Definitions

  • the present invention relates to improvements in shoe soles and, more particularly, improvements in replaceable shoe soles for athletic shoes.
  • modern athletic shoes are constructed so as to be extremely comfortable and to provide a large degree of support for those portions of the foot and ankle which experience great stress while participating in certain sports. This improvement in the construction of the athletic shoes has encouraged participation in athletics and exercise by many participants.
  • specialized athletic shoes have also been constructed for use in particular sports. For example, one can easily find shoes which have been specially constructed and engineered for use in sprinting, jogging, basketball, racquetball, soccer, etc.
  • Existing shoes with replaceable soles typically are comprised of an upper shoe portion, or "upper”, having a bottom surface or “mid-sole”.
  • a replaceable sole is provided with a substantially continuous ridge which is snapped or press fitted into a matching, deformably resilient groove recessed into the mid-sole.
  • the ridge is comprised of a leading edge portion or head which is undercut to form a narrower neck.
  • the neck attaches the ridge to the upper surface of the replaceable shoe sole.
  • the groove recessed into the mid-sole is also substantially continuous and has a cross-sectional shape generally the same as that of the ridge.
  • the width of the opening of the groove Is approximately the same as the width of the neck of the ridge.
  • the opening is formed by a pair of protrusions which are resilient and deformable such that they permit the head of the ridge to pass through the opening and yet are sufficiently rigid to act as retention means for the ridge. These protrusions cooperate with the undercut portions of the ridge to hold
  • the present invention comprises improvements in replaceable shoe soles for athletic shoes, walking shoes, work shoes, and the like.
  • the present invention comprises a projection formed on the upper surface of the replaceable shoe sole which removably mates with a cavity formed in the mid-sole. This configuration is designed to permit the shoe to withstand lateral and twisting forces, rather than mere removal forces which would cause the ridge to be removed from the groove.
  • these projections and mating cavities can be placed in the ball area of the shoe where the sole may experience the greatest stresses.
  • a similar projection may also be placed at the heel for use in sports such as golf where the twisting action of the golf shoe places particular stress at that location.
  • the projection and mating cavities can also be placed in the center section of the shoe in order to provide additional support. Since retention of the replaceable sole on the mid-sole is accomplished by means of a ridge and groove, the fit between the projection and cavity need not be one of close tolerance.
  • the projection may be undercut slightly in order to provide good retention means within the cavity and to prevent any shifting. In the heel projection, the bending of the shoe causes a distortion in
  • the heel projection is constructed so as to be slightly shorter than the length of the matching cavity to accommodate this elongation.
  • the thickness of the replaceable shoe sole in its center portion can be reduced so that, during bending, the stretching or elongation will occur in this portion and will not occur at the heel. This will maintain the dimensional integrity of the projections at both the toe and the heel while still accommodating changes in dimension at the center portion of the sole.
  • the present invention also comprises a starting area for this replacement.
  • a starting area for this replacement In this aspect of the present invention, one or both sides of the groove in a limited area are removed. In other words, one or both of the projections which form the opening of the groove are removed for a short distance so that the groove opening is widened.
  • arrows or other small indication means are placed on the side of the mid-sole indicating where this shaved portion is located.
  • This process also referred to as "walking" provides a method for the step-by-step insertion of the ridge into the groove. In this method of attaching the replaceable shoe sole to the mid-sole, finger pressure is sufficient to manually press-fit the ridge into the matching groove.
  • the present invention also comprises a replaceable toe for athletic shoes where extraordinary wear and tear is experienced at this location of the shoe. This is sometimes due to toe dragging which occurs in the particular activities, such as serving in tennis.
  • the replaceable toe of the present invention is also maintained in place by means of a ridge or other projection on the inner surface of the replaceable toe which mates into a groove or other indentation in the toe of the shoe.
  • the ridge and groove combination of the replaceable toe need not have the same kind of retention capabilities as the sole because of fewer frictional and moment forces acting on the toe.
  • the replaceable toe can also be provided with a lower flange which overlaps the replaceable shoe sole, thus assisting in maintaining its position on the mid-sole of the shoe.
  • the concepts and principles of the present invention also comprise a snow travelling device which can be utilized as a snow shoe or, alternatively, a cross-country type ski.
  • a snow travelling device which can be utilized as a snow shoe or, alternatively, a cross-country type ski.
  • the bottom surface of a boot or other shoe is provided with a groove similar in construction and configuration to the groove described above.
  • a base member is likewise provided with a matching ridge for attachment to the sole of the boot.
  • This base member can be provided with attachments, such as snow shoe webbing, or cross-country ski devices, in order to permit its use as a snow travelling device.
  • the base member is provided with a flexible or hinged heel which permits the heel lifting action utilized in walking or travelling in snow shoes or cross-country skis. This flexible heel acts as a hinged binding.

