Definitions

  • the present invention relates to shoes and more particularly to a sole structure for shoes.
  • the sole structure includes a fluid-filled insert secured within it in a manner which maximizes the effectiveness and visibility of the insert.
  • the sole of a running shoe must provide traction, protection, and a durable wear surface.
  • the considerable forces generated by running require that the sole of a running shoe provide enhanced protection and shock absorption for the foot and leg. It is also desirable to have enhanced protection and shock absorption for the foot and leg in all types of footwear.
  • the sole of a running shoe typically includes several layers, including a resilient, shock absorbent material as a midsole and a ground contacting outer sole or outsole, which provides both durability and traction. This Is particularly true for training or jogging shoes designed to be used over long distances and over a long period of time.
  • the sole also provides a broad, stable base to support the foot during ground contact.
  • the typical midsole uses one or more materials or components which affect the force of impact in two important ways, i.e. through shock absorption and energy absorption.
  • Shock absorption involves the attenuation of harmful impact forces.
  • a midsole with high shock absorbing characteristics thus can provide enhanced foot protection, assuming other factors such as stability are not compromised.
  • Energy absorption is simply the general soaking up of both impact and useful propulsive forces.
  • a midsole with high energy absorbing characteristics has relatively lower resiliency, and generally does not return much of the energy placed into a midsole at foot impact. This results in less efficiency in foot motion and a "flat" feel.
  • a midsole with low energy absorbing characteristics has relatively higher resiliency, and generally returns more of the energy placed into a midsole at foot impact.
  • Fluid filled inserts of the type disclosed In U.S. patent Nos. 4,183,156 and 4,219,945 to Marion F. Rudy provide a cushioning effect for the foot which is superior to foamed polymeric materials that have been used in the past as cushioning materials.
  • the inserts disclosed in the '156 and '945 patents provide an appropriate balance of shock absorption and resiliency.
  • Another advantage of these inserts is that they exhibit good hysteresis, i.e., can be deformed and still come back to their original shape. Even though the deforming of the insert occurs repeatedly, the insert will still return to its original shape.
  • foamed polymeric materials such as polyurethane (PU) and ethyl vinyl acetate (EVA) foams, as well as solid plastics such as HYTREL®, which are currently used in athletic shoes, since these materials may not return to their original shape after prolonged compressive use.
  • PU polyurethane
  • EVA ethyl vinyl acetate
  • the sole structure in the '156 and '945 patents forms a fluid-filled insert or insole barrier member of an elastomer material having a multiplicity of preferably intercommunicating, fluid-containing chambers inflated to a relatively high pressure by a gas having a low diffusion rate through the elastomer material, the gas being supplemented by ambient air diffusing through the elastomer material into the chambers to increase the pressure therein, the pressure remaining at or above its initial value over a period of years.
  • the fluid-filled insert is incorporated into the insole structure, in the '156 patent, by placement within a cavity below the upper, e.g. on top of a midsole layer and within sides of the upper or midsole layer.
  • a ventilated moderator formed of a sheet of semi-flexible material is placed over the fluid-filled insert.
  • the insert is encapsulated within a yieldable foam material, which functions as a bridging moderator filling in irregularities of the insert, providing a substantially smooth and contoured surface for supporting the foot and forming an easily handled structure for attachment of an upper.
  • the encapsulating foam material also functions to hold the fluid-filled insert in position with the midsole.
  • Parker et al. U.S. Patent No. 4,817,304, discloses a shoe which uses the combination of a fluid-filled insert and encapsulating foam material, as disclosed in the '945 Rudy patent, but which provides a mechanism for adjusting the impact response of this combination.
  • the adjustment mechanism includes a gap formed on at least one side of the insert to allow the fluid-filled insert to expand. This expansion allows the effect of the insert to dominate the impact response of the sole structure in the area adjacent the gap. While such localized impact response dominance is important to adjusting the impact response of the sole structure, in view of the advantageous characteristics of the '945 patent fluid-filled inserts, it would be desirable to have the impact response of the inserts dominate over a broader area.
  • One aspect of the sole structure in accordance with the present invention is directed to this objective.
  • Another aspect of the sole-structure disclosed in the '304 Parker et al. patent is directed to the visibility of the fluid-filled insert through the gap, as well as of internal portions of the sole through the transparent material of the fluid-filled insert.
