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 individual variants of Fig. 6 differ so far only by the formation of the first elements 3a.
- On the left side of Fig. 6 is shown in each case the unloaded and on the right side of the loaded state in the phase of the critical deformation.
- Fig. 6a In the training of Fig. 6a ) is the first, among other things obliquely or tangentially deformable element 3a formed 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 shown in the two detailed representation in the lower part of Fig. 6a ) is sketched.
- 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.
- 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.
- Suitably cut pieces of this position for example, at the bottom of a running shoe or the midsole 4 of the running shoe 2 of Fig. 1 be attached by gluing, as in Fig. 8 under a) is shown schematically.
- 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 tangentially deformable in the same way even in all directions, which may be of additional advantage with respect to the desired rolling behavior.
- the second elements 6b are substantially rigid and functionally correspond to the above-described second elements 3b).
- the elements 6a and 6b may be made smaller than the elements 3a and 3b.
- the height h1 of the entire layer 6 and thus of the first elements 6a may be 8-12 mm, preferably 10 mm
- the height h2 of the second elements 6b may be 4-8 mm, preferably 6 mm.
- the thickness of the layer 6 in the transition regions between the first and second elements may be, for example, 2 mm, but the thickness of the bottom of the first elements 6a is preferably greater than 2 mm.
- the horizontal one Distance between the centers of the first and second elements 6a, 6b may be, for example, 10-20 mm, preferably 15 mm.
- b) shows Fig. 7 the layer 6 is loaded obliquely on a floor 5.
- the first elements 6a are under this load vertically, but above all tangentially or horizontally deformed and no longer protrude beyond the second elements 6b. Further deformation of the first elements 6a is prevented by the second elements 6b.
- the spacings of the first and second elements are preferably chosen to be just as large in order to allow the deformation of the first elements 6a.
- 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.
- 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 Fig. 8 under b) and c) is shown.
- the second elements 6b according to the invention form a continuous surface in which the first elements 6a are scattered, as it is Fig. 8 under d) shows.
- first elements 6a are intermixed with the second elements 6b, are virtually 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 shows 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.
- Fig. 8 The zones introduced above, which are determined either by at least one first element or by at least one second element, can in the embodiments of Fig. 8 be equated with the first elements 6a and the second elements 6b.
- the plurality of first elements 6a arranged next to each other in the transverse direction could also be assigned to only one zone in each case.
- contiguous surface 6b) are considered to be formed by a plurality of zones which alternate longitudinally with first elements 6a or zones formed thereby.
- the first elements 6a correspond to those of Fig. 7
- the second elements 6 b 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 thus can deform tangentially well on all sides.
- the first elements 6a are formed by dimensionally stable nubs, which are connected via a type of elastically deformable membrane with the second elements 6b and thereby horizontally deflected both vertically and to approximately the same extent.
- two elastic layers are connected to each other, wherein at least the outer layer is continuous and except for indentations is relatively flat.
- the recesses form together with approximately opposite bulges of the inner layer first elements 6a.
- the 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 ) educated.

Description
Die vorliegende Erfindung betrifft eine Laufsohle, insbesondere für Sportschuhe gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to an outsole, in particular for sports shoes according to the preamble of
Unter Verformung in tangentialer Richtung soll hierbei eine z.B. durch Scherung bewirkte Verformung in Richtung tangential bzw. parallel zur flächigen Ausdehnung der Laufsohle oder ihrer Lauffläche verstanden werden. Davon zu unterscheiden sind z.B. durch Kompression verursachte Verformungen in Richtung senkrecht zur flächigen. Ausdehnung der Laufsohle oder ihrer Lauffläche. Auf einem horizontalen Untergrund fallen die Richtungen tangential etwa mit horizontal und senkrecht mit vertikal zusammen.In the case of deformation in the tangential direction, a deformation caused by shearing in the direction tangential or parallel to the areal extent of the outsole or its running surface. It is to be distinguished from e.g. deformations caused by compression in a direction perpendicular to the surface. Expansion of the outsole or its tread. On a horizontal surface the directions tangentially coincide with horizontal and vertical with vertically.
