Definitions

  • the present invention relates to an outsole, in particular for sports shoes according to the preamble of patent claim 1.
  • Elastic compliant outsoles are known in large numbers in a variety of forms, elastic materials are used with a variety of hardnesses. Also known are outsoles with embedded air or gel pads. They are intended to cushion the loads occurring during running and thereby protect the musculoskeletal system of the runner, in particular its joints, and also convey a pleasant ride.
  • Out EP 1264556 is an outsole for sports shoes, in which the sole has an outer, softer layer and an inner, harder layer. Projections on the inner, harder position penetrate the softer, outer layer. A tangential deformability of the sole is not provided.
  • a training shoe with a sole that has compliant first and stiff second members.
  • the first elements are inclined at an angle to the rear towards the heel part and collapse under load in this direction between the second unyielding elements, which then take over the load.
  • a corresponding deformation of the first elements forward is not possible because of their arrangement relative to the second elements.
  • a shoe is known with a sole which is provided in an inner zone with projections which are tangentially deformable in all directions and provided with a cavity.
  • This inner zone is surrounded by a border zone with stiff, lower ribs, which take over the load from a certain deformation of the hollow protrusions.
  • Out DE 29818243 is a shoe drive with a sole known with rearwardly inclined elements that fold in the direction of the heel and create the rest of the sole.
  • US 6082024 is a shoe sole with pressure-stimulating elements known which protrude downwards with respect to the remaining Sohlenfphie and are pressed under load when running vertically upwards under compression of a soft midsole. At a tangential deformation the elements are prevented by engagement in the midsole.
  • Object of the present invention is to specify how outsoles of the WO 03/103430 known type better adapted to the different requirements of the practice including the requirements of different sports in an economical manner.
  • the two functionalities required for the desired effect namely the tangential deformability on the one hand and the rigidity with respect to tangential deformation beyond at least one critical deformation on the other hand, are assigned to different elements according to the invention.
  • the fact that the first elements and the at least one second element can be designed, dimensioned and manufactured independently of each other results in much more design, training and variation possibilities for the practice, with which the desired adaptation to the requirements of the practice can be better achieved. as is the case with elements such as the known tubular hollow elements, which fulfill both functions at the same time.
  • a corresponding division into a plurality of tangentially deformable first elements and a plurality of rigid second elements basically also already provides the aforementioned JP 5309001 in front.
  • the first and second elements are arranged separately from one another: the first elements in an inner zone and the second elements in a peripheral zone surrounding the inner zone.
  • so-called inner or outer foot runner which will be discussed below, roll exclusively on the hard, arranged in the edge zone elements or that when it is rolled over the middle of the sole, practically only the first elements are charged and this comes to a floating effect, the just want to avoid the invention.
  • the invention therefore provides that in the heel and in the ball area of the sole zones in the longitudinal direction (from the heel to the ball area) alternate several times, which are determined on the one hand by the first elements and on the other hand by the at least one second element. This ensures that when rolling over the heels and / or over the ball area both functions are always used in sufficiently close temporal and spatial relationship to each other.
  • the characteristic of the inventive sole therefore largely corresponds to that of WO 03/103430 ,
  • Several second elements can be provided and the zones determined by the at least one second element can each be formed by one but also by a plurality of such second elements.
  • out WO 03/103430 known outsole can also be the outsole according to the present invention are dimensioned so that the at least one critical deformation while running locally limited only in the respective maximum loaded zone and time is only around the maximum load around.
  • the at least one critical deformation in which the tangential deformability of the outsole according to the invention is frozen, so to speak, depends on the type of deformation. A critical deformation can be achieved even with purely vertical or vertical deformation.
  • the critical deformation is achieved only after a tangential and / or vertical deformation path, which greater than 20% of the deformable thickness of the sole, possibly even greater than 50% of this thickness.
  • the tangential deformability of the vertical deformability should even correspond approximately. absolutely, that can be about a cm.
  • the outsole according to the invention effectively dampens the forces and stresses that result during running.
  • the sole according to the invention behaves in an optimally damping way on landing, in that it compensates for the horizontal forces in the direction of travel, which are predominant here. can yield softly by shearing.
  • the sole according to the invention absorbs the prevailing vertical forces by vertical deformations as well as damping.
  • it also reacts in this phase by a variety of tangential deformations in different directions to movements between foot and floor, which usually manifest in a slipping of the foot in the shoe and often lead to frayed socks or even blistering.
  • the shoe does not resist the movement that the foot would like to make when rolling against the ground.
  • the shoe allows a largely fatigue-free running.
  • At full load in the phase of the repulsion loses the sole according to the invention, however, their damping properties as well as completely. In this phase, the damping is no longer needed and would only be a hindrance to an effective repulsion.
  • the sole according to the invention behaves "hard".
  • Fig. 1 shows an equipped with an outsole 1 running shoe 2.
