Portable skate sharpener

Abstract

A skate sharpening device is provided which allows a grinding device to rotate with respect to a working surface of the device in both a cross grind configuration and a finish grind configuration. The grinding device pivots about a pin and is guided by a threaded stud protruding through an arcuate slot and securable using a flared, hand operated nut. A slidable rack attached to the grinding device is moveable in fore and aft directions relative thereto. A dressing tool may be attached to the rack and its forward position is governed by an actuating system. The actuating system allows a user to selectively inhibit forward movement of the rack to position the dressing tool at a suitable position to allow a dressing bit to contact a grinding wheel attached to and powered by the grinding device to dress the grinding wheel.

1 . A skate sharpening device comprising a surface for supporting an ice skate during sharpening thereof; and a grinding device operating a grinding wheel, said grinding device being moveable relative to said surface between a first position to permit cross grinding of said skate and a second position to permit finish grinding of said skate.  
   
   
       2 . A skate sharpening device according to  claim 1  wherein said grinding device is supported by an upstanding wall extending from said surface and is rotatably attached to said wall for rotating said grinding device between said first and second positions.  
   
   
       3 . A skate sharpening device according to  claim 1  further comprising a handle extending from said grinding device for assisting in movement thereof between said first and second positions.  
   
   
       4 . A skate sharpening device according to  claim 1  wherein said surface comprising an aperture to permit movement of said grinding device between said positions, and further comprising a shield arranged to lie substantially flush with said surface over a portion of said aperture when said grinding device is in said second position.  
   
   
       5 . A skate sharpening device according to  claim 1  further comprising a dressing tool detachably supported by said grinding device, said tool comprising a bit for dressing said grinding wheel, said bit having an integral support for attaching said tool to said grinding device, said bit being moveable with respect to said grinding device; and an actuator for adjusting the position of said bit relative to said wheel to control the extent to which said grinding wheel is dressed.  
   
   
       6 . A skate sharpening device according to  claim 5  wherein said support comprises a yoke detachably connected to a rack, said rack being slidably secured to said grinding device, the position of said rack being controlled through adjustment of said actuator.  
   
   
       7 . A skate sharpening device according to  claim 6  wherein said actuator comprises an actuating member interacting with said rack to inhibit movement of said rack beyond a selectable position, said actuator further comprising a worm and dial operating with said actuating member to control movement thereof through rotation of said dial.  
   
   
       8 . A skate sharpening device according to  claim 1  further comprising an exhaust system for collecting shavings created when grinding said skate, said exhaust system including a coupling for attaching a vacuum thereto.  
   
   
       9 . A skate sharpening device according to  claim 10  wherein said exhaust system includes a port in said surface to collect said shavings when cross grinding said skate and a collection tube supported on said surface to collect said shavings when finish grinding said skate.  
   
   
       10 . A skate sharpening device according to  claim 11  wherein said port and said collection tube are connected to said coupling through a duct supported beneath said surface.  
   
   
       11 . A skate sharpening device according to  claim 1  wherein said surface is supported by a case, said case including a handle and wheels for transporting said device.  
   
   
       12 . A skate sharpening device according to  claim 11  wherein said handle is telescopic.  
   
   
       13 . A skate sharpening device according to  claim 1  further comprising a notch formed in said surface for attaching a contouring template.  
   
   
       14 . A skate sharpening device according to  claim 13  further comprising said contouring template detachably fixed in said notch.  
   
   
       15 . A dressing tool for attaching to a skate sharpening device, said skate sharpening device having a grinding device operating a grinding wheel, said tool comprising a bit for dressing said grinding wheel, said bit having an integral support for attaching said tool to said grinding device, said bit being moveable with respect to said grinding device; and an actuator for adjusting the position of said bit relative to said wheel to control the extent to which said grinding wheel is dressed.  
   
   
       16 . A dressing tool according to  claim 15  wherein said support comprises a yoke detachably connectable to a rack, said rack being slidably securable to said grinding device, the position of said rack being controlled through adjustment of said actuator.  
   
   
       17 . A dressing tool according to  claim 16  wherein said actuator comprises an actuating member interacting with said rack to inhibit movement of said rack beyond a selectable position, said actuator further comprising a worm and dial operating with said actuating member to control movement thereof through rotation of said dial.
