<p>ICE SKATE SHARPENER The invention comprises an improved ice skate grinding, sharpening and contouring machine. The machine includes novel means to accurately center an ice skate between the heel and sole struts in a movable holding fixture and means to select the best contour position on the blade as a function of intended skate usage. As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman. The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount. Means to adjust the blade position relative to the blade holding fixture for pitching are disclosed in one embodiment. In an alternative embodiment means for pitching the entire fixture as desired are disclosed. Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater. New hockey skates with unconventional molded plastic struts such as the Canadian TUUK 2000 have entered commerce. Such skates are accommodated by a modified fixture, for positioning the blade center location that is equivalent to the center location of a hockey skate with conventional struts.</p> |
