Definitions

  • the present invention relates to an outsole, especially for sport shoes, which is elastically deformable also forwards and backwards in the tangential direction and is essentially stiff with respect to tangential deformation only beyond a critical deformation in the region deformed so far.
  • Deformation in the tangential direction is understood here to be a deformation, brought about, for example, by shearing, in a direction tangential and/or parallel to the two-dimension of extent of the outsole or its tread. Deformations in a direction perpendicular to the two-dimensional extent of the outsole or its tread, caused, for example, by compression, must be differentiated from this. Tangential directions coincide approximately with horizontal directions and perpendicular directions with vertical directions on a horizontal substrate.
  • outsoles Elastically yielding outsoles are known in large numbers in different constructions, elastic materials of different hardness being used. Outsoles with embedded air or gel padding are also known. They are intended to cushion stresses occurring while running and, by these means, take care of the locomotor system of the runner, especially of the joints, and impart a pleasant running sensation.
  • the outsoles of the above-mentioned type avoid the swimming effect, in that, beyond at least a critical deformation in the region deformed so far, they are essentially stiff with respect to tangential deformation.
  • the critical deformation is reached, there is a secure stance on the respective stepping or stressing point, from which he can push off once again without loss of way.
  • tubular hollow elements of a rubber material are described, which, under perpendicular, but especially also under tangential deformation, can be compressed completely forwards and backwards and then, due to friction between their upper and lower half shells, prevent further tangential deformation.
  • the EP 1264556 discloses an outsole for sports shoes, the sole of which has an outer softer layer and an inner harder layer. Projections at the inner, harder layer penetrate the softer outer layer and protrude beyond the latter in the form of supports. A tangential deformability of the sole is not provided and would also be prevented by the supports.
  • a sole known from FR 2709929, has a similar construction, the interior layer being provided with sharp metallic peaks.
  • the UK 2285569 discloses a training show with a sole, which has yielding first and stiff second elements.
  • the first elements are inclined at an angle towards the rear in the direction of the heel and collapsed under load in this direction between the second unyielding elements, which subsequently take up the load.
  • a corresponding deformation of the first elements towards the front is not possible because of their arrangement relative to the second elements.
  • the JP 5309001 discloses a shoe with a sole, which is provided in an inner zone with projections, which are deformable tangentially in all directions and are provided with a cavity.
  • This inner zone is surrounded by an edge zone with stiff low ribs, which, from a particular deformation of the hollow projections onwards, absorb the load.
  • German utility model G 8126601 discloses a shoe with a sole, into which brush-like pieces with rearward directed stiff bristles are inserted. These bristles are intended to make a rapid forward start possible and, by pointing to the rear, a forward sliding. A corresponding deformation of the bristles to the front is not provided and, very likely, also not possible.
  • U.S. Pat. No. 3,299,544 discloses a shoe with a sole, the front heel region of which is provided with transverse ribs, which are directed backward. In comparison to the ribs, the rear edge zone forms a somewhat lower plateau. Under normal running conditions, the ribs are intended to make contact with the ground before the plateau does and, at the same time, to deflect towards the rear until the plateau makes contact with the ground and limits further deformation of the ribs.
  • the DE 29818243 discloses a shoe mechanism with a sole, with elements, which are inclined to the rear and, when the foot is set down, fold over in the direction of the heel and contact the remaining sole.
  • the two functionalities, required for the desired effect, namely the tangential deformability on the one hand and the stiffness with respect to tangential deformation beyond at least a critical deformation on the other, are assigned, pursuant to the invention, to different elements.
  • at least one first element and at least one second element can be conceived, dimensioned and produced independently of one another, far more design, construction and variation possibilities arise in practice, with which the desired adaptation to practical requirements can be achieved better than was the case previously with elements, such as the known tubular hollow elements, which fulfill the two functions named simultaneously.
  • a corresponding division into several tangentially deformable first elements and several stiff second elements is basically also provided for in the aforementioned JP 5309001.
