Abstract
A tongue construction for footwear is configured with a tongue and a stiffener that is able to move relative to the tongue, thereby resisting pinching of the rider's foot as the boot is flexed. As a result, footwear having desired stiffness while substantially reducing discomfort, especially during flexing of the footwear is provided. By allowing the stiffener to slide rather than bend, or at least to reduce the extent of bending of the stiffener, pinching of the dorsal area near the ankle may be minimized as may be digging of the stiffener into the dorsal area near the toe. Consequently, a soft or hybrid snowboard boot is provided that provides both enhanced power transmission as well as improved wearer comfort.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to footwear, and more particularly to a tongue stiffener for footwear.




2. Related Art




Snowboard boots provide a rider with a selected combination of flexibility and support for comfort and board response. Snowboard boots also provide the rider with good “feel” or feedback from the board as it traverses terrain to allow for improved board control in a variety of conditions.




Board control may be affected by the stiffness of the boot. With increased stiffness, such as provided with hard boots, comes increased force transmission and greater board control. However, hard boots may be uncomfortable, especially while walking. On the other hand, flexible boots (soft and hybrid boots) may be less responsive to rider induced forces but are more comfortable. Hybrid boots include features of both soft and hard boots. In this respect, hybrid boots may include a rigid or semi-rigid sole and an upper portion divided into a rigid or semi-rigid lower portion and a flexible top portion.




Boots are known which attempt to balance the comfort of a soft or hybrid boot with the force transmission of a hard boot. These soft or hybrid boots may include a tongue configured with a rigid member or stiffener for imparting stiffness and resulting power transmission particularly on toe-side turns. Such tongue constructions, however, may create pressure points on a user's foot or leg when the boot is flexed. In this respect, as a rider leans against the top portion of the boot tongue during a toe-side maneuver, the stiffener may bend at the mid-section, which may pinch the dorsal area of the rider's foot near the ankle. In addition, flexing of the tongue may cause the front end of the tongue stiffener to dig into the dorsal area of the rider's foot near the toe.




SUMMARY OF THE INVENTION




The present invention is directed to a tongue stiffener and to a tongue including a tongue stiffener (hereinafter referred to as tongue constructions) that provide enhanced footwear stiffness. The tongue stiffener may be adapted to conform to the shape of the footwear tongue and is configured for movement relative to the tongue as the footwear is flexed forwardly. By allowing the stiffener to move in a controlled manner pinching of the dorsal area near the ankle may be minimized as may be digging of the stiffener into the dorsal area near the toe or shin. Pinching by the stiffener may further be controlled by forming flex inducing members along at least a portion of the sides of the stiffener. Consequently, footwear including the inventive tongue stiffener arrangement provides both repeatable enhanced power transmission as well as improved wearer comfort. In addition, the stiffener may include apertures for receiving stiffness adjusters for varying the flexibility of the stiffener.




In one illustrative embodiment of the invention, a tongue construction for an article of footwear includes a tongue and a tongue stiffener. The tongue stiffener includes an elongated body having a first portion engaged to the tongue and a second portion movable relative to the tongue as the tongue is flexed forwardly. Movement of the second portion thereby reduces pressing of the stiffener into the tongue.




Various embodiments of the present invention provide certain advantages. Not all embodiments of the invention share the same advantages and those that do may not share them under all circumstances. This being said, the present invention provides numerous advantages including the noted advantage of providing repeatable increased stiffness to a soft or hybrid boot while reducing discomfort during flexing of the boot.




