Definitions

  • the present invention relates to a studded shoe and a stud for a studded shoe.
  • Studded shoes which are in particular used for football, primarily have to provide good grip with a soft ground such as lawn. To this end, studded shoes are equipped with studs which penetrate the ground and prevent slipping of the studded shoe across the ground.
  • Rotationally symmetric studs have been known for this purpose for a long time. When such a stud penetrates the ground, the movement of the studded shoe is completely stopped within a fraction of a second. This causes enormous ground reaction forces which act on the body and in particular on the feet of the player. The ground reaction forces arise in particular during changes of the direction of movement and/or the speed and depend on the softness of the ground. They may lead to an early exhaustion of joints and muscles and may in the worst case cause injuries. Measurements in other sports such as basketball and tennis have shown that for example side cuts may cause forces in transversal directions of up to 1000 N.
  • DE 23 13 646 describes screw-in studs having various damping elements and springs which enable an elastic movement of the stud vertical to the sole as well as in transversal direction and in tangential direction.
  • EP 0 356 637 A1 further relates to a sports shoe whose outsole comprises integrally formed lobes with a deformable ring body.
  • the elastic material of the deformable ring body enables a deflection of the lobe.
  • rotationally symmetric studs do not provide a secure grip of the studded shoe in the ground in all situations, in particular in connection with rotary motions. In an extreme situation, for example during a direction change, there may be only a single stud penetrating the ground while rotary forces act on the studded shoe. A rotationally symmetric stud does not provide resistance against these rotary forces so that the studded shoe turns and the player may not be able to perform the intended change of directions, and he may even lose his/her balance.
  • asymmetric studs have been developed which provide increased resistance against rotary forces on the studded shoe and whose shape is in particular adjusted to the strains arising in football.
  • DE 198 50 449 B4 of applicant describes such a stud which has an elongate shape and which can effectively prevent turning of the shoe in the ground.
  • Asymmetric studs i.e. studs which do not have a rotationally symmetric shape but which have, for example, an elongate shape which is optimized for the respective purpose are also known in other sports.
  • US 5,377,431 and US 5,505,012 describe studs which are deformed, laterally deflected or translated in transversal direction when lateral forces act on the shoe in transversal direction of the sole.
  • US 5,617,653 relates to studs which are releasably coupled to the base assembly in response to lateral forces for reducing injuries.
  • US 5,361,518 describes a shoe with a damping element between sole and stud.
  • the stud is both axially moveable and slightly tiltable laterally without being able to rotate.
  • the above-described studded shoes have the disadvantage that the moveability of the stud consists primarily in that the stud is moveable vertically with respect to the sole or can be deflected from its axis which is vertical to the sole. This contributes little to damping horizontal ground reaction forces which act parallel to the ground and which are insufficiently dampened by tilting or axial movement of a stud.
  • the rotationally symmetric stud described in fig. 4 of DE 2 313 646 is intended to enable elastic translations, rotations and tilt; however, according to the description these movements are only small and therefore enable only insufficient damping.
  • the stud described in US 5,377,431 and US 5,505,012 is limited in that the stud is only moveable in a transversal direction of the sole.
  • Document ES 2117548 discloses movable studs for sports footwear. It consists in incorporating a metal female part (4) provided with an internally hollow emergent rod (3), provided or not with a helical thread, which will emerge through a reinforcing area (8) provided with an opening (8') having a cavity or recess inside the sole in which the female part (4) is incorporated, in cooperation with two side fixing parts (6) and (6'), or else in a sole provided with circular reinforcements (11) having a cross-like opening (11') which enable multidirectional movements, in cooperation with fixing parts (5) provided with bores (5') in the case of the multidirectional parts, along with an external coupling of a protecting part (12) carrying a bore (12') through which the threaded or non-threaded rods of the studs extend, or else with the cooperation of an elongated part (9), in the bidirectional embodiment, provided with a central bore (9'); and acting in the same way as the part (12) as an anchorage protection.
