Definitions

  • the invention relates to a shoe, in particular a sports shoe, with a shoe upper part and a sole, where the sole has a support part or inner part connected to the shoe upper part, a midsole connected to the support or inner part and an outsole connected to the midsole.
  • WO 03/092423 A1 discloses a damping element, having a specific structure, for a shoe, in particular for a sports shoe.
  • the damping element has a large number of individual elements which have been arranged alongside one another and which respectively form a springing and damping chamber in the manner of a piston-and-cylinder system.
  • First and second elements of corresponding shape have connection to one another by way of a connecting portion and when the sole is under load here the smaller element enters into the larger element, which forms a receptacle for this purpose.
  • An object underlying the present invention is to provide a shoe, in particular a sports shoe, which features a simpler method of production, but without omitting the advantageous property of the previously known damping element. In particular, it is to be possible to retain control of the springing and damping performance of the shoe.
  • the midsole is, at least across a part of the ground-contact area of the shoe, exclusively a damping element, which has a number of first elements arranged alongside one another which in essence extend across a prescribed height in a direction of loading in the unloaded condition of the damping element and, being hollow bodies, define a receptacle into which an associated second element, smaller in cross-sectional dimensions than the first element, can penetrate at least to some extent, where the second element in essence extends across a prescribed height in a direction of loading in the unloaded condition of the damping element and has been arranged coaxially with respect to the first element.
  • the starting point of the inventive concept is therefore that the damping element previously known per se is used in such a way that the midsole is formed exclusively therefrom—at least across a part of the area of the midsole.
  • the outsole is formed via a number of individual sole parts, where each sole part has been arranged at that end of the second element that faces away from the first element.
  • the outsole is then segmented; each “piston” of the piston-and-cylinder elements of the midsole becomes associated with a part of the outsole in the region of contact with the ground.
  • the shape of the individual parts of the outsole here preferably corresponds to that of the second element—in a section perpendicular to the direction of loading.
  • the second element is also a hollow body according to one embodiment.
  • the second element is an entirely solid or at least substantially solid part.
  • the two elements associated with one another have connection to one another by way of an elastic connecting portion, which extends merely between the first element and the second element. It is also possible that respectively a first element and a second element, together with the connecting portion, form a gastight chamber.
  • the first and the second element have a mutually corresponding shape in a section perpendicular to the direction of loading.
  • the shape here is especially polygonal, in particular hexagonal; a circular shape is also possible. This means that the cross-sectional geometry of the first and of the second element are mutually congruent, thus providing, in the first element, a receptacle which fits the second element.
  • the axial length of the first element is in essence outside of the axial length of the second element.
  • the piston-like second element has been arranged axially outside of the cylinder-like first element. The “piston” then enters the “cylinder” only on loading of the damping element in the direction of loading.
  • first elements have connection to one another in their lateral region, or their lateral boundary walls are respectively formed from a shared portion.
  • each element can also be manufactured as a separate component and then assembled.
  • first and/or second elements have at least to some extent, in the unloaded condition of the damping element, different heights.
  • the profile of the connecting portion can be flat or else curved in a plane perpendicular to the direction of load in the unloaded condition of the damping element. The latter embodiment favours entry of the “piston” into the “cylinder” on loading.
  • first element, the connecting portion and the second element are one-piece items. It is possible here that the first element, the connecting portion and the second element have been produced via a shared injection-moulding process.
  • That end of the first element that faces away from the second element can have connection to a sealing foil.
  • a gastight condition of that end of the second element that is distal with respect to the first element can be achieved via the outsole segment placed thereon.
  • the preferred material that can be used for the elements is plastic, in particular thermoplastic.
  • plastics that have proven successful are—as is known in the prior art—polyethylene, polypropylene, polybutene, polyamide, polyurethane, or a mixture of at least two of these plastics, and the plastic of the midsole here is particularly preferably translucent or transparent.
  • a plastic of this type can likewise be used for the outsole, but it is preferable that the material here is not translucent or is not transparent.
  • the material of the first element, of the second element and of the connecting portion and the geometric dimensions of these parts, have been selected in order to establish the damping properties of the damping element.
  • the number of mutually adjacent or mutually connected damping elements itself provides the midsole, and it is exclusively these elements that form the midsole. If appropriate, that end of the second elements that faces away from the support part or inner part can be sufficiently wear-resistant and/or stiff and/or thick that this end region of the second elements functions and acts as an outsole, i.e. that there is then no separate outsole element attached to the end of the second element.
  • the midsole can absorb energy on loading of the sole in the direction of loading and in turn dissipate it on removal of load from the sole.