Further features and advantages of the present invention, as well as the structure and operation of various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

DETAILED DESCRIPTION





FIGS. 1-3

show a tongue stiffener


24


according to one illustrative embodiment of the invention. The tongue stiffener


24


is constructed and arranged to cooperate with a tongue


22


of an article of footwear, such as a boot


20


. The stiffener is engaged with the tongue in a manner to allow movement relative to the tongue


22


, at least along a shin-to-toe direction. In one embodiment, the stiffener


24


is attached to the shin portion of the tongue


22


(hereafter referred to as the upper end


30


) but includes a limited region of unconstrained movement at the toe region of the tongue


22


(hereafter referred to as the lower end


32


). Thus, an upper end


34


of the stiffener


24


is attached to an upper end


30


of the tongue


22


and a lower end


36


of the stiffener


24


is not attached to the lower end


32


of the tongue


22


. Therefore, as the boot is flexed in a direction shown as arrow A in

FIGS. 2 and 3

, the lower end


36


of the stiffener


24


is free to move, such as by sliding, in a direction shown by arrow B, relative to and over, or along the surface of, the tongue


22


. Movement of the stiffener


24


as the tongue


22


(or boot) is flexed reduces the likelihood of discomfort to the rider; in this respect, pinching of the dorsal area of the rider's foot near the ankle by the mid-section of the stiffener as well as digging into the dorsal area near the rider's toe by the leading end of the stiffener may be minimized. Although the stiffener


24


moves relative to the tongue


22


, it nevertheless cooperates with the tongue


22


to provide a stiffer tongue construction through which to transmit rider induced forces particularly on toe side turns as compared to the same tongue but having no stiffener.




Flexing in the medial or lateral direction also may be provided by allowing the stiffener


24


to move in a sideways, or partially sideways direction, relative to the tongue


22


. In this respect, as the rider rolls his foot outwardly (laterally) or inwardly (medially), the stiffener


24


may shift over the tongue


22


. If the stiffener


24


was otherwise constrained, the stiffened tongue


22


would resist medial or lateral flexing, thereby potentially limiting the performance and comfort of the boot.




In the embodiments described herein, the tongue stiffener overlies an outward facing surface


37


of the tongue


22


. However, it is to be appreciated that the present invention is not limited in this respect and that other suitable locations may be utilized. For example, the tongue stiffener


24


may be mounted within the tongue or may underlie the tongue


22


on an inward facing surface


38


of the tongue


22


.




The stiffener


24


may be permanently or removably attached to the tongue


22


. In one illustrative embodiment, as shown in

FIGS. 1-3

, a hook


50


, which may be attached to the upper end


30


of the tongue


22


, may be used. The stiffener


24


may include a slot


52


which is adapted to engage with the hook


50


. As best shown in

FIGS. 4 and 5

, the tongue


22


may be formed with an opening


53


at the upper end


30


thereof to receive the hook


50


therein. Of course, the present, invention is not limited in this respect and the hook


50


may be attached to tongue


22


by any suitable arrangement. Other, suitable attachment techniques may be employed, such as screws, rivets, hook and loop fasteners, stitches, pockets, straps, adhesives, clamps, etc. A pocket may be formed either within the tongue body itself or by simply stitching a cover over the surface of the tongue. The tongue stiffener may also be configured with grooves that fit into corresponding guides in the tongue. The tongue stiffener may be fixed to the tongue to provide a controlled movement of the stiffener in a shin-to-toe direction relative to the tongue upon flexing. In this respect, each time the tongue is flexed, the tongue stiffener may be able to return to its original position. Thus, whenever subsequent flexing occurs, a similar performance of the boot may be provided.




Although the stiffener


24


is shown as fixed at the upper end


30


of the tongue


22


, it is to be appreciated that the present invention is not limited in this respect and that other suitable fixing locations may be provided so long as at least a portion of the stiffener


24


is capable of moving relative to the tongue


22


as the tongue or footwear is flexed. For example, the stiffener


24


may be fixed at an intermediate point, such as along one or both sides, with free upper and lower ends. Alternatively, the stiffener


24


may be fixed at the lower end with a free upper end. Other suitable locations or combination of locations will be apparent to one of skill in the art. It is to be appreciated, however, that fixing a portion of the tongue stiffener at a particular location should allow the other portions of the tongue stiffener to move relative to the tongue so as to prevent pressing of the tongue stiffener against any portion of the wearer's foot and/or leg.