  • the first and second elements are, however, disposed separately from one another there.
  • the first elements are in a first inner zone and the second elements in the boundary zone surrounding the inner zone.
  • the invention therefore sees to it that, in the heel region and/or in the ball region of the sole, zones, which are determined on the one hand by the at least one first element and, on the other, by the at least one second element, alternate repeatedly in the longitudinal direction (from the heel to the ball region).
  • first elements may be provided.
  • the zones, determined by the at least one first element may be formed by one but also by several first such elements.
  • several second elements may be provided and the zones, determined by the at least one second element, may in each case be formed by one but also by several second such elements.
  • the outsoles of the present invention can also be dimensioned so that the at least one critical deformation, limited locally while running, is reached only in the maximally stressed zone and, temporally, only about the stress maximum.
  • the at least one critical deformation, at which the tangential deformability of the inventive outsole is, so to say, frozen in depends on the type of deformation.
  • the deformation need also not be only tangential.
  • a critical deformation may also be reached in the case of a strictly perpendicular or vertical deformation.
  • the critical deformation is reached only after a tangential and/or vertical deformation path, which is greater than 20% of the deformable thickness of the. sole and optionally even greater than 50% of this thickness.
  • the tangential deformability should even correspond approximately to the perpendicular deformability. Absolutely, this may well amount to approximately 1 cm.
  • the inventive outsole effectively dampens the forces and stresses arising while running.
  • the inventive sole behaves optimally damping while landing in that the horizontal forces, predominating here, can yield softly in the running direction, for example, by shearing.
  • the inventive sole absorbs the predominant vertical forces by a vertical deformation equally well due to a damping action.
  • the inventive sole loses its damping properties practically completely. In this phase, damping is also no longer required and would only be a hindrance for effective pushing off. In the pushing off phase, the inventive sole behaves as if it were “hard”.
  • FIG. 1 shows a sport shoe in side view with an outsole of a first embodiment of the invention, a) in the unstressed state, b) when stressed forward at an angle and c) during the pushing off towards the rear,
  • FIG. 2 shows first and second elements of the outsole of FIG. 1 in a diagrammatic detailed representation, a) in the unstressed state, b) when stressed forward at an angle and c) when stressed vertically,
  • FIG. 3 in a similar representation, also shows first and second elements, which are, however, embedded partially and anchored positively in an intermediate sole,
  • FIG. 4 in a similar representation shows an embodiment, for which only first elements are embedded in an intermediate sole, whereas second elements are formed in one piece with this intermediate sole,
  • FIG. 5 shows a variation of the embodiment of FIG. 4 , a) in the not stressed state and, under b), in the stressed state, the first elements, however, being embedded so deeply in the intermediate sole 4 , that second elements, as extra parts, no longer are required,
  • FIG. 6 diagrammatically under a) and b), shows further variations of the type of FIG. 5 .
  • FIG. 7 in a diagrammatic detailed representation, shows a continuous layer or stratum, on which first and second elements are formed, a) unstressed, b) stressed forward at an angle and c) stressed vertically,
  • FIG. 8 shows several views a) to d) of the running surface of inventive outsoles
  • FIG. 9 under a) to e) shows further layers of FIG. 7 in the unstressed state.
  • FIG. 1 is not necessarily the preferred embodiment, but by means of which, however, the inventive teachings can be represented well.
  • FIG. 1 shows a running shoe 2 , which is equipped with an inventive outsole 1 .
  • the outsole 1 is formed by a plurality of first profile-like hollow elements 3 a, similar to those already known from WO 03/102430, as well as by several platform-like second elements 3 b.
  • the hollow elements 3 a may have a height of, for example, 15 mm and the platform-like elements 3 b a height of, for example, 10 mm.
  • the hollow elements 3 a, as well as the second elements 3 b may extend over the whole width of the running shoe 2 . They may also, however, be disposed in several rows next to one another.
