Definitions

  • the present invention relates to an apparatus for providing adaptive grip on a variety of surfaces.
  • the invention has particular although not exclusive relevance to cleats or studs provided on the sole of footwear such as football boots.
  • studs on the sole of each shoe to increase the ability of the user to grip the surface whether the user is trying to remain still or move.
  • the term studs used throughout this application applies to all protrusions from the sole of the shoe or boot which may be circular, wedged shaped, spikes, etc., which function to increase traction between the user and the ground. In some countries, such studs are commonly referred to as cleats.
  • a user generally selects the length, size, pattern, shape, number and distribution of such studs in accordance with the ground conditions in which the footwear is to be used. The most common arrangements are
  • trainer grip The choice relies on the user making an accurate assessment of the ground conditions and requires the user to have several pairs or shoes available. To eliminate the requirement for multiple pairs of shoes, it is also known in the art to vary the length of the studs prior to usage by adjusting a plate underneath the sole. However, both of these methods require a choice to be made prior to usage and are based on the average ground conditions.
  • footwear users are sometimes injured due to excessive lateral forces applied to the lower leg. This situation, occurs during a user's normal activities such as, for example, suddenly changing direction.
  • the present invention aims to address one or more of these problems and to provide an alternative grip/stud assembly for the sole of a shoe.
  • the present invention provides a stud assembly having a rocking member coupled to a stud which is spring biassed to act against forces transmitted through the stud during use.
  • the present invention provides a stud assembly having a primary stud and at least one secondary stud, wherein force applied to the primary stud causes the secondary stud to be engaged towards the ground.

Two of the stud assemblies 3-1 and 3-2 are provided at the heel of the sole 5 whilst the remaining four stud assemblies 3-3 to 3-6 are provided at the front of the sole 5. As shown in Figure 1, each stud assembly 3 comprises a primary stud 7 and two smaller secondary studs 9 and 11 on either side of the primary stud 7. In this embodiment, each of the stud assemblies 3 is arranged so that the three studs
  • the three studs are attached to a spring plate 15-1 to 15-6 shown in phantom in Figure 1.
  • an inner edge of the spring plate 15 is moulded and attached to the sole 5 whilst the outer edge (on which the three studs are mounted) is free to flex to allow relative movement between the primary stud 7 and the secondary studs 9 and 11.
  • this relative movement allows the football boot to vary the traction provided to the user under varying ground conditions.
  • the spring plate 15 acts to distribute impact forces experienced by the user during use over a larger area of the sole 5, thereby reducing the likelihood of injury to the user. Further advantages of the stud assemblies 3 will become apparent from the following detailed description.
  • Figure 2A illustrates in more detail the components of one of the stud assemblies 3.
  • the primary stud 7 has a generally cylindrical shape with a circular cross-section and has a snap-on barbed end 21 for engagement with the hole 23 on the spring plate 15.

  • the holes 23, 25 and 27 for receiving the studs 7, 9 and 11 respectively are arranged along the longer edge 29 of the spring plate 15.
  • the stud assembly 3 is then formed by snap fitting the barbed ends 21 of the primary stud 7 and the secondary studs 9 and 11 into the respective receiving holes 23, 25 and 27.
  • the spring plate 15 also includes two additional holes 31 and 33 provided at the narrower edge 35 of the spring plate 15. As will be described in more detail below, these help to anchor the spring plate 15 into the sole 5.

  • a liquid plastic is then poured into the mould and allowed to solidify around the stud assemblies 3 to form the sole 5 of the football boot.
  • Figure 2B shows part of the resulting sole 5 having the stud assembly 3 embedded into a section thereof.
  • the mould tool used in the moulding process is arranged so that each stud assembly 3 is only attached to the sole 5 at the narrower edge 35 thereof and along four strip sections (two of which are shown and labelled 41 and 43) which extend across each stud assembly 3 on either side thereof.
  • the two strip sections which are not shown in Figure 2B and which are provided below the stud assembly 3 act as fulcrums about which the spring plate 15 can flex.
  • the two upper strips 41 and 43 are provided for holding the stud assembly 3 within the sole 5.
  • FIG. 2B As shown in Figure 2B after the first moulding operation, spaces 45a, 45b and 45c are provided around each of the studs. These spaces are then filled in a second moulding operation with an elastomer which provides a water-tight seal around the primary stud 7 and the secondary studs 9 and 11.
  • Figure 2C illustrates the elastomer 47 which is formed within the spaces 45 shown in Figure 2B.
  • FIG. 2D a piece of resilient foam 49 is inserted into a space 51 provided underneath the primary stud 7 on the inside surface of the sole 5 that is attached to the rest of the football boot 1.
  • Figure 2D also shows the other two strips 53 and 55 discussed above about which the spring plate 15 flexes during use.