  • Also formed in the mid-sole 12 is one or more cavities, such as the cavity shown near the ball or toe of the shoe ("ball cavity 18"), the cavity in the center section of the mid-sole 12 (“center cavity 20") and the cavity near the heel (“heel cavity 22").
  • FIGURE 2 illustrates the top surface 24 of a replaceable shoe sole 26 having a ridge 28 formed thereon in substantially the same configuration as the groove 16 of the mid-sole 12. Also shown on the top surface 24 of the sole 26 is a ball projection 29 which has substantially the same configuration as the matching ball cavity 18 formed in the mid-sole. The ball projection 29 is located toward the toe of the sole where the greatest weight of the wearer is concentrated. The precise location of the ball projection 29 will vary with the sport, but may correspond to the ball or toe of the foot. If.desired, similar projections 30 and 32 can be formed in the center of the sole and near the heel, as shown in FIGURE 5, to match the center and heel cavities 20 and 22, respectively, of the mid-sole 12.

  • FIGURE 3 This figure illustrates, in cross section, the ridge 28 inserted into the groove 16 of matching configuration.
  • the ridge is provided with a beveled leading edge 27 to facilitate insertion into the opinion 38 of the groove 16.
  • the ridge 28 is undercut so as to form a relatively large head 34 attached to the top surface 24 of the sole 26 by means of a relatively narrower neck 36.
  • the groove 16 is provided with a narrow opening 38 formed by means of protrusions 40 on either side.
  • a retentive force is created which resists forces tending to remove the sole from the mid-sole.
  • This retentive force is supplied by the relative rigidity of the protrusions 40 which form the groove opening 38 and their positioning adjacent the undercut head ' 34 of the ridge 28.
  • the ridge 28 can be removed so that the sole 26 can be replaced.
  • the bottom surface 41 of the replaceable sole can be provided with traction devices 42, such as those shown in FIGURE 4, or with the cleats, such as the golf cleats 44 shown in FIGURE 6, to provide a very versatile shoe with interchangeable soles.

  • these soles 26 can be easily replaced.
  • the ridge/groove interconnection illustrated in FIGURE 3 is sufficient to firmly retain the replaceable shoe sole 26 on the mid-sole 12 under most conditions. Such conditions include the removal forces acting substantially vertical to the ground. However, it has also been found that a certain lateral or twisting forces which are exerted on the sole can also cause it to wholly or partially become removed from the groove. For example, in sports such as tennis and racquetball, lateral motion is very common. During such lateral motion, the weight of the body of the wearer is shifted from side to side so that all the holding or retentive strength of the sole must be supplied by one of the longitudinal edges 43 (FIGURES 1&2) of the ridge/groove interconnection.
  • the opposite edge may be lifted from the ground or may be carrying very little weight.
  • the neck 36 and head 34 of the ridge 28 may elongate due to this lateral stress, and the protrusions 40 forming the opening 38 of the groove 16 may become distorted outwardly, thus causing the opening to widen.
  • the ridge 28 tends to be removed from the groove 16 and interconnection is lost.
  • the toe or heel portion of the shoe is twisted, thus, exerting a torque or twisting force on the sole. Again, all of the holding force must be supplied by one concentrated area of the ridge/groove interconnection.
  • the projection/cavity interconnection 39 of the present invention shown in FIGURE 4 provides additional retentive force to withstand these lateral and twisting forces.
  • the projection/cavity 39 interaction causes the lateral forces to be distributed more broadly across the sole/mid-sole interface.

