Definitions
- the present invention relates to footwear.
- the invention concerns, more particularly, a cushioning component suitable for footwear applications, wherein the cushioning component includes a lobed chamber and inserts positioned between the lobes.
- a conventional article of footwear includes two primary elements, an upper and a sole structure.
- the upper generally includes multiple material layers, such as textiles, foam, and leather, that are stitched or adhesively bonded together to form a void on the interior of the footwear for securely and comfortably receiving a foot.
- the sole structure has a layered configuration that includes an insole, a midsole, and an outsole.
- the insole is a thin cushioning member positioned within the void and adjacent the foot to enhance footwear comfort.
- the midsole forms a middle layer of the sole structure and is often formed of a foam material, such as polyurethane or ethylvinylacetate.
- the outsole is secured to a lower surface of the midsole and provides a durable, wear-resistant surface for engaging the ground.
- Midsoles formed of conventional foam materials compress resiliently under an applied load, thereby attenuating forces and absorbing energy associated with walking or running, for example.
- the resilient compression of the foam materials is due, in part, to the inclusion of cells within the foam structure that define an inner volume substantially displaced by gas. That is, the foam materials include a plurality of pockets that enclose air. After repeated compressions, however, the cell structures may begin to collapse, which results in decreased compressibility of the foam. Accordingly, the overall ability of the midsole to attenuate forces and absorb energy deteriorates over the life of the midsole.
- One manner of minimizing the effects of the cell structure collapse in conventional foam materials involves the use of a structure having the configuration of a fluid-filled chamber, as disclosed in U.S.
- the fluid-filled chamber has the structure of a bladder that includes an outer enclosing member formed of an elastomeric material that defines a plurality of tubular members extending longitudinally throughout the length of an article of footwear.
- the tubular members are in fluid communication with each other and jointly extend across the width of the footwear.
- U.S. Patent Number 4,219,945 to Rudy also incorporated by reference, discloses a similar fluid-filled chamber encapsulated in a foam material, wherein the combination of the fluid-filled chamber and the encapsulating foam material functions as a midsole.
- U.S. Patent Number 4,817,304 to Parker, et ab discloses a foam-encapsulated, fluid-filled chamber in which apertures are formed in the foam and along side portions of the chamber.
- the apertures provide decreased stiffness during compression of the midsole, while reducing the overall weight of the footwear.
- the overall impact response characteristics may be adjusted in specific areas of the footwear.
- the fluid-filled chambers described above may be manufactured by a two-film technique, wherein two separate layers of elastomeric film are formed to have the overall shape of the chamber.
- the layers are then welded together along their respective peripheries to form an upper surface, a lower surface, and sidewalls of the chamber, and the layers are welded together at predetermined interior locations to impart a desired configuration to the chamber. That is, interior portions of the layers are connected to form chambers of a predetermined shape and size at desired locations.
- the chambers are subsequently pressurized above ambient pressure by inserting a nozzle or needle, which is connected to a fluid pressure source, into a fill inlet formed in the chamber.
- Another manufacturing technique for manufacturing fluid-filled chambers of the type described above is through a blow-molding process, wherein a liquefied elastomeric material is placed in a mold having the desired overall shape and configuration of the chamber.
- the mold has an opening at one location through which pressurized air is provided. The pressurized air forces the liquefied elastomeric material against the inner surfaces of the mold and causes the material to harden in the mold, thereby forming the chamber to have the desired configuration.
- the chambers comprise a hermetically sealed outer barrier layer that is securely bonded over a double-walled fabric core.
- the double-walled fabric core has upper and lower outer fabric layers normally spaced apart from each another at a predetermined distance, and may be manufactured through a double needle bar Raschel knitting process.
- Connecting yarns potentially in the form of multi-filament yarns with many individual fibers, extend internally between the facing surfaces of the fabric layers and are anchored to the fabric layers.
