Definitions
- the present invention relates to the field of footwear.
- the invention concerns, more particularly, an article of footwear having a sole structure that is separable from an upper.
- Conventional articles of athletic footwear generally include two primary elements, an upper and a sole structure.
- the upper is secured to the sole structure and forms a void on the interior of the footwear for securely and comfortably receiving a foot.
- the upper is generally formed from multiple elements that are stitched and adhesively bonded together to form a comfortable structure for receiving the foot.
- Conventional athletic footwear may include, for example, an exterior formed of leather and polymer textile materials that are resistant to abrasion and provide the footwear with a particular aesthetic. Foam materials may be located on the interior of the upper to enhance the comfort of the upper, and moisture- wicking textiles may be positioned adjacent the foot to limit the perspiration within the upper.
- the sole structure attenuates ground reaction forces and absorbs energy as the footwear contacts the ground, and often incorporates multiple layers that are conventionally referred to as a midsole and an outsole.
- the midsole forms the middle layer of the sole and serves a variety of purposes that include controlling potentially harmful foot motions, such as over pronation, and shielding the foot from excessive ground reaction forces.
- the outsole forms the ground-contacting element of footwear and is usually fashioned from a durable, wear resistant material that includes texturing to improve traction.
- the sole structure may also include an insole, which is a thin, cushioning member located within the upper and adjacent to a sole of the foot to enhance footwear comfort.
- sole structures are generally configured for use during specific activities, particularly with athletic footwear.
- a sole structure may incorporate pronation control elements that are beneficial for running, stability elements for court-style activities, or relatively soft cushioning for walking.
- a sole structure that is configured for one athletic activity, such as long-distance running, may not be suitable for use during another athletic activity, such as tennis.
- Each different type of sole structure therefore, requires a distinct upper in footwear where the upper and sole structure are permanently secured together.
- U.S. Patent Number 6,023,857 to Vizy et al. discloses footwear with a permanently attached upper and outsole that includes a separate midsole and heel counter structure, which is removable from the upper.
- U.S. Patent Number 5,083,385 to Halford and U.S. Patent number 4,974,344 to Ching both disclose an outsole structure that is detachable from the remainder of the footwear.
- U.S. Patent Numbers 6,023,859 and 5,799,417 to Burke et al. disclose an article of footwear with removable and exchangeable inserts that are positioned between the upper and a lower portion of the sole structure. The inserts protrude through the lower portion of the sole structure to provide a ground-contacting surface.
- the present invention is an article of footwear having an upper and a sole structure.
- the upper includes an ankle opening and a pair of side portions extending downward from the ankle opening.
- the upper also includes a connection element located opposite the ankle opening and extending between the side portions.
- the connection element forms a bottom portion of the upper and defines an aperture.
- the sole structure includes a foot- supporting element and a projection connected to said foot-supporting element. The sole structure is insertable through the ankle opening such that the foot-supporting element is positioned adjacent an upper surface of the connection element and the projection extends through the aperture to provide a ground-contacting surface.
- the footwear configuration described above provides separability between the upper and the sole structure. That is, the upper and sole structure may be separated into two discrete components of the footwear. During use, however, the upper and sole structure are intended to remain securely connected.
- a locking system may be incorporated into the footwear.
- the locking system includes an indentation in the projection that receives an edge of the aperture, thereby effectively securing the upper to the sole structure.
- the indentation may be positioned, for example, adjacent the foot-supporting element.
- the footwear may also include additional features, including an outsole section and a textile liner.
- the sole structure may include a polymer foam, particularly in the projection.
- the outsole section which may be formed of a rubber material, may be positioned on a lower surface of the projection to enhance the abrasion-resistance and durability of the sole structure.
- the foot-supporting element may be formed of a polymer foam material.
- a textile liner may be secured to the upper surface of the foot-supporting member.
- Figure 1 is a lateral elevational view of an article of footwear having a separable upper and sole structure in accordance with the present invention.
- Figure 2 is an exploded elevational view of the footwear.
- Figure 3 is a perspective view of a bottom and medial side of the footwear.
- Figure 4 is an exploded perspective view of the footwear.
