A skate blade sharpening system includes a chassis and an elongated slot for receiving a skate blade, and a skate blade retention mechanism to retain the skate blade in the sharpening position. A grinding wheel moves along the slot including the lower edge of the skate blade during sharpening. One or more slot covers are mounted to the chassis at respective ends of the slot. The slot covers are movable between covering and non-covering positions. In the non-covering positions the slot covers uncover the slot sufficiently to permit insertion and removal of the skate blade. In the covering positions, the slot covers cover end portions of the slot adjacent the ends of the skate blade to avoid exposing the user and mechanical components of the sharpening system to unsafe operating conditions.

1. A skate blade sharpening system, comprising: a chassis having an elongated slot for receiving a skate blade into a sharpening position;a skate blade retention mechanism configured to retain the skate blade in the sharpening position;a grinding wheel configured for movement along the slot including a lower edge of the skate blade in a sharpening operation; anda slot cover mounted to the chassis and being movable between a covering position and a non-covering position, the slot cover in the non-covering position uncovering the slot sufficiently to permit insertion and removal of the skate blade, the slot cover in the covering position covering a portion of the slot adjacent one end of the skate blade to avoid exposing a user and mechanical components of the sharpening system to unsafe operating conditions. 2. The skate blade sharpening system of claim 1, wherein the covering position is an inward position adjacent the end of the skate blade, and the non-covering position is an outward position away from the end of the skate blade. 3. The skate blade sharpening system of claim 2, wherein the slot cover is slidably mounted to the chassis and is slidable between the outward position and the inward position. 4. The skate blade sharpening system of claim 3, wherein the slot cover is slidably mounted to a top surface of the chassis. 5. The skate blade sharpening system of claim 3, wherein the slot cover and chassis are connected such that the slot cover can both resist movement and be movable relative to the chassis. 6. The skate blade sharpening system of claim 5, wherein resistance to movement is supplied by a locking mechanism. 7. The skate blade sharpening system of claim 6, wherein the locking mechanism includes a pawl-and-ratchet mechanism for which (i) a pawl is mechanically engaged with a ratchet in the locked position, and (ii) the pawl is mechanically disengaged from the ratchet in the unlocked position. 8. The skate blade sharpening system of claim 1, wherein the slot cover includes a sensing component adapted to be engaged by a blade holder of the skate blade when the skate blade is in the sharpening position and the slot cover is in the covering position. 9. The skate blade sharpening system of claim 8, wherein the sensing component provides an indication to a controller of the skate blade sharpening system enabling the controller to selectively enable and disable sharpening operation. 10. The skate blade sharpening system of claim 8, wherein the sensing component includes a mechanical member moving between a first position and a second position, the mechanical member being in the first position when the sensing component is not engaged by the blade holder, the mechanical member being in the second position when the sensing component is engaged by the blade holder. 11. The skate blade sharpening system of claim 10, wherein the mechanical member is a bumper having a face portion pushed by the blade holder to move the bumper from the first position to the second position. 12. The skate blade sharpening system of claim 11, wherein the bumper is a pivoting member also having a switch-engaging portion, the sensing component further includes an electrical switch engaged by the switch-engaging portion when the bumper is in the second position, and the indication provided by the sensing component is a change of state of the electrical switch. 13. The skate blade sharpening system of claim 12, wherein the change of state of the electrical switch is a change to an electrically closed condition. 14. The skate blade sharpening system of claim 12, wherein the change of state of the electrical switch is a change to an electrically open condition. 15. The skate blade sharpening system of claim 10, wherein the sensing component further includes a biasing member biasing the mechanical member into the first position, the biasing being overcome to move the mechanical member to the second position when the sensing component is engaged by the blade holder. 16. The skate blade sharpening system of claim 1, wherein the slot cover is one of a pair of slot covers mounted to the chassis and being movable between respective covering positions and non-covering positions, the slot covers in the non-covering positions uncovering the slot sufficiently to permit insertion and removal of the skate blade, the slot covers in the covering positions covering respective portions of the slot adjacent respective ends of the skate blade to avoid exposing the user and mechanical components of the sharpening system to unsafe operating conditions. 17. The skate blade sharpening system of claim 1, wherein the grinding wheel is located in an interior space of the skate blade sharpening system adjacent to an interior surface of the chassis, and the slot cover is mounted to the chassis. 18. The skate blade sharpening system of claim 1, wherein the slot cover is mounted to an exterior surface of the chassis.
