Abstract
An ice skate guard with a sharpener. The ice skate guard has a housing with a channel and a sharpener. The channel extends along the housing, and receives a skate blade. The sharpener is mounted in the housing and extends into the channel. When a skate blade is drawn through the channel the sharpener engages with the blade and sharpens the blade.
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.