  • the degree of visibility is limited by the size of the gap, which itself is limited since the foam material of the midsole must perform the function of positioning and holding the fluid-filled insert within the sole structure. Visibility of the internal portions of a sole structure allows a person to see how a midsole functions. Internal visibility is particularly desirable when fluid-filled inserts are used in the sole structure. Millions of athletic shoes have been sold commercially with fluid-filled inserts of the type disclosed in the '945 and '304 patents, and failures of the inserts in these shoes have been extremely rare.
  • Sole structures which allow internal visibility are disclosed in other patents such as U.S. Patent No. 4,391,048 to Lutz and U.S. Patent No. 4,845,863 to Yung-Mao.
  • Lutz '048 visibility is provided through a small window in the bottom of an outsole formed of a transparent or translucent insert, or of a section of smaller thickness in an at least partially translucent outsole.
  • Very limited visibility is provided through such a small window.
  • Yung-Mao '863 visibility is provided through a relatively small aperture formed in either the bottom of the outsole or the side of the midsole. The viewing aperture is filled in with a transparent material.
  • One potential disadvantage of providing visibility through an aperture in the sole structure is that removal of the material of the sole structure for the aperture weakens the sole structure. This is not the case with shoes made according to the teachings of the '304 Parker et al. patent, since a fluid-filled insert with superior cushioning capability fills at least a portion of the aperture. However, in other systems where the aperture remains unfilled, or is filled with a rigid or semi-rigid transparent plastic material, the cushioning capability of the sole can be adversely effected.
  • Another aspect of the sole structure in accordance with the present invention is to provide a broad degree of visibility of internal portions of the sole without the use of apertures and without adversely affecting the cushioning characteristics of the midsole.
  • the present invention relates to a shoe which incorporates an improved sole structure.
  • the sole structure has a configuration which permits a fluid-filled insert to dominate the impact response characteristics of the sole structure in the area of the insert.
  • the sole structure also provides for a broad degree of visibility of internal portions of a midsole.
  • the sole structure includes an outsole and a fluid-filled insert.
  • the outsole has a lower surface with a tractive surface for producing frictional contact and an upper surface.
  • the outsole upper surface has a mechanism for positioning the fluid-filled insert in the sole structure, and the fluid-filled insert has a mechanism for cooperating with the positioning mechanism.
  • the positioning mechanism includes a plurality of projections extending from the upper surface of the outsole with corresponding or mating recesses in the bottom surface of the fluid-filled insert cooperating with the projections.
  • a preferred configuration of the projections are lands extending between a series of transversely extending grooves along the upper surface of the outsole.
  • the positioning mechanism may also preferably include a pair of longitudinally extending grooves on either side of the transversely extending grooves, and an upwardly extending side wall.
  • the impact responsiveness of the fluid-filled insert is thus attained more directly than if a foam material were interposed between the outsole and the fluid-filled insert. Furthermore, since the fluid-filled insert is secured in position by the positioning mechanism on the outsole, foam material is not required for this function.
  • the fluid-filled insert thus can occupy a major portion of the volume of the sole structure in the area where the insert is located, thereby dominating the impact response of the sole structure in that area.
  • the outsole is formed as an integral one-piece outsole, and a section of the outsole is formed of a clear material.
  • the clear material preferably extends along the bottom and around a portion of two sides of the sole structure. In this manner, the bottom and both sides of the midsole surrounded by the clear section of the outsole are visible.
  • the visible section of the midsole is preferably the fluid-filled insert which is thus visible over a 180° extent.
  • the fluid-filled insert is also preferably formed of a flexible fluid-containing wall made of a clear material. Visibility over this broad area is accomplished by utilizing a single-piece integral outsole with a clear section of material, and not by forming an aperture in the sole structure, which tends to weaken the sole structure and limit the area of visibility.
  • Shoe 10 includes a sole structure 12 and an upper 14 attached thereto.
  • Upper 14 can be of any conventional design, while sole structure 12 incorporates the features of the present invention.
  • Sole structure 12 includes a force absorbing or cushioning midsole 16 and a flexible, wear resistant outsole 18.
  • Midsole 16 includes an inner member or insert 20 and an outer member 22.
  • Outsole 18 is preferably made of a conventional solid natural or synthetic rubber with a density typically greater than 1.
  • the material of outsole 18 should have a hardness greater than that of a typical prior art foam midsole, and should also be abrasion resistant.
