Definitions

  • the invention relates to a shoe bottom, in particular for sports shoes, with the features according to the preamble of patent claim 1.
  • a long deformation path requires a relatively thick outsole, however, through which the runner loses the desired track contact feeling and, above all, undergoes not only compressive deformations directed vertically to the track, but also to the side, i.e. deformations parallel to the track, and thereby a feeling of swimming generated.
  • a compromise is therefore always made which amounts to a reduction in the damping capacity.
  • the object of the present invention is therefore to provide a shoe bottom of the type specified which provides adequate cushioning and with which the deformation behavior in the individual sole sections can be adapted in a simple manner to the biomechanics of the foot during the rolling process.
  • the weight of the shoe bottom should be reduced.
  • the invention thus frees itself from the use of flat sole parts for a shoe bottom, which perform the intended functions due to their compressive deformability, and essentially replaces them with individual supporting elements, each of which represents a circumferentially closed box profile with internal struts.
  • the compressive deformability of such a box profile is not based on the compressibility of the material, but on the bending elasticity of the straps, walls and struts of the box profile, whereby the deformation behavior can be very largely influenced and changed by their design and arrangement relative to one another and by their individual dimensions.
  • By making relatively minor changes to the arrangement of the inner struts a variety of differently deformable support elements can therefore be created, which allows the flexibility to be controlled in a targeted manner across the surface of the sole base.
  • support elements of this type in contrast to solid compressible sole layers, allows a specific anisotropy to be generated, which has the effect that the shoe bottom in the direction of the weight load, i.e. essentially perpendicular to the outsole surface, is noticeably more flexible than transverse to this direction.
  • anisotropy By utilizing such anisotropy, it is possible to obtain relatively long damping paths without being accompanied by a correspondingly extensive lateral deformability.
  • each support element has at least one with its ends on the lower belt and close to one of the support walls each supporting arch.
  • the support arch forms a simple upward curvature, ie it is designed like a bridge, and its apex lies approximately in the middle of the upper chord. But it is also conceivable to make the support arch wave-shaped so that it forms in the middle a downward curvature lying between the two upward curvatures, the apex of which is approximately in the middle of the lower flange.
  • a pressure load acting from above is distributed over the upper flange to the two side walls and to the curvature or curvatures of the support arch, the division taking place in relation to the flexibility of the side walls and the support arch.
  • a substantial part of the pressure load is introduced into the lower flange via the support arch while deforming it.
  • a very extensive influence on the deformation behavior can only be achieved by the fact that and to what extent the support arch is firmly connected with its or its curvatures to the upper chord and possibly with its counter-curvature to the lower chord.
  • a firm connection results in a greater stiffening, through which the support arch absorbs a larger proportion of the forces to be transmitted.
  • the support arch is only attached to the lower flange with its lower ends and can move with its curvature or curvatures relative to the upper flange, it can deflect to the side.
  • the struts can also be formed by in turn closed ring or box profiles, which are arranged in the interior of the support element.
  • at least one - then centrally arranged - annular profile is provided, which extends from the upper chord to the lower chord and is firmly connected to at least one of the belts.
  • the support elements consist of a relatively hard, flexible plastic, e.g. made of hard-set polyamide, polyurethane or polyester. These plastics can also be reinforced with carbon or glass fibers.
  • the support elements are furthermore arranged one behind the other and - preferably - parallel to one another in the longitudinal direction of the shoe, at least their width changing according to the sole contour.
  • the lateral support walls form the lateral sole edge surface, which is interrupted however due to the spacing of the supporting elements.
  • the support elements can either be manufactured in the individual sizes, which together form a shoe bottom, by injection molding. However, it is also possible to produce them in the extrusion or extrusion process and cut them to the desired length.
  • An essential part of the support structure formed by the shoe bottom according to the invention is formed by the foot-side cover layer or cover plate, which also consists of a relatively hard, but flexible plastic and is connected to the upper straps of the individual support elements, for example glued.
  • the outsole is connected, for example glued, to the lower straps, which also represents an important part of the supporting structure and should also be flexible. It can be profiled on its running side, for example in the form of a glued-on wear sole.
  • the outsole connected to the lower straps is not a mandatory requirement. Rather, the outsole could also be dispensed with, so that the lower straps themselves form the running side of the shoe bottom with their underside and are optionally provided or equipped for this purpose with a profiling.
  • a sole support according to DE-PS 37 16 424 is advantageously suitable as a cover layer or cover plate.
  • the sports shoe shown in FIGS. 1 and 2 each consists of a shaft 1 and a shoe bottom designated as a whole by 2 or 2 '.
  • the upper 1, to which the present invention does not relate, may be of any type and design and may or may not have an insole (not shown). It is connected to the shoe bottom 2 or 2 ', for example by gluing.
  • the shoe bottom 2 shows the individual components of the shoe bottom 2, namely a cover plate 20 made of flexible plastic, a number (in the exemplary embodiment ten) of support elements 21, which are also made of a relatively hard but flexible plastic, and an outsole layer 22, which has a profiling on its barrel side.
  • the outsole 22 is made of an elastically resilient material, e.g. Rubber, which has a lower hardness and thus a greater compressibility than the material of the support elements 21 and the cover plate 20th
  • Both the cover plate 20 and the outsole layer 22 have the sole shape known from conventional shoes.
