Definitions

  • the present invention relates to improvements in resilient, all-surface soles that are applied to or or are integral part of footwear. More specifically, it relates to improvements in such soles as described, illustrated and claimed in my U.S. Pat. No. 5,634,283, which was issued on Jun. 3, 1997.
  • Gold shoe normally have soles with metal spikes or studs that extend at right angles to the bottom surface of the sole, so that when the golf shoes are worn on sod, the spikes readily penetrate the sod to a depth such that, when the golfer exerts downward pressure on the shoe sole, the footwear remains in a fixed position relative to the sod despite substantial torque that is applied by the golfer during his swing.
  • a footwear sole formed from a resilient material such as rubber and having a plurality of metal studs mounted in the sole, each stud or spike having an anchoring poortion embedded in the resilient sole, a tip portion extending outwardly from the sole surface, and a shaft portion joining the tip and the anchor of the stud.
  • the studs will extend outwardly from the sole a distance sufficient to enable the wearer to obtain purchase on that softer surface due to penetration of the studs into the surface.
  • the sole comprises utilizing studs that have an anchoring portion interior of the sole and adapting that portion of the sole that engages the anchoring portion of the stud to the specific conditions toward which the stud is designed.
  • the resilience of the rubber will vary through the depth of the sole as that depth is measured from the bottom, work-contacting surface of the sole to that sole surface that contacts the upper of the footwear.
  • the sole is formed so that the resilience thereof varies between the bottom and upper surfaces of the sole. Such variation can be uniform, that is, more resilient at the bottom, work-contacting surface of the sole and least resilient at the portion of the sole that contact the shoe upper.
  • the sole is formed from layers of rubber, a more resilient zone being located at the bottom of the sole and even at the uppermost zone, with a less resilient, i.e., harder zone being formed at a central location to lend stability to the shoe..
  • the more resilient zone can be located between the two, harder zones of rubber.
  • another embodiment of my invention is based on the formation of a groove in the bottom, work contacting surface of the sole.
  • Such groove is annular in shape and surrounds the tip of a stud that projects from the bottom surface.
  • the stud has a degree of resilience, itself, the groove permits the stud to flex to the side when excess pressure is directed against it, rather than have the additional pressure on the study force the stud into a hard underlying surface which it will then tend to scar.
  • the soles can be formed in a single molding operation in which the resilient material, such as natural or synthetic rubber, has its composition varied from one surface of the sheet from which the soles are formed to the other surface.
  • the sole can be molded from individual sheets. For example, two sheets of less resilient and one sheet or more resilient can be formed and cut to size, and the more resilient layer sandwiched between the harder layers and molded to them. Production efficiencies may determine which methods of forming the desired structures prove more effective.
  • FIG. 1 is a perspective view generally showing the exterior of footwear having an all-surface sole according to my invention
  • FIG. 2 is an enlarged sectional view illustrating the sole construction according to one preferred embodiment of my invention
  • FIG. 3 is an enlarge sectional view illustrating another preferred embodiment of a sole construction according to my invention.
  • FIG. 4 is an enlarged sectional view of a third, preferred embodiment
  • FIG. 5 is another section illustrating a variant of the embodiment of FIG. 4, and
  • FIG. 6 is still another sectional view showing a variation that comprises a combination of previously illustrated preferred embodiments.
  • Sole 10 may be permanently attached to shoe 11 or may be removable therefrom and placed, either with another, similar sole after excessive wear, or with another sole that has different characteristics.
  • sole 10 has a bottom, work-contacting surface 12 , from which protrude a plurality of metal studs 13 .
  • the upper surface 14 of the sole is not seen in FIG. 1, but lies in juxtaposition to the upper of the shoe 11 .
  • the pattern in which the studs 13 are arranged is predetermined and is not considered to be part of the present invention.
  • each stud 13 is formed with an anchoring portion 15 , a tip portio 16 , and a cylindrical or conical shank or shaft portion 17 so that it will remain substantially in place in relation to the resilient material of the sole in which it is encased.
  • the tip 16 may be of a variety of shapes so long as its function of engaging a surface on which the wearer of the footwear 11 places it is maintained.
  • the tip portion 16 is shown as cylindrical, but may also be conical with the apex of the cone projecting outwardly from the bottom surface 12 of the sole 10 .
  • the shaft 17 serves the function of connecting the tip and anchor of a stud. Indeed, the tip portion may simply be constituted as the extremity of the shaft 18 .
  • Portions of intermediate density lie between the zones 20 and 21 , and are indicated by reference numeral 22 .
  • the density and resilience of the sole 10 decreases from the sole bottom surface 12 to the sole upper surface 14 , and in this embodiment it is preferred that such decrease be uniform in its extent, that is, that the resilience of the sole uniformly increase as one moves from the bottom surface 12 to the upper surface 14 of the sole 10 .
