Definitions

  • the invention relates to a transversely stiffened sole for a shoe.
  • the sole is constructed in such a way that it has a high degree of stiffness transversely to the longitudinal direction of the sole and a high degree of flexibility along the longitudinal direction of the sole.
  • Such soles are, for example, made from DE 91 10 849 U1 known, which describes a flexible, sole-like stabilizing element for the manufacture of shoes.
  • the stabilizing element essentially consists of a sole-shaped, spring-hard metal sheet, which, thanks to its shape, has a high degree of rigidity across the shoe's longitudinal axis and a high degree of flexibility along the shoe's longitudinal axis.
  • the metal sheet is profiled like a corrugated sheet and covered with a soft, elastic rubber or plastic material.
  • the DE 10 2017 116 236 A1 describes an insole or insole for a shoe, which is also designed as a structural sole and is made of spring steel or a comparable plastic material and has a rib-shaped cross-profiling running at an angle to the central longitudinal line, which is designed as a wave profile and consists of a number of consecutive waves.
  • the sole is designed in such a way that it promotes the circulation of air and moisture.
  • the DE 200 05 683 U1 describes an insole for placement in a shoe. It has one or more means for transverse stiffening and/or longitudinal flexibility at least in the forefoot area.
  • the means for transverse stiffening and/or longitudinal flexibility can be incisions provided in a thickening on the underside of the sole, transverse to the longitudinal direction of the sole.
  • the means can be notches formed on the edge of the sole.
  • US 2017/245590A , US 2016/029741A , US 5025573A describe a sole with elongated structures for transverse stiffening.
  • the present invention is based on the object of specifying a sole, i.e. a shoe bottom or a part thereof, for a shoe, which provides a cost-effective and easy-to-produce transverse reinforcement with suitable flexibility in the longitudinal direction of the sole and preferably minimal use of material. Furthermore, it is an object of the invention to specify a method for producing such a sole.
  • the invention is based on a sole for a shoe.
  • the sole can form the shoe bottom or be part of the shoe bottom.
  • the sole or the shoe bottom has at least a forefoot area, preferably also a midfoot area and a heel area.
  • a person's foot is positioned over the sole in such a way that their forefoot is positioned over the forefoot area, their midfoot is positioned over the midfoot area and their heel is positioned over the heel area.
  • the sole further comprises a sole body which, at least in or only in the forefoot area, has a plurality of elongated structures arranged on or in the sole body, such as waves of a wavy profiled plate or individual rods, for transversely stiffening the sole.
  • the elongated structures each have a longitudinal axis.
  • the elongated structures are arranged with their longitudinal axes transverse to the longitudinal direction of the sole, which extends in particular from the heel to the toes.
  • the sole is transversely stiffened by the elongated structures arranged on or in the sole body.
  • the transverse stiffening and longitudinal flexibility are achieved by the plurality of rods arranged in the longitudinal direction, preferably at a distance from one another.
  • the transverse stiffness and longitudinal flexibility are achieved by the waves arranged one after the other in the direction of the waves.
  • a corresponding method for producing a sole for a shoe comprises the step of arranging, at least in a forefoot region, several elongated structures, such as waves of the wavy profiled plate or the individual rods, for transverse stiffening of the sole on or in a sole body in such a way that the longitudinal axes of the rods are arranged transversely to the longitudinal direction of the sole.
  • the individual rods are more cost-effective to produce, use less material and allow easy integration into the sole body.
  • Profiled plates have the advantage that they combine several elongated structures in one part, which simplifies handling when producing the sole.
  • the individual rods can be connected to one or more flexible elements (not part of the sole body), such as a band or rope or a textile layer, in order to position the rods in relation to one another and to simplify handling when producing the sole.
  • the rods can be attached to the underside of an element to be attached or attached above the sole body, such as an insole, with the rods being or being arranged in the recesses of the sole body.
  • the insole and/or the rods can be or be connected to the sole body in a materially bonded manner, such as by gluing.
  • a plurality of elongated structures in particular rods or shafts, i.e. their longitudinal axes, in particular of the forefoot region, can be arranged parallel to one another.
  • all elongated structures or a part thereof, such as at least two, can be arranged parallel to one another.
  • a plurality of elongated structures, in particular all or a part of the elongated structures, of the forefoot region are arranged in such a way that the longitudinal axes of these structures intersect at a point medially, outside the sole.
  • a mixture of parallel and non-parallel elongated structures is also possible. In order for the longitudinal axes to intersect, they can intersect one another or run skewed to one another.
  • At least two elongated structures of the forefoot region can be parallel to one another, wherein at least two elongated structures of the forefoot region can be arranged in such a way that the longitudinal axes of these elongated structures intersect at the point outside the sole.
  • the parallel and/or non-parallel arrangement of the elongated structures in the forefoot area can have a beneficial effect on the rolling behavior of the forefoot area of the sole and thus also of the foot.