- Figure 5 is a cross-sectional view of the footwear, as defined by line 5-5 in Figure 1.
- Figure 6 is a bottom plan view of the footwear.
- Figure 7 is a bottom plan view of the sole structure.
- Figure 8 is a bottom plan view of the upper.
- Figure 9 is a lateral elevational view of the article of footwear with an alternate locking system.
- Figure 10 is a cross-sectional view of the footwear with the alternate locking system, as defined by line 10-10 in Figure 9.
- upper 20 and sole structure 30 are separable.
- This structure provides a plurality of advantages over the conventional, non-separable footwear.
- upper 20 and sole structure 30 may be separately cleansed in a manner that best suits the respective materials forming each component. If one of upper 20 and sole structure 30 becomes worn or otherwise damaged, the damaged component may be replaced without the necessity of replacing the undamaged component.
- upper 20 and sole structure 30 may be interchanged with alternate uppers or sole structures to suit a particular activity or a preference of an individual.
- footwear 10 is divided into a heel portion 11, a midfoot portion 12, and a forefoot portion 13, as defined in Figure 1.
- Heel portion 11 generally corresponds with the area of footwear 10 that receives the heel and ankle of the individual
- midfoot portion 12 generally corresponds with the area of footwear 10 that receives the arch
- forefoot portion 13 generally corresponds with the area of footwear 10 that receives the toes.
- Portions 11-13 are not intended to demarcate precise areas of footwear 10. Rather, portions 11-13 are intended to encompass general areas of footwear 10 to aid in the following discussion.
- Upper 20 incorporates a plurality of elements that are stitched or otherwise connected to form a comfortable structure for receiving the foot.
- Each element may include an individual material or selected textile, foam, leather, and polymer materials that are stitched or adhesively bonded together.
- the textile materials for example may include a mesh cloth that provides enhanced air-permeability and moisture- wicking properties.
- the foam materials may be a lightweight thermoset foam that conforms to the shape of the foot and enhances the comfort of footwear 10.
- the leather and polymer materials may be positioned in high-wear portions of upper 20, or in portions of upper 20 that require additional stretch-resistance or support. Accordingly, upper 20 may be manufactured from generally conventional materials.
- the various elements forming upper 20 define a lateral side 21a, an opposite medial side 21b, an ankle opening 22, and a connecting element 23.
- Lateral side 21a and medial side 21b generally cover the sides, heel, and instep portion of the foot and may include laces or another tightening system for tightening upper 20 around the foot and securing the foot within footwear 10.
- Lateral side 21a and medial side 21b define ankle opening 22 and extend downward from ankle opening 22 to join with connecting element 23.
- Ankle opening 22 provides access to a void within upper 20 that accommodates both sole structure 30 and the foot.
- Upper 20 is, therefore, configured to receive sole structure 30 and the foot through ankle opening 22.
- Lateral side 21a, medial side 21b, and ankle opening 22 have, therefore, a generally conventional configuration.
- upper 20 includes connecting element 23, which is secured to lateral side 21a and medial side 21b and extends across a bottom of upper 20 to form a lower surface of upper 20.
- Connecting element 23 is secured to a lower portion of lateral side 21a and medial side 21b to form a lower surface of upper 20.
- a variety of attachment techniques may be utilized for securing connecting element 23 to lateral side 21a and medial side 21b, including stitching, adhesive bonding, thermobonding, or a combination of stitching and bonding, for example.
- Connecting element 23 extends onto a toe area of lateral side 21a and medial side 21b in forefoot portion 13. This configuration limits forward movement of the foot relative to footwear 10.
- Connecting element 23 may also extend upward on the lateral side, on the medial side, or in heel portion 11.
- Connecting element 23 may be a single element, as depicted in Figure 5 and 8, or a plurality of elements that are joined together.
- the primary purpose of connecting element 23 is to form a plurality of apertures 24a-24g in a lower surface of upper 20.
- Suitable materials for connecting element 23 include a plurality of flexible and mildly stretchable polymers, including polyether block amide, thermoplastic polyurethane, or a variety of rubber or elastomeric materials. A combination of materials may also be utilized.