  • the platform-like elements 3 may also enclose individual or several hollow elements 3 a at least partly in annular fashion.
  • the elements 3 a, 3 b are attached to the underside of an intermediate sole 4 of the running shoe 1 , for example, by adhesion.
  • the hollow elements 3 a are prepared from a material, which can be deformed elastically under the stresses occurring during running.
  • the second elements 3 b, as well as the intermediate sole 4 may also have a certain resilience; however, in comparison with the hollow elements 3 a, they are essentially stiff, especially stiff with respect to tangential deformation. Compared to the platform-like elements 3 b, the hollow elements 3 a are also higher, protruding downward from them.
  • the hollow elements 3 a in each case form “certain zones through the at least one first element”. If several hollow elements 3 a are disposed next to one another, they can also be classed jointly with such a zone. The situation is similar for the platform-like second elements 3 b, which in each case form “certain zones through the at least one second element”. As a result, in the longitudinal direction of the sole, the different zones alternate repeatedly in the ball region as well as in the heel region. If the platform-like second elements 3 b enclose individual or several hollow elements 3 a at least partly in annular fashion, different zones, which additionally are mixed among one another, are disposed on the sole surface.
  • the running shoe 2 is produced as shown, for example, in FIG. 1 b and, when a step is taken, stressed at an angle to the front as shown by the stress arrow P 1 , initially only the protruding hollow elements 3 a come into contact with the ground 5 and are deformed vertically and also horizontally with elastic cushioning of the stresses. This deformation is limited by the adjacent, platform-like second elements 3 b, as soon as the hollow elements 3 a are aligned with these at the same height. From this time onwards, the platform-like second elements take over the main portion of the stress and, because of their already mentioned higher stiffness, no longer permit at least any significant tangential displacement of the running shoe with respect to the ground 5 .
  • FIG. 2 shows one of the hollow elements 3 a as well as to platform-shaped elements 3 b of FIG. 1 and, moreover, under a) in the unstressed state and, under b), under a tangential stress.
  • the hollow elements 3 a permit the desired elastic deformability, while the platform-like elements 3 b, on the one hand, determine and limit the possible degree of deformation of the hollow elements 3 a and, on the other, ensure the desired stiffness of the sole against tangential deformation beyond the critical deformation. Since these two functionalities are distributed among different elements, there is a greater degree of configurational freedom with respect to these elements. For example, different materials can be used for the first and second elements.
  • the hollow elements 3 a also need no longer make a fixed frictional connection under load possible as in the case of the WO 03/102430 and, on the whole, are stressed significantly less.
  • the second elements 3 b need not carry all the dynamic weight and the stress on them is relieved by the second elements 3 b at a still noncritical degree of deformation. It is of advantage if the surfaces of the second elements 3 b, coming into contact with the ground, have a good grip on the ground, which may be attained optionally by a special nature of these surfaces.
  • the hollow elements 3 a may be characterized as “damping elements” and the platform-like elements 3 b as supporting elements.
  • the embodiments, explained above, are distinguished by extremely large deformation paths, which, between the unstressed state, for example of FIG. 1 a ) and the state, for example, of FIG. 1 b ) may amount to more than 20% and even to more than 50% of the vertical overhang of the hollow element 3 a over the platform-shaped elements 3 b.
  • the runner therefore hovers “as if on clouds” and, at no time, has a sensation of unsteadiness.
  • the first and/or the second elements 3 a, 3 b are subjected to quite high alternating loads, for example, due to tangential or shearing forces. If attached strictly by gluing, the elements could, in the long run, detach from the intermediate sole 4 .
  • An improvement can be achieved here, for example, by partly embedding and, optionally, additionally positively anchoring the elements 3 a and/or 3 b in the intermediate sole 4 , as shown in FIG. 3 for one of the hollow elements 3 a and two of the platform-shaped elements 3 b.
  • FIG. 4 shows an embodiment, for which only the hollow element 3 a shown is embedded in the intermediate sole 4 .
