The technology relates to the general field of the sport of hockey, and has certain specific application to hockey, figure and goalie skate blades.
Hockey skate blades originally were thicker and had a metal holder for support of the blade. The technology evolved and they went to a plastic holder and a thinner blade made from hard carbon steel. The next stage was a plastic holder and a blade made from stainless steel. The carbon steel blades had a tendency to break while stainless steel has a tendency to bend when impacted. Current gages to determine if a skate blade is bent are multi-piece assemblies that are expensive. They will have a read out or they are combined with another function (sharpening, honing, blade holding for blade mounting, remove nicks or marrs). Usage with one hand, quickly, by the person with the skate on their foot is needed while participating in the sport or during a game.
The disclosed Skate Blade Flatness Gage will check a Skate Blade to see if it is bent, potentially broken or has large burrs. Bent, broken or burrs on skate blades will impede skating performance and the ability of the blade to be sharpened effectively.
It may be used by hockey skate sharpening professionals, personal skate blade sharpeners, hockey equipment managers, coaches, hockey players, figure skaters and anyone that skates recreationally.
Various embodiments of the invention are disclosed in the following detailed description and accompanying drawings.
A current hockey skate blade is made from multiple grades of steel and is 2.9 mm thick. Figure skates are typically thicker and goalie skates are typically 4.0 mm thick.
The Skate Blade Flatness Gage is a go/no go gage where by the skate blade is either pressed into the slot from the top with the blade parallel to the slot or inserted to the slot from the front to the back or back to the front. If any resistance is felt inserting or removing the blade into the slot from any direction, then the blade is bent.
It is made of a material that with has very low moisture absorption and a low coefficient of thermal expansion. The slot in the gage is 0.1″ to 10″ deep and is made to the thickness of the skate blade plus a tolerance for the amount you want the maximum delta from flatness of the blade. i.e. a 2.9 mm blade could have a 3.0 mm gap or up to 3.5 mm. The block can be (I″ to 20″ long)×0.1″ to 5″ high×0.1″ to 5″ wide. This product is made from Nylon for cost effectiveness and heat stability. The prototype Gage is made at a length of 10″ with a 1.5″ height and 1″ width to fit a majority of hockey skate blade lengths and be cost effective. It can be made of multiple lengths, widths and heights to cover specific blade lengths if necessary.
The depth of the slot can be of any depth to ensure the whole depth of the skate blade goes into the slot. The blade holder needs to bottom out in the slot to ensure the whole blade is checked for flatness.
The block is inserted on to the skate blade in multiple ways.