Elastisch nachgiebige Laufsohlen sind in grosser Anzahl in verschiedensten Ausbildungen bekannt, wobei elastische Materialien mit den unterschiedlichsten Härten eingesetzt werden. Bekannt sind auch Laufsohlen mit eingelagerten Luft- oder Gel-Polstern. Sie sollen die beim Laufen auftretenden Belastungen abfedern und dadurch den Bewegungsapparat des Läufers, insbesondere dessen Gelenke, schonen und auch ein angenehmes Laufgefühl vermitteln.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.
Die meisten derzeit im Handel erhältlichen Laufschuhe für Sportzwecke weisen Federcharakteristiken auf, die eine Federung primär in vertikaler Richtung bzw. in Richtung senkrecht zur Lauffläche unter Kompression der Sohle erlauben, die in horizontaler bzw. tangentialer Richtung jedoch relativ steif sind und insofern bei schrägem und etwas schiebendem Auftreten nicht genügend nachgeben. Letzteres dürfte seinen Grund u.a. darin haben, dass eine grössere Verformbarkeit der Sohle in horizontaler Richtung eine Art Schwimmeffekt erzeugen würde, der sich negativ auf die Standfestigkeit und Standsicherheit des Läufers auswirken würde. Auch würde der Läufer bei jedem Schritt ein gewisses Stück an Wegstrecke verlieren, da sich die Sohle beim Abstossen vom Auftrittspunkt jeweils erst in der entgegengesetzten Richtung wie beim Auftreten etwas verformen würde. In gewissem Ausmass tritt der Schwimmeffekt bei den handelsüblichen Sportschuhen natürlich bereits auf. Um diesen Effekt zu vermeiden, ist bei den meisten dieser Sportschuhe der vordere Bereich der Sohle, von der üblicherweise die Abstossung erfolgt, relativ hart und unnachgiebig ausgebildet.Most sports running shoes currently commercially available have spring characteristics that allow suspension primarily in the vertical direction, or in the direction perpendicular to the tread, under compression of the sole, which in FIG horizontal or tangential direction, however, are relatively stiff and so far not give enough in an oblique and slightly pushing appearance. The latter is probably due to the fact that a greater deformability of the sole in a horizontal direction would create a kind of floating effect which would have a negative effect on the stability and stability of the runner. Also, the runner would lose a certain amount of distance at each step, since the sole would be deformed when repelled from the point of occurrence only in the opposite direction as the occurrence of something. To some extent, of course, the swimming effect occurs in the commercial sports shoes already on. To avoid this effect, in most of these sports shoes, the front portion of the sole, from which the repulsion is usually made, is relatively hard and unyielding.

Diese Aufgabe wird erfindungsgemäss gelöst durch die Merkmale, wie sie in den Patentansprüchen angegeben sind.This object is achieved according to the invention by the features as indicated in the patent claims.
Die beiden für den gewünschten Effekt erforderlichen Funktionalitäten, nämlich die tangentiale Verformbarkeit einerseits und die Steifigkeit gegenüber tangentialer Verformung jenseits mindestens einer kritischen Verformung andererseits, sind erfindungsgemäss unterschiedlichen Elementen zugewiesen. Indem die ersten Elemente und das mindestens eine zweite Element unabhängig voneinander konzipiert, dimensioniert und hergestellt werden können, ergeben sich für die Praxis weitaus mehr Gestaltungs-, Ausbildungs- und Variationsmöglichkeiten, mit denen sich die gewünschte Anpassung an die Anforderungen der Praxis besser erreichen lässt, als dies mit Elementen wie den bekannten röhrenförmigen Hohlelementen der Fall ist, die beide genannten Funktionen zugleich erfüllen.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.
