Double Bowed Ice Skate Blade With Elongated Ice Contract Point

Abstract

The present invention is a double-bowed ice skate blade having an attachment section with a constant thickness and a blade section with a continually variable thickness, with the thickest segments occurring at the toe-end and heel-end of the blade. The center section of the contoured ice skate blade has a large radius, creating a flatter blade with a greater length of the blade in contact with the ice. At the toe-end and heel-end of the contoured ice skate blade, the radius of the blade is smaller, resulting in a more curved blade, and less length of the ice-contacting surface of the blade in physical contact with the ice. Because the segments of smaller radius are thicker, a greater cross-sectional area of the ice-contacting surface of the blade is in contact with the ice at the toe-end and heel-end of the blade.

What is claimed is: 
     
         1 . A ice skate blade comprised of:
 a bottom surface adapted for planar contact with an ice surface;   a blade section;   a transition section; and   an attachment section.   
     
     
         2 . The apparatus of  claim 1  wherein said ice skate blade is double-bowed. 
     
     
         3 . The apparatus of  claim 1  wherein said transition section is disposed at the middle of said skate blade. 
     
     
         4 . The apparatus of  claim 1  wherein said transition section provides a material transition between said blade section and attachment section. 
     
     
         5 . The apparatus of  claim 1  wherein said blade section is a single piece, 
     
     
         6 . The apparatus of  claim 1  wherein said blade section is comprised is comprised of two separate pieces which are structurally connected at an connection interface. 
     
     
         7 . The apparatus of  claim 1  wherein said connection interface is comprised of interface selected from a group consisting of using welded material, brazed material, adhesive material and geometrically interlocking components. 
     
     
         8 . The apparatus of  claim 1  wherein said attachment section is a constant thickness. 
     
     
         9 . The apparatus of  claim 8  wherein said attachment is constant is selectively attached to a user-selected skate boot known in the art. 
     
     
         10 . The apparatus of  claim 1  wherein said attachment section includes at least one attachment. 
     
     
         11 . The apparatus of  claim 1  wherein said blade section has a varying thickness along the length of said blade section, 
     
     
         12 . The apparatus of  claim 1  wherein near the heel-end and toe-end of said blade section, blade section is thicker. 
     
     
         13 . The apparatus of  claim 12  wherein said blade section tapers inward toward the center of blade section 
     
     
         14 . The apparatus of  claim 12  wherein the bottom surface of said blade surface is thicker near the heel-end and toe-end than in the center of bottom surface. 
     
     
         15 . The apparatus of  claim 1  wherein said section has an exterior side and an interior side which are mirrors of each other. 
     
     
         16 . The apparatus of  claim 1  wherein said section has an interior edge and an exterior edge. 
     
     
         17 . The apparatus of  claim 16  wherein said interior edge and said exterior edge are determined by selective user weight distribution. 
     
     
         18 . The apparatus of  claim 1  wherein either said interior edge of said skate blade and said exterior edge of said are in contact with an ice surface, and center portion of said skate blade are simultaneously in contact with said ice surface. 
     
     
         19 . The apparatus of  claim 1  wherein the curvature of said skate blade creates an elongated exterior or interior skate edge. 
     
     
         20 . The apparatus of  claim 1  wherein said blade section further includes a chamfer between said blade section and said attachment section. 
     
     
         21 . The apparatus of said  claim 1  is comprised of portions of varying different radii.
