FIELD

The present disclosure relates generally to an article of footwear and more particularly to a sole structure for an article of footwear.

BACKGROUND

This section provides background information related to the present disclosure and is not necessarily prior art.
Articles of footwear conventionally include an upper and a sole structure. The upper may be formed from any suitable material(s) to receive, secure, and support a foot on the sole structure. The upper may cooperate with laces, straps, or other fasteners to adjust the fit of the upper around the foot. A bottom portion of the upper, proximate to a bottom surface of the foot, attaches to the sole structure.
Sole structures generally include a stacked arrangement of a midsole and an outsole extending between a ground surface and the upper. The outsole provides abrasion-resistance and traction with the ground surface and may be formed from rubber or other materials that impart durability and wear-resistance, as well as enhancing traction with the ground surface. The midsole is disposed between the outsole and the upper. While existing sole structures perform adequately for their intended purpose, improvements to sole structures are continuously being sought in order to advance the arts.

DETAILED DESCRIPTION

The present disclosure is directed to sole structures, articles of footwear including the sole structures, methods of manufacturing the sole structures, sole structures manufactured using the methods, methods of manufacturing articles of footwear including the sole structures, and articles of footwear manufactured using the methods. These sole structures provide cushioning as well as lateral stability for articles of footwear. The sole structure includes a cushioning member including a first cushioning element having a first surface and a second surface formed on an opposite side from the first surface, and extending from a first end to a second end. The cushioning member also includes a second cushioning element having a third surface and a fourth surface formed on an opposite side from the third surface, and extending from a third end to a fourth end. A joint is formed between the first cushioning element and the second cushioning element by joining at least one of the third end and the third surface of the second cushioning element to at least one of the second end and the second surface of the first cushioning element, respectively. A fabric panel is disposed within the joint between the first cushioning element and the second cushioning element. The panel can comprise a film or sheet of material, or can comprise textile, such as a knitted textile, a woven textile, a braided textile, a crocheted textile, or a non-woven textile. As the properties of the panel affect the lateral stability of sole structure, in a manufacturing setting, the properties of the sole structure can be easily varied by varying the type of panel used in the sole structure.
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope of those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well known technologies are not described in detail.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of modified features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or sheet is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or sheet, it may be directly on, engaged, connected or coupled to the other element or sheet, or intervening elements or sheets may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or sheet, there may be no intervening elements or sheets present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, sheets and/or sections, these elements, components, regions, sheets and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, sheet or section from another region, sheet or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, sheet or section discussed below could be termed a second element, component, region, sheet or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
With reference to FIGS. 1 and 2 , a first example of an article of footwear 10 constructed according to the principles of the present disclosure is shown. The article of footwear 10 includes a sole structure 100 and an upper 200 attached to the sole structure 100. The footwear 10 may include an anterior end 12 associated with a forward-most point of the footwear 10, and a posterior end 14 corresponding to a rearward-most point of the footwear 10. A longitudinal axis of the footwear 10 extends along a length of the footwear 10 from the anterior end 12 to the posterior end 14, and generally divides the footwear 10 into a lateral side 16 and a medial side 18, respectively corresponding with opposite sides of the footwear 10 and extending from the anterior end 12 to the posterior end 14.
The article of footwear 10 may be divided into one or more regions along the longitudinal axis. The regions may include a forefoot region 20, a mid-foot region 22, and a heel region 24. The forefoot region 20 may correspond with toes and joints connecting metatarsal bones with phalanx bones of a foot. The mid-foot region 22 may correspond with an arch area of the foot, and the heel region 24 may correspond with rear regions of the foot, including a calcaneus bone.
The upper 200 may be described as including a plurality of components that cooperate to define an interior void 202 and an ankle opening 204, which receive and secure a foot for support on the sole structure 100.
Referring now to FIG. 2 , the sole structure 100 of the present disclosure includes a fabric panel 102 partially encapsulated within a cushioning member 104. As discussed below, the cushioning member 104 includes a plurality of cushioning elements 120, 140, 160 joined together with each other at respective joints 110, 112. The cushioning elements 120, 140, 160 cooperate with each other to form a footbed 106 extending along an entire length of the sole structure 100 on the top side, and a ground-engaging surface 108 extending along the length of the sole structure 100 on the bottom side. The portions of the fabric panel 102 may be disposed between adjacent ones of the cushioning elements 120, 140, 160 within the joints 110, 112.
As best shown in FIG. 1 , the cushioning member 104 includes a first cushioning element 120, a second cushioning element 140, and a third cushioning element 160. In the example of FIG. 1 , the first cushioning element 120 is generally disposed within the forefoot region 20 of the sole structure 100, the second cushioning element 140 is generally disposed within the mid-foot region 22 of the sole structure 100, and the third cushioning element 160 is generally disposed within the heel region 24 of the sole structure 100.
