Definitions

  • the invention relates to a heel wedge according to the preamble of claim 1.
  • Such a heel wedge has become known from AT-PS 375 248, which on the one hand should give the foot a firm hold and on the other hand should fix the given shape of the shoe in the long term.
  • this heel wedge is not intended as a spare part, but rather as a rear cap to be used in the manufacture of the shoe.
  • This is made of a thermoplastic film with a laminated foam layer made of a closed-cell foamed, cross-linked polyolefin layer. This material of high inherent stability is deep-drawn in a stamping / pressing tool in the shape of a horseshoe, the thickness of the foam layer being tapered in a wedge shape in the same work step by compression of the pore structure.
  • High-density polyethylene, but also a film made of ABS or PVC can be used as the thermoplastic film.
  • a similar heel wedge also not designed as a spare part, but rather as a rear cap to be used in the manufacture of the shoe, is known from FR-A-2 448 310. It is made of a rigid or semi-rigid material and is thickened towards the bottom to give the heel a better grip. The thickening can be caused by lamination of the same or a different material, but also if the heel wedge is made in one piece.
  • the invention has for its object to develop an inexpensive, the running process not hindering, simple spare part, which can be retrofitted into the footwear without great effort and forms a stiffening cap replacement, through which the previously described shortcomings are reversed.
  • the heel wedge according to the invention is characterized in particular by the fact that it can be elastically / plastically deformed by appropriate choice of material, as a result of which the heel wedge can be adapted to the respective size of the footwear. So there is only one heel wedge spare part for all shoe sizes in stock.
  • the plastic used is expediently transparent, as a result of which the basic coloring of the shoe visually colors the heel wedge after installation and thus gives an aesthetically satisfactory result.
  • the outer surfaces of the heel wedge have a roughened surface structure with a roughness depth of appropriately 60 to 100 ⁇ m.
  • the heel wedge according to the invention can advantageously be produced as an injection-molded plastic part if there is no undercut.
  • a horseshoe-shaped heel wedge 1 with raised outer contours 13 is proposed, which fills the cavity between the heel 3 of the foot 4 and the angular inner heel contour 5 of the footwear 6.
  • the design of the curved inner shape 7 and the angular, semicircular outer shape 8 of the heel wedge 1 correspond on the one hand to the anatomical shape of the human heel 3 and on the other hand to the heel inner contour 5 originally specified by the footwear 6.
  • amorphous thermoplastic with a plasticizer additive is used as the material for the heel wedge 1, preferably polyvinyl chloride with a plasticizer additive of 27 ⁇ 2% type DOP or DI-2-ethyl phthalate.
  • the preferred Shore A hardness is 90 ⁇ 5 according to DIN 53305.
  • the heel wedge 1 is thereby elastically / plastically deformable and it can be adapted to the respective size of the footwear.
  • the outer surfaces 8 of the heel wedge 1 have a roughened surface structure 14 with a roughness depth of preferably 60 to 100 ⁇ m, which produces a better and more intensive connection of the heel wedge 1 by gluing to the insole 9 on the one hand and the heel lining or heel upper 10.
  • the horseshoe-shaped inner region 11 of the heel wedge 1 can be bridged by a thin-walled, continuous base plate 12. To adjust the size to the respective To not hinder footwear 6, this base plate 12 should be interrupted by a wedge-shaped or semicircular recess 15.