  • the outsole 1 is formed by a plurality of first profile-like hollow elements 3a, as they are already out WO 03/103430 are known and several platform-shaped second elements 3b.
  • the hollow elements 3a may have a height of eg 15 mm and the platform-shaped elements 3b have a height of eg 10 mm.
  • Both the hollow elements 3a and the second elements 3b can extend over the entire respective width of the running shoe 2. However, they could also be arranged in several rows next to each other.
  • the platform-shaped elements 3b could surround at least partially single or multiple hollow elements 3a ring-like. Attached are the elements 3a, 3b on the underside of a midsole 4 of the running shoe 1, for example by gluing.
  • the hollow elements 3a are made of a material which can deform elastically under the loads occurring during running.
  • the second elements 3b and the midsole 4 may also have a certain flexibility, but in comparison with the hollow elements 3a substantially rigid, in particular stiff against tangential deformation.
  • the hollow elements 3a have compared to the platform-shaped elements 3b and a greater height and are therefore in front of them downwards.
  • the hollow elements 3a form in the sense of the definition given above in each case first elements or zones determined by them. "If several hollow elements 3a are arranged next to one another, these can also be assigned to one such zone together.
  • the platform-shaped second elements 3b In the longitudinal direction of the sole, the different zones in the bale as well as in the heel area alternate several times, provided that the platform-shaped second elements 3b at least partially surround individual or several hollow elements 3a different zones on the sole surface additionally mixed with each other.
  • Fig. 2 shows in a detailed view of one of the hollow elements 3a and two platform-shaped elements 3b of Fig. 1 namely under a) in the unloaded condition and under b) tangentially loaded among other things.
  • Under c) is a deformation vertical or shown vertically down, from which it is clear that the above-mentioned advantages in terms of stability and repulsion are achieved without loss of travel even under purely vertical load.
  • the hollow elements 3a allow their desired elastic deformability while the platform-shaped elements 3b on the one hand determine and limit the possible degree of deformation of the hollow elements 3a and on the other hand ensure the desired stiffness of the sole against tangential deformation beyond the critical deformation.
  • different materials may be used for the first and second elements.
  • the hollow elements 3a no longer need a firm frictional engagement under load as in the WO 03/103430 enable and are burdened much less. Above all, they do not have to carry the full dynamic weight and are relieved by the second elements 3b at a still uncritical degree of deformation. It is advantageous if the surfaces of the second elements 3b which come into contact with the ground have a good "grip" with respect to the ground, which may possibly be achieved by a special nature of these areas.
  • the hollow elements 3a can be characterized as "damping elements" and the platform-shaped elements 3b as supporting elements.
  • the embodiments described above are characterized by extremely large deformation paths, which between the unloaded state, for example according to Fig. 1 a) and the condition eg according to Fig. 1b ) may well be more than 20%, possibly even more than 50% of the vertical supernatant of the hollow elements 3a on the platform-shaped elements 3 b.
  • the runner thus floats "as if on clouds", but never has an insecure sense of stability.
  • the first and / or the second elements 3a, 3b are subjected to relatively high alternating loads, inter alia, by tangential or shear forces.
  • the elements could permanently detach from the midsole 4.
  • Partial embedding and possibly additional positive anchoring of the elements 3a and / or 3b are achieved in the midsole 4, as this Fig. 3 for one of the hollow elements 3a and two of the platform-shaped elements 3b.
  • Fig. 4 shows an embodiment in which only the illustrated hollow element 3a embedded in the midsole 4, the two elements 3b, however, formed integrally with the midsole 4 and formed directly on this.
  • the anchoring of the hollow element 3a in the midsole 4 is further improved by a dovetail connection.
  • FIG. 5 A variant of the embodiment of Fig. 4 is in Fig. 5 shown under a) in the unloaded and under b) in the loaded state.
  • the hollow elements 3a are so deeply embedded in the midsole 4 that platform-like protruding second elements such as the above-described elements 3b are no longer needed and therefore are not formed.
  • the "normal" surface 4.1 of the midsole 4 assumes the function of the above-described second elements 3b in this embodiment.
  • the hollow elements 3a in the wells 4.2 in which they are arranged, "sunk", ie obliquely each can be deformed into it until they are flush with the surface 4.1 of the midsole, the wells 4.2 must be sufficiently wide or wide, as in Fig. 5 also shown.
  • Fig. 6 shows under a) and b) other variants in the manner of Fig. 5 in which the first elements 3a are likewise embedded relatively deep in the midsole 4 and in which the "normal" surface 4.1 of the midsole 4 assumes the function of the above-described second elements 3b.

  • the deformable element 3a is designed in the manner of a tube arranged with its axis perpendicular to the midsole 4. Otherwise, the training and presentation corresponds to those of Fig. 6a ).
  • Fig. 7 shows under a) a layer or layer 6 of an elastically deformable material having alternately formed first 6a and second elements 6b in the unloaded state.
  • This layer 6 can be made in one piece and over a large area.