  • the two elements 3 b are constructed in one piece with the intermediate sole 4 and integrally molded to the latter directly.
  • the hollow element 3 a is anchored in the intermediate sole even better by a dovetail connection.
  • FIG. 5 A variation of the embodiment of FIG. 4 is shown in FIG. 5 and, moreover, in the unstressed state under a) and in the stressed state under b).
  • the hollow elements 3 a are embedded here so deeply in the intermediate sole 4 , that platform-like protruding second elements, like the elements 3 b that were described previously, are no longer required at all and are therefore also not formed.
  • the “normal” surface 4 . 1 of the intermediate sole 4 assumes the function of the previously described second elements 3 b. So that the hollow elements 3 a can be deformed “recessed”, that is, at an angle in the depression 4 . 2 , in which they are disposed, until they are aligned with the surface 4 . 1 of the intermediate sole, the depressions 4 . 2 must be constructed sufficiently broad and wide, as is also shown in FIG. 5 .
  • FIG. 6 shows further variations of the type of FIG. 5 , for which the first elements 3 a also are embedded relatively deeply in the intermediate sole 4 and for which the “normal” surface 4 . 1 of the intermediate sole 4 assumes the function of the above-described second elements 3 b.
  • the individual variations of FIG. 6 differ only in the construction of the first elements 3 a. On the left side of FIG. 6 , in each case the unstressed state is shown and, on the right side, the stressed state in the phase of critical deformation.
  • the first element 3 a which can be deformed, for instance, at an angle or tangentially, is constructed in the form of a pin.
  • the indentation 4 . 2 may, for example, be constructed round here. All around, the edge of the indentation is the same distance from the pin 3 a, which is disposed in the center of the indentation, as sketched in the two detailed representations in the lower part of FIG. 6 a ).
  • the deformable element 3 a is constructed in the form of a small tube, which is disposed with its axis perpendicular to the intermediate sole 4 . Otherwise, the construction and representation correspond to those of FIG. 6 a ).
  • FIG. 7 shows a layer or stratum 6 of an elastically deformable material, at which first elements 6 a and second elements 6 b are alternately formed in the unstressed state.
  • This layer 6 can be produced in one piece and as a large piece.
  • the same sequence of first elements 6 a and second elements 6 b may be provided in the direction perpendicular to the plane of the drawing, so that a structure results, for which each first element is surrounded by four second elements and vice versa.
  • the first and second elements are then also mixed with one another again, as was already discussed.
  • Pieces of this layer, suitably cut to size, may be fastened by adhesion, for example, to the underside of a running shoe or of the intermediate sole 4 of the running shoe 2 of FIG. 1 , as shown diagrammatically in FIG. 8 under a).
  • the first elements 6 a have the shape of truncated cones, are hollow and somewhat higher than the elements 6 b, which consists of a solid material and also have the shape of a truncated cone here. Like the previously described first elements 3 a, the first elements 6 a are relatively soft and can be deformed tangentially forward and rearward as well as vertically. Due to their rotationally symmetrical form, the first elements 6 a can even be deformed tangentially in the same manner in all directions, which may be additionally advantageous in relation to the desired uncoiling behavior.
  • the second elements 6 b are essentially stiff and correspond functionally to the previously described second elements 3 b ).
  • the elements 6 a and 6 b may be smaller than the elements 3 a and 3 b.
  • the height h 1 of the total layer 6 and, with that, of the first element 6 a may be 8 to 12 mm and preferably 10 mm and the height h 2 of the second elements 6 b maybe 4 to 8 mm and preferably 6 mm.
  • the thickness of the layer 6 in the transition region between the first and second elements may, for example, be 2 mm, the thickness of the bottom of the first elements 6 a, however, preferably being greater than 2 mm.
  • the horizontal distance between the centers of the first and second elements 6 a, 6 b may, for example, be 10 to 20 mm and preferably 15 mm.