- the individual filaments of the connecting yarns form tensile restraining members that limit outward movement of the barrier layers to a desired distance.
- the assembled shell, covering layer, and core are then moved to a lamination station where radio frequency energy bonds opposite sides of the core to the shell and covering layer, and bonds a periphery of the shell to the covering layer.
- the chamber is then pressurized by inserting a fluid so as to place the connecting yarns in tension.
- a process for thermoforming a chamber is disclosed in U.S. Patent Number 5,976,451 to Skaja et ab, hereby incorporated by reference, wherein a pair of flexible thermoplastic resin layers are heated and placed against a pair of molds, with a vacuum drawing the layers into the mold. The layers are then pressed together to form the chamber.
- the fluid contained within the chambers discussed above may include any of the gasses disclosed in U.S. Patent Number 4,340,626 to Rudy, such as hexafluoroethane and sulfur hexafluoride, for example.
- some chambers enclose gasses that include pressurized octafluorapropane, nitrogen, or air.
- the material forming outer layers of the chambers discussed above may be formed of a polymer material, such as a thermoplastic elastomer, that is substantially impermeable to the fluid within the chamber. More specifically, one suitable material is a film formed of alternating layers of thermoplastic polyurethane and ethylene-vinyl alcohol copolymer, as disclosed in U.S.
- Patent Numbers 5,713,141 and 5,952,065 to Mitchell et ab hereby incorporated by reference.
- a variation upon this material wherein the center layer is formed of ethylene-vinyl alcohol copolymer; the two layers adjacent to the center layer are formed of thermoplastic polyurethane; and the outer layers are formed of a regrind material of thermoplastic polyurethane and ethylene-vinyl alcohol copolymer may also be utilized.
- Another suitable material is a flexible microlayer membrane that includes alternating layers of a gas barrier material and an elastomeric material, as disclosed in U.S. Patent Numbers 6,082,025 and 6,127,026 to Bonk et ab, both hereby incorporated by reference.
- thermoplastic elastomer materials or films include polyurethane, polyester, polyester polyurethane, polyether polyurethane, such as cast or extruded ester-based polyurethane film. Additional suitable materials are disclosed in the '156 and '945 patents to Rudy, which were discussed above, hi addition, numerous thermoplastic urethanes may be utilized, such as PELLETHANE, a product of the Dow Chemical Company; ELASTOLLAN, a product of the BASF Corporation; and ESTANE, a product of the B.F. Goodrich Company, all of which are either ester or ether based.
- thermoplastic urethanes based on polyesters, polyethers, polycaprolactone, and polycarbonate macrogels may be employed, and various nitrogen blocking materials may also be utilized.
- Further suitable materials include thermoplastic films containing a crystalline material, as disclosed in U.S. Patent Numbers 4,936,029 and 5,042,176 to Rudy, hereby incorporated by reference, and polyurethane including a polyester polyob as disclosed in U.S. Patent Numbers 6,013,340; 6,203,868; and 6,321,465 to Bonk et ab, also hereby incorporated by reference.
- the chambers discussed above are generally encapsulated within a polymer foam, which forms the midsole of the footwear.
- the chambers disclosed in U.S. Patent Numbers 5,572,804 to Skaja et al. and 6,029,962 to Shorten et ab, both hereby incorporated by reference, are formed of polymer layers with a plurality of indentations extending inward on opposite sides of the chamber. Indentations on a top surface of the chamber contact and are bonded with corresponding indentations on a bottom side of the chamber to restrain outward movement of the polymer layers.
- polymer elements having shapes that correspond with the shapes of the indentations are positioned within the indentations and bonded to the exterior of the bladder to provide additional support.
- the chamber and the polymer elements are then encapsulated within a foam material to form a midsole.
- the present invention is a cushioning component for an article of footwear that includes a chamber and a plurality of inserts.
- the chamber has a first surface and an opposite second surface peripherally joined to form a volume for receiving a fluid.