Continuing with reference to

FIGS. 2 and 3

, the tongue stiffener


24


may be shorter than the tongue. In this respect, the lower end of the tongue stiffener is spaced from the lower edge of the tongue and the upper end of the tongue stiffener is spaced from the upper edge of the tongue. In one embodiment the tongue


22


may be formed with a recess


40


configured to receive the tongue stiffener


24


. The recess


40


may be longer than the tongue stiffener


24


, thereby defining an open area


42


between the lower end


36


of the stiffener


24


and a lower edge


44


of the recess


40


. The open area


42


provides a path for the tongue stiffener


24


to move in the recess


40


upon flexing of the boot. The open area


42


should be long enough to allow the stiffener to slide through a predetermined angle of flex of the footwear. For example, the recess


40


may be configured to allow the footwear to be flexed up to an angle of 45° from its rest position, without the end of the stiffener abutting the end of the recess. In one embodiment, the recess


40


is about 2 cm longer than the tongue stiffener


22


, although more or less distance may be provided. Although the recess


40


is longer than the tongue stiffener


24


, it should be appreciated that the present invention is not limited in this respect and that the recess


40


may be made substantially the same size as the tongue stiffener


24


, where the tongue stiffener


24


is not intended-to move appreciably relative to the tongue


22


.




In the embodiments where the bottom end of the tongue stiffener is fixed to the bottom end of the tongue, an open area may be formed at the top of the recess in which the tongue stiffener may move when the boot is flexed forwardly. The extent to which the tongue stiffener moves may be limited so as not to press into the rider's leg. The length of the stiffener may be less than the length of the tongue to ensure that, upon flexing, the tongue stiffener does not extend beyond the upper end of the tongue.




Similarly, in embodiments where the tongue stiffener is fixed at an intermediate location, the recess may be configured to provide an open area at an upper end, at a lower end or at both the upper and lower ends. Also, if no recess is provided, the ends of the stiffener should be spaced from the corresponding ends of the tongue.




The recess


40


formed in the tongue


22


may also allow the tongue


22


and tongue stiffener


24


to form a slender profile. In one embodiment, the recess has a depth about equal to the thickness of the tongue stiffener such that presence of the stiffener


24


does not create a pressure point against the wearer's foot or leg. For example, the boot may be configured with closure devices, such as laces, straps, cables, cords, and other devices recognized by those of skill in the art, that extend across the tongue of the boot. Tightening of the closure devices may cause a downward force on the tongue that can be distributed over both the surface of the tongue as well as the stiffener, rather than just over the stiffener, because, in this embodiment, the stiffener does not protrude beyond the profile of the tongue. Rather, the stiffener is disposed within the recess. If the stiffener was to protrude beyond the surface of the tongue, (i.e., not received within the recess), then the force of the closure devices would act only on the stiffener, potentially causing an uncomfortable pressure point. It should be appreciated that such a downward force on the tongue and stiffener may not only arise from tightening a wearer's foot within the boot, but also may arise when securing the boot to a strap binding for a snowboard where the strap extends across the front of the boot, as is the case with convention tray bindings for snowboards.




Of course, it should be appreciated that the present invention is not limited in this respect and that a recess need not be provided or may be deeper or shallower, as desired, with a desirable, although not required, corresponding change in the thickness of the tongue stiffener.




To aid in maintaining the stiffener


24


adjacent the tongue


22


while allowing for relative movement between the two, a cover


45


may be stitched or otherwise joined to the tongue


22


. The cover


45


may also function to loosely constrain or to limit shin-to-toe movement and medial and/or lateral movement of the stiffener


24


. The cover


45


may be formed of leather or a synthetic fabric or other suitable material that is durable yet sufficiently resilient to allow controlled flexing or movement of the stiffener


24


. Although a cover


45


is illustrated, other arrangements for maintaining the tongue stiffener


24


adjacent the tongue


22


may be utilized. The cover may also loosely constrain shin-to-toe movement while restricting medial and/or lateral movement of the stiffener


24


. Alternatively, the cover may restrict movement of the tongue stiffener in the shin-to-toe direction but may loosely constrain medial and/or lateral movement of the stiffener. In addition, such an arrangement may be configured to loosely hold the tongue stiffener adjacent the tongue such that limited movement of the tongue stiffener away from the surface of the tongue may be provided.