  • FIG. 7 shows the layers 6 loaded at an angle on a ground 5 .
  • the first elements 6 a are deformed vertically under this load, especially, however, tangentially or horizontally and no longer protrude over the second elements 6 b. Further deformation of the first elements 6 a is prevented by the second elements 6 b.
  • the distances of the first and second elements preferably are selected to have such a magnitude, that the first elements 6 a can achieve the deformation shown.
  • the extent of the tangential deformation path before it reaches the critical deformation is larger here than the possible vertical deformation path and, for the dimensions given above, amounts to at least 5 mm absolute.
  • FIG. 7 shows the layer 6 under a vertical load.
  • the elasticity of the first elements 6 a should be selected so that the critical deformation occurs at a load of approximately 1 kg to 10 kg. This value depends on the number of elements and their arrangement on the surface of the sole (local density), the desired damping and the weight of the runner. With his (optionally dynamic) weight, the runner, at least while pushing off, must be able to bring about the critical deformation. This is true for all possible embodiments of inventive outsoles and correspondingly also for elements of the type of elements 3 a. A different compliance or a different number of first elements 3 a / 6 a must be selected for small shoes sizes (a runner of lesser weight) land for larger shoes sizes (a runner of greater weight). For first elements of the element 3 a type, a number of 8 to 15 elements, distributed over the heel and ball region, is usually sufficient. Because of their smaller size, usually more than 20 first elements of the 6 a type are required.
  • the second elements 6 b may be constructed perpendicular to the plane of the drawing as elongated ribs, regularly or irregularly shaped platforms or the like, as shown in FIG. 8 under b) and c).
  • the second elements 6 b may even form a coherent surface, in which the first elements 6 a are disposed in scattered fashion, as shown in FIG. 8 under d).
  • first elements 6 a are disposed mixed with the second elements 6 b, embedded regularly between the second elements 6 b and, by these means, protected against excessive loading with high abrasion.
  • first and second elements are stressed by these means also in each case in close spatial as well as temporal sequence, so that the behavior of the sole and the running sensation are determined always by both elements.
  • the mixed distribution of the first and second elements extends also over the whole of the ball and heel regions.
  • first and second elements usually are not required. It is therefore usually sufficient for most applications if layers 6 are disposed separately in each case only in the ball and heel regions. Instead or in addition to a division transverse with respect to the longitudinal direction of the shoe, a longitudinal division could also be made. A longitudinal and transverse division with four layers 6 is shown in FIG. 8 under c). By these means, adaptation to different shoes sizes could also be attained with standard elements, in that these are simply disposed suitably, especially closer together or further apart from one another. Finally, different layers with different properties could be provided in the different regions.
  • the several first elements 6 a which are disposed next to one another in the transverse direction, can also be counted as only one zone.
  • the coherent surface 6 b ) in the example of FIG. 8 d may be considered as being formed of several zones, which alternate in the longitudinal direction with first elements 6 a or with zones formed by these elements.
  • the first elements 6 a correspond to those of FIG. 7 .
  • the second elements 6 b are provided with a rectangular cross-section.
  • the first elements 6 a are made from a solid material; however, they have a thickened head on a narrower neck and may thus be deformed well sideways in all directions as well as tangentially.
  • the first elements 6 a are formed by dimensionally stable burls 6 aa, which are connected over a type of a elastically deformable membrane 6 ab with the second elements 6 b and by these means, can be deflected vertically as well as, to about the same extent, horizontally.
  • two elastic strata are connected with one another, at least the outer layer being continuous and relatively flat with the exception of indentations.
  • the indentations together with approximately opposite, similar protrusions of the inner layer, form first elements 6 a.
  • the indentations moreover, in the form of a buffer, enable different first elements 6 a simultaneously to be deformed tangentially in different directions.
  • the second elements 6 b are formed by the outer layer between the indentations and the platforms or ribs below, as shown, by way of example, in FIG. 9 a ).
