Definitions

  • This invention is in the field of athletic shoes which provide a cushioning effect on the feet during motions such as walking, jumping, and running.
  • At least one shoe manufacturer produces a shoe which has inflatable chambers actuated by a push-button pump. These chambers are inflated in anticipation of strenuous activity and deflated after completion thereof.
  • the chambers are filled only to the level which will provide the proper amount of support for the intended activity and thus provide the advantage of variable support.
  • the present invention is an improved sole construction for an athletic shoe which not only provides cushioning for the foot of the wearer, but also provides a high degree of energy return or rebound to the wearer of the shoe.
  • the shoe includes a first sole portion having spaced cleats extending therefrom and a second sole portion having correspondingly spaced apertures for receiving the cleats.
  • Resilient means are held between the first and second sole portions at least partially covering the apertures and cooperable with the cleats for normally maintaining the first and second sole portions spaced apart with the cleats of the first sole portion aligned with the receiving apertures of the second sole portion.
  • Cleat guide means restricts lateral relative movement of the first and second sole portions to maintain alignment of the cleats with the apertures and to stabilize the shoe during athletic activities.
  • Means interconnect the first and second sole portions and a shoe upper for receiving a wearer's foot is secured to one of the sole portions while a ground-contacting receiving surface is secured to the other sole portion.
  • the shoe in one embodiment, includes a top sole portion with downwardly extending cleats and a substantially coextensive bottom sole portion with apertures corresponding to the cleats so as to receive therein the cleats of the top sole portion.
  • a resilient membrane i positioned and held between the top and bottom sole portion to normally maintain such top and bottom sole portions in spaced apart, rest configuration wherein the cleats of the to sole portion are held by the membrane above and in alignmen with the receiving apertures of the bottom sole portion.
  • Whe force is applied to the sole of the shoe, such as by a perso standing, walking, running, jumping, or landing in the shoe, the force is absorbed by the membrane as the cleats of the top sole portion move into the receiving recesses of the botto sole portion, with the membrane stretching therebetween.
  • the membrane urges the top and bottom sole portions apart to their normal rest positions wherein the membrane is unstretched.
  • the membrane is force responsive and stretches in response to the force applied, to thereby effectively cushion and support the foot of the wearer.
  • the resilient membrane stores energy as it is stretched under force and returns that energy as the force is removed, thus providing a high degree of rebound to the shoe.
  • An important feature of this arrangement in accordance with the present invention is a guide plate having cleat- receiving openings and being interposed between the top sole portion and the resilient membrane being substantially coextensive therewith, and with the cleats positioned in the cleat receiving openings of the guide plate to insure effective operation by reason of maintaining the cleats substantially centered relative to the apertures of the bottom sole portion and by restricting lateral relative movement between the two sole portions.
  • the membrane is coextensive with the bottom sole portion and is secured to the bottom sole portion by gluing it thereto and is secured to the top sole portion by screws extending through the membrane into selected cleats. In this way, the top and bottom sole portions are interconnected through the membrane.
  • the cleat-guide plate is preferab glued to the top of the membrane so that the membrane i sandwiched between such guide plate and the bottom sol portion.
  • a flexible side cover is provided about the perimeter o the sole portions to close the space therebetween and preven foreign matter, such as rocks, from becoming lodged betwee the top and bottom sole portions to interfere with prope operation of the shoe.
  • This side cover may be secured onl around the perimeter of the top sole portion, hanging freel therefrom as an apron or skirt so that the bottom sole portio is free to move up and down in relation to the cover, or th cover may be flexible and attached around the perimeter o both the top sole portion and bottom sole portion so the sid cover will flex and bend to allow relative movement of the to and bottom sole portions.
  • a perimetrical closure strip of flexible and preferably elastomeric material may be sealingly interposed between the apron or skirt and the sole to completely seal the sole against entry of foreign matter.
  • the perimetrical side cover secured to the top sole portion and the bottom sole portion serves as the means interconnecting the sole portions.
  • top sole is usually the cleated one as described above, the arrangement of the parts can be reversed with operation remaining essentially the same.
  • the characteristics of the membrane may be varied over various parts of the sole so that different support and cushioning properties are provided over different parts of the sole and therefore, different parts of a wearer's foot.
  • individual membranes may be provided associated with each of the apertures. This makes it easy to vary the characteristics of the membrane over different parts of the sole since a membrane of desired characteristics can be individually provided for each aperture.
  • the individual membranes may be held between the first and second sole portions by a carrier or holding means which also serves as the cleat guide means.
