BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to footwear, and, more particularly, to a closure system which allows an article of footwear to be conveniently and adaptively attached to the foot.
2. Description of Related Art
Shoe and boot designs, driven by various combinations of fashion and function, have been evolving for centuries. Many varieties of styles have proven to be viable in the market place. Specialized features such as sole tread design, upper height and material, lacing schemes and interior last shapes have allowed function to reflect targeted uses.
Since an article of footwear must integrate with the three-dimensional shape and surface features of the human foot, a variety of closure systems have been devised. These include laces, straps, elastic panels, buckles, etc. In concept, these systems are designed to allow the wearer to close or tighten the shoe's upper around the foot and secure the article in place for walking, running of whatever other activity is desired. Some footwear designs have made use of relatively rigid panels or component members such that foot and ankle support is increased when the closure system is adjusted for a given foot shape. These “hard” panels are normally shaped and positioned to allow the foot convenient entry to the interior of the shoe, then are brought closer to the foot's external shape as the closure system is tightened. Thus, the rigid panels, by themselves, are made functional only by the positioning and security that laces, stretchable elements or other closure systems provide.

SUMMARY OF THE INVENTION

Disclosed is a footwear closure and fit system in which one or more firm but flexible fitting members, such as fit panels, are integrated into the construction of an article of footwear, such as a shoe or boot. These panels are configured so as to hold the article of footwear to the foot without the use of laces, straps or other attachment devices. The panels are designed and positioned such that in a default or relaxed state, they define an interior space somewhat smaller in volume than the user's foot. To enter the shoe or boot, the fitting panels are retracted, either manually or simply by the motion of the foot entering the interior space. As the foot becomes located in it's proper position within the shoe or boot, the flexural force of the panels exerts a closing force against the foot, with an equilibrium attained that allows the shoe or boot to effectively become one with the foot. Advantageously, the fit panels do not require manual or mechanical tightening by the user to effect their closure function, although the closure and fit system may be supplemented with manual attachments, such as, for example, laces or clips.
The flexible panels may either bear directly onto the foot surface, or be enclosed within the body of the shoe or boot's upper thus activating an intermediate layer for the purpose or positioning the foot as desired. It is also foreseen that primary flexural panels could bear upon other attached but articulating secondary panels, whereby the flexural force of the primary panels holds the articulating secondary panels against the foot. The articulating secondary panels then may more freely adapt to the contours of the individual foot. The panels, in their variety of arrangements, may be incorporated into any type of footwear, including shoes, boots, and sandals.
Other features and advantages of the present invention should be apparent from the following description of the preferred embodiment, which illustrates, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Throughout this description, the preferred embodiment and examples shown should be considered as exemplars, rather than limitations on the apparatus and methods of the present invention.
As shown in the above-described figures, the invention is footwear 5 that includes a footwear member 10 and a footwear fit system 28 that is operably attached to a footwear member 10. The footwear member 10 includes a sole 12 that includes a top sole surface 14, a bottom sole surface 16, a first side 18, a second side 20, a rear side 22, and a front side 24. The footwear member 10 can also include various additional elements, such as an upper 25 and an inner lining 27, as described in greater detail below. The footwear fit system 28 can include one or more fitting members 30, a heel portion 70, a tongue element 70, and/or a front fitting member 95. The one or more fitting members 30 and/or the other elements described function, in combination, to removably attach the sole 12 to a foot 26 of a user, and are described in greater detail below.
Various embodiments of this invention are described, in turn, below. Before describing these particular embodiments, however, we will first discuss the general structure and function of the invention.
In the embodiments shown in FIGS. 1A-7 and 9, the footwear member 10 is a form of sandal. In the embodiment shown in FIG. 8, the footwear member 10 is a boot. As shown in FIG. 10, the footwear member 10 can also be a casual shoe. It is appreciated that the footwear fit system 28 could be incorporated into any type of footwear member 10, including sports shoes, dress shoes, women's shoes, loafers, or other form of shoes, boots, or other footwear. The scope of the claimed invention should be construed to include all manner of footwear, and should not be limited to the specific embodiments described herein.
