Abstract
In one aspect, the invention is directed to a sharpener for sharpening a snowice travel member such as a skate blade, a ski or a snowboard, which includes a sharpening surface that is movable lengthwise along an edge face of the item to be sharpened. The sharpening surface may be movable lengthwise by means of a motor and a reciprocating mechanism, or may be manually moved by a user.
Claims13
A sharpener, comprising:
- a body;
- a skate blade orienting structure, configured to orient a skate blade along a longitudinal direction line;
- a first sharpening surface positioned for sharpening a first corner edge of the skate blade and a second sharpening surface positioned for sharpening a second corner edge of the skate blade;
- and
- a drive mechanism configured to move the first and second sharpening surfaces reciprocally relative to the body along a reciprocation path along the longitudinal direction line, wherein the body includes an edge face positioning surface for receiving an edge face of the skate blade, and wherein the sharpener further includes a sharpening surface engagement biasing member that is configured to urge the first and second sharpening surfaces to the edge face.

A sharpener, comprising:
- a body including an edge face positioning surface for receiving an edge face of a skate blade;
- at least one sharpening surface positioned for sharpening a corner edge of the skate blade;
- a drive mechanism configured to move the at least one sharpening surface relative to the body;
- and
- a sharpening surface biasing member that, in use, is configured to urge the at least one sharpening surface to the edge face of the skate blade,
- wherein the at least one sharpening surface includes a first sharpening surface configured for sharpening a first corner edge of the skate blade and a second sharpening surface configured for sharpening a second corner edge of the skate blade.

A sharpener, comprising:
- a body including an edge face positioning surface for receiving an edge face of a skate blade;
- at least one sharpening surface positioned for sharpening a corner edge of the skate blade;
- a drive mechanism configured to move the at least one sharpening surface relative to the body;
- a sharpening surface biasing member that, in use, is configured to urge the at least one sharpening surface to the edge face of the skate blade;
- and
- at least one item engagement sensor positioned to sense the engagement of the skate blade with the sharpening surface,
- wherein the item engagement sensor is positioned to detect movement of the sharpening surface against the force of the sharpening surface engagement biasing member.

- a body including an edge face positioning surface for receiving an edge face of a skate blade;
- at least one sharpening surface positioned for sharpening a corner edge of the skate blade;
- a drive mechanism configured to move the at least one sharpening surface relative to the body;
- and
- a sharpening surface biasing member that, in use, is configured to urge the at least one sharpening surface to the edge face of the skate blade;
- and
- wherein the at least one sharpening surface is provided on a disposable element that is removably connectable to a non-disposable portion of the sharpener,
- wherein the disposable element is a sharpening base, and wherein the at least one sharpening surface and the sharpening surface biasing member are integral with each other,
- wherein the sharpening base includes a first wall and a second wall, wherein the at least one sharpening surface and the at least one sharpening surface biasing member are positioned on at least one tongue that extends from at least one of the first and second walls towards the other of the first and second walls.
