Abstract
A boot extension arrangement extends the upper boot portion of a skate to accommodate additional forward flex of the skater's lower leg about the ankle while maintaining or contributing to lateral stiffness. Two extenders are attached either side of the upper boot portion that oppose vertical buckling while allowing the boot to wrap around an open channel that accommodates bending movement of the user's lower leg about the ankle.
The ability to flex forwardly and provide lateral stiffness throughout the movement contributes to better skater performance.
The ability to flex forwardly and provide lateral stiffness throughout the movement contributes to better skater performance.
Description
TITLE: IMPROVED SKATE
FIELD OF THE INVENTION
The present invention relates to skates and in particular to improvements that allow increased leg flexion movement in the upper portion of the boot of the skate.
BACKGROUND OF THE INVENTION
My earlier US Patent 7,562,881 discloses a lace extension arrangement secured at the upper portion of a boot of a hockey skate that accommodates additional bending or flexion about the ankle in a forward/rearward direction. This increased flexion often provides improved performance for the user.
In my earlier design, lace extensions are provided at the upper edge of the hockey boot that allows the user to thread the lace through one of several forwardly extending eyelets appropriate to define a forward end position of the top opening of the hockey skate (flexion channel). The series of generally horizontal eyelets allow the user to determine the amount of bending or leg flexion that is accommodated. In my preferred embodiment, the two extension arms are joined by a U-shaped portion that extends behind the heel of the boot and the arms are secured by securing mechanisms that engage the top eyelets of the skate. Three forwardly extending eyelets are provided and the user can select which of these eyelets is best for his skating preferences.
The present invention also allows adjustment of the flexion channel and provides additional flexibility for the user to customize the installation of a combination boot and lace extender. The boot extender according to the invention allows the user to modify the characteristics of the skate and determine their own optimum or preferred position.
SUMMARY OF THE INVENTION
A boot extension arrangement according to the present invention is for use in association with the boot of a skate. The skate boot includes two opposed series of eyelets that cooperate with a tongue for adjustably closing the front portion of the skate using a lace. The boot extension arrangement comprises two extension portions located on opposite sides of an upper portion of the boot and cooperate to define an increased flexion channel therebetween to accommodate a user's leg when in a forward flex position. Each extension portion projects forwardly of a rearward-most eyelet of the series of eyelets for receiving laces at a position forward of a conventional securement position and has at least two vertically spaced apertures for selectively receiving a lace at the forward position.
According to an aspect of the invention the boot extension arrangement further includes two securement means located on opposite sides of the boot for securing the boot extension arrangements to the opposing series of eyelets. Each securement is comprised of a first securement aperture for mechanical securement of the boot extension arrangement through said top eyelet and a second securement aperture for securement to an eyelet below said top eyelet in said series of eyelets for receiving a lace.
According to yet a further aspect of the invention, the boot extension member is mechanically secured to the boot on an outside surface of the boot.

The boot has a securing set of two opposed series of eyelets for receiving a lace and securing the user's foot in the boot. A vertically spaced extension set of the two opposed series of eyelets are located on each extension portion of the boot. The top eyelet of the extension set of the two opposed series of eyelets is substantially forward of the rearmost eyelet of the securing set of the two opposed series of eyelets. In this way, the lace is passed through the eyelets, the user can utilize the series of eyelets on the extension portion of the boot to vary the length of the flexion channel.

In yet a further aspect of the invention, the securing set of two opposed series of eyelets is located across the bottom portion of the boot and extends to part way up the upper portion of the boot.
With the present invention the user can selectively alter the length of the flexion channel and can use the lace system to vary the length of the flexion channel to optimize his performance. Significant improvements in performance are typically realized with respect to faster skating, more powerful acceleration per push and enhanced agility and stability. This system allows a user to experiment with different setups to find a particular setup that provides him with the desired performance and confidence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows a side view of a hockey skate 2 having a boot 4 of the traditional type having a lower boot portion 6 and an upper boot portion 8. A tongue 10 is positioned within an opening of the skate and the skate is tightened about a user's foot using the two series of eyelets provided either side of the skate and tensioning the lace 12.
If the boot extension arrangement 20 was not present, two additional eyelets of the one series of eyelets would be visible at the upper portion of the upper boot. These eyelets are presently covered by the boot extension arrangement 20 which extends forwardly of the conventional securement position 19 of the lace and provides a series of forward eyelets 40 adjacent the front edge of the boot extension arrangement. These
- 5 -forward eyelets 40 as shown have three eyelets and the eyelets are vertically spaced. The vertical separation of these eyelets allows the user to select the number of eyelets he wishes to use to customize the flexion channel 30 defined between the Achilles tendon guard 60 and the tongue 10. The flexion channel 30 includes a length between the Achilles guard 60 and the tongue 10 indicated as 32.
With the boot extension arrangement as shown in Figure 1 a user can modify conventional skates to customize the length of the flexion channel 30 and this has been found to significantly impact the skating characteristics of the user. The boot extension arrangement is shown as mechanically secured to the upper two eyelets of the conventional series of eyelets of a hockey skate and each extension member at the forward portion 26 thereof includes the series of forward eyelets 40 where adjacent eyelets of the series are vertically spaced. The vertical separation allows the mouth of the flexion channel 30 to vary lowering a front edge thereof if desired. Also the eyelets can be used in combination.
As perhaps best shown in Figure 4 the boot extenders 22 are mechanically fastened to the upper boot 8 and extend the boot forward while still allowing inward curvature or deflection of boot narrowing and eventually determining a closed from of the flexion channel 30.
These extenders are not merely lace extenders as they cooperate and extend the upper boot portion and assist in providing lateral stability or stiffness.
For example, a user may choose to only use the bottom pair of eyelets, or the bottom pair in combination with the middle eyelets, or all three pairs of eyelets.
A user may also experiment using only the middle or upper eyelets. If the user only uses the lower pair of eyelets