As shown in FIG. 1B, the footwear fit system 28 is configured to fit snugly around the foot 26 and thereby secure the foot 26 on the top sole surface 14 and within the footwear member 10 (if the footwear member 10 includes an upper 25). As shown in FIGS. 1A-15, the footwear fit system 28 includes one or more fitting members 30, described in greater detail below, that extend upwardly from the sole 12. The fitting members 30 and the sole 12 collectively define a volume 32 that is sized to receive the foot 26. The fitting members 30 preferably also define an entryway 34 that opens into the volume 32. The sole 12 is positioned beneath the foot 26 when it positioned within the volume 32.
The fitting members 30 extend upwardly from the outer periphery of the sole 12 and are disposed around the foot 26 when the foot 26 is located within the volume 32. As shown in the cross-sectional view of FIGS. 3B, 5, 7, and 11A-11E, the fitting members 30 preferably have a thin cross-sectional shape and are preferably contoured such that an interior surface of the fitting members 30 conform to the outer contour of the foot 26 when in use. The fitting members 30 may include a padded layer 36 for added comfort, or may be unpadded, and may also be of varying widths and thicknesses so as to define closure characteristics and areas of high versus low pressure against the foot 26.
With reference still to FIGS. 3B and 5, the fitting members 30 are preferably biased toward a default position (shown in solid lines) such that in an undisturbed state, the volume 32 is smaller than the volume of the foot 26. In this manner, the fitting members 30 preferably exert pressure against the foot 26 when the foot 26 is disposed within the volume 32 and thereby secure the foot 26 to the sole 12. The bias in the fitting members 30 toward the default position is accomplished by fabricating the fitting members using materials with specific characteristics and to a specific shape. The material preferably has a flexural modulus that allows the member to be elastically deformed outward as the foot 26 is inserted into the volume 32, while being able to elastically return toward the default position once the foot 26 is in place within the volume 32. The material will preferably have little or no hysteresis and will also not be subject to changes in it's flexural modulus (weakening or permanently being deformed) over time. The shape of the members is also preferably designed to exert more or less continuous pressure against the surface of the foot 26. The attachment point for each member is preferably of a rigid nature, connected either to a substantial portion of the shoe's sole 12 or continuing under or through the shoe to the fitting member(s) on the opposite side. This firm attachment provides that substantially all of the elastic travel inherent in the member's design is achieved through the flexural deformation of the material itself, rather than through the use of a mechanical hinge or other mechanism.
The fitting members 30 are preferably configured to allow movement to an extended position (shown in phantom lines) such that when in the extended position, the volume 32 increases in size. The size of the entryway 34 also increases when the fitting members 30 are moved to the extended position. The entryway 34 preferably increases to a size such that the foot 26 may be inserted into the volume 32 by sliding the foot 26 at least partially through the entryway 34.
It will be appreciated that the particular size, shape and location of each of the fitting members 30 could be varied to change the size and shape of the volume 32. The fitting members 30 preferably have a shape such that the volume 32 approximates the shape of the foot 26. The fitting members 30 are preferably rigid such that the fitting members maintain their general shape and do not plastically deform when pressure is applied thereto. However, the fitting members 30 are also flexible so that the fitting members 30 conform to the shape of the foot 26 when the fitting members 30 bear against the foot 26. The outline shape of the fitting members 30 is not necessarily elastic or stretchable. However, the range of movement of the fitting members 30 between the default and the extended position is preferably configured such that the fitting members 30 automatically recover to the default position after being moved away from the default position. The position of the fitting members, as they define the default position, may additionally be adjustable by either the manufacturer, retailer or user.
The fitting members 30 may be manufactured of any of a wide variety of materials to vary the characteristics of the fitting members 30, such as the flexibility and hardness. In one embodiment, the fitting members 30 are manufactured of injection molded nylon. Select regions of the fitting members 30 may also be manufactured of a different material than other regions of the fitting members, or of varying structural thicknesses, such as to vary the flexibility of the fitting members 30 within the select regions.
A fabric loop (not shown) or other gripping surface may be installed at the top of the fitting members 30 to facilitate entry of the foot 26. Alternatively, a tongue element 90, described in greater detail below, may be installed between the fitting members 30 and the foot 26 which, when manually retracted, facilitates entry. Alternatively, an elastic inner lining 27 may exist between the foot 26 and the fitting members 30 to help position the foot 26 with respect to the sole 12, with the fitting members 30 providing additional security of fit. These alternative embodiments are described in greater detail below.

