Definitions

  • the invention has for its object to provide a sole of the type mentioned in such a way that the shoe offers sufficient sure-footedness and stability in unpaved terrain, especially on loose, sandy ground.
  • the combination of the relatively coarse lug profile with the fine lamella profile ensures a high level of footing and stability in any terrain, especially on loose, sandy ground.
  • the slats of the slat field can easily claw into the loose surface due to their elastic deformability and thus offer a secure hold.
  • the lamella field increases the contact area between the sole and the ground, which also contributes to an increase in stability and / or sure-footedness.
  • the statement that the lamellae run transversely to the running direction also includes an angle of up to approximately 45 ° to the running direction.
  • At least one column following a lamella have a depth t measured from the lower surface of the gallery. The lamella can then only be deflected towards the column until it rests on the lower edge of the column.
  • the lamella field adjoins a lamella-free and gap-free surface section of the lower surface of the cleat along at least one boundary line.
  • the lamella field may adjoin a plurality of lamella-free and gap-free surface sections of the lower surface of the gallery along several boundary lines.
  • the lamella field it is possible for the lamella field to be arranged in the middle of a gallery.
  • the slats of the slat field can have different vertical cross sections. So it is possible on the one hand that the slats of the field have a substantially rectangular vertical cross section or on the other hand a vertical cross section pointed downwards and backwards.
  • the latter variant has the particular advantage that the slats penetrate better into the loose surface and can thus ensure good power transmission between the foot and the surface.
  • the studs be arranged along the circumferential contour of the sole and that the lamella fields arranged on the stud bottom surfaces adjoin the edge of the stud bottom surface remote from the contour.
  • This type of combination of the stud profile with the lamella fields achieves an optimal profile of the sole adapted to the requirements when the foot appears.
  • the respective outer parts of the foot first come into contact with the floor. If the foot is then subjected to a further load, for example in order to achieve a better hold, the contact area of the foot increases toward the inner arch of the foot.
  • the coarser profile of the sole first comes into engagement with the ground and, if this has not yet achieved sufficient footing and stability, then the finer lamella profile when subjected to further stress.
  • the lamella width measured in the running direction be approximately 1 to approximately 3 mm, preferably approximately 2 mm. It is proposed for the slat length that this corresponds to approx. 5 to approx. 10 times the slat width. A value in the order of magnitude of approximately 1 mm to approximately 3 mm, preferably 2 mm, is proposed for the lamella spacing measured in the running direction.
  • the studs and / or ribs are relatively far apart from one another in the running direction. Small stones can therefore settle in the spaces between two successive tunnels or ribs. With each occurrence, these stones press through the sole and through a possibly existing intermediate layer into the inside of the shoe, so that they can be felt more or less clearly on the foot surface. These pressure points affect the feeling of walking and can even lead to blisters or blood blisters.
  • an ejector web running essentially transversely to the direction of travel is provided in the bottom of an intermediate space between two tunnels which follow one another in the running direction, the height of which is smaller than the height of the tunnel measured from the bottom of the intermediate room.
  • the proposed solution ensures that a stone that has penetrated is ejected through the ejector web either due to pressure compression or due to elastic deflection at the latest when the space is widened with a corresponding deformation of the sole, at least beforehand.
  • the statement that the ejector web runs transversely to the running direction also includes an angle of up to 45 ° to the running direction.
  • the ejector web have the shape of a triangle in a vertical cross section.
  • the triangular base is smaller than the width of the space base, which ensures an elastic deformation of the triangle.
  • the triangle height is at most equal to the triangle base.
  • the ejection movement through the ejector web is additionally supported in that the stud side surfaces are inclined towards an adjacent vertical surface, specifically away from the central plane of the ejector web.
  • an intermediate sole layer is provided between the inner surface and the top of the sole, which is intended to have a damping effect.
  • the intermediate layer of the sole is usually applied by a vulcanization process on the upper side of the sole. Since relatively large forces can be transmitted between the sole and the foot, only the vulcanization can lead to detachment of the intermediate layer of the sole.
  • anchoring ribs are formed on a lower surface of the sole substantially parallel to this shoe connection surface, which extend essentially transversely to the running direction and extend from the edge of the sole.
  • the anchoring ribs By means of the anchoring ribs additionally provided on the upper side of the sole, which forms the shoe connection surface, a force transmission between the shoe sole and the intermediate layer is achieved, which relieves the connection between the sole intermediate layer and the sole, which is achieved by vulcanization.