  • one, several or each of the elongated structures in the forefoot area can be inclined with their longitudinal axes in relation to the sole longitudinal direction such that the lateral The end of each of these structures is closer to the toe end of the sole than the medial end. This arrangement can have an additional beneficial effect on the rolling behavior of the sole.
  • the bars are arranged at a distance from one another in the longitudinal direction of the sole.
  • the bars or a part of the bars, such as at least two bars, of the forefoot area can be arranged parallel to one another.
  • the longitudinal flexibility in relation to the transverse stiffness and thus the rolling behavior of the sole can be influenced in a simple manner during the manufacture of the shoe, without the need for a new punching tool, as would be the case with corrugated profiled plates or corrugated metal sheets from the state of the art.
  • elongated structures in particular rods or shafts
  • the elongated structures are rods, for example the width extending in the longitudinal direction of the sole and/or the height of the rod can decrease from one end to the other end.
  • the elongated structures are shafts, for example the wavelength extending in the direction of the shaft and/or the height of the shaft can decrease from one end to the other end of the shaft.
  • all or part of the elongated structures can be non-tapering, i.e. with a constant width and/or height.
  • the width extending in the longitudinal direction of the sole and/or the height of the rod can be constant or substantially constant from one end to the other end.
  • the wavelength extending in the direction of wave travel and/or the wave height may be constant or substantially constant from one end to the other end of the wave.
  • the tapered and/or non-tapered arrangement of the elongated structures in the forefoot area can have a beneficial effect on the rolling behavior of the forefoot area of the sole and thus also of the foot.
  • At least two, preferably at least three, four or five elongated structures, in particular rods or waves, can be provided in the forefoot area. It is also preferred that the number of elongated structures in the forefoot area does not exceed ten.
  • the material of the rods can differ from the material of the sole body.
  • the material of the rods can have a higher modulus of elasticity than the material of the sole body.
  • the higher modulus of elasticity can increase the rigidity of the sole in the transverse direction compared to a sole without such rods.
  • Material of the sole body can be arranged between adjacent rods, whereby the longitudinal flexibility is mainly caused by the material of the sole body between the rods.
  • the material of the sole body can, for example, have a modulus of elasticity of 65 to 2,000 MPa.
  • the material of one of the rods or rods can, for example, have a modulus of elasticity of 3,100 to 88,000 MPa.
  • the hardness of the material of the rods can be higher than that of the sole body.
  • the sole body in which the rods are arranged can preferably be made of a plastic or a polymer.
  • a suitable plastic are: ethylene-vinyl acetate copolymer (EVA), polyurethane (PUR), rubber, etc.
  • EVA ethylene-vinyl acetate copolymer
  • PUR polyurethane
  • the rods can be made of metal or a plastic or polymer, for example.
  • the material of the rods are: polyamide (PA), in particular PA 6.6, PA 6.6, glass fiber reinforced plastic (GFK), in particular GFK10-50, polycarbonate (PC), carbon fiber reinforced plastic (CFK), etc.
  • the rods can be round or circular, square or rectangular, trapezoidal, oval or the like in cross-section.
  • the length of the rods or of recesses in the sole body into which the rods are inserted can be dimensioned such that between a medially pointing end of the rod and the medial edge of the sole or sole body and between a laterally pointing end of the rod and the lateral edge of the sole or sole body there is an edge which, for example, has a width from 2 to 15 mm.
  • the edge can in particular be bowl-shaped.
  • the length of the bars and/or the depressions can be such that the bars reach up to the medial and/or lateral outer surface of the sole.
  • the bars in particular their front surfaces, can then be visible from the outside on the edge(s) of the sole and can be perceived, for example, as functional elements.
  • the outer surfaces in particular the medial and/or lateral surfaces of the sole, can be made of a transparent plastic that covers the front surfaces of the bars, but still allows the front surfaces of the bars to be seen from the outside.
  • the sole body can have several, preferably upward-facing, alternatively downward-facing, in particular elongated depressions, wherein one of the rods is arranged in each of the depressions and in particular is connected to the sole body in a material and/or form-fitting manner.

After the recesses have been molded or introduced, one of the rods can be inserted into the recesses and connected there to the sole body in particular in a material-locking manner, such as by gluing, and/or in a form-fitting manner, for example by snapping.
  • the rods or the wavy profiled plate are introduced into a mold, in particular an injection mold, and are encased, in particular overmolded, in a material to form a sole body. Accordingly, the rods can be encased in the sole body, in particular overmolded with the material of the sole body. Encasing or overmolding the rods with the material of the sole body has the advantage that the rods no longer have to be inserted separately into the recesses after molding and connected there with the sole body in a material-locking or form-fitting manner.
  • the injection molding tool with which the rods are connected with the material of the sole body are wrapped, more complex to manufacture. The tool for the process in which the sole body is provided with several recesses and the rods are inserted into the recesses after molding is less expensive, but the step of inserting the rods into the sole body is required.
