Abstract
A skate boot featuring an exterior toe protector and a method of manufacture. The skate boot is provided with a toe cover adapted to be pulled and stretched over a last allowing the skate boot to be formed in a similar fashion as a skate boot featuring an interior toe protector. The toe protector has a pair of lateral extensions which overlap the frontal edges of the lateral supporting portions of the skate boot and a pair of cutout areas to surround the same lateral supporting portions of the skate boot.
Description
FIELD OF THE INVENTION
The invention relates to skate boots, in particular to skate boots featuring an exterior toe protector, and to a method of manufacturing skate boots.
BACKGROUND OF THE INVENTION
Toe protectors are not new to the field of sports equipment and hockey in particular. Hockey skates are provided with a shell-like reinforcement in the toe region of the skate to prevent injuries. Canadian patent No. 839,484 discloses a skate boot construction including a toe cap. A molded convex dome-like shell is placed over the last and stapled to the insole of the boot; an upper toe covering flexible material is then placed over the last and over the toe cap and secured to the insole of the boot. This is the typical method of manufacturing a skate boot having a protective toe cap.
Most skate boots are normally manufactured in the following manner: A toe-cap is positioned on the last of the skate boot. A last is a three-dimensional shape of the inside cavity of the boot or shoe. A pre-assembled boot consisting of various pieces of fabric and/or leather is placed over the last and over the toe-cap. An insole is then placed on the bottom part of the last. The pre-assembled boot is stretched over the last and over the toe cap in order for the pre-assembled boot to conform to the specific shape of the last. The toe cap is therefore located inside the boot. The stretched material is then nailed or tacked and glued to the insole to maintain the desired shape. Once the upper part of the skate boot is completed, a rigid outsole is glued to the insole of the boot to complete the skate boot. An ice blade holder or an in-line roller chassis is then mounted to the rigid outsole to complete the skate.
More recently, skate boots have been made with the toe cap outside the skate boot. This method has the advantage of eliminating all material covering the toe cap of the skate boot. However, the stretching part of the manufacturing process had to be modified. The pre-assembled boot no longer required a toe cap covering material since it was no longer necessary to stretch this material over the toe cap. A tongue was sewn to the toe cap. The protective toe cap and tongue assembly was inserted between the sides of the pre-assembled boot and sewn to each side of the boot. The stretching over the last was done only along the sides and at the rear of the pre-assembled boot where material was then glued and nailed or tacked to the insole. Finally, an outsole was nailed and glued to the bottom of the skate boot covering the bottom of the toe cap previously installed.
The above described method of manufacturing a skate boot using an exterior toe cap produced an inferior formfitting skate boot in the frontal area of the foot. Skaters using skate boots having an exterior toe cap often complained about poor frontal fitting of this type of skate boot. The frontal area of the skate boot was not being stretched properly and the result was a somewhat awkward fitting skate, which was either too tight or too loose.
Thus, there is a need in the industry for a skate boot featuring an outside toe protector which has equal formfitting qualities as a traditionally made skate boot.
OBJECTS AND STATEMENT OF THE INVENTION
It is thus an object of the invention to provide a skate boot having an outside toe protector that has equal formfitting qualities as a traditionally made skate boot.
It is another object of the invention to provide a skate boot construction adapted to increase the frontal formfitting of a skate boot.
It is a further object of the invention to provide a method of making a skate boot having an outside toe protector which has a good frontal form fit.
As embodied and broadly described herein, the invention provides a skate boot comprising an upper for supporting and enclosing a skater's foot. The upper has a heel counter, an ankle support, a medial quarter and a lateral quarter, each quarter having a frontal edge; the medial and lateral quarters extending forwardly from the heel counter and the ankle support. An insole forms the bottom of the upper and a toe cover defining a toe box for covering the toe area of the skaters foot, is connected to the frontal edges and to the insole. A tongue is connected to the toe cover for cushioning and covering the upper frontal part of the skaters foot and ankle. The skate boot also comprises a preformed toe protector overlying the toe cover and secured to the upper. The toe protector has a convex upper portion covering the front, the top and the sides of the toe cover. The toe protector also has an anchoring portion for securing the toe protector to the upper.