  • the width of the support elements 21, which is measured transversely to the longitudinal direction of the sole, is selected so that they each extend to the outer edge of the cover plate 20 or the outsole layer 22 and reproduce their contour.
  • the support elements 21 can have a thickness measured in the longitudinal direction of the sole of 0.5 to 1.5 cm, which results in the distances provided between them for a certain sole size.
  • FIGS. 5a and 5b shows both the different width and the different height of the support elements 21 in the individual sole sections.
  • the height of the support element 21 according to FIG. 5a is higher than that of the support element according to FIG. 5b.
  • the support elements 21 adjacent to these support elements each have a stepwise increasing or decreasing height, so that the wedge shape of the shoe bottom which tapers towards the tip of the shoe and becomes clear from FIG. 1 results.
  • the support elements 21 each represent a circumferentially closed box profile that is open towards the end faces.
  • the embodiment shown in FIGS. 5a, b corresponds to that according to FIG. 11.
  • the support element 21 used in this exemplary embodiment has an upper flange 201, a lower flange 202, lateral support walls 203 and a support arch 204 arranged as a strut in the interior of the profile cross section.
  • the support arch 204 has a simple, upward curvature in the manner of a bridge and has grown with its lower ends 205 at a small distance (in the exemplary embodiment about 1/10 of the total width of the support element 21) from the side support walls 203 on the lower flange 202 " ".
  • the support arch 204 has grown together with the upper chord 201 over a width that corresponds to approximately half the support arch width.
  • the upper belt 201 is largely flat or only flatly curved on its surface in the middle region, but is pulled up in its two end sections to create a footbed (cf. FIG. 11).
  • the lower flange 202 has two end sections 206 which are flat on the underside and which are followed by two upwardly projecting curved sections 207 which are arranged symmetrically to the center and project upwards. These are interconnected by a central section 208 connected, the underside of which is at least approximately in one plane with the end sections 206.
  • the curvature sections 207 protrude approximately up to half the height of the respective profile cross section of the support element 21.
  • the ends of the top flange 201 and the bottom flange 202 are connected to one another by the side support walls 203.
  • the lateral support walls 203 each form an inward concave curvature, i.e. they are inclined inward in their lower half at an angle of approximately 60 ° to the horizontal and then bend outwards again to form a lateral bead-like projection 209.
  • the lower end of the bead-like projection 209 is connected to the upper flange 201 by a support strut 210 connected.
  • the upper chord 201 is further supported on the central section 208 of the lower chord 202 via an oval-ring-shaped support profile 212, which is firmly overgrown with the associated chord both on the top and on the bottom.
  • the thicknesses of the individual components forming the profile or supporting element described above, namely the upper and lower belt, the lateral support walls and the described struts, are approximately 1.5 to 2.5 mm and can also change in the course of the respective individual component. For the sake of simplicity of illustration, they are drawn here essentially uniformly thick.
  • FIG. 9 shows, purely schematically, the deformation behavior of the support element 21 shown in FIGS. 5a, 5 and 11 under a lateral load. If this support element is loaded centrically and vertically from above, for example when the runner is resting on it, the individual components deform correspondingly essentially symmetrically. In the case of the load, indicated by the arrow P, which acts obliquely from above and from the side, on the other hand the support arch 204 is pressed flat on one side and also towards the opposite side shifted something. This displacement leads to an intensification of the support arch curvature in the area opposite to the load P, whereby the support arch at this point becomes stiffer from above compared to the load which is still present.
  • the part of the support element profile opposite the load P therefore maintains its original height due to this stiffening more than would be the case if there was a uniform load across the width of the upper flange 201.
  • This stiffening also has the effect that the relevant cross-sectional part has less deformability to the side, ie the cross-sectional profile is not inclined, in contrast to the behavior of a layered sole consisting of homogeneous material. This corresponds to the anisotropic behavior described at the beginning, which reduces lateral displacement of the shoe bottom and thereby prevents a feeling of swimming.
  • the cover plate 20 which can have a thickness of 1.5 to 2 mm and preferably consists of fiber-reinforced plastic, is firmly connected to the upper chords 201 of the support elements 21 arranged one behind the other by gluing.
  • the cover plate 20 thus forms the holder for the support elements 21, which ensures their mutual distance.
  • the outsole layer 22 has two curved longitudinal ribs 23 which run in the longitudinal direction and converge towards the tip of the shoe, the cross-sectional shape of which is adapted to the contour of the curved sections 207 of the support elements 21 and is also firmly connected thereto by adhesive bonding. Otherwise, the outsole layer 22 is glued to the flat sections 206 and 208 of the lower flange of the support elements 21.
  • FIGS. 6 to 8 corresponds analogously to that of FIGS. 3 to 5 and differs therefrom only with regard to the different design of the support elements 21 '. For this reason, there is no need for a separate detailed explanation of FIGS. 6 to 8.

These support elements also have an upper flange 201', a lower flange 202 ', lateral support walls 203' and a bead projection 209 'on both sides, which is supported by a support strut 210 'on the top chord 201'. In this respect, the outer contour of the box section formed by the support element 21 'essentially corresponds to that of the support element 21.
  • the shape and arrangement of the inner struts of the support element 21 ' are different. These are formed by a support arch 214 which has two curvatures 215 which are symmetrically directed upwards towards the center and a counter-curvature 216 which lies between them and is directed downwards.