For example, a user may choose to only use the bottom pair of eyelets, or the bottom pair in combination with the middle eyelets, or all three pairs of eyelets.
A user may also experiment using only the middle or upper eyelets. If the user only uses the lower pair of eyelets
- 6 -the length of the flexion channel 30 is generally lengthened and thus he can bend his leg farther forward before encountering the forward end of the flexion channel 30. It has been found that the upper portion 8 of the conventional hockey skate is quite stiff and provides excellent side to side rigidity and stability for the skater. The boot extension members 22 are also of a relatively stiff material (i.e. similar to that of the boot) and thus form an extension of the boot and do not readily bend towards each other but rather deflect towards each other under the influence of the lace as the boot would deflect. This arrangement generally keeps the flexion channel 30 open until restricted by the laces.
There is some deflection of the boot extension members towards each other at the forward edge and depending upon the tension applied to the laces, this adjustment is also variable by the user.
As perhaps best shown in Figure 4 the boot extenders 22 are mechanically fastened to the upper boot 8 and extend the boot forward while still allowing inward curvature or deflection of boot narrowing and eventually determining a closed front of the flexion channel 30.
These extenders are not merely lace extenders as they cooperate and extend the upper boot portion and assist in providing lateral stability or stiffness. The extending members 22 can be secured on the outside of the boot (fig. 1, 2 and 3) or on the inside surface of the upper portion of the boot (fig. 4).
The boot extension members preferably are of a plastic that can be heated to allow some bending or curvature and then cooled. This provides for further customization by a supplier or the end user. A preferred material for the boot extension members is supplied by Dupont under the mark Delrin 100 STTm.

- 7 -The particular placement of the eyelets in a conventional boot at the upper portion of the boot (i.e.
the top two or three eyelets) does vary from hockey skate to hockey skate. To accommodate this, the extension members 22 include at a rear edge of the extension member a single port, namely the upper port, for receiving a mechanical fastener 54 and a lower slot type aperture 55 for receiving a second mechanical fastener. In this way the slot 55 provides flexibility to accommodate the different spacing and positioning of the eyelets that is encountered from skate to skate. The slot is also helpful with respect to the angle of the upper eyelets.
The preferred length of the extension members 22 is approximately 1.5 inches and this provides a very significant modification of the flexion channel 30. We have also found that these extension members can be sold in a shorter length (i.e. approximately 1 inch) and this will provide approximately 15 degrees of additional flexion whereas the longer member provides approximately degrees of flexion forward. The distance between the top edge and the bottom edge of the boot extenders 22 is preferably about 1.25 to 1.5 inches. The extenders 22 when secured are stiff in the vertical direction 25 partially due to the overlapping and securement of the extenders to the upper portion 8 of the boot 4. The extenders are preferably about one eighth of an inch thick.
The rearward ports of the extension member provide firm securement of the member to the upper portion of the hockey boot and thus the extension members form extension portions of the boot and have similar type characteristics. The rear connection of the extenders to the upper portion of the boot fixes the extension members to the boot and extends the sides of the front of the boot preferably in excess of an inch. The extenders as