- the first surface and the second surface are devoid of internal connections that secure interior portions of the first surface to interior portions of the second surface, and the first surface and the second surface define a plurality of lobes extending outward from a central area of the chamber.
- the lobes are in fluid communication with the central area, and the lobes define spaces positioned between the lobes that are located adjacent to each other.
- the inserts are positioned within the spaces and formed of a resilient material.
- Layers of material extend over the first surface and the second surface, and the inserts are secured to the layers of material such that the inserts extend between the lobes of the chamber.
- Each insert includes a first portion positioned adjacent the first surface and a second portion positioned adjacent the second surface, with first portion being secured to the second portion.
- the first portion is formed of three concave structures
- the second portion is also formed of three concave structures.
- the fluid within the chamber may be at a pressure that is substantially equal to the ambient pressure surrounding the footwear, and the fluid may be air, for example.
- the relatively low pressure permits the first surface and the second surface to retain a desired shape without the internal connections between the first surface and the second surface. That is, the relatively low pressure permits the first surface and the second surface to have a flat or curved shape without the need for tensile members located within the chamber that restrain outward movement in some pressurized chambers.

- FIG. 1 An article of footwear 10 is depicted in Figure 1 and includes an upper 20 and a sole structure 30.
- Upper 20 has a substantially conventional configuration and includes a plurality of elements, such as textiles, foam, and leather materials, that are stitched or adhesively bonded together to form an interior void for securely and comfortably receiving the foot.
- Sole structure 30 is positioned below upper 20 and includes two primary elements, a midsole 31 and an outsole 32.
- Midsole 31 is secured to a lower surface of upper 20, through stitching or adhesive bonding for example, and operates to attenuate forces and absorb energy as sole structure 30 contacts the ground. That is, midsole 31 is structured to provide the foot with cushioning during walking or running, for example.
- Outsole 32 is secured to a lower surface of midsole 31 and is formed of a durable, wear-resistant material that engages the ground.
- sole structure 30 may include an insole 33, which is a thin cushioning member, located within the void and adjacent to the foot to enhance the comfort of footwear 10.
- Midsole 31 is primarily formed of a polymer foam material, such as polyurethane or ethylvinylacetate, that at least partially encapsulates a cushioning component 40.
- Component 40 is utilized to supplement the force attenuation and energy absorption properties of midsole 31, thereby providing additional cushioning to sole structure 30.
- component 40 may enhance the stability of sole structure 30.
- a desired degree of cushioning and stability is imparted by pressure ramping, the structural and material properties of component 40, and film tensioning.
- component 40 is substantially coextensive with an upper surface of midsole 31. Accordingly, the upper surface of component 40 is generally coplanar with the upper surface of the polymer foam material forming midsole 31. In other embodiments, however, component 40 may be embedded within the foam material of midsole 31, or maybe substantially coextensive with a lower surface of midsole 31, for example.
- Component 40 is also depicted as being positioned in a heel region of midsole 31, which generally corresponds with the area of highest initial load during footstrike. Component 40 may, however, be positioned in any region of midsole 31 to obtain a desired degree of cushioning response.
- a portion of component 40 may extend to an edge 34 of midsole 31, and may extend through edge 34 such that component 40 is visible from the exterior of footwear 10, as depicted in Figures 1-3.
- the edges of chamber 40 may be entirely embedded within the foam material of midsole 31, as depicted in the alternate embodiment of Figures 16-18.
- midsole 31 may include multiple components having the general configuration of component 40. The extent to which the foam material extends into the contours of component 40 may also vary. As depicted in Figure 4, the foam material extends along upper and lower surfaces of component 40, and the foam material extends into indentations 66 and 67. In some embodiments, however, the foam material may be absent from indentations 66 and 67.
- the primary elements of component 40 are a chamber 50 and a covering element 60.
