Description




FIELD OF THE INVENTION




The present invention relates to ice skate guards. In particular, the present invention relates to an ice skate guard with a sharpener.




BACKGROUND OF THE INVENTION




Skate blades may require frequent sharpening, depending on the frequency of use. Skate blades can become dull or damaged not only with normal use but also if they come into contact with a hard surface, such as a concrete floor or a rock.




Many skate sharpening devices are known. Traditional shop skate sharpening utilises a horizontally disposed grinding wheel. The skate is mounted in a clamp with the blade horizontal. The center of the blade is placed at the same elevation as the center of the wheel and the blade is run along the grinding wheel for sharpening. These sharpeners are not portable and require the skate owner to take the skates to the shop, which is inconvenient and can prove costly if the skates require frequent sharpening.




U.S. Pat. No. 5,167,170 discloses an ice skate support sharpening apparatus. The apparatus is a bag that contains a central cavity with a left and a right flap. Within each flap is an ice skate support member with a “v” shaped groove, for receiving the ice skate blade, containing a sharpening stone. The apparatus can be adapted to contain fluid reservoirs that transport a fluid, such as a lubricant oil, to the “v” shaped grooves. The apparatus can be cumbersome for a user to transport as it adds additional “luggage” to the user's equipment. The apparatus requires the user to pass the skate through an opening and place it in the “v” shaped groove within the enclosure of the bag, which may prove awkward for the user.




Portable hand-held sharpeners are known. These devices usually have an elongated slot, for receiving the skate blade, with honing stones for sharpening the blade.




U.S. Pat. No. 5,499,556 discloses a portable ice skate blade sharpener with two elongated slots. A first slot contains a honing stone at the bottom of the slot for sharpening the blade and the a second slot contains opposing honing stones along the side walls for deburring the skate blade. The process requires two steps for sharpening and deburring the blade which may be time consuming for the user. The device may also be lost amongst equipment or left behind after use.




Skate guards are known. Traditional skate guards are used to protect the skate blade when not in use and to allow the user to walk in the skate on a non-ice surface.




U.S. Pat. No. 4,673,196 discloses a guard for skate, made from a flexible material, for allowing the user to walk on a non-ice surface. The guard has a body that contains a groove that has fins extending from the interior walls. When the blade is placed in the groove the fins are deflected downwards securing the blade in place. The bottom side of the body is concave downwards and, when pressure is applied by the user, exerts a force that narrows the top of the groove providing further pressure on the blade to secure it in position.




U.S. Pat. No. 5,941,568 discloses a skate guard that has a guard bar with a channel and a heel block. The channel narrows at the toe end to exert a pressure that holds the skate blade securely. The blade is inserted into the guard with the heel portion first followed by the toe, a spring exerts tension on the guard to hold the blade in place. When the blade is in place the blade's runner edge is held with minimum contact with the guard in order to protect the blade edge.




These skate guards merely provide protection for the skate blade in between required sharpenings. It is therefore desirable to provide an ice skate guard that contains a sharpening device. It is further desirable to provide a skate guard that contains a sharpening device that allows the user to sharpen the blade of the skate whilst protecting the blade and allowing the user to walk on a non-ice surface.




SUMMARY OF THE INVENTION




According to the present invention, there is provided an ice skate guard having a housing that includes a channel and a sharpener. The channel extends along the housing and receives a skate blade. The sharpener is mounted to the housing and extends into the channel to engage the skate blade as the skate blade is drawn through the channel.




According to one embodiment of the present invention the sharpener has two opposing stones.




According to a further embodiment of the present invention the ice skate guard has an actuator that is connected to the sharpener for urging the stones against the skate blade.




According to a further embodiment of the present invention the actuator has two opposing push buttons.




According to a further embodiment of the present invention the ice skate guard has a resilient biasing means that acts between the housing and the sharpener.




According to a further embodiment of the present invention the resilient biasing means has two opposing springs.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to

FIG. 1

, an ice skate guard is indicated generally by reference


20


. In a presently preferred embodiment the ice skate guard


20


includes a housing


22


and a sharpener


24


.




In the presently preferred embodiment the housing


22


has a substantially rectangular base


28


, opposed longitudinal side walls


30


,


32


and end portions


34


,


36


. The end portion


34


protrudes from the base


28


and is shaped for accommodating the toe portion of an ice skate blade. The end portion


34


contains the sharpener


24


. The end portion


36


protrudes from the base


28


, at the opposing end from the end portion


34


, and is shaped for accommodating the heel portion of an ice skate blade. The housing


22


has a channel


38


for receiving an ice skate blade


40


. The Channel


38


has a width corresponding to the thickness of the ice skate blade


40


, and a length corresponding to the length of the ice skate blade


40


. The Channel


38


may be generally continuous through the end portion


34


.




The Sharpener


24


includes a pair of opposed sharpening stones


25


disposed on either side of the Channel


38


. The stones


25


are moveable toward each other into a sharpening configuration engaging the sides of the skate blade


40


as illustrated in FIG.


3


. Push buttons


26


extending through the sharpener


24


are illustrated as a suitable actuator for moving the stones


25


into the sharpening configuration.




The stones


25


may be moveable away from each other and the blade


40


into a non-sharpening configuration, as illustrated in

FIG. 2

, by the action of a biasing means such as leaf springs


27


. The leaf springs


27


are mounted to the housing


22


and are resiliently deformed, as shown in

FIG. 3

by the action of the push buttons


26


. Upon release of the push buttons


26


, leaf springs


27


restore themselves and urge the stones


25


out of engagement with the blade


40


. The leaf springs


27


may advantageously be a SAE1050 grade spring steel clip.




The skate blade


40


can be placed in a sharpening positioning when being placed in skate guard


20


and/or when being removed from the skate guard


20


or as frequently as the user requires. To engage the sharpener


24


in the sharpening position the user simply applies a force to the actuator


26


which applies pressure on the opposing stones


25


pressing them against the skate blade


40


and runs the skate blade


40


along the stones


25


.




Referring now to

FIG. 4

, the skate blade


40


is illustrated in the process of being sharpened. The skate blade


40


is drawn through the end portion


34


to be received by the channel


38


. The user applies pressure to the actuator


26


which applies pressure to the opposing stones


25


and presses them against the skate blade


40


. The pressure is applied continuously as the skate blade


40


is drawn through the end portion


34


to be received by channel


38


. Upon completion, the user releases the pressure applied to the actuator


26


and the resilient biasing means


27


returns the opposing stones to the non-sharpening position.




It will be appreciated that variations may be possible to the presently preferred embodiment, while staying within the scope of the present invention, for example: another resilient biasing means such as coil springs might be used in lieu of the leaf springs


27


; one of the stones


25


may be fixed and the action of the opposite stone


25


relied upon to press the skate blade


40


into engagement with the fixed stone


25


; the stones


25


may be biased toward the sharpening configuration by a spring as long as the stones


25


are provided with a suitable camming surface to urge them apart in response to insertion of the skate blade


40


; less preferably, a single stone


25


might be used and the skate blade


40


reversed for sharpening its opposite face; and, the housing can be comprised of two identical halves with a spring for holding them together, as taught in U.S. Pat. No. 4,392,674.




The above-described embodiments of the invention are intended in an illustrative rather than a restrictive sense and alterations and modifications may be effected thereto, by those of skill in the art, without departing from the spirit and scope of the invention which is defined solely by the claims appended hereto.