One such arrangement includes harnessing the stiffener


24


with a band extending across at least the lower end


36


of the stiffener


24


or with the laces of the boot as the laces are tightened. The width of the band may be sufficient to extend a substantial portion of the length of the stiffener. Another such arrangement includes providing the tongue


22


and stiffener


24


with a post and mating slot to receive the post. The post is able to slide within the slot to allow relative movement of the stiffener and the tongue. Another arrangement includes forming a pocket in the tongue


22


so that at least the lower end


36


of the stiffener


24


may be held therewithin. Other suitable arrangements will be apparent to one of skill in the art. In addition, it is to be appreciated that no such arrangement is necessary for the stiffener


22


to function according to the invention.




Referring now in particular to

FIG. 3

, which is a cross-sectional view of the tongue


22


taken along line


3





3


of

FIG. 2

, in one illustrative embodiment, the lower end


36


of the stiffener


24


may be formed with a tip


46


having a tapered, stepped or other suitably narrowing dimensioned cross-section. In one embodiment, the tip narrows from a thickness of about 2 mm to a thickness of about 1 mm. This narrowing dimensioned tip


46


facilitates movement of the stiffener


24


relative to the tongue


22


, thereby allowing the stiffener


24


to easily glide over the tongue


22


and reducing the likelihood of the stiffener


24


catching on the surface of the tongue


22


. In addition, the width of the lower end of the tongue stiffener may taper toward the tip. Such tapering may be suitable to further facilitate movement of the stiffener relative to the tongue. This tapering may also facilitate insertion of the stiffener beneath the cover or into another suitably configured arrangement to hold the lower end of the stiffener adjacent the tongue. Further, the surfaces of the stiffener may be lightly textured so as to permit ease of movement relative to the tongue and other components of the footwear.




Continuing with the illustrative embodiment of

FIGS. 4 and 5

, the hook


50


may include a base


54


, having an inwardly facing side


55


, and an insert


56


. The insert


56


may include an annular region


58


that snap fits into the opening


52


of the stiffener


24


to hold the stiffener relative to the tongue


22


at the upper end


30


thereof. The base


54


of the hook


50


may be received in a depression


60


formed on the inwardly facing surface


38


of the tongue


22


so that the hook


50


does not protrude into the area of the boot occupied by the wearer's shin. In this respect, the hook


50


does not interfere with the comfort of the tongue


22


against the wearer's shin. To enhance the comfort, a foam covering


61


may be glued or otherwise attached over the inwardly facing side


55


of the base


54


. However, it should be appreciated that the present invention is not limited in this respect and that the neither the depression


60


nor the covering


61


is required.




The base


54


of the hook


50


may include a bore


62


to receive the insert


56


and may be attached to the insert


56


with the use of a rivet


70


, or any other suitable fastener. An axially extending groove or ridge


74


may be formed on the insert


56


to engage with a corresponding mating feature


75


on the base


54


to reduce the possibility of relative rotation. It is to be appreciated, however, that other suitable anti-rotation features may be used. The hook


50


may also be used to receive the laces of the boot to maintain the tongue


22


in a relatively central position with respect to the boot.




In an alternative embodiment, as shown in

FIG. 6

, the insert


56


may have an annular ring


78


to snap fit into a corresponding groove


80


formed in the base


54


, thereby obviating the need for the rivet or other fastener. Although not shown, this embodiment may also include a suitable anti-rotation feature to reduce the possibility of rotation of the hook


50


.




