Ice skate blades and sharpening machines

摘要

A sharpening machine generally includes a grinding wheel having a perimeter that is rotatable about a first axis. The sharpening machine includes an adjustment device adapted to be coupled to a structure of the sharpening machine. A shaft, mounted to the adjustment device, defines a second axis that is generally parallel to the first axis when the adjustment device is coupled to the structure and is movable along a predetermined feed axis toward the grinding wheel. A carousel is rotatably connected to the shaft of the adjustment device. A contouring tool having a counter surface is rotatably connected to the carousel. Movement of the shaft of the adjustment device along the feed axis is configured to translate the carousel and move the contouring tool into and out of engagement with the grinding wheel to facilitate dressing of the perimeter of the grinding wheel to a grinding wheel contour.

主权项

1. An ice skate blade comprising:
a first side wall and a second side wall opposite the first side wall; a flat bottom disposed between the first side wall and the second side wall; a first flat formed between the flat bottom and the first side wall, the first flat forming a first flat angle with the flat bottom; a second flat formed between the flat bottom and the second side wall, the second flat formed adjacent the flat bottom on an opposite side of a center line from the first flat, the second flat forming a second flat angle with the flat bottom; a first bottom edge formed at a junction of the first side wall and the first flat; a second bottom edge formed at a junction of the second side wall and the second flat; a first vee formed from the first side edge, the first bottom edge, and the first flat, the first vee defines a first edge angle between the first flat and the first side edge; and a second vee formed from the second side edge, the second bottom edge, and the second flat, the second vee defines a second edge angle between the second flat and the second side edge, wherein a first line that extends parallel to the first flat intersects with a second line that extends parallel to the second flat, the first line intersects the second line at an intersection that is spaced from the center line.