  • the present invention is therefore based on the problem to provide a studded shoe and a stud which not only provide good grip with the ground but which also dampen the ground reaction forces resulting therefrom to prevent injuries more effectively than the solutions known from the prior art.
  • the present invention solves this problem according to a first aspect with a studded shoe having at least one stud, wherein the at least one stud has an asymmetric shape which is able to provide in use and if the stud is inserted into the ground resistance against rotary motions of the studded shoe with respect to the ground.
  • the at least one stud is attached to the studded shoe so that it can perform translatory and rotary motions with respect to a first surface determined by a sole.
  • the claimed studded shoe comprises at least one asymmetric stud which is dampened against linear and rotational ground reaction forces by performing translatory motions or rotary motions or both with respect to the first surface.
  • Translatory motions of the stud alone provide protection against linear ground reaction forces.
  • they provide partial protection against rotational ground reaction forces whose rotation axis is located away from the rotational axis of the stud, more particularly against the linear portion of these forces.
  • rotary motions of the stud provide protection against rotational ground reaction forces, and particularly advantageous is a combination of translatory and rotary motions which provide protection against arbitrarily combined linear and rotational ground reaction forces.
  • the studded shoe therefore not only provides a good grip with the ground during various movements, but also protection against overstraining or injuries to bones and muscles which are caused by suddenly stopping these movements during contact with the ground.
  • the moveability of the stud with respect to the first surface can be implemented in different ways which are described in the following. Generally, in all cases a plurality of studs can move independently of each other and thereby react to the ground forces.
  • the first surface in which the translatory and rotary motions of the stud are performed is flat. This enables a simple and cost-effective mechanical design of the moveable stud.
  • the first surface with respect to which the translatory and rotary motions of the stud are performed is curved. This facilitates adjustment of the movement of the stud to a curved sole so that a stud which has moved maintains its orientation with respect to the sole. This supports the advantageous effect of a curved sole, i.e. to enable an easier rolling-up of the foot during running or walking.
  • the stud performs the translatory motion both in a first dimension as well as in a second dimension independent therefrom. This enables damping of the ground reaction forces in all directions of the first surface and therefore provides comprehensive protection for the wearer of the studded shoe.
  • a dimension is understood to be a degree of freedom of motion. A two-dimensional motion therefore provides motions in all directions within a plane.
  • a translatory motion in the first dimension and a translatory motion in the second dimension are limited, and it is particularly preferred that they are limited differently. This allows an adaptation to specific requirements. For example, a deflection of the stud in transversal direction of the sole may be larger than in the longitudinal direction of the sole.
  • the at least one stud is adapted to perform the rotary motion in a first rotary direction and in a second rotary direction independent of the first rotary direction.
  • the rotary movement in the first rotary direction and the rotary movement in the second rotary direction are limited to different extents. This enables a flexible adjustment of the requirements for various sequences of movement both with respect to damping (stud rotates) as well as a secure grip with the ground (rotary motion is stopped).
  • the translatory motions and / or the rotary motions of the at least one stud is blocked in an initial state in a blocking direction.
  • This provides additional possibilities for adaptation. For example, it may not be desirable that the stud moves in running direction of the studded shoe since this leads to damping of the acceleration forces during a fast sprint. This problem can be solved by blocking a translatory motion of the stud in running direction.
  • the at least one stud comprises an attachment device having a second surface. It is further preferred that the first surface is arranged at the sole of the studded shoe and that the second surface engages behind the first surface. In a further embodiment, the second surface does not engage behind the first surface but is arranged between the stud and the first surface.
  • This solution enables a secure attachment of the stud to the studded shoe since the second surface of the attachment device engages the first surface of the sole.
  • the stud and the second surface of the attachment device of the stud "clamp" the first surface of the sole between the stud and the second surface and thereby enable a robust attachment of the stud to the first surface.
  • this attachment enables two-dimensional movements of the stud with respect to the sole. This solves the problem that an asymmetric stud (in contrast to a rotationally symmetric stud) has to have a particular orientation while enabling rotary motions. This problem cannot be solved by a simple screw-in stud.
