Definitions

  • THIS INVENTION relates to shoe constructions, and has particular reference to shoes with removable soles that are attached to the shoe body by separable or detachable means such as layers of loop-and-hook material of the type sold under the Trade Mark "Velcro". Such material is herein referred to as loop and hook material'.
  • Prior shoe constructions of this general type are shown in Bauer US Patent No. 4,377,042 in which a flanged sole assembly is interlocked with the shoe body by a combination of loop and hook material and interlocking structural elements, and Einstein US Patent No. 3,538,628 in which a combination of loop and hook material and locking lugs was used. In each of these, the separable connection formed in whole or in part by the loop and hook material permitted the changing of the sole of the shoe.
  • McCord US Patent No. 3,027,661 in which a special-purpose insert was held in a recess in the central portion of a shoe sole by loop and hook material permitting changing of that central portion.
  • Dilg US Patent No. 4,279,083 in which an entire removable sole of substantially the same shape as the underside of the shoe body is held on the body by layers of loop and hook material having perimeters that are contiguous with the perimeter of the underside of the shoe body, providing a simple and secure, yet easily detachable connection for the sole.
  • This invention is an improvement in a shoe construction of the Dilg patent.
  • a shoe construction comprising: a shoe body for fitting around the foot of a wearer; a midsole portion disposed below said shoe body and secured thereto to lie beneath the foot of a wearer; a peripheral rib on said midsole portion extending downwardly therefrom and cooperating with said midsole portion to define a downwardly opening recess; a sole disposed in said recess and having substantially the same shape as the recess to fit closely but removably along said rib, said sole having a body thinner than the depth of said recess and an underside that is substantially flush with the lower end of said rib; and two layers of detachable coupling material disposed in said recess between said sole and said midsole portion; one layer being secured to the upper side of said sole, said layers being releasably coupled together to hold said sole releasably in said recess.
  • the entire removable sole is recessed into the underside of the shoe within the narrow protective rib extending around the perimeter of the underside of the shoe.
  • the rib not only assists in securing the sole to the shoe and protecting the coupling material from the elements, but also conceals the joint from view. The result is believed to be the optimum design for such shoe constructions in terms of simplicity and area of the portion that is removable and security of the detachable connection.
  • the invention is embodied in a shoe 10 of the type having an upper body I composed of soft material such as leather or canvas that is shaped to fit around the foot, a shoe lace 12, and a sole assembly 13 that is attached to the underside of the body to lie under the foot of a wearer (not shown).
  • the illustrative shoe is of a well-known type that is popular for athletic use, in running or a variety of sports, and is shown in Figure I as having a sole 14 that is equipped with conventional lugs or cleats 15 for improving the wearer's footing in a soft running surface.
  • the upper body of the shoe is of conventional construction, and the sole assembly 13 is attached to the body in a conventional fashion, typically being cemented or vulcanized to the body, and sometimes stitched as well.
  • the material of the body is shown in Figure 3 as having lower edge portions which fit into the upper side of the sole assembly and are cemented in place.
  • An insole 18 overlies these edge portions and provides the foot-engaging surface 19 of the sole assembly.
  • the sole assembly 13 has a central midsole portion 20 directly beneath the insole 18 and an outer wall 21 that extends entirely around the perimeter of the shoe body.
  • the upper edge of this wall is an upwardly extending rib that defines an upwardly opening recess 22 in which the shoe body is secured,and the lower edge portion of the wall is a downwardly extending rib that defines a downwardly opening recess 23 in which the sole 14 of the shoe is secured.
  • the midsole portion 20 and the wall 21 are shown as integral parts, typically molded of a suitable flexible material such as rubber or a plastic, the recess 23 being formed in the underside of the moulding and being of approximately the same shape, width and length as the shape, width and length of the shoe body, and having a substantially flat top surface 24 which is the underside of the midsole portion.
  • the removable or outer sole 14 comprises a strip of sole material that is thinner than the depth of the recess 23 by the combined thickness of two layers of loop and hook material 27 and 28, one layer 27 being secured to the top surface 24 of the recess and the other layer 28 being secured to the upper side of the sole 14. These layers are complementary, one carrying a loose pile of fibre loops and the other carrying a pile of hooks which are engageable releasably in the loose pile of fibre loops.
  • This material may be that sold under the Trade Mark"Velcro".
  • An early form of such a material is shown in US Patent No. 2,717,437.
  • One source of this type of material is Minnesota Mining and Manufacturing Company (3M), Minneapolis, Minnesota.
  • the recess has the same peripheral shape as the underside of the shoe body, extending from a rounded "heel” end through a relatively narrow “arch” portion to a wider "ball” portion and a rounded “toe” end, the downwardly extending rib preferably forming a continuous border for the recess along both sides and across both ends.
  • the outer sole 14 has the same shape as the recess, and is only slightly smaller so as to fit closely, but removably, in the recess. When the sole is pressed into place and the two coupling layers 27 and 28 are engaged, the underside of the sole is substantially flush with, or slightly below, the lower end of the rib.
  • the sole 14 is securely held on the midsole portion 20 and is surrounded and protected by the rib which defines the recess 23.
  • the shoe 10 appears to be conventional, and performs much as a conventional shoe performs, yet the sole 14 is removable simply by pulling or prying it out of the recess.
  • the sole 14 is removable simply by pulling or prying it out of the recess.
  • Probably the easiest way to remove it is to insert one finger, or a tool (not shown) between the sole and the upper layer 27 at one of the rounded ends, and pull downward, starting the separation of the coupling layers at a narrow point and then pulling the sole progressively away from the shoe.
  • FIG. 4 Shown in Figure 4 is a second sole 14 1 that is interchangeable with the first sole 14, having a different type of lower surface, herein a ribbed tread of a general-purpose nature.
  • This sole is of the same shape and thickness as the sole 14, and has a layer of loop and hook material 27 1 which covers its upper side, for coupling engagement with the layer 28 in the recess.
  • the sole 14 can be installed on the shoe 10 simply by pressing it into the recess 23.
  • the present invention provides a shoe construction in which a full sole is recessed into the underside of a sole assembly and held releasably therein by complementary loop and hook layers while being protected and masked by the downwardly extending peripheral rib which surrounds the recess.
  • the result is optimum simplification of the removable and interchangeable soles as well as optimum performance of the shoe.