  • the membrane may take the form of 0-rings or other elastic bands positioned in the apertrues to cooperate with the cleats.
  • O-rings are supported by aperture shoulder means and interact with shoulder means on the cleats.

  • the athletic shoe of the invention comprises a top sole portion 10, a bottom sole portion 12, a resilient membrane 14 between top sole 10 and bottom sole 12, a cleat guide plate 15, a sheet of ground- contacting wearing surface material 16, and a standard shoe upper 18.
  • the top sole portion 10 is preferably made of a hard rubber or plastic material and includes a plurality of downwardly-extending cleats 20.
  • Bottom sole portion 12 is constructed of a polyurethane microcellular plastic or other suitable elastomer material and has the same parametric shape as top sole portion 10.
  • Bottom sole portion 12 includes apertures 22 in numbers equal to the number of cleats 20 of the upper sole portion 10, each aperture 22 being sized, shaped, and located to correspond to and receive a cleat 20 of top sole portion 10 therein as covered by stretched portions of membrane 14. As shown in Figs. 1-7 the cleats 20 are cylindrical and peg-like, while receiving apertures 22 in bottom sole portion 12 are cylindrical holes.
  • Resilient membrane 14 which may be gum rubber, surgical rubber, or other suitable resilient material, is preferably secured to the top of bottom sole portion 12, as by gluing, covering the cleat-receiving apertures.
  • the cleats 20 re on top of membrane 14 and in this embodiment in which the so portions are not interconnected by the side closure of t shoe, membrane 14 is secured to selected cleats 20 by scre 24, Figs. 2, 6, and 7, which extend through such membrane into the selected cleats.
  • Fig 1-7 it has been found that a total of five such screws 24 a sufficient to effectively connect the top sole portion 10 membrane 14. Since membrane 14 is attached to bottom so portion 12 in this embodiment, top sole portion 10 connected to bottom sole portion 12 through membrane 14.
  • a guide plate (which may be relatively thin and semi-rigid) is plac between the membrane and the cleated sole portion, preferab being secured to the membrane by gluing. Accordingly, as he shown, membrane 14 is sandwiched between bottom sole porti 12 and guide plate 15. Guide plate 15 has apertures or clea receiving openings 26, Figs. 3 and 4, which are aligned wit and correspond to apertures 22 in bottom sole portion 12, an in which the cleats 20 are positioned. Generally, th apertures 26 in guide plate 15 will be smaller than aperture 22 in bottom sole portion 12 so that cleats 20 fit relativel closely, as shown in Figs. 3 and 4.
  • any type of shoe upper 18 may be secured to top sol portion 10 in manner well known to the shoe manufacturin industry, and layers of padding 28 and 30, Figs. 3, 6 and 7, may be provided (as is normal) to cushion the sole and confor it to the shape of the bottom of the wearer's foot.
  • the sho upper may be either low top or high top and may be made of variety of materials such as leather, canvas, or a synthetic. Further, the shoe upper may be of lace type as shown in Fig. 1, may have Velcro or other fasteners, or may merely be o slip-on type.
  • FIGs. 4, 5, and 7 show the maximum displacement of the cleats into the apertures.
  • the membrane will be chosen so that maximum displacement will not occur under expected forces to be applied to the shoe, and displacement will be less than the maximum and dependent upon the force applied. Thus, when a wearer jumps and lands, more force is applied than during normal standing or walking and more stretching or displacement of the membrane occurs. Also, the displacement will not generally be uniform along the length and width of the shoe, uniform displacement being shown in Fig. 7 merely for purposes of illustration but will vary depending upon the activity During walking or running, when weight is initially placed o the heel at the beginning of a step, the displacement wil occur in the area of the heel, with little or no displacemen in the area of the toe.
  • the specific characteristics of the membrane may be varied for different parts of the sole so, for example, the membrane over the heel part may be less stretchable than the member over the toe part and thus require more force to displace a cleat into the aperture a given distance for the heel part than for the toe part.
  • the thickness of the bottom sole portion, and thus the depth of the apertures be slightly greater than the length of the cleats so the cleats do not extend through the aperture to the ground surface. It is also preferred that the bottom of the bottom sole portion have a layer of ground-contacting material 16, such as the rubber material normally used on the bottom of athletic shoes. While the additional layer of ground- contacting material is preferred, in some instances the bottom sole portion itself could be made to serve as the ground- contacting material.