- a majority of connecting element 23 may be formed from a textile or leather material, and a polymer may be secured to the textile or leather around each of apertures 24a-24g.
- Sole structure 30 is separable from upper 20 by disengaging sole structure 30 from upper 20 and drawing sole structure 30 through ankle opening 22, thereby removing sole structure 30 from the void formed within upper 20.
- the primary elements of sole structure 30 are a foot-supporting element 31 and a plurality of projections 32a-32g.
- Foot-supporting element 31 extends from heel portion 11 to forefoot portion 13 and provides an upper surface for contacting and supporting the foot.
- the upper surface of foot-supporting element 31 may be contoured to include a depression in heel portion 11 for seating the heel; an arch in midfoot portion 12 for supporting the arch; and an area in forefoot portion 13 for supporting forward portions of the foot, including the toes.
- foot-supporting element 31 may be raised to form a general depression in the upper surface of foot-supporting member 31, thereby providing an area for securely receiving the foot.
- a textile liner 33 may be attached, through adhesive bonding for example, to the upper surface of foot-supporting element 31.
- a lower surface of foot-supporting element 31 contacts connecting element 23 when sole structure 30 is received by the void within upper 20.
- projections 32a-32g extend through apertures 24a-24g, respectively, and extend downward from upper 20 to form a ground-contacting portion of footwear 10.
- Each projection 32a-32g includes one of a plurality of outsole sections 34a-34g that impart a durable and abrasion-resistant lower surface to projections 32a-32g.
- Suitable materials for outsole sections 34a-34g include any of the various rubber materials that are conventionally utilized in footwear outsoles, including blown rubber, carbon rubber or a combination of blown and carbon rubbers.
- sole structure 30 is formed of a polymer foam material that provides cushioning as footwear 10 contacts the ground. More specifically, sole structure 30 acts to attenuate ground reaction forces and absorb energy as sole structure 30 is compressed between the foot and the ground. This may occur, for example, during activities that involve walking or running. Suitable materials for sole structure 30 are, therefore, any of the conventional polymer foams that are utilized in the midsoles of athletic footwear, such as ethylvinylacetate and polyurethane foam. Sole structure 30 may also incorporate a fluid-filled bladder in heel portion 11 or along the entire length of foot-supporting element 31 in order to provide additional cushioning, as disclosed in U.S.
- Projections 32a-32g may have a variety of shapes within the scope of the present invention, including circular, elliptical, triangular, hexagonal, square, or any other geometrical or non-geometrical shape. As depicted in Figure 7, projections 32a-32g each have different non-geometrical shapes and are distributed throughout footwear 10. More specifically, projections 32a-32b are positioned in forefoot portion 13, projections 32c- 32e are positioned in midfoot portion 12, and projections 32f-32g are positioned in heel portion 11. Similarly, projections 32a, 32c, 32e, and 32f are positioned on a lateral side of footwear 10, and projections 32b, 32d, and 32g are positioned on a medial side of footwear 10.
- projections 32a-32g extend downward and through apertures 24a-24g, respectively.
- the shapes of projections 32a-32g generally correspond with the shapes of apertures 24a-24g to provide a secure connection between connecting element 23 and sole structure 30.
- the secure connection ensures, for example, that sole structure 30 remains properly positioned relative to upper 20 during walking, running, or other ambulatory activities.
- the secure connection also ensures that dirt, stones, twigs and other debris do not enter upper 20 through apertures 24a-24g.
- apertures 24a-24g may be formed to have an area that is slightly smaller than the area of projections 32a-32g.
- Apertures 24a- 24g may stretch, therefore, when receiving projections 32a-32g. Furthermore, projections 32a-32g may each define one of an indentation 35a-35g that extends at least partially around projections 32a-32g. Indentations 35a-35g may be utilized to receive the edges of apertures 24a-24g, thereby forming a locking system that securely connects sole structure 30 to upper 20.
- the area of engagement between apertures 24a-24g and projections 32a-32g, which includes indentation 35a-35g, may have approximately the same area as apertures 24a-24g, or a slightly greater area to ensure a secure connection.