  • the lower axial end region of the first element and the upper axial end region of the second element have connection to one another by way of the connecting portion.
  • the connecting portion is—as also are the first and second element—a part composed of elastic plastics material, and therefore when a load force is applied to the damping element in the direction of loading a deformation takes place.
  • the second element enters, in the manner of a piston, the receptacle of the first element.
  • That end of the first element that faces away from the second element can be connected to a sealing foil, in particular can be welded thereto.
  • the first element, the second element, the connecting portion and the sealing foil form a gastight sealed space, which has ideal springing and damping properties.
  • the springing and damping characteristic of the damping element can be adjusted or selected as desired via appropriate adjustment of the geometry of the sole elements and in particular of the heights and widths of the first and second elements, via the selection of the thickness and design of the connecting portions, and finally via the selection of the material of which these parts are composed.
  • the springing and damping characteristic of the damping element in particular the springing force as a function of spring displacement—can thus be selected substantially in accordance with a desired curve.
  • the drawing shows an inventive example.
  • FIG. 1 shows a diagram of a shoe, seen from the side
  • FIG. 2 enlarges the detail “Z” according to FIG. 1 and
  • FIG. 3 shows the section A-B according to FIG. 2 .
  • FIG. 1 shows a shoe, namely a sports shoe, but only very diagrammatically.
  • the shoe has a shoe upper part 1 , which has connection to a sole 2 .
  • the sole 2 extends over a certain area in the front sole region 8 . It likewise extends over a defined area in the rear sole region 9 .
  • FIG. 2 gives more detail of the structure of the sole 2 .
  • the sole 2 is composed of three (sole) parts, namely a support part or inner part 2 ′, a midsole 2 ′′ and an outsole 2 ′′′.
  • the support part or inner part 2 ′ can be an insole, a Strobel sole or actual shoe-upper material, forming the connection between the shoe upper part 1 and the midsole 2 ′′.
  • One particularly preferred embodiment provides that the support part or inner part 2 ′ has been manufactured as a plastics injection moulding (preferably composed of EVA) and has the shape of a shell.
  • the support part or inner part 2 ′ has connection to the shoe upper part 1 .
  • the connection can, by way of example, be produced via an injection-moulding process, by injecting the plastics material that forms the support part or inner part 2 ′ onto the upper part 1 composed, by way of example, of textile material. It is equally possible to adhesive-bond shoe upper part 1 and support part and inner part 2 ′.
  • the midsole 2 ′′ is composed of a large number of damping elements, whose structure is like that of a piston-and-cylinder system.
  • the outsole 2 ′′′ has been arranged at that end of the midsole 2 ′′ distal with respect to the support part or inner part 2 ′, and is composed of a number of sole segments 2 ′′′ corresponding to the number of the damping elements.
  • the structure of the entire sole does not have to be as explained.
  • the underlying shape of the individual damping elements which form the midsole 2 ′′—viewed in the direction R of loading of the sole 2 — is hexagonal and honeycomb-like (see FIG. 2 ).
  • Each damping element has a first element 3 , which extends across a defined height H and forms a receptacle 4 .
  • a fillet-shaped connecting portion 6 that end of the first element 3 that faces away from the support part or inner part 2 ′ has connection to a second element 5 , whose shape corresponds to the shape of the first element 3 —viewed in the direction R—and this means that the second elements 5 also have a hexagonal shape in the inventive example.
  • the second element 5 extends across a height h which does not have to be the same as the height H.
  • the first element 3 and the second element 5 therefore operate in the manner of a telescopic damper, where the first element 3 functions as a “cylinder” into which the second element 5 can enter in the manner of a “piston”.
  • An outsole segment 2 ′′′ has been attached to, e.g. adhesive-bonded to, or else directly injection-moulded onto, that end of the second element 5 that faces away from the support part or inner part 2 ′, and is composed, by way of example, of abrasion-resistant plastics material. Viewed in direction R, the shape of the outsole segment 2 ′′′also corresponds to that of the second element 5 , although this does not necessarily have to be the case.
  • the space enclosed by the first element 3 , connecting portion 6 and second element 5 can be gastight, thus exerting a favourable effect on spring-deflection behaviour.
  • a gastight condition with respect to the support part or inner part 2 ′ can be produced via a foil 7 , which, if required, is adhesive-bonded or welded to that end region of the first elements 3 that faces toward the support part or inner part 2 ′.
  • the outsole is practically always an element extending over an area and forming at least a substantial region of the area of contact with the ground, the outsole provided here is therefore a segmented outsole secured to the second elements.