  • a side cover 40, Figs. 3, 6, and 7, of apron or skirt formation is preferably provided extending about the perimeter of the top sole portion and bottom sole portion to cover the space between the two to prevent foreign objects, such as pebbles, dirt, etc., from entering the space and interfering with the relative movement of the two. Also, it adds to the aesthetics of the shoe.
  • This apron or skirt 40 is in the form of a strip of rubber or plastic material secured, as by gluing, around the perimeter of the top sole portion and extending freely downwardly to the upper perimeter of the bottom sole portion to cover the space between the top and bottom sole portions when in the normal rest portion, as shown in Figs. 3 and 6.
  • apron or skirt 40 is not secured to bottom sole portion 12, so such bottom sole portion 12 is free to slide up and down in relation to apron or skirt 40 as indicated in Fig. 7 relative to Fig. 6, but, with such an apron or skirt, it is preferable to utilize the embodiment of Fig. 18 as described hereinafter.
  • the side cover can take the form of a strip 42, Fig. 5, which is secured, as by gluing, to the perimeter of both the top sole portion and the bottom sole portion and is flexible enough to flex outwardly as shown in Fig. 5 as the top and bottom sole portions move toward one another.
  • the side cover since the side cover interconnects the top and bottom sole portions, in some embodiments, it is not necessary to use the screws 24.
  • cleats 20 and receiving apertures 22 have been shown in Figs. 1-7 as cylindrical, various shapes of cleats and receiving apertures may be used.
  • Figs. 8 and 9 show a second embodiment of the invention wherein the cleats 50 and receiving apertures 52 are elongate rather than cylindrical in form, and extend from side-to-side of the shoe. As illustrated. Fig. 8, in this embodiment the receiving apertures 52 do not extend completely through the bottom sol portion 54, but leave a thin portion 56 at the bottom of eac aperture so that the bottom sole portion remains in one piec for ease of assembly. Holes 58 allow access to screws 6 which correspond to the screws 24 in the previous embodiment.
  • Fig. 10 shows a third alternate embodiment for the cleats, with elongate cleats 62 extending only partially across the cleated sole portion.
  • the size of the cleats may vary.
  • the length of the heel area cleats may be longer to give a larger range of stretch and force adsorption than the cleats of the toe area which generally are subject to less force.
  • a membrane of natural gum rubber has been found satisfactory for general use such as walking and running.
  • wide variations in the characteristics of the membrane may be desirable, depending upon the intended use of the shoe and the intended wearer.
  • various means of connecting the top and bottom sole portions to the membrane can be used.
  • the embodiment of the invention shown in Figs. 11-13 includes a support plate 64, which confronts the bottom of resilient membrane 66 and is apertured to receive the cleats 68 of top sole portion 70 covered, as they will be, by the stretched portions of membrane 66.
  • support plate 64 protects the margins of bottom sole portion 72 surrounding the respective apertures 74 thereof, against spalling off or wearing away under pressure of the membrane. Also, support plate 64 will generally be of a harder or more rigid material than is bottom sole portion 72 so that the edges of support plate 64 around aperture 74 do not deform substantially. Therefore, particularly when membrane 66 is secured to plate
  • plate 64 such as by gluing over the entire surface of plate 64, plate 64 will limit the portion of membrane 66 which stretches in response to movement of cleats 68 to only that portion of the membrane extending over an aperture 74.

Abstract

Une chaussure de sport, pourvue d'une semelle sensible à une force exercée sur elle, comprend une première partie de semelle (110) comportant plusieurs barrettes (20) faisant saillie à partir de cette dernière, et une seconde partie de semelle (12) pourvue d'ouvertures correspondantes (22) servant à loger les barrettes (20). Une membrane élastique (14) est placée entre les parties de semelle, et recouvre les ouvertures (22) afin de séparer les barrettes (20) et les ouvertures (22) en position de repos. Une plaque de guidage (15) à ouvertures correspondantes est placée entre la première partie de semelle (10) et la membrane (14), les barrettes se positionnant dans les ouvertures de cette plaque afin de limiter tout mouvement transversal d'une partie de semelle (10, 12) par rapport à l'autre et de maintenir les barrettes en alignement avec les ouvertures (22). Lorsqu'une force est appliquée par un pied, la première partie de semelle (10), comportant les barrettes, se déplace vers la seconde partie de semelle (12), munie d'ouvertures, ce qui étire la membrane (14) alors que les barrettes (30) pénètrent dans les ouvertures (22) de la seconde partie de semelle (12), la membrane (14) opposant alors une résistance à ce mouvement de façon à produire un effet d'amortissement ainsi qu'une force de rebondissement.