- edges of apertures 24a-24g and indentations 35a-35g form the locking system that securely connects sole structure 30 to upper 20.
- a secure connection is generally formed when the edges of apertures 24a-24g extend into indentations 35a-35g.
- the connection may be enhanced, however, when the shape of the edges of apertures 24a-24g generally correspond with the shape of indentations 35a-35g.
- the edges of apertures 24f and 24g have a shape that corresponds with and engages the surfaces of indentations 35f and 35g. That is, the edges of apertures 24f and 24g have a generally convex shape that engages a generally concave shape formed by the surfaces of indentations 35f and 35g.
- apertures 24a-24g and indentations 35a-35g may be structured to form other corresponding shapes.
- the indentations may be formed in the edges of apertures 24a-24g and projections 32a-32g may form protrusions that mate with the indentation in the edges of apertures 24a-24g.
- Indentations 35a-35g may extend entirely around each of projection 32a-32g. As depicted in the figures, however, indentations 35a-35g extend only partially around each of projections 32a-32g. More specifically, indentations 35a-35g are located only on portions of projections 32a-32g that face outward from footwear 10. With respect to projection 32c, for example, indentation 35c is positioned on the lateral side of projection 32c and extends at least partially onto front and rear portions of projection 32c. Indentation 35c is not located, however, on the medial side of projection 32c.
- Indentations 35a-35g receive the edges of apertures 24a-24g to form a locking system that securely connects sole structure 30 to upper 20.
- the edges of apertures 24a-24g extend into indentations 35a-35g, and the shape of the edges of apertures 24a-24g generally correspond with the shape of indentations 35a-35g.
- the edge of apertures 24a-24g may have a rounded configuration, as depicted in Figure 5, in order to increase the surface area of contact between connecting element 23 and sole structure 30.
- upper 20 may include a series of tubular structures 25 that extend around connection element 23, and sole structure 30 may include a series of corresponding tubular structures 36 that align with tubular structures 25 of upper 20 and fit between tubular structures 25.
- Various pins 37 could be placed through tubular structures 25 and 36 to secure upper 20 and sole structure 30 together.
- upper 20 and sole structure 30 have corresponding tubular structures 25 and 36 that are similar to the configuration of a hinge, with pins 37 serving the purpose of the pin in the hinge structure.
- the structure of footwear 10 described above provides a variety of advantages over conventional footwear, wherein the sole is permanently attached to the upper.
- some individuals may prefer a sole structure that limits the degree to which the foot pronates upon contact with the ground.
- the same individual may prefer a sole structure that exhibits a high degree of stability during court-style activities, such as basketball or tennis.
- the individual may acquire a single upper 20 and multiple sole structures 30, each sole structure 30 being suitable for different activities. The individual may then select one of the multiple sole structures 30 for use with upper 20. Similarly, the individual may acquire multiple uppers 20 for use with a single sole structure 30.
- Upper 20 and sole structure 30 are formed from different materials. Whereas a large portion of upper 20 includes textiles, sole structure 30 is primarily formed from polymer foam and rubber. Upper 20 and sole structure 30 may benefit, therefore, from cleansing techniques that are specifically suited to their respective materials. Accordingly, upper 20 may be separated from sole structure 30 and each may be cleansed in an appropriate manner.
- Outsole sections 34a-34g are formed of a rubber material to provide durable, ground- contacting elements of footwear 10. Although outsole sections 34a-34g are abrasion- resistant, significant use of footwear 10 may eventually wear through portions of outsole sections 34a-34g. Rather than dispose of footwear 10, sole structure 30 may be properly recycled and replaced with an alternate sole structure 30, thus extending the lifespan of footwear 10. Similar considerations apply to upper 20.
- upper 20 and sole structure 30 also provides the individual with the ability to customize the appearance of footwear 10.
- footwear 10 may be purchased to have an upper 20 and sole structure 30 with substantially similar colors.
- the color combination of footwear 10 maybe customized to the preferences of the individual.
- Support for a particular athletic team, for example, may also be demonstrated by selecting upper 20 and sole structure 30 combinations that reflect the colors of the athletic team.