- Chamber 50 has a first surface 51 and an opposite second surface 52 that are bonded together to form a peripheral seam 53.
- Portions of surfaces 51 and 52 have a generally planar configuration and are uniformly spaced apart from each other. In other embodiments one or both of first surface 51 and second surface 52 may be curved or may have an otherwise contoured configuration.
- the areas of surfaces 51 and 52 immediately adjacent to peripheral seam 53 form a sidewall 54 of chamber 50.
- Surfaces 51 and 52 each form a central area 55 and six lobes 56a-56f extending outward from central area 55.
- Lobes 56a-56f each have a distal end 57a-57f, respectively, positioned opposite central area 55. Although six lobes 56a-56f are depicted and discussed herein, any number of lobes ranging from three to twenty is intended to fall within the scope of the present invention. A suitable number of lobes, however, ranges from five to nine.
- Chamber 50 is depicted separate from covering element 60 in Figures 10-12. In forming lobes 56a-56f portions of the polymer material of surfaces 51 and 52 are bonded together between lobes 56a-56f to form bonded areas 58a-58e, which provide an area for securing covering element 60 to chamber 50.
- chamber 50 A variety of materials may be utilized to form chamber 50, including the polymeric materials that are conventionally utilized in forming the outer layers of fluid-filled chambers for footwear, as discussed in the Background of the Invention section.
- the fluid within chamber 50 is at ambient pressure or at a pressure that is slightly elevated from ambient. Accordingly, the pressure of the fluid within chamber 50 may range from a gauge pressure of zero to five pounds per square inch. In further embodiments of chamber 50, however, the pressure of the fluid within chamber 50 may exceed five pounds per square inch. Due to the relatively low pressure within chamber 50, the materials utilized to form first surface 51 and second surface 52 need not provide the barrier characteristics that operate to retain the relatively high fluid pressures of prior art chambers.
- first surface 51 and second surface 52 may have a thickness of approximately 0.040 inches, and may range from 0.030 to 0.060 inches, for example.
- the relatively low pressure of the fluid within chamber 50 also provides another difference between chamber 50 and prior art chambers.
- Chamber 50 may be manufactured through a variety of manufacturing techniques, including blow-molding, thermoforming, and rotational molding, for example.
- blow-molding technique thermoplastic material is placed in a mold having the general shape of chamber 50 and pressurized air is utilized to induce the material to coat surfaces of the mold.
- thermoforming technique layers of thermoplastic material are placed between corresponding portions of a mold, and the mold is utilized to compress the layers together at peripheral locations of chamber 50.
- a positive pressure may be applied between the layers of thermoplastic material to induce the layers into the contours of the mold.
- a vacuum may be induced in the area between the layers and the mold to draw the layers into the contours of the mold.
- chamber 50 The structure of chamber 50 disclosed herein is intended to provide an example of a suitable fluid-filled bladder for component 40.
- chamber 50 may have lesser or greater numbers of lobes 56a-56f, bonded areas 58a-58e may be absent, the fluid pressure within chamber 50 may be substantially greater than ambient pressure, or peripheral seam 53 may be located adjacent the planar area of first surface 51 to enhance visibility through sidewall 54, for example.
- Covering element 60 extends over surfaces 51 and 52 and extends between adjacent lobes 56a-56f.
- the primary portions of covering element 60 are a first layer 61 that is positioned adjacent to first surface 51, a second layer 62 that is positioned adjacent to second surface 52, and a plurality of inserts 63 that extend between and connect layers 61 and 62.
- first layer 61 has a generally planar structure that contacts and extends over the planar area of first surface 51. Accordingly, first layer 61 provides a thin, planar member that covers portions of first surface 51.
- second layer 62 has a generally planar structure that contacts and extends over the planar area of second surface 52.
- first layer 61 and second layer 62 may have a curved or otherwise contoured configuration.
