Definitions

  • the invention relates to an outsole for sports shoes, in particular for indoor sports, with the features according to the preamble of patent claim 1.
  • the invention has for its object to design an outsole of the type mentioned so that the risk of ankle twisting is further reduced.
  • the support edge according to the present invention is formed by a bead which is connected to the sole body only by a relatively small part of its cross-sectional circumference, the connection point also being higher than the sole tread surface, extensive lateral mobility of the support edge is achieved. Therefore, lateral forces act on the sports shoes, e.g. when starting or stopping laterally from the barrel, which places a stress on the outer or inner edge of the sole, this mobility of the bead support edge leads to its lateral spreading. As a result, not only is the reaction force, which counteracts the lateral tipping moment, shifted further outward during the load, but this deformation also forms a threshold, which would have to be overcome if it twisted.
  • the threshold effect is particularly pronounced when the bead has considerably larger dimensions compared to the known support edge, e.g. the diameter of its circular cross-sectional area is greater than half the thickness of the shoe bottom. Because in this case the bead can swivel outwards and upwards with part of its upper circumferential surface against the lateral boundary surface of the sole, e.g. Apply to the edge of the shell of a shell sole for support and thereby apply a counterforce that directly counteracts the lateral load. Even if there is no complete installation, the reaction force on the bead acts due to the larger dimensions and the lateral pivoting significantly above the sole contact surface against the tilting moment.
  • the lateral mobility to the outside of the bead is further supported by the fact that the surface of the bead on the step side is smooth and / or low may be higher than the sole tread area. Due to the smooth design, only slight frictional forces counteract the swiveling away outwards and upwards, while the lever arm available for the frictional forces is reduced from the outset when the bead surface on the tread surface is arranged.
  • the intended deformation of the bead is most likely to be achieved when the center of the bead cross-sectional area is either in the extension of the lateral boundary surface of the sole body downwards or outside it. Because then between the side force causing the lateral tipping moment on the sole edge and the described reaction force which acts on the bead, the pair of forces which causes the bead to pivot outwards.
  • the circular cross section of the bead is not strictly tied to a circular shape, but is intended to be any approximately circular, e.g. also describe oval, bead shape, which forms a curved surface on the outside. This curved surface serves to avoid any "braking edge" which could result in the bead not being pivoted outwards when the outsole is loaded laterally, but rather being pressed inwards in the opposite direction.
  • the outsole designated as a whole by 1, of which only the running side is shown in FIG. 1, consists of a sole body 2 and a bead 3 running completely around its edge.
  • the running side of the sole body 2 can be profiled, in particular with one for indoor sports suitable profile.
  • the material of the outsole 1 is one of the conventional elastic sole materials made of plastic or rubber.
  • the outsole 1 can also be either a shell sole which has a - not shown - laterally upstanding shell edge or a shell wall which is connected to the outside of the shoe upper, or a plate sole in which the lateral boundary surface extends only to the lower edge of the shoe extends or at most insignificantly beyond, the connection of the outsole to the shaft mainly via its underside (including the insole).
  • the bead 3 has a circular cross-sectional shape and is connected to the sole body 2 only over approximately a quarter of its cross-sectional circumference.
  • the center M of the circular cross section lies largely on an imaginary extension 4 'down the lateral boundary surface 4.
  • Fig. 2 shows the unloaded state of the outsole, the occurrence side (lower) surface of the bead 3 with its apex line at the same height as the running side 5 of the sole body 2.
  • the bead 3 is offset from the sole body 2 by a groove 6 running parallel to the bead, the groove base 7 of which lies approximately at the center M of the bead cross-sectional area.
  • the flanks of the groove 6 are formed on one side by the sole body 2 and on the other side by the outer surface of the bead 3.
  • the embodiment according to FIG. 3 differs from that described above in that the center point M 'of the cross-sectional area of the bead 3' lies further outside the imaginary extension 4 'of the lateral boundary surface of the sole body 2.
  • the inner flank of the circumferential groove 6 ' is not directed perpendicular to the running side 5, but follows approximately parallel to the facing outer surface of the bead 3'.
  • the threshold effect of the bead 3 or 3 ' is increased with increasing dimensions of the bead.
  • the diameter of the bead should not exceed 1.5 cm.
  • the diameter should not be less than 0.5 cm.
  • a bead 3 or 3 'running around the full circumference of the sole body 2' is shown.
  • this is not mandatory, since an additional support effect is to be achieved in particular with respect to lateral tilting moments, and therefore a limitation of the bead 3, 3 'to the inner and outer edge of the sole can be considered.
  • the ankle since the ankle is bent far more frequently than the inside is bent, it can also be considered to provide the bead only on the outer edge of the sole. If the bead is only partially practiced for the reasons mentioned, it can run into the sole body by increasing its cross section to improve the external appearance of the outsole at the points where a bead should not be provided. Otherwise, it is also possible to adjust the diameter of the bead at those points where there is a particularly high risk of bending, e.g. in the outer ball area to be chosen larger than in the other edge areas on which a bead is formed.