Eine entsprechende Aufteilung in mehrere tangential verformbare erste Elemente und mehrere steife zweite Elemente sieht grundsätzlich auch schon die vorerwähnte
Die Erfindung sieht deshalb vor, dass sich im Fersen- und im Ballenbereich der Sohle Zonen in Längsrichtung (vom Fersen zum Ballenbereich) mehrfach abwechseln, die einerseits durch die ersten Elemente und andererseits durch das wenigstens eine zweite Element bestimmt sind. Dadurch ist sichergestellt, dass beim Abrollen über den Fersen und/oder über den Ballenbereich stets beide Funktionalitäten in ausreichend enger zeitlicher sowie räumlicher Beziehung zueinander zum Einsatz kommen. Die Charakteristik der erfindungsgemässen Sohle entspricht daher weitgehend derjenigen der
Es können mehrere zweite Elemente vorgesehen sein und es können die durch das mindestens eine zweite Element bestimmten Zonen jeweils durch eines aber auch durch mehrere solcher zweiten Elemente gebildet werden.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.
Wie die aus
Gemäss einer bevorzugten Ausbildung der Erfindung wird die kritische Verformung erst nach einem tangentialen und/oder senkrechten Verformungsweg erreicht, welcher grösser als 20 % der verformbaren Dicke der Sohle, ggf. sogar grösser als 50 % dieser Dicke ist. Bevorzugt soll die tangentiale Verformbarkeit der senkrechten Verformbarkeit sogar etwa entsprechen. Absolut kann das durchaus etwa einen cm ausmachen.According to a preferred embodiment of the invention, 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. Preferably, the tangential deformability of the vertical deformability should even correspond approximately. Absolutely, that can be about a cm.
Bei derart bemessenen Feder- und Dämpfungswegen dämpft die erfindungsgemässe Laufsohle die sich beim Laufen ergebenden Kräfte und Belastungen wirksam ab. Vor allem verhält sich die erfindungsgemässe Sohle optimal dämpfend bei der Landung, indem sie den hierbei vorherrschenden horizontalen Kräften in Laufrichtung z.B. durch Scherung weich nachgeben kann. Beim Abrollen nimmt die erfindungsgemässe Sohle die dabei vorherrschenden vertikalen Kräfte durch vertikale Verformungen ebensogut dämpfend auf. Zusätzlich reagiert sie jedoch auch in dieser Phase durch unterschiedlichste tangentiale Verformungen in unterschiedlichen Richtungen auf Bewegungen zwischen Fuss und Boden, die sich üblicherweise in einem Herumrutschen des Fusses im Schuh äussern und oft zu durchgescheuerten Socken oder gar zu Blasenbildung führen. Der Schuh widersetzt sich nicht der Bewegung, die der Fuss bei der Abrollbewegung gegenüber dem Boden ausführen möchte. Der Schuh ermöglicht ein weitgehend ermüdungsfreies Laufen. Bei voller Belastung in der Phase des Abstossens verliert die erfindungsgemässe Sohle dagegen ihre Dämpfungseigenschaften so gut wie vollständig. In dieser Phase wird die Dämpfung auch nicht mehr benötigt und wäre für ein wirksames Abstossen nur hinderlich. In der Abstossphase verhält sich die erfindungsgemässe Sohle "hart".With such sized spring and damping paths, the outsole according to the invention effectively dampens the forces and stresses that result during running. Above all, 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. During unrolling, the sole according to the invention absorbs the prevailing vertical forces by vertical deformations as well as damping. In addition, however, 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. In the repulsion phase, the sole according to the invention behaves "hard".