As described above, the present invention is not limited to any particular attachment mechanism to secure the stiffener


24


to the tongue


22


and other suitable arrangements may be used. In this respect, referring in particular to

FIG. 7

, an alternative embodiment for attaching the stiffener


24


to the tongue


22


is shown. In this illustrative embodiment, the upper end


34


of the stiffener


24


may include one or more eyelets


90


for receiving the lace of the boot. The tongue


22


may also be formed with one or more corresponding eyelets


92


. Thus, the lace may be used to secure the upper end


34


of the stiffener


24


to the tongue


22


, while centering the tongue


22


relative to the boot.




The tongue stiffener


24


as shown in

FIG. 1

, may be conformable to approximate the contour of the tongue or be sufficiently flexible to conform to the surface of the tongue as the tongue stiffener is drawn to the surface of the tongue by, for example, the closure device of the boot or the straps of the binding. In this embodiment, the stiffener body includes a medial side


39




a


and a lateral side


39




b,


each extending between the upper end


34


and the lower ends


36


. The stiffener body may be formed with a concave top surface in a direction that extends from the upper end


34


to the lower end


36


and may also include a convex top surface in a direction that extends from the medial side


39




a


to the lateral side


39




b.


The surface of the stiffener that conforms to the contour of the tongue preferably includes a smooth surface having limited projections extending therefrom which would otherwise interfere with the surface of the tongue upon sliding of the stiffener relative to the tongue. In addition, the surface that approximates the shape of the tongue also includes a complementary shaped surface to that of the top surface. Namely, the bottom surface is convex in a direction that extends from the upper end


34


to the lower end


36


and includes a concave surface in a direction that extends from the medial side


39




a


to the lateral side


39




b.






The sides


39




a,




39




b


may taper toward each other at the mid-section of the stiffener such that the resulting shape resembles an hour-glass. This reduced width at the mid-section also allows a change in the stiffness of certain portions of the stiffener relative to other portions. In this respect, the stiffener may easily bend about the mid-section. The tapered sides, and resulting hour-glass shape, also limits the amount of material at the mid-section so that, as the tongue is flexed forward, the sides may remain substantially in contact with the tongue surface, thereby minimizing bulging of the stiffener. However, the present invention is not limited in this respect and that other suitable methods for causing the sides to remain in contact with the tongue may be employed. In this regard, the stiffener may be formed with straight sides, each having a laterally extending slit formed therein at generally the midsection of the stiffener. Thus, as the tongue and stiffener is flexed forward, the sidewalls separate at the slit, thereby causing the sides to substantially remain in contact with the tongue surface and minimizing bulging of the stiffener. In another example, the sides of the stiffener may be formed with a relatively elastic material so as to conform to the resulting shape of the flexed tongue.




In one illustrative embodiment, the width of the tongue stiffener is less than the width of the tongue and also may be less than about the distance between eye stays


120




a


and


120




b


(see

FIG. 1

) of a boot when in the secured position. In one embodiment, the width of the tongue stiffener is preferably less than 3 inches, more preferably less than 2.5 inches, and even more preferably less than about 2.25 inches. The width of the tongue may be about 7 inches. The length of the tongue stiffener may be less than about 7 inches, and more preferably less than about 6 inches, and the length of the tongue may be about 10 inches.




In some instances, it may be desirable to control the flexibility of the tongue


22


and subsequently the boot and this flexibility may be controlled in a number of ways. The stiffener


24


may be removable from the tongue


22


allowing the rider to choose between a more stiff boot (with the stiffener


24


attached) and a more flexible boot (with the stiffener


24


removed). The boot may be also be provided with interchangeable stiffeners


24


, each having a different flexibility. Thus, the wearer may select from a variety of stiffeners to alter the properties of the boot. The flexibility or rigidity of the stiffeners


24


themselves may be varied in any of a number of ways; for example, by forming the stiffeners with different materials or by forming the stiffeners with different shapes or dimensions. In one illustrative embodiment, a stiffener


24


may be formed of a semi-rigid material such as thermal plastic polyester elastomer so that it is stiffer than the tongue. In one embodiment, the tongue stiffener may have a durometer of about 74 Shore D and the tongue may have a durometer of between about 55 and about 58 Asker C. Of course, the tongue and tongue stiffener may be configured with other suitable hardnesses.