Referring to FIG. 2 , the first cushioning element 120 extends from a first end 122 at the anterior end 12 of the article of footwear 10 to a second end 124 at the mid-foot region 22. The first cushioning element 120 includes a top surface 126 forming a portion of the footbed 106 in the forefoot region 20 and a bottom surface 128 formed on an opposite side of the first cushioning element 120 from the top surface 126 and forming a first portion of the ground-engaging surface 108 in the forefoot region 20.
A thickness T₁₂₀of the first cushioning element 120, measured in the direction from the top surface 126 to the bottom surface 128, tapers at the second end 124. In the illustrated example, the thickness T₁₂₀of the first cushioning element 120 tapers in a first direction at the second end 124. Here, the second end 124 of the first cushioning element 120 extends in a direction from the bottom surface 128 towards the top surface 126 and towards the posterior end 14 of the sole structure 100. Accordingly, the second end 124 is formed at an oblique angle relative to the top surface 126 and the bottom surface 128.
In the illustrated example, the second end 124 includes a plurality of steps 130 arranged in series along the second end 124 from the bottom surface 128 to the top surface 126. Each of the steps 130 extends continuously across a width of the first cushioning element 120, from the lateral side 16 to the medial side 18. Accordingly, the thickness T₁₂₀of the first cushioning element 120 tapers incrementally at the second end 124. While the illustrated steps 130 are shown has being square steps 130 each including a vertical face and a horizontal face, in other examples the steps 130 may be angled steps having faces oriented at oblique angles. Optionally, the edges or vertices of the steps 130 may be radiused to form convex or concave curvatures along the widths of the steps 130.
Referring still to FIG. 2 , the second cushioning element 140 extends from a first end 142 adjacent to the forefoot region 20 to a second end 144 adjacent to the heel region 24. Like the first cushioning element 120, the second cushioning element 140 includes a top surface 146 and a bottom surface 148 forming respective portions of the footbed 106 and ground-engaging surface 108 in the mid-foot region 22. A thickness T₁₄₀of the second cushioning element 140, measured in the direction from the top surface 146 to the bottom surface 148, tapers at each of the first end 142 and the second end 144.
In the illustrated example, the thickness T₁₄₀of the second cushioning element 140 tapers in the first direction at the first end 142, such that the first end 142 of the second cushioning element 140 is complementary to (i.e., aligns against) the tapered second end 124 of the first cushioning element 120. Here, the first end 142 of the second cushioning element 140 extends in the direction from the bottom surface 148 towards the top surface 146 and towards the posterior end 14 of the sole structure 100. Accordingly, the first end 142 is formed at an oblique angle relative to the top surface 146 and the bottom surface 148.
The thickness T₁₄₀of the second cushioning element 140 tapers in a second direction at the second end 144. Here, the second end 144 of the second cushioning element 140 extends in the direction from the top surface 146 to the bottom surface 148 and towards the posterior end 14 of the sole structure 100. Accordingly, the second end 144 angles in an opposite direction than the first end 142, such that the first end 142 and the second end 144 converge with each other in the direction from the bottom surface 148 to the top surface 146.
Each of the first end 142 and the second end 144 of the second cushioning element 140 includes a plurality of steps 150 arranged in series from the top surface 146 to the bottom surface 148. The steps 150 of the first end 142 are configured to mate with the steps 130 formed on the second end 124 of the first cushioning element 120 when first end 142 of the second cushioning element 140 is joined to the second end 124 of the first cushioning element 120.
Referring still to FIG. 2 , the third cushioning element 160 extends from a first end 162 adjacent at the mid-foot region 22 to a second end 164 at the posterior end 14. Like the first cushioning element 120, the third cushioning element 160 includes a top surface 166 and a bottom surface 168 forming respective portions of the footbed 106 and the ground-engaging surface 108 in the heel region 24. A thickness T₁₆₀of the third cushioning element 160, measured in the direction from the top surface 166 to the bottom surface 168, tapers at the first end 162.
In the illustrated example, the thickness T₁₆₀of the third cushioning element 160 tapers in the second direction at the first end 162, such that the first end 162 of the third cushioning element 160 is complementary to (i.e., aligns against) the tapered second end 144 of the second cushioning element 140. Here, the first end 162 of the third cushioning element 160 extends in the direction from the top surface 166 towards the bottom surface 168 and towards the posterior end 14 of the sole structure 100. Accordingly, the first end 162 is formed at an oblique angle relative to the top surface 166 and the bottom surface 168.
The first end 162 of the third cushioning element 160 includes a plurality of steps 170 arranged in series from the top surface 146 to the bottom surface 148. The steps 170 of the third cushioning element 160 are configured to engage or mate with the steps 150 formed on the second end 144 of the second cushioning element 140 when first end 162 of the third cushioning element 160 is joined to the second end 144 of the second cushioning element 140.
As provided above, when the sole structure 100 is assembled, the second end 124 of the first cushioning element 120 and the first end 142 of the second cushioning element 140 are joined together and cooperate to form the first joint 110 of the cushioning member 104 between the forefoot region 20 and the mid-foot region 22. Similarly, the second end 144 of the second cushioning element 140 and the first end 162 of the third cushioning element 160 are joined together and cooperate to form the second joint 112 of the cushioning member 104 between the mid-foot region 22 and the heel region 24.