  • the second surface is slideably arranged on the first surface. This provides a secure and solid guidance for the movements of the stud.
  • the attachment device of the at least one stud extends through an opening in the first surface. This provides a particularly solid attachment of the at least one stud to the first surface by centrally fixing the stud through the opening. Further, different shapes of the attachment device and the opening limit movements of the second surface with respect to the first surface and thereby limit movements of the stud with respect to the sole of the studded shoe. By varying the shapes of the opening and of (the cross section of) the attachment device, various limitations of the movement of the stud can be realized.
  • the opening of the first surface and a cross section of the attachment device comprise an oblong shape. This limits the rotary motions of the stud. In contrast, a circular shape of the cross section of the attachment device would not limit rotary motions of the stud.
  • the studded shoe comprises a damping element which is connected to the studded shoe and the at least one stud.
  • Such a damping element fulfils several functions.
  • the stud is elastically fixed with respect to the sole of the studded shoe and thereby provides an initial position of the stud. Further, the damping element provides a restoring force towards the initial position and in addition an elastic connection of the studded shoe and the stud.
  • the damping element is arranged on an outside of the first surface.
  • the outside is the side (e.g. a surface) which is turned towards the ground and which is simultaneously the side turned away from the foot of the wearer of the shoe.
  • This arrangement of the damping element provides in a particularly simple way a connection between the stud and the sole of the studded shoe, so that the damping element not only provides a restoring force, but simultaneously can be used as a seal between the stud and the sole of the studded shoe. In this way, the damping element effectively prevents the intrusion of moisture and dirt into the stud of the studded shoe.
  • the damping element has a spring constant in the range of 60 to 90 N/mm, preferably about 75 N/mm, i.e., the damping element exerts a corresponding restoring force during a specific deflection of the stud. Measurements performed in the laboratories of applicant have shown that this range is particularly advantageous.
  • the present invention relates to a stud for a studded shoe having a stud receptacle, wherein the stud receptacle comprises a first surface.
  • the stud has an asymmetric shape which is able to provide in use and if the stud is inserted into the ground resistance against rotary motions of the studded shoe with respect to a ground surface.
  • the stud comprises an attachment device to which a second surface can be attached, wherein the second surface is formed so as to enable a translational and a rotary motion with respect to the first surface.
  • This stud provides a good grip with the ground both with linear and rotary motions of the studded shoe and dampens the ground reaction forces resulting therefrom more effectively than the solutions known from the prior art.
  • Such a stud can be manufactured independently from the studded shoe for use either as a replacement part (to replace a broken or damaged stud), or it can be used as an exchangeable stud having a different functional property such as a different shape from the original stud. This applies also to the following stud.
  • the present invention relates to a stud for a studded shoe, wherein the stud has an asymmetric shape which is able to provide in use and if the stud is inserted into the ground resistance against rotary motions of the studded shoe with respect to a ground surface.
  • the stud comprises a first surface for attachment to the studded shoe and a second surface. The second surface is adapted to perform translational and rotary motions with respect to the first surface.
  • the present invention is not limited to use in football shoes.
  • the described studded shoe may be advantageously used in other sports and outdoor activities, including for example handball, rugby, American football, baseball, hockey, trekking, hiking and mountain climbing since it provides a good grip with the ground during both linear and rotary motions of the studded shoe and dampens the ground reaction forces resulting therefrom. Further applications could be use in protective footwear and safety footwear.
  • Fig. 1 shows a bottom view of a sole of a studded shoe having several asymmetric studs 200.
  • An asymmetric stud is understood to be a stud which is not rotationally symmetric.
  • an asymmetric stud may comprise a symmetry axis, for example a mirror symmetry axis along a longitudinal axis.
  • the asymmetric stud illustrated in fig. 1 is elongated and provides resistance against rotary motions of the sole when the stud has penetrated the ground.
  • stud 200 may perform rotary motions with respect to the sole, as indicated in the right part of fig. 1 by arrows.
  • the rotary motions are performed with respect to a surface which is determined by the sole.