- Inserts 63 are positioned between adjacent lobes 56a-56f, and inserts 63 extend along sidewall 54 to connect first layer 61 and second layer 62. Accordingly, layers 61 and 62 are secured together and secured to chamber 50 by inserts 63. Although inserts 63 are sufficient to secure the position of layers 61 and 62 relative to chamber 50, an adhesive may also be utilized to generally secure covering element 60 to chamber 50. As discussed, inserts 63 are positioned between lobes 56a-56f. Accordingly, distal ends 57a-57f protrude outward between inserts 63 and are visible from sides of component 40. Alternately, the length of lobes 56a-56f may be decreased such that distal ends 57a-57f are not visible.
- Each insert 63 includes a first portion 64 that is connected to a second portion 65.
- First portion 64 has a concave structure and lies adjacent to the area of sidewall 54 formed by first surface 51.
- each first portion 64 includes an indentation 66 having three depressed areas arranged in a Y configuration that form a structure generally resembling a clover leaf.
- the three depressed areas in each indentation 66 are arranged, therefore, in a generally triangular pattern, with one of the depressed areas being spaced inward from sides of component 40 and two of the depressed areas forming the sides of component 40.
- each second portion 65 includes an indentation 67 having three depressed areas arranged in a Y configuration that form a structure generally resembling a clover leaf.
- the three depressed areas in each indentation 67 are arranged, therefore, in a generally triangular pattern, with one of the depressed areas being spaced inward from sides of component 40 and two of the depressed areas forming the sides of component 40.
- inserts 63 may form a structure that extends through the spaces between lobes 56a-56f.
- inserts 63 have a rounded shape, and indentations 66 and 67 cooperatively taper to a lesser width adjacent to peripheral seam 53.
- inserts 63 and indentations 66 and 67 may have a constant thickness or may taper outwards.
- inserts 63 generally extend through the spaces between lobes 56a-56f.
- first layer 61 may be formed integral with each first portion 64.
- second layer 62 may be formed integral with each second portion 65.
- First layer 61 and second layer 62 are then positioned on opposite sides of chamber 50 such that each first portion 64 aligns with each second portion 65. Bonds are then formed between each first portion 64 and second portion 65 to secure covering element 60 to chamber 50.
- Each indentation 66 and 67 is positioned adjacent to one of bonded areas 58a-58e such that bonded areas 58a-58e extend between at least a portion of each adjacent first portion 64 and second portion 65. Accordingly, each first portion 64 and each second portion 65 are effectively bonded to bonded areas 58a-58e. In general, however, bonded areas 58a-58e do not extend between exterior portions of first portions 64 and second portions 65. Accordingly, exterior portions of first portions 64 and second portions 65 are bonded directly to each other.
- covering element 60 may be formed of a thermoplastic polyurethane or PEBAX, which is manufactured by the Atofina Company.
- PEBAX which is a polyether block amide, provides a variety of characteristics that benefit the present invention, including high impact resistance at low temperatures, few property variations in the temperature range of -40 degrees Celsius to positive 80 degrees Celsius, resistance to degradation by a variety of chemicals, and low hysteresis during alternative flexure.
- Composite materials may also be formed by incorporating glass fibers or carbon fibers into the polymer materials discussed above.
- FIG. 13-15 Another embodiment of the present invention is depicted in Figures 13-15 as a cushioning component 40', which includes a chamber 50' and a covering element 60'.
- Chamber 50' has the general configuration of chamber 50.
- covering element 60' has the general configuration of covering element 60.
- covering element 60' includes a first layer 61' and a second layer 62' that are connected by inserts 63'.
- First layer 61 ' has a plurality of first portions 64'
- second layer 62' has a plurality of second portions 65'
- inserts 63' have a reinforced structure.
- indentations 66' and 67' have a thicker, more- substantial construction, and each of indentations 66' and 67' have interior walls 68'. Interior walls 68' have a Y-shaped structure and operates to decrease the compressibility of each insert 63' due to the effects of hoop stress. As inserts 63' are positioned on peripheral portions of component 40, the decreased compressibility correspondingly increases the stiffness of the peripheral portions.