  • the statement that the anchoring ribs run transversely to the running direction also includes an angle of up to 45 ° to the running direction.
  • anchoring ribs be covered on the edge side by a raised shoe edge section which appears visibly on the finished shoe from the outside.
  • the soles In the known leisure and sports shoes, the soles have a pronation area near the heel and a supination area near the ball and are profiled at least in sections on the underside forming the tread, the profile comprising cleats.
  • Such soles are mostly made of elastic for cushioning purposes Made of material. The softness of the material is limited by the requirement that the sole must have a certain abrasion resistance.
  • An intermediate sole layer is arranged between the sole and the upper, but the overall softness of this sole construction is limited.
  • the tunnels located outside the pronation and supination area form cavities on the upper side of the sole which are intended for filling by material of an intermediate layer of sole applied on the upper side of the sole.
  • the intermediate sole layer can be, for example, a foam wedge. This achieves an additional damping effect, but a relative stiffness is retained in the pronation or supination range, which is particularly crucial for the transmission of force.
  • a sole according to the invention is generally designated 10. It is preferably made of a rubber mixture with a Shore hardness A of 70 and has an outer peripheral contour adapted to the anatomical shape of a foot. Cleats 12 are arranged in sections on their sole underside 11 forming the tread.
  • studs 12 protrude outward from the bottom of the sole by the same amount. They each have different horizontal cross sections, but can also have identical cross sections.
  • the lugs 12 arranged along the outer circumferential contour of the sole 10 are provided with a lamella field 14 on the lower lug surface 13 running parallel to the sole lower surface 11.
  • the lamella fields 14 are arranged on the edge of the respective stud 12 remote from the outer peripheral contour.
  • the lamella field 14 consists of individual lamellae 16, which are arranged substantially transversely to the running direction and arranged one behind the other in the running direction and protrude elastically deformable from the plane of the lower surface 13 of the stud 12 by a height h. Between each two slats 16 there are gaps 18 which, measured from the lower surface 13 of the stud 12, have the depth t. The total vertical extent between the lower edge of the slats and the bottom of the column is therefore equal to the sum (h + t) of the height h and the depth t (FIG. 2). Typically, the lamella field 14 begins and ends with a lamella 16.
  • the lamella field 14 begins with a lamella 16 and ends with a column 18. Another variant is indicated by the arrow B in FIG. 2. There, the lamella field 14 begins with a column 18 and can then end either with a lamella 16 or with a column 18.
  • each lamella 16 has a rectangular shape.
  • a lamella field 14 ' is shown, the lamellae 16' have a downward and counter to the running direction tapered back vertical cross section. The direction of travel is indicated by an arrow C in FIG. 2a.
  • the slat width and the distance between two slats 16 is 2 mm.
  • the slat length corresponds to approximately 5 to 10 times the slat width.
  • Ejector webs 22 are arranged in an intermediate space bottom between the cleats 12 arranged along the circumferential contour of the sole 10. These have an equilateral triangular shape in their vertical cross section.
  • the triangular base is smaller than the width of the space base 21.
  • the side flanks of the ejector webs 22 merge into the side surfaces 26 of the studs 12 facing the ejector webs 22.
  • the side walls 26 are inclined against an adjacent vertical surface, specifically away from the central plane of the ejector webs 22.
  • the length transversely to the running direction of the ejector webs 22 corresponds to the length of the space base 21.
  • the sole 10 In the area of the ball of the foot, the sole 10 has a supination area 28 and in the area of the heel a pronation area 30. These two areas are separated from the remaining sole 10 by a boundary line 29. They can have a different material mixture than that of the remaining sole 10.
  • the material mixture of the supination and pronation region 28, 30 should preferably be softer than the material mixture of the remaining sole 10. It has a Shore hardness A of approx. 60.
  • cavities 38 aligned with the studs 12 are arranged (FIGS. 4, 5).
  • the cavities 38 are adapted in their inner contour to the outer contour of the studs 12.
  • Foam material preferably polyurethane foam with a Shore hardness A of approximately 45, an intermediate sole layer 32, which is applied on the upper side 31 of the sole, can additionally be accommodated in them.
  • the sole 10 according to the invention is suitable for a wide variety of uses, such as paved and unpaved terrain.
  • a particularly favorable damping of the sole 10 is achieved through the additional cavities 38.
