Definitions

  • the present invention relates to a shoe substructure, especially for safety shoes according to EN 344/345 or DIN 4843, with one in the heel or heel area arranged energy absorption element.
  • section 4.3.6 is for safety shoes required that in the heel area an energy absorption capacity is guaranteed, which is not less than 20 J may be.
  • the present invention has for its object a Substructure for shoes, especially safety shoes, to create with the good, especially even improved wearing comfort the energy absorption capacity in the Heel area can be increased significantly.
  • this is achieved in that the energy absorption element with at least the heel or Damping element covering the sales area to form a energy-absorbing and cushioning comfort element is.
  • a shoe substructure 1 according to the invention (so-called substructure) comprises an energy absorption element in both embodiments, which is arranged in the heel or heel area is and preferably also about the shape of a later sole heel corresponds.
  • This energy absorption element 2 is now in accordance with the invention one at least also the heel or heel area covering damping element 4 to an energy-absorbing and damping comfort element 6 connected.
  • the energy absorption element 2 below, i.e. on the side facing away from one foot, and the damping element 4 at the top on the side facing the foot.
  • the surface of the damping element 4 facing the foot is preferably also arched according to the arch of the foot (concave), which is achieved in the usual way by a last can be.
  • the energy absorption element 2 consists of such a hard set material, especially a thermoplastic Plastic, such as SB (styrene-butadiene copolymer), that it has an energy absorption capacity of 30 to in particular guaranteed about 35 joules - measured according to the Procedure according to EN 344, section 5.10.
  • SB styrene-butadiene copolymer
  • the damping element 4 consists of a material in the hardness range preferably about 30-40 Shore. It is highly elastic with a very high rebound effect, which is a squeeze and prevents fatigue. It is suitable for this especially a thermoplastic, in particular also SB, which ensures high pressure elasticity can.
  • the energy absorption element 2 and the damping element 4 basically of the same material, preferably SB, exist, the different mentioned Material properties through certain selection and composition of the material components achieved. So increase small butadiene shares, for example, the blow and Notched impact strength of the polystyrene.
  • the energy absorption element 2 and the damping element 4 exclusively force and / or are positively connected, i.e. without material closure or gluing.
  • This can be an advantage can be achieved in that the one element shown in Example the damping element 4, connection approaches 8, which in corresponding receiving openings 10th of the other element, as shown the energy absorption element 2, in particular intervene.
  • a non-positive, but still very good connection can be achieved with advantage that the connection approaches 8 and the receiving openings 10 in the manner of so-called "self-locking cone connections" trained are.
  • the strength or durability of the connection is hereby essentially determined by the cone angle.
  • a cone angle of approximately 5 to 10 ° is advantageous here.
  • several, for example five to fifteen, connecting lugs 8 and receiving openings 10 provided, it is in the illustrated embodiment each by nine.
  • the production is particularly simple because of the components the comfort element 6 only to be compressed need.
  • the insole is preferably at least in their covering the through openings 14 Surface area designed to be permeable to air, for example can be achieved by perforating the insole or is slotted.
  • the comfort element 6 in the first embodiment illustrated in FIGS. 1 to 5 is now the comfort element 6 according to the invention with a hinge part 18 made of a relatively hard plastic connected, this joint part 18 a heel area 20 and one that extends into the midfoot area, expediently to the arch of the foot or one Last adapted support region 22.
  • this joint part 18 in its heel area 20 like a frame with a receiving opening 24 for in particular force and / or positive reception of the comfort element 6, in particular the energy absorption element 2 is.
  • the Energy absorption element 2 only in the direction of arrow 26 in the receiving opening 24 of the joint part 18 inserted become.
  • the comfort element 6 connected to a steel midsole 28 which in the case of a safety shoe according to EN 345, category S3 serves to increase penetration security.
  • the midsole 28 with a heel section 30 in one slot or groove-like receptacle 32 of the comfort element 6, in particular the energy absorption element 2, held non-positively and / or positively. This takes the heel section 30 only in the direction of the arrow 34 Fig. 7 to be inserted into the receptacle 32.
  • the damping element 4 expediently - starting from his with the energy absorption element 2 connected heel section 36 - one extending portion toward the midfoot 38 on who is preferably in his Thickness continuously up to the surface of the support area 22 of the Joint part 18 (Fig. 1 to 5) or up to the surface in Midfoot area of the steel midsole 28 (FIGS. 6 to 8) rejuvenated. Walk in the assembled, "plugged" state consequently the surfaces are constantly intermeshed, being total a concave curvature adapted to the arch of the foot is provided.
  • damping element 4 from a preferably 2.0 to 5.0 mm thick energy absorption mass exists that dampens the appearance and for whom the whole Heel area covering comfort ensures walking.
  • the substructure 1 according to the invention leads through the functional assignment of the individual parts to special good properties, groin specifications fit the anatomy of the foot, improves the foot climate as well for optimal comfort in connection with the relevant standards of improved energy consumption.