First Embodiment

In a first embodiment, as shown in FIGS. 1A and 1B, the footwear fit system 28 includes a pair of side fitting members 40 that are disposed around the medial and lateral regions of the foot 26 when the foot 26 is positioned within the volume 32. The side fitting members 40 preferably have an arc-like shape that is selected to resemble the shape of the foot 26. The side fitting members 40 act to secure the instep and forefoot areas of the foot 26.
As illustrated by this embodiment, the pair of side fitting members 40 include a first base portion 42 that extends upwardly from the first side 18 of the sole 12, and a second base portion 48 that extends upwardly from the second side 20 of the sole 12. A first foot-bearing portion 44 extends laterally from the first base portion 42 to a first terminus 46. The first base portion 42 and the first foot-bearing portion 44 together form at least one resilient elongate finger that independently biases the first foot-bearing portion 44 towards the sole 12.
A second foot-bearing portion 50 extends laterally from the second base portion 48 to a second terminus 52. The second base portion 48 and the second foot-bearing portion 50 together forming at least one resilient elongate finger that independently biases the second foot-bearing portion 50 towards the sole 12. The first terminus 46 is positioned adjacent to the second terminus 52. For purposes of this specification, the first terminus 46 should be considered as positioned adjacent the second terminus 52 as long as they are generally close to each other and together function to fasten the footwear member 10 to the sole 12. As illustrated below, the first terminus 46 and the second terminus 52 can be located in a variety of positions, as long as this functional relationship is maintained. In this embodiment, the side fitting members 30 are sized such that the fingers extend toward the median line of the foot 26, but the first terminus 46 does not overlap the second terminus 52.
Illustrated in FIG. 1A, the first base portion 42 further includes a first foundation member 54 that extends inwardly from the first base portion 42 into or overlapping sole 12; and the second base portion 48 includes a second foundation member 56 that extends inwardly from the second base portion 48 into or overlapping the sole 12. The first and second foundation members 54 and 56 function to provide a strong foundation for the first and second base portions 42 and 48 so that they can most effectively bear down on the foot 26 and hold the footwear member 10 in its proper place. One particular benefit of this construction is that the full weight of the user bears down on the first and second base portions 42 and 48 when the user stands on the footwear member 10, thereby providing an especially strong hold on the foot 26 of the user.

Second Embodiment

In a second embodiment, as shown in FIGS. 2A and 2B, the pair of side fitting members 40 are fundamentally the same as the first embodiment, but are constructed so that the first terminus 46 and the second terminus 52 overlap. By designing the pair of side fitting members 40 so that the first terminus 46 and the second terminus 52 overlap, the pair of side fitting members 40 can exert more gripping power against the foot 26. The first terminus 46 and the second terminus 52 are still considered adjacent to each other, as defined in the present invention, despite the fact that they overlap.

Third Embodiment

The third embodiment of the footwear fit system 28, as shown in FIGS. 3A and 3B, also includes a rear fitting member 66 that extends upwardly from the rear side 22 of the sole 12. The rear fitting member 66 preferably has a shape that conforms to the rear or heel region of the foot 26. The rear fitting member 66 preferably bears against the calcaneous area of the foot 26 and applies pressure against the foot 26. Preferably, the rear fitting member 66 may be moved in a forwardly or rearwardly direction with respect to the foot 26. The rear fitting member 66 is biased toward a default position (shown in solid lines in FIG. 3B). The rear fitting member 66 may be moved rearwardly toward an extended position that increases the size of the volume 32 and the size of the entryway 34. In one embodiment, the rear fitting member 66 has a range of travel of approximately 15 mm in forwardly and rearwardly direction. The rear fitting member 66 preferably pivots at a location near where the rear fitting member 66 is attached to the sole 12. The footwear fit system 28 may be configured so as to function with or without the rear fitting member 66.
The fitting members 30 may be integrally attached to the sole 12. Alternately, the fitting members 30 may be attachable and/or adjustable by the user, thereby allowing the user to position the fitting members 30 to a location that suits the user's needs and tastes. Alternative embodiments of the rear fitting member 66 are described below.
As shown in FIG. 3A, the side fitting members 40 of this embodiment include regions 64 at the base of the fingers. The regions 64 may be manufactured of a material that would allow for an increased range of travel for the side fitting members 40. The regions 64 may also have a varied structural thickness with respect to the remainder of the fitting members 40 to thereby vary the flexural characteristics of the fitting members 40 in the region 64. Thus, the fingers may be moved with respect to the rest of the side fitting members 40 to increase the size of the volume 32 or the entryway 34.

