Abstract
A skate including a tongue mounted to a boot of the skate. The tongue has an upper end and a lower end, and a medial edge and a lateral edge, and a longitudinal center axis of the tongue extends between the upper and lower ends and is spaced equidistantly between segments of the medial and lateral edges. The longitudinal center axis divides the tongue into a medial segment and a lateral segment. The medial and lateral segments are asymmetrical about the longitudinal center axis.

DETAILED DESCRIPTION
[0059]
[0060]
[0061] The tongue 30 is adapted to fit between the medial and lateral sides 18B, 18C of the shell 18. The tongue 30 is thus located in part within the shell 18 of the boot 12, such that the tongue 30 covers the top surface T and the front ankle portion of the foot F. The tongue 30 is engaged with the shell 12. In the depicted embodiment, the tongue 30 is removably connected to the toe cap 23 or toe portion 20, however the tongue 30 may also, in another embodiment, be more permanently fixed (such as by sewing, stitching, bonding, etc.) to the shell 18 of the boot 12. The tongue 30 has an inner surface 30A to face towards, and abut against, the top surface T of the foot F, and an exposed outer surface 30B facing away from the foot F. The tongue 30 is elongated, and extends along a length defined between an upper end 32 and a lower end 33. A longitudinal center axis 31 extends along the length of the tongue 30 between its upper end 32 and lower end 33. As will be seen, the longitudinal center axis 31 of the tongue 30 is spaced substantially equidistantly between a medial edge 34A and a lateral edges 34B, at at least one point along length of the tongue 30. This may be, for example, at either of the upper and lower ends 32, 33, or at any one or more points therebetween.
[0062] The upper end 32 is positioned closer to the shin of the wearer when the skate 10 is worn, and the lower end 33 is positioned adjacent to the toes. The boot 12 includes a lace 19 that extends through lace eyelets 19A in the medial and lateral sides 18B, 18C of the shell 18 in a criss-crossing pattern. As such, when the lace 19 is tightened, the lace 19 acts to keep the tongue 30 in place against the foot F.
[0063]
[0064] The longitudinal center axis 31 is an approximate centerline or midline of the tongue 30, and extends between the upper and lower edges 34C,34D. The longitudinal center axis 31 (sometimes referred to herein as simply the center axis 31) is spaced apart from both the medial and lateral edges 34A,34B. The center axis 31 is spaced equidistantly between some segments 35 of the medial and lateral edges 34A,34B. The segments 35 are portions of the medial and lateral edges 34A,34B which are located at roughly the same position along the longitudinal span of the tongue 30. As described in greater detail below, other portions or segments of the medial and lateral edges 34A,34B, which are also located at roughly the same position along the longitudinal span of the tongue 30, are not equidistantly spaced from the center axis 31. It will therefore be appreciated that the center axis 31 is an axis of asymmetry for the tongue 30.
[0065] Still referring to
[0066] The point P3 shown in
[0067] It will therefore be appreciated that at some points P1,P2 on the center axis 31, the lateral and medial segment widths WL,WM are equal, and at other points P3 on the center line 31, the lateral and medial segment widths WL,WM are different and not equal. The widths of the medial and lateral segments 36,38 are therefore not constant at all points along the center axis 31. The widths of the medial and lateral segments 36,38 when measured from at least one same point P3 on the center axis 31 are different. The tongue 31 is therefore asymmetric or not symmetric about its longitudinal center axis 31 because the medial and lateral segments 36,38 are dissimilar. The shape of the medial and lateral segments 36,38 is not the same across the longitudinal center axis 31.
[0068] The asymmetric tongue 30 disclosed herein may be better able to conform to the anatomy of the foot F, and may also provide increased comfort for the wearer of the skate 10. Features of the tongue 30 which contribute to its asymmetry are described in greater detail below. These features may be considered to be comfort features because they may improve the comfort of the wearer of the skate 10. The examples of comfort features described below are present at locations of the tongue 30 in both the medial and lateral segments 36,38. It will be appreciated that the tongue 30 may have only one of the comfort features described below, and that this sole comfort feature may be disposed in only one of the medial and lateral segments 36,38.
[0069] One of the comfort features of the tongue 30 which contributes to its asymmetry is shown in
[0070] Another one of the comfort features of the tongue 30 which contributes to its asymmetry is also shown in

[0074] Each of the tongues 130,130 includes the tab 140 extending outwardly from the lateral edge 134B. The tab 140 and its distal peripheral edge 141 are insertable between the top surface T of the foot F and an underside of the lateral side portion 18B of the shell 18. The tab 140 is thus an extension at or near the upper end 132 of each tongue 130,130, on their lateral sides, which helps to reduce or prevent frictional rubbing between the lateral side portion 18B of the shell 18 and an upper portion of the top surface T of the foot F.
[0075] Each of the tongues 130,130 has the protrusion 144 extending from the inner surface 130A towards the top surface T of the foot F. The protrusion 144 is located toward the lower end 133 of each tongue 130,130, and is positioned closer to the lower end 133 than to the upper end 132. The protrusion 144 overlays a portion of the foot F which corresponds to the location of the lateral metatarsal bones 11B of the foot F (see
[0076] Each of the tongues 130,130 includes the folding zone 142 extending across the width of each tongue 130,130 between the medial and lateral edges 134A,134B. The upper and lower ends 132,133 of each tongue 130,130 are foldable towards one another about the folding axis 142A. The folding zone 142 therefore helps to flex each tongue 130,130, and in particular, helps in dorsiflexion and plantarflexion of the ankle of the wearer. The folding axis 142A is positioned above the top surface T of the foot F and in alignment with the dorsiflexion-plantarflexion axis of the foot F.
[0077] The skate 10 disclose herein provides a tongue 30,130 having an anatomical design so that the tongue 30,130 may better conform to the foot F. This improved conformity of the tongue 30,130 may help the tongue 30,130 to remain in place during the skating motion. The tongue 30,130 may therefore provide increased comfort to the wearer.
[0078] The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without departing from the scope of the invention disclosed. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in light of a review of this disclosure, and such modifications are intended to fall within the appended claims.