An Laufsohlen, die durch verschiedene Läufer länger benutzt wurden, lassen sich grosse Unterschiede hinsichtlich ihrer überwiegenden Belastung an den Abnutzungsmustern feststellen. Dies rührt von unterschiedlichen, für die einzelnen Läufer charakteristischen Laufstilen her. Unterschiede ergeben sich auch aus den verschiedenen Laufdistanzen. So sind Kurzstreckenläufer überwiegend sogenannte Vorderfussläufer mit Belastung praktisch nur des Ballenbereichs. Langstreckenläufer landen demgegenüber meist auf der Ferse und rollen über den ganzen Fuss ab. Hier unterscheidet man sogenannte Aussen- und Innenfussläufer. Aussenfussfussläufer landen auf der Aussenseite der Ferse, rollen über den äusseren Bereich des Mittelfusses ab und stossen sich auch im äusseren Ballenbereich bzw. aus dem Bereich der kleinen Zehen ab. Bei den Innenfussläufern ist das umgekehrt. Es gibt auch Mischformen, bei denen z.B. aussen gelandet, quer über den Mittelfuss abgerollt und aus dem Bereich des grossen Zehs abgestossen wird und umgekehrt. Die erfindungsgemässe Sohle kann sich dadurch, dass bei ihr eine Verformbarkeit vertikal aber auch in tangentialer Richtung nach vorn und hinten möglich ist, all diesen verschiedenen Belastungen gut anpassen und die natürlichen Bewegungen des Fusses mitmachen.On soles that have been used by different runners for longer, large differences in terms of their predominant load on the wear patterns can be observed. This comes from different, for the individual runners characteristic running styles. Differences also arise from the different running distances. Thus, short-distance runners are predominantly so-called forefoot runners with load practically only on the ball area. Long-distance runners usually land on the heel and roll over the entire foot. Here one differentiates so-called outside and inside foot runners. Outrigger runners land on the outside of the heel, roll over the outer area of the Midfoot and repel in the outer ball area or from the area of the small toes. This is the other way around for the inner foot runners. There are also mixed forms in which, for example landed outside, unrolled across the middle foot and repelled from the area of the big toe and vice versa. The sole according to the invention can adapt well to all these different loads and to participate in the natural movements of the foot, since its deformability is vertical but also tangential to the front and back.

Die Hohlelemente 3a sind aus einem Material hergestellt, welches sich unter den beim Laufen auftretenden Belastungen elastisch verformen kann. Die zweiten Elemente 3b sowie die Zwischensohle 4 können ebenfalls eine gewisse Nachgiebigkeit aufweisen, sind im Vergleich mit den Hohlelementen 3a jedoch im wesentlichen steif, insbesondere steif gegenüber tangentialer Verformung. Die Hohlelemente 3a weisen gegenüber den podestförmigen Elementen 3b auch eine grössere Höhe auf und stehen dadurch gegenüber ihnen nach unten vor.The
Die Hohlelemente 3a bilden im Sinne der oben gegebenen Definition jeweils erste Elemente bzw. durch diese bestimmte Zonen". Sofern mehrere Hohlelemente 3a nebeneinander angeordnet sind, können diese auch einer solchen Zone gemeinsam zugerechnet werden. Entsprechend verhält es sich mit den podestförmigen zweiten Elementen 3b, die jeweils "durch das mindestens eine zweite Element bestimmte Zonen" bilden. Längsrichtung der Sohle wechseln sich dadurch die unterschiedlichen Zonen sowohl im Ballen als auch im Fersenbereich mehrfach ab. Sofern die podestförmigen zweiten Elemente 3b einzelne oder mehrere Hohlelemente 3a ringartig zumindest teilweise umschliessen, sind unterschiedliche Zonen auf der Sohlenfläche zusätzlich untereinander vermischt angeordnet.The