  • the anchoring portion 16 of the stud 13 is embedded in the rubber sole approximately halfway between the bottom and top sole surfaces. In this position the anchor 15 is located at a part of the thickness of the sole that is of lesser density and greater resilience than that portion 20 adjoining bottom surface 12 .
  • the stud 13 will be able to be retracted more easily when the user of the footwear 22 steps on a hard surface than if the resilience of the sole were uniform throughout its depth. Yet the hardness of the rubber at the bottom surface of the sole will still be of greater density, and therefore provide greater wear resistance and sturdiness to the footwear. However, retraction of the stud will still be adequate if the wearer of the shoe is of light weight, for example.
  • FIG. 3 shows a different, preferred embodiment.
  • harder rubber layers are disposed adjoining both surfaces of the sole 10 .
  • a relatively hard layer 25 is located at the bottom surface 12 of the sole and, similarly, hard layer 26 is located at the upper surface 14 of the sole.
  • those relatively hard layers have between them a softer, more resilient layer or zone 27 , which in effect is sandwiched between the more dense layers.
  • the reason for the layering of more and less resilient zones in the FIG. 3 embodiment is to enable the stud 13 to be retracted more easily into the sole 10 , while still maintaining a relatively firm sole bottom surface that will resist undue wear.
  • the shaft 17 of stud 13 extends through the less resilient portion 27 and into the more resilient portion 27 , in which the anchor 15 of stud 13 is located.
  • the stud is more readily retractable because it anchor portion 15 is encased within the more resilient zone 17 .
  • the less resilient outer layer 25 adjoining the bottom surface 12 of the sole 10 is in contact with the work, i.e., the surface on which the wearer is striding. In this manner ease of retractability of the stud or spike is enhanced while the wear resistance of the footwear is the same as if the denser bottom layer of the sole extended throughout the entirety of the sole.
  • FIG. 4 of the drawings Still another embodiment of my invention is illustrated in FIG. 4 of the drawings.
  • the sole 30 is formed of a single zone of rubber, and a cleat portion 31 extends downwardly and forms, in part, the bottom surface of the sole.
  • a stud 32 Encased within the body of the sole is a stud 32 , comprised of an anchor 33 and a tip 34 joined by a shaft 35 that extends substantially perpendicular to the horizontal axis of the sole 30 .
  • the groove 37 that surrounds the tip and forms an annular opening about the tip 34 and in this case a lower portion of the shaft 35 .
  • the shaft of the stud 32 is usually formed from metal, providing such an annular recess 37 enables some flexing of the stud when it contacts a hard surface, and such flexing permits unwanted scarification of that surface in addition to the resilience imparted by the stud anchor 33 embedded in the resilient sole 30 .
  • FIG. 5 shows another preferring embodiment of my invention that is similar to that of FIG. 4.
  • the sole 40 is formed from two layers of rubber, an upper or inner layer 41 and an outer, work contacting zone or layer 42 .
  • a stud 43 is provided, which stud includes an anchor 44 joined by a shaft 45 to a stud tip 46 .
  • the tip 46 is surrounded by annular recess 47 to permit some flexing of the tip and associated shank 45 .
  • outer layer or zone 42 is of harder, more wear resistance material, while inner layer 41 is more resilient. So, as the anchoring portion 44 of stud 43 is backed by more resilient zone 41 , the stud can be retracted far more easily than if it had to press against the harder, less resilient zone 42 .
  • sole 50 is formed from a relatively hard upper layer 51 of rubber or other material, to which is adhered a relatively resilient layer 52 . Then a cleat 53 formed of relatively hard rubber protrudes downwardly from the resilient layer 52 .
  • the stud 54 extends with its tip 55 in hard layer 53 and shaft 56 passing through that hard layer into zone 52 in which its anchor 57 is encompassed.
  • the stud 54 can be retracted with a fair degree of ease, as its anchor need only compress a part of the more resilient layer 52 while both the work contacting cleat 53 and the upper layer 51 of the sole 50 are formed from a less resilient material adapted to provide great wear resistance and rigidity to the sole in its entirety.
  • the annular recess 57 permits some flexibility of the tip and tip 55 and shaft 56 of the stud 54 .
  • the soles disclosed herein can be made by molding in one piece or, where the sole is formed from layers of materials of difference degrees of resilience, by separately forming each layer and then fusing the layers together.
  • the hardness of the synthetic or natural rubber compounds utilized will vary as set forth in U.S. Pat. No. 5,634,283, from between about 65 to 90 Durometer Shor A. Where greater hardness and less resilience are desired, the sole hardness will be at a maximum, whereas where much more resilience is desired, the Shor Durometer hardness will be at a minimum.