In view of the substantial similarity in structure and function of the components associated with the article of footwear 10 with respect to the article of footwear 10 f, like reference numerals are used hereinafter and in the drawings to identify like components, while like reference numerals containing letter extensions are used to identify those components that have been modified.
In the example of FIGS. 13 and 14 , the sole structure 100 f includes a fabric panel 102 f and a cushioning member 104 f. The cushioning member 104 f includes a first cushioning element 120 f and a second cushioning element 140 f received within a lower portion of the first cushioning element 120 f. As explained below, the first cushioning element 120 f and the second cushioning element 140 f cooperate with the fabric panel 102 f to form a joint 110 f in an intermediate portion of the cushioning member 104 f.
As shown in FIGS. 13 and 14 , the first cushioning element 120 f extends continuously along the entire length of the sole structure 100 f from a first end 122 f at the anterior end 12 to a second end 124 f at the posterior end 14. Here, the top surface 126 f of the first cushioning element 120 f is continuous and uninterrupted from the first end 122 f to the second end 124 and defines the footbed 106 of the cushioning member 104 f. However, the bottom surface 128 f of the first cushioning element 120 f includes a receptacle 132 f configured to receive the second cushioning element 140 f therein. As shown, the receptacle 132 f extends continuously through a width of the first cushioning element 120 f, from the lateral side 16 to the medial side 18. Here, the receptacle 132 has a plurality of sides defining a polygonal cross section corresponding to a shape of the second cushioning element 140 f, as discussed below.
The second cushioning element 140 f extends from a first end 142 f to a second end 144 f, and includes a top surface 146 f and a bottom surface 148 f formed on an opposite side from the top surface 146 f. As shown, the top surface 146 f and the bottom surface 148 f are substantially parallel to each other. A thickness T_140fof the second cushioning element 140 f is measured along a direction from the top surface 146 f to the bottom surface 148 f, and tapers at each of the first end 142 f and the second end 144 f. The first end 142 f of the second cushioning element 140 f tapers in the first direction such that the first end 142 f extends from the bottom surface 148 f to the top surface 146 f and towards the posterior end 14.

Accordingly, the second cushioning element 140 f has a trapezoidal cross section extending across a width of the sole structure 100 f.
As set forth above, the second cushioning element 140 f is configured to be received within the receptacle 132 f formed in the bottom portion of the first cushioning element 120 f. As shown, the receptacle 132 f and the second cushioning element 140 f are disposed within the mid-foot region such that the first end 142 f of the second cushioning element 140 f is disposed adjacent to the forefoot region 20 and the second end 144 f of the second cushioning element 140 f is disposed adjacent to the heel region 24.
The receptacle 132 f is partially formed through the thickness T_120fof the first cushioning element 120 f from the bottom surface 128 f. Similarly, the maximum thickness T_140fof the second cushioning element 140 f, measured from the top surface 146 f to the bottom surface 148 f, is less than the maximum thickness T_120fof the first cushioning element 120 f. Accordingly, when the second cushioning element 140 f is disposed within the receptacle 132 f, the top surface 146 f of the second cushioning element is positioned between the top surface 126 f and the bottom surface 128 f of the first cushioning element 120 f, while the bottom surface 148 f of the second cushioning element 140 f is flush with the bottom surface 128 f of the first cushioning element 120 f. As such, the bottom surfaces 128 f, 148 f cooperate to form the ground-engaging surface 108 of the sole structure 100 f.
When the sole structure 100 f is assembled, the fabric panel 102 f is interposed between the second cushioning element 140 f and the receptacle 132 f to form a first joint 110 f of the sole structure 100 f.

