Definitions

• the present invention relates to an outsole, in particular for sports shoes, with elastic deformability also in the tangential direction to the front and to the rear, which is only beyond beyond at least one critical deformation in the deformed area substantially rigid against tangential deformation.
• 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.
• 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 and protrude beyond it in the manner of studs. A tangential deformability of the sole is not provided and would also be prevented by the studs.
• a sole known from FR 2709929 wherein the inner layer is provided with sharp, metallic tips.
• JP 5309001 a shoe with a sole is known, which is provided in an inner zone with tangentially deformable in all directions, provided with a cavity projections.
• 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.
• the front heel area is provided with transversal, inclined back ribs.
• the rear edge zone of the heel area forms a plateau slightly lower than the ribs.
• the ribs should come into contact with the ground during normal running in front of the plateau and thereby be pushed backwards until the plateau gets in contact with the ground and limits further deformation of the ribs.
• Sport shoes tailored to the requirements of the respective sport are offered, whereby, above all, the training of the soles plays an important, if not the decisive, role for their respective suitability.
• Object of the present invention is to specify how outsoles of the known from WO 03/102430 type can be 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. Since the at least one first and the at least one second element can be designed, dimensioned and manufactured independently of one another, there are many more possibilities for design, training and variation 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 already provides the aforementioned JP 5309001.
• 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 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 / or 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 at least one first element 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 sole according to the invention therefore largely corresponds to that of WO 03/102430.
• first elements can be provided.
• the zones determined by the at least one first element can each be formed by one but also by a plurality of such first elements.
• a plurality of 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.
• the outsole according to the present invention can also be dimensioned such that the at least one critical deformation during running is locally limited only in the respectively maximally loaded zone and in time only around the load maximum.
• 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. The deformation does not just have to be tangential. 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.
• this results in a high load peak, even if they are provided with a pronounced vertical damping, because of the so far lacking tangential deformability.
• the sole according to the invention absorbs the prevailing vertical forces by vertical deformations as well as damping.

• FIG. 1 shows a running shoe 2 equipped with an outsole 1 according to the invention.
• the outsole 1 is formed by a plurality of first profile-like hollow elements 3a, as already known from WO 03/102430, as well as a plurality of platform-shaped second elements 3b.
• the hollow elements 3a may have a height of e.g. 15 mm and the platform-shaped elements 3b have a height of e.g. 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 at the bottom of a midsole 4 of the running shoe 1, e.g. by sticking.
• 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 also a greater height and are therefore in front of them down.
• the hollow elements 3a each form "zones determined by the at least one first element". If a plurality of hollow elements 3a are arranged side by side, they can also be attributed to such a zone together.
• the platform-shaped second elements 3b which each form "zones determined by the at least one second element”.
• the various zones alternate in the bale as well as in the heel area several times. If the platform-shaped second elements 3b individually or several hollow elements 3a at least partially surround, different zones on the sole surface are additionally mixed with each other.

• 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 to allow a firm frictional engagement under load as in WO 03/102430 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 above-described embodiments are characterized by extremely large deformation paths, which between the unloaded state, e.g. according to FIG. 1 a) and the state e.g. According to Fig. 1b) may well more than 20%, possibly even more than 50% of the vertical supernatant of the hollow elements 3a on the platform-shaped elements 3 b may be.
• 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 shown in 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 shown in Fig. 5 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 individual variants of FIG. 6 differ insofar only by the formation of the first elements 3 a.
• the first, inter alia, obliquely or tangentially deformable element 3 a is designed in the manner of a pin.
• the recess 4.2 in the midsole 4 may be formed here round, for example, and with its edge on all sides the same distance from the arranged in its center pin 3a, as sketched in the two detailed representation in the lower part of Fig. 6a).
• 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 that 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. In the direction perpendicular to the plane of the drawing, the same sequence of first 6a and second elements 6b may be provided, so that a structure results in which in each case a first element is surrounded by four second elements and vice versa. The first and second elements are then mixed together again, as already mentioned.
• Suitable cut pieces of this layer may e.g. attached to the underside of a running shoe or the midsole 4 of the running shoe 2 of Fig. 1 by gluing, as shown schematically in Fig. 8 a).
• the first elements 6a have the shape of truncated cones, are hollow and slightly higher than the solid material second elements 6b, which also have the shape of truncated cones here. Like the above-described first elements 3a, the first elements 6a are relatively soft and tangentially forward and backward and vertically deformable. Due to their rotationally symmetrical shape, the first elements 6a are even tangentially deformable in all directions in the same way, which may be of additional advantage with respect to the desired rolling behavior.
• the second elements 6b are substantially rigid and correspond functionally to the protruding second elements 3b).

• the spacings of the first and second elements are preferably chosen to be just as large in order to allow the first elements 6a the deformation shown.
• the extent of the tangential deformation path until the critical deformation is reached is greater here than the possible vertical deformation path and amounts to absolutely 5 mm for the dimensions given above.
• Fig. 7 shows the layer 6 under vertical load.
• the second elements 6b may be formed perpendicular to the plane of the drawing as elongated ribs, regularly or irregularly shaped pedestals or the like, as shown in Fig. 8 b) and c).
• the second elements 6b could even form a continuous surface in which the first elements 6a are scattered, as shown in Fig. 8 at d).
• first elements 6a are intermixed with the second elements 6b, are actually embedded between the second elements 6b and thereby protected against excessive wear with high abrasion.
• first and second elements are thereby burdened in each case in close spatial and temporal sequence, so that the behavior of the sole and the running feeling is always determined by both elements.
• the mixed distribution of the first and second elements also extends over the entire bale and heel area.
• first and second elements are usually not needed. It is therefore sufficient for most applications, when layers 6 are arranged separately only in the bale and heel area. It could be made instead of or in addition to a transverse pitch with respect to the longitudinal direction of the shoe also a longitudinal division. A longitudinal and transverse division with four layers 6 is shown in FIG. 8 under c). As a result, an adaptation to different shoe sizes could be achieved with standard elements by these are easily suitable, in particular more or less far away from each other. Finally, different layers with different properties could be provided in the different areas.
• Embodiments of Fig. 8 with the first elements 6a and the second elements 6b are equated.

• the first elements 6a correspond to those of FIG. 7.
• the second elements 6b are provided with a rectangular cross section.
• the first elements 6a are made of solid material, but have a thickened head on a slimmer neck and can thus also deform tangentially well on all sides.
• the first elements 6a are formed by dimensionally stable nubs 6aa, which are connected via a kind of elastically deformable membrane 6ab with the second elements 6b and thereby horizontally deflectable both vertically and to approximately the same extent.
• Indentations also allow for a kind of buffer that different first elements 6a can be tangentially deformed simultaneously in different directions.
• the second elements 6b are formed by the outer layer between the indentations and underlying pedestals or ribs in the manner of Fig. 9a).