One example of suitable material forming the tongue stiffener, such as a thermal plastic polyester elastomer, is Hytrel®, which may be purchased from the E. I. du Pont de Nemours and Company, USA. Other suitable plastics, such as thermoplastic polyurethane or nylon, may be used for this or other stiffeners. Also, non-plastic materials may be used. The stiffener may also be formed of two or more materials, each material having a different stiffness. Each material may be formed at a discrete location on the stiffener body, thereby causing the stiffener body to have a varied stiffness.




As mentioned, the flexibility or rigidity of the stiffener


24


also may be adjusted by providing the stiffeners with different shapes. For example, controlling the dimensions of the hour-glass shape may aid in providing the stiffener with a desired stiffness. In addition, one or both sides


39




a,




39




b


may include a plurality of flex inducing members such as grooves or notches


98


having a bottom and a sidewall. The grooves


98


may be sized and shaped to provide a desired rigidity or stiffness at least to a portion of the stiffener, such as the midsection. In this respect, due in part to the presence of the grooves, the mid-section is able to flex to a greater extent than other portions of the stiffener. The grooves


98


may also act to minimize kinking of the mid-section of the stiffener as the tongue and stiffener are flexed. In this respect, the grooves


98


provide controlled flexing of the stiffener.




In addition, at least one aperture


100


may be formed completely through the stiffener


24


, with the aperture


100


being shaped and dimensioned in accordance with the desired flexibility or rigidity Like the grooves


98


, the apertures


100


may also act to minimize kinking of the stiffener as the tongue and stiffener are flexed. The flexibility or rigidity of a single stiffener


24


may be further adjusted by providing a stiffness adjuster


102


, which may fit into the aperture


100


, or any other suitable aperture formed in the stiffener. Of course, the stiffness adjuster


102


need not be placed into an aperture of the stiffener, but rather may be attached to one or more locations on the surface or periphery of the stiffener body. A variety of inserts may be supplied, each rendering the stiffener


24


with a different degree of stiffness. The stiffness adjuster may be formed of an elastomer or any other suitable material. Accordingly, a wearer may adjust the flexibility by selecting a desired type or number of stiffness adjusters


102


.




The various embodiments of the tongue stiffener described may be used with any suitable footwear cooperating with a tongue. In one example, as shown in

FIG. 1

, a soft or hybrid snowboard boot


20


the tongue


22


is attached to the boot upper


26


, which extends from a flexible sole


28


, near a toe area of the boot upper


26


. The tongue may be a molded tongue or a stitched tongue. A fabric may be stretched over the tongue. The tongue may be joined to the upper by stitching, bonding or other suitable joining arrangements as would be apparent to one of skill in the art. The upper is formed of a suitable material, such as leather. To provide traction on snow covered terrain, the sole


28


may be formed with treads. The sole


28


may also include a foam inner sole or midsole to dampen shock transmission to the rider's feet induced during various maneuvers, such as landing jumps. An inner bladder or boot liner, whether permanent or removable, may also be provided for a snug fit and insulation from cold temperatures, snow and water. The boot may be constructed with any suitable closure device, such as buckles, laces, rotary closure systems and the like. Although the tongue


22


is shown attached to the boot upper


26


, it should be appreciated that the present invention is not limited in this respect. Instead, the upper


26


may be formed without a tongue, and the tongue may be part of the inner bladder. In addition, the tongue


22


may be a free-floating tongue.




For ease of understanding, and without limiting the scope of the invention, the tongue stiffener for footwear to which this patent is addressed is discussed below particularly in connection with a snowboard boot. However, it should be appreciated that the present invention is not limited in this respect, and that the aspects of the present invention described below can be used in association with other types of footwear.




Having thus described certain embodiments of the present invention, various alterations, modification and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description is by way of example only, and not intended to be limiting. The invention is limited only as defined in the following claims and the equivalent thereof.