  • Outsole 18 is also relatively thinner, e.g., one-quarter inch or less, than a typical cushioning midsole in the heel area, which can have a thickness between one-half and one inch. While the construction of shoe 10 is shown as that of a typical running shoe, sole structure 12 could be used with other types of shoes, for example, tennis, basketball or walking shoes.
  • Outer member 22 is formed of a cushioning foam material and extends over the upper surface of outsole 18 in the area where insert 20 is not located. As seen in Figure 4, the foam material of outer member 22 extends over only the top surface of insert 20 and fills In valleys or grooves 27 along the top surface.
  • insert 20 has a sealed perimeter and is inflated with a fluid, preferably gaseous, medium, thereby being compliant and resilient. Insert 20 is thus preferably a fluid-filled insert. Insert 20 has an upper surface 24, a lower surface 26, side surfaces 28, 30, a front surface 32 and a back surface 34 all spaced from one another when insert 20 is inflated. Upper surface 24 is connected to the lower surface 26 at preselected areas 41 within the perimeter of insert 20, which when inflated with gas takes on the configuration illustrated in Figure 3, wherein a plurality of chambers are formed.
  • the chambers include lengthwise or longitudinally extending tubes 21, 23 adjacent each of the lateral and medial sides, with transverse tubes 25 connecting the longitudinal tubes. Positioned between the transverse tubes 25 are grooves 27, the base of which is defined by connection areas 41. The function of grooves 27 will be more fully explained herein below.
  • insert 20 is formed of a material as disclosed in U.S. Patent Nos. 4,183,156 and 4,219,945 to Marion F. Rudy and the gas that fills the insert is selected from the group of gases likewise mentioned in the Rudy patents, the disclosures of which are hereby incorporated by reference.
  • the wall material of the insert can be selected from the following materials: polyurethane, polyester elastomer, fluoroelastomer, chlorinated polyethylene, polyvinyl chloride; chlorosulfonated polyethylene, polyethylene/ethylene vinyl acetate copolymer, neoprene, butadiene acrylonitrile rubber, butadiene styrene rubber, ethylene propylene polymer, natural rubber, high strength silicone rubber, low density polyethylene, adduct rubber, sulfide rubber, methyl rubber, thermo-plastic rubbers.
  • Gases also as disclosed in the Rudy patent, which have been found to be usable in the pressure retention within the chambers are as follows: hexafluoroethane, sulfur hexafluoride, perfluoropropane, perfluorobutane, perfluoropentane, perfluorohexane, perfluoroheptane, octafluorocyclobutane, perfluorocyclobutane, hexafluoropropylene, tetrafluoromethane, monochloropentafluoroethane, 1,2-dichlorotetrafluoroethane, 1,1,2 trichloro-1,2,2 trifluoroethane, chlorotrifluoroethylene, bromotrifluoromethane, and monochlorotrifluoromethane. These gases may be termed supergases.
  • the two most desirable gases for use in the insert are hexafluorolethane and sulfur hexafluoride.
  • foam materials are used to make up the balance of the midsole 16, i.e., outer member 22.
  • foam materials also as disclosed in the Rudy patents, include the following: polyether urethane, polyester urethane, ethylene-vinylacetate/polyethylene copolymer, polyester elastomer (Hytrel), ethylenevinylacetate/polypropylene copolymer, polyethylene, polypropylene, neoprene, natural rubber, dacron/polyester, polyvinylchloride, thermoplastic rubbers, nitrile rubber, butyl rubber, sulfide rubber, polyvinyl acetate, methyl rubber, buna N., buna S., polystyrene, ethylene propylene, polybutadiene, polypropylene, silicone rubber.
  • the most satisfactory of the above-identified elastic foam materials are the polyurethane, ethylenevinylacetate/polyethylene copolymer, ethylene vinylacetate/polypropylene copolymer, neoprene and polyester.
  • Outsole 18 is provided with an outer surface having a series of tractive elements 15 positioned thereon, Figures 1 and 2, and on the upper surface having a series of transverse recesses or grooves 17 and transverse projections or lands 19 positioned between the grooves 17, Figures 3 and 4.
  • a pair of lengthwise or longitudinally extending grooves 13 are formed on the outer sides of the upper surface of the sole and connect with the transverse extending grooves 17.
  • These grooves 13, 17 and lands 19 correspond in shape to the outer surface of tubes 21, 23 and 25 and grooves 27 created along the bottom surface of insert 20 when it is inflated with a gaseous medium.