Fourth Embodiment

The fourth embodiment of the footwear fit system 28, as shown in FIGS. 4 and 5, illustrates another embodiment of the footwear fit system 28 wherein the fitting members 30 include the side fitting members 40 and the rear fitting member 66. The side fitting members 40 have fingers of a size such that the first terminus 46 and the second terminus 52 overlap one another.
The fitting members 30 bear against the foot 26 when the foot 26 is positioned within the volume to thereby secure the foot 26 within the volume. When incorporated into the footwear member 10, the footwear fit system 28 secures the foot 26 within the footwear member 10. The quantity of fitting members 30 may be selected to vary the amount of pressure applied to the foot 26 and to vary the amount of surface contact between the foot 26 and the fitting members 30. Additionally, the location and shape of the fitting members 30 may also be varied. The amount of force exerted on the foot 26 by each fitting member 30 may be easily adjusted at the manufacturing level by the selection of its material, the material thickness and width, and the degree of deflection incurred when the foot 26 is in place. The padder layer 36 on the inside surface of the fitting members 30 may be installed as desired to adjust pressure, friction and overall comfort.
In one embodiment, the fitting members 30 and the sole 12 are collectively molded as a single element, which is then incorporated into the sole 12 of the shoe or boot. Where the fitting members 30 are hinged at or near the sole 12, a firm fixation and/or integration of the members 30 to the sole 12 is desired. The members 30 may thus be incorporated with a full or partial length shank, as commonly used in footwear construction.

Fifth Embodiment

In another embodiment, as shown in FIGS. 6 and 7, the footwear fit system 28 includes a front fitting member 95 that is attached to the front side 24 of the sole 12. For purposes of the present invention, the front side 24 is considered to include the forward portion of the first and second sides 18 and 20 for cases in which the footwear fit system 28 includes an open toe design. The front fitting member 95 includes a front extension member 96 that extends rearwardly over the top of the foot 26 and applies a pressure against the top of the foot 26 through a foot contacting portion 97. The front fitting member 95 moves upwardly and downwardly between an extended and default position, as described in greater detail above. Since this embodiment is functionally similar to the above-described embodiments, it is not described in greater detail herein.

Sixth Embodiment

With reference to FIG. 8, there is shown a boot-type footwear member 10. The footwear fit system 28 is incorporated between an inner lining 27 of the footwear member 10 and the upper 25, in this case the outer surface of the boot. Thus, the inner lining 27 is interposed between the foot 26 and the fit members 30 when the foot 26 is positioned within the volume 32. In use, the wearer inserts the foot 26 into the inner lining 27 and the foot 26 exerts a force that pushes the fitting members 30 toward the extended position, thereby increasing the volume 32. As the foot 26 moves into the volume 32, the bias in the fitting members 30 moves the fitting members 30 back toward the default position so that the fitting members 30 exert pressure against the foot 26 and secure the foot 26 therein.
It will be appreciated that the footwear fit system 28 could be incorporated in other manners into the footwear member 10. The footwear fit system 28 could also be surrounded by any of a wide variety of uppers 25 or could be secured within an inner lining of the uppers 25. In such cases, the fit system 10 would not be visible but would rather be concealed by the upper 25.

Seventh Embodiment

FIG. 9 illustrates a seventh embodiment of the footwear fit system 28 in which one or more articulating plates 60 are attached to the terminus 46 at least one of the fitting members 30. In the illustrated embodiment, the fit system 28 includes a pair of side fitting members 40 that each have a terminus 46 that are located near the instep region of the foot 26. The plates 60 are preferably connected to the fitting members 40 in such a way that the plates 60 are allowed to articulate about one or more axes, such as with a pivot 62, as shown. The fitting members 40 are resiliently biased to hold the articulating plates 60 against the foot 26. The articulating plates 60 are allowed to assume an orientation substantially matching the contact surface of the foot 26, thus providing relatively even distribution of pressure against the foot 26. The articulating plates 60 may be manufactured of a semi-rigid material that is somewhat flexible, such as pressure formed or injection molded polymer. The articulating plates 60 may also be configured to provide moveable support with progressive resistance through a defined range of motion, such as that desirable in a ski boot or ice skate.

