Definitions

  • the present invention relates to a sole for safety shoes, in particular according to DIN 4843 or EN344, according to the preamble of claim 1.
  • the invention also relates to a sole equipped with a sole according to the invention Safety shoe.
  • the standards DIN 4843 and EN 344 mentioned require a safety shoe penetration-resistant insert (e.g. according to DIN 32768) in the form of a midsole Steel to the foot especially in the construction area in front of pointed objects, such as To protect nails etc.
  • the midsole must be worked into the under shoe be removed without damaging or destroying the shoe can be.
  • DE 31 08 359 A1 describes a sole for safety shoes, which has a puncture-proof sheet steel insert, which is between the outer and the inner layer of the sole is arranged.
  • the deposit is correct with regard to their Surface shape at least approximately matches an inner layer of the sole.
  • the disadvantage of the known sole is that there is still no optimal protection in particular is present in the area of the arch of the foot, so that it is safe from penetration Insert to foot injuries caused by pointed objects can.
  • DE 909 070 it is known from DE 909 070 to have one in the front part of the shoe Toe protection made of metal and a metal plate in the insole.
  • the size of the metal plate corresponds to the size of the toe protection and has one bent edge that overlaps the edge of the toe protection.
  • disadvantage The solution known from DE 909 070 is that only in the area of the toes, but not in the remaining sole area protection against penetrating elements is achieved.
  • the invention is therefore based on the object, starting from the above State of the art to create a sole that has a significantly increased security against foot injuries especially in the arch area of the foot at the same time good comfort guaranteed.
  • this object is achieved by a sole according to claim 1.
  • the surface of the vertical projection of the foot is advantageous including the inner arch of the foot almost completely, but in any case very much largely, covered by the midsole from below and thus the foot optimally protected against pointed objects that penetrate the outsole.
  • the midsole prevents penetration of the entire outsole, but also leads to increased security against perforation of the Shaft through pointed objects "past the outsole" in the so-called waist area the sole, since advantageously e.g. Nails or the like of the invention Extension section so that they are deflected at the foot to be led past.
  • the invention is based on the one hand on the knowledge that in the conventional Safety shoes foot injuries especially in the inner metatarsal area occur. Now was assume that a corresponding increase in the Steel midsole to adversely stiffen the entire sole in the midfoot area and therefore too unfavorable Wearing properties especially with regard to the would cause the foot to roll when walking.
  • the invention lies the further knowledge based on the fact that through the "established" expansion approach actually a substantial stiffening of the sole occurs in the midfoot area, but this even becomes one beneficial support and guidance of the foot leads. So was found through tests with test subjects that the Stiffening at least not as a disadvantage, in most Cases even found to be advantageous or not at all has been. Furthermore, the stiffening of the midsole leads Surprisingly, neither did it increase Risk of breakage, as would have been due to the reduced elasticity can be expected because join in the joint area the rolling motion no impermissibly high material stress on.
  • the midsole is opposite one the midfoot area in particular via a double bend or via a corresponding crank in the direction move a tread of the outsole down Has heel section.
  • the Heel and midfoot area practically a kind of "joint" formed, which makes for extremely good rolling comfort Walking movement leads and especially in combination with the Orthopedic support for the midfoot is very beneficial.
  • a safety shoe according to the invention 1 from an upper shoe 2 and a lower shoe 4 with a Sole arrangement consisting of an outsole 6, an insole 8 and preferably a removable insole 10.
  • the Outsole 6 has any profile on its underside 12 on.
  • the upper shoe 2 consists - in a manner known per se - of a suitable upper material 14, usually leather, a lining 16, a metatarsal cushion 18, a lacing 20 with a dust flap 22, a front safety toe cap 24, a rear cap 26 and preferably one Ankle padding 28.
  • a suitable upper material 14 usually leather, a lining 16, a metatarsal cushion 18, a lacing 20 with a dust flap 22, a front safety toe cap 24, a rear cap 26 and preferably one Ankle padding 28.
  • the lower shoe 4 now has a puncture-proof insert in the form of a steel midsole 30, which is preferably in the material of the outsole 6 is embedded.
  • the midsole has 30 according to the invention - starting from their usual, to the contour of the outsole 6 or the insole 8 adapted and therefore in the midfoot area with a "Waist" provided surface shape - at least in the area of Inner arch of an extension 32, which itself extends at an obtuse angle ⁇ angled upwards (see Fig. 3 and 6).
  • the angle is ⁇ preferably about 90 ° to 150 °.
  • FIGS Invention has the midsole 30 in the area of The outer arch of the foot has a corresponding, second extension approach 34 on which is inclined at an obtuse angle ⁇ is angled upwards.
  • the angle ⁇ is also preferred in the range between 90 ° and 150 °, but does not have to the angle ⁇ agree in any case.
  • the respective inner or outer arch of the foot is also arched is formed and preferably a convex has an arcuate outer edge 36 (see FIGS. 2 and 5).
  • the Radius of curvature R of the outer edge 36 is preferably about 50 to 70 mm, in particular about 60 to 62 mm.
  • the maximum height H of the respective extension approach 32 or 34 is the height or thickness of the respective outsole 6 adapted; with thicker outsoles it can be higher than with thinner outsoles. In the example shown is 3 in particular about 7 mm.
  • the steel midsole 30 consists of a front and Metatarsal area 38 and one opposite in the direction the underside profiling 12 of the outsole 6 offset heel section 40. Between these two Sections 38 and 40 is preferably a double bend or offset 42 formed, see Fig. 1 and 4th
  • the midsole 30 is made from a flat sheet metal stamped part produced, as shown by way of example in FIG. 5. Starting from this level state, the extension approach 32 and possibly also the second extension approach 34 in a suitable tool in the direction of the drawn Arrows 44 bent up. Furthermore, the heel section 40 cranked down over the bend 42.
  • the invention is not based on the illustrated and described Embodiments limited, but also includes all designs having the same effect in the sense of claims 1-6.