  • the rotational axis is essentially orthogonal to the surface of the sole.
  • a rotary motion is meant to be not only a pure rotation but also a rotation together with a linear translation, as explained in the following.
  • stud 200 enables translatory motions in the surface of the sole, as indicated in the left part of fig. 1 by arrows. This dampens ground reaction forces which are caused by linear movements when stud 200 penetrates the ground.
  • FIG. 2 A presently preferred embodiment of an asymmetric stud which is adapted to perform such rotary and / or translatory motions is illustrated in fig. 2 .
  • This figure shows a perspective view of a sole 100 of a studded shoe having multiple asymmetric studs 200, wherein a stud 200 is illustrated in a cross section.
  • stud 200 comprises a stud body 210 which has an asymmetric shape.
  • Stud body 210 may comprise plastic material such as TPU (thermoplastic polyurethane), preferably for a hard ground, or metal or ceramics, preferably for a soft ground.
  • a first attachment device 220 is arranged inside stud body 210, wherein the first attachment device 220 extends below the lower edge of stud body 210 (the lower edge being the edge closest to the sole 100).
  • Studs can be manufactured from TPUs of different hardness. Compositions of TPU with a high fraction of rubber are used for the damping element 300 (see fig. 2 ). In order to provide improved slideability, the surfaces 130, 230 and cover plate 150 (see fig. 7 ) can be coated either with Teflon, or Teflon (PTFE) can be mixed with the TPU. Multi-component injection molding can be used to form and connect together the single parts.
  • a two-part attachment device 220, 240 is preferably manufactured from metal which provides the highest stability of the stud and an improved fastening between attachment devices 220, 240 (see conical shape of attachment device 220).
  • Fig. 2 further shows second surface 230 which extends essentially parallel to sole 100.
  • Second surface 230 is connected to the second attachment device 240 which encloses the first attachment device 220.
  • Both attachment devices 220, 240 form a solid connection and enable a simple modular assembly of the second surface 230 to stud body 210.
  • Fig. 2 further illustrates that the lower edge of stud body 210 and second surface 230 enclose a first surface 130 which is connected to sole 100.
  • the second surface 230 of stud 200 engages behind first surface 130 and thereby enables a particularly robust attachment of stud 200 to sole 100. Further, in this arrangement stud 200 is able to move in a plane determined by the first surface 130 in connection with the second surface 230.
  • stud 200 engages behind the first surface 130 in that the first attachment device 220 and the second attachment device 240 extend through an opening 131 in the first surface 130. This leads to a robust attachment of stud 200 to sole 100.
  • the stud engages behind the first surface in other ways, for example by an alternative connection element for connecting the stud body to the second surface, wherein the alternative connection element partially encloses the first surface.
  • the second surface can be arranged between the first surface and the stud body, wherein the second surface is moveably arranged using appropriate attachment means.
  • these means may comprise a magnetic connection of the first and the second surface which allows the surfaces to shift with respect to each other but not to separate from one another in a direction orthogonal to the surfaces.
  • clip-in mechanisms or a kind of straddling dowel extending through one of the surfaces are conceivable.
  • the moveability of stud 200 is determined by distance 260 between the second attachment device 240 and the surface 130.
  • the moveability of stud 200 can be determined by distance 270 between second surface 230 and sole 100.
  • the moveability of stud 200 is determined by the different shapes of the opening 131 in the first surface 130 and of the second attachment device 240 (i.e. the cross section along the first surface 130).
  • opening 131 and a cross section of the second attachment device 240 have an oblong shape. This enables a limitation of rotary motions of stud 200.
  • a circular shape of the cross section of the second attachment device 240 would not limit rotary motions of stud 200.
  • the described arrangements enable not only translatory motions, i.e. linear motions, of stud 200 in two independent dimensions, but in addition also rotary motions, wherein the rotational axis of the rotary motions is essentially vertical to sole 100.
  • the first surface 130 and the second surface 230 are flat and thereby lead to a corresponding planar movement of stud 200.