Eighth Embodiment

FIG. 10 illustrates an eigth embodiment of the invention, wherein the footwear fit system 28 is installed in a casual shoe. In this embodiment, the upper 25 is formed as an ordinary casual shoe and the side fitting members 40 are integrated with the upper 25.
This embodiment further includes a tongue element 90 adapted to move from a primary position wherein the tongue element 90 is located between the sole 12 and the first and second foot-bearing portions 44 and 50, to a secondary position wherein the tongue element 90 is located between the first foot-bearing portion 44 and the second foot-bearing portion 50. The tongue element 90 functions to push the first terminus 46 away from the second terminus 52, thereby opening the side fitting members 40 and facilitating the insertion of the foot 26 into the footwear member 10.
The fitting members 30 can be covered, at least in part, by a padded layer 36, as illustrated by FIGS. 11A-11E. The fitting members 30 can also include one or more reinforcing ribs 31 to increase the strength of the fitting members 30, as shown in FIG. 11B, or one or more flex slots 33 can be added, as shown in FIG. 1I D, to soften the contact of the fitting members 30 with the foot 26 of the user.
Heel Portion
In another embodiment, as shown in FIGS. 12-15, the footwear fit system 28 further includes a heel portion 70 positioned adjacent a rear side 22 of the sole 12. The heel portion 70 is preferably resiliently biased to move from a first position adjacent the sole 12 towards a second position above the sole 12. The heel portion 70 includes an elongate heel support 72 that is attached at a first end 74 to the first side 18 and at a second end 76 to the second side 20. The heel portion 70 includes a heel contacting portion 78 between the first and second ends 74 and 76 for contacting the foot 26 of the user to further secure the foot 26 on the sole 12.
As shown in FIGS. 12-13, the heel portion 70 preferably further includes a plurality of roller elements 80 rotatably mounted on the heel contacting portion 78. The roller elements 80 enable the user to step on the heel portion 70 while inserting the foot 26 under the fitting members (not shown in this Figure), and then slide the foot 26 forward so that the heel portion 70 can pivot back to the second position above the sole 12.
In some embodiments, as shown in FIGS. 14 and 15, the heel contacting portion 78 is resilient enough to pivot to the second position without assistance, based on the flexural characteristics of the element. In another embodiment, however, the heel contacting portion 78 further includes a torsion spring element 82 that is operably attached to, or within, the heel portion 70 to bias the heel portion 70 towards the second position.
There are several advantages of the footwear fit system 28:

a) The fitting members 30 allow smooth, seam-free contact areas against the foot 26 for improved comfort.
b) The range of travel designed into the fitting members 30 can allow a wider range of foot 26 shapes to be accommodated in a given size. This could lead to a fewer number of sizes needing to be stocked by the retailer of the footwear member 10. Additional applications could be developed that would allow multiple whole sizes of feet to be secured within a single shoe or boot size. This would provide for efficient use of generic/community footwear stocks, for example, in damage control or fire fighting situations, rental of sports footwear, and longer use of a given article of footwear for growing children.
c) The footwear fit system 28 does not require the mechanical components of laces, hook and pile fasteners, strap clips, or buckles. This offers potential cost savings, but more importantly, allows the foot 26 to be inserted without the need to manually affix, tighten or tie these conventional systems. This could be particularly helpful for elderly or handicapped users who presently need assistance to put on their footwear.
d) As a shoe or boot is used, re-tightening of the laces or other closure system is often required. Since the fitting members 30 exert a continuous pressure onto the foot 26, there is no need to periodically adjust the closure.
e) The fit members 30 may be fabricated of injection molded or pressure formed plastic materials, and tooling expenses will thus be incurred. However, with most or all of the fit system components pre-fabricated in this way, substantial savings in total product costs could be realized with respect to laces, eyelets, straps, fasteners, Velcro, and the labor required to install them. A production method is also foreseen in which the fitting members 30, outsole and padding areas are integrated into a multiple density molding process, with the finished molded product requiring little, if any, additional hand labor.
f) Overall fit quality could be improved using the subject design. It is known that certain areas of the foot 26 are particularly sensitive to pressure. Using fitting members in less sensitive areas can allow secure fitting of the shoe or boot, while reducing or eliminating the pressure at sensitive points which is common with more traditional designs.

Although this invention has been described in terms of certain preferred embodiments, other embodiments that are apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the present invention is intended to be defined only by reference to the appended claims.
All patents, patent applications, and other documents and printed matter cited or referred to in this application is hereby incorporated by reference in full.