  • Two sidewalls 11, designed to cooperate with fluid-filled insert 20, extend from the upper side surfaces of outsole 18.
  • Sidewalls 11, thus, have interior surfaces which correspond or mate with the exterior surfaces of the longitudinal sides of insert 20 along tubes 21 and 23.
  • the combination of sidewalls 11, grooves 13 and 17 and lands 19 allows insert 20 to be firmly secured in sole structure 12 without surrounding substantially all of the insert with an encapsulating foam material. Only a small amount of foam material 22 covers the top surface of insert 20.
  • the size of insert 20, as a portion of the overall height and width, i.e., volume, of the areas of sole structure 12 within which it is located, can thus be maximized.
  • insert 20 in its area of maximum thickness along tubes 25 occupies greater than approximately eighty percent (80%) of the overall thickness of sole structure 12.
  • Insert 20 should, at its maximum thickness, occupy at least fifty percent (50%) of the overall thickness of the sole structure, and preferably eighty percent or more.
  • insert 20 should occupy greater than fifty percent (50%) of the volume of sole structure 12 in the area of insert 20, and preferably eighty percent (80%) or greater of the volume. In this manner, the insert 20 will dominate the impact response of the sole structure over the entire area in which it is located.
  • sole structure 23 relates to maximizing the visibility of insert 20 through outsole 18. This is accomplished by forming sidewalls 11 and at least the bottom portion of outsole 18 which extends between sidewalls 11 of a clear (either transparent or translucent) elastomeric material. The remaining portion of outsole 18 could also be made of the clear elastomeric material, however, it is preferred to form the remaining portion of an opaque elastomer.
  • the demarcation of opaque sections 51 and 53 of outsole 18 from clear section 55 is indicated by curved lines 47 and 49 at the front and rear edges of clear section 55. Since clear section 55 extends around both the sides and bottom of insert 20, it can be viewed over a 180° extent.
  • Insert 20 is preferably formed of a clear material (e.g. transparent) polyurethane, so that the insert can also be viewed through. Foam material 22 in valleys 27 is thus visible from the bottom and sides of sole structure 12 through the clear materials of outsole section 55 and insert 20.
  • Clear section 55 of outsole 18 is formed as part of a single-piece integral outsole with the surrounding opaque sections 51, 53. This is accomplished by curing the clear and opaque elastomers in a mold at the same time. The clear and opaque, uncured elastomers are placed in a mold at the proper locations and then heated and cured in the mold. A thermal bond is thus formed between the sections 55 and sections 51,53.
  • Figure 4 diagrammatically illustrates the thermal bond between the opaque and clear sections. A blending of the materials forming sections 51 and 55 is shown on the left of Figure 4, while a blending of the materials of sections 53 and 55 is shown on the right of Figure 4.
  • Clear section 55 can be formed from any elastomeric material that can be formulated to provide a clear product.
  • This clear elastomer can be based on either thermoplastic or thermosetting resin systems. Thermosetting systems are generally preferred because of compatibility of processing techniques and better physical properties.
  • Suitable elastomeric material include synthetic elastomers based on homo and copolymer systems such as polycondensation polymers (e.g. polyurethanes), ethylene-propylene based copolymers (e.g. EPDM) other synthetic rubber materials, (e.g. SBR, neoprene etc.) vinyl-based polymers (e.g. poly vinyl chloride), polyacrylate copolymers and the like.
  • the preferred class of clear elastomeric materials is polyurethanes which can be cured for example by peroxide curing systems.
  • Preferred polyurethane materials include millable polyurethanes such as MILLATHANE 88 (a polyether-based polyurethane available from TSE Industries).
  • a clear elastomeric material will be guided by the need to provide (1) compatibility with the opaque materials, i.e. ability to bond to each other and (2) acceptable physical properties of the final sole material.
  • the clear elastomer should possess properties that approximate those of conventional opaque soling materials, e.g. good flexibility, durability, abrasion resistance, traction and the like.
  • the clear elastomeric material should be formulated to provide resistance to discoloration by oxidation or UV light.
  • a preferred elastomic composition suitable for use according to this invention may include conventional additives such as fillers, UV light stabilizers, antioxidants, curing agents and the like. In general, additives which do not adversely effect the clear nature or physical properties of the elastomeric material can be used.