  • the primary stud 7 penetrates the surface 63 of the soft ground, with the force of the impact being transmitted along the primary stud 7 to the spring plate 15 and then along the strips 53 and 55 to the sole 5 of the shoe where the force is then transmitted to the user's foot.
  • Some of the force impact is also absorbed by the elastomer 47 and the foam 49 formed in the sole 5. In this way, the force transmitted through the primary stud 7 is not transmitted directly to the user's foot but is distributed over a larger area around the primary stud 7 , which reduces strain on the user's foot which in turn can reduce long term injuries.
  • the primary stud 7 When the user is on hard ground, the primary stud 7 will not penetrate (or will do so to a lesser extent) the surface 63 of the ground 61.
  • the impact force therefore causes the spring plate 15 to deform away from its normal shape allowing the primary stud 7 to move towards and into the resilient foam member 49.
  • Figure 3B when the spring plate 15 deforms it flexes as the portions around the strips 53 and 55 rotate about the strips 53 and 55. As a result, some of the impact force is absorbed by the spring plate 15 and the resilient foam member 49, thereby reducing the impact force transmitted through to the user's foot.
  • Figure 4 is a cross-sectional view of stud assembly 3-5 along the line y-y shown in Figure 1.

  • the portion of the stud assembly 3 around the primary stud 7 forms a spring board which, in addition to providing cushioning for forces applied perpendicular to the ground through the stud 7, also provides some resistance to lateral forces applied to the stud 7 parallel the ground.
  • each stud assembly 103-1 to 103-4 includes a primary stud 107 and two secondary studs 109 and 111. As shown in Figure 6, these studs are received in and attached to a respective spring member 115-1, 115-2, 115-3 and 115-4.
  • spring members 115-2 and 115-3 are connected together to form a single composite spring member which holds the studs of the respective assemblies.
  • spring members 115-1 and 115-4 are also connected together to form a composite spring member for holding the corresponding studs.
  • the stud assemblies also include a respective flexible plastic cover portion 147-1 to 147-4 which protect the metal spring plates 115 and which prevent the ingress of water and dirt ingress.
  • these plastic cover members 147 extend through a rigid plastic outer sole 150 which attaches to the sole 105 to hold the components of the stud assembly in place.
  • the sole 105 includes, for each stud assembly, a pair of fulcrum blocks 153 and 155 about which the spring member 115 can rotate.

  • the spring member 115 is arranged so that when assembled in the sole, an inside limb 161 is fixed to the sole 105 whilst the outer limbs 163 are free to move relative to the sole 105.
  • impact forces applied to the primary studs 107 are transmitted through to the outer limbs 163 of the spring plates 115 which cause them to move (rotate) towards the sole 105 against the fulcrum blocks 153 and 155.
  • This movement also causes the outer edges 165 to flexibly rotate away from the sole 105 thereby causing the secondary studs 109 and 111 to move away from the sole 105 and to engage with the ground.

  • the stud assembly may be used in a hiking boot, such as the one shown in Figure 7, where the secondary studs are spikes which are arranged to engage with the ground when the user is on hard ground such as ice.
  • a planar spring plate was used as part of the stud assembly. As those skilled in the art will appreciate, it is not essential to have a spring member that is exactly planar. The edges of the spring member may be bent inwards towards the sole or outwards away from the sole in order to vary the amount of movement of the studs located on these edge portions towards and away from the sole.

  • Figure 10A illustrates the stud assembly 503 when no force is applied to the primary stud 507. However, in use, when an impact force is applied to the primary stud 507, the stud bearing portion 525 rotates about the pivot points 521 and 523 compressing the elastic block 527. As a result, the primary stud 507 moves towards the sole 505 and the secondary studs 509 and 511 move away from the sole 505 towards the ground. When the impact force is removed, the compressed elastic block 527 expands and pushes against the stud bearing portion 525 returning the stud assembly to its original position shown in Figure 10A.

Abstract

La présente invention se rapporte à une semelle de chaussure et à un ensemble de crampons qui sont tels que lesdits crampons sont montés sur un élément élastique de la semelle, procurant ainsi à l'utilisateur un effet d'amortissement en cours d'utilisation. Dans un mode d'utilisation préféré, l'élément élastique (15-5) comprend au moins un crampon primaire (7-5) et un ou plusieurs crampons secondaires (9-5, 11-5) qui sont conçus pour entrer en contact avec le sol lorsqu'une force de choc provoque la déformation du crampon primaire en direction de la semelle de la chaussure. De cette manière, il est possible d'obtenir une adhérence supplémentaire sur divers états de surface.