- inserts 63 and inserts 63' may be made to inserts 63 and inserts 63' to modify the overall compressibility of component 40.
- component 40 Due to the substantially ambient fluid pressure, component 40 produces a relatively large deflection for a given load during initial stages of compression when compared to some of the fluid-filled chambers discussed in the Background of the Invention section. As component 40 is compressed, component 40 provides force attenuation and energy absorption, otherwise referred to as cushioning. As the compression of component 40 increases, however, the stiffness of component 40 increases in a corresponding manner due to the structure of component 40 and the manner in which component 40 is incorporated into midsole 31. Three phenomena operate simultaneously to produce the effect described above and include pressure ramping, the properties of inserts 63, and film tensioning. Each of these phenomena will be described in greater detail below.
- Pressure ramping is the increase in pressure within chamber 50 that occurs as a result of compressing chamber 50.
- chamber 50 has an initial pressure and initial volume when not being compressed within midsole 31.
- the effective volume of chamber 50 decreases, thereby increasing the pressure of the fluid within chamber 50.
- the increase in pressure operates to provide a portion of the cushioning response of component 40. Accordingly, the volume of chamber 50 may be controlled through the design of chamber 50, thereby controlling the pressure ramping effect in component 40.
- inserts 63 also affect the cushioning response of midsole 31.
- inserts 63 may be modified to have a thicker, more-substantial construction, as with inserts 63'. This decreases the compressibility of component 40 and affects the cushioning response of midsole 31.
- interior walls 68' may be formed to further decrease the compressibility of component 40.
- inserts 63 may be a solid structure that does not include indentations 66 or indentations 67.
- the compressibility of component 40 may also be modified by varying the material that is utilized to form covering element 60. A change in the number of lobes 56a-56f may be utilized, for example, to decrease or increase the number of inserts 63. Accordingly, the geometry and materials utilized for inserts 63, the number of inserts 63, and the corresponding geometry of chamber 50 may be modified to have an effect upon the cushioning response.
- the cushioning response of midsole 31 is modifiable to . provide a desired degree of force attenuation and energy absorption.
- the volume of chamber 50, the number and shape of lobes 56a-56f, the specific configuration of inserts 63a-63e, the thickness and materials that form surfaces 51 and 52, the thickness and materials utilized to form covering element 60, and the position and orientation of component 40 within midsole 31 may be varied to modify the cushioning response.
- the properties of inserts 63, including wall thickness and material may also be adjusted to modify the cushioning response.
- the compressibility of inserts 63a-63e may be selected to be greater than the compressibility of chamber 50 for an initial degree of compression of midsole 31.
- midsole 31 may be custom tailored to a specific individual or to provide a specific cushioning response during compression.
- first layer 61 and second layer 62 are depicted in the figures as having a continuous, sheet-style configuration. Alternately, first layer 61 and second layer 62 may have the configuration of a web that is formed of a plurality of interconnected segments, or first layer 61 and second layer 62 may define a plurality of apertures, for example. Furthermore, first layer 61 and second layer 62 may be entirely absent in some embodiments such that covering element 60 includes only inserts 63.
- inserts 63 are depicted as extending between each of the adjacent lobes 56a-56f, but maybe absent between some lobes 56a- 56f in order to increase compressibility in those areas.
- Each of inserts 63 may also be formed to have a different structure in order to tune the compressive response of component 40.
- the inserts 63 positioned in a rear, lateral corner of footwear 10 may be structured to exhibit greater compressibility than other inserts 63 to impart greater compressibility to the area of footwear 10 that initially contacts the ground during the running cycle.
- the inserts 63 in a basketball shoe may each have a substantially similar structure to provide uniform compressibility, and thereby impart stability.
