Description

Double-Edged Skate Blade, Holder and Supports Related Field of Invention The double-edged skate blade, holder and supports are invented to provide ice hockey players a quick change from a dull skate blade to a sharpened skate blade. The aforementioned invention is comprised of four parts: the double-edged skate blade (tapered from toe to heel width-wise fashion), the holder that is fastened to the boot of the skate and the two supports which marry the skate blade and holder together.

Backaround Ice hockey skates today are comprised of a single sharpened skate blade fastened into a holder, which is not intended to be separated from its holder. This creates a time consuming operation when the blade is dull during a game. If a player has a dull skate using one of today's skate blades and holder assembly, that player must remove his entire skate and take it to the nearest skate sharpener to have it sharpened. This results in the loss of ice time the player has paid for. Many parents have children in hockey and have faced, or could face this type of problem with a modern ice skate blade and holder assembly.

Therefore, the intention of this invention is to provide a double-edged skate blade and holder assembly that is married by two supports (one on either side of the skate blade) which allows a quick removal and installation of the blade without having to remove the skate off of the foot.

Summary of Invention The invention is comprised of four parts: a double-edged skate blade, two skate blade supports connected or attached on each side of said blade; a skate holder attached to the boot of the skate, which is designed to lock the double-edged skate blade and supports in place with a locking mechanism.

The skate blade is sharpened on both extremities and tapered in a toe to heel fashion in a width- wise configuration along the blade. The double-edged skate blade will have one sharp edge which will be exposed out of the holder and come in contact with the ice surface. The other sharp edge will be safely enclosed inside of the holder. A tapered blade allows the ice skate to coast at faster speeds. Along the length of the equator there will be four apertures symmetrically cut out length-wise in a north-south fashion, which in turn makes the blade lighter while at the same time maintaining the balance of the blade. Also at a distance of approximately one third and two thirds as measured down the length starting from the toe (front) of the blade will be four individual cut-outs, each symmetrically above and below the equator; these apertures will permit the locking mechanism to pass through the blade.

The two supports are to provide strength and stability to the blade, as well as to marry the double-edged skate blade and holder together. The support will be four individual cut-outs each situated symmetrically above and below the equator, which are perfectly aligned with the four skate blade apertures situated approximately one third and two thirds down the length of the skate blade. The aforementioned supports will be fastened via a male-female connection to the double-edged skate blade. They will also have "gear-like teeth" that line up in the skate blade holder in four different locations which will aid the two supports to marry the double-edged skate blade tightly with the holder, and to not permit the blade and support assembly to move in a toe to heel fashion. Without these supporting devices the blade would be either too heavy or too weak to function properly and competitively on an ice hockey skate.

The skate holder of the above mentioned skate blade and support assembly will be fastened to the skate boot. The bottom of the skate blade holder is flat, as in a 180 degree configuration along the full length of the bottom edge of the double-edged skate blade holder. A
support post is aligned over the ball of the foot, thus keeping the strength, integrity, and torsional rigidity of the holder intact. The holder has four locations of "gear-like teeth" that results in the blade support assembly being tightly married to the holder. This scenario will not allow any movement from the skate blade and support assembly in a toe to heel fashion.
The holder will also have at a distance of approximately one third and two thirds of the length from the toe (front) of the skate holder two individual cut-outs, each above the flat, or 180 degree bottom of the holder. These apertures allow the placement of the locking mechanism; this locking mechanism stops the blade and support assembly from falling out of the holder when the skate is lifted off of the ice surface. Furthermore, the locking mechanism will be fastened from the inside wall of the skate blade holder to the outside wall. The holder will have two cut-outs to lighten the weight of the holder itself. The top deck is one solid piece from the toe to the heel with 6 "ribs"
going from one side to the other. This will strengthen the torsional rigidity of the holder. Also, the heel area and the area inside the post, which is positioned between the two large cut-outs of the holder are hollowed out to lighten the holder. The front of the holder is curved from the blade up to the top deck, and the back of the holder is also curved going from the back of the blade to the heel portion of the top deck. The bottom of the skate blade holder is slightly longer in length than the top deck. This holder is exclusively and uniquely designed to house the double-edged skate blade and support assembly. Variations of various cutouts, apertures, distances, lengths, widths, heights ( dimensions ) may vary according to the prerogative of the inventor Earl Arthur Dahlo as he sees fit in the invention process going forward of perfecting and or adjusting various configurations as previously alluded to.