When the resilient polymeric material is a foamed polymeric material, the foamed material may be foamed using a physical blowing agent which phase transitions to a gas based on a change in temperature and/or pressure, or a chemical blowing agent which forms a gas when heated above its activation temperature. For example, the chemical blowing agent may be an azo compound such as adodicarbonamide, sodium bicarbonate, and/or an isocyanate.
In some embodiments, the foamed polymeric material may be a crosslinked foamed material. In these embodiments, a peroxide-based crosslinking agent such as dicumyl peroxide may be used. Furthermore, the foamed polymeric material may include one or more fillers such as pigments, modified or natural clays, modified or unmodified synthetic clays, talc glass fiber, powdered glass, modified or natural silica, calcium carbonate, mica, paper, wood chips, and the like.
The resilient polymeric material may be formed using a molding process. In one example, when the resilient polymeric material is a molded elastomer, the uncured elastomer (e.g., rubber) may be mixed in a Banbury mixer with an optional filler and a curing package such as a sulfur-based or peroxide-based curing package, calendared, formed into shape, placed in a mold, and vulcanized.
In another example, when the resilient polymeric material is a foamed material, the material may be foamed during a molding process, such as an injection molding process. A thermoplastic polymeric material may be melted in the barrel of an injection molding system and combined with a physical or chemical blowing agent and optionally a crosslinking agent, and then injected into a mold under conditions which activate the blowing agent, forming a molded foam.
Optionally, when the resilient polymeric material is a foamed material, the foamed material may be a compression molded foam. Compression molding may be used to alter the physical properties (e.g., density, stiffness and/or durometer) of a foam, or to alter the physical appearance of the foam (e.g., to fuse two or more pieces of foam, to shape the foam, etc.), or both.
The compression molding process desirably starts by forming one or more foam preforms, such as by injection molding and foaming a polymeric material, by forming foamed particles or beads, by cutting foamed sheet stock, and the like. The compression molded foam may then be made by placing the one or more preforms formed of foamed polymeric material(s) in a compression mold, and applying sufficient pressure to the one or more preforms to compress the one or more preforms in a closed mold. Once the mold is closed, sufficient heat and/or pressure is applied to the one or more preforms in the closed mold for a sufficient duration of time to alter the preform(s) by forming a skin on the outer surface of the compression molded foam, fuse individual foam particles to each other, permanently increase the density of the foam(s), or any combination thereof. Following the heating and/or application of pressure, the mold is opened and the molded foam article is removed from the mold.
With continued reference to the figures, the fabric panels 102-102 w may be formed from a textile. The textile can be formed by manipulating one or more fibers, filaments or yarns, using techniques such as knitting, weaving, braiding, felting, hydroentanglement, etc. Similarly, when one or more cables is included in the sole structure, the cable can be formed from one or more fibers, filaments or yarns using a knitting or braining technique. The filaments and/or fibers used to form the yarns or fibers can comprise a polymeric material such as, for example, a thermoplastic material. An exemplary thermoplastic material may include, for example, a thermoplastic polyurethane, a thermoplastic polyamide, a thermoplastic polyether, a thermoplastic polyester, a thermoplastic polyolefin, any combination thereof, or the like. In some instances, the panel is porous. In some examples, if the panel is a textile, the textile may include a polyester yarn. Furthermore, in other examples, if the panel is a textile including apertures or passages between overlapping or entangled filaments, fibers or yarns, each passage or aperture defining the structure of the textile may be at least 0.5 mm in length in a largest dimension or at least 1.0 mm in length in a largest dimension. In some instances, the panel includes an embroidered textile and has one or more first regions including embroidery and one or more second regions without embroidery or with a lower percentage of embroidered surface area as comparted to the one or more first regions. The embroidery can provide reduced stretch or a “lock down” feature to areas of the panel. In some examples, or in some portions of the upper, the panel may stretch in a single direction. In other examples, or in other portions, the panel may stretch multi-directionally.
