Abstract

A skate blade sharpening system used to sharpen the blades of ice skates. The skate sharpener can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The housing can include at least one slot cover to engage the skate blade. Engagement of the skate blade can be sensed by a controller to enable sharpening operations to proceed. The skate blade sharpening system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade a desired number of times to sharpen the skate blade.

Claims (40)

1 . A skate blade sharpening system comprising:

a grinding motor configured to rotate a grinding component mounted at a mounting location, the grinding component having an outer surface dimensioned and configured to grind a bottom edge of a skate blade during a grinding operation, and the grinding component including an identification tag having interface circuitry and memory including a usage location configured to store a usage tracking value;

a transceiver configured to communicate with the interface circuitry of the identification tag, and to read from and write to the usage location; and

a controller configured to:

control operation of the grinding motor and perform grinding operations, wherein the grinding component is configured to be translated longitudinally relative to the bottom edge of the skate blade during grinding operations;

read, using the transceiver, a current usage tracking value from the usage location;

control sharpening operations based, at least in part, on the current usage tracking value; and

write, using the transceiver, an update to the current usage tracking value based, at least in part, on usage of the grinding component during grinding operations.

2 . The skate blade sharpening system of claim 1 , wherein the controller is further configured to selectively enable or disable grinding operations based, at least in part, on the current usage tracking value.

3 . The skate blade sharpening system of claim 2 , wherein the controller is configured to initiate the grinding operation based on input received from a remote system.

4 . The skate blade sharpening system of claim 1 , wherein the usage tracking value indicates usage of the grinding component, and wherein the controller is configured to update, via the transceiver, the usage tracking value based, at least in part, on usage of the grinding component during grinding operations.

5 . The skate blade sharpening system of claim 4 , wherein the usage tracking value indicates usage of the grinding component based on usage parameters.

6 . The skate blade sharpening system of claim 4 , wherein the controller is configured to update the usage tracking value prior to the grinding operation.

7 . The skate blade sharpening system of claim 4 , wherein the controller is configured to update the usage tracking value after the grinding operation is complete.

8 . The skate blade sharpening system of claim 4 , wherein the identification tag is located on the grinding component such that the identification tag rotates with the grinding component during the grinding operation, and wherein the transceiver is configured to engage in wireless communication with the transceiver during the grinding operation as the grinding component rotates.

9 . The skate blade sharpening system of claim 4 , wherein the transceiver is configured to engage in wireless communication with the transceiver when the grinding component is stationary.

10 . The skate blade sharpening system of claim 4 , wherein the usage tracking value indicates usage of the grinding component as a number of passes performed by the grinding component during grinding operations.

11 . The skate blade sharpening system of claim 10 , wherein the controller is configured to update the usage tracking value after a defined number of passes during the grinding operation.

12 . The skate blade sharpening system of claim 1 , wherein the transceiver is a radio frequency identification (RFID) transceiver, and wherein the transceiver is configured to communicate with the identification tag using RFID communication protocols.

13 . The skate blade sharpening system of claim 1 , further comprising a lighting component configured to illuminate an interior of a housing of the skate blade sharpening system.

14 . The skate blade sharpening system of claim 13 , wherein the lighting component is configured to output different visual indications for different operational states of the skate blade sharpening system.

15 . The skate blade sharpening system of claim 14 , wherein the visual indications include light of different colors, and wherein each operational state of the skate blade sharpening system is associated with a different color.

16 . The skate blade sharpening system of claim 15 , further comprising a door configured to provide access to the interior of the housing and a door switch configured to determine whether the door is in an open position or a closed position, wherein the controller is further configured to prevent operation of the skate blade sharpening system when the door is in the open position.

17 . The skate blade sharpening system of claim 16 , wherein the door includes a latch, and wherein the controller is further configured to lock the door in the closed position during the grinding operation of the skate blade sharpening system.

18 . The skate blade sharpening system of claim 16 , wherein the door includes a transparent panel, wherein the interior of the housing of the skate blade sharpening system is visible through the transparent panel, and wherein the visual indications output by the lighting component are visible through the transparent panel.

19 . A method of operating a skate blade sharpening system, the method comprising:

receiving an input to perform at least one grinding operation with a grinding component using the skate blade sharpening system, the grinding component including an identification tag having interface circuitry and memory including a usage location configured to store a usage tracking value;

communicating, using a transceiver of the skate blade sharpening system, with the interface circuitry of the identification tag to read a current usage tracking value from the usage location;

determining whether to perform the at least one grinding operation based at least in part, on the current usage tracking value;

in response to a determination to initiate the at least one grinding operation, performing the at least one grinding operation with the grinding component, wherein the grinding component is configured to be translated longitudinally relative to a bottom edge of a skate blade during grinding operations, the grinding component having an outer surface dimensioned and configured to grind the bottom edge of the skate blade; and

communicating, using the transceiver, with the interface circuitry of the identification tag to write an update to the usage tracking value based, at least in part, on the at least one grinding operation.

20 . The method of claim 19 , further comprising disabling the at least one grinding operation based, at least in part, on the current usage tracking value.

21 . The method of claim 19 , wherein the determination to initiate the at least one grinding operation is based, at least in part on, input received from a remote system.

22 . The method of claim 19 , wherein the update to the usage tracking value is performed prior to the at least one grinding operation.

23 . The method of claim 19 , wherein the update to the usage tracking value is performed after the at least one grinding operation is complete.

24 . The method of claim 19 , wherein the update to the usage tracking value is performed after a defined number of passes during the at least one grinding operation.

25 . The method of claim 19 , wherein communication between the transceiver and the interface circuitry occurs when the grinding component is rotating or stationary.

26 . The method of claim 19 , further comprising outputting different visual indications for different operational states of the skate blade sharpening system using a lighting component configured to illuminate an interior of a housing of the skate blade sharpening system.

27 . The method of claim 19 , further comprising preventing the at least one grinding operation from being performed when a door to an interior of the skate blade sharpening system is in an open position.

28 . The method of claim 27 , further comprising locking the door in a closed position during the at least one grinding operation.