The rear connection of the extenders to the upper portion of the boot fixes the extension members to the boot and extends the sides of the front of the boot preferably in excess of an inch. The extenders as
- 8 -shown allow the extenders and upper portion of the boot to function as a continuous piece while still allowing curvature of the front portion of the upper portion of the boot using the lace arrangement. This integration allows the desired movement while providing lateral stability and user comfort (fit).
The two securement points avoid pivoting of the extension member and the series of forward eyelets provide for significant adjustment by the end user to accommodate different skates and experience the skate at different adjustment points. The user can determine a position that he finds both advantageous and acceptable.
As shown these members preferably extend the upper boot position along essentially the full side height and provide some lateral stability due to the significant top to bottom dimension of the extenders and the positive attachment at two or more points to function in the manner of the forward section of the upper boot. The thickness of the extenders is similar to the walls of the upper boot and are not prone to buckling or folding.
Movement of the extenders towards one another during lace tightening is transmitted back to the upper boot together with some deflection of the extenders.
The particular material of the extension members must react to relative cold conditions that may occur playing hockey outside, for example, as well as much warmer temperatures that are experienced in the later part of the season. The Delrin 100 STTm material is quite durable with respect to impact and will not crack during normal use. Other similar materials can be used. The materials used for existing stiff molded plastic hockey skates may also be suitable.

In a preferred embodiment, the extension arms are made to be integral with the hockey boot and can also be
- 9 -made such that the upper portion of the boot is of a different material than the lower boot portion. It is desirable that the particular type of plastic used can also be adjusted or modified by the end user by heating of the plastic by placing the extension member in boiling water and/or providing low heat such as by a hair dryer it is possible to bend the plastic, and the typical modifications are to bend it slightly inwardly providing a desired curvature, however it is also possible to deflect it in the vertical plane perhaps to open up the upper edge, for example. Once the member has been appropriately adjusted by the user, it is cooled and set and generally retains that shape unless it is reheated and adjusted again. As shown in the drawings it is not only lengthening the flexion channel but also providing the same type of lateral support to the user at different positions in the extended flexion channel. In contrast the lower boot portion and the lace system is primarily about securement and comfort.
Figure 3 shows a hockey boot with the two extension members applied or secured either side of the boot. It has been shown without the lace extending through the eyelets for clarity. The end user would select the appropriate eyelets he wishes to establish his particular length of the flexion channel and typically this is done merely by performance evaluation and/or comfort evaluation by the user.
In Figure 5, an extension measurement 100 is shown that is helpful in considering boot extenders to be used with a particular boot. The boot stock measurement 104 is the measurement from the heel to the vertical line that passes through the forward most extension point 106 where the user's shin is restrained by the laces.
Typically the 55 degree angle is a good base point. The boot stock measurement varies by the user. The extender

Typically the 55 degree angle is a good base point. The boot stock measurement varies by the user. The extender
- 10 -length is then determined by measuring from the top eyelet 102 to point 106. In most cases this is about 1 inch. The spaced vertical eyelets allow the user to adjust around this average setting to increase or decrease the extension.
Modern skates are now very stiff and if tied in the conventional manner the angle of flexion is restricted due to the stiffness of the boots. Even with a user applying considerable pressure against the tongue of the skate the amount of movement is restricted and not available without substantially opposition. The extenders 22 allow additional pivoting movement of the lower leg about the ankle in the forward and rearward direction while also contributing to lateral stiffness in the extended structure.
These extenders use the stiffness of the upper portion of the boot to allow the extenders to pull the sides of the upper portion inwardly (providing side support) while extending the amount of flex. This can be appreciated from a review of Figure 4. During skating a constantly changing dynamic movement and deflection of the upper portion of the boot can occur and the extenders in combination with the boot maintaining lateral stiffness throughout the flexion channel.
Building the extending members into a boot is advantageous as separate connection members (possible point of weakness) are not required and the product is more efficient, lighter and comfortable.
With the present system the extenders still allow variable wrapping of the extenders across the front of the flexion channel and distribute the user's leg force to a bigger area when restricted at the forward position.
This contributes to less shin issues such as shin bite

- 11 -and adjustment of the lace position can be helpful in addressing any pressure points. The extenders extend the sides of the upper portion of the boot such that the conventional functions and desirable characteristics of the upper portion of the boot can be maintained and improved.
It has been found that skate performance can be improved such as increased stride length, more power, expanded mobility, enhanced ankle flexion, greater knee bend and/or better balance. Figure 4 shows the lower legs of a user with two skates and the extent that one leg is significantly bent while the other one is more vertical. These positions are constantly changing during skating.
The present invention provides a simple and effective approach for allowing a user to modify a conventional stiff skate (such as a hockey skate) or to modify the structure of a conventional stiff skate boot in a new manner that is integrated with the upper portion of the boot to provide a greater flexion channel and lateral support relative to the non-modified skate. This approach of extending the upper portion of a stiff skate boot is also useful in figure skates, speed skates and inline skates. The hockey skate boot application is believed to be the most demanding and difficult application.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the appended claims.