Bei der vorbeschriebenen Laufsohle erlauben die Hohlelemente 3a ihre gewünschte elastische Verformbarkeit während die podestförmigen Elemente 3b einerseits den möglichen Grad der Verformung der Hohlelemente 3a bestimmen und begrenzen und andererseits die gewünschte Steifigkeit der Sohle gegen tangentiale Verformung jenseits der kritischen Verformung sicherstellen. Indem diese beiden Funktionalitäten auf unterschiedliche Elemente verteilt sind, besteht bezüglich dieser Elemente ein grösseres Mass an Gestaltungsfreiheit. Beispielsweise können für die ersten und zweiten Elemente unterschiedliche Materialien verwendet werden. Die Hohlelemente 3a müssen auch nicht länger einen festen Reibschluss unter Belastung wie bei der

Bei den vorbeschriebenen Ausführungsformen unterliegen die ersten und/oder die zweiten Elemente 3a, 3b recht hohen Wechselbelastungen unter anderem durch Tangential- bzw. Scherkräfte. Bei rein klebetechnischer Befestigung könnten sich die Elemente auf Dauer von der Zwischensohle 4 lösen. Ein Verbesserung kann hier durch teilweise Einbettung und ggf. zusätzliche formschlüssige Verankerung der Elemente 3a und/oder 3b in die Zwischensohle 4 erreicht werden, so wie dies

Die ersten Elemente 6a haben die Form von Kegelstümpfen, sind hohl und etwas höher als die aus Vollmaterial bestehenden zweiten Elemente 6b, die hier ebenfalls die Form von Kegelstümpfen haben. Die ersten Elemente 6a sind wie die vorbeschriebenen ersten Elemente 3a relativ weich und tangential nach vorn und hinten sowie vertikal deformierbar. Durch ihre rotationssymmetrische Form sind die ersten Elemente 6a sogar nach allen Richtung in gleicher Weise tangential deformierbar, was in bezug auf das gewünschte Abrollverhalten von zusätzlichem Vorteil sein kann.The
Die zweiten Elemente 6b sind demgegenüber im wesentlichen steif und entsprechen funktionell den vorbeschriebenen zweiten Elementen 3b). Die Elemente 6a und 6b können kleiner als die Elemente 3a und 3b ausgeführt sein. Zum Beispiel kann die Höhe h1 der gesamten Lage 6 und damit der ersten Elemente 6a 8 - 12 mm, vorzugsweise 10 mm, betragen und die Höhe h2 der zweiten Elemente 6b 4 - 8 mm, vorzugsweise 6 mm. Die Dicke der Lage 6 in den Übergangsbereichen zwischen den ersten und zweiten Elementen kann z.B. 2 mm betragen, wobei die Dicke des Bodens der ersten Elemente 6a jedoch vorzugsweise grösser als 2 mm ist. Der horizontale Abstand zwischen den Zentren der ersten und zweiten Elemente 6a, 6b kann z.B. 10-20 mm, vorzugsweise 15 mm, betragen.In contrast, the

Die Elastizität der ersten Elemente 6a sollte etwa so gewählt sein, dass die kritische Verformung bei einer Belastung mit etwa 1 kg - 10 kg auftritt. Dieser Wert ist abhängig von der Anzahl der Elemente und ihrer Anordnung auf der Sohlenfläche (lokale Dichte) der gewünschten Dämpfung und vom Läufergewichtes. Der Läufer muss mit seinem (ggf. dynamischen) Gewicht zumindest beim Abstossen die kritische Verformung herbeiführen können. Das gilt für alle möglichen Ausführungsformen erfindungsgemässer Laufsohlen und entsprechend auch für Elemente nach Art der Elemente 3a. Für kleine Schuhgrössen (= eher leichte Läuferin) muss ggf. eine andere Nachgiebigkeit bzw. andere Anzahl von ersten Elementen 3a/6a gewählt werden als für grosse Schuhgrössen (= eher schwerer Läufer). Bei ersten Elementen nach Art der Elemente 3a genügt in der Regel eine Anzahl von 8 - 15 Elementen über den Fersen-und Ballenbereich verteilt. Bei ersten Elementen nach Art der Elemente 6a werden wegen ihrer geringeren Grösse in der Regel mehr als 20 Elemente erforderlich sein.The elasticity of the
