Definitions

  • the invention relates to a shoe, in particular a sports shoe, with a shoe upper and a sole, wherein the sole has a wearer associated with the shoe upper or inner part, connected to the carrier or inner part midsole and an outsole connected to the outsole, wherein the Midsole contains a damping element at least over part of the ground-tread surface of the shoe or is formed as a damping element having a number of juxtaposed first elements which extend substantially in a loading direction in the unloaded state of the damping element over a predetermined height and, as a hollow body designed to define a receiving space, in which an associated second element, in the cross-section of smaller dimensions than the first element can at least partially penetrate, wherein the second element is substantially in the loading direction in the unloaded state of the damping element extends over a predetermined height and is arranged coaxially with the first element.
  • a shoe of this kind is from the WO 03/092423 A1 known.
  • the WO 03/092423 A1 describes for this purpose a damping element of the type mentioned, in particular for a sports shoe, which has a special structure.
  • the damping element has a plurality of juxtaposed individual elements, each forming a spring and damping chamber in the manner of a piston-cylinder system. In the form corresponding first and second elements are connected to each other via a connecting portion, wherein upon loading of the sole, the smaller formed element enters the larger, which forms a receiving space for this purpose.
  • Such a damping element is according to said solution primarily intended to be integrated into a midsole, for which there are other models in the prior art. This is on the EP 0 387 505 A1 which discloses a honeycomb-shaped damping element, which is inserted into a receiving space in the midsole of the shoe.
  • the invention has for its object to provide a shoe, in particular a sports shoe, whose spring and damping properties influenced more and are thus adjusted according to predetermined wishes can. This should be done inexpensively and easily in terms of manufacturing technology.
  • the massively formed region of the second element is advantageously arranged at least in the end region of the second element remote from the first element.
  • the massively formed region of the second element has a concave surface. This may be part of a spherical surface or part of the surface of an ellipsoid.
  • the midsole may be formed exclusively as a damping element over at least part of the bottom tread surface of the shoe, d. H.
  • the outsole may be formed by a number of individual sole parts, wherein each sole part at the end facing away from the first element of the second element or at the end facing away from the second element of the first Elements is arranged. Furthermore, it can be provided that the shape of the individual parts of the outsole corresponds to that of the second element or that of the first element in a section perpendicular to the loading direction.
  • each form a first element and a second element together with the connecting portion a gas-tight chamber.
  • the first element and the second element may have a mutually corresponding shape in a section perpendicular to the loading direction.
  • the first element and the second element have a polygonal, in particular hexagonal, shape in a section perpendicular to the direction of loading.
  • the first elements may be interconnected in their lateral region or their lateral boundary walls may each be formed from a common section.
  • the first and / or second elements preferably have different heights, at least partially in the unloaded state of the damping element.
  • the connecting portion may be flat or curved in the unloaded state of the damping element in a plane perpendicular to the loading direction. With the latter embodiment, the entry of the "piston” is favored in the "cylinder" under load.
  • first element, the connecting portion and the second element are integrally formed, it is advantageously provided that the first element, the connecting portion and the second element are produced by a common injection molding process.
  • the midsole provided with the damping element or formed by these can absorb energy when loading the sole in the direction of loading and release it again on relief of the sole.
  • the lower axial end region of the first element and the upper axial end region of the second element are connected to one another via the connecting section. It is at the connecting portion - as well as the first and second element - is a part of elastic plastic material, so that upon application of a loading force on the damping element in the loading direction takes place a deformation.
  • the second element occurs like a piston in the receiving space of the first element.
  • the second element facing away from the end of the first element can be connected to a sealing film, in particular welded thereto.
  • a sealing film in particular welded thereto.
  • the elements are preferably made of plastic, in particular of thermoplastic material.
  • plastic in particular of thermoplastic material.
  • preference is given to polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these plastics.
  • the plastic can be translucent or transparent.
  • the outsole may be made of plastic, preferably polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these plastics, or rubber, wherein the material is not translucent or not transparent.
  • the material of the first element, the second element and the connecting portion and / or the geometric dimensions of these parts and / or the volume fraction of the solid part can be selected to determine the spring and / or damping properties of the damping element.
  • the resulting spring stiffness of the damping element can be influenced by the choice of the volume fraction of the solid part; a higher volume of the solid part results in a higher spring rigidity.
  • the first element is in the unloaded state of the midsole with its axial extent substantially outside the axial extent of the second element.
  • the piston-like second element is arranged in the unloaded state of the midsole axially outside of the cylinder-like first element. Only when loading the damping element in the loading direction then enters the "piston" in the "cylinder".
