions of the blade with inturned, horizontally extending edges abutting an upper surface of the blade, said upturned portions and inturned edges, copperating to form an elongated socket having a curvature corresponding to that of said blade, said blade being secured within said socket.
Claim 3
Dependent Claim
18 words
A skate according to claim 1, wherein said blade has a uniform width throughout its entire vertical dimension.
Claim 4
Dependent Claim
48 words
A skate according to claim 1, wherein said wall members diverge from each other from the blade to said upper edges throughout the entire length of the skate, the spacing apart of said upper edges increasing continuously from the rear portion to the front portion of the skate.
Claim 5
Dependent Claim
61 words
A skate according to claim 1, wherein said wall members converge to form a blunt rounded end surface at each end of the skate, each said rounded end surface being substantially vertically aligned with an end of the blade whereby penetration of an object struck by a blade end is essentially limited to the rounded end surface of the wall structure.
Claim 6
Dependent Claim
60 words
A skate according to claim 1, wherein said wall members converge to form a blunt rounded end surface at each end of the skate, each said rounded end surface defining a blunt edge sloping upwardly and longitudinally inwardly towards said boot sole, each end of the blade terminating flush with a sloping line defined by a respective said blunt edge.
Claim 7
Dependent Claim
108 words
A skate comprising a. a blade curved throughout its length in a longitudinal plane to define a convex running edge, and b. a pair of wall members diverging upwardly from said blade for securing to a boot sole, c. said wall members having upturned, vertically extending, lower edge portions abutting side portions of the blade with inturned, horizontally extending edges abutting an upper surface of the blade, said upturned portions and inturned edges cooperating to form an elongated socket having a curvature corresponding to that of said blade and within which said blade is secured, d. wherein said blade has a uniform width throughout its entire vertical dimension.
Claim 8
Dependent Claim
108 words
A skate comprising a. a blade curved throughout its length in a longitudinal plane to define a convex running edge, and b. a pair of wall members diverging upwardly from said blade for securing to a boot sole, c. said wall members having upturned, vertically extending, lower edge portions abutting side portions of the blade with inturned, horizontally extending edges abutting an upper surface of the blade, said upturned portions and inturned edges cooperating to form an elongated socket having a curvature corresponding to that of said blade and within which said blade is secured, d. wherein said blade has a uniform width throughout its entire vertical dimension.
Claim 9
Dependent Claim
61 words
A skate according to claim 6, wherein said wall members converge to form a blunt rounded end surface at each end of the skate, each said rounded end surface being substantially vertically aligned with an end of the blade whereby penetration of an object struck by a blade end is essentially limited by the rounded end surface of the wall structure.
Claim 10
Dependent Claim
60 words
A skate according to claim 6, wherein said wall members converge to form a blunt rounded end surface at each end of the skate, each said rounded end surface defining a blunt edge sloping upwardly and longitudinally inwardly towards said boot sole, each end of the blade terminating flush with a sloping line defined by a respective said blunt edge.
Claim 11
Dependent Claim
128 words
A skate comprising a. a blade, b. an upwardly diverging wall structure rigidly connected to said blade and having means for securing to a boot sole, c. said wall structure having outer surfaces that extend between the blade and the securing means while extending forwardly along both sides of each end of the skate to converge and come together to form a blunt rounded end surface constituting an integral part of the wall structure, d. each said blunt end surface being smoothly rounded in a plane normal to the said outer surfaces, and e. each said rounded end surface being substantially vertically aligned with an end of the blade whereby penetration of an object struck by a blade end is essentially limited by a said rounded end surface.
Claim 12
Dependent Claim