  • the first surface 130 and the second surface 230 are curved and lead to a correspondingly curved movement of stud 200.
  • the movement of stud 200 therefore follows the curved surface and can adapt to complex movements which include, for example, tilting of the studded shoe with respect to the ground and a corresponding tilting of the stud. Thereby the stud remains essentially vertical to the ground and provides optimal ground contact.
  • curved surfaces provide an adaptation of the movement of the stud to a curved sole so that a stud which has shifted its position maintains its vertical orientation with respect to the sole. This provides the advantageous effect of a curved sole which enables easier rolling-up of the foot during running.
  • first surface 130 glides both on the lower side of stud body 210 and on the second surface 230.
  • movement of the surfaces with respect to each other is enabled by other means, for example by a ball-bearing which may in addition be supported by teflon-coating.
  • Fig. 2 further shows a damping element 300 which connects stud body 210 to sole 100.
  • damping element 300 comprises a circumferential first groove 310 which engages a corresponding projection of stud body 210.
  • stud 200 is held in an initial position.
  • damping element 300 is preferably made from an elastic plastic material.
  • a circumferential second groove 330 can be compressed during movements of stud 200 and thereby provides additional play.
  • Establishing an initial position for the stud provides additional possibilities for specific limitations of the movement of stud 200. As described above, distance 260 between the boundary of the first surface 130 and the second attachment device 240 may determine the play of stud 200. By establishing an initial position of stud 200 so that stud 200 touches the first surface 130, movement of stud 200 is blocked in a particular direction (i.e., orthogonal to the boundary of the first surface 130 at the touch point).
  • Fig. 2 further shows that damping element 300 is arranged on the outside of first surface 130, i.e., on the side directed to the outside of sole 100.
  • damping element 300 can fulfil a further important function as a seal between sole 100 and stud 200. This prevents intrusion of moisture and dirt into the bottom side of stud body 210, i.e., the first surface 130 and the second surface 230. This is necessary to ensure that the stud 200 remains moveable.
  • damping element 300 is arranged at the boundary of the first surface 130.
  • fig. 2 shows a cover plate 150 which seals stud 200 with respect to the inside of sole 100.
  • the inside of sole 100 is the side of the sole turned towards the foot of the wearer of the shoe. Also in the case of cover plate it is important to prevent intrusion of moisture and dirt in order to maintain the moveability of stud 200.
  • damping element 300 directly rests on the first surface 130.
  • there is a distance between the damping element 300 and the first surface 130 so that the bottom side 221 of stud body 200 does not rest on the first surface 130. This enables elastic movements of stud 200 vertical to sole 100, up to the magnitude of the distance.
  • Fig. 3 shows a further schematic representation of the embodiment of fig. 2 , wherein the illustrated cross section of stud 200 is orthogonal to the cross section shown in fig. 2 .

  • fig. 3 shows the first surface 130 with opening 131 through which the second attachment device 240 extends.
  • Damping element 300 is arranged on the outside of the first surface 130. Damping element 300 comprises a first groove 310 for receiving a corresponding projection 211 of stud body 210 and second groove 330.
  • Fig. 4 is a perspective view of details of an embodiment of stud 200, wherein the stud is partially cut open.
  • fig. 4 shows sole 100, damping element 300, and stud 200 with stud body 210, first attachment device 220, second attachment device 240, and second surface 230.
  • the figure illustrates an oblong, oval shape of the second surface 230 which widens in the part not visible in fig. 4 .
  • Fig. 5 is another view of the stud of fig. 4 from a different perspective. Again, sole 100, damping element 300, and stud 200 with stud body 210, first attachment device 220, second attachment device 240, and second surface 230 can be seen. Further, fig. 5 shows the first surface 130 as a cross section. Only for clarification the second surface 230 does not rest on the first surface 130, as would be the case in a finally assembled state. As can also clearly be seen, in this embodiment there is a distance between the first surface 130 and bottom side 221 of stud body 210. This enables, as already mentioned above, elastic movements of stud 200 vertical to sole 100, up to the magnitude of this distance.