Preferably, the toe protector further comprises a tab extending inwardly from each lateral extensions for fastening the toe protector to the insole of the upper. Also, the toe protector comprises cut-out areas adapted to surround the frontal edges of the medial and lateral quarters to allow some degree of motion to these quarters.
Advantageously, the toe cover comprises at least two superposed layers: a first layer of smooth material facing the inside of the skate boot and a second layer of a textile material over the first layer and adapted to resist tension.
As embodied and broadly described herein, the invention also provides a method of making a skate boot comprising the steps of:
a) stretching over a last an upper having a toe cover, a heel counter, an ankle support, an insole, a medial quarter and a lateral quarter;
b) folding the edges of said upper underneath said insole on said last and fastening said edges to said;
c) affixing a preformed toe protector over said toe cover, said toe protector having a convex upper portion covering the front, the top and the sides of said toe cover and an anchoring portion for securing said toe protector to said insole;
d)simultaneously urging both sides said toe protector toward said medial and lateral quarters and fastening said anchoring portion of said toe protector to said insole.
Other objects and features of the invention will become apparent by reference to the following description and the drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1
illustrates a pre-assembled upper
20
for making a skate boot. Pre-assembled upper
20
basically comprises a heel counter
61
, an ankle support
62
, a medial quarter
63
and a lateral quarter
64
. Each quarter
63
and
64
has a frontal edge
28
and
29
and extends from the heel counter
61
and the ankle support
62
to the front of the upper
20
. At the front, a toe cover
26
made of a soft textile material covers the toe area of the skater's foot and is sewn on each side to frontal edges
28
and
29
. A tongue
31
, for cushioning and covering the upper frontal part of the skater's foot and ankle, is also sewn to the upper edge of toe cover
26
in a manner enabling tongue
31
to be flipped up and down to open the skate boot and allow the skater to easily insert his or her foot into upper
20
.
Pre-assembled upper
20
is made of various pieces of leather, fabric or textile sewn and glued together prior to being formed as pre-assembled upper
20
.
FIG. 1
illustrates the first step of the making of a skate boot once pre-assembled upper
20
is completed. A Last
25
is inserted into pre-assembled upper
20
and an insole
36
is positioned over the lower end of last
25
once last
25
is inside pre-assembled upper
20
. Medial and lateral quarters
63
and
64
have a sufficient marginal edge
33
that exceeds all around last
25
to provide a gripping and pulling means to stretch upper
20
over last
25
. Similarly, toe cover
26
has a marginal edge
34
that exceeds the front portion of last
25
to provide the necessary gripping and pulling means to stretch toe cover
26
over the front portion of last
25
. Marginal edges
33
and
34
provide the necessary hold for pre-assembled upper
20
to be stretched over a last
25
.
FIGS. 2 and 3
illustrate the second step of making of a skate boot and shows last
25
inside upper
20
and insole
36
in position. Glue is first applied along the sides of insole
36
. Marginal edges
33
and
34
of pre-assembled upper
20
are then pulled and stretched tightly over last
25
and folded underneath insole
36
as depicted by the arrows A. Once folded, marginal edges
33
and
34
adhesively bond to insole
36
with the glue that was previously laid on insole
36
. Note that toe cover
26
is made of a material strong enough to resist the traction force of the stretching. Toe cover is preferably constructed of three layers of material: A first layer of smooth textile material on the inside of the boot which will be in contact with the skater's foot, a second layer consisting of a thin plastic sheet adapted to retain the shape given by the last
25
, and a third layer of a nylon textile which can resist the traction force during the lasting process. The addition of toe cover
26
to the construction of a skate boot having a external toe protector enables the entire pre-assembled upper
20
to be properly stretched over last
25
which will provide a good fitting of the final product. The pulling and stretching may be accomplished by hand using traditional shoe maker tools or can be automated to provide an even tension of the material over last
25
which results in a better quality skate boot.
As shown in
FIG. 4
, while being stretched and pulled, marginal edges
33
and
34
are further nailed or tacked all around insole
36
with nails or tacks
38
. Nails
38
provide the necessary mechanical grip to remove the pulling forces and allow the glue to properly set between marginal edges
33
and
34
and insole
36
. Once marginal edges
33
and
34
are fully stretched and firmly attached to insole
36
, a light sanding of the marginal edges
33
and
34
is performed to partially even the lower surface of upper
20
and provide a flat surface on which an outsole can later be glued and nailed.