  • the ball projection 29 is preferably undercut slightly so as to provide a snug fit within the corresponding cavity 18 on the mid-sole 12.
  • this interconnection does not provide the same kind of retentive force against substantially vertical removal forces as does the ridge/groove interconnection described above.
  • the purpose of the projection/cavity interconnection is to provide additional resistance to lateral and twisting forces and to maintain the ridge 28 firmly in position within the groove 16.
  • the projection 29 need not be undercut.
  • the ball projection 29 is rounded slightly in the direction of the toe so as to distribute the holding force more broadly in that area.
  • FIGURE 8 illustrates in partial cross-section the projection/cavity interconnection near the heel of the replaceable sole 26 while the sole is experiencing bending, usually at the center section.
  • the heel projection 32 is preferably slightly shorter than its corresponding cavity 22.
  • the bending of the sole 26 causes the heel projection 32 to elongate and move in the direction of the arrow because of the larger radius it experiences. Thus, allowance must be made in the cavity 22 to provide for this elongation.
  • the purpose of the heel projection 32 is to resist removal forces that are caused by lateral or twisting forces.
  • the heel projection is generally rectangular to conform with the shape of the heel, permitting it to distribute its retentive force over a wide area at the heel.
  • FIGURE 8a is a partial cross-sectional view illustrating a portion of the groove in which the protrusions on both sides have been removed.
  • This cross- section refers to a starting area 46 indicated in FIGURE 4 for facilitating insertion of the ridge 28 within the groove 16.

  • the head 34 of the ridge 28 is easily inserted into the groove 16 since it does not have to be forced in the small opening 38 between two protrusions 40.
  • only a single protrusion 40 in the starting location 46 can be shaved slightly to permit insertion of the ridge 28.
  • the starting location 46 is found in the center section of the mid-sole 12 since this section sees a minimum amount of removal for us.
  • the adjacent head portion of the ridge 28 causes the adjacent groove area to widen because of the partial insertion of the head 34 in the opening.

  • the ridge 28 mounted on the replaceable shoe sole 26 may be removed from the groove 16 due to large removal forces. This occurs when lateral or twisting forces cause the protrusions which form the opening of the groove to be distorted, thus widening the opening and permitting the ridge to be removed. This is particularly true in cross-country skiing or snow shoeing in which vertical removal forces are very high and where the security of the interconnection between the ridge and groove is important. However, the interconnection must be capable of being broken in the event that the wearer falls. If the cross-country ski or snow shoe does not become removed from the boot or shoe of the wearer, serious injury could result. Thus, it is desirable that a secure interconnection be maintained without an unremovable locking situation so as to avoid injury to the wearer.
  • This dual-clamping device 78 reinforces the walls of the groove 80 to minimize distortion of the groove opening, thus maintaining a secure, but removable interconnection between the ridge 72 and of the base plate 66 and the groove 80 of the boot 77.

Abstract

Une semelle remplaçable pour chaussures de sport, de travail, de ville et similaires, comprend une interconnexion à dentelures/rainures qui permet de remplacer la semelle lorsque celle-ci est usée ou endommagée. La dentelure rétrécie à la base s'accouple à une rainure dont la section transversale a une configuration correspondante afin de donner la force de retenue nécessaire pour maintenir la semelle remplaçable dans une position adjacente à la semelle intérieure de la chaussure. Quelques améliorations comprennent l'utilisation de protubérances et de cavités correspondantes adjacentes à l'interconnexion à dentelures/rainures afin de fournir une force supplémentaire de retenue résistant aux tensions latérales et aux torsions exercées sur la semelle remplaçable pendant son utilisation. En outre, la rainure est pourvue d'une zone initiale pour faciliter l'attachement et le remplacement de la semelle. Un bout renforcé remplaçable peut également être fixé par une interconnexion semblable à dentelures/rainures, et un dispositif de serrage fournit une force supplémentaire de retenue.