FIG. 5
shows upper
20
in its final form. Toe cover
26
is stretched around insole
36
and shaped to define a toe box covering the toe area of the foot. Both lateral and medial quarters
63
and
64
are also stretched around insole
36
and shaped to support each side of the foot. A toe protector
40
is then positioned over toe cover
26
as represented by arrow
50
. Prior to positioning toe protector
40
, a layer of glue may be applied to toe cover
26
to ensure that cover
26
adheres to the interior wall of toe protector
40
. However toe cover
26
may also not be glued to the interior surface of toe protector
40
and remain loose inside the skate boot. As shown in
FIGS. 5 and 6
, toe protector
40
is a convex structure made of a highly resistant plastic such as nylon or polyurethane which are both rigid and light. Toe protector
40
features a generally planar lower insole contacting portion
42
or anchoring portion conforming to the frontal lower surface of upper
20
and flanked by a pair of tabs
44
extending from lower portion
42
. Lower portion
42
preferably extends over the entire frontal area of insole
36
but may also only extend along the edge of insole
36
leaving the center portion uncovered. In this manner, toe protector
40
is more flexible and can adapt to various widths.
The upper portion
45
that will cover the toe area of pre-assembled upper
20
features an upper extension
46
and two lateral extensions
48
. Each lateral extension
48
preferably includes a tab
44
adjacent lower portion
42
of toe protector
40
. Cutout areas
43
are provided in between lateral extensions
48
and upper extension
46
to enable toe protector
40
to surround edges
28
and
29
. Toe protector
40
is of course hollow to fit over toe cover
26
of pre-assembled upper
20
.
FIG. 7
illustrates the same sequence as
FIG. 5
but viewed from underneath. A layer of glue is also applied to marginal edge
34
. Toe protector
40
is slipped over the toe area of pre-assembled upper
20
and more specifically over toe cover
26
and the frontal part of insole
36
. Toe protector
40
is bonded to marginal edge
34
underneath pre-assembled upper
20
and is sometime glued to toe cover
26
. As shown in
FIG. 8
, once toe protector
40
has been positioned over toe cover
26
, mechanical pressure, depicted by arrows
51
, is applied on both sides of toe protector
40
to each lateral extension
48
. While the mechanical pressure
51
is applied, tabs
44
are tacked onto insole
26
through marginal edge
33
. This step results in lateral extensions
48
being tightly pressed against the exterior of each frontal edge
28
and
29
of pre-assembled upper
20
.
As shown in
FIGS. 9 and 10
, toe protector
40
is installed onto pre-assembled upper
20
in such a way that lateral extensions
48
overlap each frontal edge
28
and
29
. Since the entire pre-assembled upper
20
has been stretched to provide a proper form fit, toe protector
40
cannot be inserted between toe cover
26
and edges
28
and
29
. Cutout areas
43
of toe protector
40
are provided to surround frontal edges
28
and
29
and allow some degree of lateral motion to medial and lateral quarters
63
and
64
.
Finally, as shown in
FIG. 10
, an outsole
30
is nailed and glued to the bottom of pre-assembled upper
20
in order to complete the skate boot. It must be noted that the use of outsole
30
is optional since an ice blade holder or an in-line roller chassis having an integrated rigid platform conforming to the lower surface of upper
20
may be affixed to pre-assembled upper
20
rendering the outsole redundant. Outsole
30
is used when the blade holder or the in-line roller chassis requires a rigid platform for fastening.
FIG. 11
illustrates a finished skate boot
21
. The only step left to complete the skate is to mount an ice blade assembly or an in-line roller chassis assembly to outsole
30
by fastening it to the outsole
30
as shown in
FIGS. 12 and 13
. It should be noted that toe cover
26
further provides a more comfortable toe area for the skater. A normal skate boot does not have a textile cover in the toe region of the boot so the toes of the skater are directly in contact with the plastic toe cap.
The above description of preferred embodiments should not be interpreted in a limiting manner since other variations, modifications and refinements are possible within the spirit and scope of the present invention. The scope of the invention is defined in the appended claims and their equivalents.
